A door-locking device (1) including an actuator (20); a locking pin (11) controllable by the actuator (20) and adapted to cooperate with a movable latching slider (7) to lock a door of an electrical household appliance, the locking pin (11) being movable between a rest position, wherein the locking pin allows the latching slider (7) to move, and a lock position, wherein the locking pin prevents the latching slider (7) from moving; a detection switch (45) able to switch between an open position and a closed position following a movement of the latching slider (7), the detection switch (45) including a fixed contact element (45e) and a movable contact element (45c) resiliently stressed in closure towards the fixed contact element (45e), and a movable control member (46) interacting with the movable contact (45c). The control member (46) is also movable by a movement of the locking pin (11).

An electro-mechanical unlocking device that includes a locking state, a holding state and an unlocking state. The unlocking device includes an arming solenoid and a holding solenoid. In the locking state the arming solenoid moves an arming assembly, which moves a crank and which moves a holding armature from a second position to a first position. In the holding state the holding solenoid is energized and the arming solenoid is de-energizing, which allows the arming armature to moves from the first position to the second position. In the unlocking state the holding solenoid is de-energized, which allows the holding armature and the arming link to move from the first position to the second position. In the locking and holding states a sear blocks the path of the striker and in the unlocking state the sear does not block the path of the striker.

A dual-contact electro-permanent magnet (EPM) assembly of an information handling system may comprise a plurality of high-coercivity magnets situated on opposite ends of a low-coercivity magnet, a first EPM magnetic contact disposed between a first of the plurality of high-coercivity magnets and the low-coercivity magnet, and a second EPM magnetic contact disposed between a second of the plurality of high-coercivity magnets and the low-coercivity magnet. The low-coercivity magnet polarity may correlate to a direction of current pulse applied to an electrically conductive wire coiled around the low-coercivity magnet, and dependent upon the low-coercivity magnet polarity, the first EPM magnetic contact is capable of operating in an attractive magnetic state to attract a ferromagnetic contact of a peripheral device while the second EPM magnetic contact is magnetically neutral with respect to the ferromagnetic contact.

A buckle device comprises a main body unit, a latch unit and a fastening unit. The main body unit includes a housing surrounding and defining an accommodating space, two first apertures provided in the housing, two slider blocks arranged in the accommodating space, and two first elastic bodies abutting against the slider blocks. The latch unit includes a tongue element and two tongue openings provided on the tongue element. The fastening unit includes two bolt bodies passing through the first apertures, and two second elastic bodies abutting against the bolt bodies. When the tongue element is separated from the two slider blocks, the two slider blocks are pushed by the two first elastic bodies, and the two bolt bodies is pushed against by the two slider blocks. When the tongue element is in contact with the two slider blocks, the two slider blocks are pushed by the tongue element, and the two bolt bodies are pushed into the two tongue openings by the two second elastic bodies, so that the tongue element can be securely fastened. Accordingly, the external pulling force of the tongue element can be increased, and the structure of the buckle device can be effectively improved.

The present disclosure provides a solenoid assembly that includes a static housing, a plunger disposed within the housing and translatable along an actuation axis in response to a magnetic actuation force, an intermediate element disposed within the housing and surrounding at least a portion of the plunger that is also translatable along the actuation axis in response to a magnetic actuation force. A coil arrangement is disposed within the housing and provides a first and second magnetic actuation force in response to electrical excitation thereof. The coil arrangement is arranged such that the first magnetic actuation force is configured to translate the intermediate element and the plunger together with respect to the static housing, and the second magnetic actuation force is configured to translate the plunger with respect to the intermediate element. This can improve the stroke length of the solenoid assembly.

A door lock facility includes a tongue pivotally attached to a housing with a pivot pin, an elbow is rotatably attached to the housing and includes a limb engageable with and detachable from an inner end portion of the tongue, an anchor is rotatably attached to the housing and includes one end portion located close to the tongue for anchoring a free end portion of the limb between the anchor and the tongue, a follower is slidably engaged in an actuator and movable into and out of the actuator for moving the anchor toward and away from the limb, and the actuator includes a rod slidably engaged in the actuator and moveable out of the actuator in order to rotate the elbow relative to the housing and to move the limb of the elbow from the tongue.

The control member (46) is also movable by a movement of the locking pin (11).

A latch and lock assembly includes a lever pivotable between a latched and unlatched position. A first actuator selectively moves a locking tab between a locked and unlocked position. In the locked position, the locking tab blocks pivotable movement of the lever from the latched position to the unlatched position. In the unlocked position, the locking tab allows pivotable movement of the lever from the latched position to the unlatched position. A second actuator selectively rotates a door opening tab between a first and second position when the locking tab is in the unlocked position is included. When the door opening tab is in the first position the lever is in a latched position, and when the door opening tab is rotated from the first position to the second position, the door opening tab abuts the lever and urges the lever from the latched position to the unlatched position.
