  • Patent number: 9447608
    Abstract: 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.

  • Patent number: 7275401
    Abstract: The invention relates to a key switch with at least one turn-key switching position comprising a cylindrical lock adapted to perform a translation upon key authorization. The aim is to present a key switch being capable of allowing key hierarchies as well as the withdrawal of the key in particular switching positions. For this purpose the key switch also comprises a lock holder adapted to host the translation of a cylindrical lock in respect to the lock holder along a common rotational axis and the cylindrical lock being form-locking with the lock holder for rotations around the rotational axis. The user is able to employ the turning key movement for the selection of a switching position and an outward and inward linear translation of the key to lock or unlock a switching position.

  • Patent number: 7205492
    Abstract: A push button actuator unit has a housing which defines a through passage that extends along an axis of the housing, and a slot that extends in a plane which transversely intersects the axis and communicates with the passage for supporting in the housing-defined slot a disc-shaped member having a central opening that aligns with the passage. Movable in the aligned passage and opening is a push button sub-assembly of the unit which includes a front element that, when depressed rearwardly, may cause a rear element of the push button sub-assembly to extend rearwardly from the housing to release a latch or to operate a switch or the like. If the unit is to be lockable, an optional locking mechanism is added to the elements of the push button sub-assembly to selectively drivingly connect the front and rear elements so that depression of the front element will cause rearward extension of the rear element only when the unit is unlocked.

  • Patent number: 7171833
    Abstract: The cylinder lock has a housing, a fixed hollow cylinder, a rotatable hollow cylinder and a locking bar. The locking bar has a mounting portion with planes, shoulders and a resilient element mounted around the mounting portion. The rotatable hollow cylinder has a non-circular mounting hole corresponding to and held slidably the mounting portion of the locking bar to enable synchronous rotation and relative sliding movement of the rotatable hollow cylinder and the locking bar to make the cylinder lock active. By the modification of the locking bar and the rotatable hollow cylinder, the structure of the cylinder lock is effectively simplified and the fabrication of the cylinder lock is easy.

  • 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.

  • Patent number: 6899362
    Abstract: A linkage assembly includes a frame, an arm movement coordinating member slidably supported by the frame, and a pair of arms pivotally connected to the frame and connected to the coordinating member to ensure that the arms pivot in unison when the coordinating member is slided relative to the frame by depressing a push button that is connected to the frame for translation relative thereto. Either of the arms can be link-connected to a latch assembly for operating either a single latch assembly or for concurrently operating a pair of latch assemblies in response to depression of the push button. An optional emergency release cable may connect with the arm movement coordinating member to facilitate latch operation from inside a tonneau cover of a pickup truck or the like that is held closed by the latch or latches.

  • Patent number: 6782725
    Abstract: A push button lock. The push button lock has a main housing with an aperture formed therethrough, a plunger which is axially moveable in the aperture of the main housing, and a ball retainer positioned in the aperture of the main housing. The ball retainer has a central aperture formed therein through which the plunger extends and a protrusion. Balls are placed on the ball retainer. An actuator is located in the main housing aperture above the ball retainer and is rotatable to an open position, wherein the actuator is in position to be pushed down to prevent the balls from moving away from the plunger shaft and thereby prevent the plunger shaft from moving relative to the ball retainer, and a locked position, wherein the balls are not retained against the plunger shaft and the plunger shaft can move relative to the balls retainer. A lock button having a lock housing and a lock cylinder is provided, with the lock cylinder being adapted to turn the actuator from the opened position to the locked position.
