TELESCOPIC HANDRAIL ATTACHED TO INCLINED SUPPORT
To provide a telescopic handrail attached to an inclined support to solve a problem such that: there is a stepladder with a handrail for the safety in high-lift work, but it is impossible to store it in a shortened state and make it compact when not in use; there is a stepladder in which a handrail can be extended/contracted along parallel supports, but it makes rungs narrow; there is a stepladder which can be extended/contracted along an inclined support, but it cannot be extended/contracted properly unless it is extended/contracted while keeping a balance so that the length of the support of the handrail is the same in the right and left; and there is no stepladder which can be extended/contracted with a single action.SOLUTION: It has been impossible to extend/contract at once an inclined support by holding a handle only with a structure allowing extension/contraction of the inclined support side and extension/contraction of the length on the handle shaft side. In the present invention, a telescopic handrail is configured by combining simple structural members such as square pipes, and in addition to the extension/contraction of a straight portion, a connection angle fixing bracket is provided so as to extend/contract two shafts of the inclined supports at once by an operation with the handle.SELECTED DRAWING: Figure 1
【課題】高所作業の安全のため手すりを付けた脚立があるが、使わない時は短く収納してコンパクトにしておきたい。手すりを平行支柱に沿って伸縮できるようにした脚立はあるが、踏み桟を狭くしてしまう。傾斜支柱に沿って伸縮収納できるようにしたものも出ているが、手すりの支柱を左右同じ長さにするようにバランスを取って伸縮しないと引っかかってうまく伸縮できない。ワンタッチで伸縮できるようなものが出ていない。【解決手段】傾斜支柱側の伸縮とハンドル軸側の長さを伸縮できる構造だけではハンドルを持って傾斜支柱を一挙に伸縮することはできなかった。本発明は角パイプ等の簡易な構造材料を組み合わせて伸縮手すりを構成し、直線部の伸縮に加えて接続角度固定金具を備えることでハンドルを持っての操作で傾斜支柱２軸を一挙に伸縮できるようにしたものである。【選択図】図１
