Description
- The present invention relates to a hinge arrangement for a roof window having a frame with a plurality of frame members and a sash with a plurality of sash members and carrying a pane, said hinge arrangement comprising: a set of hinges, each including a frame hinge part configured to be connected to one frame side member in a mounted condition, and a sash hinge part configured to be connected to one sash side member opposite said frame member in the mounted condition, said sash hinge part being adapted to be rotated relative to the frame hinge part about a hinge axis extending substantially perpendicularly to the longitudinal direction of the frame side member and the sash side member in the mounted condition, within a predefined angle interval, guiding means providing guidance for the sash hinge part relative to the frame hinge part, and motion modulating means configured to act on the hinge to affect the movement of the sash hinge part relative to the frame hinge part over at least a part of the predefined angle interval. The invention furthermore relates to a roof window including a set of hinges.
- 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.
- In such roof windows, the most common hinge arrangement makes use of a so-called pivot hinge which has attained more or less industry standard status. The pivot hinge comprises an arc-shaped guidance in the frame hinge part to receive a sliding element. In order to be able to position the sash in an arbitrary open position, motion modulating means are provided to obtain a braking action on the sash hinge part relative to the frame hinge part, typically in the form of a leaf spring protruding into the arc-shaped guidance and interacting with the sliding element.
- Although this pivot hinge has proven to function extremely well, it is not desirable in all fields of application. This is mainly due to the fact that the braking action provided by the friction of the leaf spring is difficult to control and may under some circumstances also need maintenance such as lubrication.
- The document
US2187464 discloses a hinge according to the preamble ofclaim 1. - With this background it is an object of the present invention to improve a hinge arrangement with respect to the overall operability conditions.
- In a first aspect, this and further objects are met by a hinge arrangement according to
claim 1. - In this manner, a simple hinge arrangement is provided, but which at the same time provides for the improved operability aimed at, since the motion modulating means cooperate with the guiding means to provide a kinetic pattern in the hinge arrangement when in use, i.e., during opening, closing and parking the window sash in arbitrary positions. The invention is furthermore based on the recognition that even though the simplified hinge connection provides a well-defined point of rotation in the hinge pin itself, it has proven surprisingly advantageous to be able to affect the movement of via the guiding means.
- In a presently preferred embodiment, the motion modulating means comprise a biasing device. Thus, the movement of the sash hinge part is supported by the biasing device which provides a torque about the hinge pin of the hinge arrangement. In a further development of this preferred embodiment, the biasing device includes a spring. This is a mechanically simple manner of providing the bias.
- According to the invention, the motion modulating means comprise a braking device.
- According to the invention, the guiding means comprise a transmission device. This makes it possible to combine the two functions of guiding the movement of the sash hinge part relative to the frame hinge part, and transmitting the force provided by the motion modulating means. In a development of this embodiment, the transmission device comprises a rack slidably connected to the frame hinge part, to cooperate with a pinion connected to, preferably integral with, the sash hinge part. The rack-and-pinion coupling is a simple and reliable mechanical structure.
- In a second aspect, a roof window comprising a hinge arrangement is provided.

Fig. 37 is a cross-sectional view along the line XXXVII-XXXVII ofFig. 36 . - In the following, embodiments of the inventive roof window will be described in further detail. For reference, a prior art roof window with a frame 1', a sash 2', a pane 3' and a hinge 10' is shown in
Fig. 1 . Parts of the prior art roof window which are applicable also to a roof window according to the invention are described in Applicant's published Europeanpatent applications EP 2 770 146 A1 andEP 2 770 149 A1 - Thus, in a manner known per se, the roof 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 11' and one sash side member 21' 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 21' is substantially parallel with the frame side member 11', to an open position, in which the sash side member 21' forms an angle with the frame side member 11'. During this movement the sash 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 or offset slightly above or under the centre depending of the actual need for an optimal balancing of the weight of the sash, including various structural modifications thereof affecting the overall weight and different types of pane configuration with one, two or multiple layers of glass. - 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 at the sash top member with a lock mechanism to interact with a striking plate on the frame top member. This operating and locking assembly could include a ventilation and control flap as described in applicant's
patent EP 2 607 578 B1 . The set of hinges 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 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 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'. - 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 exterior surfaces 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 direction longitudinal is, if nothing else is mentioned, longitudinal along the length of the frame.

hinge 5 includes aframe hinge part 51 configured to be connected to oneframe side member 11 in a mounted condition. The term configured implies that suitable forms of mounting means such as holes and screws are provided although not shown. Correspondingly, asash hinge part 52 is configured to be connected to onesash side member 21 opposite saidframe member 11 in the mounted condition. - The sash hinge
part 52 is adapted to be rotated relative to theframe hinge part 51 about a hinge axis α, cf.Fig. 7 , extending substantially perpendicularly to the longitudinal direction of theframe side member 11 and thesash side member 21 in the mounted condition, within a predefined angle interval. Typically, the predefined angle interval in normal use in a standard roof inclination is 0 to 90 degrees, but the sash may also be able to rotate such that the external side of thepane 3 is accessible from the interior, i.e., about 180 degrees. - As will be described in further detail below, guiding means providing guidance for the
sash hinge part 52 relative to theframe hinge part 51 are provided in conjunction with motion modulating means configured to act on thehinge 5 to affect the movement of thesash hinge part 52 relative to theframe hinge part 51 over at least a part of the predefined angle interval. - The frame hinge
part 51 and thesash hinge part 52 of thehinge 5 are connected to each other by ahinge pin 53 such that the hinge axis α extends through theframe hinge part 51 and thesash hinge part 52. This entails that the hinge axis α is located within the circumference of both hingeparts - Furthermore, the guiding means are provided at a distance from the
hinge pin 53 and in connection with the motion modulating means. - In this first embodiment, the motion modulating means comprise a
biasing device 7. The term biasing encompasses the ability of one part to affect another part with a pre-load or force. The biasing may be tensional or compressional, but other kinetic configurations are conceivable. - In the first embodiment shown, the
biasing device 7 includes aspring 71 in the form of a coil spring which is at one end fastened to anabutment 72 and at the other end to a connectingelement 73 providing the connection to the guiding means of thehinge arrangement 4. - Here, the
abutment 72 is stationary in thehinge arrangement 4 and the connectingelement 73 is movable. It is also conceivable to make also the abutment movable with suitable check means. - The guiding means comprise a

Thehinge pin 53 is here shown connected to thebase plate 51a of theframe hinge part 51 and journaled in thesash hinge part 52. Furthermore, thesash hinge part 52 to comprise abridge portion 52b connected to thebase plate 52a and anarc portion 52c connected to thebridge portion 52b. In the case thepinion 62 is integral with thesash hinge part 52, thepinion 62 may as shown be formed at the periphery of thearc portion 52c. - To provide the connection between the guiding means and the motion modulating means, the
rack 61 is connected to thebiasing device 7. In use, for instance by opening the sash relative to the frame, thespring 71 of thebiasing device 7 exerts a force on therack 61 which moves accordingly and induces a rotating movement on thesash hinge part 51 via thepinion 62. - Referring in particular to
Fig. 7 , the hinge axis α of thehinge arrangement 4 is located to the exterior of the upper pane line t. The position of thehinge arrangement 4 in the roof window is chosen such that the distance between the hinge axis α and the upper pane line t lies in the interval 0 to 50 mm, preferably 5 to 30 mm, most preferably 10 to 20 mm. - In the first embodiment, it is seen that the
hinge arrangement 4 is located entirely on the exterior side of the upper pane line t. Thus, theframe hinge part 51 is fastened to a top surface of theframe side member 11 and thesash hinge part 52 to a top surface of thesash side member 21. - A
gap 9 is provided between theframe side member 11 and thesash side member 21. A number ofsealings 91 is provided in recesses in theframe side member 11. - In the second embodiment shown in
Figs 8 to 13 , elements having the same or analogous function are denoted by the same reference numerals as in the first embodiment, to which 100 has been added. Correspondingly, in the third embodiment elements carry the same reference numerals to which 200 has been added, and so on. The components of the roof window are denoted by the same reference numerals throughout. Only differences relative to the first embodiment will be described in detail. - The
hinge arrangement 104 comprises as in the first embodiment abiasing device 107 and atransmission device 106 of substantially identical configuration. - The main difference from the first embodiment resides in that the
hinge arrangement 4 is located at least partly on the interior side of the upper pane line t. To this end, theframe side member 11 comprises a set of recesses to accommodate parts of thehinge arrangement 104. Of these recesses,longitudinal recess 111 to receive thebiasing device 107 is indicated inFig. 10 . Thesash side member 21 is also provided with recesses to accommodate such parts of thehinge arrangement 104. - Also indicated in connection with the second embodiment, cf.
Fig. 11 , is the distance d between thehinge pin 153 and the point of action of the motion modulating means on the guiding means of thehinge arrangement 104, viz. at the mesh between the rack and pinion of thetransmission device 106. The distance d is an indication of the torque attainable to affect the movement of thesash hinge part 52 and hence of theentire sash 2. It is noted that such a distance d is present in all of the embodiments of the present invention, although not indicated explicitly throughout. - In the third embodiment according to the invention shown in
Figs. 14 to 19 , the guiding means comprise atransmission device 206 in the first and second embodiments. - The motion modulating means comprise a
braking device 208. - The
braking device 208 comprises a plurality ofwheels 2081, here connected to theframe hinge part 251, to interact with anengagement element 2082 in connection with the guiding means 206 of thehinge arrangement 204. - The plurality of

braking device 208 comprises abar 2082 to cooperate with the plurality ofwheels 2081. Thebar 2082 is in the embodiment shown connected to therack 61 of thetransmission device 206 forming part of the guiding means of the third embodiment. - In the fourth embodiment shown in
Figs 20 to 25 , the guiding means 306 of thehinge arrangement 304 comprise an arc configuration and the engagement element of thebraking device 308 constituting a part of the motion modulating means comprises aslide element 3082 to cooperate with the plurality ofwheels 3081. - In the fifth embodiment shown in
Figs 26 to 31 , the guiding means comprise atrack set 406 to accommodate the connectingelement 473 of thebiasing device 407 constituting part of the motion modulating means of thehinge arrangement 404. - In this fifth embodiment, a
first track 461 is provided in theframe hinge part 451 and asecond track 462 in thesash hinge part 452. The connectingelement 473 of thebiasing device 407 is received in both of thesetracks - Referring in particular to
Fig. 29 , the movement of thesash hinge part 452 relative to theframe hinge part 451 assisted by the cooperation between the motion modulating means and the guiding means is indicated. Thespring 471 of thebiasing device 407 forming part of the motion modulating means exerts a force on the connectingelement 473 which in turn is transferred into a torque due to the distance d from the point of action to thehinge pin 453. - The sixth embodiment, shown in
Figs 32 to 37 , corresponds in substance to the first embodiment to whichbraking device 508 corresponding to thebraking device 208 of the third embodiment has been applied. - Thus, the guiding means of the sixth embodiment according to the invention comprise
transmission device 506 and the motion modulating means comprise both biasingdevice 507 andbraking device 508. This offers a further improved possibility to control the motion during opening and closing of the roof window, i.e. rotating thesash 2 relative to theframe 1. - In further, not shown embodiments, other combinations between the shown and described embodiments may be carried out. Moreover, the motion modulating means may comprise an external drive device, for instance electrically driven.
- 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.
