Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a folding door guiding device for opening and closing an opening of furniture (including built-in furniture).

(Prior art and its problems) This type of folding door has a structure in which the door is unfolded into a continuous plane, such as the folding door described in Japanese Utility Model Publication No. 51-48362 and Japanese Utility Model Application Publication No. 57-6474. There are two types: one type in which the door fits into the opening of the furniture when the opening is closed (hereinafter referred to as an inset type), and the other type in which the door is located outside the opening (hereinafter referred to as an outset type). type).
With the former inset type, there is almost no need to accurately adjust the longitudinal position of the door when the door is closed as described above, but with the latter outset type, when the door is closed as described above, The front-back position of the door determines the gap between the door and the front end surface of the furniture body located above and below the opening, and therefore when the door is closed as described above. If the longitudinal position of the door is not precisely adjusted, the door may come into contact with the front end surface of the furniture body, or an unduly wide gap may be created between the two.

That is, especially in a guide device for guiding an outset type folding door such as the one described above, it is necessary to be able to easily adjust the pivot position of the supported door back and forth when installing the door. Until now, no guide device has been considered that can solve these problems.

On the other hand, in the aforementioned outset type folding door, a support member having a fitting portion for the slide guide rail must be attached to the folding door so as to be swingable around a vertical axis. Once the support member is attached to the folding door, it is normal that the fitting portion of the support member cannot be fitted to the slide guide rail, so the fitting portion of the supporting member cannot be fitted to the slide guide rail. The support member and the folding door must be connected at the same time. However, in the conventional guide device of this type, in order to connect the support member and the folding door with the fitting portion fitted into the slide guide rail, the mounting seat for the folding door is attached to the folding door using a wooden screw or the like. Since it has to be directly fixed to the surface, it is difficult to work with and requires a lot of effort and time.

(Means for Solving the Problems) The present invention has been made to solve the conventional problems as described above, and its features are shown in parentheses with reference numerals in the embodiments described below. As shown, a support member 1 includes a guide member that fits and slides on a slide guide rail attached to the furniture body in the width direction, a movable piece 2 connected to this support member 1, and a movable piece 2 connected to this support member 1. In the case where the support member 1 is provided with a mounting seat 3 that is pivotally supported so as to be swingable back and forth, the support member 1 has a male fitting portion 10 provided on the movable piece 2.
a female fitting part 9 which is fitted so as to be movable in a horizontal direction perpendicular to the slide guide rail, and one fixing screw 17 which fixes the male fitting part 10 to this female fitting part 9. A male fitting part 1 of the movable piece 2 is provided.
0 has a long hole 16 through which the fixing screw 17 passes.
is provided such that one end thereof is open at the tip of the male fitting part 10, and a vertical shaft 13 for pivotally connecting the movable piece 2 and the mounting seat 3 is located outward from the front end surface of the furniture main body. The present invention is characterized in that the end portion of the folding door whose vertical end portion covers the front end surface of the furniture body is attached to the mounting seat 3.

(Function of the invention) In the folding door guide device of the present invention having the above-mentioned features, the mounting seat 3 is attached in advance to the end of the folding door, and the guide member of the support member 1 is moved into a sliding guide. The mounting seat 3 on the folding door side is slidably fitted to the rail.
The male fitting part 10 of the movable piece 2 mounted on the support member 1 is fitted into the female fitting part 9 of the support member 1 so as to be inserted in a horizontal direction perpendicular to the slide guide rail. At this time, the fixing screw 17 of the female fitting part 9
By loosening the fixing screw 17 appropriately, the fixing screw 17 will fit into the elongated hole 16 of the male fitting part 10 from the open part at one end thereof. In this state, the fixing screw 17 is tightened to fix the movable piece 2 and the support member 1 in a fixed direction. By moving the male fitting part 10 in and out in a horizontal direction perpendicular to the slide guide rail, the opening/closing swing fulcrum of the folding door relative to the slide guide rail, that is, the movable piece 2 and the mounting seat 3
It is possible to adjust the position of the vertical shaft 13, which pivots between the two, back and forth.
