Abstract

PROBLEM TO BE SOLVED: To provide a shelf board where a reinforcement material never comes off from a hole and a surface of a resin shelf board is made not to have a scratch by fitting the reinforcement material in the resin shelf board of furniture, etc., whose strength is improved by fitting the reinforcement material to a through hole. SOLUTION: The side piece tip of the reinforcement material is bent and formed to form projecting-side piece parts 4, 4 which are prevented from coming off by frictional contact with the partitions 5, 5 of the hole 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf board in which a reinforcing material fitted in a through hole prevents the surface from being scratched.

[0002]

2. Description of the Related Art In many cases, shelves are used for general furniture, and the shelves are supported by being mounted on tabs attached to side plates. That is, this is a simple support structure in which a pilot hole is formed in the side plate of the furniture main body, and tab legs are fitted in the pilot hole to mount both ends of the shelf plate.

Conventionally, the shelves have been made of wood, but recently, resin shelves have come into widespread use, and are advantageous in that they are lighter and more durable than the wooden shelves, and the manufacturing cost is low. Therefore, the resin shelf board has become thinner and slimmer, and as a result, when a heavy object is placed on it, it flexes and deforms significantly without breaking, and both ends come off from the tabs along with the deformation. It will not be able to be stored in the lower tier because it falls or the space between the upper and lower shelves is reduced.

Therefore, a metal reinforcing material may be embedded inside in order to prevent the resin shelf board from bending. FIG. 5 is a specific example showing a conventional shelf support structure, which is flexibly deformed by placing an object on the center of the shelf. (a) is a resin shelf board
When the object (b) is placed on (a), the amount of bending of the shelf plate becomes large. (b) is a resin shelf plate (d) in which a metal reinforcing material (c) is embedded, and the amount of bending is relatively small. The greater the amount of the reinforcing material (c) embedded, the smaller the amount of bending, but the heavier the shelves (d).

FIG. 6 shows a resin shelf board (a) with a metal reinforcing material.
This is the case where (C) is inserted. As shown in (b), the resin shelf board (a) is provided with partitions so that a plurality of holes (f), (f) ... Then, the reinforcing materials (c) and (c) having a U-shaped cross section are fitted into the holes (f) and (f), but the surface is scratched. That is, small convex portions (chi), (chi) ... Are provided on the surface of the reinforcing material (c), and the convex portions (chi), (chi) ...

When the reinforcing material (c) is fitted in the hole (f), it can be fitted relatively easily, and the fitted reinforcing material (c) must be prevented from falling out of the hole (f). I won't. That is, when the resin shelf board (a) is removed,
The convex portion (h) does not fall off by hitting the inner surface of the hole (f), but since it is a small convex portion (h), the friction is small and it does not hinder the insertion. However, it is necessary to prevent the surface of the resin shelf (a) from being raised and scratched.

However, if the size of the convex portion (h) is reduced to such an extent that the surface (g) of the resin shelf board (a) is not scratched, if the size error of the hole (f) increases It means that the reinforcing material (C) that has been inserted into the can not be fixed at the convex portion (H). Therefore, the reinforcing material (c) may be fixed with an adhesive, or a cap may be attached so that the fitted reinforcing material (c) does not fall out, but the cost increases because the number of working steps increases.

[0008]

As described above, the conventional shelf boards have the above-mentioned problems. The problem to be solved by the present invention is this problem. Even if a reinforcing material is fitted into the hole, the surface of the resin shelf plate is prevented from being scratched, but the reinforcing material does not fall out of the hole. Provide the structure of the shelf board.

[0009]

The resin shelf board of the present invention is constructed by fitting a metallic reinforcing material into a through hole formed by a partition in order to suppress the flexure to a small extent. However, in the present invention, the inserted reinforcing material prevents the surface of the resin shelf plate from being scratched, and therefore both side pieces at the tip of the reinforcing material are projected outward. Therefore, the side pieces extending over the partition of the hole hit and generate a frictional force, and the reinforcing material does not fall out of the hole. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0010]

EXAMPLE FIG. 1 is an example showing a reinforcing member for a resin shelf according to the present invention, which has the same basic U-shaped cross section as the conventional one,
It is a long material having a bottom piece 1 and both side pieces 2, 2. Then, as shown in the figure, in the reinforcing material, the corner portions of the side pieces 2 and 2 at the tips are bent outward to increase the width thereof. However, because it is a reinforcing material composed of metal plate material,
The side piece portion that is bent and extended outward is easily bent and deformed.

FIG. 2 shows a case where the reinforcing bar is fitted in the hole 3 of the resin shelf board. The projecting side pieces 4, 4 in which the tip corners of the side pieces 2, 2 are bent hit the partitions 5, 5, and some friction is generated between the partitions 5, 5. Therefore,
The reinforcing material fitted in the hole 3 does not fall out by removing the shelf plate and tilting it. When the projecting side pieces 4 and 4 are brought into frictional contact with the partitions 5 and 5, scratches are generated on the partitions 5 and 5, but there is no problem because it is not the surface of the resin shelf board.

FIG. 3 is another embodiment showing a reinforcing member fitted in the hole of the shelf plate. This reinforcing member has both side pieces 2 and 2 curved outward, but unlike the case shown in FIG. 1 in which the tip corner portion of the side piece is bent, the tip portion of the bottom piece 1 is deleted. Then, the entire side piece of the removed bottom piece is bent outward. Therefore, the projecting side pieces 6 and 6 can be largely projected, and when they are fitted in the holes 3 of the shelf plate, they are appropriately bent and deformed to cause friction with the partitions 5 and 5 to be fixed. .

FIG. 4 shows a case where this reinforcing material is fitted in the hole 3. The tips of the projecting side pieces 6, 6 do not come out of the holes 3 by making line contact with the partitions 5, 5. As described above, in the shelf board of the present invention, the reinforcing material is fitted in the hole formed by the partition, and the protruding side piece portions are formed on both side pieces of the reinforcing material. You can get it.

[0014]

In the present invention, in order to reinforce the resin shelf board,
A metal reinforcing material is fitted in the hole, and a side piece of this reinforcing material is bent to provide a protruding side piece portion. Therefore, this overhanging side piece generates an appropriate frictional force on the partition of the hole,
Even when the shelf is tilted, the reinforcing material does not fall out of the hole. Further, the overhanging side piece is formed by bending the side piece, and it can be flexibly deformed by hitting the partition, and even if there is a large dimensional error in the hole, a reinforcing material can be fitted and the side piece is stable. It can be installed. Even if a scratch is generated by hitting the partition, the scratch does not surface and the appearance of the shelf plate is not damaged.
