Description

    Technical Field
  • The present invention relates to a roof window comprising a window frame of a substantially rectangular outline having four longitudinal frame members, wherein at least two adjacent frame members are provided with at least one mounting groove extending along their external surface at least in the neighbourhood of their corner joint, a window sash mounted in the window frame, and at least one corner bracket for mounting said window frame to a roof construction in the area of connection of the adjacent frame members.
  • Background of the Invention
  • Prior art discloses various techniques of fixing roof windows to various roof constructions, in particular to wooden constructions which are in general comprised of rafters and battens perpendicular to each other.
  • Publication WO 99/35355 for example, discloses a mounting bracket comprising a first leg portion for connection with an associated frame member and a second leg portion which is essentially perpendicular to the first leg portion and is to be fastened to the roof structure, where the first leg portion is designed as two leg sections essentially perpendicular to each other for connection with adjacent frame members at the joint between these.
  • Polish utility model application No. 117857 discloses a corner bracket having two arms for fixing to a roof construction, which are provided on their internal side with wings formed in the perpendicular plane, wherein each arm is crowned by an area of overpresses comprising projections having a shape of the outline corresponding to the width of a groove of a window frame, projecting outside the plane of the wings at the length of the groove.
  • Though the above-described prior art brackets improve positioning of a window in a roof construction, a need still exists for providing a roof window the installation of which would be easy and which would be provided with a bracket of a simpler, more economical construction, and the production of which would be easy and less material-consuming than a production of known brackets, wherein such a bracket should additionally facilitate an installation of such a window.
  • Summary of the Invention
  • The present invention provides a roof window of the kind mentioned in the outset which is characterized in that the corner bracket has a form of a single-element metal shape, the thickness of which corresponds substantially to the height of the mounting groove in the frame member, and which comprises the first flat element of a concave L-shaped outline for settling in the mounting grooves of the adjacent frame members and for fixing to the roof construction elements perpendicular to the external surfaces of the frame members, and the second flat element bent perpendicularly to the first element, for fixing to the external surface of the frame member, wherein the section of the edge of the perpendicular bend of the first and second elements is smaller than the overall length of the internal edge of the first element and is distanced in parallel from the remaining section of this edge at a distance corresponding substantially to the depth of the mounting groove in the frame member, wherein the first and the second element is provided with throughout openings for mounting screws.
  • Such a solution significantly simplifies a construction of a roof window and enables for reliable and simple fixing thereof to a roof construction.
  • Preferably the second element of the mounting bracket is bent in the corner area of the internal edges of the first element.
  • This feature advantageously improves dimensional tolerance since the mounting grooves of adjacent frame members may be then slightly shifted with relation to each other without affecting fixing reliability of a window frame.
  • Furthermore, the throughout openings of the first element have preferably a longitudinal cross-section, thus enabling for displacing a frame over a certain range before is finally fixed.

    Detailed description of the invention
  • A window frame 1 of a roof window shown in Fig. 1 is fixed to a roof construction 2 comprised of a number of oblique rafters 21 parallel to each other and a number of horizontal battens 22, 23 parallel to each other and perpendicular to the rafters 21. Rafters 21 are fixedly connected with battens in a typical manner e.g. by means of nails or woodscrews. Each window frame 1 is of a rectangular outline and comprises two side members 11, 12 extending parallel to the rafters 21 and two horizontal members 13, 14 extending parallel to the battens 22, 23. Each window frame member 11-14 is provided with two mounting grooves 15, each extending circumferentially along the external surface of the window frame 1. The window frame 1 is fixed to the roof construction 2 by means of four corner brackets 3 mounted to the battens 23. A set of brackets for one window frame comprises two symmetrical "left" brackets (located in the bottom left and top right corners of the window frame 1 shown in Fig. 1) and two symmetrical "right" brackets (located in the bottom right and top left corner of the window frame shown in Fig. 1).
  • As presented in Figs. 2 and 3, each bracket 3 has a form of a single-element metal shape having constant thickness and comprising the first flat element 32 settled in mounting grooves 15 of the adjacent frame members 11 and 14 and fixed to the batten 23 of the roof construction 2, and the second flat element 31 perpendicular to the first element 32 and fixed to the external surface of the frame member 11, which is perpendicular to the surface of the first element 32.
  • The elements 31, 32 are fixed to the roof construction 2 and to the frame members by means of screws 16 running through throughout openings 311, 321 and 322. Longitudinal openings 322 of the first element 32 of the bracket provide a certain tolerance for a fixation of the window frame 1 to the roof construction thus enabling for a limited displacing thereof, whereas after final positioning of the frame, it is fixed by means of screws running through circular openings 321.
  • Figs. 4 and 6 present the "right" bracket from Figs. 1, 2 and 3 in axonometric, top and side view, respectively.
  • The first element 32 of the bracket has a form of a L-shaped flat plate, the thickness (g) of which corresponds to the height (h) of the mounting groove 15 (cf. Fig. 3), wherein the external corners of the plate are slightly chamfered. Furthermore the first element 32 has four throughout openings 321 arranged in pairs in its opposite corners and two throughout openings of a longitudinal cross-section in parallel relative to arms of this element.
  • From the internal section 3231 of the edge 323, in the area of the corner of the internal edges 323, 324 of the first element, the second element 31 is bent perpendicularly to the first element 32. The second element 31 has a form of a flat plate having a shape of a right-angled triangle, one of the catheti 312 of which is perpendicular to the plane of the first element 32 and the hypotenuse 313 of which adjoins the internal corner of the first element 32.
  • A section of the edge 3231 of the perpendicular bend of the second element 31 is distanced in parallel from the remaining section of this edge 3232 at a distance (d) substantially corresponding to the depth (b) of the mounting groove 15 formed in the frame member 11 (cf. Fig. 3).
  • The above described construction has only an illustrative character. The second element 32 of a bracket according to the present invention may obviously have another shape and may be directed downwards or upwards relative to the plane of a batten 23 of a roof construction 2. In particular a window according to the present invention may be fixed using four identical brackets, the second 31 of which would be directed both downwards and upwards (accordingly diagonally over a the window frame).
