Abstract:
A combination of a disc tumbler cylinder lock and a key. The disc tumbler cylinder lock includes rotation limiting device for the key and a guiding element. The key includes grooves for the guiding element, which has two rails making up some of said rotation limiting device, and both of the rails include at least one limiter protrusion arranged to facing inward in the disc tumbler cylinder lock. The key includes at least one recess for the limiter protrusions. The rotation limiting device further includes a front guide having the rails in association therewith. The front guide and the rails are arranged to allow the key, which is in a basic position in the disc tumbler cylinder lock, to be turned for releasing the locking of the disc tumbler cylinder lock.
Abstract:
The cylinder lock according to the invention includes a body and, inside it, an inner cylinder unit provided with an inner cylinder. The cylinder lock also includes a generator for generating electricity from the movement of a key inserted in the cylinder lock. The electricity generated is used to identify the key, and the electricity generated is also used in the electric device if opening the cylinder lock is allowed on the basis of the identification of the key. In connection with the generator are also generator shaft system, a channel axis and transmission parts from the channel axis to the generator.
Abstract:
A lock assembly includes a cylinder portion having an open end which receives a key. The assembly further includes a stem portion operatively connected to the cylinder portion and torsion spring operatively attached to the first and second lock portions, wherein the stem portion is capable of biased rotational movement independent of the cylinder portion. The lock assembly also includes at least one locking ball received atop the stem portion, the at least one locking ball being extendable and retractable from at least one slot in a housing of the lock assembly. A compression spring received about the stem portion biases the at least one locking ball towards a distal end of the stem. During installation into a lock receptacle, the locking ball is urged radially against the stem, causing the stem to rotate against the bias of the torsion spring, as well as urged axially rearward within the slot against the bias of the compression spring. In this position, the locking ball is positioned above a relieved area of the stem, permitting the locking ball to retract into the housing.
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.
Abstract:
A lock cylinder comprises a cylinder housing, a disk housing rotatably supported about a cylinder axis in the cylinder housing and a plurality of rotatably supported disk tumblers arranged along the cylinder axis in the disk housing, wherein each disk tumbler has a reception opening for a key, a blocking cut-out at the outer periphery for an at least partial reception of a blocking pin aligned in parallel with the cylinder axis and a fixing cut-out provided offset from the blocking cut-out at the outer periphery for an at least partial reception of a core pin aligned in parallel with the cylinder axis. The disk tumblers are rotatable from a starting position with a removed key into an end sorting position by a rotation of the introduced key in the latching direction, in which end sorting position the blocking cut-outs of all the disk tumblers are oriented in alignment with one another, viewed in the direction of the cylinder axis. The fixing cut-outs of all the disk tumblers are oriented in alignment with one another in the end sorting position, viewed in the direction of the cylinder axis. The lock cylinder is adapted such that, on a further rotation of the disk tumblers out of the end sorting position in the unlatching direction, the core pin first engages into the fixing cut-outs and the blocking pin only then engages into the blocking cut-outs.
Abstract:
The invention relates to a tumbler disc of a disc tumbler cylinder lock. It is formed by a substantially circular disc (1) having a central hole (2) that corresponds to the cross-sectional profile of the key for that lock and a limiter (3). According to the invention, the tumbler disc (1) includes a groove (4) that extends inwards from the outer periphery thereof and deviates from the radial direction of the tumbler disc with a width that is smaller than the width of the locking bar of the lock.
Abstract:
An electromechanical cable lock system comprising an electromechanical locking mechanism including a cable having at least one plug end receivable in the locking mechanism and a plurality of slidable locking plates engageable with the plug in said locking mechanism. At least one of the locking plates is capable of movement in a first direction different from the movement of a second of said locking plates in a second direction. The locking plates are driven by a motor-driven cam mechanism. The system includes a card reader or other credential verifying device and an electronic controller for activating the locking mechanism, The system also includes a barrel lock for over-riding the electronic controller. A plurality of features can detect and alarm in the event of tampering or unauthorized entry.
Abstract:
Some embodiments include electronic circuitry for an electronic lock. The electronic circuitry can include: an antenna configured to receive a wireless signal; a communication processor, coupled to the antenna, configured to decode the wireless signal to ascertain a command to lock or unlock the electronic lock and to authenticate a source of the wireless signal; an energy storage configured to store electrical energy; a motor switch configured to drive a motor clockwise or counterclockwise, powered by the energy storage, depending on a control signal, wherein the motor switch is configured to drive the motor for a short burst of time; and a controller, coupled to the energy storage capacitor and the motor switch, configured to monitor electrical charge left in the energy storage and to output the control signal that corresponds to the command to lock or unlock the electronic lock.

Abstract:
An electromechanical lock includes a spring-biased cylinder plug return mechanism for automatically rotating the rotatable plug to a home position after the plug has been rotated from the home position and thereafter released. In one embodiment, the cylinder plug return mechanism comprises a torsional spring coupled to the plug, In a second embodiment, the cylinder plug return mechanism comprises a slider that is coupled to the plug so that rotation of the plug moves the slider, thereby increasing the potential energy in a return spring, and when the plug is released, the increase potential energy is released by moving the slider, and the coupling between the slider and the plug causes the plug to rotate back to a home position.
