Definitions

• 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 flexible 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 desir- able 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.
• 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 elec- trical contacts engage and provides electrical power to a screening arrangement.
• US 2003/0043020 discloses a signal transfer assembly for supplying a signal from a door frame to a door and includes a strip assembly in the upper door frame member for receiving a signal and for passing the signal to a transfer tip assembly in the door in order to lock the door when the door abuts the door frame.
• 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.
• 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.
• one of said socket parts is guided in a part circular track following the curvature of the part circular guide member.
• 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. Further- more, 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.
• 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.
• said part circular track comprises a wire adapted to follow the movements of the slidably movable socket part.
• 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.
• 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.
• 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.
• one of said base plates is provided with a through-going part circular recess having a curvature corresponding to said part circular track.
• said displacement of the slide member in the guide member defines a tilting axis being outside the window thickness.
• 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 con- nects 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 comprises 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.
• the circular track guiding a socket part is provided in the part circular guide member of the first hinge part and that the socket part is an integral part of a guide pin of the second hinge part.
• the circular track guiding a socket part is provided in a sidewall forming the part circular guide member.
