The undercarpet cable, however, has a drawback that it is difficult to dispose and install, and it requires skillful technique to install it without causing swelling especially at the bent portion. Further, although the undercarpet cable is flat, it has a certain thickness, so that there is a problem that an uncomfortable feeling occurs when walking on the carpet. Then, since the carpet portion on the cable is formed with a slight raised portion, there is also a problem that dirt adheres only to that portion. Further, in the electric circuit using the undercarpet cable, the cable position after laying the carpet cannot be accurately grasped, and for example, when the anchor is struck on the slab for the purpose of partition construction, the electric circuit is accidentally cut. There was fear. The present invention has been made in view of the above situation, and can be easily installed without requiring skill, and does not cause discomfort during walking,
Moreover, it is an object of the present invention to provide a tile carpet with a built-in electric circuit that enables the position of the electric circuit to be easily grasped, and to improve workability, walking feeling, and safety.

[0004]

In order to achieve the above object, a tile carpet having a built-in electric circuit according to the present invention has a structure in which a pile is planted on the upper surface of a quadrangular plate-like base material and an insulating conductor is formed on the base material. Which is provided inside at a predetermined position, at least a pair of parallel sides of the base material are formed with different stepped portions in which the corners on the upside-down side are cut out, and which are laid adjacent to each other. It is characterized in that it is possible to connect the base materials to each other in a staggered joint manner between the step portions, and to expose the electric path at the step portion so that the electric path is connected when the step portions are connected. is there.

[0005]

The electric circuit is embedded in the base material by integral molding, the cable does not exist between the slab and the carpet unlike the conventional under carpet cable, and the electric circuit portion does not rise after the carpet is laid. In addition, by being laid on the slab in sequence, the electric path is connected through the connection part,
No special skill required for laying. Furthermore,
Electric lines are provided at predetermined intervals from each side of the tile with built-in electric line, and by measuring the distance from the two sides that are orthogonal to each other, it is possible to identify the portion where wiring is not provided.

In the tile carpet 1 with a built-in electric circuit of this embodiment, piles 5 to be fluff are planted on the upper surface of a plate-shaped base material 3. The base material 3 is made of an elastic material such as rubber or soft vinyl, and each of the plurality of base materials 3 is formed into a square having the same size.

The base material 3 has a built-in electric path 7 including, for example, a power supply wiring 7a, a telephone wiring 7b, an OA wiring 7c, and each wiring 7a, 7b, 7c is a plurality of flat cable-shaped insulated conductors. Composed. The electric path 7 is integrally formed with the base material 3 by, for example, insert molding. Steps 9 are formed on both sides 3a and 3b of the base material 3 in the front-rear direction.
a and 9b are formed, and the corners on the opposite sides of the step 9a and the step 9b are cut away. Therefore, the base materials 3 adjacent to each other in the front-rear direction are connected by the step portions 9a and 9b in a phased joint shape (see FIG. 3). The steps 9a and 9b are
In addition to the front and rear ends, the sides 3c at the left and right ends of the base material 3,
It may be formed in 3d. In this case, the adjacent base materials 3 are connected in the front-back direction and the left-right direction in the form of a continuous joint. Further, the steps 9a and 9b may be formed only on two adjacent sides, for example, 3a and 3d.

The electric circuit 7 formed integrally with the base material 3 has a step 9
The connection portion 11 is exposed at a and 9b. Connection part 11
In the electric circuit 7 at the same time, the exposed surfaces are in close contact with each other and electrically connected at the same time when the tile carpets 1 with a built-in electric circuit are laid. The electric path 7 in the connecting portion 11 is
In addition to the structure in which exposed surfaces are simply and closely connected in the vertical direction,
It may have a terminal structure. As the terminal structure, for example, a pin-shaped male terminal (not shown) is vertically provided on the upper step 9a, while a cylindrical female terminal (not shown) is vertically provided on the lower step 9b. It is conceivable that the male terminal and the female terminal are fitted in the vertical direction at the same time when the step portions are connected. In this case, if the terminal fitting portion has an airtight structure, the waterproof and dustproof properties can be improved.

The tile carpet 1 with a built-in electric circuit is provided with a plurality of variations with different wiring types and different electric circuit patterns so as to be compatible with various layouts. For example, as the wiring type variations, only the power supply wiring 7a, the telephone wiring 7b, the OA wiring 7c,
Only the power supply wiring 7a and the telephone wiring 7b are prepared, that is, the wiring configured by a single type of electric path 7 or the wiring configured by a plurality of types of electric paths 7.

Further, as a variation of the electric circuit pattern, as shown in FIG.

[0013]

As described in detail above, according to the tile carpet with a built-in electric path according to the present invention, since the electric path is internally provided in the base material, as in the conventional undercarpet cable, the space between the slab and the carpet is reduced. Since the cable does not exist in the room, there is no discomfort when walking, and the electric circuit part does not rise after laying the carpet. Further, since the conductor is exposed at the step so that the conductor is connected at the time of connection, no special skill for laying is required, and the construction can be easily performed. Further, since the electric path is provided at a predetermined position, it is possible to easily identify the portion where wiring is not provided by measuring the distance from the two sides that are orthogonal to each other. As a result, walking feeling, workability, and safety can be improved.
