活動臂架結構Mobile boom structure

本創作係有關於一種支撐懸臂結構，特別是可選擇性的依不同負載裝置，而自由調節支撐力量，並且在不干涉支撐懸臂自然的運動路線下，自動且及時補償支撐力量之一種活動臂架結構。The present invention relates to a movable cantilever structure, in particular, which can selectively adjust the supporting force according to different load devices, and can automatically and timely compensate the supporting force without interfering with the natural movement path of the supporting cantilever. structure.

按，習知支撐懸臂提供負載裝置(如顯示器)，以懸吊的方式設置，因應不同實施環境與實施方式使用。而各式支撐懸臂結構不同，例如以下習知前案。According to the conventional support cantilever, a load device (such as a display) is provided in a suspended manner, and is used in accordance with different implementation environments and implementation modes. The various types of support cantilever structures are different, such as the following conventional case.

習知前案M305524號(以下簡稱文獻1)揭示有「一種螢幕支撐懸臂結構，主要包含有夾座、旋轉臂、支撐臂、軸接座、連桿及擺動座所構成，該夾座係為固定之用，被支撐物受夾座、旋轉臂、支撐臂、軸接座、連桿及擺動座等所組成之支撐懸臂結構所支撐懸掛。藉由提供一種具簡易調整被支撐物之液晶螢幕傾斜角度支撐懸臂結構，藉由軸接座可提供支撐臂具傾斜角度之轉動，並由彈性元件提供一定彈力作用，並可令支撐臂形成一股向下拉力，藉以分擔被支撐物重量…」。然而文獻1藉由導槽改變拉扯彈性元件之力量，並利用彈性元件之 反作用力，而分擔被支撐物重量。此一技藝最大的問題，在於無法任意調整支撐臂的擺動。因為彈性元件的力量無法依實施現狀調節，故會限制匹配的負載裝置重量。使得文獻1支撐臂連接負載裝置後，尚必需依賴使用者施予一力量，或扶持或下壓的調整支撐臂至預設高度，再利用鎖附件以迫緊方式達成定位，而緊固支撐臂的傾斜支撐角度(詳見說明書第8頁第二段倒數第3行所揭示)，也由於此一缺失，造成不同體形高度之使用者觀上的不便。且一但支撐臂受力產生向上或向下擺動位移後，即無法自動回復至預設位置。此一現象除造成使用困擾外，亦造成維護上的麻煩與不便。再者，文獻1其支撐臂之擺輻角度受限於樞接座及導槽，以致支撐臂可調整的角度局限於九十度內，顯然無法滿足使用需求。而類似技藝之前案，另可參閱美國專利第US6478275號，亦存有相同之缺失與問題。The former M305524 (hereinafter referred to as Document 1) discloses "a screen supporting cantilever structure, which mainly comprises a clamp seat, a rotating arm, a support arm, a shaft joint, a connecting rod and a swinging seat, and the clamping seat is For fixing, the support is supported by a supporting cantilever structure composed of a clamping seat, a rotating arm, a supporting arm, a shaft socket, a connecting rod and a swinging seat, etc. By providing a liquid crystal screen with a simple adjustment of the supported object The tilting angle supports the cantilever structure, and the shaft joint can provide the rotation of the supporting arm at an oblique angle, and the elastic member provides a certain elastic force, and the supporting arm can form a downward pulling force to share the weight of the supported object..." . However, Document 1 changes the force of pulling the elastic member by the guide groove, and utilizes the elastic member. The reaction force shares the weight of the supported object. The biggest problem with this technique is that the swing of the support arm cannot be arbitrarily adjusted. Since the force of the elastic element cannot be adjusted according to the implementation status, the weight of the matched load device is limited. After the support arm of the document 1 is connected to the load device, it is necessary to rely on the user to apply a force, or to adjust or support the support arm to a preset height, and then use the lock attachment to achieve the positioning in a tight manner, and fasten the support arm. The tilting support angle (as disclosed in the third line of the second paragraph of the second paragraph of the manual) is also caused by the inconvenience of users of different body heights. Once the support arm is subjected to the upward or downward swinging force, it cannot automatically return to the preset position. In addition to causing confusion, this phenomenon also causes maintenance troubles and inconveniences. Furthermore, the swing angle of the support arm of the document 1 is limited by the pivot joint and the guide groove, so that the adjustable angle of the support arm is limited to 90 degrees, which obviously cannot meet the use requirement. Similar to the prior art, see also U.S. Patent No. 6,472,275, which also has the same drawbacks and problems.

另外，習知前案M446467號(以下簡稱文獻2)揭示有「一種顯示器支架結構，包括一快拆組、一上臂、一下臂以及一固定組件，其中該上臂包含一連桿、一固定軸、一滑塊、一螺桿、一螺帽、一彈簧、一後接頭、一定位軸、一第一側蓋、一第二側蓋、一旋鈕等構件所組成，其上臂連桿的兩樞接壁與後接頭固定軸之中心，以及後接頭定位軸中心的距離較短，相對使彈簧被前、後壓縮的行程較小，而具有穩定不回彈並進一步達到平穩的支撐效果…」。雖說，文獻2可於上臂連桿擺動的同時，調整彈簧之壓迫力，解決文獻1所揭示結構上之缺失。 然而文獻2組成構件繁多，組裝成本高，且彈簧被壓縮後之反作用力無法直接回饋給上臂，反是間接的拉扯螺桿後作用於第一、二側蓋才能達成，其間各元件的間隙、公差之抵消或其反作用力，除造成彈簧預期之反作用力，無法及時達成補償之目的外，反而更造成上臂擺輻動作無法順暢的缺失。In addition, the conventional front case M446467 (hereinafter referred to as document 2) discloses "a display stand structure comprising a quick release set, an upper arm, a lower arm and a fixing component, wherein the upper arm comprises a connecting rod, a fixed shaft, a slider, a screw, a nut, a spring, a rear joint, a positioning shaft, a first side cover, a second side cover, a knob and the like, and the two pivot walls of the upper arm link The distance from the center of the fixed shaft of the rear joint and the center of the positioning shaft of the rear joint is relatively short, so that the stroke of the spring is compressed by the front and the rear is relatively small, and the stability is not rebounded and further achieves a stable supporting effect...". Although the literature 2 can adjust the pressing force of the spring while swinging the upper arm link, the structural loss disclosed in the document 1 can be solved. However, the literature 2 has a large number of components, high assembly cost, and the reaction force of the spring after being compressed cannot be directly fed back to the upper arm, but the indirect pulling of the screw can be achieved after the first and second side covers are achieved, and the gaps and tolerances of the components are completed. The offset or its reaction force, in addition to causing the expected reaction force of the spring, can not achieve the purpose of compensation in time, but also causes the upper arm swinging motion to be unable to smoothly disappear.

請再參閱習知前案M368005號(以下簡稱文獻3)揭示有「一種支撐架之擺臂結構，係包括有固定座、懸臂、擺臂、支撐器及連結座，其中在擺臂內部之支撐器包括有外套管、連動塊及彈簧，且外套管底部為穿設有樞接連動塊並限位卡制於擺臂之滑道內滑動之桿件，再於外套管底部外環面之擋環上抵持有彈簧，而連動塊底部設有樞接於懸臂一側樞接塊上之軸桿，俾當擺臂向下或向上擺動時，其擺臂會以底部連接軸為中心作旋轉，而支撐器之連動塊二端桿件及軸桿形成相互作用，使桿件在滑道內位移滑動，形成預期的位移動線，讓彈簧呈推動，而達到操作不同旋轉角度時，其整個擺臂擺動的受力一致…」。由文獻3內容可知，文獻3克服了上述文獻1、2之缺失，但仍有未臻完善之處，例如，文獻3係藉由桿件在滑道內位移滑動，強迫形成「預期」的位移動線，而此一位移動線並非等同於擺臂上、下擺動之自然動線。以致於文獻3的擺臂在上、下擺動時，其滑道會以自身之弧度採硬迫方式推壓桿件，使其牽動連動塊及外套管沿滑道弧度壓縮彈簧，導致彈簧受力時機並非依據擺臂上、下擺動時自然動線的適時位置。反 到是受滑道之弧度所致。也因為如此，勢必干擾擺臂上、下擺動時的自然動線，相對的必然影響擺臂上、下擺動時的流暢性。Please refer to the prior art M368005 (hereinafter referred to as Document 3) for revealing "a swing arm structure of a support frame, which includes a fixed seat, a cantilever, a swing arm, a support and a joint, wherein the support inside the swing arm The utility model comprises an outer sleeve, a linkage block and a spring, and the bottom of the outer sleeve is a rod member which is provided with a pivotal linkage block and is limited to be locked in the slide rail of the swing arm, and is further blocked by the outer annular surface of the outer sleeve The ring abuts the spring, and the bottom of the linkage block is provided with a shaft pivotally connected to the pivoting block on the side of the cantilever. When the swing arm swings downward or upward, the swing arm rotates around the bottom connecting shaft. The two end rods and the shaft of the supporting block form an interaction, so that the rod slides and slides in the slide to form a desired position moving line, so that the spring is pushed, and when the different rotation angles are operated, the whole The force of swinging the swing arm is the same...". As can be seen from the contents of Document 3, Document 3 overcomes the lack of the above documents 1, 2, but there are still some imperfections. For example, Document 3 is forced to form an "expected" position by sliding the rod in the slide. Move the line, and this one moving line is not the same as the natural moving line of the swing arm up and down. Therefore, when the swing arm of the document 3 swings up and down, the slide rail pushes the lever member in a self-rigid manner, so that the linkage block and the outer sleeve are compressed along the slide arc to compress the spring, thereby causing the spring force. The timing is not based on the proper position of the natural moving line when the swing arm is swung up and down. anti- It is caused by the curvature of the slide. Because of this, it is bound to interfere with the natural moving line when the swing arm swings up and down, which inevitably affects the smoothness of the swing arm when swinging up and down.

再者，文獻3藉由滑道之弧度，強迫牽引連動塊及外套管，改變彈性元件之壓迫力量。而文獻3滑道係設置於兩支架上，使得桿件運動受滑道約束，再者各別支撐架之擺臂，其上、下擺輻動線必然有所差異。而文獻3卻企圖藉由規格化的滑道弧度，對應各異的擺臂動線，並於擺臂作動時以約束方式強迫桿件運動。在此一矛盾的結構設計下，又欲求不干擾擺臂自然擺輻之動線，顯與緣木求魚無異。另外，雷同文獻3技藝之前案，可另外參考美國專利第US2011/0260017號，也存有相同之缺失與問題。Furthermore, Document 3 forces the traction block and the outer casing to change the pressing force of the elastic member by the curvature of the slide. The document 3 slide system is set on the two brackets, so that the movement of the rod is constrained by the slide rails, and the swinging arms of the respective support brackets must have different convergence lines of the upper and lower hem. However, the literature 3 attempts to force the movement of the rod in a constrained manner by the normalized slide arc, corresponding to the different swing arm movements. Under this contradictory structural design, it is also desired to not interfere with the moving line of the swing arm's natural swing, which is no different from the edge of the wood. In addition, in the case of the prior art of the same document 3, the US Patent No. US2011/0260017 can be additionally referred to, and the same defects and problems exist.

總上所述，彙整文獻1至3各點缺失，包括：In summary, the points 1 to 3 of the collection are missing, including:

1.文獻1，擺動角度受限使其小於九十度，也無法任意調整支臂擺動，支臂一但被移動後便無法自動回位，而需使用者重新調整，尚且需配合鎖附件定位。1. Document 1, the swing angle is limited to be less than ninety degrees, and the arm swing cannot be arbitrarily adjusted. Once the arm is moved, it cannot be automatically returned, and the user needs to readjust it again, and the lock accessory needs to be positioned. .

2.文獻2，組成構件複雜，不論生產、組裝都容易衍生成本浪費及品質問題，且調節彈簧反作用力回饋不佳，以及調節彈簧反作用力的時機，無法與實際的擺動輻線匹配等。2. Document 2, the composition of the components is complex, regardless of production and assembly are easy to derive cost waste and quality problems, and the adjustment of the spring reaction force is not good, and the timing of adjusting the spring reaction force, can not match the actual swinging radiation.

3.文獻3，桿件作動時受滑道所局限，且滑道強迫彈簧作用力的時間，無法與實際擺臂的擺動路線及時匹配，除會干擾實際的擺動路線外，更會造成擺臂運動不順的缺 失，也由於滑道以強迫方式迫使桿件運動，多次作動磨損後，其擺臂受干擾與不順的現象，將越發明顯。3. Document 3, when the rod is actuated, it is limited by the slideway, and the time when the slide force forces the spring force cannot match the swinging path of the actual swing arm in time, except that it will interfere with the actual swinging route, and the swing arm will be caused. Lack of movement Loss, but also because the slide force forced the movement of the rod, the phenomenon of interference and disobedience of the swing arm after multiple actuations will become more obvious.

有鑑於上述習知技藝之問題與缺失，本創作之主要目的乃在於提供一種懸吊結構，藉此方便使用者可依負載裝置之重量，預先調節一預壓之力量，維持負載裝置於理想位置，並可於擺動的同時，依其自然運動之抛弧形路線，自動且適時的調整預壓力量之一種活動臂架結構。In view of the problems and deficiencies of the above-mentioned prior art, the main purpose of the present invention is to provide a suspension structure, thereby facilitating the user to pre-adjust a pre-stressing force according to the weight of the load device, and maintaining the load device in an ideal position.

是以，上述即為本創作所提供一較佳實施例活動臂架結構的各部構件介紹，接著再將本創作之組裝方式及使用特點介紹如下：首先，請再配合參閱第3至6圖所示，其中，第一桿體12之第二端部，與第二桿體14之第一端部以一鉚釘32樞接。而第二桿體14之第二端部，與第三桿體16之第二端部以一鉚釘34樞接。又第三桿體16之第一端部，與第四桿體18之第二端部以一鉚釘36樞接(如第5圖所示)。餘下，第四桿體18的第一端部，與第一桿體12的第一端以一鉚釘38樞接。藉此構件及其連接方式，俾以形成連動之四連桿組。Therefore, the above is the introduction of each component of the movable boom structure of a preferred embodiment of the present invention, and then the assembly method and the use characteristics of the present invention are as follows: First, please refer to the figures 3 to 6 The second end of the first rod 12 is pivotally connected to the first end of the second rod 14 by a rivet 32. The second end of the second rod 14 is pivotally connected to the second end of the third rod 16 by a rivet 34. The first end of the third rod body 16 is pivotally connected to the second end of the fourth rod body 18 by a rivet 36 (as shown in Fig. 5). Remainingly, the first end of the fourth rod body 18 is pivotally connected to the first end of the first rod body 12 by a rivet 38. Thereby, the members and the connection manner thereof are used to form a linked four-link group.

而支撐元件20之第一端部，藉由鉚釘40樞接於第一桿體12的第一、二端部之間，以及支撐元件20之第二端部與各懸吊元件22的第一端部及預壓裝置24之第一端部(即管件54一端的樞接座62)以一鉚釘42樞接。另外，預壓裝置24之第二端部頂抵於第二桿體14其橫向片46上鎖設之限位片48上，並使栓頭58限位於限位凹部47。又，各懸吊元件22之第二端部，則配合鉚釘44樞接於第二桿體14的第一、二端部之間。藉由上述組裝方式，可將支撐元件20、懸吊元件22及預壓裝置24，容置於 第二桿體14兩翼片之間。The first end of the support member 20 is pivotally connected between the first end and the second end of the first shaft 12 by the rivet 40, and the first end of the support member 20 and the first end of each suspension member 22 The first end of the end and preloading device 24 (i.e., the pivoting seat 62 at one end of the tubular member 54) is pivotally coupled by a rivet 42. In addition, the second end of the preloading device 24 abuts against the limiting piece 48 of the second rod body 14 which is locked on the transverse piece 46, and the bolt head 58 is limited to the limiting recess 47. Moreover, the second end of each suspension element 22 is pivotally connected between the first and second ends of the second rod 14 in cooperation with the rivet 44. The support member 20, the suspension member 22 and the preloading device 24 can be accommodated by the above assembly method. The second rod 14 is between the two fins.

當活動臂架結構10連接一負載裝置時，活動臂架結構10藉由第一桿體12一體形成之套環26固定於一預設點，並以負載裝置端及套環26端之兩點構成一圓圈，使得活動臂架結構10之負載裝置端，會相對於套環26端，形成拋弧形(線)的上、下擺輻運動。When the movable boom structure 10 is connected to a load device, the movable boom structure 10 is fixed to a predetermined point by a collar 26 integrally formed by the first rod body 12, and is at two points of the load device end and the end of the collar 26 A circle is formed such that the load device end of the movable boom structure 10 forms a top and bottom swing motion of the arcuate (line) with respect to the end of the collar 26.

例如，活動臂架結構10會因負載裝置本身重量，造成活動臂架結構10之四連桿組作動，並以套環26處為軸心產生上、下旋擺。同時在活動臂架結構10第二端部(負載裝置連接端)，自上方位置處沿拋弧形路徑朝下方位置移動時，各懸吊元件22與支撐元件20形成相互作用，使各懸吊元件22第一端受限支撐元件20之第二端頂撐，俾使各懸吊元件22以第二端部(鉚釘44樞接處)為軸心產生軸轉，而各懸吊元件22第一端部則以與支撐元件20之第二端樞接處(鉚釘42樞接處)為軸心產生軸轉，並位移推頂管件54向前移動一預設之距離D，且活動臂架結構10下降越低，則此一向前位移量就越大(預壓裝置24的反作用力亦越大)。For example, the movable boom structure 10 causes the four-bar linkage of the movable boom structure 10 to be actuated due to the weight of the load device itself, and the upper and lower swings are generated with the collar 26 as the axis. At the same time, at the second end of the movable boom structure 10 (the load connecting end of the load device), when the upper end position moves along the arcuate path toward the lower position, each suspension element 22 interacts with the supporting member 20 to make each suspension The first end of the element 22 is constrained by the second end of the support member 20, so that the suspension elements 22 are pivoted with the second end (the pivot of the rivet 44) as an axis, and each suspension element 22 The one end portion is pivoted at a pivotal position with the second end of the supporting member 20 (the pivotal position of the rivet 42), and the displacement pushing tube member 54 is moved forward by a predetermined distance D, and the movable arm frame is moved. The lower the lowering of the structure 10, the greater the amount of forward displacement (the greater the reaction force of the preloading device 24).

也由於各懸吊元件22與支撐元件20採樞接方式作動，而有別於習知前案藉由滑道限制動線，使得本創作各懸吊元件22與支撐元件20，可在完全不干涉活動臂架結構10拋弧形擺輻的自然動線下，及時反應並產生向前位移，同步且及時的連動管件54(樞接座62)朝上推擠彈性元件50底端，而彈性元件 50頂端則在螺母56及栓桿52之限位作用下，使彈性元件50的反作用力直接的反應至第二桿體14(即推頂橫向片46而作用至第二桿體14)。Also, since each suspension element 22 and the supporting element 20 are pivotally actuated, unlike the prior art, the moving line is restricted by the slide rail, so that the suspension elements 22 and the supporting element 20 of the present creation can be completely absent. Under the natural moving line of the arcing swing of the interference movable arm frame structure, the reaction is timely and the forward displacement is generated, and the synchronous and timely interlocking pipe member 54 (the pivoting seat 62) pushes the bottom end of the elastic member 50 upward, and the elasticity element The top end of the 50, under the action of the nut 56 and the bolt 52, directly reacts the reaction force of the elastic member 50 to the second rod 14 (i.e., pushes the cross piece 46 to act on the second rod 14).

如此，預壓裝置24於第二桿體14內偏擺位移的同時，會自動形成一即時補償的作用，且彈性元件50的反作用力，並不會造成使用者需另外施予更高的壓力，才能推動活動臂架結構10，反而只需輕鬆施予推力，即可達成推動活動臂架結構10，而調整負載裝置上、下位置。藉以達成活動臂架結構10沿拋弧形路徑上、下擺動時，受力都能保持在趨近一致的狀態，除可確保活動臂架結構10擺動的順暢外，更可達到輕鬆省力的效果。In this way, the preloading device 24 automatically forms an instant compensation function while the yaw displacement of the second rod body 14 is displaced, and the reaction force of the elastic member 50 does not cause the user to apply a higher pressure. In order to push the movable boom structure 10, the thrust boom structure 10 can be easily pushed, and the upper and lower positions of the load device can be adjusted. Therefore, when the movable boom structure 10 is swung up and down along the arc-shaped path, the force can be maintained in a nearly uniform state, and in addition to ensuring smooth swing of the movable boom structure 10, the effect of effortless and effort-saving can be achieved. .

另外，本創作活動臂架結構之預壓裝置24在結構上，提供使用者可依不同需求作彈力大小之調整，以因應實施時，各種不同重量之負載裝置使用。使用者可藉由工具穿伸透孔49(如第4圖所示)，並扭轉栓頭58使栓桿52自旋，而螺母56受第二桿體14兩側之翼片限制，無法隨之轉動，只能沿栓桿52軸向上、下位移。並在螺母56向下位移時，壓縮彈性元件50頂端，而彈性元件50底部則會抵壓在管件54的樞接座62上，使彈性元件50呈現更為緊密的壓縮，增加彈性元件50兩端釋放的反作用力，提供活動臂架結構10所連結之負載裝置較重時，可藉由調節預壓裝置24之彈性元件50，讓活動臂架結構10擺動位移能更為緊實，並可藉由此一反作用力，使負載裝置維持在一預 設高度，方便使用者可任意上、下位移負載裝置，並於外力消失後，依藉此一反作用力而回復至預設高度。In addition, the preloading device 24 of the ergonomic boom structure is structurally provided, and the user can adjust the elastic force according to different requirements, so as to be used in various load devices according to various weights. The user can pierce the through hole 49 (as shown in FIG. 4) by the tool, and twist the bolt head 58 to spin the bolt 52, and the nut 56 is restricted by the fins on both sides of the second rod body 14, and cannot follow The rotation can only be displaced up and down along the axial direction of the bolt 52. And when the nut 56 is displaced downward, the top end of the elastic member 50 is compressed, and the bottom of the elastic member 50 is pressed against the pivoting seat 62 of the tube member 54, so that the elastic member 50 exhibits a tighter compression, and the elastic member 50 is increased. When the reaction force of the end release is provided, when the load device connected to the movable boom structure 10 is heavy, the swinging displacement of the movable boom structure 10 can be made more tight by adjusting the elastic member 50 of the preloading device 24. With this reaction, the load device is maintained at a pre-load The height is set so that the user can arbitrarily shift the load device up and down, and after the external force disappears, return to the preset height according to the reaction force.

The body is symmetrically fitted to cover the four-bar linkage, the support member 10, the suspension member 22 and the preloading device 24. And forming a sipe 68 at the sleeve connection, and providing a plurality of clips 66 having a shackle 70, which can be inserted into the shackle 68 by the shackle 70, and optionally along the yoke 68 Move adjustment. The wire clamp 66 is used to constrain the wire body of the load device.
