Title: Device for operating hinged or guided closures

Abstract: A device for automatically closing a closure installation (such as a window or a door) includes a drive device, a traction mechanism, a spring, an actuating device and a locking device. The closure installation is mounted in a frame supported by a building. The traction mechanism is located between the closure installation and the frame, and is driven by the drive device to close the closure installation. The spring is tensioned when the closure installation is placed in the open position, and supplies the energy to the drive device which is required to close the closure installation. The actuating device is used to initially place the closure installation in the open position. The actuating device tensions the spring when the closure installation is placed in the open position. The locking device is initially released to permit the closure installation to be placed in the open position. After the closure installation is closed, the locking device automatically locks the closure installation to the frame in the closed position.
