FENSTERBALUSTRADE MIT EINEM BEWEGLICHEN OBERGURT

The guardrail window assembly includes a window sub-assembly movable between the floor and ceiling sections of a patio or balcony. A stationary support is mounted on the floor and includes two foreshortened vertical supports rising only partially towards the ceiling section. A crossheader frame (40) is movably retained between the two vertical supports. The crossheader frame (40) is generally rectangularly shaped and the sides of the crossheader carry trolleys that run in tracks provided within the stationary support. In a first position, as shown in window modules (20, 22, 27), the crossheader frame is encased by the stationary support. In a second position, the crossheader frame extends from and frames an area between the stationary support and the ceiling. That area can be open or can be screened, as necessary. A window, consisting of a window pane and a window frame, is movably retained within the crossheader frame and the stationary support. In the first and second positions, the window is disposed within the stationary support. In a third position, as shown in window modules (23, 24, 25) the window is encased by the crossheader frame (40) and therefore closes the framed area. The guardrail window assembly also includes a motor and a pulley drive system for moving the crossheader frame (40) and the window sequentially through the first, second and third positions with respect to the stationary support.
