A system for attachment to a child's crib combining a side rail and a ramp structure that serve to prevent the child from rolling out during sleep, and at the same time provide a means for the child to climb or crawl into or out from the crib. Components include a side rail fixed to the crib at each end by removable straps or the like, and rigidly connected to a pair of legs that slide between the mattress and box spring of the crib. A generally larger ramp component extends pivotally outward and downward from the side rail component to a point in contact with the floor. Embodiments include multiple hinged components within the ramp system to allow alternate positioning of the ramp (in whole or in parts) in an extended or a collapsed configuration.

I claim: 1. A system for allowing access to, and egress from, a child's crib by the child using said crib, said crib positioned on a support surface and having an elevated sleeping surface enclosed on three of four sides, said child being too small to easily access the height of said sleeping surface on said crib but agile enough to climb an inclined surface to such a height, the system comprising: a ramp frame positioned proximate to said crib, said frame defining an inclined plane extending continuously from a location adjacent said elevated sleeping surface of said crib along an unenclosed one of said four sides of said elevated sleeping surface, to a location on said support surface apart from said crib, said ramp frame having a width approximately equal to a width of said unenclosed one of said four sides of said elevated sleeping surface; and a ramp surface positioned on and attached to said ramp frame, said ramp surface further defining said inclined plane and providing the surface to said inclined plane extending continuously from said elevated sleeping surface to said support surface, said ramp surface capable of supporting the weight of said child ascending or descending between said elevated sleeping surface and said support surface. 2. The system of claim 1 wherein said ramp frame is pivotally attached to said crib at at least one point along said width of said unenclosed one of said four sides of said elevated sleeping surface. 3. The system of claim 2 wherein said ramp frame further comprises a plurality of hinge joints, said hinge joints allowing said frame to be folded so as to collapse against the side of said crib in a manner that allows direct access to the side of said crib. 4. The system of claim 3 wherein said ramp frame comprises first and second ramp elements and said ramp surface comprises first and second surface elements, each of said ramp elements defining a divided portion of said inclined plane, each of said ramp elements independently foldable against the side of said crib and independently extendable to said support surface. 5. The system of claim 2 wherein said ramp fame is removably attachable to said crib and further comprises a plurality of pivoting, releasable connectors. 6. The system of claim 5 wherein said plurality of pivoting, releasable connectors each comprise a spring-loaded/closing, hand-operable/opening, engagement hook capable of being hooked onto said crib and holding said ramp frame captive on said crib when released. 7. The system of claim 1 further comprising a railing positioned on and attached to said crib so as to provide low level closure of said unenclosed side of said sleeping surface, said low level closure extending fully across said open side of said sleeping surface and above said sleeping surface but below a level of enclosure on the remaining three sides, said railing comprising and providing a point of attachment between said ramp frame and said crib. 8. The system of claim 7 wherein said ramp frame is pivotally attached to said railing. 9. The system of claim 8, wherein said ramp frame is removably attachable to said railing and further comprises a plurality of pivoting, releasable connectors. 10. The system of claim 9 wherein said plurality of pivoting, releasable connectors each comprise a spring-loaded/closing, hand-operable/opening, engagement hook capable of being hooked onto said railing and holding said railing captive when released. 11. The system of claim 7 wherein said crib comprises corner posts and said system further comprises attachment straps for securing said railing to said crib at least one of said corner posts. 12. The system or claim 7 wherein said railing further comprises at least one under mattress leg, said at least one leg providing a rigid support to help maintain said railing in an upright position adjacent said sleeping surface. 13. The system of claim 7 wherein said railing comprises a horizontal top bar and a horizontal bottom bar and a plurality of vertical rungs extending between said top bar and said bottom bar. 14. The system of claim 13 wherein said horizontal bottom bar comprises upper and lower parallel bottom bar elements, said plurality of vertical rungs extending from said upper bottom bar element and said ramp frame is attached to said upper bottom bar element. 15. The system of claim 7 wherein said ramp frame further comprises a plurality of hinge joints, said hinge joints allowing said frame to be folded so as to collapse against the side of said railing and said crib in a manner that allows direct access to the side of said crib. 16. The system of claim 15 wherein said ramp frame comprises first and second ramp elements and said ramp surface comprises first and second surface elements, each of said ramp elements defining a divided portion of said inclined plane, each of said ramp elements independently foldable against the side of said railing and said crib and independently extendable to said support surface. 17. The system of claim 1 wherein said ramp frame comprises a plurality of tubular components connected together by a plurality of joint components. 18. The system of claim 1 wherein said ramp surface comprises a fabric material stretched across and secured to said ramp frame. 19. The system of claim 18 wherein said fabric material comprises an open mesh fabric constructed of soft polyester fibers.
