ABSTRACT:
A stretcher includes a patient support portion vertically movably supported on a wheeled base by a lift arrangement. Two pivot members are supported on the support portion for pivotal movement about respective vertical axes, and each support a respective arm for pivotal movement about a respective horizontal axis between a position in which the arms lie in a common horizontal plane and a position in which an outer end of each arm is offset from the plane. The outer end of each arm is movably coupled to a transfer board. A link arrangement effects synchronous movement of the arms about the horizontal axes without movement about the vertical axes and about the vertical axes without movement about the horizontal axes. In a retracted position, the entire transfer mechanism is disposed physically within and has an overall vertical height less than that of the patient support portion.
