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 up of fleshy parts, there is a relatively large difference in flexibility from the carpet, and the feet that form the hollow part are Since it protrudes slightly upward, it has the disadvantage of being susceptible to deformation and cracking.

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. It has a similar flexibility and provides a good cushioning effect, so it does not make people feel uncomfortable with the non-slip carpet, and also prevents the edges of the carpet installed on stairs from peeling off. To provide an anti-slip for carpeted stairs that can be used for a long period of time.

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