Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a footwear sole with a non-slip device having a structure in which the non-slip device can be set in a state of use or stored and can be selected as desired. be.

In the past, many proposals have been made regarding footwear soles suitable for walking on slippery surfaces such as frozen roads and snow-covered roads, but most of them have anti-slip devices in the soles of the footwear. Since it is buried and fixed, it has an effective anti-slip effect when walking on frozen or snowy roads, which is convenient.
When walking on paved roads or indoor floors, anti-slip devices not only damage the road or floor surface, but also have drawbacks such as being uncomfortable to wear when walking. Another inconvenience was that the anti-slip device could not be replaced if it wore out. In addition, in the case of footwear such as light mountain climbing shoes and hiking shoes, anti-slip devices are always fixed on the non-stepping part of the sole of the footwear, so it will not slip when walking on a flat surface or when going up or down stairs. It also has the disadvantage that the anti-slip device gets in the way and makes it difficult to ride on the road.

The present invention eliminates the various drawbacks of the conventional products described above, and the anti-slip device can be removed as needed.
To provide a footwear sole having a structure that allows storage.

In other words, anti-slip devices are installed to prevent slipping when walking on slippery surfaces such as frozen roads or snow-covered roads, or when climbing or hiking; The present invention relates to a footwear sole with a non-slip device which functions similarly to a normal footwear sole by retracting the non-slip device when walking on the floor.

The present invention relates to an improvement of the device disclosed in Japanese Utility Model Application Publication No. 161928/1983 by the same applicant, and has claws that exhibit an anti-slip effect in both the front and rear directions and the left and right directions when walking. Anti-slip devices are attached to the soles of the footwear, so when walking on slippery surfaces, the nails stick out and touch the ground, and when walking on regular roads or indoor floors, the anti-slip devices are attached.
An anti-slip device that can be rotated 180 degrees and housed in the sole of the footwear to prevent the nails from touching the ground, and further characterized in that the anti-slip device is attached in a replaceable manner. The company developed a new footwear sole.

Hereinafter, specific examples will be explained in detail with reference to the drawings.

Possible locations for attaching the anti-slip device include the heel portion and the non-stepping portion, so both cases will be explained.

(A) When attaching the anti-slip device to the heel part The drawings show one embodiment of the present invention.
Fig. 1 is a plan view of the anti-slip device, Fig. 2 is a side view, Fig. 3 is a plan view of the rotating device, Fig. 4 is a side view, and Fig. 5 is the rotating device attached to the anti-slip device. 6 is a side view, and FIG. 7 is a side sectional view of the heel of the sole of the footwear with the anti-slip device attached to the heel when anti-slip effect is required. FIG. 8 is a plan view of the state. 9 is a plan view of the heel part with the rotating tool raised;
The figure is a side sectional view of the anti-slip device stored in the heel portion when the anti-slip device is not needed.

In the figure, reference numeral 1 denotes a non-slip tool, and a claw 2 is provided on a part of its periphery, the tip of which is bent in a triangular shape with respect to the plane of the non-slip tool. A holding hole 4 is bored in the approximate center of the anti-slip tool 1, and a rotating tool 6
In order to effectively hold the shaft portion 7 of the bearing 3 and the rotating tool 6, a hook hole 5 is provided through which a protrusion 8 provided on the rotating tool 6 can pass. A shaft portion 7 is provided at one end of the rotating tool 6, and a protrusion 8 is formed on the rotating tool 6, which is inserted into the hook hole 5 of the anti-slip tool 1 to securely hold the rotating tool 6. There is. A fixing member 9 passes through the holding hole 4 of the anti-slip device 1 and holds the anti-slip device 1 in a concave portion 11 provided in the heel of the sole 10 of the footwear. 12 and 12' are recesses having a depth that allows the protrusion 8 provided in the heel recess 11 to be inserted through the hook hole 5;
13 is the contact surface of the heel. That is, as shown in FIGS. 5 and 6, the shaft portion 7 of the rotary tool 6 is attached to the bearing portion 3 so that the protrusion 8 can be passed through the hook hole 5 on the anti-slip device 1 for footwear soles according to the present invention. It is assembled so as to be supported at
It is rotatably held by a fixture 9 on the inner surface 11' of the concave portion 11 provided on the side.

Footwear sole 10 of the present invention comprising the above-described mechanism
In order to exhibit the anti-slip effect of the anti-slip device 1 attached to the heel, as shown in FIG. 8 through the hook hole 5 and further inserted into the recess 12, the rotating tool 6 is pushed down by the force of the spring of the bearing 3, and the surface of the shaft 7 of the rotating tool 6 is pushed down. is closely fixed to the anti-slip tool 1, and the anti-slip tool 1 no longer rotates. The protrusion 8 prevents the anti-slip tool 1 from rotating when the rotating tool 6 is placed in a depression 12 or 12' provided on the inner surface 11' of the concave portion 11 of the heel.
It is only necessary that the protrusion 8 is inserted and the anti-slip tool 1 is held firmly so that it does not rotate, so the hook hole 5 does not necessarily have to be provided in the anti-slip tool 1.

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 is attached to the sole of the footwear according to the present invention in such a state, the tips of the claws 2 may touch the ground contact surface of the footwear sole. Since it protrudes from 13, it seems to bite into the road surface, preventing slipping when walking.

When walking on a normal road surface, that is, when no anti-slip surface is required, as shown in FIG. Outside sushi No. 8
After setting up the rotating tool 6 as shown in the figure, while holding the rotating tool 6, insert the anti-slip tool 1 as shown by the arrow B in Figure 8.
Rotate 180 degrees and remove the heel concave part 1 as shown in Figure 9.
After retracting the claw 2 side into the 9th
By pulling down as shown by the arrow C in the figure, the restoring force of the spring force of the bearing part 3 presses down the shaft part 7, so that the rotating tool 6 and the anti-slip tool 1 come into close contact again and catch the protrusion 8. It is passed through the hole 5 and further inserted into the recess 12, so that the anti-slip tool 1 is fixed and does not rotate.
That is, the heel periphery of the footwear sole 10 is raised like a bank, and a lower convex recess 11 is formed on the inner side thereof. Therefore, the claw 2 of the anti-slip tool 1 is the ninth
As shown in the figure, since it does not protrude from the ground contact surface 13, it does not cause discomfort to the wearer and does not damage the road surface, floor surface, etc. That is, as shown in FIGS. 7 and 9, the inner surface 11' of the concave portion 11 provided on the side of the ground plane 13 of the heel that holds the anti-slip device 1 is in contact with the ground plane 13 on the rear side of the heel. The claw 2 provided on the anti-slip device 1 has a surface that is shallow and deep with respect to the ground contact surface 13 on the front side of the heel and slopes from the rear side to the front side.
Since the tip of the tip is parallel to the inner surface 11', if an anti-slip effect is required, the tip of the seventh
As shown in the figure, by firmly holding the claw 2 of the anti-slip tool 1 so as to be positioned on the rear side of the heel, the tip of the claw 2 will inevitably protrude above the ground surface.

When the anti-slip effect is not required, the anti-slip device 1 can be rotated 180 degrees and stored in the front side of the heel, that is, on the deeper side 11' of the recessed part 11, as shown in Fig. 9. Since the claws 2 are stored in the concave portion 11, the claws 2 do not protrude toward the ground surface 13, and therefore do not come into contact with the road surface.

When holding the anti-slip tool 1 on the inner surface 11' of the concave portion 11, if a fixing device 9 that is easy to attach and remove, such as a screw, bolt, or nut, is used, the claws 2 of the anti-slip tool 1 can be prevented from wearing out. This has the advantage that the anti-slip tool 1 can be easily replaced when the anti-slip effect is reduced or completely lost.

In addition, in order to prevent the inner surface 11' of the concave portion 11 from being worn out or becoming difficult to rotate due to the rotation of the anti-slip tool 1, the anti-slip tool 1 and the inner surface 1
An auxiliary plate made of a hard and wear-resistant material and having a smooth surface may be provided between the plate 1' and the plate 1'.

(B) Case of attaching an anti-slip device to the non-stepping part of the sole or heel of footwear Although an example of attaching the anti-slip device to the heel was explained in paragraph (A), the present invention is not necessarily limited to the above example. It also includes the case where it is attached across from the non-stepping part of the sole of the footwear to the heel part, and an example of such a case will be described below.

As shown in FIGS. 10 and 11, the anti-slip device 1 on which the rotating device 6 is supported is provided on the surface 14' of the non-stepping part 14 of the sole 10 of footwear and on the heel using a fixing device 9. It is attached on the surface 15' of the notched recess 15. In this case, it can be applied to light mountain climbing shoes, hiking shoes, etc. that require the anti-slip device 1 to be attached to the non-stepping part.

In order to exhibit the anti-slip effect, the anti-slip device 1 is held firmly in a state protruding from the surface of the footwear sole so that the claw 2 is in contact with the toe side of the footwear sole 10 of the non-stepping portion 14, as shown in FIG. let In such conditions, the anti-slip effect is fully demonstrated when climbing rocky areas such as mountain climbing.

If the anti-slip effect is not required, rotate the anti-slip tool 1 180 degrees while rotating the rotating tool 6 in an upright position, and insert the anti-slip tool into the recess 15 cut out on the non-stepping side of the heel. 1's claw 2 is retracted. Therefore, since the claw 2 is housed in the heel, there is no protruding part on the non-stepping part, so it has the advantage that it is easy to walk on normal road surfaces, indoor floors, etc.

The shape of the anti-slip device 1 according to the present invention may be any shape as long as it is easy to provide the claw 2, the bearing portion 3, and the hooking hole 5, and may be any suitable shape such as a polygon, circle, oval, semicircle, triangle, square, or rectangle. shape is used. Further, the shape of the claw 2 may be either a square shape or a square shape, as long as the tip thereof is pointed.

The shape of the hooking hole 5 and the depressions 12 and 12' may be any shape as long as the protrusion 8 is inserted and the anti-slip tool 1 is inserted into the protrusion 8 and can be held in place so as not to rotate. Good luck, hollow 12
The depth of 12' and 12' is not particularly limited as long as it can be maintained.

The bearing part 3 has a bent shape that presses down the shaft part 7, and when the rotating tool 6 is pulled up, it deforms temporarily, but it has a spring force and when the rotating tool 6 is pulled down, the bearing part 3 deforms temporarily. It is sufficient that the shape is such that it automatically restores itself with the force of a spring and presses down the shaft portion 7. Further, the bearing portion 3 may be formed by attaching a separately manufactured bearing portion 3 to the anti-slip tool 1, or may be formed by bending a part of the anti-slip tool 1. Furthermore, there are 5 hook holes, 8 protrusions, and 1 depression.
2, 12', the number of bearing parts 3, and the shaft part 7 are sufficient as long as they can firmly hold the anti-slip device 1 and are easy to rotate, so they only need to be provided in one or more places, and their positions are also limited. It's not a thing.

The present invention has the advantage that since the anti-slip tool 1 is protruded or retracted by touching only the rotary tool 6, there is almost no need to directly touch the claw 2, so there is no risk of injury to the hand. ing. Further, a separate knob may be provided to make it easier to grip the rotating tool 6. In order to prevent the rotating tool 6 from falling to the opposite side when raised, a stopper may be provided on the shaft portion 7 of the rotating tool 6 on the side opposite to the protrusion 8.

As described in detail above, the anti-slip footwear sole according to the present invention rotates the claws 2 to the rear side of the heel when walking on slippery surfaces such as frozen roads and snow-covered roads, so that the anti-slip footwear sole according to the present invention can be used in the forward and backward directions of walking. It is also possible to exhibit an anti-slip effect in both the front and rear directions. Furthermore, when walking on a normal road surface or an indoor floor surface, the anti-slip device 1 can be rotated half a turn and stored in the front side of the recessed part 11 of the heel, so that it has the advantage of being able to walk in exactly the same way as with a normal heel. Furthermore, it has the convenience that the anti-slip device 1 can be easily replaced when the claw 2 becomes worn out. It also has great practical value, as it can be used in light mountain climbing shoes and hiking shoes, which require anti-slip devices on the non-stepping parts of the soles.
