A brake triggering device for an elevator car actuates a pair of brake devices (13) disposed at opposite sides at a car structure (1) from a limiter cable (11) and an entraining lever (10) utilizing a trigger element (2). A small upward movement of the entraining lever (10) releases, by way of a Bowden pull (9) and a trigger mechanism (4), the trigger element (2) which is moved by a spring force to actuate the two brake devices (13) simultaneously. The trigger element (2) is constructed as a torsion spring and has a very short reaction time. |
