Abstract

The invention relates to an adjustable bed having a bottom resting upon a tripartite, hinged frame, and being provided with means for adjusting the bottom from a neutral, horizontal position to an oblique position with the foot end elevated, and to a folded position, wherein the back-supporting part is oblique or vertical, the two other parts forming a reversed V, the adjustment means being designed so as to be operated by a single mechanism maneuvered by the person occupying the bed.

Claims

1. A spaced leg part engaging and supporting means remote from the pivoted end engaged with said leg part and operable on pivoting in one direction to selectively angularly conjointly pivot said back part, said seat part and said leg support part in alignment about said back part fixed pivot support, and in the opposite direction angularly dispose said back part, said seat part and said leg support part with respect to one another.

2. An adjustable bed as claimed in claim 1, said seat part support member being horizontally adjustable for varying angular disposition of the seat part.

3. a leg supporting part;

C. a fixed pivot support for said back part pivotally supporting said back part proximate the end thereof adjacent said seat part;

D. an elongate back part adjustment plate pivotally mounted at an end thereof to said base, and including;

4. An adjustable bed as claimed in claim 1, said adjustment plates being triangular shaped with one side substantially shorter that the other two sides, said plates being pivotally secured to said base at one vertex at the short side, and draw means attached proximate the other vertex of the short side operable for pivoting the plates for adjustment of the bed parts.

5. An adjustable bed as claimed in claim 1, said adjustment plates having arcuate segment shaped means thereon, said draw means passing thereover, and constituting an unwinding curve for said draw means.

6. An adjustable bed as claimed in claim 5, a movable cross bar, a reversibly rotatable spindle and nut assembly for moving said cross bar, said draw means including cables attached to said cross bar and said plates whereby upon movement of said cross bar said plates are rotated for selected movement of said bed parts conjointly.
