Spring-loaded roller shade gudgeon

摘要

Presented is a gudgeon assembly that includes a gudgeon body, a first ball bearing, a second ball bearing, a gudgeon pin, a first spring plate, a second spring plate, and two springs. The gudgeon pin extends through the gudgeon body and is coaxial with the first and second ball bearings. The first spring plate is coupled to a distal portion of the gudgeon pin. The second spring plate defines an opening and is coupled to the second ball bearing. The opening is coaxial with the second ball bearing and the gudgeon pin. The two springs are coupled to the first spring plate and the second spring plate. Longitudinal axes of the two springs are coplanar and non-coaxial with the longitudinal axis of the gudgeon pin. The gudgeon pin, the first spring plate, and the second spring plate rotate together as a single unit and rotate independently of the gudgeon body.
