Description

[Detailed description of the invention] The present invention relates to a non-slip device installed on stairs, and in particular, the invention relates to a non-slip device that is attached to a stairway, and in particular, a non-slip device that connects a flat main body portion that is fixed to a stair tread and a front fixed edge that is fixed to a stair riser surface. A cushion part that covers the corner of the stairway and includes a receiving part, a flexible receiving piece that projects diagonally upward continuously from the receiving part, and a flexible bulging piece that covers this flexible receiving piece. This cushioning part provides excellent shock absorption at the most dangerous corner of the stairway, and at the same time, provides an excellent anti-slip effect at the corner of the stairway, and is also highly durable. The purpose is to provide an anti-slip material.

The structure of the present invention will be explained based on the embodiments shown in the attached drawings. The anti-slip material for stairs, denoted by the symbol A, is made entirely of an elastic material such as soft synthetic resin or rubber, and has a cross-section shaped like a cross-section. A main body part 1 in the shape of a flat plate fixed to the tread of the stairs, a front fixed edge 2 fixed to the riser surface of the stairs, and a connection between the main body part 1 and the front fixed edge 2. It is composed of a cushion part 3 that covers the corner part of the stairs.

The cushion portion 3 includes the main body portion 1 and the front fixed edge 2.
A receiving part 8 has a thickness similar to that of the stairway and has a rear surface formed in a substantially right-angled shape corresponding to the corner of the staircase. A flexible receiving piece 4 whose protruding surface is formed into a substantially arc-shaped surface extends at least from the distal end side of the main body 1 and covers the flexible receiving piece 4 at a predetermined distance d, and A flexible bulging piece 5 that protrudes upward from the upper surface of the portion 1 and also protrudes forward from the front surface of the front fixed edge 2, and has a substantially C-shaped cross section with a free end. When this cushion part 3 is deformed by tread pressure etc., the lower surface of the flexible bulging piece 5 comes into contact with the approximately arcuate protruding surface of the flexible receiving piece 4, and this flexibility The receiving piece 4 supports the flexible bulging piece 5 while being elastically deformed. In this case, the flexible receiving piece 4 deforms itself to support the elastic force to the receiving part 8, and the step It is designed to receive a buffering effect.

As described above, in this cushion portion 3, the flexible receiving piece 4 is formed to have a substantially hollow circular cross section, and the flexible bulging piece 5 is formed to have a substantially C-shaped cross section with the tip as a free end. However, as shown in FIGS. 2 through 5, various modifications are possible, and these will be explained below.

First, the anti-slip material A shown in FIG. 2 is provided with a projecting piece-shaped auxiliary receiving piece 6 below the flexible receiving piece 4, that is, on the side of the front fixed edge 2, so that the flexible bulging piece 5 deforms when stepped on. is supported by the flexible receiving piece 4 and this auxiliary receiving piece 6.

Furthermore, unlike the above-described embodiments, the anti-slip material A in FIG. Flexible receiving pieces 4 are integrally connected to the front edge of the upper end to form a hollow part.
In addition, the flexible receiving piece 4 is formed to have a substantially T-shaped cross section, and this flexible receiving piece 4
A large number of auxiliary receiving pieces 6 are protruded from the main body 1 side and the front fixed edge 2 side, and the flexible bulging piece 5 deformed when stepping is connected to the flexible receiving piece 4 and the auxiliary receiving piece from the lower surface side. It can be evenly supported by the stopper piece 6.

Furthermore, the anti-slip material A shown in FIGS. 4 and 5 has a receiving piece 4 having a bulged tip (FIG. 4) or a substantially C-shaped cross section with the tip as a free end. (Figure 5).

In each of the above-mentioned embodiments, reference numeral 7 indicates a non-slip uneven portion formed on the upper surface of the main body portion 1.

Further, in each of the above embodiments, the entire anti-slip material A is made of soft synthetic resin and has an abbreviated cross-section. However, the present invention is not limited to this. Of course, it is also possible to have a thin plate made of metal or hard synthetic resin integrally or integrally formed on the side to improve adhesion to the stairs.

The present invention has the above-mentioned configuration, and has a cushion part that connects the main body part and the front fixed edge and covers the corner of the stairs. a receiving part having a thickness of approximately 1,000 yen, and having a rear surface formed in a substantially right-angled shape corresponding to the corner of the staircase; and a receiving part that is continuous with the receiving part and protrudes obliquely upward, and the protruding surface is formed into a substantially arc-shaped surface. The formed flexible receiving piece extends from at least the distal end edge of the main body portion, maintains a predetermined gap with the flexible receiving piece, covers the flexible receiving piece, and extends above the upper surface of the main body portion. It consists of a flexible bulging piece that protrudes and projects forward from the front surface of the front fixed edge, and this flexible bulging piece that deforms when pressed is elastically supported by a receiving piece from below. So,
When an impact such as tread pressure is applied to this cushion part when going up or down, the flexible bulging piece first elastically deforms, and the lower surface side of this flexible bulging piece comes into contact with the flexible receiving piece, and this flexible bulging piece and The flexible receiving piece is elastically deformed to absorb the treading force, and the elastic deformation of the flexible receiving piece is supported by the receiving part.

Therefore, the impact force that acts on the most dangerous corner of the stairs is absorbed in stages by the flexible bulging piece, the flexible receiving piece, and the receiving part, depending on the magnitude, and the flexible bulging piece Since a gap is formed between the holder and the flexible receiving piece, it significantly reduces the cushioning caused by impact and makes the flexible bulging piece even softer against the human body. Even if a person hits a corner, large diameter holes can be prevented.

In addition, after the flexible bulging piece comes into contact with the flexible receiving piece during treading, it receives the treading pressure by the elastic action of the flexible receiving piece while supporting the elastic force of the receiving part. Moreover, since the flexible bulging piece and the flexible receiving piece are integrally formed with the receiving part, the main body part and the front fixed edge are continuous and integral, so that the load is not concentrated in one place and can be quickly transferred to the other. Since the absorption is dispersed and further extended to the main body part and the front fixed edge, the flexible bulging piece can support the pedal pressure load without completely collapsing, and this results in an excellent pedal with good cushioning properties. It provides a comfortable feel and exhibits an excellent anti-slip effect.

In addition, the flexible bulging piece that has been deformed to some extent is provided on the lower surface side with a predetermined gap, is continuous with the receiving part and protrudes obliquely upward, and has a substantially arcuate surface on its protruding surface. Because it is supported by a stopper, it immediately returns to its original shape when the impact from treading pressure is removed, and even when it is deformed, it is not pressed directly against the corner of the stairs, improving its durability. It can withstand long-term use.

Furthermore, since the rear surface of the receiving part is formed into a substantially right-angled shape, it is easy to position it at the corner of the stairs during construction.
