Waterproof ventilating soles

Abstract

The invention relates to waterproof ventilating soles. Each waterproof ventilating sole comprises an outer sole, a waterproof ventilating assembly and a ventilating middle sole which are arranged from bottom to top, wherein the outer sole at least comprises two strip-shaped units; the upper surface of each strip-shaped unit is provided with a plurality of upper concave surface parts which are arranged at intervals in the length direction, and the lower surface of each strip-shaped unit is provided with a plurality of lower concave surface parts arranged at intervals; the at least two strip-shaped units are horizontally integrated into the plate-shaped outer sole or one part of the outer sole in a row, and the upper concave surface part and the lower concave surface part on the strip-shaped unit are respectively interlaced with the upper concave surface part and the lower concave surface part of the adjacent strip-shaped unit; the upper part of the upper concave surface part and the lower part of the lower concave surface part are respectively provided with an upper gas chamber and a lower gas chamber; and the upper gas chamber of the strip-shaped unit of the outer sole is mutuallycommunicated with the lower gas chamber of the adjacent strip-shaped unit. The clean and dry gas can enter the gas chamber on the upper surface of the outer sole by a ventilating hole from the gas onthe lower surface of the outer sole, the humid hot gas in shoes can reversely flow, and the wearing comfort of the shoes can be improved.

Description

technical field [0001] The invention relates to a shoe sole suitable for various types of shoes, in particular to a waterproof, breathable, non-slip and shock-absorbing shoe sole. Background technique [0002] Shoes are an indispensable daily necessities for people. With the development of human society, it has also developed from a single protective function to a consumer product for people in a specific environment. Today's shoes not only require protective functions but also certain requirements. comfort performance. With the movement of the human body, the temperature of the feet rises and generates heat. However, the shoe is a relatively closed shell with poor air permeability. It is far from enough to rely on the gap at the edge of the shoe to dissipate heat, and a large amount of heat will accumulate inside the shoe. , the feet will be wet, sweating, and uncomfortable. After wearing for a long time, it is extremely easy to cause diseases such as foot odor and beriber...

AI Technical Summary

Problems solved by technology

In the application number CN200720305601.9, inclined grooves are provided from the forefoot on the inner side of the outsole to the waist fossa, and horizontal and longitudinal convex beams are arranged inside to form a grid breathing and ventilation room, and gas convection grooves are provided on the convex beams , the breathing and ventilation chambers communicate with each other, and there is also a groove on the heel. On both sides of the inclined groove from the forefoot to the waist fossa, there are through ventilation holes for exchanging with the outside air. Waterproof and breathable materials are glued on the inner sole of the shoe. This structure has a certain degree of air permeability, but there is no mesh breathing room in the front of the sole, that is to say, the air permeability is only limited to the forefoot to the waist and heel, and the air permeability is poor. There is a mesh breathing room inside the sole. The air chamber and the gas convection groove, and there are through holes on both sides of the sole, the structure is complex, and the manufacturing process is relatively cumbersome

In the application number CN200720169972.9, a convex post is provided and a small vent hole is left on it, a fastener device is added, the structure is more complicated, and the manufacturing process is more troublesome

In the application number CN96215833.X, the forefoot of the sole is covered with rubber pillars and the gaps formed by the glue pillars, which become a space for breathing and exchanging gas with the inside of the shoe body. There are small ventilating holes on the side of the forefoot of the sole, which are similar to the front ones. The structure is simpler, but the effective ventilation space is small, and the gas inside and outside the shoe cannot be fully exchanged.

[0004] In the patents whose application numbers are CN96197403.6 (WO97 / 14326) and CN98804920.1 (WO98 / 51177), the so-called shoe sole tread is made of porous elastomer, and large holes are arranged on the sole as passages for gas exchange. The axis of the hole is perpendicular to the surface of the sole, so it is still unavoidable to be blocked by materials with suitable size and hole, and once it is blocked, it is difficult to remove it. The utilization rate of the surface area of ​​the waterproof and breathable membrane is relatively low. This structure has no shock absorption function. If you want to absorb shock Need to add additional related parts

In the application number CN0382259.3 (WO2004 / 028284), the function of shock absorption is achieved by adding related parts on the heel, and the surface area utilization rate of the waterproof and breathable membrane is also improved, but the structure is more complicated and the process is complicated.

In other relevant patents, there are related mechanical parts such as one-way valves to achieve waterproof and breathable functions, but the structure is more complicated and the production cost is very high.
