Patent ID: 8544855

Claim:
A skate comprising: a shoe having a sole comprising a bottom surface portion including a protrusion extending along a longitudinal axis from the bottom surface portion to a distal end of the protrusion, the protrusion including a cavity formed inwardly from the distal end and having at least one lateral recess; a detachable assembly comprising a support body and a use element, the support body comprising an upper surface portion for mating in juxtaposed contact the bottom surface portion when in an attachment position, and an associated socket formed inwardly from the upper surface for receiving in registration the protrusion when in said attachment position; and a coupling member disposed partially in the associated socket and comprising a housing fixedly secured to the support body and having an upper end sized to be received in the cavity when in said attachment position, the upper end including at least one lateral through-hole; at least one engaging member being partially disposed in and selectively movable relative to the at least one through-hole; a plunger arranged in the housing and including at least one channel sized to receive at least a partial portion of the at least one engaging member, the plunger being axially displaceable relative to the housing between a locking position whereby when in said attachment position the plunger biases the at least one engaging member radially outwardly into engagement with portions of both the housing and the at least one lateral recess to prevent the axial displacement of the protrusion relative to the associated socket, and a release position where the at least one channel is in substantial alignment with the at least one through-hole whereby when in said attachment position axial displacement of the protrusion relative to the associated socket biases the at least one engaging member radially inwardly out of engagement with the at least one lateral recess and at least partially into the at least one channel allowing for the axial displacement of the protrusion relative to the associated socket.
