Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a non-slip device for stairs that is used by being fixed to the nosing of a staircase to prevent accidents such as falling down stairs, and in particular, it relates to a non-slip device for stairs that is used by being fixed to the nosing of a staircase to prevent accidents such as slipping down stairs. This invention relates to a non-slip device for stairs that can be attached to stairs covered with rugs.

[Conventional technology and problems]

BACKGROUND ART Recently, mats such as mats are often placed on the treads or risers of stairs in order to improve the heat retention or sound absorption performance of the stairs and to give them a more luxurious appearance.

In this way, when attaching a non-slip to a staircase with a rug installed, if the non-slip is fixed directly onto the rug, the non-slip will wobble or come off easily. After peeling off the stairway to expose the stairway surface, the anti-slip material is fixed to the stairway surface, which poses a problem in that it takes time and effort to install.

The present invention has been made in response to these circumstances, and an object of the present invention is to provide a non-slip for stairs that can be directly adhered to the upper surface of a rug laid on stairs.

[Means for solving problems]

FIG. 1 shows a non-slip for stairs according to the present invention, which is constructed by covering the upper surface of a hard base material 1 with a non-slip material 2 made of a soft material.

The hard base material 1 has a flat plate part 3 corresponding to the tread part B of the stairs A, and a hanging part 4 corresponding to the riser part C of the stairs A, and is formed into a substantially L-shaped cross section.
On the back side is a rug D to be laid on the tread B of the stairs A.
A plurality of protrusions 5 whose tips come into contact with the base D' are protrudingly provided.

[Effect]

Usually, the rug D laid on the stairs A is formed by applying pile processing etc. on the relatively tightly woven base D', or by applying flocking etc. on the base D', and the surface part is is flexible, but the base
It has a constant hardness at D'.

The present invention has been made focusing on this point,
A protrusion 5 protruding from the back surface of the flat plate portion 3 of the hard base material 1
When it is installed, it penetrates the flexible part D'' of the rug D and comes into contact with the hard base D', and the anti-slip is in the same state as if it were installed directly on the tread part B of the stairs A.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the embodiment of the anti-slip for stairs of the present invention shown in FIG. 1, the anti-slip material 2 is detachably attached to the hard base material 1.

That is, a front engagement recess 6 is formed in front of the hanging part 4 of the hard base material 1 formed by molding a hard synthetic resin, and a front engagement recess 6 is formed from the rear edge of the flat plate part 3 toward the front upper part. A rear engagement recess 6' is formed,
By locking the locking protrusions 8, 8' of the hard auxiliary material 7 integrally formed on the back surface of the anti-slip material 2 into the front engagement recess 6 and the rear engagement recess 6', the anti-slip material 2 2 is attached to cover the hard material 1.

Therefore, in this embodiment, after the locking protrusion 8' on the rear end side of the auxiliary member 7 is brought into contact with the rear engaging recess 6', this locking protrusion 8' is brought into contact with the rear engaging recess 6'. 6', the anti-slip member 2 is rotated downward, and the locking portion 8a of the locking protrusion 8 on the tip side of the auxiliary member 7 and the locking portion 6a of the front engagement recess 6 are moved. By interlocking them, the anti-slip material 2 can be mounted and supported on the hard base material 1.

The anti-slip material 2 is made of soft vinyl chloride resin, and an appropriate number of voids 9 are formed at the interface with the auxiliary material 7 and at the center of the tip in order to improve its flexibility. On its upper surface, a plurality of anti-slip grooves 10 are formed for the purpose of improving the anti-slip effect.

In addition, in this embodiment, the anti-slip material 2
A case is shown in which the auxiliary material 7 is integrally fixed to the back surface of the non-slip material 2 and the hard base material 1 is made removable, but it is not necessarily necessary to make the auxiliary material 7 removable. Alternatively, the anti-slip material 2 may be formed directly on the hard base material 1 by integral molding, or it may be fixed by adhesive, or even if it is removable, various forms can be taken. Of course, it is also possible to use a thin plate of a metal material such as aluminum as the auxiliary material 7, as shown in FIG.

Furthermore, in the embodiment shown in FIGS. 1 and 2, a curved surface 11 is formed at the portion where the flat plate portion 3 and the hanging portion 4 meet.

This curved surface 11 is particularly effective when the rug D is also laid on the riser C of the stairs A, and the tip of the flexible portion D'' of the rug D at the abutting corner is arranged by this curved surface 11. As a result of being arranged in an arc shape, the reaction force applied to the back surface of the hard base material 1 is distributed approximately evenly, and wobbling of the hard base material 1 can be effectively prevented.

〔Effect of the invention〕

As is clear from the above description, according to the anti-slip for stairs according to the present invention, a protrusion is provided on the back surface of the flat plate portion of the hard base material, the tip of which comes into contact with the base of the rug laid on the tread of the stairs. Therefore, when the protrusion is installed, the protrusion penetrates the flexible part of the rug and abuts on the hard base, and the anti-slip is in the same state as if it were installed directly on the tread of the stairs. Therefore, even if the stairs are covered with a rug, it can be installed reliably without wobbling, and the man-hours required for removing the rug can be saved.
