Abstract
A displacement arrangement for moving a window sash or a door leaf has a control part which is displaced by an actuating device relative to a guide part which can be mounted fixedly on the sash/leaf. A first control projection is provided between the control part and actuating device and engages in a first control slot of the control part and engages in a first guide slot of the guide part. The first control projection has a first rolling bearing for bearing on the first guide slot. The first control projection can have a second rolling bearing for supporting on the first control slot. A supporting rolling bearing can be provided between the guide part and the control part. The displacement arrangement allows the generation of a high contact pressure of the sash/leaf on the fixed frame under moderate operating forces and thus good sealing of the window or the door.
