Invalid bed
First Claim
1. A bed having a head end and a foot end comprising:
- A. a normally horizontal bed frame and a support means beneath the frame, said frame having a central longitudinal centerline of symmetry between two spaced generally parallel longitudinally extending sides,B. an upstanding mattress support structure on the frame, said support structure including;
a) a central portion with a head end zone and a foot end zone,b) a back panel portion extendinq toward the head end from the central portion,c) a distal leg panel with a distal zone having a terminal edge and a proximal leg panel having a distal and a proximal edge and a proximal zone, means pivotally interconnecting said leg panels and said leg panels extending toward the foot end from the central portion, andd) a lift panel at the central portion having a head end and a foot end, said lift panel adapted to swing from a horizontal plane to lift a patient from a supported position to a generally standing attitude,C. said mattress support structure including pivot means interconnecting thea) foot end zone of the central portion to the proximal zone of the leg panels,b) the head end zone of the central panel to the back panel, andc) the central portion to the lift panel,d) said panels being normally in a co-planar generally horizontal relation to one another to support a mattress,e) each panel having a centerline normally aligned in co-planar relationship with the centerline of the mattress frame,f) means on the mattress support structure to support the panels,D. means journaling the mattress support structure on the frame for rotating the mattress support structure through an angle of about 90°
so that the centerlines of the panels are in a common vertical plane generally perpendicular to the frame centerline, andE. drive means to pivotally and selectively lift the panels from the normal co-planar relationship and to rotate the mattress support structure.

Abstract
A conventional adjustable hospital bed of the type on which a person can selectively change his position by pivotally raising a back panel and/or raising pivotally interconnected leg panels. Additionally, the bed includes a rotatable carriage beneath the mattress to rotate the mattress, out of parallel coalignment with the bed, while the person is supported on the mattress, to a position at about 90° thereto, the occupant can then be lifted to a standing position with the aid of a tiltable panel to, in effect, provide assistance in getting out of the bed. The mattress is supported on a rotatable carriage assembly at one end of which is the back support panel and at the other end of which are the leg support panels with the ejector panel being centrally located between the back and leg panels. The panels are moved by energizing motors, selectively by the patient.
