Description

[Detailed Description of the Invention] This invention relates to a carpet tile that can be laid like a tile, particularly a carpet tile that can be laid down accurately and easily.

The conventional and common method for laying carpet on a floor is to use a wide, long piece of carpet, cut it to the size of the room, and then glue it to the floor.

Carpets installed indoors are prone to severe damage in areas such as passageways, and with single-piece carpets, there is an economic disadvantage in that the entire carpet must be replaced if it is partially damaged.

In addition, long carpets are inconvenient to transport and install, and special techniques and tools are required to install them, such as cutting and gluing, which has hindered the spread of carpet into households. There is.

In recent years, in order to solve the problems of such long carpets and to make it possible to lay carpets without the need for special techniques or tools, in recent years carpets have been cut to a certain size in advance, and carpets have been cut to exactly the right size. Carpet tiles have been proposed that can be installed simply by arranging them like tiles.

The carpet tiles mentioned above are pre-cut to a certain size, making them easy to transport and install, and even after installation, they can be partially replaced, making them economical and available in different colors. This allows for free combinations of handles and handles, and does not require any special tools for installation.

This type of carpet tile is made of a long carpet with hairs planted on the surface of the laminate, for example, 50 mm.
The conventional general structure is that it is formed by cutting into square corners, and adhesive is applied to the entire back side to fix it to the floor.

Carpet tiles are cut with high precision to ensure that the abutting edges are straight when laid, and there are no bends or misalignments, so there are no errors in size.

Therefore, when laying carpet tiles one after another, it is necessary to attach them to the floor surface so that there is no gap between the circumferential edge and the circumferential edge of the previously laid carpet tile. It often occurs that the edges are in close contact with each installed carpet tile.

Carpet tiles have loops and bristles planted on the surface of the laminate, so the loops and bristles protrude from the peripheral edge of the laminate. Press the carpet tiles together so that the parts that protrude from the side edges are compressed together,
It is necessary to attach the laminate to the floor surface with the circumferential edges in contact with each other, and if the two circumferential edges are to be joined at the same time, the carpet must be pushed in in two directions at the same time.

However, with carpet tiles in which adhesive is applied to the entire bottom surface, or conventional carpet tiles in which adhesive is applied only to the outer periphery of the bottom surface as in Utility Model Publication No. 55-49026, it is difficult to place tiles on the floor. Once set on a surface, the adhesive adheres to the floor surface and loses its mobility, making it extremely difficult to accurately press the carpet tile against the previously laid carpet tile. It is difficult to bring the side edges close together, which creates additional problems such as gaps between the carpet tiles, which can cause misalignment and bending of the carpet tiles.

This idea was made to solve the above problems, and the adhesive on the bottom of the carpet tile is removed at the surrounding area, so that the adhesive prevents the carpet tile from moving during installation. The object is to provide carpet tiles that can be laid freely and unobstructed and one after the other without any gaps.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, a square-cut carpet tile 1 is formed of a laminate 2 and bristles 3 provided on its surface.

Although not shown, the laminate 2 is formed by appropriately selecting the combination and thickness of felt, foam, cushion, coltar, etc. on the base fabric, and the hair 3 on the surface is only made of short hair. Alternatively, it may be formed by looping or raising.

The bottom surface of the laminate 2 in the carpet tile 1 is formed into an arcuate surface 5 recessed toward the center as shown in FIGS. 2 and 5.

The arcuate surface 5 can be formed by making the entire laminate 2 arc-shaped, as shown in FIG. 5, or by forming only the bottom surface of the laminate 2 into a concave surface, for example by heating It can be easily obtained by processing.

An adhesive 6 is provided on the bottom surface of the carpet tile 1 except for the periphery of the bottom surface of the tile, and is protected by release paper 7.

In the case of Figures 1 to 4, the adhesive 6 is distributed at four locations on the bottom surface, and Figure 5 shows an example in which it is provided only in the center of the bottom surface, but the location and size of the adhesive Various patterns can be selected, provided that a suitable amount of the bottom surface is left intact around the bottom surface.

When the bottom surface of the carpet tile 1 is formed into an arcuate surface 5 and the adhesive 6 is provided on the arcuate surface 5 at a position closer to the inside than the outer periphery of the carpet tile 1, the carpet tile 1 can be grounded to the floor surface. Even if the carpet tile 1 is positioned, the adhesive 6 floats up from the floor surface and the planar movability of the tile 1 is maintained. When pressed, the adhesive 6 will act on the floor surface.

The carpet tile of this invention has the above-mentioned structure, and the method of laying it will be explained next.

Adhesive 6 with carpet tile 1 on the bottom
With the release paper 7 removed, they may be placed closely on the floor and fixed with adhesive 6.

The case where the circumferential edges are pressed against each other when the carpet tile 1 is laid will be explained with reference to FIG. 3.

To continue laying and attach the carpet tile 1a shown by the dashed line in Fig. 3, place it facing the floor with the release paper 7 peeled off, and attach the two adjacent circumferential edges first. Press against the carpet tile.

In this pressing operation, since no adhesive is provided around the carpet tile 1 and the bottom surface is an arcuate surface 5, the adhesive 6 rises from the bottom surface, allowing the carpet tile to move freely. Since the adhesive 6 does not impede mobility at all, the circumferential edges of the laminate 2 can be brought into pressure contact with each other, and as shown in FIG. 4, there is no gap at the abutted portion.

If the carpet tile 1 is pressed from above with the peripheral edges pressed together in this way, the adhesive 6
It is fixed to the floor surface, and by repeating this process sequentially, it can be installed throughout the room.

In addition, as shown in FIGS. 2 and 5, since the laminate 2 is curved, when it is attached to the floor surface with the adhesive 6, the periphery of the carpet tile 1 comes into pressure contact with the floor surface, and the tile periphery The peeling prevention effect is improved.

Further, the carpet tile is not limited to a square shape as shown in the illustrated embodiment, but a rectangular shape or a shape with each corner cut in an inclined shape can be adopted.

As described above, according to this invention, the bottom surface of the carpet tile is formed into an arcuate surface that is concave toward the center, and the adhesive is provided at positions other than the periphery of this bottom surface. When pasting to a surface, the adhesive can be prevented from coming into contact with the floor surface, and the movability of the carpet tile during pasting allows the surrounding edges to be pressed against each other, eliminating the generation of gaps. Laying will be obtained.

In addition, since the circumferential edges of the carpet tiles can be pressed against each other on both sides and laid without any gaps, carpet tiles can be laid accurately without the need for special techniques. Become,
It will be possible to greatly expand the spread of carpet tiles.

Furthermore, since the carpet tile has an adhesive near the center of the bottom surface, it can be fixed by pressing it onto the floor surface, and since the bottom surface is an arc-shaped surface, the surrounding area against the floor surface can be fixed. Adhesion is further improved, so there is no peeling, etc.
You can take advantage of the advantages of carpet tiles.
