Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a stair anti-slip device that is used by fixing it to the treads of wooden stairs in general households, and is particularly concerned with highly safe stair anti-slip devices. be.

[Conventional technology]

BACKGROUND ART Recently, in order to prevent unexpected accidents caused by falling down stairs at home, a stair cleat having an anti-slip effect has been installed at the tip of the tread of the stair.

Normally, when installing a stair anti-slip on a staircase in a home, it is fixed directly to the stair tread A, as shown in Figure 3, and the stair anti-slip is attached to the surface of the tread A. It has become a state of prominence.

On the other hand, in this case, if the protruding dimension H of the non-slip stair tread from the surface of the tread A is too large, there is a risk of tripping on the non-slip.
It is formed by reducing its thickness dimension.

[Problem that the invention attempts to solve]

However, although the anti-slip effect can be expected in products with a thin overall thickness like this,
On the other hand, it cannot be expected to be effective as a cushion at all, and there is a problem in that it lacks safety in case someone accidentally slips down the stairs.

The present invention was developed in response to these circumstances, and aims to improve safety by reducing the protrusion of the stair tread A from the surface and also by providing the necessary cushioning effect. The purpose is to provide anti-slip for stairs.

[Means to solve the problem]

In FIG. 1, a non-slip for stairs according to the present invention is shown, and is constructed by mounting a non-slip material 2 made of a soft material on a hard base material 1.

A hard base material 1 is housed and fixed in an installation recess B formed in a notch at the tip of a stair tread A, and has a rising edge 3 that comes into contact with a rising wall surface B' of the installation recess B, and a rising edge 3 that comes into contact with a rising wall surface B' of the installation recess B. It has a flat portion 4 that comes into contact with the bottom wall surface B'' and is formed into a substantially L-shaped cross section.

The anti-slip material 2 is formed by molding a soft material into a substantially rectangular cross section, and is mounted on the hard base material 1 by being joined at the rising edge 3 and the plane portion 4 of the hard base material 1.

This anti-slip material 2 has tongue pieces 5, 5' protruding from the front end of the tongue surface and the rear end of the upper surface, and when the non-slip material for stairs is attached to the tread A of the stairs, The tip of the tongue 5 is attached to the riser side surface A' of the stair tread A, and the tip of the rear tongue 5' is attached to the tread side surface of the stair tread A.
A'' are formed to press against each other.

[Effect]

The anti-slip material 2 in the anti-slip material for stairs of the present invention exhibits the required anti-slip effect due to its flexibility, and also has a cushioning effect due to its elastic flexure, so that it can be prevented from accidentally slipping down the stairs. The hard base material 1 is provided to securely fix the anti-slip material 2 to the tread A of the stairs.

That is, in the present invention, the anti-slip material for stairs is housed and fixed in the installation recess B cut out at the tip of the tread A of the stairs, and the amount of deflection deformation of the anti-slip material 2 is increased to create a cushion. In addition to achieving the desired effect, the protruding dimension of the non-slip stairway from the tread A is minimized, and the tip of the rear tongue piece 5' is connected to the surface of the tread A on the tread side.
The safety is improved by press-contacting the surface portion A'' and preventing the occurrence of a level difference with the surface portion A''.

〔Example〕

In the embodiment of the anti-slip for stairs of the present invention shown in FIG. 1, the hard base material 1 is formed by bending a relatively thin metal material such as a stainless steel plate material or an aluminum material into a substantially L-shaped cross section. , its rising edge 3 and flat portion 4 are fixed to the rising wall surface B' and bottom wall surface B'' of the installation recess B by appropriate means such as adhesive.

In addition, the anti-slip material 2 according to this embodiment is made by integrally molding a soft vinyl chloride resin with the above-mentioned hard base material 1, and in order to improve its flexibility,
A gap 6 is formed inside, and a plurality of anti-slip grooves 7 are provided on the upper surface of the gap 6 for the purpose of improving the anti-slip effect.

At this time, in order to improve the bonding strength between the hard base material 1 and the anti-slip material 2, a hole is provided in the rising edge 3 or flat part 4 of the hard base material 1 for pouring the resin material of the anti-slip material 2. Alternatively, the hard base material 1 and the anti-slip material 2 may be formed separately and joined with adhesive tape or the like so that the anti-slip material 2 is removable.

Furthermore, the front tongue piece 5 and the rear tongue piece 5' are
In the embodiment shown in FIG. 1, it is formed into a hook shape, but the shape can be changed as appropriate.

FIG. 2 shows another mode of use of the present invention, in which a soft anti-slip material 2 is attached to a hard base material 1' having a substantially U-shaped cross section, which is attached to a recess 8 formed in a stair tread A. This figure shows a case in which an integrally connected product is installed side by side with the anti-slip for stairs according to the present invention.

[Effect of idea]

As is clear from the above explanation, according to the non-slip for stairs according to the present invention, the anti-slip for stairs is housed and fixed in the installation recess formed in the tip of the tread of the stairs, so that the anti-slip material It is possible to increase the thickness of the non-slip stairway while minimizing the protrusion dimension from the tread.

Therefore, the amount of flexural deformation of the anti-slip material can be increased, the cushioning effect can be exhibited, and the safety can be improved.

Furthermore, a rear tongue piece is provided that protrudes rearward from the rear end of the top surface of the anti-slip material, the tip of which presses against the stair tread, so there is no step difference at the boundary between the stair tread surface and the non-slip material. This will not occur and safety can be further improved.

Furthermore, since the hard base material is formed to have a substantially L-shaped cross section, it is possible to manufacture the hard base material by a simple processing method such as bending a metal plate material, for example.

Therefore, there is no need to use troublesome methods such as extrusion processing when manufacturing the hard base material, and the manufacturing process becomes simple, so that costs can be reduced.
