Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shelf board made of bent plate material.

[Prior art and its problems]

Shelf boards, especially the shelves installed in the middle of the closet,
A stile was placed between the front pillars of the closet, a support material was placed between the back pillars, and a plurality of joists were placed between the stile and the support materials, and then the board material was placed and fixed.

However, this construction method has the problem that the stile, support material, and joist must be laid each time, making the construction complicated and time-consuming.

In order to solve these problems, the present applicant previously proposed a shelf board in which one end of a board is bent to form a frame part for the purpose of simplifying construction.

The construction method for this shelf is to attach a support material between the rear pillars of the closet, then place the rear part of the shelf on the support material, and then attach the frame of the shelf to the back of the front pillar and fix it. It is something.

Although this proposed construction method has achieved its purpose in simplifying construction time, it still has the following problems in terms of strength and cost.

In other words, since the shelf board is made by bending one end of the plate material to form a frame part, the strength of the shelf board must be maintained at the frame part, and the thickness of the board itself must be increased.
The flat part of the shelf board is thicker than necessary,
This has the drawbacks of increased weight and increased price.

[Means for solving problems and their effects]

In order to solve the above-mentioned problems, the shelf board of the present invention is made by forming a plurality of bending grooves 2 on the back side of the end of the board 1 so as to leave a part of the board 1, and then forming a part on the back side of the board 1 from the bending grooves 2. In a shelf board having a bent frame part 5, a reinforcing plate 6 having a shape that matches the back surface of the bent part is fixed to the back side of the frame part 5 of the shelf board.

[Description of the first embodiment] First, the first embodiment will be explained with reference to FIGS. 1 and 2.

As shown in FIG. 1, first, a plurality of bending grooves 2 are formed on the back side of the end of the substrate 1 so that a portion of the substrate remains, and a comb pattern is applied. In this case, the substrate 1 may be made of plywood, fiberboard, particle board, or the like, and the bending grooves 2 are formed on the back surface of the end thereof using a processing machine such as a multi-axis running saw.

The bending groove 2 is a part of the substrate 1, preferably 0.5~
Form so as to leave a thickness of about 5 mm.

If the remaining thickness is less than 0.5 mm, the strength will be low and the remaining base material will easily tear when folded, and if it is 5 mm or more, the strength will be high and it will easily break when folded.

Next, as shown in Fig. 2, the bending groove 2 is filled with adhesive, bent around the groove 2 to the back side, held and fixed at a predetermined holding point, the adhesive is solidified, and the curved surface is processed.
A bent portion 3 is formed.

In this way, a plate material was obtained in which the four ends of the flat part were curved to form a frame part.

A reinforcing plate 6 whose tip is processed to match the bent shape of the back surface of the plate material is attached to the back side of the frame portion 5 of the plate material via an adhesive.

In this way, the shelf board of the present invention is obtained.

Further, as shown in FIGS. 3 and 4, reinforcing members 7 for connecting the reinforcing plate 6 and the back surface of the shelf flat portion 4 are attached to the shelf board as necessary.

The reinforcing material 7 is made of synthetic resin or metal, L-shaped as shown in Fig. 3, V-shaped as shown in Fig. 4, etc.
Attach using adhesive, nails, screws, etc.

The surface of the shelf board may be improved by pasting a sheet-like material such as decorative paper or decorative PVC sheet over the entire surface thereof, or by applying a colored coating.

[Description of Second Embodiment] The second embodiment shows a modification of the present invention.

As shown in FIGS. 5 and 6, the bent portion 3 of the plate material of the present invention is formed by forming a V-groove 8 on the back surface of the end of the substrate 1, applying adhesive, and bending the plate material around the V-groove 8 on the back surface. It may also be a plate material with a frame portion 5 formed thereon as shown in FIGS. 2 to 4.

[Description of Third Embodiment] The third embodiment shows a modification of the present invention.

7 and 8, two V grooves 9, 9 are provided instead of the V groove 8 in the second embodiment, and the corner portion is formed on the inclined surface 3a.
A bent portion 3 is provided.

[Effect of idea]

One end of the substrate 1 is bent to form a frame portion 5, and a reinforcing plate 6 having a shape that matches the back surface of the bent portion is provided on the back surface of the frame portion 5.
, and the reinforcing material 7 is fixed as necessary, so the strength of the shelf board is increased by the board 1, the reinforcing plate 6, and the reinforcing material 7.
The substrate 1 itself needs only the minimum necessary thickness, is light in weight, and is inexpensive. That is, in the present invention, since the reinforcing plate 6 is brought into close contact with the back surface of the bent portion so as to match the shape thereof, the opening of the bending groove 2 is closed, the reinforcing plate 6 and the bent portion of the shelf plate are integrated, and both If this is done, the bent portion, which has reduced strength, will become a stable structure.
