Patent number: 7621547Abstract: A scooter propulsion mechanism includes a pedal secured to the upper surface of the platform and a rigid link pivotally connected from the pedal to the mechanism components mounted on the bottom surface of the platform. Approximately one-half of the propulsion mechanism is located at one side of the rear wheel, and the other one-half is located at the other side of the rear wheel. The mechanism in one embodiment includes a plurality of gear wheels to increase rotational speed, and in another embodiment a plurality of sprocket wheels joined by chain loops, in both cases to drive the rear wheel and propel the scooter. A slot in the platform allows the larger sprocket wheels or gear wheels to project upwardly therethrough, so that there is sufficient ground clearance for safe riding.Type: GrantFiled: July 24, 2006Date of Patent: November 24, 2009Inventor: Ronnie Chee Keung Fan

Patent number: 7600771Abstract: Drivetrains and frames for vehicles, equipment, machines, etc. Some embodiments of the drivetrains and frames are particularly suited for human powered machines, such as bicycles and exercise equipment. In some embodiments, a drivetrain includes a reciprocating crank coupled to a crank pivot. A lever couples to the crank via a lever pivot positioned on the crank. A lever stop cooperates with a lever guide surface to guide a motion of the lever as the lever pivots about the lever pivot. The lever and/or the crank are operably coupled to a drive pulley, idler pulley, and/or compound pulley. In some embodiments, a drive cable operably couples the lever and/or the crank to the drive pulley, idler pulley, and/or the compound pulley. In one embodiment, one or more pulleys couple to the lever's distal ends. In some embodiments, the drivetrain includes a wheel hub adapted to receive torque from the crank via a drive pulley.Type: GrantFiled: December 6, 2007Date of Patent: October 13, 2009Assignee: Catadon Systems LLCInventors: Donald C Miller, Michael C Ross
