Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a tile carpet laid on the floor of a building, particularly on the top of an undercarpet wiring system.

(Prior Art) Conventionally, tile carpets have been known in which pile layers are provided on the front and back surfaces, and a layer made of a hard material such as polyvinyl chloride is provided in the middle between the pile layers. There is.

(Problem to be solved by the invention) In the conventional tile carpet, since the front and back sides each form a pile layer, not only the front side but also the back side can be used by inverting.
This improved not only the durability but also the interior decoration quality, but when an undercarpet wiring system etc. was installed under the tile carpet,
Since the tile carpet does not have elasticity in the thickness direction, the part of the tile carpet corresponding to the installation location bulges, making it difficult to walk on, and there is a risk of tripping when walking on the step between the floor surface and the undercarpet wiring system. It was hot too.

(Purpose of the invention) In view of the above-mentioned conventional problems, the present invention not only improves durability and interior decoration, but also provides a tile car that is easy to walk on and has a good appearance by absorbing differences in level even when there is something laying on the bottom surface. The goal is to provide pets.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides pile layers on the front and back surfaces, and the intermediate portion sandwiched between the pile layers has flexibility and an independent structure. A stretchable layer formed of a member containing cells or open cells and having stretchability in the thickness direction is provided, a support layer made of a hard member is provided in contact with one surface of the stretchability layer in the thickness direction, and the support The layer is characterized in that it has the ability to restrict expansion and contraction in the horizontal plane direction of the stretchable layer.

(Function) According to the present invention, since the pile layer is provided on the front and back sides, not only the front side but also the back side can be reversed and used, and when a force is applied in the thickness direction, the pile layer is provided on the elastic layer. The carpet section to which the force is applied contracts because the closed or open cells are collapsed and the volume is reduced. On the other hand, when the force applied in the thickness direction is removed, the volume of the bubbles that had been reduced returns to its original volume, so that the partially shrunk carpet returns to its original thickness. In addition, the support layer made of hard polyvinyl chloride, etc., in contact with the elastic layer restricts the expansion and contraction of the elastic layer in the horizontal direction, so as the tile carpet is used repeatedly, it tends to It never shifts.

(Embodiment) FIGS. 1 and 3 show an embodiment of the present invention.
That is, 10 is a tile carpet, 11 is a front pile layer, 12 is a back pile layer, 13 is a front side primary base fabric, and 14 is a back side primary base fabric. 15 is a member having flexibility and containing closed cells or open cells;
For example, an elastic layer made of sponge is provided between the primary base fabrics 13 and 14. 16 is the elastic layer 15
The support layer is provided in contact with one surface in the thickness direction of the support layer, and is made of a hard material such as polyvinyl chloride. A convex inclined portion 20 is provided on both side surfaces of the tile carpet 10 that sandwich one corner, and a convex inclined portion 20 is provided on both side surfaces that sandwich a diagonal corner of the corner. are provided with concave inclined portions 21 of the same size and at the same position.

30 is a flat cable constituting the undercarpet wiring system, and 40 is a floor surface.

According to this embodiment, the tile carpet 10
When laying a carpet on a floor surface 40 in a room, a flush surface is formed by overlapping the convex slope portions 20 and concave slope portions 21 of the adjacent carpet tiles 10.

Further, according to this embodiment, the tile carpet 1
0 is provided with a front pile layer 11 and a back pile layer 12, so when the front pile layer 11 becomes dirty or damaged, it can be simply reversed to the back pile layer 12, which not only improves durability but also improves durability. By changing the colors of the front pile layer 11 and the back pile layer 12, it is possible to change the interior decoration. When the flat cable 30 is laid, the improvement in cushioning properties and elasticity due to the double pile layer of the front pile layer 11 and the back pile layer 12 and the expansion and contraction of the elastic layer 15 formed of sponge combine to improve the flat cable 30. The level difference with the floor surface 40 can be sufficiently absorbed. Further, a support layer 16 made of hard polyvinyl chloride or the like is in contact with the elastic layer 15.
This restricts the expansion and contraction of the elastic layer 15 in the horizontal direction, so that the tile carpet 10 will not shift in the horizontal direction as it is used repeatedly. Furthermore, since the stretchable layer 15 enhances the shock-absorbing effect against shocks and vibrations, the propagation of shocks and vibrations to the downstairs, adjacent areas, etc. can be softened, and damage to the flat cable 30 can be prevented.

(Effects of the invention) As explained above, this invention has a pile layer on the front and back sides, so not only the front side but also the back side can be used by reversing, which not only improves durability but also improves the Not only can you change the interior decoration by changing the color of the pile layer and back pile layer, but it also has flexibility.
In addition, since the elastic layer is made of a member containing closed cells or open cells and has elasticity in the thickness direction, the double pile layer on the front and back surfaces improves cushioning properties and elasticity. Together with this, it is possible to provide a flat carpet surface that sufficiently absorbs the difference in level between the floor surface and the laying material provided on the lower surface, and has the effect that it is easy to walk on and there is no risk of tripping. Furthermore, since the elastic layer further enhances the shock-absorbing effect against shocks and vibrations, it is possible to reduce the propagation of shocks and vibrations to the downstairs, adjacent rooms, etc., and also prevent damage to the objects laid on the lower surface. In addition, the support layer made of a hard material in contact with the elastic layer restricts the expansion and contraction of the elastic layer in the horizontal direction, so that the tile carpet will not shift in the horizontal direction as it is repeatedly used. It has the effect that there is no
