Shoe sole air cushion device

Abstract

The invention discloses a shoe sole air cushion device. The shoe sole air cushion device comprises an air cushion bag which is arranged in a shoe sole, and an elastomer of which the interior forms elastic buffer, an air throttle pipe is combined with a nozzle which is communicated with the inside and the outside and is provided with a valve ball, a suction inlet and a small-diameter outlet, the suction inlet and the small-diameter outlet are formed in the two ends, multiple stop blocks protrude on the inner wall of the suction inlet annularly, the small-diameter outlet is internally provided with a shrinking neck part and multiple lugs which protrude on the shrinking neck part annularly, the valve ball forms small-airflow gaps with the shrinking neck part when the nozzle of the air cushionnag exhausts air to slow down exhaust, forms large-airflow gaps with the inner wall of the suction inlet when the nozzle of the air cushion bag sucks air to quickly suck air for air inflation, and has elastic buffer of the elastomer, the air throttle pipe has the auxiliary buffering effect of slowing down of exhaust and quickly sucking air for air inflation, and the overall buffering effect of the shoe sole is effectively improved.

Description

technical field [0001] The invention relates to the technical field of shoe sole structures, in particular to a shoe sole air cushion device. Background technique [0002] Generally, air cushions are installed in modern running shoes or sports shoes, and the air cushions are used to provide the anti-compressive elasticity of cushioning the impact of the ground on the foot, so that the human foot can feel comfortable when stepping on the insole, without vibration due to the hard ground The impact is painful, and it provides the function of protecting the muscles of the feet and relieving fatigue. Therefore, many related companies have developed and improved insole technology. [0003] Currently, the elastic structure provided in the air cushion structure to provide elastic cushioning is nothing more than an elastic column structure or a spring structure. For example, the patent case of "Shoe Outsole Device with Air Cushion Function" in Taiwan, China Announcement No. M469774, ...

Problems solved by technology

[0008] Yet above-mentioned patent case M501747 existing air cushion structure figure 2 , image 3 As shown, setting 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, resulting in the difficulty of forming and manufacturing the gas structure and increasing the manufacturing cost, which is one of its shortcomings.

[0009] In addition, the function of the air bag in the above-mentioned patent M501747 air cushion device is to allow the gas outside the shoe to enter the air bag when the user is walking, and can pass through the exhaust ports, the through holes and the ventilation holes in sequence. The hole enters the shoe, that is, the patented airbag allows all the air to enter the shoe for ventilation when stepping on it, which can only achieve ventilation without auxiliary cushioning effect; while the airbag can only be provided by the elastic part of the internal single spring structure. The cushioning effect is very very limited, and it is difficult to effectively achieve the effect of slowing down the pressure on the heel of the user when walking, which is the second shortcoming

[0010] Therefore, how to deal with the existing air cushion structure in the previous case, the cushioning effect that can be increased by a single structure of elastic columns or springs is very limited, and the elastic columns or spring structures provided will increase the complexity of the structure and the difficulty of manufacturing To improve and create the shortcoming of the present invention is the difficult point that the present invention intends to solve
