Abstract

(57)【要約】 【目的】 軽量化に適した簡単な構造を持ち、保管,搬 送時に折り畳むことができる作業足場を提供する。 【構成】 中央線に沿って二つ折可能にヒンジで連結さ れた2枚の天板110,120の展開状態における四隅 近傍の下方に、4本の支脚210,220,230,2 40を配置する。支脚210と220及び230と24 0は、屈曲可能な連結桟215,225,227,22 9で連結されている。支脚220と230及び240と 210は、長さが可変の伸縮桟234,244で連結さ れている。体格位置にある支脚210と230及び22 0と240は、軸受けを介して一体化されたアングル桟 250,260及び270,280で連結されている。 軸受けに展開機構300の主軸310が挿通され、天板 110,120の合せ面に沿ってスライダ330が移動 可能に設けられている。スライダ330は、リンク片3 41〜344を介してアングル桟250,260,27 0,280に連結されており、ガイドによって水平移動 する。
PURPOSE: To provide a portable working scaffold with a simple structure suited for weight reduction and to enable the scaffold to be folded during storage and transportation. CONSTITUTION: Four supports 210, 220, 230, 240 are installed below near the four corners of two top boards 110, 120 being extended, the top boards being connected together by hinges in such a way that they can be folded into two along a center line. The supports 210, 230 are connected respectively to the supports 220, 240 by bendable connecting battens 215, 225, 227, 229. The supports 220, 240 are connected respectively to the supports 230, 210 by variable-length expansion battens 234, 244. The opposite supports 210, 230, and 220, 240 are connected together by angled battens 250, 260 and 270, 280 which are integrated together via bearing. The main shaft 310 of an extension mechanism 300 is passed through the bearings, and a slider 300 is provided in such a way as to be movable along the mating surfaces of the top boards 110, 120. The slider 330 is connected to the angled battens 250, 260, 270, 280 via links 341 to 344 and is moved horizontally by guides. COPYRIGHT: (C)1996,JPO
