Claim 9:
10. A patient transport apparatus for transporting a patient, the patient transport apparatus comprising:
a support structure comprising a base, a frame, and a patient support surface to support the patient;
wheels coupled to the base to facilitate movement of the support structure;
a handle assembly including:
a base member operatively attached to the frame,
a handle to be manipulated by a user to manually move the support structure, and
a handle extension supporting the handle and being movably coupled to the base member adjacent to a distal end portion for articulation relative to the frame between a stowed position and a use position such that the handle is adjacent to the frame in the stowed position and the handle is extended from the frame by the handle extension in the use position;

a locking device operable between a locked state and an unlocked state to discretely lock and unlock the handle assembly relative to the frame, the locking device including:
a cot pin operatively attached to the base member of the handle assembly, and
a wedge pin arranged to contact the cot pin in the locked state; and

a manual release actuator coupled to the handle extension adjacent to the distal end portion for concurrent movement with the handle extension between the stowed position and the use position, the manual release actuator being operatively attached to the wedge pin and arranged for engagement by the user to place the locking device in the unlocked state while the user grasps the handle extension to bring the wedge pin out of contact with the cot pin and allow the user to articulate the handle extension between the use position and the stowed position.
