Description

この考案は、作業床の高さを段階的に調整可能な振動防止型折り畳み作業床に関するものである。   This invention relates to a vibration-proof folding work floor in which the height of the work floor can be adjusted stepwise.

従来、作業床が折り畳めるだけでなく、その高さまでも段階的に調整出来る作業床は、作業床板自体の荷重が掛かって、伸縮脚の伸長に支障を来すといった事が無く、所望する高さの作業床をワンタッチで展開できる様にする為、作業床の鉛直荷重の伝達を一旦切断した伸縮脚以外から反力を取った折り畳み作業床とを、展開の為の検束運動で有機的に連結していた。   Conventionally, not only the work floor can be folded, but the work floor that can be adjusted stepwise even at its height does not interfere with the extension of the telescopic legs due to the load on the work floor plate itself, and the desired height In order to be able to deploy the work floor with one touch, it is organically connected to the folding work floor that takes the reaction force from other than the telescopic legs that have cut the vertical load on the work floor by the bundling movement for deployment. Was.

しかし、この作業床を折り畳むと、中央付近のヒンジを中心として、左右に分割する作業床が（＋）のモーメント方向に折り畳まれて起立した状態となり、その折り畳まれた作業床を下方で担持する台の伸縮脚が左右に張り出していた。その為、この作業床は横転させて段重ねに横積みにする事が出来なかった。又、展開の為の検束運動を有機的に構成するリンクが複雑となったり、折り畳み可能な作業床とそれを担持する台との総重量が嵩んだり、展開の為に大きな力が必要であり、二人がかりで扱っていた。   However, when this work floor is folded, the work floor divided into right and left is centered on the hinge near the center and folded in the (+) moment direction, and the folded work floor is supported below. The telescopic legs of the base protruded from side to side. For this reason, this work floor could not be rolled up and stacked in layers. In addition, the link that organically configures the bundling movement for deployment becomes complicated, the total weight of the foldable work floor and the platform that supports it increases, and a large force is required for deployment. Yes, I was dealing with two people.

そこで、上記の問題を解決する為に考案したのが下記に示す特許文献である。これは、下端にキャスターを有する４本の伸縮柱と横杆とで１つの背面と２つの側面を有するコの字状の柵を設け、伸縮柱に連結する横杆には、背面に向けて２つの側面が上前及び下前に折り畳める様ヒンジを施装し、背面を構成する２つの伸縮柱の頭部には、貫を横架して双方を連結すると共に、ブラケットを横設してこれに作業床を枢着した機台を設け、該機台を２台背中合わせに連結する事で互いに応答する貫と横杆をそれぞれ一体と成して、頭貫と足元貫とし、該頭貫と足元貫との間にガススプリング付き弾性筋交を施装したものである。
実開平３−１２６５７９ Therefore, the following patent documents have been devised to solve the above problems. This consists of four telescopic columns with casters at the lower end and a horizontal gutter, and a U-shaped fence with one back and two side surfaces. Hinges are attached so that the two side surfaces can be folded forward and downward, and the heads of the two telescopic columns that make up the back are connected to each other by extending the through holes, and the brackets are installed horizontally. This is provided with a machine base pivotally attached to the work floor, and by connecting the two machine bases back to back, the piercing and recumbent that respond to each other are integrated into a head penetration and a foot penetration. The elastic bracing with gas spring is applied between the foot and the foot.

次に、この考案の使用方法について説明すると、まず、図１（折り畳み状態時の正面図）において、最初に天板開き止め用ロックピンを解除し、ヒンジ（２１）（２１’）を支点として（−）のモーメント方向に折り畳まれた左右一対の作業床（１２）の内、一方を水平になるまで、（＋）のモーメント方向に持ち上げる。その後、ヒンジ（９）（９’）を支点に折り畳んだそれぞれの前後側面部を平面視で全体がコの字状態に成る様に展開し、伸縮柱（３）（３’）の頂部に持ち上げた作業床（１２）を持たせ掛ける。そして、次に収納用スタンド（２０）部に折り畳んで収納した伸縮固定式筋交（１９）（１９’）をそれぞれ側面方向に回転させ２本の横振れ防止用伸縮固定式筋交（１９）（１９’）がＸ状に交差する様にして固定し、更に、作業床高さに長さを調整して固定用ハンドル（２２）でしっかり固定する。以下、同様の手順で左右一対の作業床（１２）を展開して、全体として水平に展開した作業床を得る。この作業床（１２）の高さは、それぞれの伸縮柱（２）（２’）（３）（３’）共に同一の高さと成る様に、それぞれのラッチ穴（６）に閂（７）を貫通させて設定するものであるが、図１の様に折り畳む為には、伸縮柱（２）（２’）（３）（３’）の高さを常に最低限度に設定して行うので、作業床（１２）を折り畳んだ状態から展開した時は、常に作業床（１２）は最低限度の高さに位置する。   Next, how to use this device will be described. First, in FIG. 1 (front view in the folded state), the top plate locking pin is first released, and the hinges (21) and (21 ′) are used as fulcrums. Of the pair of left and right work floors (12) folded in the (−) moment direction, one of them is lifted in the (+) moment direction until it becomes horizontal. Thereafter, the front and rear side surfaces folded around the hinges (9) and (9 ') as a fulcrum are developed so as to be entirely U-shaped in plan view, and lifted to the tops of the telescopic columns (3) and (3') Hold the working floor (12). Then, the telescopic fixed type braces (19) and (19 ') that are folded and stored in the storage stand (20) portion are rotated in the lateral direction, respectively, so that two sideways anti-runout telescopic fixed braces (19) are provided. (19 ') is fixed so that it intersects in the X-shape, and further, the length is adjusted to the working floor height and firmly fixed by the fixing handle (22). Thereafter, a pair of left and right work floors (12) are developed in the same procedure to obtain a work floor developed horizontally as a whole. The height of the work floor (12) is the same as that of each of the telescopic columns (2), (2 '), (3), and (3'). However, in order to fold as shown in Fig. 1, the height of the telescopic columns (2) (2 ') (3) (3') is always set to the minimum level. When the work floor (12) is expanded from the folded state, the work floor (12) is always located at the minimum height.

作業床（１２）の高さ調整を行うには、作業床（１２）を展開した状態で行う。この場合、伸縮柱（２）（２’）の高さは最低限度に縮長しており、且つ、足元貫（１６）と筋交（１８）間にはガススプリング（１７）が最縮長の状態で枢着され高さ調整時にガススプリングの反力を利用して持ち上げる力を補う様に成っている。従って、高さを低くする場合は作業床（１２）の上面部を下方向に加圧しながらゆっくり所望の位置まで降下させていき、それぞれの伸縮柱（２）（２’）（３）（３’）の閂（７）を操作して、それぞれの伸縮柱の高さを固定する。又、作業台を折り畳む時は、こりまでの逆の操作を行う。   In order to adjust the height of the work floor (12), the work floor (12) is expanded. In this case, the height of the telescopic columns (2) and (2 ') is reduced to the minimum, and the gas spring (17) is the most reduced length between the foot penetration (16) and the brace (18). It is pivotally attached in the state of, and is designed to compensate for the lifting force using the reaction force of the gas spring when adjusting the height. Therefore, when lowering the height, the upper surface of the work floor (12) is slowly lowered to a desired position while being pressed downward, and each of the telescopic columns (2) (2 ') (3) (3) Operate 閂 (7) of ') to fix the height of each telescopic column. Also, when folding the workbench, the reverse operation up to the rest is performed.

又、折り畳んだ状態では、図１に示す様に左右の作業床（１２）がブラケット（１１）（１１’）のヒンジ（２１）（２１’）部を中心として、（−）のモーメント方向にそれぞれ折り畳まれるので、伸縮柱やガススプリング付き筋交（１８）は、折り畳まれた作業床（１２）間に収納されて、全体として横積みに適する面を左右に形成する。   In the folded state, as shown in FIG. 1, the left and right work floors (12) have the (−) moment direction centered on the hinges (21) and (21 ′) of the brackets (11) and (11 ′). Since each is folded, the stretchable pillars and the bracing with gas spring (18) are housed between the folded work floors (12), and form a plane suitable for horizontal stacking on the left and right as a whole.

次に、この考案の一実施例であるフリーダムステージＬＬタイプの外形寸法及び高さ調整範囲について説明すると、まず、使用時の外形寸法については、作業床部の全長が２２００ｍｍで、全幅が１３００ｍｍである。そして、全高は縮時の１１８０ｍｍ〜伸長時の１９５０ｍｍまで９段階に調整可能で、施工高さとしては、約３１００ｍｍ〜３７００ｍｍに対応可能である。又、折り畳み時の外形寸法は、全幅４４６ｍｍ×全長１３００ｍｍ×全高１２７０ｍｍである。   Next, the outer dimensions and the height adjustment range of the freedom stage LL type which is an embodiment of the present invention will be described. First, regarding the outer dimensions when used, the total length of the work floor is 2200 mm and the total width is 1300 mm. is there. The total height can be adjusted in 9 stages from 1180 mm when contracted to 1950 mm when expanded, and the construction height can correspond to about 3100 mm to 3700 mm. Moreover, the external dimensions at the time of folding are 446 mm in total width x 1300 mm in total length x 1270 mm in total height.
