As described above, it is characterized in that the plurality of telescopic legs are connected to each other by the wires and the telescopic legs are synchronously extended to stably move the top and bottom.

Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本案は天板の高さを自由に変えられる昇降テーブルに関するものである。 The present invention relates to a lifting table in which the height of the top plate can be freely changed.

【0002】[0002]

【従来の技術】[Prior Art]

従来の昇降テーブルは2本以上の脚を同期的に伸縮させる事が困難なため一本 の脚で天板を支えていた。 In a conventional lifting table, it is difficult to extend and contract two or more legs synchronously, so one leg supports the top plate.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

けれども一本脚で天板を支える場合、安定上大きな天板を支える事が出来ずま た脚の床に接する部分に大きな張出しが必要であるが、これは使用上邪魔になり 実用上問題であった。 However, when supporting the top plate with one leg, it is necessary to have a large overhang on the part of the leg that comes into contact with the floor because it could not support the large top plate for stability. there were.

【0004】[0004]

【問題を解決するための手段】[Means for solving the problem]

本案は2本以上の脚をワイヤーで相互に連結して同期的に伸縮させる事により 構造簡単で、細い邪魔にならない複数脚の昇降テーブルを提供するもので、図1 に示すように天板1と一体的に結合した上脚21,22に夫々摺動自在に結合し た下脚31,32を、上脚又はそれと一体的に結合したフレーム2に設置した、 回転自在のローラー51,52,61,62,71,72を下記の順序で経由し てワイヤーで相互に結合したものである。 ワイヤー81は下脚31に固定されたピン41に一端を結合しローラー51, 71,62を経由して他端を下脚32に固定されたピン42に結合されている。 ワイヤー82は一端をピン42に結合しローラー52,72,61を経由して他 端をピン41に結合されている。 ワイヤー81の中間部に別のワイヤー6の一端を固定し、ガススプリングの伸 縮部4に固定された回転自在のローラー5を経由して、他端をフレーム2に固定 する。 This proposal provides a multi-leg lifting table with a simple structure by connecting two or more legs to each other with wires and expanding and contracting in a synchronous manner. As shown in FIG. The lower legs 31 and 32 slidably coupled to the upper legs 21 and 22 integrally coupled to the upper legs and the frame 2 integrally coupled to the lower legs 31 and 32, respectively, are rotatable rollers 51, 52 and 61. , 62, 71, 72 are connected to each other with wires via the following order. The wire 81 has one end coupled to the pin 41 fixed to the lower leg 31 and the other end coupled to the pin 42 fixed to the lower leg 32 via the rollers 51, 71 and 62. The wire 82 has one end connected to the pin 42 and the other end connected to the pin 41 via the rollers 52, 72, 61. One end of another wire 6 is fixed to the middle part of the wire 81, and the other end is fixed to the frame 2 via the rotatable roller 5 fixed to the expansion / contraction part 4 of the gas spring.

【0005】[0005]

【作用】[Action]

図1のように天板が降下した位置にある(下脚が上脚に押込まれている)とき ガススプリング4は圧縮されて短縮状態にあり、その反発力により矢印11に示 す方向に伸長するとローラー5を介してワイヤー6が引張られそれと結合された ワイヤー81も矢印13に示す方向に引張られる。 このためその一端が結合されたピン41が固定された下脚31が下に押出される 即ち伸縮脚が伸びる事になり天板が上昇する。この時同時にピン41に結合され たワイヤー82は下脚31の移動量と同じだけ矢印14に示す方向に引張られ、 そのためその一端が結合されたピン42とそれが固定されている下脚32が下に 押出される。この押出される寸法は前記のように下脚31と同じであるため、天 板1は傾く事なく上昇する。この状態を図2に示す。 天板を降下させるときは天板を下方向に押せば前記の反対の作用により、下脚 31,32が同期的に押込まれ、ワイヤー81,82,ローラー5を介してガス スプリングの伸縮部4が矢印12に示す方向に押込まれ勢力を蓄積される。 When the top plate is in the lowered position as shown in Fig. 1 (the lower leg is pushed into the upper leg), the gas spring 4 is compressed and in a shortened state, and when the repulsive force extends in the direction indicated by arrow 11, The wire 6 is pulled through the roller 5 and the wire 81 connected thereto is also pulled in the direction indicated by the arrow 13. For this reason, the lower leg 31 to which the pin 41 having one end coupled thereto is fixed is pushed out, that is, the telescopic leg is extended and the top plate is raised. At this time, the wire 82 connected to the pin 41 is simultaneously pulled in the direction indicated by the arrow 14 by the same amount as the movement amount of the lower leg 31, so that the pin 42 having one end thereof connected and the lower leg 32 to which the pin 42 is fixed are moved downward. Extruded. Since the pushed-out size is the same as that of the lower leg 31 as described above, the top plate 1 rises without tilting. This state is shown in FIG. When lowering the top plate, if the top plate is pushed downward, the lower legs 31 and 32 are synchronously pushed in by the opposite action, and the expandable portion 4 of the gas spring is pushed through the wires 81 and 82 and the roller 5. It is pushed in the direction shown by arrow 12 and the force is accumulated.

【0006】[0006]

【実施例】【Example】

ガススプリングの固定部3はフレーム2に固定されている。ガススプリングの 伸縮部とワイヤー81を直接結合せず、ワイヤー6をローラー5を経由して結合 する事により、ガススプリングの伸縮量の2倍の伸縮量で天板を昇降させる事が 出来る。 図3に4本脚の場合のワイヤーの結合状態を示す。天板及び上脚は省略して描 いてある。ワイヤー7は天板を持上げたとき、下脚が自重で下がるのを防ぐため である。 ガススプリングはロックピン8を押す事によりガス圧で伸長し、ロックピン8 を戻す事により任意の位置でロックする構造のものが、他にブレーキ機構を必要 とせず便利である。 The fixed portion 3 of the gas spring is fixed to the frame 2. By connecting the wire 6 via the roller 5 without directly connecting the expansion / contraction part of the gas spring and the wire 81, the top plate can be moved up and down by an expansion / contraction amount twice the expansion / contraction amount of the gas spring. FIG. 3 shows a wire connection state in the case of four legs. The top plate and upper legs are omitted in the drawing. The wire 7 is to prevent the lower leg from being lowered by its own weight when the top plate is lifted. The gas spring has a structure in which it is extended by the gas pressure by pushing the lock pin 8 and is locked at an arbitrary position by returning the lock pin 8, which is convenient because no other braking mechanism is required.

【考案の効果】[Effect of the device]

以上のようにワイヤーで各伸縮脚及びガススプリングを連結する事により、簡 単な構造で複数の伸縮脚を同期的に伸縮させる事ができるため、天板の大きさに 制約される事なくまた実用上邪魔にならない細い脚で昇降テーブルを製作するこ とが出来、実用上著しい効果を有するものである。 By connecting each telescopic leg and gas spring with the wire as described above, it is possible to synchronously extend and contract multiple telescopic legs with a simple structure, so that there is no restriction on the size of the top plate. The lifting table can be manufactured with thin legs that do not interfere with practical use, which has a remarkable practical effect.
