[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which a horizontally rotating door is attached to an opening edge of furniture or the like by a hinge, and the hinge is fastened to an opening edge of furniture or the like by screwing.

[0002]

2. Description of the Related Art As described in, for example, Japanese Utility Model Publication No. 56-24478 and Japanese Utility Model Publication No. 60-6133,
When a door is attached to a furniture such as a cabinet so as to be horizontally rotatable with respect to a main body, a hinge is screwed to a stile of the furniture (when the hinge is composed of a fixed hinge and a movable hinge). Is to screw the fixed hinge to the stile).

[0003]

Incidentally, since the door is repeatedly opened and closed, an impact repeatedly acts on the hinge. For this reason, there is a problem that the screws loosen and fall off due to the vibration, and the hinge may fall off the main body and the door may come off. The present invention aims to solve this problem with a very simple structure.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method for manufacturing a furniture, comprising:
This is a structure in which a plate-shaped hinge for mounting a door so as to be horizontally rotatable is fastened by screwing, wherein an opening edge of the furniture or the like is formed of a metal plate, and a length in which the hinge is inserted into the opening edge. At least two front and rear holding pieces provided with holes and a mounting piece on which a hinge overlaps are provided, and the long hole is set to a size that holds the fixed hinge so that it cannot be displaced in the vertical and horizontal directions. On the other hand, an engaging portion having a forward end surface such as a notch or a square hole is formed in a portion of the hinge overlapping the mounting piece, and the hinge is engaged with the mounting piece. The locking piece that hits the front end face of the portion is cut and raised to form a ".

[0005] In this case, the locking piece is raised and deformed in advance so as to extend obliquely in a side view, and as the hinge is inserted into the elongated hole of the opening edge, the locking piece resists elasticity. Alternatively, it may be engaged with the engaging portion of the hinge. Alternatively, after the hinge is inserted into the long hole of the stile portion, the locking piece may be bent and raised by a suitable tool such as a driver to lock the locking piece to the engaging portion.

[0006]

With this construction, the hinge is held by the front and rear holding pieces so as not to be displaced in the vertical and horizontal directions, and is held by the locking pieces so as not to be displaced forward. The hinge does not come off from furniture or the like even if the screw comes loose due to vibration or the like. In this case, the fixing hinge has a very simple configuration in which an engaging portion such as a notch is formed while the mounting piece is cut and raised, so that the structure is not complicated.

Therefore, although the structure is very simple, it is possible to reliably prevent the hinge from coming off and the door from coming out,
It has the effect of improving safety. In addition, if the locking piece is raised and deformed in advance, the hinge is temporarily fixed by inserting the hinge into the long hole of the opening edge. Therefore, there is an advantage that the work of attaching the door can be easily performed.

[0008]

Next, an embodiment in which the present invention is applied to a cabinet will be described with reference to the drawings. 1 to 4
Is a first embodiment, of which FIG. 1 is a partial perspective view of a steel cabinet, FIG. 2 is a partially cutaway plan view of FIG.
3 is an exploded perspective view, and FIG. 4 is a sectional view taken along line IV-IV in FIG.

The cabinet has a main body 1 and a door 2, and a metal plate fixing hinge 4 is attached and fixed to an upper and lower stile portion 3 constituting an opening edge of the main body 1 so as to be partially exposed. The door 2 is fixed to a movable hinge 6 pivotally connected to a hinge 4 with a pin 5. The details will be described below. Note that the upper and lower stile portions 3 have the same structure, and in the following description, the mounting structure of the fixed hinge 4 to the upper stile portion 3 will be described.

The top edge of the top plate 7 of the main body 1 is folded downward to form a rectangular tube. Thus, the stile portion 3 is formed.
The reinforcing member 8 includes a first holding piece 8a overlapping the downwardly bent piece 7a of the top plate 7, and a vertical second holding piece located behind the first holding piece 8a.
8b and a third holding piece 8c, and a horizontal mounting piece 8d connected to the lower ends of the second and third holding pieces 8b and 8c.

An elongated hole 12 into which the insertion portion 4a of the fixed hinge 4 is inserted from the front of the cabinet is formed in the downwardly bent piece 7a of the top plate 7 and each of the holding pieces 8a, 8b, 8c of the reinforcing member 8. ing. The long hole 12 is set to have such a size that the fixed hinge 4 is held so as not to be displaced in the left-right direction and the up-down direction. The exposed portion 4b of the fixed hinge 4 is formed wider than the insertion portion 4a, and a pair of left and right portions at the base of the insertion portion 4a in the exposed portion 4b so that the exposed portion 4a is in close contact with the front surface of the main body 1. The recess 13 is cut out.

The mounting piece 8d of the reinforcing member 8 is set so as to be in close contact with the insertion portion 4a of the fixed hinge 4. A screw 15 is inserted from below into a hole 14 formed in the mounting piece 8d, and this is inserted. The fixed hinge 4 is fastened to the reinforcing member 8 by being screwed into the screw hole 16 of the fixed hinge 4. A pair of left and right notches 17 is formed as an example of an engaging portion on the left and right side edges of the insertion portion 4a of the fixed hinge 4, while the fitting piece 8d of the reinforcing member 8 fits into one of the notches 17. The locking piece 18 is cut and raised so as to extend obliquely upward toward the rear, and the locking piece 18 is brought into contact with the front end face 17 a of the notch 17.

The pair of left and right notches 17 is formed in the fixed hinge 4 in spite of the fact that only one locking piece 18 is formed. This is because it is also used as a left-opening door. Naturally, a pair of locking pieces 18 may be formed, or the notches 17 may be formed at only two places. In the above configuration, with the fixed hinge 4 attached to the door 2, the insertion portion 4 a of the fixed hinge 4 is
After inserting into each long hole 12 of stile part 3 against the elasticity of
By fastening the fixed hinge 4 to the reinforcing member 8 with the screw 15, the door 2 can be attached to the main body 1 so as to be horizontally rotatable.

The insertion portion 4a of the fixed hinge 4 is
Is held irreversibly in the left-right direction and the up-down direction, and is held undetachably by the locking piece 18. Therefore, even if the screw 15 comes off due to vibration or the like during use, the fixed hinge 4 is It is possible to prevent an unexpected situation in which the door 2 comes off and the door 2 comes off. Further, if the locking piece 18 is raised and formed in advance as in the embodiment, even if the fixed hinge 4 is still attached to the door 2, the fixed hinge 4
By inserting the insertion portion 4a into the elongated hole 12, the fixing hinge 4 is irremovably held by the locking piece 18, in other words, the fixing hinge 4 is temporarily fixed to the shackle portion 3 by the locking piece 18. Therefore, the work of attaching the door 2 becomes easy. Instead of raising and forming the locking piece 18 in advance, the insertion piece 4a of the fixed hinge 4 may be inserted into the elongated hole 12, and then the locking piece 18 may be pushed up from below with a driver or the like to be raised and deformed.

In the above embodiment, the notch 17 is formed as the engaging portion. However, as the engaging portion, FIG.
It may be a square hole 19 as shown in the embodiment.
