Abstract
Abstract In abstract a preferred embodiment of this invention is a transfer means for moving incapacitated or partially incapacitated patients or persons from one location to another. A single nurse or orderly can place the patient on the device and move such patient without assistance and without exerting excessive effort and without requiring a great amount of strength. This is accomplished through a counterbalanced arrangement which allows the weight of the patient to be disposed near the center of gravity of the device for easy pivoting and manipulation during the loading, moving and unloading sequence.
