Description


[0001] The invention relates to a window frame with fitting, intended for a roof window, opened by rotation of the sash around a horizontal axis, as a pivoting window, or tilting window, or dual-action window: pivoting-tilting window. The window frame according to the invention is intended mainly for a window installed in a roof, with large immersion of the window sash in the layered structure of the roof.

[0002] State of the art. Patent description No. PL 200789 discloses a solution for a window frame of a roof window, having a rectangular recess on its bottom surface, the recess having a support surface being seated on elements of the roof structure. A significant part of this window frame, and consequently of the roof window, protrudes above the roof's surface. Patent description No. PL 214536 discloses a roof window, having a window frame fixed by runners penetrating the roof structure basically perpendicularly to its surface, the runners being covered on the side with a thin layer of thermal insulation. Also in this solution, a significant part of the window frame protrudes above the roof's surface, moreover the fixing runners form thermal bridges, facilitating escape of heat from the attic outwards. In known roof windows being opened at least as pivoting, called also pivot windows or reversible windows, the hinges, using which the sash is mounted, are immersed into the window between the side members of the window frame and the sash, forming thermal bridges with a high share of metal parts.

[0003] Essence of the solution. A window frame with fitting for a roof window, having the form of a frame, particularly a rectangular frame, seated in the roof structure, comprising: a top member, a bottom member, and two side members. At least one structural element of the window frame, connecting it with the roof, is located on the surface of the window frame members, located at the external side of the window, while the structural element connecting the window frame with the roof, protrudes beyond the outline of the window frame members. The window frame is equipped with fitting, constituting at least the fixing set of a window sash, the sash containing a glazing unit, and being situated in the opening of the window frame, at least when the window is closed, particularly a sash being rotated in order to open then window, around at least one horizontal geometrical axis, particularly located slightly above the surface of the window frame. The fixing set of the sash consists of particularly hinges, installed on the structural element of the window frame, connecting it with the roof. The window frame has also installed elements of a set for bolting the sash in relation in the closed position, moreover it mates with shields of gaps between the window frame and the window sash, and with a sealing set in these gaps.

[0004] In the first aspect of the invention, the structural element of the window frame connecting it with the roof, is a support flashing, adjacent to at least three of the window frame members, including both side members, protruding at least sideways beyond the outline of the members. In its members, the window frame has walls made of a material with a low thermal conductivity, preferably a plastic, situated along the support flashing, transversely to its surface resting on the roof. These walls are situated at least at the side of the window sash, forming - on at least three members, the top one and both side ones - a circumferential wall surrounding the opening in the window frame. In the walls situated in the window frame members from the side of the window sash, there are longitudinal grooves, particularly with a T-shaped cross-section. These grooves serve the purpose of mounting the seals situated between the window frame and the window sash. Outside the walls, the window frame members seated in the roof structure, have a filling made of an insulating material, preferably a porous one, with a lower resistance than the material of the walls in the window frame, but with a higher thermal performance than the material of walls. Basically, the external surface of the filling does not require an exposure, but it may be equipped with a second wall the same type of plastic, as the wall from the side of the window sash. A variation of the members is also possible, which do not have a separation of materials to a more mechanically resistant wall and a filling with improved thermal performance, but they are made of a material uniting both these properties. Grooves for the seals are then situated directly in this material of the members.

[0005] In a second aspect of the invention, the structural element of the window frame connecting it with the roof is constituted by bearing strips, adjacent to the side members of the window frame, on the external side of the window. The bearing strips protrude beyond the outline of the window frame members on its opposite sides, and it may be a protrusion of the strips sideways of the window, or a protrusion along the side members, upwards and downwards, beyond the top member and the bottom member of the window frame. The window frame according to the second aspect of the invention has in its members, similarly as according to the first aspect, walls made of a material with a low thermal conductivity, preferably a plastic, which are situated at least from the side of the window sash, forming on at least three members, the top one and both side ones, a circumferential wall surrounding the opening in the window frame. In the walls situated in the window frame members from the side of the window sash, there are longitudinal grooves, particularly with a T-shaped cross-section. These grooves serve the purpose of mounting the seals situated between the window frame and the window sash. Outside the walls, the window frame members seated in the roof structure, have a filling made of an insulating material, preferably a porous one, with a lower resistance than the material of the walls in the window frame, but with a higher thermal performance than the material of walls. Basically, the external surface of the filling does not require an exposure, but it may be equipped with a second wall of a plastic; a variation of the members is also possible, made of a uniform material, with grooves for the seals situated directly in this material - as in the first aspect of the invention.

[0006] The fixing set of the sash, belonging to the fitting system of the window frame, and containing hinges fixed on the structural element of the window frame, connecting it with the roof, that is on the support flashing, or on bearing strips; occurs in three aspects.

[0007] The first aspect of the fitting belonging to the window frame, is constituted by hinges situated on both side members of the window frame, in the middle section of the length of these members, above the middle of the window height, on its external side. The hinges are intended for opening of the window in the pivoting mode, i.e. by rotation of the sash around a geometrical axis, located usually slightly below the middle of the window height, so as to the lower part of the window sash during opening of the window moves towards the exterior of the roof, and the upper part of the sash moves towards the interior of the attic. The hinges, are defined in this description as "pivoting hinges", on the account of opening of the window in the pivoting mode. The hinges are mounted on the external surface of the structural element of the window frame connecting the frame with the roof, that is on the external surface of the support flashing, or on the external surfaces of both bearing strips.

[0008] The second aspect of the fitting belonging to the window frame is constituted by window sash hinges situated near the top edge of the window, serving the purpose of opening of the window in the tilting mode, hereinafter defined as "tilting hinges". The hinges are mounted on the external surface of the structural element of the window frame connecting the frame with the roof, that is on the external surface of the support flashing, or on the external surfaces of both bearing strips. In the tilting hinges, arms are seated, terminated with pivoting hinges, while both the tilting and pivoting hinges, as well as the arms connecting them, are situated on the external side of the window. The hinges according to this aspect, enable using the window as a dual-action window, by opening it as a pivot window or a tilt window. During opening of the window in the pivoting mode, the window sash rotates in the pivoting hinges, as in the first aspect of the fitting, while the tilting hinges are blocked, and the arms connecting both types of hinges rest on the window frame. During opening of the window in the tilting mode, the window sash together with the arms connecting both types of hinges, rotate in the tilting hinges.

[0009] The third aspect of the fitting belonging to the window frame is constituted by hinges for a window sash, situated near the top edge of the window, i.e. tilting hinges, in which the window sash is mounted directly. The hinges are placed on the external side of the window. The window according to the third aspect of the invention is being opened only in the tilting mode.

[0010] In all aforementioned aspects, the window frame with fitting may have an additional frame, preferably wooden, situated at the internal side of the window, that is from the side of the attic. On the additional frame, elements locking the window are installed, mating with locking elements corresponding to them, seated on the frame of the sash. These are for instance bolt sockets, mating with the bolt of the handle. On the other hand, the window frame has on its external surface, on the external side of the window, installation elements for connecting the window frame with the flashings of the window, which seals the connection of the window frame with the roof. Preferably it is an installation frame, upon which properly bent edges of the detailing of the window are laid, resting on the roof and adjacent to the window.

[0011] Advantages of the invention. Thanks to its design enabling its immersion in the roof structure, the window frame with fitting for a roof window for immersing also the the sash of the roof window in this structure, increasing thermal performance of the whole window. Metal elements of the window frame, having large volume and mass, such as: hinges, support flashing, or bearing strips, are situated on the external side of the window frame, and do not have components penetrating the interior of the roof structure, or the interior of the opening in the window frame for a sash; optionally these parts constitute a small share in metal fitting subsets, so there are no thermal bridges in the window frame, which could lead to thermal losses from the attic by outflow of heat to the outside of the building.

[0013] The window frame with fitting for a roof window, according to the invention, is also presented in embodiments not supplemented with a drawing, but described through indication of their mutual features with the drawn embodiments and features differing them from the drawn embodiments.

[0014] Example 1. The window frame has a form of a rectangular frame 1, with the following main elements: two side members 11, a top member 12 and a bottom member 13. On the external side of the window, the window frame has a support flashing 2 in the form of an open frame, placed at the external side of the window on the side window frame members 11 and the top window frame member 12. The support flashing 2 is adjacent to the window frame members: side 11 and top 12 with its flat internal area 21, while it protrudes beyond the outline of the window frame members: side 11 and top 12 with its flat external area 22, sideways and towards the upper section of the roof plane, while being adjacent only partially to terminal fragments of surfaces of these members on the external side of the window. The flat internal area 22 of the support flashing 2 rests on the supporting structure 3 of the roof, on horizontal tile battens 31, being a support for roofing-tiles 32, while the tile battens rest on counter battens 33 laid on rafters 34, being basic supporting elements of the roof structure.

[0015] Both side window sash members 11 have thin walls 14 with a low thermal conductivity, made of a plastic, situated in the window frame from the side of the sash 4 of the window, while the main bulk of the side window frame member is formed by the filling 15 made of an insulating material, particularly a porous one. In the walls 14, T-shaped grooves 16 are situated along the window frame members, and in these grooves seals 17 are mounted, with freely moving flaps adjacent, in a closed window, to the side surfaces of the sash 4. On the external side of the window, the walls 14 have a connecting lip 18, by which these walls are connected with an internal bend 23 of the support flashing. The filling 15 of the side frame members is glued both to the plastic walls 14, and to the support flashing 2 of the window frame. The top member of the window frame (not shown in the cross-section) is built in the same way, and the wall of the frame member situated from the side of the window sash, is connected with the walls 14 of the side members at its ends, forming, together with them, a frame surrounding the opening in the window frame for a sash 1 from at least three sides.

[0016] On the support flashing 2, on its side sections, which rest on the side members 11 of the window frame, on the external side of the window, pivoting hinges 5 are installed, situated slightly above the middle of length of the side window frame members 11. In the pivoting hinges 5, both their stationary parts 51 fixed to the support flashing 2, and moving parts 52, mating with the sash 4 of the window, as well as axes 53 of the hinge, are situated above the support flashing 2, as well as above the glazing unit 41 in the sash 4 of the window, the unit consisting of four panes separated with internal frames. Only a small strip 54 belonging to the moving part 52 of the pivoting hinge, enters partially the space between the side member 11 of the window frame and the side wall 42 of the sash 4, in order to stabilise this part of the hinge on the sash 4. Movable parts 52 of the pivoting hinges 5 are connected with the side walls 42 of the sash 4 using a reinforcing insert 43, placed in the duct of the side wall 42 of the sash 4 on the external side of the window. The movable part 52 of the pivoting hinge 5 is connected with the reinforcing insert 43 using threaded fasteners 55. In the pivoting hinges 5, during opening of the window, the window sash 4 rotates so as to the lower part of the sash, situated below these hinges, moves towards the exterior of the roof, and the upper part of the sash situated above of these hinges moves towards the interior of the attic.

[0017] In the sections rested on the side members 11 and on the top member 12, between its flat internal area 21 and flat external area 22, the support flashing 2 has a lip, forming an open installation frame 24 in these three sections of the flashing, for connection of the detailing 35 of the window, installed in the roof structure, to the support flashing 2. The purpose of the detailing 35 is to seal the mounting of the window in the roof structure. At external edges of its side sections, the support flashing 2 has a series of holes 25 for threaded fasteners, particularly screws, fixing this support flashing to battens 31 of the roof structure. The holes 25 in the support flashing 2 and the threaded fasteners seated in them are covered with the detailing 35.

[0018] Above the support flashing 2, as well as above the pivoting hinges 5, shields 6 of the side gaps are situated, the gaps being located between the side members 11 of the window frame and the sash 4 of the window. The shields 6 (shown in Fig. 2, omitted in Fig. 3) are divided, as a common practice in pivoting windows, and sections of the shields situated in the upper part of the window, are installed immovably on the window frame, while sections of the shields situated in the lower part of the window are installed on the sash and move during opening of the window together with the lower part of the sash, outwards.

[0019] The window frame has also a wooden additional frame 7, located from the side of the attic. In the wooden additional frame 7, locking elements of the window are seated, for instance sockets for a handle bolt, mating with their respective locking elements mounted on the sash 4, in its additional frame 44. Moreover, from the side of the attic, the additional frame 7 has a groove 71, in which an edge of lining 36 of the window opening in the roof is seated; the frame has also an additional groove for mounting of the seal 72, having a free flap adjacent, in a closed window, to the surface of the sash 4. The wooden additional frame 7 of the window frame is fixed to the support flashing 2 using screws 73, placed in bushings 72 running through the side window frame member. Identically, in the section mating with the top window frame member 13, the additional frame is fixed to the upper section of the flashing using screws, and has a groove for the lining.

[0020] Example 2. The window frame has a form of a rectangular frame 1, with the following main elements: two side members 11, a top member 12 and a bottom member 13. On the external side of the window, the window frame has two support strips 8 laid on its side members 11. The bearing strips 8 are adjacent to the side window frame members 11 with their flat internal areas 81, while they protrude beyond the outline side window frame members 11 with their flat external areas 82, sideways and along these members towards the upper (above the window) and the lower (below the window) sections of the roof plane, while being only partially adjacent to the terminal fragments of surfaces of the side members. In both bearing strips 8, their flat external areas 82, as well as sections of the strips protruding outwards along the side members 11, rest on the supporting structure 3 of the roof, on horizontal tile battens 31, being a support for roofing-tiles 32, while the tile battens rest on counter battens 33 laid on rafters 34, being basic supporting elements of the roof.

[0021] Both side window frame members 11 have thin walls 14 with a low thermal conductivity, made of a plastic, situated in the window frame from the side of the sash 4 of the window, while the main bulk of the side member is formed by the filling 15 made of an insulating material, particularly a porous one. In the walls 14, T-shaped grooves 16 are situated along the window frame members, and in these grooves, weather strips 17 are mounted, with freely moving flaps adjacent, in a closed window, to the side surfaces of the sash 4. On the external side of the window, the walls 14 have a connecting lip 18, by which these walls are connected with internal lips 83 of the support flashings. The filling 15 of the side frame members is glued both to the plastic walls 14, and to the support flashing 2 of the window frame. The top member of the window frame (not shown in the cross-section) is built in the same way, and the wall of the frame member situated from the side of the window sash, is connected with the walls 14 of the side members at its ends, forming, together with them, a frame surrounding the opening in the window frame for a sash 1 from at least three sides.
