DESCRIPTION OF EMBODIMENTS

[0029] In the following, embodiments of the inventive hinge and window will be described in further detail, with reference to a window with a prior art hinge 10 is shown in FIG. 1. Such a hinge 10 and other parts of the window which are applicable also to a window according to the invention are described in Applicant's published European patent applications EP 2 770 146 A1 and EP 2 770 149 A1 to which reference is hereby explicitly made. It is hence to be understood that the hinge and mounting arrangement according to the invention replaces the prior art hinge 10 at one or both sides of the window.

[0030] In a manner known per se, the window comprises a sash 2 carrying a glazing in the form of a pane 3 and a frame 1. The window is intended to be built into a surface, which is inclined with respect to the horizontal, typically a roof, and the window will in the following be referred to as roof window. At a position between the top and centre of the window, there is a hinge connection between the frame 1 and the sash 2. The hinge connection in FIG. 1 comprises a set of two prior art hinges, of which one hinge 10 is visible. The frame 1 and sash 2 is each formed by four members of which one frame side member la and one sash side member 2a are indicated. The sash 2 is openable with respect to the frame 1, as the sash 2 may be moved from a closed position, in which e.g. the sash side member 2a is substantially parallel with the frame side member 1a, to an open position, in which the sash side member 2a forms an angle with the frame side member 1a. During this movement the sash 2 rotates about a hinge axis situated at the hinge connection. As indicated in FIG. 1, the hinge axis is located between a centre axis and the top of the roof window, preferably in the interval to of the distance between the centre axis and the top, most preferred substantially at of the distance between the centre axis and the top. Other positions of the hinge axis are of course conceivable, for instance at the centre of the roof window. A corresponding operation of the window as described above and from here on is also true for the type of hinge described in the Applicant's co-pending international application published under WO 2017/076416 A1. Common to the hinge types applicable in such windows is that a number of movement supporting parts are provided in the hinge, as will be described further below.

[0031] To protect the interior and the components of the window itself and to ascertain weather-proof transition to the surrounding roofing, the roof window comprises a covering, including flashing members (not shown), cladding and covering elements of which a frame side covering element 1b and sash side covering element 2b are shown.

[0032] From a closed position, the user operates the operating device of the window. The operating device typically comprises a handle (not shown) connected with the sash bottom member and/or an operating and locking assembly including a ventilation flap at the sash top member with a lock mechanism to interact with a striking plate on the frame top member. The hinge 10 exerts a moment on the sash 2, and in combination with the force, and hence moment, exerted by the user operating the operating device, the moment resulting from the weight of the sash 2 and pane 3 is overcome, along with any frictional forces present. All in all, the opening operation entails that the sash 2 is moved from a closed position to an open position as represented by FIG. 1, in which the sash plane forms an opening angle with the frame plane. Closing the window from the open position entails the opposite movement of the sash 2. It is possible to position the sash 2 in a number of arbitrary opening positions, in which the sash 2 is held stable relative to the frame 1. The sash 2 is also able to be rotated substantially through 180 to allow cleaning of the outside of the pane 3 from the inside of the building in which the roof window is installed.

[0033] Referring now to FIGS. 2 to 6, a first embodiment of a hinge 110 according to the invention will be described in detail.

[0034] When referring to the Figures, the terms up, down, upwards, downwards, top and bottom are taken relative to how the figures are displayed, that is having the frame arranged in a lying position with the covering elements facing upwards. A front view is taken from the hinge and viewing towards the frame. A view from behind is therefore taken as viewed from the frame towards the hinge. A longitudinal direction is, if nothing else is mentioned, longitudinal along the length of the frame member. It is to be understood that the arrangement shown in a horizontal orientation is not the normal orientation as the window is installed in an inclined roof.

[0035] In FIG. 2, the hinge 110 is shown in a position corresponding to an initial step of an installation process. This position also corresponds to a supply condition of the hinge according to the invention. The hinge 110 comprises a frame hinge part 130 and a sash hinge part 140 configured to assume an angle relative to the frame hinge part 130. The hinge 110 forms part of a set of hinges, of which the frame hinge part 130 of each hinge 110 is configured to be connected to the frame side member 1a of the frame 1 of the roof window in a mounted condition by a mounting arrangement to be described in further detail, at a location chosen to provide the desired position of the hinge axis , and the sash hinge part 140 is correspondingly configured to be connected to the sash side member 2a.

[0036] As in the prior art hinge 10, the base plate 135 of the frame hinge part 130 defines a hinge plane substantially perpendicular to the hinge axis of the window in the mounted condition of the hinge, the base plate 145 of the sash hinge part 140 being substantially parallel to the base plate 135 of the frame hinge part 130. The hinge 110 moreover comprises a plurality of movement supporting parts 190, connected to a respective base plate 35, 45 of the frame hinge part 130 and the sash hinge part 140, and configured to allow the sash hinge part 140 to assume an angle relative to the frame hinge part 130. In the specific embodiments shown and described, the movement supporting parts 190 comprises a linkage mechanism including links, springs and at least one pick-up element to provide the hinge as a pantograph hinge. For a description of the parts and operation of such a pantograph hinge, explicit reference is hereby made to the embodiment shown in and described in relation to FIGS. 2 to 5 of the above-mentioned WO 2017/076416 A1. In principle, however, the fundamental principles of the invention are also applicable to traditional pivot hinges including an arc-shaped guidance on the frame hinge part to receive an arc-shaped slide on the sash hinge part.

[0037] A mounting arrangement generally designated 150 comprises a mounting plate 151 which is shown in the position it will take in the mounted condition of the hinge on the frame side member 1a with fastening means which can be for example pins or spigots (not shown in this embodiment, cf. second embodiment), or any type of threaded fastening means. The spigots are configured to be arranged in corresponding holes 173, 174 on the mounting plate 151. Preferably, the spigots are arranged such that they end in flush with an outer surface 151a of the mounting plate 151 in order to avoid collision with the components of the frame hinge part 130. The outer surface 151a is the surface of the mounting plate 151 that faces away from the frame side member 1a, an inner surface 151b facing the frame side member 1 a in the mounted condition. The base plate 145 of the sash hinge part 140 is provided with corresponding spigots (not described in detail).

[0038] The remaining components of the hinge 110 shown in FIG. 2, i.e. the base plate 135 of the frame hinge 1 part 30, the movement supporting parts 190 and the sash hinge part 140 with its base plate 145, are in a position corresponding to that the sash (not shown) would have in this initial step of installation, namely substantially vertical. This position also corresponds to the supply condition of the hinge on the window, in which these remaining components are all connected to the sash. Hence, in the supply condition, only the mounting plate (or mounting plates, if more than one) of the hinge is fastened to the frame.

[0039] This initial step is common to the first embodiment, the second embodiment (cf. FIG. 7) and further embodiments. Elements having the same or analogous function as in the first embodiment are provided with the same reference numerals to which 100, 200, 300 and 400, respectively, have been added. The operational principles underlying the invention are thus based on the following fundamental features, referring now jointly to FIGS. 2 and 7, and described referring only to the first and second embodiments:

[0040] The mounting arrangement 150; 250 has one or more mounting plates 151; 251, 252 arranged on the frame member 1a substantially in parallel to the base plate 135; 235 of the frame hinge part 130; 230 in the mounted condition. At least one set of coupling means 153, 154: 253, 254 is configured to engage with corresponding coupling means 163, 164; 263, 264 of the remaining components of the set of components of the hinge 110; 210. The coupling means of the mounting arrangement 150; 250 comprise at least one reception member 153, 154; 253, 254 provided on the at least one mounting plate 151; 251, 252 to engage with a respective engagement member 163, 164; 263, 264 of the coupling means of the remaining components by movement of the remaining components of the hinge substantially in parallel with said hinge plane to provide a releasable connection between the remaining components of the hinge 110; 210 and the at least one mounting plate 151; 251, 252.

[0041] In all shown embodiments, a first engagement member of the coupling means of the remaining components of the hinge is a bolt 163; 263 provided on the base plate 135; 235 of the frame hinge part 130; 230, and a first reception member is a slot 153; 253 in one of the mounting plates 151; 251 adapted to receive the bolt 163; 263. It is preferred that from the position shown in FIGS. 2 and 7, the remaining components of the hinge are moved downwards and the bolt 163; 263 is first slid into the slot 153; 253. Subsequently the base plate 135; 235 of the frame hinge part 130; 230 and the other remaining components of the hinge 110; 210 are rotated about the bolt 163; 263 to provide an at least temporary retention of the remaining components of the hinge relative to the at least one mounting plate 151; 251.

[0042] It is noted that during the entire movement, the respective planes of the mounting plate and the base plates of the frame hinge part and the sash hinge part are at all times kept substantially parallel, thus avoiding transverse movements perpendicular to the hinge plane as defined by the base plate 135; 235 of the frame hinge part 130; 230.

[0043] Following the engagement of the coupling means of remaining hinge components with the coupling means of the mounting arrangement as described in the above, the window sash is in safe position, as the weight of the sash is transferred to the frame via the mounting arrangement. The installer is thus in principle free to leave the window at least temporarily.

[0044] An increased security against unintentional release is however increased if also a secondary coupling is present.

[0045] According to the invention, and as shown in connection with the first and second embodiments, a second engagement member of the coupling means of the remaining components comprises a shoulder portion 164; 264, and the second reception member of the coupling means of the mounting arrangement 150; 250 comprises a spring-biased latch element 154; 254 provided with an abutment portion 155; 255 to engage with said shoulder portion 164; 264 in the mounted condition.

[0046] As shown, the spring-biased latch element 154; 254 is here connected to the mounting plate in question, the mounting plate 151 in the first embodiment, and a second mounting plate 252 in the second embodiment, in a pivotal connection 159; 259.

[0047] The spring-bias of the latch element 154; 254 is specifically provided by a leaf spring 156; 256 and the latch element 154; 254 includes a spring engagement portion 157a; 257a. As shown in detail only in connection with the second embodiment, the leaf spring 256 is received in a spring pocket 256a of the second mounting plate 252. Other means of accommodating the leaf spring are conceivable.

[0048] The provision of the spring-biased latch element 154; 254 ensures a simple, precise and reliable secondary coupling between the remaining hinge components and the mounting arrangement such that the releasable connection is achieved in a semi-automatic step when rotating the sash relative to the frame during installation.

[0049] In order to be able to release the engagement in an easy manner, the spring-biased latch element 154; 254 in the specific first, second and third embodiments includes a tongue portion 157b; 257b acting as a handle for release of the releasable connection.

[0050] A further detail of the latch element 154; 254 is the presence of a guide portion 157c; 257c. The guide portion 157c; 257c is particularly useful during installation, i.e. activation of the releasable connection, and when releasing the connection.

[0051] Although the releasable connection is thus achieved without the need for carrying out additional steps to secure the sash to the frame, an additional locking device may be incorporated in the hinge or mounting arrangement. It is conceivable to utilise parts of the window covering for locking the set of hinge components relative to each other in the mounted condition of the hinge. Examples of locking devices are conceivable to the person skilled in the art.

[0052] One difference between the first and second embodiments is that in the second embodiment, the mounting arrangement 250 comprises a first mounting plate 251 and the second mounting plate 252 mentioned above. Referring also to the above description, it is apparent that the first reception member 253 is positioned in the first mounting plate 251 and the second reception member in the form of spring-biased latch element 254 is associated to the second mounting plate 252.

[0053] Another difference is that the second mounting plate 252 comprises a cover portion 258 ensuring that the operational parts of the mounting arrangement are hidden to the user. In principle, the only exception is the tongue portion 257b acting as a handle for release of the connection which is accessible to the user. It is noted that the provision of a cover portion is also conceivable in connection with the first embodiment.

[0054] The fastening of the respective mounting plates 251, 252 to the frame side member is ensured in substantially the same way as with the one-piece mounting plates of the first embodiment, namely via spigots 271a, 271b on the first mounting plate 251, and spigots 272a, 272b on the second mounting plate 252. Only holes 273, 274 in the first mounting plate 251 for spigots 271a, 271b are shown. It is for instance conceivable to form the second mounting plate 252 in one-piece as a moulded part of a suitable plastic material, including the cover portion 258 and the spigots 272a, 272b.

[0055] Referring now to FIGS. 15 and 16, details of a third embodiment of a hinge generally designated 310 are shown. Only differences relative to the first and second embodiments will be described in detail.

[0056] As in previously described embodiments, the hinge 310 comprises a mounting arrangement 350 comprising a mounting plate 350 in which a first reception member in the form of slot 353 is provided. A second reception member in the form of latch element 354 is provided as well.

[0057] Spring 356 for biasing the latch element 354 extends from under the latch element 354 to a hook-up section at a spring engagement protrusion 351a on the mounting plate 351a.

[0058] A cover 358 is provided as well, configured to be connected to the mounting plate 351 by means of first and second engagement means 358b, 358c to engage with first and second cover engagement protrusions 351b, 351c on the mounting plate 351. As is furthermore apparent, the cover 358 has a first spring abutment portion 358a and a second spring abutment portion 358d.

[0059] As a further detail, reference is initially made to FIGS. 4 and 8, in which the connection of the frame side covering element 1b and sash side covering element 2b to the respective hinge 110, 210 is carried out by a snap connection 160, 170; 260, 270. The snap connection typically comprises a snap anchor fastened to the covering element 1b, 2b and a holding clip formed in the relevant hinge part. An advantageous version of the snap anchor will be described in more detail below with reference to FIGS. 15 to 20.

[0060] In the first embodiment, it is noted that the snap connection 170 for connecting the covering element 1b to the hinge 110 is located on the mounting plate 151. In the second embodiment, the snap connection 270 for connecting the covering element 1b to the hinge 210 is located on the base plate 235 of the base plate 230.

[0061] In the following, it will be described in more detail how a snap connection 470 is carried out by introducing a snap anchor 80 connected to the covering element 1b into a holding clip 90 connected to a hinge generally designated 410.

[0062] The snap anchor 80 is generally pre-mounted onto the covering element 2b, 1b and the covering element may subsequently, after installing the hinge 410, be snapped in place. Referring back to FIG. 1, in which it also emerges how the frame side covering element 1b and sash side covering element 2b interact with each other, it is noted that the movement pattern of the hinge allows that the sash side covering element 2b is able to be retracted from its position under the frame side covering element 1b during the opening movement of the sash 2 relative to the frame 1, and conversely, be inserted under the frame side covering element 1b at the final stage of the closing movement.

[0063] Referring now to FIGS. 17 to 22, detailed views of the snap connection 470 are illustrated. Only the snap connection 470 of the frame hinge part of the hinge 410 will be described. Generally, the snap connection of the sash hinge part may be identical. In that way, the same snap anchor 80 can be used on either of the holding clips 90. The snap anchor 80 is thus connected to the covering arrangement 1b, 2b and configured for releasable connection directly to a respective holding clip 90 integral with the hinge 10 and arranged to receive the respective snap anchor 80.

[0064] Each holding clip 90 comprises a receiving portion 91 and an anchor engagement portion 92. The receiving portion 91 of the holding clip 90 is here substantially U-shaped and comprises two opposing supporting surfaces 93 extending between a respective upper end surface 95 and the anchor engagement portion 92. Introduction of the snap anchor 80 into the holding clip 90 is facilitated if at least one of the opposing surfaces 93 is provided with a rounded edge 94 at the transition between the respective upper end surface 95 and the supporting surface 93. The holding clip 90 furthermore has a front side 90a and a back side 90b.

[0065] The anchor engagement portion 92 of each holding clip 90 is in the embodiment shown formed as an offset section comprising at least one side surface 96 and a lower end surface 97. Here, there are two symmetrically arranged side surfaces 96 to end in the lower end surface 97, and the offset section has a front surface 98a, a back surface 98b and also an inclined upper surface 99.

[0066] Turning now to a description of preferred embodiments of the snap anchor with further reference to FIGS. 15 to 20, the snap anchor 80 comprises a top surface 85 configured to abut a lower side of the respective covering element 1b, 2b, a guide portion 81 and an engagement portion 82.

[0067] The guide portion 81 of the snap anchor 80 comprises two opposing guide surfaces 83 to interact with the two opposing supporting surfaces 93 of the receiving portion 91 of the holding clip 90. In order to facilitate the mounting process, each guide portion 81 may as shown be provided with a rounded lower edge 81a. Furthermore, and in particular for improving the retention of the snap anchor 80 in the holding clip 90, a protruding side wall portion 81b is also provided at both sides of the guide portion 81.

[0068] The engagement portion 82 comprises a tongue 88 and two legs 87 extending from the top surface 85 of the snap anchor 80 and meeting in a lower point 87a such that a slot 89 is formed between the legs 87 and the tongue 88. The tongue 88 is in the embodiment shown formed integral with the guide portion 81 of the snap anchor 80 and has a central aperture 88a. The central aperture 88a is present in order to facilitate the manufacturing process.

[0069] The engagement between the engagement portion 82 of the snap anchor 80 and the anchor engagement portion 92 of the holding clip 90 is performed in that the slot 89 of the engagement portion 82 of the snap anchor 80 surrounds the anchor engagement portion 92 of the holding clip 90 in the mounted condition.

[0070] In the mounted condition, a back surface 88b of the tongue 88 abuts the front surface 98a of the offset section of the anchor engagement portion 92 of the holding clip.

[0071] The legs 87 of the snap anchor 80 are pre-formed with a bias in a direction away from the tongue 88.

[0072] Furthermore, the snap anchor 80 comprises at least one resilient arm 86, here two resilient arms 86, connected at a transition portion 86a to the top surface 85 of the snap anchor 80 and having a free end portion 86b. As shown, the resilient arms 86 are in the embodiment shown located at a lower level than the top surface 85.

[0073] When mounting the covering elements 1b, 2b to which the snap anchors 80 have been connected, the snap anchor 80 is introduced into the holding clip 90 as indicated in the above and moved downwards in the receiving portion 91. In order to attain the releasable connection, the engagement portion 82 is moved further downwards until the lower part of the slot 89 is located below the lower end surface 97 of the offset section of the anchor engagement portion 92.

[0074] In the snap connection, a slight play is necessary in order to allow the slot 89 of the engagement portion 82 of the snap anchor 80 to be guided over the anchor engagement portion 92. Furthermore, unavoidable tolerances in the parts of the hinge including the holding clip 90, and in the snap anchor 80 itself, make it advantageous to incorporate resilient means into the connection. Such resilient means may take any suitable form, but here the required play and any tolerances are accommodated by the presence of the resilient arms 86 at the top surface 85 of the snap anchor 80. Once the engagement portion 82 has been brought into engagement with the anchor engagement portion 92, the free end portions 86a of the resilient legs 86 come into contact with the respective upper end surface 95 of the holding clip 90. When the resilient legs 86 bend, the relative movement will in turn pull the legs 87 upwards and thereby ensure abutment between the lower point 87a with the lower end surface 97 of the anchor engagement portion 92 of the holding clip 90.

[0075] In the mounted condition, and in the case of a pulling force acting on the associated covering element, either as a mechanical force when handling the window or due to wind load, the configuration of the snap anchor 80 will support the snap engagement and prevent unwarranted release from the holding clip 90 of the hinge 10.

[0076] As a first measure to retain the snap engagement, this is obtained by the fact that a tensional load transmitted via the symmetrically arranged legs 87 gives rise to substantially radial reaction forces having as their centre a position in the offset section of the anchor engagement portion 92 defined by radius of curvature of the side surfaces 96 and the lower end surface 97 of the anchor engagement portion, thereby reducing stress caused by moment to an absolute minimum, leaving only tension stress in legs 87 and lower point 87a

[0077] A further factor contributing to enforcing the snap engagement in the mounted condition is the configuration of the legs 87 with a pre-formed bias to force the legs 87 as close to the centre of the snap anchor 80 as possible. In this manner, the respective line of action of a pulling force acting substantially centrally in the snap anchor 80 on one hand and the reaction force between the legs 87 and lower point 87a with the anchor engagement portion 92 on the other will be located close to each other and hence the resulting moment will be minimized. Optimally, the lines of actions coincide.

[0078] Finally, stability of the snap anchor 80 in the holding clip 90 and in turn of the associated covering element 1b is provided by the arrangement of suitable abutment surfaces between back sides of the legs 87 and front sides 90a of the holding clip 90 and between the protruding side wall portions 81b of the guide portion 81 and the back sides 90b of the holding clip 90. In an optimal configuration, these abutment surfaces are all plane and parallel to each other; however, this may be difficult to obtain in practice due to for instance practical considerations during moulding of the snap anchor 80. A sufficient stability is obtained if only opposing abutment surfaces are present though.

[0079] In case it is for some reason desirable to dismount the covering element from the hinge, release of the snap engagement is particularly easy as the snap anchor 80 as in the shown embodiment comprises a grip portion 84 formed at the ends of the legs 87 opposite the top surface 85.

[0080] The connection between the snap anchor and the covering element 1b, 2b may in principle be carried out in any suitable manner, including introducing a fastening element such as a screw or rivet into an opening in the top surface of the snap anchor. Such a rivet would be for instance a blind or pop rivet on the covering element 1b, 2b, further provided with an external thread to engage the opening in the snap anchor. Alternatively, or additionally, the snap anchor could be connected to the covering element 1b, 2b by an adhesive connection, this renders the presence of fastening means such as a screw or rivet redundant, and the snap anchor is so to say integral with the covering element. As a further alternative, the snap anchor may be connected to the covering element as described in Applicant's published WO 2018/077367 A1.

[0081] It is to be understood that the locking and the mounting may differ depending on the specific installation and the specific hinge. The hinge with mounting arrangement described may also be suitable for any window, including roof windows at any inclination and facade windows of any size. Also some different shapes when possible to use a hinge as the one described.

[0082] It should be noted that the above description of preferred embodiments serves only as an example, and that a person skilled in the art will know that numerous variations are possible without deviating from the scope of the claims.
