[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall plan view of the present invention, FIG. 2 is a side view of FIG. 1, FIG. 3 is a perspective view of a main part, and FIG. 4 is a cross-sectional view taken along line AA of FIG.

1 and 2, reference numeral 1 denotes a snow melting mat. The snow melting mat 1 is, for example, a mat body 2 made of rubber, resin, or the like, and a center portion of one side 3 of the mat body 2. A power plug 4 is provided. The power plug 4 is a waterproof plug. Here, at a connection portion 5 between the power plug 4 and the mat body 2, a planar heating element (heating element) 6 provided in the mat body 2 over the entire surface of the mat body 2 as shown in FIG. Connected to plug 4. Here, the planar heating element 6 is of a planar shape, and is incorporated over the entire surface at a position that does not interfere with the anchor bolt 7 inside a mounting hole 8 of the anchor bolt 7 described later.

As shown in FIG. 3, a plurality of rib blocks 9 are arranged in blocks on the surface h of the mat body 2, and adjacent rib blocks 9 are arranged at predetermined intervals. The rib block 9 includes a rib base 10 formed in a square shape (square shape) when viewed from above, and the upper surface z of the rib base 10 is higher than the surface h of the mat body 2. Here, the size of the rib base 9 is desirably formed so that one side is about half the width of the shoe width and about 30 mm in order to sufficiently exert the anti-slip effect. The shape of the rib block 9 is not limited to a square, but may be a rhombus or a rectangle.

A plurality of ribs (irregularities) 11 are formed on the upper surface z of the rib base 10. The rib 11 has a cross-sectional shape in which the upper portion is angular, and is specifically formed in a triangular cross-section, and a plurality of ribs 11 are linearly arranged on the rib base 10 in a direction along the side. The shape is not limited to a triangular cross section as long as the upper portion has a square shape. Further, the direction of the rib 11 may be not necessarily linear but may be bent as long as it is linear. Here, the reason why the rib is linear is that the snow melt water flows smoothly when flowing into the groove 12 between the ribs 11 as described later. However, if the snow melt water can flow smoothly, the rib is curved. It may be configured in a typical manner.

As shown in FIG. 1, the rib blocks 9 are arranged so that the ribs 11 of the rib blocks 9 adjacent to each other have different directions. Specifically, when one rib block 9 in the portion B in FIG. 1 directs the ribs 11 in the up-down direction in FIG. 1, the right and left sides, and the upper and lower sides of the rib block 9 In each adjacent rib block 9, the direction of the rib 11 is the left-right direction.

Here, as shown in FIG. 3, since the ribs 11 are formed on the rib base 10, grooves 12 are formed between the ribs 11, and the grooves 12 are formed on the upper surface z of the rib base 10. It will be connected to. As described above, the rib blocks 9 are arranged on the surface h of the mat body 2 with a predetermined interval therebetween as described above. As a result, the guide grooves 13 are formed between the rib blocks 9. It will be. Mounting holes 8 are formed at predetermined intervals around the periphery of the mat body 2 configured as described above. Anchor bolts (fasteners) 7 are inserted through the mounting holes 8 so that the snow melting mat 1 is grounded. It can be fixed to

According to the above embodiment, if the snow melting mat 1 is laid, for example, in front of the entrance of a house, the power plug 4 is inserted into the power source, the anchor bolt 7 is inserted into the mounting hole 8 and fixed to the ground, Mat 1 can be installed. When snow accumulates on the mat body 2, the planar heating element 6 heats the mat body 2 over the entire surface, and the heat radiation area is increased by the ribs 11 of the rib blocks 9 of the mat body 2. As a result, the mat body 2 is uniformly heated up to the rib 11. Therefore, the heat dissipation effect is high and the snow can be melted by heating efficiently without the need for wasted power, and the power consumption can be reduced as compared with the case where there is uneven heating.

In addition, the ribs 11 can reliably prevent slippage. In particular, since the rib blocks 9 adjacent to each other are arranged so that the directions of the ribs 11 intersect in the orthogonal direction, A uniform anti-slip effect without bias can be exhibited. At this time, since the side portion of the rib block 9 is hooked, the rib block 9 itself can also exhibit a non-slip effect. Also, the snow on the back of the footwear can be scraped off by the ribs 11, and the rib block 9 itself also functions as a scraping portion for the mat body 2 for the same reason as described above, so that the snow can be efficiently removed. Can be scraped off.

Here, when the snow on the mat body 2 melts, the snowmelt water is guided to the upper surface z of the rib base 10 through the groove 12 between the ribs 11, and further flows downward to the surface h of the mat body 2. Is guided to the guide grooves 13 between the rib blocks 9, so that the drainage of the snowmelt water is smoothly performed. Therefore, freezing on the rib block 9 as in the case where the drainage is not performed smoothly does not occur. Therefore, there is no need to heat again as in the case of freezing again, and power consumption can be saved. Since the snowmelt mat 1 is fixed to the ground by the anchor bolts 7, the mat does not shift even in a strong wind, thereby preventing theft. Note that the present invention is not limited to the above embodiment. For example, instead of the rib block 9 (the thickness of the rib block 9 is eliminated), a plurality of block units are directly provided on the surface h of the mat body 2. Ribs 11 can also be provided. By doing so, the thickness of the mat body 2 can be reduced, so that there is an effect that the feeling of discomfort during use is reduced and the mat is easy to use.
