Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tile carpet in which a plurality of carpet pieces are laid adjacent to each other and are continuously laid in a vertical and horizontal manner depending on the width of the floor surface.

[Conventional technology]

Traditionally, a carpet was a single rug that was spread across a room.

In recent years, in place of this single carpet,
As shown in FIG. A, a so-called tile carpet has been developed in which a plurality of tile-shaped carpet pieces 9 are laid adjacent to each other on various floor surfaces or flat surfaces such as tatami mats. The carpet pieces 9 are generally square in shape, each having the same dimensions, as shown. FIG. 8B shows a cross section of the carpet piece 9, which consists of a flexible base material layer 2 made of rubber or synthetic resin such as polyethylene, and a fiber tissue layer 3.

The most important feature of carpet tiles is that they can be laid on floors of different sizes and shapes, making them more flexible than single-ply carpets. In addition, the price is reasonable, and since it is possible to remove all or part of the carpet tiles that have been laid, it is easy to clean after installation and repair worn or damaged carpets, making it easy to maintain the carpet. It is advantageous in

Regarding carpet tiles, a so-called double-sided carpet has been developed that can be turned over and used as the front surface when the front surface becomes soiled (Utility Model Application Publication No. 38891/1983). FIG. 8C shows a cross section of a carpet piece of double-sided carpet, and as shown, fiber tissue layers 3 are provided on both sides of the base layer 2. Since double-sided carpets can be used on both sides, they have the advantage of having a long carpet life and reducing the frequency of cleaning, thereby saving money and labor.

[Problem that the invention attempts to solve]

However, the conventional tile carpet shown in FIGS. 8A to 8C has the following problems.

That is, the carpet is partially or intermittently pressed by heavy objects such as furniture and pedestrians that are unevenly distributed on it, but this pressure causes the rubber, synthetic resin, etc. Since the base material layer 2 made of the above-mentioned material is spread out to a greater extent, a portion of the carpet piece 9 swells up, and peeling and floating easily occur at the joint ends of the carpet piece 9. especially,
At a point 10 where the joining lines of adjacent carpet pieces 9 are concentrated, pressure from four directions is concentrated as shown by arrow a, so the occurrence of such peeling and floating becomes noticeable, and the vacuum cleaner gets caught. pedestrians trip. Furthermore, this problem becomes more noticeable when a carpet is laid on a floor made of a highly elastic material such as tatami mats.

For this reason, if an attempt is made to fix the problem by fixing the entire surface or wide back surface of the tile carpet to the floor surface using a strong adhesive, the advantage of the tile carpet as being freely removable will be lost.

The present invention was devised to solve these conventional problems.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a tile carpet formed by laying a plurality of carpet pieces adjacent to each other on the floor, a main carpet piece having a notch at a corner, and a main carpet piece having a notch in the corner. an interlocking carpet piece that engages with the main carpet piece at the notch (that is, engages with the main carpet piece so that it can be attached and removed in the vertical direction and cannot be attached and removed in the left and right directions), and is fixed to the lower surface of the engagement carpet piece,
A plate-shaped body having a larger area than the interlocking carpet piece.

[Effect]

In the present invention, by providing a notch in which another carpet piece, that is, an interlocking carpet piece engages, in the corner of the main carpet piece where the joining lines of the above-mentioned adjacent carpet pieces are concentrated at one point, the adjacent main carpet pieces can be connected to each other. The stretching pressure due to the pressing of the base material layer at the contact sides of the carpet pieces flows toward this notch where there is less resistance, so the pushing force generated at the joints between the main carpet pieces weakens, causing peeling and floating of the carpet pieces. does not occur. At the same time, floating that occurs in the center of the main carpet piece due to pressing forces does not occur because it reaches the notch where resistance is low and is dispersed and absorbed.

The interlocking carpet pieces interlock with the notches formed by the main carpet pieces laid adjacent to each other with a small amount of play due to the relationship between the sexes, and when pressed partially or intermittently, the five pieces interlock. It slides to the extent that you can't feel it and absorbs the pressure flowing towards this area.

Further, in the present invention, a plate-like member having a larger area than the interlocking carpet piece is fixed to the lower surface of the interlocking carpet piece. Therefore, the main carpet piece and the interlocking carpet piece are not only held by interlocking with each other, but also because the installed main carpet piece is placed on the plate-shaped body and pressed from above.
The main carpet piece and the interlocking carpet piece are held firmly.

By providing this wide plate-like body, when the floor structure is made of tatami mats or other highly elastic materials, the occlusal part is repeatedly moved up and down by pedestrians, causing the occlusal carpet piece to separate from the main carpet piece. Gradual free floating can be effectively prevented.

Therefore, in the present invention, the tile carpet can be laid in close contact with the floor surface without peeling or floating.
There is no need to use any special fixing means between the tile carpet and the floor surface.

By providing these plate-like bodies 8a to 8c, when the floor structure is made of tatami mats or other highly elastic materials, the occlusal part is repeatedly moved up and down by pedestrians, causing the occlusal part to move from the main carpet piece 1. It is possible to effectively prevent the carpet pieces 5a to 5c from gradually floating free.

Such an arrangement eliminates the need for special measures for fixing the carpet piece to the floor surface.

Furthermore, by using different colors for the main carpet piece 1 and the interlocking carpet pieces 5a to 5d of this embodiment, which are composed only of curved lines and have a beautiful design, it is possible to create a carpet that is composed only of conventional rectangular carpet pieces. Compared to traditional carpet tiles, you can create a variety of designs. Further, when the present invention is applied to a double-sided carpet, the design can be changed by turning over or replacing the whole or part of the carpet, so that a wide variety of designs can be created.

FIG. 5 is a plan view showing another shape of the interlocking carpet piece according to the present invention.

The shape of the occlusal carpet piece shown so far is a shape that avoids sharp corners and consists only of intricate curves suitable for intertwining, so that the stretching pressure due to the pressing force can be easily dispersed and absorbed, but this is just an example. It may be a shape in which the peripheral portion is a straight line, or a shape in which the peripheral portion is a curved line or a straight line.

6A and 6B show an example in which hook-and-loop fasteners 12 are provided on the plate-like body 8 in order to fix the main carpet piece placed on the plate-like body 8. In this way, the main carpet piece and the interlocking carpet piece are held more securely. In addition, Fig. 6A,
It goes without saying that this hook-and-loop fastener 12 may also be provided on a plate-shaped body composed of 3/4 and 1/2 of the plate-shaped body 8 of B.

FIG. 7 shows an example in which the interlocking carpet piece 5 is composed of interlocking carpet pieces 13a to 13d of different colors. By doing this, it is possible to create a wide variety of designs. It goes without saying that the interlocking carpet piece composed of 3/4 and 1/2 of the interlocking carpet piece 5 shown in FIG. 7 may also be composed of a plurality of interlocking carpet pieces.

Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to the above-mentioned embodiments, and that various modifications may be made within the scope of the claims for utility model registration.

In other words, the shape of the main carpet pieces was approximately square, but of course other shapes, such as polygons or shapes including curves, may also be used, and the main carpet pieces may be linear or curved.
Alternatively, they may be adjacent or occlusal in a straight line or a curved line.

Furthermore, various materials may be used for the carpet pieces, and although the main carpet piece and the interlocking carpet pieces are usually made of the same material, different materials may be used.

Furthermore, it is not always necessary to provide cutouts at the four corners of the main carpet piece; it is sufficient to use a main carpet piece that has cutouts appropriately provided from one corner to the four corners depending on the condition of the floor surface on which it is laid.

Furthermore, it goes without saying that the shape of the interlocking carpet piece is not limited to the above embodiment, and the shape of the peripheral portion of the interlocking carpet piece may be composed of a curved line, a straight line, or a curved line and a straight line.

Furthermore, in the above embodiments, the shape of the plate-shaped body is circular, but a circular shape is preferable because it can widely and evenly disperse the force applied from above partially. It is not limited.

[Effect of idea]

As explained above, the present invention can be applied to the corners of the main carpet piece where stretching pressure is likely to be concentrated due to partial or intermittent pressure applied by heavy objects such as furniture installed on the carpet and pedestrians. ,
Since the notch is formed, when the carpet is laid, the stretching force due to the pressing is dispersed and absorbed in the notch, so that peeling of one end of the carpet,
Effectively prevents floating or swelling in the center. In addition, since a plate-shaped body having a larger area than the interlocking carpet piece is fixed to the lower surface of the interlocking carpet piece, the laid main carpet piece is placed on the plate-like body and pressed from above, so that the main carpet piece can be pressed down from above. The carpet piece and the interlocking carpet piece are held firmly. With this configuration, the tile carpet can be maintained in tight contact with the floor surface. At the same time, if the floor structure is made of tatami mats or other highly elastic materials, this prevents the occlusal carpet piece from gradually floating free from the main carpet piece due to repeated up and down movements of the occlusal part by pedestrians. This can prevent the cleaner from getting caught or pedestrians from tripping.

Therefore, the wide plate-like body eliminates the need to directly fix carpet pieces to the floor surface, making it possible to lower installation costs and save labor. Carpets can be laid directly.

As described above, a notable effect of the present invention is that carpet tiles can be directly laid on highly elastic floor surfaces such as tatami mats, leaving the entire carpet surface with a soft feel due to the elasticity of the flooring material. As a result, the negative aspects of flooring material become a major positive side.

Furthermore, since the tile carpet of the present invention is composed of a main carpet piece and an interlocking carpet piece, it is possible to make both of them different colors, or to configure the interlocking carpet piece with a plurality of pieces of different colors. Therefore, the design can be varied and the aesthetic effect can be improved.

As explained above, the effects of the present invention are remarkable, and the advantages of tile carpets, such as being inexpensive and removable, can be fully utilized.
