Abstract: An elevator door moving arrangement includes a door mover (40) and an interlock device (42) supported near a lower edge (44) of cabin doors (26). The strategic position of the door mover (40) and the interlock device (42) minimizes the distance between the sill member (34, 78) and the operative components for moving the doors. In one example, the entire door mover assembly and the interlock are located beneath a sill member (34), which is beneath the bottom edge of the doors (26).

Abstract: A door locking system for retrofit installation on an automatic sliding two-panel door of an elevator car prohibits opening and closing of the door from the interior of the car when between two floors. The door locking system includes a hook retainer mounted on one side of the door opening. A locking pawl is mounted to a panel of the door on the opposite side of the opening for selectably engaging the hook retainer. A cable is coupled to a drive mechanism and to the locking pawl for disengaging the locking pawl from the hook retainer when at a floor stop. A flexible cable housing slidably retains the cable and defines a path length between the drive mechanism and the locking pawl. A path length adjuster mechanism is connected between two sections of the cable housing for manually adjusting the path length. A hold-down is mounted to the door to retain the cable housing in close proximity to the door while permitting movement parallel with the door in response to adjustment of the path length.

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.

Abstract: The landing door of an elevator is opened by the opening movement of the car door and closed by the closing movement of the car door by using a door coupler (20) attached to the car door. The door coupler has coupling elements (52,53) designed to engage a counterpart (6) attached to the landing door. The door coupler (20) is moved in the direction of the car door movement to align it with the counter element (6). After the door coupler (20) has been aligned, its motion relative to the car door is prevented by a blocking device (28).

Abstract: A door coupler (4) comprising gripping elements (14,15) moved by a linkage (2) and designed to grip a counterpart (17,18) on the landing door, and a lock catch (10) which has a closed position and an open position. The releasing movement of the lock catch (10) from the closed position into the open position is allowed when a gripping element is pressed against a counterpart.

Abstract: An elevator interlocking mechanism interlocks the elevator cage door and each landing door, and includes a release mechanism for release of the interlocks when the elevator cage is at rest at a landing. The elevator cage interlock comprises an elevator door locking rod which in a locking position engages a lock pin to prevent the elevator cage door from being opened. Each landing interlock includes a corresponding landing door locking rod which in a locking position engages a locking pin, which prevents the landing door from being opened. The locking rods are jointly operated by a single operating device so that the operating device--at a proper landing position--displaces the elevator locking rod from its locking position, and in turn the locking rod displaces a landing door locking rod from its position using a cam.
