Description

Technical Field

[0001] The present invention relates to a roof window comprising a frame, a window frame and a window pane, wherein the frame comprises a set of frame members, the set of frame members comprising 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 comprising a top window frame member, two side window frame members and a bottom window frame member, each frame member and window frame member defining a longitudinal direction, and wherein the roof window further comprises a hinge assembly, the hinge assembly being configured to allow the window frame to be top-hung about a substantially horizontal first hinge axis in a first operating state in an installed state of the roof window, and the hinge assembly comprising a hinge unit having a frame hinge portion connected or connectable to at least the top frame member and a window frame hinge portion connected to at least the top window frame member. Background Art

[0002] There are many 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 consider external appearance as well. 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 regardless of whether the installation involves the installation of a new roof window or the replacement of an existing window or skylight as part of a renovation or refurbishment project.

[0003] In the past, when windows or skylights were typically made of cast iron and a single glass pane, separated by one or more cast iron glazing bars, thermal efficiency left room for improvement. To meet the energy performance required by modern building regulations, energy-saving roof windows are often equipped with insulating panes and have begun to imitate 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 a product’s climate footprint, there is also a need for products to be more environmentally friendly in their manufacture, supply, installation and use.

[0006] Taking into account all the above requirements, there is an ongoing task to improve the fitting and operating components of 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 which is easy to handle and install.

[0008] This and other objects are achieved by a roof window of the type mentioned in the introduction, which is further characterized in that the hinge assembly comprises a coupling unit which is connected or connectable to the frame and is configured to be connected to the hinge unit in the mounted state of the roof window, in which the hinge unit is connected to the window frame and the coupling unit is connected to the frame, and in which the coupling unit and the hinge unit are configured to assume the following positions relative to each other:

[0009] i) intermediate position; and

[0010] ii) A final position, which corresponds to the installed state of the roof window.

[0011] In this way, the frame can be manipulated independently of the window frame and without having to disassemble the hinged connection to allow this operation. Furthermore, during installation, the installer can first engage the hinge unit with the coupling unit in an intermediate position. In this intermediate position, the window frame, including the hinge unit, can rest on the coupling unit, providing the installer with improved freedom. To complete the installation, the installer brings the hinge unit and coupling unit into the final position. The intermediate position can be easily reached, thus placing less demands on the engagement between the coupling unit and the hinge unit, while the final position provides increased security against inadvertent release of the connection.

[0012] In a presently preferred embodiment, the coupling unit comprises a top frame coupling plate connected to the top frame member, and the top frame coupling plate is provided with coupling plate engagement means configured to cooperate with corresponding frame hinge portion engagement means of the frame hinge portion. The presence of the top frame coupling plate, which can be connected to the frame during manufacture of the roof window, provides a well-defined engagement position for the hinge unit and thus simplifies installation of the window frame at the installation site.

[0013] Installation is improved and even further facilitated in a currently preferred embodiment in which the coupling plate engagement means comprises at least two distinct engagement portions configured to cooperate with corresponding frame hinge portion engagement means. By this design, a stepwise and fail-safe installation can be achieved.

[0014] In an advantageous development of this presently preferred embodiment, the coupling plate engagement means is movable or fixed relative to the coupling plate, and the frame hinge engagement means is fixed or movable, thus providing maximum flexibility.

[0015] To improve the flexibility in the form of the engagement means even further, the coupling plate engagement means may be a female or male engagement means and the frame hinge engagement means may be a male or female engagement means.

[0016] In a mechanically simple embodiment, the coupling plate engagement means comprises a hook-shaped element comprising an arm having a hook-like member and connected to the base portion by a swivel joint, and the frame articulated base plate comprises a protrusion constituting the frame articulated portion engagement means and configured to continuously cooperate with at least one intermediate engagement portion and a final engagement portion of the hook-shaped element. Furthermore, in addition to ensuring a safe and reliable engagement operation, this embodiment has the additional advantage of reducing friction and further minimizing the influence of inevitable manufacturing tolerances in roof windows.

[0017] Improved reliability of the structure is achieved in an embodiment in which the hook element is biased towards a locked position in which the projection of the frame hinged base plate engages the final engagement portion, and the bias is provided by a spring which is accommodated with one end in a spring receiving opening in the arm and with the other end in a spring receiving opening in the base portion, the spring passing through the opening to allow the spring to move during movement of the hook element.

[0018] In an alternative embodiment, the coupling plate engaging means includes a set of engaging pins positioned at intervals relative to one another in the height direction of the coupling plate, and the frame hinge portion engaging means includes a locking projection having a track extending in the height direction of the frame hinge portion and configured to sequentially engage the intermediate engaging pins and the final engaging pin. When the relative movement between the engaging means of the hinge unit and the top frame coupling plate occurs substantially in the vertical direction, engagement is assisted by gravity.

[0019] Improved reliability during engagement is advantageously achieved because the locking protrusion can include a fastening portion at a first end of the locking protrusion, in which the locking protrusion is fastened to the base portion of the top frame coupling plate, and a flange at a second end opposite the first end.

[0020] Other proposed preferred embodiments and other advantages will be apparent from the following detailed description and accompanying drawings.

[0021] 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

[0067] 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.

[0068] Note that terms such as "upper," "lower," "left-hand side," "right-hand side," "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, in its installed state. 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.

[0069] General description of roof windows - Figure 1 and Figure 2

[0070] 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).

[0071] A roof window 1 includes a frame 2, a sash 3, and a window pane 4. The frame 2 includes a set of frame members, which include a top frame member 21, two side frame members 22 and 23, and a bottom frame member 24. Correspondingly, the window pane 3 includes a set of window frame members, which include a top window frame member 31, two side window frame members 32 and 33, and a bottom window frame member 34. Although the frame 2 and window frame 3 are described as rectangular structures, some principles of the proposed concept can also be applied to other geometric shapes.

[0072] 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. 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 the frame 2 and the window frame 3 are connected to each other, for example in the installed position when the roof window 1 is ready for use. Correspondingly, 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. The term "main components" should be understood to include the essential parts that are necessary for the roof window to perform all its operating functions, without including accessories or auxiliary equipment.

[0073] Inner pane surface 4i faces the interior, typically the room below the roof surface of the building in which roof window 1 is installed. Outer pane surface 4e is fitted with glass bars 45, and inner pane surface 4i is fitted with glass bar covering 46. Although less practical, a two-part pane is also possible, with two panes divided into two equal parts by a continuous glass bar. In wide roof windows, more than one glass bar may be provided, for example, two glass bars dividing the surface of the pane visible from the outside into three parts.

[0074] 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.

[0075] Figure 1 and Figure 2Other details shown in FIG include an operating assembly 5, which is shown here as a manual winder or screw jack. Other operating assemblies may also be present.

[0076] 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.

[0077] Finally, there is shown an insulating frame 7. Insulation by means of 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.

[0078] In the following description of various embodiments, elements having the same or similar functions are always provided with the same reference numerals. Suitable variations and modifications will be apparent to those skilled in the art.

[0079] Mounting bracket and roof window having a set of mounting brackets - Figures 3 to 6

[0080] Typically, roof windows, e.g. Figure 1 and Figure 2 The 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 will generally be identical, although variations are possible.

[0081] 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.

[0082] In the embodiment shown, the second support leg 62 is provided with a first engagement means 624 in a first portion 621 of the second support leg 62 and with a second engagement means 629 in a second portion 626 of the second support leg 62 .

[0083] 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.

[0084] The first engagement means 624 is configured to be received in one receiving structure of the outer side of the frame member when the mounting bracket 6 is in the mounted state 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 only in its active position when the mounting bracket 6 is in the mounted state on the frame 2 of the roof window 1. Figure 4 , in which 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 each of the side frame members 22, 23 comprises a plurality of receiving structures at the outer side portion of the respective side frame member, so 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 at a distance from each other in the longitudinal direction of the side frame member 22 in the height direction, with the first outer groove 27 being located outside the second outer groove 27b as seen in the height direction.

[0085] Briefly referring to Figure 41, the mounting bracket 6 in the supply state is shown, wherein the second engagement device 629 is in its inactive position. In this position, i.e., in the inactive position of the second engagement device 629, the second part 626 with the second engagement device 629 is accommodated in the opening 620 in the first part 621.

[0086] In order to bring the second part 626 having the second coupling device 629 from a position in the opening 620 to a position where the second part 626 is roughly positioned at an extension of the first part 621, the second part 626 having the second coupling device 629 is connected to the first part 621 via a hinged connection 625, so that the second part 626 is configured to be brought from the inactive position to the active position by rotating the second part 626.

[0087] 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.

[0088] In order to securely fasten the mounting bracket 6 to the outer side of the side frame member 22, each of the first and second parts 621 of the second bracket leg 62 comprises one or more openings 622, 623, 627, 628 for receiving fastening means in the mounted state of the mounting bracket 6 on the frame 2 of the roof window 1. Such fastening means typically comprise screws (not shown).

[0089] like Figure 5As shown in FIG, the first portion 621 is provided with an offset portion 621a. This allows for the accommodation of auxiliary equipment including bushings under the roof. Details of such auxiliary equipment are described in more detail in the applicant's co-pending patent application filed on the same day as the present application.

[0090] To allow for alternative installation of the mounting bracket 6 at different height positions on the side frame member 22, the second portion 626 is provided with an offset portion 626a that matches the offset portion 621a, so that the offset portion 626a of the second portion 626 is positioned to be generally aligned with the offset portion 621a of the first portion 621 in the inactive position of the second portion 626 of the second bracket leg 62 of the mounting bracket 6.

[0091] Correct positioning in the height direction ensures that fastening means, such as screws (not shown) for fastening the second bracket leg 62 to the side frame member 22, can be sized to an appropriate length and diameter to be received in a sufficient material thickness of the side frame member 22. For example Figure 4 As shown in FIG, the side frame members 22 have a greater material thickness towards the inside; thus, it is suitable to ensure that the fastening device enters this area.

[0092] In particular, this ensures that at least one opening 622, 628 in each of the first portion 621 and the second portion 626 crosses the respective offset portion 621a, 626a. The opening 620 of the first portion 621 crosses the bend 614, and the engagement means 629 of the second portion 626, when in the inactive position, is received in a portion of the opening 620 that crosses the bend 614. The first bracket leg 61 includes one or more openings 612, 613 for receiving fastening means for fastening the mounting bracket 6 to the roof structure when the mounting bracket 6 is mounted on the frame 2 of the roof window 1.

[0093] As mentioned above, the mounting bracket 6 has a supply state in which the second engagement means 629 is in its inactive position. In order to ensure that the mounting bracket 6 is brought to the installation state and subsequently mounted at the correct height, i.e. Figure 4In the height position shown in FIG, the second portion 626 is provided with a protrusion 626b configured to face outwardly away from the outer side of the frame member in the installed state when the engagement means 629 of the second portion 626 is in its active position, and to face inwardly toward the outer side of the frame member in the installed state when the engagement means 629 of the second portion 626 is in its inactive position. In this way, the protrusion 626b acts as a protection to prevent the mounting member from not bringing the second portion 626 with the second engagement means 629 to its active position and / or positioning the mounting bracket 6 at a more internal position on the side frame member 22, because the protrusion 626b in this case would contact the outer side of the side frame member 22, making surface contact impossible.

[0094] If it is actually necessary to position the mounting bracket 6 further inward in the height direction of the side frame member 22, other receiving structures (not shown) can be provided on the outer side of the side frame member 22 to accommodate the protrusion 626b of the second portion 626 while the first engaging device 624 is received in the second outer groove 27b.

[0095] exist Figure 3 and Figure 4 Also observable is a joining unit 8 which is mounted to the frame 2 and which has a number of functions relative to the other components of the roof window 1, including serving as a seal for the window frame 3 and for accommodating auxiliary equipment including a covering assembly (not shown) which provides a weatherproof transition to the surrounding roof.

[0096] Hinge assembly, first operating state- Figures 7 to 14

[0097] First refer to Figure 7 and Figure 8 , which shows that the roof window 1 further comprises a hinge assembly 9 .

[0098] 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.

[0099] Now also refer to Figures 12 to 14 It can be observed that the hinge assembly 9 includes a hinge unit 91, which has a frame hinge portion 92 connected or connectable to at least the top frame member 21, a window frame hinge portion 93 connected to at least the top window frame member 31, and a hinge pin 94 connecting the frame hinge portion 92 with the window frame hinge portion 93.

[0100] 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 "capable of being connected 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. Figures 12 to 14 In the description of the frame hinge portion 92 including any sub-components will be described as being connected to the parts of the frame 2. Further below, the possibility of providing a frame hinge portion 92 and sub-components that can be connected to the parts of the frame 2 will be described in more detail.

[0101] The frame hinge portion 92 includes a frame hinge base plate 921 connected to the inner side of the top frame member 21 and provided with a receiving structure 922 for a hinge pin 94 that defines a hinge axis, and the window frame hinge portion 93 includes a window frame hinge base plate 931 connected to the outer side of the top window frame member 31 and provided with a receiving structure 932 for the hinge pin 94, so that the hinge unit 91 forms a pin-barrel hinge.

[0102] In the illustrated embodiment, the receiving structure 922 of the frame hinge portion 92 forms a two-part cylinder, cylinder portions 922a, 922b surrounding a cylinder 932 formed by the receiving structure of the sash hinge portion 93. A gap is provided between the cylinder 932 of the sash hinge portion 93 and the cylinder portions 922a, 922b to accommodate manufacturing tolerances.

[0103] The frame hinge base plate 921 is generally parallel to the inner side of the top frame member 21 in the installed state, and the sash hinge base plate 931 is generally parallel to the frame hinge base plate 921 in the closed position of the sash 3 .

[0104] In addition, the receiving structure 922 of the frame hinge part 92 is connected to the frame hinge base plate 921 via the inclined part 923, and the receiving structure 932 of the window frame hinge part 93 is connected to the window frame hinge base plate 931 via the inclined part 933, so that the first hinge axis α is offset outward relative to the base plate 921 of the frame hinge part 92.

[0105] Although not shown in these figures, the hinge assembly 9 can include a set of hinge units 91 connected or connectable to the top corners of the frame 2 and the window frame 3, such that one hinge unit 91 is connected to the top corners of the top frame member 21 and the one side frame member 22 and the top sash member 31 and the one side sash member 32, while another, preferably mirror-inverted, hinge unit is connected or connectable to the top corners of the top frame member 21 and the other side frame member 23 and the top sash member 31 and the other side sash member 33.

[0106] Although each hinge unit 91 can, in principle, be connected only to the top frame member 21 and the top sash member 31, the illustrated embodiment provides for the hinge unit to also be connected to the adjacent side frame member and side sash member. Thus, the frame hinge base plate 921 is connected, here as a one-piece, integral connection, to the frame hinge side flange 924, and the frame hinge side flange 924 is connected to the inner side of the side frame member 22. Portions of the frame hinge base plate 921 and the frame hinge side flange 924 are offset from other portions, but generally speaking, the frame hinge side flange 924 extends substantially perpendicularly to the frame hinge base plate 921 from a transition portion 924a to a free end portion 924b.

[0107] Correspondingly, the sash hinge base plate 931 is connected to the sash hinge side flange 934, preferably as a one-piece integral connection, and wherein the sash hinge side flange 934 is connected to the inner side of the side sash member 32. As with the frame hinge portion 92, the sash hinge side flange 934 generally extends substantially perpendicular to the sash hinge base plate 931 from the transition portion 934a to the free end portion 934b, although some portions may be offset from other portions.

[0108] A secondary hinge pin 927 is provided at the free end portion 924b of the frame hinge side flange 924 (at Figure 14 In this way, the hinge assembly 9 provides a means for allowing the sash 3 to rotate about a second, generally horizontal hinge axis β at a distance from the top frame member 21 and the top sash member 31 .

[0109] The hinge assembly 9 can thus place the roof window 1 in a second operating state in which a plurality of other open positions can be achieved. As will be described further in the description, means are provided for allowing the frame hinge base plate 921 to be disconnected from the top frame member 21 in order to allow the sash 3 to rotate about the second hinge axis β.

[0110] In order to ensure that the movement of the window frame 3 is limited, the hinge unit 91 may be provided with an opening limiting device. In the embodiment shown, there are two independent opening limiting devices, but other configurations including only one opening limiting device are envisaged.

[0111] The first opening limiter 925 is provided by an arm 9251 rotatably connected to a sash member or frame member, and the arm 9251 includes a track 9253 that engages a pin 9254 on the frame member or sash member. The arm 9251 is rotatably connected to the sash hinge side flange 934 at a rotatable joint 9252, and wherein a pin 9254 that interacts with the track 9253 is provided on the frame hinge side flange 924.

[0112] A second opening restriction is contemplated in that an abutment notch 9255 is provided on the frame hinge side flange 924 and is configured to cooperate with a stop pin 971g provided at the side frame member 22, which in the embodiment shown is located on the side frame coupling plate 97 ( Figure 19 ) on the side frame member. The stop pin can alternatively be provided on the side frame member 22 itself.

[0113] Although coupling of the frame hinge portion 92 with the top frame member and the side frame members by means of coupling units 95 will be described below under a separate heading, the connection between the sash hinge portion 93 and the top sash member and the side sash members is uncomplicated:

[0114] The sash hinge portion 93 includes a plurality of fastening means to allow the sash hinge portion 93 to be connected to the sash 3, preferably including one or more holes 935 in the sash hinge base plate 931, one or more holes 937 in the sash hinge side flange 934, and / or pegs 938 in the sash hinge side flange 934. The top sash member 31 and the side sash members 32, 33 include appropriate receiving means (not shown).

[0115] Other details visible in the figures depicting the first operating state of the roof window include the guide element 22g (see Figure 8 ) and guide elements 32g (see FIG11 ), which 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.

[0116] These figures also show details of the insulating frame 7; these details include a top part 71, side parts 72, 73 and a bottom part 74. In the embodiment shown, each such insulating frame piece includes 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 bushing 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 11b , showing a recess 76 that makes room for a mounting bracket 6 to be mounted on the side frame members 23 of the frame 2, and a fold line 77 that allows a portion of the side part 73 of the insulating frame 7 to be folded back to allow access to the outer side of the side frame member 23. At least the side parts 72, 73 of the insulating frame 7 are provided with such a recess 76 and fold line 77 at or near the intended location of the mounting bracket 6 in a set of mounting brackets supplied to the roof window 1.

[0117] Finally, a number of features visible in the drawings but not directly relevant to the present invention include the configuration of the components of the window frame 3, namely, the configuration of the components including the profile elements, intermediate elements, and internal elements, and the configuration of the bottom frame member 24, including the outer member 24a, the separate inner member 24b, the cover 24c, and the insulating member 24d. The details of the configuration are described in more detail in the applicant's co-pending patent application filed on the same day as the present application. Exemplary elements include: the profile element 31a; the intermediate element 31b and the internal element 31c of the top window frame member 31; the profile element 32a, the intermediate element 32b, and the internal element 32c of the side window frame member 32; and the profile element 34c and the internal element 34c of the bottom window frame member 34. The shield mounting bracket 32s is at Figure 7 and Figure 8 As can be seen in the figure, an internal shading device (not shown) can be mounted in the window frame 3 via a shading mounting bracket to provide shading for the pane 4.

[0118] Operating components and transport accessories- Figures 9 to 11b as well as Figures 36 to 39

[0119] 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.

[0120] First refer to Figure 9 The operating assembly 5 includes a window frame accessory 55, a main shaft portion 52 having a main shaft 521 and a handle 522 connected to the socket accessory 51 via a nut portion 53, the window frame accessory 55 connected to the bottom window frame member 34 in the installed state of the operating assembly, and the socket accessory 51 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.

[0121] In the illustrated embodiment, in which the roof window 1 defines a supply state suitable for packaging and shipping, the sash fitting 55 is connected to the bottom sash member 34 of the roof window 1 , while the spindle portion 52 and nut portion 53 and socket fitting 51 are provided separately from the roof window 1 .

[0122] The nut portion 53 comprises a nut ring 531 which is connected here by means of a set of bolts 532 to a set of flanges 512 protruding from a base plate 511 of the socket fitting 51 .

[0123] The operating assembly 5 also includes a strip 56 associated with the window frame fitting 55, which is capable of shifting between an active position and an inactive position, in which the strip 56 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 the inactive position is used to show a receiving gap between the flanges 552 of the window frame fitting 55.

[0124] The main shaft portion 52 includes an end portion 54 configured to mate with a window frame fitting 55 in an installed state.

[0125] Now also refer to Figure 39 , the end portion 54 of the main shaft portion 52 is provided with an opening 541 configured to cooperate with the strip 56 in the installed state.

[0126] The socket fitting 51 is provided with at least one guide protrusion 514 configured to be received in at least one corresponding guide hole 24 g of the bottom frame member 24 in the installed state of the operating assembly 5 .

[0127] like Figure 36 As shown in FIG, in the supply state of the roof window 1 , the transport fitting 57 is connected to the sash fitting 55 and the bottom frame member 24 , so that the sash 3 remains stable relative to the frame 2 .

[0128] Now also refer to Figure 37 and Figure 38 The transport fitting 57 comprises a base portion 571 configured to abut the inner side of the bottom frame member 24 and an anchoring portion 572 having an opening 573 which cooperates with the strip 56 associated with the window frame fitting 55 in the supply state of the roof window 1, and the anchoring portion 572 extends substantially perpendicularly to the base portion 570.

[0129] The transport fitting 57 includes an inclined portion 574 forming a transition between the base portion 571 and the anchor portion 572 .

[0130] In order to ensure correct positioning of the transport fitting 57 , in the supplied state of the roof window 1 , the base portion 571 is provided with at least one guide protrusion 575 cooperating with at least one corresponding guide hole 24 g of the bottom frame member 24 .

[0131] In order to maintain a stable relationship between the sash 3 and the frame 2 , the base portion 571 is provided with holes 576 configured to receive fastening means, such as screws, providing connection of the shipping fitting 57 to the bottom frame member 24 .

[0132] Connection unit- Figures 15 to 23

[0133] Hereinafter, the coupling unit 95 of the hinge assembly 9 will be described in some detail.

[0134] 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 hinge unit 91 will be described as including both the frame hinge base plate 921 and the frame hinge side flanges 924, and 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.

[0135] In order to make selective connection possible, the frame hinge part 92 is provided with coupling devices 926, 927 to cooperate with the top frame connecting plate 96 and the side frame connecting plate 97 respectively, so that the frame hinge base plate 921 of each hinge unit 91 of the hinge assembly 9 can be connected to the top frame connecting plate 96 and the frame hinge side flange 924 can be connected to the side frame connecting plate 97.

[0136] 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 bolt 961c on the base portion 961 and two bolt elements, engagement pins 962, 963, which also serve as engagement means for the top frame coupling plate 96. 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 milling portion 29a and a set of openings 29c, 29e, wherein the opening 29e is a through opening or through hole.

[0137] In the illustrated embodiment, the engagement means 926 of the frame hinge portion 92, which is provided on the frame hinge base plate 921, comprises a set of receiving recesses including two abutment recesses 926a, 926b that interact with corresponding engagement means on the top frame coupling plate 96 to align the hinge unit 91 relative to the coupling unit 95 in the longitudinal direction of the top frame member 21, preferably in the direction toward the inside and inward relative to the inner side of the top frame member 21, and also serve as a stop for the hinge unit 91. Here, the corresponding engagement means comprises two engagement pins 962, 963 that project inward relative to the base portion 961 and relative to the inner side of the top frame member 21.

[0138] Other engagement means of the top frame coupling plate 96 include a hook-shaped element 964 comprising an arm 964a with a hook-shaped piece 964b and connected to the base portion 961 by a swivel joint 964c. The hook-shaped element 964 is configured to cooperate with a corner portion 926d of a locking recess 926c formed in the frame hinge base plate 921 and forms part of a set of receiving recesses constituting the engagement means 926 of the frame hinge portion 92 to lock the hinge unit 91 relative to the coupling unit 95 in an outward direction.

[0139] The hook element 964 is biased toward a locked position in which the hook 964b is caught in the corner portion 926d of the locking recess 926c. Here, the bias is provided by a spring 964e, one end of which is received in a spring receiving opening 964d in the arm 964a and the other end is received in a spring receiving opening in the base portion 961, so that the spring 964e passes through the opening 961a, thereby allowing the spring 964e to move during the movement of the hook element 964 from the locked position to the unlocked position, in which the hook 964b is disengaged from the corner portion 926d.

[0140] The engagement means of the frame hinge portion 92 provided on the frame hinge side flange 924 is constituted by a secondary hinge pin 927 to lock the hinge unit 91 to the side frame member 22 in the first operating state and to allow the sash 3 to rotate in the second operating state.

[0141] By forming a connecting unit 95 having a top frame connecting plate 96 and a side frame connecting plate 97, the connecting unit 95 allows the frame hinge portion 92 of the associated hinge unit 91 to be selectively connected to the top frame connecting plate 96 and the side frame connecting plate 97 in a first operating state and to be connected only to the side frame connecting plate 97 in a second operating state.

[0142] The side frame coupling plate 97 includes a base portion 971 connected to the inner side of the side frame member 22, and the engagement means of the top frame coupling plate 96 includes a keyhole-shaped recess 971r in the base portion 971 of the side frame coupling plate 97. The keyhole-shaped recess is configured to cooperate with the secondary hinge pin 927 to engage and lock the hinge unit 91 to the side frame member 22 in the first operating state, and to allow the window frame 3 to rotate about the substantially horizontal second hinge axis β in the second operating state.

[0143] The secondary hinge pin 927 includes an enlarged head and a shaft, and the keyhole-shaped recess 971r includes an entry opening 971ra that allows the head of the secondary hinge pin 927 to enter and a narrow track portion 971rb that allows the shaft to enter but prevents the head of the secondary hinge pin 927 from being withdrawn. Figure 19 As shown in .

[0144] In order to guide the secondary hinge pin 927 into the keyhole-shaped recess, the access opening 971ra includes a recessed portion 971c.

[0145] Once the secondary hinge pin 927 has entered the keyhole-shaped recess 971r, it is locked by means of a biased locking element 972 on the side of the base portion 971 facing the inner side of the side frame member 22. The biased locking element 972 includes a connecting portion 972a and a resilient end portion 972b having an opening 972c, thereby allowing entry of the head of the secondary hinge pin 927. In order to release the locked engagement, the resilient end portion 972b is provided with a release protrusion 972d that can be manually manipulated.

[0146] The side frame coupling plate 97 is connected to 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 971f 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 milling 29b and a set of openings 29d, 29f.

[0147] Hinge assembly, second operating state and window frame mounting components - Figures 24 to 35

[0148] Now refer to Figures 24 to 35 The following describes possible movement modes and positions of the window frame 3 in the second operating state. Three positions will be described: a side coupling position, corresponding to the position where the window frame 3 with the hinge unit 91 is first coupled to the frame 2 due to engagement of the frame hinge side flange 924 with the side frame coupling plate 97; a top coupling position, corresponding to the position where the window frame 3 with the hinge unit 91 is ready to engage with the top frame coupling plate 96; and a working position where a gap is created between the top sash member 31 and the top frame member 21. It goes without saying that the window frame 3 can assume other positions in the second operating state.

[0149] In order to protect the components of the roof window 1 and to facilitate connection, a window frame mounting member 35 is provided which supports the window frame 3 during installation and use.

[0150] With particular reference Figure 29 The window frame mounting member 35 includes a body portion 351 , a frame engaging portion 352 and a plurality of supporting surfaces 353 , 354 , 356 for the window frame 3 .

[0151] In the illustrated embodiment, the window frame mounting member 35 includes three distinct bearing surfaces.

[0152] Among these support surfaces, the first support surface 353 supports the bottom sash member 34 at a side coupling position. Figures 24 to 28 The side connection position is shown in Figure 28The abutment between the first bearing surface 353 and the bottom sash member 34 is best shown in the cross-sectional view of FIG.

[0153] Figures 30 to 32 3 shows the second support surface 353 supporting the bottom sash member 34 in the top coupling position. As is apparent, the sash 3 has moved closer to the top frame member 31, and therefore, the hinge unit 91 is closer to the top frame coupling plate 96. In this position, the recesses 926a and 926b can be brought into engagement with the engagement pins 962 and 963, and the hook-shaped element 964 can be moved into engagement with the locking recess 926c until the hook 964b snaps into the corner 926d. If engagement is achieved, the roof window 1 is in its first operating state and can be used normally.

[0154] If the first operating state has been reached and the working position is desired, the hinge unit 91 is first disengaged from the top frame coupling plate 96 by releasing the hook element 964, for example by applying a suitable tool.

[0155] Once the disengagement has been carried out and the roof window 1 is in its second operating state, the sash mounting part 35 is arranged at the longitudinal end of the bottom frame member 24. In this way, the third support surface 356 can be allowed to support one or more side sash members 22, 23. In order to provide sufficient support, the portion of the sash mounting part 35 forming the third support surface 356 is wider than the body portion 351.

[0156] To ensure that the window frame mounting component 35 is securely held on the bottom frame member 24, the frame engaging portion 352 is shaped according to the contour of the bottom frame member 24 so that the dimensions of the engaging portion 352 match the contour and dimensions of the bottom frame member 23. In the illustrated embodiment, an inner contact portion 352a, a first inner contact portion 352b, a first outer contact portion 352c, a second inner contact portion 352d, and a second outer contact portion 352e are provided. In addition, an inner end portion 352f and an outer end portion 352g are provided.

[0157] Finally, the first support surface 353 is separated from the second support surface 354 by a separation rib 355 .

[0158] In the supplied state, two sash mounting parts 35 are suitably provided with the roof window 1. Although not preferred, support for the sash 35 can also be provided by a single sash mounting part 35, just as more than two sash mounting parts can be provided, for example in the case of wide roof windows.

[0159] Installation Method- Figures 40 to 50d

[0160] In the following, an exemplary method of installing a roof window 1 in a roof structure (not shown) will be described. It is understood that the various steps may be performed in a different manner or in a different order.

[0161] Figure 40 A roof window 1 is shown when installed in a roof structure (not shown) and in its normal use position, i.e., in a first operating state that allows the sash 3 to be opened relative to the frame 2. When installed, the roof window 1 is surrounded by an under-roof assembly and flashing assembly (not shown) that provides a weatherproof transition to the surrounding roof. Details of the configuration of this assembly are described in greater detail in the applicant's co-pending patent application filed on the same date as the present application.

[0162] In the following description, only the installation steps will be briefly described. For a detailed description of the interactions between the components, reference is made to the relevant parts in the above description of the embodiment.

[0163] In the supply state, a roof window 1 is provided having a frame 2, a window frame 3 and a window pane 4. Depending on the conditions at the installation site, the roof window 1 is usually supplied in the form of a package that is opened when approaching the building in which the roof window 1 is to be installed, or can be installed inside a room of the building. Figure 41a An example of an unpacking situation is shown in FIG. For easy handling of the window frame 3, a set of suction cup tools 36 is provided; however, it is also possible to manually operate the roof window 1 without tools or to lift the roof window with or without suction cup tools, see FIG. Figure 46 and Figure 47 .

[0164] It should be noted that in the embodiment shown, the insulating frame 7 is connected in the supplied state to the frame 2. However, the principle of the invention is also applicable to roof windows which are provided with an insulating frame 7 alone or without an insulating frame at all.

[0165] The operating assembly 5 is provided with only some parts fastened to the window frame 3, while other parts are provided separately. If a transport fitting 57 is present, this is removed.

[0166] After unpacking, the sash 3 is opened relative to the frame 2. Figures 41c to 41f As shown in FIG, the hinge unit 91 of the hinge assembly 9 is disengaged from the coupling unit 95 until the window frame 3 is disengaged from the frame 2.

[0167] The window frame 3 with the hinge unit 91 is placed in a suitable position awaiting further operations. This allows easy handling of the frame 2 and subsequent installation of the frame 2 in the roof structure. In preparation for installation, the mounting bracket 6 needs to be fastened to the frame 2.

[0168] Typically a set of mounting brackets 6 is provided separately, for example in a separate package within a roof window package. Figure 42 and Figure 43 As indicated in , each mounting bracket 6 is brought from its supply state into the mounted state.

[0169] Access to the frame 2 is then provided by swinging out sections of the insulating frame 7 to reveal the outer sides of the side frame members, as shown. Figure 44a Once the mounting bracket 6 has been installed, Figure 44b and Figure 44c By tightening as shown in FIG, the parts of the insulating frame 7 are repositioned, as shown in FIG. Figure 44d As shown in .

[0170] The frame 2 is installed by positioning the frame 2 in the opening provided and securing the mounting brackets 6 to the underlying roof structure. The under-roof components and flashing components are installed in the prescribed manner.

[0171] With the frame 2 in its proper position, the sash mounting members 35 are positioned on the bottom frame member and the sash 3 is lifted into the opening of the frame 2 to rest in one of the sash mounting members 35, as shown. Figure 45a The window frame 3 is placed in the side connection position on the window frame mounting member 35, as shown in FIG. Figure 45c , and each hinge unit 91 is engaged with a corresponding side frame coupling plate at each side of the frame 2 and the window frame 3, as shown in FIG. Figure 45d As indicated in .

[0172] The window frame 3 is then moved to the top coupling position on the window frame mounting member 35, as shown in FIG. 45 , and then each hinge unit 91 is engaged with the corresponding top frame coupling plate as shown in FIG. Figure 45f As shown in .

[0173] If the roof window 1 has been lifted to a position including the suction cup tool 36, as shown Figure 47 As shown in FIG, the window frame 3 can be placed in Figure 48b 36 from the interior of the building. Figure 48a , this operation requires disconnecting the hinge unit 91 from the top frame coupling plate of the coupling unit 95 and positioning the sash mounting component 35 at the end of the bottom frame member. Once the working opening between the frame and the sash has been established, the installer or other personnel can access the outside of the sash and remove the tools.

[0174] It will be appreciated that the working position may be established at any time during use of the roof window.

[0175] at last, Figures 49a to 49c and Figures 50a to 50d A series of pictures showing details of actual roof windows.

[0176] Alternative embodiments of the coupling unit - Figures 51 to 64

[0177] Hereinafter, some detailed description will be given of alternative embodiments of the coupling unit 95. Only the differences relative to the above-described embodiments will be described in detail. Elements having the same or similar functions as those in the above-described embodiments are represented by the same reference numerals. In some embodiments, a prime ' has been added to the reference numerals to identify corresponding elements.

[0178] like Figure 51 As shown in FIG, the operating assembly 5 comprises a handle 5'. Another difference from the above-described embodiment is that no glass bars are provided.

[0179] Now turn Figure 53 and Figure 54 As can be seen, the roof window 1 in the embodiment shown is provided with a lifting device 50 mounted on the frame 2 and interacting with the sash 3 .

[0180] exist Figure 55 and Figure 56 , details of an alternative embodiment of the articulation unit 91 are shown. Figure 13 and Figure 14 Compared to the embodiment of , it can be seen that the arm 9251 of the first opening limiter 925 of the alternative embodiment is rotatably connected to the window frame hinged side flange 934 by a rotatable joint 9252 at a lower position than in the previous embodiment. Figure 57 The function of the first opening limiter during the opening movement of the sash 3 relative to the frame 2 is shown in FIG.

[0181] As in the above embodiment, it is foreseeable that the hinge unit 91 is connected to the window frame 3 at the beginning of installation, and the connecting unit 95 is connected to the window frame 3 according to the embodiment. Figure 58 Connect to frame 2.

[0182] Furthermore, as in the above-described embodiment, 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 / or the adjacent side frame members 22, 23.

Alternative configurations are contemplated.

[0183] In order to make selective connection possible, the frame hinge part 92 is provided with a coupling device 926; 926', 927 to cooperate with the top frame connecting plate 96 and the side frame connecting plate 97 respectively, so that the frame hinge base plate 921 of each hinge unit 91 of the hinge assembly 9 can be connected to the top frame connecting plate 96, and the frame hinge side flange 924 can be connected to the side frame connecting plate 97.

[0184] Unlike the above-described embodiments, the engagement between the frame hinge portion 92 and the top frame coupling plate 96 allows for a stepwise engagement, i.e. one or more intermediate positions of the sash 3 relative to the frame 2 can be achieved during the coupling at the top. In the following, "intermediate position" means one or more such positions between the supply or installation state and the installed state.

[0185] In the following, it will be described how the coupling unit 95 and the hinge unit 91 are configured to assume the following positions relative to each other during installation of the roof window 1 :

[0186] i) intermediate position; and

[0187] ii) A final position, which corresponds to the installed state of the roof window.

[0188] exist Figures 59 to 60 、 Figures 61 to 62 and Figures 63 to 64 In the three embodiments shown in FIG, such two-step coupling includes engagement between coupling unit 95 and hinge unit 91 occurring at top frame member 21. It is also contemplated to include such a two-step coupling at side frame members 22.

[0189] These three embodiments will be described together where appropriate. Figures 59 to 60 The implementation method substantially corresponds to Figures 53 to 57 Reference numerals having the same or similar functions as those in the embodiment described above carry the same reference numerals. Only the differences with respect to the previously described embodiment and between the two embodiments will be described in detail.

[0190] Therefore, the top frame coupling plate 96 is here provided with coupling plate engagement means 964 ; 965 for cooperating with corresponding frame hinge part engagement means 926 ; 926 ′ of the frame hinge part 92 .

[0191] exist Figures 59 to 60 and Figures 61 to 62 In the embodiment, the connecting plate engagement means 964; 965 comprises two different engagement portions for cooperating with corresponding frame hinge portion engagement means 926; 926'.

[0192] As will be described, the link plate engagement means 964; 965 may be movable or fixed relative to the link plate 96, and the frame hinge engagement means 926; 926' may be fixed or movable.

[0193] Furthermore, the coupling plate engagement means is a female engagement means or a male engagement means, and the frame hinge portion engagement means is a male engagement means or a female engagement means.

[0194] In this way, it will be possible to provide a suitable combination of various types of engagement means to determine the intended function.

[0195] exist Figures 59 to 60 In the embodiment shown in FIG, the coupling plate engaging means comprises a hook-shaped element 964 comprising an arm 964a having a hook-shaped member 964b and connected to the base portion 961 at a swivel joint 964c. The frame hinge base plate 921 comprises a protrusion 926e constituting the frame hinge portion engaging means and configured to continuously cooperate with the intermediate engaging portion 964f and the final engaging portion 964g of said hook-shaped element 964.

[0196] The hook element 964 is hereby biased towards a locked position in which the protrusion 926e of the frame hinge base plate 921 engages the final engagement portion 964g. Figure 56 , showing how the bias is provided by a spring 964e, which is received at one end in a spring receiving opening 964d in the arm 964a and at the other end in a spring receiving opening in the base portion 961, the spring 964e passing through the opening 961a to allow the spring 964e to move during movement of the hook element 964.

[0197] exist Figures 59 to 60 Other details visible in FIG. 9 include corner portions 926 d of locking recesses 926 c formed in frame hinge base plate 921 .

[0198] exist Figure 59 In the position shown in FIG, the hinge unit 91 is arranged in an intermediate position relative to the top frame coupling plate 96. The intermediate position is a single intermediate position. As shown, the hook element 964 is caught on the protrusion 926e via the intermediate engagement portion 964f. The window frame 3 is now connected to the frame 2 in principle, but other configurations are conceivable.

[0199] In contrast, Figure 60In the position shown in , the sash 3 with the hinge unit 91 has been further pulled into the frame 2, and the hook element 964 has been rotated in the counterclockwise direction by the bias of the spring 964e. After this movement, the final engagement portion 964g is now engaged with the projection 926e. In order to achieve effective locking, the sash 3 may need to be "over-closed", that is, the sash 3 is pulled deeper into the frame 2 than the position it would have been in during normal operation. For this reason, the abutment recesses 926a, 926b are formed to have sufficient height to allow this operation. Releasing the engagement from the final position may also require this over-closing of the sash; this also provides additional safety against unintentional release.

[0200] exist Figures 61 to 62 In another alternative embodiment, the coupling plate engaging means 965 comprises a set of engaging pins 965a, 965b positioned at intervals in the height direction of the coupling plate 96. The frame hinge portion engaging means 926' comprises a locking protrusion 926a' having a track 926b' extending in the height direction of the frame hinge portion 96. Figure 61 The position in Figure 62 By comparing the positions in FIG. 9 , it can be seen how the track 926 b ′ is configured to continuously mate with the intermediate engagement pin 965 a and the final engagement pin 965 b.

[0201] The locking protrusion 926a' includes a fastening portion 926c' located at a first end portion of the locking protrusion 926a', in which the locking protrusion 926a' is fastened to a base portion 961 of the top frame coupling plate 96. A flange 926d' is formed at a second end portion opposite to the first end portion. The flange 926d' facilitates movement between an intermediate position and a final position. The flange 926d' can also be used to release the engagement. In the event of desired release engagement, for example, in order to disconnect the sash 3 from the frame 2, the sash 3 can be over-closed as described above.

[0202] exist Figures 63 to 64In another embodiment, the hook-shaped element 964 is provided with a plurality of indentations in the side facing the frame hinge part engagement device 926. The plurality of indentations constitute a continuous engagement portion. One or more of the indentations is formed by a curve that can be biased by a spring (not shown) to urge the hook-shaped element 964 in one direction, i.e., toward the final engagement position. However, the hook-shaped element 964 is not allowed to move backward away from the final engagement position. In this way, the plurality of indentations acts as a ratchet. In the illustrated embodiment, a first intermediate engagement portion 964h, a second intermediate engagement portion 964i, and a final engagement portion 964j are formed in the hook-shaped element 964 to cooperate with the protrusion 926e of the frame hinge part engagement device 926. In addition to ensuring a safe and reliable engagement operation, this embodiment has the additional advantage of reducing friction and further minimizing the effects of inevitable manufacturing tolerances in the roof window 1.

[0203] Although not described in detail for alternative embodiments, the engagement means of the frame hinge portion 92 provided on the frame hinge side flange 924 is constituted by a secondary hinge pin 927 to lock the hinge unit 91 to the side frame member 22 in the first operating state and to allow the window frame 3 to rotate in the second operating state.

[0204] By forming each connecting unit 95 to have a top frame connecting plate 96 and a side frame connecting plate 97, the connecting unit 95 allows the frame hinge portion 92 of the associated hinge unit 91 to be selectively connected to the top frame connecting plate 96 and the side frame connecting plate 97 in a first operating state and to be connected only to the side frame connecting plate 97 in a second operating state.

[0205] The side frame coupling plate 97 comprises an opening (not shown in detail) intended to cooperate with the secondary hinge pin 927 to engage and lock the hinge unit 91 to the side frame member 22 in a first operating state and to allow the window frame 3 to rotate about a second, substantially horizontal hinge axis β in a second operating state.

[0206] In the following, an exemplary method of installing a roof window 1 in a roof structure (not shown) will be described. It is understood that the various steps may be performed in a different manner or in a different order.

[0207] In the supplied state, a roof window 1 is provided with a frame 2, a sash 3, and a window pane 4. Depending on the conditions at the installation site, the roof window 1 is typically supplied in a package that is opened upon approaching the building, where the roof window 1 is to be installed, or can be installed inside a room. To facilitate manipulation of the window frame, a set of suction cup tools may be provided; however, the roof window 1 can also be manipulated manually without tools or lifted with or without the suction cup tools.

[0208] It should be noted that in the embodiment shown, the insulating frame 7 is connected in the supplied state to the frame 2. However, the principle of the invention is also applicable to roof windows which are provided with an insulating frame 7 alone or without an insulating frame at all.

[0209] After unpacking, the window frame 3 is opened relative to the frame 2. The hinge unit 91 of the hinge assembly 9 is disengaged from the coupling unit 95 until the window frame 3 is disengaged from the frame 2, that is, .... Figure 58 The location shown in .

[0210] The window frame 3 with the hinge unit 91 is placed in position awaiting further manipulation. This allows easy handling of the frame 2 and subsequent installation of the frame 2 in the roof structure. In preparation for installation, the mounting bracket 6 is fastened to the frame 2.

[0211] Installation of the frame 2 is carried out substantially as described above by positioning the frame 2 in the opening provided and securing the mounting brackets 6 to the underlying roof structure.

[0212] In summary, the components of the roof window are easily dismantled and each component can in principle be reused, recycled or the material recovered for other uses by appropriate environmentally responsible disposal means.
