Abstract
An adjustable bed is particularly adapted for the care of morbidly obese patients and comprises a ground engaging frame with a mattress support including a head section, a center section and a foot section which are hingedly interconnected and have power devices which selectively drive lift arms to raise and lower the head and foot sections relative to the center section. To assist entry and exit of a patient onto and off of the bed, a foldable step arrangement is provided which is connected to the foot section and automatically unfolds as the foot section is tilted downward to form a step and folds compactly as the foot section is raised to a horizontal position.

An adjustable bed comprising:
- (a) a ground engaging frame;
- (b) a mattress support including a head section, a center section, and a foot section, each section being pivotally interconnected and having opposite sides;
- (c) said center section being mounted to said frame with said head and foot sections swingably attached to said center section for respective relative raising and lowering;
- and
- (d) a foldable step arrangement mounted to said foot section and having floor supported legs and a patient supportive upper surface;
- said step arrangement including means providing automatic unfolding into a use position as said foot section lowers and providing automatic folding into a nonuse position as said foot section raises.
An adjustable bed for obese patients comprising:
- (a) a heavy duty, ground engaging frame having wheels mounted thereto for movement over a floor surface;
- (b) a central pedestal mounted atop said frame;
- (c) a mattress support including head, center and foot sections having opposite sides and hinges swingably interconnecting said sections;
- (d) said central pedestal supporting said center section a distance above said frame for respective raising and lowering of said head and foot sections relative to said center section;
- (e) panel members of X-ray passive material mounted to said head, center and foot sections and positioned a distance thereabove by spacer members for insertion of X-ray film material;
- (f) expansible spacer members extending between said foot section and the panel member thereabove for elevation of the legs of a patient;
- (g) foot rests slidably mounted to said foot section for adjustment to the length of a patient and having swingably mounted foot plates rotatable over said foot section from the opposite sides of said foot section;
- and
- (h) a foldable step arrangement secured to said foot section for ease of entry and exit by a patient and having upper and lower arms and forward and rearward legs foldably interconnected by hinge means for automatic folding into a nonuse position as said foot section raises and unfolding into a use position as said foot section lowers, said upper and lower arms and forward and rearward legs being arranged in parallelogram relationship;
- (i) said step arrangement including rollers mounting in said hinge means between said lower arm and said rearward leg and floor engaging pads mounted to said lower arm adjacent the juncture thereof with said forward leg for levelly supporting said upper arm.
