PROBLEM TO BE SOLVED: To solve the problem of desiring a countermeasure against an accident of inflicting an injury on a passerby of a peripheral part when its broken piece drops, since its front edge vertical part-cracking accident is found here and there by mischief of a passenger, in a protective device conventionally provided in a wedge-shaped space formed of the building ceiling proximal to the outer edge of a handrail.SOLUTION: The present invention for solving this problem is a protective device 9 composed of a fixed protective plate 4 fixed to a fixing body 2 on the innermost side of a wedge-shaped space Q formed of a step 1A for moving by connecting a horizontal passage and an inclined passage in an endless shape and the fixing body 2 proximal at a horizontal interval (m) between a handrail 1B and the outer edge of the handrail 1B and a substantially trapezoidal movable protective plate 7 rockably suspended by the fixing body 2 on its near side, and is formed as the protective device 9 of respectively constituted in three-layers out of protective pieces 44 and 77 having a several-cm width of sticking a front edge vertical part Sa of the fixed protective plate 4 and the movable protective plate 7 to both side surfaces of the fixed protective plate 4 and the movable protective plate 7.SELECTED DRAWING: Figure 3
【課題】 従来、ハンドレールの外縁に近接する建屋天井等で形成される楔状空間に設けられる保護装置は、乗客のいたずらによりその前縁垂直部が割れる事故が散見され、その破片が落下して周辺部の通行人に危害を与える事故の対策が望まれていた。【解決手段】 この問題を解決するため本発明は、水平路と傾斜路を無端状に連結されて移動するステップ1Aと、ハンドレール1B等と、ハンドレール1Bの外縁との間に水平間隔mを空けて近接する固定体2とで形成される楔状空間Qの奥側に、固定体2に固定される固定保護板4と、その手前側にあって固定体2に揺動自在に吊下げられる略台形状の可動保護板7からなる保護装置を備えたものにおいて、固定保護板4と可動保護板7の前縁垂直部Saを、固定保護板4及び可動保護板7の両側面に貼りつけられた数cm幅を有する保護片44、77とで各々三層構成とするなどした保護装置9とした。【選択図】図3
