Pneumatic elastic band and its applicable inflation system

Abstract

An air pressure type elastic band comprises an outer layer, an inflatable part and an air nozzle. The outer layer is a strip-shaped elastic structure. The inflatable part is disposed in the outer layer, and includes several expansion parts and several communication parts, each communication part is connected between adjacent expansion parts and defines several gaps. The air nozzle is arranged on the surface of the outer layer and communicated with the inflatable part. By introducing gas into the inflatable part through the air nozzle, several inflatable parts of the inflatable part are inflated and compressed inwardly, thereby fastening the shoes; by leading the gas into the inflatable part through the air nozzle, the inflatable part is deflated and returned to its original state. In the uninflated state, use it to tie loose shoes.

Description

Technical field[0001]The present invention relates to a pneumatic elastic strip and a permeable system thereof, particularly an inflatable pneumatic elastic band and an inflatable system thereof.Background technique[0002]In general, most of the traditional footwear is a tool with a general shoe as a loose and fixed foot, however, there will be many unemployed on the foot of the lace. For example, when wearing the activity, the lace is falling off, and the lace must be re-tight to continue the activities, often cause waste of the inconvenience and time. In addition, wearing shoes with general laces also have potential hazards. For example, when the lace is inadvertently released, it is easy to cause others to step on, and it is possible to be involved in the gap of the automatic elevator, bicycle chain or motorcycle pins, etc., which is easy to cause unexpected occurrence.[0003]When wearing a footwear with general laces, the tightness of the general lace is not easy to control, and i...

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 and trip, and it may also be involved 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

And generally, when the shoelaces are untied, part of the shoelaces that pass through each shoelace hole must be loosened first 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.
