Abstract
Abstract A bed comprises a main portion and two extension portions, one at each end of the main portion and pivotable to positions underlying the main portion, when not required for use. A cage is provided, which in the folded position of the bed can be attached to it to form a cot, and which on its own can form a playpen. When the bed is in the extended position, panels of the cage can be attached to it to form safety panels.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
186 words
A bed of adjustable length providing in a shorter length a cot and in a longer length a bed comprising: a main structure which has a substantially flat upper surface that defines the bed surface and legs towards the opposite ends thereof that support the main structure; a pair of additional foldable structures each one of which is pivotally connected to respective ones of the opposite ends of the main structure and movable between an extended position, wherein the main structure is lengthened, and a collapsed position, wherein during movement to said collapsed position each foldable structure folds so as to be parallel but beneath the opposite ends of the main structure, each of said foldable structures being comprised of a pair of arms pivotally connected to the main structure and support means pivotally connected to each of the arms for supporting the latter parallel to the main structure when in the extended position, the relative lengths of the arms and the support means being such as to provide additional support for bed material at the opposite ends of the main structure in said collapsed position.
Claim 2
Dependent Claim
186 words
A bed of adjustable length providing in a shorter length a cot and in a longer length a bed comprising: a main structure which has a substantially flat upper surface that defines the bed surface and legs towards the opposite ends thereof that support the main structure; a pair of additional foldable structures each one of which is pivotally connected to respective ones of the opposite ends of the main structure and movable between an extended position, wherein the main structure is lengthened, and a collapsed position, wherein during movement to said collapsed position each foldable structure folds so as to be parallel but beneath the opposite ends of the main structure, each of said foldable structures being comprised of a pair of arms pivotally connected to the main structure and support means pivotally connected to each of the arms for supporting the latter parallel to the main structure when in the extended position, the relative lengths of the arms and the support means being such as to provide additional support for bed material at the opposite ends of the main structure in said collapsed position.
Claim 3
Dependent Claim
16 words
The bed as defined in claim 1, wherein said support means is a generally U-shaped member.
Claim 4
Dependent Claim
141 words
A bed as claimed in claim 1 wherein there are provided a pair of resilient mattresses of similar breadth, one being half the thickness of the other, the two mattresses being so dimensioned as, in the collapsed position of the additional structures, to lie on top of one another to cover the upper surface of the main structure and in the extended position to lie in end-to-end abutting relationship with the thinner mattress folded in half across its length, to form together a substantially continuous mattress covering the surfaces of the main structure and the additional structures; and the additional structures are together one half the length of the main structure and the resilient mattresses are of the same length so that in the collapsed position of the bed the two mattresses are substantially coextensive when covering the flat upper surface.
Claim 5
Dependent Claim
64 words
A bed as claimed in claim 1 wherein a cage is provided around the surface of the main structure in said collapsed position, the cage of the additional structures comprising a plurality of connected frames detachably connected to the main structure to form a vertical wall around its upper surface; and the cage is detachably secured to the main structure by means of clips.
Claim 6
Dependent Claim
125 words
A bed as claimed in claim 1 wherein a cage is provided around the surface of the main structure in said collapsed position, the cage of the additional structures comprising a plurality of connected frames detachably connected to the main structure to form a vertical wall around its upper one of said frames which frame is movable relative to the others in a vertical plane between a raised position in which said one frame is in vertical alignment with the other frames and a dropped position below the vertical level of the other frames; and releasable detent means are provided on said one frame whereby said one frame may be held in a number of intermediate positions between the raised position and the dropped position.
