Electromagnetic opening/closing device for use on a swiveling door leaf has an electrically active part in a door frame with an electromagnetic coil creating an electromagnetic field, two pole flanges and an antipole piece

摘要

An interlocking connection occurs between a swiveling door leaf (8) and a door frame (1), as soon as the door leaf is in a closed position on a doorstop (20). This connection is caused by an opening/closing device (24) creating an electromagnetic field and fitted in the door frame. An antipole piece (11) in the moving door leaf closes the lines of electric flux for the electromagnetic field of the opening/closing device.
