<p>A portable collapsible crib (120), comprising a rigid frame (123) that is separable at the midpoints (125, 127) of a pair of opposing sides into a first frame half (124) and a second frame half (126), rotatable hinging means (132, 134), coupling said first and second frame halves (124, 126) at said midpoints (125, 127), hingingly operable about first axes for foldably collapsing the first and second frame halves (124, 126) one upon the other at the midpoints (125, 127), and rotatably operable about a pair of second axes that are perpendicular to the first axes for rigidly supporting the first and second frame halves (124, 126) in inflexible planar alignment. Leg means (148, 150, 152, 154) are provided, mounted to and rotatable concurrently with the rotatable hinging means (132, 134), for elevating the frame to a predetermined height when disposed downwardly from the frame, the rotatable hinging means (132, 134) being concurrently rotated into the frame inflexible position, the leg means (148, 150, 152, 154) being further rotatable into parallel planar alignment with the frame (123), with the rotatable hinging means (132, 134) being concurrently rotated into the frame collapsing position. A collapsible crib element (174) is mounted to and supported about the perimeter of the frame (123) and is disposed downwardly therefrom, having rigid floor means (160, 162) removably attached to the leg means (148, 150, 152, 154) at predetermined points below the solid frame (123) when the leg means are rotated and disposed downwardly from the frame and operable to receive the solid frame (123) and the leg means and the collapsible crib structure (174) within the area bounded by the perimeter of the floor means (160, 162) when the leg means (148, 150, 152, 154) are rotated about the frame (123) into the area bounded by the frame, the rotatable hinge means (132, 134) being concurrently rotated into the frame collapsing position. The rigid floor means (160, 162) are further operable to fold about and completely enclose the first and second frame halves (124, 126) when in the frame collapsing position, forming a valise structure thereabout.</p> |
