ABSTRACT:
A castor control mechanism for a hospital bed having a plunger type neutral/brake/steer castor comprises a linkage including a rocker arm pivotally mounted to the base of the bed, a link connected on one end to the rocker arm and being connected on its other end through a cam and follower mechanism to a shaft rotatably mounted to the base and rotatable by a foot pedal. Operation of the foot pedal moves the plunger of the castor via the rocker arm to place the castor in its steer, neutral and brake positions.
