摘要:
An elevator (11) is provided with a car (13), an inner door (15) mounted to the car (13) and outer doors (17) mounted to floor openings (19) which defines floor zones (21), wherein the inner door (15) registers with the outer doors (17) when the car is disposed within one of the floor zones (21). The elevator includes a door restrictor (42) having an electrical solenoid (53) mounted to the car so that the inner door (15) cannot be opened more than four inches when the elevator is between floor zones (21). The electric solenoid (53) has a plunger (55) which is normally in an extended position to block the inner door (15) from opening. Power will only be applied to the electric solenoid (53) to lift the plunger (55) from the extended position to a retracted position to allow the inner door (15) to be fully opened when both the car (13) is disposed within a floor zone (21) and the inner doors (15) are being opened by the main elevator controls (39). A floor zone sensor (45, 47) is mounted to the car (13) for detecting when the elevator is disposed within one of the floor zones (21). A door sensor (49, 51) is also mounted to the car (13) for detecting when the inner door (15) is being opened by the main elevator controls (39). A controller (43) operates the electric solenoid (53) to lift the plunger (55) from the extended position in response to receiving both a door data signal from the door sensor (49, 51) and a floor zone data signal from the floor zone sensor (45, 47).
摘要:
Die Ver- und Entriegelungsvorrichtung (1) für Türen (11, 13) ist vorgesehen für eine Aufzugsanlage, die eine Aufzugskabine (2) mit mindestens einer Kabinentür (11) und mindestens eine Schachttür (13) umfasst. Mittels einer an der Aufzugskabine (2) angeordneten Betätigungseinrichtung (5, 6, 7, 8, 18) ist ein bewegbares Teil (8) bewegbar, um ein Mittel (9, 12) zur Ver- und Entriegelung der Schachttüren (13) und ein Mittel (10) zur Ver- und Entriegelung der Kabinentür (11) zu betätigen. Bei einer Bewegung des bewegbaren Teils (8) ist das Mittel (10) zur Ver- und Entriegelung der Kabinentür zwischen einer Verriegelungs- und einer Entriegelungsstellung bewegbar. Ein stationäres Mittel (4) ist derart angeordnet, dass es einen Bewegungsspielraum des bewegbaren Teils (8) derart limitiert, dass das Mittel (10) zur Ver- und Entriegelung der Kabinentür (1) nicht mittels einer Bewegung des bewegbaren Teils (8) in die Entriegelungsstellung bringbar ist, wenn sich die Aufzugskabine (2) ausserhalb eines vorgegebenen Bereiches an der Schachttür befindet.

摘要:
An electromagnetic door lock assembly (30) includes a first portion (32) supported relative to hoistway doors (22) and a second portion (34) supported for movement with an elevator car (24). The first and second portions cooperate so that electromagnetic interaction between them unlocks a set of hoistway doors (22) for access to the car (24), for example. In disclosed embodiments, a first portion (32) of the actuator has at least one stationary electromagnetic portion (36A, 36B) and at least one moveable portion (38). The second portion (34) that moves with the car (24) includes at least one stationary electromagnetic portion (44). Magnetic interaction between the first and second portions (32, 34) causes selected movement of the moveable portion (38) for selectively locking or unlocking the doors (22).

The invention concerns a fail safe lock (1), in particular for an elevating device landing door (2), comprising within a housing (16): a bolt (10) provided with a core (200) capable of co-operating with a striker (201) integral with the door leaf; a mechanism for moving said bolt (10) towards an extreme locking position wherein it is engaged in a locking part (20) integral with the door (2), said moving mechanism being controlled by the core (200); an operating arm for controlling the withdrawal of the bolt (10) towards an extreme withdrawn position; and a mechanism for limiting the torque exerted on a connecting rod associated with said operating arm. The lock (1) further comprises a mechanism (7, 14) for adjusting the bolt (10) engaging position.
摘要:
An elevator interlocking mechanism, having interlocking of the elevator (1) cage door and interlocking of each landing door (48), comprises operating means for releasing the interlockings when the elevator cage (1) is at rest at a landing. In this case the elevator cage interlocking comprises an elevator door locking rod (8), which in a locking position engages a lock pin (11), which prevents the elevator cage door from being opened, each landing interlocking including a corresponding landing door locking rod (32), which in a locking position engages a locking pin (38), which prevents the landing door from being opened. Thereby, the locking rods (8, 32) are jointly operated by a single operating means (2, 4) in such a manner that the operating means at a proper landing position displaces the elevator locking rod (8) from its locking position, this locking rod (8) in turn displacing the landing door locking rod (32) from its locking position by means of a cam (30) rigidly connected to said latter locking rod (32).
