Problems solved by technology

[0004] The problem with such a switching device is that the distance of the magnet from the triggering latch position of its associated proximity sensor can likewise be influenced by, for example, an incorrect position of a damaged door leaf.
This means that the deviation of the magnet from its set trajectory around the latching position of the door leaf means that the latching position itself is shifted, which in turn causes the elevator doors to fail and thus the elevator installation to stop

Embodiment Construction

[0031] figure 1 An elevator door 2 arranged in an elevator installation is shown. The elevator door 2 can be designed as a car door or as a shaft door arranged on the floor 12 of the floor. The elevator door 2 comprises a door frame 8 and a first door leaf 6.1. In addition, the elevator door can have a second door leaf 6.2 and / or a latching device 10 for latching the door leaf 6.1.

[0032] The latching device 10 has a latch 16 and a mechanical stop 14 . The latch 16 can, for example, be coupled to the first door leaf 6.1, and the stop 14 can be fastened to the second door leaf 6.2 or to the door frame 8. When the latch 16 engages the mechanical stop 14 , the opening movement of the first door leaf and possibly also the second door leaf 6 . 1 , 6 . 2 is prevented. In order to monitor the latching state, the switching device 4 can be arranged on the latching device 10 .

[0033] exist Figure 2A , Figure 2B In , a switching device 4 for an elevator door 2 according to t...

Abstract

A switch device (4) for providing a door contact signal (S) for an elevator door (2) is shown, the switch device (4) comprising: a magnet (20), a plurality of proximity sensors (22a, 22b; 22c, 22d), a detection space (DR), wherein the proximity sensors (22a, 22b; 22c, 22d) are adjacently arranged on the detection space (DR); the magnet (20) can move in the detection space (DR), wherein , for at least one position of the magnet (20) in the detection space (DR), a sensor signal (24a, 24b; 24c, 24d) can be generated by means of each proximity sensor (22a, 22b; 22c, 22d), the sensor signal (24a , 24b; 24c, 24d) are related to the distance between the magnet (20) and the proximity sensor (22a, 22b; 22c, 22d), and show a method for providing the door contact signal (S) by means of the switching device (4). Methods.

Description

technical field [0001] The invention relates to a switching device for providing a door contact signal for an elevator door. The invention also relates to a method for providing such a door contact signal by means of such a switching device. Background technique [0002] The elevator installation has an elevator car and elevator doors, in particular car doors and shaft doors. The shaft door is provided, for example, with at least one door contact switch by means of which it is monitored whether the shaft door is unlocked. Such door contact switches, which are arranged on the individual shaft doors, are connected into the safety circuit. When one of the shaft doors is unlocked, the safety circuit is interrupted. The elevator car can then only travel when all shaft doors of the elevator installation are latched. Furthermore, other states or positions of such elevator doors, in particular the open state or the locked state, can be monitored by means of door contact switches...
