Abstract: A safety system for restraining movement of an elevator car employing a bi-directional safety and an associated car mounted governor with a linkage, between the governor and the elevator car door, including a brake cable and clutch, wherein the governor would operate normally when the elevator car door is closed to set the safety in the event overspeed in either direction. When the door is open more than two (2) inches, for example, the governor would set the safety in the event the car moved more than a predetermined distance.

Abstract: A safety device includes a trigger mechanism for triggering a braking wedges attached to first and second double levers to stop an elevator car.

In order to enable a more rapid filling of the building, a conversion unit responds to the destination call travel orders already allocated to and/or demanded of the multiple car having the deck which is to be allocated to the passenger to minimize the number of stops of the car. An indicating device indicates to the passenger the allocated car deck and/or the main stopping floor thereof.

Abstract: Equipment for temporarily coupling an elevator car door leaf with a shaft door leaf and for actuating a car door lock includes a coupling mechanism arranged at the car door leaf with two entraining runners mounted on two pivotable adjusting elements. The spacing between the entraining runners can be adjusted by pivoting of the adjusting elements between an uncoupling setting and a coupling setting, wherein the entraining runners in the coupling setting co-operate with at least one coupling element mounted at the shaft door leaf. One of the entraining runners is coupled by way of a respective articulation member with one arm of each of the two adjusting elements, wherein a contact force arising between the entraining runner and the corresponding coupling element in the coupling setting causes the entraining runner to execute an additional movement which is guided by the articulation members to unlock the car door lock.

Abstract: An elevator door restrictor system for preventing an elevator door from being opened unless the elevator car is near a floor landing, utilizing battery backed electronics for sensing the presence of a building landing such that the system will continue to maintain the mechanism in the correct state, either locked or unlocked, even if the elevator car continues to move. Wherein even if the battery backup were to become completely discharged, the mechanism will remain in the last state, either locked or unlocked and prevent the elevator car door from being opened until an authorized person takes the appropriate step to move the car or open the car door.

Abstract: An elevator door drive device, which opens and closes at least one car door leaf and a corresponding shaft door leaf, includes a coupling mechanism mounted at the car door leaf for transmitting the car door leaf movement to the shaft door leaf with two parallel entraining runners mounted on pivotable adjusting elements. The spacing between the runners is adjustable and a drive unit transmits closing and opening movements to the car door leaf by way of a drive apparatus that leads the entraining runners to a coupling element at the shaft door leaf before the start of the opening movement and moves them away from the coupling element after the end of the closing movement. The pivotable adjusting elements, during opening or closing the door leaf are blocked by means of a catch acting in both pivot directions.
