Elastic air cushion

An elastic air cushion, especially for an air cushion used in a shoe body, and having an air cushion structure for absorbing and venting.

According to the conventional use of air cushions in shoes, such as shoes and casual shoes, the effect is only to enable the user to wear a cushioning effect when wearing the shoe body, so that the foot can reduce the injury while walking, and the operator also wants to use The air cushion is arranged to further improve the comfort of the shoe body. Therefore, a closed and open air cushion is developed. The closed air cushion is elastically deformed by the gas enclosed in the air cushion, and the open air cushion allows the gas to be used. The inside is connected to the outside world, and the elastic force is generated by the stress of the material of the body.

However, whether a closed or open air cushion is used, the structure has the following defects. If a closed air cushion is used, although a certain elastic force can be maintained, the closed air cushion loses the cushioning effect if it leaks. If you use an open air cushion, you can worry about the problem of air leakage, but it has the problem of insufficient or excessive support. It is not resistant to use and reduces the comfort when you wear it. The problems and the problems caused by the above-mentioned conventional techniques are to avoid the problem that the quality and the comfort level are not improved due to the poor air cushion structure, and the problem that the relevant industry is eager to solve.

The purpose of the creation is to use a support column having an elastic deformation function to be placed in the chamber to provide a support effect, and secondly, to add to the structure. Overall comfort.

In order to achieve the above purpose, the elastic cushion of the present invention has a bottom layer, a surface layer and a connecting layer, and the surface layer is disposed above the bottom layer, and the connecting layer is connected to the periphery of the bottom layer and the surface layer, so that a chamber is formed between the bottom layer and the surface layer, and the chamber is provided with a chamber The elastic deformation of the support column, the two ends of the support column are respectively connected to the bottom layer and the surface layer, and a channel is formed in the support column, and the channel penetrates the bottom layer and the surface layer.

In the above elastic air cushion, the support column is provided with a vent hole for connecting the passage and the chamber, so that the user can repeatedly ventilate and exhaust when the air cushion is stepped on.

In the above elastic air cushion, the connecting layer is further provided with a vent pipe, and the vent pipe is provided with a one-way shutter, which can greatly increase the gas flow rate of the vent hole of the support column when the user repeatedly steps on the air cushion, and the effect of lifting the ventilation and exhausting. .

By the above technical means, when the present invention is used in the shoe body, the elastic force during use can be increased, and the comfort is excellent without affecting the durability of the air cushion, and is extremely practical.

Referring to the first to second figures, it can be clearly seen from the figure that the air cushion 10 of the present invention has a bottom layer 1, a surface layer 2 and a connection layer 3, the surface layer 2 is disposed above the bottom layer 1, and the connection layer 3 is connected to the bottom layer. 1 and the periphery of the surface layer 2, a chamber 4 is formed between the bottom layer 1 and the surface layer 2, and then the connection layer 3 is provided to connect the chamber 4 with the outside space. The ventilating tube 31 is provided with a plurality of supporting columns 5, and the two ends of each supporting column 5 are respectively connected to the bottom layer 1 and the surface layer 2, and a channel 51 is formed in each of the supporting columns 5, and each channel 51 is penetrated. The bottom layer 1 and the surface layer 2.

Referring to the second and third figures, it can be clearly seen from the figure that when the present invention is in the state of use, the air cushion 10 is placed in the shoe body 7 in advance, and the vent pipe 31 of the connecting layer 3 is made. Exposed to the shoe body 7, when the user wears the shoe body 7 and walks, when the user's foot generates a downward force (as shown by the hollow arrow in the third figure), most of the force It will act on the laterally disposed surface layer 2 of the air cushion 10, and at the same time, the supporting force of the surface layer 2 is given to the surface layer 2 by the support column 5 disposed vertically to allow the air cushion 10 to generate an elastic force, thereby achieving the shock absorbing effect, and further, when the surface layer 2 When the force is toward the bottom layer 1, the gas in the chamber 4 is pushed, and then moved toward the outside by the vent pipe 31 (as shown in the third figure) to achieve the function of exhaust and buffer, and continue to be the surface layer. 2 When the force is released from the state, the surface layer 2 is restored to the original position by the action of the support column 5, and at the same time, the air enters the chamber 4 by the vent pipe 31; in combination, when the user steps are repeatedly stepped on, the generated Excellent elasticity, allowing the feet to be significantly reduced during walking The pressure, thereby reducing damage.

Referring to the fourth and fifth figures, it can be clearly seen from the figure that the air cushion 20 of the present invention is further provided with a vent hole 52 through the support post 5 for communicating the passage 51 and the chamber 4. Therefore, when the user steps on the air cushion 20 to force the surface layer 2, the gas in the chamber 4 is simultaneously discharged by the surface layer 2 to the outside by the vent pipe 31 and the vent hole 52, and is vented by the vent hole 52. The discharged gas first enters the passage 51, and then the gas is drained into the shoe body 7 by the passage 51, so that the gas flow amount of the shoe body 7 can be increased to achieve the function of ventilation and exhaust to increase the comfort during wear.

Referring to the sixth figure, it can be clearly seen from the figure that the one-way shutter 6 is further disposed in the vent pipe 31 of the air cushion 20, so that when the user repeatedly steps on the air cushion 20, the one-way shutter 6 is restricted. The directionality of the gas flow in the chamber 4, therefore, When the surface layer 2 is stressed, the one-way shutter 6 obstructs the gas flow direction in the chamber 4, thereby greatly increasing the gas flow rate of the vent hole 52, and the gas continues to enter the shoe body 7 through the passage 51, thus repeatedly stepping on the air cushion 20, so that The gas flow of the shoe body 7 is greatly increased, and the effect of ventilation and exhaust is increased, which is advantageous for increasing the comfort of the shoe body 7 when worn.

Therefore, the present invention is capable of solving the problems and deficiencies of the prior art. The key technology is that the chamber 4 of the air cushions 10, 20 is provided with an elastically deformable support column 5, and the support column 5 supports the surface layer 2 and the bottom layer. 1, with the arrangement of the chamber 4, so that the air cushions 10, 20 can produce excellent elastic force and support effect to enhance the buffering effect, in addition to increase the comfort when wearing, without affecting the durability of the air cushions 10, 20. Very practical.
