Abstract
Abstract A pneumatic inflating device disposed within the sole of a shoe includes a plurality of pairs of oppositely disposed hollow chambers within the sole of the shoe, a plurality of inflatable air cells, each air cell disposed within one of said hollow chambers, a pump assembly attached to the shoe, a plurality of tubes connecting the air cells to the pump assembly, means for restricting air flow out of the air cells, and means for releasing air from the pneumatic inflating device. The means for restricting air flow out of the air cells includes a nipple disposed at the end of each branch of the tubes. The means for releasing air from the pneumatic inflating device includes a release valve. The pneumatic inflating device can further include means for locking the pump assembly in a closed position.

Claim 2
Dependent Claim
86 words
A pneumatic inflating device disposed within the sole of a shoe, said pneumatic inflating device including: a plurality of pairs of oppositely disposed hollow chambers within the sole of the shoe; a plurality of inflatable air cells, each air cell disposed within one of said hollow chambers; a pump assembly attached to the shoe; a plurality of tubes connecting said air cells to said pump assembly; means for restricting air flow out of said air cells; and means for releasing air from said pneumatic inflating device.
Claim 3
Dependent Claim
20 words
A pneumatic inflating device as in claim 1 further including means for locking said pump assembly in a closed position.
Claim 4
Dependent Claim
68 words
A pneumatic inflating device as in claim 2 wherein said means for locking said pump assembly in a closed position includes a first pair of flanges disposed on a head of said plunger and a second pair of flanges disposed on said housing whereby when said head is rotated, the first pair of flanges are disposed below the second pair of flanges thereby locking said plunger in position.

Claim 7
Dependent Claim
32 words
A pneumatic inflating device as in claim 1 wherein said means for restricting air flow out of said air cells includes a nipple disposed at the end of each of said tubes.
Claim 8
Dependent Claim
24 words
A pneumatic inflating device as in claim 1 wherein said means for releasing air out of said air cells is a release valve assembly.
Claim 9
Dependent Claim
19 words
A pneumatic inflating device as in claim 1 wherein said air cells are made from a rubber based product.
Claim 10
Dependent Claim
26 words
