Abstract: An adapter for either a handle set or a lever set door lever is equipped with a pair of springs to provide a pre-load on the spindle. The pre-load prevents sagging of the lever due to the large mass of the lever. A sleeve in the adapter is formed out of a compressible material that accepts the spindle in a press-fit configuration. This allows for greater manufacturing tolerances while still providing a solid and secure engagement between the spindle and the adapter. As a result, any free play in the lever is eliminated and the lever is maintained in a horizontal, home position when the lever is not in use. Following use through rotation of the lever, the springs promptly return the lever back to the home position while the sleeve prevents any slop or free-play in the lever's motion.

A release is incorporated in the latch bolt and allows the latch bolt to rotate when the release engages the door strike as the door closes. An additional unlocking mechanism may be provided for retracting the latch bolt from the outside of the door independently of the crossbar. A firelocking mechanism may be incorporated in the latch bolt to secure the latch bolt when a fire occurs. Two pins with a spring between them are retained by fusible plugs at either end of a bore in the latch bolt, so that the latch bolt operates as a normal lock on the door.

Abstract: A latch mechanism is shown which utilizes a pair of latch dogs pivotally mounted on a base member. Each of the dogs has a curved end region which is adapted to contact a curved work surface of an associated stop member. The dogs are pivotable between a release position in which the curved end regions are apart from the work surfaces to allow relative movement between the base member and stop member and an engaged position in which the curved end regions contact the work surfaces. A positive locking action is achieved by providing the dog end regions with a radius of curvature which matches the radius of curvature of the stop member work surfaces, but offsetting the center point of the radius of curvature of the dogs from the pivot points of the dogs. In this way, the end regions and work surfaces fully mate in the engaged position, but are pulled fully apart when moving to the release position.

Abstract: Deadbolt mechanism for holding a door in a closed position and including a deadbolt pivotally connected to the mechanism housing for movement into and out of that housing to adopt inoperative and operative positions respectively.

The drive between the lock barrel and deadbolt includes a pair of gear segments which engage during the 90.degree. travel of the deadbolt and are otherwise disengaged to permit the lock barrel to rotate free of the deadbolt. The drive also includes a pivoted arm which locates between side walls of the deadbolt and has a laterally extending pin slideably locating within a slot in each of the side walls. When the gear segments are engaged the arm is swung such that a camming action occurs between the pin and cooperating slots whereby the deadbolt is caused to move about its pivot.
