  • Patent number: 10807677
    Abstract: A directional transmission mechanism, a directional sprocket apparatus using the directional transmission mechanism, and a pedal device using the directional sprocket apparatus are disclosed. The directional transmission mechanism includes a driving shaft, an output shaft, a co-rotating wheel, a reverse-rotating wheel, and a switching mechanism. The co-rotating wheel set drives the output shaft to rotate in a direction that is the same as that of the driving shaft. The reverse-rotating wheel set drives the output shaft to rotate in a direction opposite to that of the driving shaft. The switching mechanism switches the driving shaft to drive the co-rotating wheel set or drive the reverse-rotating wheel set to rotate, so as to enable the output shaft to rotate directionally. The co-rotating wheel set is connected with the driving shaft and the output shaft, and the reverse-rotating wheel set is connected with the driving shaft and the output shaft.

    Abstract: A four wheeled, human-powered, striding cycle that uses the stepping and striding motion of the human legs to propel a rider forward. Two separate and dependent foot pedals are moved fore and aft along a concaved arc segment. The motion simulates the natural stepping and striding motion of a running human. A standing human steps on a pedal, then moves it down and aft in a striding motion. As one pedal is moved aft, the other pedal moves forward in a reciprocating fashion. A cable and pulley system connects each pedal with its respective rear wheel. Pedal motion aft applies torque to its respective drive shaft which in turn rotates its respective drive wheel. Pedal motion forward also provides torque to the opposing drive shaft creating additional torque for the opposite wheel. Forward motion begins when force is exerted down and aft on each pedal by the stepping and striding motion of the human leg.

  • Patent number: 7621547
    Abstract: 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.

  • Patent number: 7600771
    Abstract: 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.

  • Publication number: 20090058034
    Abstract: A standard-sized bicycle includes a main frame, a drive wheel and a rowing mechanism. The rowing mechanism is coupled to the main frame about a fulcrum. The fulcrum allows the rowing mechanism to oscillate forward in response to a pushing force and backward in response to a pulling force. The rowing mechanism includes a power lever and a pair of drive levers. The power lever has a handle on one end. The power lever also has a second end. The pair of drive levers extends from the second end of the power lever. Each of said pair of drive levers is in mechanical communication with the drive wheel such that both a forward oscillation of the rowing mechanism and a backward oscillation of the rowing mechanism drive the drive wheel in the same direction of rotation.

  • Patent number: 7497453
    Abstract: A reciprocal upward and downward pedaling bicycle structure includes a main shaft of a free wheel at a chain wheel shaft, a driving body pivotally coupled to a frame of the main shaft, a pedal crank and a support rod on the driving body, and a driving belt linked to the main shaft and the support rod. An end of the driving belt is dragged to the frame by a resilient element. By the action of the resilient element ands the rotation of the main shaft, the crank and pedal are pulled by the driving belt to provide an upward bounce and the chain wheel drives the rear wheel shaft through the main driving belt. When the pedal is stepped downward, the main shaft and the chain wheel are rotated synchronously to drive the rear wheel of the bicycle to move forward.
