A patch lock assembly releasably secures a glass door to an adjacent glass panel in a locked orientation. The patch lock assembly comprises a latch adapter housing, a strike adapter housing, and first and second power supply adapter housings. The latch adapter housing may interchangeably receive one of any number of various latch mechanisms without requiring further modification of the door. The strike adapter housing may interchangeably receive one of any number of various strikes, including electric strikes, without requiring further modification of the door. Respective power supply adapter housings may be coupled to each latch adapter housing and strike adapter housing. The power supply adapters include a power source and control unit to provide the necessary power to operate the latch and strike. Various interlocking features may be incorporated in the design to resist unwanted movement of the patch lock assembly relative to the glass panel.

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.

A key or a key blank for a disk cylinder having a plurality of rotatably supported disk tumblers has a key shaft having a shaft cross-section that comprises a first end section, a second end section and a connection section along a longitudinal axis, the connection section connecting the first end section and the second end section to one another. The connection section is narrower than the two end sections and has two longitudinal edges that are aligned in parallel with one another and that extend obliquely to the longitudinal axis of the shaft cross-section between the two end sections.

Cylindrical locks and more specifically a set of profile members in combination with a rotatable cylindrical key plug have a longitudinal keyway with a profile corresponding to an associated key. Each profile member is accommodated in an associated cavity in the key plug at a lateral side of the keyway so as to form a lateral part thereof. The profile members have a non-circular cross-section and are non-rotatably mounted in the associated cavities at a location adjacent to the keyway. A portion of each profile member has a profiled surface portion facing inwards toward the opposite lateral side of the keyway, the profiled surface portion having, in a plane being transversal to a longitudinal axis of the key plug, a specific profile section defining a local, lateral part of the keyway. An associated key, and a method to manufacture a cylindrical key plug with such profile members are also disclosed.

A key including at least one coding cavity (55) defining a hollow geometry for coding the key. The geometry includes at least one internal undercut (60a, 60b). The lock for validating a key comprises blocking means (21, 22) coupled to a driving part (14) and validating means (25, 26) which are coupled to the blocking means so as to change the state of the blocking means when the key used with the lock has a correct coding. The validating means (25, 26) protrude at least partially into the key cavity of the lock in order to introduce the validating means at least partially into the coding cavity (55) of the key and to sense the inner face of the coding cavity.

A key or a key blank for a disk cylinder having a plurality of rotatably supported disk tumblers has a key shaft having a shaft cross-section that comprises a first end section, a second end section and a connection section along a longitudinal axis, said connection section connecting the first end section and the second end section to one another. The connection section is narrower than the two end sections and has two longitudinal edges that are aligned in parallel with one another and that extend obliquely to the longitudinal axis of the shaft cross-section between the two end sections.

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.

Locks for use with pest-control devices such as bait stations or other loadable devices, kits that include a lock and key, and pest control devices that include a lock.

A flat key for a locking cylinder has substantially flat and approximately parallel flat key sides, a key rear section, and a key front section opposite thereto. The key front section has a toothing for positioning tumbler pins divided into core pins and housing pins and which are spring-loaded against the key front section in the direction of the key rear section and into corresponding bores. Grooves in the form of profiled variation elements and profiled guiding elements are provided in the flat sides of the flat key, wherein at least two grooves of one flat side of the flat key, which are preferably part of the profiled guide, overlap and are undercut in opposite directions. A depression is provided in the outer flank of at least one of the two grooves, preferably both grooves, at least one region of the depression not being visible from the side.
