Description

[Detailed Description of the Invention] This invention relates to a folding door device applied to cabinets and the like.

Conventionally, a cabinet equipped with a folding door device as shown in FIG. 1 has been used.

In the figure, 1 is a cabinet body, and two unit doors 2 and 3 are foldably connected to each other through the front opening of the cabinet body (1).
- Two sets of folding doors 4.5 are arranged side by side.

These folding doors 4, 5 have one end 4a, 5a rotatably supported on the side plate of the cabinet body 1, and the other end 4b, 5b.
is movably locked along a slide rail 6 provided at the upper edge of the opening of the cabinet body 1.

In such a folding door device, as shown in FIG.
There may be a difference in level t in front and behind each other.

Therefore, conventionally, a pair of correction fittings 7.8 shown in FIG.

5b, facing each other.

Each of the correction fittings 7, 8 includes mounting plate portions 7a, 8a fixed to the front or back surface of the folding door 4, 50, and the mounting plate portion 7a,
It has engaging tongue pieces 7b and 8b extending from 8a.

When these engaging tongues 7b, 8b come into contact with the surfaces of the mounting plate portions 7a, 8a of the corresponding correction fittings 7, 8, the difference in level t between the front and rear of the double-folding doors 4, 5 is corrected.

However, as shown in Fig. 4, the moving end 4 of the double folding doors 4 and 5
It was not possible to correct the level difference m that occurs in the vertical direction in b and 5b.

Therefore, an object of this invention is to provide a folding door device that can correct the level difference in both the front and rear direction and the vertical direction at the moving end of the folding door.

An embodiment of this invention is shown in FIGS. 6 to 8.

That is, in this folding door device, one of the correction fittings 10 attached to the movable ends 4b and 5b of both folding doors 4.5 is provided with one engaging tongue piece 10b extending from the mounting plate portion 10a, and the other The correction fitting 11 is provided with two engaging tongues 11b and 11c extending in a hawk shape from the mounting plate portion 11a and engaging with the one engaging tongue 10b.

These engaging tongues 10b, 11b, 11c are bent in an S-shape at the base end, extend parallel to the mounting plate parts 10a, 11a, and are buttoned, respectively. It abuts on the surface of 11a.

Furthermore, a warped portion is provided at the tip of each of the engaging tongues 10b, 11b, and 11c.

The mounting plate portions 10a, 11a have long mounting holes 12,
The folding door 4,
It is fixed at 5.

Due to this structure, when the double folding doors 4.5 are closed, the engaging tongues 10b, 11b, llc of the correction fittings 10° 11 of the double folding doors 4, 5 engage with each other in the vertical direction, These engaging tongue pieces 10b, 1lb, 11
Mounting plate part 10a of correction fitting 10°11 corresponding to c,
It abuts on the surface of 11a.

Therefore, the difference in level between the moving ends 4b and 5b of the double-folding doors 4 and 5 in both the vertical direction and the front-back direction is t.

m (Figs. 3 and 4) can be corrected, and accurate opening and closing can be performed.

As described above, the folding door device of this invention has one correction fitting provided at each of the moving ends of a pair of folding doors.
In addition to providing an engaging tongue for the book, two retaining tongues extending in a hawk shape to the other correction fitting and engaging with the one retaining tongue are provided, and each of these retaining tongues corresponds to a corresponding one. Since the correction fitting is configured to come into contact with the surface of the mounting plate portion of the double-folding door, it is possible to correct the level difference in both the vertical direction and the front-back direction of the moving end of the double-folding door, and accurate opening and closing can be performed.
