- the sash 2 rotates about a hinge axis ⁇ situated at the hinge connection.
- the hinge axis ⁇ is located between a centre axis and the top of the roof window, preferably in the interval 1/3 to 2/3 of the distance between the centre axis and the top, most preferred substantially at 1/2 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.
- hinges that the invention is applicable to include pivot hinges are for instance disclosed in Applicant's EP 1 038 083 B1 and EP 1 781 883 B1 , which are very versatile as regards operational areas and adaptation of components. Examples of roof windows incorporating such adapted hinges are shown in Applicant's published European patent applications EP 2 770 146 A1 and EP 2 770 149 A1 . 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.

Abstract
Description
- The present invention relates to a roof window having a frame and a sash, comprising a set of hinges, each hinge including a frame hinge part and a sash hinge part configured to assume an angle relative to the frame hinge part, a covering arrangement including a frame side covering element and a sash side covering element arranged to cover at least said hinge, and a hinge and covering assembly for mounting the covering arrangement on the hinge including at least one snap connection. The invention furthermore relates to a method of providing a hinge and covering assembly.
- Basically, roof windows may be provided in a number of varieties and include more or less complicated structures in order to allow opening of the sash and to fulfil other functions, such as ventilation, while permitting cleaning of the outside of the pane from inside the building. The varieties include roof windows of the pivoting type, the hinge axis being either located at the centre or displaced from the centre of the window, and top-hung roof windows that pivot for cleaning by means of an intermediate frame.
- These requirements are made possible by the provision of a hinge with a particular pattern of movements, which in turn makes it possible to establish an overlap between the covering element fastened to the frame and the counterpart covering element fastened to the sash in the closed position of the roof window. In such a hinge, the covering elements thus generally comprise at least two parts, one for covering the sash hinge part and one covering the frame hinge part. The covering elements are designed to protect the hinge and interior parts of the window from amongst other things weather, dirt and grime, since this may cause the hinge to rust and in worst case cause the window to leak rain water and thereby possibly cause damage. The two covering elements are designed to allow an angular motion relative to each other, while opening and closing the window. During installation of the window, it is often necessary to disassemble the covering elements from the window in its supply condition and then connect them again, thus requiring several steps. In prior art roof windows, the covering elements are most often attached by fastening the covering element onto the corresponding parts of the hinge, or the frame or sash itself, by fastening elements such as screws.
- One example of a roof window incorporating an improved fastening means is shown in Applicant's
EP 2 751 354 B1WO 2013/050043 A1 , corresponding to the closest prior art, andEP 2507588 A2 . - Common to the above-mentioned fastening solutions is that they affect the surface of the covering elements, either in the form of an aperture to receive the screw, or by the rivet holding the male part, which makes it challenging to provide the desired finishing. Furthermore, the connection between the male and female fastening means, and to the hinge itself, may be cumbersome, leaving room for improvement.
- With this background it is an object of the present invention to improve a roof window with respect to manufacturing and installation conditions.
- In a first aspect, this and further objects are met by the provision of a roof window of the kind mentioned in the introduction which is furthermore characterised in that the snap connection of the hinge and covering assembly comprises at least one snap anchor connected to the covering arrangement and configured for releasable connection directly to at least one holding clip integral with the hinge and arranged to receive said at least one snap anchor.
- This is an advantage since the mounting procedure of the covering arrangement is rendered considerably faster than if the covering arrangement would be fastened by additional fastening elements. Also, the manufacture and factory assembly of the roof window is facilitated, as the snap anchor replaces both the plastic fitting connected to the hinge and the male part of the snap connection of the prior art arrangement. The snap anchor thus has more built-in functionalities. In this way, a snap anchor may be pre-mounted onto a covering element in advance and snapped in place when the hinge has been installed. A hinge and covering assembly of this type may be formed in any suitable way to fit the specific covering arrangement and hinge to be used. The other components of the hinge with an integral holding clip may be of a kind featured in Applicant's co-pending application with the same filing date as the current application, although the hinge and covering assembly may be adaptable to basically any type of hinge to improve installation of the covering elements, as long as the hinge is modified accordingly. Finally, the need for tools and additional elements while installing the covering arrangement is reduced.
- In a second aspect, a method of providing a hinge and covering assembly in a roof window having a frame and a sash is provided.
- Other presently preferred embodiments and further advantages will be apparent from the following detailed description and the dependent claims.
- The invention will be described in more detail below by means of non-limiting examples of embodiments and with reference to the schematic drawing, in which

Fig. 17 is a partial perspective and break-out view of the still further embodiment hinge and covering assembly ofFig. 16 . - In a manner known per se, the window comprises a
sash 2 carrying a glazing in the form of apane 3 and aframe 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 theframe 1 and thesash 2. The hinge connection inFig. 1 comprises a set of two prior art hinges, of which one hinge 10' is visible. Theframe 1 andsash 2 is each formed by four members of which oneframe side member 1 a and onesash side member 2a are indicated. Thesash 2 is openable with respect to theframe 1, as thesash 2 may be moved from a closed position, in which e.g. thesash side member 2a is substantially parallel with theframe side member 1 a, to an open position, in which thesash side member 2a forms an angle with theframe side member 1 a. During this movement thesash 2 rotates about a hinge axis α situated at the hinge connection. As indicated inFig. 1 , the hinge axis α is located between a centre axis and the top of the roof window, preferably in theinterval 1/3 to 2/3 of the distance between the centre axis and the top, most preferred substantially at 1/2 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. - The same operation as described above and from here on is also true for the type of hinge described in the Applicant's pending Danish patent application No.

All in all, the opening operation entails that thesash 2 is moved from a closed position to an open position as represented byFig. 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 thesash 2. It is possible to position thesash 2 in a number of arbitrary opening positions, in which thesash 2 is held stable relative to theframe 1. Thesash 2 is also able to be rotated substantially through 180° to allow cleaning of the outside of thepane 3 from the inside of the building in which the roof window is installed. - 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 1 b' and sashside covering element 2b' are shown.

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 direction longitudinal is, if nothing else is mentioned, longitudinal along the length of the frame. It is to be understood that the arrangement shown in a horizontal orientation is not the normal orientation as the window is installed.
- The
hinge 10 comprises aframe hinge part 100 and asash hinge part 200 configured to assume an angle relative to theframe hinge part 100. Thehinge 10 forms part of a set of hinges, of which theframe hinge part 100 of eachhinge 10 is configured to be fastened to theframe side member 1 a of theframe 1 of the window at a location chosen to provide the desired position of the hinge axis α, and thesash hinge part 200 is correspondingly configured to be fastened to thesash side member 2a. Theframe hinge part 100 comprises abase plate 110 and the sash hinge part 200 abase plate 210. Fastening of the hinge to the respective frame and sash side members may take place in any suitable manner, for instance as in Applicant's co-pending patent application having the same filing date as the present application. - As seen in

This operation may save a lot of time to the installer, as well as the need for loose fastening elements is eliminated. Referring back toFig. 2 , in which it also emerges how the frameside covering element 1 b and sashside covering element 2b interact with each other; a crankedportion 2c of the sashside covering element 2b ensures a tight and flush transition between the sashside covering element 2b and the frameside covering element 1 b in the closed position of the roof window. At the same time, the movement pattern of the hinge allows that the sashside covering element 2b is able to be retracted from its position under the frameside covering element 1 b during the opening movement of thesash 2 relative to theframe 1, and conversely, be inserted under the frameside covering element 1 b at the final stage of the closing movement. - Referring now to
Figs 4 to 7 , detailed views of asnap connection Fig. 4 shows asnap connection 70 of thebase plate 110 of theframe hinge part 100. Generally, thesnap connection 60 may be identical on thesash hinge part 200, and therefore a view of any of thesnap connections same snap anchor 80 can be used on either of the holding clips 90. However, thesnap connections snap anchor 80 is thus connected to thecovering arrangement respective holding clip 90 integral with thehinge 10 and arranged to receive therespective snap anchor 80.

Thetongue 88 is in the embodiment shown formed integral with theguide portion 81 of thesnap anchor 80 and has acentral aperture 88a. Thecentral aperture 88a is present in order to facilitate the manufacturing process. The engagement between theengagement portion 82 of thesnap anchor 80 and theanchor engagement portion 92 of the holdingclip 90 will be described with particular reference toFigs 12 and 13 , of whichFig. 13 is a partial perspective view on a larger scale. - As shown, the
slot 89 of theengagement portion 82 of thesnap anchor 80 surrounds theanchor engagement portion 92 of the holdingclip 90 in the mounted condition shown inFig. 13 . - In the mounted condition, a
back surface 88b of thetongue 88 abuts thefront surface 98a of the offset section of theanchor engagement portion 92 of the holding clip. - In the embodiment shown and described, the
legs 87 of thesnap anchor 80 are pre-formed with a bias in a direction away from thetongue 88. - Furthermore, the
snap anchor 80 comprises at least oneresilient arm 86, here tworesilient arms 86, connected at atransition portion 86a to thetop surface 85 of thesnap anchor 80 and having afree end portion 86b. As shown, theresilient arms 86 are in the embodiment shown located at a lower level than thetop surface 85. - When mounting the
covering elements snap anchor 80 is introduced into the holdingclip 90 as indicated in the above and moved downwards in the receivingportion 91. In order to attain the releasable connection, theengagement portion 82 is moved further downwards until the lower part of theslot 89 is located below thelower end surface 97 of the offset section of theanchor engagement portion 92. - In the snap connection, a slight play is necessary in order to allow the
slot 89 of theengagement portion 82 of thesnap anchor 80 to be guided over theanchor engagement portion 92. Furthermore, unavoidable tolerances in the parts of the hinge including the holdingclip 90, and in thesnap 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 theresilient arms 86 at thetop surface 85 of thesnap anchor 80. Once theengagement portion 82 has been brought into engagement with theanchor engagement portion 92, thefree end portions 86a of theresilient legs 86 come into contact with the respectiveupper end surface 95 of the holdingclip 90. When theresilient legs 86 bend, the relative movement will in turn pull thelegs 87 upwards and thereby ensure abutment between thelower point 87a with thelower end surface 97 of theanchor engagement portion 92 of the holdingclip 90. - 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 holdingclip 90 of thehinge 10. - 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 theanchor engagement portion 92 defined by radius of curvature of the side surfaces 96 and thelower end surface 97 of the anchor engagement portion, thereby reducing stress caused by moment to an absolute minimum, leaving only tension stress inlegs 87 andlower point 87a. - 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 thelegs 87 as close to the centre of thesnap anchor 80 as possible. In this manner, the respective line of action of a pulling force acting substantially centrally in thesnap anchor 80 on one hand and the reaction force between thelegs 87 andlower point 87a with theanchor 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. - Finally, stability of the
snap anchor 80 in the holdingclip 90 and in turn of the associated coveringelement 1 b is provided by the arrangement of suitable abutment surfaces between back sides of thelegs 87 andfront sides 90a of the holdingclip 90 and between the protrudingside wall portions 81b of theguide portion 81 and theback sides 90b of the holdingclip 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 thesnap anchor 80. A sufficient stability is obtained if only opposing abutment surfaces are present though. - 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 agrip portion 84 formed at the ends of thelegs 87 opposite thetop surface 85. - The connection between the
snap anchor 80 and thecovering element - For instance, the connection is performed by fastening the
snap anchor 80 to thecovering element Fig. 14 by introducing afastening element 55 such as a screw or rivet into theopening 85a in thetop surface 85 of thesnap anchor 80. Such a rivet would be for instance a blind or pop rivet on thecovering element opening 85a. - In case the
snap anchor 80 is connected to thecovering element snap anchor 80 is so to say integral with the covering element as represented in for instanceFigs 16 and 17 . Further,Figs 16 and 17 also illustrate the snap connection as mounted.Fig. 17 is a break-out view of thesnap connection 70 as seen through coveringelement 1 b. - 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.
