Description

Technical Field

[0001] The present invention relates to a roof window, which includes a frame, a window frame and a window pane, wherein the frame includes a set of frame members, the set of frame members includes a top frame member, two side frame members and a bottom frame member, and the window frame includes a set of window frame members, the set of window frame members includes a top window frame member, two side window frame members and a bottom window frame member. Background Art

[0002] There are various types of roof windows installed on sloping roof surfaces. When selecting a roof window type for a specific installation location in a building, parameters such as operability, thermal performance, weatherproofing, and appropriate aesthetics for the building's interior are generally given considerable weight; however, it is often desirable, and in some areas, necessary, to also consider external appearance. This applies particularly to roof window installations within protected areas, where building regulations may require that roof windows meet standard or local requirements. Therefore, certain requirements apply depending on whether the installation involves a new roof window or replacing an existing window or skylight as part of a renovation or refurbishment project.

[0003] Traditionally, windows or skylights were made of cast iron and a single glass pane, separated by one or more cast iron glazing bars, and their thermal efficiency left room for improvement. To meet the energy performance required by modern building regulations, energy-efficient roof windows are often equipped with insulated panes and have begun to mimic the style of traditional skylights.

[0004] In many installation situations, there's also a requirement for economical roof windows to be installed with a "low profile," meaning the height of the roof window protruding above the surrounding roof is as low as possible. This is particularly true on buildings with generally flat roofing materials such as slate or shingles. To meet this requirement, most major roof window manufacturers allow for installation in at least two layers, thus accommodating a wide range of roof profile heights and installation conditions.

[0005] With growing awareness of environmental issues and a desire to reduce or even eliminate the climate footprint of products, there is also a need for more environmentally friendly products in terms of manufacture, supply, installation and use.

[0006] Considering all the above requirements, there is an ongoing task to improve roof windows for protection purposes. Summary of the Invention

[0007] Against this background, it is an object of the present invention to provide a roof window with which the manufacturing and assembly processes are made more flexible.

[0008] This and other objects are achieved by a roof window of the type mentioned in the introduction, which is further characterized in that each frame member comprises a plurality of receiving structures located inside, outside, inside and / or outside the corresponding frame member, each of said receiving structures being configured to interact with an auxiliary device in the assembled state of the frame.

[0009] During the manufacture of the roof window, auxiliary equipment such as sealing profiles, covers, external insulation, internal linings, mounting brackets, etc. are selected according to a number of parameters such as the size of the roof window, thermal insulation, acoustic insulation requirements, etc. The well-defined receiving structure also makes it easy to place the auxiliary equipment in the correct position.

[0010] In one embodiment, at least the top frame member and the two side frame members have substantially the same cross-section. This provides substantial improvements in manufacturing, storage and assembly.

[0011] The bottom frame members may include outer panels and separate inner panels that are manufactured to specifications and subsequently joined by, for example, mortise and tenon or dovetail joints.

[0012] In a currently preferred embodiment, the first receiving structure comprises a lining groove located on the inside of each frame member, the lining groove being configured to interact with a set of internal lining panels. This not only facilitates installation, but also facilitates retrofitting of windows or lining panels.

[0013] In conjunction with an embodiment in which the bottom frame member comprises a separate plate, the first groove portion can be provided in an outer plate and the second groove portion can be provided in a separate inner plate, with the first groove portion and the second groove portion forming the lining groove in the assembled state of the frame. This emphasizes the flexibility achieved in manufacturing and assembly.

[0014] In a particularly advantageous embodiment, the third receiving structure comprises a first external groove located on the outside of the frame member and configured to interact with the engagement means of the mounting bracket and / or with the protrusion of the insulation frame. In this way, the first external groove serves as a multi-purpose groove.

[0015] In another embodiment, the sixth receiving structure comprises a second outer groove located on an outer side of at least the side frame member, the second outer groove being configured to interact with the engagement means of the mounting bracket.

[0016] The latter embodiment is particularly advantageous in combination with a further development in which the engagement means of the mounting bracket engage with the second outer groove, in particular also with the first outer groove.

[0017] Other proposed preferred embodiments and other advantages will be apparent from the following detailed description and accompanying drawings.

[0018] Features described in relation to one of these aspects may also be incorporated into another aspect, and the advantages of that feature apply to all aspects in which it is incorporated. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] In the following detailed description, preferred embodiments of the present invention will be described. However, it should be understood that features of different embodiments are interchangeable between the embodiments and can be combined in different ways unless otherwise specifically indicated. It should also be noted that for clarity, the dimensions of certain components shown in the drawings may differ from the corresponding dimensions in actual implementations.

[0059] Note that terms such as "upper," "lower," "left," "right," "outer," "inner," "exterior," and "interior" are relative and refer to the perspective at issue. Generally speaking, when referring to the exterior side, this refers to the side of the roof window that faces the exterior, or the exterior of the building, when installed. Conversely, the interior side refers to the side that faces the interior of the building, typically the room below, including any light wells. Terms such as "outward" and "inward" refer to directions generally perpendicular to the inward-outward direction, with the center of the roof window as their base point.

[0060] General description of roof windows - Figure 1 and Figure 2

[0061] First refer to Figure 1 and Figure 2 , a roof window 1 is shown. The roof window 1 is intended to be installed on a sloping roof surface (not shown).

[0062] Roof window 1 includes a frame 2, a sash 3, and a window pane 4. Frame 2 includes a set of frame members, including a top frame member 21, two side frame members 22, 23, and a bottom frame member 24. Accordingly, sash 3 includes a set of frame members, including a top sash member 31, two side sash members 32, 33, and a bottom sash member 34. Although frame 2 and sash 3 are described as rectangular structures, some of the principles of the proposed concept can also be applied to other geometric shapes.

[0063] As will be described in further detail below, the pane 4 includes a plurality of edge portions that are typically associated with the components of the window frame 3. When in the closed position, the outer pane surface 4e defines the plane of the roof window 1 in the assembled state of the roof window 1. The assembled condition of the roof window 1 is reached when the main components of the frame 2 and the window frame 3 have been assembled and connected to one another, such as in the installation position in which the roof window 1 is ready for use. Accordingly, the assembled condition of the window frame 3 is reached once the main components of the window frame 3 have been assembled, and the assembled condition of the frame 2 is reached when the main components of the frame 2 are assembled.

[0064] The inner pane surface 4i faces the interior, typically the room below the roof surface of the building in which the roof window 1 is installed. The outer pane surface 4e is fitted with a glazing strip 45, and the inner pane surface 4i is fitted with a glazing strip cover 46. Although less practical, a two-part pane is also possible, where the two panes are divided into two equal parts by a continuous glazing strip. In wide roof windows, more than one glazing strip may be provided, for example, two glazing strips dividing the surface of the pane visible from the outside into three parts.

[0065] In the illustrated embodiment, the sash 3 is capable of opening relative to the frame 2 to achieve one or more open positions. In such open positions, the sash 3 and the window pane 4 are moved out of the plane of the roof window 1. As will be described below, the sash 3 is shown as being top-hung, meaning that during normal use, the sash 3 rotates about a generally horizontal hinge axis at or near the top frame member 21 and the top sash member 31. However, it is contemplated that some of the principles of the proposed roof window concept may be applied to different types of windows having other opening arrangements or provided as fixed skylights.

[0066] Figure 1 and Figure 2 Other details shown in FIG include an operating assembly 5, shown here as a manual winder or screw jack. Other operating assemblies may also be present.

[0067] Also shown is a typical mounting bracket 6 forming part of a plurality of mounting brackets that form a load transferring connection between the roof window 1 and a surrounding roof structure (not shown). Such a roof structure may include rafters and battens, plywood or other construction materials.

[0068] Finally, there is shown an insulating frame 7. Insulation by an insulating frame is optional and may be provided along only some of the frame members, or around all four frame members 21, 22, 23, 24 as shown.

[0069] In the following description of various embodiments, elements having the same or similar functions are always provided with the same reference numerals. Appropriate variations and modifications will be apparent to those skilled in the art.

[0070] Mounting bracket and roof window having a set of mounting brackets - Figures 3 and 4

[0071] Typically, roof windows, e.g. Figure 1 and Figure 2The roof window 1 shown in FIG is equipped with a set of mounting brackets 6. As indicated, two mounting brackets 6 are fastened to each side frame member 22, 23. In the following, a single mounting bracket 6 associated with one side frame member 22 will be described. The set of mounting brackets 6 will generally be identical, although variations are possible.

[0072] The mounting bracket 6 comprises a first bracket leg 61 for fastening to the roof structure and a second bracket leg 62 for fastening to the frame 2 of the roof window 1. To this end, the second bracket leg 62 includes an engagement mechanism that interacts with a corresponding receiving structure on the outer side of the side frame member 22 of the frame 2 of the roof window 1. This ensures that the mounting bracket 6 is correctly positioned on the side frame member 22 and facilitates the installation process. The positioning of the mounting bracket 6 can be indicated in the longitudinal direction and height direction of the side frame member 22, for example, by appropriate markings and / or holes. The first bracket leg 61 of the mounting bracket 6 is connected to the second bracket leg 62 via a bend 614.

[0073] In the embodiment shown, the second bracket leg 62 is provided with a first engagement means 624 at a first portion 621 of the second bracket leg 62 and with a second engagement means 629 at a second portion 626 of the second bracket leg 62 .

[0074] Of the two engagement means 624 , 629 , the second engagement means 629 is configured to assume an inactive position and an active position, of which the active position is shown.

[0075] The first engagement means 624 is configured to be received in one receiving structure of the outer side of the frame member 22 when the mounting bracket 6 is mounted on the frame 2 of the roof window 1, and the second engagement means 629 is configured to be received in another receiving structure of the outer side of the frame member 22 only in its active position when the mounting bracket 6 is mounted on the frame 2 of the roof window 1. Figure 4 As best shown in FIG, the first engaging means 624 is received in the first outer groove 27 and the second engaging means 629 is received in the second outer groove 27b. At least the side frame members 22, 23 each include a plurality of receiving structures at the outer side of the respective side frame member, so that at least one of the receiving structures interacts with the mounting bracket 6 when the roof window 1 is installed. The first outer groove 27 and the second outer groove 27b both extend in the longitudinal direction of the side frame member 22 at a distance from each other in the height direction, with the first outer groove 27 positioned outside the second outer groove 27b as viewed in the height direction.

[0076] The second part 626 and the second engaging device 629 are brought from a position in the opening 620 in the second bracket leg 62 to a position where the second part 626 is roughly positioned at an extension of the first part 621, and the second part 626 and the second engaging device 629 are connected to the first part 621 via a hinged connection 625, so that the second part 626 is configured to be brought from an inactive position to an active position by rotating the second part 626.

[0077] In the embodiment shown, each of the first and second engagement means comprises a flange 624, 629 projecting at substantially right angles from the respective first and second parts 621, 626. Alternative configurations, such as discrete spikes, are also conceivable.

[0078] Articulated assemblies and joint units- Figures 6 and 7 as well as Figure 22 and Figure 23

[0079] First refer to Figure 6 and Figure 7 , which shows that the roof window 1 further comprises a hinge assembly 9 .

[0080] The hinge assembly 9 is configured so as to allow the sash 3 to be top-hung in a first operating state corresponding to normal use. That is, during normal use, the sash 3 rotates about a first, generally horizontal hinge axis α at or near the top frame member 21 and the top sash member 31 between a closed position and an open position.

[0081] Now also refer to Figure 22 and Figure 23 It can be seen that the hinge assembly 9 includes a hinge unit 91, which has a frame hinge part 92 connected or capable of being connected to at least the top frame member 21, a window frame hinge part 93 connected to at least the top window frame member 31, and a hinge pin 94 connecting the frame hinge part 92 with the window frame hinge part 93.

[0082] The term "connected to" means that the component in question is in a condition, state or position in which the component in question is actually connected to a part, while "connectable to" is intended to include conditions, states and positions in which the component in question can be connected to the relevant part but is not necessarily connected to that part. Figure 22 and Figure 23 In the description, the frame hinge portion 92 including any subcomponents will be described as being connected to the frame 2.

[0083] Hereinafter, the coupling unit 95 of the hinge assembly 9 will be described in considerable detail. The details of the hinge assembly 9 are described in greater detail in the applicant's co-pending patent application filed on the same date as the present application.

[0084] The coupling unit 95 is configured to allow at least the frame hinge portion 92 of the hinge unit 91 to be selectively coupled to the top frame member 21 and, optionally, to one of the side frame members 22, 23. Hereinafter, the coupling unit 95 will be described as including both the top frame coupling plate 96 and the side frame coupling plate 97. Alternative configurations are contemplated.

[0085] The top frame coupling plate 96 includes a base portion 961 that is connected to the inner side of the top frame member 21. The top frame coupling plate 96 is connected to the top frame member 21 by means of a plurality of fastening means, including at least one peg 961c on the base portion 961 and two bolt elements that also serve as engagement pins 962, 963. In this case, each engagement pin 962, 963 mates with an insert nut 982, 983 on the outer side of the top frame member 21. To accommodate the top frame coupling plate 96, the top frame member 21 includes a hinge assembly receiving knurled edge 29a and a set of openings 29c, 29e, wherein the opening 29e is a through-opening or through-hole.

[0086] The side frame coupling plate 97 includes a base portion 971 and is connected to the inner side of the side frame member 22 by means of a plurality of fastening means, including at least one peg 971e on the base portion 971 and at least one opening (not shown in detail) for a fastening means, such as a screw 981. To receive the side frame coupling plate 97, the side frame member 22 includes a hinge assembly receiving knurled edge 29b and a set of openings 29d, 29f.

[0087] Operational Components- Figure 8 and Figure 10

[0088] During normal use, i.e. when the roof window 1 has been installed and the user wishes to place the sash 3 in the ventilation position, opening, closing and stopping can be achieved with the aid of an operating assembly, such as a manual winder or screw jack constituting the operating assembly 5 as shown.

[0089] First refer to Figure 8 The operating assembly 5 includes a window frame accessory 55, a main shaft portion 52 having a main shaft 521, and a handle 522. The main shaft 521 is connected to the sleeve accessory 51 via a nut portion 53. In the installed state of the operating assembly, the window frame accessory 55 is connected to the bottom window frame member 34 and the sleeve accessory 51 is connected to the bottom frame member 24, so that when the main shaft portion 52 rotates relative to the nut portion 53, the bottom window frame member 34 moves relative to the bottom frame member 24.

[0090] In the illustrated embodiment, the roof window 1 can be provided in a supply state suitable for packaging and shipping, with the window frame fitting 55 connected to the bottom window frame member 34 of the roof window 1, while the main shaft part 52 and the nut part 53 and the socket fitting 51 are provided separately from the roof window 1.

[0091] The nut portion 53 comprises a nut ring 531 which is connected here to a set of flanges 512 projecting from a base plate 511 of the socket fitting 51 by means of a set of bolts 532. Apertures 513 are provided in the base plate 511 for mounting the socket portion 51 to the bottom frame member 24.

[0092] The operating assembly 5 also includes a split 56 associated with the window frame fitting 55, which is capable of shifting between an active position in which it engages with a set of openings 553 in a set of flanges 552 protruding from a base plate 551 of the window frame fitting 55, and an inactive position in which it displays a receiving gap between the flanges 552 of the window frame fitting 55.

[0093] The main shaft portion 52 includes an end portion 54 configured to cooperate with a window frame fitting 55 in an installed state.

[0094] Window frames and frame structures- Figures 5 to 16

[0095] like Figure 8 and Figure 9 As shown in the cross-sectional view of the bottom part of the roof window 1 in FIG, the pane 4 comprises an outer sheet 41 and at least one inner sheet, where two inner sheets 42, 43 are placed in contact with each other. The pane 4 is a so-called stepped pane, wherein the outer sheet 41 comprises an extension portion 41a extending beyond the bottom edge portion 42b of the inner sheets 42, 43 to the bottom edge portion 41b of the outer sheet 41. Now also with reference to Figure 4 and Figure 5 , showing the side and top parts of the roof window 1 respectively, the panes 4 have a common side edge portion 4b and a common top edge portion 4c, which also applies to the opposite, not shown side. Spacers 47 are provided between the outermost inner sheet 42 and the outer sheet 41 along all edge portions.

[0096] All the window frame parts 31, 32, 33, 34 of the window frame 3 according to the present invention have in common that each window frame member comprises: a profile element 31a, 32a, 34a, an inner element 31c, 32c, 34c and an intermediate element 31b, 32b, 34b. Although not indicated, the side window frame member 33 not shown in cross section has a similar configuration to the side window frame member 32 shown.

[0097] The intermediate elements 31b, 32b, 34b of the respective window frame members 31, 32, 33, 34 form the connection between the profile elements 31a, 32a, 34a and the inner elements 31c, 32c, 34c of the window frame members 31, 32, 33, 34 in question. The intermediate elements 31b, 32b, 34b of the window frame members 31, 32, 33, 34 can, in principle, be formed in the same manner or with separate properties for all four window frame members. However, typically, the two side window frame members 32, 33 of the window frame 3 will be designed to have the same properties.

[0098] Also refer to Figure 12a In the embodiment shown, the intermediate element 31b of the top sash member 31 and the intermediate elements 32b, 33b of the two side sash members 32, 33 are formed as a set of longitudinal profiles, while the intermediate element 34b of the bottom sash member 34 comprises a set of separate fittings, combined Figure 14a -b will be described in more detail. The details of the respective intermediate elements 31b, 32b, 33b, 34b will be described below.

[0099] The interior elements 31c, 32c, 33c, 34c of the window frame members 31, 32, 33, 34 form a continuous interior element window frame structure that supports the interior edge portion of the window pane 4. That is, when viewed from the interior, the edge portion of the window pane 4 partially overlaps with the interior elements 31c, 32c, 33c, 34c. In this manner, the top edge portion 4c, the side edge portion 4b and the opposing side edge portion, as well as the bottom edge portion 42b of the interior sheet 42, are all positioned on the exterior side of the continuous window frame structure provided by the interior elements. Any spacers 47 and other elements present along the edge portion of the window pane 4 are obscured by the interior elements 31c, 32c, 33c, 34c and are therefore not visible from the interior of the building. The interior elements 31c, 32c, 33c, 34c of the window frame members 31, 32, 33, 34 can have substantially the same cross-section and be formed from any suitable material, such as wood joined in mortise and tenon joints at the corners. It is also contemplated to form the internal element structure as a fully coherent structure, for example by molding.

[0100] As will be described in more detail in conjunction with the following embodiments, the profile elements 31a, 32a, 33a, 34a of the window frame members 31, 32, 33, 34 are positioned along the corresponding outer edge portions of the window pane 4, and the intermediate elements 31b, 32b, 33b, 34b of each window frame member 31, 32, 33, 34 include joining devices 32b3, 34b3, which are configured to form a structural connection with the inner element 32c, 34c at one of at least two different positions in the height direction.

[0101] Figure 5 and Figure 6 Also indicated are hinge assemblies 9 present in the gap between the top sash member 31 and the top frame member 21 , and in the gap between the side sash members 32 and the side frame members 22 , by which the sash 3 is connected to the frame 2 to provide a top-hung hinged connection.

[0102] With respect to the frame 2 of the roof window 1, each frame member 21, 22, 23, 24 comprises a plurality of receiving structures located inside, outside, inside and / or outside the corresponding frame member. Each receiving structure is configured to interact with auxiliary equipment in the assembled state of the frame 2.

[0103] In the embodiment shown, the top frame member 21 and the two side frame members 22, 23 have substantially the same cross-section.

[0104] With particular reference Figure 8 and Figure 9 The bottom frame member 24 includes an outer panel 24a and a separate inner panel 24b. The outer panel 24a and the separate inner panel 24b can be formed from the same material as the top frame member 21 and the side frame members 22, 23, such as wood, or as a composite component including plywood and other materials.

[0105] Another feature of the roof window 1 in the embodiment shown is that the frame 2 comprises at least one releasable component configured to allow replacement with a different set of components in order to change the functionality of the roof window 1 .

[0106] In the illustrated embodiment, one such releasable component includes a cover 24c that is releasably connected to and defines a cavity relative to the remainder of the base frame member 24. The cover 24c may be formed from any suitable material, such as a profile member of a plastic or metal material.

[0107] Here, the bottom frame member 24 includes an outer panel 24a and a separate inner panel 24b, and the cavity defined by the cover 24c is defined outwardly by the inner side of the outer panel 24a and mainly inwardly by the outer side of the separate inner panel 24b.

[0108] To obtain a releasable connection, edge portions 24c1 , 24c2 of cover 24c are received in receiving recesses in bottom frame member 24, in particular one receiving recess 24a1 in outer panel 24a and a separate receiving recess 24b1 in inner panel 24b.

[0109] In the embodiment shown, in which the roof window 1 is provided for manual operation by means of the operating assembly 5 , the thermal insulation 24 d is housed in a cavity defined by the cover 24 c .

[0110] To change the function of the roof window 1 , the cavity defined by the cover 24 c is configured to receive an electric operator (not shown), and the cover 24 c is configured to be replaced by a different cover (not shown) allowing the operating device of the electric operator to be connected to the window frame 3 .

[0111] It is also contemplated to allow the sash fitting 55 connected to the bottom sash member 34 to be selectively connected to such an electrical operator, in which case the sash fitting 55 simply duplicates the operating means for the electrical operator.

[0112] Likewise, it is envisaged that the roof window 1 is provided where the bottom frame member 24 comprises a dummy element configured to be replaced by the socket fitting 51 of the operating assembly 5 .

[0113] Accordingly, if the roof window 1 is provided in the basic form of a hinge different from the hinge assembly 9 described in the above embodiment, it is also envisaged to use a blind plate to cover the hinge assembly receiving knurled edges 29a, 29b to allow the hinge assembly 9 to replace the previous hinge.

[0114] The first receiving structure includes a lining groove 25 on the inside of each frame member 21, 22, 23, 24. The lining groove 25 is configured to interact with a set of interior lining panels. Such lining panels typically form a transition between the roof window 1 and the interior wall. In the bottom frame member 24, a first groove portion 25a is provided in the outer panel 24a, and a second groove portion 25b is provided in the separate inner panel 24b. In the assembled state of the frame 2, the first groove portion 25a and the second groove portion 25b form the lining groove 25.

[0115] In the embodiment shown, each frame member 21, 22, 23, 24 includes, when viewed from the inside, an inwardly projecting portion 21i, 22i, 24i that at least partially overlaps the corresponding sash member 31, 32, 33, 34. This is possible because all parts of the sash 3 move toward the outside when the sash 3 is opened relative to the frame 2.

[0116] The second receiving structure comprises a sealing groove 26 located outside the inwardly projecting portions 21i, 22i, 24i. The sealing groove 26 is configured to interact with a frame sealing profile 26p.

[0117] The third receiving structure comprises a first outer groove 27 located on the outer side of the frame members 21, 22, 23, 24. The first outer groove 27 is configured to interact with the corresponding plate 71, 72, 73, 74 of the insulation frame 7. The interaction can occur by introducing the longitudinal protrusion 78 of the insulation frame plate into the groove 27, or by correctly positioning a separate fastening device.

[0118] Again, from the user's perspective as seen from the interior of the building, with the roof window 1 mounted on the roof, it is also noted that the inwardly projecting portions 21i, 22i, 24i of each frame member 21, 22, 23, 24 have inwardly facing surfaces that together form a continuous inwardly facing surface. As noted, this appearance mimics the corresponding continuous inwardly facing surface of the window frame 3.

[0119] The fourth receiving structure includes an engagement unit groove 28 located on the outside of the top frame member 21 and the outside of the two side frame members 22, 23. The engagement unit groove 28 interacts with the corresponding top element 81 and side elements 82, 83 of the engagement unit 8, and the function of the engagement unit groove 28 will be further described below.

[0120] Other details visible in the drawings include guide elements 22g (see Figure 7 ) and guide element 32g (see Figure 10 ), the guide elements 22g and 32g determine that the sash 3 is aligned relative to the frame 2 when the sash is closed so that any skew that occurs in the open position of the sash 3 is eliminated. Figure 8 As can be seen in the figure, an internal shading device (not shown) can be mounted in the sash 3 by means of a shading mounting bracket to provide shading to the pane 4. The abutment element 22s provides a stop for the bottom sash member 34 during closing.

[0121] Also shown in these figures are details of the insulating frame 7; as mentioned above, the insulating frame 7 comprises a top panel 71, side panels 72, 73 and a bottom panel 74. In the embodiment shown, each such insulating frame panel comprises a projection 78 to be received in the outer side of the corresponding frame member and an indentation 75 for interacting with auxiliary equipment in the form of an under-roof sleeve described in more detail in the applicant's co-pending patent application filed on the same date as the present application. With particular reference to Figure 11 , showing recesses 76 for mounting brackets 6 to be mounted on side frame members 23 of frame 2, and fold lines 77 that allow a portion of side panels 73 of insulating frame 7 to be folded back to access the outside of side frame members 23. At least side panels 72, 73 of insulating frame 7 are provided with such recesses 76 and fold lines 77 at or near the intended locations of mounting brackets 6 of a set of mounting brackets for roof windows 1. In principle, insulating frame 1 can be made of any material with suitable insulating properties. Currently, the use of foam materials, such as polyethylene foam, is preferred.

[0122] Intermediate components- Figures 5 to 16

[0123] Referring now to the description of the connections between the elements of the sash 3, first the engagement between the intermediate elements 31b, 32b and 33b of the top sash member 31 and the two side sash members 32, 33 and the respective inner elements 31c, 32c, 33c will be described.

[0124] With particular reference Figure 16 The outer side of each inner element, here shown as the inner element 32 c of the side sash member 32 , is provided with receiving means configured to receive the engaging means of the intermediate element 32 b of the side sash member 32 .

[0125] In the embodiment shown, the receiving means comprise two longitudinally extending grooves 32c1 , 32c2 at a distance from one another in height direction, which grooves open in outward direction of the roof window 1 .

[0126] In the embodiment shown, the longitudinal profiles forming the intermediate elements 31b, 32b, 33b have a uniform cross-section and can, in principle, be cut from one and the same profile length. Preferably, the longitudinal profiles are formed by a continuous molding process, such as extrusion or pultrusion. In particular, the profiles are formed by pultrusion of a composite material combining resin and glass fibers.

[0127] Therefore, only one of these intermediate elements, namely intermediate element 32b, will be described in detail. Figure 15 The intermediate element 32b includes a base portion 32b1 extending substantially in the height direction in the assembled state of the window frame 3 and a head portion 32b2 extending at an angle to the base portion 32b1. Figure 16 As shown in FIG, the base portion 32b1 is provided with engagement means on an inwardly facing surface in the assembled state, which surface faces the outer surface of the inner element 32c. Figure 3 、 Figure 4 、 Figure 5 、 Figure 10 and Figure 12a The position, location and length of the individual intermediate elements 31b, 32b and 33b are also presented.

[0128] In the embodiment shown, the engagement means of the base portion 32b1 of the intermediate element 32b comprise a protruding portion formed as a flange 32b3 extending over the entire length of the profile and configured to engage with a selective one of the grooves 32c1 , 32c2 of the inner element 32c of the side sash element 32 .

[0129] The base portion 32b1 of each intermediate element 32b comprises a stepped portion 32b4 offset in an inward direction relative to the remainder of the base portion 32b1 by an offset bend 32b5. Engaging means, here a flange 32b3, are provided in the stepped portion 32b4.

[0130] Provide additional fastening means 30x (see Figure 12a and Figure 16 ) to fasten the intermediate element 32b to the inner element 32c of the side sash member 32. To receive the additional fastening device 30x, the base portion 32b1 of the intermediate element 32b includes an opening 32b6 configured to receive the additional fastening device 30x, ie, the opening 32b6 is in the stepped portion 32b4.

[0131] Now with particular reference Figure 14a and Figure 14b , the connection between the middle element 34b and the inner element 34c of the bottom sash member 34 will be described in detail.

[0132] As with the intermediate elements 31b, 32b, and 33b described above, the intermediate element 34b includes a base portion 34b1 extending generally in the height direction and a head portion 34b2 extending at an angle relative to the base portion 34b1. The base portion 34b1 is provided with an engagement feature 34b3 on its inner surface, which faces the outer surface of the inner element 34c. The engagement feature of the base portion 34b1 includes a protrusion 34b3 that engages with one of the grooves 34c1 and 34c2 of the inner element 34c of the bottom sash member 34. Additional fastening features 30y are provided in an opening 34b6 in a stepped portion 34b4, offset inwardly from the remainder of the base portion 34b1 by an offset bend 34b5, to secure the intermediate element 34b of the bottom sash member 34 to the inner element 34c.

[0133] In the embodiment shown, the intermediate element 34b of the bottom sash member 34 comprises a set of fittings. Two such sets may be provided along the length of the bottom sash member 34.

[0134] Each set of fittings includes a connecting fitting equipped with an engagement mechanism configured to form a structural connection with the inner element 34c in one of at least two different positions in the height direction. The connecting fitting comprises a first fitting portion 34b0 and a second fitting portion 34b10. The first fitting portion 34b0 includes the engagement mechanism, and the second fitting portion 34b10 is configured to connect to the first fitting portion 34b0 to serve as a spacer between the outer surface of the inner element 34c of the bottom sash member 34 and the first fitting portion 34b0. To connect the first and second fitting portions 34b0, 34b10, the second fitting portion 34b10 is equipped with at least one resilient hook 34b11 configured to interact with a corresponding opening 34b12 in the first fitting portion 34b0. When the window frame 3 is assembled, the head portion 34b2 of the intermediate element 34b of the bottom sash member 34 is received in the slit 34a5 of the inner portion 34a2 of the profile element 34a of the bottom sash member 34.

[0135] Comparative Implementation Methods- Figure 17 and Figure 18

[0136] Reference is now made to a simplified diagram showing the main components of the side sash member 32. Figure 17 and Figure 18 , you can see how the same part of the window frame 3 can accommodate two panes 4 of different thicknesses. This is achieved by changing the position of the engagement means of the intermediate element 32b from the first groove 32c1 to the second groove 32c2. This will require a slight adaptation of the side frame member 22c. The intermediate elements 31b, 33b, 34b of the other window frame members 31, 33, 34 are similarly moved.

[0137] Profile components- Figures 19 to 21

[0138] The focus will now be on the profile elements of the window frame 3. Figures 3 to 6 and Figure 10 The perspective view shows the overall configuration of the profile element 31a of the top window frame member 31 and the profile elements 32a, 33a of the side window frame members 32, 33, while in Figure 16 Details are shown in the cross-sectional view of Figures 12a to 14b The profile element 34a of the bottom sash member 34 is shown most clearly in FIG.

[0139] Corresponding to the above, only the profile element 32a of the side sash member 32 will be described to represent the longitudinal profiles of the top sash member 31 and the longitudinal profiles of the two side sash members 32, 33, since in the embodiment shown these profile elements are formed as a set of longitudinal profiles having a substantially uniform cross section.

[0140] The common details of all profile elements 31a, 32a, 33a, 34a are as follows:

[0141] Each profile element 32a, 34a comprises a head portion 32a1, 34a1 and an adjoining outer portion 32a3, 34a3.

[0142] The head portion 32a1 , 34a1 is approximately parallel to the plane of the roof window 1 in the assembled state of the roof window 1 , whereas the adjoining outer portion 32a3 , 34a3 is approximately perpendicular to the head portion 32a1 , 34a1 .

[0143] However, the head portion 32a1 of the profile element 32a of each of the top sash member 31 and the side sash members 32, 33 is positioned on the outer side of the outer pane surface 4e of the window pane 4 and the outer side edge portions 4b and the top edge portion 4c of the window pane 4, while the head portion 34a1 of the profile element 34a of the bottom sash member 34 is positioned on the inner side of the extension portion 41a of the outer sheet 41 of the window pane 4.

[0144] The profile element 32a of the side sash member 32 and the profile element 34a of the bottom sash member 34 are thus separated by a layer of glass; however, an overlap is provided by selecting the length of the profile elements 32a, 33a of the two side sash members 32, 33 to correspond approximately to or slightly exceed the distance between the top edge portion 4c of the window pane 4 and the bottom edge portion 41b of the outer sheet 41 of the window pane 4. The length of the profile element 34a of the bottom sash member 34 is suitably selected to extend approximately to the side edge portion 4b of the window pane 4.

[0145] The length of the profile element 31a of the top window frame member 31 is selected according to the size of the window pane 4 and the desired way of connecting the profile element 31a to the profile elements 32a, 33a. Figure 19 In the assembled state of the window frame 3 , the longitudinal profiles form a mitered joint between the profile element 31 a of the top sash member 31 and the corresponding profile elements 32 a , 33 a of the side sash members 32 , 33 .

[0146] exist Figures 12a to 13b Also visible is an end plug 38 that blocks the profile element 32a of the side sash member 32. The end plug 38 is provided with friction-increasing ribs and snap-on arms, not described in detail. The glass spacer 45 is provided with a corresponding end plug. Furthermore, a trailing element 37 is provided to drain any condensed water to the profile element seal 34p.

[0147] See Figures 19 to 21 To ensure a tight connection at the miter joint, an angle key 39 is provided at each miter joint. Figures 19 to 21 The sealant 39b is suitably applied as described in further detail.

[0148] The angle key 39 generally has an L-shaped configuration with two vertical legs 39a1 separated by a channel 39a2. In the channel 39a2, a set of main openings 39a3 are provided.

[0149] Furthermore, each leg 39a1 adjoins on a first side a depending skirt 39a4, wherein a secondary opening 39a5 is provided.

[0150] For fitting the profile of the profile elements 31a, 32a, 33a, each leg 39a1 adjoins on a second side an inclined portion 39a6.

[0151] like Figure 20 and Figure 21 As shown in FIG, the channel 39a2 ends in a tongue 39a7, optionally adjoined by an inclined channel portion 39a8.

[0152] The profile elements 31a, 32a, 33a are suitably configured to receive the pane 4 in an inverted position, i.e. in which the respective head portion 32a1 faces a base plate such as an assembly table. This step of assembling the window frame 3 can be carried out after the intermediate elements 31b, 32b, 33b have been introduced into the respective profile elements 31a, 32a, 33a. Figure 16 and Figure 19 Also visible are pane holders 4t placed at a suitable distance from each other along the top edge portion 4c and the side edge portion 4b of the pane 4. In the embodiment shown, the interaction between the main components of the window frame 3 is defined by the following configuration of components:

[0153] Each of the longitudinal profiles forming the profile element 31a of the top sash member 31 and the profile elements 32a, 33a of the two side sash members 32, 33 comprises an inner portion 32a2 adjoining the head portion 32a1. The dimensions are selected so that the inner portion 32a2 overlaps the window pane 4 in the assembled state of the sash 3.

[0154] The head portion 32a1 of each profile element 31a, 32a, 33a is configured to project to the outside relative to the outer surface 4e of the pane in the assembled state of the window frame 3.

[0155] In the assembled state of the window frame 3, the inner portion 32a2 is inclined from the head portion 32a1 relative to the head portion 32a1 and extends inwardly towards the outer surface 4e of the window pane and extends to the inside.

[0156] The inner portion 32a2 is adjacent to a first bend 32a4 that is configured to be positioned at or near the outer surface 4e of the pane.

[0157] The second bent portion 32a5 is provided as, for example Figure 16The second bend 32a5 has the function of housing the seal 4p relative to the outer surface 4e of the pane.

[0158] A third bend 32a6 is also provided, which is configured to accommodate an inner edge portion 32b9 of the intermediate element 32b relative to the inner side of the inner portion 32a2. For a detailed schematic view of the intermediate element 32b, refer to Figure 15 .

[0159] A transition portion 32a7 is provided between the head portion 32a1 and the inner portion 32a2. The transition portion 32a7 is configured to receive the ridge portion 32b7 of the intermediate element 32b.

[0160] Adjacent to the outer portion 32a3 of the profile element 32a a fourth bend 32a8 is provided. The fourth bend 32a8 is configured to receive an outer edge portion 32b12 of the intermediate element 32b.

[0161] In the assembled state of the window frame 3 , the inner portion 32 a 2 of the profile element 32 a is configured to be positioned opposite the inner inclined portion 32 b 8 of the intermediate element 32 b .

[0162] Finally, the outer edge portion 32b12 of the intermediate element 32b is associated with the head portion 32b2 of the intermediate element 32b via an outer inclined portion 32b11 and a bend 32b10.

[0163] All in all, the configuration of the described embodiment makes it possible to provide a secure joint between the intermediate elements 31 b , 32 b , 33 b and the profile elements 31 a , 32 a , 33 a .

[0164] The length of the intermediate elements 32b, 33b of the side sash members 32, 33 may be chosen to be slightly shorter than the associated profile elements 32a, 33a.

[0165] At the bottom sash member 34, the head portion 34a1 of the profile element 34a is provided with at least one longitudinally extending groove 34a4 for receiving a corresponding sealing strip 4s. These sealing strips 4s may be made of silicone to form an adhesive bond between the profile element 34a and the extension 41a of the outer sheet 41 of the window pane 4. A mask 44 may be provided on the inner side of the extension 41a of the outer sheet 41.

[0166] As described above, the intermediate element 31b, 32b, 33b, 34b of each window frame member 31, 32, 33, 34 includes a joining device 32b3, 34b3 configured to form a structural connection with the inner element 31c, 32c, 33c, 34c. Figures 14a to 14bIn order to further secure the intermediate element 34b of the bottom sash member 34 to the profile element 34a, the head portion 34b2 of the intermediate element 34b is configured to be received in the slit 34a5 of the inner portion 34a2 of the profile element 34a of the bottom sash member 34 in the assembled state of the window frame 3. To increase the strength of the inner portion 34a2, the portion may be formed as a two-layer folded portion.

[0167] The manufacture of the window frame 3 can in principle be carried out in any suitable manner. In the following, a currently preferred method will be described:

[0168] In a first step, a set of three longitudinal profiles is provided. For example, the longitudinal profiles can form a single profile length of extruded material, such as a metal such as aluminum. Other materials and manufacturing processes are contemplated, including roll forming of steel or other metals or roll forming of composite materials.

[0169] Secondly, a mitered shape is formed at the mutually facing ends of the longitudinal profile.If the longitudinal profile consists of a single length, and if convenient, the mitered shape can be formed in a continuous length by appropriately formed cuts forming internal corners at the intersection between the top and the side.

[0170] Set up the panes to the appropriate size, for example as described above.

[0171] A set of four inner elements and four intermediate elements is provided, for example as described above.

[0172] The longitudinal profiles are now placed in an inverted position on an assembly table to form a profile element frame structure forming three sides of a rectangle. This is usually achieved by guide elements that can be fixed to the assembly table corresponding to the periphery of the window frame.

[0173] The window pane is placed within a profile element frame structure, which is then optionally connected to the inner elements via intermediate elements to form a window frame. During this process, the intermediate elements at the top and sides are typically inserted into the corresponding profile elements. Multiple inner elements can be interconnected as described above to form an inner element frame structure that is placed on the window pane. Subsequently, the intermediate elements are connected to the corresponding inner elements.

[0174] Brief reference back Figures 19 to 21 Before the pane 4 is placed in the profile element frame structure, a set of two corner keys 39 is advantageously provided, placed in the longitudinal profile elements 31a, 32a, 33a at the mutually facing mitered ends. A sealant 39b is preferably applied to each corner key 39. During assembly, it is ensured that the sealant 39b can flow through the main openings 39a3 of the corner keys 39 so that the sealant 39b is distributed.

[0175] In the embodiment shown, each angle key 39 is configured to be mechanically connected to the corresponding adjacent profile element 31a, 32a, 33a. This can be done by nailing, for example by Technology to achieve.

[0176] In the embodiment where the roof window 1 comprises one or more glass spacers, such as the glass spacer 45, the glass spacers are aligned on the assembly table before the pane 4 is placed in the profile element frame structure. The glass spacer 45 is provided with one or more adhesive strips 45a fastened to the outer surface 4e of the pane 4.

[0177] Sealing assemblies and joint units- Figures 24 to 36

[0178] Now with particular reference Figures 24 to 29a , shows an embodiment in which a roof window 1 is provided with a cover assembly 10. Details of the cover assembly 10 generally including a flashing assembly and any other auxiliary equipment are described in more detail in the applicant's co-pending patent application filed on the same day as the present application.

[0179] Hereinafter, the sealing assembly of the roof window 1 will be described. Some details of the sealing assembly have also been described above.

[0180] A sealing assembly typically comprises a set of sealing profiles.

[0181] In the embodiment shown, the seal between the sash 3 and the frame 2 is provided by an outer sealing plane, an intermediate sealing plane and an inner sealing plane.Reference is also made to the top, side and bottom cross-sectional views of the roof window 1 shown and described above.

[0182] The inner sealing plane comprises a frame sealing profile 26 p provided on the outer side of each frame member 21 , 22 , 23 , 24 and interacting with the inner side of the corresponding window frame member 31 , 32 , 33 , 34 .

[0183] The intermediate sealing plane comprises a sash sealing profile 30p1 provided on the outer side of each sash member 31, 32, 33, 34 and interacting with the inner side of the corresponding frame member 21, 22, 23, 24. The sash sealing profile 30p1 is provided in a sash sealing groove 30g1.

[0184] On the bottom side, in the closed position of the sash 3 , an outer sealing plane is provided because the profile element seal 34 p on the profile element 34 a of the bottom sash member 34 is in contact with the outer side of the bottom frame member 34 .

[0185] At the top and sides, the outer sealing planes are defined by the joining elements 81, 82, 83. With particular reference to Figure 26 and Figure 27, the similarities and differences between the top engaging element 81 and the side engaging elements, represented here by engaging element 82, of the illustrated embodiment will be described:

[0186] Each engaging element 81, 82 comprises a base portion 80 having an anchoring portion 801, an inner leg 86, an outer leg 87, a flange 88 and a sealing portion 89. The anchoring portion 801 of the base portion 80 is received in the engaging unit groove 28 in the assembled state of the roof window 1. The sealing portion 89 faces outward and interacts with the top sash member 31 and the side sash members 32, 33 during opening and closing of the sash 3 and in the closed position of the sash 3.

[0187] The inner leg 86, the outer leg 87, and the flange 88 together form a channel 810 in the top engaging element 81 and a channel 820 in the side engaging element 82. A corresponding channel is formed in the other side engaging element 83. In this way, water from rain or other precipitation can be directed from the channel 810 in the top engaging element 81 to the channels 820 in the side engaging elements 82, 83 and further outwardly to the cover assembly 10 (not shown in detail).

[0188] Common to both the top engaging element 81 and the side engaging element 82 in the illustrated embodiment is that the sealing portion 89 includes an inner sealing lip 891 and an outer sealing lip 892. Figure 6 and Figure 5 , the inner sealing lips 891 of both the top engaging element 81 and the side engaging element 82 are positioned sufficiently inwardly so that the inner sealing lips 891 interact with the interior of the top sash member 31 and the side sash member 32; however, the outer sealing lip 892 of the top engaging element 81 is positioned on the outer side of the top sash member 31. In the illustrated embodiment, this is due to the fact that the flange 88 of the top engaging element 81 is longer than the corresponding flange of the side engaging element 82. Note that although at least the sealing portion 89 of each engaging element 81, 82, 83 is formed to be elastic, i.e., as is typical of seals, the sealing portion 89 is able to deform when abutting another component and then rebound when released, this is not reflected in the figures, as the figures generally show the elements in their undeformed state. Typically, at least the sealing portion 89 has different properties than at least the base portion 80. This can be achieved by coextrusion or comolding of two (or more) different materials.

[0189] To ensure tight interaction at the top of the roof window 1, also refer to Figure 28 , the top joining element 81 includes an additional inner sealing lip 893 , a first additional outer sealing lip 894 and a second additional outer sealing lip 895 .

[0190] In the embodiment shown, engagement elements 81, 82, 83 also allow for interaction with cover assembly 10 because base portion 80, inner legs 86 and flange 88 form flashing receiving groove 85. Flashing receiving groove 85 has a groove opening 85b and is provided with a plurality of protrusions 85a.

[0191] The sealing assembly further comprises a pane seal 30p2 received in the pane sealing groove 30g2. Note that the pane seal 30p2 remains fixed relative to the window frame 3.

[0192] Now refer to Figures 29b to 36 , details of an alternative embodiment will be described. Only the differences from the above-described embodiment will be described in detail.

[0193] exist Figure 29b , a foam element 32f is shown present in the side sash member 32. A similar foam element may also be present in the opposing side sash member 33. The longitudinal extension of the foam element 32f may be such that the foam element 32f extends over a substantial portion of the length of the side sash member 32. The foam element 32f abuts the inner side of the head portion 32b2 of the intermediate element 32b along the length of the intermediate element 32b, and is allowed to expand toward the inner side of the head portion 32a1 of the profile element 32a of the side sash member 32 at the portion of the foam element 32f that protrudes beyond the longitudinal end of the intermediate element 32b. The foam element 32f has generally weatherproof properties.

[0194] exist Figure 30 In the embodiment, the stabilizing plate 310x is placed in the channel 810 of the top element 81 of the joint unit 8 to improve the structural properties. In addition, the extension plate 310y is shown as being fastened to the profile element 31a of the top window frame member 31 so as to protrude into the channel 810. The extension plate 310y improves the guidance of precipitation into the channel 810 and serves to guide it further towards the sides of the roof window. This is particularly relevant in relation to roof windows built in roofs with steep slopes. Figure 32 The relative positions of the stabilizing plate 310x and the extension plate 310y are more clearly shown in FIG. Figure 33 The top element 81 of the joining unit 8 is shown without the stabilizing plate 310x and the window frame 3 including the extension plate 310y.
