Abstract: Drop side of a child-proof crib has a top portion which can be lowered with respect to its bottom portion. Its top railing is rendered vertically translatable by employing telescoping stiles between it and the bottom railing. Double-action latch mechanisms in the upper railing hold the drop-side upper portion up. The drop-side upper railing has an upper bar fixedly secured upon a lower bar: the lower surface of the upper bar opens to a longitudinally-extending groove slidably receiving rods of the two latches that are biased outwardly from central triggers to beyond the outer ends of the railing to where they each engage on their free ends a shoulder-bearing latch bracket mounted on the opposing face of the associated corner post. Crib mattress platform is adjustable vertically using plunger latch mechanisms whose plungers are withdrawable only by inserting a tool through a narrow slot in the platform.
