Description

本発明は、折戸装置に係わり、更に詳しくは空間を演出し、あるいは空間を仕切るための設備を構成するポストあるいはパネル壁と、横ビームで形成された開口部に設ける折戸装置に関するものである。 The present invention relates to a folding door device, and more particularly to a folding door device provided in an opening formed by a post or a panel wall and a lateral beam that constitutes equipment for producing a space or partitioning a space .

従来から間仕切壁の開口部に設ける折戸は各種提供されている。このような折戸は、開口部の上部に位置する横ビームや横枠にレールを取付け、該レールに転動する車輪を備えた吊支部材で折戸を構成する各パネル体を垂直な吊支軸に対して回動可能に支持し、隣接するパネル体はヒンジ機構にてジグザグに屈曲可能に連結された構造が一般的である。 Conventionally, various folding doors provided at the opening of the partition wall have been provided. Such a folding door is a vertical suspension support shaft that is constructed by attaching a rail to a horizontal beam or a lateral frame located at the upper part of the opening, and each panel body constituting the folding door with a suspension support member having wheels that roll on the rail. In general, the adjacent panel bodies are connected to each other so as to be bent in a zigzag manner by a hinge mechanism.

特許文献１には、戸先側パネルと戸尻側パネルの対向する端部にそれぞれ目地部材を取付け、両目地部材の間に断面略８字形の閉塞部材を配置し、該閉塞部材の上下端に等角ヒンジを取付け、該等角ヒンジの本体部の二つの可動中心に対してそれぞれ回動するウイングを対応するパネルの上端部に固定し、戸先側パネルと戸尻側パネルが閉塞部材に対して等角に屈曲する構造の折戸装置が開示されている。隣接するパネルの屈曲部に前記閉塞部材を介在させることによって、両パネルが完全に平行になるまで折り畳むことが可能である。 In Patent Document 1, joint members are attached to opposing ends of the door-end side panel and the door-end side panel, respectively, and a closing member having an approximately 8-shaped cross section is disposed between the joint members. An equiangular hinge is attached to the upper end of the corresponding panel, and the door end side panel and the door bottom side panel are closed members. A folding door device having a structure that is bent at an equiangular angle is disclosed. By interposing the blocking member between the bent portions of adjacent panels, the panels can be folded until they are completely parallel.

前記等角ヒンジは、ユニット化され、小さな本体部の内部に歯車が組み込まれ、二枚のウイングがそれぞれの回転軸を中心に同調して回動するようになっている。しかし、前記等角ヒンジは、耐久性が要求される精密部品で高価なものであるので、コスト高となる傾向がある。また、前記等角ヒンジの本体部の各回転軸に、回転角度を制限するストッパーが内蔵されているものもあるが、一旦直線状になってもキックバックにより若干屈曲状態に戻るといった現象が生じ、隣接するパネルを確実に直線状に維持することができなかった。 The equiangular hinge is unitized, and a gear is incorporated in a small main body so that the two wings rotate in synchronization with the respective rotation axes. However, the equiangular hinge is a precision part that is required to be durable and expensive, and therefore tends to be expensive. In addition, although there is a built-in stopper for limiting the rotation angle on each rotation shaft of the main body portion of the equiangular hinge, a phenomenon occurs that even if it becomes linear, it returns to a slightly bent state due to kickback. Adjacent panels could not be kept straight.
