Description

[0028] The present invention shall be explained in detail below with reference to the embodiments shown in the figures. Using the figures, the present invention is explained in detail with reference to a window according to the invention. However, it is self-evident that the statements in this respect can also be applied correspondingly to a door according to the invention. In the figures

[0029] FIG. 1 shows a schematic cross-sectional diagram of a window according to an embodiment of the present invention;

[0030] FIG. 2 shows a schematic diagram of a functional element in the form of a composite pane element which is used in the embodiment of the window according to the invention shown in FIG. 1; and

[0031] FIG. 3 shows a schematic view of a building wall with the window according to the embodiment of the present invention shown in FIG. 1.

[0032] FIG. 1 shows a detail of a cross-sectional diagram of an embodiment of a sash unit 1 of the window 2 according to the invention using the example of a plastic sash unit with a sash 3 in the form of a plastic hollow profiled frame. The sash 3 of the window 2 according to the invention is constructed of portions of a hollow-chamber profiled element 4. In the embodiment of the window 2 according to the invention shown in FIG. 1, the hollow-chamber profiled element 4 is produced from a thermoplastic polymer material, preferably polyvinyl chloride (PVC), in particular hard PVC (PVC-U) or glass-fiber-reinforced PVC, to which additional additives such as stabilizers, plasticizers, pigments and the like are added. The hollow-chamber profiled element 4 is constructed from a plurality of hollow chambers, which are each surrounded by webs of the sash 3. Centrally, the sash 3 comprises a main hollow chamber 5, in which a reinforcement element 6, in particular a steel reinforcement element, is accommodated. An upper web of the main hollow chamber 6 forms a glazing rebate 8 together with an outer lip 7. On the side opposite the outer lip 7, the sash 3 has a bead groove 9 in which a glazing bead 10 is anchored. In the embodiment shown in FIG. 1, the glazing bead 10 is situated on the side facing the room. The glazing bead 10 is used to stabilize a planar element 11 which is accommodated in the glazing rebate 8 and is in the form of insulating glazing, in particular insulating triple-glazing, in the embodiment shown in FIG. 1. The upper web of the main hollow chamber 5 is thus opposite the planar element 11 accommodated in the glazing rebate 8. By means of a glazing bridge (not shown) and a glazing packer (not shown) laid on its supporting surface, the planar element 11 is held in position in the sash 3.

[0033] In the main hollow chamber 5 of the sash 3 there is a constituent part 12 of a multi-part control element 12, 12′. The constituent part 12 of the multi-part control element 12, 12′ is fed through a cut-out in the upper web and in the profiled element wall of the hollow-chamber profiled element 4 of the sash 3 opposite the upper web. In the embodiment shown in FIG. 1, the alarm element 6 is U-shaped. The constituent part 12 of the control system 12, 12′ is then accommodated in the U-shape of the reinforcement element. On the side facing the planar element 11, the reinforcement element 11 has bores for the interfaces or connections of the further constituent part. In alternative embodiments, the constituent part 12 can also be arranged in such regions of the sash 3 in which there is no reinforcement element 6 in the main hollow chamber 5. It is likewise conceivable for the window according to the invention to have two or the door according to the invention to have no alarm elements. This has the advantage that the constituent part 12 accommodated in a hollow chamber 5 of the hollow-chamber profiled element 4 only has to be fed through cut-outs in the hollow-chamber profiled element 4, and therefore no complex bores in the alarm element 6 are necessary. In such cases, the hollow-chamber profiled element 4 is preferably in the form of a fiber-reinforced, in particular glass-fiber-reinforced hollow-chamber profiled element.

[0034] The constituent part 12 of multi-part control element 12, 12′ is connected conductively to a functional element 13, which is in the form of a composite glass pane and, in the embodiment of the window 2 according to the invention shown in FIG. 1, forms the pane of the planar element 11, in the form of insulating triple-glazing, facing the glazing bead 10.

[0035] In the embodiment of the present invention shown in FIG. 1, the constituent part 12 of the control element 12, 12′ has electrical interfaces. This allows a simple power supply to the constituent part 12 of the control element 12, 12′ and a simple possibility of communicating between the constituent part 12 of the control element 12, 12′ and the further constituent part 12′ thereof. The electrical interfaces are preferably arranged on two mutually opposing sides of a housing of said constituent part 12. The connection of the constituent part 12 can thus be made from the side facing away from the planar element 11. Furthermore, a connection from the constituent part 12 of the control element 12, 12′ to the functional element 13 can be established easily.

[0036] In the embodiment of the present invention shown in FIG. 1, the functional element 13 is in the form of a PDLC functional element. An exemplary functional element 13 which can be used in a window 2 according to the invention or in a door according to the invention is shown in a schematic diagram in FIG. 2.

[0037] In this embodiment, the functional element 13 comprises four functional zones 14, 14′, 14″, 14″′ and a conductor carrier 15; in another embodiment, the functional element 13 can also comprise a different number of functional zones 14, 14′, 14″, 14″′. Each of the functional zones 14, 14′, 14″, 14″′ comprises at least one contact point 16, 16′, 16″, 16″′, at which the respective functional zone 14, 14′, 14″, 14″′ is electrically conductively contacted to the conductor carrier 15. The functional element 13 can be for example in the form of an SPD functional element, PDLC functional element, EC functional element or a combination of the aforementioned functional elements.

[0038] The conductor carrier 15 is arranged in an edge region of the functional element 13 and, in the embodiment shown, has four conducting elements of the conductor carrier 15, to each of which a functional zone 14, 14′, 14″, 14″′ of the functional element 13 is assigned.

[0039] The conducting elements of the conductor carrier 15 lead into a connection 17, which in turn has a socket into which a connector of a cable 18 is received, in particular plugged. Via the cable 18, the functional element 13 can be connected to the constituent part 12 of the multi-part control element 12, 12′. The constituent part 12 of the multi-part control element 12, 12′ is at least partially accommodated in the main hollow chamber 5 of the sash 3. A conductor 19, which is connected to the functional zones 14, 14′, 14″, 14″′ of the functional element 13, can likewise be connected to the constituent part 12 of the multi-part control element 12, 12′.

[0040] The multi-part control element 12, 12′ can be for example in the form of a controller. In addition to the constituent part 12, the multi-part control element 12, 12′ also comprises a further constituent part 12′. The further constituent part 12′ is connected to external power supply and additionally connected via cables or induction to the constituent part 12. As a result, a variable voltage, via which the light transmission properties of the planar element 11 can be varied, can be applied to the functional element 4 via the multi-part control element 12, 12′.

[0041] FIG. 3 schematically shows an embodiment of a building wall 100 according to the invention which has an aperture in which the window 2 according to the invention shown in FIG. 1 is accommodated. The planar element 11 is accommodated in the sash 3. When the window 2 according to the invention is in the closed state, the window sash unit 101 thus formed bears against a frame (not shown) via seals and is mounted rotatably on the frame via fittings (not shown).

[0042] The further constituent part 12′ of the multi-part control element 12, 12′ is accommodated in the building wall 100 within the surroundings of the window 2. The further constituent part 12 of the control element 12, 12′ is configured to provide the power supply to the constituent part 12 of the control element 12, 12′ partially accommodated in the main hollow chamber 5 of the sash. The constituent part 12 of the control element 12, 12′ which is partially accommodated in the main hollow chamber 5 of the sash 3 and the further constituent part 12′ of the control element are connected to one another for communication. This ensures exchange of information between the constituent parts 12, 12′. A BUS connection, in particular CAN, has proven suitable for this purpose.

[0043] In the embodiment shown in FIG. 3, the further constituent part 12′ is in the form of a flush-mounted element. Only the operating surface 20 of the further constituent part 12′ facing the room, which operating surface acts as the input element 20 for the control element 12, 12′, protrudes out of the building wall 100 according to the invention. The operating surface 20 is touch-sensitive. Such a touch-sensitive design of the input element 20 allows intuitive operation of the window 2 according to the invention.

[0044] The present invention has been described by way of example with reference to the embodiment of the present invention shown in the figures. It is self-evident that the present invention is not limited to the embodiment shown in the figures, but rather the scope of the present invention results from the attached claims.
