Description

TECHNICAL FIELD The present invention relates to a flooring material mainly composed of a flexible material such as synthetic resin.

2. Description of the Related Art Conventionally, a plurality of floor materials are laid on the same floor for the purpose of design effect and functionality. For example,
In stores such as department stores, floor materials of different materials and colors are laid on one floor to distinguish the aisle from the sales floor, and even in the sales floor, the floor material color and materials can be changed on an individual sales floor unit basis. We are creating a space tailored to.

In such a case, the sales floor may be consciously raised with respect to the aisle, or a step may occur due to a difference in the type of floor material without being aware of it. In particular, recently, a stationary floor material has been developed, which is used by simply placing the floor material without adhering to the floor base. Particularly in stores and the like, efforts are often made to change the image (atmosphere) of the sales floor to attract the interest of customers. In such places, a floor-standing type floor material that can be easily replaced is suitable. This floor mat (tile) is
From the viewpoint of preventing deformation, warpage, turning over, movement, etc., it is formed with a thickness of, for example, about 4 to 8 m / m, so that the difference in level from the conventional thin tile attached with an adhesive is more prominent. Has become. If there is a step, there is a risk of tripping, so conventionally, a parting bar or joint material was applied to the step to prevent this. FIG. 4 is a cross-sectional view showing this state, in which a metallic parting bar 39 is fixed to the step portion between the thick floor tile 35 and the thin floor tile 37 to eliminate the step portion.

However, the use of the parting bar 39 leads to an increase in cost due to its own price and construction cost. In addition, a screw or the like used for fixing the parting bar 39 may become a new metallic projection, or the parting bar 39 may be too conspicuous to give an unnatural impression.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention provides a flooring material that prevents the occurrence of a step at the boundary even when it is laid in contact with a thin flooring material and that can be constructed with smoothness. It is a thing.

Configuration of the Invention The flooring material of the present invention is made of a flexible material as a whole, and the back side is tapered at the end, and the width is narrowed from the back side to the front side at or near the base of the tapered portion. The groove is formed on the back surface of the floor material so as not to reach the front surface of the floor material.

Example FIG. 1 is a cross-sectional view showing the vicinity of an end of an example of a flooring material of the present invention, and shows a case where the flooring material is applied to a plastic floor tile of a floor-standing type. 1 to 3 are sectional views, they are not hatched for convenience of illustration.

The floor-standing thick floor material 11 has a thickness of about 4 to 8 m / m (typically 5.5 m / m) as a whole, and has a laminated structure of a support layer 13 and a surface layer 15. . The support layer 13 is formed of a synthetic resin such as a vinyl chloride resin filled with a relatively large amount of filler in order to have a weight. The surface layer 15 is provided with a decorative effect and abrasion resistance, and is also made of a synthetic resin such as vinyl chloride resin. As described above, the floor material 11 is mainly formed of synthetic resin and has flexibility or softness as a whole.

At the end of the floor material 11, the back side is cut diagonally and the taper
Forming 17. Further, at the base of the tapered portion 17,
A groove 21 having a substantially V-shaped cross section whose width becomes narrower from the back surface side to the front surface side is provided along the end surface of the floor material 11 at a depth that does not reach the surface layer 15.

FIG. 2 is a sectional view showing a construction example of the floor material 11 shown in FIG. A thin floor material 33 is laid on the floor base 31.
Push the thick floor material 11 so that the end surface of the thick floor material 11 is brought into contact with the end surface of the thin floor material 33.
Since 11 has flexibility, it deforms so that it fits in the thin floor material 33 and the floor base 31, and both walls of the groove 21 stick to each other so that the groove 21 disappears. "Is suitable. In addition, 23 shows a groove mark. As described above, it is possible to lay floor materials having different thicknesses without generating a step without using another member such as a parting bar. By preparing several kinds of flooring materials having different sizes of the taper portion 17 and the groove 21, it is possible to correspond to combinations with all thin flooring materials. Further, since the floor material 11 has flexibility and the groove 21 disappears to absorb the strain caused by the deformation, there is some degree of tolerance, and it is not necessary to prepare so many types.

Further, since the groove 21 disappears and the strain due to the deformation can be absorbed, a natural curve can be obtained in the vicinity of the end of the floor material 11, and a natural laying between floor materials can be realized with a good look.

It is not always necessary to completely eliminate the groove 21 during construction, but by attaching both walls of the groove 21 and completely eliminating the groove 21, it is possible to prevent a cavity from remaining inside the floor material 11. Therefore, the strength of the floor material 11 against the load can be made strong.

Although FIG. 1 shows the case where the groove 21 is formed from the base of the taper portion 17 to the left side in the drawing, a part of the groove 21 is formed in the taper portion.
It may be formed to extend over 17. Moreover, by forming a plurality of grooves 21, it is possible to further improve the smoothness in the vicinity of the end portion of the floor material 11. In this case, the groove may be formed in the tapered portion 17, or may be formed in a portion on the left side of the groove 21 in FIG. 1 where the floor material has a uniform thickness.

FIG. 3 is a cross-sectional view showing another embodiment of the present invention. In order to make the contact with the end surface of the thin floor material 33 smoother, the taper portion 19 is also provided on the surface side of the end portion of the floor material 11. The flooring material provided with is shown. It is preferable that the groove 21 and the taper portions 17 and 19 have the same angle (θ in FIG. 3) so that they can fit neatly.

In the above embodiments, the floor tile of a two-layer structure type floor tile was described as an example, but the structure, material, type, etc. of the floor material are not limited to this, and for example, a single-layer type or floor layer tile is also available. Floor materials other than floor tiles may be used. The floor material may or may not be adhered to the floor base.

The taper portion and the groove of the floor material may be previously formed and shipped at the time of manufacturing the floor material, or may be formed by a cutter or the like at the time of construction at the site.

Effect of the Invention According to the floor material of the present invention, a taper portion is provided on the back surface of the end portion of the floor material.
Also, by forming a groove on the back surface of the base of the tapered portion or in the vicinity thereof, the width of which narrows toward the surface, so that a step is generated at the contact portion even when laying in contact with a thin floor material. It is possible to prevent that, tripping can be prevented. Also, since the parting bar is unnecessary, cost reduction can be realized, and metal protrusions such as screws are not necessary for fixing,
Widely applicable to the integration of various floor materials. Furthermore, since the contact part has a good look, natural integration is possible,
The decorative effect and functional effect can be further enhanced.
