Description

[Detailed description of the invention] [Industrial technical field] The present invention relates to a non-slip for stairs that is used by being fixed to the nosing of stairs to prevent slipping down the stairs, and in particular to a non-slip for stairs that is fixed to the nosing of the stairs to prevent slipping down the stairs. The present invention relates to an improvement in a non-slip for stairs, in which a non-slip material is removably mounted on a hard base material.

[Conventional technology]

In general, there are two types of non-slip stairways: one is a stair anti-slip that is formed integrally in advance, and the non-slip stair itself is directly adhesively fixed to the stairs using adhesive tape, and the other is a base material that is fixed to the stairs. Some types have anti-slip material removably attached to the top so that the anti-slip material can be replaced even if it wears out. Mortar stairs or concrete stairs can be used for various fixing methods such as being embedded in the stairs or fixed to the stairs using anchor bolts. It is widely used to prevent slipping on various types of stairs.

As shown in FIG. 2, the anti-slip material is attached to the base material by an engaging tongue protruding from the hanging part 3 corresponding to the riser part 2 of the staircase A of the base material 1. Engagement recess 5 formed by piece 4
A non-slip material 8 made of a soft material is placed in the engagement recess 5' formed at the rear end of the horizontal part 7 corresponding to the tread part 6.
It has been proposed that the device be removably fitted and installed.

[Problem that the invention attempts to solve]

However, such a non-slip material for stairs has the disadvantage that since the non-slip material 8 is made of a soft material, it deforms due to tread pressure and the non-slip material 8 is likely to fall off.

[Means for solving problems]

The present invention solves the above problem by using a base material that is fixed to the abutting corner between the riser and the tread of the stairs and has an engagement recess formed by protruding an engagement tongue from the hanging part. In the anti-slip for stairs in which the anti-slip material is removably fitted, the anti-slip material is formed by integrally bonding a soft material to the upper surface of the hard support material, and the hard support material includes: It has an engagement claw that engages with an engagement edge formed by bending the upper end of the engagement tongue of the base material inward, and a support piece that supports the upper end of the engagement tongue from the outside. This problem was solved by providing a non-slip stairway with an engaging part formed thereon.

[Effect]

That is, in the present invention, the above-mentioned anti-slip material is formed by integrally joining a hard support material and a soft material, and the engagement edge of the engagement tongue formed on the base material and the hard support material are formed. The engaging portion of the hard support material is connected to the engaging portion in such a manner that the engaging tongue is surrounded, thereby completely preventing the anti-slip material from falling off.

〔Example〕

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

Figure 1 is a sectional view showing the state in which the anti-slip for stairs according to the present invention is fixed to a staircase A made of concrete or mortar. An anchor bolt (not shown) embedded in the tread part 6 of the staircase A is shown.
etc., and is fixed to the staircase A.

This base material 1 is for fixing and holding an anti-slip material 8, which will be described later, on the stairs A, and extends outward from the lower end of the hanging part 3 corresponding to the riser part 2 of the stairs A. At the same time, the tread portion 6 is bent and formed.
The engagement recess 5' is formed by bending the rear end of the horizontal part 7 corresponding to the horizontal part 7 to form a substantially inverted L-shaped cross section, and the upper end of the engagement tongue 4 is bent inward. Engagement edge 9
is formed.

Anti-slip material 8 attached to the top surface of this base material 1
is formed by integrally molding a soft material 11 such as a soft synthetic resin on the upper surface of a hard support material 10, or by bonding it with an adhesive or the like, and the rear edge of the portion corresponding to the horizontal portion 7 of the base material 1. At the same time, the hard support material 10 is exposed to form an exposed edge 12, and the hard support material 10 and the soft material 11 are
A gap 13 is formed at the bonding interface with the cylindrical member, and the cross section is approximately L-shaped.

The hard support material 10 is for firmly fixing the anti-slip material 8 to the base material 1 by controlling the deformation of the soft material 11 due to tread pressure, and is made of an elastic hard material such as hard synthetic resin. Horizontal part 7 of base material 1
A concave portion 15 that fits into the convex portion 14 protruding from the base material 1 is formed approximately at the center of a portion corresponding to the base material 1, and a concave portion 15 that fits into the convex portion 14 protruding from the base material 1 is formed at a portion corresponding to the hanging portion 3 of the base material 1. An engagement claw 16 that engages with the engagement edge 9 and a support piece 1 that supports the upper end of the engagement tongue piece 4 of the base material 1 from the outside.
7, and an engaging portion 18 having a shape of 7 is formed.

In order to fix the anti-slip material of the present invention constructed in this way to the stairs A, first fix the base material 1 to the stairs A with anchor bolts etc., and then attach the exposed edge 12 of the anti-slip material 8 to the base material 1. When the anti-slip member 8 is rotated downward about this abutting portion, the exposed edge 12 fits into the engaging recess 5′ and slides. The stopper 8 rotates downward, and the engagement claw 16 of the engagement portion 18 formed on the hard support member 10 engages the engagement edge 9 of the base material 1.
The anti-slip material 8 is elastically engaged with the base material 1, and the anti-slip material 8 is fixed on the base material 1.

At this time, since the protrusion 14 of the base material 1 and the recess 15 of the hard support material 10 are engaged with each other, forward movement of the anti-slip material 8 is prevented, and the engagement of the base material 1 is also prevented. The engagement claws 16 of the hard support material 10 engage with the engagement edges 9 of the tongue pieces 4, and the support pieces 17 support the engagement tongue pieces 4 of the base material 1 from the outside to engage these engagement claws. 16 and the supporting piece 17 are positioned so as to surround the engaging tongue piece 4, so that the anti-slip member 8 is reliably fixed onto the base member 1.

At this time, as shown in FIG.
By forming a to be in contact with the upper end surface 9a of this engagement edge 9, the anti-slip material 8 due to tread pressure is formed.
It is possible to completely prevent the downward movement of In addition, as shown in FIG. 1, the gap 13 at the part corresponding to the abutting part between the riser 2 and the tread part 6 of the stairs A is made relatively large, so that the anti-slip material 8
The cushioning effect of the stairs A is increased, thereby preventing an accident caused by accidentally stepping off the stairs A, improving the feeling of stepping on the stairs, and improving the anti-slip effect.

[Effect of idea]

As is clear from the above description, according to the non-slip tier according to the present invention, the anti-slip material mounted on the base material is formed by integrally joining the hard support material and the soft material, and Since the engaging portion of the hard support material is engaged with the engaging tongue of the base material in a state that it surrounds the engaging tongue, the mutual connection is reliable and the anti-slip material can easily fall off. It can be used for a long period of time.
