[0018] Embodiments of the present invention are depicted in the figures, of which Fig. 1 shows a first implementation of the profile in an unhinged skylight, Fig. 2 shows a second implementation of the profile in an unhinged skylight, Fig. 3 shows a first implementation of the profile in a hinged skylight, and Fig. 4 shows a second implementation of the profile in a hinged skylight. Detailed description

[0019] The roof skylight 1 shown in cross-section in Fig. 1 as a first implementation of an adjustable glazing frame profile 2 mounted unhinged to the curb 3 of the roof skylight 1 comprises a transparent panel 4 with an upper plane sheet 5 and a lower plane sheet 6 separated by a spacer profile 7. The upper plane sheet 5 defines an upper side surface 8 of the panel 4, and the lower plane sheet 5 defines a lower side surface 9 of the panel 4. The lower plane sheet 5 is a laminated glass sheet comprising two tempered glass panes 10, 11 with a lamination layer 12 in between.

[0020] The curb 3 extends downwards to a roof surface (not shown) with an opening defined therein (not shown), which is enclosed by the curb 3. The upper edge 13 of the curb 3 is enclosed by a top frame 14 that is fastened to the curb 3 by means of screws 15. The top frame 14 extends down along a part of a sloping outer side 16 of the curb 3 to cover an upper edge of roofing felt (not shown).

[0021] The glazing frame profile 2 comprises an anchoring part 17, which is fixed by means of substantially horizontal anchoring screws 18 to the top frame 14. The top frame 14 is provided with a recess 19 in an outer, substantially vertical surface 20, the recess 19 being of a tapering cross-section for guiding the position of the horizontal anchoring screws 18 when being driven into the top frame 14. The anchoring part 17 having an upwardly facing support element 21 arranged to support the lower side surface 9 of the panel 4 with a gasket 22 in between.

[0022] The glazing frame profile 2 furthermore comprises a fastening part 23 with a downwardly facing clamping element 24, which engages the upper side surface 8 of the panel 4 with a gasket 22' in between for clamping the panel 4 between the upwardly facing support element 21 and the downwardly facing clamping element 24.

[0023] The anchoring part 17 and the fastening part 23 are mutually displaceable in the vertical direction in order to be able to adjust the distance between the support element 21 and the clamping element 24 to the thickness Tp of the panel 4 between the lower side surface 9 of the panel 4 and the upper side surface 8 of the panel 4.

[0024] The anchoring part 17 and the fastening part 23 are provided with two sets of abutting bearing surfaces 25, 26, 27, 28 that are mutually displaceable in the vertical direction when the anchoring part 17 and the fastening part 23 are mutually displaced to accommodate the distance between the support element 21 and the clamping element 24 to the thickness of the actual panel, i.e. the vertical distance between the lower side surface 9 of the panel 4 and the upper side surface 8 of the panel 4. The abutting bearing surface 25, 26, 27, 28 extends in the vertical direction, i.e. in the direction of the mutual displacement, wherein two abutting surfaces 25, 28 are arranged on the anchoring part 17, whereas the other two abutting surfaces 26, 27 are arranged on the fastening part 23. The abutting surfaces 25, 26, 27, 28 are arranged in two sets of abutting surfaces, where a first set of abutting surfaces 25, 26 comprises an abutting surface 25 of the anchoring part 17 and an abutting surface 26 of the fastening part 23, and the second set of abutting surfaces 27, 28 also comprises an abutting surface 28 f the anchoring part 17 and an abutting surface 27 of the fastening part 23. The two sets of abutting bearing surfaces 25, 26, 27, 28 have a mutual horizontal distance, perpendicularly to the vertical direction of displacement, of 10 mm to ensure stability of the glazing frame profile 2 when adapted to various thicknesses of the panel 4.

[0025] Each of the four bearing surfaces 25, 26, 27, 28 of the two sets of bearing surfaces has an extent in the direction of displacement of 8 mm.

[0026] In the present example, the panel 4 extends in the horizontal plane and the anchoring part 17 and the fastening part 23 of the glazing frame profile 2 are mutually displaceable in the vertical direction to clamp the panel 4. More generally, the panel 4 of a roof skylight 1 according to the invention may extend at various angles to horizontal, and the parts 17, 23 of the glazing frame profile 2 are arranged mutually displaceable in a direction perpendicularly to the plane in which the panel 4 extends.

[0027] The anchoring part 17 and the fastening part 23 are jointed and clamped around the panel 4 by means of a plurality of clamping screws 29 having an external thread engaging a side surface 30 of a separation wall 31 of the fastening part 23, where the opposite side surface of the separation wall 31 constitutes one of the bearing surfaces 26 of the fastening part 23.

[0028] The clamping screws 29 extend from the anchoring part 17 into the fastening part 23, and the heads 32 of the clamping screws 29 engage an abutment surface 33 of the anchoring part, the abutment surface 33 extending substantially parallel to the lower side surface 9 of the panel 4 at a smaller distance to the upper side surface 8 of the panel 4 than the distance between the upper side surface of the panel 8 and the lower side surface 9 of the panel 4. Thus, the abutment surface is arranged at a higher level than the lower side surface 9 of the panel 4 and thereby a higher level than the upwardly facing support element 21 in order to prevent condensing water forming inside the glass frame profile 2 from draining out through the openings for the clamping screws 29 in the abutment surface 33.

[0029] A plurality of anchoring screws 18 are provided between the anchoring part 17 and a top frame 14 of the curb 3 for fastening the glazing frame profile 2 to the curb 3. The anchoring screws 18 extends horizontally in the present embodiment, more generally the anchoring screws 18 extend parallel to the plane in which the panel 4 extends. The anchoring screws 18 are situated at a level closer to the roof surface than the heads of the clamping screws 29.

[0030] The upper edge 13 of the curb 3 supports the glazing frame along all four sides, and the outer edge 35 of the lower side surface 9 of the panel 4 extends over the full width of the upper edge 13 of the curb 3 along the four sides of the curb 3, which hides the edge arrangements of the panel 4, such as the glazing frame profile 2 from sight from inside the building through the roof opening and will allow a maximum amount of daylight to enter the building through the skylight 1.

[0031] In Fig. 2, a second implementation of a roof skylight with the profile is shown in cross-section, where the thickness Tp of the panel 4 is increased compared to the first implementation of Fig. 1, in that the panel 4 comprises a middle plane sheet 36 separated from the lower plane sheet 6 by a second spacer profile 7'. Note that the clamping screws 29 are longer in this implementation than in the first implementation due to the increased thickness Tp of the panel 4.

[0032] In Fig. 3, a third implementation of a roof skylight 1 is shown in cross-section, where the panel 4 is identical to the one shown in Fig. 1, but a second frame profile 37 is situated between the top frame 14 and the glazing frame profile 2, so that the glazing frame profile 2 is attached to the second frame profile 37, which is fixed to the top frame 14 by means of fixing screws 38. The second frame profile 37 has along the side of the curb 3 shown in Fig. 3 a hinge 39 allowing the panel 4 to be switched between an open and a closed position of the roof skylight 1.

[0033] In Fig. 4, the panel 4 of Fig. 2 is applied in a roof skylight 1 comprising a second frame profile 37 as shown in Fig. 3, and this cross-section represents a fourth implementation of the invention.List of reference numbers
