Description

  The present invention relates to an anti-slip device for shoes, and more particularly to an anti-slip device for shoes that can prevent slippage on both ice and snow road surfaces and rainwater road surfaces.

  Patent Document 1 discloses an anti-skid tool for shoes composed of a rubber band. By pulling and stretching the band, it can be easily attached to the shoe. A metal spike for preventing slipping is provided at the bottom of the stopper, but the spike pin is exposed, so if you walk on the concrete road surface, marble inside the building, P tile, concrete, shears, etc. There is a problem with the sound of hitting.

  The shoe anti-skid tool of Patent Document 2 is provided with a groove for preventing slippage on a rainwater road surface and a spike for preventing slippage on an ice and snow road surface at the bottom. The spike is embedded in the rubber of the grounding part, and the top of the pin of the spike is at the same or slightly lower position as the surface of the grounding part, so the marble, P tile, concrete, timber, etc. in the concrete road surface and building It is said that no striking sound will be produced even if you walk on it. In addition, it can be used throughout the year because slippage on the rainwater road surface is prevented.

  However, since the spike pin is embedded in the rubber of the grounding part of the anti-slip device for shoes, if the rubber is soft, the rubber will shrink and the pin will protrude each time you walk, and if the rubber is hard There is a possibility that the pin does not protrude and the anti-slip function on the icy and snowy road surface does not work sufficiently.

In addition, if the distance between the grooves of the grounding part is wide, the grounding area of the grounding part will be large as a whole, the amount of dents in each part will be small, and even if soft rubber is used, the spike pin will not protrude much . Conversely, when a rod-shaped or rectangular projection like the shoe sole of Patent Document 3 is provided and the spike pin is housed therein, the ground contact area of the ground contact portion becomes smaller as a whole, and the amount of dent in each part is As you walk, the pins stick out each time you walk. That is, there are many problems with the structure in which the spike pin is protruded by the expansion and contraction of the entire grounding portion of the anti-skid tool for shoes.

  The object of the present invention was made to solve the above-mentioned problems, and the object of the present invention is to provide an anti-slip device for shoes that is easy to use and has an improved anti-slip function on icy and snowy road surfaces. It is in. Another object of the present invention is to improve the grip performance on the icy and snowy road surface by improving the shape of the protrusion that prevents slipping on the rainwater road surface.

  In order to achieve the above object, an anti-skid device for a shoe according to claim 1 according to the present invention is made of soft rubber, and is provided with an anti-slip pad provided on both the toe side and the heel side, In the anti-slip device for soft rubber shoes made of a band, the anti-slip pad has a built-in spike with a plurality of pins protruding therein, and a pressure receiving body provided with a protrusion and a pin housing cylinder that is pushed into the lower end. An L-shaped projection body, and when the pushed projection is pressed by snow and snow on a road surface, the pressure receiving body is dented, whereby the pin housing cylinder is pulled up, and the pin housing cylinder is lifted from the top of the pin housing cylinder. Is characterized by protruding.

  According to a second aspect of the present invention, an outer frame protrusion having a height lower than that of the L-shaped protrusion, the pressed protrusion, and the pin housing cylinder is provided around the anti-slip pad.

  A third aspect of the present invention is characterized in that a high-intensity reflective material is attached to the rear side surface on the heel side of the band.

  According to the anti-slip device for shoes according to claim 1, since the protrusion is provided by being pushed into the pressure receiving body, if the solid of ice or snow is pushed and pressed against the protrusion, the pressure receiving body is dented, and the pin storage cylinder is removed. Since the pin is pulled upward, the spike pin can be protruded from the hole at the top of the pin housing cylinder. As a result, slipping on an icy and snowy road surface can be reliably prevented. Note that the pin of the spike protrudes from the top of the pin housing cylinder also when ice or snow solid presses the flat surface of the pressure receiving body. Although the area is small, even if ice or snow solids press the top of the pin housing cylinder, the pin protrudes from the hole. When walking on flat concrete, the spikes do not protrude and no hitting sound is produced.

  In addition, the plurality of L-shaped protrusions arranged around the pressure receiving body are effective in preventing slipping on a flat ice surface because the right-angled corner portions are easy to bite into ice or snow. Of course, even on a curved road surface or an inclined road surface such as a slope, the L-shaped right-angled portion easily bites into ice or snow, so that slip can be prevented. Note that the L-shaped protrusions can prevent slippage on the rainwater road surface because rainwater escapes through the L-shaped protrusions on the rainwater road surface.

  According to the second aspect, since the outer frame protrusion is provided around the anti-slip pad, the protruding amount of the L-shaped protrusion, the pressed protrusion, and the pin housing cylinder can be determined. For example, if there is no outer frame protrusion, the height of the L-shaped protrusion cannot be made too high, and the pressure receiving body that is pushed in and has the pin housing cylinder cannot be removed. The outer frame protrusion can increase the weight of the rubber to increase its weight, thereby providing stability when the shoe anti-skid tool lands.

  According to the third aspect, since the high-intensity reflecting material attached to the rear side surface on the heel side of the band shines with the headlight of the car, the visibility of the driver can be improved.

  Hereinafter, an antiskid device for shoes according to the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view of a shoe antiskid device according to the present invention. The anti-skid tool 20 for shoes is made of soft rubber, has a toe hook band 1 at the front, a heel band 2 at the rear, and an intermediate band 3 between them. When attaching the shoe anti-skid tool 20 to the shoe, insert the tip of the shoe into the toe strap 1, hold the tab 4 and stretch it backwards, and enlarge the opening of the heel strap 2 to the heel of the shoe. Fit. The thickness of the band is 1 mm, and the overall length is about 20 cm as an example. The extension amount of the intermediate band 3 can be increased to provide a free-size shoe anti-skid device suitable for shoe sizes of 22.5 to 27 cm. The soft rubber may be synthetic rubber or natural rubber. A high-intensity reflective material 14 was attached to the rear side surface of the heel hook band 2. Thereby, since light reflects, the visibility from the driver | operator of a vehicle is improved.

  FIG. 2 is a rear view of a shoe antiskid device according to the present invention. An anti-slip pad 5 on the toe side and an anti-slip pad 6 on the heel side are provided on the ground contact surface of the anti-skid tool 20 for shoes. These anti-slip pads 5 and 6 are surrounded by an outer frame protrusion 9, and a pressure receiving body 7 and an L-shaped protrusion 8 are provided inside thereof. The pressure receiving body 7 is made of soft rubber, and the anti-slip pad 5 has three and the anti-slip pad 6 has one. As shown in the drawing circle C1, the L-shaped protrusion 8 is a soft rubber having a flat side that becomes the ground contact surface. On the rainwater road surface, the rainwater that has been treaded passes between the L-shaped protrusions 8 and escapes to the outside of the shoe anti-skid device, so that the L-shaped protrusions can contact the road surface and therefore do not slip. The L-shaped protrusion 8 is arranged such that the longitudinal direction is directed to the left 45 degrees or the right 45 degrees. In that case, the right-angled portion of the L-shaped protrusion 8 can be arranged in any direction, up, down, left, or right while maintaining this angle. The right-angled part aims to cut into the snowy snow and make it hard to slip. Note that not only the L-shaped protrusion 8 but also a part of the rectangular protrusion 19 may be used together.

  FIG. 3 is a right side view of the anti-skid tool for shoes according to the present invention. The anti-skid tool 20 for shoes is attached to the heel of the shoe by first inserting the tip of the shoe into the toe hook band 1 and then pulling the tab 4 as shown by the arrow to widen the opening and extending backward. To do. As shown in the drawing circle C1, the outer frame projection 9 is not limited to this, but the height (indicated by h1) is 5 mm, the thickness is 3 mm, and the bottom of the non-slip pads 5 and 6 is stable. Is given. Further, the outer frame protrusion 9 has an endless shape in the anti-slip pad 5, but the anti-slip pad 6 is cut halfway. The height of the L-shaped protrusion 8 is higher than the height h1 of the outer frame protrusion 9, as indicated by h2. Accordingly, the rainwater that has been stepped on escapes beyond the wall of the outer frame projection 9 to the outside. Assuming that rainwater confined in the outer frame projection 9 is compressed, the outer frame projection 9 may be provided with a portion cut in the middle. The L-shaped protrusion 8 can increase the ground contact area as compared with a rod-shaped protrusion and the like, and the corner portion is wedge-shaped, so it can bite into ice and snow.

  As shown in the drawing circle C1 of FIG. 3, the pressure receiving body 7 is made of soft rubber and has a spike 10 incorporated therein. As shown in FIG. 2, the pressure receiving body 7 is a rectangular body, and is pressed on the lower side (grounding surface side) to be provided with a protrusion 15 and a pin housing cylinder 16. The pin housing cylinder 16 is provided with a hole through which the pin 11 of the spike 10 protrudes. In the present embodiment, the height of the pressure receiving body 7 is h1, and the height of the pushed-in projection 15 and the pin housing cylinder 16 is h2 in accordance with the height of the L-shaped projection 8. Therefore, the pin 11 of the spike 10 is not exposed on the flat ground surface. Since the cross-sectional shape of the pushed-in projection 15 and the pin housing cylinder 16 is triangular, the corner portion is wedge-shaped in the horizontal direction, and it is not limited to a flat road surface, and it bites into ice and snow on an inclined road surface. Cheap. As an example, in the case of a rough road surface of ice or snow, if the protrusion of the ice or snow is stepped on and the protrusion 15 is pushed upward, the pin storage cylinder 16 is also lifted upward, and the spike 10 The pin 11 is exposed.

  As shown in the drawing circle C2 of FIG. 3, the spike 10 is made of metal in which a through hole 13 is provided in the base 12 and four pins 11 are erected around the periphery.

  FIG. 4 is a perspective view of a pressure receiving body according to the present invention. (A) is the perspective view seen from the front side, (b) is the perspective view seen from the back side. The pressure receiving body 7 has a pushed-in projection 15 and a pin housing cylinder 16 that are in contact with the ground contact surface. The pin housing cylinder 16 is provided with a pin projection hole 17. A spike 10 is mounted inside the pressure receiving body 7. A pressure receiving body 7 as shown in FIG. 4 may be prepared in advance and attached to the anti-slip pads 5 and 6 with an adhesive. The pressure receiving body 7 may be integrally formed with a mold for manufacturing the anti-skid tool 20 for shoes.

  FIG. 5 is an operation diagram of the pressure receiving body according to the present invention. When the pressure-receiving body 7 including the projection 15 is pushed in when the shoe is landed and steps on a block of ice or the like, the pressure-receiving body 7 contracts and pulls up the pin housing cylinder 16 so that the pin 11 of the spike 10 protrudes downward.
