Device for closing windows or doors

摘要

A cord (5) guided by a deflection device (9) e.g. a roller, is fastened at one end to the frame (2). At the other end, it is fastened to a pulling device with a release mechanism. When this is operated, it pulls the cord, hence closing the open door or window (3). The cord passes from the frame (2) to the roller and into a channel between the e.g. window and frame, or to the pulling device in the channel. The release mechanism is based on electromagnets; when the current is interrupted the pulling device operates.
