Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a non-slip device for stairs.

[Conventional technology]

Conventionally, as shown in Japanese Utility Model Application Publication No. 51-76119, anti-slip devices for stairs have conventionally used a metal pedestal fixed to the nosing of the stairs and a fitting groove formed on the upper surface of the metal pedestal. A soft non-slip material that was fitted and held in place was used.

[Problem to be solved by the invention]

However, in the above conventional example, unless the fitting groove is made deep, the anti-slip material cannot be held securely, so the thickness of the anti-slip material becomes thicker and a step is created between it and the tread surface, causing a problem on the stairs. This had the disadvantage that it caused stumbling when going up and down. The present invention has been made in order to eliminate the above-mentioned drawbacks, and provides a non-slip for stairs that can reduce the protrusion height from the tread as much as possible and has high installation strength at the stair nosing. The purpose is to provide.

[Means to solve the problem]

According to the present invention, the above object, as shown in FIG. 1 corresponding to the embodiment, includes: a hard substrate with fastener insertion holes bored at both ends; a non-slip material made of synthetic resin or synthetic rubber; The anti-slip material is integrally molded on the entire upper surface of the hard board except for both ends, and the hard board is fixed to the stair nosing by a fastener inserted through the fastener insertion hole. To provide a non-slip for stairs, which is fixed to the hard board, and has a car attached to both ends of the hard substrate, the back surface of which is provided with a groove capable of accommodating the head of the fastener. This is achieved by

[Effect]

In the present invention, the anti-slip member is formed by integrally molding an anti-slip material onto the upper surface of a hard substrate by press molding. As a result, the depth for fitting is not required, and the height dimension can be made lower than in the conventional example in which the anti-slip material is held by mechanical fitting. In addition, as the thickness of the anti-slip material becomes thinner, its rigidity decreases, and in order to prevent it from becoming easily peeled off from the stairs due to flexure caused by long-term use, the hard substrate is attached to the nosing of the stairs at both ends. It is fixed.

【Example】

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The hard substrate 1 of the non-slip staircase A in the embodiment shown in FIG. It has a horizontal part 10 with a fastener insertion hole 11 and a vertical part 12 corresponding to the riser surface 32 of the stairs 3, and the boundary between the horizontal part 10 and the vertical part 12 has:
A bulging strip 13 is formed for the purpose of preventing the non-slip material 2, which will be described later, from falling off and protecting its front edge. On the other hand, the anti-slip material 2 is made of synthetic resin or synthetic rubber, and covers the entire upper surface of the horizontal portion 10 of the hard substrate 1 except for the rectangular portion in plan view including the position where the fastener insertion hole 11 is formed. , is formed integrally with the hard substrate 1 by press molding or the like, with its front edge in contact with the bulging strip 13. Note that it is desirable to form an uneven portion 21 on the upper surface of this anti-slip material 2 in order to improve the anti-slip effect, but in this embodiment, the convex portion of the uneven portion 21 is discontinuous in the vertical and horizontal directions. , it is designed to have a high anti-slip effect in both directions. In addition, in order to form parts that are not covered with the anti-slip material 2 at both ends of the hard substrate 1, the anti-slip material 2 whose longitudinal dimension is shorter than the hard substrate 1 is integrally molded in advance at a predetermined position. Alternatively, the anti-slip material 2 may be formed on the entire surface of the horizontal portion 10 of the hard substrate 1, and then the anti-slip material 2 at the relevant portion may be peeled off by mechanical means or the like. In order to install the stair anti-slip A configured in this way on the stairs 3, first, the vertical part 12 of the stair anti-slip A is brought into contact with the riser surface 32 of the stairs 3, and the horizontal part 10 is moved against the tread surface 31. and fixed by the fastener 5 inserted through the fastener insertion hole 11.
In this case, it is also possible to use an adhesive, and if the stairs 3 are made of concrete, etc., as shown in FIG. 1 and FIG. Alternatively, a plug hardware 6 having a threaded portion 61 carved on the inner circumference may be driven into the tread 31 of the stairs 3, and the fastener 5 may be screwed into the plug hardware 6. In this embodiment, the upper part of the fastener insertion hole 11 is countersunk so that the head 51 of the fastener 5 does not protrude from the surface of the horizontal portion 10. As described above, attach the anti-slip A for stairs to the stairs 3.
After the cover 4 is fixed to both ends of the hard substrate 1 using, for example, an adhesive, the installation of the anti-slip staircase A is completed (see FIG. 2). As shown in FIG. 1, this cover 4 is preformed into a shape (rectangular in this embodiment) congruent with the exposed portions at both ends of the hard substrate 1, that is, the portions not covered with the anti-slip material 2. In this embodiment, a concave groove 41 having a width slightly larger than the diameter of the head 51 of the fastener 5 is formed on the back surface, and the head 51 of the fastener 5 is hard. This is provided in case it protrudes from the surface of the substrate 1. In addition, as shown in FIG. 4, this cover 4 has a sheet portion 42 such as a thin metal plate or metal foil integrally interposed on the back side of the cover 4 to improve its adhesion to the hard substrate 1. can be increased. The cover 4 may be made of any material as long as it has good adhesion to the hard substrate 1, but it is preferably made of the same material as the anti-slip material 2. Furthermore, it is also possible to form an uneven portion 21 on the upper surface of this cover 4, similar to that attached to the anti-slip material 2.
As shown in the figure, if the surface is made flat and the upper surface is positioned slightly lower than the concave portion of the anti-slip material 2 as shown in FIG. When cleaning both ends of the non-slip A, it can be used as a cleaning opening, which is more convenient.

【Effect of the invention】

As is clear from the above description, according to the present invention, since the anti-slip material is integrally formed on the upper surface of the hard substrate during molding, the overall thickness can be reduced and safety can be improved. In addition, since both ends of the hard board are fixed to the stairs with fasteners, the bonding strength is higher than when only adhesive is used. can be effectively prevented. Furthermore, since the head of the fastener is covered by the cover, it is possible to obtain a non-slip for stairs with a good appearance.
