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 5 (one example, Utsukō 60-8758
As shown in No.), auxiliary material 102 is placed on the front and rear edge of the lower surface of the shelf board 101.
A shelf board locking device that locks the shelf board by attaching the dowels 104 to the dowel supports 103 on both sides of the recess formed by the auxiliary material 102 and the back surface of the shelf board 101 is known.

In this prior art, the auxiliary material provided at the front and rear edge of the shelf mainly makes the shelf appear thicker when viewed from the front.
This has the effect of making it superior in terms of design.

However, since the shelf board 101 is supported by the dowels 104, the load is transferred to the dowel support part 10 of the shelf board 101 itself.
3, the breaking load of the shelf board 101 is the load limit, and a sufficient thickness of the shelf board is required, resulting in high cost.

Further, the auxiliary material 102 is for preventing the shelf board from moving, and is not particularly for reinforcing the strength of the shelf board.

[Means for solving problems and their effects]

In order to solve the above problems, the shelf mounting device of the present invention has a reinforcing material 2 attached to the front and rear edges of the back surface of the shelf 1 over the entire length thereof, and
A dowel locking groove 3 is formed at the tip of each of the reinforcing members 2, and a dowel 4 is attached to the shelf board mounting part so as to be located in the dowel locking groove 3, and the dowel 4 is fitted with the dowel locking groove 3.
The shelf board structure A is locked by fitting.

By adopting the above configuration, the present invention reduces the weight of the shelf board to the shelf board structure A consisting of the shelf board 1 and the reinforcing material 2.
The reinforcing material 2 is attached to the dowel 4 through the dowel 4, and even if the shelf board 1 is made thin, the thickness of the thin shelf board 1 is reinforced by the entire thickness of the reinforcing material 2. As a result, the thickness of the shelf board 1 can be made thinner than in the prior art, and the deflection thereof is also reduced even if the thickness of the shelf board 1 is thin.

[Description of Examples]

As shown in FIGS. 2 and 3, the shelf board used in the device of the present invention is first made by attaching a reinforcing material 2 to the front and rear edge of the back surface of the shelf board 1 along its entire length with adhesive, nails, etc. Secure with screws etc. to form shelf board structure A.

The reinforcing material 2 has a dowel locking groove 3 at the tip of one side.
is formed, and the opposite side of the dowel locking groove 3 is the shelf plate 1.
It is fixed so that it is in contact with the back side of the

As shown in FIG. 3, the shelf board 1 may have its surface including the wood end painted or covered with a sheet 5, and as shown in FIG. After fixing and constructing the shelf board structure A, a sheet pasting 6 may be applied from the front surface of the shelf board 1 to a part of the back surface so as to cover the end portions of each of the shelves.

The shelf board 1 and the reinforcing material 2 are generally made of wood-based materials such as plywood and fiberboard.

The shelf board structure A constructed in this way has dowels 4 in the shelf mounting part B of the side panels of furniture, mullions, etc.
After installing the dowel 4, the dowel locking groove 3 formed in the reinforcing material 2 on the back surface of the shelf board 1 is fitted into the dowel 4.

In the shelf mounting device of the present invention, the weight of the shelf 1 and the objects placed thereon is applied to the dowel 4 through the thickness of the shelf 1 plus the thickness of the reinforcing material 2. In contrast, in the conventional technique shown in FIG. 5, the weight of the shelf board 101 is applied to the dowel 104 only through the thickness of the shelf board 101. Therefore, "thickness of reinforcing material 2 + thickness of shelf board 1" shown in FIG.
Assuming that θ is the shelf board 10 in the conventional technique shown in FIG.
If the thickness of 1 is equal to θ, it will not be possible to support an equal weight. Therefore, as a result, the thickness of the shelf board 1 of the present invention can be made thinner than that of the prior art.

[Effects of this invention]

a○ Since the shelf board 1 is supported by the dowel 4 through the reinforcing material 2, the breaking load of the composite material of the shelf board 1 and the reinforcing material 2 becomes the load limit, and the thickness of the shelf board cannot be changed to the conventional one. It can be made thinner than others, resulting in cost reduction.

b○ Since the reinforcing material 2 is attached to the front edge and the rear edge of the back surface of the shelf board 1 over the entire length in the longitudinal direction, the reinforcing strength of the reinforcing material 2 is increased compared to the prior art. As a result, the thickness of the supporting portion of the dowel 4 becomes thicker, so that the shelf board 1 bends less than the conventional one.

That is, in the present invention, the reinforcing material 2 is made of a material with a width and thickness sufficient to reduce the deflection of the shelf board 1, and is provided over the entire length of the shelf board 1 in the longitudinal direction. The starting point for the idea was the realization that a shelf board with reasonable strength could be obtained by supporting it with dowels.
