Abstract

A shoe having an improved air chamber and an air valve structure is provided to attain an air circulation flow system inside the shoe at any time by making air flow in through an inhale valve or an exhale valve formed at the sole or the heel. A shoe comprises: an inhale valve(5), an exhale valve(6), thin layers(13), a bottom(1) or a gourd shape baffle plate(9). The sole includes an air chamber(3) and an air passage(2) that are divided by a baffle plate(4). A bottom plate(14) is formed on the air chamber, and a sole(7) and the bottom plate are adhered to the bottom of the shoe. The inhale valve and the exhale valve are formed at the side wall of the air chamber and the baffle plate such that when the air chamber is compressed, air is sent from the air chamber to the air passage via the exhale valve. When the air chamber returns to its initial state, fresh air flows into the air chamber via the exhaust valve.

The present invention relates to the air sac and gas valve structure, in particular, fresh air from the pores of the shoe insole into the intake valve of the through hole or into the intake valve of the side wall of the shoe heel chamber, the inner wall of the shoe heel is U-shaped It has a structure, and a plurality of support walls are installed around the air passage to form a perforated isolation space, and a plurality of gourd-shaped obstruction plates are installed at the front end of the air passage for any purpose of air circulation flow at any time in the shoe. To reach.

In general, the structure of the gas valve of the conventional ventilation system shoes is to install a unidirectional intake valve and an exhaust valve in the shoe rear axle air chamber, and the structure of the gas valve is a thin film is inserted in the vertical gap at the horizontal pore side. The thin film causes the gas valve to be unidirectional. The mold structure is complicated and the production cost is high, and the inner wall for receiving the weight in the shoe heel is not provided, and only the unidirectional intake valve and exhaust valve structure are installed, so the ventilation effect is limited due to the insufficient amount of ventilation. .

An object of the present invention is to provide an improved and developed air bladder and gas valve structure to solve the problems of the prior art mentioned above.

In order to achieve the above object, in the present invention, by providing a continuously improved and developed air sac and gas valve structure, the gas valve direction is changed in the side wall and the obstruction wall of the shoe heel, one is the intake valve and the other Is an exhaust valve, which allows fresh air to come in from the intake valve of the shoe insole pores or the side wall of the shoe heel compartment to achieve a bidirectional intake effect; The U-shaped inner wall is installed in the shoe heel to strengthen the shoe heel strength, and the structure allows fresh air to be intaken and exhausted in different directions.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention.

Example 1

The present invention relates to air sacs and gas valves, and mainly includes an intake valve (5), an exhaust valve (6), a thin film (11) (13), a shoe insole (7), a shoe sole (1), or a gourd-shaped obstruction plate ( 9) It is composed of a back element, among which the shoe sole 1 (see Fig. 1) is separated into a space such as the air chamber (3) and the air passage (2) by the obstruction wall (4), the bottom plate (14) It is installed on the air chamber, and the shoe insole 7 and the bottom plate 14 are attached to the sole of the shoe 1, respectively, and the shoe sole protrudes downward from the bottom of the air chamber 3, and the side wall of the shoe sole air chamber is formed. And a one-way intake valve 5 and an exhaust valve 6 are installed in the barrier wall 4 area, and when the air chamber 3 of the shoe heel is compressed, air in the air chamber passes through the exhaust valve 6. It is sent to the air passage (2), when the air chamber (3) of the shoe heel is returned to its original state, fresh air enters the air chamber (3) via the intake valve (5) from the outside.

The exhaust valve structure (see FIG. 2) of the barrier wall 4 provides a through hole 10 in a portion within the wall of the barrier wall 4, and the through hole 10 is a bottom portion of the air chamber 3. In the inclined shape in the upper direction of the air passage (2), the enlarged portion 12 is formed on the upper portion of the air passage, and the thin film 11 is installed in the enlarged portion (see Fig. 4). When the air in the air chamber 3 is compressed, the air pressure opens the thin film 11 of the exhaust valve 6 to allow air to enter the shoe through the through hole 10 (see FIG. 3). When the air chamber 3 of the shoe heel is restored to its original state, the opened thin film 11 is pushed in the opposite direction to allow the through hole 10 to be closed. In other words, the exhaust valve 6 is closed. The intake valve 5 is integral with the side wall of the air chamber, a U-shaped gap is installed near the air chamber, and an active thin film 13 is installed in the gap, and the air is compressed when the air in the air chamber 3 is compressed. The pressure blocks the thin film 13 of the intake valve 5 (see FIG. 5), and when the shoe heel air chamber 3 returns to its original state from the compressed state, the air pressure opens the thin film 13 to Fresh air enters the air chamber 3 via the intake valve (see FIG. 6).

In the present invention, a plurality of coarse isolation spaces and support walls are installed around the air passage (2), and the coarse isolation spaces reduce the weight of the sole of the shoe, and the support wall strengthens the structure of the shoe sole, and the air chamber (3) Install the base plate (14) on the top to divide the weight received evenly, and installed a plurality of gourd-shaped baffle plate (9) in front of the air passage (2), The inlet is in the direction of the exhaust valve 6 so that air flows out of the exhaust valve 6 and changes in a vertical direction through the gourd-shaped obstruction plate 9, and the insole 7 has several gourd-shaped obstructions. By installing the shoe insole pores 8 corresponding to the plate 9, the air flows through the gourd-shaped obstruction plate 9 to the shoe insole pores 8 to have air communicate with and through the shoe.

In addition, the present invention can be installed in reverse gas valve (see Fig. 7), the exhaust valve 6 is installed on the side wall of the shoe sole air chamber (3), the unidirectional intake valve (5) in the obstruction wall (4) area Fresh air is sent from the shoe sole pore (8) to the gourd-shaped obstruction plate (9), through the intake valve (5), to the air chamber (3), and again from the air chamber (3). We can achieve the purpose to send to (6) and circulation aeration.

Example 2

A flow hole 26 is installed on the side wall of the shoe rear axle, and a through hole 25 is installed in the obstruction wall 24 between the shoe sole air chamber 23 and the air passage 22, and the active thin film 32 is formed. The gas valve is inserted into the flow hole 26 and the through hole 25, and the relatively small casing 34 of the gas valve forms the exhaust valve 31 toward the air passage 22 in the obstruction wall 24. In addition, the relatively large casing 34 of the gas valve forms the exhaust valve 31 inside the shoe rear axle, that is, inside the flow hole 26 (see FIG. 9), and the relatively large casing 34 of the gas valve is obstructed. An intake valve 30 is formed from the wall 24 toward the air passage 22, thereby having a bidirectional aeration function.

By installing the gas valve on the shoe sole 21, when the shoe heel of the air chamber falls off the ground, the shoe heel is restored to its original state, and fresh air flows out of the shoe insole pores 8 and flows through the air passage. Pass 22 through the intake valve 30 of the obstruction wall 24 (see FIG. 10), the air pressure pushes the active thin film 32 of the intake valve 30 into the air chamber 23 (FIG. 9). When the shoe heel of the air chamber 23 is in contact with the ground (see FIG. 11), the shoe heel is compressed to the inside by a force, and is externally passed through the exhaust valve 31 of the inner wall of the air chamber 23. Flow out to complete the ventilation. In addition, when the shoe heel of the air chamber 23 falls off the ground, the shoe heel is restored to its original state, and fresh air flows into the intake valve 30 on the side wall of the air chamber (see FIG. 8). Air flows from the exhaust valve 31 of the obstruction wall 24 to the air passage 22 when the shoe heel of the) contacts the ground, and again the shoe insole pores corresponding to the mock plate 29. ) To send air to complete the ventilation function.
