DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor sheet used by being attached to a stair.

[0002]

2. Description of the Related Art Conventionally, in order to reduce noise when climbing up and down stairs and to improve slip resistance, a synthetic rubber made of synthetic rubber having a convex surface on the tread surface of the base of the stair or from the tread surface to the rising surface. Alternatively, a synthetic resin floor sheet is attached with a rubber-based adhesive or adhesive.

[0003]

However, most of the conventional floor sheets for stairs are not flattened to the back side by about 90 ° in advance, and therefore, are generally 90 ° to the back side at the construction site.
It is necessary to stick to the rise from the tread surface of the stairs while bending, and this sticking work is troublesome, and since the returning force acts at the bent part of the floor sheet, the floor sheet often rises at the rise part after sticking work There was a problem of peeling.

[0004] Furthermore, most of the conventional floor sheets for stairs have the same color in their entirety, so when they are bent at approximately 90 ° and affixed to the stairs, the bent portions (corner portions of the stairs) stand out. It was difficult, and there was a danger that those who went up and down the stairs would step off. In addition, since the bent portion of the floor sheet is easily worn and stress due to treading is likely to concentrate, there is a problem in durability such as breakage in a relatively short period of time, and there is also a problem in that the floor sheet is slippery.

The present invention has been made to solve the above-mentioned problems.

[0006]

In order to achieve the above object, a floor sheet according to a first aspect of the present invention is a floor sheet to be stuck on a staircase, and is bent approximately 90 ° on the back surface side. On the surface of the bent portion of the synthetic resin base sheet, a perforated sheet made of synthetic resin having a color difference of 5 or more from the base sheet is embedded and integrated, and each hole of the perforated sheet is integrated. Through which the synthetic resin of the base sheet is exposed on the surface.

[0007] The floor sheet having such a configuration has a bent portion, which makes it extremely easy to attach the stairs to the base of the stairs, and after the attachment, the corner portions of the stairs become more easily visible. It is also possible to enhance the design by combining the hues of the material sheet and the perforated sheet.

The floor sheet having such a structure has approximately 9
Since it has a bent portion bent at 0 °, a troublesome work of bending the floor sheet when attaching the floor sheet to a stair like a conventional floor sheet becomes unnecessary, and the work of attaching the floor sheet to the stair can be performed easily. Then, since the returning force does not act on the bent portion of the floor sheet after pasting, the floor sheet does not peel off at the rising portion. Moreover, since the perforated sheet has a color difference of 5 or more from the base sheet, the bent portion of the sheet (the corner of the stairs) in which the perforated sheet is buried is conspicuous and the bent portion can be clearly seen. Therefore, there is less danger of stepping off when climbing up and down, and the appearance is improved.

A floor sheet according to a second aspect of the present invention is the floor sheet according to the first aspect, in which the synthetic resin of the base sheet is raised to the surface through each hole of the perforated sheet to form the overlay. It is characterized by having been formed.

In the floor sheet having such a configuration, the anti-slipping property is enhanced by the built-up portion, and it is difficult to slip when going up and down the stairs, so that the safety is improved. In addition, since the thickness of the bent portion of the sheet is increased and reinforced by the built-up portion, the fear that the bent portion of the sheet is worn and damaged early is eliminated, and the durability is improved. In addition, since the rainwater that falls on the tread of the floor sheet is quickly drained downward through the recessed portion between the overlays, there is no danger that rainwater or the like will accumulate on the tread of the floor sheet and become slippery. .

Further, in the floor sheet according to the third aspect of the present invention, in the floor sheet according to the first or second aspect, an extending portion extending rearward from a rear end portion of the tread surface of the base sheet is coupled. At least one notch is formed on the back surface of the base sheet along the rear end of the tread surface.

In the floor sheet having such a structure, the extended portion of the base sheet can be easily bent upward at the cut groove, and the bent extended portion can be bent one step above the stairs. By sticking it to the riser and joining it with the riser of the floor sheet on the next higher level, the entire surface of the stairs can be covered and the appearance can be enhanced. If there is an unnecessary portion in the extension portion, it can be easily cut and removed along the cut groove.

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 partial plan view of a floor sheet according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a partial front view of the floor sheet.

As shown in FIG. 2, the floor sheet 1 is used by attaching an adhesive or the like to a tread surface 41 of each step of the stairs 4 and an upper part of a riser 42. As shown in FIG. 3, the front edge 21 of the rectangular base sheet 2 made of synthetic resin is bent downward at approximately 90 °, and the surface of this bent portion is bent at approximately 90 ° on the synthetic resin. A band-shaped perforated sheet 3 made of steel is embedded and integrated. Then, the base sheet 2 is raised and exposed to the surface through the holes 31 and 32 of the perforated sheet, and the overlay portions 22 and 23 are formed.

The base sheet 2 is made of a simple resin such as a vinyl resin such as polyvinyl chloride, an olefin resin such as polyethylene or polypropylene, an ester resin such as unsaturated polyester, or an amide resin such as nylon. Alternatively, it is a sheet having a single-layer structure or a laminated structure made of a mixture or a material obtained by appropriately mixing an inorganic filler, a fibrous reinforcing material, rubber, and the like with the mixture. On the upper surface of the base sheet 2 serving as a tread surface, a small convex pattern 24 for preventing slippage is provided.
However, vertical ribs 25 for preventing warpage are formed at the lower end of the front surface of the bent front edge 21 of the base sheet to be raised.

The perforated sheet 3 is also made of a single or a mixture of the same synthetic resins as described above, or a material obtained by appropriately blending an inorganic filler, a fibrous reinforcing material, rubber and the like. The perforated sheet 3 is colored so that the average color difference from the base sheet 2 is at least 5 levels, preferably at least 50 levels, so that the bent portion in which the perforated sheet 3 is embedded is conspicuous. , Clearly visible. Therefore, there is no danger of overlooking the bent portion of the floor sheet when stepping up and down the stairs and stepping off the foot, thus improving safety. Further, even if the color of the perforated sheet 3 and the color of the base sheet 2 are similar colors, if there is a difference of 5 or more in brightness, it can be similarly identified by the color difference. Then, when a fluorescent substance is contained on the surface of the perforated sheet 3 or a fluorescent paint is applied, it is possible to drastically reduce the number of steps in the dark.

FIG. 4A is a partial plan view showing the flat perforated sheet 3 before being bent along the dotted line,
Holes 31 for forming a horizontally long overlay portion are formed in an arrangement pattern arranged vertically and horizontally on a portion to be a tread surface above the dotted line, and a portion which is slightly raised from a portion above the dotted line and becomes a lower kick-up portion. Are formed with holes 32 for forming a vertically elongated overlay portion in parallel at regular intervals.

When such a perforated sheet 3 is overlapped with a bent portion of the synthetic resin base sheet 2 softened and melted by heating, and simultaneously buried and integrated by pressing, it is simultaneously bent.
Under the pressure, the base sheet 2 in the softened and molten state becomes the perforated sheet 3
As shown in FIG. 1 to FIG. 3, a horizontally long cladding portion 22 is formed in an array pattern arranged vertically and horizontally on the tread surface as shown in FIGS. The floor sheet 1 in which the vertically extending overlay portions 23 are formed in parallel at the riser portion is manufactured.

As described above, the overlay portions 22 and 23 correspond to the floor sheet 1.
The bent portions 22 and 23 increase the thickness of the bent portions of the floor sheet and are reinforced by the built-up portions 22 and 23. Therefore, there is no fear that the bent portions are worn and damaged early, and the durability is reduced. improves. In addition, since the anti-slip property is enhanced by the horizontally extending overlay portion 22, slipping is hardly caused at the bent portion of the floor sheet 1 during ascent and descent, and safety is further improved. Further, rainwater or the like that has poured onto the tread surface of the floor sheet 1 is quickly discharged downward through the depressions 26 between the vertically extending overlay portions 23, so that rainwater or the like accumulates on the tread surface of the floor sheet 1. There is no danger of slipping. Holes 31 and 32 of perforated sheet 3
Can be formed in a desired shape and arrangement pattern. FIGS. 4B and 4C show another example of the perforated sheet. In the perforated sheet 3 of FIG. 4B, holes 31 for forming a horizontally long overlay are arranged in a staggered pattern. The holes 32 are formed in a pattern, and the holes 32 for forming the vertically elongated overlay are formed in parallel. Further, the perforated sheet 3 of (c) is formed by forming an array pattern in which holes 31 for forming a slightly short horizontally long overlay portion are aligned vertically and horizontally, and a hole 32 for forming a vertically long overlay portion. Are formed in parallel, and a hole 32 for forming a vertically long overlay portion has an open lower end and a semi-elliptical upper end as shown in the figure. When the upper end of the hole 32 has a semi-elliptical shape, the upper end of the vertically extending cladding portion 23 protruding through the hole 32 also has a semi-elliptical shape, and the tread surface of the depression 26 between the cladding portions 23 is formed. Since the width of the side end is increased, the drainage of the recess 26 is improved. still,
Only one of the holes 31 or 32 may be formed in the perforated sheet 3.

Although the floor sheet 1 of this embodiment has the overlaid portions 22 and 23 formed as described above, the floor sheet 1 is exposed on the surface without raising the base sheet 2 from the holes 31 and 32 of the perforated sheet 1. You may make it do. In the floor sheet 1 of this embodiment, the perforated sheet 3 is embedded in the bent portion of the base sheet 2 so that the surface of the base sheet 2 and the surface of the perforated sheet 3 are flush. Alternatively, the perforated sheet 3 may be embedded such that the surface thereof is lower or higher than the surface of the base sheet 2.

FIG. 5 is a sectional view of a floor sheet according to another embodiment of the present invention.

The floor sheet 1 is provided with an extended portion 27 extending rearward from the rear end of the tread surface of the base sheet 2 and is cross-sectionally formed on the back surface of the base sheet along the rear end of the tread surface. A V-shaped cut groove 28 is formed. The cut groove 28 is formed in the extension 2
7 may be formed on the back surface, and the cross-sectional shape may be various shapes such as V-shaped and U-shaped. Other configurations are the same as those of the floor sheet 1 of the above-described embodiment, and therefore, the same reference numerals are given to the same members in FIG. 5, and description thereof will be omitted.

In such a floor sheet 1, the extension 27 of the base sheet 2 can be easily bent upward at the cut groove 28, and the bent extension 27 is placed one step above the stairs. By attaching to the rise of the next step and joining with the rise of the floor sheet of the next step, the entire surface of the stairs can be covered to enhance the beauty. If there is an unnecessary portion in the extension portion 27, it can be easily cut and removed along the cut groove 28.

[0025]

As is clear from the above description, the floor sheet of the present invention can be easily attached to the stairs, does not have to be peeled off from the riser portion after application, and has a color difference of 5% from the base sheet. Since the bent portion of the floor sheet is more conspicuous due to the perforated sheet having a level higher than the standard, it is possible to prevent the stepping out of the floor sheet when going up and down stairs, and it is possible to use the apparatus safely for a long time.

The base sheet protruding from the surface of the perforated sheet through the holes to form a built-up portion has improved anti-slip properties at the bent portion of the floor sheet and good drainage. The danger of falling due to slips, etc. is drastically reduced, and the bent portion of the floor sheet is thickened and strengthened by the built-up portion. This has the effect of improving the performance.

Furthermore, the base sheet provided with the extended portion on the base sheet to form the cut groove can continuously cover the entire surface of the stairs to enhance the aesthetic appearance, and can easily cut unnecessary portions along the cut groove. This has the effect that it can be performed in a short time.
