  • Patent number: 4285079
    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.

  • Patent number: 4139249
    Abstract: A child-proof cabinet latch having a base mounted on an inaccessible inwardly facing surface of a closure panel and a restraining member that is slidable in a guide channel defined by the base. The restraining member is movable between a first position in which an abutment surface is engageable with the cabinet frame to permit only limited opening movement of the panel and a second position in which the abutment surface is not engageable with the frame to permit unlimited opening movement. A spring biases the restraining member toward its first position, the spring force being such that it can be overcome by an adult but not a small child.

  • Patent number: 4048050
    Abstract: A container for medicines and the like that is not readily openable by children, including an enclosure and a cover that is movable both pivotally and longitudinally on the enclosure. A pivot latch will not permit the cover to be pivoted to an open position unless it has first been moved longitudinally, which requires that the sides of the enclosure be pressed inwardly to release a slide latch.
