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, this type of mat has a clear boundary between the front side of the mat body and the corner padding material, and the mat body is made of fibrous material such as a carpet or rug, and the mat body is made of, for example, synthetic resin. What is the integrally molded corner guard material?
Naturally, since the materials and molding forms are different, there is a sense of discomfort in the design, and there is also a sense of discomfort in the stepping pressure due to the difference in flexibility when going up and down.

This idea was developed in consideration of the above-mentioned circumstances, and the horizontal piece of the corner guard material that comes into contact with the tread part is formed into a thinner shape from the base to the tip, and the horizontal piece of the corner guard material that comes into contact with the tread part is formed into a thinner shape from the base to the tip, and the horizontal piece is made thinner from the base to the tip. By forming the buffer zone, which is made up of a plurality of bendable pointed ridges, at almost the same height, it eliminates the sense of incongruity between the corner pad and the mat body, and also reduces the feeling of stepping on the floor due to the difference in flexibility when going up and down. It is an object of the present invention to provide a stair mat that eliminates a sense of discomfort and protects the leading corner of the stairs, which is most frequently worn.

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 B.
It is formed into a cross-sectional shape and is attached to the corner of the tip formed by the riser part B and the tread part C.

The horizontal piece 1b is formed in a thinner shape in order from the bulge 1c that bulges at the base, that is, the corner of the horizontal piece 1b and the vertical piece 1a, toward the tip, and has a longitudinally A plurality of bendable pointed protrusions 2゜2a along the
. . . are arranged in rows at equal intervals, and are integrated with the horizontal piece 1b and protrude in the vertical direction.

This buffer band 2 is formed at almost the same height in the vertical direction, and is connected to the mat main body 3 laid on the tread surface C and the corner guard material 1.
It is designed so that the top surfaces of the buffer strip 2 and the mat main body 3 are approximately at the same height when they are arranged in series.

The corner pad 1 and the mat main body 3 may be connected to each other through the thin-walled piece 1d extending from the horizontal piece of the corner pad 1 toward the tread surface, or as shown in the figure. The corner guard material 1 and the mat main body 3 may be fixed and connected to the upper surface of a thin-walled joint plate.

In the above embodiment, a buffer band 2 is formed in which the pointed protrusions 2a, 2a, . And as shown in FIG. 4, a plurality of pointed ridges 2a/, 2al, . The buffer band 2' may be formed by protruding horizontally from the horizontal piece 1b.

In the stair mat of this invention, which is constructed as described above, the horizontal pieces 1b constituting the corner pads 1 are formed in a sequentially thinner shape from the edge part 1c toward the tip, and the upper surface has a A plurality of bendable pointed ridges 2a or 2 along
Buffer belt 2 that protrudes from a/ at equal intervals from each other.
or 2', the buffer band 2 or 2' has the effect of increasing the buffering effect sequentially toward the side of the mat body 3, and the cushioning band 2 or 2' has the effect of gradually increasing the buffering effect toward the side of the mat body 3, and the cushioning band 2 or 2' has a It is possible to eliminate the uncomfortable feeling of stepping pressure caused by differences in flexibility.

In addition, since the corner protector 1 and the mat main body 3 are installed in series so that the buffer strip 2 and the top surface of the mat main body 3 are approximately at the same height, the corner protector 1 and the mat main body 3 are in harmony. It is possible to eliminate the sense of incongruity in the design, and furthermore, by forming the buffer band 2 or 2' on the corner guard material 1, it is possible to protect the corners of the stairs where the wear is most severe. Excellent effects can be obtained.

In the above embodiment, the case where the bulging part 1c of the corner guard 1 is not made hollow is explained, but if the bulging part 1c is made hollow in order to provide a cushioning effect to the riser part, In this case, the cushioning effect of the cushioning band 2 or 2' may be gradually increased toward the side of the mat body, as described above, taking into account the thickness of the tread side.

As explained above, according to this invention, it is possible to harmonize the corner guard material and the mat body and eliminate the sense of incongruity in design, and the buffer strip formed integrally with the horizontal piece can be The piece is most flexible where it is thinnest,
As the horizontal piece becomes thicker toward the base, the flexibility of the buffer band also decreases, reaching the original hardness of the corner guard material at the bulge. It is possible to eliminate the uncomfortable feeling of stepping pressure caused by the difference in the degree of flexibility of the stairs, and to protect the top corners of the stairs, which are subject to the most wear.Moreover, the corner guard material and the buffer band can be easily molded into one piece. It has excellent effects such as being able to be molded into shapes, and its utility value is remarkable.
