[Technical field to which the invention belongs]

 The present invention relates to an ice and snow prevention mat that prevents icing and snow in cold regions and prevents a fall accident due to a pedestrian's slip.

[0002]

[Prior art]

 In cold regions in winter, pedestrians have slipped on solidified snow and ice, causing accidents that caused them to fall, which has become a problem. This fall accident occurs frequently on outdoor stairs, entrances, steps on pedestrian crossings, and steep slopes. Conventionally, in order to prevent such a fall accident, a method of embedding an electric heater or a hot water pipe in a road or a floor to melt snow, or to prevent the formation of icing and snow consisting of a rubber layer and a sponge layer as disclosed in Utility Model Registration No. 3013195. It has been proposed to lay mats for use. In the two-layered mat for preventing icing and snow, the lower sponge layer bends when stepped on, and the ice and snow fixed on the surface is broken by the elasticity of the deformation and return, thereby preventing slip.

[0003]

[Problems to be solved by the invention]

 However, the method of embedding an electric heater or hot water pipe to melt snow is extremely effective in preventing falling accidents due to slippage because snow and ice do not stick. It is necessary and cannot be installed easily, and there is a problem that maintenance costs such as construction costs and utility costs for melting snow are required.

In addition, the mat for preventing icing and snow having a two-layer structure of a rubber layer and a sponge layer disclosed in Utility Model Registration No. 3013195 has a short life and a short deterioration because the sponge layer is exposed to the outside. There is a problem that the melted water of snow and ice penetrates into the sponge layer, and when the temperature falls below the freezing point, the water freezes, and the elasticity of the sponge layer is lost and the sponge layer does not exhibit its effect. For this purpose, sponges that have been independently foamed have been devised.However, the closed cells are broken over time and communicate with each other, causing the water to contain water. is there.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing an embodiment of the present invention, and FIG. 2 is a sectional view taken along line AA of FIG. In FIG. 1, an icing and snow prevention mat 1 is formed of a hollow mat body 2 having irregularities 4 for preventing slippage on the surface thereof. In the present embodiment, the irregularities 4 are formed by arranging four-sided pyramid-shaped protrusions, but the present invention is not limited to this. Absent. The mat body 2 is formed of a rubber material having elasticity.

The rubber material is preferably used as a cold-resistant rubber material because the present invention is used in cold regions, and natural rubber (NR), styrene-butadiene rubber (SBR), butadiene rubber (BR), chloroprene Rubber compounds having a rubber polymer such as rubber (CR) or ethylene propylene rubber (EPDM) as a main component and imparting cold resistance thereto can be exemplified.

According to the icing and snow prevention mat 1 according to the above-described embodiment, when the mat body 2 is stepped on, the mat body 2 is formed of a rubber material so that the mat body 2 is fixed to the surface by bending deformation, vibration, and bounce. Ice and snow are broken, preventing slippage. When the pedal pressure is removed from the mat body 2, the mat body 2 is restored by elastic force. The elastic force of the icing and snow prevention mat 1 is determined by the hardness of the rubber material forming the mat body 2 and the air pressure filled in the hollow 3 of the mat body 2.

FIG. 3 is a cross-sectional view showing another embodiment of the present invention and corresponding to the line of FIG. 1A-A. In this example, the hollow portion 3 of the mat body 2 is filled with a sponge 6, and the other components are the same as those of the above-described embodiment. Therefore, the same components are denoted by the same reference numerals, and detailed description is omitted. According to the present embodiment, since the sponge 6 is filled in the hollow portion 3 of the mat body 2, it is not necessary to maintain the air pressure by sealing the hollow 3 in a water-tight manner, and it is possible to guarantee the bending deformation and the resilience. Since there is no sudden deformation when stepping on, the feeling of stepping on the mat body 2 is reassuring, and the inconvenience such as a hole in the mat body 2 is eliminated. Also, it functions even if the mat body 2 has a hole. The elastic force of the icing snow prevention mat 1 is determined by the hardness of the rubber material forming the mat body 2 and the hardness of the sponge 6. When the hollow 3 of the mat body 2 is closed in a watertight manner, the air pressure filled in the hollow 3 also has an effect.

In the icing and snow prevention mat 1 according to this embodiment, the back surface of the mat body 2 is formed in the concave portion 3a, and after filling the concave portion 3a with the sponge 6, the opening 3b of the concave portion 3a is sealed with the bottom plate 5. It can be manufactured by

FIG. 4 is a cross-sectional view, corresponding to FIG. 1A-A, showing still another embodiment of the present invention. The icing and snow prevention mat 1 comprises a mat body 2 having a back surface formed of a rubber material in a concave portion 3a, and a sponge 6 filled in the concave portion 3a of the mat body 2, and the concave portion 3a is partitioned by a partition wall 9. Each of the divided compartments is filled with a sponge 6, and the mat body 2 is cut from the partition 9 so that the size can be adjusted. Therefore, the same components are denoted by the same reference numerals, and detailed description is omitted. According to this example, since the size can be adjusted in addition to the same operations and effects as those of the above-described embodiment, the laying can be performed in a manner that exactly matches the area of the place of use.

FIG. 5 is a cross-sectional view showing still another embodiment of the present invention, and the same components as those in the above embodiment are denoted by the same reference numerals. This example is composed of a mat body 2 having a back surface formed of a concave portion 3a made of a rubber material, a bottom plate 6 for sealing an opening 3b of the concave portion 3a, and a sponge 6 filled in the concave portion 3a of the mat body 2. The bottom plate 5 is fixed to the installation place 8 in advance by fixing means 7, and the mat body 2 filled with the sponge 6 is fixed to the bottom plate 5 so that the opening 3b of the concave portion 3a is sealed. Things. Although the fixing means 7 is shown as a screw nail in this embodiment, the present invention is not limited to this fixing means, and other fixing means such as nails, tacks, adhesives and the like may be used. According to this example, the fixing means 7 does not appear outside, so that the appearance can be kept beautiful.

The material of the sponge 6 is not particularly limited as long as it has elasticity and a certain hardness. For example, natural rubber (NR), styrene butadiene rubber (SBR), butadiene rubber (BR), chloroprene rubber (CR), ethylene propylene rubber (EPDM), and other polymers are mixed with a foaming agent and a normal filler and a crosslinking agent. And foamed rubber that has been added and foamed. If the melted water of snow or ice enters the sponge 6, the sponge 6 freezes below the freezing point and loses its elasticity. Therefore, the sponge 6 is preferably foamed independently. Since it is sealed, there is no invasion of moisture, so that it does not necessarily have to be foamed alone. However, if the foam rubber is a single foam, the sealing of the hollow 3 is not ensured, and the sponge 6 does not contain water even if moisture enters the hollow 3, so that the reliability is improved.

[Effect of the invention]

 As described in detail above, the mat for preventing icing and snow according to the present invention has the following effects. (1) When stepping on, the mat body and the sponge bend and deform, and the icing snow breaks, and the icing snow does not continue to adhere to the mat body, thereby preventing a fall accident due to a slip caused by the icing snow.

(2) Since the mat body is made of a rubber material and is hollow, when stepped on, the rubber material is elastically deformed by the air pressure and the hollow air pressure is deformed, and the ice and snow firmly fixed to the surface is broken by vibration and bounce. A slip accident is prevented (claim 1).

(3) If the concave portion on the back surface of the mat body is sealed with a bottom plate to form a hollow portion, it is easy to manufacture and can be provided at low cost (claim 2).

(4) Since the sponge is attached to the hollow portion of the mat body, it is not exposed to the outside, and the sponge is less likely to deteriorate and has a long life (claims 3, 4, and 5).

(5) Since the sponge is sealed in the hollow portion of the mat body, moisture does not enter into this hollow portion, and therefore, the sponge does not contain moisture, and freezes to have elasticity. I do not lose. Therefore, when a foamed rubber is used as the sponge, it may be a single foam or a continuous foam (claims 3, 4, and 5).

(6) Since the size of the mat body is adjustable, the mat body can be laid exactly in accordance with the area of the place of use. In particular, when a plurality of sheets are laid in succession, gaps of any width can be handled (claim 4).

(7) If the mat body is fixed to the bottom plate after fixing the bottom plate, mounting is easy and the fixing means does not appear to the outside, so that the appearance can be kept beautiful. (Claim 5).
