DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a new type of fire-fighting shoes excellent in workability, wearing feeling and safety.

[0002]

2. Description of the Related Art In recent years, the equipment of firefighters has been modernized one after another, and helmets and fire protective clothing have been very successful, but firefighters still have rubber. It is well known that length is used.

[0003] Although rubber length is good in water repellency, it is known that it has poor air permeability, and it has not only the drawback that it is easy to have stuffiness, bad smell and mold, but also has a problem in fire resistance. The site environment is the worst and often causes injuries due to stepping out of nails, etc.In addition, it is slippery and dangerous because of work in firefighting water, especially when extinguishing fire in cold regions There was a problem with the quickness of fire extinguishing work.

[0004]

SUMMARY OF THE INVENTION The improvement of these problems has been a problem for a long time, and various ideas have been proposed in part. However, a shoe structure suitable for fire-extinguishing work as a fire-fighting shoe has been considered. There has been a strong demand for the appearance of fire-fighting shoes that can be replaced by rubber boots.

[0005] The present invention, however, discloses, although not completely, what has now been completed with what is considered to be the best desired for firefighting shoes using commercially available materials.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a structure in which the surface materials of the cylindrical portion and the upper portion are made of natural leather impregnated with fluorine, and The inside of the sewn part of the surface material is sealed with waterproof, water-resistant, moisture-permeable and breathable tape, and the backing is made of a fiber cloth treated with deodorant, antibacterial, deodorant, and mold-proof treatment And
Also, using aramid fiber cloth as the backing material of the upper part,
The outsole is mainly made of fire-resistant rubber, and a part of the ground contact surface has a composition containing trapezoidal microparticles in order to improve adhesion to the ground, and an appropriate number of rubber that hardens below freezing and softens at room temperature A fire shoe characterized by a book spike, and a mid-sole with a mid heel that has a protective metal plate between the insole and the outsole and a shock absorbing sponge in the heel. is there.

[0007]

The outsole according to the present invention has fire resistance and not only has high adhesion to the ground when walking in firefighting water in warm weather, but also has spikes during firefighting work and movement in cold regions. Since it is hardened, it has the effect of preventing slippage and increasing work efficiency much more than in the case of a conventional rubber length. In addition, the microparticles that enhance the adhesion to the ground are trapezoidal and angular, so that the microparticles are less likely to fall off, have better adhesion than when using simple particles, and between the shoe sole and the ground. It breaks water and oil films and fits directly to the ground, giving it excellent grip. Despite the use of natural leather with good appearance, it has waterproofness and breathability, and also has excellent protection function, and protects the shin and instep from high heat and chemicals. Further, the protective metal plate prevents the nail from being pulled out, so that it is possible to obtain fire-fighting shoes that are highly safe and have a shock absorbing effect when landing from a high place or when running.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of the present invention.
2 is a front view, FIG. 2 is a side view, FIG. 3 is a longitudinal side view, and FIG. 4 is a bottom view, where A is a tubular portion, B is an upper portion, and C is an outsole.

The surface materials 1 and 2 of the cylindrical portion A and the upper portion B of the embodiment are made of natural leather called Rezanova (water-repellent natural leather manufactured by Daikin Industries, Ltd.) in which fluorine is permeated to collagen fibers. It was used. This surface material is excellent in water repellency, has higher water repellency than conventional waterproof leather having a surface coating, and has excellent breathability.

[0010] The backing material 3 is made of an orderless-processed nylon fiber cloth which is provided with a deodorizing, antibacterial and deodorizing function called orderless (registered trademark of Daiyu Shoji Co., Ltd.). . Nylon fiber cloth has excellent sweat-absorbing properties and has the effect of preventing moisture from returning to the surface, and it is effective for wearing firefighters who work hard together with the effect of preventing the generation of ammonia and lower fatty acids that cause odor by orderless processing There is an effect that a suitable use environment can be maintained.

Reference numeral 4 denotes an intermediate material used for the upper portion, which is made of aramid fiber cloth and has the characteristics of high heat resistance, chemical resistance, and carbonization without contact and shrinkage even at high temperatures. It has a structure that helps prevent injury to the foot due to the effect of reducing cuts such as nails that try to enter the instep because it is a fiber that has high cutting resistance.

Reference numeral 5 denotes a waterproof, water-resistant, moisture-permeable, air-permeable waterproof tape (in the embodiment, a fluororesin porous tape is used) adhered to the sewing system portion, and prevents water from entering from the seam. In addition to preventing water from leaking out, it is excellent in heat resistance and chemical resistance, and does not impair the moisture permeability and air permeability of the affixed portion even when a wide tape is used.

The sole part 6 of the outsole C is made of fire-resistant rubber as a main material, and the toe part 7 and the inner part of the heel part 8 are made of rubber mixed with trapezoidal microparticles. A spike 9 made of rubber, which hardens below freezing and softens at room temperature, is integrally formed. The trapezoidal angular microparticles were used to improve the adhesion to the fire-resistant rubber soles, to prolong the anti-slip effect of the microparticles, and to form a water or oil film between the shoe sole and the ground. This is to improve the clipping property by breaking the ground and directly fitting to the ground.

The rubber used for the spike 9 is as follows.

Most of the soft compounded vulcanized molded products of natural rubber and synthetic rubber have the property of maintaining their softness even at -20 ° C to -30 ° C below the freezing point.

However, for natural rubber, isoprene rubber, butyl rubber, and styrene butadiene rubber, the amount of styrene resin is increased, and for acrylic rubber and nitrile rubber, synthetic resins such as polyvinyl chloride, acrylic resin, urethane resin and the like, which are compatible with the rubber, coumarone, and chileben are used. When a tackifier such as a phenolic resin is added to the rubber and the amount thereof is increased, the property of softness and elongation at normal temperature starts to harden rapidly at an ice temperature, that is, near 0 ° C.

Such resin properties are well known,
A rubber compound that cures rapidly from 0 ° C. to near minus can be obtained by selecting the polymer and adjusting the addition amount of the above-mentioned resins.

A 0.25 mm stainless steel plate 10 (protective metal plate) is inserted between the inner bottom and the outsole.
The insole has a mid-heel insole 11 with a shock absorbing sponge in the heel. The material and thickness of the protective metal plate are not limited to the above-mentioned materials and thickness.

As described above, the fire shoes according to the present invention include:
The cylinder part A and the upper part B are made of natural leather with a fluorinated skin, so they are waterproof and have a very good appearance. The backing material 3 has deodorant, antibacterial and deodorant materials. Since it is used, it can be worn not only during work but also as daily wear.

Further, since the protective metal plate 10 is inserted and the aramid fiber cloth is used for the upper part, it is possible to prevent a stepping-out accident of a nail or the like at the time of fire extinguishing work and an injury to the instep.

Further, when used in a cold season or a cold region, the special spike 9 hardens to serve as a spike, and the toe portion and the heel portion 8 are made of special rubber containing trapezoidal angular microparticles. Because of this, these particles break the curtain of water and oil created between the shoe sole and the floor, fit directly on the ground, grip and prevent slipping during fire fighting, so work at slippery fire fighting sites Can be done quickly without worrying about slipping.

[0022]

According to the present invention, there is an effect that it is safer than the conventional rubber length, and it is possible to wear comfortably without foot stuffiness or smell as in the case of using the rubber length. It is excellent.
