Description

[Detailed Description of the Invention] The present invention can prevent slips and falls when walking on slippery surfaces such as frozen roads or snow-covered roads, and can also prevent slips and falls when walking on normal roads or indoor floors. In particular, the present invention relates to a non-slip device having a structure that allows the non-slip device to be inverted and housed in a concave portion of a heel.

Conventionally, many footwear soles have been proposed for walking on slippery roads such as frozen roads and snow-covered roads. The soles of such footwear are those with anti-slip devices embedded in the soles of the footwear and fixed, or
- There are anti-slip metal fittings for shoe soles disclosed in Publication No. 27854, but the former is convenient because it has a sufficient anti-slip effect when walking on frozen or snow-covered roads. However, when walking on a normal road surface or an indoor floor surface, the sharp tip of the anti-slip tool comes into contact with the floor surface in a penetrating manner, which has the disadvantage of damaging the floor surface. In the latter case, when walking on frozen or snowy roads, the anti-slip metal fittings attached to the soles of the shoes are activated to provide an anti-slip effect, and when the anti-slip effect is not required, the anti-slip metal fittings are placed on the tip of the heel. Although it is convenient to use, it has an anti-slip effect in the front-rear direction when walking, but it does not have an anti-slip effect in the left-right direction. Furthermore, if the anti-slip fittings are damaged or worn out, they cannot be replaced.

The present invention eliminates the above-mentioned drawbacks of conventional products, and improves the anti-slip effect in the front-rear direction and left-right direction when walking by changing the position of the anti-slip part from the rear side to both side edges of the sole of the footwear. By placing it on the edge of the tool, it becomes a non-slip part that can be used both vertically and horizontally.

When walking on a slippery road surface, the present invention, which is a non-slip device having the above-mentioned structure, has the main body of the non-slip device facing the ground surface and the sharp part at the tip of the non-slip portion hits the ice or snow. On the other hand, when walking on normal roads or indoor floors, the anti-slip side of the anti-slip device should be tilted at right angles to the guide, and then the base side of the anti-slip device should be folded down at right angles to the guide. Slide the shaft part to the groove end at the other end of the guide groove, then tilt it further at a right angle in the same direction as before to position the anti-slip device body on the same plane as the guide, and then insert the entire body into the storage part provided in the sole of the footwear. It is a non-slip device that is installed so that it can be stored.

In the present invention, one side of the anti-slip tool main body 1 is made of a flat metal plate having a suitable shape and has a cutout 6 cut out in the center, and a shaft 2 has axle stops 5 on both sides thereof. There is a part 4, and a non-slip part 3 is bent at the edge of the anti-slip device body 1 from the side facing the base 2 to both side edges thereof, and is bent approximately at right angles to the plane of the non-slip device main body 1. The tip of the anti-slip part 3 is pointed in a triangular shape, and guides the shaft part 4 in the length direction of two parallel guides 7 that hold the shaft part 4 of the anti-slip tool body 1. The guide 7 can be slid along a groove 9 bored in the groove 9, and groove ends 10 are provided at both ends of the groove 9, and a guide base 8 is provided on the guide 7. The shaft part 4 of the anti-slip tool body 1 is passed through the groove 9, and shaft stops 5 are attached to both ends of the shaft part 4 to prevent the anti-slip tool main body 1 from falling off. As a result, the shaft part 4 can slide to the groove 9 and the groove end 10, and the shaft part 4 can be rotated at the position of the groove 9 and the groove end 10, so that the anti-slip tool main body 1 can be placed facing up or down. This made it possible. As a result, the structure is such that the anti-slip device main body 1 can be stored in a recess provided on the ground side of the sole of the footwear, or the anti-slip portion can be protruded from the bottom surface of the footwear. In this case, the shaft stop 5 attached to the end of the shaft portion 4 can be either a completely fixed caulking nail or a removable screw, bolt, or nut.

Next, the present invention will be further explained with reference to the drawings.

The figures show an embodiment of the anti-slip device according to the present invention, and FIG. 1 is a perspective view of the anti-slip device of the present invention, FIG. 2 is a perspective view of the guide, and FIG. 3 is the anti-slip device and the guide. FIG. 4 is a side sectional view illustrating how the anti-slip device is attached to the sole of the footwear when anti-slip is required, and FIG. FIG. 6 is a side sectional view of the anti-slip device stored inside the sole of the footwear when the anti-slip device is not needed, and FIG. FIG.

In the figure, reference numeral 1 denotes a non-slip device main body, which is provided with a base 2 on one side and a shaft portion 4 with axle stops 5 at both ends of the base 2, with non-slip portions extending from the opposite side of the base 2 to both edges thereof. 3 is provided. Furthermore, a cutout 6 is cut out approximately in the center of the anti-slip tool main body 1. 7 is a guide, and a guide base 8 is provided so that the guide 7 can be easily held. Further, a groove 9 is provided in the length direction of the guide 7, and groove ends 10 are provided at both ends of the groove 9. That is, the anti-slip device according to the present invention connects the two guides 7 to the anti-slip device main body 1.
The shafts 4 are lined up parallel to each other in a width that allows them to move, and the shafts 4 are inserted into the grooves 9 of the guide 7, and the non-slip device body 1 is placed so that the non-slip portion 3 faces the ground surface on the rear side of the sole 12 of the footwear. The footwear sole 1 is attached to the stopper 11 provided on the footwear sole 12 so that the shaft portion 4 of the footwear is attached to either one of the groove ends 10 so as to be in contact with the edge of the cutout portion 6.
It is fixed to a concave portion 13 provided on the ground surface side of No. 2.

In order to perform the anti-slip effect using the anti-slip device according to the present invention having the above-described structure, it is necessary to slide the anti-slip part 3 on the rear side of the sole 12 so that it faces the ground surface side, as shown in FIG. The stopper main body 1 is held. Of course, the anti-slip device main body 1 is fixed in the concave part 13 of the footwear sole 12 so that the tip of the anti-slip part 3 protrudes from the ground plane 14 and the top surface of the guide 7 fits within the sole of the footwear.

The anti-slip device main body 1 is held by being hooked onto the edge 6a of the cutout 6 by a stopper 11 provided in a protruding manner in a concave portion 13 of a sole 12 of the footwear. That is, as shown in FIGS. 3 and 4, by bringing the edge 6a of the cutout 6 into contact with the stopper 11 at two or more locations, it is firmly held and the holding position of the anti-slip device body 1 is prevented from shifting during wear. It is possible to prevent this.

In such a state, when walking on a frozen road surface or a snowy road surface wearing footwear in which the anti-slip device according to the present invention is fixedly held in the concave portion 13 of the footwear sole 12, the anti-slip portion 3
Since the tip of the shoe bites into the road surface, it is possible to prevent slipping in the longitudinal and lateral directions when walking.

The reason why the anti-slip portion 3 is provided at two or more locations from the rear end of the side facing the base 2 to both side edges is that one location only has an anti-slip effect in a specific direction, but two locations are provided. This is because, as can be seen from FIGS. 1 and 7, the anti-slip effect is exhibited in any direction.

If there is no need for an anti-slip effect when walking on a normal road surface, as shown in FIG. Next, the shaft part 4 of the base part 2 is slid to the opposite side along the groove 9 as shown by the arrow B to the position of the groove end 10 on the opposite side, and from this groove end 10 as a starting point, the anti-slip part 3 side is moved to the footwear sole 12.
It is folded down into the recessed part 13 and stored as shown in FIG. 6, and is stored and held by the stopper 11 to prevent the slip stopper main body 1 from wobbling. Fold down the anti-slip device body 1 and insert the anti-slip device body 1 into the concave portion 1 of the footwear sole 12.
By storing and holding the anti-slip part 3 in
Since the anti-slip portion 3 is stored in the front side of the concave portion, the anti-slip portion 3 does not come into contact with the road surface when walking, so there is no discomfort and there is no damage to the road surface.

In addition, when raising the non-slip part 3, the tip of the non-slip part 3 is sharp and if you touch the sharp part, you may get injured, and if you are wearing gloves, it will be difficult to grasp the non-slip part 3. If this is difficult, it can be made easier to raise by providing a knob 15 on the side of the anti-slip tool body 1 facing the base 2, as shown in FIG. Of course, it is bent on the same plane as the anti-slip device body 1 or diagonally so that it does not protrude from the ground surface of the sole of the footwear when the anti-slip device body 1 is held.

The shape of the stopper 11 is the same as the shape of the edge 6a of the cutout part 6 of the anti-slip tool body 1, and the upper side is shaped like a flap to make it easier and stronger to hold the anti-slip tool main body 1. Further, it may be embedded and fixed in the inner surface of the recessed part of the footwear sole 12, or it may be fixed removably with a screw or the like.

In addition, the height of the stopper 11 is 1
Of course, the height of the cutout 6 may be such that it does not easily slip out, and it is preferable that the cutout 6 does not protrude beyond the ground contact surface of the sole of the footwear. The stopper 11 can also be formed by providing a convex body made of the same material as the footwear sole and having the same shape as the cutout 6 on the inner surface of the concave portion of the footwear sole.

The shaft stops 5 of the shaft 4 attached to both sides of the base 2 of the anti-slip tool body 1 may be completely fixed to the shaft 4 with caulking rivets or the like, or they can be attached and removed using screws, bolts, nuts, etc. may be fixed. In the case of wear or damage of the anti-slip part 3, it is preferable to make it removable in order to replace it.

The shape of the anti-slip device main body 1 may be any shape such as a rectangular, triangular, semicircular, or horseshoe shape, and the anti-slip portion 3 may also be formed by forming one or both of the outer peripheral edge of the non-slip device main body 1 or the cutout edge. It may also be placed at the edge.

The shape of the cutout 6 can be freely selected such as rectangular, triangular, circular, semicircular, etc. The cross-sectional shape of the guide 7 can also be L-shaped or T-shaped if the guide base 8 is easily fixed.
The shape of the groove 9 may be any shape such as a straight line, an arc, a U-shape, a square shape, an S-shape, etc. so that the shaft portion 4 can be easily slid and it can be easily accommodated in the groove end 10. Good to have. Also, two parallel
The guides 7 may be connected by one guide base 8.

As detailed above, the footwear in which the anti-slip device according to the present invention is fixed to the concave part of the sole of the footwear is designed so that the anti-slip part 3 faces the ground when walking on a slippery road surface such as a frozen or snow-covered road. By placing the anti-slip device in place, the anti-slip effect can be exerted in the front-rear direction and left-right direction when walking, and when walking on normal roads or indoor floors, the anti-slip device body 1 can be tilted approximately 90 degrees. Then slide it to the other groove end, and then pull it down further in the same direction by about 90 degrees to store the anti-slip device body 1 in the concave part 13 of the footwear sole 12, so that it is no different from a normal footwear sole. It has the advantage of being able to walk. Also guide 7 and stopper 1
