Abstract

PROBLEM TO BE SOLVED: To provide a beautiful pattern by molding a composite sheet by integrally laminating a pattern sheet on a synthetic resin sheet, and superposing the pattern sheet on a backing film so that a printing surface of a pattern printing film becomes inside. SOLUTION: A floor material A for stairs is molded by downward bending a front edge part 1a of a composite sheet 1 by integrally laminating a pattern sheet 12 on a synthetic resin sheet 11 by almost 90 deg.. Antislipping square projections 21 and paper strip-shaped projections 22 are formed in large numbers by an embossing finish on an upper surface of this floor material A for stairs, and a cladding part 3 is formed over the front edge part 1a from a corner part. The pattern sheet 12 is also laminated by superposing a pattern printing film by printing a pattern such as a grain pattern and a natural stone pattern on one surface, on a backing film so that a pattern printing surface becomes inside. Therefore, durability can be improved by holding a beautiful pattern over a long period.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[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 enhance slip resistance.

However, synthetic rubber floor sheets for stairs are
In recent years, a synthetic resin stair floor sheet having high adhesive strength has been developed instead of a synthetic rubber stair floor sheet because it cannot be firmly stuck with an adhesive.

[0004]

However, the conventional synthetic rubber stair floor sheet and the synthetic resin stair floor sheet are both non-patterned single-color sheets. When attached to the stairs, there was a problem that the beautiful grain of the stairs was covered up and the appearance became poor, and the stairs and the surrounding wooden parts could not be harmonized.

[0005] Such a problem similarly occurs when the above-mentioned staircase floor sheet is attached to, for example, a staircase of a stone building.

[0006] The present invention has been made to address such a problem, and its object is to provide a beautiful pattern,
An object of the present invention is to provide staircase flooring materials that are in harmony with the steps of a wooden house or the steps of a stone-like building and do not impair the aesthetic appearance.

[0007]

In order to achieve the above object, a stair flooring material according to the first aspect of the present invention is a method of manufacturing a stair flooring, comprising: It is characterized by being bent downward by approximately 90 °.

The staircase flooring material according to claim 2 is the staircase flooring material according to claim 1, wherein the pattern sheet is formed by superimposing the pattern printing film on the base film so that the printing surface is inside. The stair flooring material according to claim 3 is characterized in that the pattern sheet has a wood grain pattern or a natural stone pattern in the stair flooring material according to claim 1 or 2. Things.

The staircase flooring of the first aspect has a pattern sheet on the surface, so that it does not impair the aesthetic appearance when attached to the stairs. In particular, the pattern sheet has a wood grain like the staircase flooring of the third aspect. When it has a pattern or a natural stone pattern, it is well harmonized when applied to stairs of a wooden house, stairs of a stone-like building, or the like, and appearance is improved.

Further, in the flooring material for stairs according to the second aspect, the inner pattern printing surface does not wear until the pattern printing film is worn out,
Since a beautiful pattern can be maintained for a long period of time, the durability is good.

[0011]

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 cross-sectional view of the floor material for stairs, FIG. 3 is a partial cross-sectional view of a pattern sheet of the floor material for stairs, FIG. 4 is a cross-sectional view showing a use state of the floor material for stairs.

As shown in FIG. 2, the floor material A for stairs is obtained by bending a front edge 1a of a composite sheet 1 in which a pattern sheet 12 is laminated and integrated on a synthetic resin sheet 11 downward by approximately 90 °. As shown in FIGS. 1 and 2, a large number of rectangular projections 21 and strip-shaped projections 22 are formed on the upper surface by embossing.

By forming the overlay 3 from the corner of the floor material A for stairs to the front edge 1a,
When the floor material A is used by being stuck on the stairs, the corner portion is worn away early so that it is not broken, and the front edge 1a is prevented from turning up from the rising surface of the staircase.

The composite sheet 1 is made of a synthetic resin sheet 11 by using means such as thermocompression bonding, heat fusion, or bonding with an adhesive.
The synthetic resin sheet 11 is made of a thermoplastic synthetic resin, for example, a vinyl resin such as polyvinyl chloride or an olefin resin such as polyethylene as a base resin. A sheet having a single-layer structure or a laminated structure of two or more layers produced by using a material in which an inorganic filler such as calcium carbonate or the like, various additives, modifiers, and the like are blended therein is preferably used.

As shown in FIG. 3, a pattern printing film 122 having a pattern 121 such as a grain pattern or a natural stone pattern printed on one side is used as the pattern sheet 12, and a base film 123 such that the pattern printing surface is on the inside. What is laminated and is preferably used. Pattern printing film 1
The resin film 22 or the base film 123 is preferably a resin film made of a vinyl-based resin or an olefin-based resin having good thermocompression bonding property and heat fusion property to the synthetic resin sheet 11.

In addition, as the pattern sheet 12, a sheet having a color-coded pattern formed over the entire thickness of the sheet can be used in addition to the above.

The floor material A for stairs having the above-mentioned structure is prepared by extruding a synthetic resin containing an inorganic filler from an extruder and sheeting, stacking a pattern sheet 12 on the synthetic resin sheet 11 and heating the sheet. It can be easily manufactured by performing embossing at the same time as crimping and bending the front edge 1a.

As shown in FIG. 4, the stairs flooring material A is used from the tread surface of the stairs 4 to the upper part of the rising surface with a commercially available flooring adhesive 5 or the like. Even if the floor material A for stairs is stuck in this way, the beautiful pattern sheet 12 is laminated and integrated on the surface, so there is no fear of impairing the aesthetic appearance. If it is, the appearance is improved in harmony with the steps of the wooden house or the steps of the stone-like building.

The floor material A for stairs is a pattern sheet 1
Since the printed surface of the inner pattern 121 is not worn until the second pattern printed film 122 is worn out, and the thicker the pattern printed film 122 is, the more beautiful the pattern 121 can be retained over a long period of time. It is also possible to improve the durability by increasing the thickness.

Since the stair flooring A has the built-up portion 3 as described above, the corner portion is not worn away at an early stage and is not torn. There is no need to worry about peeling off the riser. In addition, since the anti-slip projections 21 and 22 are formed on the upper surface, there is no danger of slipping and falling over when ascending and descending, which is safe.

[0022]

As is clear from the above description, the flooring material for stairs of the present invention has a pattern sheet laminated and integrated on its surface, so that it does not impair the aesthetic appearance when stuck on stairs.
In particular, when the pattern of the pattern sheet is a wood grain pattern or a natural stone pattern, it is well harmonized when pasted on a stair of a wooden house or a stair of a stone-like building, and the appearance is good, and the durability is also good. There is an effect that there is.
