  • Patent number: 4570739
    Abstract: A personal mobility vehicle includes a floor pan with a rear drive unit at one end and a steerable front wheel at the other end. The drive unit is separable from the floor pan and includes spaced apart, differentially connected rear wheels, an electric motor, and belts and pulleys drivingly connecting the motor to a differential unit. The front wheel is steered by a tiller. A seat with a folding back is removably connected to the floor pan toward the pan rear end to concentrate the weight of the driver over the rear wheels to aid in traction. A brake is provided on the front wheel and is lockable for parking purposes. Each of the drive unit, seat unit, a battery, and a floor pan unit weighs less than thirty pounds such that the separated components can be easily lifted and manipulated for transportation of the vehicle between sites of use.

  • Patent number: 4538695
    Abstract: A self propelled two speed vehicle suitable for use as a golf cart, in which the frame is arranged to carry one or two golfers and/or their golf clubs over short distances such as are encountered in golf course use. The cart is provided with a low level flat rearwardly directed riding platform applied between the two rear wheels of the vehicle which enables one or two persons to ride the scooter by standing on the platform, in side by side relation where two persons are to ride the vehicle, with the vehicle frame and platform being arranged for ease of mounting and dismounting same by stepping up or stepping down from the rear of the vehicle. The vehicle has a single foot actuated control lever for actuating or stopping the vehicle, and a steering wheel for steering the vehicle front wheel, which control lever and steering wheel are centered so that a rider standing in either the right or left side positions on the riding platform can operate the scooter vehicle.

  • Patent number: 4538696
    Abstract: A battery powered golf club cart having an elongated handle which controls both the power applied to its rear wheels and a brake associated with its front wheel. When the handle is depressed an electric motor which rotates the rear wheels is actuated and the front brake is released. When the handle is raised, the electric motor is disabled and the front wheel is drawn into contact with a braking member. A full set of golf clubs are vertically held in a flat rack forming a part of the cart framework and, after removal of the battery, the cart may be collapsed into a thin flat package, convenient for transporting and storage, without need for removal of the golf clubs.

  • Patent number: 4106583
    Abstract: A power-assisted manually operated golf bag carrying cart is disclosed. The cart features a foldable tricycle support frame having parallel drive wheels, which can be maintained in parallel over a range of adjustment, and independently-powered direct drive d.c. motors coupled to shock isolated wheels. A control scheme is described wherein a hand grip with a mechanically isolated continuously variable throttle provides control signals to a power-control circuit providing independent direct drive to each of the drive wheels. Power supplied by variable pulse width pulse train developing intermittent high peak torque yet low average torque in the normal duty cycle range drives the d.c. motors. The motor drive scheme provides an electrical limited slip differential which permits easy turning without undesirable power dissipation.

  • Patent number: 3989116
    Abstract: A battery-powered cart operatable by a man walking ahead through the medium of a rope attached thereto which is in a forwardly extended state. The rope is connected at the rear end via a sliding member to a spring attached to the cart at a predetermined position in a manner such that the spring urges the rope backwards as it is pulled forwards. The cart incorporates an electric motor, an electromagnetic brake, a battery, and speed-control system electrically connecting with said motor and brake so that the cart moves behind the operator at a speed similar to a man's average walking speed even on a slope, and reduces the speed or comes to a stop as the man slows down or stops because of the slack of the rope.
