DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to prevent slippage by easily attaching to rubber boots or other shoes when working on slippery places such as wetlands, rough terrain, snowy roads, frozen grounds, etc., and work safely. The present invention relates to a non-slip device for shoes that can be used.

[0002]

2. Description of the Related Art A crampon has long been known as a non-slip device for shoes. Conventional crampons are mainly used to prevent slippage in frozen areas and mountainous areas, and basically use a strong metal member with claws formed with a string etc. for climbing shoes, caravan shoes, etc. It is fixed. Further, as disclosed in Japanese Utility Model Application Laid-Open No. 185907/1985, there is known a device in which a non-slip device having a non-slip surface of hard particles is attached to and detached from a shoe sole such as ordinary leather shoes.

[0003]

A conventional crampon has a hard and strong metal member having claws formed on a shoe sole, so that it can be used for mountain climbing shoes and caravan shoes having a somewhat strong shoe sole. Although it is used, it is not used by attaching it to rubber boots or work shoes with a relatively soft sole such as each work. However, mowing in wetlands, forests and other slopes can be very slippery and dangerous due to wet soil and grass on the soil surface.
It is desirable to stabilize the feet in order to improve work efficiency.

[0004] It is difficult to firmly attach a conventional metal crampon to rubber boots or shoes having a relatively soft sole such as every work, and even if it is fitted, a hard crampon bears on the foot. And cannot work comfortably. In addition, muddy water adheres to cloth or leather straps for attaching crampons, making it difficult to maintain a stable wearing state, or soil adheres to crampons to prevent slipping. May not be fully demonstrated. In view of the above-mentioned drawbacks of the prior art, the present invention can be easily attached to and detached from rubber boots or shoes having a relatively soft bottom such as work, and exhibits a more reliable anti-slip effect, and It is an object of the present invention to provide a shoe slipper which can safely carry out a mowing operation in a skid, or a slipper which can safely walk on snowy roads.

[0005]

In order to achieve the above object, the anti-slip device of the present invention comprises a toe bottom 1 on which a claw 8 is integrally mounted, a toe cover 2 for covering the upper surface of the toe bottom 1,
A waist belt portion 3 extending rearward from the rear end of the toe bottom 1 and capable of engaging with the waist portion of the shoe is integrally formed of a flexible material having elasticity.

[0006] The toe cover portion 2 has a right side belt 4 and a left side belt 5 continuous from the left and right sides of the toe bottom 1 and a wide toe belt 6 continuous from the tip of the toe bottom 1 continuous on the upper surface. It is preferable to form a cutout 7 in which the toe of the shoe engages. Also, waist belt
3 is a flat belt-shaped belt right side 9 extending from the left and right sides of the rear end of the toe bottom 1 to the rear in the same plane as the toe bottom 1.
When the belt left side 10 is folded back to the upper surface, and formed by the belt right side 9 and a flat belt waist 11 continuous with the belt left side 10, the belt right side 9 and the belt left side 10 adhere to the side of the shoe, In addition, the belt waist 11 can be worn in a state where the belt waist 11 is in close contact with the waist of the shoe. Furthermore, if the right upper belt 12 and the left upper belt 13 are made to protrude on both left and right sides of the rear end of the lower end of the toe bottom 1 so that the right upper belt 12 and the left upper belt 13 protrude, the anti-slip device is provided by the right upper belt 12 and the left upper belt 13. It can be more securely attached to shoes.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a shoe anti-slip device according to the present invention. 1 is a perspective view of the entire non-slip device, FIG. 2 is a plan view, and FIG. 3 is a cross-sectional view taken along line II-II of FIG. FIG. 4 is a bottom view, and FIG. 5 is a central longitudinal sectional view of the whole.

The slip stopper according to the present invention is integrally formed of a relatively flexible material having a certain degree of elasticity, such as a rubber material such as natural rubber or synthetic rubber, or a soft synthetic resin material. The integrally formed non-slip device includes a flat toe bottom 1 located on the front half of the shoe, that is, the bottom of the toe, a toe cover 2 for covering the upper surface of the toe of the shoe, and a waist belt for hanging over the waist of the shoe. And 3. The planar toe bottom 1 is a main component of a non-slip device, and is integrally provided with a non-slip claw 8 as shown in FIG. In order to mount the claw 8 integrally with the toe bottom 1, use a claw 8 having a flat seat 8 a such as a disk, insert-mold the seat 8 a into the tongue cover 2, and lower the claw downward. It is good to make it protrude toward. In the illustrated embodiment, the insert portion 14 of the seat 8a is made thick so that one nail is securely held.

In the illustrated example, as a result of increasing the thickness of only the insert portion 14 of the seat 8a, a circular protruding portion appears on the surface.
The whole bottom 1 may be formed to a certain thickness with a certain thickness. In this case, the sense of incongruity when worn on the shoes is eliminated, and the whole is formed to be thick, so that a stable feeling can be obtained. Further, in the illustrated example, five independent claws 8, 8 are insert-molded on the toe bottom 1, but the form of the claws 8 is not limited to this. Although not shown, for example, a nail body formed by cutting and raising a plurality of nails 8 from a single steel plate like a crampon is used, and the flat plate portion of the nail body is insert-molded into a flexible material such as rubber. Alternatively, the toe bottom 1 having the claw 8 projecting downward may be formed. In this case, while the toe bottom 1 itself becomes strong,
With a flexible material such as rubber, a soft hit state can be realized.

The toe bottom 1 is provided with a toe cover 2 which covers the upper surface of the toe bottom 1 continuously from the left, right and front outer peripheries. The tongue cover portion 2 may completely cover the whole like the tongue portion of shoes or slippers, but in the illustrated example, the right side belt 4 and the left side belt 5 continuous from both left and right sides of the toe bottom 1 and A toe belt 6 continuous from the tip of the toe bottom 1 is formed continuously on the upper surface.

When the toe portion of a shoe such as rubber boots is inserted into the tongue cover portion 2 which is completely covered like the toe portion of a shoe or a slipper, the material of the slip stopper and the material of the shoe are changed. Depending on the combination, a phenomenon occurs in which the resistance is large and the creaking is difficult to mount. Further, in such a case, it is difficult to correct a displacement or the like after mounting. On the other hand, when the hook cover is formed in a belt shape as in the illustrated embodiment, it can be easily attached to shoes. In addition, the belt-shaped toe cover that is worn acts to tighten the toe part of the shoe and produces moderate frictional resistance on a relatively large surface, and is firmly attached so that it does not shift during work or walking. You. In addition, if the toe belt 6 is formed wide and the notch 7 with which the toe of the shoe engages is formed, the tip of the shoe is inserted into the notch 7 to shift the position of the shoe relative to the toe bottom 1. Can be prevented.

A waist belt portion 3 is provided at the rear end of the toe bottom portion 1 so as to extend rearward and be able to be locked to the waist portion of the shoe. The waist belt portion 3 is formed by folding a flat belt-shaped belt right side portion 9 and a belt left side portion 10 extending rearward from the left and right sides of the rear end portion of the planar tongue bottom 1 on the same plane as the tongue bottom 1 on the upper surface, It is formed by a flat belt waist 11 which is continuous with the belt right side 9 and the belt left side 10. However, the specific form of the waist belt portion 3 may be, for example, a string shape having a circular cross section.

As shown in FIG. 7, in the shoe anti-slip device according to the present invention, a toe portion is inserted between the toe bottom portion 1 and the toe cover 2 while wearing shoes such as rubber boots A, The waist belt portion 3 is used by being wound around the waist portion of rubber boots A. The length of the waist belt portion 3 is at least a length that does not loosen when the shoe antiskid is worn, and is preferably a length that can be used in a state where the waist belt portion 3 is stretched to an extent that an appropriate pulling force is generated. . Thereby, it can be attached by a simple operation such as putting on a slip stopper on a foot wearing shoes.

As described above, the waist belt portion 3 may have a string shape having a circular cross section or the like. However, as shown in the illustrated example, the waist belt portion 3 is formed into a flat belt-like belt with a predetermined width, and is folded back to be continuous at the belt waist portion 11 to withstand a greater tensile force, and
The belt is in contact with the surface of the shoe on a wide surface, so it is not twisted and does not shift due to moderate frictional resistance. It is possible to do.

In order to stabilize the attached shoe anti-slip device so that it does not fall off the shoe, the toe bottom 1
The instep belt is formed in advance. In the illustrated upper belt, the right upper belt 12 and the left upper belt 13 are made to protrude on both left and right sides of the rear end of the toe bottom 1 so as to be continuous with the toe bottom 1. And
The hook-and-loop fasteners 15 and 16 are provided at the tip portions of the right upper belt 12 and the left upper belt 13, respectively. As a result, after attaching the shoe anti-slip device in the same manner as wearing shoes, the right upper belt
Tighten the upper part with 12 and left upper belt 13 and hook and loop fastener
Lock at 15,16. The locking between the right upper belt 12 and the left upper belt 13 can be stopped by any locking means such as a buckle other than the hook-and-loop fastener. In addition, the right upper belt 12 and the left upper belt 13 are a single upper belt that is continuous in an arch shape, and the length, belt width and thickness so that the upper part of the shoe can always be tightened with a moderate force when worn. May be set.

Since the toe bottom 1 of the shoe anti-slip device of the illustrated embodiment is formed symmetrically, two identical ones are used as a set. However, the flat shape of the toe bottom may be formed into a last that fits the shape of a shoe. In this case, two symmetrical shapes are used as one set. Also, the shoe anti-slip device of the illustrated embodiment shows the whole integrally molded with a relatively thin rubber material, but it is not always necessary that all of the parts are integrally molded, It may be formed integrally by joining means such as adhesion and sewing. In that case, it is desirable to select a material suitable for the characteristics of each part and to consider so that a sufficient bonding strength is obtained. However, when the whole is integrally molded with a synthetic rubber material or the like, it is not necessary to consider the joining strength and the like, and it is possible to provide a relatively high-quality product at a low cost.

The tip of the claw 8 in the illustrated embodiment is not sharp. When used for the purpose of preventing slipping when working on soft ground, the claw 8 can sufficiently perform its function even if it is not sharp. However,
In the case where the claw 8 is used for the purpose of preventing slippage on an icy road, a greater anti-slip effect can be exhibited if the claw 8 is sharpened.

In addition, in the illustrated embodiment, as shown in FIG. 4, a large number of small anti-slip projections 17, 17 are formed on the surface of the toe bottom 1 so that the effect of the anti-slip may be supplementarily enhanced depending on the situation. ing. Also, the waist of the waist belt 3
A knob 18 is protruded from 11 and the antislip device for shoes according to the present invention can be easily attached and detached by gripping the knob 18 with fingers.

[0019]

According to the anti-slip device for shoes of the present invention according to the first aspect, the anti-slip device of the present invention can be easily attached to shoes of relatively soft material such as rubber boots and used in wetlands, rough terrain, snowy roads, frozen lands and the like. When working in a slippery place, it is possible to prevent slipping and to proceed safely. In addition, it is possible to provide the anti-slip device at a low cost by forming the whole anti-slip device into a very simple structure.

According to the second aspect of the present invention, it is possible to avoid a situation in which the material of the shoe and the material of the anti-slip device have a large frictional resistance and are squeaky and difficult to wear.
By inserting and engaging the toes of the shoe into the notches in the toe belt, the anti-slip and the shoe can be securely mounted in the most stable position.

According to the third aspect of the present invention, the mounted shoe anti-slip device can be firmly held by the flat waist belt. At this time, the flat waist belt is in a stable state where it makes continuous surface contact with the side of the shoe and the waist without causing torsion. And work can be done.

According to the fourth aspect of the present invention, by fixing the upper belt to the upper part of the shoe, the anti-slip device for shoes can be more securely attached to the shoe, and the anti-slip device is inadvertently applied to the shoe. It is possible to prevent a situation in which the user gets off.
