Abstract

This invention provides an inexpensive and reliable air supply system, a multi-purpose air filling structure for various protective gear and equipment, using a general-purpose standard valve that can be easily implemented in a variety of protective gear and equipment. [Solution] A snap-in valve 10 for vehicle tires, which is widely used worldwide, is repurposed as an air chamber for shock absorption and fixed using the elastic deformation of the material. This makes it possible to adjust the internal air pressure via the valve from an external general-purpose air supply source 30. Furthermore, the opening edge 21 of the air chamber 20 has a smaller diameter than the groove diameter of the valve, and by pulling the valve from the inside to the outside when it is installed, the elastic restoring force of the valve maintains airtightness, thus achieving both easy pressure adjustment and high airtightness.

Claims

1. An air-filled structure for an impact absorber or cushion having an air chamber, characterized by being equipped with a snap-in valve for vehicle tires conforming to JIS or ISO standards, wherein the opening edge of the air chamber elastically fits into the fixing groove of the valve, and the internal air pressure can be adjusted via the valve from an external general-purpose air supply source.

2. The air-filling structure according to claim 1, characterized in that the opening edge of the air chamber has a diameter smaller than the groove diameter of the valve, and the valve is installed by being pulled from the inside to the outside, thereby maintaining airtightness by the elastic restoring force of the valve.
