Adjustable assembly for bicycles and methods of using same

摘要

An adjustable assembly for a bicycle includes a first support having an interior surface and a second support slidably positioned within at least a portion of the first support. One of the first support and the second support is adapted to attach to a first bicycle portion, and the other of the first support and the second support is adapted to attach to a second bicycle portion. Further, the second support comprises an expansion portion configured to be moved between an expanded position and a retracted position. The expansion portion is configured to engage the interior surface of the first support when the expansion portion is in an expanded position. In addition, the first support is configured to be selectively moved relative to the second support when the expansion portion is permitted to assume a retracted position.

主权项

1. A method of adjusting the vertical position of a bicycle component, comprising:
securing an adjustable assembly to a bicycle, the assembly comprising:
a first support;a second support slidably movable relative to the first support, the second support comprising an expansion portion within the first support and configured to engage at least an inner surface of the first support when the expansion portion is in an expanded position;a biasing assembly configured to urge the first support away from the second support; andan actuator configured to selectively permit the expansion portion to be either in (i) a locked orientation wherein the expansion portion is maintained in the expanded position, or (ii) an unlocked orientation wherein the expansion portion is generally allowed to move into a retracted position, wherein the expansion portion is normally biased into the locked orientation by the actuator;wherein the first support is configured to be slidably moved relative to the second support when the expansion portion is in the unlocked orientation;wherein the first support is configured to be generally stationary relative to the second support when the expansion portion is in the locked orientation; wherein the first support is secured to a first bicycle portion; and
wherein the second support is secured to a second bicycle portion; selectively raising the second bicycle portion relative to the first bicycle portion by reducing downward forces on the second bicycle portion and moving the actuator so that the expansion portion is in the unlocked orientation, or selectively lowering the second bicycle portion relative to the first bicycle portion by exerting a downward force on the second bicycle portion and moving the actuator so that the expansion portion is in the unlocked orientation; and maintaining a selected vertical position of the first bicycle portion relative to the second bicycle portion by moving the actuator so that the expansion portion is in the locked orientation; wherein the first support is configured to be slidably moved relative to the second support while a bicycle is being ridden.
