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 arrangement includes a car, an elevator control having car position current information, a plurality of fixtures, at least one sound generator at one of the car and each of the fixtures, and at least one sound detector at the other of the car and each of the fixtures. A fixture position learning procedure includes: travelling the car to and, preferably, stopping at each of the floors; at each floor stop, generating a sound signal from the sound generator at the car or the fixture at the floor stop, detecting the sound signal using the sound detector, determining a position information for the fixture at the floor stop by assigning information on a current position of the car from the elevator control, and storing the position information for subsequent identification purposes, whereby the identity/position of each of the fixtures is determined in the automatically performed learning procedure.

Abstract: An elevator system includes a first elevator car, a second elevator car, a drive-machine, and a suspension apparatus that passes over a traction sheave of the drive-machine to cause the cars to travel one above the other in a travel space. The suspension apparatus is divided into a first set and a second set. A displacement mechanism fixed in the travel space interacts with the second set between the traction sheave and the second car to vary the distance between the cars. This distance can be adjusted independent of the traction sheave. The displacement mechanism can have a pulley arrangement with a displaceable pulley displaced by a displacement drive to vary a length of a section of the second set between the displacement mechanism and the second car.

An elevator braking device includes a brake element, a force store, which is constructed to press the brake element against the brake surface, and an actuator, which can act on the brake element. A method of operating the braking device includes the actuator pressing, in a first operational setting, the brake element against the force of the force store away from the brake surface or to hold it at a spacing therefrom, and the actuator freeing, in a second operational setting, the brake element and allowing the force store to press the brake element against the brake surface.

Abstract: A lightweight glass plate includes a first glass plate, a second glass plate and an intermediate layer that connects the first and the second plates together. The lightweight glass plate further includes at least one connection element that allows the lightweight glass plate to be connected to an abutting component. The connection element is embedded into the intermediate layer in an edge area of the lightweight glass plate and the intermediate layer extends to surfaces located between the connection element and the glass plates. The lightweight glass plate is preferably used in the preparation of elevator doors and/or car walls. The lightweight glass plates are lightweight and can transfer large forces.

Abstract: An elevator cage is movable along at least two guide rails and the elevator cage is equipped with a braking system. The elevator braking device has a brake housing and a force store. The brake housing is mounted to be displaceable between a first position and a second position. The force store acts on the brake housing and pushes the brake housing in the direction of a second position. In addition, the elevator braking device includes an actuator which can act on the brake housing and keep the brake housing in a first position. The actuator in its first setting can hold the brake housing in the first position against the force of the force store. In a second setting the actuator enables pushing of the brake housing into the second position. A brake element is thereby brought into contact with the brake rail.

Abstract: An elevator car has a car body with movably mounted car door leaves having upper guide rollers and a roof frame which stabilizes the car body. In addition, there is a door drive for moving the car door leaves and a horizontal door guide rail for mounting and guiding the car door leaves. A door drive carrier is arranged on a horizontal surface on an upper face of the roof frame horizontally along an upper front horizontal edge of the car body. The door drive carrier has a vertical surface section which runs parallel to a vertical front side of the roof frame and a horizontal surface section which runs parallel to the horizontal surface of the roof frame. The guide rail is fastened directly to the vertical front side of the roof frame.

Abstract: In an elevator installation an elevator cage is arranged to be movable along guide rails and the elevator cage is equipped with a brake system possibly with two safety brakes. The safety device is activated by way of control devices which can trigger the safety device from critical or non-critical events. The control devices further include a function for automatic resetting of the safety brake when an event, which is evaluated as non-critical, is indicated as a reason for triggering the safety brake. Resetting of the safety brake takes place through execution of pre-defined resetting steps of the elevator cage.
