Description

[Detailed description of the invention] The present invention can prevent slipping and falling when walking on slippery roads such as frozen roads or snow-covered roads, and can also prevent people from falling when walking on normal roads or floors inside houses. In particular, the present invention relates to a non-slip device having a structure that allows the non-slip device to be slid and then turned over and stored in a recessed portion of the sole of footwear.

In the past, many proposals have been made for walking on slippery surfaces such as frozen roads and snow-covered roads, but most of them have a structure in which anti-slip devices are embedded in the sole of the footwear. In addition, there are anti-slip fittings for shoe soles disclosed in Japanese Unexamined Patent Application Publication No. 48-27854 and Japanese Utility Model Application No. 49-13148, etc., but in the case of the former, it is difficult to use on frozen roads or This is convenient because the anti-slip effect is fully demonstrated when walking on snow-covered roads, but when walking on normal roads or indoor floors, the sharp tip of the anti-slip part may be on the floor. It has the disadvantage that it can damage the floor surface because it comes into contact with it in a way that it seems to pierce the floor surface. In addition, in the case of the one disclosed in the latter publication, when walking on frozen or snow-covered roads, the anti-slip metal fittings attached to the soles of the shoes are triggered to exert an anti-slip effect, which requires an anti-slip effect. When not in use, the anti-slip metal fittings are stored at the tip of the heel, so it is convenient to use, but while it has an anti-slip effect in the front and back directions when walking, it does not work in the lateral direction. has no anti-slip effect. Another disadvantage is that if the anti-slip fittings become damaged or worn out, they cannot be replaced.

The present invention solves the above-mentioned drawbacks of the conventional products, and the anti-slip effect in the longitudinal and lateral directions when walking is achieved 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 serves as a non-slip part that can be used in both the front and back as well as the lateral directions.

When walking on a slippery road surface, the anti-slip device of the present invention has the structure described above, and when walking on a slippery road surface, the anti-slip part is placed opposite the ground surface, and the sharp part at the tip of the anti-slip part is pushed into the ice or snow. On the other hand, when walking on normal roads or indoor floors, the anti-slip side of the anti-slip tool should be tilted at right angles to the guide, and then the movement axis of the anti-slip tool should be used as a guide. Slide it to the other end wall side of the gap between it and the back surface of the recess, then tilt it further at right angles in the same direction as before, that is, 180 degrees from the beginning, and position the anti-slip tool on the same plane as the guide. This relates to a non-slip device which is attached so that the entire non-slip device can be stored in a recess provided in the sole of footwear.

In the present invention, one side of the anti-slip tool 1 is made of a flat metal plate having an appropriate shape and has a cutout 5 cut out in the center, and the base 2
There is an L-shaped moving shaft 4 that points inward to each other on both sides of the base 2, and a non-slip portion 3 is attached to the edge of the anti-slip device 1 from one side facing the base 2 to both side edges of the non-slip device 1. The tip of the anti-slip part 3 is pointed in a triangular shape, and is supported by two parallel guides 6 that hold the movement axis 4 of the anti-slip tool 1. The moving shaft 4 can be slid along the created gap 9, and guide end walls 7 are provided at both ends of the guide 6.
A guide base 8 is further provided, and the moving shaft 4 is passed through a gap 9 created by the guide 6 to prevent the slip stopper 1 from falling off.
As a result, the moving shaft 4 can rotate at the position of the gap 9 and the guide end wall 7, and the non-slip part 3 of the anti-slip tool 1 can be placed facing up or facing down. This made it possible. As a result, the anti-slip device 1 can be stored in the recess provided on the ground-contact side of the sole of the footwear,
The structure is such that the anti-slip part 3 can be projected from the bottom of the footwear and can be changed freely.

In this case, the movable shaft 4 attached to the end of the base 2 can be either a completely fixed rivet or a removable screw, bolt, or nut.

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

The figures show one embodiment of the anti-slip device according to the present invention, and FIG. 1 is a perspective view of the anti-slip device, and FIG.
Figure 3 is a perspective view of the guide, Figure 3 is a perspective view of the combination of the anti-slip device and guide, and Figure 4 is a side cross-section illustrating how the anti-slip device is attached to the sole of footwear when anti-slip is required. Figure 5 is a side sectional view of the anti-slip device being stored inside the sole of the footwear when the anti-slip device is no longer needed, and Figure 6 is a side sectional view of the anti-slip device being stored inside the sole of the footwear when the anti-slip device is no longer needed. The side cross-sectional view and FIGS. 7 and 8 show perspective views of other embodiments of the anti-slip device.

In the figure, 1 is a non-slip device, with a base 2 on one side.
L-shaped moving shafts 4 facing inward to each other at both ends of the base 2
, and anti-slip portions 3 are provided on the side facing the base 2 and on both side edges thereof. In addition, a cutout 5 is provided approximately in the center of the anti-slip tool 1.
is cut out into an appropriate shape. Reference numeral 6 denotes a guide, and guide end walls 7 are provided at both ends of the guide, and a guide base 8 is provided so that the guide 6 can be easily held.
is provided. That is, in the anti-slip device according to the present invention, two guides 6 are arranged parallel to each other in a width that allows the moving shaft 4 of the anti-slip device 1 to move, and the guide base 8 of the guide 6 is brought into contact with the concave portion 12 of the sole 11 of the footwear. In other words, the moving shaft 4 is inserted into the gap 9 created between the guide 6 and the guide end wall 7, and the footwear sole 1 is
A stopper 10 is provided on a footwear sole 11 such that the moving shaft 4 of the anti-slip tool 1 is attached to either one of the guide end walls 7 so that the anti-slip part 3 faces the ground surface on the rear side of the stopper 10. It is fixed to a concave portion 12 provided on the ground surface side of the footwear sole 11 so as to be in contact with the edge 5a of the cutout portion 5.

In order to exhibit an anti-slip effect using the anti-slip device of the present invention having the above-described structure, it is necessary to place the anti-slip part 3 on the rear side of the footwear sole 11 so that it faces the ground surface as shown in FIG. to hold the anti-slip tool 1.

Of course, the tip of the anti-slip part 3 should be fixed together with the anti-slip device 1 in the concave part 12 of the footwear sole 11 so that the tip of the anti-slip part 3 protrudes from the ground plane 13, and the top surface of the guide 7 can fit inside the sole 11 of the footwear. be.

The anti-slip device 1 is held by the concave portion 12 of the sole 11 of the footwear.
The cutout part 5 is held by a stopper 10 provided in a protruding manner so as to be hooked onto the edge 5a of the cutout part 5. That is, as shown in FIGS. 3 and 4, by bringing the edge 5a of the cutout 5 into contact with the stopper 10 at two or more locations, the stopper 10 is firmly held and the holding position of the anti-slip device 1 is prevented from shifting during wear. It can be prevented. When walking on a frozen or snowy road surface wearing footwear in which the anti-slip device according to the present invention is fixed and held in the concave portion 12 of the footwear sole 11 in such a state, the tip of the anti-slip portion 3 will dig into the road surface. Therefore, 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 on the side facing the base 2 and along both side edges is that if it is provided at only one location, the anti-slip effect will only be effective in a specific direction; This is because by providing more than one location, the anti-slip effect can be achieved in any direction as seen from FIGS. 1 and 7.

When the anti-slip effect is not required when walking on a normal road surface, as shown in FIG. Slide the shaft 4 to the opposite side as shown by arrow B along the gap 9 created between the slide 6 and the inner surface of the recessed part 12, and move it to the position of the guide end wall 7 on the opposite side. Starting from the end wall 7, the anti-slip part 3 side is the footwear sole 1.
It is possible to prevent the anti-slip device 1 from wobbling by folding it down into the recessed part 12 of the anti-slip device 1 and storing it as shown in FIG. By knocking down the anti-slip device 1 and storing and holding the anti-slip device 1 in the concave portion of the footwear sole 11, the non-slip portion 3 is moved into the concave portion 12.
Since the anti-slip part 3 does not touch the road surface when walking, there is no discomfort, and the anti-slip part 3 does not touch the road surface when walking.
Do not damage the floor surface.

The moving shafts 4 provided at both ends of the base 2 of the anti-slip tool 1 are not integrated as shown in FIG. As shown in FIG. 4 or FIG. 6, the moving shaft 4 is held in a bent state relative to the base 2. If the moving shaft 4 is integrally fixed to both ends of the base 2 as shown in FIG. The moving shaft 4 is inserted into the holder to hold the anti-slip tool 1. Two moving shafts 4 may be provided at both ends of the base 2, with their tips facing inward, or the two ends may be connected and integrated as shown in FIG. Further, the base portion 2 and the moving shaft 4 may be integrated as shown in FIG. The moving shaft 4 may be completely fixed to the base 2 with rivets or the like, or may be removably attached with screws, bolts, nuts, etc. A removable type is more convenient in consideration of replacing the anti-slip part 3 with a new one if it becomes worn out or damaged.

When raising the non-slip part 3, there is a risk of injury to fingers as the tip of the non-slip part 3 is sharp, and if you try to raise the non-slip part 3 while wearing gloves, you may not be able to grasp it sufficiently. There is no inconvenience. Therefore, as a countermeasure, the anti-slip tool base 2 of the anti-slip part 3
By providing a knob 14 on the opposite side as shown in FIG. 7, the above-mentioned raising operation can be facilitated. Of course, the anti-slip device 1 is bent on the same plane as the anti-slip device 1 or diagonally so that it does not protrude from the ground surface of the sole of the footwear when the anti-slip device 1 is held.

The shape of the stopper 10 is the same as the shape of the edge 5a of the cutout part 5 of the anti-slip tool 1, and if the upper side is shaped like a flap, it is easier to hold the anti-slip tool 1 and it is stronger. Alternatively, it may be embedded and fixed in the inner surface of the concave portion 12 of the sole 11 of the footwear. stopper 1
It goes without saying that the height of the cutout 5 of the anti-slip device 1 may be such that it does not easily slip out, and preferably does not protrude from the ground contact surface of the sole of the footwear. Further, the stopper 10 can be formed by providing a convex body made of the same material as the footwear sole and having the same shape as the cutout 5 on the inner surface of the concave portion 12 of the footwear sole 11.

The shape of the anti-slip tool 1 is rectangular, triangular, semicircular,
Any shape such as a horseshoe may be used, and the anti-slip portion 3
The anti-slip device 1 may also be provided on either the outer peripheral edge or the cutout edge, or both edges. The shape of the cutout 5 can be freely selected from rectangular, triangular, circular, semicircular, etc.

When the guide base 8 is fixed in the recess 12 of the footwear sole 11, the guide 6 is connected to the inner surface of the recess 12.
Guide end walls 7 are provided at both ends of the guide 6, which can provide a gap 9 between the inner surface of the guide 6 and the inner surface of the guide 6 to allow the moving shaft 4 to move easily. A single parallel guide 6 may also be used instead. In addition, the guide base 8 is connected to the footwear sole 11.
may be embedded and fixed in the inner surface of the concave portion 12,
It may be removably attached using screws or the like.

By fixing a wear-resistant material to the inner surface of the recess 12 of the footwear sole 11 that the moving shaft 4 contacts, it is possible to prevent the inner surface of the recess 12 of the footwear sole 11 from being damaged due to movement of the moving shaft 4.

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 when walking on a slippery road surface such as a frozen road surface or a snow-covered road surface, the anti-slip part 3 is directed toward the ground surface. By placing the anti-slip device 1, it is possible to not only exert the anti-slip effect in the front and back directions and lateral directions when walking, but also to prevent slipping when walking on normal roads or indoor floors.
By tilting it 90 degrees, sliding it to the other guide end wall, and then pulling it down about 90 degrees in the same direction to store the anti-slip device 1 in the concave part 12 of the sole 11, it becomes a normal footwear sole. It has the advantage of being able to walk in the same way as walking. Also guide 6
It goes without saying that the anti-slip device 1 does not wobble due to the stopper 10 and the stopper 10, but the two may be integrally connected.

The product of the present invention has the advantage that it can be attached to any part of a footwear sole, and in the case of a footwear sole with a heel, it can be attached even within the heel by providing a concave part in the heel.
