A foldable frame comprises opposing pairs of side and end frame members joined at respective ends to define a generally rectangular and planar frame perimeter. The end members and the side members are generally movable between folded and unfolded positions. The end members are spaced-apart along a longitudinal axis of the frame. The side frame members extend generally parallel to the longitudinal axis to define a frame length. Pivoting connections enable the end members and the side frame members to pivot, each member having a pivot connection at each end thereof. Pivoting of a respective end or side member is permitted when the frame is configured to align the respective end pivots, but is inhibited when the frame is configured to move the respective end pivots out of alignment. The respective pivot axes of the end and side members are generally perpendicular oriented and define a folding and unfolding sequence.

1. A collapsible frame for supporting a child supporting structure above a surface, the frame being moveable between a deployed position for use and a collapsed position for storage, the frame comprising: generally parallel and spaced apart first and second elongate end structures transverse to a longitudinal axis, each end structure having a frame connector disposed at each end; andspaced apart right and left side frame members arranged generally parallel to the longitudinal axis and connected at each end to one of the frame connectors of the first and second end structures, respectively, to define a generally planar rectangular frame perimeter;the frame connectors further comprising first and second end pivoting mechanisms enabling pivoting of the first and second end structures about first and second end pivot axes between an erected position and a folded position, the first and second end pivot axes being transversely aligned to the longitudinal axis; andright and left side wing folding mechanisms enabling pivoting of the right and left side wing structures, each side wing folding mechanism having a first wing pivot disposed at one end of the wing structure and a second wing pivot disposed at an opposite end of the wing structure, the first wing pivot and the second wing pivots each having wing pivot axes that are coaxially aligned when the first and second end structures are in the folded position thereby allowing pivoting of the first and second side wing structures, the first wing pivot and the second wing pivot being non-coaxially aligned when the first and second end structures are not in the folded position thereby preventing pivoting movement of the side wing structures. 2. The collapsible frame of claim 1, wherein the axes of the first wing pivot and the second wing pivot are coaxially aligned on a wing axis parallel to the longitudinal axis when the first and second end structures are in the folded position. 3. The collapsible frame of claim 2, wherein the right and left side wing folding mechanisms enable pivoting movement of the right and left side wing structures between extended and retracted positions when the first and second end structures are in the folded position, the extended position maximizing transverse width between the side rails and the retracted position minimizing transverse width between the side rails. 4. The collapsible frame of claim 3, wherein the first and second end pivoting mechanisms each have a first end pivot and the second end pivot, one end pivot disposed on respective frame connectors at opposing ends of the respective end members, the first and second end pivots having axes coaxially aligned when the right and left side wing structures are in the extended position, the first and second end pivots having axes that are non-coaxially aligned when the right and left side wing structures are in the retracted position. 5. The collapsible frame of claim 4, wherein pivoting movement of the first and second end pivoting mechanisms between the erected and the folded positions ranges from 75 to 105 degrees. 6. The collapsible frame of claim 4, wherein pivoting movement of the right and left side wing folding mechanisms between the first extended and the retracted positions is less than 180 degrees. 7. The collapsible frame of claim 1, further comprising a plurality of support legs, one support leg affixed to each frame connector and extending downwardly from the plane of the frame perimeter. 8. The collapsible frame of claim 7, wherein the plurality of support legs extending downwardly from the plane of the frame perimeter when the first and second end structures are in the erected position and are moved toward alignment with the plane of the frame perimeter when the first and second end structures are in the folded position. 9. A collapsible basinet frame for supporting a child elevated above a surface, the frame comprising: a pair of generally parallel and spaced apart longitudinally oriented side frame members;first and second generally parallel and spaced apart laterally oriented end frame members; anda plurality of frame connectors, each connector moveably attached to an end of one side frame member and an end of one end frame member to form a generally planar frame perimeter, each connector having a support leg affixed thereto and extending away from the plane of the frame perimeter, the plurality of frame connectors further arranged in a first pair having one frame connector disposed at opposing ends of the first frame member and a second pair having one frame connector disposed at opposing ends of the second end frame member, the first and second pairs of frame connectors configured to enable the respective attached support legs to swing about respective first and second end pivot axes toward a folded position in which the support legs are generally parallel to and adjacent to the planar frame perimeter, the frame connectors further configured to enable each side frame member to swing about a respective wing axis that is generally orthogonal to the end pivot axes between generally opposing expanded and collapsed positions, the wing axes of the first and second pairs of frame connectors being aligned only when the support legs are in the folded position. 10. The basinet frame of claim 9, wherein the side frame members are inhibited from movement unless the support legs are in the folded position. 11. The bassinet frame of claim 10, wherein the folding the side frame members about the respective wing axes reduces the width of the bassinet frame by up to one half.
