ABSTRACT:
A crib having a main frame, a generally horizontal mattress support, and a mattress carried by the support. The mattress and support can be raised and lowered within the main frame by flexible hoist members attached to a winding bar that is rotatably journaled in two housings. Each housing is elongated, extending across one end of the crib, the hoist members being threaded through the housings and attached to the winding bar. At their ends, the hoist members are secured by brackets to a spring frame that forms part of the mattress support. The brackets can be used with spring frames of a variety of constructions. They have an upwardly facing channel that can receive a tubular frame with radius corners and an adjacent slot that can receive a downwardly projecting flange.
