Abstract:
A device for automatically closing a window which is initially placed an open position, the closing of the window during a closing operation placing the window in a closed position, the window being mounted in a frame supported by a building, the device comprising: a drive device, the drive device including a spring, the spring being adapted to be tensioned when the window is placed in the open position, the spring being adapted to supply stored energy for automatically closing the window during the closing operation to close the window, a traction mechanism, the traction mechanism being adapted to be located between the window and the frame, the traction mechanism being configured to be driven by the drive device to automatically close the window during the closing operation, an actuating device, the actuating device being movable between a deactuated position and an actuated position and being adapted to open the window during said movement, wherein the actuating device is coupled to the traction mechanism such that movement of the actuating device from the deactuated position to the actuated position drives the traction mechanism to tension the spring, whereby a pulling motion applied to the actuating device simultaneously tensions the spring and is adapted to place the window in the open position, a locking device, the locking device initially being released by the actuating device and adapted to permit the window to be placed in the open position, and the locking device automatically being adapted to lock the window to the frame in the closed position after the window is closed, anda timing element, the timing element being installed in the drive device, the timing element being adapted to control the timing of commencement of the automatic closure of the window.
