ABSTRACT:
A driven part can be pivotably mounted to the door frame so that, in a starting position, it engages a driving part fixed to the leaf frame in order to fix the position of the door leaf with respect to the door frame. An electromagnetic brake generates a moment to retain the driven part in the starting position when electrical current is supplied, and allows the driven part to pivot from the starting position when electrical current is not supplied. The driven part is held in the starting position when the driven part returns to the starting position and no moment is generated by the electromagnetic brake.
