Embodiment Construction

[0077] figure 1 Shown is a sensor 1 with a socket 2 (shaft) and a contact bridge 3 , wherein the bridge has a reflective strip 9 which reflects the light emitted by the transmitter of the socket 2 in the direction of the receiver of the socket 2 .

[0078] figure 2 More precisely, the corresponding socket 2 is shown in front, side and top views with a transmitter 4 and a receiver 5 between which a separating web 6 is arranged. Reference numeral 7 denotes an assembly device and an assembly aid. The contact bridge 2 has further electrical connections via which the sensor 1 can be connected to the rest of the sensor arrangement and to the safety circuit.

[0079] image 3 The contact bridges are shown in different views, precisely in a front view, a side view and the drawing. The contact bridge also includes a corresponding assembly aid 8 . Grooves are incorporated as transmission elements 9 in the contact bridge 3 , said grooves each having a reflective surface. In summar...

Abstract

Safety apparatus for elevator apparatuses which can move a cab via a drive, wherein the drive can he monitored via a monitoring unit for monitoring the drive, comprising: a first safety circuit, which has a closed conduction state and an open conduction state, with an interruption apparatus for interrupting the drive depending on the conduction state of the first safety circuit, a safety device, which comprises at least two sensors, which can be switched between at least two switching states depending on a state to be detected by the sensors. To provide improved maintenance, a switching unit is provided, which can be switched between at least two switching states by connection to the safety device and is designed to effect the closed and / or open conduction state of the first safety circuit, wherein the switching unit comprises a transmission device for transmitting data and / or monitoring signals to the monitoring unit.

Description

technical field [0001] The invention relates to a safety device for an elevator installation according to the preamble of claim 1 and to an elevator installation according to the preamble of claim 14 . Background technique [0002] Conventional safety devices for elevators using electrical or electromechanical switches to determine the locked or closed state of the elevator doors are known from the prior art. In this case, the elevator car should only be allowed to travel when all doors are locked. For example, if the elevator doors are blocked and cannot be closed, the car should also not be able to continue its journey. In order to achieve this, for example, in conventional elevator installations, a corresponding electromechanical switch opens a contactor located at the door, which is connected into the drive circuit, and thus by interrupting the power supply to the drive motor through the contactor. The drive is interrupted directly. [0003] The object of the present ...
