<p>A braking system (30) for a hospital bed (20) having a base frame (28) includes a plurality of caster devices (44) rotatably coupled to the base frame (28). Each caster device (44) has a caster frame, a wheel (55) rotatably attached to the caster frame, a brake (48) attached for movement with respect to the caster frame between a first position in which the brake (48) inhibits rotation of the wheel (55) and a second position in which the brake (48) permits the wheel (55) to rotate freely. The caster device (44) also includes an actuator (128), a plurality of pedals (56) each adjacent to a different one of the plurality of caster devices (44) and coupled to the actuator (128) for movement of the brake (48) between the first position and second position in response to movement of the pedal (56), and a linkage coupled to all of the actuators (128) of the plurality of caster devices (44) so that movement of any one of the plurality of pedals (56) causes movement of all of the actuators (128).</p> |
