Problems solved by technology

[0002] At present, the thermal insulation materials used in footwear (such as soles, insoles, and uppers) are mainly fiber-based, such as thermal insulation cotton and glass fiber cotton, but this type of thermal insulation material only has the effect of heat storage and heat preservation. Under the low-temperature environment, it is still impossible to block the loss of heat energy due to conduction, convection, and radiation effects. Therefore, we can only increase its thickness to reduce the loss of heat energy. The relative size of the entire shoe will become larger and heavier. Wearer is considerably hampered in movement
[0003] The other is to combine thermal insulation cotton with a layer of aluminum foil in a needle-punched manner, in an attempt to reduce the heat radiation effect by virtue of the metal reflectivity of the aluminum foil, but this structure still cannot reduce the heat conduction and heat convection effects, and its warmth retention effect is not good. ideal
[0004] U.S. Patent No. 6,065,227 discloses a kind of waterproof footwear, which is to combine a layer of shoe covers made of waterproof and breathable (wet) materials in the middle of the upper and the inner liner by sewing, although the waterproof lining can be used Block the water on the outside of the shoe, but in extremely cold climates, when the low temperature from the outside is transferred to the inside of the shoe at a higher temperature, the waterproof lining made of waterproof and breathable membrane will expand due to thermal expansion and contraction In this way, the temperature difference between the inside and outside of the shoe is large, and condensation occurs inside the shoe, while the cold air outside is due to heat convection. , heat conduction, and heat radiation will gradually penetrate into the shoes, and the condensed water accumulated in the shoes will gradually form condensation and freezing due to the continuous low-temperature conduction outside the shoes, causing the entire pair of shoes to lose their heat preservation function
[0005] In addition, China Taiwan Patent No. 349,854 discloses a shoe with a shoe inner boot. The shoe inner boot is mainly made of EVA or PU material on the upper and lower surfaces of the elastic block, and then laminated with a layer of cloth. (or insulation cotton) covering parts, then cut and sewed into a shoe shape, so that the inner boot plug of the shoe is placed in a shoe, and tightly covers the foot to reduce the external cold air convection to the inside of the shoe to achieve the effect of heat preservation. Although this kind of shoe inner boot has a certain heat preservation effect, it still cannot completely block the gradual loss of temperature and freezing in the shoe due to the effects of heat conduction, heat convection, and heat radiation. situation
[0006] To sum up, the above-mentioned thermal insulation materials for shoes are still not suitable for areas with relatively severe climates. A thermal insulation shoe article (material) that can prevent the internal temperature loss of shoes is urgently waiting for the industry to develop and break through.

Embodiment Construction

[0041] Such as figure 1 and figure 2 As shown, the first preferred embodiment of the article of footwear with cold-proof and heat-insulating device of the present invention has a cold-proof and heat-insulation unit 100, which includes at least one porous material layer 1, two radiant heat-resistant layers 2, and one encapsulation layer 3.

[0042] The porous material layer 1 has a surface area conforming to the sole of the foot, and is made of a porous elastic material. In this embodiment, it is best made of open-cell polyurethane (PU). , and the inside of the material is mixed with molecular sieve with hygroscopic effect and activated carbon for eliminating peculiar smell. The internal air chamber 12 (in the figure, its pores are enlarged to facilitate the labeling) to prevent the conduction of its internal heat energy (stagnation of air). In addition, the porous material layer 1 is better to use a black base material to reduce heat conduction coefficient, and reduce the ...

Abstract

A kind of shoes with cold-resistant and heat-insulating mechanism is disclosed. Said mechanism is composed of at least one porous layer and an encapsulating layer for said porous layer and made of the air-tight thermoplastic material. Said encapsulating layer consists of an internal sheet, an external sheet and a sealed internal cavity made of said internal and external sheets and with a sealed vacuumizing opening.

Description

technical field [0001] The present invention relates to a kind of article for shoes, in particular to a kind of article of footwear with a cold-proof and heat-insulating device. Background technique [0002] At present, the thermal insulation materials used in footwear (such as soles, insoles, and uppers) are mainly fiber-based, such as thermal insulation cotton and glass fiber cotton, but this type of thermal insulation material only has the effect of heat storage and heat preservation. Under the low-temperature environment, it is still impossible to block the loss of heat energy due to conduction, convection, and radiation effects. Therefore, we can only increase its thickness to reduce the loss of heat energy. The relative size of the entire shoe will become larger and heavier. The wearer is considerably hindered in movement. [0003] The other is to combine thermal insulation cotton with a layer of aluminum foil in a needle-punched manner, in an attempt to reduce the he...
