DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beautiful staircase floor material used by being stuck on a staircase.

[0002]

2. Description of the Related Art Conventionally, a stair floor sheet made of synthetic rubber has been attached to a stair in order to reduce noise when climbing up and down the stairs and to improve slip resistance. However, synthetic rubber stair floor sheets cannot be firmly attached using an adhesive, so in recent years, synthetic rubber stair sheets have been replaced by synthetic resin staircases with excellent adhesive properties. Floor sheets have also been developed.

However, the conventional synthetic rubber stair floor sheet and the synthetic resin stair floor sheet are both non-patterned single-color sheets. For example, when they are attached to a wooden staircase of a wooden house, There was a problem in that the beautiful grain of the stairs was covered and obscured, resulting in poor appearance, and the stairs could not be harmonized with the surrounding wooden parts. Such a problem similarly occurs when the above-described stair floor sheet is attached to, for example, a stair in a stone-like building.

Therefore, the present applicant has developed a staircase flooring material in which the front edge of a composite sheet in which a pattern sheet is laminated and integrated on a synthetic resin sheet is bent downward by approximately 90 °, and has already filed an application ( Japanese Patent Application No. 9-344122). The floor material for the stairs was beautiful and harmonized well when attached to the stairs, with almost no fear of damaging the aesthetic appearance, but still had the following problems to be solved.

[0005]

That is, as described above,
The floor material for stairs, in which the front edge of the composite sheet obtained by laminating and integrating the pattern sheet on the synthetic resin sheet, is bent downward by approximately 90 °, the pattern sheet is relatively slippery, so there is a possibility that the foot may slip when ascending or descending, To prevent this, for example, approximately 90
° Even if you try to form anti-slip projections along the corners of the bent floor material by embossing, etc., it is difficult to form projections with large unevenness because the pattern sheet is laminated, and sufficient anti-slip There is a problem that the function cannot be exerted.

Moreover, in this staircase flooring, since the pattern sheets are also laminated at the corners of the flooring material which is most likely to be worn down by ascending and descending, the pattern sheets are worn out in a relatively short period of time and the lower side is worn. There was a problem that the synthetic resin sheet was exposed and the appearance was impaired.

[0007] In addition, when the floor material for stairs made of the above composite sheet is bent upward at the rear edge thereof and is stuck on the rise surface of the stairs, it is difficult to bend sharply, so the workability is not very good. In addition, there is a risk that the corners of the floor material cannot be seen in darkness such as during a power outage, and the stairs may be stepped off.

SUMMARY OF THE INVENTION The present invention has been made to address the above problems, and has as its object to exert a good anti-slip action, maintain aesthetics over a long period of time, and improve workability. Another object of the present invention is to provide a flooring material for stairs, which is favorable in that the corners of the flooring material can be visually recognized even in darkness.

[0009]

In order to achieve the above object, a floor material for a staircase according to claim 1 of the present invention has a front edge portion of a synthetic resin sheet bent downward at a substantially right angle to form a sheet corner portion. Along with forming the built-up portion, a projection group for preventing slippage is formed on the upper surface of the sheet along the built-up portion, and a pattern sheet is stuck and integrated on the upper surface of the sheet behind the protrusion group. Is what you do.

[0010] In the staircase flooring material having such a configuration, a good anti-slip action is exhibited by the anti-slip projections, and the padding prevents the seat corner from being worn out early.
Moreover, since the pattern sheet is stuck and integrated on the upper surface of the sheet behind the projection group and is not stuck to the sheet corner portion, the pattern sheet does not wear out in a short time in the corner portion unlike the conventional case. Good aesthetics can be maintained over a long period of time. In addition, as in the case of the floor material for stairs, when the pattern sheet is stuck on the upper surface of the sheet behind the projection group,
Since a group of projections having a large difference in unevenness can be easily formed by embossing, a good anti-slip action can be exhibited as described above.

[0011] In the floor material for stairs according to a second aspect of the present invention, in the floor material according to the first aspect, a notch groove for bending extending in the left-right direction is provided on the back surface near the rear end of the synthetic resin sheet. Is formed.

[0012] With such a floor material for stairs, the rear edge of the floor material can be easily and sharply bent upward along the cut groove, so that the rear edge of the floor material is stuck to the rise surface of the stairs. And the workability is improved.

[0013] In the flooring material for stairs according to claim 3 of the present invention, in the flooring material according to claim 1 or 2, a part or all of the sheet surface between the projections of the projection group is formed as a luminous surface. It is characterized by having done.

In such a staircase flooring, the light storage surface between the projections of the projection group emits light even in a darkness such as during a power failure, so that the corners of the flooring can be visually recognized.
No more worrying about stepping off the stairs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a floor material for stairs according to an embodiment of the present invention, FIG. 2 is a sectional view of the floor material for stairs, FIG. 3 is an enlarged partial perspective view of the floor material for stairs, FIG. Is a partial cross-sectional view of the pattern sheet of the floor material for stairs, and FIG. 5 is a cross-sectional view showing one construction example of the floor material for stairs.

The floor material A for stairs is composed of a synthetic resin sheet 1 and a pattern sheet 2 which form a floor material body.

The synthetic resin sheet 1 is made of an olefin resin such as polyethylene or polypropylene or a vinyl resin such as polyvinyl chloride as a base resin, and if necessary, a filler, a plasticizer, a coloring agent, a modifier, a reinforcing agent. A single-layer or double-layer sheet in which various physical properties have been improved by blending an
As shown in FIG. 3, the front edge portion 1a is bent downward at a substantially right angle by bending. A build-up portion 1b is formed at the sheet corner portion to form a front edge portion 1a.
And extends to near the lower end, as shown in FIGS. 1 and 3.
A drain groove 1c is formed between the built-up portions 1b. The overlaid portion 1b may be formed at least in the seat corner portion where stress is applied intensively when going up and down the stairs and is most likely to be worn and torn. As in the present embodiment, the overlaid portion 1b is formed near the lower end of the front edge portion 1a. You don't have to.

On the upper surface of the sheet, along the overlaid portion 1b, there are formed a group of projections in which a number of horizontally long rectangular anti-slip projections 1d are arranged. As shown in FIG. The sheet surface between the protrusions 1d is formed on the light storage surface 1e.

The above-mentioned overlaid portion 1b and each projection 1d of the projection group
Is formed by embossing the front edge portion 1a of the synthetic resin sheet 1 before bending it downward at a substantially right angle. Since the pattern sheet 2 is not attached, the embossability is good. And the difference between the irregularities is as large as 1 mm or more.

The luminous surface 1e can be attached with a luminous tape containing about 20 to 50% by weight of a luminous pigment (for example, trade name "Brillian Tolumi" manufactured by Toyo Sansho Co., Ltd.). It is formed by employing means such as applying a luminous paint containing a luminous pigment, and emits light in the dark.

Further, on the upper surface of the synthetic resin sheet 1 behind the projections, the pattern sheet 2 is bonded and integrated by means of bonding with an adhesive, thermocompression bonding, heat welding or the like. . As the pattern sheet 2, as shown in FIG.
A pattern printing film 2b having a pattern layer 2a printed on one side,
What laminated | stacked and laminated | stacked on the base film 2c so that the pattern layer 2a may become inside is used suitably. As the pattern layer 2a, a grain pattern that matches well with the wooden stairs,
A natural stone pattern that matches well with the stone staircase is suitable, and the pattern printing film 2b and the base film 2c are preferable.
Preferably, a film made of the same vinyl-based resin or olefin-based resin as the synthetic resin sheet 1 is used.

The staircase flooring material A having the above-described structure is shown in FIG.
As shown in FIG. 2, the adhesive is applied from the tread surface of the stairs 3 to the upper part of the rise surface with a commercially available floor adhesive 4 or the like. When the floor material A for stairs is attached in this manner, the beautiful pattern sheet 2 is laminated and integrated on the upper surface of the synthetic resin sheet 1 of the floor material A, so that the appearance is improved. When the pattern layer is a wood grain pattern or a natural stone pattern, the appearance is improved in harmony with the steps of a wooden house or the steps of a stone-like building. The pattern sheet 2 does not wear out at the corners of the floor material as early as the conventional pattern sheet, so that the appearance can be maintained for a long time.

In addition, the stair flooring material A exhibits a good anti-slip effect due to the anti-slip projections 1d having a large difference in unevenness, so that there is no danger of slipping the foot when ascending or descending. The luminous surface 1e emits light even in the dark of time,
As a result, since the seat corners of the floor material A can be visually recognized, the danger of stepping off the stairs even in darkness is eliminated. Then, the overlaid portion 1b prevents the seat corner portion, which is most likely to be worn away, from being worn out early, so that the durability is greatly improved.

FIG. 6 is a partially enlarged sectional view showing a floor material for stairs according to another embodiment of the present invention.

The staircase flooring material B has a front-rear dimension larger than that of the flooring material A, and has a bending section V extending in the left-right direction on the back surface near the rear end of the synthetic resin sheet 1.
A plurality of notch grooves 1f are formed. Other configurations are the same as those of the floor material A, and therefore, the same reference numerals are given to the same members in FIG. 6, and the description will be omitted.

The floor material B for stairs is provided with the cut grooves 1
Since the rear edge of the flooring material can be easily and sharply bent upward as shown by a dashed line along f, when the rear edge of the flooring material is to be adhered to the rising surface of the stairs, the sticking work is performed. This has the advantage that the workability is improved and the workability is improved.

[0028]

As is clear from the above description, the flooring material for stairs of the present invention can form a group of projections having a large difference in unevenness by embossing or the like, so that it can exhibit a good anti-slip effect, and furthermore, can provide a pattern sheet. Is not worn away early, so that the appearance can be maintained for a long period of time. Also, the build-up prevents the corners of the seat from being torn, so that the durability is improved. However, since the corners can be visually recognized, the safety is further enhanced, and in addition, the one having the cut grooves has many remarkable effects such as easy to bend the rear edge of the flooring material to improve the workability.
