The present invention relates to a fire protection shoe for thermal insulation by the insulation material which is built between the bottom or upper of the shoe and the finishing material to block the heat of the outside or the heat of the ground.

In general, thermal fire fighting shoes of the prior art insert a thin aluminum thin-walled insulation material in the middle of the outer member and the inner member formed of a urethane material and molded using a seal or an adhesive on the outer periphery of the insulation material.

However, shoes manufactured in this form have a problem such as sweating on the feet by separately transmitting the hot cloud of geothermal heat generated from a fire site or a summer asphalt and a specific workplace without filtration.

Therefore, firefighters who extinguish fire in a fire building or workers working at a stationary place such as asphalt sites often wear fire-fighting shoes with thin aluminum sheet insulation to prevent heat and burns. This is because it needs to be processed for bar, so its water-induced property is lowered, and the waterproof effect is reduced. There was a problem that they had to suffer the tired pain.

Thus, the present invention was devised to solve the above problems, inserting a fiber material having a thin heat insulation function in the middle portion of the outer member and the inner member to integrally use a seal or adhesive on the outer peripheral adhesive portion It is an object of the present invention to provide a thermal fire fighting shoes to block the high temperature from the outside by molding.

Fire protection shoe for thermal protection of the present invention for achieving the above object, in the shoe for thermal insulation that can block the temperature transmitted from the outside, sequentially stacked toward the inner direction from the outer member of the shoe 100 Thin waterproof insulation fireproofing material (lining materia, 25), a moisture-permeable skin (27) as a lining material, temperature-controlled heat-resistant felt (29), a thin thermal insulation function in the middle of the outer member and the inner member Inserting a fiber material having a includes an inner felt 31 made of an integral heat insulating material using a seal or an adhesive to the fusion portion of the outer periphery.

In addition, in the thermal fire fighting shoes, it is preferable that the outer member and the middle portion of the inner member is bonded to the outer periphery of the surfaces facing each other and adhered to each other, and then sewn into the sewing chamber 40.

Fire protection shoes for thermal protection of the present invention has a function to block the heat generated from the outside or the ground to the foot.

Therefore, the thermal fire fighting shoes of the present invention, the inner felt 31 which is an insulation material inserted into the middle portion on the sole 10 of the shoe 100 to block the flow to the outside of the external heat source or internal heat and prevent moisture Fine holes are drilled at regular intervals. The inner felt 31, which is the heat insulating material, exhibits about 20 times better heat insulating effect than the heat insulating material, and is thinner with a volume of about 1/500-1/250, which is more effective since the heat insulating material is formed of fibers. In addition, it is non-flammable, thermal insulation function, clean, light, does not deform, and does not deteriorate even in damp places. It is processed to breathe fine holes at regular intervals to prevent moisture.

Next, when described in detail based on the embodiment of the accompanying drawings of the present invention.

Hereinafter, an embodiment of a thermal protection fire shoe according to the present invention will be described with reference to FIGS. 1,2 and 3, but the same components as in FIG. 1 for the description of FIGS. 2 and 3 are the same as those given in FIG. The description thereof is omitted in detail.

Fire protection shoes for thermal protection of the present invention is the height from the sole to the top line is more than 30.0 cm, the weight is less than 2.5 kg when the weight of the rubber.

The thermal fire protection shoe of FIG. 1 includes a waterproof outerwear fireproof rubber material 25 (see Table 1) and a lining material that are sequentially stacked inward from the outer member of the shoe 100.

Here, the lining material is composed of a moisture-permeable sheath (27, see Table 2), a heat-controlled heat-resistant felt (29, see Table 3) and the inner felt 31 is a heat insulating material.

In FIG. 1, the bottom sole 10 is made of a thick rubber material or urethane component to be cushioned with a ball 18 which is a protrusion for preventing slipping at the bottom thereof, and the bottom sole 10 is adjacent to the bottom sole 10. It has a pull ring 14 at the top.

As shown in FIG. 2, the insulation material is sewn into and fixed to the edge of the waterproof outer refractory rubber material 25 and the edge of the sole 10 by using a bar thread and / or an adhesive 40.

The inner felt 31, which is the heat insulating material, has a plurality of minute through holes 35, such as needle holes, at regular intervals.

The outer fire resistant rubber material 25 of the thermal fire protection shoes is a high molecular compound exhibiting rubbery elasticity by vulcanization or crosslinking, using natural rubber and synthetic rubber, and the waterproofing function is sufficiently maintained.

The moisture-permeable sheath 27 is made of fine holes at regular intervals to prevent moisture. The moisture-permeable sheath 27 has a moisture-permeability test of at least 6000 g / m 2/24 h in accordance with the potassium acetate method of KS K 0594 (Method of Water Permeability Test of Textile Products).

In addition, the lining material (lining material) that is the inner member of the fire protection shoes for thermal insulation is in contact with the worker's socks and block the flow to the outside of the external heat source or internal heat.

In addition, the anti-heating felt 29 and the inner felt 31 is a pure lining material fibers of only 99.9% of the material inserted only 0.1% of the molding reinforcement.

The inner felt 31, which is a heat insulating material applied to the present invention, forms a large number of small pores that can breathe as a high purity lining material of 99.9% on both sides, and is highly breathable and weakens the flow of external or internal heat sources. Block more than 97%.

The applicant has made the following test to test the actual flow of heat flow for the thermal protection fire fighting shoes of the present invention.
