• the roof window illustrated in the Figures com- prises a main frame structure generally designated 1 and having in the embodiment shown a top member 2, a bottom member 3 and two side members 4, 5.
• the roof window is intended to be installed in a roof surface, in a manner known per se, by stationarily connecting the main frame structure 1 to the roof structure by means of any suitable supporting means, eg. mounting brackets secured to the main frame side members 4, 5.
• a window frame structure generally designated 6 and having a top member 7, a bottom member 8 and side members 9, 10 encasing a glazing element 11 is in the embodiment shown connected with the main frame structure 1 at the respective top members 7 and 2 by means of a hinge connection which in the embodiment shown comprises two pairs of first and second connecting members 12, 13 shown in Fig. 3.
• a hinge connection which in the embodiment shown comprises two pairs of first and second connecting members 12, 13 shown in Fig. 3.
• the elements of one of the pairs only will be referred to. It should be remarked that the elements of the other pair are designed in substantially corresponding manner.
• the first connecting member 12 is secured in a transverse groove-like depression of the main frame top member 2 by means of an elongate flange part 12a formed integrally with a projecting elongate engagement part 12b which is received in a corresponding engagement part in the form of a sub- stantially V-shaped track 13b of the second connecting member 13 which in turn is secured to the window frame top member 7 by a flange portion 13a.
• the engagement parts 12b, 13b are formed with a respective part-cylindrical engagement surface to define a pivot axis of the window frame structure 6 with respect to the main frame structure 1.
• the V-shaped track 13b is formed with an included angle in the range from 20° to 30° corresponding to the desired range of opening angle in which the window is operative.
• a securing device is provided in order to maintain the engagement between the connecting members 12, 13 during opening of the window frame structure 6 with respect to the main frame structure 1.
• the securing device comprises a torsion member 14 posi- tioned at a respective end of the top members 2, 7 of the main frame and window frame structures 1, 6.
• the torsion member 14 includes a first arm 15 and a second arm 16 extending substantially perpendicularly to each other originating from a connecting point 17.
• the connecting point 17 is positioned substantially on the pivot axis of the window. In the embodiment shown in Figs .
• the first arm 15 comprises two mutually spaced and substantially parallel limbs 15a, 15b forming at the end opposite said connecting point 17 a narrow elongated U and is received in a longitudinal channel 12c of elongate cross-section formed in the engagement part 12b of the first connecting member 12.
• engagement means in the form of an upstanding pin 18 are provided.
• the upstanding pin 18 is releasably connected with corresponding engagement means positioned on the adjacent window frame side member 9, 10 and comprising a block 19 having a recess 19a.
• the engagement means of the second arm 16 of the torsion member 14 includes a fork portion 20 and the corresponding engagement means of the window frame side member 9, 10 includes a protruding pin 21 which is received in the fork portion 20 within said predetermined range of the opening angle.
• the torsion member 14 is torsionally biased in the opening direction of the window frame structure 6 with respect to the main frame structure 1.
• the upstanding pin 18 is thus received in the recess 19a in the block 19 on the window frame side member 9, or, in the alternative embodiment of Fig. 8, the protruding pin 21 abuts the fork portion 20. Consequently, by turning about the connecting point 17, the second arm 16 of the torsion member 14 follows the pivoting movement of the window frame structure during opening of the window until the torsion member 14 reaches its relaxed condition which may be chosen according to the desired predetermined range of the opening angle.
• the spring bias is illustrated in Fig. 5, the second arm 16 in the absence of physical load thus assuming the position indicated by the dot-and-dash line, in which the second arm 16 extends in a direction forming an angle with the plane defined by the first arm 15.
• a torsion member comprising a coil spring 25 is connected with the main frame structure.
• the coil spring 25 acts on a lever 26 in a point of action, preferably situated on the pivot axis of the window frame structure, at one end of the lever and engagement means are provided at the opposite end.
• the engagement means may as shown be designed as in the embodiment of Fig. 7, or, alternatively, as in the Fig. 8 embodiment. It is preferred that one torsion member is positioned at a respective end of the top members of the main frame and window frame structures. However, it is conceivable that only one torsion member is utilized. Installation of a roof window according to the invention may thus be performed in the following manner:
• the main frame structure 1 is secured to the roof surface by appropriate supporting means. Following this operation, the window frame structure 6 is positioned in such a way that the window frame top member 7 is positioned above the main frame top member 2 so that the window frame structure 6 rests on the first connecting member 12 by its glazing element 11, the window frame structure forming an angle with the main frame structure.
• the connecting members 12, 13 of each of the pairs forming the hinge connection are brought into mutual engagement by pulling the window frame structure 6 in the direction of the main frame bottom member 3, the window frame structure 1 now sliding on the first connecting member 12 by a guide member 22 (shown in Fig. 3) provided in the window frame top member 7.
• the window frame structure 6 is turned in the closing direction about the pivot axis at the top members 2, 7, and the securing device is automatically activated, as illustrated in Fig. 7, as the upstanding pin 18 is received in the recess 19a in the block 19, alternatively as the protruding pin 21 is engaged in the fork portion 20.
• the torsion member 14 thus provides a useful guide means assisting to secure accurate positioning of the window frame structure 6 with respect to the main frame structure 1 when the window frame structure is pivoted into a position within the predetermined ventilating range. tilating range.
• lever 26 of the embodiment of Fig. 9 may be directed slightly outwards with respect to the longitudinal direction of the adjacent window frame side members.
• the window frame structure 6 may now be brought to its closed position without any risk of disengaging the connecting members 12, 13 from each other.
• Operation of the window ie. opening the window frame structure to a ventilating position, may be carried out by means of a window operator 23 mounted at the bottom member 3 of the main frame structure.
• the window operator is an electrically operated chain operator including an operating chain 24 de- tachably connected with the bottom member 8 of the window frame structure.
• the operative length of the operating chain 24 ' is chosen such that it is only possible to open the window by means of the operator to a maximum ventilating position falling within the predetermined range of the opening angle, in which the securing device is active.
• the operating chain 24 is released from the window frame bottom member 8 and the window frame structure 6 is pivoted further about its pivot axis, whereby the engagement means on the torsion member, as shown in Fig. 6, are released from the engagement with the corresponding engagement means on the window frame strueture .
• the invention should not be regarded as being limited to the embodiments described in the above but various modifications and combinations of the shown embodiments may be carried out without departing from the scope of the following claims.
• the hinge connection may be positioned arbitrarily in the skylight or roof window to provide a pivot axis at eg. a bottom or side member.
