Abstract: In the roof window, a stationary primary frame (1) with frame members includes two opposing side members (1a), a first secondary frame includes a sash (2) with two opposing side members (2a), and a second secondary frame including an intermediate frame (6) are provided. A lifting device (7) including a spring assembly (7a) acting on a lifting arm (7b) is inserted between the stationary primary frame (1) and the intermediate frame (6). A top hinge arrangement (8) is connected to the primary frame (1) and to the sash (2) and the intermediate frame (6) to define a first hinge axis (α1) at or near a top of the roof window in a first operational condition of the roof window. To provide a second operational condition of the roof window, the hinge arrangement comprises a set of hinges (10) connected to the intermediate frame (6) and to the sash (2) to define a second hinge axis of the roof window in the second operational condition of the roof window. Each of the hinges (10) comprises a frame hinge part, a sash hinge part, and a movement supporting assembly with a linkage mechanism comprising a number of links and joints.

Abstract: In the roof window, each hinge (110) of the set of hinges comprises a frame hinge part (130), a sash hinge part (140), and a movement supporting assembly comprising guiding means including a linkage mechanism with at least two links (150, 160) providing connection between the sash hinge part and the frame hinge part. Each link is connected to at least one of the frame hinge part and the sash hinge part at a joint and connected to each other. The hinge (110) furthermore comprises a braking device (180) acting on at least one element of the movement supporting assembly over at least a part of the opening and/or closing movement. The braking device (180) comprises one or more friction elements.

Abstract: In the roof window, each hinge (310) of the set of hinges comprises a frame hinge part (330), a sash hinge part (340), and a movement supporting assembly comprising guiding means including a linkage mechanism with at least two links (350, 360) providing connection between the sash hinge part and the frame hinge part. Each link is connected to at least one of the frame hinge part and the sash hinge part at a joint and connected to each other. A force transmission device (370) is provided for exerting lifting assistance to the movement of the sash (2) relative to the frame (1) during opening of the roof window in the mounted condition of the hinge (310). The force transmission device is provided with biasing means selected from the group comprising leaf springs, torsion springs and tension/compression springs. The force transmission device (370) may comprise a pick-up (371) biased by a leaf spring (372) connected to the frame hinge part (330) or the sash hinge part (340) by means of a fastening protrusion (375a) and/or a first abutment protrusion (375b) and/or a second abutment protrusion (375c).

Abstract: In the roof window, each hinge of (1010) of the set of hinges comprises a frame hinge part (1030), a sash hinge part (1040), and a movement supporting assembly comprising guiding means including a linkage mechanism with at least two links (1050, 1060) providing connection between the sash hinge part and the frame hinge part. The links (1050, 1060) of the linkage mechanism are connected to each other in a bearing axle (1055). One or more joints between the links and the frame and sash hinge parts comprises a sliding joint (1056, 1062) cooperating with a guide track (1036, 1045) and another joint may be a sliding joint or a hinged joint (1051, 1061). One or both of the guide tracks (1036, 1045) may comprise a curved portion.
