Description

Shoes with cold and hot protection {omitted}

The present invention relates to a shoe having a cold, heat blocking function that is built in the bottom or insole of the shoe to block the temperature of the ground.

In general, a thin aluminum sheet-shaped insulation material 15 is inserted into a middle portion of a bottom member 10 and an inner insole 20 formed of a conventional urethane material, and a seal 45 or an adhesive is used at the fusion edge of the outer periphery. The flooring material 10 and the inner insole 20 were molded in one piece. And in the same manner as in the shoe sole 10, the upper insole 60 and the lower insole 55 by inserting the insulation material 15 in the middle so that the shoe insole 50 can be produced.

In general, the flooring or insole of a shoe selects a cushioned material for absorbing foot comfort and shock when walking. Particularly, the material used is a urethane type, and the insole is used inside the shoe. In the past, functional shoe insoles have been manufactured and manufactured in various forms for special purposes such as odor removal and moisture removal. However, the shoe insole manufactured in such a form has a problem such as cold feet and sweating due to separate transmission of cold heat of the geothermal heat and winter land generated in a specific workplace and summer asphalt.

As a result, workers who work in a cold winter place or place workers inside barracks often wear thick socks to prevent footache and frostbite. It was difficult to take the pain of foot discomfort because it was a requirement of prohibition for workers who are in need of quick work or important guard work.

The main object of the present invention is to solve the problems as described above is inserted into a thin aluminum sheet-shaped insulation material 15 in the middle of the flooring material and the inner insole as a urethane material seal (45) Or by using an adhesive to form the flooring material 10 and the inner insole 20 in one piece, the cold and heat blocking functions are provided to protect the feet by blocking the cold coming from the floor in winter and the high temperature generated in a specific workplace. The purpose is to provide a shoe having.

Hereinafter, the present invention will be described in detail with reference to the embodiments of the accompanying drawings.

Figure 1a is a perspective view showing the structure of the flooring by cutting a portion of the shoe (shoe) of the present invention, Figure 1b is a perspective view showing a cross-sectional view of Figure 1a of the present invention, blocking the cold and heat generated from the ground to the foot It provides a shoe having a function for.

Therefore, the insulation material 15 inserted into the middle portion of the bottom material 10 to the inner insole 20 of the shoe 100 blocks the flow to the outside of the external heat source or the internal heat and fine holes at regular intervals to prevent moisture. It is characterized by being plated. The insulation material 15 exhibits 20 times the thermal insulation effect of the existing thermal insulation materials (Schiropol, urethane foam, glass wool ...), and thinner to a volume of about 1/500-1/250 of the conventional insulation material more effective to be. It is especially sticky and can be easily glued. 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, and it is used in the space, cold polar regions, and hot deserts with a crossover temperature of 100 ℃ or higher as well as the effects of moisture-proofing and water vein blocking.

Silver coated on other conventional rock wool, glass wool, asbestos, and polystyrene foam products has the ability to absorb moisture in the air (absorption of existing products: 0.1-0.25 mg / sq.cm), resulting in increased thermal conductivity. In the case of deterioration of performance, the mat type rock wool, asbestos, and glass wool showed a result that the thermal conductivity increased gradually after about two years at a relatively high use temperature, and the thermal insulation effect began to decrease gradually.

However, the heat insulating material 15 applied to the present invention is a high purity aluminum thin film of 99.9% on both sides, and has no absorbency.

In order to test the actual flow of radiant heat flow, the following tests were carried out.

Experimental conditions: The gap between the hot side and the cold side of the hollow wall was 38 mm, and the temperature on the hot wall was 100 ° C. and the cold side was 0 ° C.

Experimental installation: Experiment 1. Wall on both sides ... 12 mm pine wall

Experiment 2. The insulation material 15 was attached to the cold wall of the inner air layer.

When bulk insulation is used in general buildings, the air density of hollow layers between walls is low. The hollow layer and the volume insulation absorb more than about 90% of radiant heat.

By absorbing only about 3% of the radiant heat, the total heat flow shows tremendous insulation from 319 BTU's to 123 BTU's.

result. In view of the above experiments in the United States, a conductivity of 0.006 W / m.K was found. If the insulation material 15 was tested for two installations of composite specimens, the result would be that the installation of extruded Schiropol 157 mm, which is on the bulk insulation grade classification table, would not prevent the enormous radiant heat flow. ) Provides almost perfect insulation by preventing conduction and convection heat as well as radiant heat.

The experiment is not the data tested by applying to the shoe field, but illustrates that the function and effect of the present insulation material 15 can be applied to the shoe as it is.

Figures 1a to 1b is an illustration showing the grouping as an example showing the cut portion of the front surface 10 is made of a thick rubber material or a urethane component at the bottom is configured to be cushioned with a protrusion for preventing slipping at the bottom and The insulation material 15 is inserted, the inner insole 20 is laid, and the ends of the outer skin 25 and the edge of the flooring material are integrally sewn and fixed by using the seal 45 to the adhesive and the like. The material 15 is composed of a plurality of minute through-holes 65 such as needle holes at regular intervals.

And Figure 2a is a perspective view showing the shape in which the insulation is inserted into the shoe insole of the present invention and Figure 2b is a cross-sectional view showing a state in which the heat insulating material of the present invention Figure 2a is inserted.

In the shoe insole 50 for blocking heat and cold to insulate the foot to insulate the foot, consisting of a heat insulating material 15 located between the upper insole 60 and the lower insole 55, the upper And the heat insulating material 15 embedded in the lower insole is very thin in aluminum sheet type, so even if it is built, it is not exposed to the outside, and the heat insulating material 15 includes a plurality of through-holes 65 to prevent moisture from occurring. Keep your feet from smelling.

Here, it is preferable that an adhesive material is applied to the outer circumference of the upper and lower insoles facing each other so that the upper and lower insoles are sewn into the adhesive or seal 45 by inserting the insulating material.

As such, the present invention is a shoe having a function of blocking the transmission of cold and heat generated from the ground by inserting the insulating material 15 in the middle of the sole 10 of the shoe or the shoe insole 50. In the cold winter, the heat of the foot is taken to the ground to prevent the foot from getting cold and prevent frostbite, and to block the heat generated in the place where the high temperature of a certain workplace occurs. The insulation material contains a molding reinforcement, and small pores are formed, so it is breathable, thereby reducing sweating when wearing shoes, thereby keeping the feet clean.
