Pneumatic elastic band and inflation system applying the same

Abstract

A pneumatic elastic band includes an outer layer, an inflation portion, and an air nozzle. The outer layer is an elongated elastic structure. The inflation portion is arranged in the outer layer, andcomprises a plurality of inflatable portions and a plurality of communicating portions. Each communicating portion is connected between adjacent inflatable portions and defines a plurality of voids. The air nozzle is arranged on the surface of the outer layer and communicates with the inflation portion. A plurality of inflatable portions of the inflation portion are inflated by introducing gas into the inflation portion through the air nozzle, and the inflatable portions are inflated and compressed inwardly, thereby tightening the shoe. As that gas is led out of the inflation portion through the air nozzle, the inflation portion is deflate and relaxed back to an uninflated state, thereby untying and tieing the shoe.

Description

technical field [0001] The invention relates to a pneumatic elastic band and its applicable inflation system, in particular to an inflatable pneumatic elastic band and its applicable inflation system. Background technique [0002] Generally speaking, most traditional footwear uses ordinary shoelaces as a tool for loosening and fixing the feet. However, footwear with shoelaces has many inconveniences in wearing. For example, when the shoelaces fall off during wearing activities, the shoelaces must be re-fastened to continue the activity, which often causes inconvenience and waste of time in activities. Additionally, wearing footwear with regular laces is potentially dangerous. For example, when the shoelaces are accidentally loosened, it is easy to cause others to step on them and trip them, and they may also be caught in the gaps of escalators, bicycle chains or motorcycle footbolts, etc., which may easily cause accidents.

AI Technical Summary

Problems solved by technology

[0002] Generally speaking, most traditional footwear uses ordinary shoelaces as a tool for loosening and fixing the feet. However, footwear with shoelaces has many inconveniences in wearing

For example, when the shoelaces fall off during wearing activities, the shoelaces must be re-tightened to continue activities, which often causes inconvenience and waste of time in activities

Also, wearing footwear with regular laces is potentially dangerous

For example, when the shoelaces are accidentally loosened, it is easy to cause others to step on them and trip them, and they may also be caught in the gaps of escalators, bicycle chains or motorcycle footbolts, etc., which may easily cause accidents

[0003] When wearing footwear with ordinary shoelaces, the degree of tightness of ordinary shoelaces is difficult to control, and it takes a long time to adjust, and it is easy to be too tight or too loose, which will cause discomfort to the user during wearing, and even cause fear of danger

In general, when the shoelaces are untied, the shoelaces that pass through each shoelace hole must be loosened before the user can put on and take off the shoes, which often results in a waste of time and is extremely inconvenient for the user.
