Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a floor panel, particularly a floor panel suitable for the floor configuration of a room in which OA equipment is installed.

Conventional technology Conventionally, a rectangular or square floor panel made of synthetic resin and having grooves for wiring electric wires etc. on the bottom surface has been used as a floor panel suitable for the floor configuration of a room where OA equipment is installed. This method is known from Japanese Utility Model Application Publications No. 50-148830 to No. 52-53116.

Problems that the invention aims to solve: However, the floor panel of the conventional structure consists of a plurality of grooves provided on the bottom surface of the thick rectangular floor material, exclusively for guiding electric wires etc. from one side to the other. Since the floor panels themselves do not have any means to absorb unevenness (irregularities on the surface of the floor plate made of concrete, etc.), when the floor surface is composed of floor panels, the floor plate and There was a defect that rattling occurred between the two.

Means for Solving the Problems Therefore, in order to eliminate the above-mentioned conventional defects, the present invention provides a structure in which the lower surface of a flexible rectangular thin plate extends toward the opposite sides of the thin plate, and
Legs are provided on both sides in the longitudinal direction, and a reinforcing part thicker than the thin plate is provided between the legs and has a concave groove for storing the cord, and the reinforcing part is provided with:
A resection part is provided to divide this, and further,
The present invention is characterized in that a number of leg portions having the same thickness as the reinforcing portion are arranged on the lower surface of the thin plate having no reinforcing portion so as to leave gaps therebetween.

Effects However, as in the past, a large number of floor panels
Floor panels are constructed by laying on a floor plate made of concrete etc.
Unevenness can be effectively absorbed by the cutout part provided in the reinforcement part, the gap between the legs, and the flexibility of the thin plate.
The reinforcing portion and the lower surfaces of the legs are in close contact with the floorboard without any play.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

Figure 1 is a back view of the floor panel of the present invention.
is a flexible thin plate made of synthetic resin such as hard polyvinyl chloride (PVC), ABS resin, or polypropylene, and has a square or rectangular shape with a side of 40 to 60 cm.

Reference numeral 2 denotes a reinforcing portion, which is formed at the center of the lower surface of the thin plate 1, extending in a cross shape toward the opposite sides, and having a thickness 3 to 10 times that of the thin plate 1. On each side branching out in all directions from the center of this reinforcing part 2, one or several places are attached to the reinforcing part 2.
A slit-shaped cut portion 3 is provided to divide the reinforcing portion 2 in the middle, and leg portions 4 are protruded from both sides along the longitudinal direction of the reinforcing portion 2, and a recess for storing the cord 7 is provided between the leg portions 4 on both sides. A groove 8 is formed, and this leg 4
, the cutout portion 3 extends at the same position as the reinforcing portion 2.

The reinforcing portion 2 has such strength that it will not be affected in any way even when equipment, desks, chairs, and other furniture are placed on the floor panel or when walking.

5 is also a leg portion, and a large number of leg portions 5 are formed on the lower surface of the thin plate 1. That is, the leg portions 5 are densely formed in large numbers on each lower surface of the thin plate 1, which is divided into quarters by four sides branching from the center of the reinforcing portion 2, so that a gap P is created between them.

The thin plate 1, the reinforcing part 2, and the legs 4, 5 can be integrally molded and can be provided at a very low cost, and preferably a support 6 is provided in the center of the reinforcing part 2.

FIG. 2 is an enlarged sectional view taken along line A-A in FIG. The cord 7, which is thick in height and wired on a floor plate 9 made of concrete, etc., is stored in a groove 8 on the lower surface of the reinforcing part 2, and the upper surface of the thin plate 1 is coated with carpet, tile, PVC, elastic material, etc. A floor finishing material 10 such as flooring is pasted, and equipment is installed or people walk on it.

Note that the tips of the legs 4 and 5 are made of soft PVC.
A layer of soft material such as ethylene-vinyl acetate copolymer, amorphous polypropylene, rubber, etc. may be formed.

The present invention has the above-mentioned structure, and provides a floor that is aesthetically superior and allows office equipment and telephone cords to be stored under the floor.

The present invention is characterized by the flexibility of the thin plate 1, the cutout portion 3 that divides the reinforcing portion 2, and the gap p between the leg portions 5.
As a result, the legs bend in response to unevenness on the floor made of concrete or the like, so that the legs come into close contact with the floor, thereby preventing wobbling due to poor contact between the floor panel and the floor when walking. Further, the reinforcing part 2 together with the legs 4 and 5 supports the load applied to the entire floor panel and is strong.

Furthermore, by forming a layer of soft material such as soft PVC, amorphous polypropylene, ethylene-vinyl acetate polymer, rubber, etc. on the tips of the legs 4 and 5, they can be brought into closer contact with the floor surface.

As described above, the floor panel of the present invention can effectively absorb unevenness on the floor board to form a floor surface without rattling, and can also provide a product with excellent load resistance.
