Abstract

PURPOSE: To provide a shelf board which is light and hard and will not bend down resulting from long time burden by making dowel receiving dents in the direction of its width on the front/rear edges of the lower board and inserting a supporting crosspiece as wide as the width of the board into at least one hollow. CONSTITUTION: The outer hull plate x is made up of an upper board 1, a lower board 2, and front/rear side boards 3. Inside the outer hull plate x, the upper board 1 and the lower board 2 are connected with ribs r and several hollows h are formed in the direction of the width of the plate. And dowel receiving dents are formed between ribs in the direction of the width of the shelf board made of a synthetic resin at the front/rear edges of the lower board 2. The dowel receiving dents are fixed to the dowels to be attached to the storage furniture. And a supporting crosspiece 5 as wide as the shelf board is inserted to at least one hollow h. The shape of the section of the supporting crosspiece 5 to be used is the same as that of the hollow h, such as pure or pipe-like squire, triangle, circle, or H-shaped, I-shaped, L-shaped, U-shaped, etc.

Description

Detailed Description of the Invention

[0001]

[Industrial application] The present invention relates to a shelf board made of synthetic resin in storage equipment such as furniture, kitchen equipment, and vanity.

[0002]

2. Description of the Related Art Conventionally, as a shelf board in storage equipment, solid wood, plywood, fiber board, particle board and the like have been used. If necessary, a decorative sheet such as a decorative paper sheet or a synthetic resin sheet for decorative sheet is attached to these shelves.
However, since these shelves are made of wood, they are expensive. It also has the drawback of being heavy.

For this reason, in recent years, there has been provided a synthetic resin shelf plate having a plurality of hollow holes defined therein by ribs. The shelf board provided has the advantages that it has hollow holes, is light in weight, and is inexpensive. However, since it is made of synthetic resin, there is a problem that bending and bending progresses with the lapse of a long-term load, and the shelf plate eventually falls off the dowel. If the shelf plate itself is thick and the resin thickness is thick, the above problems can be solved, but the price is high and the weight is heavy.

[0004]

[Technical Means] An outer shell x formed of an upper plate 1, a lower plate 2 and a side plate 3, and an upper shell 1 and a lower plate 2 are connected by a rib r to form a hollow resin h with a hollow hole h. In the shelf board, a synthetic resin shelf board in which dowel receiving recesses 4 are formed at the front and rear edges of the lower plate 2 in the width direction thereof, and at least one hollow hole h is fitted with a reinforcing bar 5 extending over the shelf board width.

[0005]

[Description of Configuration] In a shelf board made of synthetic resin, an outer shell x is formed by an upper plate 1, a lower plate 2, and front and rear side plates 3. In the outer shell x, the upper plate 1 and the lower plate 2 are connected by ribs r, and a plurality of hollow holes h are formed in the width direction thereof. Further, on the front and rear edges of the lower plate 2, there are formed dowel receiving recesses 5 between the pair of ribs r and r and across the width direction of the synthetic resin shelf plate. Since the dowel receiving concave portion 5 is formed in the width direction, the dowel receiving concave portion 5 appears at the end of the wood mouth even if it is arbitrarily cut, and it is not necessary to form a new dowel receiving concave portion after cutting.

When installing in the storage facility, the dowel receiving recess 5 may be fitted and mounted on the dowel attached to the storage facility.
Generally, even a shelf plate made of synthetic resin that easily slips does not slip off. The synthetic resin shelf plate is obtained as a long plate material by extrusion molding of a synthetic resin such as polyvinyl chloride, acrylic, polycarbonate, polyethylene terephthalate, ABS or the like, and is cut into a desired width.

The upper plate 1 and the lower plate 2 are provided with a plurality of thin grooves for preventing slipping. The plurality of thin grooves provided on the upper plate 1 prevent slippage when an article is placed, and the plurality of thin grooves provided on the lower plate are attachment of a synthetic resin shelf plate to storage equipment,
It works as an anti-slip from the hand when removing.

Further, a back guard composed of a rising edge may be provided on the rear edge of the upper plate 1 to prevent falling. The synthetic resin shelf board may be subjected to color coating, pattern pattern printing, or a decorative paper or a decorative synthetic resin film may be attached, if necessary.

The synthetic resin shelf board has at least one hollow hole h in which a reinforcing bar 5 extending over the shelf width is fitted. The reinforcing bar 5 is provided so that its cross-sectional shape matches the cross-sectional shape of the hollow hole h. Its cross-sectional shape is solid, pipe-shaped, square, triangular, round, or H-shaped, I-shaped, L-shaped.
Shapes, U-shapes, U-shapes and the like are used. 2a, b,
Some examples are shown in c and d.

The cross-sectional shape of the reinforcing bar 5 is square, H-shaped, I
Shaped, L-shaped, U-shaped, and U-shaped hollow holes h have a quadrangular cross-sectional shape, and the reinforcing bars 5 have a triangular cross-sectional shape, and L-shaped ones have a corresponding hollow-hole h cross-sectional shape. The hollow hole corresponding to the reinforcing cross-section having a round cross-section has a round cross-section. Only the hollow holes h into which the reinforcing bars 5 are fitted may be different in cross-sectional shape from other hollow holes, or all the hollow holes h may be the same.

As shown in FIG. 3, the reinforcing bar 5 is provided on the surface of the hollow hole h which is in contact with the inner wall surface on a line parallel to the longitudinal direction of the outer surface thereof.
It is also possible to provide one or more protrusions 5a. The protrusion 5a of the reinforcing bar 5 increases the outer dimension of the reinforcing bar 5 itself, and when it is fitted into the hollow hole h, it is fitted so as to press the inner wall of the hollow hole h, so that the repulsive force of the synthetic resin shelf board itself. After it is inserted, it becomes difficult to remove it, and it serves as a stopper.

If desired, a plurality of reinforcing bars may be fitted into the plurality of hollow holes. Reinforcing bars are steel, stainless steel,
It is obtained by using a metal material such as aluminum. In this way, a synthetic resin shelf board was obtained.

[0013]

EFFECTS OF THE INVENTION By inserting a reinforcing bar into at least one of the hollow holes of a synthetic resin shelf having a hollow hole, the shelf board becomes lightweight and has high rigidity, and bending flexure does not occur due to long-term load. Becomes
