Arrangement for switching off motor drive, e.g. for electrically driven shutters, has flat spring held centrally in metal tube by bearing beam in spring plate with ends in anchoring plate

摘要

The arrangement has at least one flat spring (12) held centrally in a metal tube forming a housing by a bearing beam (13) in a spring plate (19) with its ends mounted in an anchoring plate (23). The spring plate is rotatably mounted on the anchoring plate on a slide bearing (22). The spring plate has at least two unrolling surfaces in contact with the flat spring near the beam and that depart from it in an arc with an unrolling radius.
