ADJUSTABLE SADDLE POST SYSTEM

摘要

An adjustable length post for a bicycle comprises first and second slidably coupled supports, the second support comprising an interior cavity defined by an interior surface, the interior surface having a portion recessed from a surrounding surface; and a collet coupled to or integrated into the first support, the collet comprising a body positioned at least partially within the interior cavity of the second support; a locking member pivotally or slidably coupled to the body, the locking member repositionable between a locked configuration and an unlocked configuration, wherein, in the locked configuration, the locking member protrudes laterally from the body an amount sufficient to engage the recessed portion of the interior surface of the second support, and, in the unlocked configuration, the locking member does not protrude laterally from the body or does not protrude an amount sufficient to engage the recessed portion of the interior surface of the second support.

主权项

1. An adjustable length post for a bicycle, the adjustable length post comprising:
first and second slidably coupled supports, the second support comprising an interior cavity defined by an interior surface, the interior surface having a portion recessed from a surrounding surface; and a collet coupled to or integrated into the first support, the collet comprising:
a body positioned at least partially within the interior cavity of the second support;a locking member pivotally or slidably coupled to the body, the locking member repositionable between a locked configuration and an unlocked configuration,wherein, in the locked configuration, the locking member protrudes laterally from the body an amount sufficient to engage the recessed portion of the interior surface of the second support, and, in the unlocked configuration, the locking member does not protrude laterally from the body or does not protrude an amount sufficient to engage the recessed portion of the interior surface of the second support;an actuating member positionable to engage an inner surface of the locking member to selectively retain the locking member in the locked configuration; anda piston coupled to the second support and configured to cause sliding of the second support with respect to the first support,wherein the piston is compliantly coupled to the second support, such that, when the second support is in a fully extended position with respect to the first support, movement of the piston with respect to the first support and second support causes the actuating member of the collet to retain the locking member in the locked configuration.
