Abstract:
1. An adjustable assembly for a bicycle, comprising: a lower tubular support attached to a bicycle frame; an upper tubular support attached to a bicycle saddle extending from the frame, the upper support longitudinally slidable relative to the lower support; wherein the lower support comprises an annular expansion portion disposed on a portion of the lower support and configured to be moved between a radially expanded position and a radially contracted position, wherein an outer surface of the expansion portion is configured to engage an interior surface of the upper support when the expansion portion is in the radially expanded position; a retention assembly movably connected to the lower support adjacent the expansion portion, and configured to slidably move at least partially within or out of an interior space of the expansion portion between a locked position and an unlocked position; wherein, when the retention assembly is in the locked position, the retention assembly is moved upwards, towards the saddle, and occupies the interior space of the expansion portion to secure it in the radially expanded position, thereby preventing longitudinal movement of the upper support relative to the lower support; and wherein, when the retention assembly is in the unlocked position, the retention assembly is moved downward, away from the saddle and out of the interior space of the expansion portion, thereby allowing the upper support to move longitudinally relative to the lower support; a biasing member exerting an upward force on the retention assembly such that the expansion portion is normally resiliently biased into the locked position; a resilient member disposed above the upper end of the lower support and within the interior surface of the upper support adapted to provide an upwardly-directed force to the upper support to provide movement of the upper support away from the bicycle frame when the retention assembly is in the unlocked position; and an actuator operatively coupled to the retention assembly, the actuator being configured to selectively move the retention assembly between the locked and unlocked positions; wherein the actuator is routed to or near a bottom of the lower support.
