A disc tumbler lock assembly includes a lock cylinder inserted in a lock cylinder chamber of a lock housing, the lock cylinder being formed with a disc cavity and a lug groove; inner locking discs each having a first key hole with a first locking tooth therein, a side of each inner locking disc being formed with a first latch notch and a first lug located in the lug groove; outer locking discs each having an inner locking disc room and a second key hole with a second locking tooth therein, a side of each outer locking disc being formed with a second latch notch and a second lug located in the lug groove; the inner and outer locking discs being arranged in pairs, a corresponding one of the inner locking discs being disposed in the inner locking disc room of a corresponding one of the outer locking discs.

A rekeyable master keyable lock includes a plurality of key followers, a plurality of user racks and a plurality of master racks. One user rack and one master rack are associated with each key follower and are configured to be selectively disengaged from, and reengaged with, the key follower. When the user racks are disenggaged from the key follower, the valid user key can be replaced with a new user key. Reengaging the user racks with the key followers rekeys the lock cylinder to the new user key and invalidates the original user key. Similar functionality applies to rekeying the master key. Either the user key or the master key can be rekeyed without rekeying the other.

The present disclosure provides for a lock cylinder having a rotatable spindle with at least one disc and at least one wafer housing rotatingly engaged therewith. A slidable wafer is carried on the wafer housing. A locking bar is operable to prevent rotation of the lock cylinder in a locked position and permit rotation of the lock cylinder in an unlocked position.

A housing configured to accept a rekeyable lock core for use in lockable enclosures. The housing is configured to use a lock core that is designed for deadbolt and door lever/knob operation. The housing allows a rekeyable lock cylinder to be used in one's home as well as other enclosure enclosures. A common key may therefore be used for all devices as the lock core is of a rekeyable design.

Embodiments of the present invention are directed to merchandise display systems and methods for displaying an article of merchandise. In one example, the system includes a sensor configured to be secured to the article of merchandise. The system also includes a base configured to removably support the sensor thereon. The base includes a lock mechanism configured to lock the sensor to the base.

A gun mounting lock and a method of using the same to secure a gun to a support surface. The gun mounting lock includes first and second arms positioned opposite each other and a ratchet assembly positioned between lower ends of the arms. The ratchet assembly engages gears provided on the lower ends of the arms. When the assembly is pushed downwardly by placing part of a gun thereon, the downward movement of the assembly causes the two arms to pivot towards each other simultaneously, capturing the gun between the arms and the assembly. The assembly is locked against movement in the reverse direction by a pin of a solenoid contacting a toothed flange on one of the arms. The assembly can be unlocked using a key or by providing power to the solenoid. The gun mounting lock housing is adjustably engaged with a track mounted on the support surface.

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 bridge tumbler lock has tumblers that both slide and pivot, with their motion controlled by pairs of key interfaces. A sidebar is released to permit lock opening movement when all tumblers are in their correct positions. This results in a lock that is resistant to release of information due to partially correct key combinations occurring in the course of a lock picking attempt and thus enables enhanced security in an economical, effective lock construction.

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 vehicle includes a chassis, a cab, a cargo body, and a window assembly. The cab is coupled to the chassis. The cargo body is coupled to the chassis, rearward of the cab. The window assembly is positioned on a door of the cab and includes a first window, a second window, and a seal. The first window is fixedly coupled with one or more support columns. The second window is translatably coupled with the first window, and is translatable between a first position and a second position. The seal extends between the first window and the second window. The seal is fixedly coupled with the first window and is configured to sealingly engage the second window when the second window is in the first position.
