<p>The invention relates to an apparatus for the motorized opening and closing of windows, doors or the like, having a swivel rod (10), extending from the wing (3) to the frame (2), and a motor carrier (18) displaceable relative to the swivel rod (10), and proposes, for the purpose of avoiding an excess length projecting in a disturbing manner into the room, whilst at the same time ensuring optimum actuation, that the motor carrier (18) and swivel rod (10) should swing to into a position parallel to the wing plane in the final phase of the closing movement.</p> |
