A plug assembly including a plug, a sidebar movably mounted on the plug, and a plurality of rack pins seated in the plug. The sidebar is biased to an outer position in which the sidebar extends beyond an outer surface of the plug. Each rack pin includes a key-following leg and a sidebar-engaging leg. The sidebar-engaging leg includes at least one true gate. When a true gate of each rack pin is aligned with the sidebar, the sidebar is free to move radially inward to an inner position.

Modular lock plug

A system including a lock class having a plurality of lock families, with each lock family including a plurality of lock cylinders. Each of the lock families has a control pin location which is different from the control pin location of another of the lock families within the lock class. Each of the lock cylinders generally includes a shell, a plug rotatably mounted in the shell, and a control ring rotatably mounted on the plug at the control pin location of the lock family of which the lock cylinder is a member, and a control pin operable to selectively couple the plug with the control ring. Each lock family may be associated with a control key family. Each control key family may include a plurality of control keys, each of which may have a control bitting configured to urge control pins of the associated lock family to a coupling position.

Lock cylinders and control keys

An exemplary lock cylinder includes a shell, a plug positioned in the shell, and a locking assembly. The locking assembly is configured to prevent rotation of the plug when no key is inserted, and to permit rotation of the plug upon insertion of any of a plurality of keys having different bitting profiles. The locking assembly may further be configured to prevent key extraction when the plug is in a rotated position.

Lockdown cylinder locks

A plug assembly including a plug, a sidebar movably mounted on the plug, and a plurality rack pins seated in the plug. The sidebar is biased to an outer position in which the sidebar extends beyond an outer surface, of the plug. Each rack pin is a single-piece unitary structure including a key-following leg and a sidebar-engaging leg. The sidebar engaging leg includes at least one true, gate and a plurality of false gates. When a true gate of each rack pin is aligned with the sidebar, the sidebar is free to move radially inward to an inner position.

An actuator assembly including a mounting device, a manual actuator rotatably mounted on the mounting device, and a cutting mechanism. The cutting mechanism is disposed in a gap that is formed between the manual actuator and the mounting device. The cutting mechanism is structured to cut a ligature inserted into the gap.

Anti-ligature actuators

An exemplary locking cartridge includes a generally cylindrical housing, first and second plates, and a sliding member. The plates are rotatable with respect to the housing, and at least one of the plates is movable in the axial direction of the housing. The housing and the movable plate include cam surfaces that interact to cause the movable plate to move toward the other plate when the movable plate is rotated. The sliding member is slidingly coupled to one of the plates and operable in a blocked state in which the sliding member resists axial motion of the movable plate, and an unblocked state in which the sliding member does not resist axial motion of the movable plate.

Lock plug including modular cartridges

In an exemplary embodiment, a plug assembly includes a plug body, a sidebar, a cover plate, and a plurality of rack pins positioned in the plug assembly. A first portion of the sidebar is positioned in the plug and a second portion protrudes beyond the outer surface of the plug body. The rack pins are configured to selectably resist and permit radially inward motion of the sidebar. The cover plate is operable to selectably retain the rack pins within the plug body.

Lock cylinder including modular plug

A key and lock are provided. The key is provided with a blade having a longitudinal axis. The blade is provided with a channel extending along at least a portion of the blade and along the longitudinal axis. One or more section members is disposed within the channel and coupled to the blade. The section member is capable of movement relative to the blade in the channel. A lock having a keyway and an associated tortuous path to receive the section members as the blade is inserted in the keyway is also provided.

Variable section key and lock

A lock cylinder generally including a shell, a plug positioned within the shell, a locking member, and a leaf spring. The plug includes an opening which is aligned with a recess formed in the shell. The locking member is configured to selectively prevent rotation of the plug with respect to the shell. The leaf spring is positioned in the opening and includes a first portion extending radially inward toward the keyway, and a second portion extending radially outward toward the recess. When a key is inserted, a tip of the second portion extends into the recess. When the plug is subsequently rotated, a tapered surface of the recess urges the tip radially inward and into contact with an inner surface of the shell.

Leaf spring lock cylinder

A plug assembly for a lock includes a generally cylindrical plug body that defines a keyway and a generally cylindrical plug housing that rotatably receives the plug body. A plurality of blocking members are housed in the plug body and are movable into the keyway upon rotation of the plug body relative to the plug housing to obstruct the keyway. A key can be provided that is positionable into the keyway, and the blade of the key defines receptacles for receiving the blocking members when the plug body is rotated so that the lock can be unlocked. However, the blocking members prevent rotation of the plug body when a picking tool or unauthorized key is inserted in the keyway since either the blocking members cannot move into the keyway and remain engaged to the plug housing due to the object in the keyway, or obstruct the keyway and prevent insertion of the picking tool.

Key and lock cylinder

A locking cartridge including a housing, first and second plates rotatably mounted in the housing, a blocking member, and a movable member. The cartridge also includes a cam interface which urges the first plate toward the second plate when the plates are rotated. The blocking member is configured to move among a blocking position and an unblocking position in response to engagement with a first cut on a key. When in the blocking position, the blocking member blocks the first plate from moving toward the second plate. With the second plate blocked from moving toward the first plate, the cam interface prevents rotation of the first plate. The movable member is configured to move among a first position and a second position in response to engagement with a second cut on the key. In certain embodiments, the movable member may be a control pin or a second blocking member.

Locking cartridges

Systems, methods and devices relating to lock assemblies for doors are disclosed. The lock assemblies include an end cap that couples a tail piece, cam or other latch operating mechanism to the plug of the lock assembly so that the latch operating mechanism rotates with rotation of the plug to operate a latch. The end cap includes a plug engaging portion that is configured to interfit with an end cap receiving portion of the plug to axially and rotatably fix the end cap to the plug.

End caps for lock cylinders

A plug assembly including, a plug, a sidebar movably mounted on the plug, and a plurality of rack pins seated in the plug. The sidebar is biased to an outer position in which the sidebar extends beyond an outer surface of the plug. Each rack pin is a single-piece unitary structure including a key-following leg, and a sidebar-engaging leg. The sidebar-engaging leg includes at least one true gate and a plurality of false gates. When a true gate of each rack pin is aligned with the sidebar, the sidebar is free to move radially inward to an inner position.
