A lock assembly comprising a throw bolt, a bolt holder and a bolt keeper. The bolt comprises a cutting barrier and a bolt casing, the bolt casing being more corrosion-resistant than the cutting barrier, and the cutting barrier being more abrasion-resistant that the bolt casing. When assembled, the cutting barrier will be enclosed within the bolt casing.

A lock with an extended bolt throw comprising a back plate, a locking bolt having a rack gear profile on at least a portion of one side, slidably mounted to the back plate movable between a first position and a second position. An accelerator gear mounted to the back plate movable along an arcuate path between a first and second position. The accelerator gear comprising a curved edge having teeth which engage the rack gear profile of the locking bolt, and an opposing edge having a centrally located notch for engagement of a cam of a lock cylinder. Wherein as the cam rotates about the lock cylinder it engages the notch and urges the accelerator gear from the first position to the second position, which urges the locking bolt from the first position to the second position.

A lock for an aircraft door. The lock includes an outer shell having an inner cavity. A core is rotatably mounted within the inner cavity to rotate about an axis of the core. The core has a keyhole extending through the core from a first end of the core for receiving a key therein, to an opposed second end of the core. The keyhole defines an air leakage path through the core. A cam has a cam arm mounted about the core and is rotatable therewith. The second end of the core protrudes from the cam. A cover is attached to the second end of the core. The cover blocks the keyhole at the second end of the core and obstructing the air leakage path. An aircraft door, methods, and a retrofit kit are also disclosed.

The lock according to the invention is meant for locking cabinets, vaults and different machines. The lock has a lock frame, which comprises a bolt. A lock cylinder has been arranged in connection with the lock frame. The lock frame further comprises a power transmission mechanism between the lock cylinder and the bolt. The power transmission mechanism comprises a transmission lever and a latch. The transmission lever additionally comprises a retaining protrusion. The bolt comprises a locking pin and the lock frame additionally comprises a hole for the locking pin. The lock is arranged to allow movement of the lock cylinder and the power transmission mechanism in the direction of the longitudinal axis of the lock cylinder due to an external hit or drilling of the lock cylinder, whereby the movement in the direction of the longitudinal axis moves the retaining protrusion away from the locking pin. Thus, the end of the locking pin moves into the hole in the frame.

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 pick resistant lock assembly has two lock sections which can be opened in two stages separated by time using a single key. The first locked section is rotated slightly by the use of the key, whereupon the second locked member is released from being locked by the isolated stack of locking pin tumblers and is then also made connective to the first lock section by a gear connective to the lock housing such that the first lock section and second lock section can then be rotated together, but only if the selectively machined key had been used in the beginning, else further rotation of either member is prevented by the multiple stacks of locking pin tumblers that are common to both.

An exemplary trim assembly comprises an escutcheon, a drive spindle, a lock mechanism, a cam mechanism, and a driver. The drive spindle is mounted to the escutcheon for rotation about a longitudinal axis. The lock mechanism includes a lock gear movably mounted in the escutcheon. The cam mechanism includes a first cam defined by the escutcheon and a second cam defined by the lock gear. The driver is operable to rotate the lock gear between a first rotational position and a second rotational position. The cam mechanism is configured to longitudinally drive the lock gear from a first longitudinal position to a second longitudinal position as the lock gear rotates from the first rotational position to the second rotational position. Movement of the lock gear between the first longitudinal position and the second longitudinal position transitions the lock mechanism between a locked state and an unlocked state.

A lock cylinder includes a housing, in which a sleeve having a cylinder core accommodated therein is rotatably supported. The cylinder core has spring-loaded tumblers forming a form closure with recesses arranged in the sleeve when a key engaging the tumblers is removed. Inside the housing, the sleeve is coupled to a coupling element by means of a disengaging sleeve. The coupling element is supported inside the housing and connected to a bearing in a rotationally-fixed manner. The bearing supports an output element. At least one of the sleeve and the coupling element forms a form closure with the bearing to block the rotation of the output element if an improper object is used in operative connection with the cylinder core.
