Description

[Detailed Description of the Invention] This invention relates to a non-slip device for buildings that is attached to the corners of stairs to prevent slipping and falling, improve safety when going up and down stairs, and protect the corners of stairs. 0, especially
This invention relates to a non-slip device for buildings, in which a mounting board made of hard synthetic resin is integrally attached to a non-slip main body made of soft synthetic resin.

Conventionally, this type of anti-slip for buildings has been made by attaching a non-slip body made of soft synthetic resin integrally or shaped to the surface of a mounting board made of hard synthetic resin and having an approximately L-shaped cross section. there were.

By the way, if the height of the anti-slip protrusion from the treads or risers of the stairs is increased, it may cause tripping and injury when going up and down the stairs, so the thickness of the anti-slip is inevitably limited.

However, in the conventional anti-slip method, which simply forms two layers of hard synthetic resin and soft synthetic resin,
Unless the anti-slip body made of soft synthetic resin is made thicker, it will not be possible to achieve the purpose of using soft synthetic resin, that is, to obtain a sufficient foothold and tread feeling. Because the protruding height from the stair treads and risers is limited within a certain range, it is not possible to increase the thickness of the anti-slip body made of soft synthetic resin. The anti-slip body partially moves up and down when weight is applied to the anti-slip body because it is integrally attached with a mounting board made of hard plastic or resin to improve the adhesion effect and rigidity. It merely exerts its elastic force in the direction, but does not provide a sufficient foothold or treading feeling.

In view of this point of view, the present invention suppresses the protruding height from the treads and risers of the stairs within a predetermined range, forms a hollow part with a small height in the step part, and also forms a hollow part with a small height dimension at the corner of the stairs. A relatively large gap is formed on the back side of the connection part that covers the
The synergistic effect of these hollow parts and void parts provides a sufficient foothold and a satisfying stepping feeling, and improves shock absorption properties at the corner of the stairs. To provide a non-slip for a building which can prevent partial peeling and floating by a mounting board made of hard synthetic resin integrally formed on the lower surface of a step part and a leading edge.

Hereinafter, the present invention will be described in detail based on an embodiment shown in the accompanying drawings.

1 and 2, a non-slip S for buildings according to an embodiment of the present invention is shown.

This non-slip S for buildings is made by attaching a non-slip main body 1 made of soft synthetic resin and a mounting board 2 made of hard synthetic resin to one piece.

The anti-slip main body 1 is attached to a base plate 2 on the tread 4 of the stairs 3.
A wide band-shaped step portion 6 is fixed to the riser surface 5 of the stairs 3 and has a plurality of anti-slip protrusions 11 formed along its longitudinal direction on its upper surface, and a mounting board 2 is attached to the riser surface 5 of the stairs 3. The front edge portion 7 is fixed to the step portion 6 and the front edge portion 7 through the
and a connection part 8 having a substantially arch-shaped cross section and formed thinner than the wall thickness of the step part 6 and the front edge T, and the step part 6 has a staircase. The hollow portion 9 has a small height h1 in the vertical direction with respect to the tread surface 4K of No. 3, and the height h1 and h2 in the vertical and horizontal directions are both the height h of the hollow portion 9 due to the connecting portion 8. The corners of the stairs 3 are covered while forming a larger gap 10, and the back side of this gap 10 is open.
The connecting portion 8 forming the tread portion 6 projects upwardly from the surface 6a of the step portion 6, and also protrudes forward from the surface [m7a] of the front edge portion 7.

Therefore, according to the anti-slip S for buildings of this embodiment, when it is attached to the corner part of the staircase 30, a pressure-sensitive adhesive sheet is attached to the mounting board 2 attached to the underside of the step part 6 and the front edge part I, respectively. By providing an adhesive layer such as, arranging and adhesively fixing the tread portion 6 at a predetermined position on the tread surface 4, and arranging and adhesively fixing the leading edge portion T at a predetermined position on the riser surface 50, it is possible to easily: Moreover, the anti-slip S can be firmly attached to the stairs 3.

In the above embodiment, only one hollow part 9 is formed in the step part 6, but a plurality of hollow parts 9 are formed in the step part 6.
Also, as the soft synthetic resin, soft vinyl chloride resin, polyethylene resin, etc. are used, and as the hard synthetic resin, polycarbonate resin, ABS resin, etc. If a synthetic resin material of the same type is used, the anti-slip main body 1 and the mounting board 2 can be integrated, and the fear of interlayer peeling can be eliminated.

As described above, the present invention forms a hollow part 9 with a small vertical height hi in the step part 6 of the anti-slip main body 1 made of soft synthetic resin, and a connecting part formed in a substantially arch shape in the cross section. Vertical and horizontal height h2h3 by section 8
cover the most dangerous corner of the staircase 30 while forming a gap 10 larger than the height h1 of the hollow section 9, and
This connecting portion 8 protrudes upward from the surface 6a of the step portion 6 and also protrudes forward from the surface 1a of the front edge portion 7.
Therefore, even if the protruding height of the treads 4 and risers 5) of the stairs 3 is suppressed within a predetermined range and the thickness of the anti-slip body 1 is thin, the hollow part 9 and the void part 10 and the fact that the anti-slip main body 1 is made of soft synthetic resin act synergistically, and the non-slip main body 1 is deformed enough to provide a sufficient foothold and a good stepping feeling.

Moreover, the gap 10 formed in the connecting portion 8Vc is
The connection portion 8 is larger than the hollow portion 9 formed in the
is easily deformed, and furthermore, the connecting portion 8 protrudes upward from the upper body 6a of the step portion 6, and the surface 7a of the front edge portion 1
This connection part 8 protrudes further forward than the stairs 3.
It closely follows the movement of a person's feet when going up and down the stairs, providing a better foothold and providing an extremely good feeling when stepping on the stairs. Even in the event of someone falling down or falling down, the connecting portion 8 that protrudes upward and forward from the corner of the stairs 3 undergoes relatively large elastic deformation and absorbs the impact, significantly reducing the risk of serious injury. Furthermore, since the connecting portion 8 in which the large gap 10 is formed can also deform in the direction of movement of the person when going up and down the stairs 3, that is, in the front and rear direction, even if the person goes up and down the stairs 3, Even if a fingertip or the like is caught, the connecting portion 8 deforms in the front-back direction where force is applied to absorb the force, and the risk of falling is significantly reduced.

In addition, the tread portion 6 is shaped to be wide and has a plurality of protrusions 11 formed along the longitudinal direction on its upper surface, which simply protects the corner of the stairway 3 and prevents the stairway 3 from forming. In addition to preventing the tread from becoming slippery, the tread portion 5K located on the tread 4 actively prevents slipping on the tread 4, thereby further improving the anti-slip effect. The tread portion 6 and the front edge portion 7 are fixed to the tread 4 and riser surface 5 of the stairs 3, respectively.
Since the tread portion 6 and the connecting portion 8, which form the hollow portion 9 and the void portion 10, are bonded to each other through the mounting board 2 made of hard plastic or resin, which is integrally formed with the tread plate 2, these Hollow part 9
Even if a portion is largely deformed due to the gap 10 or the gap 10, the tensile force caused by this partial deformation is dispersed throughout the non-slip S by the mounting board 2, and the mounting board 2
It does not act on the adhesive surface between the and the stairs 3, and the strong adhesiveness of the anti-slip S is ensured.
