Abstract
Abstract A folding bed including a main frame and an inner bed spring frame pivotally connected to the main frame at generally the longitudinal midpoint of said bed spring frame. The latter can be inclined relative to the main frame and locked in the desired position of adjustment. To store the bed, the inner bed spring frame can be disposed parallel to and within the main frame and the legs of the bed folded to provide a compact assembly. Inflatable pillows and mattress are stored in a deflated condition.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
A folding bed comprising a. a main bed frame, b. a pair of legs at each end of said main frame and hinged thereto, said legs folding from a supporting position to a folded position generally within the plane of said main bed frame, c. a bed spring frame disposed within said main bed frame, said bed spring frame and said main frame being of generally the same depth whereby when said legs are folded within the plane of said main frame, a compact, relatively flat bed assembly is provided, d. pivot means for pivotally mounting said bed spring frame on a single axis generally intermediate the length of said bed spring frame thereby to permit said bed spring frame to be inclined relative to said main frame to the desired patient position, and e. locking means associated with said pivot means to maintain said bed frame either in a position generally parallel to said main bed frame or at an angle inclined thereto.
Claim 2
Dependent Claim
164 words
A folding bed comprising a. a main bed frame, b. a pair of legs at each end of said main frame and hinged thereto, said legs folding from a supporting position to a folded position generally within the plane of said main bed frame, c. a bed spring frame disposed within said main bed frame, said bed spring frame and said main frame being of generally the same depth whereby when said legs are folded within the plane of said main frame, a compact, relatively flat bed assembly is provided, d. pivot means for pivotally mounting said bed spring frame on a single axis generally intermediate the length of said bed spring frame thereby to permit said bed spring frame to be inclined relative to said main frame to the desired patient position, and e. locking means associated with said pivot means to maintain said bed frame either in a position generally parallel to said main bed frame or at an angle inclined thereto.
Claim 3
Dependent Claim
72 words
The folding bed of claim 1 further including supplemental means to maintain said bed frame in a position generally parallel to said main bed frame, comprising a pair of locking pins carried by said bed spring frame, means for biasing said pins into slots provided therefor in said main frame, and means for retracting said pins from said slots to permit movement of said bed spring frame relative to said main frame.
Claim 4
Dependent Claim
108 words
The folding bed of claim 1 wherein said pivot means for pivotally mounting said bed spring frame on said main bed frame comprises a mounting bolt extending through aligned openings provided therefor in the adjacently disposed portions of said main frame and said bed spring frame, said locking means to maintain said bed frame either parallel or inclined to said main frame comprising locking members carried by the respective frames in the area of their pivotal connection, and means to move said locking members toward each other in locking arrangement or away from each other to permit movement of said bed spring frame relative to said main frame.
Claim 5
Dependent Claim
40 words
The folding bed of claim 3 further including a threaded sleeve carried by said mounting bolt, and handle means exposed at the exterior of said bed for rotating said sleeve for positioning said locking members in locked and unlocked positions.
Claim 6
Dependent Claim
63 words
The folding bed of claim 1 further including supporting brace members pivotally carried by said main frame and provided with generaLly oblong shaped openings with entrance slots to receive pins disposed at either side of said bed spring frame, with engagement of said pins in selected openings in said braces serving to maintain said bed spring frame in the desired angle of inclination.
Claim 7
Dependent Claim
47 words
The folding bed of claim 1 further including an inflatable mattress and inflatable bags or pillows for supporting said mattress when inflated in the desired patient position, the inflation of said mattress and pillows permitting storage of the same on said bed spring frame for convenient storage.
