An electronic cylinder lock has a main body. The main body is provided with a rotary cam. A first shaft is connected to the rotary cam. The first shaft has a first engaging portion. The main body is provided with a second shaft. The second shaft has a second engaging portion. A control lever is connected to the second shaft. A driving source is connected to the control lever. The driving source can drive the control lever to pull the second shaft to approach the first shaft, so that the second engaging portion is engaged with the first engaging portion, thereby improving the joint stability between the second engaging portion and the first engaging portion.

A smart lock for securing a door comprising: a housing mountable to the door; an actuator within the housing configured to actuate a lock mechanism between a locked position and an unlocked position, the lock mechanism including a latch bolt with an angled front face, the latch bolt configured to be retractable against a biasing force provided by a biasing means such that the door is closeable when the lock mechanism is in the locked position; and a receiver within the housing configured to wirelessly receive a signal to control operation of the actuator; a sensor mountable exclusively to the door so as to generate a signal indicative of the door beginning to move; a controller arranged to receive the signal indicative of the door beginning to move, the controller configured to control the actuator to actuate the lock mechanism in response to the signal indicative of the door beginning to move.

The present invention relates to an electromechanical lock assembly (1) comprising a lock body (15), a lock core (17), a lock bolt operating member (19), and an electronic access control device. The electromechanical lock assembly further comprises an annular element (27) which is rotatably and axially displaceably mounted on said lock core (17), a coupling device (25) arranged to communicate with said electronic access control device and, upon the insertion of an appropriate key (65) in a key receptacle (37) of the lock core (17), rotationally lock the annular element (27) to the lock core (17), thereby enabling rotation of the lock core (17) in a first direction and thereby enabling unlocking of a lock (3) with said appropriate key (65), and a blocking arrangement (63) arranged to prevent unauthorized unlocking of said lock (3).

An actuating device (12) comprising an actuating element (14); an electric generator (16); and an electromechanical coupling device (18) configured to adopt a decoupled state, for decoupling the actuating element (14) from a locking member (22), and a coupled state, for coupling the actuating element (14) to the locking member (22); wherein the coupling device (18) comprises a blocker (26), a holder (38) and a release mechanism (40); wherein the holder (38) is arranged to adopt a holding position, in which the holder (38) holds the blocker (26), when the coupling device (18) adopts the coupled state; wherein the holder (38) is arranged to adopt a released position, in which the holder (38) does not hold the blocker (26), when the coupling device (18) adopts the decoupled state; and wherein the release mechanism (40) is arranged to mechanically force the holder (38) from the holding position to the released position by manual rotation of the actuating element (14) about the actuating axis (20).

An electro-mechanical lock for use with a lock device having a locked state and an unlocked state is disclosed. The electro-mechanical lock incorporates an actuation motor susceptible to lockdown and features a variety of lockdown mitigation structures and arrangements to combat the same.

An electronic cylindrical lock has a main body. The main body includes a slide member. The main body further includes a first clutch unit and a second clutch unit to drive the slide member. The first clutch unit and the second clutch unit are connected with a first handle and a second handle, respectively. The main body further includes a control unit for controlling the first clutch unit and the second clutch unit to be engaged or disengaged, so as to selectively allow the first handle and the second handle to drive the lock tongue, or selectively allow the first handle and the second handle not to drive the lock tongue.

A lock assembly is disclosed to lock a moveable structure to a fixed structure. The lock assembly includes an electric actuator operable to move a locking lug between first and second axial positions to correspond with a locked and unlocked configuration of the lock assembly. A resilient member can couple the locking lug to the electric actuator and drive the locking lug between the first and second positions.

A lock cylinder (110) is provided adapted to be installed in a lock (100) comprising a lock bolt (120) for driving the lock bolt. Said lock cylinder comprises a cylinder housing (200), and a revolving plug (115) comprising a rotor element (275) adapted to rotate with respect to the cylinder housing about a rotation axis (R) within a rotation support (510; 520), and a driving tooth (280) for the lock bolt comprising an engage portion (282) adapted to engage the lock bolt, said driving tooth being rotatable about the rotation axis together with the rotor element and being coupled to the rotor element in such a way the operative distance between the engage portion of the driving tooth (280) and the rotation axis (R) varies, while rotating about the rotation axis, as a function of the rotation angle of the rotor element (275) with respect to the cylinder housing (200). When the lock cylinder (110) is installed in the lock, said operative distance has one among a plurality of first values when the rotation angle of the rotor element belongs to a first angular interval (A I) corresponding to a position of the engage portion of the driving tooth that is proximal to the lock bolt (120); and said operative distance has one among a plurality of second values when the rotation angle belongs to a second angular interval (A2) corresponding to a position of the engage portion of the driving tooth that is distal to the lock bolt, each of said first values being higher than each of said second values. When the lock cylinder (110) is installed in the lock (100), the lock cylinder is located below the lock bolt along a first direction (y) substantially perpendicular to the rotation axis (R). the driving tooth (280) is slidingly housed within a seat (550) which is radially provided in the rotation element (275) and which defines at least one side opening of the rotor element (275) perpendicular to the rotation axis (R).—The driving tooth (280) is provided with at least one engage element (590) which protrudes from a side opening along a direction parallel to the rotation axis, and adapted to slidingly engage guide profiles (524, 620) provided on the rotation support (510; 520), said guide profiles (524, 620) defining for said at least one engage element (590) an overall guide profile having an eccentric shape arranged to support from below along said first direction said at least one engage element (590)

The embodiments presented within provide methods, devices, and systems that improve access control through the use of smart cylinder locks. In one embodiment, a smart cylinder may perform a process including receiving a key, emitting an energy source of electromagnetic radiation; detecting a change in the energy source due to a physical property of the key, determining the physical property of the key from the change in the energy source, comparing the physical property with a predetermined value, and engaging a mechanism operatively coupled to a locking device that allows the locking device to lock or unlock when the physical property matches the predetermined value.
