International Classification:
B62M 100
US Classification:
280 87041, 280 8705
Abstract:
A scooter has a plurality of wheels, a steerer, a platform, and a steerer support. The steerer support connects the steerer to the platform. The steerer support can rotate with respect to the platform, allowing the scooter to be folded when not in use. The steerer support can nest within the platform, further allowing the scooter to collapse into a compact position. The steering axis, front wheel diameter, and fork geometry are arranged to provide stable steering. Specifically, the steering axis and the front wheel axis of rotation are both located aft of the centerline of the steerer. Further, the contact point between the front wheel and the ground and the axis about which the front wheel rotates are located aft of the steering axis about which the steerer rotates. The trail, measured between the steering axis and the front wheel contact point, is kept relatively small, between 0 and 75 mm. Also disclosed is a collapsing steerer, a parallel-rail support structure, and a compact braking element.

International Classification:
S63B 21005
US Classification:
482115
Abstract:
A passive exercise apparatus includes an interface member for coupling to a user's limb. An arm member is coupled to the interface member by a wrist joint. The wrist joint has rotational motion about three axes. A first link is coupled to the arm member by a sliding joint. The sliding joint allows translational motion of the arm member relative to the first link. A second link is rotatably coupled to the first link by a first rotary joint. A third link is rotatably coupled to the second link by a second rotary joint. A first brake is coupled to the first rotary joint for resisting movement of the first rotary joint. A second brake is coupled to the second rotary joint for resisting movement of the second rotary joint. A third brake is coupled to the arm member for resisting movement of the arm member. The user is capable of interfacing with the apparatus to exercise a six degree of freedom motion.
