Description

   Sole air cushion device   

The invention relates to the technical field of sole structures, and in particular to a sole air cushion device.

Generally, modern running shoes or sports shoes are provided with air cushions, which use air cushions to provide cushioning pressure-resistance elasticity on the feet, so that the human foot can feel comfortable when stepping on the insoles, instead of oscillating with the hard ground The impact is painful, and it provides the functions of protecting the muscles of the feet and relieving fatigue. Therefore, many related companies have developed and improved the technology of insoles.

And the elastic structure currently provided in the air cushion structure provides elastic cushioning, except that it uses an elastic column structure or a spring structure, for example, the patent case of the "outsole device with air cushion function" of the Republic of China Publication No. M469774, which The patent states as its abstract: "An elastic air cushion is arranged in the shoe body so that the shoe body has excellent elasticity; the air cushion has a cavity therein, and a plurality of elastically deformable support columns and support columns are arranged in the cavity. Through the passage, when the user repeatedly steps on the air cushion, the support effect given to the air cushion by each support column can generate excellent elastic force, so that the foot can produce a better cushioning effect, so the shoe body can be improved in use. Comfort and durability. ".

As mentioned above, the patent case M469774 is familiar with the air cushion structure, and a plurality of elastically deformable support columns are arranged in the cavity. Although it can give the air cushion the supporting effect to generate excellent elastic force, so that the foot has a better cushioning effect; however, For example, the air cushion structure shown in the second figure of the patent case M469774 will cause many complex structures to grow inside the air cushion because of the plurality of support columns provided, which will cause the difficulty and cost of the gas structure to be formed and increased. One of its disadvantages.

In addition, the single cushion structure of the above-mentioned air cushion structure simply relying on the internal support column can only increase the cushioning effect, which is obviously difficult to effectively achieve the aforementioned comfort and durability effects, which is the second disadvantage.

In addition, as in the case of the patent of the "breathable air cushion shoes" of the Republic of China No. M501747, the patent is as described in item 1 of the scope of patent application: "1. A breathable air cushion shoes, which includes: a shoe upper; a An outsole is coupled to the upper and is provided with a receiving groove facing the upper; a midsole is provided in the receiving groove and is provided with a plurality of through holes corresponding to the front of the user's foot An insole provided on the midsole and provided with a plurality of ventilation holes to communicate with the through holes; and an air cushion device provided in the accommodation slot and located on the outsole and the midsole In the meantime, the air cushion device has an inflatable bladder and an annular tube, wherein the inflatable bladder corresponds to the heel of the user, and has a one-way air inlet valve communicating with the outer edge of the outsole, and the inflatable bladder An elastic member is arranged in the longitudinal direction to abut the upper and lower edges of the inflatable bladder, and the annular tube system corresponds to the front of the user's foot, and is connected to the inflatable bladder through a communication tube, and the annular tube The inner edge ring is provided with a plurality of exhaust ports, so that when the user walks, the gas outside the shoes can enter the inflation Bladder, and can enter the shoes through the exhaust ports, the through holes and the ventilation holes in order to achieve the effect of ventilation. "

As mentioned above, the patent case M501747 is familiar with the air cushion structure, although as described in its description, the elastic resetting ability of the elastic member in the inflatable bag can make the overall inflatable bag like a cushion body with cushioning effect, which can be used to slow down the use The pressure on the heel when the person walks, thereby protecting the heel of the user from aches and pains, to avoid causing foot diseases such as varicose veins and plantar fasciitis.

However, the above-mentioned patent case M501747 shows the structure of an air cushion, as shown in Figs. 2 and 3. The placement of an elastic member with a spring structure in the air bag of the air cushion device will also increase the complexity of the internal structure of the air cushion, causing the gas structure to be manufactured during molding Difficulty and manufacturing costs are therefore increased, which is one of the disadvantages.

In addition, the inflatable bag in the above-mentioned patent M501747 air cushion device is so that when a user walks, the gas outside the shoes can enter the inflatable bag, and can sequentially pass through the exhaust ports, the through holes, and the breathers. The hole enters the shoe, that is, the patented airbag allows all the gas to enter the shoe for ventilation. It can only achieve ventilation without auxiliary buffering effect. The inflatable bag can only be provided by the elastic member of the single spring structure inside. Its buffering effect is very limited, and it is obviously difficult to effectively achieve the effect of alleviating the pressure on the heel of the user when walking, which is the second disadvantage.

Therefore, how to learn the air cushion structure according to the previous case, the cushioning effect that can only be increased by the single structure of the elastic column or spring is very limited, and the provided elastic column or spring structure will increase the complexity and manufacturing difficulty of the structure. It is the difficulty that this case intends to solve in order to improve creators with such shortcomings.

A gas nozzle, the elastic body elastically supports the inner wall of the air cushion bag to form buffer elasticity, the gas nozzle is combined with a section of a gas valve tube; the gas valve tube has a valve ball, an suction port at both ends, a small diameter At the outlet, the inner wall of the suction port has a plurality of stoppers protruding in a ring row, the small-diameter outlet has a reducing neck and a plurality of protruding blocks protruding in a ring neck at the narrow row, and the valve ball is arranged at the suction port. Between the plurality of stoppers and the plurality of small-diameter outlets, the diameter of the inner wall of the suction port is larger than the valve ball to form a large air gap. The diameter of the inner wall of the narrowed neck portion in the small-diameter outlet is smaller than the valve ball. When the ball abuts against the convex block, it forms a small air gap with the inner wall of the narrowed neck. Among them, the valve ball of the throttle valve rests on the multiple convex blocks of the small-diameter outlet when the valve of the air cushion airbag is exhausted and contacts the narrowed neck. Creates small air gaps to slow exhaust When the valve ball is inhaling, the valve ball abuts a plurality of stoppers of the suction port and forms a large air gap with the inner wall of the air suction port to quickly inhale and inflate. According to this, the throttle valve adjusts the air cushion bag to slow down. Auxiliary buffering effect for exhaust and fast insufflation.
