Description

  The present invention relates to an air cushion device for shoes, and in particular, a shock-absorbing air bag connected to the front end and the rear end of the shoe is provided, and the air bag and the air cushion are integrally molded. The present invention relates to an air cushion device for shoes that relieves impact force by filling with gas during walking.

In addition to decorating the appearance, the shoes are mainly used to protect the foot, and prevent the wearer's foot from being stabbed or bruised by a foreign object during walking or exercise. In addition, many shoes are provided with air cushions on the soles in order to increase the cushioning effect of the shoes in order to reduce the reaction and impact when the user wears the shoes. This air cushion improves the cushioning action of the shoe and provides the user with a more comfortable environment for the foot.
Referring to Taiwan Patent No. 437305 “Structure of Air Cushion Shoe for Supplying Gas” and Taiwan Patent No. 365746 “An Improved Structure for Vibration Isolation and Ventilation Shoes”, air is mainly applied to the front and rear ends of the shoe. In connection with the use of embedding a cushion, when a user steps on the gas, it is possible to circulate gas in the air cushions at the front end and the rear end, thereby exhibiting the action of absorbing vibration and impact.
Although the above-mentioned invention has the effect of ventilation and earthquake prevention, many of the conventionally known air cushion structures are made of sponge or plastic, so that the elastic modulus becomes too low and the effect of avoiding impact and vibration is effective. Not noticeable. In addition, after a certain period of time, the elastic characteristics easily deteriorate, and the effect of avoiding vibrations is completely lost. Considering this point, many vendors add springs in the air cushion to increase the elastic modulus, but since the springs have a spiral ring structure, the spiral ring structures of the layers fit together during compression. The compression action cannot be continued. A known shoe using an air cushion structure manufactured according to a spring becomes too hard as a whole, and the compression ratio is too small. Therefore, it does not have practicality and there is a need to actually improve.

As described above, the known structure has the following drawbacks.
That is, many conventionally known air cushion structures are made of sponge or plastic, have a small elastic coefficient, and the effect of avoiding impact and vibration is not remarkable. In addition, after a certain period of time, the elastic properties easily deteriorate and the ability to avoid vibrations is completely lost. Many vendors focusing on this point add springs in the air cushion to increase the elastic modulus, but since the springs have a spiral ring structure, the spiral ring structures of each layer fit together during compression. As a result, the compression action cannot be continued. Further, conventionally known shoes using an air cushion structure manufactured according to a spring are too hard as a whole, and the compression ratio is too small.
The present invention provides an air cushion device for shoes that solves the problems of the above structure.

  In order to solve the above-mentioned problems, the invention of claim 1 comprises an air cushion structure and an airbag structure, the airbag structure comprising a front airbag and a rear airbag communicated with each other, and The air cushion structure is housed in a rear airbag, and at least one elastic part is provided in the air cushion structure. The elastic part has a high compression rate, and the wire body is spirally wound. It has a funnel shape, and when the air cushion structure is compressed, the air bag structure can be filled with the base by sending the gas in the sealed storage space into the air bag structure. This is an air cushion device for shoes.

  The invention of claim 2 is provided with two cushion bodies in the air cushion structure, and the two cushion bodies correspond to at least one recess provided at the upper end and lower end of the elastic part, respectively. The concave portion can prevent the elastic component from easily sliding sideways when the cushion body sandwiches the elastic component, and is stored in the concave portion of the cushion body when the elastic component receives pressure. 2. The shoe air cushion device according to claim 1, wherein the elastic part reaches the most desirable compressibility effect.

  The invention according to claim 3 is characterized in that an adjustment device capable of adjusting the amount of gas sent from the air cushion to the airbag structure is provided on the air cushion structure. It is a cushion device.

According to the present invention, the elastic coefficient and the restoring force of the air cushion are increased by providing a funnel-type elastic part having a high compression ratio in the air cushion structure. Further, when the air cushion structure receives pressure, the air bag structure is filled with a gas (generated), and the air bag structure is filled with air, and the cushioning effect of the front and rear airbags Absorbs impact on the legs from the ground. In addition, the effect of preventing vibration by preventing damage to the skeleton and muscles that will be accumulated daily by the user without knowing due to the impact force, and combining elastic parts with high compression ratio Can be increased.
As described above, it is possible to provide suitable protection for the user's foot and to reduce the occurrence of injury and pain.
That is, it is possible to improve the disadvantages that the elastic coefficient of the known air cushion structure is too small and the compression ratio is not good.

The structure of the air cushion device for shoes of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, the air cushion structure 10 and the airbag structure 20 are combined,
The air cushion structure 10 is formed by combining two cushion bodies 11, an elastic part 12, an intake valve 13 and an exhaust valve 14.
Since the spiral annular structure of the elastic part 12 has a funnel shape with the wire wound spirally, the radii of the spiral annular structure of each layer are different from each other. Therefore, at the time of compression, there is no disadvantage that the compression ratio becomes too small by fitting with each other.
A circular recess 111 having a radius larger than that of the spiral annular structure of the outermost layer of the elastic part 12 is provided inside the cushion body 11, so that the elastic part 12 is interposed between the two cushion bodies 11. So that it does not easily leave.
The exhaust valve 14 is capable of putting gas into the airbag structure 20 when it is compressed by receiving pressure such as stepping on the air cushion structure 10.
The intake valve 13 in the air cushion structure 10 allows the pressure to be transferred by allowing gas to flow into the air cushion structure 10 when the return force of the elastic component 12 is expanded, and the user's walking By utilizing the stepping action at the time, the air cushion structure 10 is caused to circulate exhaust and intake air.

The airbag 20 is a combination of a front airbag 21, a rear airbag 22, and an air guide tube 23 connecting the airbags.
The airbag 21 generally has a plate-like shape, and a plurality of reinforcing structures 211 are distributed on the airbag 21,
The reinforcing structure 211 is for increasing the strength of the front airbag 21 so that the airbag 21 does not rupture or leak gas under repeated impacts. In addition, the air bag 21 is provided with an air inlet 212,
By connecting the intake port 212 and the exhaust valve 14 of the air cushion structure 10 to each other, the air cushion structure 10 can send gas into the airbag structure during exhaust,
The rear airbag 22 communicates with the front airbag 21 through an air guide tube 23, and the rear airbag 22 constitutes a concave accommodating chamber 221 that accommodates the air cushion structure 10 therein.
The storage chamber 221 can accommodate each component of the air cushion device.
Further, when assembling the present invention, the elastic part 12 is first placed in the recesses 111 of the two cushion bodies 11 and in the accommodating chamber 221 placed at one end of the exhaust valve 14 and the intake valve 13.
Further, the other end is exposed to the outside of the storage chamber 221 and is further sealed by a plastic film 222, and the internal gas is supplied and discharged only by the exhaust valve 14 and the intake valve 13.
Finally, the exhaust valve 14 is fixedly attached to the intake port 212 of the front airbag 21.
As described above, the air cushion structure 10 and the airbag structure 20 are elastic to the user by placing between the shoe sole 31 and the shoe insole 32 after the assembly and completion of the air cushion structure of the shoe of the present invention. And can provide anti-seismic effects.

As shown in FIGS. 4 and 5, when the air cushion structure 10 is not subjected to a load, the air cushion structure 10 maintains its upper and lower altitudes at the initial height by the elastic force of the elastic component 12. (See FIG. 4).
When the user's feet step on the air cushion structure and the air cushion structure 10 is pressed downward (see FIG. 5), the elastic part 12 is compressed. Since the elastic component 12 in the present invention has a funnel-shaped spiral annular structure, the radii of the spiral annular structures of the layers are different from each other, thereby causing a phenomenon that they are fitted to each other when compressed. There is no. Thus, the fully elastic part 12 can be fully compressed into the circular recess 110 of the two cushion pairs 11 and can be fully compressed, thus reaching a suitable compression ratio. Further, after the elastic part 12 is compressed, the upper and lower heights of the air cushion structure 10 change according to the compression, and the gas in the air cushion structure 10 is reduced in volume inside the air cushion structure 10. By doing so, the exhaust valve 14 flows toward the airbag structure 20, and the front airbag 21 and the rear airbag 22 are inflated accordingly, and thus the effect that the user cushions during walking is achieved. When the user lifts the foot again, the pressure of the air cushion structure 10 is released. Sexual component 12 acts to restore the original position by its elastic force. Therefore, the elastic part 12 returns the vertical height of the air cushion structure 10 to the original state. In addition, the air cushion structure 10 gradually increases in volume in the process of returning to its original state, so that the internal atmospheric pressure decreases, and the outside gas of the air cushion structure 10 also flows from the intake valve 13 into the air cushion structure. Enter. Up to the above is the process of intake.
When the user is walking or running, the air cushion structure 10 accompanies the movement of these foot portions because the foot portion of the user repeatedly steps down and pulls up upward. The process of exhaust and intake is repeated according to the pressurization and decompression action. Further, since the funnel-type elastic component 12 of the present invention has a suitable compression ratio, the effect is more prominent. Furthermore, at the same time as the user steps on, the air bag structure 20 can achieve the effect of elasticity and anti-vibration by exhibiting the effect of buffering the gas, reducing the burden on the user's foot, To make the user's walking or running more comfortable.

As shown in FIGS. 6 and 7, it is a second embodiment of the air cushion device for a shoe of the present invention, and main components are substantially the same as those of the first embodiment.
As a different structure, an adjustment device 40 is installed on the exhaust valve 14 of the air cushion structure 10.
The adjusting device 40 is fixed to the side surface of the shoe, and provides the user with an action of adjusting the air flow rate of the exhaust valve 15 of the air cushion structure 10 so that the air bag structure 20 is cushioned. By applying a difference in strength to the vibration absorption capacity, it can be applied to exercises with different degrees of impact.
It should be noted that the present invention is not limited to the above-described embodiment as long as it does not impair the features of the present invention, and further, changes in the effects of the inventive structure of the present invention are also included in the patent scope claimed by the present invention It is.
