Abstract: A child-proof drawer lock assembly for drawers fitted with or without drawer slide rollers. The lock assembly is movably mounted on the external drawer side of the drawer. A restraining member is mounted to a lever that is accessible when the drawer is partially opened. The restraining member alternatively engages a cabinet-mounted drawer slide roller through a slot in the drawer-mounted drawer slide or engages the interior of the cabinet face. The drawer is unlatched by lifting the pivotally mounted lever a sufficient distance so that the restraining member clears the roller, or the cabinet face, while the drawer is conventionally opened. The assembly can also be disengaged to allow for conventional operation of the drawer.
