A handle assembly includes a lock cylinder of a selected one of a first standard or a different second standard. A tail piece extends from the lock cylinder. The handle assembly also includes a vertical tubular member, a horizontal tubular member and a transition plate. The transition plate is disposed within the vertical tubular member and is moveable between a first position and a different second position. The transition plate accommodates installation of the lock cylinder of the first standard when in the first position and installation of the lock cylinder of the second standard when in the second position. A mechanical linkage is coupled to the tail piece and effects movement of a locking bolt in response to turning of a key in the lock cylinder.

A door assembly for selectively interlocking opposing doors each pivotably mounted at a hinge side thereof to a door frame so as to both open and close in the same direction includes a door handle assembly mounted to one door at a latch side thereof opposite the hinge side and carrying a first plurality of magnets, and another door handle assembly mounted to the other door at a latch side thereof opposite the hinge side and carrying a second plurality of magnets. The door handle assemblies are arranged relative to each other with the first and second pluralities of magnets aligned such each aligned pair of the first and second pluralities of magnets have opposite magnetic polarities, and the aligned first and second pluralities of magnets magnetically couple to each other as the door handle assemblies are brought into contact with each other.

A lock having a rotatable auxiliary positioning structure is adapted to connect with a latch element which includes a drive orifice, and the lock contains: a first locking assembly and a second locking assembly. The first locking assembly includes a transmission unit and a guide seat, the guide seat has at least one guiding extension. The second locking assembly includes a driving element, and a connecting position is defined between the first locking assembly and the second locking assembly in a rotatable direction. At least one of the transmission unit and the driving element is rotatably received in and drives the drive orifice of the latch element, the at least one guiding extension is configured to be connected with the latch element and to guide the first locking assembly to be positioned on the connecting position along the rotatable direction opposite to the latch element.

An electronic lock cylinder that may be a direct replacement for a European-style standard cylinder is disclosed. The lock cylinder may include a core, a first shaft rotatably mounted in the core, and a second shaft rotatably mounted in the core and coaxial with the first shaft. A first cam and a second cam may be each rotatably mounted in the core and coaxial with the first shaft. The first cam may include a first lug and the second cam may include a second lug, where the first lug and the second lug may each be coupled to a deadbolt. A clutch may be disposed on the first shaft and shiftable from a first position to a second position, and a motor may be disposed in the core and operatively coupled to the clutch and configured to shift the clutch from the first position to the second position. When the clutch is in the first position, the first shaft is operatively coupled to the first cam, and the second shaft is decoupled from both the first cam and the second cam, when the clutch is in the second position, both the first shaft and the second shaft are operatively coupled to the second cam. The lock includes a first shaft rotatably mounted in the core and a second shaft rotatably mounted in the core and coaxial with the first shaft. A clutch is disposed on the first shaft and rotationally fixed to the first shaft but axially shiftable. The lock also includes a slider with a finger, where the finger is engaged with the clutch, and a motor is configured to shift the slider axially between a first position and a second position. In the first position, the clutch is disengaged from the second shaft, and in the second position, the clutch is engaged with the second shaft, such that rotation of the first shaft causes rotation of the second shaft.

A door-operating assembly has an operating device having a device housing and a device magnet and rotatable in the housing about a first axis between a first functional position and a second functional position, and a status indicator that is coupled with the operating device and has an indicator housing and an indicator magnet movable in the indicator housing along the first axis between a first display position and a second display position. The magnets are so oriented that rotation of the device magnet about the first axis from the respective first functional position into the respective second functional position displaces the indicator magnet axially of the first axis from the first display position into the second display position.
