Abstract
A wheeled walker includes a walker frame with user supports and a plurality of downwardly extending legs with wheel assemblies attached to a plurality of the walker legs. Each wheel assembly includes a base member with a wheel rotatably supported on the base member and a wheel alignment mechanism for moving the base member and the wheel. The wheel alignment mechanism will move the base member and the wheel between at least a first position in which the wheel is angled with respect to the direction of travel of the walker and a second position in which the wheel is aligned with the direction of travel of the walker. The wheel mechanism moves the base member and the wheel in response to the vertical force exerted on the base and the wheel. The walker including the wheel assembly having the wheel alignment mechanism provides a method for braking a wheel walker which brakes the walker by moving the associated wheel to a position at angle with respect to the direction of travel of the walker in response to appropriate vertical forces on the walker.
