Abstract: An elevator door interlock assembly and an elevator system. The elevator door interlock assembly includes: a first base plate on which a common rotating shaft is arranged; a first hanging wheel, which is pivotally connected to the first base plate through the common rotating shaft and guides the first base plate to reciprocate in an opening and closing direction of an elevator door; and a first lock arm, a middle part of which is pivotally connected to the first base plate through the common rotating shaft, so as to rotate between a locked position and a released position when the elevator door is closed.

Abstract: A door interlock of the present invention includes an engaged part and an engaging part configured to lock a door in a door closed state. The engaging part includes: a locking member; a mounting member mounted to the locking member; a sim member inserted into a slit; a first fixing member; and a second fixing member. The first fixing member is configured to be inserted into a first lock through hole, a first sim through hole, and a mount through hole, thereby fixing the mounting member and the sim member to the locking member. The second fixing member is configured to be inserted into a second lock through hole and a second sim through hole, thereby fixing the sim member to the locking member.

Abstract: The present invention concerns a wind power installation working gallery comprising a working platform and a railing arranged on the working platform, wherein the railing can be closed off by means of a closure element and the closure element is arranged in a transfer region to a lift. The invention concerns in particular a wind power installation having a locking device with a locking mechanism for receiving a first locking element and a second locking element, wherein the first locking element is connected to the lift and the second locking element is connected to the closure element, and the locking mechanism is adapted to release one of the two locking elements by means of the locking of the respective other locking element relative to the locking device. The invention further concerns a locking device, a lift and a wind power installation.

Abstract: A door coupler provided with coupling elements actuated by means of a linkage so as to engage a counter element provided on the landing door and a locking hook that has a closed position and a released position. The release of the locking hook from the closed position to the released position is allowed when the coupling element meets the counter element. The locking hook and the coupling elements are disposed at a distance from each other.

Abstract: A modular lock (10) for elevator doors, in particular for locking and unlocking the floor doors of elevators and hoists, comprises a first fixed plate (12) and a second plate (14) articulated on the same, cooperating with the blades of the car activator and provided with means (52, 62) for striking a contact (48, 56).

Abstract: An improved elevator door system for reducing vibration and noise in opening/closing a car door and a hatch door and allowing fast operation by releasing a landing door lock device before the car door moves. The elevator door system includes a hatch door; a car door; a motor for providing rotating force to open and close the hatch door and the car door; power transmitting means; a rack for possibly moving horizontally by the power transmitting means; a pinion engaged with the rack for rotating by horizontal movement of the rack; clutch connected to the pinion for transmitting or cutting off power toward the hatch door; and door lock engaged with the clutch, the door lock positioned in a lock release state in which the hatch door is movable when the clutch transmits power, while positioned in a lock state for fixing position of the hatch door when the clutch cuts off power.
