Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a non-slip sole used for fishing and freezing roads.

[0002]

2. Description of the Related Art In fishing, since a fishing rod moves on a slippery surf, footwear that does not slip as much as possible is used for safety. This is because if you slide on the beach, you will be in a very dangerous state. Shoes have been developed that have a special non-slip ground contact. Currently, commercially available shoes for fishing use a felt for a grounded sole. A felt is a collection of innumerable fibers entwined in a three-dimensional manner. Compared with rubber or the like, the felt grounding bottom can move on the surf in a relatively non-slip state on the shore. However, the felt becomes slippery when seaweed or moss is caught between the fibers. Also, the felt is
There is also a drawback that the fine fibers are worn and the durability is reduced.

In order to overcome this drawback, non-slip shoe soles have been developed as described in the following publications. Japanese Utility Model Publication No. 1-126101 Japanese Utility Model Publication No. 63-191905 Japanese Utility Model Publication No. 4-4803 Japanese Patent Application Laid-Open No. 10-42905

[0004]

The shoe sole described in the publication of the invention has metal spikes arranged in the felt. The grounded bottom of this structure prevents the slip by causing the spike to bite into the crack of the rock or the like. Therefore, it is possible to move on the uneven surf without slipping. However, it has a drawback that it is very slippery on a monolith without unevenness. Further, footwear with fixed spikes becomes uncomfortable when the sole is softened, because the spikes push the sole of the foot locally and feel pain. It is necessary to harden the bottom so that the spikes do not make them uncomfortable. However, a shoe with a hard sole has less sole deformation during walking, which makes it difficult to walk and cannot provide comfortable wear. Also, the bottom cannot contact the rock over a wide area, and it is not possible to grip by gripping many spikes in the recess of the rock.

The above publication describes a shoe sole in which fibers and an abrasive are mixed and rolled with an adhesive such as phenol to be solidified into a water-permeable plate. Since this shoe sole has an abrasive added, it contacts the surface of the shore and prevents slipping. However, since the shoe sole of this structure is also solidified in a plate shape, it is difficult to bring a large number of abrasives into contact with a rock on a large area, and since it is rolled and solidified, it is considerably heavy. is there.

[0006] In the publication, a thermoplastic elastic polymer such as natural rubber or urethane which is foamed to 300% or less is added to 10
A shoe sole incorporating short fibers of mm or less is described. The sole can be foamed to make it lightweight. However, since this shoe sole has fibers protruding to the surface of the sole and exposes bubbles of foam to the surface to increase the coefficient of friction, it is hard and the frictional force against the slippery surf is small. , Can not be used safely enough on the beach. In addition, it is necessary to manufacture a unique structure in which fibers are embedded in a foamed thermoplastic elastic polymer, which increases the manufacturing cost. Raw material cost of foamed synthetic resin is high, and moreover,
This is because it takes time to foam and mold.

The publication describes a shoe sole obtained by impregnating a fiber laminate assembly such as a nonwoven fabric in which crimped or curled fibers are laminated with rubber or resin. Like the felt, the sole of this structure is made of fibers to prevent slipping, so
If seaweed or moss is caught between the fibers, it will easily slip. In particular, since the fibers are impregnated with rubber or the like, there are fewer voids between the fibers as compared with felt, and there are drawbacks that seagrass and moss are easily clogged.

The present inventor, for the purpose of eliminating these drawbacks of the sole, is a synthetic material which is flexible enough to elastically deform when stepped on a non-woven fabric in which high hardness particles are attached to fibers. We have developed a shoe sole embedded in resin foam. Since this shoe sole has an abrasive material attached to the non-woven fiber, it has a feature that it can be caught on the surface of a slippery surf and extremely slippery. However, since the shoe sole having this structure uses the foamed synthetic resin, it has a drawback that the manufacturing cost is increased and the expected life, for example, the life that can be used for surf fishing for 10 days or more cannot be realized.

The present invention was developed with the object of solving this drawback. An important object of the present invention is to provide an ideal non-slip shoe sole that can be moved extremely safely without slipping on a slippery shore while reducing the manufacturing cost, and can also realize excellent durability, and a manufacturing method thereof. To provide.

However, the following examples exemplify a non-slip sole and a manufacturing method thereof for embodying the technical idea of the present invention, and the present invention specifies the sole and the manufacturing method as follows. do not do.

Further, in this specification, in order to facilitate understanding of the claims, the numbers corresponding to the members shown in the embodiments are referred to as "claims column" and "to solve the problems." It is added to the members shown in "Means column". However, the members shown in the claims are not limited to the members of the embodiment.

FIG. 1 shows a shoe having a non-slip sole according to an embodiment of the present invention. The shoe sole of the present invention includes all types of fishing shoes used for rock fishing and river fishing, mountain shoes, ski shoes, rubber boots, work shoes, sports shoes, sandals, etc., which require non-slip. Applicable to footwear.

As for the shoe sole, as shown in FIG. 1, the grounding sole 7 is fixed to the insole 4 of the shoe, or as shown in FIGS. 2 to 4, the grounding sole 7 is detachably attached so that it can be replaced. I am wearing it. As shown in FIGS. 1 to 6, the grounding bottom 7 has an outer shape substantially equal to that of the insole 4, and is attached to the bottom surface of the insole 4. The ground contact bottom 7 has high hardness particles 2 attached to the surface of the non-woven fiber or high hardness particles 2 on both the surface of the fiber and the binder, or high hardness particles on the binder, in order to enhance the anti-slip effect. 2 is attached.

As shown in FIG. 2, the grounding bottom 7 which can be attached to and detached from the insole 4 has a felt 8 laminated on the upper surface thereof and adhered thereto.
The felt 8 is adhered to the entire surface of the ground bottom 7. A velcro tape 9 (registered trademark) is adhered to the bottom surface of the insole 4 that connects the grounding bottoms 7. Velcro 9 (registered trademark)
Has a myriad of hook fibers for hooking the fibers of the felt 8 protruding from the bottom surface. The grounded bottom 7 is connected to the insole 4 via a velcro tape 9 (registered trademark). The grounding bottom 7 of this structure can be easily attached to and detached from the insole 4. Further, there is a feature that the displacement of the ground contact bottom 7 can be surely prevented in a state of being connected to the insole contact 4.

As shown in FIGS. 3 and 4, the detachable grounding bottom 7 may be provided with a flange 5 on the upper surface and connected to the insole 4 by the flange 5. The grounding bottom 7 in this figure has the flange 5 protruding forward and backward. The flange 5 is fitted into the attachment / detachment groove 6 provided in the insole 4 of the shoe. The flange 5 is put in the attachment / detachment groove 6, and the ground bottom 7 is attached to the inner bottom 4. The shoe shown in FIG. 5 has a removable groove 6 on the bottom surface of the insole 4 in the front and back.
Is provided. Although not shown, the attachment / detachment groove may be provided on the entire circumference of the insole. The insole having a detachable groove on the entire circumference connects a grounded bottom having a flange on the periphery.

The flange 5 is provided by adhering a flexible plate member 10, for example, a rubber plate, to the upper surface of the grounding bottom 7. The plate member 10 has a flange 5 at a portion protruding from the outer periphery of the ground contact bottom 7.

The grounding bottom 7 reinforces the nonwoven fabric fibers by binding them with a binder. However, the shoe sole of the present invention is not one in which the binder is filled without gaps between the fibers. Innumerable voids are provided between the non-woven fabric fibers to cure the binder. Further, the shoe sole of the present invention is not the one obtained by foaming and hardening the binder. A binder is applied to a non-woven fabric, the non-woven fabric is pressed thinly to squeeze out excess binder, and then the non-woven fabric is thickly restored by the restoring force of the non-woven fabric.

The restorative force of the non-woven fabric creates a number of voids between the fibers, and the binder is cured in this state. The porosity, in other words, the ratio of the voids formed between the nonwoven fabric fibers to the entire volume is adjusted by the difference between the volume when the nonwoven fabric is pressed thinly and the volume when the nonwoven fabric is restored thick. For example, when the non-woven fabric is restored to twice the pressed thickness of the non-woven fabric and the binder is cured, the porosity becomes half of the total volume, that is, about 50%. In addition, when the non-woven fabric is restored to three times the pressed thickness and the binder is cured, the porosity is 2 / of the total volume.
3 or about 67%. The porosity provided between the non-woven fabric fibers can be adjusted by the ratio of the thickness when the binder is applied and pressed and the thickness when restored, and the porosity is increased by increasing the thickness when restored to the pressed thickness. Can be a lot.

The non-woven fabric 1 is obtained by assembling fibers in a three-dimensionally non-directional manner and bonding them to a predetermined thickness. The fibers are bonded at their intersections with an adhesive or by welding, or Instead of binding, they are bound by a binder that is applied later. As the fibers of the non-woven fabric 1, synthetic fibers such as nylon and polyester, or natural fibers such as palm fibers and hemp are used. Fibers such as synthetic fibers and hemp are three-dimensionally crimped or zigzag-shaped so that they are easily entangled. The zigzag shape is, for example, a shape obtained by bending a fiber into a triangular wave, a rectangular wave, and a sine wave. Since the palm fiber has a three-dimensional crimped shape, it is not necessary to artificially process it into such a shape. The fibers that are easily entangled can be aggregated in a three-dimensional direction.

The non-woven fabric 1 is thinly crushed when a liquid binder is applied and pressed and pressed, but it is restored when the pressed state is completely released or the pressing force is reduced in the uncured state of the binder. Is. When the fibers of the non-woven fabric 1 are made thicker, the restoring force becomes stronger. Non-woven fabric 1
Is pressed and then restored in a state where the binder is applied, innumerable fine voids are provided between the fibers, and the binder is cured in this state.

The non-woven fabric has a thickness of about 150 denier when the fibers are synthetic fibers. However, the shoe sole of the present invention does not specify the thickness of the synthetic fiber of the non-woven fabric to be about 150 denier. The reason for this is that when a liquid binder that has a low viscosity in the uncured state is used, the non-woven fabric of fine fibers is sufficiently restored, and sufficient voids are formed between the fibers. Therefore, for the fibers of the non-woven fabric, for example,
10 to 300 denier, preferably 50 to 200 denier, and more preferably 100 to 200 denier can be used. As for the natural fiber, the same thickness as that of the synthetic fiber is used.

Further, it is most suitable that the synthetic fiber has an uneven surface. In order to make the surface uneven, for example, an adhesive is applied to the surface of the fiber in a non-uniform manner, or the fiber is partially formed into a shape having a different thickness.

The ground contact bottom 7 has the high hardness particles 2 attached to the surface of the non-woven fiber or to the binder. The high hardness particles 2 are adhered to the fiber surface or the binder via an adhesive. Abrasive particles such as alumina and silicon carbide are suitable for the high hardness particles 2. The size of the high hardness particles 2 is
The optimum value is set depending on the use, but for example, 120
A material having a mesh size of 400 mesh is most suitable because it increases the friction coefficient in general applications. However, as the high hardness particles 2, particles having a mesh size of 60 to 1200 can be used depending on the application. As the adhesive agent for adhering the high hardness particles 2, an adhesive agent for adhering the intersections of the non-woven fabric fibers can be used together.
However, the adhesive agent for bonding the high hardness particles 2 and the adhesive material for bonding the non-woven fabric fibers may be different from each other.

[0030]

EXAMPLES Example 1 The grounding bottom 7 shown in FIG. 6 is manufactured as follows. 200 mesh of alumina as high hardness particles 2 is attached to the fibers of the non-woven fabric 1 as an abrasive. The abrasive is

An uncured liquid binder is applied to the nonwoven fabric 1. Urethane resin is used for the binder. To the binder, 5% by weight of 200 mesh alumina is added as an abrasive. The nonwoven fabric 1 coated with the binder is pressed to a thickness of 3 to 4 mm to squeeze out and remove excess binder, and further, the binder is attached to the fiber surface and the fiber intersection.

After pressing and squeezing out the binder, the pressed state is released while the binder is uncured. In this state, the nonwoven fabric 1 is restored by its own restoring force and becomes thick. In this state, the nonwoven fabric 1 is restored to a thickness of about 8 mm. When the binder was cured in this state, the ground contact bottom 7 having a specific gravity of 0.6 was obtained.

The nonwoven fabric 1 coated with the binder is pressed to a thickness of 3 to 4 mm to squeeze out and remove excess binder, and further, the binder is attached to the fiber surface and the fiber intersection.

After pressing and squeezing out the binder, the pressed state is released while the binder is in an uncured state. In this state, the nonwoven fabric 1 is restored by its own restoring force and becomes thick. In this state, the nonwoven fabric 1 is restored to a thickness of about 8 mm. When the binder was cured in this state, the ground contact bottom 7 having a specific gravity of 0.6 was obtained. Cut the binder-cured non-woven fabric 1 into a foot mold,

The paste-like adhesive is added and kneaded, and this is sprayed and adhered to the nonwoven fabric 1. As the non-woven fabric 1, a polyester fiber having a thickness of about 10 mm and 150 denier when not pressed is used.

An uncured liquid binder is applied to the nonwoven fabric 1. Urethane resin is used for the binder. A binder to which high hardness particles are not added is used. Non-woven fabric 1 coated with a binder is 3 to 4 m

EFFECTS OF THE INVENTION The non-slip sole of the present invention and the method for producing the same have the feature that, while reducing the production cost, they can be moved extremely safely without slipping on slippery rocks, and that they also have excellent durability. is there. The shoe sole of the present invention and the method for producing the same are applied to a non-woven fabric with or without high hardness particles applied with a liquid binder with or without addition of high hardness particles, followed by pressing. This is because the binder is adhered and the pressed non-woven fabric is restored by the restorability of the non-woven fabric to harden the binder in a state where numerous voids are formed between the fibers.

The non-slip shoe sole of the present invention realizes extremely excellent durability as compared with a shoe sole in which fibers are embedded in a foamed synthetic resin, because the binder that cures in the state where numerous voids are formed is a nonwoven fabric. This is because voids are created between the fibers while sufficiently covering the surface of the fibers. The shoe sole of the present invention has an infinite number of voids like the shoe sole in which the fibers are embedded in the foamed synthetic resin. However, since the foamed synthetic resin itself foams and hardens, the binder itself foams, and the foaming synthetic resin covers the surface of the nonwoven fabric fiber. For this reason, the strength of the binder coating the fibers is not sufficient, and excellent durability cannot be realized. On the other hand, the sole of the present invention is
Although there are innumerable voids, the surface of the fibers is coated with a binder that does not foam, and innumerable voids are provided between the fibers coated with the binder. Therefore, the fibers are strongly reinforced with the binder, and the strength of the shoe sole is significantly improved.

Further, in the non-slip shoe sole of the present invention, it is not necessary to use a foamed synthetic resin as a binder, and a binder for firmly binding fibers at low cost can be used. Also,
Even in the manufacturing process, it is not necessary to foam the binder, and it is possible to mass-produce inexpensively.
