A substantially planar support structure 30 is formed between first connector assemblies 16 and second connector assemblies 18 and between first connector assemblies 16 and third connector assemblies 20. Substantially planar support structure 30 is configured to support mattress 12. More specifically, substantially planar support structure 30 includes at least one foldable cross-support unit 32. In one embodiment, a plurality of cross-support units 32 are movable between an extended configuration, as shown in
Cross-support unit 32 includes a first member 34 and a second member 36 coupled together. Each first member 34 and second member 36 has a first end 37, a second end 38 and an intermediate point 40 therebetween. First member 34 is pivotally coupled to second member 36 at a respective intermediate point 40. First member 34 is coupled to a corresponding first connector assembly 16 at first end 37 and to a corresponding second connector assembly 18 at second end 38. Similarly, second member 36 is coupled to a corresponding first connector assembly 16 at first end 37 and to a corresponding second connector assembly 18 at second end 38. Each first member 34 and each second member 36 are coupled to first portion 24 of a corresponding first connector assembly 16 such that cross-support unit 32 is pivotally movable with respect to first upright members 17 about longitudinal axis 22. More specifically, with cross-support unit 32 in the folded configuration, each first member 34 and each second member 36 is pivotally movable with respect to a corresponding first upright member 17 about longitudinal axis 22 to move frame 10 towards the collapsed configuration.
Similarly, the second cross-support unit 32 includes first member 34 and second member 36 coupled together at intermediate point 40. First member 34 is coupled to a corresponding first connector assembly 16 at first end 37 and to a corresponding third connector assembly 20 at second end 38. Similarly, second member 36 is coupled to a corresponding first connector assembly 16 at first end 37 and to a corresponding third connector assembly 20 at second end 38. Each first member 34 and each second member 36 are coupled to second portion 26 of a corresponding first connector assembly 16 such that cross-support unit 32 is pivotally movable with respect to first upright members 17 about longitudinal axis 22. More specifically, with cross-support unit 32 in the folded configuration, each first member 34 and each second member 36 is pivotally movable with respect to a corresponding first upright member 17.

As shown in
In a further embodiment, frame 10 includes additional support members, such as a first frame member 90 and/or a second frame member 92. As shown in
More specifically, as cross-support unit 32 is moved from the folded configuration to the expanded configuration, extendible support member 41 coupled between first portion 24 of first connector assembly 16 and a corresponding second connector assembly 18 moves from the extended configuration to the retracted configuration and second upright members 19, coupled via first frame member 90 to first portion 24, pivot outwardly with respect to cross-support unit 32. With cross-support unit 32 in the expanded configuration, second upright members 19 are substantially perpendicular to cross-support unit 32. As cross-support unit 32 is moved from the expanded configuration to the folded configuration, extendible support member 41 moves from the retracted configuration to the extended configuration and second upright members 19 pivot inwardly towards cross-support unit 32. In one embodiment, movement of extendible support member 41 facilitates urging second upright members 19 to pivot. With cross-support unit 32 in the folded configuration, second upright members 19 are substantially parallel to cross-support unit 32. Further, with cross-support unit 32 in the folded configuration, cross-support unit 32 is pivotally movable with respect to first upright members 17 to facilitate moving frame 10 towards the collapsed configuration. More specifically, cross-support unit 32 pivots with respect to first upright member 17 through first portion 24 of first connector assembly 16 pivotally coupled to first upright member 17.
Similarly, as a laterally opposing second cross-support unit 32 is moved from the folded configuration to the expanded configuration, a second extendible support member 41 coupled between second portion 26 of first connector assembly 16 and a corresponding third connector assembly 20 moves from the extended configuration to the retracted configuration and third upright members 21, coupled via second frame member 92 to second portion 26, pivot outwardly with respect to second cross-support unit 32. In one embodiment, movement of extendible support member 41 facilitates urging third upright members 21 to pivot. With second cross-support unit 32 in the expanded configuration, third upright members 21 are substantially perpendicular to second cross-support unit 32. As second cross-support unit 32 is moved from the expanded configuration to the folded configuration, second extendible support member 41 moves from the retracted configuration to the extended configuration and third upright members 21 pivot inwardly towards second cross-support unit 32. With second cross-support unit 32 in the folded configuration, third upright members 21 are substantially parallel to second cross-support unit 32. Further, with second cross-support unit 32 in the folded configuration, second cross-support unit 32 is pivotally movable with respect to first upright members 17 to facilitate moving frame 10 towards the collapsed configuration. More specifically, second cross-support unit 32 pivots with respect to first upright member 17 through second portion 26 of first connector assembly 16 pivotally coupled to first upright member 17.

In one embodiment, the frame includes a plurality of first connector assemblies, a plurality of second connector assemblies, and a cross-support unit coupled between the plurality of first connector assemblies and the plurality of second connector assemblies such that the plurality of first connector assemblies move along a longitudinal axis of the frame as the frame moves from a folded configuration to an expanded configuration. The cross-support unit is moved between the folded configuration and the expanded configuration to define the substantially planar support structure in the expanded configuration. As the cross-support unit is moved from the folded configuration to the expanded configuration, a distance between adjacent first connector assemblies is increased. In a particular embodiment, each first connector assembly includes a first portion and a cooperating second portion. As the cross-support unit is moved, the first portion is coupled to the second portion to facilitate retaining the collapsible frame in the expanded configuration. In a further embodiment, a projection formed on or coupled to the first portion is positioned within a slot defined within the second portion. With the frame in the expanded configuration, a mattress is positioned on the substantially planar support structure.
In a particular embodiment, an extendible support member is coupled between one first connector assembly and a corresponding laterally aligned second connector assembly or laterally aligned third connector assembly. As the cross-support unit is moved, the extendible support member also moves from an extended configuration and a retracted configuration. The extendible support member can be locked in the desired configuration.
Further, the cross-support unit is pivotally movable with respect to a plurality of first upright members each coupled to a corresponding first connector assembly to facilitate moving the frame between the folded configuration and a collapsed configuration for storing and/or transporting the frame. A plurality of second upright members are pivotally coupled to a corresponding first member or corresponding second member of the cross-support unit. Each second upright member is pivotally moved with respect to the corresponding first member or second member to facilitate moving the frame to the collapsed configuration.
