Abstract

A bed resting on a floor includes a base frame, a plurality of casters coupled to the base frame and configured to engage the floor, a first brake coupled to the base frame, a foot pedal actuator movable between a first position and a second position, and a second brake coupled to the base frame. A linkage is configured to couple the second brake to the first brake so that when the foot pedal actuator is moved to the second position, the first and second brakes both move to a braking position and when the foot pedal actuator is moved to the first position the first and second brakes both move to a releasing position.
