Description

[Detailed description of the invention] This invention has an anti-slip effect when walking on slippery surfaces such as frozen roads or snow-covered roads, but is effective when walking on normal roads or indoor floors. The present invention relates to a non-slip footwear sole having a structure that can be stored in a storage section provided in the footwear sole so as to prevent slippage from occurring.

A number of footwear have been proposed that are suitable for walking on slippery surfaces such as frozen and snowy roads, but most of these have anti-slip devices embedded in the footwear. This is convenient because it has an anti-slip effect when walking on frozen or snow-covered roads, but when walking on normal roads or especially indoor floors, it has a noticeable anti-slip effect. The equipment made it difficult to walk and caused damage to the floor, which was very inconvenient.

Furthermore, since the above-mentioned conventional anti-slip devices were embedded in the sole of the footwear, they had the disadvantage that if the anti-slip devices were worn out, they could not be replaced.

In view of the above-mentioned shortcomings of conventional products, in the present invention, as a result of various research and ingenuity, a non-slip device is attached that has an anti-slip effect in the front and back direction and left and right side directions when walking.
The mechanism is such that the anti-slip effect can be achieved by inverting the anti-slip device, or the effect of its presence can be completely eliminated by completely retracting the anti-slip device.

In other words, when walking on a slippery road surface, the anti-slip device body is placed opposite the ground surface, but when walking on a normal road surface, the anti-slip device body is reversed and inserted into the storage area provided on the sole of the footwear. It can be stored and finished.

The present invention is a narrow frame in which one side of the anti-slip device main body 1 is cut out from a metal flat plate in the shape of an opening and has a cutout 5 having a generally square shape with an offshore center cut out, so that one side of the antislip tool body 1 dominates the rotating shaft portion 2. On the side facing the rotating shaft 2, a front-rear anti-slip part 3 is bent at a substantially right angle to the plane of the anti-slip tool body 1 and has a triangularly pointed tip. On the other two opposing sides, left and right lateral side anti-slip parts 4 similar to the front-rear anti-slip part 3 are provided, and approximately at the center in the length direction of the 6 that holds down the rotating shaft part 2 of the anti-slip tool body 1. A protruding portion 7 having a shape adapted to the rotating shaft portion is provided at the portion.
In addition, there is a stopper 8 with one end of the presser 6 bent almost at right angles to the plane of the presser 6, and fixing holes 9 are provided near both ends of the presser 6 in the length direction. It is inserted into the cutout 5 of the stopper main body 1, and the rotating shaft part 2 of the anti-slip tool main body 1 is mounted so that it can be rotated around the internal rotating shaft part 2 on the inner surface of the protruding part 7 of the holding tool 6. Moreover, the spring plate 10 is stacked on the back side of the presser 6, and the circumferential hole 9 provided at both ends of the presser 6 and the fixing hole 11 provided on the spring plate 10 are provided.
The presser 6, the spring plate 10, and the fixing plate 12 are fixed to the heel 15 by the fixing device 14 through the fixing hole 13 of the fixing plate 12 provided inside the heel 15.
This invention relates to a non-slip footwear sole characterized in that it is provided with a storage section 18 for storing the longitudinal anti-slip part 3 and the horizontal anti-slip part 4 of the anti-slip device main body 1, and in this case, the fixing device 14 is This includes both a completely fixed type using caulking nails and a removable type using screws and bolts.

Next, the present invention will be explained in more detail with reference to the drawings.

The drawings show one embodiment of the non-slip footwear sole according to the present invention. Fig. 1 is a perspective view of the anti-slip device used in the present invention, and Fig. 2 is a side view of the non-slip footwear sole when anti-slip is required. 3 is a plan view of the same, and FIG. 4 is a side sectional view of the heel portion of the anti-slip footwear sole when anti-slip is not required.

In the figure, reference numeral 1 denotes the main body of the anti-slip device, which has a rotating shaft portion 2 at one end, a longitudinal anti-slip portion 3 bent at almost right angles to the anti-slip device main body at the other end, and a longitudinal anti-slip portion at both ends. A side-slip prevention part 4 is provided which is bent in the same way as the stop part 3, and a cutout part 5 is cut out in the center of the center of the body through the presser.

Reference numeral 6 denotes a presser, and the presser 6 is provided with a substantially letter-shaped protrusion 7 in the center of the presser 6 toward the surface side of the presser, and one end of the presser 6 is approximately connected to the presser. It has a stopper 8 bent at a right angle, and fixing holes 9 for fixing the presser are provided near both ends of the presser around the protrusion 7.

Reference numeral 10 denotes a spring plate having substantially the same width and length as the holding tool 6, and a fixing hole 11 of the same size is provided at the same position as the fixing hole 9 provided in the holding tool 6.

Reference numeral 12 denotes a fixing plate having almost the same width and length as the presser, and has a fixing hole 13 of the same size at the same position as the presser, so that it can be incorporated into the heel 15. .

Pass the presser 6 through the cutout 5 of the anti-slip tool body 1, insert the rotating shaft portion 2 into the protruding portion 7, stack the spring plate 10 on the back side of the presser 6, and place the heel 15 on the contact surface side. The fixing hole 9 and the fixing plate 12 are integrated into the recess 17 provided in the heel 15 by means of a fixing device 14 in the recess 16 provided inside the heel 15, and the fixing hole 9 (through L 11.13 to the heel 15). Fixed.

Reference numeral 18 designates a storage part provided on the front side of the heel 15 for storing the anti-slip part 3 and the side-slip part 4 when the non-slip device main body 1 is turned over when the anti-slip part 1 is not needed, and is composed of a convex part A and four openings. has been done.

19 is a heel pattern provided around the heel 15 on the contact surface side.

That is, in the anti-slip footwear according to the present invention, the anti-slip part 3 and the anti-slip part 4 are provided on the inner surface of the approximately ■-shaped protrusion 7 provided at the center of the presser 6, and the anti-slip part 4 is attached to the ground contact surface on the rear side of the heel 15. The rotating shaft portion 2 of the anti-slip device main body 1 is inserted into the cutout 5 of the anti-slip device main body 1 so that it faces toward ．． The presser 6 and the spring plate 10 are fixed by a fixing member 14 to the surface of a concave portion 17 that passes through the fixing hole 11 and is provided on the contact surface side of the heel 15 .

In order to provide the anti-slip footwear sole according to the present invention with such a configuration, the anti-slip part 3 and the anti-slip part 4 are placed on the ground on the rear side of the heel 15, as shown in FIGS. 2 and 3. The anti-slip tool body 1 is fixed so as to protrude from the bottom surface of the footwear.

This fixation is performed by the protrusion 7 of the presser 6 and the stopper 8 of the presser 6.

In other words, the fixing force of the protrusion 7 of the presser 6 alone cannot prevent the anti-slip device main body 1 from slipping off due to external forces such as the road surface when walking. By fixing the protrusion 7
The fixing force caused by the fixing force of the stopper 8 and the fixing force of the stopper 8 are combined to become strong, and it is possible to prevent the anti-slip tool main body 1 from slipping out of the fixed position.

If you walk on a slippery road surface such as a frozen or snowy road while wearing footwear having the anti-slip footwear sole according to the present invention in such a state, the tips of the anti-slip part 3 and anti-slip part 4 will dig into the road surface, making it difficult to walk. This can prevent slipping in the front-rear direction and left-right direction.

If it is not necessary to provide an anti-slip effect when walking on a normal road surface, the anti-slip device main body 1 is turned upside down around the rotating shaft portion 2 as shown in FIG. The longitudinal anti-slip part 3 and the lateral anti-skid part 4 are stored in the storage part 18 of the heel 15.

In this case, the protrusion 7 of the presser 6 is used to fix it, but if the fixing force is weak, a stopper may be provided by bending the end of the presser 6 on the non-treadable side.

By storing and fixing the anti-slip tool main body 1 in the storage part 18 by turning it upside down, that is, the longitudinal anti-slip part 3 and the side anti-slip part 4 of the anti-slip main body 1 are stored in the storage part 18.
Since the anti-slip part 3 and the anti-skid part 4 are stored in the periphery of the convex part A and the mouth of the concave part, the non-slip part 3 and the anti-slip part 4 do not come into contact with the road surface when walking, so there is no discomfort and there is no damage to the road surface.

The rotation of the anti-slip tool main body 1 according to the present invention is carried out by the rotating shaft portion 2, but if the end of the rotating shaft portion 2 is in direct contact with the surface of the concave portion of the heel, the surface of the concave portion is likely to be damaged as the number of rotations increases. Therefore, by stacking the spring plate 10 between the presser 6 and the concave surface 17 as shown in FIG. The elastic force of the plate facilitates smoother fixing, making it possible to more stably fix the anti-slip device main body 1, and also to prevent damage to the surface of the concave portion 17.

Furthermore, due to the presence of the fixing plate 12 incorporated in the recess 16 provided inside the heel 15, unlike simply fixing the presser 6 and the spring plate 10 directly to the heel 15, the presser 6, the spring plate 10 Since the fixing plate 12 and the fixing plate 12 are fixed to the heel 15 by sandwiching the heel 15, the fixing plate 12 is securely fixed to the heel.

In addition, as shown in FIGS. 2 to 4, the convex part A of the storage part 18 is provided extending from the front side of the heel 15 to the non-stepping part side of the sole, so it serves as reinforcement for the non-stepping part, so it can be used when walking. The unstepped part on the back remains intact, making it easier to walk on.

In the non-slip footwear according to the present invention, the presser 6 is fixed together with the spring plate 10 to the contact surface side of the heel 15 by the fixing device 14, and the fixing plate 12 is fixed to the inner side of the heel 15. As shown in FIG. 5, if at least one or all of the fixing devices 14 are easily attached and removed, such as screws or bolts, the anti-slip portion 3 of the anti-slip device body 1 can be used.
Alternatively, when the anti-slip portion 4 is worn out and the anti-slip effect is reduced or lost, the anti-slip main body 1 can be easily replaced.

As detailed above, the anti-slip footwear sole according to the present invention has the anti-slip part 3 and the anti-skid part 4 facing the contact surface of the heel 15 when walking on a slippery road surface such as a frozen road surface or a snow-covered road surface. By placing the anti-slip device 1 on its side, it can exhibit an anti-slip effect in the front-rear direction and left-right direction when walking, and when walking on regular roads, indoor floors, etc., the anti-slip device body 1 can be placed upside down and stored. By storing it in the part 18, you can walk without any difference from a normal heel, and since the storing part 18 extends from the front side of the heel to the unstepped part of the bottom, you can feel less fatigue when walking. It has various excellent advantages, and further has the advantage that the anti-slip device main body 1 can be easily replaced when the anti-slip part 3 and the anti-skid part 4 become worn out, which increases its practical value. There is a big one.
