ABSTRACT:
In a device for opening and closing a window, a casement moves between a closed and an open position with respect to a stationary frame. This is done by a longitudinally displaceable toothed rack, which effects the movement of the casement of a carrier. In order to obtain a space saving, easy to operate device. Not only is the casement moved by the toothed rack, but the casement is also moved by a moveable closing element in the frame between its latching position and unlatching position with a stationary carrier located on the frame. Both carriers are connected respectively to the toothed rack by means of an independent coupling, which is rendered effective and ineffective at an associated change-over location. These two change-over locations are arranged in a specific place in the path of longitudinal displacement of the toothed rack, respond to the associated coupling and are automatically effective.
