摘要

The guide between the frame and the sash window displaces the sash window transversely to the direction of sliding over a relatively small distance, which is sufficient to bring the sash window at least in the closed condition into a sealing contact with the frame with a seal (10) provided between the window and frame. The guide also brings the sash window, while opening it, out of sealing contact with the frame. The sash window assembly comprises a frame (1) with a sash window (2) being vertically slidable in it. The guide has a first guide in form a slot connected to one of the frame and the sash window for sliding the sash in a vertical manner, and a second guide in form of a pin (9) and slot connected to the other of the frame and the sash for guiding the sash at an angle to the direction of sliding. The slot makes the pin move obliquely upwards when the sash window is opened.
