ABSTRACT:
A lift and transfer device includes a wheeled chassis provided with an upright frame which at a lower end thereof connects to a pair of sidewardly spaced and rearwardly cantilevered support legs provided with floor-engaging drive rollers adjacent the rear free ends thereof. A lifting arm arrangement is pivotally supported on the frame adjacent an upper end thereof and is connected to an actuating device to control vertical swinging of the arm arrangement. The arm arrangement is preferably defined by a four-bar linkage which, at its outer free end, mounts a patient carrier. The latter is vertically moved by the lift arm arrangement in a controlled and stable manner so that its position is stably defined, and the patient carrier permits removable attachment thereto of a patient-engaging sling arrangement to provide stable support of the patient during use of the device for moving or transferring the patient. The support legs are swingable between inner and outer positions whereby the inner position of the legs provides a narrower and more compact arrangement to enable the lift to pass through standard doorways, whereas the outer position provides a flared enlarged opened space to facilitate positioning of a wheelchair or other object between the legs when transfer of a patient is desired.
