摘要： A tiller assembly for steering a personal mobility vehicle. A knuckle joint for the tiller includes a base secured on the front wheel steering spindle and a knuckle element connected for limited pivotal movement on the base. A bolt connects the knuckle element to the base and also connects the tiller to the knuckle joint. A spring loaded pin on the tiller enters spaced apart openings in the knuckle element to lock the tiller to the knuckle element in any one of various positions, including an operating position and a collapsed position. Adjustment screws on the base are contacted by stop surfaces on the knuckle element to limit in both directions the pivoting of the knuckle element. This allows the tiller to float to a limited extent and also to act rigidly when the vehicle user needs to pull himself up by using the tiller. Spacer sleeves on the pivot bolt allow adjustment of the friction between the knuckle element and base without affecting the tiller.
摘要翻译： 用于转向个人行动车辆的耕耘机组件。 用于耕耘机的转向节接头包括固定在前轮转向主轴上的基座和连接在底座上用于有限的枢转运动的转向节元件。 螺栓将转向节元件连接到基座，并将耕作机连接到转向节。 耕耘机上的弹簧加载销在转向节元件中进入间隔开的开口，以将耕耘机锁定到转向节元件中，其中包括操作位置和收缩位置的各种位置中的任何一个。 底座上的调节螺钉与关节元件上的止动表面接触，以限制转向节元件的两个方向的转动。 这允许耕耘机在有限的程度上浮动，并且当车辆用户需要通过使用耕耘机将其自己拉起时，也能够刚性地行动。 枢轴螺栓上的间隔套筒允许调节转向节元件和基座之间的摩擦而不影响耕耘机。

摘要： A powered wheelchair for disabled persons is provided that has a frame that has a first end and a second end. A seat support is coupled to the frame between the first and second ends. A pair of swivel wheels is coupled to the frame proximate the first end and a pair of motor driven wheels is connected to the frame proximate the second end. A motor is coupled to each of the driven wheels. The motors are adapted to allow a change in the rotational direction of the driven wheel to which it is coupled, wherein the rotational direction of the motors may be changed when the wheelchair is converted from a rear wheel drive wheelchair to a front wheel drive wheelchair. At least one battery is coupled to the motors, the battery providing power to the motors. An electronic controller is coupled to the motors and the battery. The controller has a user interface that is used to direct the speed and direction of the wheelchair. A seat assembly is reversibly coupled to the seat support and extends upwardly above the frame. The seat assembly has an extension member coupled thereto that is adapted to be reversed in direction relative to the seat support. The seat assembly further includes a seat base having a front edge. The seat base may thus be located so that the front edge is located generally over the swivel wheels to provide a rear wheel drive wheelchair and may be reversed so that the front edge is located generally over the driven wheels to provide a front wheel drive wheelchair. The rotational direction of the driven wheels may be reversed so that a forward command from the controller results in a different rotation when the wheelchair is in a rear wheel drive configuration as compared to a forward command when the wheelchair is in a front wheel drive configuration.

摘要： A powered wheelchair for disabled persons is provided that has a center frame that has a first end and a second end. The wheelchair further has a seat support coupled to the center frame between the first and second ends. A pair of rear stabilizing wheels is connected to the center frame near the first end. The wheelchair further includes a drive assembly that is removably coupled to the center frame near the second end. The drive assembly has a pair of drive wheels that each have a motor operably connected thereto. A coupling mechanism is associated with the frame and the drive assembly that removably couples the frame to the drive assembly. The coupling mechanism is applicable and releasable by hand without the use of any tools. A power source is removably held on the center frame generally between the first and second ends, and is electrically connected to each of the motors. A seat assembly is removably coupled to the seat support that extends upwardly above the center frame. Finally, a controller is provided that allows operation of the drive assembly to be controlled. The controller is removably coupled to the seat assembly.
