Description

  The present invention relates to a folding door device, and more particularly to a folding door device used as a door on a part of a partition wall or as an opening / closing door of a storage such as a cabinet.

  Conventionally, it is known to use a folding door as a door provided at a part of a partition wall or as an opening / closing door provided at an opening of a storage such as a cabinet. This folding door is constructed by arranging the connecting edges of two panel bodies close to each other and connecting them so that they can be bent with a hinge having a rotating shaft in a direction along the connecting edges. Are in a straight line and the opening is closed, and the two panels are turned and bent approximately 180 degrees to be in a superposed state and the opening is opened. Usually, folding doors are constructed by connecting hinges as hinges on the back side of the two panel bodies, and the connecting edges of both panel bodies protrude forward and provide handle on the side where they bend and bend, The gap between the connecting edges of both panel bodies changes when the folding door is bent and extended. Especially when closing the folding door, the gap between the connecting edges becomes small and there is a risk of pinching the fingers. Generally, it is provided at a position.

In Patent Document 1, both ends of a hinge fitting are rotatably connected to one end of a joint plate material mounted on corresponding side end faces of two panel bodies, and the gap between both panel bodies is closed with the hinge fitting, A folding door device is described in which, when the panel body is straightened by inclining the end face of each joint plate material, a space opened in a V shape is formed by both joint plate materials so as not to pinch fingers. . However, the folding door device of Patent Document 1 must be provided with a V-shaped groove having a sufficiently large width at the connecting portion of the panel body so as not to pinch fingers, and the panel body is straightened to close the space portion. At this time, this V-shaped groove appears on the front surface, which impairs the appearance. Moreover, in order to form an inclined surface on the end surface of the panel plate, a special panel body structure must be provided, and a die for a press molding machine needs to be prepared accordingly, resulting in high costs. Furthermore, since the link structure has a two-point pivot shaft with both ends of the hinge fitting pivoted to the joint plate material of each panel body, it can be easily estimated that the opening / closing locus of the panel body becomes unstable.
