1. 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; and
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 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, and
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 rotational lock pivotably coupled to the base member and arranged to abut least a portion of the handle assembly in the locked state to retain the handle extension in the use position.
