Abstract: The present invention relates to a triggering mechanism for a gripping device in an elevator system, comprising a supporting frame, a triggering element that can move axially in the supporting frame, which has a triggering rod on the end that extends through an end section of the supporting frame that can be attached to an activation lever for the gripping device, springs that act on the triggering element at least when in a first standby position, and magnetic retaining means, which are designed to retain the triggering element in the standby position against the spring tension when supplied with electricity, wherein the triggering element is designed as a frame-like slide element, which has two guide strips extending in the axial direction of movement for guiding the frame-like slide element in the supporting frame, and a connecting strip at a right angle to and connecting the guide strips, on which the triggering rod is supported.

Abstract: An elevator system having an elevator car in an elevator shaft and having a measuring tape in the elevator shaft for determining the position of the elevator car in the elevator shaft. The measuring tape is arranged vertically in the elevator shaft and has optical coding for length measurement. At least one marking element which has optical marking is arranged on the measuring tape. The marking element is fixedly arranged on the measuring tape. A sensor device which comprises a lighting source and a sensor which form a detection field for detecting the measuring tape is attached to the elevator car. The elevator system comprises an evaluation device for decoding the codings in the detection field and a control device for controlling the elevator system as a function of the coding and/or of the position of the at least one marking element on the measuring tape.
