Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is mainly used for sports shoes, golf shoes, spikes, etc. When wearing shoes that are commonly worn, such as business shoes as well as other shoes that are commonly worn, To prevent the inside of shoes from becoming stuffy, emitting bad odors, and breeding athlete's foot, This invention relates to ventilation shoes that provide ventilation.

0002

[Conventional technology]

Conventionally, shoes mainly used for exercise or business shoes as mentioned above were used. As a means to prevent stuffiness inside the shoes, the upper surface and heel of the shoe should be covered with material. Therefore, breathable fabrics such as canvas or other breathable materials are usually used. It is. Also, when you run, the entire weight of your body is applied to the bottom of your feet, which can cause damage to your feet. To prevent fatigue, the soles of your shoes should be made of highly elastic material such as sponge. was used only.

0003

[Problem that the idea aims to solve]

However, the part of the foot that is most likely to get stuffy when wearing these shoes is the bottom of the foot. Even if the part of the shoe that covers the top of the shoe is made of a material with good breathability, ventilation will not reach the bottom of the foot. However, it was not sufficient as a means to prevent stuffiness. In addition, elastic materials such as sponge are used to reduce the impact of the load on the feet while running. As a result, shoes made of such materials have poor abrasion resistance and may shorten the lifespan of the shoes. There is a point.

0004 This invention is intended to solve the above-mentioned problems of conventional shoes, and allows the foot to touch the ground. By blowing compressed air out from the bottom of the inner surface of the shoe due to the load applied when the shoe is pressed, the By effectively ventilating the bottom of the foot, it eliminates various problems caused by foot stuffiness, and improves the landing area. The purpose is to improve the cushioning properties when

[0005]

[Means to solve the problem]

The present invention relates to a ventilated shoe means for achieving the above-mentioned object, and the invention relates to a means for ventilating the shoe to achieve the above-mentioned object. The sole of the shoe is made of a material with a certain degree of hardness, such as solid rubber, to form the sole surface of the shoe. The outsole has a flexible outsole such as a sponge, and is interposed between the outsole and the midsole. The outsole is partially joined to the midsole. , the midsole is between the outsole and the midsole, and is joined to the midsole and the outsole. At the same time, a gap is formed between the outsole and the midsole, and the gap is set in the midsole. This purpose can be achieved by communicating with the inner surface of the shoe through girder ventilation holes. can.

[0005]

[Effect]

The ventilation shoes of this invention allow the entire body load to be transferred to the shoes when the feet touch the ground while running. Add to the bottom of. Therefore, the flexible midsole is compressed and deformed by the load. In addition, the gap formed between the outsole and the outsole is also compressed, and the air in the gap is released into the midsole. Blows out from the pores onto the sole of the shoe.

[0006] When the foot leaves the ground, the midsole returns to its initial state with its own elasticity. As it returns, the gap between the outsole and midsole does not return to its original shape, Inhale air through the vents. In this way, ventilation is provided to the bottom surface of the foot.

[0007] On the other hand, the midsole itself has elasticity and can compress the air within the voids. has the effect of mitigating the impact, so it not only provides rich cushioning properties, but also protects the By using abrasion-resistant solid rubber etc. as the material of the sole, it is durable. Provides durability.

[0008]

【Example】

Next, an example of implementing the present invention will be described with reference to the drawings. 1 is the outer leather that covers the upper and circumferential surfaces of the foot, and the insole 2 is provided on the lower surface of the leather. The outsole 3 forming the sole surface of the shoe has relatively hardness like solid rubber, In addition, it is made of a material with strong abrasion resistance, and the front portion 3a and the inner sole 2 are joined. There is.

[0009] The upper surface of this outsole 3 descends from the front portion 3a at a large slope, and The rear part is formed to a nearly constant thickness almost following the curve of the sole surface of the shoe. And, between the insole 2 and the outsole 3 other than the front part 3a, there is a sponge etc. The midsole 4 is made of a highly elastic material such as A sole 4 is joined between the midsole 2 and the outsole 3.

0010 The outer periphery of this midsole 4 is formed to be the same as the outer periphery of the outsole 3, On the inner lower surface of the heel, there is a gap 4a with a large height and area, almost in the middle. It is formed by providing a support 4b in the center. The midsole 2 has ventilation holes 2a in the center on the left and right sides near the front side. The midsole 4 has an air guide extending from the void 4a to the ventilation hole 2a. The air gap 4a is formed inside the shoe through the ventilation hole 2a and the air guide groove 4c. is connected to.

[0011] Therefore, while walking or running, the load due to the weight of the body when the feet touch the ground The midsole 4 is compressed, so the heel area receives a particularly large load, so the heel area The void 4a provided in the space 4a will be particularly greatly compressed. Then, the air in the gap 4a passes through the guide groove 4c and flows out from the ventilation hole 2a into the shoes. As the air is discharged, the air blows out toward the sole of the foot inside the shoe.

0012 Also, due to the load applied to the sole of the foot at this time, the elasticity of the midsole 4 provides cushioning. This absorbs the shock, and the compression resistance of the air in the gap 4a also acts as a cushion. fulfill one's role. The elasticity of the midsole 4 and the compression resistance of the air are different in terms of cushioning properties, so The difference between the two provides appropriate cushioning, reducing pain when the foot lands on the ground and fatigue caused by impact. It is something that can be alleviated.

[0013] Then, when the foot leaves the ground, the midsole 4 retains its initial shape with its own elasticity. , the compressed void 4a tries to expand, and the ventilation hole in the midsole 2 Air inside the shoe is sucked from 2a through the air guide groove 4c. Therefore, some of the outside air is circulated inside the shoe, creating a convection state. This ensures air circulation to the soles of the feet and prevents the soles of the feet from getting stuffy. It is something that

[0014] Furthermore, since a support 4b is provided near the center of the gap 4a, this support 4b b also plays a role in restoring the shape of the void 4a, and the elasticity of the midsole 4 is fatigued. This supports the depression of the insole 2 on the upper surface of the gap 4a, and maintains the shape of the insole 2 that follows the shape of the sole of the foot. I'm trying to keep it that way.

[0015]

[Effect of the idea]

As mentioned above, the present invention uses a shoe sole made of relatively hard but durable material such as solid rubber. Even if it is made of abrasive material, the midsole is made of a sponge-like elastic material. Despite having cushioning properties, it is highly abrasion resistant and durable. If you reduce the thickness of the outsole, you can reduce the thickness of the midsole. The lightness of the material makes it possible to reduce the weight of the shoe.

[0016] The elasticity of the sponge that forms the midsole and the air resistance that compresses the voids Absorbs shock and provides appropriate cushioning properties as a shock absorber. be able to. Furthermore, airflow is created by air circulation through the voids provided within the midsole. This prevents the feet inside the shoes, especially the soles, from getting stuffy and maintains the comfort inside the shoes. It is possible.
