Description

[Detailed Description of the Invention] The present invention allows the user to set the anti-slip device in use as necessary, or store the anti-slip device in a recess provided in the sole of the footwear, which can be selected as desired. This relates to a footwear sole with a smooth structure and a non-slip device.

In the past, many proposals have been made regarding anti-slip devices suitable for walking on slippery surfaces such as frozen roads and snow-covered roads, but most of them have no anti-slip devices. Since it is embedded and fixed in the sole of the footwear in use, it has an effective anti-slip effect when walking on frozen or snowy roads, but it can be slippery when walking on paved roads or indoor floors. Not only do the fasteners damage the road or floor surface, but they also have drawbacks such as being uncomfortable to wear when walking. There was also the inconvenience that the anti-slip device could not be replaced if it wore out.

The present invention eliminates the various drawbacks of the conventional products described above, and makes it possible to make the anti-slip device protrude from the contact surface of the sole of the footwear or to store it in the recessed part of the heel of the sole of the footwear, as necessary. The present invention relates to a footwear sole with an anti-slip device that has a structure that allows for a slippery structure.

In other words, anti-slip devices are installed to prevent slipping when walking on slippery surfaces such as frozen roads or snow-covered roads. A footwear sole with an anti-slip device has been developed which allows the anti-slip device to be kept in a retracted state when the shoe is worn, allowing it to function in the same way as a regular footwear sole.

In the present invention, an anti-slip device having a claw that exhibits an anti-slip effect when walking is attached to the sole of the footwear, so when walking on a slippery road surface, the claw protrudes and makes contact with the ground. When walking on a surface, the anti-slip device can be retracted to store the nail in the sole of the footwear to prevent the nail from touching the ground, and the anti-slip device can be replaced and installed at will. To provide a footwear sole with an anti-slip device, which is also characterized in that it is possible to do this.

The present invention will be explained below with reference to the drawings.

The drawings show one embodiment of the present invention; FIG. 1 is a side sectional view of the anti-slip device attached to the sole of footwear when an anti-slip effect is required; FIG. 2 is a bottom view of the same; FIG. 3 is a side sectional view of the anti-slip device stored in the sole of the footwear when the anti-slip device is not needed, and FIG. 4 is an enlarged side sectional view of the movable piece holding portion of the anti-slip device.

In the figure, reference numeral 1 denotes a non-slip device, and a claw 2 is formed on a part of the periphery of the distal end side of a movable piece 3 forming the anti-slip device 1 and has a sharp tip bent with respect to the plane of the movable piece. A supporting mechanism for supporting the sole of the footwear is provided near the center of the movable piece 3, and a shaft 4 is provided on the base side of the movable piece 3, and the shaft 4 of the anti-slip device 1 and the holding piece 6 and the support part 7 are hinged. Reference numeral 5 denotes a rotary tool that is combined with the movable piece 3 of the anti-slip tool 1 to move the movable piece 3 of the anti-slip tool 1 up and down. As shown in FIG. 4, the rotating tool 5 is slidably fitted with a support rod 10 with a flange 11 whose head is embedded and fixed in the sole of the footwear, and a part of the support rod 10 is provided with a groove. Alternatively, a hole is provided and the rotating tool 5 is caulked to such an extent that it can rotate freely. Reference numeral 6 denotes a holding piece for holding the anti-slip device 1 on the sole of the footwear, and it is fixed to a recessed part 8 provided in the sole of the footwear. It is convenient because the anti-slip tool 1 can be replaced when it wears out. Reference numeral 7 indicates a support portion of the holding piece 6, and reference numeral 9 indicates a contact surface of the sole of the footwear.

That is, the anti-slip device 1 for footwear soles according to the present invention has the first
As shown in Fig. 2, the holding piece 6 of the anti-slip device 1 is fixed to a part of the recessed part 8 provided in the heel of the sole of the footwear, and the shaft 4 is held as a fulcrum by the support part 7 of the holding piece 6. It has a mechanism that can move the hinged movable piece 3 up and down by a combination of a support rod 10 embedded in a flange portion 11 and a rotating tool 5 fitted therein.

In order to exhibit the anti-slip effect of the anti-slip device 1 attached to the sole of the footwear of the present invention, which has the above-mentioned mechanism, the claw 2 provided on the movable piece 3 as shown in FIG. By rotating the rotary tool 5 so that it faces the ground plane 9 and the tips of the claws 2 protrude from the ground plane 9, the movable piece 3 is held approximately parallel to the ground with the shaft 4 as a fulcrum. be.

In such a state, when walking on a slippery road surface such as a frozen road surface or a snow-covered road surface while wearing footwear having the anti-slip device 1 attached to the footwear sole according to the present invention, the tips of the claws 2 may come into contact with the footwear sole. Since it protrudes from the ground 9, it bites into the road surface and can prevent slipping when walking.

On the other hand, when walking on a normal road surface, that is, when no anti-slip surface is required, by rotating the rotary tool 5 as shown in FIG. At the same time, the anti-slip device 1 is stored close to the inner surface of the concave portion 8 of the sole of the footwear. Therefore, the claw 2 provided on the movable piece 3 of the anti-slip device 1 does not protrude from the ground surface 9 as shown in FIG. It will not damage surfaces etc.

That is, as shown in FIGS. 1 and 3, by rotating the rotary tool 5 that holds the anti-slip tool 1, the movable piece 3 moves vertically about the shaft 4 to provide the anti-slip effect. In this case, the tip of the claw 2 is made to protrude from the ground surface 9 by holding the anti-slip tool 1 in the state shown in FIG. 1 and moving it toward the ground surface 9 and holding it there.

When the anti-slip effect is not required, the state shown in FIG. 3 is reached, and the rotating tool 5 is rotated to move the anti-slip tool 1 to the inner surface of the recess 8 in the sole of the footwear, and it slides into the recess 8. Since the stopper 1 is retracted, the claw 2 does not protrude toward the ground surface 9, so it does not come into contact with the road surface.

When fixing the holding piece 6 to the concave part 8 of the sole of the footwear, by using a fixing device that is easy to attach and remove, such as a screw, bolt, or nut, the anti-slip effect can be prevented even when the pawl 2 of the anti-slip device 1 is worn out. This is advantageous because the anti-slip device 1 can be easily replaced when the number of anti-slip devices decreases or disappears altogether.

The shape of the anti-slip tool 1 according to the present invention is not particularly limited as long as the claw 2, movable piece 3, and shaft 4 can be easily provided, and may be any suitable shape such as a polygon, semicircle, triangle, or square. can be used. Nail 2 again
The shape of 〓, 〓 is fine as long as the tip is pointed.
It can be used arbitrarily, such as the form or 〓 form.

The rotating tool 5 may have any structure as long as it can move the movable piece 3 of the anti-slip tool 1 up and down with the shaft 4 as a fulcrum by rotation, but in the present invention, as shown in FIG. Any device can be used as long as it can move the protrusion up and down by rotating it with a large screw or the like.

Further, the movable piece 3 may have any structure as long as it can be combined with the rotating tool 5 so that the claw 2 can easily move up and down when the rotating tool 5 is rotated. Further, the movable piece 3 may be made separately from the anti-slip device 1, or may be made integrally with it and can bend around the shaft 4 as a fulcrum.

The rotating tool 5 only needs to have its base fixed to the inner surface of the recessed part 8 provided in the heel of the sole of the footwear, and may also be provided with a retractable knob to facilitate rotation by grasping the hand. Alternatively, a groove or a hole may be provided in the head of the rotary tool 5 on the ground side, and another rotation assisting tool may be inserted into the groove or hole and rotated.

As detailed above, the anti-slip footwear sole according to the present invention exhibits an anti-slip effect by protruding the claws 2 from the ground surface 9 when walking on slippery surfaces such as frozen roads and snow-covered roads. On the other hand, when walking on a normal road surface or an indoor floor surface, by storing the anti-slip device 1 in the inner surface of the recessed part 8, there is an advantage that the user can walk in the same way as with the sole of normal footwear. Moreover, when the claw 2 becomes worn out, it can be easily replaced, so its utility value is extremely great.
