Abstract

The hinge (10) is intended for a roof window having a frame and a sash, and has a frame hinge part (100) and a sash hinge part (200) configured to assume an angle relative to the frame hinge part (100). Each hinge part (100, 200) has a base plate (110, 210) with a guide track (112, 212) and a link (120, 220), the links (120, 220) being connected to each other at a bearing axle (123). Each link (120, 220) has a first hinged joint (121, 221) to the respective base plate (110, 210) and a sliding joint (122, 222) slidably received in the guide track (212, 112) in the base plate (210, 110) of the other hinge part (200, 100). A pick-up element (130, 230) is connected to the base plate (110, 210) in a second hinged joint (131, 231) and is biased by a spring (140, 240) to act on the sliding joint (222, 122) in the guide track (112, 212), for instance within a predefined angle interval.
