Abstract
Abstract A portable crib construction of a type which may be folded to suitcase dimensions in which the end walls of the erected crib are rotated through 270° upon erection to enable the side walls of a base element to serve to elevate the crib bottom from a floor or other horizontal support, thereby eliminating the need for separate retractable legs. The longitudinal side walls of the crib are formed by foldable canvas panels which are separately attached to the base element by resilient fasteners, thereby permitting the erected crib to have a greater length to width ratio than has heretofore been possible in prior art constructions.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
201 words
In a folding crib structure of a type including a hingedly connected base element, a pair of end wall elements, hingedly interconnected to free end edges of said base element, the improvement comprising: said base element including end wall elements and longitudinally extending flanges defining a cavity for the retention of said side wall elements when in folded condition, hinge means interconnecting said end wall elements for rotation through a substantially 270° path of movement, said end walls having laterally extending flanges thereon lying in a plane substantially at right angles relative to the plane of the respective end wall, said laterally extending flanges forming limiting means engaging said base element when said end walls are in fully extended condition, and forming part of a storage enclosure when said structure is in folded condition; a pair of elongated upper rail elements selectively interconnecting said end wall elements when in erected condition, and tensing said end wall elements against said limiting means; and a pair of foldable planar side wall elements of generally rectangular configuration having means along an upper edge thereof selectively engaging said rail elements and at a lower edge thereof selectively engaging a horizontal edge of said base element.

Claim 3
Dependent Claim
48 words
Crib structure in accordance with claim 1, further characterized in said longitudinally extending flanges forming, when said structure is in folded condition, part of a storage enclosure, and when said structure is in erected condition, serving to elevate said base element a substantial distance above a supporting floor.
Claim 4
Dependent Claim
59 words
Crib structure in accordance with claim 1, further characterized in said side wall elements forming a channel along an upper edge thereof into which said rail elements are inserted, said side wall elements including a plurality of resilient fastener elements along a lower edge thereof, selectively engageable with corresponding fastener elements on said lower edge of said base element.
