A compartment assembly includes a swinging door, a fixed structure to which the swinging door is movably coupled, at least one hinge assembly according to the present disclosure.

An apparatus comprises a base plate configured to be coupled to a door, the door configured to be positioned in an open position and a closed position; a closing mechanism coupled to the base plate and configured to be coupled to a hinge of the door and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein in the unprimed state the closing mechanism is decoupled from operation of the door; and in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal.

A latch assembly comprising an elongated flat latch slider slidable along a first axis between a first position and a second position in relation to a main latch, wherein the latch slider is provided with a protruding lug; a lock arrangement comprising; a body moving between a locking position and an unlocking position, wherein in the locking position a portion of the body is preventing movement of the lug along a path in parallel with said first axis, and in the unlocking position the lug can be moved along said first axis; and an electrically powered device connected to the body for moving the body between the locking position and the unlocking position.

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).

The invention relates to a device for releasing and resetting a fire and smoke barrier. In a normal use state, a clutch member is held by an electromagnetic attraction unit, so that a push rod ejecting module cannot be actuated, and a door operator is controlled by a clutch module thereof. Upon power failure, for example upon an accident, the clutch member is released by the electromagnetic attraction unit, and a barrier release member is activated by the push rod ejecting module so as to shut the fire and smoke barrier. Upon power restoration, the clutch member is attracted and held by the electromagnetic attraction unit, and the push rod ejecting module is reset by a push rod resetting module. At the same time, the barrier release member is also reset.

An automatic door opening system including a door having a top portion, a bottom portion, a hinged portion, and an opening portion. The system includes an opener connected to the door adjacent the opening portion and configured to selectively receive electrical current. The system includes a magnet disposed on the opening portion of the door such that the magnet is adjacent the opener when the door is in the closed position. The system includes a microcontroller in electric communication with the electromagnet wherein a memory contains processor-executable instructions to receive a door activation input and, in response to receiving the door activation input, activate the electromagnet to apply a magnetic force against the magnet and push the door between the closed position and the open position. The system may also include a closer configured to selectively return the door to the closed position.

An apparatus comprises a base plate configured to be coupled to a door, the door configured to be positioned in an open position and a closed position; a closing mechanism coupled to the base plate and configured to be coupled to a hinge of the door and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein in the unprimed state the closing mechanism is decoupled from operation of the door; and in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal.

Provided are a seamless charging flap opening/closing device and a vehicle including the same. A charging flap cover is additionally provided with a pop-up function to also function as an opening/closing door for an air channel of an air breather, such that the charging flap cover is integrated with the air breather to be unperceivable from the outside during driving and is only opened during charging to allow a battery to be charged. The single charging flap cover is used in common by a charging flap device and the air breather maintaining independent functions. The exterior quality of a product and the efficiency of use of a package is improved, a vehicle body has a distinctive novel exterior image, and the charging flap cover is easily matched adjacently to a moving part located adjacent thereto.

A portable information handling system rotationally couples housing portions with a variable torque hinge having a first axle that rotates with a first housing portion, a second axle that rotates with a second housing portion and a synchronizing gear assembly that translates rotation between the first and second axles. Variable torque is applied by selectively engaging and disengaging a coupler gear with the synchronizing gear assembly to apply and remove an increased torque that resists housing rotation. In one embodiment, the coupler gear is an idler gear of the synchronizing gear mechanism that selectively applies and removes an increase torque of the second axle to the first axle. The coupler gear slides in response to an actuator, such as an electro-permanent magnet acting on a ferromagnetic material with high and low magnetic attraction states.
