Patent ID: 8702336

Claim:
An adjustable assembly for a bicycle, comprising: a first tubular support having an interior surface; a second tubular support positioned within the first tubular support and slidably movable relative to the first tubular support along a longitudinal axis of said first and second tubular supports, said second tubular support being adjacent to at least a portion of the interior surface of the first support; wherein one of the first support and the second support is adapted to attach to a first bicycle portion, and wherein the other of the first support and the second support is adapted to attach to a second bicycle portion; wherein the second support comprises an expansion portion, wherein the expansion portion is selectively movable between a radially expanded position and a radially retracted position, wherein an outer surface of the expansion portion lockingly engages at least a portion of the interior surface of the first support when the expansion portion is in the radially expanded position; a retention assembly movable relative to the expansion portion, said retention assembly being selectively movable between a locked position and an unlocked position; wherein, when the retention assembly is in the locked position, said retention assembly prevents the expansion portion from moving from the radially expanded position to the radially retracted position, thereby preventing said second tubular support from moving upward relative said first tubular support and preventing said second tubular support from moving downward relative said first tubular support; a biasing assembly exerting an upwardly-directed force on the expansion portion; a resilient member exerting a downwardly-directed force on the retention assembly in a direction generally opposite of the upwardly-directed force created by the biasing assembly, wherein the retention assembly is normally biased in the locked position; and a connector operatively coupled to the retention assembly, whereby movement of the connector by a user selectively moves the retention assembly between the locked and unlocked positions.
