ABSTRACT:
A controller for wheeled vehicles includes a mechanism which selectively shifts the vehicle between a mobile and a stable state. The vehicle may be a walker for easing an operator's efforts in walking and includes a selectively actuable stabilizer which fixes the position of the walker or releases it for rolling motion, thus providing a stable state or a mobile state, respectively. An actuator such as a button, pressure sensor, or lever, electrically and/or mechanically actuates a stabilizer brake mechanism to engage or release the brake and thereby allow the walker's mobility to be controlled when the actuator operates the brake to stabilize or to slow the motion of the walker. Preferably, lift applied to the vehicle itself releases the brake and allows mobility. The actuator may control an electrically actuated braking mechanism, in response to a sensor such as a strain gauge that may be adjusted to the needs of the patient; alternatively, lifters may be provided to act in response to the lifting force.
