Description

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 .

  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.

  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.

  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.
