Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a non-slip device for a building, and particularly to a non-slip device suitable for a staircase such as a steel-framed staircase where the nosing portion has an arcuate shape with a relatively large radius of curvature.

To explain the configuration of the present invention with reference to an embodiment shown in the accompanying drawings, an elastic cushion body C made of a flexible material such as soft vinyl chloride and having a substantially flat shape as a whole is attached to a staircase 11.
has a wide and elongated hollow part 6 whose starting end is located above the tip of the tread 14 and whose terminal end is located in front of the upper end of the substantially vertical riser 13 of the staircase 11, and It is composed of a hollow buffer piece 15 that is bent and fixed along the shape of the nose 12 of the staircase 11 or from the nose 12 of the staircase 11 to the riser 13. 11, a protrusion 16 is formed that protrudes to at least the same height as the upper surface of the anti-slip main body 1 and serves as a foothold when in use, whereby the hollow part 6 has a hollow bulge. 4 is formed on the top surface of the anti-slip main body 1, and a large number of uneven portions 2 for anti-slip purposes are also formed on the upper surface of the anti-slip main body 1.

Further, reference numeral 7 in the figure is a thin plate provided on the lower surface of the elastic cushion body C, that is, the lower surface of the anti-slip main body 1 and the thin film 5. Although it is easy to bend or deform into a curved shape, it is It exhibits rigidity against force, and is made of a metal plate such as aluminum or stainless steel, or a hard resin plate such as hard vinyl chloride resin, ABS resin, or polycarbonate. They are provided so that they can be integrally joined together when the anti-slip main body 1 is molded using a stop protrusion, a bent strip 8, etc., or they can be applied with an adhesive and pressed together at the time of molding or immediately after.

Reference numeral 9 denotes a pressure-sensitive adhesive sheet provided on the lower surface of the thin plate 7, and is protected by a release paper 10. During use, this release paper 1
Peel off the 0 and glue it to the stairs 11.

The adhesive sheet 9 is a slightly thick sponge-like material made of foam or the like so that it can absorb the uneven pattern of the stairs 11.
(Fig. 4) may be used.

In order to install the non-slip building material of this embodiment on the stairs 11, as shown in FIG.
is located approximately in the center of the nosing 12, and at least the hollow buffer piece 15
The hollow part 6 of the stair nosing 12 is installed so as to cover the entire surface of the stair nosing 12, and then the non-slip main body 1 is fixed and attached to the tread 14 of the stairs 11, or the non-slip main body 1 is first positioned and fixed on the tread 14. Then, the hollow buffer piece 15 is bent to match the shape of the nosing 12 and fixed to attach it.

The present invention has the above-described configuration, and includes a wide hollow buffer piece 15 integrally formed along the longitudinal direction of the tip edge of the anti-slip main body 1 fixed to the tread surface 14 of the stairs 11. The hollow portion 6 of the hollow buffer piece 15 is formed in a wide and elongated shape such that at least its starting end is located above the tip of the tread 14 and its terminal end is located in front of the upper end of the riser 13. The epithelial part 3 on the upper surface side of the cavity 6 and the thin film 5 on the lower surface side are extremely easy to bend or deform into a curved shape, and the shape of the step nosing 12 may change, for example, the radius of curvature of the arcuate surface becomes large or small, or Even if the angle changes in size around a right angle, the hollow buffer piece 15 can be easily bent or deformed accordingly, making the installation work extremely easy, and the hollow buffer piece 15 can be easily bent or deformed accordingly. Due to its elasticity, the force of rebound is small, and furthermore, the partial deformation of the epithelial portion 3 during treading can be dispersed over a wide range.

In addition, the hollow buffer piece 15 has its epithelial portion 3 formed at approximately the same height as the upper surface of the anti-slip main body 1;
This epithelial part 3 is formed with a protruding part 16 that protrudes to at least a height approximately equal to the top surface of the anti-slip main body 1 when attached along the nosing 12 of the staircase 11, and serves as a foothold during use. A hollow bulge 4 is formed in the cavity 6 by the protrusion 16.
is formed, so when going up and down the stairs 11, this protrusion 1
6 serves as a foothold that deforms following the movement of the sole of the foot, which significantly improves the feeling of stepping on it, and also significantly improves the anti-slip effect of the step nosing 12. This significantly improves the impact buffering effect of the step nosing 12, and even in the event of an accidental fall, it is possible to significantly reduce bruises caused by the step nosing 12.

Further, since a thin plate 7 that can be bent or deformed into a curved shape and exhibits rigidity against tensile force is integrally provided on the lower surface of the elastic cushion body C, adhesiveness to the stairs 11 is improved. This is a significant improvement, and even if the elastic cushion body C is partially deformed, the tension caused by this deformation will not extend to the adhesive surface between the thin plate 7 and the stairs 11, and the edges will not peel off. There is no possibility of partial lifting, and a stable mounting state can be maintained for a long period of time.

Furthermore, since the elastic cushion body C is entirely made of a flexible material, the elastic cushion body C is manufactured into a molded length within the elastic deformation region of the thin plate 6 integrally provided on the lower surface of the elastic cushion body C. It can be rolled up to simplify handling such as storage and transportation, and it can be cut into predetermined dimensions one after another on site, almost eliminating product loss.

Moreover, for this reason, it can be easily installed by amateurs not only for use at large construction sites such as medium-to-high-rise buildings, but also for existing stairs in ordinary homes.

The embodiment shown in Figure 3 is different from the above embodiment,
The epithelial part 3 and the anti-slip uneven part 2 are made of a wear-resistant material such as urethane or nylon to reduce wear, and the epithelial part 3 has a hardness in the bendable range of semi-hard. is formed.

In addition, in the same embodiment shown in Figure 3, in order to make it easier to bend, a large amount of plasticizer is used to make it flexible, and silicon carbide etc. are mixed in to improve wear resistance. You can try it.

Although the case where the hollow buffer piece 15 is used after being bent has been described above, it is also possible to use the hollow buffer piece 15 as it is as a whole without bending it.
