Abstract: Support is provided to the foot of a shoe wearer by an air cushion that includes a support chamber surrounding a collapsible pump operable by the foot of the wearer for directing compressed air into the support chamber and varying the firmness of the chamber. The support chamber is of a preformed three-dimensional configuration of sufficient rigidity to provide stable support to the foot prior to receiving compressed air from the pump.

Abstract: A buffer air cushion has an outer air cushion and an inner air cushion disposed in the outer air cushion. The outer air cushion is inflated with a smaller inner pressure than that of the inner air cushion so that the buffer air cushion may have better pressure elasticity and shock-absorbing functions.

Abstract: A shock-absorbing cushion comprising two sheets peripherally sealed and a plurality of half-through holes and/or grooves whose circumferential walls constitute a cubic supporting structure. The shock-absorbing cushion has a hollow interior filled with air, gas, liquid or semi-solid to change its inner pressure, and is able to be applied to sports goods, shoe soles, etc., for protecting something from pressure or shock.

Abstract: Protective air cushion gloves include hollow 3D straight air cushions for finger backs and a hand back disposed in regular rows inside the glove. Each straight air cushion has sections connected with extensible tubes and inflated with inner pressure to permit the glove to have good flexibility and an air buffer function for protecting every part of a hand, including the joints.

Abstract: Protective sports eyeglasses with a buffer being a shock-absorbing function includes a cushion having a hollow sealed endless shape. The cushion has a 3D tubular space instead of 2D (two dimensions) surface. The cushion is attached on an annular edge of a lens contacting the face of a wearer so as to fit the curvature of the face, and has an inner pressure preset in advance so that the cushion may contact closely and comfortably the face of a wearer with a buffer and a shock-absorbing effect.

Abstract: An apparatus for extrusion molding that includes an extruding die that permits extrusion of a material into a hollow tubular molding, a molding die, first and second clamping devices and a device for releasing compressed air. The first and second clamping devices are positioned along opposite end portions of the molding die and configured to clamp the molding independently from one another to form an air-tight space therebetween. The molding die includes two die cavity halves and is arranged to close around the air-tight space and compress the molding to conform the same to a final product configuration. The device for releasing compressed air is arranged to release compressed air before the die cavity halves are separated.

Abstract: An extrusion molding process including the steps of: i) extruding a material through an extruding die into a tubular molding, ii) driving two clamping devices to clamp the tubular molding at different elevations, causing an air-tight space to be formed within the tubular, iii) closing two symmetrical halves of a molding die on the molding between the clamping devices and simultaneously lowering one clamping device to stretch the molding downwards, causing the molding to be compressed in a die cavity between the two symmetrical halves of the molding die and molded into the desired finished product; and iv) opening the molding die from the finished product and returning the clamping devices to their former positions.
