Appl. No.:

10/724279

Inventors:

Brian Jordan - Chicago IL, US

International Classification:

F16F005/00

US Classification:

267064110

Abstract:

A gas spring suspension system that adjusts the spring rate as the travel is adjusted. The suspension system includes a frame, a pressure chamber, a compression piston assembly, an adjustment assembly, a piston tube, and a shaft. The piston tube is operatively connected to the adjustment assembly and the compression piston assembly, and the compression piston assembly is configured to slidably displace along the piston tube to change the pressure in the pressure chamber. The adjustment assembly is associated with the frame and is operable to axially position the piston tube and, in turn the compression piston assembly, relative to the frame to adjust the travel of the suspension system. The shaft is configured to be variably positionable within the pressure chamber in response to axial displacement of the piston tube and the compression piston assembly by the adjustment assembly, the variable positioning of the shaft within the pressure chamber changing the pressure therein.

Abstract:

A control assembly for an in-line bicycle shock absorber can include a control member rotatably mounted to a housing of the shock absorber, the control member having an interior bore, and with one end of the bore being closed and another end of the bore being open. The control assembly also includes a piston slidably mounted within the interior bore of the control member. The control member is rotated to adjust a first characteristic of the shock absorber and the piston is displaced within the interior bore to adjust a second characteristic of the shock absorber.
