Problems solved by technology
[0006] The problem of the susceptibility of the safety circuit is not resolved since such a safety circuit is apparently still present unaltered and in addition to the photodetectors monitoring whether the shaft door is closed and locked
In addition, when there is a person or an object in front of a shaft door that is not fully closed, it will reflect the light that should be projected into the elevator lobby and make the monitoring system ineffective, so this will affect the safety function of the photoelectric detector. adversely affect
Furthermore, a strong light source in the elevator lobby when the shaft door is not fully closed can also adversely affect the safety function of the sensor
Another disadvantage is that there must be a contactless sensor on each floor
A correspondingly large number of sensors in a building with a large number of floors entails an increased susceptibility to interference and a considerable effort to regularly check the large number of sensors
In addition, it will pay a high price for purchasing and installing a large number of sensors

Embodiment Construction
[0055] figure 1 An elevator installation with an elevator shaft 2 and an elevator car 3 is schematically shown in FIG. The elevator car is equipped with a car door 4 having two car door leaves 5 which are displaced horizontally during opening and closing by a door drive unit 6 mounted on the elevator car 3 . The elevator shaft 2 comprises three shaft doors 7 each having two shaft door leaves 8 . When the elevator car is on the corresponding floor, the shaft door 7 is opened and closed by the horizontal movement of the shaft door leaf 8, wherein the driving force of the horizontal movement is transmitted from the car door leaf 5 to the shaft door leaf 8 by the door actuator. The shaft door leaf 8 is locked on the fixed part of the shaft door by a shaft door lock (not shown) in the closed state. A transmitter 10.1 is mounted near the shaft wall with the shaft door at the bottom of the shaft. The emitter emits a beam 10.3 in the form of a bundled electromagnetic wave, preferab...

The invention relates to a method for monitoring shaft doors (7) of a lift installation (1) in which the closed setting of the shaft door panels (8) is monitored by at least one contactlessly acting shaft door monitoring sensor (10) emitting electromagnetic waves, wherein at least during specific detection phases a beam (10.3) in the form of focussed electromagnetic waves and extending over several storeys is emitted by an emitter (10.1) of the shaft door monitoring sensor (10) and detected by a receiver (10.2), the beam being influenced, if one of the shaft door panels (8) is not completely closed and / or if one of t he shaft door locks (22) is not disposed in locking setting, in such a manner that it is recognised by the receiver (10.2) of the shaft door monitoring sensor that one of the shaft doors (7) is not completely closed and / or is not locked, wherein this information is signalled by the shaft monitoring sensor (10) to the lift control.
Description
technical field [0001] The invention relates to a method for monitoring the shaft doors of an elevator installation, said elevator installation having an elevator shaft and an elevator car, said elevator car moving vertically along the shaft wall, wherein the shaft wall has a plurality of shaft doors, each shaft The door has at least one shaft door leaf displaceable horizontally, wherein the door leaf of at least one shaft door opposite to the elevator car is opened and closed by the corresponding car door leaf when the elevator car stops at a floor, wherein the elevator installation comprises An elevator control unit which controls the movement of the elevator car and the car door leaf and the corresponding movement of the shaft door leaf accordingly, and in which the pair of The closing of the shaft door leaf is monitored. Background technique [0002] Elevator installations usually have shaft doors which, in the closed state, separate the elevator shaft from the elevator...
