1. 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 having two lateral guide strips and a connecting strip as a side orthogonal to the guide strips, wherein the guide strips constitute opposing sides of the frame-like slide element, wherein the guide strips extend in the axial direction of movement of the triggering element and contact two opposite sides of the supporting frame to guide the frame-like slide element in the supporting frame, and wherein the connecting strip supports the triggering rod.
