Embodiment Construction

[0071] figure 1 combine figure 2 An overall schematic view of the elevator installation 1 is shown. The elevator installation 1 is installed in a building or in an elevator shaft 6 of a building and is used for transporting people or goods within the building. The elevator installation 1 comprises an elevator car 2 which can be moved up and down along guide rails 10 . The elevator car 2 is accessible from the building through a door. The drive 5 is used to drive and hold the elevator car 2 . The drive unit 5 is arranged in the upper region of the elevator shaft 6 and the car 2 is connected to the drive unit 5 via support means 4 , such as support ropes or support belts. The carrier device 4 is guided further towards the counterweight 3 via the drive device 5 . The counterweight balances the weight components of the elevator car 2 so that the drive 5 actually only has to compensate for imbalances between the car 2 and the counterweight 3 . The drive 5 is arranged, for ex...

Abstract

The invention relates to a device (14) and a method for activating and resetting a safety gear in an elevator installation (1) as well as a correspondingly configured elevator installation. The device (14) comprises a pressure accumulator (24), preferably a pressure spring, capable of moving at least two gripping elements (12) of the safety gear (11) substantially synchronously to the gripping position when required, the device also A remotely controllable reset device (30) is included, which can preload the pressure accumulator again into the ready position.

Description

technical field [0001] The invention relates to a device and a method for activating and resetting a safety gear in an elevator installation and to a correspondingly retrofitted elevator installation. Background technique [0002] Elevator installations are built into buildings. It mainly consists of an elevator car connected to a counterweight or to a second elevator car by carrying ropes or carrying belts. The car travels along substantially vertical guide rails by means of a drive acting optionally on the carrier, directly on the car or on the counterweight. Elevator installations are used to transport people and goods within a building on one or more floors. [0003] Elevator installations include devices for securing the elevator car in the event of a drive or carrier failure or for preventing unintentional slipping or falling when it stops at a floor. For this purpose, fall arresters are generally used, which can brake the elevator car on the guide rails if necessar...
