Description

Air cushion device with cushioning and relaxing shoes

The invention relates to a shoe air cushion device with cushioning and pressure relief, which is arranged in the shoe body to buffer and relieve the pressure of the sole of the foot during walking, running and jumping.

Shoes are a very important product for the soles of the feet. They can prevent the soles of the feet from being exposed to damage from foreign objects on the road when walking. They also have the effect of keeping warm in cold environments. Therefore, shoes are quite indispensable for people. The comfort of a pair of shoes is naturally indispensable to the cooperation of the insole. When a human is standing, its weight is distributed on the forefoot and the back of the foot. Therefore, the insole must be designed for the pressure on the forefoot and the back of the foot. The design of early insoles was mostly produced by foaming, with poor elasticity and short life.

Insole improvement. There are many styles of air cushions on the market. The more common shoe air cushions are as shown in the seventh figure of Taiwan Patent Publication No. M271427 "Shoe Body Air Cushion Structure for Cycling Ventilation", which have airbags and inflatable structures and are connected to each other. , When the back sole of the foot presses on the inflatable structure, the air inside the inflatable structure will infuse the airbag to inflate and expand the airbag to relieve the pressure on the forefoot. When the backfoot is lifted, the pressure on the inflatable structure is released, and the airbag is inflated. The structure expands by taking in external air, thus achieving the effect of relieving the pressure on the forefoot and the back of the foot. However, although this design can provide the wearer's foot comfort, there are problems. When the inflatable structure is repeatedly pressed, it will continue to move forward. The air bag enters the air. When the air inside the air bag is overfilled, it will cause the air bag to expand too much. The swelling makes the forefoot uncomfortable due to the compression between the airbag and the top of the toe, and a person will produce a strong pedaling force during running and jumping. When the airbag is overfilled and pressed by a large force, it will explode. The possibility of opening, if the insole burst open, it will cause the human body to lose balance and fall is quite dangerous.

The present invention provides a shoe air cushion device with cushioning and pressure relief. The toe air cushion can deflate by itself, and solves the problem that the conventional insole air bag will be too inflated, so that the forefoot is squeezed between the air bag and the toe top and causes discomfort.

In order to achieve the above-mentioned effect of solving the conventional problems, the present invention provides a shoe air cushion device with cushioning and stress relief, which includes: a heel air cushion, an elastic member is arranged inside, and the outer periphery of the heel air cushion is respectively provided with a first unidirectional Air valve and a second one-way air valve, the heel air cushion uses the second one-way air valve to draw external air; and a toe air cushion, the outer periphery of which is provided with a vent valve and an air inlet respectively, the toe toe The air cushion is connected with the air inlet and the first one-way air valve by a pipeline, and pressure is applied to the heel air cushion, and the gas inside it flows to the first one-way air valve, the pipeline, and the air inlet The inside of the toe air cushion and the gas inside the toe air cushion are gradually discharged by the vent valve, and the maximum flow rate of the vent valve is less than the maximum flow rate of the air intake of the toe air cushion.

From the above content, it can be seen that in addition to solving the problems of conventional insoles, the structure of the present invention also provides a cushioning effect when the soles of the feet are pressed down. For example, when jumping to the ground, the deflation valve of the toe air cushion is slowly deflated, and the internal space of the toe air cushion is gradually reduced. Retraction allows the forefoot to lower slowly to reduce impact.
