Description

Waterproof breathable sole

Technical Field

The utility model relates to a waterproof and breathable sole.

Background

The sole is rather complex in construction and in a broad sense may include all of the materials forming the sole, such as the outsole, midsole and heel. In a narrow sense, only the outsole is referred to, and the common characteristics of the general sole materials should have the characteristics of wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy adaptation to the foot shape, difficult deformation after shaping, heat preservation, easy moisture absorption and the like, and simultaneously should be matched with the midsole to have the brake function of preventing slipping and easy stopping when the foot is changed during walking. The sole materials are of various types and can be divided into natural base materials and synthetic base materials. The natural bottom materials comprise natural bottom leather, bamboo, wood and the like, and the synthetic bottom materials comprise rubber, plastics, rubber and plastic combined materials, regenerated leather, elastic hardboard and the like.

The sole adopting the synthetic base material has better waterproof performance, but poor ventilation is caused due to the sealing formed after injection molding, the ventilation of the upper layer can be carried out only by depending on the vamp, but the sole of a human body is the key position for sweating, so the wearing comfort of the sole is poor.

Therefore, the waterproof and breathable sole capable of increasing exchange air inflow and air permeability is designed.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a waterproof and breathable sole which can increase exchange air intake and air permeability.

The utility model discloses a realize through following technical scheme:

a waterproof and breathable sole comprises a body, wherein an inwards concave shoe groove is formed at the top of the body in an injection molding mode, a groove is formed after the part, close to the right side, of the shoe groove is downwards concave, a U-shaped elastic piece is glued and fixed in the groove and is attached to the bottom surface of the groove, and the front and back side surfaces of the shoe groove, two ends of the elastic element extend upwards to the outside of the body, the elastic element is provided with a hollow inner cavity, two ends of the inner cavity are communicated, and the inner cavity penetrates through the elastic piece, when the elastic piece is stepped on, the air in the elastic piece is evacuated, when the human body lifts feet in a striding way, the elastic piece rebounds and sucks air, after the elastic piece is glued and fixed with the groove, the middle part of the elastic part forms a flat surface supported at the bottom of the sole of the foot, and a plurality of air exhaust holes capable of exhausting air are arranged at the outer wall of the elastic part.

Preferably, a plurality of hollow capsule balls are formed in the inner cavity in an injection molding mode at positions corresponding to the positions below the flat surface; the design purpose of the balloon is to increase the resilience of the inner cavity, and when a human body lifts the foot in a striding mode, the arrangement of the balloon can enable the inner cavity to be expanded better, so that the air suction amount is increased.

Preferably, a movable insole made of rubber is glued at the position of the inner right side surface of the shoe groove, the left end of the movable insole can be opened after being turned up clockwise, air holes are uniformly distributed on the surface of the movable insole, the air holes vertically penetrate through the movable insole, the movable insole is flatly contacted with the bottom of the shoe groove, and an oval hollow protruding part is formed at the position, corresponding to the heel, of the movable insole through injection molding; the movable insole has the main functions of increasing the air permeability between the movable insole and the bottom of the shoe groove, and simultaneously, air exhausted by the elastic part can be better diffused in the shoe groove, so that the air permeability effect is improved.

Preferably, the body is made of PU material.

This product does not upgrade sole structure, adopt conventional anti-skidding line can.

The body of the product has better waterproofness, can avoid the upward permeation of water vapor on the ground, and ensures the drying of the sole. When the human body walks, trample the elastic component, when trampling, utilize the extrusion and the expansion of elastic component, can inhale the both ends of outside air through the inner chamber, inhale the back, along with next trampling, extrude the air again, the air part of extruding is discharged from the both ends of inner chamber, realizes taking a breath, and partial air is discharged from the exhaust hole, and the air effect of following exhaust hole department is in shoes. Realize the air cooling in the shoes, reduce sweat, increase the gas permeability.

The utility model has the advantages that: this product can extrude the elastic component along with the action of the person of dress lifting the foot and lowering the foot in practical application to and utilize the resilience inspiration air of elastic component, realize the exchange in the shoes air and the outer space of shoes, realize the circulation of air, realize the cooling of sole, the structure of this product is comparatively simple, and the cost is comparatively cheap, is fit for using widely.
