A skylight or roof hatch that is manually opened and closed. The skylight is formed of a window mounted to a casing frame by way of one or more hinges, which allows the window to open and close. One or more gas springs mounted between the window and casing frame are configured to exert force against the inside of the window. The gas springs are used to urge the window into an open position. Once in the open position, the window is closed by overcoming the biasing force exerted by the gas springs. This is achieved by winding in a cable that is connected to the window. A single pulley wheel that is mechanically linked to other mechanical elements is utilized to spool in the cable connected to the window in order to close the window and to unlock a reel lock to allow for automatic opening of the window.

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).

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 (?1) 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.

The present disclosure relates to an aperture cover such as a window or a door. The aperture cover comprises a vacuum insulated glass unit (3), and a frame (2, 17) such as a sash. The frame (2, 17) comprises elongated structural frame members (8) which together encloses a frame opening (2a). The vacuum insulated glass unit (3) overlaps (18) at least one of the elongated structural frame members (8) so that the edge surface (7) of the vacuum insulated glass unit (3) extends beyond the outer side surface (14) of the overlapped elongated structural frame member (8). The frame (2) moreover comprises an elongated connection profile (6) comprising a connection wall member (6a) which extends parallel to the overlapped structural frame member (8) and is connected to at least one of the outer major surfaces (S1, S2) of the vacuum insulated glass unit (3), and the elongated connection profile (6) comprises a fixation member (6b) which is connected to the overlapped structural frame member (8).

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.

The present disclosure relates to a vacuum insulated glass (VIG) unit frame assembly (10), wherein said vacuum insulated glass unit frame assembly (10) comprises: a vacuum insulated glass unit (1), anda frame (20) comprising elongated frame profile arrangements (20a-20d) which frames said vacuum insulated glass unit (1) in a frame opening (21). One or more of said frame profile arrangements (20a-20d) comprises a holding part (28), wherein said holding part (28) holds the vacuum insulated glass unit (2) between first and second holding members (22, 23 28a, 28b,) arranged at opposite outwardly facing surfaces (4a, 4b, 15, 35a) of the vacuum insulated glass unit (1), and one or more resilient suspension elements (45a, 45b) is compressed between a first of said holding members (22, 23 28a, 28b) and one of said opposite outwardly facing surfaces (4a, 4b), and wherein one or more resilient suspension elements (45a, 45b) is compressed between a second of said holding members (22, 23 28a, 28b) and the other of said opposite outwardly facing surfaces (4a, 4b). Said compressed, resilient suspension elements (45a, 45b) provides a holding force (F1, F2) towards said opposite outwardly facing surfaces (4a, 4b, 15, 35a) of the vacuum insulated glass unit (1) so as to suspend the vacuum insulated glass unit (1) between said first and second holding members (28a, 28b), and each of said compressed, resilient suspension elements (45a, 45b) are configured to be further compressed or expand in response to a thermal deflection of the edge (8a-8d) of the VIG unit (1) due to a temperature difference (AT=71?72) between the two glass sheets (2a, 2b). The disclosure additionally relates to a vacuum insulated glass unit and a retrofitting frame system.
