Description

[Detailed description of the invention] This invention is for stairs, which consists of a corner guard that is attached to the tip corner between the riser and the tread, and a mat body that is laid on the tread. This relates to the improvement of mats.

Conventionally, carpets such as jutan have been placed on the treads and risers of stairs to improve the stair's design effect and trample, while also muffling the sound of footsteps when going up and down the stairs, or to prevent people from taking a step off the stairs and falling. Many devices were used to reduce the impact of the shock (Utility Model Application Publication No. 47-35331).

However, such items generally have little anti-slip effect, and the load frequency and intensity of tread pressure at the tip corner formed by the riser and tread of the stairs are greater than at other parts. Due to this, only the tip corner part tends to flake off,
It has the disadvantage that it loses its appearance after long-term use.

Under these circumstances, a corner guard material made of a material with excellent wear resistance and having an uneven top surface to impart a sliding effect was attached to the corner of the tip of the staircase. ,
A device has been proposed which solves the above-mentioned drawbacks (Utility Model Application Publication No. 157718/1983).
.

However, even with such a rug, there is a clear separation between the front edge of the rug and the corner padding material, which creates a sense of incongruity in design. Because the material and hardness of the corner guard material are naturally different from those made of
This type of stair mat, which is originally installed for the purpose of improving the design effect and the comfort of stepping, has a fatal drawback.

The present invention was developed in order to deal with this situation, and it forms a buffer zone made of a group of nap-like fibers similar to that of a rug on the corner guard material, and connects the edges of the rug and the corner guard material. This design neutralizes the sense of discomfort in the design, and furthermore, by making the edge part hollow to give it flexibility similar to that of a rug, and by neutralizing the change in tread when transitioning from the rug to the edge part with a buffer band. An object of the present invention is to provide a stair mat that eliminates the discomfort of the design and the feeling of stepping on the stairs.

Examples of this invention will be described below based on the drawings.

Figure 1 shows the first embodiment of this invention.
is a corner guard, and consists of a vertical piece 1a that comes into contact with the riser B of the stairs A, and a horizontal piece 1b that comes into contact with the tread part C.
It is formed in a shaped cross section and is attached to the corner of the tip formed by the riser part B and the tread part C, and a hollow edge part 1C bulges at the corner part. Moreover, a buffer body 2 made of a group of nap-like fibers similar to the mat body 3 described later is formed on the horizontal piece lb.

Then, the corner guard material 1 formed in this way and the tread portion C
The mat body 3 laid on the horizontal piece 1 of the corner guard material 1
Thin-walled attachments extending from b toward the tread portion are connected via piece 1d.

In this case, the buffer 2 may be in the form of a lawn planted over the entire surface of the horizontal piece 1b, as shown in FIGS. 1 and 2, or in the longitudinal direction, as shown in FIG. They may be formed in multiple rows along the same line, or may be arranged in a grid pattern as shown in FIG.

Moreover, a pattern may be applied to the surface of the horizontal piece 1b as appropriate.

On the other hand, the buffer band 2 may be formed integrally with the corner guard material 1, or, as shown in FIG. You can do it like this.

Note that the edge portion 1c does not necessarily have to be completely tube-shaped, and may have an open end as shown in FIG. It may be something that you have.

Note that the connection between the corner guard material 1 and the mat main body 3 may be made by attaching the corner guard material 1 through the piece 1d (see FIG. 8), as described above. It is also possible to use a thin joint plate 4 as shown in FIG. 9 to connect the corner pads 1 and the mat main body 3 by fixing them to the upper surface of the joint plate 4, respectively.

The stair mat of this invention constructed as described above can harmonize the boundary between the front surface of the mat main body 3, that is, the end face around the tip corner, and the corner guard material 1, so that it can be used with mats made of different materials and molded forms. By making the main body 3 and the corner guard material 1 compatible, it is possible to eliminate a sense of discomfort in terms of design, and also to eliminate a sense of discomfort due to differences in flexibility when going up and down.

In addition, according to this invention, since the corner guard material 1 is provided with the buffer band 2, an excellent effect can be obtained in that the corners of the stairs, which are subject to the most wear, can be protected, and its utility value is remarkable. be.
