Description

[Detailed Description of the Invention] This invention relates to a tile made of synthetic resin or rubber suitable for laying on a floor surface on which a flat cable is arranged.

In recent years, there has been a significant trend toward office automation, and as a result, cases in which a large number of cables are present on the floor are increasing. Such cables not only spoil the aesthetics but also pose safety problems such as tripping and injury. Therefore, a system called a raised floor has been devised to store these cables under the floor. Although this method can solve the above problems, it has disadvantages such as raising the floor surface, reducing the amount of indoor space that can be used effectively, and increasing the cost of construction methods and materials. In addition, flat cables are placed above the floor and a carpet is placed on top of the flat cables. In that case, there was a restriction that carpet or carpet tiles had to be used as the floor finishing material. The reason for this is that flat cables are also somewhat thick, and if a synthetic resin floor tile is laid on top of it, that part will swell and spoil the aesthetics, so we use carpet to make the swell (step) less noticeable with carpet pile. It is to let it happen. However, carpets are expensive, and because they do not essentially eliminate differences in level, they pose a problem in moving office equipment with casters.

Therefore, in order to essentially eliminate this difference, Jikaisho
Carpet tiles such as No. 58-141043 have also been proposed. This involves making a cut in the backing layer that reaches the fiber layer, removing only the backing layer, and storing the flat cable in that part. According to this method, it is true that the level difference caused by the flat cable can be essentially eliminated. However, this Japanese Utility Model Application No. 58-141043 is still a carpet, which is expensive and its use is restricted due to hygienic reasons such as the occurrence of dust mites and the adhesion of dust.

Further, if the above-mentioned partial removal structure of Utility Model Application No. 58-141403 is directly applied to a floor tile having an abrasion-resistant surface layer as in the present invention, the following disadvantages occur.

Flat cables are not standardized and come in various thicknesses. Therefore, if there is a difference between the thickness of the backing layer to be removed and the thickness of the flat cable, a portion of the tile may be raised or a space may be created between the top surface of the flat cable and the tile. . In the case of carpet tiles, piles or fibers are planted in the base fabric to form a flexible and bulky fabric surface layer, so the carpet tiles do not conform to the top surface of the flat cable. The space disappears, and the surface of the carpet tile does not become depressed or dented. Also,
Even if there is some bulge, it is not noticeable, and the bulge is absorbed by the height (thickness) of the planted piles or fibers, so it does not interfere with the movement of the caster.

In contrast, synthetic resin or rubber floor tiles with an abrasion-resistant surface layer are flexible but not as flexible as carpet tiles, and do not have bulky piles or embedded fibers. . Therefore, if the thickness of the backing layer to be removed is thinner than the thickness of the flat cable, the surface will be raised, which will not only be noticeable in appearance, but also be easily soiled and damaged, and will also become an obstacle to the movement of the caster.
Although it is conceivable to set the thickness of the backing layer to be removed sufficiently large so as to accommodate flat cables of various thicknesses, new disadvantages arise in this case. That is, depending on the thickness of the flat cable, a space may be created between the top surface of the flat cable and the tile, and the tile may cave in at this portion. In this way, synthetic resin or rubber floor tiles with a wear-resistant surface layer are
It does not have the flexibility of carpet tiles, and if unnecessary space is formed on the flat cable, it will collapse due to the weight of walking, spoiling its aesthetic appearance.

This proposal solves the above-mentioned problems and provides a floor tile with a wear-resistant surface layer that is inexpensive, sanitary, and can easily eliminate the level difference caused by the flat cable.

That is, this invention provides a synthetic resin or rubber floor tile consisting of an abrasion-resistant surface layer, an intermediate layer, and a backing layer, with a plurality of easily peelable layers spaced apart from each other between the backing layer and the intermediate layer or inside the backing layer. The object of the present invention is to provide a floor tile for flat cable wiring, which is constructed so that the backing layer can be peeled off relatively easily to obtain a plurality of desired thicknesses.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a sectional view showing an embodiment of the floor tile according to this invention. The floor tile 1 basically consists of a wear-resistant surface layer 2, an intermediate layer 3, and a backing layer 5, 5'. The wear-resistant surface layer 2 is made of a compound with a relatively large amount of resin in order to increase durability against walking etc., and is made of a synthetic resin sheet or a sheet-like material obtained by heating and sintering synthetic resin powder. used. When this wear-resistant surface layer is transparent or translucent, a printed layer may be interposed between the wear-resistant surface layer and the intermediate layer. Also, middle class 3
is provided for the purpose of reducing the cost of floor tiles, preventing warping of the surface layer, imparting various types of mechanical strength, and, as will be described later, to prevent the backing layer from caving in when a portion of the backing layer is partially removed. It is something that Therefore, this intermediate layer must be made of a material that is a little harder than the surface layer, and the amount of resin must be less than that of the surface layer. It is also preferable to reduce the amount of resin in the backing layer. In addition, this backing layer is
It is better to make it softer than the middle layer when cutting,
Convenient for removing cut parts.

Next, in the present invention, an easily peelable layer is provided between the middle layer and the backing layer or inside the backing layer of the floor tile having the basic three-layer structure as described above. and the backing layer 5 and the backing layer 5,
Easily peelable layers 4 and 4' are provided at two locations between the layers 5' (inside the backing layer), respectively. This easily peelable layer is
Any material may be used as long as the backing layer can be peeled off relatively easily (without breaking the backing layer during peeling). Examples of this easily peelable layer include a tacky adhesive and a polyolefin resin. Of course, the material is not limited to these, and various materials can be used depending on the material of each layer used in the floor tile. To lay the floor tile of the present invention on a flat cable floor, cut a cut from the backing layer side to the easy-peel layer in line with the width of the flat cable at the point where the floor tile contacts the flat cable. All that is required is to peel off the backing layer to form a notch and store the flat cable in the notch.

At this time, depending on the thickness of the flat cable, if a thick flat cable is used, the easy peel layer 4
The backing layers 5 and 5' are both peeled off and removed to form a deep notch. On the other hand, in the case of a thin flat cable, the cutting depth is set to the easily peelable layer 4', and only the backing layer 5' is peeled off to form a shallow notch.

As mentioned above, this invention uses synthetic resin floor tiles that can be used with flat cables, so they are extremely inexpensive compared to conventional carpet tiles, easy to clean, and hygienic. The benefits are great, such as being able to move things around smoothly.

In addition, since the depth of the notch can be adjusted according to the thickness of the flat cable, it is possible to prevent unnecessary spaces from forming between the top surface of the flat cable and the floor tile. Not only does it prevent sinks and dents, giving it an excellent appearance, it also makes it easier to move office equipment with casters.
