PCT No. PCT/DK89/00073 Sec. 371 Date Oct. 1, 1990 Sec. 102(e) Date Oct. 1, 1990 PCT Filed Apr. 5, 1989 PCT Pub. No. WO89/10460 PCT Pub. Date Nov. 2, 1989.A window, particularly designed to be installed in an inclined roof, comprises a top-hinged sash which via a lifting arm is connected with a slide shoe displaceable along a guidance of a lateral frame member. An intermediate member is provided with a transverse pin adapted to be connected with a pocket in the top side of the slide shoe, and the intermediate member is loaded or biased in a direction towards the lower end of the guidance by means of a spring. A spacer serves to hold the intermediate member ready for engagement. When the window has been installed in the roof, the appropriate pocket to be engaged by the transverse pin is selected with due regard to the roof inclination, i.e. the pocket resulting in a desired opening force acting on the sash, which is then swung open until the transverse pin engages the selected pocket, whereupon the sash is swung slightly in its closing direction to release the spacer for removal. The spring may be inserted in the window in prestressed condition by the manufacturer and yet be prevented from exerting any opening force on the sash during handling or installation of the window. |
