Abstract
A flexible pad body includes an inflatable part that is compressible and that confines a cavity injected with high pressure gas such that the pressure in the cavity is greater than the ambient pressure, and at least a discharging valve installed in the inflatable part and having a valve opening for permitting fluid communication between the cavity and the atmosphere. The discharging valve is deformable in such a manner that when foot pressure is applied on the pad body, the discharging valve is deformed, which, in turn, results in opening of the valve opening, and that when the pad body is relieved from the foot pressure, the discharging valve recovers to its non-deformed state, which, in turn, results in closing of the valve opening.
Claims6
A shoe pad comprising:
- a flexible pad body including an airtight flat inflatable part that is compressible and that confines a cavity adapted to store a high pressure gas therein in such a manner that the pressure in said cavity is greater than the ambient pressure so as to permit discharge of the gas from said cavity into the atmosphere;
- and
- at least a discharging valve installed in said inflatable part and including a valve body that has a valve opening for permitting fluid communication between said cavity and the atmosphere, said discharging valve being deformable in such a manner that when foot pressure is applied on said pad body, said discharging valve is deformed, which, in turn, results in opening of said valve opening, thereby permitting the discharge of the gas from said cavity into the atmosphere, and that when said pad body is relieved from the foot pressure, said discharging valve recovers to its non-deformed state, which, in turn, results in closing of said valve opening, thereby preventing the discharge of the gas from said cavity into the atmosphere.
