Furthermore, the door apparatus has a locking element and a coupling element.

A window regulator includes a carrier plate to support a window glass of a vehicle, a guide rail along an ascending/descending direction of the window glass to slidably support the carrier plate, a wire to pull the carrier plate, a driving portion arranged at one end of the guide rail in the ascending/descending direction to drive the wire, and a turnaround portion arranged at an other end of the guide rail in the ascending/descending direction to turn the wire around. The wire arranged between the turnaround portion and the carrier plate is positioned shifted from the guide rail. The wire arranged between the driving portion and the turnaround portion is positioned on the guide rail to push and contact the guide rail.

A window regulator includes a carrier plate, a guide rail, an ascending-side wire and a descending-side wire, a driving portion, and a turnaround portion. The driving portion includes a rotating drum, a reducer, and a driving motor including a yoke portion that is arranged to be adjacent to one side of the reducer in an orthogonal direction orthogonal to the ascending/descending direction. The guide rail is arranged so as to in the orthogonal direction overlap only the ascending-side wire fed out from a first wire feeding-out position at the one side of the rotating drum in the orthogonal direction toward the turnaround portion between the ascending-side wire and the descending-side wire fed out from a second wire feeding-out position at an other side of the rotating drum in the orthogonal direction toward the carrier plate.

The invention relates to a door arrangement (1) for a first enclosed space enabling a sealed connection between the first enclosed space and a second enclosed space, comprising a flange (2) defining an opening into the first enclosed space, a door (4) hingedly mounted on the flange (2), means for securing the flange of the second space pressed against the flange of the first space, the means comprising locking catches (8) which are movable between an unlocked position in which they are recessed inside the flange (2) and a locked position in which they project radially from the flange (2) to the opening, thereby locking the flange of the second space without rotating the flange (2) by engaging each catch in a notch provided on the outer peripheral edge of the flange of the second space.

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 door drive for arrangement on or in connection with a door system, wherein at least one leaf element of the door system is movable, including a motor unit with a housing, in which a stator is stationarily received, and wherein a rotor is arranged so as to be rotationally-movable in the housing and includes an output shaft, wherein the output shaft can be brought into operative connection in a driving manner with the leaf element. The motor unit has the basic shape of a cuboid, which is formed at least by two housing halves connected to each other.

The present invention relates to a door operator system (1) for opening and closing an opening (2), comprising a drive unit (10), a door frame (3) and a door (8), wherein the drive unit (10) is mounted to the door (8) and adapted to move the door (8) between an open (O) and closed position (C), the door frame (3) comprise at least a first frame section (4) adapted to be mounted at a first side (5) of the opening (2), a second frame section (6) adapted to be mounted at a second side (7) of the opening (2), a first track unit (31) moveably connected to the first frame section (4), and a second track unit (32) moveably connected to the second frame section (6), the door (8) is at a first side moveably connected to the first track unit (31) and at a second side moveably connected to the second track unit (32), wherein the door frame (3) is adapted to move the door (8) between the closed position (C) and an intermediate position (I) and to guide the door (8) between the intermediate position (I) and the open position (O).

A cinching system includes: a profile configured to determine a first time series of target values for cinching a closure closed; an adjustment module configured to determine an adjustment value based on at least one operating parameter; an adjusting module configured to generate a second time series of target values for cinching of the closure by adjusting at least one of the target values of the first time series based on the adjustment value; and a power control module configured to: apply power to a cinching motor when the closure is partially closed, where the cinching motor is configured to cinch and fully close the closure; and based on a comparison of a measured value of the cinching motor and one of the target values of the second time series, selectively one of: decrease power applied to the cinching motor; and disconnect the cinching motor from power.

An example retention assembly has a motor assembly and a self-locking worm drive coupled thereto. A cam is fixed to a worm gear of the worm drive. The retention assembly has an actuation shaft including a follower. The actuation shaft is displaceable over a displacement range via rotation of the cam. The retention assembly has a securement member with a securement member follower, the securement member coupled to a portion of the actuator shaft. The retention assembly has a housing cam included as part of the retention assembly housing and against which the securement member follower is biased. The securement member are in an open state when the actuation shaft is in a first position. The securement member swings outward to a retaining position as the actuation shaft is moved to a second position.

A refrigerator comprising a door rotatable about a hinge shaft. A door opening and closing apparatus comprises a drive motor, a first gear configured to receive power from the drive motor, a second gear, spaced apart from the first gear, configured to transmit a rotational force to the hinge shaft, a clutch gear configured to be rotatable around a rotation axis of the first gear, and configured to transmit power of the first gear to the second gear based on a position of the clutch gear around the rotation axis of the first gear, and a position detection sensor configured to detect the position of the clutch gear so that while the clutch gear is at the position, the clutch gear transmits the power received from the first gear to the second gear which transmits the rotational force to the hinge shaft to open and close the door.
