Description

Technical Field

[0001] The present invention relates to a roof window, which comprises a frame, a window frame and a window pane. In the roof window, the frame comprises a set of frame members, the set of frame members including a top frame member, two side frame members and a bottom frame member, and the window frame comprises a set of window frame members, the set of window frame members including 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 the inclined roof surface. When selecting a type of roof window for a specific installation position in a building, parameters such as operability, thermal performance, weather resistance and proper decoration of the building interior are usually given substantial weight; however, it is generally desirable and in some areas actually necessary to consider the external appearance. This is especially applicable to the installation of roof windows in protected areas, where building regulations may require the roof windows to meet standards or local requirements. Therefore, certain requirements apply depending on whether the installation involves newly installed roof windows or replacing existing windows or skylights as part of a renovation or refurbishment project.

[0003] Past windows or skylights were usually made of cast iron and individual glass pane members, separated by one or more cast iron glass dividers, and the thermal efficiency of these roof windows or skylights left room for improvement. To meet the energy consumption performance required by modern building regulations, energy-saving roof windows are usually provided with insulating panes while starting to imitate the style of traditional skylights.

[0004] In many installation cases, it is also required that energy-saving roof windows can be installed with a "low profile", that is, the height of the part of the roof window protruding above the surrounding roof is as small as possible. This is particularly evident in buildings with a generally flat roof material such as slate or shingles. To meet this requirement, most major roof window manufacturers allow installation in at least two layers to accommodate the height and installation conditions of various roof profiles.

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

[0006] Considering all of the above requirements, for protection purposes, improving the roof window is an ongoing task. Summary of the Invention

[0007] Based on this background, the object of the present invention is to provide a roof window through which the manufacturing, assembly and installation processes become more flexible, and at the same time, the roof window provides sufficient protection against the weather during use.

[0008] This object and other objects are achieved by a roof window of the type mentioned in the introduction, which is further characterized in that a joining unit is provided for interacting with auxiliary devices and / or other components of the roof window in the assembled state of the frame.

[0009] The provision of a single joining unit ensures proper interaction with auxiliary devices, such as sealing profiles and covers, in a simple manner. Manufacturing, assembly and installation can be carried out safely. Other components that meet the conditions for interacting with the joining unit include window frames. This is particularly important when the joining unit has a sealing function.

[0010] In the presently preferred embodiment, the joining unit includes a top joining element and two side joining elements configured to be received in a receiving structure, which includes joining unit grooves in the outer portions of the top frame member and the two side members. In this way, the joining elements can be easily fastened to the frame and thus a central function towards the window frame and, for example, the surrounding cover assembly is obtained. Thus, the joining elements provide a coherent structure along the top and sides in the form of a football goal.

[0011] In a further refinement of this preferred embodiment, each joining element includes a base portion having an anchoring portion configured to be received in the joining unit grooves in the outer portions of the top frame member and the two side members. By dividing the joining unit into different functional parts including the base portion, different properties can be assigned to the different parts. For example, fastening the joining elements will require different performances and thus the performance of the anchoring portion can be customized so that proper retention is achieved.

[0012] In the presently preferred embodiment, the joining unit forms part of an external sealing plane relative to the window frame. By this design, additional protection against the weather is provided, since the external sealing plane provides a first protection against weather including rain and other precipitation, wind, sound, etc. In order to protect the inevitable gap between the frame and the window frame, an intermediate sealing plane and an internal sealing plane provide additional security.

[0013] Preferably, the external sealing plane is provided by the joining elements at the top frame member and the top window frame member and at the side frame members and the side window frame members. In this way, important weatherproofing performance is obtained at the positions where the window frame and the frame are adjacent in the closed position of the window frame.

[0014] Each joining element preferably includes an inner leg and an outer leg, a flange and a sealing portion, the inner leg and the outer leg extending outwards from the base portion. In this way, each joining element is provided with a certain range in both the height and width directions, thus facilitating interaction with other elements.

[0015] In a preferred further improvement, the inner leg, outer leg and flange form channels in the top engaging element and the side engaging element. In this way, the engaging unit provides a guiding channel for rainwater and water generated by other precipitation.

[0016] To further improve the sealing performance, the sealing part includes an inner sealing lip and an outer sealing lip.

[0017] Preferably, the top engaging element includes an additional inner sealing lip, a first additional outer sealing lip and a second additional outer sealing lip. This has been proven to further improve the sealing performance.

[0018] To improve the versatility of the engaging unit, in one embodiment, the base part, inner leg and flange form a waterproof plate receiving groove. This enables the interaction between the roof window and the cover assembly to be provided, and thus provides a weathertight transition to the surrounding roof in a simple and effective manner.

[0019] Each engaging element can be provided as a two-component element, where at least the sealing part has different properties from at least the base part. Since the main function of the base part is to ensure a reliable connection to the frame of the roof window, the base part will generally need to have a harder material property than the sealing part, and the sealing part needs to be elastic and flexible.

[0020] To improve the structural integrity of the engaging unit at the top of the roof window and ensure its proper operation, a stabilizing plate can be placed in the channel of the top engaging element of the engaging unit.

[0021] Although the construction of the window frame member including the profile element itself requires proper water diversion to the surrounding environment, an extension plate can be fastened to the profile element of the top window frame member to project into the channel of the top engaging element of the engaging unit. This ensures that water is properly diverted into the channel of the engaging unit even in roof windows installed on roofs with a large slope.

[0022] Improved retention of the engaging unit can be achieved by a clip mounted on the side engaging element of the engaging unit, the clip being provided with a clip flange to interact with the end plug flange of the end plug of the side window frame member, thereby allowing the end plug flange to overlap the clip flange in the closed position of the roof window.

[0023] Other proposed preferred embodiments and other advantages will be apparent from the following detailed description and the drawings.

[0024] The features described in relation to one aspect can also be incorporated into another aspect, and the advantages of the feature apply to all aspects into which it is incorporated. Description of the Drawings

[0064] In the following detailed description, preferred embodiments of the present invention will be described. However, it should be understood that features of different embodiments can be exchanged 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 some components illustrated in the drawings may be different from the corresponding dimensions in actual implementations.

[0065] It should be noted that terms such as "upper", "lower", "left side", "right side", "outer", "inner", "outside", "inside" are relative and relate to the perspective under discussion. Generally speaking, when referring to the outer side portion, this relates to the side portion of the roof window facing the outside of the building or the outdoors in the installed state. Conversely, the inner side portion relates to the side portion facing the inside of the building, that is, usually the room below including any light well. Terms such as "outward" and "inward" are directions substantially perpendicular to the inside-outside direction, with the center of the roof window as its reference point.

[0066] General description of the roof window- Figure 1 and Figure 2

[0067] First, referring to Figure 1 and Figure 2 , a roof window 1 is shown. The roof window 1 is intended to be installed on an inclined roof surface (not shown).

[0068] The roof window 1 includes a frame 2, a window frame 3, and a window pane 4. The frame 2 includes a set of frame members, and the set of frame members includes a top frame member 21, two side frame members 22, 23, and a bottom frame member 24. Correspondingly, the window frame 3 includes a set of window frame members, and the set of window frame members includes a top window frame member 31, two side window frame members 32, 33, and a bottom window frame member 34. Although the frame 2 and the window frame 3 are described as rectangular structures, some principles of the proposed concept can also be applied to other geometries.

[0069] As will be described in further detail below, the window pane 4 includes a plurality of edge portions that are typically associated with the members of the window frame 3. When in the closed position, the outer window pane surface 4e defines the plane of the roof window 1 in the assembled state of the roof window 1. The assembly condition of the roof window 1 is achieved when the main components of the frame 2 and the window frame 3 have been assembled and the frame 2 and the window frame 3 are connected to each other, for example, when the roof window 1 is in the installation position ready for use. Correspondingly, the assembly condition of the window frame 3 is achieved once the main components of the window frame 3 have been assembled, and the assembly condition of the frame 2 is achieved when the main components of the frame 2 are assembled.

[0070] The inner pane surface 4i faces the interior of the room in the building, usually below the roof surface, in which the roof window 1 is installed. The outer pane surface 4e is equipped with a glass spacer 45, and the inner pane surface 4i is equipped with a glass spacer cover 46. Although not practical, there could also be a two-part pane, where the two panes are divided into two equal parts by a through glass spacer. In a wide roof window, there could also be more than one glass spacer, for example, two glass spacers that divide the surface of the pane visible from the outside into three parts.

[0071] In the illustrated embodiment, the window frame 3 can be opened relative to the frame 2 to obtain one or more open positions. In such an open position, the window frame 3 and the pane 4 are moved out of the plane of the roof window 1. As will be described below, the window frame 3 is shown as top-hung, that is, during normal use, the window frame 3 rotates about a substantially horizontal hinge axis at or near the top frame member 21 and the top window frame member 31. However, it is contemplated that some of the principles of the proposed roof window concept could be applied to different types of windows with other opening methods or provided as fixed skylights.

[0072] Figure 1 and Figure 2 Other details shown include the operating assembly 5, shown here as a manual winder or screw jack. Other operating assemblies could also be present.

[0073] Also shown is a typical mounting bracket 6 that forms part of a plurality of mounting brackets that form a load transfer connection between the roof window 1 and the surrounding roof structure (not shown). Such a roof structure can include rafters and battens, plywood, or other construction materials.

[0074] Finally, a thermal insulation frame 7 is shown. Thermal insulation through the thermal insulation frame is optional and can be provided only along some of the frame members or, as shown, around all four frame members 21, 22, 23, 24.

[0075] In the following description of the various embodiments, elements having the same or similar functions always have the same reference numerals. Appropriate variations and modifications will be apparent to those skilled in the art.

[0076] Mounting bracket and roof window with a set of mounting brackets- Figures 3 to 4

[0077] Generally, a roof window, such as Figure 1 and Figure 2The roof window 1 shown is equipped with a set of mounting brackets 6. As indicated, two mounting brackets 6 are fastened to each side frame member 22, 23. Below, a single mounting bracket 6 associated with one side frame member 22 will be described. The set of mounting brackets 6 will generally be the same, although variations are also possible.

[0078] The mounting bracket 6 includes 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. For this purpose, the second bracket leg 62 includes engagement means that interact with corresponding receiving structures 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 the 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.

[0079] In the illustrated embodiment, the second bracket leg 62 is provided with a first engagement means 624 in a first part 621 of the second bracket leg 62 and a second engagement means 629 in a second part 626 of the second bracket leg 62.

[0080] Of these two engagement means 624, 629, the second engagement means 629 is configured to assume an inactive position and an active position, with the active position shown.

[0081] The first engagement means 624 is configured to be received in one receiving structure on the outer side part of the frame member 22 in the installed state of the mounting bracket 6 on the frame 2 of the roof window 1, and the second engagement means 629 is configured to be received in another receiving structure on the outer side part of the frame member 22 only in its active position in the installed state of the mounting bracket 6 on the frame 2 of the roof window 1. This is most clearly shown in Figure 4 where the first engagement means 624 is received in the first outer groove 27 and the second engagement 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 part of the respective side frame member, such that at least one of the receiving structures interacts with the mounting bracket 6 in the installed state of the roof window 1. Both the first outer groove 27 and the second outer groove 27b extend in the longitudinal direction of the side frame member 22 spaced apart from each other in the height direction, with the first outer groove 27 located outside the second outer groove 27b as seen in the height direction.

[0082] The second part 626 and the second engaging device 629 are brought from their positions in the opening 620 in the second support leg 62 to a position where the second part 626 is generally positioned in the extension of the first part 621. The second part 626 and the second engaging device 629 are connected to the first part 621 via a hinge connection 625 such that the second part 626 is configured to be brought from an inactive position to an active position by rotating the second part 626.

[0083] In the illustrated embodiment, each of the first engaging device and the second engaging device includes flanges 624, 629 that project from the respective first part 621 and second part 626 at substantially right angles. Alternative configurations, such as discrete spikes, are also conceivable.

[0084] Hinge assembly and coupling unit - Figures 6 to 7 and Figure 22 and Figure 23

[0085] First, referring to Figure 6 and Figure 7 , it is shown that the roof window 1 also includes a hinge assembly 9.

[0086] The hinge assembly 9 is configured such that it allows the window frame 3 to be cantilevered in a first operating state corresponding to normal use. That is, during normal use, the window frame 3 rotates about a substantially horizontal first hinge axis α at or near the top frame member 21 and the top window frame member 31 between a closed position and an open position.

[0087] Now also referring to Figure 22 and Figure 23 , it can be seen that the hinge assembly 9 includes a hinge unit 91 having a frame hinge portion 92 that is at least connected to or can be connected to the top frame member 21, a window frame hinge portion 93 that is at least connected to the top window frame member 31, and a hinge pin 94 that connects the frame hinge portion 92 and the window frame hinge portion 93.

[0088] The term "connected to" means that the component in question is in a condition, state, or position where the component in question is actually connected to a certain part, while "can be connected to" is intended to include conditions, states, and positions where the component in question can be connected to the relevant part but is not necessarily connected to that part. In the description of Figure 22 and Figure 23 , the frame hinge portion 92, including any sub-components, will be described as being connected to a part of the frame 2.

[0089] Hereinafter, the coupling unit 95 of the hinge assembly 9 will be described in rather detail. The details of the hinge assembly 9 are described in more detail in the co-pending patent application of the applicant filed on the same day as this application.

[0090] The coupling unit 95 is configured to allow selective coupling of at least the frame hinge portion 92 of the hinge unit 91 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 a top frame coupling plate 96 and a side frame coupling plate 97. Alternative configurations are conceivable.

[0091] The top frame coupling plate 96 includes a base portion 961 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, the plurality of fastening means including at least one bolt 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 cooperates 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 serrated edge 29a and a set of openings 29c, 29e, where the opening 29e is a through-opening or through-hole.

[0092] 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, the plurality of fastening means including at least one bolt 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 accommodate the side frame coupling plate 97, the side frame member 22 includes a hinge assembly receiving serrated edge 29b and a set of openings 29d, 29f.

[0093] Operating component- Figure 8 and Figure 10

[0094] During normal use, i.e., when the roof window 1 has been installed and the user wishes to place the window frame 3 in a ventilation position, opening, closing, and stopping can be achieved with the assistance of an operating assembly, such as the manual winder or screw jack forming the operating assembly 5 as shown.

[0095] First referring to Figure 8 , the operating assembly 5 includes a window frame fitting 55, a spindle portion 52 having a spindle 521, and a handle 522. The spindle 521 is connected to a socket fitting 51 via a nut portion 53. In the installed state of the operating assembly, the window frame fitting 55 is connected to the bottom window frame member 34 and the socket fitting 51 is connected to the bottom frame member 24, such that when the spindle portion 52 rotates relative to the nut portion 53, the bottom window frame member 34 moves relative to the bottom frame member 24.

[0096] 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 spindle portion 52 and the nut portion 53 and the socket fitting 51 are provided separately from the roof window 1.

[0097] The nut portion 53 includes a nut ring 531 which is connected here to a set of flanges 512 protruding from the base plate 511 of the socket fitting 51 by means of a set of bolts 532. A hole 513 is provided in the base plate 511 for mounting the socket portion 51 to the bottom frame member 24.

[0098] The operating assembly 5 further includes a split 56 associated with the window frame fitting 55 which is displaceable between an active position in which it engages with a set of openings 553 in a set of flanges 552 protruding from the base plate 551 of the window frame fitting 55 and an inactive position in which an accommodation gap is shown between the flanges 552 of the window frame fitting 55.

[0099] The spindle portion 52 includes an end portion 54 configured to cooperate with the window frame fitting 55 in the installed state.

[0100] Window frame and frame structure- Figures 5 to 16

[0101] As Figure 8 and Figure 9 shown in the cross-sectional view of the bottom portion of the roof window 1 in Figure 4 and Figure 5 , the pane 4 includes an outer sheet 41 and at least one inner sheet, here two inner sheets 42, 43 being placed in contact with each other. The pane 4 is here a so-called stepped pane, where the outer sheet 41 includes an extension 41a extending beyond the bottom edge portions 42b of the inner sheets 42, 43 to the bottom edge portion 41b of the outer sheet 41. Also referring now to

[0102] What all the window frame members 31, 32, 33, 34 of the window frame 3 according to the invention have in common is that each window frame member includes: profile elements 31a, 32a, 34a, inner elements 31c, 32c, 34c and intermediate elements 31b, 32b, 34b. Although not indicated, the side window frame member 33 not shown in cross-section has a configuration similar to that of the side window frame member 32 shown.

[0103] The intermediate elements 31b, 32b, 34b of the respective window frame members 31, 32, 33, 34 form a connection between the profile elements 31a, 32a, 34a and the internal elements 31c, 32c, 34c of the window frame members 31, 32, 33, 34 under discussion. For all four window frame members, the intermediate elements 31b, 32b, 34b of the window frame members 31, 32, 33, 34 can in principle be formed in the same way or with individual characteristics. However, generally the two side window frame members 32, 33 of the window frame 3 will be designed to have the same properties.

[0104] Also referring Figure 12a , in the illustrated embodiment, the intermediate element 31b of the top window frame member 31 and the intermediate elements 32b, 33b of the two side window frame members 32, 33 are formed as a group of longitudinal profiles, while the intermediate element 34b of the bottom window frame member 34 includes a group of individual fittings, which will be described in more detail in conjunction with Figure 14a -b. The details of the respective intermediate elements 31b, 32b, 33b, 34b will be described below.

[0105] The internal elements 31c, 32c, 33c, 34c of the window frame members 31, 32, 33, 34 form a continuous internal element window frame structure that supports the inner edge portions of the window panes 4. That is, when viewed from the inside, the edge portions of the window panes 4 partially overlap with the internal elements 31c, 32c, 33c, 34c. In this way, the top edge portion 4c, the side edge portions 4b and the opposite side edge portions, as well as the bottom edge portion 42b of the inner sheet 42, are all positioned on the outer side of the continuous window frame structure provided by the internal elements, so that any spacers 47 and other elements present along the edge portions of the window pane 4 are obscured by the internal elements 31c, 32c, 33c, 34c and are thus not visible from the inside of the building. The internal members 31c, 32c, 33c, 34c of the window frame members 31, 32, 33, 34 can have substantially the same cross-section and be formed of any suitable material, such as wood joined in a mortise joint at the corners. It is also contemplated to form the internal element structure as a completely continuous structure, for example, by molding.

[0106] As will also 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 respective 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 engaging means 32b3, 34b3 that are configured to form a structural connection with the internal elements 32c, 34c at one of at least two different positions in the height direction.

[0107] Figure 5 and Figure 6 also indicates the hinge assemblies 9 present in the gaps between the top window frame member 31 and the top frame member 21, as well as in the gaps between the side window frame members 32 and the side frame members 22. The window frame 3 is connected to the frame 2 by the hinge assemblies 9 to provide a top-hung hinge connection.

[0108] Regarding the frame 2 of the roof window 1, each frame member 21, 22, 23, 24 includes a plurality of receiving structures located inside, outside, on the inner side, and / or on the outer side of the respective frame member. Each receiving structure is configured to interact with auxiliary devices in the assembled state of the frame 2.

[0109] In the illustrated embodiment, the top frame member 21 and the two side frame members 22, 23 have substantially the same cross-section.

[0110] Specifically referring to Figure 8 and Figure 9 , the bottom frame member 24 includes an outer plate 24a and a separate inner plate 24b. The outer plate 24a and the separate inner plate 24b can be formed of 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.

[0111] Another feature of the roof window 1 in the illustrated embodiment is that the frame 2 includes at least one releasable component configured to allow replacement with different sets of components to change the function of the roof window 1.

[0112] In the illustrated embodiment, one such releasable component includes a cover 24c, which is releasably connected to the remaining parts of the bottom frame member 24 and defines a cavity relative to the remaining parts of the bottom frame member 24. The cover 24c can be formed of any suitable material, such as a profile element of plastic or metal material.

[0113] Here, the bottom frame member 24 includes an outer plate 24a and a separate inner plate 24b. The cavity defined by the cover 24c is defined by the inner side portion of the outer plate 24a in the outward direction and is mainly defined by the outer side portion of the separate inner plate 24b towards the inside.

[0114] To obtain a releasable connection, the edge portions 24c1, 24c2 of the cover 24c are received in receiving grooves in the bottom frame member 24, specifically in a receiving groove 24a1 in the outer plate 24a and a receiving groove 24b1 in the separate inner plate 24b.

[0115] In the illustrated embodiment, wherein the roof window 1 is prepared for manual operation by means of the operating assembly 5, a heat insulator 24d is accommodated in the cavity defined by the cover 24c.

[0116] In order to change the function of the roof window 1, the cavity defined by the cover 24c is configured to receive an electric actuator (not shown), and the cover 24c is configured to be replaced by a different cover (not shown) that allows the operating device of the electric actuator to be connected to the window frame 3.

[0117] It is also contemplated that the window frame fitting 55 that allows connection to the bottom window frame member 34 can be selectively connected to such an electric actuator, in which case the window frame fitting 55 simply duplicates the operating device for the electric actuator.

[0118] Similarly, it is contemplated that the roof window 1 is provided in the case where the bottom frame member 24 includes a dummy element configured to be replaced by the socket fitting 51 of the operating assembly 5.

[0119] Accordingly, if the roof window 1 is provided in a basic form of a hinge different from the hinge assembly 9 described in the above embodiments, it is also contemplated to use a blanking plate to cover the hinge assembly to receive the serrated edges 29a, 29b to allow the replacement of the previous hinge with the hinge assembly 9.

[0120] The first receiving structure includes the lining grooves 25 on the inner sides of each of the frame members 21, 22, 23, 24. The lining grooves 25 are configured to interact with a set of internal lining panels. Such lining panels generally form a transition between the roof window 1 and the internal wall. In the bottom frame member 24, a first groove portion 25a is provided in the outer plate 24a, and a second groove portion 25b is provided in the separate inner plate 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.

[0121] In the illustrated embodiment, when viewed from the inside, each of the frame members 21, 22, 23, 24 includes inwardly projecting portions 21i, 22i, 24i that at least partially overlap the corresponding window frame members 31, 32, 33, 34. This is possible since when the window frame 3 is opened relative to the frame 2, all parts of the window frame 3 move towards the outside.

[0122] The second receiving structure includes the sealing grooves 26 located on the outer sides of the inwardly projecting portions 21i, 22i, 24i. The sealing grooves 26 are configured to interact with the frame sealing profile 26p.

[0123] The third receiving structure includes the first outer grooves 27 located on the outer sides of the frame members 21, 22, 23, 24. The first outer grooves 27 are configured to interact with the corresponding plates 71, 72, 73, 74 of the heat-insulating frame 7. The interaction can occur by introducing the longitudinal protrusions 78 of the heat-insulating frame plates into the grooves, or by correctly positioning separate fastening devices.

[0124] Looking again from the perspective of what the user sees from the interior of the building, a roof window 1 is installed on the roof, and it is also noted that the inwardly projecting portions 21i, 22i, 24i of each of the frame members 21, 22, 23, 24 all have inward-facing surfaces, and the inward-facing surfaces together form a continuous inward-facing surface. As pointed out, this appearance mimics the corresponding continuous inward-facing surface of the window frame 3.

[0125] The fourth receiving structure includes a joint unit groove 28 located on the outer sides of the top frame member 21 and the two side frame members 22, 23. The joint unit groove 28 interacts with the corresponding top joint element 81 and side joint elements 82, 83 of the joint unit 8, and the function of the joint unit groove 28 will be further described below.

[0126] Other details visible in the drawings include guide elements 22g (see Figure 7 ) and guide elements 32g (see Figure 10 ), and the guide elements 22g and 32g determine the alignment of the window frame 3 relative to the frame 2 when closing the window frame, so that any skew occurring in the open position of the window frame 3 is eliminated. The shielding mounting bracket 32s is visible in Figure 8 , and an internal shielding device (not shown) can be installed in the window frame 3 through the shielding mounting bracket to provide shielding for the window pane 4. The abutting element 22s provides a stop for the bottom window frame member 34 during closing.

[0127] Details of the heat-insulating frame 7 are also shown in these drawings; as mentioned above, the heat-insulating frame 7 includes a top plate 71, side plates 72, 73 and a bottom plate 74. In the illustrated embodiment, each such heat-insulating frame plate includes a protrusion 78 to be received in the outer portion of the corresponding frame member and a dent 75 that interacts with auxiliary equipment having the form of a sleeve under the roof described in more detail in a co-pending patent application of the applicant filed on the same day as this application. With particular reference to Figure 11 , a recess 76 for making room for the mounting bracket 6 to be installed on the side frame member 23 of the frame 2 is shown, as well as a fold line 77 that allows a part of the side plate 73 of the heat-insulating frame 7 to be folded backward to allow access to the outer side of the side frame member 23. Such recesses 76 and fold lines 77 are provided at or near the location where the mounting bracket 6 of a set of mounting brackets for the roof window 1 is expected to be located on at least the side plates 72, 73 of the heat-insulating frame 7. The heat-insulating frame 1 can in principle be made of any material with appropriate heat-insulating properties. Currently, it is preferred to use a foam material, such as polyethylene foam.

[0128] Intermediate element- Figures 5 to 16

[0129] Now referring to the description of the connections between the components of the window frame 3, the joining of the intermediate elements 31b, 32b, and 33b of the top window frame member 31 with the two side window frame members 32, 33, and with the corresponding internal elements 31c, 32c, 33c will first be described.

[0130] In particular, referring to Figure 16 , on the outer side of each internal element, here the outer side of the internal element 32c of the side window frame member 32 as shown, there is provided a receiving device configured to receive the joining device of the intermediate element 32b of the side window frame member 32.

[0131] In the illustrated embodiment, the receiving device includes two longitudinally extending grooves 32c1, 32c2 spaced apart from each other in the height direction, and the grooves are open in the outward direction of the roof window 1.

[0132] In the illustrated embodiment, 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 fiber.

[0133] Therefore, only one of these intermediate elements, namely the intermediate element 32b, will be described in detail. Now referring to Figure 15 , the intermediate element 32b includes a base portion 32b1 that extends substantially in the height direction in the assembled state of the window frame 3 and a head portion 32b2 that extends at an angle to the base portion 32b1. As Figure 16 shown, the base portion 32b1 is provided with a joining device on the inward-facing surface in the assembled state, and this surface faces the outer surface of the internal element 32c. Figure 3 , Figure 4 , Figure 5 , Figure 10 and Figure 12a also present the positions, orientations, and lengths of the individual intermediate elements 31b, 32b, and 33b.

[0134] In the illustrated embodiment, the joining device of the base portion 32b1 of the intermediate element 32b includes a protruding portion formed as a flange 32b3, and the flange 32b3 extends over the entire length of the profile and is configured to engage with a selected one of the grooves 32c1, 32c2 of the internal element 32c of the side window frame element 32.

[0135] The base portion 32b1 of each intermediate element 32b includes a stepped portion 32b4 offset in an inward direction by an offset bend 32b5 relative to the remainder of the base portion 32b1. A joining device, here a flange 32b3, is provided in the stepped portion 32b4.

[0136] An additional fastening device 30x (see Figure 12a and Figure 16 ) is provided to fasten the intermediate element 32b to the inner element 32c of the side window frame 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, i.e., the opening 32b6 is in the stepped portion 32b4.

[0137] Now specifically referring to Figure 14a and Figure 14b , the connection between the intermediate element 34b and the inner element 34c of the bottom window frame member 34 will be described in detail.

[0138] Just as the intermediate elements 31b, 32b, 33b described above, the intermediate element 34b includes a base portion 34b1 extending substantially in the height direction and a head portion 34b2 extending at an angle to the base portion 34b1. The base portion 34b1 is provided with a joining device 34b3 on an inner surface facing the outer surface of the inner element 34c. The joining device of the base portion 34b1 includes a protruding portion 34b3 that engages with a selected one of the grooves 34c1, 34c2 of the inner element 34c of the bottom window frame member 34. An additional fastening device 30y is provided in an opening 34b6 in a stepped portion 34b4 offset in an inward direction by an offset bend 34b5 relative to the remainder of the base portion 34b1 to fasten the intermediate element 34b of the bottom window frame member 34 to the inner element 34c.

[0139] In the illustrated embodiment, the intermediate element 34b of the bottom window frame member 34 includes a set of fittings. Two such sets can be provided along the length of the bottom window frame member 34.

[0140] Each set of fittings includes a connecting fitting provided with a joining device configured to form a structural connection with an internal element 34c at one of at least two different positions in the height direction. The connecting fitting includes a first fitting part 34b0 and a second fitting part 34b10. The first fitting part 34b0 includes the joining device, and the second fitting part 34b10 is configured to be connected to the first fitting part 34b0 to serve as a spacer between the external surface of the internal element 34c of the bottom window frame member 34 and the first fitting part 34b0. To connect the first fitting part 34b0 and the second fitting part 34b10 to each other, the second fitting part 34b10 is provided with at least one elastic hook-shaped member 34b11 configured to interact with a corresponding opening 34b12 in the first fitting part 34b0. In the assembled state of the window frame 3, the head part 34b2 of the intermediate element 34b of the bottom window frame member 34 is received in a slit 34a5 in the inner part 34a2 of the profile element 34a of the bottom window frame member 34.

[0141] Comparative Embodiment- Figure 17 and Figure 18

[0142] Now referring to Figure 17 and Figure 18 which are simplified schematic views showing the main components of the side window frame member 32, it can be seen how the same components of the window frame 3 can accommodate window panes 4 of two different thicknesses. This is achieved by changing the position of the joining device of the intermediate element 32b from the first groove 32c1 to the second groove 32c2. This will require a slightly adapted side frame member 22c. The intermediate elements 31b, 33b, 34b at the other window frame members 31, 33, 34 are moved similarly.

[0143] Profile element- Figures 19 to 21

[0144] Now the focus will be on the profile elements of the window frame 3. In Figures 3 to 6 and Figure 10 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 is shown in perspective views, while details are shown in the cross-sectional view of Figure 16 . The profile element 34a of the bottom window frame member 34 is most clearly shown in Figures 12a to 14b .

[0145] Corresponding to the above, only the profile element 32a of the side window frame member 32 will be described to represent the longitudinal profiles of the top window frame member 31 and the two side window frame members 32, 33, because in the illustrated embodiment, these profile elements are formed as a set of longitudinal profiles having a substantially uniform cross-section.

[0146] Common details of all the profile elements 31a, 32a, 33a, 34a are as follows:

[0147] Each profile element 32a, 34a includes a head portion 32a1, 34a1 and an adjacent outer portion 32a3, 34a3.

[0148] The head portions 32a1, 34a1 are substantially parallel to the plane of the roof window 1 in the assembled state of the roof window 1, while the adjacent outer portions 32a3, 34a3 are substantially perpendicular to the head portions 32a1, 34a1.

[0149] However, the head portion 32a1 of the profile element 32a of each of the top window frame members 31 and the side window frame members 32, 33 is positioned outside the outer pane surface 4e of the pane 4 and outside the side edge portion 4b and the top edge portion 4c of the pane 4, while the head portion 34a1 of the profile element 34a of the bottom window frame member 34 is positioned inside the extension portion 41a of the outer sheet 41 of the pane 4.

[0150] The profile element 32a of the side window frame member 32 and the profile element 34a of the bottom window frame member 34 are thus separated by a layer of glass; however, an overlap is provided by selecting the lengths of the profile elements 32a, 33a of the two side window frame members 32, 33 to substantially correspond to or slightly exceed the distance between the top edge portion 4c of the pane 4 and the bottom edge portion 41b of the outer sheet 41 of the pane 4. The length of the profile element 34a of the bottom window frame member 34 is appropriately selected to substantially extend to the side edge portion 4b of the pane 4.

[0151] The length of the profile element 31a of the top window frame member 31 is selected according to the size of the pane 4 and the manner required to connect the profile element 31a to the profile elements 32a, 33a. In the illustrated embodiment, see Figure 19 , in the assembled state of the window frame 3, the longitudinal profiles form a miter joint between the profile element 31a of the top window frame member 31 and the corresponding profile elements 32a, 33a of the side window frame members 32, 33.

[0152] In Figures 12a to 13b it is also visible the end plug 38 that plugs the profile element 32a of the side window frame member 32. The end plug 38 is provided with ribs and snap arms for increasing friction not described in detail. The glass spacer 45 is provided with a corresponding end plug. In addition, a trailing element 37 is provided to drain any condensate to the profile element seal 34p.

[0153] See Figures 19 to 21 , to ensure a tight connection at the miter joint, a corner key 39 is provided at each miter joint. During the manufacturing process, a sealant 39b is appropriately applied as will be described in particular below with reference to Figures 19 to 21 .

[0154] The corner key 39 generally has an L-shaped configuration, where two perpendicular legs 39a1 are separated by a channel 39a2. In the channel 39a2, a set of main openings 39a3 is provided.

[0155] Furthermore, each leg 39a1 abuts against a hanging skirt 39a4 on the first side. Here, secondary openings 39a5 are provided.

[0156] In order to fit the profiles of the profile elements 31a, 32a, 33a, each leg 39a1 abuts against an inclined portion 39a6 on the second side.

[0157] As Figure 20 and Figure 21 shown in

[0158] The profile elements 31a, 32a, 33a are suitably configured to receive the pane 4 in an inverted attitude, the inverted position being one in which the corresponding head portion 32a1 faces a substrate such as an assembly table. After the intermediate elements 31b, 32b, 33b have been introduced into the corresponding profile elements 31a, 32a, 33a, this step of assembling the window frame 3 can be carried out. As Figure 16 and Figure 19 also visible in

[0159] Each longitudinal profile in the longitudinal profiles of the profile elements 31a of the top window frame member 31 and the profile elements 32a, 33a of the two side window frame members 32, 33 includes an inner portion 32a2 adjacent to the head portion 32a1. The dimensions are selected such that the inner portion 32a2 overlaps the pane 4 in the assembled state of the window frame 3.

[0160] The head portion 32a1 of each profile element 31a, 32a, 33a is configured to protrude externally relative to the outer surface 4e of the pane in the assembled state of the window frame 3.

[0161] 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 and internally towards the outer surface 4e of the pane.

[0162] The inner portion 32a2 abuts against a first bending portion 32a4 configured to be positioned at or near the outer surface 4e of the pane.

[0163] A second bending portion 32a5 is provided, for example Figure 16As shown in []. The second bending portion 32a5 has the function of accommodating the seal 4p relative to the outer surface 4e of the pane.

[0164] A third bending portion 32a6 is also provided, and the third bending portion 32a6 is configured to accommodate the inner edge portion 32b9 of the intermediate element 32b relative to the inner side portion of the inner portion 32a2. For a detailed schematic view of the intermediate element 32b, refer to Figure 15 .

[0165] A transition portion 32a7 is provided between the head portion 32a1 and the inner portion 32a2. The transition portion 32a7 is configured to accommodate the ridge portion 32b7 of the intermediate element 32b.

[0166] The outer portion 32a3 of the adjacent profile element 32a is provided with a fourth bending portion 32a8. The fourth bending portion 32a8 is configured to accommodate the outer edge portion 32b12 of the intermediate element 32b.

[0167] In the assembled state of the window frame 3, the inner portion 32a2 of the profile element 32a is configured to be positioned opposite to the inner inclined portion 32b8 of the intermediate element 32b.

[0168] Finally, the outer edge portion 32b12 of the intermediate element 32b is associated with the head portion 32b2 of the intermediate element 32b via the outer inclined portion 32b11 and the bending portion 32b10.

[0169] In summary, the configuration of the described embodiment enables a firm engagement to be provided between the intermediate elements 31b, 32b, 33b and the profile elements 31a, 32a, 33a.

[0170] The lengths of the intermediate elements 32b, 33b of the side window frame members 32, 33 can be selected to be slightly shorter than the associated profile elements 32a, 33a.

[0171] At the bottom window frame member 34, the head portion 34a1 of the profile element 34a is provided with at least one longitudinally extending groove 34a4 for receiving the corresponding sealing strip 4s. These sealing strips 4s can be made of silicone to form an adhesive connection between the profile element 34a and the extension portion 41a of the outer sheet 41 of the pane 4. A mask 44 can be provided at the extension portion 41a on the inner side portion of the outer sheet 41.

[0172] As described above, the intermediate elements 31b, 32b, 33b, 34b of each window frame member 31, 32, 33, 34 include engaging means 32b3, 34b3 configured to form a structural connection with the inner elements 31c, 32c, 33c, 34c. See Figures 14a to 14b, to also fasten the intermediate element 34b of the bottom window frame 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 window frame member 34 in the assembled state of the window frame 3. To increase the strength of the inner portion 34a2, this portion may be formed as a two-layer folded portion.

[0173] The window frame 3 can in principle be manufactured in any suitable manner. Hereinafter, a currently preferred method will be described:

[0174] In a first step, a set of profiles consisting of three longitudinal profiles is provided. For example, the longitudinal profiles may form a single profile length of an extruded material of a metal such as aluminum, for example. Other materials and manufacturing processes may be envisaged, including roll forming of steel or other metals or roll forming of composite materials.

[0175] Secondly, miter shapes are formed at the mutually facing ends of the longitudinal profiles. If the longitudinal profiles consist of a single length and if convenient, the miter shape can be formed in a continuous length by appropriately formed cuts that form internal corners at the intersections between the top and the sides.

[0176] A pane of appropriate dimensions is provided, for example as described above.

[0177] A set of elements consisting of four inner elements and four intermediate elements is provided, for example as described above.

[0178] Now the longitudinal profiles are placed in an inverted position on the assembly table to form a profile element frame structure that constitutes three sides of a rectangle. This is usually achieved by guide elements that can be fixed to the assembly table corresponding to the outer periphery of the window frame.

[0179] The pane is placed within the profile element frame structure, and the profile element frame structure is connected to the inner elements to form the window frame, optionally via the intermediate elements. During this process, the intermediate elements at the top and the sides are usually inserted into the corresponding profile elements. The plurality of inner elements can be interconnected as described above to form an inner element frame structure that is placed on the pane, and subsequently, the intermediate elements are connected to the respective inner elements.

[0180] Briefly referring back Figures 19 to 21 , before placing the pane 4 within the profile element frame structure, a set of two corner keys 39 placed within the longitudinal profile elements 31a, 32a, 33a at the mutually facing mitered ends is advantageously provided. A sealant 39b is preferably applied to each corner key 39. During the assembly process, it is ensured that the sealant 39b can flow through the main opening 39a3 of the corner key 39 such that the sealant 39b is distributed.

[0181] In the illustrated embodiment, each corner key 39 is configured to be mechanically connected to a respective adjacent profile element 31a, 32a, 33a. This can be achieved by nailing, for example by techniques.

[0182] In an embodiment where the roof window 1 includes one or more glass spacers, such as glass spacer 45, the glass spacers are aligned on the assembly table before the panes 4 are placed within 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.

[0183] Sealing assembly and joining unit- Figures 24 to 36

[0184] Now specifically referring to Figures 24 to 29a , an embodiment is shown in which the roof window 1 is provided with a cover assembly 10. The details of the cover assembly 10 generally include a flashing assembly, and any other auxiliary equipment is described in more detail in the co-pending patent application of the applicant filed on the same day as this application.

[0185] Hereinafter, the sealing assembly of the roof window 1 will be described. Some details of the sealing assembly have also been described above.

[0186] The sealing assembly generally includes a set of sealing profiles.

[0187] In the illustrated embodiment, the seal between the window frame 3 and the frame 2 is provided by an outer seal plane, an intermediate seal plane, and an inner seal plane. Also refer to the cross-sectional views of the top, sides, and bottom of the roof window 1 shown and described above.

[0188] The inner seal plane includes frame seal profiles 26p provided on the outer sides of each frame member 21, 22, 23, 24 and interacting with the inner sides of the respective window frame members 31, 32, 33, 34. The window frame seal profile 30p1 is disposed in the window frame seal groove 30g1.

[0189] On the bottom side, the intermediate seal plane includes window frame seal profiles 30p1 provided on the outer sides of each window frame member 31, 32, 33, 34 and interacting with the inner sides of the respective frame members 21, 22, 23, 24.

[0190] In the closed position of the window frame 3, an outer seal plane is provided because the profile element seal 34p on the profile element 34a of the bottom window frame member 34 contacts the outer side of the bottom frame member 34.

[0191] On the top and sides, the outer seal plane is defined by the top engagement element 81 and the side engagement elements 82, 83. Specifically referring toFigure 26 and Figure 27 the similarities and differences between the top joining element 81 and the side joining elements, represented herein by the side joining element 82, in the illustrated embodiment will be described:

[0192] Each joining element 81, 82 includes 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 joining unit recess 28 in the assembled state of the roof window 1. The sealing portion 89 faces outward and interacts with the top window frame member 31 and the side window frame members 32, 33 during opening and closing of the window frame 3 and in the closed position of the window frame 3.

[0193] The inner leg 86, outer leg 87, and flange 88 together form a channel 810 in the top joining element 81 and a channel 820 in the side joining element 82. A corresponding channel is formed in the other side joining element 83. In this way, water resulting from rain or other precipitation can be guided from the channel 810 in the top joining element 81 to the channels 820 in the side joining elements 82, 83 and further outward to the cover assembly 10 (not shown in detail).

[0194] A common feature of both the top joining element 81 and the side joining element 82 in the illustrated embodiment is that the sealing portion 89 includes an inner sealing lip 891 and an outer sealing lip 892. Referring to Figure 6 and Figure 5 , the inner sealing lip 891 of both the top joining element 81 and the side joining element 82 is set sufficiently inward so that the inner sealing lip 891 interacts with the interior of the top window frame member 31 and the side window frame member 32; however, the outer sealing lip 892 of the top joining element 81 is positioned on the outer side portion of the top window frame member 31. In the illustrated embodiment, this is due to the fact that the flange 88 of the top joining element 81 is longer than the corresponding flange of the side joining element 82. It should be noted that although at least the sealing portion 89 of each joining element 81, 82, 83 is formed to be elastic, i.e., as is characteristic of a seal, the sealing portion 89 is capable of deforming when abutted against another component and then rebounding when relaxed, this is not reflected in the drawings as the drawings typically show the elements in their undeformed state. Generally, at least the sealing portion 89 has different properties from at least the base portion 80. This can be provided by co-extrusion or co-molding of two (or more) different materials.

[0195] To ensure a tight interaction at the top of the roof window 1, again referring 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.

[0196] In the illustrated embodiment, since the base portion 80, the inner leg 86, and the flange 88 form the waterproof plate receiving groove 85, the top engaging element 81 and the side engaging elements 82, 83 also allow interaction with the cover assembly 10. The waterproof plate receiving groove 85 has a groove opening 85b and is provided with a plurality of protrusions 85a.

[0197] The sealing assembly further includes a pane seal 30p2 received in the pane seal groove 30g2. It should be noted that the pane seal 30p2 remains fixed relative to the window frame 3.

[0198] Now referring 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.

[0199] In Figure 29b , a foam element 32f present in the side window frame member 32 is shown. Similar foam elements may also be present in the opposite side window frame member 33. The longitudinal extension of the foam element 32f may be such that the foam element 32f extends over most of the length of the side window frame member 32. The foam element 32f abuts against the inner side of the head portion 32b2 of the intermediate element 32b along the extent of the intermediate element 32b, and allows the foam element 32f to expand towards the inner side of the head portion 32a1 of the profile element 32a of the side window frame member 32 at the portion where the foam element 32f protrudes beyond the longitudinal ends of the intermediate element 32b. The foam element 32f has general weather protection properties.

[0200] In Figure 30 , a stabilizing plate 310x is placed in the channel 810 of the top engaging element 81 of the engaging unit 8 to improve the structural characteristics. In addition, an extension plate 310y is shown fastened to the profile element 31a of the top window frame member 31 to protrude into the channel 810. The extension plate 310y improves the guidance of precipitation into the channel 810 and is used for further guiding towards the side of the roof window. This is particularly relevant in the case of roof windows built on a steeply pitched roof. The relative positions of the stabilizing plate 310x and the extension plate 310y are shown more clearly in Figure 32 . For ease of viewing the relevant part of the engaging unit 8, Figure 33 the top engaging element 81 of the engaging unit 8 is shown without the stabilizing plate 310x and with the window frame 3 including the extension plate 310y.

[0201] Figure 31 The interaction between the bottom of the roof window 1 and the cover assembly 10 is shown.

[0202] Finally, Figure 34A view of the lower right corner of the roof window 1 is shown, wherein the sash 3 is slightly raised relative to the frame 2 for reasons of clarity.

[0203] Here, the clamp 22x is mounted on the side engaging element 82 of the engaging unit 8. The clamp 22x is provided with a clamp flange 22xa, as shown in FIG. Figure 36 The end plug 38 of the side sash member 32 is provided with an end plug flange 38a in this embodiment. In the closed position of the roof window 1, the end plug flange 38a overlaps the clip flange 22xa.

[0204] Generally speaking, the components of roof windows are easily dismantled and each component can in principle be reused, recycled or have its material recovered for other uses through appropriate environmentally responsible disposal means.
