Description

[Detailed Description of the Invention] The present invention relates to an anti-slip device for preventing slips and falls when walking on slippery surfaces such as frozen roads or snow-covered roads. The present invention relates to an anti-slip device having a structure that allows the anti-slip device to be inverted and stored in a recess provided in the sole of footwear when walking on a normal road surface or an indoor floor surface.

Conventionally, when walking on frozen or snowy roads, the sharp anti-slip claws attached to the soles of footwear are activated to provide an anti-slip effect, but on the other hand, anti-slip effects are not required. Japanese Utility Model Publication No. 11-8255 discloses an anti-slip device that can be stored on the non-stepping side of the sole of the footwear so that the anti-slip device does not protrude beyond the contact surface of the sole of the footwear. The bottom anti-slip device has a metal fitting with a non-slip claw formed on the tip that can be turned over against the seat plate, but since there is no device to hold the metal fitting in any position, the metal fitting moves during use, so the anti-slip effect cannot be achieved. It has a drawback that it cannot be used reliably. The present invention solves the above-mentioned drawbacks of the conventional products, and when walking on slippery roads, the claws of the anti-slip device protrude from the ground surface to prevent ice from forming on the sharp tip of the claw. The anti-slip effect can be achieved by plunging into the footwear or snow, but when walking on regular roads or indoor floors, the anti-slip device can be turned over and stored in the recess provided in the sole of the footwear. The present invention relates to a non-slip device for the sole of footwear which can be installed in such a way that the device can be easily removed and the non-slip device can be replaced.

In the anti-slip device for footwear soles of the present invention, the anti-slip part is formed by bending a band-shaped body made of an elastic material into a horseshoe shape or a U-shape. The anti-slip part is provided with a shaft bent in a direction approximately perpendicular to the non-slip strip at the end of the straight part, and the non-slip part has a support part having a shaft hole and a hook having a lower edge. The anti-slip parts are placed on a retaining plate which is bent in the same direction so as to face both sides of the retaining plate perpendicularly to the plane of the retaining plate, and the axis of the anti-slip part is the axis of the supporting part of the retaining plate. The non-slip part is supported in a reversible manner using the shaft as a fulcrum, and one side of the linear part of the strip of the non-slip part is on either side of the hook part of the holding plate. Footwear that can be hung on the lower edge of the footwear and held in place, and the retaining plate can be fixed and held in a recess provided on the ground side of the sole of the footwear with a fixing device. It is a non-slip device for the bottom.

Next, one embodiment will be specifically described.

In order to perform the anti-slip effect using the anti-slip device of the present invention having the above-described structure, the anti-slip part 1 shown in FIGS. 1 and 2 is held as shown in FIGS. 3 to 5. Place it on the plate 5, pass the shaft 3 of the non-slip part 1 through the shaft hole 7 of the support part 6, and insert it into the gap E between the support part 6 and the guard part 16 so as to sandwich the straight part 4 of the non-slip part 1. By doing so, since the non-slip part 1 is made of an elastic material, the force of the straight part 4 to open outward is used to connect the A side or B side of the straight part 4 of the non-slip part 1 to the C side or D side of the hook part 8. As shown in FIGS. 6 and 7, the anti-slip portion 1 is assembled and held on the holding plate 5 so as to be hooked on the lower edge 9.

In this way, the anti-slip tool assembled with the anti-slip part 1 and the holding plate 5 is inserted into the fixing hole 10 of the holding plate 5.
1 to the inner surface of the recessed part 13 of the footwear sole 12, and as shown in FIG. Slide the anti-slip part 1 so that the tip of the part 2 protrudes from the ground surface 14.
is fixed to the holding plate 5.

When walking on a slippery road surface such as a frozen road surface or a snowy road surface while wearing footwear in which the anti-slip device according to the present invention is fixed to the concave portion 13 of the footwear sole 12 in the above-mentioned state, the tips of the claws 2 will dig into the road surface. This prevents you from slipping while walking.

When the anti-slip effect is unnecessary, such as when walking on a normal road surface, grip both sides of the anti-slip part 1 tightly, or further tighten the knob 1 of the anti-slip part 1.
5 and forcefully move it back and forth to remove the A side of the straight part 4 of the anti-slip part 1 from the C side of the lower edge 9 of the hook part 8, and then remove the straight part 4 from the gap E. While removing it, the front and back surfaces of the anti-slip part 1 are reversed using the shaft 3 as a fulcrum, and the anti-slip part 1 is stored in the front side of the concave part 13 as shown in FIG. At this time, the B side of the linear portion 4 of the anti-slip portion 1 is hooked onto the D side of the lower edge 9 of the hook portion 8 to securely hold it on the holding plate 5. By placing the anti-slip part 1 upside down in this way and storing and fixing it in the concave part 13 of the footwear sole 12, the claw 2 does not protrude from the ground surface 14, so it does not touch the road surface and there is no discomfort while walking. Moreover, it does not damage the road surface.

Note that the non-slip part 1 is fixed to the retaining plate 5 when the A side or B side of the straight part 4 of the non-slip part 1 is placed on the C side or D side of the lower edge 9 of the hook part 8 attached to the retaining plate 5. Since the hook and anti-slip part 1 is made of an elastic material, the straight part 4 can be held firmly by utilizing the force that opens outward. In order to prevent the shaft 3 from slipping out of the shaft hole 7 due to bending of the shaft 4, it is preferable to provide a guard section 16 inside the support section 6. Further, the gap E between the support part 6 and the guard part 16 is preferably a gap that allows the linear part 4 of the anti-slip part 1 to be inserted or removed, and that the shaft 3 does not displace from the shaft hole 7. .

To explain still another example, the 10th example
The anti-slip part 1 shown in Fig. 11 is shown in Figs.
Place it on the holding plate 5 shown in FIG. 14, pass the shaft 3 of the non-slip part 1 through the shaft hole 7 of the support part 6, and
The straight line part 4 of the hook part 8 is attached to the lower edge 9 of the non-slip part 1.
By inserting the straight part 4 of the anti-slip part 1
is made of an elastic material, so the force of the straight part 4 to open outward is used to connect the A side or B side of the straight part 4 of the anti-slip part 1 to the lower edge 9 of the C side or D side of the hook part 8.
As shown in FIGS. 15 and 16, the anti-slip portion 1 is assembled and held on the holding plate 5 so as to be hooked on the holding plate 5.

In this way, the anti-slip tool assembled with the anti-slip part 1 and the holding plate 5 is inserted into the fixing hole 10 of the holding plate 5.
1 to the inner surface of the recessed part 13 of the footwear sole 12, and the A side of the straight part 4 of the anti-slip part 1 is fixed to the hook part 8.
The anti-slip part 1 is firmly fixed to the holding plate 5 so that the tip of the claw 2 protrudes from the ground surface 14.

When used in the above conditions, the same anti-slip effect as in the previous embodiment can be obtained.

When the anti-slip effect is unnecessary, such as when walking on a normal road surface, grip both sides of the anti-slip part 1 tightly, and
The side of the anti-slip part 1 is removed from the C side of the lower edge 9 of the hook part 8, and then the front and back surfaces of the anti-slip part 1 are reversed using the shaft 3 as a fulcrum and stored in the front side of the recessed part 13. At this time, the B side of the linear part 4 of the anti-slip part 1 is hooked onto the lower edge 9 of the D side of the hook part 8 to be firmly fixed on the holding plate 5. By inverting the claw 2 in this way, the claw 2 is retracted and the same effect as in the previous embodiment can be obtained. The anti-slip tool of the present invention has one to five claws 2 on each side of the edges of the horseshoe-shaped or U-shaped curved shape of the anti-slip part 1, centering on the top of the non-slip part 1, i.e., two to five claws in total on both the left and right sides. By providing 10 pieces, claw 2
If only one pawl 2 is provided, the anti-slip effect will be small and unreliable, and if one pawl 2 is damaged, the anti-slip effect will be lost at all, which is inconvenient. In addition, when gripping the non-slip part 1, the tips of the nails 2 are sharp and you may get injured if you touch the sharp part. It is convenient to provide a knob 15 in one part. Of course, the anti-slip portion 1 may be bent diagonally to a height that does not protrude from the ground plane 14 of the sole 12 when the anti-slip portion 1 is fixed, or may be flat.

Further, the shaft 3 may be bent outward with respect to the anti-slip portion 1 as shown in FIG.
It may be bent inward as shown in Figure 0.
The support part 6 and the hook part 8 provided on the retaining plate 5 can be provided in any position as long as the anti-slip part 1 is firmly fixed on the retainer plate 5. 8 may be integrated as shown in FIG. 3, or may be provided separately as shown in FIG. Further, the support part 6, hook part 8, and guard part 16 provided on the holding plate 5 may be made by attaching the supporting part 6, the hook part 8, and the guard part 16 to the holding plate 5, which are made separately. A part of the holding plate 5 may be integrally formed by bending or the like.

The retaining plate 5 of the present invention is fixedly held within the concave portion 13 of the footwear sole 12 by a fixing device 11, and the fixing device 11 used in this case is a method using a completely fixed caulking nail. This includes both removable screws and methods using bolts and nuts.

As described in detail above, the 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, when walking on a slippery road surface such as a frozen road surface or a snowy road surface, the claw 2 is placed on the ground contact surface 14 side. By holding the anti-slip part 1 facing the opposite direction, the anti-slip effect can be exerted when walking, and when walking on a normal road surface or an indoor floor surface, the anti-slip part 1 is turned upside down and the sole 12 of the footwear is turned upside down.
By being stored in the concave portion 13 of the shoe, it has the advantage that it is possible to walk on it in the same manner as with ordinary footwear soles.

The product of the present invention has the advantage that it can be installed anywhere on the sole of footwear, and in the case of a footwear sole with a heel, a concave portion is provided in the heel so that it can be installed inside the concave portion of the heel.
