Description

[Detailed Description of the Invention] The present invention relates to a carpet to be laid on the tread surfaces and front edge corners of stairs that have been used for a considerable number of years and are severely worn and damaged, or that are newly constructed.

In the past, it was extremely difficult to renovate or repair only the stairs, and for stairs that had been used for many years and were severely damaged, methods were limited to repainting them or laying carpets on the entire surface.

In addition, in the case of a new construction, if the tread metal surface is covered with carpet etc., an inexpensive wooden board with no surface treatment can be used, but if even a portion of one of the tread plates is exposed, the wood or surface treatment of the tread surface should be changed. Must be considered.

In addition, the conventional technology for stair carpets is to cut carpet or rubber into the shape of a tread and attach it using a latch hook. It requires complicated work such as attaching metal fittings on the side in a narrow space, and it cannot be used for box-shaped stairs that are commonly used.

The present invention is aimed at allowing staircases to be renovated or newly installed easily and inexpensively in an extremely short period of time without the need for tools or metal fittings.Examples of the invention will be described below with reference to the drawings.

In Fig. 1, a synthetic resin film 1 made of vinyl chloride or the like printed, embossed, or coated with the grain of natural wood, the texture of textiles, the striped pattern of marble, or any other pattern is glued or fused, or directly Thickness 3-7rIrI printed with the above-mentioned pattern! Approx. width 60-80c11 made of synthetic resin such as L vinyl chloride or rubber, with moderate flexibility
The substrate 2 has a rectangular, trapezoidal or triangular shape and has a depth of t1 of 20 to 40 Crn.

Reference numeral 3 denotes a carpet made of natural yarn or synthetic fiber in a desired shape, such as a rectangular or oval shape, which is sewn or fused to the substrate 2.

As shown in the cross-sectional view in FIG. 2-1, the board 2 extends from one end to a portion corresponding to the front edge corner of the tip of the stairway, and slopes gently upward with respect to the horizontal plane of the stair tread over a length of 3 to 7 crft. and the center line 1) shown in Figure 1 -
At a point beyond D', the slope decreases rapidly, and the back surface of this part has a V-shaped groove.

Then, by vertically bending the front part of the substrate downward at the center line [) -D' using a heat press, the front edge corner part 3' of the carpet is formed, and the cross section shown in Fig. 2-2' is obtained. be able to.

At this time, since there is a V-shaped groove on the back side, it is easy to bend, easy to heat press, and has a good finish.

The rims are also beautiful.

Moreover, if the material of the board 2 and the depth of the V-shaped groove are appropriately set, no special heat press processing is required, and if the board 2 is placed on a stair tread, the front edge of the board 2 will fold automatically at the V-shaped groove. bend,
It is also possible to form a carpet leading edge corner 3'.

As shown in the installation example shown in Fig. 3, the front surface of the board is brought into close contact with the front surface of the stair tread, and the board 1 is placed between A-A' and B according to the dimensions of the stair tread.
By cutting along the line -B' or C-C', it can be easily laid over the entire surface of the stair tread without any gaps.

Therefore, since the portion to be cut and cut is not the expensive carpet 3 but an inexpensive patterned synthetic resin substrate, the cost of loss due to being cut and unusable can be kept to a minimum.

This project has the structure as described above, and can be laid on the entire surface of the tread and the corner of the front edge, and can be laid on the entire surface of the staircase except for the stairwell, making it ideal for stairs in second-hand houses with wear and tear. Also, since all of the newly built stairs are hidden, there is an advantage that cheap wood can be used instead of high-quality wood, and cleaning is easy because there are no gaps.

The area around the carpet has patterns such as wood grain and stone grain, so it has a higher decorative effect than a simple vinyl chloride surface.For example, if it has a wood grain pattern, it can be used as a high-quality tread, no matter how damaged or cheap the underlying board is. It gives the impression that a carpet is attached, and if a pattern similar to a cushion floor is attached, it has the effect of enhancing the decorative effect according to the purpose, as if the carpet was carefully laid on top of the cushion floor.

Especially if the flooring leading to the stairs is carpet, wood cushioned flooring, or.

Even if it is a P tile, by matching the plates around the carpet to the respective patterns, it is easy to maintain the decoration with the floor surface, contributing to the overall decorative effect.

For example, if the floor has a P tile pattern, board 1 around the carpet
If you make it a P tile, it becomes a stepping board.

It also has the advantage of being able to be installed directly onto the concrete without having to take the trouble to mount P tiles in the area, saving costs and labor charges for installing P tiles.

In addition, the cross-sectional structure is gently sloped upward toward the leading edge corner, which prevents the tip of the foot from slipping at the leading edge corner, and since there are no irregularities on the surface, there is no possibility of dirt clumping. It can be kept clean and maintained.

The board itself is elastic and has a cushioning effect even if it falls.

For installation, since the sides are already inverted, there is no need for nails, metal fittings, etc. to press the front edge corner 3' of the carpet against the stairs, and there is no possibility of injury by touching the metal fittings.

When the proposed carpet is cut to size, the area is kept to a minimum to prevent it from being cut, so the carpet is installed in the central part where it is normally stepped on, as shown in Figure 3. Limited to 60-70% area.

For this reason, it is cheaper than laying the entire surface of the tread, and in terms of effect, since there is carpet on the part where the foot steps on and the corner of the front edge, the foot feels like there is carpet on the entire surface, and when going up. Since the carpet can be seen even on the front edge where it is most visible, it is inexpensive but has the same effect as having carpets all over the surface.

Claims (1)

[Scope of utility model registration request] A carpet made of natural yarn or synthetic fiber is placed on the surface of a substrate made of synthetic resin such as rubber or vinyl chloride, on which a film with an arbitrary pattern such as the grain of natural wood or the striped pattern of stone is adhered to the surface. The board is sewn or fused so that the above pattern appears on the surrounding area, and the board is sloped gently upward from one end to the part corresponding to the front edge corner of the stair tread with respect to the horizontal plane of the stair tread. This carpet for stair repair is characterized in that the inclination is sharply reduced at a point beyond the center line of the part corresponding to the edge corner, and a substantially V-shaped groove is formed on the back surface of the carpet.
