- Hinge fittings used for windows of the above-mentioned type are known from WO 90/04078 and WO 99/28581.
- Such hinge fittings are used for pivotal windows, e.g. roof windows, to provide a pivoting movement, i.e. the sash turning about a hinge axis at a distance from the top and bottom member of the sash and of the frame.
- the hinge fittings comprise two extreme positions, between which one or more intermediate positions are defined. The extreme positions include a position in which the pivotal window is closed and a position in which the window sash and thus the second hinge part is turned outside at a maximum in relation to the closing position.
- Windows with the above-mentioned hinge fittings are appreciated due to their flexible properties during use, maintenance and installation. Screening arrangements mounted on a sash of such a window are often driven by an electrical power source provided in at least one of bracket members mounted on opposing sash side members. In order to provide an electrical power source to the bracket members, an electrical connection must be provided between the sash and the frame.
- the electrical connection should not affect the appreciated flexi- ble use of the window where the window is operated manually or by means of an electrically driven chain mechanism in a manner known per se and it must for example be able to sustain a full degree of rotation of the sash for cleaning purposes. Furthermore, a flexible assembly and disassembly when the sash must be separated from the frame is desirable in order to reduce production and installation costs.
- a wire is lead from a top pieces of the frame into a protective chain element to be guided between the sash and the frame of the window.
- the protective chain element provides for movement in a single plane only and thus is prevents the wire from being pinched between the sash and the frame when the window is closed.

- the pivot axis defined by the slide member and the guide member is less 90 degrees from a closed position corresponding to 0 degrees.
- a hinge pin connects the two hinge parts.
- the slide member is pivotally mounted to the base plate of the second hinge part by the hinge pin, which defines a second pivot axis. This provides for tilting the sash approximately 180 degrees in order to achieve a cleaning condition wherein the glazing normally facing outside when the window is in a closed condition, may be easily accessed.
- the second hinge part com- prises a guide pin being positioned in such a manner that during the displacement of the slide member in the guide member of the first hinge part, the guide pin is displaced along a side wall of the guide member and is thus excluding any pivoting around the second pivot axis until the guide pin is abreast of an opening in a side wall of the guide member.
- the guide pin ensures that only one pivot may work at a time, which is desirable in order to obtain a proper and stable operation of the window.
- the second hinge part further com- prises a support pin being positioned in such a manner that any pivoting around the second pivot axis is excluded while the window is in a closed position.

Description
A pivot window with electrical hinge connection
The present invention relates to a pivot window with a pair of hinges for connecting a sash and a frame, the sash and frame each comprising two side members, a top member and a bottom member defining an aperture, said sash and frame side members are connected by said hinges, respectively, and the sash may be turned in relation to the frame about a pivot axis, which is parallel to the top and bottom members, each of said hinges comprising a first hinge part comprising a base plate having a part circular guide member in the form of a guide channel comprising a concave side and a convex side, a second hinge part comprising a base plate having a part circular slide member adapted for being displaceable in the guide member, wherein the slide member interacts with the guide means and defines the pivot axis for tilting the sash with respect to the frame.
Hinge fittings used for windows of the above-mentioned type are known from WO 90/04078 and WO 99/28581. Such hinge fittings are used for pivotal windows, e.g. roof windows, to provide a pivoting movement, i.e. the sash turning about a hinge axis at a distance from the top and bottom member of the sash and of the frame. The hinge fittings comprise two extreme positions, between which one or more intermediate positions are defined. The extreme positions include a position in which the pivotal window is closed and a position in which the window sash and thus the second hinge part is turned outside at a maximum in relation to the closing position.
Windows with the above-mentioned hinge fittings are appreciated due to their flexible properties during use, maintenance and installation. Screening arrangements mounted on a sash of such a window are often driven by an electrical power source provided in at least one of bracket members mounted on opposing sash side members. In order to provide an electrical power source to the bracket members, an electrical connection must be provided between the sash and the frame.
The electrical connection should not affect the appreciated flexi-
ble use of the window where the window is operated manually or by means of an electrically driven chain mechanism in a manner known per se and it must for example be able to sustain a full degree of rotation of the sash for cleaning purposes. Furthermore, a flexible assembly and disassembly when the sash must be separated from the frame is desirable in order to reduce production and installation costs.
From WO 07/110072 is known a window with a electrical connection between the sash and the frame for providing electrical power to a screening device mounted on bracket members positioned on opposing side members of the sash. At the pivot a wire is lead from a top pieces of the frame into a protective chain element to be guided between the sash and the frame of the window. The protective chain element provides for movement in a single plane only and thus is prevents the wire from being pinched between the sash and the frame when the window is closed. In order to provide for disassembly of the sash frame the frame a plug- and-socket connection is provided in the protective chain.
G 91 06 596.8 discloses a top hung windows with an electrical connection between the sash and the frame. Visible electrical contacts are provided on the surfaces of the sash and frame members facing the surrounded aperture, respectively. When the window is closed the electrical contacts engage and provides electrical power to a screening arrangement.
A similar visible electrical connection for windows is disclosed in WO 07/053045 where electrical contact parts are provided on the top member of the frame and on the upper part of the sash side member.
The object of the present invention is to provide a pivot window with an electrical connection between the sash and the frame, which provides for facilitating the assembly of the sash and the frame.
This object is achieved by a pivot window of the kind mentioned in the introduction, which is furthermore characterized in that an inner surface of a frame side member facing the aperture and connected by one of said hinges to an outer surface of a sash side member facing away from the aperture, comprises a first electrical socket part, and
that the outer surface of the sash side member facing the inner surface of the frame comprises a second electrical socket part, that said first and second socket parts are adapted to engage for at least a part of the displacement of the slide member in the guide member in order to provide an electrical contact between the sash and frame.
It is desirable to provide the electrical sockets parts between the sash and frame members in order to protect them during use and to provide a secure use and a pleasant appearance, because the electrical sockets parts may be substantially hidden during normal use. Furthermore, the electrical connection is automatically provided during assembly of the sash and the frame and no wires are guided between the sash and the frame, which reduces the risk of squeezing the wire during installation and operation. In a further development of the invention one of said socket parts is provided in a part circular track having a curvature corresponding to the part circular guide member and in that the socket part is slidably movable in the part circular track.
Thereby it is possible to achieve an electrical connection for a larger part the movement of the sash with respect to the frame. This is desirable because when a window is in a ventilation condition, it is often necessary to control an electrically driven screening device mounted in the sash.
In a mechanically simple preferred embodiment said part circu- lar track comprises a wire adapted to follow the movements of the slidably movable socket part.
In a preferred embodiment at least one of said first electrical socket part is positioned on the hinge part mounted on the frame or that said second electrical socket part is positioned on the hinge part mounted on the sash.
By mounting the electrical socket parts on the hinge parts, the socket parts may be better protected during installation of the window and the manufacture and assembly of the window is furthermore facilitated because fewer parts must be connected.
In a preferred embodiment of the invention, which provides for a secure use of the window, said first socket part is a female socket part, which minimizes the risk touching any electrical contact points provided with electrical power during operation of the window. In a preferred mechanically simple embodiment a wire is guided from the socket part mounted on the sash to a bracket member mounted on a surface of the sash side member facing the surrounded aperture.
In a further development, which provides for a even more facili- tated manufacturing and improved operation of the window, one of said base plates is provided with a through-going part circular recess having a curvature corresponding to said part circular track.
This makes the sliding movement of the second socket very stable and facilitates the replacement of spare part if necessary, as the sockets parts may be made more accessible when mounted on a hinge than on a frame of for instance wooden material.
In an especially appreciated embodiment with a desirable operation of the window, said displacement of the slide member in the guide member defines a tilting axis being outside the window thickness. In an other preferred embodiment, which has shown to be especially useful during normal operation, the pivot axis defined by the slide member and the guide member is less 90 degrees from a closed position corresponding to 0 degrees.
In a mechanically simple preferred embodiment, which provides for a more smooth and stable operation of the window, a hinge pin connects the two hinge parts.
In a very useful embodiment of the invention, the slide member is pivotally mounted to the base plate of the second hinge part by the hinge pin, which defines a second pivot axis. This provides for tilting the sash approximately 180 degrees in order to achieve a cleaning condition wherein the glazing normally facing outside when the window is in a closed condition, may be easily accessed.
In another preferred enhancement, the second hinge part com-
prises a guide pin being positioned in such a manner that during the displacement of the slide member in the guide member of the first hinge part, the guide pin is displaced along a side wall of the guide member and is thus excluding any pivoting around the second pivot axis until the guide pin is abreast of an opening in a side wall of the guide member.
The guide pin ensures that only one pivot may work at a time, which is desirable in order to obtain a proper and stable operation of the window.
In a further improvement, the second hinge part further com- prises a support pin being positioned in such a manner that any pivoting around the second pivot axis is excluded while the window is in a closed position.
This ensures proper operation of the sash with respect to the frame and makes sure that the two hinge parts engage and interact cor- rectly. Thereby a precise engagement and contact between the electrical socket parts may be achieved when the window is operated from one extreme position to another.

In Fig. 1 a pivot window 1 is shown in an open state, i.e. a win-
dow having a hinge axis that is positioned at a distance from opposite top members 13, 23 and bottom members 14, 24 of a sash 4 and a frame 5, and is substantially parallel to the opposite top members 13, 23 and bottom members 14, 24. For instance, the hinge axis may be sub- stantially central with respect to opposite pieces of the sash 4 and frame 5. In the window 1, the sash 4 and frame 5 each comprises two side members 11, 12 and 21, 22, respectively, a top member 13 and 23 and a bottom member 14 and 24. The sash 4 and frame 5 each surrounds a substantially rectangular opening 15 and 25, the opening 15 being cov- ered by a glazing. The frame constituted by the frame members 21-24 is formed as a main frame adapted to be built-into a building structure, for instance the roof structure of an inclined roof. The sash 4 may be turned in relation to the frame 5 about the hinge axis, which is parallel to the top and bottom members. In the above, the hinge has been described as used with a centre hung pivot window. It is, however, to be understood that it may also be used with a window having its hinge axis elsewhere between the centre and the top, and with other structures functioning in a similar manner, without thereby departing from the scope of the claims. The sash side members 11, 12 are connected to the frame side members 21, 22, respectively, by means of mirror- in verted hinge fittings 50 to be described in more detail below. Fig. 2 shows the sash side member 11 connected to the frame side member 21 by a hinge fitting 50 of a window in a closed condition and Fig. 3 shows the same detail as Fig. 2 where the sash has been moved approximately 47 degrees to a ventilation position.
The hinge fitting 50 as shown in Figs. 4-9 for a pivotal window 1 comprises a first hinge part 60 having a base plate 61 adapted to be secured to a side member 21 of the frame 5 of the window as shown in Fig. 5, where a second hinge part 80 engages with the first hinge part 60. The second hinge part 80 is also provided with a base plate 81 adapted to be secured to a sash side member 11 as shown in Fig. 4, where the first hinge part 60 interacts with the second hinge part 80. It should be noted that a corresponding but reverse hinge fitting is
mounted on the opposite pair of frame and sash side members to determine a pivot axis essentially parallel to the top member 13, 23 and bottom members 14, 24 of the sash 4 and the frame 5. Each base plate
61, 81 of the hinge parts 60, 80 comprises pins 71, 87 for securing in bores of the frame and sash, respectively, and bores 93 for further fastening with for instance screws.
On the base plate 61 of the first hinge part 60, a plate piece 62 is secured by means of rivets or screws 63 and at a distance from the base plate 61 and provided with a part circular guide channel constitut- ing a control means 64 for receiving a slide member 82 generally in the form of a slide bar of the second hinge part 80. The guide channel 64 comprises a convex side wall 65, a concave side wall 66, bottom end 67, a introduction end 68 and a open section 69. The slide member 82 of the second hinge part is by means of a hinge pin 83 pivotally connected with the base plate 81 of the second hinge part 80, which also has a guide pin 84, the function of which will be explained in the following. Evidently, the slime member 82 may in an alternative embodiment of the invention, which only provides for a hinge with a ventilation condition, be an integral part of the second hinge part 80 and not connected to the base plate 81 by a hinge pin.
The convex side wall 65 of the guide channel 64 comprises beside the plate piece 62 one or more lamellae 70 placed between the plate piece 62 and the base plate 61, and which together with the plate piece 62 forms an abutment face for the slide member 82 and the guide pin 84. In the convex side 66 of the guide channel 64 between the plate piece 62 and the base plate 61 a pin or a screw may be provided in order to strengthen and secure the base plate 62 of the guide channel 64. The use of lamellas for parts of the guide way plate piece 62 limits the overall weight of the hinge and the material consumption. The guide pin 84 fixed on the base plate 81 of the second hinge part 80 prevents any turning of the base plate on the pivot of the hinge pin 83 until a stop pin 85 has been brought into abutment with a recess 71 of the plate piece
62. In this situation the guide pin 84 is abreast the open section 69 of the plate piece 62 so that the hinge pin 83 allows the further turning of
the sash 4 in the opening direction in order to achieve a cleaning condition of the window. Parts of the hinges such as the guide pin 84 and the side wall of the guide channel 64 may be provided with a noise reducing material such as a plastic coating. Further, the guide channel 64 may be provided with a lever spring (not shown) to provide a braking action in a manner known per se during movement of the sash 4 with respect to the frame 5.
The first hinge part 60 comprises a first socket part 72. When the hinge part 60 is mounted on a frame side member 21 an electrical wire is guided from a bore or a recess in the frame surface facing the surrounded aperture 25 to the first socket part 72 in order to provide an electrical contact point in connection with the first hinge part 60. The first socket part 60 is preferably a female socket with a part circular bore 73 with at least one electrical contact point for receiving a corresponding socket part 88 in connection with the second hinge part 80. As to be described in the following, the electrical sockets 72, 88 are preferably mounted on the hinge parts 60, 80. In general the electrical socket parts 72, 88 are preferably positioned close to the hinge axis in order to provide the electrical connection between the sash 4 and the frame 5 for a larger portion of the movement of the sash 4 corresponding to operation with an electrical driven chain mechanism. The first socket part on the frame is preferably a female socket part because this socket part is continuously provided with electrical power after installation. Hence, the risk of a user getting in contact with the electrically powered parts during op- eration of the window 1 is minimized.
The corresponding second socket part 88 is a male socket part mounted in a elongate part circular recess 90 having a curvature corresponding to the curvature of the guide channel 64 of the first hinge part 60. The male socket part 88 comprises a body part with a protrusion 93 for mounting in the part circular recess 90. In a preferred embodiment the recess 90 is provided with a gasket 91 having a recess corresponding to the recess 90 of the base plate 81 and mounted to the base plate 81 with screws or pins 92. A part circular portion of the protrusion 93 is adapted to be guided in the recess constituted by the recess 90 and the
gasket 91. The gasket simply increases the dept of the recess and thereby provides a more stable guidance of the protrusion during operation of the window. Evidently, this may be made as an integral part of the hinge plate 81 or by means of a thicker hinge plate in order to re- ceive the same result. In a preferred embodiment as shown in Fig. 7 the second socket part 88 is slidable in the recess 90 in a manner to be described in more detail below. In case of using a gasket 91 it may be made of an electrical insulating material, which may ensure that in case of a malfunction of a socket part there is no electrical connection be- tween the second socket part 88 and the second hinge part 80. For engaging with the part circular bore 73 of the first socket part 60 the second socket part 88 is provided with a corresponding part circular pin 89 having at least one electrical contact point. When the second hinge part 80 is mounted on a sash side member 11 a flexible electrical wire is guided from a hole or recess in the outer sash surface facing the inner surface of the frame 5 to the second socket part. In the sash behind the recess 90 a milled groove housing the flexible electrical wire in provided. The wire is adapted to follow the movements of the slideable socket part. In the preferred embodiment when the electrical socket parts 72, 88 are mounted on the hinge parts and the wire is guided through the recess 90 to a centre hole of the part circular protrusion and further to the part circular pin 89. The hole in the sash surface is preferably shaped like the recess 90 of the base plate 81.
The wire connected to the hinge part 80 mounted on the sash 4 is guided to a bracket member positioned on the inner surface of the sash side member facing the surrounded aperture. The bracket member provided with electrical contact point and adapted to receive an electrical driven screening device, which thereby may be provided with electrical power as long as there is electrical contact between the socket parts 72, 88 of the hinge 50.
The circular pin 89 of the male socket part 88 and the corresponding circular bore 73 typically comprises a positive electrical contact point and a negative electrical contact point connected to the corresponding negative and positive wire parts of the wire guided to the
socket parts 88, 89, respectively. Evidently, the contact points of the two socket parts may take many forms such as a pair of rings surrounding a portion of part circular pin 89 and a corresponding part of rings positioned on a wall of the part circular bore 73. The corresponding contact points of the two contact parts 88, 89 may be made as dents and projections in order to achieve tolerance and friction when the two contact parts engage. By providing more than one pair of electrical contacts even further tolerance may be achieved.
When the slide member 82 is guided into the guide channel 64 of the first hinge part 60 and the two hinges engage, the male socket part 88 will engage with the female socket part 72 and the second socket part 88 will be positioned in the recess 90 as shown in Fig. 7 when the window is in a closed condition. Due to friction between the two socket parts 72, 88, the second socket part 88 will be guided in the recess 90 towards the opposite end as shown in Fig. 9, when the slide member 82 is moved outward the guide channel 64 to achieve a ventilation position of the window 1. The use of a sliding contact part ensures that the sash 4 is provided with electrical power even when positioned in a ventilation position. When the second socket part 88 reaches the op- posite end of the recess 90 and the second hinge part 80 is moved any further, the second socket part 88 is released from the first socket part 72 and the electrical connection between the two hinge parts is interrupted.
Since the electrical power is provided from the first hinge part 60 mounted on the frame to the second hinge part 80 mounted on the sash, the second hinge part is preferably provided with a male socket part, which minimizes the risk touching any electrical contact points provided with electrical power during operation of the window. However, the electrical socket parts can be made in many conceivable ways and may be provided on other parts of the hinge parts 60, 80. In another mechanically simple embodiment the electrical contact between the socket parts 72 and 88 when the slide member 82 is moved, may be achieved with an extended part circular pin 89, which engages with the part circular recess 73 of the first socket part for a larger part of the movement
around the pivot defined by the guide channel 64. Preferably, only one side of the window is provided with electrical socket parts according to the invention, since this will keep the need for wiring at minimum.
Evidently, either or both of the socket parts may be mounted di- rectly on the sash 4 and frame 5 instead of being an integral part of the hinge parts. However, the socket parts 72 and 88 are better protected during installation and by having the parts integrated and the manufacture and the assembly of the window is facilitated. Furthermore, it is an advantage to position the socket parts close to or on the hinge so that the socket parts are not visible during normal operation.
In a preferred embodiment of the invention as shown in Fig. 8, the window sash 4 and thus the second hinge part 80 are turned out to an opening angle of about 47 degrees from the closing position, i.e. to a ventilation position of the window 1. In Fig. 9 the slide member 82 is almost displaced at a maximum out of the guide channel 64, i.e. until the stop pin 85 on the slide member 82 has been caught in the recess 71 of the plate piece 62, which corresponds to an opening angle of about 80 degrees. In general the part circular guide channel 64 and the slide member 82 interact and define an axis of rotation, which is less than 90 degrees between the closed condition and a condition of maximum ventilation. However, the base plate 81 may be turned further about the hinge pin 83 in order to obtain a view to cleaning the outside of the window. When closing the window again, the base plate 4 is turned back until the guide pin 10 enters the open section 69 of the guide channel 64. At the same time, a support pin 86 brings the slide member 82 in a position on the base plate 81, which position is fixed during the remaining part of the re-closing of the window 1.
When closing the window 1 from the position shown in Fig. 9, the second socket part 88 eventually engages with the first socket part 72 of the first hinge part 60 and the electrical connection between the two hinge parts 60, 80 is re-established. This is furthermore an advantage when installing the window, since the electrical connection between the sash 4 and the frame 5 is automatically established when the hinge
parts of the sash 4 is mounted in the hinge parts of the frame 5 in a manner known per se.
The invention is not limited to the embodiment shown and the embodiments described above, but several modifications are conceiv- able.
