Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an OA mat suitable as a mat to be laid on the floor of an office where wiring to OA equipment and the like is performed on the floor.

[0002]

2. Description of the Related Art As offices have become more intelligent,
Wiring to OA equipment and the like cannot be accommodated in conventional wiring capacities, and have been running around the office in all directions.

[0003] For this reason, it is becoming common to install an OA floor having a larger capacity than a conventional concrete driving pipe or duct. The OA floor has a double floor structure in which a free access floor used for a floor having a large wiring capacity such as a computer is lowered, and its height is generally about 60 to 100 mm. .
That is, in the OA floor, the structural floor (floor body)
Separately, a floor panel is laid above the structural floor, and electric infrastructure such as power lines, signal lines, and telephone lines is wired between the structural floor and the floor panel.

[0004]

However, in an existing structure having a low ceiling height, providing an OA floor on the structural floor is not suitable because the floor becomes too high. Therefore, in existing structures with low ceiling height, wiring is usually exposed on the floor.However, when the power cord etc. is laid on the floor, not only does it not only impair the aesthetic appearance but also It may cause disconnection or failure of OA equipment.

[0005] Further, since the OA floor is susceptible to the sound of walking and requires adjustment of the floor level, the OA floor is suitable for laying work such as appropriate selection of floor panel materials and securing of level accuracy. It takes time.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and a floor wiring is easily hidden even in an existing structure having a low ceiling height without newly providing a double floor. It is an object to provide an OA mat that can be put into a state.

[0007]

Means for Solving the Problems In order to solve the above problems, the invention according to claim 1 of the present invention is provided with a flat base material contacting a floor main body and provided on the base material. A flat cushion material, a flat lower cover provided on the cushion material and having a predetermined rigidity, a column projecting upward from the lower cover, and supported by the column. An OA comprising a flat upper cover having a predetermined rigidity and disposed opposite to the lower cover with a predetermined gap, and a carpet provided on the upper cover.
To provide a mat for use.

In the present invention, wiring can be accommodated in the space between the upper and lower covers simply by laying the OA mat according to the present invention on the floor body (structured floor). At this time,
By providing the upper and lower covers with a predetermined rigidity, it is possible to prevent the space for wiring from being closed by the load applied to the upper and lower covers.

Further, since the walking sound is suppressed by the carpet, a quiet offos is secured. In addition, the presence of the base material allows integration with the floor main body, and the cushion material absorbs irregularities on the floor main body surface. Here, as the base material, a flexible member such as a rubber material is preferable in consideration of the familiarity with the floor main body and adhesion.

Next, a second aspect of the present invention is the first aspect.
In the above configuration, a flat second cushion member is interposed between the upper cover and the carpet.

The presence of the second cushioning material prevents the impact from the carpet from being directly applied to the cover and the wiring below the cover. Next, according to a third aspect of the present invention, in addition to the configuration described in the first or second aspect, a through-hole penetrating upward from the upper cover and a lid member fitted into the through-hole are provided. It is characterized by the following.

By having the through holes, it is possible to draw out the wiring arranged between the upper and lower covers above the floor. Further, when it is not necessary to draw out the wiring upward, the dust is prevented from falling into the wiring space by being closed by the lid member.

Here, the lid member preferably has elasticity, and if it has elasticity, it can follow the deflection of the carpet and the cushion material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1 which is a perspective view and FIG. 2 which is an exploded view, the mat for OA of the present embodiment has a base material 1, a second cushion material 2, a lower cover 3, an upper cover 4, a cushion The material 5 and the carpet 6 are laminated. Each of the members 1 to 6 constituting the OA mat is formed into a square plate having the same dimensions.

The base material 1 is made of rubber, is hardly displaced when placed on a structural floor, and adapts to some irregularities of the structural floor by bending. The upper and lower cushion members 2 and 5 are made of a foam material or the like and are easily bent. The cushion material 2 may be omitted by making the rubber of the base material 1 thicker so that the base material 1 also functions as a cushion material.

The lower cover 3 and the upper cover 4 are made of, for example, a hard plastic, and are lightweight and have a predetermined rigidity. Since a plurality of pillars 7 are interposed between the lower cover 3 and the upper cover 4, a gap is provided between the lower cover 3 and the upper cover 4 such that a power cord 8 or the like can be wired. Is formed. The mat is easier to manufacture if the support 7 is formed integrally with the lower cover 3.

The OA mat having the above-described structure can be easily laid by merely laying it on the target structural floor, and a power cord and a connection cable are provided in the space between the lower cover 3 and the upper cover 4. Passing through such as 8 results in a state where the wiring is stored in the mat, that is, a state where the exposed wiring is avoided.

As described above, in the present embodiment, only a low-quality OA mat is laid on the structural floor with the feeling of laying a tile carpet or the like. Even if it is used for an existing structure having a low ceiling height, it is possible to prevent the ceiling height from becoming too low.

Moreover, the exposed wiring can be avoided and a state equivalent to the state where the wiring is stored under the floor can be obtained without newly forming a double floor structure. Further, even if there is some unevenness on the upper surface of the structural floor, the unevenness of the structural floor is absorbed by the conformity due to the flexibility of the base material 1 and the flexure of the cushion 2, so that the upper surface of the structural floor has some unevenness. Even if there is unevenness, the laid mat for OA is prevented from rattling.

Further, since the walking sound can be eliminated by the presence of the carpet 6, a quiet office can be provided. At this time, the impact from above due to walking or the like is reduced by the presence of the second cushion material 2, and the upper cover 4 and the wiring 8 located thereunder are protected.

However, the upper cover 4 and the lower cover 3
The rigidity of the mat may be increased to protect the wiring 8 reliably, but the rigidity of the mat is increased and the mat is hardly bent. Further, as shown in FIG. 3, a through hole 10 penetrating upward from the upper cover 4 may be provided so that the cord wired between the upper and lower covers 3 and 4 can be pulled out onto the floor. Here, reference numeral 9 indicates a structural floor.

In this case, a cover member 11 for closing the through hole 10 when the connection cord 8 or the like 8 is not pulled out is prepared, and the cover member 11 is fitted into the through hole 10 in a normal state. deep. The lid 11 is also preferably made of rubber so that it can follow the deflection of the cushion material 5.

The arrangement of the pillars 7 interposed between the upper cover 4 and the lower cover 3 is not limited to the four corners and the center as described above. It is only necessary that the spaces between them are arranged at intervals such that the power cords 8 and the like can be arranged so as not to be crushed by the assumed vertical load.

Alternatively, as shown in FIG. 4, the column 7 is formed so as to form a passage divided into a plurality of sections along a predetermined direction.
May be arranged so that wires such as power lines and signal lines can be separated and wired for each type of cable. In addition, by providing a space in the extending direction of the support portion 7 (portion A in FIG. 4), a predetermined bending of the mat is ensured.

In the above embodiment, the OA mat is described as having a square shape.
Any shape may be used as long as it can be laid continuously.

[0026]

As described above, the OA of the present invention is
If you use the mat, even in a room with a low ceiling height,
There is an effect that the wiring of the electric infrastructure can be easily hidden without carpeting, that is, the floor is not so high, and a quiet office can be provided.

Moreover, even if there is some irregularity in the floor body to be laid, the laying can be performed without rattling. At this time, when the invention described in claim 2 is adopted, there is an effect that the wiring passed through the mat can be further protected.

Further, when the invention described in claim 3 is adopted, even if the OA mat is laid on the entire surface of the structural floor, the wiring can be easily drawn out onto the floor.
