Abstract A folding bed having a rectangular frame divided longitudinally into four equal sections and foldable to have each section lie flat against the next adjacent section. The two central sections are pivotable about a non-foldable leg and are foldable to lie against such leg. The two outer sections are supported in use by foldable legs while one of the outer sections is inclined to the plane of the frame when in its open position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
184 words
A folding bed, comprising a substantially rectangular frame adapted to carry body supporting means in the plane thereof and articulated longitudinally into two central sections and two end sections; a central U-shaped leg having the upper free ends thereof secured to the vertical stems of a pair of T-shaped brackets, the two central sections of the frame being pivotally attached to the lateral arms of said T-shaped bracket so as to be foldable downwardly to lie against said central leg; the two end sections of the frame being pivotally attached to their adjacent central sections and foldable upwardly to lie against said central sections; longitudinally spaced legs pivotally attached to each central section remote from and on the opposed longitudinal sides of said central leg and foldable upwardly to lie against said central sections; a further leg pivotally attached to one of the end sections remote from the leg of the adjacent central section and foldable upwardly to lie against said end section; and means for releasingly securing the other of the end sections in a plane inclined to the plane of the frame.
Claim 2
Dependent Claim
184 words
A folding bed, comprising a substantially rectangular frame adapted to carry body supporting means in the plane thereof and articulated longitudinally into two central sections and two end sections; a central U-shaped leg having the upper free ends thereof secured to the vertical stems of a pair of T-shaped brackets, the two central sections of the frame being pivotally attached to the lateral arms of said T-shaped bracket so as to be foldable downwardly to lie against said central leg; the two end sections of the frame being pivotally attached to their adjacent central sections and foldable upwardly to lie against said central sections; longitudinally spaced legs pivotally attached to each central section remote from and on the opposed longitudinal sides of said central leg and foldable upwardly to lie against said central sections; a further leg pivotally attached to one of the end sections remote from the leg of the adjacent central section and foldable upwardly to lie against said end section; and means for releasingly securing the other of the end sections in a plane inclined to the plane of the frame.
Claim 3
Dependent Claim
23 words
A folding bed according to claim 1, including gripping means fixed to at least one end of the frame for carrying the bed.
Claim 4
Dependent Claim
24 words
A folding bed according to claim 1, wherein said releasable securing means is adapted to releasably lock the bed in its fully folded position.
Claim 5
Dependent Claim
36 words
A folding bed according to claim 3, wherein the releasable securing means comprises a latch pivotally mounted at one end on said other end section and engagable with a pin projecting from the opposed end section.
Claim 6
Dependent Claim
37 words
A folding bed according to claim 1, wherein the end sections of the frame are connected to the adjacent central sections by U-shaped springs to accommodate a mattress where the bed is in its fully folded position.
Claim 7
