Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a sole for ventilated shoes.

0002

[Conventional technology]

Conventionally, according to Utility Model Publication No. 33-13450, the pump chamber was connected to the heel part. Then, an exhaust groove was created through the exhaust check valve, and an intake groove was created through the intake check valve. A ventilated insole for shoes has been proposed. However, the exhaust check valve and the intake check valve However, each was formed separately from the insole itself and was attached to the insole. Therefore, the structure is complex and costly, and it is subjected to repeated loads during use. The check valve may fall off from the mounting part due to landing impact pressure or compression, resulting in long-term damage. However, the ventilation effect could not be achieved.

[Problem that the idea aims to solve]

This invention attempts to provide a breathable sole for shoes that has a simple structure and excellent durability. It is.

[Means to solve the problem]

This invention will be explained below with reference to the actual drawings. - A pump chamber 2 is provided in the heel by opening on the upper surface of the sole 1 formed of a rubber elastic body such as rubber. , a ventilation groove 4 that communicates with the inside of the shoe from the non-stepping part to the stepping part is provided externally in the non-stepping part or the heel part. A ventilation groove 6 that communicates with air is formed between the pump chamber 2 and the ventilation groove 4, and between the pump chamber 2 and the ventilation groove 4. Between the chamber 2 and the ventilation groove 6, there is a V-shaped wall 3 that is sharp in the ventilation direction and is integral with the sole 1, 5, and a notch 31 is formed at the tip of each of these V-shaped walls 3, 5 so as to be openable. ．． The gist of the invention is a sole for ventilated shoes characterized by the formation of a . In this design, high repulsion elastic bodies are placed partially in the pump chamber 2 as necessary. to promote pump action or by positioning shock absorbers. In this way, the landing impact pressure may be alleviated.

[0005] In this example, this idea was applied to a foamed midsole 1', and rubber foam was used. Foam formed from synthetic resin foam such as body, PVC, EVA, polyurethane, etc. A pump chamber 2 is formed by opening at the upper surface of the heel part of the midsole 1', and this pump A ventilation groove 4 that communicates with the inside of the shoe is formed from the pump chamber 2 to the toe area, and this pump Between the chamber 2 and the ventilation groove 4, there is a groove that is integrated with the midsole 1' and extends in the direction of the groove 4. A V-shaped wall 3 is formed with a notch 31 formed at the end. And pump room 2? A ventilation groove 6 that communicates with the outside air is formed from the bottom to the unexplored part, and the pump chamber 2 and the ventilation groove 6 are connected to the outside air. Between the grooves 6, a cut is made at the tip of the midsole 1' in the direction of the groove 6. An inverted V-shaped wall 5 with a groove 51 formed therein is formed. and in the embodiment the pump In the chamber 2, a shock absorbing material 21 made of a low-resilience foam or a gel-like viscoelastic substance is partially installed. It is inserted into the ground to alleviate the pressure of landing impact.

[0006] The midsole 1' constructed as described above has the outer sole 1'' attached to the bottom surface, and the sole of the shoe is During the shoe assembly process, a shoelace is attached to the upper surface of the midsole 1' through the midsole 8. It is fixed to the shoe sole 9, and the shoe is completed with the pump chamber 2 enclosed in the sole 1. this place In this case, the midsole 8 has ventilation holes 81 corresponding to the ventilation grooves 4 formed in the midsole 1'. ．． 81... are formed, and the ventilation groove 4 communicates with the inside of the shoe through these ventilation holes 81, 81... has been done.

[0007] In this way, when the assembled shoes are worn for walking or running, , or when body weight pressure (landing pressure) is applied to the heel of the foot during the initial process of running, The heel of the foam midsole 1' is compressed, and the pump chamber 2 is accordingly compressed. Then, the inverted V-shaped wall 5 is pressurized by the compressed air in the pump chamber 2, and its tip The V-shaped wall 5 is pressurized by the notch 51 provided at the tip of the V-shaped wall 5. The cut 51 opens the V-shaped wall 5 and the air in the pump chamber 2 flows through the ventilation groove 6. is discharged to the outside air through the After the initial process of walking and running, the weight pressure is applied to the heel of the foot. If the weight pressure is released from the heel of the midsole by moving toward the toe, The heel of the foam midsole 1' recovers to its original state due to its rebound resilience, and the pump chamber 2 is expanded, a load is imposed within the pump chamber 2, and at the same time the inverted V-shaped wall 3 is closed. Negative pressure is applied to the V-shaped wall 5, and the V-shaped wall 5 is When the letter-shaped wall 3 is opened and the air inside the shoe is sucked into the pump chamber 2 through the ventilation groove 4, In both cases, outside air flows into the shoe through the shoe opening and the like. When walking and running like this The pump chamber 2 repeatedly compresses and expands, and the V-shaped walls 3 and 5 act as check valves. As a result, the air inside the shoe is exhausted, and outside air is allowed to flow into the shoe from the shoe opening, etc. It will be done. In the embodiment described above, the V-shaped wall 3 is formed in an inverted V-shape toward the direction of the groove 4. , the inverted V-shaped wall 5 is formed in a V-shape toward the direction of the groove 6, respectively in a direction opposite to that of the embodiment. Then, outside air can be ventilated into the shoe through the ventilation groove 6, the pump chamber 2, and the ventilation groove 4.

[0008]

[Effect of the idea]

As described above, in this invention, the pump chamber 2 and the ventilation grooves 4 and 6 are provided on the upper surface of the sole 1, respectively. V-shaped walls 3 and 5 are formed with openings between the pump chamber 2 and the ventilation grooves 4 and 6, respectively. After forming the bottom with a mold, use a knife etc. to cut the tips of the V-shaped walls 3 and 5. It can be constructed by making notches 31.51 at each end, so the structure is Can be easily and inexpensively molded. Moreover, the V-shaped walls 3 and 5 that act as check valves are the sole 1 of the shoe. Since the sole is integrated with the sole, it is possible to provide a shoe sole that has a ventilation function over a long period of time.
