A locking mechanism and a door opening control method are provided for household appliances. The locking mechanism is provided on a front door panel of a door of a cooking machine and used for controlling the opening and closing of the door and includes: a lever which is mounted on the back surface of the front door panel and at least a portion of which protrudes from an opening provided on the front door panel to the front surface of the front door panel; an electromagnet which is mounted on the back surface of the front door panel and may be in a locked or unlocked state with respect to the lever. The locking of the door of the cooking machine may be realized through the cooperation between the electromagnet and the lever. Real-time control of the door may be realized to better ensure safety of the user.

An operating arrangement for at least one motor vehicle latch, in particular a flap operating arrangement for two motor vehicle flap latches placed at a distance from one another and provided with a drive train. Furthermore, a lever arrangement interacting with the drive train is provided. Moreover, there is provided at least one transmission attached to the lever arrangement to act upon the at least one motor vehicle latch. The lever arrangement has an operating lever to act upon the transmission and a locking lever that blocks the operating lever at least when in a “locked” position, wherein the drive train works upon the locking lever.

An electronic lock, including: a power storage device; and photovoltaic cells located on a surface of the electronic lock, the photovoltaic cells being electrically coupled to the power storage device in order to provide a charging current to the power storage device.

The invention relates to a locking device for doors, compartments, and flaps. The stator is equipped with a battery-operated motor and an electronic control unit which acts on the motor. A handle (20) is connected to the rotor (30) so as to transmit a torque and is held on the rotor (30) by a clamping spring (50). The clamping spring (50) has a receiving area for a magnet (60). The process of replacing the battery for the motor is easily facilitated in that the clamping connection between the handle (20) and the rotor (30) is triggered by an external influence on the magnet (60) (FIG. 1).

Electromechanical lock. Actuator (103) comprises drive head (109) rotatable by electric power (160). Access control mechanism (104) comprises driven gear (101) with cogs, and grip mechanism (111). Drive head (109) comprises two pins (210, 212) configured and positioned so that one of pins (210, 212) is in notch between two cogs (220, 222, 224, 226, 228) of driven gear (101). For opening, drive head (109) rotates driven gear (101) to open position (400), by two pins (210, 212) driving cogs (220, 222, 224, 226, 228) and overcoming grip mechanism (111), and thereby setting access control mechanism (104) to be rotatable (152) by user. If external mechanical break-in force (172) is applied, drive head (109) remains stationary by at least one of pins (210, 212) contacting at least one of cogs (220, 222, 224), and by grip mechanism (111) holding driven gear (101) stationary in locked position (200).

The invention relates to an actuating handle (100) for a door with an escutcheon (104) and a handle (102) for actuating a locking device arranged in the door. The handle (102) for actuating the locking device is mounted in the escutcheon (104) rotatably about a first axis of rotation. The actuating handle (100) moreover has a blocking device (106), having a release position in which a rotation of the handle (102) about the first axis of rotation is released, and a blocking position in which a rotation of the handle (102) about the first axis of rotation is blocked by the blocking device (106). The actuating handle (100) moreover has an actuating mechanism (112) for the blocking device (106). According to the invention, it is provided that the actuating mechanism (112) has a sliding element (108) which is displaceable along a circle segment centered around the first axis of rotation, wherein a displacement of the sliding element (108) along the circle segment brings about an actuation of the blocking device (106).

Disclosed is a method of opening a vehicle lock having a locking mechanism, including the following steps: transferring a blocking element of a blocking device by means of an actuator from a blocking position into a release position, wherein the blocking element blocks the actuation of the locking mechanism in the blocking position and releases the actuation of the locking mechanism in the release position; manually actuating an actuation element arranged at the lock; and transferring the actuation element from a passive state to an active state, wherein a latch of the locking mechanism is transferred from a latched position into an unlatched position by transferring the actuation element from the passive state to the active state, wherein the latch prevents a removal of a counter-piece from the lock in the latched position and allows a removal of the counter-piece from the lock in the unlatched position.

A method for operating a lockset generally includes transmitting an unlock command to an electronic actuator in response to receiving an unlock signal. In response to receiving the unlock command, the electronic actuator performs a first operation, including moving a holdback from a release position to a hold position. In response to actuation of a manual actuator, a latchbolt is moved from an extended position to a retracted position. The holdback in the hold position retains the latchbolt in the retracted position.

A latch dogging assembly comprises an electromagnet and an actuator mounted on a bracket. A guide slide is pivotally mounted on the bracket with a lead block coupled to the guide slide. A guide pin rides along an inner surface of the bracket causing the guide slide to pivot. A pawl is slidably engaged with the guide slide. A guide link includes a post. An armature is mounted to the panic bar and the post engages the pawl. When the actuator is energized to move the lead block, the pawl engages the post to pivot the armature and thereby cause the panic bar to move from the extended position to the depressed position. When the electromagnet is energized the armature is magnetically held preventing reverse pivoting of the guide link. A method for fully retracting a door latch is also provided.

A door lock device is provided and includes: a housing, an acting assembly arranged in the housing and having a lock tongue, an operating assembly arranged in the housing and interlocked with an outdoor handle, and a regulating assembly arranged in the housing for a user to regulate the operating assembly into an interlocking state or an idle state. As such, in the interlocking state, the outdoor handle drives the acting assembly through the operating assembly to cause the lock tongue to extend or retract relative to the housing, and in the idle state, the operating assembly cannot drive the acting assembly and the outdoor handle cannot be interlocked with the lock tongue.
