Description
April 20, 1954 E. G. FERRIS YCOLLAPSIBLE STAND Filed Oct. 9. 1950 EDWIN uy F'EP/E/S,
IIVVENTOR.
M 4 7' TOPNEY Patented Apr. 20, 1954 UNITED STATES ATENT OFFICE This invention relates to stands for supporting special articles, and more particularly to collapsible or folding stands.
The art of hooked-rug making has been developed largely as the hobby, or avocation, of persons who, deriving their principal source of income from some other source, look to hooked rug making as a means of relaxation and/or of supplementary income, to which they can turn in their spare time. The equipment which they employ is therefore preferably of a readily portable nature, permitting it to be stored away, as in a suitable closet, between the periods of its use; and it is with this desirable characteristic of apparatus of the general ty e indicated in mind that the collapsible stand of the present invention has been developed.
It is, therefore, an object of my present invention to provide a collapsible stand for sup porting a frame of the type commonly employed in the production of hooked rugs, the stand being so constructed that when erected to its operating arrangement, it is possessed of ample strength and rigidity to enable it to support the frame and the relatively heavy hooked rug in the production of which it is being employed, and yet which is so light that it can be collapsed, opened, and moved about with a minimum of efiort.
Another object of the invention is to incorporate a unique bracing mechanism into the stand, which, when the stand is erect and in operating arrangement, adds materially to its-strength and rigidity, and which, when the stand is collapsed, serves to interconnect the several parts thereof permanently, thus presenting a single, unitary structure havingv no loose parts apt to become lost when the stand is not in use.
A further object in this connection is to 'design the bracing mechanism already referred to, and to connect it to the other parts of the stand, in such a manner that it affords especial convenience by permitting the stand to be folded to the smallest possible over-all dimensions, thus permitting its being shipped in the smallest possible carton and permitting its being stowed away in a relatively small space.
The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself to, the showing made by the said drawings and escrip- 1 Claim. (Cl. 248-165) tively.
tion, as I may adopt variations of the preferred form within the scope of my invention as set forth in the claim.
Referring to the drawings:
Figure 1 is a perspective view of acollapsible stand incorporating the principles of the present invention and illustrating themanner of its use in supporting a conventional frame of the type commonly employed in the manufacture of hooked rugs.
Figure 2 is an enlarged, detail view in vertical section taken upon th line 2-2 of Figure l, with the direction of View as indicated.
Figure 3 is a perspective view of the stand of Figure l in its collapsed arrangement.
Specifically describing that embodiment of my present invention which has been chosen for illustration and description herein, my improved, simplified, collapsible stand consists essentially of two
end members6, a
rail member7 whereby the
end members6 are interconnected and two combined link and brace members 8 each of which is associated with one of the
end members6 and serves to permanently connect that end member 5 to one end of the rail member i so that all parts of the entire stand are incorporated into a unitary structure having no loose parts, thus avoiding the danger of any parts becoming separated from the others and misplaced even when the stand is collapsed and stowed away between periods of use.
Each of the
end members6 comprises a transverse bar ll, each end of which is provided with a supporting foot I'Z'preferably in the form of a resilient tip I3 fitted 'upon the down-turned end of the piece of tubing of which the bar I l preferably is composed. A'rigid post M extends upwards, preferably vertically, from the mid point of the bar II of each
end member6, preferably being welded thereto at the lower end of the post It as indicated at I6, and also preferably being provided with angularly extending braces I1, each of which is welded at its upper and lower ends to the
post14 and the bar II respectively, as indicated at I8 and I9 respcc- Inasmuch as each of the posts M also is preferably composed of suitable metal tubing, I prefer to provide a closure cap 2| for the upper end of each
post14, which not only adds to the finished appearance of the entire stand, but also provides a suitable, smooth upper terminal capable of avoiding snagging the fabric of a rug being produced with the aid of the'stand.
Adjacent theupper end of each post M a
small hole22 is provided for the reception ofthreaded pins or
bolts23, thus making it possible to mount a
conventional frame24 of the type commonly employed in the production of hooked rugs.
Such frames24 are commonly provided with axially aligned
bolts23 at the midsection of the
end members26, these
bolts23 being rigidly secured to the end members 25. Consequently, the
holes22 are large enough for the
bolts23 to rotate freely therein, permitting the frame 2 1 to be rotated about the common axis of the two
bolts23 so that the operator can move it to any desired osition of pivotal adjustment.
As a further item adapted to afford convenience to the user, I attach one end of a short length of
chain21 to each post 4 a short distance below the upper end thereof, each chain 2'! being of such length that its other end can be engaged upon a
hook28 which is provided for that purpose upon the inner edge of the associated
end member26 of the
frame24 between the axis of the
bolts23 and the
top member28 of the
frame24 and thereby limit the tilting motion of the frame toward the operator to that position in which the frame slopes at approximately 30 or from the horizontal.
The rail member also preferably is composed of a suitable length of
tubing31 and a short length of preferably
flat plate32 secured as by welding 33 to each end thereof in position extending across the end in a plane to which the axis of the tubing 3! is perpendicular and for a sufficient distance both to the back and front of the
tubing31 for
bolts34 carried by the transverse bars II of the
end members6 to be seated within
slots36 in the
plates32. This permits nuts, preferably
wing nuts31, carried by the bolts A4 to be tightened against the
plates32 and thereby to clamp the ends of the rail member "I rigidly into engagement with the inner faces of the bars i of the
end members6 and thereby to rigidly interconnect the
end members6 and the rail member I with the posts l4 extending vertically upwards parallel with each other and spaced apart by a distance substantially equal to the length of the
frame24.
In addition to their function of permanently uniting all parts of the stand into a unitary structure, the members 8 also serve as braces to add rigidity and strength to the posts I4 in their described vertical positions when the end members E are securely clamped to the ends of the rail member I. With this added function of the members 8 in view, each member 8 comprises two
links41 and 42 pivotally interconnected adjacent their proximal ends as by
rivets43 and with their distal ends pivotally attached as by
rivets46 and s1 respectively to the rail member 1 and to the associated post [4 respectively. When the stand is erect, i. e., in its operating arrangement, the two links 4| and 42 of each member 8 are substantially in axial alignment and sloping at substantially 45 downwards from the associated
post14 toward the mid portion of the
rail member7 but when it is desired to collapse the stand, after the
frame24 has been removed therefrom, the
end members6 can be released from their rigid engagement with the
clamping plates32 by loosening the
wing nuts31 and then raising each
end member6 with respect to the associated end of the rail member 1 in pivotal motion about the axis of the
lower rivet46 and, preferably, without completely removing the wing nuts 3? from their associated
bolts34. The stand can then be collapsed by continuing the pivotal motion of each lower link 4! about the axis of its bers in position to extend through said apcl associated
lower rivet46 until it lies substantially in the horizontal plane of the rail member l. However, inasmuch as the preferred proportionate dimensions of the constituent portions of my frame are such that the length of each post It is substantially the same as the length of the rail member I, if the folding motion of each
end member6 were to be completed without pivoting the
links42 and 4| out of their axially aligned arrangement (in which they are illustrated in full lines in Figures 1 and 2) the stand would be collapsed with the top end of each post It projecting for a considerable distance beyond the opposite end of the rail member I. However, by swinging the
upper link42 of each member 2'! about the axis of the
rivet42 whereby it, the
upper link42, is pivoted to the proximal end of the lower link 4! of the associate member 8, as illustrated in broken lines in Figure 2, and in the opposite direction of rotation from that in which the lower link 4! is swung and until the distal ends of the two links ll and 52 are disposed closely adjacent each other (as illustrated in Figure 3) the end members 5 will come to rest in neatly stacked relationship with each other and with the rail member 1 with the entire collapsed frame occupying a space the length of which is only slightly greater than any one of the members 5 or 1. This arrangement of course ma es for economy of space both in the matter of stowing the collapsed frame away between periods of use and also in the matter of packaging for shipment, inasmuch as it permits the use of a considerably smaller shipping carton than would be required if the parts of the frame did not nest in the described compact arrangement.
When unfolding the stand so as to permit the
frame24 to be mounted thereupon in operating position, of course the reverse procedure is followed, care being exercised when the end members s assume their final positions with their pcsts It erect, to press the links M and 2 into axial alignment and slightly therebeyond, i. past their dead center position as illustrated full lines in Figure 2. Preferably a shoulder 5% is provided upon the
end52 of the link e2 which projects beyond the pivot pin .3, which shoulder 5i comes to rest within a socket 523 or other suitable abutment carried by the link it as this past dead center position is achieved, as to retain the links 4| and 42 in their bracing position and thereby preventing accidental collapsing of the stand.
I claim:
prising a transverse bar, a supper sooiated with each end thereof and p e with and upstanding from said bar, a
her, a frame, means associated with each of se i end members for releasably securing it rail member for pivotal motion about tending through said bars adjacent tn r ends, means associated with each of se members for releasably securing it to member, each of said securing means co a plate rigidly secured to the said rail member and extending in a p which the axis of said rail member is lar, said plate having an aperture each side of said rail member, bolts :1 said bar of the associated one of em and a nut threaded on each of said bolts i n said plate can be clamped rigidly but releas 54 against a side of said bar, and a combined link and brace member permanently connecting each of said end members to said rail member and thereby uniting all of said members into a unitary structure, each of said combined link and brace members being pivotally connected at one end thereof to said associated end member and at the other end thereof to said rail member whereby said associated end member can be swung from erect position to collapsed position substantially parallel to said rail member, and each of said combined link and brace members comprising a pair of links pivotally connected to each other for movement optionally into folded relation with their distal ends adjacent each other whereby the associated ends of said rail member and the associated one of said end members can be brought into close proximity as said end member is swung to said collapsed position, or into substantial alignment with each other whereby they co-operate with each other to define a brace extending obliquely between said rail member and said associated end member to rigidly interconnect them while extending angularly with respect to each other, and a stop on one of said links engageable with the other of said links to limit pivotal movement thereof with respect to each other when they have swung only slightly past their said aligned position.
