  • Publication number: 20090081012
    Abstract: A system is provided for securing lift gate including a first rack bracket, a second rack bracket, a first gate bracket, a second gate bracket, a rod bracket and a rod assembly. A method for securing lift gate includes the steps of grasping a lift gate; applying force to the lift gate sufficient to move the lift gate towards its closed position and, as chamfers of rod ends engage rack brackets, sufficient to compress a spring thereby moving the rod ends and moving a rod assembly within rod holes and thereby allowing the rod ends to align with and insert into the rod slots; In opening the lift gate, applying force to a handle sufficient to compress the spring thereby moving the rod ends and moving the rod assembly within the rod holes and withdrawing the rod ends from the rod slots; and applying force to the lift gate thereby moving the lift gate towards its open position.

  • Patent number: 6845829
    Abstract: A utility vehicle with foot-controlled mobility is provided that includes a skeletal frame structure supporting a gasoline engine which utilizes a belt drive system to drive hydraulic motors with one hydraulic motor disposed at each rear wheel. The vehicle includes four wheel and tire assemblies, substantially at each corner with the rear wheels being driven and the front wheels being formed as casters for 360° rotation to provide a zero turning radius vehicle. The user sits upright in a manner wherein the user's legs are supported on pivotal leg support plates to allow the user to sit upright with legs directed down and away from the waist to allow the user to operate a hand-held implement. Both speed control and directional control are provided using pivotally mounted pedals with one pedal controlling each hydraulic motor. Movement of the pedals allows individual motor control to provide drive steering and speed control.
