Abstract

PURPOSE:To adjust the height of the leg of a floor material when the cable, etc., of an OA equipment are disposed into a space on the rear of a top face board by forming the floor material from the top face board and a plurality of legs mounted on the rear of the top face board. CONSTITUTION:Bearing legs 5 on the insides of legs 3 have screw structure, are moved vertically in the legs 3 and can be projected and retreated from the front ends of the legs 3. The head sections of the bearing legs 5 are formed in a polygon, and the corner sections of a top face board 2 are bored and the height of the legs 3 is adjusted from an upper section. The surface of the top face board 2 is covered smoothly with caps 8 in conformity with the head section of the external shape of the polygon. Consequently, the shake of the bearing legs 5 by the walk of a man and the revolution of the bearing legs 5 are prevented. The comer positions of the head sections of the bearing legs 5 and the corner positions of the polygon mounted on the top face board 2 are matched by putting register marks, etc., and the caps 8 are fitted accurately. Accordingly, the height of the top faces of floor materials 1 can be conformed easily even when the height of the legs 3 is adjusted and the floor materials 1 are spread all over a concrete floor face, etc., having waviness.

Description

Detailed Description of the Invention

[0001]

This invention relates to floor coverings. More specifically, the present invention relates to a flooring material that is used when wiring a cable or the like of an OA device to the floor and has a rear surface side of the upper surface plate as a wiring space and its periphery supported by legs.

[0002]

2. Description of the Related Art With the development of OA equipment, OA has been installed in offices.
Equipment has been installed more often. Installation of OA equipment requires wiring such as a power cable and a communication cable in the room. For this reason, it has been common to lay a cable directly on the floor surface or attach a long plastic cable guide to the floor surface and pass the cable through it, but the structure projects from the floor surface. There were inconveniences such as hindering walking and kicking off the cable.

For this reason, in recent years, a floor material (generally referred to as a free access floor, double floor, etc.) having legs on the lower surface of a quadrangular plate is prepared, and the floor material is laid on the floor. The space on the back surface of the plate-shaped body is used as a wiring space for cables and the like.

[0004]

Generally, the above-mentioned floor material is made of a synthetic resin in which legs having a predetermined height are provided at required points such as the corners of the back surface of the top plate. However, these floor materials generally have a structure in which synthetic resin is integrally molded by injection molding or the like, and the height of the legs is constant.

Usually, this type of flooring material is used by laying it on a concrete floor or the like, but the entire surface of the concrete floor cannot be said to be uniform and horizontal, and there are irregularities on the surface and steps on the seams of the floor. Exists. In the case of the surface of a concrete floor, the surface becomes uneven so that it is not noticeable even if you look directly at it, but if you spread the above floor material on it, there will be a step or a part of the floor material Will be raised and rattled.

It is conceivable that the legs of the flooring material may be shaved to adjust the height, or the plate material may be sandwiched under the legs, but it is difficult to work and is not practical.

DISCLOSURE OF THE INVENTION In view of the above-mentioned problems, the inventors of the present invention have made extensive studies, and as a result, have found that the problems can be solved by making the legs of the flooring material have a special structure. Heading, completed the present invention. The gist of the present invention is a flooring material comprising a top plate and a plurality of legs provided on the back surface of the top plate, wherein the height of the legs is adjustable. .

Hereinafter, the details will be described with reference to the drawings.
FIG. 1 is a perspective view of an example of the flooring material of the present invention, showing a part of the flooring material in a rolled state. FIG. 2 is a vertical cross-sectional view of an example of the legs of the flooring material of the present invention. In the figure, 1 is a floor material, 2 is a top plate,
3 is a leg, 4 is a rib, 5 is a supporting leg, 6 is a supporting leg head, 7 is a female screw part, 8 is a cap, 9 is a cable guide, and 10 is a cable.

The flooring material 1 of the present invention is generally made by injection molding a synthetic resin, and includes an upper surface plate 2 reinforced by ribs 4 and the like, four corners of the rear surface of the upper surface plate 2 and a corner. For example, it has a structure in which the rectangular tube-shaped leg 3 is provided at a required position. The flooring material 1 of the present invention is laid on a concrete floor surface as shown in FIG. 1, and the cable guide 9 and the cable 1 are provided on the lower surface thereof.
0 is laid.

A specific example of the structure for adjusting the height of the leg 3 will be described. A support leg 5 is provided inside the leg 3,
The support leg 5 can move up and down in the leg 3 by a screw structure, and is adapted to come in and go out from the tip of the leg 3. More specifically, when the floor material 1 is injection-molded, a metal member having a female screw portion 7 is held in a mold part corresponding to the leg 3, and then injection molding is performed to fix the female screw portion 7 in the leg 3 inside. Buried in. The height of the leg 3 can be adjusted by screwing the support leg 5 made of metal or the like having a male screw portion that matches the female screw portion 7.

The head 6 of the support leg 5 is a polygonal head such as a hexagon, an octagon, etc., and an opening is provided at the corner of the top plate 2.
It is preferable that the height of the leg 3 (the amount of protrusion of the support leg 3) can be adjusted from the side of the upper plate 2. By doing so, it is possible to make adjustments while observing the height of the surrounding floor material from the side of the top plate 2 during construction. The head 6 of the support leg 5 is preferably polygonal as described above, and the surface of the top plate 2 is smoothed by preparing and covering a cap 8 having an inner shape that matches the outer shape of the head 6. Becomes

The outer shape of the cap 8 is also polygonal, and the cap 8 is fitted in the opening of the surface plate 2 having a shape matching the polygonal shape.
It is desirable in order to prevent the support leg 5 from rotating due to a vibration caused by a person walking during use. In this case, the position of the corner of the polygon of the head 6 of the support leg 5 and the position of the corner of the polygonal opening provided on the upper surface plate 2 are displaced so that the cap 8 cannot be fitted. It may be possible to use a means such as attaching an alignment mark or the like to the position where is aligned. The height deviation in this case is at most 1 due to the number of polygonal corners of the support leg head 6.
Since the pitch is about / 6 to 1/8, there is no problem.

As the structure for adjusting the height of the leg 3, various structures can be considered in addition to the above-mentioned structure.
The structure shown in the figure is excellent because the height can be adjusted from the side, the molding is simple, the number of parts is small, the structure is simple, and the strength is excellent.

[0014]

According to the flooring material of the present invention, since the height of the legs can be adjusted, the height of the top surface of the flooring material can be easily adjusted even when the flooring material is spread over a swelling concrete floor surface or the like. It is very effective in practical use.
