Using a single swing link 52 pivotally connected to the second bracket 51, the front end portion of the door body B extends between the closed position and the open position without contacting the front surface of the door mounting frame A. Since the opening / closing movement guide is provided, as the depth of the door mounting frame A becomes narrower and the opening width becomes wider, the movement trajectory of the tip of the door body 7 that is opened / closed protrudes greatly forward, so that the user can easily give a feeling of oppression. Therefore, the application range is naturally limited, and it is necessary to prepare a plurality of types of swing links 52 having different dimensions according to the type of the opening width dimension of the door mounting frame A.

る。A feature of the folding door opening / closing guide device according to the first aspect of the present invention is that the height is larger than the opening height on one side in the opening width direction of the door mounting frame. The mounting base end of the bent folding door is swingably opened and closed so as to be extendable along the front surface of the opening, and is provided on one side in the opening height direction of the door mounting frame. A movable body that is guided in the opening width direction along the travel guide groove is provided, and furthermore, the movable body and the front end side of the folding door in a state where the tip of the folding door to be opened and closed does not contact the front surface of the opening of the door mounting frame. And a linking means for linking the opening and closing freely.

影響は少なくなる。According to the above-mentioned characteristic configuration, the movable body guided in the opening width direction along the running guide groove provided on one side in the opening height direction of the door mounting frame and the tip end side of the folding door, Because the opening and closing operation of the folding door is linked via the linking means that guides the opening and closing without touching the front surface of the opening of the door mounting frame, the depth of the door mounting frame is narrow and the opening width is wide. In addition, it is possible to prevent the tip movement trajectory of the folding door to be opened / closed from protruding largely forward, and to move the movable body in the opening width direction even if the opening width of the door mounting frame increases or decreases. This can be dealt with simply by changing the length of the travel guide groove that guides the movement along. In addition, the linking means itself can be made more compact than the swing link 52 of the conventional device, so that the influence of the assembly error of the linking means on the finishing accuracy of the folding door is reduced.
