A window to be mounted and a method for mounting a window in a flat roof structure, the window comprising a window sash (3) and a window frame (4). A bottom sash member (3a) is pivotall? connected to a bottom frame member (4a) by means of a pivot hinge defining a pivot axis. Two compression springs (10, 11) connect said window sash (3) and said window frame (4) such as to provide a spring force on said window sash (3) towards an open position. Said compression springs (10, 11) connect a top sash member (3b) to a top frame member and are adapted to pivot in directions towards or away from each other during pivoting of said window sash in relation to said window frame between said open and a closed position of said win- dow. A set of parts for spring-loading a window sash in relation to a window frame, comprises a compression spring (10, 11) and two bearing members (12, 15). At least one of said bearing members (12,15) is provided with an oblong tray (15a), and at least one of the heads (18, 19) of said compression spring (10, 11) is formed as a ball-like, preferably hemispherical joint. |
