PROBLEM TO BE SOLVED: To provide an easy-to-use and inexpensive lifting device cover of dental treatment chair in a simple configuration.SOLUTION: The lifting device cover of a dental treatment chair according to the present invention comprises a lifting/lowering stroke range that is opened at least in a front face of the lifting device for lifting/lowering a support member for supporting a treatment table. For covering the front face of the opening part, the lifting device of the dental treatment chair is formed by: facing guide grooves 7 of two rails 8 that have the guide grooves 7 in the longitudinal direction laying the two guide rails along both vertical sides of the opening part respectively and extending from a surface of a base 5 via the lifting device front face and the top part towards the back side slidably engaging parallel ends of a belt-like cover member 9 having flexibility with the facing guide grooves 7 and fixing a substantially longitudinally intermediate part of the belt-like cover member 9 to the support member 3. When the support member 3 is lifted/lowered, the belt-like cover member 9 slides using the guide grooves of the rails 8 as the guides and vertically moves along with the support member 3, while covering the front face of the opening part.COPYRIGHT: (C)2014,JPO&INPIT【課題】簡素な構造で使いやすくかつ安価な歯科治療用椅子の昇降カバーを提供する。【解決手段】本発明の歯科治療用椅子の昇降装置カバーは、治療用台を支持する支持部材が昇降するために、少なくとも昇降装置前面における昇降ストローク範囲が開放された歯科治療用椅子の昇降装置において、前記開放部の前面を覆うために、長手方向にガイド溝7を有する2本のレール8のガイド溝7を対向させるとともに2本のレール8それぞれを、前記開放部の縦方向両側方に沿わせ、ベース5の面から昇降装置前面及び頂部を経て背面側に延設するとともに、対向した前記ガイド溝7に柔軟性を有する帯状カバー部材9の平行端部を摺動自在に係合させ、かつ前記帯状カバー部材9の長手方向における略中間部を前記支持部材3に固定して成り、支持部材3を昇降する際に、帯状カバー部材9がレール8のガイド溝をガイドにして摺動しかつ開放部の前面を覆いつつ支持部材3とともに上下動する。【選択図】図1
