摘要:
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.
摘要:
A shock absorbing cushion device removable, pressure-adjustable for sports goods, comprising a cover and an air cushion enveloped in the cover, said cushion made as a hollow flat bag whose upper and lower sheets are provided and adhered with round rcesses or line recesses or the both combined, said recesses furnishing the air cushion with shock absorbing elasticity and flexibility whether said cushion is inflated or not. An inflation pump or an air nipple is provided in said cushion for inflating or deflating said cushion.

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.

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.
摘要:
An extruded tubular molding is clamped at upper and lower portions thereof to form an air-tight space therebetween and thereafter compressed within two corresponding halves of a molding die and molded into the configuration of a final product. The lower portion of the molding is first clamped and lowered to stretch the molding downwardly prior to clamping the upper portion and compressing the molding in the molding die.

摘要:
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 shock-absorbing cushion has a hollow interior possible to be filled with air, gas, liquid or semi solid to change its inner pressure, and is able to be combined with one another to be applied to sports goods, shoe soles, etc., for protecting something from pressure or shock.
摘要:
An air cushion grip with a cubic structure and shock-absorbing function to be fixed around the handle of a tennis racket, a hammer, a bicycle or the like, and comprising an outer flat layer and a bottom layer provided with a plurality of round and/or straight grooves, the vertical walls of which form a plurality of air cells which may be either independent or communicating with one another. The air cells may be inflated or deflated with an air valve or pump attached to one of the air cells for adjusting the elasticity and shock-absorbing ability of the grip.
摘要:
A vertically movable blow molding arrangement includes a whole set of molds and mold plates, two blowing needle cylinders, a set of oil spraying structures, and a conveying machine. The whole set of molds and mold plates can close or open for receiving, pinching, sealing and inflating a plastic material to shape, and moves up and down vertically between an extrusion head and the conveying machine by means of oil pressure. The whole set of molds and mold plates can automatically inflate the material without air blowing for shaping.
