VALVE STRUCTURE AND FLEXIBLE INFLATABLE MEMBER PROVIDED WITH THE VALVE STRUCTURE

摘要

A valve structure provided in the interior space of a flexible inflatable member for maintaining an air-tight seal of the interior space of the flexible inflatable member and for forcing gas into or out of the interior space of the flexible inflatable member without making contact with a valve portion, and a flexible inflatable member provided with the valve structure are provided. The valve structure is fixed to a flexible inflatable body so as to constitute a flexible inflatable member. A valve structure is installed in the interior space of the flexible inflatable body so as to force air into or out of the interior space while maintaining air-tight seal of the interior space. The valve structure includes a cylindrical-shaped valve body in which one end thereof is blocked with a predetermined thickness and the other end thereof is opened; a valve portion in which the thickness of the blocked portion of the one end is incised from an outer surface of the one end to the inner surface on the interior space side of the valve body, and one of confronting surfaces of the incision is movable in the longitudinal direction of the cylindrical-shaped valve body; and an uplifted portion which protrudes from one side of the incision toward the interior space. When the uplifted portion is pressed in the longitudinal direction of the valve body, the one of the confronting surfaces of the incision of the valve portion being in close contact is moved so as to allow a space on the outer surface side of the blocked portion to communicate with the interior space S of the valve body.
