Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to carpet tiles that are laid side by side on the floor.

Conventional wide and long car vents are difficult to transport, require a lot of skill to install, and have to be replaced entirely if localized damage occurs. The adoption of carpet tiles that can solve this problem is increasing.

By the way, there are several conditions that must be met in order to achieve a beautiful finish with carpet tiles that are laid one after another on the floor.

The first condition is that no expansion or contraction occurs due to temperature changes.

For this reason, the backing layer provided on the back side of the pile layer has a hardness of 90~
100, or insert cloth, woven cloth, etc. into the middle part to prevent expansion and contraction to form a multilayer structure.

However, a hard backing layer tends to cause slippage during installation, and a multilayer structure complicates the manufacturing process and increases product cost.Moreover, the hardness of the backing layer makes it an important requirement for car vents. A certain elasticity is lost, and the product value decreases.

The second condition is that it does not move in all directions relative to the floor.

For this reason, all or part of the back side of the tile carpet is fixed to the floor surface with adhesive, but since the adhesive is bonded to the floor surface during construction, there is a resistance to movement of the tile carpet, and the position of each tile is fixed. #Adjustment work is difficult, and the adhesive transfers to the floor/surface, causing damage to the floorboards.

The third condition is to ensure that there are no gaps between the adjacent carpet tiles.

However, since the backing layer is hard, it is difficult to compress the periphery during installation, and the pile density at the joint portion becomes coarse during installation, reducing the finished value.

This invention was developed in view of the above points, and it can be laid without using adhesive, and there is no movement during laying, and there is no gap between adjacent carpets at the joints. The purpose is to provide carpet tiles that are not available in the market.

It is formed into a convex surface and increases the contact area with the floor surface due to load, thereby preventing movement without using adhesive.

Hereinafter, the present invention will be explained based on embodiments shown in the accompanying drawings.

As shown in FIG. 1, the tile carpet 1 is formed by providing a backing layer 5 on the back side of a pile layer 4 having loops 3 on a base fabric 2.
The backing layer 5 has elasticity, and its ground contacting bottom surface has an uneven surface 6, so that it exhibits an anti-slip effect between it and the floor surface.

Examples of the material for forming the backing layer 5 include various synthetic resins and rubbers, and the hardness of the backing layer 5 is 50 to 50.
It's around 60.

The uneven surface of the backing layer 5 may be formed using a mold using the material for forming the backing layer 5 itself, but as shown in the figure, an uneven surface that is harder than the backing layer 5 mixed in the backing layer 5 may be used. 7
It may be formed by protruding a part of the surface, and various anti-slip effects can be obtained depending on the number, pattern, and height of the projections and recesses.

Incidentally, various formulation examples are shown when the backing layer 5 is made of vinyl chloride resin.

200-30% plasticizer for 200g of vinyl chloride resin
0g of calcium carbonate as a filler.
0! i. If you mix 5I of stabilizer and 10g of wood powder or rubber sponge powder of about 0.5 to 1 yen as the stabilizer, the hardness will be around 50 to 60 as shown in Fig. 3 with the extender 7 protruding from the back side. The backing layer 5 can be manufactured.

The tile carpet of the present invention has the above-mentioned structure, and is sequentially laid on the floor as shown in FIG. At this time, as shown by the arrows in the figure, the carpet tiles 1 are compressed in all directions 7L17' and are either closely arranged or arranged in close contact with each other.

When compressed from all sides, the backing layer 5 of the tile carpet 1 crushes the joining edge with the adjacent carpet due to its rebound resilience, making the periphery of the pile layer 4 dense and making the joining part inconspicuous.

As described above, each tile carpet 1 is simply installed on the floor surface and is not fixed with adhesive, so that the protruding portions of the uneven surface 6 are simply in contact with the floor surface.

When a person walks in this state and a local load is applied to the tile carpet 1, the part that receives the load is compressed, and the convex part of the compressed part's uneven surface 6 sinks into the inside of the backing layer 5. By doing so, the entire back side comes into contact with the floor surface, and therefore, even with a light load such as a child's weight, the tile carpet 1 has an anti-slip effect on the floor surface, and it is possible to lay it on a single layer. Even if the carpet tile 1 is moved only by itself, the positional shift will not occur in the carpet tile 1.

In addition, the periphery of the tile carpet 1 will be pulled in toward the part that received the load, but since the back side is not bonded to the floor surface, when the load is released, the periphery will be pulled back to the adjacent tile. This means that there will be no gaps at the joint.

As described above, according to the present invention, since the configuration is as described above, there are the following effects.

(1) Provide an elastic backing layer on the back side of the pile layer,
Since the ground surface of this backing layer has an uneven surface, when a pedestrian's load is applied, it is possible to obtain a pressure contact between the ground surface and the floor surface that has a sufficient anti-slip effect, without using adhesives. , can be laid on the floor.

(2) Since the backing layer has elasticity, it can be laid by compressing the joint part with the adjacent tile carpet, increasing the density at the joint part of the pile layer and preventing the generation of gaps.

(3) There are no gaps in the joints when laying, and the density of the pile layer can be increased, resulting in a product with a beautiful finish and high commercial value.

(4) Since there is no need to glue it to the floor surface, the adhesive will not damage the floor surface.

(5) Since there is no need to glue the floor surface, it can be laid while being moved freely, and construction work can be carried out efficiently.

(6) Since it is only necessary to provide a backing layer on the back side of the pile layer, the structure is simple and the manufacturing cost is low.
