  • Patent number: 9708839
    Abstract: A door locking device is applied to an electronic apparatus including a hinged door arranged in an opening portion of a casing. The door locking device includes a key cylinder and a pivot hook. When the door is closed and a movable element of the key cylinder is at a locked position, the pivot hook is caught on the casing to prevent the door from being opened. The door locking device further includes a rod member crank-coupled to the movable element of the key cylinder on an inner side of the door and configured to be displaced by interlocking with the movable element. When the door is closed and the movable element is at the locked position, a distal end (roller) of the rod member is held in contact with a rod receiving surface formed in the casing. Thus, the rod member keeps a closed state of the door.

  • Patent number: 9271549
    Abstract: A bracelet includes a plurality of links assembled in an articulated manner using pins. Each pin passes through interlocking parts of links in which a cylindrical passage is arranged where a pin can slide relatively freely. In order to ensure the position of the pin once the links have been assembled, a locking element is arranged in a cavity made in one of the links so as to partially intersect the passage in which the pin is arranged. This pin includes a groove, which is penetrated by an external part of the locking element when the element is in the closed position. Pressing on the locking element, then rotating it by an angle of 90°, releases the external part of the pin groove so that the pin is then released.

  • Patent number: 8960372
    Abstract: An apparatus for use with an elevator car is operable to selectively lock an elevator car door. The apparatus verifies that the elevator car door is closed, locks the elevator car door, and verifies that a lock is engaged. Once conditions are met, the apparatus signals an elevator controller that the elevator car can move through a hoistway. The apparatus further ensures that passengers can safely disembark from the elevator car by detecting the position of the elevator car relative to a designated landing zone within the hoistway, and confirming the elevator car is stopped at a landing zone prior to disengaging the lock. The apparatus thus ensures that the elevator car door remains closed while the elevator car is in motion or between landing zones.

    Abstract: The lock has a rotatable latch. The latch is mounted for movement between a position wherein it engages a fixed part of the vehicle to secure the door in the closed position and a position remote from the fixed part of the vehicle such that the door can be opened. A latch movement preventing member is moveable relative to the latch between a position remote from the path of movement of the latch, wherein the latch is free to disengage the fixed part of the truck, and a position intersecting the path of the latch, wherein movement of the latch to disengage the fixed part of the truck is blocked. A pair of magnets are oriented to force the member to move from its remote position, against the action of a spring, to its intersecting position, to prevent the latch from disengaging the fixed part of the truck.

  • Patent number: 6920770
    Abstract: A plunger lock assembly having a removable core is provided. The lock assembly includes a housing defining a first longitudinal bore and a barrel reciprocably mounted within the first longitudinal bore between an advanced position and a retracted position. The barrel defines a second longitudinal bore and is operably associated with a plunger. A core is removable mounted within the second longitudinal bore of the barrel and includes a key slot for receiving an operating key. A drive member is positioned within the second longitudinal bore and is movable from an unlocked position to a locked position by operation of the operating key. A retainer assembly is operably associated with the drive member to axially retain the drive member within the second longitudinal bore such that the core is removable from the second longitudinal bore independently of the drive member. A biasing member is provided for urging the barrel towards the retracted position.

  • Publication number: 20040035159
    Abstract: A lock includes a lock housing (3), a bolt (20) which is moveable in the lock housing between an inwardly withdrawn and an outwardly extended position and which includes a weakened region (36). The lock also includes a blocking element (5) fixedly arranged in the lock housing, an interlocking device (12, 14, 16), and a bolt-carried abutment element (34) which is adapted to coact with the interlocking device (16). When the bolt is subjected to an outer force that exceeds a generally predetermined force, the bolt will deform in the weakened region (36) so that movement of the bolt between the outwardly extended and inwardly withdrawn positions will be blocked by the fixedly mounted blocking element (5).

  • Patent number: 6477872
    Abstract: A storage unit door locking system is shown for securing and locking a storage unit door and preventing forced entry wherein the door is attached to a doorjamb. The locking system has a door plate which is mounted to the door with an extension plate that extends beyond the edge of the door and abuts the front face of the doorjamb when the door is closed. A sliding bolt slidably mounted to, but spaced apart from, the door plate slides behind the doorjamb trapping the doorjambs between the extension plate and the sliding bolt. A recessed lock is inserted through matching aligned holes in the extension plate, doorjamb, and sliding bolt and locked. This physically locks the doorjamb to the extension plate and sliding bolt which prevents forced entry with the use of crowbars or other prying devices normally used to separate the doorjamb from the door and locks contained thereon.
