Description

[Detailed Description of the Invention] (Industrial Application Field) The folding door according to the present invention is used for opening and closing an opening such as a storage door.

(Prior Art) Folding doors of various structures have been conventionally used to open and close openings such as storage doors.

A folding door generally has a structure in which one edge of a plurality of adjacent panels is swingably coupled to each other, and a pin is provided on at least one panel by projecting pins from both upper and lower surfaces of the other end of each panel. The guide rails fixed to the upper and lower edges of the opening are movably engaged with each other.

For example, in the case of the folding door shown in FIG. 15, one of the pair of panels 1a and 1b swingably connected to each other is one panel 1a.
The pins protruding from both upper and lower ends of the panel are pivotally supported by a support block or the like fixed to the guide rail 2, and the pins protruding from both upper and lower ends of the other panel 1b are attached to the guide rail 2 with respect to the guide rail 2. It is displaceably engaged in the length direction.

In the case of the structure shown in FIG. 15, when the pins protruding from both upper and lower end portions of the panel 1b are moved along the guide rails 2, both panels 1a and 1b swing around the pins. Meanwhile, the opening existing between the pair of upper and lower guide rails 2 is opened and closed.

In the case of the folding door shown in FIG. 16, both panels 1a,
Pins protruding from both upper and lower surfaces of the end portion of 1b are engaged with the guide rail 2 so as to be displaceable in the length direction of the guide rail 2.
