  • Angle adjustment assembly
    Patent number: 10085903
    Abstract: An angle adjustment assembly comprises a first member configured to pivot about a first axis. A second member is configured to rotate about a second axis transverse to the first axis. The first member is eccentrically supported in relation to the second member so that rotation of the second member produces pivotal movement of the first member. A third member may be configured to rotate about a third axis transverse to the first axis. The second member may be eccentrically supported in relation to the third member so that rotation of the third member further produces pivotal movement of the first member. The second member may comprise an inner cam member. The third member may comprise an outer cam member. The first member may be a caster stem for supporting a wheelchair caster assembly, or alternatively, an axle receiver for supporting an axle of a wheelchair drive wheel.
