Abstract
Abstract An adjustable bed is provided with two frames which rotate about the longitudinal axis of the bed. The rotation is facilitated by a plurality of motors mounted on an undercarriage in which the two frames nest. The motors are controlled by a control unit, which when actuated causes raising or lowering of the nested frames relative to the undercarriage. One or both frames may be raised or lowered at the same time. A limit switch is placed on the frames which prevents the angle formed by the two frames from becoming less than ninety degrees.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
177 words
An adjustable bed having a longitudinal and transverse axis comprising: an undercarriage; two pivot support plates connected to said undercarriage; a first and a second frame nested in said undercarriage; pivot means connecting said first frame to said second frame and further to said support plates; said pivot means defining a longitudinal axis; a plurality of first and second frame support elements connected to said first frame and said second frame, respectively; a first and second frame rotation means located at said transverse axis connected to one of said first frame support elements and one of said second frame support elements, respectively; rotational control means connected to said first and second frame rotation means, respectively; and said rotational control means comprising a limit switch mounted on one of said first and second frames, whereby an angle formed between said first and second frames is constrained to be at least ninety degrees and whereby said first and second frames are rotatable about said bed longitudinal axis relative to each other when said rotational control means is not actuated.
Claim 2
Dependent Claim
177 words
An adjustable bed having a longitudinal and transverse axis comprising: an undercarriage; two pivot support plates connected to said undercarriage; a first and a second frame nested in said undercarriage; pivot means connecting said first frame to said second frame and further to said support plates; said pivot means defining a longitudinal axis; a plurality of first and second frame support elements connected to said first frame and said second frame, respectively; a first and second frame rotation means located at said transverse axis connected to one of said first frame support elements and one of said second frame support elements, respectively; rotational control means connected to said first and second frame rotation means, respectively; and said rotational control means comprising a limit switch mounted on one of said first and second frames, whereby an angle formed between said first and second frames is constrained to be at least ninety degrees and whereby said first and second frames are rotatable about said bed longitudinal axis relative to each other when said rotational control means is not actuated.
Claim 3
Dependent Claim
24 words
An adjustable bed as claimed in claim 1 where said first and second frame each have a top, bottom, inside and outside frame member.
Claim 4
Dependent Claim
26 words
An adjustable bed as claimed in claim 1 where said pivot means comprises a pin whereby said first and second frame are rotatable about said pin.
Claim 5
Dependent Claim
18 words
An adjustable bed as claimed in claim 1 where said frame rotation means includes a plurality of motors.
Claim 6
Dependent Claim
72 words
An adjustable bed as claimed in claim 4 where said frame rotation means further includes a plurality of extensible and retractable screw members respectively attached to said motors and further respectively connected to a plurality of linkages, said linkages are connected to said one of said frame support elements whereby when said motors are actuated, said screw member either extends or retracts, causing said frame member to rotate about said longitudinal axis.
Claim 7
Dependent Claim
37 words
An adjustable bed as claimed in claim 4 including a mesh net connected to said first and second frame respectively, and further connected to said undercarriage whereby said mesh net prevents foreign objects from fouling said motors.
Claim 8
Dependent Claim
47 words
An adjustable bed as claimed in claim 1 including a mattress, said mattress designed to lay atop said first and second frame, said mattress having a longitudinal parabolic cut parallel to said longitudinal axis, whereby said mattress can rotate along with said first or said second frame.
Claim 9
Dependent Claim
29 words
An adjustable bed as claimed in claim 1 whereby said undercarriage has four mounting posts each having a roller, whereby said posts elevate said undercarriage off a supporting surface.
