  • Publication number: 20120137817
    Abstract: A power control member for manned vehicles is revealed. The power control member includes a handle, a stem support and a power controller. The handle is sleeved and assembled with the stem support of a manned vehicle, and the power controller is arranged between the handle and the stem support. A power control shaft of the power controller shares the same axis with the handle and connects to the handle. Thereby rotation of the handle drives the power controller to control the direction and speed of the manned vehicle.

  • Patent number: 8038165
    Abstract: A foldable wheeled vehicle for individuals includes a main body, front and rear wheels joined on the body, and an anti-tip wheel joined on a rear end of the main vehicle body; the rear wheels will be in an immobilized state when the vehicle isn't in-use; the anti-tilting wheel will move to be below the rear wheels automatically when the vehicle is folded; thus, the vehicle in the folded position can be dragged with the front wheels and the anti-tip wheel contacting the ground; secondly, the anti-tip wheel will be in a higher position than the rear wheels when the vehicle is in an expanded in-use position; thus, when the vehicle is moving along a slope and tilting rearwards, the anti-tip wheel will contact the ground to prevent the vehicle from tilting rearwards excessively to overturn.

  • Patent number: 7954577
    Abstract: An electric wheelchair is disclosed. The electric wheelchair includes a main frame correspondingly pivoted with a foldable chair while the folding of the chair connects with an accessory tip wheel. Moreover, the main frame is disposed with main wheels and a front wheel set arranged on front of the main wheel correspondingly on each of two sides thereof. A footrest that is pulled out or stored in the main frame is arranged between the two front wheel sets. In use, the footrest is pulled out of the main frame and the chair is moved and unfolded. At the same time, the accessory tip wheel tilted a little angle is extended out of the main frame by a connecting member. Thereby the problem caused by movement of the center of gravity of the wheelchair while moving can be solved and the safety of users is ensured.
