First Claim
1. A method of actuating a brake on a caster wheel of a patient support apparatus to stop motion of the apparatus, the patient support apparatus including a support frame and a plurality of caster wheels supporting the frame, a patient support surface supported by the support frame, and at least one manually operable brake for manually braking the caster wheels, the patient support apparatus further including an actuator for selectively outputting a driving force and a control system, said method comprising:
- electrically coupling the control system to the actuator;
generating actuating signals with said control system based on input at the patient support apparatus;
transmitting the actuating signals to the actuator to thereby actuate the actuator to output a driving force; and
mechanically coupling the driving force of the actuator with the manually operable brake to thereby actuate the manually operable brake and thereby brake the caster wheels.

Abstract
A method of actuating a manually operable brake on a caster wheel of a patient support apparatus to stop motion of the apparatus includes electrically coupling the control system of the patient support to an actuator at the patient support, generating actuating signals with the control system based on input at the patient support apparatus, transmitting the actuating signals to the actuator to thereby actuate the actuator to output a driving force, and mechanically coupling the driving force of the actuator with the manually operable brake to thereby actuate the manually operable brake and thereby brake the caster wheels.
