Locking device for roller blinds in the closed state

摘要

Locking device for roller blinds which have been let down, having a locking bar which is deflected resiliently when the roller blind is let down, with the result that it can be pushed back by the roller blind, whereas, when the roller blind is pulled up, the locking bar engages in parts of the same and is wedged at the same time owing to a mounting arrangement. The locking action is released by pulling back the locking bar from within via a rod arrangement. In the event of forced opening and pushing-up of the locking bar by the roller blind, electric contact may further be made in order to actuate an alarm system.
