Abstract: A safety switching for elevator systems includes a safety function and a safety switch dedicated to the safety function. The safety switch opens or closes a safety circuit between one connection point and a second connection point as a function of a safety state of the safety function. A test function tests whether or not the safety switch opens and closes the safety circuit as a function of the safety state of the safety function. A detection device is provided for the test function. An auxiliary energy function is provided wherein an auxiliary voltage can be temporarily applied via at least the safety switch and an input part of the detection device for performing the test function. Locally between the connection points the auxiliary energy function introduces an auxiliary energy for generating the auxiliary voltage. The safety switching can be used for converting or retrofitting an existing elevator system.

Abstract: A switching device for an elevator door provides a door contact signal. The switching device includes a magnet, a plurality of proximity sensors, and a detection area, which area is adjoined by the proximity sensors and in which the magnet can be moved. A sensor signal can be generated by each of the proximity sensors in at least one position of the magnet in the detection area, wherein the sensor signals are dependent on the distance from the magnet to the proximity sensors. A method for providing the door contact signal utilizes the switching device.

Abstract: A system and method for determining an elevator car position uses position markers situated in the elevator shaft and each assigned a discrete car position, first and second detection devices on the elevator car detecting first and second position markers respectively, and an evaluation unit that determines first and second discrete car positions based on the detected first and second position markers respectively. A single interpolation device of the position determining system determines first and second interpolated car positions. The evaluation unit determines first and second car positions based on the first and second discrete car positions and the first and second interpolated car positions respectively. The interpolation device generates an interpolation parameter that characterizes a position of the first detection device relative to the first position marker and determines the first and second interpolated car positions on the basis of the interpolation parameter.

Abstract: A locking system that locks and unlocks a door of an elevator car travelling along a track having stopping points and associated stopping point zones includes a lock mechanism having a locking position wherein the door is immobilized in a closed position and an unlocking position wherein the door can be opened, an actuator for bringing the lock mechanism into the locking and unlocking positions, and a control device activating the actuator to bring the lock mechanism into the unlocking position when the car is located in the region of a stopping point zone. A position detecting unit continuously detects the position of the car relative to the track and communicates the position to the control device that continuously detects whether the car is located in the region of a stopping point zone by comparing the communicated car position to stored position limit values of the stopping point zones.

Abstract: An elevator installation includes a first car and a second car, which cars are arranged on a car frame so as to be displaceable symmetrically in opposite directions. The elevator installation has an information carrier that is arranged along a region of travel of the first and second cars or of the car frame, a first sensor unit arranged on the first car, and a second sensor unit arranged on the second car. The first sensor unit and the second sensor unit are configured to read information from the information carrier, which information determines in each case an absolute position for the first car and for the second car.

Abstract: An elevator system vibration stabilizer device retains an information carrier extending through an elevator shaft at at least one point of the information carrier and includes a retaining element and a clamping element according to an assembly method. The clamping element is connected to the information carrier at the at least one point by a clamping force transmission device whereby the information carrier is applied with a clamping force against at least one contact region on the retaining element. The retaining element is stationary in the elevator shaft. A magnet element is an alternative to the clamping force transmission device. The vibration stabilizer device is included in an elevator system shaft information system to provide a method for preventing vibrations of the information carrier.

Abstract: A safety circuit for an elevator system includes a plurality of switch contacts, at least one first switch contact, and a control unit. The at least one first switch contact can be switched electronically and can be bridged using a conductive bridging element, in particular for maintenance or testing purposes. Additionally, the control unit is directly or indirectly connected to the safety circuit. The at least one first switch contact can be switched on the basis of instructions of the control unit in order to change the state of the safety circuit. In the process, the at least one control unit detects the absence of the state change of the safety circuit, in particular when the at least one first switch contact is being bridged by the bridging element

Abstract: A floor position detection device of an elevator installation, and a method for generating a floor signal, includes a sensor unit and an evaluation unit for generating the floor signal with two states. The states are “in the range of the floor” and “outside the range of the floor”. The sensor unit includes a first Hall effect sensor generating a first floor position characteristic value and a second Hall effect sensor generating a second floor position characteristic value. The evaluation unit generates the floor signal on the basis of a comparison between the first and the second floor position characteristic values. The evaluation unit verifies whether the first and/or second floor position characteristic value is higher than a first threshold value and generates the floor signal on the basis of the result of the verification.

Abstract: A safety monitoring device monitoring safety-related states in a passenger conveyor system has first and second double contact relays each controlled by a control voltage to switch first and second normally open contacts and a feedback contact synchronously between an open and closed relay states. First and second controllers each determine properties of the system correlated with safety-related states and in dependence generate the control voltages. The controllers and two double contact relays form first and second safety monitoring switch arrangements for monitoring first and second safety-related states and correspondingly switch first and second switching states within a safety monitoring chain of the system. The first arrangement includes the first contact of the first connected in series with the first contact of the second relay. The second arrangement includes the second contact of the first relay connected in parallel with the second contact of the second relay.
