Abstract (en)

[origin: DE19735360C1] The invention relates to a tripping device for a moving stairway contact mat, comprising a tread plate (12) which interacts with said tripping device (20) and which is mounted on a base frame (G). The tripping device (20) has an evaluation and switch device (S) for controlling the operation of the moving stairway. A bending beam (22, 26, 122) is also provided. Said bending beam supports at least one strain gauge (DMS), said strain gauge being connected to the evaluation and switch device (S), and can be fixed on the tread plate (12) or on the base frame (G). An actuating pin (24, 24', 124) is in contact with the bending beam (22, 26, 122) and can be supported on the tread plate (12) or the base frame (G). When the tread plate (12) is subjected to a predetermined load, said actuating pin (24, 24', 124) causes a bend strain to be exerted on the bending beam (22, 26, 122). Said bend strain is detected by the strain gauge (DMS).
