Abstract

Abstract A foldable bed is formed from a pair of substantially U-shaped end members joined together by a pair of connecting links. A flexible sheeting is secured to the frame formed by the U-shaped 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, each leg being connected to one of the U-shaped members. The connecting links are characterized by a pair of cutouts forming end tabs for connection to the U-shaped members. One of the cut-outs is of lesser extent that the other whereby end portions of the U-shaped 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: 5
Claim 1
Independent Claim 194 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, and b. a pair of links pivotally connecting said end 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 of the end members and adapted to cooperate with the car seat to support the frame and flexible covering; said connecting links having a pair of tab members at each at each end thereof pivotally connected to end portions of the Ushaped 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 U-shaped 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 U-shaped 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 raised seat.
Claim 2
Dependent Claim 194 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, and b. a pair of links pivotally connecting said end 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 of the end members and adapted to cooperate with the car seat to support the frame and flexible covering; said connecting links having a pair of tab members at each at each end thereof pivotally connected to end portions of the Ushaped 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 U-shaped 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 U-shaped 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 raised seat.
Claim 3
Dependent Claim 22 words
A foldable bed as defined in claim 1 wherein the U-shaped members and the connecting links are formed from tubular metal material.
Claim 4
Dependent Claim 44 words
A foldable bed as defined in claim 2 wherein the connecting links are also formed from tubular metal material and the end portions of the U-shaped members are of a lesser cross-sectional extent than the distance between adjacent tab members and moveable in between.
Claim 5
Dependent Claim 53 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 U-shaped 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.
