ABSTRACT:
Turnable window arrangement of the kind in which a window sash is capable of being rotated about a horizontal axis through approximately 180.degree. relative to a window frame while the pivotal axis of the sash is moved between upper and lower positions in the frame. A pivot pin is supported horizontally by the sash via a mounting on opposite sides of the upper side portion of the sash. The pivot pin is formed with a head and has a slide portion-supporting lug pivotally mounted thereon. The frame has a first guide groove with which the slide portion is slidably engaged as well as a second guide groove parallel to the first guide groove and receiving the head of the pivot pin. The frame and the sash define a relatively narrow, vertical gap in a direction transversely of the main plane of the window. The lug has a main portion freely pivotable in this gap and made of relatively thin-walled spring steel. The sash is formed with a groove for receiving the mounting supporting the pivot pin.
