- The present invention relates to an air cushion assembly adapted for absorbing heel impacts in a shoe mid-sole and in particular, to an air cushion assembly having an air bladder associated with a cushioning element in a vertical stack configuration that capable of absorbing more than one range of heel impacts against the ground.
- For most runners, initial foot impact occurs in the heel region. Therefore, the heel strike cushioning material, which is contained principally in the mid-sole of a running shoe, must have a firmness which provides for proper impact cushioning for a person of about average weight.
- U.S. Design Pat. No. 297,980 to Sugiyama describes a cushioning for a shoe mid-sole comprised essentially of one cell having partition walls therein.
- U.S. Pat. Nos. 4,342,157 and 4,472,890 to Gilbert describes the use of liquid-filled shock absorbing cushions in the heel portion and forefoot portion of a shoe. Typical liquids include water, glycerin, and mineral oil.
- When the runner is heavy, the heel cushioning material may “bottom out” before heel impact is completely absorbed, and shock-related injuries can result. On the other hand, if the cushioning material is too soft poor lateral foot stability may result in injuries.
- A considerable forces generated during athletic activities require that the sole of an athletic shoe provide enhanced protection and shock absorption for the feet, ankles and legs of the wearer. For example, impacts which occur during walking have been known to generate forces of up to 1-½ times the body weight at normal walking speed, running activities up to 2-3 times the body weight of an individual.
- For providing an air cushion with wider range of impact absorption, an easier conventional fabrication method of air cushion is shown in
FIG. 1 , including the steps of preparing alarger bladder 1, putting thelarger bladder 1 in a hotpressing mold 13 for forming a plurality ofribs 11 which divides the larger bladder intosmaller bladders - However, the total cushioning area of the
smaller bladders larger bladder 1, and theribs 11 form a plurality ofvertical walls 110 around each of thesmall bladders smaller bladders 14 in the central portion become bottom out under some heavy heel impact. - The
smaller bladder 14 in central area can be made softer to comfort the heel of the wearer during taking a normal walking exercise; however this would cause thesmaller bladder 14 tends to bottom out in normal running activity. If thesmaller bladder 14 contains a higher inner pressure to provide adequate shock absorption for running, it would cause the wearer feels it is too hard and suffers a pain from thebladder 14 in a normal walking. - In order to perfect the heel cushion in different athletic activities, such as walking and running, there is a need to improve the cushioning function at shoe mid-sole.
- In order to perfect the heel cushioning design for athletic activities, the present invention provides an air cushion assembly and a fabrication method for producing such a cushion assembly. The air cushion assembly according to the present invention contains an air bladder associated with a cushioning element in a vertical stack configuration, so as to absorb a lighter heel impact and heavier heel impact sequentially.
- The air bladder of the air cushion assembly may contain a lower inner pressure for providing a softer shock absorption during a wearer taking walking exercise, and the cushioning element may be an air bladder with higher inner pressure or a cushion which made from a resilient element for absorbing some other heavier heel impacts, such as running or playing ball, or the likes.
- The fabrication method of the present invention may include the steps of blowing a melting inflatable bladder or tube together with a cushioning element in a blowing mold, inflating the melting inflatable bladder with air in high pressure, so as to form a bladder with a passage way that confirming the inner shape of the blowing mold, and blowing air into the bladder in a preset inner pressure; and thereafter sealing the passage way for forming an air cushion with multistage shock-absorbing assembly.
