DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding door and a mounting structure for a folding door which can be used as a door having a wide opening, such as a partition member for interior of a building such as a house or a door of furniture.

[0002]

2. Description of the Related Art Conventionally, a wooden panel having a flash structure in which a decorative material based on a wooden board is adhered to the surface of a wooden frame is used as a unit panel, and this is vertically connected by a connecting member such as a hinge. Folding doors are well known. In addition, decorative panels in which the surface, front and back surfaces of a highly rigid wooden board are decorated are also used as unit panels of the folding door. Further, folding doors made of metal panels are often used depending on the application. Such a folding door connects at least two unit panels in the longitudinal direction with a bendable connecting member such as a hinge or a flexible resin material, and the upper or upper and lower portions thereof are supported by a support material and rail members of an opening frame. It is slidably mounted in a groove or the like, and is folded so that it fits compactly when opened.

[0003] In the case of a metal panel, there is an advantage that a uniform product can be manufactured with good productivity and there is little deformation during use due to moisture or the like, but on the other hand, when it is used inside a building, it feels cheap. In addition, there is a tendency that the range of use is limited because it is inferior to a folding door using a wooden panel, such as touch, texture, sound when an object hits, and the like.

[0004]

[0005]

[0006] In addition, the above-mentioned wooden panel has a disadvantage that it is easily warped or twisted under the influence of moisture. However, once these wooden panels are deformed, it is difficult to correct them at the panel use site, causing a problem that the tightness of the folding door is poor. Because of this,
In the production process, various methods have been devised to prevent various deformations such as warping and twisting by performing moisture conditioning curing of the wood itself and the doors produced, and by making the front and back structures the same. The former requires an extra process, resulting in poor productivity-and the latter has the same decoration as the front side on the back side, despite the fact that the decoration on the back side is useless except for warpage countermeasures. There was a problem that is.

[0007]

The problem to be solved by the present invention is as follows .
It is an object of the present invention to provide a folding door mounting structure that can suppress deformation of a wood-based panel when the panel is used, and does not stand out even if the deformation occurs.

[0008]
