Patent ID: 8453351

Claim:
A shoe with a height-adjustable heel comprising: an upper; a sole attached to the upper, the sole having a front end and a rear end; a heel configured in a position below the sole, the heel comprising: a first heel member fixedly attached to the sole rear end; an internal cavity vertically disposed within the first heel member; a hydraulic pump vertically disposed within the internal cavity, the hydraulic pump having an upper portion and a lower portion; a pump lever pivotally disposed on a rear wall of the first heel member, the pump lever having an upper end releasably disposed proximal to a top end of the hydraulic pump upper portion and a lower end; and a pivot point disposed on the pump lever lower end, the pivot point disposed proximal to a bottom end of the hydraulic pump lower portion; wherein the pump lever has an extended position and an alternate retracted position; wherein the pump lever is in operational communication with the hydraulic pump; an elongated cylindrical second heel member telescopically disposed within the first heel member internal cavity, the second heel member having a proximal end and a distal end; wherein the hydraulic pump lower portion is centrally slidingly disposed within the second heel member; a heel tip attached to the second heel member distal end; and a twist-lock valve mechanism disposed within the heel tip; wherein the twist-lock valve mechanism has an open position and an alternate closed position; wherein, in the open position, the twist-lock valve mechanism permits the passage of an amount of air into the hydraulic pump; wherein, in the closed position, the twist-lock valve mechanism prevents the passage of the air into the hydraulic pump; wherein the activation of the pump lever in an extended position with the twist-lock valve mechanism in the open position activates the hydraulic pump; wherein the activation of the hydraulic pump selectively extends the second heel member into a partially raised position and an alternate raised position, whereby the heel is lengthened; wherein the deactivation of the pump lever in a retracted position deactivates the hydraulic pump; and wherein the deactivation of the hydraulic pump selectively retracts the second heel member into a lowered position, whereby the heel is shortened.
