Abstract

A three dimensional shoe vamp air cushion having an upper sheet and a lower sheet, with all peripheral edges sealed to form a hollow interior. An upper area of the air cushion is larger than the interior area, permitting the air cushion body to have three dimensions instead of two dimensions. The three dimensional shoe vamp air cushion has one or more air chambers and a similar curvature as the upper surface of a foot, so as to have excellent adaptability and shock absorbing characteristics.

Claims

1. A three dimensional shoe vamp air cushion comprising

a curved upper sheet and a curved lower sheet,

a hollow interior formed between sealed peripheral edges of said lower sheet and said upper sheet, said hollow interior being defined between two opposed side edges and two opposed ends,

said sheets each having lengthwise surfaces shaped so as to be both curving inwardly, and

said upper sheet and said lower sheet being continuously smooth surfaces between said side edges and said two opposed ends, each having cross-sections of curved lines,

a surface area of said upper sheet being larger than a surface area of said lower sheet.

2. The three dimensional shoe vamp air cushion as claimed in claim 1, wherein said air cushion is provided with a hollow passageway for attachment to one of an air valve or an air pump communicating with ambient air for inflating said air cushion.

3. The three dimensional shoe vamp air cushion as claimed in claim 1, wherein a layer of soft material disposed between said upper sheet and said lower sheet is selected from the group consisting of fiber and foam.

4. A three dimensional shoe vamp air cushion comprising

an upper sheet and a lower sheet having all peripheral edges sealed to form a hollow interior and including longitudinally extending peripheral side edges,

said sheets forming two lengthwise surfaces extending to form a curved inward air cushion, and said upper sheet and said lower sheet each having cross-sections of curved lines,

a plurality of recessed depressions extending inwardly from at least one of the upper sheet and the lower sheet, the recessed depressions extending widthwise entirely across the air cushion until reaching the longitudinally extending peripheral side edges.

5. The three dimensional shoe vamp air cushion as claimed in claim 4, wherein said air cushion is provided with a hollow passageway for attachment to one of an air valve or an air pump communicating with ambient air for inflating said air cushion.

6. A three dimensional shoe vamp air cushion comprising

an upper sheet and a lower sheet having a hollow interior therebetween and including longitudinally extending peripheral side edges,

said sheets forming two lengthwise surfaces extending in the form of an inward curved air cushion,

said upper sheet and said lower sheet each having cross-sections of curved lines, and

at least one of said upper sheet and said lower sheet being provided with a plurality of depressions selected from the group consisting of recessed lines and recessed holes,

the recessed lines extending inwardly from at least one of the upper sheet and the lower sheet, the recessed lines extending widthwise entirely across the air cushion until reaching the longitudinally extending peripheral side edges,

the recessed holes extending inwardly from at least one of the upper sheet and the lower sheet, the recessed holes defining cylindrical shaped depressions.

7. The three dimensional shoe vamp air cushion as claimed in claim 6, wherein said air cushion is provided with a hollow passageway for attachment to one of an air valve or an air pump communicating with ambient air for inflating said air cushion.

8. A three dimensional shoe vamp air cushion comprising

an upper sheet and a lower sheet,

a layer of soft material located in a hollow interior formed between said upper sheet and said lower sheet and attached between said sheets,

said sheets each having lengthwise surfaces shaped so as to be curving inwardly, and

said upper sheet and said lower sheet each having cross-sections of curved lines,

at least one of said upper sheet and said lower sheet being provided with a plurality of depressions selected from the group consisting of recessed lines and recessed holes,

the recessed lines extending inwardly from at least one of the upper sheet and the lower sheet, the recessed lines extending widthwise entirely across the air cushion until reaching longitudinally extending peripheral side edges,

the recessed holes extending inwardly from at least one of the upper sheet and the lower sheet, the recessed holes defining cylindrical shaped depressions.

9. The three dimensional shoe vamp air cushion as claimed in claim 8, wherein said air cushion is provided with a hollow passageway for attachment to one of an air valve or an air pump communicating with ambient air for inflating said air cushion.

10. A three dimensional shoe vamp air cushion comprising

an upper sheet and a lower sheet having a hollow interior therebetween, an upper area of said upper sheet being larger than an inner hollow area of said lower sheet,

said sheets forming two lengthwise surfaces extending in the form of an inward curved air cushion,

said upper sheet and said lower sheet each having cross-sections of curved lines, and

at least one of said upper sheet and said lower sheet being provided with a plurality of depressions selected from the group consisting of recessed lines and recessed holes,

the recessed lines extending inwardly from at least one of the upper sheet and the lower sheet, the recessed lines extending widthwise entirely across the air cushion until reaching longitudinally extending peripheral side edges,

the recessed holes extending inwardly from at least one of the upper sheet and the lower sheet, the recessed holes defining cylindrical shaped depressions.

11. The three dimensional shoe vamp air cushion as claimed in claim 10, wherein said air cushion is provided with a hollow passageway for attachment to one of an air valve or an air pump communicating with ambient air for inflating said air cushion.
