Abstract
Abstract A foldable bed is formed from a pair of substantially U-shaped end members joined together by intermediate members and connecting links. A flexible sheeting is secured to the frame formed by the U-shaped members, the intermediate members and the connecting links and provides a support platform for the bed. A pair of swingable legs are provided on one side of the frame. The connecting links are characterized by a pair of cut-outs forming end tabs for connection to the intermediate members and the Ushaped members. One of the cut-outs is of lesser extent than the other whereby end portions of the U-shaped members and the intermediate members may be pivoted about the tabs for folding the bed into a compact condition and, also, for supporting the members when the bed is extended to an open position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
208 words
A foldable bed having a support platform area and adapted to be used with a raised seat, said bed comprising: a substantially rectangular shaped frame including a. a pair of substantially U-shaped end members, b. a pair of intermediate members, and c. two pairs of links pivotally connecting said end members and intermediate members together; a flexible sheeting securely attached to said frame and forming the support platform; a pair of swingable leg supports each connected to one side of the frame and adapted to cooperate with the raised seat to support the frame and flexible covering; said connecting links having a pair of tab members at each end thereof pivotally connected to end portions of the end members and the intermediate members; said tab members being formed by cut-out portions on opposite sides of said links, one cut-out being of lesser extent than the other whereby the end portions of the end members may be pivoted about the tabs and through the greater cut-outs for folding the bed into a compact condition and also for supporting the end members and the intermediate members by the portions of the links adjacent the lesser cut-outs when the bed is extended into an open position for engagement with the seat.

A foldable bed having a support platform area and adapted to be used with a raised seat, said bed comprising: a substantially rectangular shaped frame including a. a pair of substantially U-shaped end members, b. a pair of intermediate members, and c. two pairs of links pivotally connecting said end members and intermediate members together; a flexible sheeting securely attached to said frame and forming the support platform; a pair of swingable leg supports each connected to one side of the frame and adapted to cooperate with the raised seat to support the frame and flexible covering; said connecting links having a pair of tab members at each end thereof pivotally connected to end portions of the end members and the intermediate members; said tab members being formed by cut-out portions on opposite sides of said links, one cut-out being of lesser extent than the other whereby the end portions of the end members may be pivoted about the tabs and through the greater cut-outs for folding the bed into a compact condition and also for supporting the end members and the intermediate members by the portions of the links adjacent the lesser cut-outs when the bed is extended into an open position for engagement with the seat.
Claim 3
Dependent Claim
24 words
A foldable bed as defined in claim 1 wherein the end members, intermediate members and the connecting links are formed from tubular metal material.
Claim 4
Dependent Claim
37 words
A foldable bed as defined in claim 2 wherein the end portions of the end members and the intermediate members are of a lesser cross-sectional extent than the distance between adjacent tab members and moveable in between.
Claim 5
Dependent Claim
56 words
A foldable bed as defined in claim 1 wherein the flexible sheeting is tautly attached to the support platform by means of securing means about the end members, the intermediate members and adjacent to the links whereby the portion of the sheeting between said links remains taut under a load or when the bed is folded.
Claim 6
Dependent Claim
84 words
A foldable bed as defined in claim 1, wherein the swingable leg supports are connected to the frame by means of a connector and a spring loaded retention mechanism, said cOnnector including a strap portion wrapped about the frame and connected to the leg support, the spring loaded retention mechanism including a stub portion adapted to be spring forced into holding engagement with an opening in the connector and an opening in the frame, whereby the leg supports are held in an in-use position.
