  • Publication number: 20120126562
    Abstract: The present invention provides a modular extension device and method for mounting the modular extension device on a vehicle, such as a truck. The modular extension plate device comprises an extension plate, a left extender bracket, and potentially a right extender bracket, that when coupled together form an extension assembly. The extension plate further comprises an elongated rectangular plate having an essentially L-shaped profile, a left substantially triangle-shaped support member, a right substantially triangle-shaped support member, a left essentially L-shaped support member and a right essentially L-shaped support member. The modular extension assembly can be coupled adjacent to the rear edge of a vehicle bed for extending the depth of the vehicle bed.

  • Publication number: 20120121369
    Abstract: A lifting system includes a vertically extending parallel pair of fixedly spaced apart guide surfaces, a linear actuator suspended vertically between said pair of guide surfaces, a vertically elongate runner member having a pivotal connection to a lower end of said linear actuator to be vertically reciprocated by said actuator, a load bearing member at a lower end of said runner member at a location spaced downwardly from said pivotal connection and a vertically spaced apart pair of sliding contact members on said runner member for relatively slidable contact with said pair of guide surfaces during vertical reciprocation of said runner member by said actuator. Each of said contact members comprises a projecting contact pad having a concave surface for slidable contact with one of said guide surfaces.

  • Publication number: 20100322751
    Abstract: A lift gate system includes a lift gate assembly comprising an actuator system for actuating a lift gate, an interface device for receiving lift gate operation information from an operator, and a main controller device comprising a solid state relay switch for controlling electrical power to the actuator system. The main controller device further includes a microcontroller configured for determining that one or more conditions are satisfied, and upon satisfaction of said one or more conditions, then controlling the actuator system via the solid state relay switch based on the received information from the operator for controlling operation of the lift gate assembly accordingly.

  • Patent number: 7762756
    Abstract: The invention provides a moveable underride system that may be used with lifts such as stow lifts. The underride system includes an underride member and a linkage mechanism for coupling the underride member to a support frame, wherein the linkage mechanism moves the underride member between an extended position and a retracted position. In the extended position the underride member is at a first distance from the frame, and in the retracted position the underride is at a second distance from the frame, such that the first distance (for the extended position) is larger than the second distance (for the retracted position).

  • Publication number: 20100028115
    Abstract: A wheelchair lift having a logic module which provides several interlocks that promote proper operation is described. The logic module may be programmed to enable efficient user interface and to compensate for variations in lift operation parameters. In one embodiment, the wheelchair lift has an arm geometry which requires a lower peak force for operation.

  • Publication number: 20100002351
    Abstract: A method and apparatus is provided for controlling power to a DC load ON and OFF. The apparatus has a first FET bank, a second FET bank, connected in series with a first FET bank, and a controller. The controller is configured for detecting a operational failure of at least one of the FET banks, and turning at least on of the FET banks OFF in response, thereby turning power to the DC load OFF. The controller may also detect a operational failure of one of the FET banks, and turn the other FET bank OFF in response, thereby turning power to the DC load OFF.
