Description

Waterproof and breathable sole

[0001] The present invention relates to a sole, and in particular to a waterproof and breathable sole.

Background technique

[0002] Most of the sweat secreted from the skin of human feet is concentrated at the bottom of the foot. The main sweat glands on the soles of the feet are concentrated in the fores, between the forefoot and the palm of the foot.

[0003] The sweat glands of the sole are one of the major sweat glands of the human body. Since the amount of movement of the foot is large and is in a relatively closed space, the amount of sweating is large. The sole absorbs the above-mentioned sweat for a long time, and because of the design requirements of the ordinary shoes (the sole is sealed and waterproof), the sweat tends to accumulate in the sole and cannot be volatilized in time. If so, the sole tends to smell and breed bacteria, which may cause people to suffer from foot diseases.

[0004] Especially for adolescents, teenagers have a lot of sweat on their feet, and often wear sneakers. The average sneakers are poorly ventilated, making it easier to make shoes smelly.

[0005] In the existing sports shoes, the volatilization of the increased speed sweat is achieved by improving the breathability of the upper. Since the sweat glands of the human foot are concentrated at the bottom of the foot, the sweat is directly discharged through the sole, which is undoubtedly the best way to solve the problem that the sole is easy to smell and breed bacteria.

[0006] The existing shoe sole using the waterproof and breathable membrane is realized by laying a waterproof gas permeable membrane on the inner side of the sole. This method has at least the following disadvantages: 1. The plane is waterproof, and the waterproofing of the sole must be required. The waterproof breathable membrane has a sufficient bonding surface with the sole surface to prevent the sole from leaking water, which largely limits the practical area of the waterproof and breathable membrane; 2. The fixed point: the main sweat glands of the human sole are concentrated between the toes and the feet. The palm part and the palm of the foot, the waterproof and breathable sole designed by the tile method, the main function of the breathability is mainly concentrated in a small area of the forefoot part of the shoe, and the design of the perspiration and ventilation is not strong and the effect is not good; The waterproof and breathable membrane directly bears the force and is easily damaged: The waterproof and breathable membrane directly bears the force, and the abrasion is large, and it is easy to be trampled.

Ϊ́οοο In addition, the above-mentioned waterproof and breathable film tiling method cannot be applied to the design of some relatively elastic soles, because these soles are large in elasticity and large in deformation during use, and the above-mentioned waterproof and breathable film is usually thin and relatively fragile. It is extremely vulnerable to damage when deformed greatly. The elastic sole is a sole of a sports shoe generally made of an EVA material, a foamed rubber or the like. This is also the reason why there are no translucent sports shoes that use foaming materials such as EVA and breathable film technology on the market.

[0008] The applicant's previous application number is PCT/CN2011/001258, the PCT International Patent Application entitled "Sole waterproof breathable film buckle", discloses a waterproof and breathable sole insert, which is used for Sole waterproof Breathable buckle for breathable film. The gas permeable membrane buckle is applied to the corresponding sole of the shoe having the vent hole, and has the function of preventing the liquid water from entering and permeable to the water vapor molecules, thereby evaporating the sweat of the sole of the sole without causing external water to enter the shoe. Inside, keep the soles dry and breathable and comfortable.

[00091] The applicant's prior application number is 2011203329830, the Chinese patent application entitled "A waterproof and breathable sole" discloses a waterproof and breathable sole, and specifically discloses the following technical features: a plurality of grooves are disposed, the bottom of the groove is open with at least one through hole to the sole, and a film buckle is mounted in the groove, and the film buckle structure is: corresponding to the groove The ring has at least one waterproof gas permeable membrane attached thereto. The invention is further improved on the basis of the above patents, and provides a waterproof and breathable sole with better waterproof effect.

The structure in which the outer side of the side wall of the film button is provided with an external thread may be provided on a film button provided with a waterproof chamfer, or may be provided on a film button which is not provided with a waterproof chamfer.

[0015] The waterproof gas permeable membrane is stretched at the bottom of the ring or the middle of the ring. The one or more waterproof gas permeable membranes may be a combination of a hydrophobic membrane or at least one hydrophilic membrane and at least one hydrophobic membrane.

[0016] The inner lower end of the film buckle is provided with an inner groove, a small ring is embedded in the inner groove, and the small ring is provided with a waterproof gas permeable membrane, and the small ring has a cross section of "7" Type or rectangular or trapezoidal.

[0017] The bottom of the sole groove is provided with a cushioning fabric and/or a mesh structure for preventing sand from entering.

[0018] A cushioning fabric is disposed between the waterproof gas permeable membranes.

[0019] The upper end of the membrane buckle has a convex edge extending inward.
