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.
