Description

[Detailed Description of the Invention] [Industrial Application, Field] The present invention relates to a shelf mounting device used for furniture such as shoe racks and storage units.

[Prior art and its problems]

As shown in Figure 4 (one example)
No.) Reinforcing material 10 is placed on the front and rear edge y of the lower surface of the shelf board 106.
5, and dowels c are installed so as to be located in the front and rear dowel supports 103 on both sides of the recess formed by the reinforcing material 105 and the back surface of the shelf board, and the shelf board is locked.
The shelf mounting device belongs to the known art.

In this prior art, the auxiliary materials provided at the front and rear edges of the shelf have the effect of making the shelf appear thicker and of superior design when viewed from the front. .

However, since the shelf board 101 is supported by the dowel c, the load is applied to the dowel support part 103 of the shelf board 101 itself, so the breaking load of the shelf board 101 is the load limit, and a sufficient shelf thickness is required. This results in high costs.

Furthermore, as in Japanese Utility Model Publication No. 56-839, it has been proposed that one side of the plate-shaped body is folded back, a thick part is provided on the lower surface of the butt end, and dowel grooves are provided in the part other than the thick part. However, in this case, there remains a problem that the minimum cross-sectional area of the shelf board is further reduced due to the presence of the dowel grooves for the reasons described above.

[Means for solving problems and their effects]

In order to solve the above-mentioned problems, the shelf mounting device of the present invention uses a plate-like body 1 as shown in FIG. At the same time, dowel grooves 3 are formed on the front edge x and rear edge y of the front edge y, respectively, on the surface near the butt end in the longitudinal direction. Two V-grooves 4, 4 are each carved so as to leave the sheet-like material 2 on the surface, and the front edge x and the rear edge y are bent and fixed from the V-grooves 4, 4 to the back side for reinforcement. A dowel groove 3 is formed on the back side of the material 5, and a shelf board 6 is formed between the V grooves 4 and 4.
The shelf plate structure A is formed by attaching a dowel c to the shelf mounting part B so as to be located in the dowel groove 3, and fitting the dowel groove 3 into the dowel c.

With the above-mentioned configuration, the shelf mounting device of the present invention can easily form the shelf structure A as a factory-produced product from the plate-like body 1 covered with the sheet-like material 2, and has a high design quality. Even if the thickness of the shelf board 6 of the plate structure A is thinner than that of the prior art, it has the following functions: it can support the same load as the prior art, and it has less deflection.

[Explanation of Examples]

Examples of the present invention will be described below.

First, a sheet-like material 2 such as a paper cloth or a synthetic resin sheet, which has been arbitrarily decorated, is attached to the surface of a plate-like material 1 such as plywood, fiberboard, or wood chip board.

Next, concave grooves 3 are carved in the front and rear edges of the surface of the plate-like body 1 to which the sheet-like material 2 is attached, respectively, in the longitudinal direction.

Further, two V-grooves 4 are carved in each of the back surfaces so that the sheet-like material 2 on the front surface is left over the entire length in the longitudinal direction of the front end edge and the rear end edge of the back surface.

Next, as shown in FIG. 2, while applying adhesive to the inside of the V-groove 4 and the back side of the front edge x and rear edge y separated by the V-groove 4, The part x and the rear edge part y are bent and fixed to form the reinforcing material 5.
shall be. A dowel groove 3 is formed on the back side thereof.

Further, at this time, the shelf board 6 is also formed at the same time by the portion between the V-grooves 4, 4 of the plate-shaped body 1 which is left after being bent together with the reinforcing material 5. Hereinafter, the shelf board 6 and the reinforcing material 5 will be referred to as a shelf board structure A.

On the other hand, the dowel c is attached to the side plate of furniture, the shelf board attachment part B of a mullion, etc.

A groove 3 formed in this dowel c on the back side of the shelf board A
Install while mating.

In this way, the present invention allows the reinforcing members 5 to be easily formed on the front and rear edges of the plate-shaped body 1, and
The load applied to the shelf board structure is supported by the dowel c via "the shelf board 6 plus the thickness of the reinforcing material 5." Therefore, in the prior art, the load applied to the shelf board structure A had to be supported only by the thickness θ of the shelf board 106, but in the present invention, the load applied to the shelf board structure A had to be supported by the "shelf board 6 plus the thickness of the reinforcing material 5". It is sufficient to support it by θ. As a result, the thickness of the shelf board 6 can be made thinner than in the prior art. In addition, since the sheet-like material 2 is connected from the front surface to the back surface, including the butt end, the front and rear edges x and y can be bent in a continuous series of steps to form the reinforcing material 5. can.

Further, since the reinforcing material 5 is provided with the dowel grooves 3, the width of the reinforcing material 5 is wider than that of the prior art. As a result, the width of the portion supporting the load of the shelf board 6 plus the thickness of the reinforcing material 5 applied to the dowel c becomes wider, and the amount of deflection is reduced.

[Effect of idea]

a○ Since the shelf board is constructed by forming a V-groove 4 in a plate-like body 1 to which a sheet-like material 2 is attached and then bending and fixing it, it can be easily obtained as a factory-produced product through a series of steps.

b○ The sheet-like material 2 is formed from the surface to the surface including the end portion, and its design is high.

c○ Since the front end edge and the rear end edge of the plate-shaped body bent from the V-groove 4 over the entire length in the longitudinal direction are overlapped to form the reinforcing member 5, the shelf The thickness of the load-bearing portion of the plate structure can be made thicker and wider than in the prior art, the amount of deflection is reduced, and the strength is improved.

d○ The shelf board structure consists of a shelf board 6 made up of the part between the V grooves 4 of the plate-like body 1, and a front end edge x and a rear end edge y of the plate-like body 1 stacked on the back side of the shelf board 6. Because it is supported by dowels through the reinforcing material 5,
As a composite material of the shelf board 6 and the reinforcing material 5, this breaking load becomes the load limit, and the thickness of the plate-like body can be reduced, resulting in cost reduction.

For example, if a dowel groove is provided in a part of the shelf board that is not thick, as in Utility Model Publication No. 56-839, the thickness of the board itself must be increased.

The present invention has realized the strength characteristics of the shelf board 6 and the reinforcing material 5 as a composite material, and has been able to provide a shelf board with reasonable strength.
