Anti-fall pneumatic system for fixing shoes

Abstract

The invention discloses an anti-fall pneumatic system for fixing shoes. The system comprises a microcomputer, a pressure pump, a pressure sensor, a leakage stopping / reducing valve, a switch set, an air bag, a voltage stabilizing circuit and a battery and is mounted in a shoe. When the shoe is worn on a foot, a switch is turned on to drive the microcomputer to control the pressure pump to move so as to inflate the air bag, the space between the air bag and the shoe is expanded, and the shoe in fixedly arranged on the foot by virtue of a mutual friction force; and when the shoe is taken off, the air bag is controlled to exhaust, and the shoe can be taken off through the slight movement of the foot. According to the anti-fall pneumatic system, the shoes do not need to be designed with shoelaces, so that the problems that the shoelaces are difficult to loosen and tie in the prior art are well solved, the shoes can be automatically fastened and loosened and are convenient to wear and take off and good in comfortableness.

Description

technical field [0001] The present invention relates to a pneumatic system for fixing and preventing shoes from falling off, especially a special system for fast wearing and convenient tightening of shoes. Background technique [0002] There are various types of shoes sold on the market now, such as casual shoes, sports shoes, sandals and leather shoes, etc., the main way for the existing shoes to be fixed on the feet is to have rope shoelaces, so that the people who wear shoes will The shoes are firmly fixed on the feet, which is convenient for the wearer to walk or run without falling off; [0003] As for rope shoelaces, the biggest disadvantage of this method is that shoelaces are difficult to tie (difficult to loosen and difficult to tie tightly), especially for preschool children aged 3-7, elderly people with inflexible hands and feet, disabled people, etc. It is difficult to carry out this kind of tethered shoelaces. For example, it is difficult for children to put on...

[0003] As for rope shoelaces, the biggest disadvantage of this method is that shoelaces are difficult to tie (difficult to loosen and difficult to tie tightly), especially for preschool children aged 3-7, elderly people with inflexible hands and feet, disabled people, etc. It is difficult to carry out this kind of tethered shoelaces. For example, it is difficult for children to put on and take off their shoes. In addition, the shoelaces are easy to loosen. The loosened shoelaces may cause children or the elderly to step on them while walking or running. , leading to safety hazards such as children falling
