A system for ensuring that a door automatically closes and latches while simultaneously ensuring that it does so in a manner which either eliminates or significantly minimizes the amount of noise such closure causes while making sure that the door does in fact fully close and latch. A door mounted portion includes a piston attached to a pivotable arm having a wheel on the end of the arm configured to engage with a doorframe mounted portion to slow the travel of the door into the doorframe while pulling the door into the doorframe to ensure secure closure of the door. A doorframe mounted striker plate portion is configured with at least one spring-loaded striker damper or flap against which a door latch and/or automatically deploying deadbolt lock engages, to slow the engagement of the door latch or deadbolt with striker region in the frame to minimize noise.

Embodiments of the present invention provide a controller, a system, a method and a vehicle, to receive one or more user inputs from one or more user input units; receive one or more vehicle condition inputs from one or more vehicle condition sensor units; determine if an open position of a aperture member of a vehicle is likely to cause buffeting; select an optimisation strategy from a plurality of optimisation strategies in dependence on the one or more user inputs and/or the one or more vehicle condition inputs, wherein each of the plurality of optimisation strategy comprises different instructions to determine one or more positions for at least one aperture member; and generate an output for the one or more aperture member positioning units to move at least one aperture member based on the selected optimisation strategy.

The present invention relates to a device capable of guiding a stable rotational actuation between a first support bracket fixedly connected to a supporting frame side of a door frame and a second support bracket fixedly connected to the door side in a gear hinge unit constituting a rotating door, specifically, in a door hinge in which a gear hinge unit is provided between the first support bracket fixedly connected to the support frame side of the door frame and the second support bracket fixedly connected to the door side, by minimizing the compressive stress generated in the lower gear hinge unit under a neutral axis of the door and the tensile stress generated in the upper gear hinge unit above the neutral axis of the door by the rotational moment applied to the gear hinge unit due to the load of the door, it is possible not only to secure and maintain the correct opening/closing performance of the door, but also to minimize damage to parts caused by friction or friction noise in the door hinge.

A door striker has an improved cross-sectional shape so that a latch can be maintained in close contact with the striker without back-and-forth clearance. In contrast, with conventional strikers, a door may make noise by being shaken due to application of external forces including changes in indoor and outdoor air pressure. Door strikers described herein include a latch assembly on a side surface of a door, which is connected to and operated by a handle member. A striker, to which a latch of the latch assembly is fitted, is installed on a door frame. The striker has a front latching protrusion for latching a front surface of the latch and a rear latching protrusion for latching a rear surface of the latch. The front latching protrusion has a right-angled surface of a front end thereof and an inclined surface the inside thereof.

Systems and methods for providing a drop seal assembly which is concealed within an opening in the bottom of a sliding door panel of a top-hanging sliding door. The drop seal assembly may include bottom guide which defines a downward facing elongated slot or track which receives a sill guide therein. The drop seal assembly also includes a drop down acoustic seal which automatically drops down to contact the floor surface below the door panel when the door panel is moved from an open position into a closed position. The distance that the seal drops down upon closing of the door panel may be selectively adjustable to accommodate variances in the air gap between the door bottom and the floor surface due to particular installation conditions. A concealed magnetic bottom seal activator may be used to provide self-adjusting activation of the door bottom seal assembly using two opposing magnets.

Method and apparatus are disclosed for determining and mitigating wind throb caused by an open vehicle window. An example vehicle includes a plurality of windows corresponding to a plurality of seats having respective occupancy sensors, a microphone, and a processor. The processor is configured to determine that a first window is open, determine, based on microphone data, that a sound pressure level is above a threshold level, and responsively open a second window selected based on occupancy data determined by the occupancy sensors.

The disclosure relates to a cooking appliance capable of reducing noise generated when a door is closed using a buffer member that is easily fixed to a hinge unit. The cooking appliance includes a main body, a cooking chamber provided to have a front surface opened inside the main body, a door to open and close the cooking chamber, a hinge unit coupled to the main body to rotatably support the door, and a buffer member fixed to the door to buffer an impact generated when the door is closed by contacting the hinge unit when the door is closed.

A device for moving a furniture part held on a furniture body of an item of furniture having a guide with at least one pivot arm for pivoting the furniture part from a closed position into an open position relative to the furniture body and back with a base unit with an anchor plate. The device includes a positioning mechanism with a positioning portion formed in an intermediate region between the at least one pivot arm and the base unit. During a pivoting movement of the pivot arm, the positioning portion contacts an abutment surface on the pivot arm and/or on the base unit. Fine positioning of the pivot arm in an axial direction relative to its pivot axis is configurable by contact of the positioning portion with the abutment surface if the pivot arm has an axial offset with respect to a setpoint bearing position of the pivot arm.

A door hinge assembly is provided. The door hinge assembly includes a first hinge plate, a second hinge plate, one or more bushings, a hinge pin and a hollow sleeve. The first and second hinge plate includes a one or more first and second knuckles aligned axially. At least one of the one or more bushings is positioned in between the first and second knuckle to prevent direct contact of first and second knuckle. The hinge pin is disposed through the first and second knuckles and one or more bushings. The hollow sleeve acts a covering to the hinge pin. The hollow sleeve further prevents contact of the sides of the first knuckle, bushings and second knuckle with the hinge pin. This prevents a direct metal on metal contact and further prevents squeak or other noises occurred during the opening and closing of the door.

A building sliding door system separates a first building region from a second building region and has a frame structure that has a passage region and a wall shell region. A sliding door is displaced in the frame structure between a closed position and an open position, wherein the wall shell region at least partially receives the sliding door in the open position. An electromechanical drive unit and a control device control the displacement of the sliding door. A fire protection unit has a bracket and, movably mounted on the bracket, a fire protection device made of a material having a defined fire resistance. The fire protection device is horizontally displaceable within the wall shell region with respect to the bracket between a retracted position in which the sliding door is in the open position, and an extended position in which the sliding door is in the closed position.
