[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a cross-sectional view of a main part showing a state in which the ice-and-snow prevention mat for stairs of the present invention is laid on the stairs.

The stair ice protection mat for stairs of the present invention has a three-layer structure of a front rubber layer 1, an intermediate sponge layer 2 and a back rubber sheet layer 3, and the back rubber sheet 3 has a removable convex portion 4. It is provided. The attaching / detaching convex portion is provided so as to penetrate from the front surface rubber layer 1 to the intermediate sponge layer 2 and the rear surface rubber sheet layer 3. On the other hand, the tread surface of the stairs 7 is provided with a concave portion 5 that fits with the convex portion 4. The convex portion 4 and the concave portion 5 are firmly fitted to each other, so that the stair ice accretion prevention mat is fixed to the step surface of the stair 7. Since the convex portion 4 and the concave portion 5 are merely physically fitted, it is easy to remove the step ice accretion prevention mat.

Further, since the rubber sheet 3 is integrally formed on the back surface of the stair ice-accumulation prevention mat of the present invention, the sponge layer 2 is prevented from partially containing water, and the sponge layer 2 is prevented. It is possible to prevent the deterioration of the layer 2.

The convex portion 4 and the concave portion 5 of the present invention may be formed of, for example, metal, plastic, or thermoplastic elastomer, or a combination of respective materials, and the material is not particularly limited.

In order to prevent slippage, it is preferable to provide a plurality of recessed stripes 6 in the longitudinal direction in the stair ice protection mat for stairs of the present invention. Even if snow or ice adheres to the stair ice accretion prevention mat, the sponge layer 2 bends due to the pressure at the time of stepping on, and the ice accretion cracks, so the ice accretion snow does not continue to adhere to the mat body.

The material of the anti-icing snow mat for stairs of the present invention is not particularly limited, but as the front and back rubber, natural rubber (NR), styrene butadiene rubber (SBR), butadiene rubber (BR), chloroprene rubber (CR), ethylene propylene rubber (EPDM) and other rubber polymers, in order to impart cold resistance, in consideration of the combination with rubber polymers and softeners, additives such as ordinary fillers and crosslinking agents. In addition to that, processed products can be mentioned.

The material of the intermediate sponge layer is not particularly limited as long as it is elastic and has a certain hardness, but it is the same as the upper rubber material in that it is easy to manufacture, such as natural rubber (NR) and styrene. Foaming is performed by adding a foaming agent to rubber polymers such as butadiene rubber (SBR), butadiene rubber (BR), chloroprene rubber (CR) and ethylene propylene rubber (EPDM) together with usual fillers, crosslinking agents and other additives. The foamed rubber described above is preferred. It should be noted that the sponge is not preferable because if it is not a single foam, the melted water of rain or ice and snow is taken into the inside of the sponge, and when it becomes below freezing, the water freezes and loses elasticity. Further, the intermediate sponge layer has only to have a hardness such that it can be appropriately flexed by the stepping pressure, and for example, one having a hardness in the range of Hs5 to 30 (Type-C for sponge) is preferable.

FIG. 2 shows a second embodiment of the present invention. 2A is a perspective view showing the second embodiment, and FIG. 2B is a sectional view taken along the line AA. In the second embodiment, in order to avoid the risk of hitting the stairs or the corners of the steps at the corners of the stairs and receiving cuts, bruises, fractures, or other injuries during a fall, the second embodiment is provided on the front side of the ice-and-snow prevention mat for stairs. The stepped corner cushioning member 8 having a substantially L-shaped cross section is provided, and the flat cushioning covering member 9 is provided on the side surface of the short side of the mat.

The staircase corner portion cushioning covering member 8 has a substantially L-shaped cross section including a vertical portion 8-1 and a horizontal portion 8-2 made of a soft elastic member, and a rear end of the horizontal portion 8-2. An overhanging portion 8-3 is provided on the mat, and the overhanging portion 8-3 and the mat body are bonded to each other.

The stepped corner cushioning cover portion 8 having a substantially L-shaped cross section and the flat cushioning coating portion 9 may be preliminarily formed integrally with each other in a U-shape. By integrally forming the staircase corner cushioning portion 8 having a substantially L-shaped cross section and the flat cushioning coating portion 9 into a U-shape, it is possible to simplify the labor of adhering the cushioning coating portion at the time of construction. You can improve the aesthetics of the anti-icing snow mat for stairs.

Although not shown in FIG. 2, the surface rubber layer 1 of the main body of the mat, the stepped corner cushioning portion 8 having a substantially L-shaped cross section, and the flat cushioning coating portion 9 are used to prevent slippage. You may provide several uneven lines.

As a third embodiment, a detachable convex portion is provided so as to penetrate only the back rubber sheet layer 3. FIG. 3A is a perspective view showing a third embodiment, and FIG. 3B is a sectional view taken along the line BB of FIG. Since the attaching / detaching convex portion is provided so as not to penetrate the front surface rubber layer 1 but to penetrate only the back surface rubber sheet layer 3, the head portion of the attaching / detaching convex portion does not appear on the surface rubber layer 1. , You can keep the appearance beautiful.

The staircase corner cushioning cover of the present invention is preferably made of a soft elastic member in order to reduce the impact on the body during a fall. Examples of such a soft elastic member include rubber-based compounds such as natural rubber (NR), styrene-butadiene rubber (BR), chloroprene rubber (CR), ethylene-propylene rubber (EPDM), styrene-based (SBC), Examples of the material include one of thermoplastic elastomers (TPE) such as vinyl chloride (TPVC) and olefin (TPO), or a combination of two or more thereof.
