摘要

The present invention concerns an improved attachment for a frame and window which opens in the Italian fashion, extending the upper part of the openable window outwardly upon opening thereof and by rotary movement of a stop member (14) through 180 DEG , permitting the window to be opened into a service position for simple ventilation and closure thereof, or into cleaning open position and closure thereof, with automatic locking in the cleaning open position. The attachment uses two opening/ closing devices (4) each with a ramp- bearing keeper member (5), slideway (8), shoe (13), catch stop member (14) and strut member (16) with roller (7) cooperating with an aperture (6) of the keeper member (5). The attachment makes it possible to clean the outside face of the window from inside a building fitted with the frame and window. IMAGE
