Description

[Detailed Description of the Invention] The present invention relates to the structure of folded parts of furniture doors, fittings, etc.

BACKGROUND ART Conventionally, the bending portion of a wooden product is made freely bendable by connecting two members using a metal hinge.

In such a case, in order to achieve the desired state before and after bending, it is necessary to attach the hinge at a predetermined and accurate position. In addition, for folded parts that require multiple hinges, the axes of the rotation axes of all hinges must be perfectly aligned in order for the connected members to rotate smoothly, which requires more precise machining. .

Furthermore, in the folded parts of ornaments that require an aesthetic appearance, the hinge is often attached on the inside where it cannot be seen, and in order to make both connected members in close contact on the side where the hinge is attached, the thickness of the hinge must be adjusted. It is necessary to install the hinge by recessing the hinge, making it more difficult to align the axes of the rotating shafts of the hinges, and the installation requires the skill of the operator and a considerable amount of time.

The present invention was developed in view of the above circumstances, and there is no need to completely align the axes of the hinges as in the past. Some errors can be tolerated, the process can be completed in a short time, and it does not block vision etc. It is an object of the present invention to provide a structure for folding parts of furniture, etc., which is superior in quality and allows the product to be provided in large quantities at low cost.

Hereinafter, the present invention will be described in detail according to embodiments shown in the drawings.

FIG. 1 is a cross-sectional view of one embodiment.
3 is an object to be bent that requires bending, and in this example, it is made of wood-based material such as wood board, plywood, particle board, hardboard, etc., and 3 is:
This is an intermediate material interposed between the left and right bent bodies 1 and 2, and is made of the same material as the bent bodies 1 and 2.

4 is a strong and flexible sheet made of woven or nonwoven fabric made of nylon, polyester synthetic fiber, etc., which is attached to the back surfaces of the bent bodies 1 and 2 and the intermediate material 3; be.

Grooves 5 and 6 having a V-shaped cross section are formed between the edges of the objects 1 and 2 to be bent and both edges of the intermediate material 3, and grooves 5 and 6 are formed between the objects 1 and 2 to be bent and the intermediate material 3. Only the flexible sheet 4 exists between the grooves 5 and 6, that is, at the groove bottom portions of the grooves 5 and 6. Thus, the objects 1 and 2 to be bent can be bent so that the grooves 5 and 6 are closed or opened.

Next, in order to explain in more detail the structure of the folded portion according to the present invention, a leg member using the above embodiment will be explained in detail based on FIGS. 2 to 6.

7 and 8 are bent portions using the above embodiment.

As shown in FIGS. 2 and 4, the bent portion 7 is formed by the bent bodies 1, 2 and the intermediate member 3 forming the leg portion of the main leg member A, Connecting members 9 and 10 that connect to other folded portions are fixed to the back surface of the flexible sheet 4. That is, the bent body 1,
2 is fixed.

The length X of the inner side 3a of the intermediate material 3 is
The connecting members 9 and 10 are configured to have a thickness that is twice or more than the thickness Y in the planar cross section of the intermediate member 3 side ends.

As shown in FIG. 3, when the objects 1 and 2 to be bent are bent and the flexible sheet 4 is bent, the connecting members 9 and 10 come into contact with each other, and the imaginary line in FIG. They can be made substantially parallel as shown in .

The other bent portion 8 is also configured in the same manner as the bent portion 7, but in a state in which the bent objects 1 and 2 are not bent and the flexible sheet 4 is stretched linearly. The objects to be bent 1 and 2 are bent as shown in FIG.
edges 1a, 2a and both edges 3b, 3c of the intermediate material 3
The structure is such that they are in close contact with each other.

In addition, instead of the bent portion 7, as shown in FIG. 6, the intermediate material 3' has a substantially trapezoidal cross-sectional shape, and the wedge angle β of both oblique sides 3'b and 3'c of the intermediate material 3' is
is configured so that it is almost the same as the angle α formed by the longitudinal axes of the objects to be bent 1' and 2', and the edges of the objects to be bent 1' and 2' and both hypotenuses of the intermediate material 3'3'b,3'
If the grooves 1' and 2' are configured to be in close contact with each other when the grooves are closed and the bent bodies 1' and 2' are expanded, the bent portion 7' can be fixed at a predetermined position in the expanded state. . This not only eliminates the need for a stopper or the like to determine the angle of the bent portion, but also has a great effect in increasing the rigidity of the bent portion.

Note that the flexible sheet 4 and the objects to be bent 1, 2, etc. may be bonded together by, for example, impregnating the flexible sheet 4 with a hot-melt adhesive and heating the impregnated hot-melt adhesive. Either by melting it and adhering it to the objects to be bent 1, 2, etc., or by layering a film-like hot melt adhesive between the flexible sheet 4 and the objects to be bent 1, 2, etc. There is a method of bonding by heating and melting an adhesive.

Since the present invention is configured as described above,
It is not necessary to align the axes of the hinges perfectly as in the past, and some errors can be tolerated, making it extremely easy to attach to bent parts of furniture and fittings, and as mentioned above, it is easy to manufacture bent parts. It can also be carried out in an extremely short period of time, and final products can be provided in large quantities and at low cost through assembly line operations.

Furthermore, when folded, it is compact and has a beautiful appearance. Furthermore, the strength is dramatically improved compared to the case of using conventional hinges, and since there is a flexible sheet in the folded part, it has excellent visual shielding properties.
Its fields of use are extremely wide.

The present invention has various excellent effects as described above.
