LINING PLATE
PROBLEM TO BE SOLVED: To provide a lining plate a pair of step boards of which, at the time of use, are assembled in a mutually horizontal state, and when not in use, which can be folded into an overlapping state via a mountain fold state in which the pair of step boards are convex upward with a hinge part of a butt part as a bending center from a state in which the pair of step boards are mutually horizontal, can be easily carried, in addition, and reduce the storage space to store accessories and small articles in the storage recesses on the bottom surface of each step board.SOLUTION: A lining plate is composed of a metallic step board body 1 and a pair of right and left fence frame bodies 2 and 2 erected on both sides of the step board body 1. The step board body includes a pair of right and left rectangular plate shaped step boards 1a and 1a which are arranged in parallel with each other by a hinge part E.., and which have substantially the same shape as each other. The pair of step boards are horizontally pivoted so as to be freely folded into an overlapping state via a mutually horizontal state S and a mountain fold state K in which they are convex upward with the hinge part of the butt part as a bending center and the fence frame body is pivotally attached to the step board body so that it can freely rise and fall, and storage concave portions R and R are formed on the bottom surface of each step board.SELECTED DRAWING: Figure 1
【課題】使用時においては、一対の踏板を相互に水平な状態に組み立てることになり、不使用時においては、一対の踏板は相互に水平な状態から突合部分のヒンジ部を折曲中心として上に凸の山折りの状態を経て重合状態に折畳むことができ、容易に持ち運ぶことができ、かつ、保管スペースを小さくすることができ、さらに、各踏板の底面の収納凹部に付属品や小物類を収納することができる。【解決手段】金属製の踏板体１と、踏板体の両側部に立設された左右一対の柵枠体２・２とからなり、踏板体は、ヒンジ部Ｅ・・により左右並列状に突き合わせ配置され、互いに略同形状の左右一対の矩形板状の踏板１ａ・１ａからなり、一対の踏板は相互に水平な状態Ｓと突合部分のヒンジ部を折曲中心として上に凸の山折りの状態Ｋを経て重合状態に折畳自在に枢着され、柵枠体は踏板体に起倒自在に枢着され、各踏板の底面に収納凹部Ｒ・Ｒを形成してなる。【選択図】図１
