Abstract
The present application discloses a method for fabricating a composite structure for use as a resilient cushion, including: (a) placing a sheet of first resilient material on a surface; (b) cutting the sheet of first resilient material by pressing a cutter on to the first resilient material to produce a cut sheet of first resilient material displaying a cutting pattern of discrete first resilient elements of defined widths and lengths, wherein at least one of the first resilient elements touches adjacent resilient elements along its side; and (c) mounting a first expanse of material on at least one of the first resilient elements of the cut sheet of first resilient material to form a first composite structure.
Claims16
A composite material of a cushion on bottom of a footwear, comprising a sheet of resilient material comprising:
- a first expanse of material on the bottom of the footwear to which it is bound;
- and
- a plurality of resilient elements having defined length and width and physical characteristics, wherein each resilient element is directly bound to the first expanse of material at one end, wherein the resilient elements are spaced apart from each other, wherein the resilient elements are comprised of any one of ethylene vinyl acetate (“EVA”) foam, olefin or polyolefin foam, polyurethane (“PU”) foam, urethane based foam, or thermoplastic foam, wherein at least one of the plurality of resilient elements is different from at least one of the remainder of the plurality of elements in physical characteristics, wherein a free end of the resilient elements face away from the footwear, wherein the resilient elements comprise a dense material of EVA foam, fully or partially enveloped by less dense material.
A multiple density composite material of a resilient cushion on bottom a footwear, comprising:
- (i) a first expanse of material;
- and
- (ii) a plurality of resilient elements having defined first end and second end and a middle along the length of the resilient element, as well as defined width along the length of the resilient element, wherein each resilient element is directly bound to the first expanse of material at the first end of the resilient element and free of binding at the second end to form the composite material, wherein the first end of the resilient element connected to the first expanse of material has maximum diameter that is less than the maximum diameter of the middle of the resilient element, wherein the resilient elements are spaced apart from each other, wherein the resilient elements are comprised of any one of ethylene vinyl acetate (“EVA”) foam, olefin or polyolefin foam, polyurethane (“PU”) foam, urethane based foam, or thermoplastic foam, wherein at least one of the plurality of resilient elements is different from at least one of the remainder of the plurality of elements in physical characteristics, wherein the resilient elements comprise a dense material of EVA foam, fully or partially enveloped by less dense material.
