MXPA99005276A - Suspension crystallization method - Google Patents

The invention concerns a method of separating organic compounds by single- or multi-stage suspension crystallization, each stage consisting of a crystallizer, optionally a crystallizer vessel, and a filter (7) for separating the liquid phase from the crystal mass. The liquid phase (8) separated in the filter (7) is returned to the respective crystallization stage and the crystal mass (9, 11) is fed to the subsequent stage or out of the final stage into the washing column (20) for the complete separation of the mother liquor, the liquid depleted of isomer to be crystallized (21) being channelled out of the respective stage and the initial compound mixture (6a, 6b) being passed behind the final crystallization stage. The method is characterized in that at least some of the mother liquor of the crystal mass extracted from the final crystallization stage is gradually replaced by the initial compound mixture.

CANCEL CONSTRUCTION BACKGROUND OF THE INVENTION The present invention is concerned with a free-standing cancel (partition, partition or partition) construction and more particularly concerns the cancel frames configured for in-line connection, off-module connection and / or stacked connection. The panels of the partition (partition, partition or screen) to subdivide construction space are well known in the companies of office furniture and furniture of buildings. However, most known canceling systems have "module" cancel frames or frames that are only interconnected at their vertical side edges, so that they are not as flexible as desired. For example, "on-module" type cancel frames are not flexibly reconfigurable to selectively form increasingly smaller office arrays. Some known cancel systems have cancelles that can be attached to a main line of cancel panels in an "out of the module" array. The term "outside the module" is used herein to denote a first cancel panel that is joined at an angle to a second cancel panel, wherein one edge of the first cancel panel is spliced with the second panel at a site. which is between the vertical side edges REF. : 30261 \ of the second panel. However, the "outside the module" cancel panels use rails or rails to provide their capacity outside the module, where the "outside the module" panels are infinitely slidable adjustable along the rail. This means that the location of the panels outside the module must be carefully and accurately measured during the installation in order to result in office sizes that are actually of the same size. This can be a grievance during installation since any inaccurate measurement in rail type cancel systems outside the module results in a stack of inaccuracies, which can cause alignment problems where the systems "reconnect" to themselves . For example, inaccurate measurements can lead to misalignment, when a series of walls or walls form all four sides of an office, after which the last wall sections do not line up. Another problem with rails is that they have a poor aggregate appearance if they are added to an exterior of a cancel panel. Still, the rails incorporated in a frame or cancel frame are significantly added to the cost of the frame, particularly if the rail is extruded. Another problem with the rails is that they usually include a pair of opposed flanges defining between them a long access slot. The ridges must be held in a manner that does not interfere with the long access slot, such that the rails are frequently reinforced in terms of strength, to add undesirably to their weight and cost. In addition to the problems of the existing systems with respect to the connection outside the module, a further improvement in maximizing the service management capabilities of the freestanding cancel panels is also desirable, while at the same time minimizing the amount of material used to build the cancel panels. In particular, cancel frame constructions that allow flexible vertical and horizontal channeling of services, as well as wiring and other services, are desired. Barrier frame constructions that take maximum advantage of manufacturing processes and high volume / low cost assembly techniques, such as lamination and butt welding of the frame elements, are also desirable. Barrier frames that optimally distribute the stresses are desirable, but they provide an efficient combination of strength, structural integrity and manufacturing capacity, as long as they maintain functionality. In addition, frame constructions are desirable that provide easy and secure interconnection and / or reconfiguration at the site, which include arrays that are in-line, out of the module, stacked and incrementally adjustable. Thus, a cancel construction is desired that solves the aforementioned problems and has the indicated advantages.

BRIEF DESCRIPTION OF THE INVENTION The present invention includes an independent or freestanding canceling system for subdividing a construction space. The cancel system includes a frame or cancel frame having horizontally spaced uprights and horizontal frame or frame elements joining the uprights. A top element of the horizontal frame elements is attached to an upper part of the uprights. The struts include opposite sides defining a first distance therebetween and the upper horizontal frame member, • includes opposed structural side walls that are spaced apart a second distance substantially greater than the first distance. The upper horizontal frame member or frame further includes outwardly angled side walls attached to the uprights and structural side walls to structurally support the side walls such that the furniture components can be supported on the side walls. At least one cover panel is configured to releasably engage with the horizontal frame elements, in which the upper horizontal frame member or frame is included, such that at least one cover panel, when at cancel frame defines an internal cavity in the frame that extends horizontally over the entire width of the frame that encircles the uprights and that extends substantially vertically over the entire height of the frame to a lower part of the upper horizontal frame member . This allows the services to be arranged in the internal cavity and flexibly routed vertically and horizontally within the cancel frame and from the internal cavity of the cancel frame to an internal cavity of an adjacent / identical cancel frame. A furniture component is attached to at least one of the side walls and structurally supported by the upper horizontal frame member. These and other features and advantages of the present invention will be better understood and appreciated by those of ordinary skill in the art by reference to the following specification, the appended claims and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT For purposes of description herein the terms "upper", "lower", "right", "left", "posterior", "frontal", "vertical", "horizontal" and derivatives of the same are concerned with the invention as it is oriented with the front part of the cancel frame located adjacent to a worker standing in front of the cancel frame. However, it will be understood that the invention may assume several alternative orientations, except where expressly specified otherwise.

It will also be understood that the specific devices and processes illustrated in the accompanying drawings and described in the following specification are simply exemplary embodiments of the concepts of the invention defined in the appended claims. Hence, the specific dimensions and other physical characteristics concerning the modalities described herein are not to be considered limiting unless the claims expressly state otherwise. A furniture system (Figure 1) that implements the present invention includes a plurality of interconnectable systems, such as the systems described in the applications identified above. The furniture system 40 further includes a freestanding or freestanding cancel panel system 41 comprising 10.2 cm (four inch) wide cancel panels 42 (referred to herein as "WALL ZONE") and panels 43 5.1 cm (two inches wide) (in this so-called "WALL ZONE" or "WALL WALL") cancel panels. The cancel panels 42 and 43 include a plurality of pre-assembled frames of different height and width, such as the base cancel frames 44 (Fig. 2) and 45 (Fig. 22), respectively and the stacker gate frames 120 (Fig. 15) described below. A plurality of cover panels 73 of different size and type (Figure 1) can be attached to the cancel frames to aesthetically cover the sides thereof. Barrier frames 44, 45 and 120 are interconnectable in a myriad of different plane arrangements. Notably, in each of the plane arrangements, the cancel panels are easily interconnectable in discrete locations or locations to form office spaces sized exactly of a selectable size without the need to carefully / accurately measure with a measuring or ordering tape. order new parts. This feature, in combination with the highly flexible and accurate interconnection systems, makes the present system 41 of self-supporting cancel panel very functional, remarkably accurate and also highly flexible / re-configurable in a wide variety of arrangements. The interchangeability and readjustment capacity reduces the need to order or order a substantial number of new components when the office plan is reconfigured. Also, the main components of each of the cancel frames 44 and 45 are manufactured by rolling, so that their cost, when they are produced at high volumes, is generally very competitive and its accuracy and consistency in cross section much better than for frame components made by stamping process.

The 10.2 cm (4 inch) base canceling frames 44 (Figures 2-4) include at least two stanchions 46 spaced apart. A plurality of horizontal frame members 47-51 are attached to the uprights 46 at predetermined heights, as described hereinafter. Frame members 47-51 have front and rear faces spaced approximately 3 inches apart. The panel 42 becomes a 9.6 cm (3.8 inch) thick panel after the joining of the deck panels 73 and 10.2 cm (4 inches) after the joining of the lining components. The levelers 52 are operatively attached to the lower parts of the uprights 46 and are configured to be releasably secured to the floor channel 53 (Figure 40). The cancel frames 44 are provided in a variety of different heights and lengths in order to meet the demands of the customer concerning the functional and aesthetic considerations in a modern office or construction area. Notably, the base cancel frames can be constructed with all the horizontal frame elements 47-51 above or with only selected elements of the horizontal frame elements, such as with only one frame element 47, 48 and 51 (see FIG. 15). ).

The external uprights 46 (Figures 2-3) have rectangular cross sections. Intermediate uprights 55 are required when the horizontal distance between the uprights 46 reaches a relatively wide separation distance. The separation distance at which intermediate posts are required depends on the functional requirements of the frame system and also on the thickness of the material and the inherent strength of the cancel frames. For example, intermediate uprights may be desirable as long as the spacing between the adjacent uprights reaches a distance greater than about 61 cm (two feet) if the cancel frame must support furniture components. Notably, the intermediate part (s) may be rectangular or alternatively as shown in Figures 2-4, may have a square cross section. The uprights 46 (and 55) extend continuously from top to bottom of the cancel frames 44. The upper end 56 (FIG. 5) of the uprights is butt welded / welded under an inert gas atmosphere to a lower part of the upper frame member 47 and lower end 57 (figure 12) of the uprights is butt welded / inert gas welded between the pair of lower frame elements 51. This provides a rigid but open frame. It also facilitates accurate and efficient fabrication since the horizontal frame members and elements 47 and 51 can be repaired exactly with the welding material which compensates for any dimensional variation in the length of the posts. A hexagonal nut 58 is welded to an inner side of the lower end 57 of each of the uprights 46. A lower portion of the hexagonal nut 58 extends slightly below the lower frame member 51 and a threaded rod 59 (FIG. 12) it extends threadably through the nut 58. The release rod 59 includes a shaped end 60 formed to engage correspondingly with the small end of a key opening 61 (FIG. 39) in a hat section 62 a channel 63 of the floor. A fastener 64 secures the leveling rod 59 at the small end such that the leveling rod 59 is securely attached to the floor channel. When required by the codes, floor channel 62 is secured in place by nailing, adhering or otherwise fastened to a bottom flange of channel 62 from the floor to a building floor, such that interconnected mounting of the frame 44 of cancel and channel 62 of the floor is resistant to damage / failure due to a catastrophic event, such as an earthquake. The upper horizontal frame member 47 (Figure 6) is tubular and laminated to provide a cost-efficient manufacturing process. The upper frame member 47 includes a channel-forming upper section 65, opposite perforated side wall sections 66, attached to the edges of the upper channel section 65 and a U-shaped support section 67 for holding the sections 66 of opposite side wall.

More specifically, the upper channel section 65 includes a central flange 68 with openings 80 to allow stacked connection and openings 80 'to allow channeling of wires therethrough. The flanges 69 opposed vertical internals extend from the central flange 68 and the horizontal upper flanges 70 extend outward from the central flange 68. The internal * flanges 69 are combined with the central flange 68 to define an open upward channel or conduit 71 adapted for receive wires laid from above. The side wall sections 66 extend vertically downward from the shoulders 70 and include attachment openings 72 of the fastener supporting the cover panel (Figure 5) to releasably receive the fastener connectors of the cover panel (see , figure 44). The cover panels 73 (figures 1 and 41) comprise relatively flat panels adapted to cover the cancel frames for aesthetic purposes. The cover panels can be manufactured from sheet metal, plastic, composite / particulate materials, other semi-solid or structural materials, or combinations thereof. The openings 72 that hold the cover panel (Figure 5) are presented in pairs that are separated by approximately 5.1 cm - 7.6 cm (2 to 3 inches) "DI", preferably 6.9 cm (2.7 inches), the pairs are spaced apart regulate horizontally by approximately every 15.2 cm (6 inches) "D2" along the section 66 of the side wall. A row of connecting slots 74 receiving the hook that is held in the furniture component extends horizontally along the side wall sections 66 just above the openings 72. The slots 74 that hold the component are adapted to receiving horizontally the hooks oriented in brackets to join the furniture components to the horizontal frame element 47, such as cancel frames attached outside the module, collecting trays, shelves and the like. The side wall sections 66 are spaced out from the sides of the uprights 46 such that a cavity is formed between an inner surface of the panels 73 and the uprights 46 as discussed hereinafter. The U-shaped support section 67 (Figure 6) of the upper frame member 47 includes a flat lower flange 75 and oppositely angled side flanges 76 extending upwardly to approximately 60 degrees. The angular side rims 76 support the side wall sections 66 at a spaced-out site from the sides of the uprights 46 (and 55), such that the roof panels 73 are spaced from the uprights 46 and 55 to create an internal cavity 73 '. This cavity 73 'is remarkably open and provides an open interior space well adapted to receive a high density of services. The services may be flexibly routed to substantially anywhere within the frame 42 or adjacent frames and may include bundled wires or conduit covered wires of approximately 2.5 cm (1 inch) in diameter. The angled flanges 76 provide a strut-like support for supporting the side wall sections 66, with an optimal stress distribution. Thus, in combination with the tubular shape of the upper horizontal frame member 47 allows the sheet material forming the upper tubular horizontal frame member 47 to be optimized to a relatively thin gauge. The lower and upper / middle flanges 68 and 75 include square openings 80 and rectangular openings 80 'for channeling the wire therethrough. The uprights 46 are welded to the lower flange 75 of the support section 67. The fact that the upper horizontal frame member 47 is tubular and also the fact that it includes angled side flanges 76, together with its other flat flanges joined by convoluted bends, causes the upper frame member 47 to be particularly strong and structurally rigid. This allows the upper frame member 47 to carry substantial weight such as collecting trays, shelves and other hanging furniture. The inherent strength of the tubular upper frame member 47 also reinforces the entire frame 44 against unwanted torsion and torsional deflection. As an example of the strength of the tubular frame member 47 and its contribution to the strength or strength of the frame 44, it is contemplated that the aforementioned tubular upper horizontal frame member 47 can be fabricated in a thickness of 18 gauge (ie, approximately 0.122 cm to 0.127 cm (0.048 to 0.050 inches) thick) and still sustainably / stably supporting a weight of 181 kg (400 pounds) cantilevered to several inches in front of the center of the frame member 47, with the frame member 47 held at its ends and separated approximately 122 cm (48 inches) or more. The 181 kg (400 lb.) support is provided without an objectionable amount of torsional or transverse deflection of the tubular upper horizontal frame member 47 (based on conservative standards for load carrying, freestanding cancel panels). This contrasts with conventional self-stable cancel panels constructed to carry weight that are normally manufactured in a 16 gauge thickness (ie, approximately 0.1524 cm (0.060 inches) thick) in order to meet similar loading / deflection standards. The fact that the upper horizontal tubular frame member 47 includes perforated side walls 66 with sheet metal material extending from its upper part to its lower part, and the fact that the upper horizontal frame member 47 does not include a frame of excessively long access, (as is characteristic of the stringers or rails, as discussed in the background of this description) results in the upper horizontal frame member 47 being particularly strong. A platform bracket or bracket 77 (Figure 6) is optionally welded to the underside of the central flange 68 of the upper channel section 65 to the interior of the tubular upper horizontal frame member 47. The bracket or bracket 77 includes reinforcing ridges 78 on at least the side of each end and further includes an extruded hole 79 which is aligned with a hole 80"in the central flange 68. The extruded hole 79 is located at a short distance (eg, about 2.5 cm (about one inch)) from the end of the central flange 68. The bracket 77 or bracket reinforces the central flange 68. The extruded hole 79 is threadably engaged with a screw 144 (FIG. 30) to provide the in-line connection (Figures 27-30) and the out-of-module connection (Figures 32-35) of the cancel frames, as described later herein The pair of vertically aligned square holes 80 (Figure 38) they are located in the central flange 68 and the lower flange 75 near the ends thereof at a location in the interior but vertically close to the ends of the uprights 46. The holes 80 are configured to receive close A tubular stacking bracket or cantilever 170 (see FIGS. 29 and 38) is attached to the inner side of a vertical part 46 of the base frame 44 and is an internal side of a vertical piece 121 of a frame 120 stacker, as discussed in FIG. later in the present. The horizontal frame members 49 at waist height (Figures 7-8) include two rectangular tubes welded in an inert gas atmosphere on opposite sides of the uprights 46 and 55. Each of the frame elements 49 includes a face outer flat 82 defining row of openings 83 holding the panel cover close to the top of the frame members 49 to releasably receive the cover panel fastener connectors. Similarly with the previous openings 72, the openings 83 that hold the cover panel are presented in pairs spaced by approximately 5.1 cm (2 inches) and the pairs are spaced regularly horizontally for about every 15.2 cm (6 inches) along the outer flat face 82. A row of slots 84 receiving the hook that holds the furniture component extends horizontally along the faces 82 just above the openings 83 that support the front cover panel. The slots 84 holding the component are adapted to receive horizontally oriented hooks on the brackets or brackets (for example, the brackets or brackets 150, figure 33, or the bracket 160, figure 37) to join the furniture components to the elements 49. of horizontal frameworks, such as cancel frames attached outside the module, collecting trays, shelves and the like. The grooves 84 'that support the particular component, located above the openings 83 that support the front cover panel, include a vertically extending notch 85 that can be used to access the interior of the frame member 49. Another row of receiving apertures 86 of the fastener supporting the cover panel and another row of slits 87 that support the component extend horizontally along a lower portion of the frame elements 49. The configuration of the openings / slots 86 and 87 are identical to the configuration of the openings / slots 83 and 84 and are vertically aligned therewith. The arrangement of the openings / slits allows the cover panels 73 to be attached to the frame 44 in different arrangements. Several such cover panel arrangements are shown in Figure 1. For example, a single cover panel can be attached in such a manner as to completely cover the frame 44 from top to bottom. If an intermediate fastener is necessary to retain the cover panel to the frame 44, then it is positioned to engage with one of the openings 83 or 86. Alternatively, a partial height top cover panel may be attached to the frame 44, with its edge or lower edge located just above the lower grooves 87. For example, in the partial height arrangement, the joint fasteners on the upper partial height cover panel engage with the notches 85. Then, one joins a lower partial height cover panel having an upper edge located just below the slits 87 that hold the lower component. This leaves the grooves 87 holding the lower component continuously exposed with the upper and lower cover panels on the frame 44. Thus, the furniture components can be attached to or removed from the frame 44 without disturbing the cover panels 73. In still another alternative (see Figure 3, the covers shown in dashed lines), a partial height upper cover panel 73 has a lower edge that is located above the grooves 84 that hold the upper component and a lower cover panel Partial height has an upper edge that is located below the slots 87 that hold the lower component. A short height concave band panel cover 73 'of approximately 7.6 cm (3 inches) in height or approximately is joined between the grooves 83 that hold the cover panel and the notches 88, to expose the slots 84 and 87 that They hold the component. In such an arrangement, the furniture components may be attached to one or both of the slots 84 and 87, still while the concave 7.6 cm (3 inch) cover panel is still attached. This double adjustment of grooves 84 and 87 supporting the component is particularly advantageous for use to support corbels or cantilevered brackets 200A that hold the shelf and shelves 200B (Figure 3) in front of the horizontal frame member 49. Notably, a fifth row of openings 89 are located longitudinally along a central line of the face 82 at intervals spaced apart by 15.2 cm (6 inches). These openings 89 are engaged by spring clips on the panel cover at waist level to retain the waist level cover on the frame 44. When installed, the outer surface of the waist height cover it is flush with the panels of the cover 73 or it can be recessed or recessed therefrom. Even with the cover panels 73 attached, the slots that hold the furniture component (e.g., slots 72 and 84) can be accessed by brackets or hooked brackets to support the trays 200C (Figure 3) or the like. The horizontal frame elements 50 at knee height (Figures 9-10) comprise a pair of C-shaped channels facing inward, welded on opposite sides of the uprights 46 (and 55). A reinforcing rib 50 'is optionally formed in the C-shaped channel if necessary. In yet another alternative, a bracket or bracket is welded or secured to the uprights 46 having legs that extend outwardly and the C-shaped channels are hooked onto bracket legs or brackets. In still a third alternative, the frame element 50 is a single rectangular tube very similar to the tube 48 of figure 11 described below. Regardless of its particular cross-sectional shape it is contemplated that the frame elements 50 will have a configuration of openings 90 that support the cover panel and grooves 91 that hold the component forming an identical configuration to the openings 83 that hold the panel cover and slots 84 that support the component on the horizontal frame member 49 at waist height. The purpose and function of the openings 90 that support the cover panel and the grooves 91 that support the component are identical to the openings 83 that support the cover panel and the grooves 84 that support the component. The horizontal frame element 48 at shoulder height (Figure 11) is used where the uprights are so long that the upper horizontal frame member 47 is significantly separated above the horizontal frame member 49 at waist height . The horizontal frame element 48 at shoulder height is also desirable where an intermediate support for the furniture components is desired.

The frame member 48 is a rectangular tube having opposite perforated flat side faces 96 and 97 that are identical to the outer faces of the horizontal frame elements 50 at knee height. However, the horizontal frame member 48 is rectangular and includes upper and lower horizontal transverse ribs 98 and 99 that extend from front to rear of the frame 44 and interconnect the vertical faces 96 and 97. The upper and lower horizontal flanges 98 and 99 they are cut to form openings at their ends and middle part to receive engably and engage the uprights 46 and 55. It will be noted that the lower flange 99 may comprise two separate and unconnected flange sections ending in internal edges that are spliced to the outer sides of the uprights 46 and 55. Also, the upper rim 98 may include a double back reinforcing rib 98 ', formed to be disposed adjacent an edge of the uprights 46 and 55. The upper and lower rims 98 and 99 are soldiers of the inert atmosphere or otherwise securely joined to the uprights 46 and 55. The horizontal frame elements 51 adjoin The floor struts (Figures 12-13) are opposite Z-shaped elements, having an internal flange 100 for engaging the uprights 46 and 55. The side flanges 102 extend horizontally from the inner side rims 101 and the vertical side rims. 103 extend vertically within the side flanges 102. The horizontal frame member 51 adjacent the floor may include openings that support the cover panel and grooves or slots that hold the component similar / identical to the openings 83 that support the panel. cover and slots 84 that hold the component, if desired (see Figure 7). In the illustrated embodiment the lower edge of the vertical side flanges 103 is constructed to engage the fasteners 184 of the lower cover panel connector to retain a lower edge of the cover panels 73 attached to the bottom of the frame. A channel 63 of the exemplary floor is shown by holding a 5.1 cm (two inch) cancel frame 45 in Figures 22 and 39-40. A similar floor channel can be constructed to be coupled with a four-inch (10.2 cm) cancel frame. The floor channel 63 (Figure 39) includes a central section with a raised central rim 62, internal side rims 108 and a lower rim 108 '. The ridges 109 extend horizontally outwardly from the inner side rims 108 and the independent external rims 110 extend upwardly from the edges of the rims 109 which engage with the floor. The outer flanges 110 include grooves 112 that hold the component to receive brackets or brackets of the furniture component. Also, the upper edge 113 of the outer flange 110 is adapted to releasably receive friction / insertion connectors 114 on a cover plate 115 similar to a rain guard. It will be noted that the present floor channel joining system can be used in a variety of different floor channel configurations, which include those that have a relatively flat and wide floor-engaging flange that extends completely from a front to a back part of the floor channel. The openings that receive the component of the horizontal frame elements 47-51 are strategically positioned to reflect a predetermined vertical dimensional logic. In addition, the horizontal frame elements 48-51 are installed in relation to the upper flat surface of the upper frame member 47 and are located exactly in relation to the openings 72/74 in such a way that the vertical dimensional separation of all the openings in the frame elements 47-51 is exactly controlled. Notably, this arrangement allows the lengths of the uprights 46 to vary without adversely affecting the location of the various openings.

Specifically, as shown in Figure 2, the openings are located in such a way that there is a dimension of approximately 30.5 cm - 33 cm (12 to 13 inches), between the openings in Site A and Site B, between the site B and site C and between site D and site E. Also, the distance between site E and site F in illustrated frame 44 is twice the dimension between sites A and B. This allows a panel of cover "IX" that has a dimension equal to distance AB is used to cover any of the spaces or separations of sites AB, BC or DE. A "2X" or double height roof panel can be used to cover spaces or distances from the A-C or E-F sites. A cover panel "IX plus" can be used to join the B-D sites or the C-E sites. A "2X plus" cover panel can be used to join the A-D sites or the B-E sites. Notably, the overall height of the cancel frames 44 can be varied. In such a case, it is advantageous to design the upper frame element 47 in such a way that it is at a height which is above the horizontal frame element following the upper one by a distance equal to the distance BC or by the distance BD or some multiple. / logical variation of it. This advantageously allows a relatively limited number of cover panels to cover all the different cancel frame constructions while still having the possibility of obtaining ergonomically correct space division heights desired. Thus, this scheme greatly reduces the handling or administration of inventory in the factory and on the site, simplifies orders and packaging and also simplifies manufacturing extensively, particularly since the cover panels can be covered with a myriad of different materials and / or different structural compositions. The cancel panels 42 also include a stacker cancel frame 120 (Figures 15-17) adapted to be stacked above the base cancel frames 44. The stacker cancel frame 120 includes uprights 121 identical to the uprights 46 of the base cancel frame 44 and further includes horizontal frame elements comparable to any of the horizontal frame elements on the base cancel frame 44. The particular horizontal frame elements of the stacker cancel frame 44 depend on the functional requirements of the stacker cancel frame 120 and also on its vertical height, length and other functional / size / spatial requirements. The illustrated stacker cancel frame 120 includes an upper horizontal frame member 122 structurally identical to the upper horizontal frame member 47 of the base cancel frame 44, an intermediate horizontal frame member 123 identical to the horizontal frame members 48 or 50 of the frame 44 of the base gate and a lower horizontal frame member 124 structurally identical to the lower horizontal frame members 51 of the base cancel frame 44. Notably, frame 120 stacker does not include a leveler. Instead, the stacker frame 120 includes downwardly extending legs or alignment locators 125 (FIGS. 18-19) welded or otherwise securely attached to the bottom portions of the horizontal frame member 124 of the frame 120 stacker . Specifically, the locators 125 include a plate 125A welded to a lower part of the lower horizontal frame member 123. A rounded J-shaped rim 125B is formed in a lower part of the plate 125A, the rim 125B has a long width dimension that extends transversely from a front part to a rear part of the stacker frame 120. The locator flange or leg 125B is adapted to fit correspondingly and extends through the channel 71 of the upper horizontal frame member 47 of the base cancel frame 44 when the frame stacker frame 120 is attached to the base cancel frame 44 (Figure 20). During assembly, the rounded lower edges 125C of the leg 125B engage with the internal sidewall flanges 69 and cause the stacker cancel frame 120 to be tilted to a centered position on the base cancel frame 44 as the cancel frame 120 Stacker is installed in frame 44 of cancel base. As the locators 125 fully settle to the channel 71, the opposing fins 125D engage with the upper portion of the flanges 70 of the upper frame member 47. After this, a stacking bracket or bracket 170 (figures 29 and 38) is secured / bolted to the internal sides of the aligned spliced uprights 46 and 121 of the base and stacker cancel frames 44 and 120, respectively. The brackets or stacking brackets 170 keep the frame 120 of the stacker securely mounted rigidly on the base frame 44. The modified 5.1 cm (two inch) cancel panel 43 shown in Figure 1 (which becomes a 5.1 cm ("two inch") only after joining the cover panels) includes a cancel frame. 45 (Figures 21-23) having similar posts 131 of the uprights 46 of the zone wall cancel frame 44. However, the horizontal frame elements 132-136 have a narrow width that only exceeds the width of the uprights 131 by two thicknesses of sheet metal, one thickness is on each side of the uprights 131, at the site 131 'for example . Thus, the cancel panel 43 formed by the joining of the cover panels 46 to the sides of the cancel frame 45 is only 5.1 cm (two inches) in total width. Notably, the same cover panel 73 can be attached to the 5.1 cm (two inch) frame 45 as it is adapted to be attached to the 44 cm (four inches) frame 44. The upper horizontal frame element 132 includes a rectangular tubular element 137 and a U-shaped channel 138 welded to the tubular element 137. The lower horizontal frame element 136 similarly includes a rectangular tubular element 139. A U-shaped channel (not shown) similar to the U-shaped channel 138 may be welded to the bottom of the tubular member 139 if desired. The intermediate horizontal frame members 133-134 each comprise opposing hat-shaped channels that have notches cut to receive the uprights 131. The legs 133A and 134A of the opposite channels of the hat-shaped channels are spliced and they are welded together and the uprights 131. The openings that receive the connector to hold the cover panels 73 and also the slots that receive the hooks to receive hooked brackets to hold furniture components are formed on the sides of the horizontal frame elements 132 -134 and 136. It is contemplated that a configuration of openings / slots similar to those found in the cancel frames 44 will be formed in the frames 45, although various aperture configurations / slots are possible. Normally, the horizontal frame elements of the cancel frame 45 are aligned horizontally with the horizontal frame elements of the cancel frame 43, although this is not absolutely necessary either. It is contemplated that a 5.1 cm (two inch) wide stacking frame can also be constructed if desired. The 5.1 cm (two inches) wide stacking frame contemplated is very similar to the 5.1 cm (two inch) wide base canceling frame 45, but includes holes adapted to receive a stacking connector similar to a roller or rod to the connector 170 of stacking. An in-line connector 140 (Figures 24-26) is adapted to interconnect aligned and adjacent 10.2 cm (four inches) cancel frames 44. The inline connector 140 includes a pair of legs 141 spaced apart by a slot 142 and joined together at one end by a planar section 143. The slot 142 has a width that is less than the axis of a connector pin 144 used to securely fasten. secure the inline connector 140 to a cancel 44 frame. However, three expanded receptacles or cavities 145-147 are formed along the slot 142 to receive the shaft of the connecting pin 144, for reasons that are described later herein. The receptacle 145 is formed in a base of the groove 142. The receptacle 146 is formed approximately halfway along the groove 142 but spaced apart therefrom. The outer receptacle 147 is formed approximately halfway between the open end of the slot 142 and its mid-point. The open end 148 of the groove 142 is angularly outward to create a mouth. Reinforcing ribs 149 are formed along the outer sides of the legs 141 to reinforce the legs. The flat section 143 has a width approximately equal to the outer edge of the legs 141, and which is approximately equal, but slightly less than the width of the channel 71 in the upper frame member 47. Two or more inline connectors 140 (FIGS. 27-30) are used to connect a pair of base cancel frames 44 as follows. At the level of the floor (Figure 27), an inline connector 140 is inverted in such a way that the reinforcing ribs 149 are mounted on both sides of the raised central rim 107 of the floor channel 63. The inline connector 140 is moved in such a manner that the receptacles 145 and 146 (Figure 28) align with the extruded holes in the raised central flanges 107 of the adjacent floor channels 63. Autoderivable screws 144 extend to the extruded holes in the adjacent floor channels 63. The axes of the screws 144 are sufficiently large such that the in-line connector 140 can not be removed even if the screws 144 are loosened. However, the screws 144 hold the inline connector 140 securely as well. Remarkably, the in-line connector 140 can be stored in a floor channel 63 by removing the screws 144, by retracting the inline connector completely on the floor channel 63 and thereafter by extending the screw 144 through the end receptacle 147. This locates the inline connector 140 in a storage position where it is located completely within the footprint of the end of the floor channel 63 at a convenient location for later use. A second inline connector 140 (FIG. 29) is located on the central rim 68 of the upper horizontal frame member 47 (below the central rim of the lower horizontal frame member 51). The reinforcing ribs 149 of this second inline connector 140 are positioned between the vertical internal flanges 69. The second inline connector 140 is moved in such a manner that the receptacles 145 and 146 align with the extruded holes in the central flange 68 of the recesses. adjacent base frame 44 frames. Self-derinding screws 144 extend to the extruded holes. The axes of the screws 144 are sufficiently large such that the inline connector 140 can not be removed even if the screws 144 is loosened. However, the screws 144 hold the connector 140 in line securely as well. Remarkably, the in-line connector 140 can be stored in a base cancel frame 44 by removing the screws 144, by retracting the in-line connector back to the base cancel frame 44 and thereafter by extending the screw 144. through the end receptacle 147. This locates the inline connector in a storage position where it is located completely within the footprint of the end of the base cancel frame 44. When stacker gate frames 120 are used an additional inline connector 140 is attached in the upper horizontal frame member 122 in a manner identical to the manner described for the element 47 of the upper horizontal frame of the base cancel frame 44. Advantageously, cancel frames 44 and 45 (and including associated stacker frames) can be joined together in a variety of arrays outside the module, which include fin wall to fin wall (figure 31), wall fin to wall area (figure 1), wall area to wall area (figure 33) and wall connections area to fin wall. For this purpose, two different connectors 150 (FIGS. 32-35) and 151 (FIGS. 36-37) are provided outside the module, each is adapted with hooks at one end to engage with the slots in the cancel frames and are adapted at its other ends to engage with one end of a cancel frame 44 or 45. The connector 150 outside the module (Figures 32-35) is constructed to join a 10.2 cm "zone wall" cancel frame 44 (four inches) to another such frame 44 'of cancel (figure 33). The connector 150 outside the module (figure 32) includes a pair of Z-shaped plates 152 and 153 slidably secured together by a rivet 154. A plate 152 includes a pair of hooks 155 oriented laterally / horizontally in a first direction and the other plate 153 includes a second pair of hooks 156 oriented laterally / horizontally in a second direction opposite to the first direction. The hooks 155 and 156 are configured to overlap to define a narrow dimension D3 when the plates 152 and 153 are moved aside to a released position (figure 34). In the released position, the hooks 155 and 156 are folded and can be inserted into the slots that hold the furniture component in the direction A, such as the slots 84. When they are displaced in a direction opposite to an interlocked / coupled position ( 35), the hooks 155 and 156 are dispersed to a dimension D4 and securely engage with the material forming the grooves or grooves that hold the furniture component. The grooves or grooves 157 and 158 are located at the end of the plates 152 and 153 opposite the hooks 155 and 156. These grooves 157 and 158 are aligned when the plates 152 and 153 are slid to the interlocked / engaged position. The slots 157 and 158 include an enlarged end that forms a receptacle 159 for receiving and capturing / retaining an axis of a screw 144. As previously described, the screw 144 engages an extruded hole in the cancel frame 44. The Z-shape of the connector 150 is configured to position the slotted end of the plates 152 and 153 at a height adjacent the extruded hole on the frame 44 with which the screw 144 engages (Figure 33). Tabs 152A and 153A are provided on the edges of the plates 152 and 153 to facilitate unlocking and securing the plates 152 and 153. A second connector 160 outside the module (Figures 36-37) is used for the interconnection outside the module of the fin wall cancel frames.

Briefly, the connector 160 outside the module includes a pair of legs 161 joined together resiliently by a resiliently resilient ring end 162. The legs 161 have opposing hooks 163 at their free ends adapted to engage the slots or slots that hold the movable component in the frames 44 or 45. The legs 161 are formed in a Z-configuration to locate the end 162 of the spring at a predetermined height relative to the grooves in the frames 44 or 45, such that the end 162 is positioned adjacent an extruded hole and screw 144. A slot or slit is defined between the legs 161, which includes an enlarged region defining a receptacle 164 for receiving the axis of the screw 144. When the axis of the screw 144 is located in the receptacle 164, the shaft is captured and further the legs 161 are forcefully separated to securely engage the slots at the non-releasable they are united. Similar to the four-inch 10.2 cm cancel frame 44, two or more of the connectors 160 outside the module will normally be used to secure a fin wall cancel frame 45 to a main / center frame, one in one upper part and one in a lower part of the frame 45. A tongue 164A extends from the ring end 162 to engage in detail on the frame 45 to maintain the connector 160 in longitudinal alignment with the horizontal element to which it is attached.

The stacker connector 170 (Figures 29 and 38) is used to securely attach a stacker frame such as stacker frame 120 to a base cancel frame 44. The stacker connector 170 is a tube having a square cross section. Two spaced-apart separation holes 171 and two spaced apart spacing slots 171 'are formed in connector 170, two at each end. The two slots 171 'in the bottom align with the holes in the upper part of the vertical part 46 of the base cancel frame 44 and the holes 171 in the upper part align with the holes in the lower part of the vertical part 121 of frame 120 of cancel stacker. The bolts 172 extend through the holes for attaching the stacker connector 170 to the respective uprights 46 and 121. The cover panel 73 (Figure 41) includes a large flat panel 180 fabricated from any of a variety of different materials., such as sheet metal, plastic, particulate materials, composite materials and combinations thereof. The illustrated cover panel 73 includes edges or ribs 181A-181D of sheet metal, laminated to protect, form and reinforce the marginal edges of the flat panel 180. The ribs 181A-181D are configured along their perimeter to receively engage and holding the connectors or receivers 183, resilient upper ones holding the cover panel and the resilient bottom connectors or fasteners 184 that hold the cover panel. Three such upper and lower fasteners 183 and 184 are shown in Figure 41, although more or less may be added as necessary for functional reasons. Additional fasteners 184 may also be added along the vertical side edges 181B and 181D of the cover panel 73, such as where the cover panel extends a significant vertical distance and where it is desirable to retain the middle part of the cover panel. cover to the frame. The flat panel 180 (figure 44) includes a rear flange 188 to which the ribs 181A-181D are spot welded or otherwise secured. The upper ribs 181A consist of a laminated portion having a vertical flange which engages the panel 189. A flange 190 of the upper edge extends forwardly from an upper part of the vertical flange 189 and a flange 191 of double rear covers the flange 189 of the upper edge. A second vertical flange 192 extends upwardly from a lower edge of the flange 189 that engages the panel. The lower portion 193 of the second vertical flange 192 is walled against and engages with the first vertical flange 189 to reinforce it. An upper portion 194 of the second vertical flange 192 extends upward but is displaced therefrom to create a space 195. The cross section of the ribs 181B-181D are identical to the cross section of the ribs 181A. It will be noted that the ribs 181B and 181D can be cut at the ends to eliminate interference. Alteratively, flanges 189 and 192 on adjacent corner pieces may be cut such that flanges 189 and 192 overlap. For example, the ridge 189 could be cut briefly and the flange 192 left lengthwise on the rib 181A and the flange 192 cut short and the flange 189 left long on the ribs 181B, such that the rim 192 of the ribs 181A overlap with the flange 189 of the ribs 181B. The upper connector or fastener 183 holding the cover panel (Figure 45) includes a lower section 196 that engages with the cover panel, U-shaped and a U-shaped section 197, which engages with the frame . The lower section 196 includes opposite flanges 198 and 199 with a space therebetween 200 to engage frictionally with the flanges 189 and 192 in the ribs 181A. the flange 199 is formed to engage correspondingly with the flange 192 of the ribs 181A. A tooth 201 on the flange 198 engages the flange 189 and a second tooth 201A on the flange 199 engages the curvature 194 'on the flange 192 of the ribs 181A to prevent accidental disengagement or misalignment. The rear flange 188 of the body panel is slotted to receive the fastening flange 198 in such a manner that it locates the fastener 183 on the cover panel 73. The upper section 197 of the fastener includes a flat horizontal bottom flange 202, a section 203 of the resilient end and an inverted curved corner shoulder 204. An interlocking anti-disengagement tooth (or teeth) 205 extends from the angled flange 204, the tooth 205 is co-planar with the angled flange 204. An unlocking / unlocking tab 206 also extends from the angled flange 204. The tongue 206 extends at an angle below the tooth 205. The tongue 206 extends through a plane defined by the vertical flange 194 (figure 47) to a site within the space 200. The tooth 205 does not extend through the plane defined by the vertical flange 194, such that the fastener 183 can be inserted into the frame member 48 to engage with the tooth 205 with an inner surface 207 of the horizontal frame member. A flexible lining strip or "worm" 209 (FIG. 47) includes a link leg 210 that fits into the space 200 in the ribs 181A. The leg 210 may include a hook or extension (see strips 209A in Figure 47A) or may include a lower J-shaped portion 209B '(see strips 209B in Figure 47B) to provide secure retention or it may be gummed in its place if desired. An upper section 211 of the strip 209 is U-shaped and flexible with a hardness of approximately 88 according to the tests of ASTM D2240-75, in such a way as to compensate for the space between the vertically adjacent roof panels 73. The upper section 211 extends to aesthetically fill the space between the cover panels 73 and to hide the grooves that hold the furniture component (such as the grooves 84). However, upper section 211 is resiliently compressible to allow access behind strips 209 and slots when desired (see Figure 48). Also, upper section 211 is flexed around any brackets attached to slots (84). The joint leg 210 is stiffer than the upper section 211, with a hardness of approximately 80 according to the tests of ASTM D2240-75. It is also notched to receive the tab 206 on the fastener 183 and to allow vertical operative movement of the tab 206. It is contemplated that the lining strip 209 can be co-extruded from two materials of different hardness to obtain the flexibility of the upper section 211 and rigidity of the leg 210 desired. By urging the tab 206 downward with a tool such as the tool 220, the section 203 of the resilient end of the fastener 183 flexes downward, to cause the anti-disengagement tooth 205 to move from a position engaged with the frame. raised interlock (figure 47) to a released frame / uncoupled position (figure 49). The connector or fastener 184 of the lower part that supports the cover panel (figure 46) includes an upper section 213 that engages with the U-shaped cover panel which is an inverted mirror image of the lower section 196 on the fastener 183. A lower section 214 that engages with the frame extends from a lower portion of the upper section 213. The lower section 214 includes a flat horizontal lower flange 215, a resilient end section 216 and an angular flange 217 toward top bent inversely. A downwardly angled flange extension 218 extends from the angled flange 217. The flange extension 218 engages frictionally with an upper edge of an opening or notch, such as the notch 85, in a horizontal frame member, such as the housing. frame element 49 (figure 7). Alternatively, the flange 218 is constructed to engage with a lower edge of the flange 103 on the lower horizontal frame member 51. The cover panel 73 can be attached to a pair of vertically spaced horizontal frame members, such as the illustrated frame member 48 and 49 (FIG. 47) by engaging the top fasteners 183 until the anti-strike teeth 205 engage with the upper frame element 48 (figure 47). Then, the lower fasteners 184 are inserted in engagement with the lower frame member 49. Notably, the frame elements 48 and 49 are used for illustrative purposes, but the fasteners may be coupled with any pair of frame members 46-51 or similarly vertically spaced horizontal frame members. When they are united, the opposite cover panels 73 define an internal cavity within the frame 44 which extends horizontally along the width of the cancel frame and substantially over the entire height of the frame. The wires can be arranged in the internal cavity and can be routed around the uprights between the uprights and an inner surface of the cover panels. Notably, the space between the external surface of the uprights and the inner surface of the cover panels is approximately 2.5 cm (1 inch) and substantially outside of the external surface of the vertical part, such that the wires covered by The conduit that are 1.9 cm (3/4 inch) or more can be easily channeled along and around the internal cavity. Since the uprights are approximately 2.5 cm (1 inch) thick, the internal cavity is approximately 7.6 cm (3 inches) in total thickness for a "10.2 cm (four inch)" canceling system 42 having a frame 44 of cancel. It is also contemplated that fasteners 183 and / or 184 can be used to join a cover panel to the vertical frame elements as well. For example, the cover panels incorporating the fasteners 183 and / or 184 could be attached to "Steelcase 9000 Series" cancel panels, which panels are well known in the industry. The anti-disengagement fastener 183 is particularly useful where the secure but releasable attachment of the cover panels is desired, such as to withstand the faults of a catastrophic event eg earthquakes). In order to remove the cover panel 73, it is necessary to release / uncouple the anti-disengagement tooth 205 from the upper fasteners 183. For this purpose, a tool 220 is provided (Figure 50). The tool 220 is basically a small knife or thin blade tool having a handle 221 and a sheet 222 of rigid, flat sheet metal. An end 223 of the sheet 222 is bent 90 degrees to form a flange. The required height of the end flange 223 depends on the dimensions of the cover panel 73 and the location of the top fasteners 183. It is contemplated that the height of the end flange 223 will be from approximately 1.27 cm (1/2 inch) to 1.9 cm. (3/4 of an inch). The tip of the end flange 223 can be angled / tapered inward from its edges to its center to create a ramp that facilitates its use, as described hereinafter. The tool 220 (Figure 48) can be manipulated on the garrison strip 209 into the space between the vertically adjacent cover panels 73, such that the end rim 223 is positioned between a front face 225 of the frame member 48 and the rear surface of the upper portion 194 of the rear flange of the upper ribs 181A of the cover panel. In this position, the tool 220 can be slid horizontally until the end flange 223 engages with a separation tab 206. By rotating the tool 220, the tip of the flange 223 of the end can be positioned on the decoupling tab 206. After this, when rotating the tool 220, the flange 223 of the end engages the tongue 206 and urges the release tongue 206 and the anti-slip tooth 205 downwards. This separates the fastener 183 from the frame 48, such that the upper retaining section of the fastener 197 can be pulled through the opening 83 in the frame member 48. The tool 220 can conveniently be slid horizontally along an upper edge of the cover panel 73 to repeatedly and quickly release the fastener after the fastener. The bottom of the cover panel 73 can be pulled down to resiliently release the fasteners 184 from the bottom.

Modified Modality The cancel frame 240 (Figure 51) is similar to the cancel frame 44 in which the cancel frame 240 includes spaced apart tubular stiles and a plurality of horizontal frame elements attached to the uprights with opposite faces spaced outward from each other. the sides of the posts. Also the upper horizontal frame member includes a tubular portion, although the frame 240 the upper horizontal frame member is two pieces. In addition, the cancel frame 240 is similar to the frame 44 in that an upper channel is formed in an upper part of the upper horizontal frame member. Still further, both arrangements / constructions allow the horizontal side elements to be adjusted vertically in relation to the upper and lower horizontal frame members, although an upper end of the uprights is butted to a lower part of the upper horizontal frame member, to allow the horizontal frame elements (in which the horizontal row of the holes in their sides are included) to be located exactly among each other. More specifically, the cancel frame 240 (Figure 51) includes a pair of rectangular tubular uprights 241 and upper and lower horizontal frame members 242 and 243, respectively welded to the uprights 241. The intermediate horizontal frame elements, such as the 48- 50 (figures 2-3) can be secured to uprights 241 at various heights as desired. The upper horizontal frame element 242 (FIG. 51A) includes a tubular element 244 and a channel 245 in inverted "" form. The tubular member 244 includes an upper flange 246, a lower flange 247 and sidewalls 248 that join the flanges 246 and 247. The channel 245 includes a horizontal transverse flange 249 and opposed internal vertical flanges 250 and 251 forming a channel space 252. upwards. Two flat top flanges 253 and 254 extend horizontally outward from flanges 250 and 251 and a pair of external side walls 255 and 256 extend downwardly from flanges 252 and 254. External side walls 255 and 256 include a bottom edge which extends in an overlapping or superimposed manner on the side walls 248 of the tubular element 244 to which they are welded. A space 257 is created behind the side wall 255 of the channel and above the upper rim 246 of the tube, and another space 258 is created behind the side wall 256 of the channel and above the upper rim 247 of the tube. A configuration of openings that support the cover panel and openings that hold the furniture component (not shown) identical to the openings 72 and 74 (Figure 5) are formed in the side walls 255 and 257 of the channel in addition to the spaces 257 and 258, in such a way that the cover panel connectors and the hooked brackets can be extended through the openings to the spaces to allow the operative connection of the cover panels 73 and the furniture components (e.g. positioned outside the module, binder trays, shelves and the like). The lower horizontal frame element 243 (FIG. 51) is rectangular and includes an upper flange 260, a lower flange 261 and side walls 262 that connect the upper and lower flanges 260 and 261. The side walls 262 are separated by a distance equal to the side walls 248 in the channel W 245 of the upper horizontal frame element 242, such that their external surfaces are vertically aligned. Notably, the illustrated uprights 241 (Figure 51) extend through an opening in the lower flange 247 of the tubular member 244 and are butt welded to the upper flange 246. Alternatively, the upper end of the uprights 241 may be butt welded. to the lower flange 247 of the tubular element 244. A rectangular opening is formed in the lower flange 247 (and also in the upper flange 246 if desired) of the tubular element 244 to receive the upper end of the studs 241. This allows the piece vertical 241 is extended into the interior of the tubular upper horizontal frame member 242. Advantageously, this allows the upper horizontal frame member 242 to be adjusted / fixed vertically in relation to the lower horizontal frame element 243 before the upper horizontal frame member 242 is welded to the uprights 241. In particular, the location of openings in the side walls 255 is controlled very accurately in relation to the flat upper flanges 253, in such a way that an upper part of the flat upper flanges 253 are used as reference surfaces during the fixing. The result of this welded assembly is a structurally strong upper horizontal frame member 240 that is adapted to carry loads, so that it can support collecting trays over predetermined relatively long distances, as discussed above with respect to frame 44. The concurrent result is a cancel frame 240 having horizontal elements spaced vertically very accurately with apertures located exactly corresponding thereto to receive fasteners that hold the cover panel on the deck panels and exactly additional openings to receive hooked brackets for hold furniture components. This particular process / method of construction of a cancel frame including the fixing of an upper flat surface and the vertical adjustment, fixing and welding of horizontal frame elements in relation to the upper flat surface and / or fixing the front openings on the sides in an upper frame element for precisely locating horizontal rows of openings is new and also provides surprising and unexpected results in terms of manufacturing capacity and quality. Notably, the assembly and fixing method and method described above are equally applicable to the frames 44, 45, 120 and 240. Rectangular openings 264 and 265 (Figure 51) are formed in the upper and lower horizontal frame elements 242 and 243, respectively, to provide passages or steps for the channeling of wires and services through them. The openings 264 and 265 closest to the ends of the frame members 242 and 243 include internal portions that form a square opening 266 when matched to the uprights 241, which square opening 266 is adapted to receive the bracket or connector 170 of square tubular stacking (figures 55-58). (Compare with figures 29 and 30). The stacking frame 270 (FIG. 55) includes uprights and bottom horizontal frame members 271 and 272 and 273 that are essentially identical to the corresponding components of the base frame 240. The base frame 240 is different from the stacking frame 270 in FIG. that the base frame 240 includes leveling elements (not shown but see figures 2 and 12). The leveling elements are not shown in figure 55 on the base frame 240 in such a way that the square hole 266 is easily visible. However, the leveling elements include a hexagonal nut (such as the nut 58 in Figure 12) located in the square opening 266 and a leveling screw (such as the threaded rod 59 in Figure 12) that is threadably engaged with the nut and extending under the lower horizontal frame member 243 to engage with a floor channel (see Figures 22-23 and 39-40). To mount the stacking frame 270 to the base frame 240, the stacking frame 270 rests on the base frame 240. After this, the stacking connector 170 is extended through the lower horizontal frame member 243 on the base frame 240 and through the upper horizontal frame member 272 on the stacking frame 270 at a site adjacent to its vertical portions 241. and 271. The screws 172 are extended to the vertical piece 241 and 271 to secure the stacking connector 170 and in turn the stacking frame 270 in place on the base frame 240.
