发明名称 Child safe latch
摘要 A safety latch assembly for securing the door of a cabinet is disclosed. The latch assembly includes a strike plate attached to the cabinet near an access opening, and a resilient striker mounted on the door of the cabinet. The strike plate includes a flat base mounting portion from which an abutment or lip portion projects. The striker includes a flat base mounting portion from which an elongated resilient leaf portion projects. The resilient leaf portion is characterized by a spring constant which permits the leaf, when forced into engagement with the abutment, to deflect and rotate into a latched position thereon in response to a first applied force which is less than a predetermined threshold level, and which permits the leaf to deflect and pass over the abutment in response to an applied force which is equal to or greater than the predetermined threshold level. The position of the striker is adjustable relative to the strike plate to permit the threshold force level to be set to a value sufficiently large to ensure that a child will be physically unable to open the latch, and sufficiently low enough to ensure that an adult can open the latch with relative ease.
