Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a non-slip for carpeted stairs which has been improved to be suitable for stairs covered with carpets, carpets, etc.

Conventionally, anti-slip products for stairs are installed at the tip of stairs covered with carpet.
Those that have a metal frame fitted with a filler, or those that have a semicircular hollow bulge-shaped cushion integrally formed at the tip corner of a flat plate-like main body made of a soft synthetic resin material are used. However, the former fitting type non-slip has the disadvantage that the frame ends for forming the engagement portions of the filler at the front and rear ends are exposed on the top surface side, causing a feeling of discomfort with the carpet. In addition, since most of the latter integrated non-slip body is made of fleshy parts of the flat plate-like main body, there is a relatively large difference in flexibility from the carpet, while the corner cushions are slightly slanted. Since it protrudes upward, it has the disadvantage of being easily deformed and cracked.

This invention was made in view of the above-mentioned drawbacks of conventional anti-slip devices, and it protects the leading edge of stairs, prevents permanent deformation and cracks caused by loads and impacts on the leading edge, and also protects the leading edge of stairs from being permanently deformed or cracked. To provide a non-slip for stairs with a carpet floor, which has similar flexibility and has a good cushioning effect, and can be used for a long period of time without giving people a feeling of discomfort between the non-slip carpet and the carpet. It is something to do.

Hereinafter, preferred specific examples of the anti-slip for carpeted stairs according to the present invention will be described with reference to the drawings.
