摘要： A power wheel chair is disclosed having an improved motion control comprising a frame having a seat for transporting an occupant. A right and a left caster wheel are located in proximity to a front frame end. A right and a left drive wheel are located in proximity to a rear frame end. A motor drives the right and left drive wheels through a differential gearbox. A right and a left handle are connected to frame for enabling an attendant to steer the power wheel chair. An electronic control has a control lever located in proximity to one of the right and left handles for enabling the attendant to control the speed and braking of the power wheel chair.

摘要： An improved hoist is disclosed to reposition a load relative to a vehicle compartment such as a trunk of a vehicle. The hoist comprises a base for location on a generally horizontal lower surface of the vehicle compartment. A horizontal telescoping shaft has a first and second distal end extending from opposed sides of the base for engaging with opposed generally vertical surfaces of the vehicle compartment. A horizontal expander coacts between the first and second distal ends for applying a horizontal engaging force between the opposed generally vertical surfaces of the vehicle compartment for horizontally stabilizing the base within the vehicle compartment. A vertical telescoping shaft having a distal end extends vertically from the improved hoist for engaging with a upper generally horizontal surface of the vehicle compartment. A vertical expander coacts between the base surface and the distal end of the vertical telescoping shaft for applying a vertical engaging force between the lower and upper generally horizontal surfaces of the vehicle compartment for vertically stabilizing the base within the vehicle compartment. A column extends from the base for supporting a boom for repositioning the load relative to the vehicle.
摘要翻译： 公开了一种改进的起重机来重新定位相对于诸如车辆的行李箱的车厢的负载。 起重机包括用于位于车厢的大致水平的下表面上的基座。 水平伸缩轴具有从基座的相对侧延伸的第一和第二远端，用于与车厢的相对的大致垂直的表面接合。 水平膨胀器在第一和第二远端之间共同作用，用于在车厢的相对的大致垂直表面之间施加水平接合力，以水平地稳定车厢内的底座。 具有远端的垂直伸缩轴从改进的起重机垂直延伸，用于与车厢的上部大致水平的表面接合。 竖直扩展器在垂直伸缩轴的基面和远端之间共同作用，用于在车厢的下部和上部大致水平的表面之间施加垂直的接合力，用于使车厢内的基座垂直地稳定。 柱从基座延伸，用于支撑起重臂，以便相对于车辆重新定位负载。
