Description

[Detailed description of the invention] <<Industrial application>> The present invention relates to floor finishing materials, in particular, carpet material is used as a floor surface material, and the material is defined into small pieces of regular shapes such as squares, and is densely placed on the target floor slab. Concerning carpet tiles that are used by laying them down.

《Prior Technology》 Recently, flat cable (thin cable) wiring has been developed so that wiring can be done directly on the floor slab for wiring when installing and moving OA equipment or computer terminal equipment, etc. It has come to be used as carpet wiring. This flat cable has a main body thickness of 1 to 2 mm and a thickness of 3 to 5 mm including the protective cover.
It has a thickness of about mm, and has become easier to install by wiring it directly onto the floor slab and laying floor finishing materials such as carpet tiles on top of it.

《Problem that the invention aims to solve》 However, even the thinnest cable has a thickness of about 3 to 5 mm including the protective cover, and since floor covering material is laid directly on top of this, the cable part inevitably becomes convex. The surface of the floor finishing material needed to be made flat, as blistering, partial abrasion, and peeling of the finishing material could impair its aesthetic appearance and cause people to trip over it while walking.

The present invention was developed in view of the above circumstances, and its purpose is to be easily applicable to simple electrical wiring that is changed according to the purpose of indoor use, and to ensure that the surface of the finishing material is always flat. We provide the best tile carpets.

<Means for Solving the Problems> In order to achieve the above object, the present invention is to stack a floor finishing material, a cushion material, and a base material integrally in order, define them to predetermined dimensions, and apply them to the floor. In tile carpets that are used to be densely laid on a plate, a tunnel-shaped wiring through-hole is formed in the cushion material in the lateral direction, and the through-hole has an inner wall on the inner wall surface of the upper half of the through-hole. It is characterized in that a protective frame is fitted in contact with the inner wall surface of the lower half and spaced apart from the inner wall surface of the lower half.

<<Operation>> The individual carpet tiles are arranged in succession so that the through holes in the individual carpet tiles communicate from the desired position to the target position, and the through holes are used like wiring ducts. Pressure and compression from above will not damage the wire body due to the distortion and elasticity of the protective frame inside the cushion material, the floor finishing material, and the base material.

Further, a protective frame adopted to protect the wiring is inscribed in the inner wall surface of the upper half of the through hole formed in the cushion material constituting the tile carpet, and is arranged so as to be spaced from the inner wall surface of the lower half. Therefore, when the tile carpet is stepped on, the protective frame is
In order to avoid resistance to this trampling force, the protective frame moves with the deformation of the through-hole inside the cushion material, and prevents a rough feel when buried in carpet, which has a characteristic of flexibility. By preventing this, the original elasticity of the tile carpet can be maintained well.

<<Example>> Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

Figures 1 and 3 show the planes of tile carpets 1, 2, and 3 according to the present invention, and these tile carpets 1, 2, and 3 are composed of a floor finishing material 4 made of woven fibers and a floor finishing material. A cushion material 6 is sandwiched between a base material 5 that maintains the planar shape of 4, and the cushion material 6 is laminated to a fixed length in a square having a side of 600 mm.

And these tile carpets 1, 2, 3
There are two types, one in which the wiring is guided in a different direction, and the other in which the wiring is not taken into consideration.The one shown in FIG. A semicircular protection frame 8 is fitted into the inner peripheral surface of the through hole 7 so as to be inscribed in the inner wall surface of the upper half of the through hole 7 and spaced apart from the inner wall surface of the lower half. Further, the tile carpet 2 shown in FIG. 2 has wiring through holes 7 that intersect diagonally. Furthermore, the tile carpet 3 in Fig. 3 has through-holes 7 for wiring.
This is a normal type without any .

These three types of carpet tiles 1, 2,
3 on the floor slab 9. The tile carpets 1, 2, and 3 of this embodiment having the above configuration are available in many types with through-holes 7 for wiring formed inside them, so the tiles can be individually selected according to the intended wiring route and wiring cable. It is possible to selectively arrange the tile carpets 1, 2, and 3. Therefore, carpet 1,
The desired wiring space can be obtained by only partially changing the arrangement of points 2 and 3. That is, the through-hole 7 can be formed as desired by appropriately selecting the tile carpet 1 and the tile carpet 2 and arranging them in succession so that the through-hole 7 communicates with the required shortest path from a certain position to the position where the target object is installed. Configures a communication hole for wiring. Signal lines and cables for office automation equipment, communication equipment, etc. are inserted through the through hole 7. The cross-sectional shape of the through-hole 7 may be square as shown in FIG. 4, depending on the cross-sectional shape of the signal line cable to be inserted, or it may be formed in parallel with large and small circular cross-sections as shown in FIG. good. Alternatively, it goes without saying that it may be formed into a horizontally long flat shape to match the flat cable.

As described above, the inner diameter and cross-sectional shape of the through-holes 7 are selected depending on the type and cross-sectional shape of the wiring, and these through-holes 7 are adjacently connected to each other to form and provide a wiring space suitable for the wiring route.

The protection frame 8 prevents the cable from being compressed directly and locally by the pressure exerted by objects placed on the tile carpets 1 and 2 or by people stepping on them. Furthermore, the protective frame 8 employed to protect the wiring is inscribed in the inner wall surface of the upper half of the through hole 7 formed inside the cushion material 6, and is spaced apart from the inner wall surface of the lower half. When the tile carpet 2 is stepped on, the protective frame 8 can be moved along with the deformation of the through hole 7 inside the cushion material 6 so that it does not act as a resistance to this trampling force, and the inherent elasticity of the tile carpet 2 is maintained. Can be maintained in good condition.

In addition, each thickness of tile carpet 1, 2, 3 is
The diameter or height of the through hole 7 at that time is about 15 to 20 mm. Further, the protective frame 8 may be made of flame-retardant hard plastic.

<<Effects>> As described in detail above, according to the tile carpet of the present invention, the individual carpet tiles are arranged continuously so that the through holes of the individual carpet tiles communicate from the desired position to the target position, and the through holes are connected to each other. Can be used like a wiring duct. In response to pressure or compression from above, damage to the wire body can be prevented by the distortion and elasticity of the protective frame inside the cushion material, the floor finishing material, and the base material.

In addition, the protective frame adopted to protect the wiring is inscribed in the inner wall surface of the upper half of the through hole formed inside the cushion material, and is spaced apart from the inner wall surface of the lower half, so that the tile carpet When a carpet is stepped on, the protective frame moves along with the deformation of the through-hole inside the cushion material so as not to resist this trampling force. It is possible to prevent the tile carpet from having a rough feel when buried, and to maintain the original elasticity of the tile carpet well.

In addition, the surface can be finished flat, and the floor covering material does not lose its aesthetic appearance due to partial wear or peeling, and it also has the advantage that it does not cause tripping while walking.

Furthermore, since a protective frame is fitted into the through-hole so as to be inscribed in the inner wall surface of the upper half of the through-hole, the cross-sectional shape of the through-hole is easily maintained due to the strength of the base material, and even during wire entry work. The wire entry tip is locked on the inner wall surface of the through hole, which does not obstruct the wire entry work and has the effect of protecting the wiring cable from partial compression against the tile carpet.
