Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel in which a power cord can be freely wired when installing office automation equipment such as word processors, computers and communication equipment in offices, schools and the like.

[0002]

2. Description of the Related Art The development and popularization of OA equipment such as word processors, computers, and communication equipment are remarkable, and with the development and popularization of this OA equipment, a large number of power cords and connecting cables are to be installed indoors. Crawling these power cords on the floor not only spoils the appearance, but also causes a trip, causing injury or a break in the OA equipment. Therefore, there has been proposed a floor panel capable of storing a large number of these wirings under the floor. For example, as a known example 1, "O" described in Japanese Patent Laid-Open No. 5-10023 is disclosed.
There is a floor panel of "Construction method of floor structure for A". As shown in FIG. 12, this floor panel has a plurality of convex portions 2 that are cut at arbitrary positions at predetermined intervals in parallel on either the front surface or the lower surface of the floor base plate 1. It will be. Then, these floor panels are placed on the floor surface, the wiring 4 is housed in the groove 3 between the adjacent convex portions 2, the convex portion 2 is partially cut off at a desired position, and the cut portion is passed through the cut portion. The wiring is guided to the adjacent groove to perform the wiring in the vertical and horizontal directions, and the floor finishing material is laid on the floor panel with or without an intermediate member.

Also, as a known example 2, FIGS.
There is a floor panel shown in. 13 is a top perspective view, and FIG. 14 is a bottom perspective view. This floor panel is provided with leg portions 7 at the four corners of the bottom surface of the floor portion 6 including the crosspieces 5 and 5a, the middle portion and the center portion thereof, and is reinforced by the reinforcing rib group 8 provided on the lower surface. That is, the reinforcing rib group 8 includes reinforcing ribs 9 and reinforcing ribs 10 that connect the leg portions 7, and vertical ribs 11 and horizontal ribs 1 that connect the reinforcing ribs 8 at an intermediate position of the reinforcing ribs 9.
2, diagonal ribs 13, and three reinforcing ribs 9 are provided in parallel. The leg portion 7 of the reinforcing rib group 8 is
The lower surfaces of the reinforcing ribs 9 and 10 that connect the
Is inclined in the vicinity of, and therefore, a concave shape is formed between the leg portions 7. To use the floor panel of the above configuration,
The legs 7 are placed on the floor and laid out side by side, and the floor and the reinforcing rib group 8
The power cord is wired between the leg portions 7 in the space between and.

[0004]

However, the floor panel of the above-mentioned known example has the following problems. That is, in the known example 1, the wiring between the adjacent grooves 3 has the convex portion 2
Although it can be performed by cutting off at any position, it takes time and time to cut, and after the position of the wiring is determined in advance, the convex portion 2 is cut off when the floor panel is laid according to it. Other than wiring, it is impossible to wire after laying the floor panel. Moreover, since the floor surface is not necessarily a horizontal smooth surface, the entire convex portion 2 is not placed on the floor surface. Therefore, there is a risk that a part of the convex portion 2 will be in a floating state and rattling will occur, and a walking sound will be produced.

Unlike the known example 1, the known example 2 has a gap between the leg portions 7 so that wiring can be made in the vertical and horizontal directions even after the floor panel is laid, and the gap is formed by the crosspiece and rib structure. It is possible to wire while looking at the direction of the power cord. However, since the leg portions 7 are also provided at the four corners and the middle portion thereof, the distance between the leg portions is narrowed, which makes it difficult to pass the power cord during wiring. Also, 9
Since it is composed of three legs, not all the legs are placed on the floor as in the case of the known example 1, and therefore there is a problem that the walking sound is likely to be produced by the floating legs.

Further, in both the known examples 1 and 2, since the side surface of the floor panel is smooth, there is a problem that the floor panel is not positioned when laid on the floor surface and is difficult to construct. The present invention has been made in view of the current situation, and provides an OA floor panel that has sufficient strength, is easy to be horizontal to the floor surface, and is easy to construct and wire.

[0007]

The present invention has the following configuration to achieve the above object. That is, in the floor panel according to claim 1 of the present invention, the projection is formed on one side surface of the four corners of the flat rectangular upper plate and the recess is formed on the other side surface, and the lower surface of the four corners is formed. A horizontal projection,
A load leg having a height slightly lower than that of the leveling protrusion is provided, and an elastic cap is fitted to a tip end of the leveling protrusion, and a lower surface of the upper plate is further attached. It is characterized in that a rib having a height lower than that of the load leg portion is provided. A floor panel according to a second aspect of the present invention is characterized in that the leveling protrusion and the load leg are provided on a diagonal line connecting four corners of the upper plate. A floor panel according to a third aspect of the invention is characterized in that the leveling protrusion is provided outside the loading leg. A floor panel according to a fourth aspect of the invention is characterized in that the leveling protrusion is provided inside the loading leg.
