Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention
The present invention relates to athletic shoes, boots and footwear such as sandals used in outdoor sports and the like, and more particularly to footwear sole members such as shoe soles.

[0002]

2. Description of the Related Art Rubber soles are generally used for leisure and sports, but the rubber soles are slippery when wet with water, and are suitable for use in places where there is water such as fishing or hill climbing. Needs attention. Therefore, recently, as a shoe sole of leisure shoes for fishing in the sea or in the river or climbing a river, a felt (nonwoven fabric) sole and a spike sole, which are hard to slip with respect to a rubber sole, have become widespread and have become mainstream.

[0003] The felt bottom is formed by shaping a non-woven fabric of a fiber such as polypropylene into a shoe sole shape, and when stepping on a wet rock at the felt bottom, the felt bottom absorbs water to reduce the biting property to the rock. Make it better and less slippery. The spike bottom is formed by driving a plurality of spikes into a rubber bottom or the like, or is formed by integrally forming large projections (spikes) on the bottom, so that the spikes do not bite into the ground and are hard to slip.

[0004]

When the felt bottom is made coarser, the fibers are loosened earlier and the durability is deteriorated. Therefore, the eyes are made finer by needling or the like, and the felt bottom is made harder. When stepping on a place where water moss or mud is present on the felt bottom, there is a concern that the water moss or mud is clogged in the eyes of the felt bottom, the felt bottom becomes a smooth surface, and the felt easily slips. Further, the felt bottom is excellent in water absorbency, but poor in dewatering property for naturally dehydrating absorbed water. In addition, when continuously stepping over rocks with mossy water, such as when climbing a swamp, there is a problem that the effect of the anti-skid gradually decreases.

[0005] The spike bottom is not slippery because it penetrates into mud, moss and the like on the ground, and is excellent in durability. However, when used in a hard place such as concrete or rocky place, the load on the foot is large. There is a problem that hurts the foot or accelerates fatigue. In addition, the spike bottom may damage the ground by biting into the ground, and there is a risk of damage or injury depending on what is stomped on.

[0006] It is an object of the present invention to provide footwear such as leisure shoes utilizing the advantages of the felt bottom and the spike bottom.

[0007]

SUMMARY OF THE INVENTION The present invention is directed to a shoe sole in which rubber or resin is impregnated into a fiber laminate aggregate in which organic or inorganic synthetic fibers, metal fibers or natural fibers having crimps and / or curls are laminated. The above object is achieved by footwear provided with a shaped bottom member.

[0008] Here, the fibers of the fiber laminated aggregate are
3,000 denier is desirable in order to enhance the anti-slip effect of the bottom member. As this kind of fiber, an organic or inorganic synthetic fiber such as polyester or polyethylene, a metal fiber, or a natural fiber is selected and used. As the fiber laminated aggregate, a non-woven fabric, a woven fabric, a cotton wool, or a core-sheath fiber body is selected and used. The rubber or resin impregnated in the fiber laminate aggregate to bond the fibers together is styrene rubber, butadiene rubber, styrene butadiene rubber, acrylonitrile rubber, isoprene rubber, nitrile rubber,
Chloroprene rubber, acrylic rubber or acrylic resin, urethane rubber or urethane resin, ethylene-vinyl acetate resin, cellulose acetate resin, synthetic rubber such as acrylic rubber, natural rubber, vinyl acetate resin are used. .

The above-mentioned bottom member having a thickness of about 1 to 2 cm is suitable as shoe soles or sandals. Such a bottom member is a vulcanized or cross-linked rubber that bonds fibers together to make the durability good even when the coarseness is increased, and a bottom member having a thickness of about 1 to 2 cm is used for leisure. It has been found that when used for the soles of shoes, it is less likely to slip on water moss and the like, and has a moderate cushioning property to reduce the burden on the feet.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a sole member 1 used as a sole for a shoe. And vulcanized or crosslinked. The sole member 1 is formed into a flat shoe sole shape, and is fixed to the bottom surface of the shoe (not shown) by bonding or the like. Depending on the type of shoe using the sole member 1,
The thickness and the constituent material of the bottom member 1 are selected.

The bottom member 1 is suitably used as a sole of leisure shoes for fishing and hill climbing. Fiber 2 of this bottom member 1
Preferably has a crimp or curl. Specifically, polyester, polyethylene, polyamide, polypropylene, polyacrylonitrile, polyvinyl chloride, polyvinylidene chloride, vinylon, organic such as polycarbonate,
Inorganic synthetic fibers, metal fibers and natural fibers are used.
The fiber 2 has a fiber density of 1 to 3000 denier and a bottom member 1.
It is desirable in expecting a spike effect that makes it hard to slip,
Preferably, a fiber degree of 50 to 3000 denier is an appropriate range.

The production of the fiber laminated aggregate 3 using the fibers 2 may be performed by laminating the fibers 2 in a multilayer shape in a plane and needling. Further, the impregnation of the rubber 4 into the fiber laminate aggregate 3 is performed by spraying or dipping a thermoplastic resin, by spraying an emulsion rubber or a resin onto the fiber laminate aggregate 3, or by impregnating these solutions with the fiber laminate aggregate 3. May be carried out by immersing it.

The rubber 4 is used as a binder for bonding and bonding the fibers of the fiber laminate aggregate 3 to each other, and makes the bottom member 1 suitable for shoe soles such as strength, durability and cushioning properties. This rubber 4 includes styrene rubber,
Use of synthetic rubber such as butadiene rubber, styrene butadiene rubber, acrylonitrile butadiene rubber, isoprene rubber, nitrile rubber, chloroprene rubber, acrylic rubber, urethane rubber, natural rubber, vinyl acetate resin, and cellulose acetate resin is possible. It is.

In the above-mentioned bottom member 1, the rubber 4 increases the durability of the fiber 2 and the whole bottom member, and makes the cushioning property of the bottom member 1 good as a tall shoe sole. Further, by impregnating the fiber laminated aggregate 3 with the rubber 4 and vulcanizing or cross-linking the rubber, the rubber 4 increases the overall strength of the fiber laminated aggregate 3 even when the coarseness of the fiber laminated aggregate 3 is increased. As appropriate. Actually, if the bottom member 1 is made coarse with a thickness of 1 to 2 cm using fibers 2 with a fiber degree of 1 to 3000 denier, it is difficult for water moss and mud to be clogged as well as the spike bottom, and it is easy to come off even if it is clogged It has been found that a shoe sole having a large (non-slip effect) has a non-slip effect close to that of straw sandals, and a safe sole that does not damage the ground or the like can be obtained.

Further, since the bottom member 1 is formed in a flat plate shape and has an appropriate cushioning property, the burden on the foot is lightened similarly to the felt bottom. Further, the bottom member 1 of the present invention, in which the rubber 4 is entangled with the fiber 2, has the same or higher durability as the felt bottom, and exhibits a non-slip effect for a long time. Further, even in a case where the rubber 4 entirely impregnated in the bottom member 1 makes the water absorption and dehydration of the bottom member 1 good, the rubber 4 can continuously step on a wet rock such as a swarm. The anti-slip effect is continuously and well exhibited.

The bottom member 1 'in FIG. 2 is a sole for leisure shoes made of the same material as the bottom member 1 in FIG. In the case of the bottom member 1 ', it is manufactured by impregnating a rubber 4 into a fiber laminated aggregate 3' in which fibers 2 having crimps or curls are three-dimensionally laminated and vulcanizing or crosslinking.

The bottom member 1 'of FIG. 2 is manufactured with the same machine and the same conditions as the bottom member 1 of FIG. You. The spike effect, the cushioning property, and the dewatering property of the bottom member 1 ′ of FIG. 2 are substantially the same as those of the bottom member 1 of FIG. 1, and the description of the effect is omitted.

The sole member of the footwear according to the present invention is not limited to the sole of leisure shoes, but may be used for soles of rain boots, sandals and slippers.

[0019]

According to the present invention, the anti-slip effect and the cushioning property of footwear provided with a vulcanized or cross-linked sole member impregnated with rubber in a fiber laminated aggregate are appropriately adjusted by the material and amount of the fiber and rubber. Therefore, it is possible to provide a footwear which is hard to slip on wet rocks, water moss, mud, and the like, and which can reduce foot fatigue even when walking and has excellent comfort. In particular, when the bottom member is used as a sole for leisure shoes such as fishing and climbing, it is hard to slip and is safe, and even if water is absorbed, it is released immediately and shows a continuous anti-slip effect. Thus, it is possible to provide shoes suitable for leisure and outdoor sports having a sole for reducing the burden on the foot.
