摘要：A latching assembly that requires three distinct operations must be performedwith two hands to allow the handle of the latch assembly to be rotated to unlock acabinet door or the like. The assembly provides substantial flexibilities in installation. Abase portion is secured to a door and receives a handle portion with a shaft attached, the

shaft extending through the sleeve. Cooperative rotation restriction portions on thehandle and on the base portion restrict the motion of the handle to a limited rotationrange. Said limited rotation range may be altered by moving a key guide in one of thecooperative rotation restriction portions. A first release mechanism comprising a triggerportion which extends from the handle and a detent which engages a detent opening inthe base portion requires depression of the trigger portion before rotation of the handleto an unlatched position. The detent mechanism is within the handle and a cap containedand encloses in the detent mechanism. The cap portion has a bore which receives asecond release mechanism which has a shaft portion that may be exteriorly manipulatedto move an obstructing member into and out of an obstructing relation with the detent.Thus, the second release mechanism must be manipulated to allow release of the triggerportion which must then be depressed to allow rotation of the handle. The cap portion issecured in the handle by screws or other threaded members extending from the handlebase portion interface into the cap.
