Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip device and a set of anti-slip devices for shoes, which are used by pedestrians wearing shoes for the purpose of preventing slip when walking on snowy or frozen roads.

[0002]

2. Description of the Related Art Conventionally, specific examples of non-slip devices for shoes include those described in, for example, Japanese Utility Model Publication No. 2-1045 and Japanese Utility Model Registration No. 3015810.
As shown in FIG. 24 of the present application, the shoe anti-slip device C1 described in the former Japanese Utility Model Publication No. 2-1045 discloses an annular band-shaped portion 80 to be hooked on the toe 9a of the shoe 9, Annular band-shaped portion 81 hooked on the heel portion 9b of the
An intermediate portion 82 that connects the two belt-shaped portions 80 and 81 is provided.
Is provided.

[0003] The latter utility model registration No. 3015810
No. 2, the anti-slip device for shoes C2 described in
As shown in FIG. 5 and FIG. 26, a front bottom 85 having a front cover 84 and a heel bottom 87 having a rear cover 86 are interconnected via two strips 88a, 88b. A fastening band 89 having a buckle 89a is provided between the front cover 85 and the rear cover 86, and a plurality of non-slip projections 83a are provided on the front bottom portion 85 and the heel bottom portion 87.

[0004] Each of the above shoe slip stoppers C1 and C2 can be attached to and detached from shoes. When the user walks while wearing the shoe, the protrusions 83 or the protrusions 83a can be made to enter the road surface, and an anti-slip effect when walking on a snowy road surface or a frozen road surface can be obtained.

[0005]

However, the above-mentioned conventional anti-skid devices C1 and C2 have the following disadvantages.

That is, the above-mentioned conventional shoe anti-slip device C1 merely has a configuration in which a projection 83 is provided on substantially the entire surface of an intermediate portion 82 connecting two belt-shaped portions 80 and 81 to each other. It is not a configuration in which elasticity is positively provided. Even if the intermediate portion 82 is made of rubber, the intermediate portion 82 does not provide sufficient elasticity by itself because it contacts the road surface. For this reason, the shoe anti-slip device C1
When the user wears the shoe 9 on the shoe 9 and walks, the shoe slip stopper C1 is easily detached from the shoe 9.

More specifically, when walking with the shoe anti-slip device C1 attached to the shoe 9, the protrusions 83 of the intermediate portion 82 come into contact with the ground and cut into the shoe. Tool C
1, a force is generated in which the intermediate portion 82 moves relative to the shoe 9 in various directions of front, rear, left and right. When such a force is generated, in the shoe anti-skid device C1, the force is not efficiently absorbed and alleviated in the intermediate portion 82, and the force directly acts on the two band portions 80 and 81. . For this reason, in the shoe anti-slip device C1, for example, when a force is generated to move the intermediate portion 82 in the heel direction of the shoe 9 (the direction of the arrow Na in FIG. 24), the band portion 81 is loosened in the same direction. Becomes On the other hand, the above-mentioned band-shaped portion 81 is
Unlike 0, it is not hung on the upper surface of the shoe 9 or the like, but is only hung on the shoe 9 along the outer peripheral side surface of the heel 9b. Therefore, in the shoe anti-slip device C1, the force in the direction of the arrow Na is generated in the intermediate portion 82 and the band portion 81 is slightly loosened in the same direction, and the band portion 81 is moved from the heel portion 9b. There was a risk that the battery would easily come off. In this case, it is not possible to reliably prevent slippage during walking. In addition, it is necessary to frequently re-attach the non-slip device C1 for shoes, which has caused inconvenience.

On the other hand, the above-mentioned conventional shoe anti-slip device C
In 2, since the fastening band 89 having the buckle 89a can be appropriately fastened, it is possible to prevent the shoe from being accidentally detached from the shoe as compared with the shoe anti-slip device C1 described above. However, in the shoe anti-skid device C2, the fastening band 89 having the buckle 89a is provided.
Also, since the front cover 85 and the heel bottom 87 are provided with the front cover 84 and the rear cover 86 connected to each other, the number of parts of the shoe anti-slip device is large, and the configuration is very large. There has been a problem that the manufacturing cost is complicated and the manufacturing cost is high.

In the shoe anti-slip device C2, as shown in FIG. 26, the front bottom portion 85 and the heel bottom portion 87 are basically connected via two strip-shaped portions 88a and 88b. They are just interconnected. In such a configuration,
Since the front edge 87c of the heel bottom 87 is formed in a wide shape having the dimension L, the front end 87c is liable to be caught by the uneven portion of the road surface during walking. When such catching occurs, the entire heel bottom 87 generates a force to move in the direction of the arrow Nb, and the strips 88a and 88b are loosened. For this reason, also in the above-mentioned shoe anti-slip device C2, similarly to the former shoe anti-slip device C1, the band-like portions 88a,
88b is easily loosened, and the heel bottom 87
However, there is a possibility that the rubber is easily displaced with respect to the heel of the shoe and easily comes off the shoe.

[0010] Further, in the shoe anti-slip device C2, for example, when a contraction force Ta is generated in one of the band portions 88b,
One end 8 of the heel bottom portion 87 in the width direction is formed by the
7a receives a tensile force in the same direction. Then, a moment M is generated in the entire heel bottom portion 87, and the other band portion 88a has
A force Tb is generated in a direction in which the belt-shaped portion 88a is elongated to cause slack. Accordingly, in the shoe anti-skid device C2, the belt-like portion 88b is apt to be loosened even by such a phenomenon, and the heel bottom 87 is easily displaced with respect to the heel of the shoe. There was a risk that it would come off.

Conventionally, other non-slip devices for shoes have been described in, for example, Japanese Utility Model Application Laid-Open No. 63-135804.
The basic configuration thereof is the same as that of the shoe anti-slip device C1 described above with reference to FIG. 24, and two annular belt-shaped portions to be hooked on the toe portion and the heel portion of the shoe, respectively. It has an intermediate portion that connects the belt-shaped portions to each other, and has a configuration in which a projection for preventing slippage is provided in this intermediate portion, and when it is worn on a shoe and walks, it has a problem that it is easily detached from the shoe. .

The present invention has been made in view of such circumstances, and it is possible to minimize the complexity of the structure of the shoe anti-slip device and to prevent the shoe anti-slip device from being used during use. Can be easily removed from the shoe,
It is an object of the present invention to enhance the non-slip function of a shoe anti-slip device and to make it easy to handle.

[0013]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

That is, according to a first aspect of the present invention, there is provided a non-slip device for shoes. The shoe anti-slip device includes a first hook portion for hooking the shoe to the toe portion,
A second hooking portion for hooking the heel portion of the shoe;
A non-slip device for a shoe, comprising: an intermediate portion connecting the hook portion and the second hook portion; and a non-slip means provided at the intermediate portion. A plurality of elastically expandable and contractible portions extending in the longitudinal direction of the intermediate portion are provided, and the plurality of expandable and contractible portions are formed of two lines located on both side edges of the intermediate portion in the width direction. It is characterized in that there are at least one or more second expandable portions located in the width direction intermediate portion between the first expandable portion and the two first expandable portions.

[0015] The anti-slip device for shoes provided by the present invention has a first hooking portion hooked on the toe portion of the shoe and a second hooking portion hooked on the heel portion of the shoe. ,
An intermediate portion having a non-slip means is used by arranging it on the bottom surface of the shoe sole. In this use, when a force is generated to move the intermediate portion relative to the sole of the shoe, for example, in the front-rear direction of the shoe, the plurality of elastic portions provided in the intermediate portion are actively contracted. Or can be extended. If the plurality of extending / contracting portions of the intermediate portion extend or contract in this manner, the amount of extension / contraction of the first engaging portion and the second engaging portion can be reduced accordingly, and these first and second engaging portions can be reduced accordingly. It is possible to prevent the hooking portion and the second hooking portion from loosening largely and coming off the shoe. More specifically, in the present invention, when a force is generated to move the intermediate portion relative to the sole of the shoe in the front-rear direction, the force can be efficiently absorbed and moderated by the intermediate portion itself. Differently, it is possible to suppress the above-mentioned force from directly acting on the first hooking portion and the second hooking portion. For this reason, in the present invention, for example, even if the second hooking portion is merely hooked along the outer peripheral side surface of the heel portion of the shoe, as in the conventional case, the second hooking portion may be attached to the second hooking portion. It is possible to prevent loosening and easy detachment from the heel of the shoe.

In particular, in the present invention, the plurality of stretchable portions provided at the intermediate portion include not only the two first stretchable portions located at both side edges in the width direction of the intermediate portion but also the first stretchable portion. In addition to this, since it also has the second elastic portion located in the widthwise intermediate portion between these two first elastic portions, the elasticity of the intermediate portion is good due to the large number of elastic portions. In addition to the above, the following excellent effects can be obtained.

That is, when, for example, a force for contracting one of the two first expandable portions is generated, the other first expandable portion is extended. In this case, the second expandable portion exerts a resistance, thereby preventing the other first expandable portion from being greatly expanded. The second elastic portion acts so as to reduce the force generated in each of the two first elastic portions or the difference in the amount of expansion and contraction. Therefore,
Even in the case where a force for moving the intermediate portion in a direction deviated from the sole is generated, the force is deviated from the intermediate portion to the first hooking portion or the second hooking portion. The transmission is alleviated, and it is possible to prevent the first and second hook portions from loosening largely in one direction.

Further, if the intermediate portion is provided not only with the two first elastic portions but also with the second elastic portion, the intermediate portion may be caught on the uneven portion of the road surface during walking. It is also possible to make it difficult. More specifically, for example, if one large hole is formed in the middle portion to provide only two first elastic portions, the inner peripheral edge of the hole extending in the width direction of the middle portion is formed. Becomes large, and the inner peripheral edge portion is liable to be caught by the uneven portion of the road surface. However, as in the present invention, the first of Article 2
If the second elastic portion is provided between the elastic portions, the size of the inner peripheral edge portion of the hole that causes the bump on the uneven portion of the road surface can be reduced by the width of the second elastic portion. The possibility that the intermediate portion is caught on the road surface can be reduced.

As described above, according to the present invention, it is possible to reduce the possibility that the first and second hook portions are largely loosened in one direction or the middle portion is hooked on the road surface. . As a result, in the present invention, it is possible to more reliably prevent the shoe anti-slip device from coming off the shoe, increase the reliability of the anti-slip device, and improve the handling thereof. .

In a preferred embodiment of the present invention, the non-slip means includes a first region of the intermediate portion which is close to the first locking portion and a second region which is close to the second locking portion.
And the plurality of elastic portions are provided between the first region and the second region.

According to such a configuration, the anti-slip means provided in the first area is arranged at a position near the toe of the shoe, and the anti-slip means provided in the second area is provided on the heel of the shoe. It can be arranged, and the slip is prevented on both the toe side and the heel side of the shoe, which is preferable for enhancing the anti-slip effect. In addition, since the plurality of extending and contracting portions are provided between the first region and the second region, for example, even if the first region generates a force to move relative to the shoe, the force is reduced. The extension to the second area is eliminated as it is, and the anti-slip means provided in the second area can be fixed at a desired fixed position. Therefore, there is also an advantage that the parts of the intermediate portion do not frequently move relative to the shoe, the sense of unity between the shoe and the shoe anti-slip device is improved, and the comfort of the shoe can be improved. can get.

In another preferred embodiment of the present invention,
Each of the first hooking portion, the second hooking portion, and the intermediate portion is integrally and continuously provided on the basis of one stretchable rubber sheet material.

According to such a configuration, not only the plurality of elastic portions provided at the intermediate portion, but also other portions of the intermediate portion, and the first and second hooking portions are provided. Can also be made to have elasticity, and it is possible to more reliably prevent the anti-slip device for shoes from being unjustly detached from the shoe. In addition, since the first engaging portion, the second engaging portion, and the intermediate portion are integrally connected, the connection strength of these portions can be increased, and the service life thereof can be extended. It is also possible to do.

In another preferred embodiment of the present invention,
The first hook and the second hook are provided with a first through-hole and a second through-hole at both ends of the rubber sheet so that both ends of the rubber sheet are connected to each other. A plurality of third through-holes, which are annular portions, and in which the plurality of extending and contracting portions are arranged in the middle portion of the rubber sheet material at intervals in the width direction of the middle portion. Is formed.

According to such a configuration, the first hook portion,
Since each of the second hooking portion and the plurality of stretchable portions at the intermediate portion can be formed only by providing a through hole in one rubber sheet material, the manufacture thereof can be performed very easily. Therefore, it is advantageous in reducing the manufacturing cost.

In another preferred embodiment of the present invention,
Overlay portions are provided at both ends in the width direction of the peripheral portion of the first through-hole and / or the second through-hole.

According to such a configuration, it is possible to increase the durability of the anti-slip device for shoes and prolong the service life thereof. In other words, when the shoe anti-slip device is attached to a desired shoe, the first hooking portion or the second hooking portion is maintained in a state of being appropriately extended in the longitudinal direction (front-back direction) of the shoe. However, when the first hooking portion or the second hooking portion is extended in this way, the tensile stress is concentrated on both ends in the width direction of the first through hole or the second through hole. Works. Accordingly, damage such as cracking of the rubber sheet material is likely to occur at both ends in the width direction of the peripheral portion of the through hole. However, since the portion is provided with a built-up portion and reinforced, such damage can be appropriately prevented, and the durability can be increased.

In another preferred embodiment of the present invention,
The anti-slip means is a protrusion projecting from the surface of the intermediate portion, and the protrusion has a high hardness in a temperature region below a predetermined temperature and a low hardness in a temperature region higher than the predetermined temperature. Material.

According to such a configuration, the hardness of the protrusion changes depending on the temperature condition, and for example, the following effects can be obtained. That is, since the protrusion has a high hardness in a temperature region equal to or lower than a predetermined temperature, for example, in a temperature region below the freezing point, the hardness of the protrusion can be increased, and the protrusion can function as a high hardness spike. . On the other hand, since the protrusion has a low hardness in a temperature range higher than the predetermined temperature, the protrusion can be prevented from functioning as a spike in a temperature range higher than the freezing point. More specifically, when the shoe anti-slip device is used by attaching it to shoes, when walking on a snow-covered road surface or a frozen road surface, the protrusion functions appropriately as a spike to obtain a slip prevention effect. On the other hand, when walking in other places such as a hotel lobby, the protrusions should not function as spikes,
The floor surface can be prevented from being damaged. As a result, it is not necessary for the user to frequently attach and detach the antiskid device for shoes according to the environment of the place where the user walks, and the convenience in using the antiskid device can be further improved.

In another preferred embodiment of the present invention,
The non-slip means is a spike supported by a seat, and the seat is made of a material having a high hardness in a temperature region equal to or lower than a predetermined temperature and a low hardness in a temperature region higher than the predetermined temperature. is there.

According to such a configuration, the hardness of the seat supporting the spike changes depending on the temperature condition. For example, when walking on a snow-covered road or a frozen road under a temperature below freezing, the seat is raised. The hardness is set so that the spikes supported by the seat portion can be appropriately bitten into a snow-covered road surface or a frozen road surface. On the other hand, under the condition of a temperature higher than the freezing point, by lowering the hardness of the seat, it is possible to prevent the spike from digging into the road surface by, for example, immersing the spike inside the seat. it can. Therefore, in the present embodiment, similarly to the above-described embodiment, the spike function is sufficiently exerted only when walking on a snowy road surface or a frozen road surface, while spikes are generated when walking in other places. It can be set so that it does not function, and it is possible to eliminate the trouble of frequently attaching and detaching the shoe anti-slip device to and from the shoe.

According to a second aspect of the present invention, a non-slip set is provided. The non-slip set includes a non-slip device for shoes provided by the first aspect of the present invention, and the intermediate portion of the non-slip device for shoes when the non-slip device is attached to a shoe. And a band that can be wound around the shoe so as to press it.

In the shoe anti-slip set provided by the present invention, as described above, the shoe anti-slip itself has an effect of not easily coming off the shoe easily, and the shoe anti-slip is provided by a band. By setting the middle part of the tool so as to press it against the sole of the shoe, it is possible to more reliably prevent the shoe slip stopper from coming off the shoe. Therefore, the present invention is not limited to the case where the user walks slowly on a snowy road or the like, but may be suitable for a case where he / she rushes by running fast.

The first engaging portion 1 is a portion for engaging the toe portion of the shoe, and the first engaging portion 1 is attached to one end 5a of the rubber sheet material 5 having a predetermined contour in the longitudinal direction. By providing the through holes 10, an annular strip 11 is formed at one end 5a of the rubber sheet material. Since the belt-like portion 11 is formed by a part of the rubber sheet material 5, it can expand and contract by itself. The first through-hole 10 has a size that allows the toes of a desired shoe to be inserted. Overlay portions 12, 12 are provided at both ends in the width direction of the peripheral portion of the first through hole 10. As shown in FIG. 4, these overlaid portions 12, 12 are portions having a greater thickness than other portions of the rubber sheet material 5.

The second hooking portion 2 is a portion for hooking on the heel portion of the shoe. A second through hole 20 is provided at the other end 5b of the rubber sheet material 5 in the longitudinal direction. The other end 5b of the rubber sheet material 5 has
Is formed. The strip 21
Can be expanded and contracted by itself as in the case of the belt-shaped portion 11. The strip 21 is provided with a projection 23 as appropriate. The protruding piece 23 is a part used when the band-shaped part 21 is gripped by a finger when the band-shaped part 21 is attached to and detached from the heel of the shoe. As shown in FIG. 5, overlaid portions 22, 22 are provided at both ends in the width direction of the peripheral portion of the second through hole 20. These overlaid portions 22, 22 are the same as the overlaid portions 12, 12 for the first through hole 10.

The intermediate portion 3 is a portion arranged to face the sole of the shoe when the shoe anti-slip device A is mounted on the shoe. The intermediate portion 3 includes a first region 30A approaching the first hook portion 1 and a second region 30A approaching the second hook portion 2.
There is a region 30B, and a plurality of protrusions 4 are provided in the first region 30A and the second region 30B. As shown in FIG. 2, a portion of each of the first region 30 </ b> A and the second region 30 </ b> B is formed to be thicker than other portions of the antiskid device A for shoes. According to such a configuration, a portion provided with the protrusion 4 can be provided with a suitable cushioning property, which is preferable, but the present invention is not limited thereto. In the present invention, the region 30
The entirety of A and 30B may have substantially the same thickness as the other parts. In the present embodiment, as well shown in FIGS. 2 and 3, on the opposite surface of the first region 30A,
A plurality of convex portions 31 are provided. The plurality of convex portions 31 are convenient for bringing the intermediate portion 3 into close contact with the shoe sole when the shoe antiskid device A is attached to the shoe. However, the invention of the present application is not limited to this, and it is not always necessary to provide the above-mentioned convex portion 31.

The plurality of elastic portions 30a to 30c are, specifically, two first elastic portions 30a and 30b located on both side edges in the width direction of the intermediate portion 3, and these two elastic portions 30a to 30c.
And one second elastic portion 30c located in the widthwise intermediate portion between the first elastic portions 30a and 30b. These extendable portions 30a to 30c are formed by arranging two third through holes 32, 32 in the intermediate portion 3 with a space therebetween in the width direction of the intermediate portion 3. Is a belt-like shape extending in the longitudinal direction. The plurality of elastic portions 30
a to 30c are provided between the first region 30A and the second region 30B, respectively.

The plurality of protrusions 4 are provided in the first region 30.
An appropriate number is provided for each of A and the second region 30B. As shown in FIG. 6, for example, the cross-sectional structure of each of the projections 4 is such that a small projection 41 is protruded from the center of a substantially disk-shaped seat 40 having a certain thickness. The entirety of the projections 4 is formed of a material having a high hardness in a low temperature range below a predetermined temperature and a low hardness in a temperature range higher than the predetermined temperature. As a specific example of the material, polynorbornene is plasticized with an aromatic oil, and the secondary point transfer is, for example, 0 ° C. ± 5 ° C.
Is used. Polynorbornene is obtained by adding ethylene to cyclopentadiene, obtaining Noribonene by a Diels-Adalda reaction, and further performing ring-opening polymerization. Additives for increasing the thermal conductivity are also mixed into the polymer. As the additive, for example, metal oxide fine particles, resin, and glass fine particles are applied. In addition, an appropriate amount of carbon particles or the like for increasing the strength of the projections 4 is mixed with the polymer.

The protrusion 4 has a hardness of about 65 ° C. in a temperature range of + 5 ° C. to + 10 ° C., and has a much higher hardness in the temperature range of 0 ° C. or higher than the rubber sheet material 5. Hardness is not high. On the other hand, in a temperature range of 0 ° C. or less, the hardness is sharply increased to about 95 °, and the hardness is significantly higher than that of the rubber sheet material 5. Such hardness characteristics can be obtained by adjusting the mixing ratio of the polymer and the additive. Specifically, for example, the volume ratio may be 30 parts of metal oxide fine particles, 20 parts of resin, and 20 parts of glass particles with respect to 100 parts of the polymer.

Each of the projections 4 and the rubber sheet material 5 are
For example, they are formed simultaneously and are integrally joined by thermocompression bonding. This is because the material for forming the protrusions 4 is filled in advance in the cavity of the mold for forming the rubber sheet material 5 so that the rubber sheet material 5 can be formed. This can be achieved by simultaneously molding the rubber sheet material 5 and the projections 4 and applying pressure while heating the material of each member during the molding. According to such a joining method, since each of the projections 4 and the rubber sheet material 5 can be integrated, it is possible to reduce the possibility that the projections 4 are accidentally dropped from the rubber sheet material 5. it can.

The outer shape of the shoe anti-slip device A is determined by assuming the specific shape of the shoe to be worn, and the shoe anti-slip device A is used for the right shoe or the left shoe. It may be formed for use. Alternatively, the shoe anti-slip device A may be formed in a shape that can be used for both the left shoe and the right shoe. The arrangement of the plurality of protrusions 4 is appropriately determined depending on whether or not the shoe antiskid device A is configured for the right shoe, the left shoe, or both.

Next, an example of use of the slip stopper A having the above configuration will be described.

As shown in FIGS. 7 and 8, when the shoe anti-slip device A is mounted on the shoe 9, the first through hole 1
0, the toe 9a of the shoe 9 is inserted, and the first hook 1 is hooked on the toe 9a of the shoe 9. On the other hand, the second hook 2
The heel portion 9b of the shoe 9 is partially inserted into the second through hole 20 by extending the entire rubber sheet material 5 by, for example, picking the protruding portion 23 with a finger. 9b. By such an operation, the whole of the intermediate portion 3 can be arranged to face the bottom of the shoe 9, and the first region 30
The plurality of protrusions 4 provided in A can be arranged at a position near the toe 9a of the shoe 9, and the protrusions 4 of the second area 30B can be arranged at a position near the heel of the shoe 9.

As described above, when the antiskid device A for shoes is mounted on the shoe 9, not only the belt-shaped portions 11 and 21 are moderately tensioned, but also the intermediate portion 3 has a total of three stretchable portions 30a to 30a.
30c is also appropriately tensioned, so that the elasticity can be exerted in substantially the entire region other than the region where the protrusions 4 are provided. Therefore, the shoe antiskid device A can be fitted to the shoe 9 because the entire shoe antiskid device A exhibits elasticity.

When the wearer of the shoe anti-slip device A walks, a force is generated to move the intermediate portion 3 relative to the shoe 9 in various directions of front, rear, left and right. However, this power
First telescopic parts 30a, 30b and second telescopic part 30
c is absorbed and relaxed by the expansion / contraction action of c, and the above-mentioned force is suppressed from directly affecting the first hooking section 1 and the second hooking section 2. Further, as a force acting on the intermediate portion 3, as shown in FIG. 8, for example, as a result of the contraction force T1 being generated in one of the first elastic portions 30a, this force is applied to the other first elastic portion 30b. May be generated. In such a case, originally, the portion of the second hook portion 2 close to the other first telescopic portion 30b tends to be loosened. However,
In the shoe anti-slip device A, the second elastic portion 30c
Exerts a resistance force, and the second elastic portion 30c exerts a force T3 for pulling a substantially central portion in the width direction of the second engaging portion 2 toward the intermediate portion 3, so that the other first elastic portion Part 3
The generation of a large slack in a portion near 0b is suppressed. Therefore, it is possible to appropriately prevent the second hooking portion 2 from accidentally coming off the heel portion 9b of the shoe 9.

Further, in the shoe anti-slip device A, the two third through holes 32, 32 are formed in the intermediate portion 3 and the two first extendable portions 30a, 30b are provided. The front edges 39, 39 of the second region 30B (the rear edge of the inner periphery of the third through-hole 32) are stepped walls with respect to the road surface. However, a second elastic portion 30c is provided between these two front edge portions 39, 39, and the width dimension La of each of the front edge portions 39, 39 is the same as that of the second elastic portion 30c. Is substantially reduced by the width dimension of. Therefore, when the wearer of the shoe non-slip device A walks, it is possible to reduce the possibility that the front edge portions 39 and 39 may be caught on the uneven portion of the road surface, which is convenient.

On the other hand, each of the projections 4 of the shoe antiskid device A
The hardness changes depending on temperature conditions, and when walking on a snow-covered road surface or a frozen road surface, the road surface is cooled by the road surface, and the temperature increases to 0 ° C. or lower, thereby increasing the hardness. Therefore, when walking on a snowy road surface or the like, each projection 4 can be appropriately functioned as a hard spike, and an excellent anti-slip effect can be obtained. On the other hand, when the wearer of the shoe anti-slip device A walks on a relatively warm place other than the snow-covered road surface or the frozen road surface, the temperature of each of the protrusions 4 becomes a temperature exceeding 0 ° C. , Its hardness decreases. Therefore, even if the user wears the shoe anti-slip device A and walks, for example, in a hotel lobby or a store, the projections 4 do not damage the floor surface. As a result, when the wearer of the shoe antiskid device A moves from, for example, a frozen road surface to another place, there is no need to attach and detach the shoe antiskid device A from the shoe 9 each time, which is convenient. Becomes

At the time of attaching and detaching the shoe anti-slip device A, the respective band-shaped portions 11 and 21 of the first engaging portion 1 and the second engaging portion 2 are repeatedly expanded and contracted. The stress caused by the expansion and contraction of the rubber is concentrated on both ends in the width direction of the peripheral portion of each of the through hole 10 and the second through hole 20. However, these portions are provided with the built-up portions 12, 22 and are reinforced, so that they can sufficiently withstand these stresses. Therefore, it is possible to prevent the shoe antiskid device A from being easily damaged by repeated use or long-term use of the shoe antiskid device A.

FIG. 9 is a plan view showing an example of a band B which is a component of the anti-slip set according to the present invention.
FIG. 10 is a front view thereof.

The band B is composed of a tape-shaped band body 6 having a fixed length, and a pair of hook-and-loop fasteners 60a, 60a provided at both longitudinal ends of the band body 6, respectively.
0b. The above band body 6
Is made of, for example, synthetic rubber, has flexibility, and is expandable and contractible in its longitudinal direction. The pair of hook-and-loop fasteners 60a and 60b are detachable from each other. For example, as shown in FIG. 11, when the band body 6 is deformed into a substantially arc shape, the pair of hook-and-loop fasteners 6a and 60b are used.
0a and 60b can be joined to each other.

The band B is used, for example, as shown in FIG. That is, in the state where the band B is mounted on the shoe 9 with the shoe non-slip device A attached thereto,
The shoe 9 is wound around the shoe 9 from the outside of the anti-slip device A for shoes. In this case, it is preferable that the band B is set so that the plurality of elastic portions 30a to 30c of the antiskid device A for shoes are pressed against the bottom of the shoe 9. With this setting, the band B allows the shoe anti-slip device A to more closely adhere to the shoe 9. In addition, a stronger tension can be applied to each of the plurality of extending / contracting portions 30a to 30c.
Is more reliably prevented from becoming loose from the shoe 9 due to loosening. Therefore, it can be suitable for use such as jogging on a snowy road.

Since the band B uses the hook-and-loop fasteners 60a and 60b as means for making both end portions detachable, the band B can be easily attached to and detached from the shoe 9.
By changing these joining positions, the advantage that the degree of tension of the band B can be easily adjusted can be obtained.
However, the present invention is not limited to this. In the present invention, for example, a pair of detachable hooks or buckles may be used instead of the surface fasteners 60a and 60b. Further, the shape of the band may be a complete ring shape such as a rubber band. Further, in the case where a buckle is used, the degree of tightening can be adjusted by the buckle, so that the band does not necessarily need to be formed of a stretchable elastic member.

FIGS. 13 and 14 are cross-sectional views of a main part showing another example of the anti-slip means applied to the anti-slip device for shoes according to the present invention. In the configuration shown in these figures, the anti-slip projection 4A provided on the surface of the intermediate portion 3 includes a seat 42 having an appropriate thickness and a metal spike 43 supported by the seat 42. It is comprised including. The spike 43 is buried in the seat 42 so that its tip protrudes outward from the seat 42.
The seat portion 42 is made of the same material as the material of the protrusion 4 of the anti-slip device A for shoes described above, and has a high hardness in a temperature region equal to or lower than a predetermined temperature, and has a higher temperature than the predetermined temperature. Also, the hardness becomes low in a high temperature range. As the specific material, a polymer in which polynorbornene is plasticized with an aromatic oil and the secondary transition point is adjusted to, for example, a range of 0 ° C. ± 5 ° C. is used as in the case of the protrusions 4.

According to such a configuration, when walking on a snow-covered road surface, a frozen road surface, or the like, the seat portion 42 is cooled to increase its hardness and to hold the spike 43 firmly. . Therefore, even when the spike 43 comes into contact with a frozen road surface or the like, the spike 4
3 can be surely cut into the road surface,
An appropriate anti-slip effect can be obtained. On the other hand, when walking on a relatively warm place other than a snow-covered road surface or a frozen road surface, the temperature of the seat portion 42 becomes higher than 0 ° C., and its hardness decreases. Therefore, for example, when walking in a hotel lobby or the like, as shown in FIG. 14, when the pressing force F acts on the spike 43, the pressing force F causes the seat 42 to elastically deform, and the spike 43 Seat 4
2 will be immersed. As a result, the above spike 4
3 makes it possible to avoid unduly damaging the floor surface. For this reason, even when the above-mentioned protrusion 4A is used, the trouble of frequently attaching and detaching the shoe anti-slip device from the shoe can be eliminated.

FIG. 15 is a plan view of an essential part showing another example of the non-slip means provided in the anti-slip device for shoes according to the present invention. FIG. 16 is a sectional view taken along line X5-X5 of FIG.

And a plurality of protrusions 45 arranged concentrically so as to surround the protrusions 44. Protrusion 4
4 is set to a dimension higher than the other plurality of protrusions 45. In addition, each of the plurality of protrusions 45 is preferably a seat 42 shown in FIGS.
Also, similarly to the material of the seat portion 40 shown in FIG. 6, the hardness changes depending on the temperature condition.

According to such a configuration, when walking on a snow-covered road surface, the protrusions 44 at the center can be deeply inserted into the snow-covered road surface, and a plurality of protrusions located around the periphery can be inserted. 45 can assist the biting. Therefore, the protrusions 44, 45
An excellent anti-slip function can be obtained without having to form the tip of the horn so sharply, and it is possible to reduce the risk of unduly damaging a general floor surface.

FIG. 17 is a perspective view showing another example of the anti-slip means provided in the anti-slip device for shoes according to the present invention. The spike member 4C shown in FIG.
For example, a projection 47 having a pyramid shape such as a triangular pyramid shape or a conical shape is provided on the surface of the surface 6. The material of the seat portion 46 and the projection 47 preferably has a hardness that changes according to temperature conditions. By joining the spike member 4C having the above configuration to the intermediate portion 3 by thermocompression bonding or the like, the above-described projections 4, 4A, 4B can also be formed.
Similarly to the above, an appropriate slip prevention effect can be obtained.
