Abstract
A combined mobile chair and gurney (10) having an outer base support frame (12) and an inner movable frame (14). Outer support frame (12) has a pair of opposed vertical side frames (16) and a plurality of lower cross members (30) extending between the lower ends of the side frames (16). Inner movable frame (12) has a lower base (84) supported on cross members (30) of the outer frame (12), and a pair of linkages (72, 74) supported on the base (84) connected to three hinged segments (48, 52, 54) which define a rear back support segment (48), an intermediate seat support segment (52), and a front leg support segment (54). The linkages (72, 74) are operatively connected to drive nuts (106, 126) which are mounted on an externally threaded power screw (108) for movement. A patient is supported in a supine position at the uppermost position of the hinged segments (48, 52, 54) shown in FIG. 2 and is supported in a seated position at a lower position of the hinged segments (48, 52, 54) as shown in FIGS. 4 and 5. A modification is shown in FIGS. 10-13 in which manual actuation of the chair and gurney (10A) by a handle (152A) may be provided from either side of the chair and gurney (10A) as may be predetermined.
