Description

[Detailed description of the invention] This invention relates to a non-slip staircase for stairs that is improved to be suitable for stairs covered with carpets, felt, mats, etc.

Traditionally, when a rug is placed on a staircase, the rug is usually pasted on the staircase or
It has been fixed to the stairs using a carpet presser.

However, with this type of carpet laying method, the carpet is extremely worn out at the leading edges of the stairs, causing confusion and making long-term use difficult.

In addition, conventionally, anti-slip devices for this kind of carpet have been attached to the top of the carpet at the leading edge of the staircase to prevent partial wear of the carpet. It is difficult to fix the anti-slip.

This is because the metal carpet holder for this kind of carpet is driven into the staircase by piercing the non-slip carpet or through the carpet through the non-slip hole, and attaching the non-slip to the edge of the staircase. Because it is fixed, it is difficult to attach the anti-slip to the stairs.

The purpose of this invention is to protect the leading edge of each stair step, and to provide a non-slip and cushioning effect to the leading edge of each stair step. Easy to install on stair steps, protects from
Furthermore, in the case of stairs where carpets, felts, mats, etc. are laid down, the work of laying the mats is simple and easy, and it can be fixed firmly to the steps of the stairs. It eliminates local wear of the rug at the edges, allows the rug to be used for a long time without giving people a feeling of discomfort due to such wear of the rug, and further allows the rug to be firmly assembled, and , a rug that allows the rug to be easily removed, allows the rug to be replaced depending on the degree of wear and tear on the rug, and allows it to be washed and reused depending on soiling; Our goal is to provide anti-slip products for stairs that are lined with felt, mats, etc.

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

Figures 1 to 3 show a specific example 10 of the anti-slip for stairs of this invention, which is applied to spread a carpet 30 consisting of a plurality of carpet pieces 31 on steps 101 of a staircase 100 of a building.

The anti-slip 10 for stairs is located at the tip edge 104 of the step 101.
The edge base 11 made of hard synthetic resin is attached to the tread surface 102 of the step 101 so as to cover the step 1, and the step 1
At the front end side, a soft synthetic resin edge bead cushion 12 integrally molded on the edge base 11 and the rear of the edge bead cushion 12 are located at the leading edge 104 of the 01. That is, on the rear end side, a flanged groove 13 formed on the upper surface of the edge base 11 and a flanged groove 13 formed on the upper surface of the edge base 11.

A flexible riser cover flap 16 integrally molded into the edge bead cushion 12, as well as a flexible tread cover flap 15 integrally molded into the bead cushion 12. It is composed of.

The edge base 11 has a positioning lip 17 integrally molded at the tip so as to cover the tip edge 104 of the step 101 and hooked onto the riser surface 103 of the step 101, and prevents the slip 10 from sliding onto the step 101. Makes installation easy.

The edge bead cushion 12 is integrally molded on the edge base 11 from a soft synthetic resin, and is particularly formed of an elastic tube located at the front end of the edge base 11 and provided with a hollow portion 18. structure, which further improves the cushioning effect.

Further, the edge bead cushion 12 is provided with tread side and riser side abutment surfaces 19 and 20 for abutment with the leading edge and rear edge of the carpet piece 31. The surface 19 is inclined.

Moreover, it is of course possible that the riser side abutting surface 20 is formed into an inclined surface similarly to the tread side abutting surface 19.

Furthermore, the edge bead cushion 12 has a non-slip surface 21 having a serrated cross section from the top surface to the front surface, thereby improving the anti-slip effect.
