Claim:
A lift and transfer apparatus for patient, comprising (1) a transferring mechanism including: a support base two support rods pivoted to the support base at rear portions close to rear ends thereof; two front wheels connected to front ends of the support rods; a plurality of rear wheels; and a control member, the control member being pivoted to the support base at a middle portion of an actuating rod thereof; the control member having a pedal rod joined to the actuating rod for changing orientation of the actuating rod with; the control member having two connecting rods; the connecting rods being pivoted to respective ones of the rear ends of the support rods at first ends, and pivoted to respective ones of two ends of the actuating rod at other ends; (2) a lifting mechanism including: a main support post connected to the support base at a lower end; a lifting rod pivoted to an upper end of the main support post for allowing a patient to be hung thereon; and a lifting hydraulic cylinder connected to the lifting rod at an output rod thereof for changing height of the lifting rod with; the support base having a securing portion projecting up therefrom; the securing portion having a locating room defined by front and rear plates, and left and right inverted L shaped plates longer than the front and the rear plates; each inverted L shaped plate having an inverted L shaped guiding slot substantially formed therealong; each inverted L shaped plate having a connecting hole on a lower end; the main support post having an upper, a lower, and an intermediate through holes extending from a left side to a right side of the lower end thereof; the main support post being releasably secured to the securing portion of the support base with a first bolt passing through the lower through hole and the connecting holes of the inverted L shaped plates, and with a second bolt passing through the intermediate through hole and lower ends of the guiding slots; the inverted L shaped guiding slots allowing the main support post to be displaced rewards of the present lift and transfer apparatus until the second bolt, which passes through the intermediate through hole, abuts rear ends of upper portions thereof after the first bolt has been removed, and the second bolt loosened, and after the main support post is pivoted down close to the support rods for folding the present apparatus, thus allowing length of the present apparatus, in folded position, to be reduced.
