Description

[0001] The invention relates to a window system with a tilt window designed for vertical installation, in particular a tilt-and-turn window, which has a window frame and a window sash, and with a tilt actuation device.

[0002] Windows are used in various sections of buildings, particularly residential buildings. Common examples include skylights and hatches, which can be mounted at an angle or horizontally. To open a window sash against gravity, spring mechanisms, pivot points located in front of the window's edge, electric drives, or similar devices can be used.

[0003] In contrast, the present invention relates to simple windows designed for vertical installation. The window plane is vertical, except for construction tolerances of typically a few degrees. Such windows are also commonly referred to as facade windows.

[0004] With regard to such facade windows, the present invention specifically relates to tilt windows that can be tilted outwards from the vertical plane for ventilation. The window sash is supported at its lower edge by the window frame and tilted away from the window frame at its upper edge. The opening angle, i.e., the angle relative to the vertical, can typically be between 10° and 15°. With a standard window size, the opening gap at the upper edge can then be 8 cm to 15 cm. This also includes floor-to-ceiling windows as well as balcony and patio doors, which in their construction correspond to standard facade windows.

[0005] The described open position is usually held by a lever mechanism. Due to the relatively small deflection, tilting can be done with relatively little force because the weight of the window sash is mostly supported at the bottom of the sash against the window frame.

[0006] In practice, tilt-and-turn windows are particularly common, which, in addition to the tilt function described, can also be opened. The corresponding window sashes can then also be pivoted around a vertical axis relative to the window frame, with switching between a closed position, the pivot function, and the tilt function being accomplished by a window handle and an attached mechanism.

[0007] The present invention relates to the automation of the tilting function by means of a tilting actuation device.

[0008] Appropriate tilting operating devices for vertically mounted tilt windows, in particular tilt-and-turn windows, are known in various designs.

[0009] DE 38 40 101 A1 describes tilt-operating devices that include a pull cable. The design is comparatively complex, requiring the components to be permanently mounted to the window frame and sash.

[0010] DE 41 15 054 A1 discloses an actuating device, which is particularly designed for a pivoting movement. Decoupling is also possible, allowing the window sash to be operated manually in the known manner. According to DE 41 15 054 A1, a comparatively complex fixed mounting on the window frame and / or the window sash or an adjacent building surface is also necessary. Decoupling of a drive is also known in various designs from FR 3 118 086 A1.

[0011] DE 35 01 042 A1 describes a tilting operating device which operates under tension using a nylon cord as a pulling element. If the tilting window is not forced into the open position by its own weight or, for example, by spring tension, active opening is not possible.

[0012] German patents DE 89 07 144 U1 and DE 10 2013 219 040 B4 describe operating devices that are integrated into the window itself. Accordingly, factory installation is necessary, resulting in a comparatively complex overall arrangement. Retrofitting the automated tilt function is generally not possible.

[0013] US Patent 4,014,136 discloses an actuating device with a chain, which can be designed to be particularly compact. This actuating mechanism must also be appropriately mounted on or integrated into the window frame and the window sash.

[0014] The present invention is based on the objective of providing a window system that is easy to install, has good functional properties and also allows for easy dismantling of the automated tilt function.

[0015] The subject matter of the invention and the solution to the problem are a window system according to claim 1, a tilting actuation device for the window system according to claim 20, and a building arrangement according to claim 21.

[0016] The invention therefore relates specifically to a window system with a tilt window designed for vertical installation, in particular a tilt-and-turn window, which has a window frame and a window sash, and with a tilt actuation device which has a pull-push means and a drive module for the pull-push means, wherein the window sash covers the window frame with an upper window rebate at an upper edge, wherein the drive module is attached to the upper window rebate.

[0017] According to the invention, the drive module is attached to the upper window rebate, where a clamping and, in particular, reversible attachment is possible in a particularly simple manner. Due to the support on the upper window rebate, the drive module can also be suspended there, so to speak, whereby the weight of the drive module is securely supported and can even contribute to a suitable fastening.

[0018] According to a preferred embodiment of the invention, at least one retaining element of the drive module engages the upper window rebate. For example, two spaced-apart retaining elements in the form of clamps or clamping brackets can be provided, which engage the upper window rebate. The drive module is then suspended by its weight via the at least one retaining element, whereby clamping with the upper window rebate is also possible.

[0019] For example, the upper window rebate can be clamped between a clamping surface of at least one retaining element and a corresponding surface on the housing of the drive module. This described gripping of the upper window rebate, combined with the force of gravity, results in a secure, form-fitting attachment of the drive module to the upper window rebate and thus to the entire window sash. In particular, an additional clamping action allows for a force-fit attachment, further protecting the drive module against slippage and ensuring a particularly reliable fastening. Moreover, with regard to the movement of the window sash relative to the window frame, described in detail below, play can also be minimized by a clamping fixation.

[0020] Particularly with the described force-fit and / or form-fit attachment of the drive module to the upper window rebate, the drive module can be mounted to the window sash without any modifications to the sash itself. No drilling is necessary, and the drive module is very easy to install and remove. Due to its ease of use, which requires no drilling or other modifications, the tilt-and-turn mechanism can be used without restrictions with windows made of various materials such as wood, metal, and plastic.

[0021] The window system according to the invention can therefore be implemented particularly easily with existing tilt windows, including tilt-and-turn windows, that previously did not have a drive mechanism. To then create the described window system, the tilt operating device can be retrofitted as a separate accessory, and complete removal is also possible at any time. Against this background, the tilt operating device can also be used without any problems in rented apartments without requiring any permanent alterations.

[0022] Following the modular approach, the simple assembly and disassembly can also be used to use the tilt operating device on a tilt window for a limited period of time, after which the tilt operating device can be mounted on another tilt window without much effort.

[0023] A simple and, in particular, reversible connection of the tilting mechanism to the window frame is also preferred within the scope of the invention.

[0024] For example, the tension-push device can be connected to the window frame by a connecting element. The connecting element can, in particular, be double-folded, with the connecting element having two right-angled bends in opposite directions.

[0025] Regardless of the specific shape of the connecting element, it is preferred that it be attached to a horizontal frame surface of the window frame. The horizontal frame surface can, for example, run adjacent to the upper window rebate and laterally define the window sash outside the upper window rebate.

[0026] It is particularly preferred if the connecting element is attached to a window fitting or a window fitting receptacle of the window frame. In this context, it is common for the window frame to have window fittings which, when the window sash is closed, interact with typically cylindrical or mushroom-headed locking elements of the window sash.

[0027] For particularly easy installation, it may be possible to remove the existing window hardware from the window frame, allowing the existing screw hole(s) to be used directly for attaching the connecting element. No new drilling is required to connect the connecting element to the window frame. For dismantling, only the removed window hardware needs to be stored and reinstalled.

[0028] Alternatively, it is also conceivable to combine the connecting element with the existing window hardware, to provide adapted window hardware, or to equip the connecting element itself with a functionality of the window hardware. For this purpose, grooves or projections could be provided, for example, which then interact with corresponding locking elements.

[0029] If, in individual cases, the connecting element cannot be positioned in place of a window fitting and therefore no existing screw hole can be used, the connecting element can be fastened in another way, for example with a self-tapping screw. If the window frame has grooves and / or ribs, a clamping fastening may also be possible.

[0030] Preferably, the push-pull element is connected to the connecting element via a detachable coupling. This means, in particular, that the coupling can be easily released by a user without tools. Preferably, manual mechanical actuation is provided, although electromechanical and / or remote-controlled actuation is also conceivable.

[0031] With the coupling disconnected, the tilt window can be operated entirely by hand, and the tilting mechanism is then inactive. In the decoupled state of the pull-push link and connecting element, a tilt-and-turn window, for example, can also be opened in the conventional manner, whereas such movement is not possible when coupled.

[0032] The drive module preferably comprises a drive motor acting on the push-pull element, which may in particular be a simple geared motor. Various electromechanical drive systems with mechanical reduction and / or transmission are known in practice. It should be noted that the speed of the tilting movement is generally not required to be very high, so a comparatively low motor power may suffice. This is especially true because the present invention relates to vertically mounted tilt windows, particularly tilt-and-turn windows, where the opening angle relative to the vertical is generally relatively small, for example, between 10° and 15°.

[0033] In addition to or as an alternative to the previously described detachable coupling connection, the push-pull mechanism can also be designed to have a freewheel. This means that while the push-pull mechanism is connected to the window frame, particularly via the connecting element, it can move relative to the drive module, and in particular, can move freely. A freewheel can be achieved, for example, by making the push-pull mechanism decoupled from the previously described drive motor. With such a freewheel, the window sash can, for example, be manually moved into its tilt position, and it may then be possible to re-engage the mechanism in this position in order to subsequently close the window sash again using the drive module.

[0034] According to one possible embodiment of the invention, the push-pull element is designed as a rack and pinion. The rack and pinion can then be connected to the drive motor, for example, via a gear. Alternatively, various other types of linear drives are also possible. A drive using a linear motor is also fundamentally possible, although in many cases a simple rotary geared motor is sufficient for the described application.

[0035] In a simple embodiment, the tensile-push element is rigidly designed. In this case, sufficient freedom of movement for the rigid tensile-push element must be provided.

[0036] The travel distance of the tilt mechanism can, for example, be between 100 mm and 200 mm, particularly between 110 mm and 150 mm. The specified values ​​refer to the maximum available travel distance; however, depending on the design of the tilt window, a shorter travel distance may be possible.

[0037] Within the scope of the invention, it is also possible to use the control system without utilizing the entire available travel range. When determining a suitable travel range, it can also be taken into account that the tilting actuation device should be usable for different tilt windows, whereby the opening gap achievable in the tilt position, and thus the travel range, can vary.

[0038] The drive module preferably has a housing which, at least when the window sash is closed, at least partially and preferably substantially accommodates the push-pull mechanism. The drive motor, gears, or the like described above are also arranged in this housing.

[0039] The housing should also have a compact form to ensure a high-quality overall impression of the window system and to avoid being perceived as an intrusive element. The housing's height, determined along the vertical axis, can, for example, range between 30 mm and 90 mm. Depending on the design of the window sash, the housing may essentially rest against a surrounding profile of the sash, with the surrounding profile holding the glazing. In such a design, the viewing area exposed by the glazing is either not obstructed or at least not significantly restricted.

[0040] Perpendicular to the extension of the window sash, the housing should also be as compact as possible, generally accommodating the previously described tensile-push element. It may be designed so that the housing, measured from a contact surface on the upper window rebate, has a length of less than 200 mm and, in particular, less than 150 mm.

[0041] It is also conceivable to use designs where the specified length is less than the travel distance of the tilting mechanism. Various configurations are possible to still accommodate the push-pull element.

[0042] For example, the pull-push mechanism of a closed window sash can be deflected relative to its operating direction, at least on one side facing away from the window frame. At least on this side, the pull-push mechanism can be bent or coiled, for instance.

[0043] One possibility is a tension-shear element which, in a straight arrangement, is rigid under thrust, where, for example, individual links interlock and can then bend under tension. Furthermore, the tension-shear element can also be made entirely of a material that can exert a certain amount of thrust but is also bendable or flexible in at least one direction.

[0044] For example, a push-pull mechanism is conceivable, which is flexible on the side facing away from the window frame, with a rigid section attached to the window frame. With a typical tilt mechanism, relatively small push forces are usually required to tilt the window sash from the closed position, starting from the vertical orientation. A shear load occurs particularly at the beginning of the opening movement. Once a slightly larger tilt angle is reached, the weight of the window also acts on the sash, so that at least at the end of the opening movement, the push-pull mechanism is then under tensile stress. During the entire closing movement, a tensile load is generally present.

[0045] In principle, it is also conceivable that the push-pull mechanism is multi-part and telescoping. Suitable examples include nested rod- or sleeve-shaped elements with spiral drive structures.

[0046] Regarding the control of the tilting actuation device, numerous design possibilities arise within the scope of the invention, whereby the drive module usually includes control electronics.

[0047] The drive module can be powered by a permanent power connection, particularly a low-voltage connection. If powered by a power supply unit, familiar standards such as USB can also be used, for which a wide variety of electronic circuits, pre-configured assemblies, and modules are available.

[0048] Additionally or alternatively, an energy storage device in the form of batteries, rechargeable batteries, battery packs, or similar can be provided. It is possible to replace the corresponding energy storage device on the drive module, whereby commercially available batteries or rechargeable cells can be inserted into corresponding sockets. This also offers the advantage that the energy consumption of the drive module is comparatively low, because a relatively small amount of energy is generally sufficient for the described tilting movement from the vertical position.

[0049] Battery packs can be easily replaced using a simple plug-in system, without having to open the housing. Batteries or battery packs can, of course, also be charged inside the housing. A charging request can be indicated to the user by a visual or audible signal. Even if the drive module is inoperable due to insufficient power, the preferably designed detachable coupling and / or a freewheel mechanism for the push-pull element still allow for manual operation.

[0050] The operation of the drive module can be carried out in various ways within the scope of the invention. For example, configurations are conceivable in which the power supply via an external connection is processed as a kind of switching signal. For instance, switching on the power supply can initiate an actuation process, particularly an opening process. A closing process can then be triggered, for example, by a timer. It is also conceivable that an energy storage device in the drive module is charged for the closing process. The actuation of the drive module can then be controlled, for example, by an external timer or similar device.

[0051] The drive module can also be controlled by appropriate control signals, and the drive module can include at least one operating button. For example, such an operating button can be provided on the housing described above. With a simple toggle switch, a ventilation function can be triggered for a predetermined period, whereby, of course, a power supply must be available at least for the duration of the activation and the ventilation process. Such a design with at least one operating button is particularly advantageous if the drive module is permanently powered, for example, by a permanent power connection and / or energy storage device. To provide different ventilation functions, multiple operating buttons can, of course, be provided. Displays, touchscreens, or similar devices are also conceivable.

[0052] Furthermore, the control electronics can include a wireless communication interface. This interface can be used, for example, via a proprietary remote control, or various wireless communication standards can be employed. Communication can also occur via Bluetooth, Wi-Fi, ZigBee, or similar technologies. Operation and control can then be performed by mobile devices, smart home systems, or other electronic devices.

[0053] It may also be provided that the control electronics or a computing device connected wirelessly or via a data line is set up to process status data in order to operate the window sash depending on status data.

[0054] For example, it is known that in buildings, extractor hoods that vent to the outside can only be operated in combination with fireplaces or stoves if the backflow of combustion gases through the extractor hood is prevented. For instance, extractor hoods are known that can only be operated when a window is open, for which appropriate position sensors are used. According to the invention, when an extractor hood is activated, a corresponding control signal can be transmitted to the drive module to actively move the window into the tilt position.

[0055] Additional condition data can be measured, calculated, or predicted. This condition data can include, for example, temperature, humidity, wind, precipitation, particle content, noise level, local weather data, or the like.

[0056] For measured, calculated or estimated temperatures, the tilting actuation device can also be used for temperature adjustment.

[0057] Several methods are conceivable here as well. For example, it is possible to compare indoor and outdoor temperatures. If the outdoor temperature is too high, the tilt mechanism can be deliberately omitted. Then, when the outside temperature cools down in the evening, automatic ventilation can occur to cool the interior.

[0058] Taking precipitation into account can be useful in reducing the risk of moisture ingress in the form of rain or snow.

[0059] Wind data can be used, for example, to optimize certain ventilation scenarios.

[0060] In noisy environments, the window sash can close automatically to protect residents from excessive noise pollution.

[0061] A similar principle applies to the presence of particles. For example, if there is a high particle concentration outside the building, ventilation may be unnecessary. This approach is particularly useful for allergy sufferers when exposure to a specific type of pollen is measured or expected. Conversely, if the particle concentration inside is too high, targeted ventilation may be necessary.

[0062] Determining the humidity level can be particularly useful in sanitary facilities, in order to allow ventilation after showering or other use until the humidity is reduced to a necessary level.

[0063] As mentioned previously, different tilt windows typically have different maximum opening gaps. Therefore, it is conceivable that the travel provided by the drive module is greater than the opening gap. The drive motor can, in principle, be switched off via end stops. However, preferably, or alternatively or additionally, control via the motor current or another load-specific measurement parameter of the drive motor is provided.

[0064] If a predefined or adjustable limit value is exceeded, an automatic shutdown can occur, eliminating the need for mechanical limit stops, toggle switches, or similar devices. This automatic shutdown also ensures pinch protection. Pinching is particularly problematic during closing movements, and in such cases, a slight opening movement may be necessary to release the clamping.

[0065] Even if the window sash is intended to remain open for an extended period, it can be temporarily closed as a kind of test run. This ensures, for example, that the drive module remains operational and is not blocked. In the event of a blockage or malfunction, a warning signal can then be emitted.

[0066] For example, animals like cats can occasionally get trapped in a tilted window and be seriously injured or even killed. During the test drive described, such a situation would be detected and could then trigger a warning signal.

[0067] Additional or alternative safety features are also conceivable. For example, in the event of a power outage, a suitable control system could automatically close the window sash to bring it into a safe position. It goes without saying that sufficient energy for the closing process must be supplied by the previously described energy storage device or another buffer.

[0068] To provide improved protection against tampering with a tilted window sash, a lockable window handle can be installed, for example. Such window handles can usually be easily replaced, allowing for simple removal of the window.

[0069] Various opening positions are also conceivable within the scope of the invention. For example, it is possible to use only a portion of the opening gap provided by the tilt window, and various operating modes with different opening positions are conceivable for this purpose as well.

[0070] Regarding the control of the power supply, further variations and design options arise. For example, an external control module can be provided, which is not directly attached to the window sash or frame, or at least does not necessarily have to be, and which is permanently connected to a power supply. The external control module can, for instance, be located near a power outlet or connected via a cable in a concealed position close to the window. The external control module can then easily be configured for sophisticated data and signal processing, which may include network communication via LAN, WLAN, ZigBee, Bluetooth, mobile communication standards, or similar technologies. The control electronics integrated into the drive module itself can then be designed to respond only to a simple radio signal from the external control module.Within such a design, the energy requirements of the control electronics can be kept low, making a local power supply via rechargeable batteries or accumulators particularly feasible.

[0071] The invention also relates to the previously described tilting actuation device for the window system as a separate assembly. Reference is made to the preceding explanations regarding the possible configurations of the tilting and actuation device.

[0072] The invention further relates to a building arrangement with at least two of the window systems described above. In particular, it can be provided that the at least two window systems are configured for coordinated operation.

[0073] Depending on user requirements, a draft between two window systems can be deliberately avoided or utilized. For example, to protect occupants, alternating operation can be implemented, whereby only one window sash is open at any given time when there are two or more window systems. This prevents drafts from affecting people inside the building, while still providing a degree of ventilation.

[0074] Alternatively, the draft can also be used to increase efficiency during ventilation and, in particular, to reduce energy loss.

[0075] For example, two window sashes can be opened in a coordinated manner to create an airflow and thus enable air exchange. With such an airflow, a relatively rapid air exchange is possible, so that a short ventilation period may be sufficient and the associated energy losses are minimized.

[0076] The invention is explained below with the aid of figures. These show: Fig. 1 a window system with one open window sash, Fig. 2 a window system according to the Fig. 1 with a closed window sash, Fig. 3 a sectional view of the window system, Fig. 4 a partial view of the window system, Fig. 5 and Fig. 6 Details on alternative designs of the window system.

[0077] The Fig. Figure 1 shows a section of a window system with a tilt-and-turn window designed for vertical installation, comprising a window frame 1 and a window sash 2. The window system further includes a tilt-and-turn operating device 3, which has a pull-push element 4 and a drive module 5 for the pull-push element 4. The window sash 2 overlaps the window frame 1 at its upper edge with an upper window rebate 6. This means that, starting from an inside edge of the window, the rebate 6 lies in front of the window frame 1 or, when the window is closed, rests against it. A seal 7 can also be provided there in a known manner.

[0078] The Fig. Figure 1 shows the window sash 2 opened by a tilting movement, which is connected to the window frame 1 at its underside in a known manner. The tilting movement is controlled by the tilting actuation device 3, wherein the pull-push element 4 in the form of a rack is extended from a housing 8 of the drive module 5.

[0079] The drive module 5 has two angled retaining elements 9 which grip the upper window rebate 6. The retaining elements 9 securely hold the drive module 5 to the upper window rebate 6, with the weight of the drive module 5 also contributing to this secure hold.

[0080] Furthermore, it can be seen that the retaining elements 9 on the housing 8 are adjustable, with clamping provided by screws not shown.

[0081] The Fig. Figure 4 shows a diagram in which the window frame 1 has been omitted for clarity. It can be seen that the upper window rebate 6 is clamped between the clamping surfaces of the retaining elements 9 and a corresponding surface on the housing 8. This ensures not only a particularly secure and reliable hold but also a fixed position. The drive module 5 is thus attached to the upper window rebate 6 by friction and form-fitting means.

[0082] Accordingly, the drive module 5 can be mounted on the window sash 3 without any modifications and can be removed without leaving any residue. No drilling, gluing, or other modifications are necessary. The tilt operating device 3 is therefore particularly well-suited for retrofitting and can be easily removed, for example, in rented apartments. Users are also free to use the tilt operating device 3 on different tilt windows.

[0083] The Fig. Figure 2 shows the closed window sash 2, with the pull-push device 4 in the form of the rack retracted and located largely inside the housing 8.

[0084] Further details of the window system can be derived in particular from the Fig. 3 and Fig. 4, wherein the Fig. 3 shows a cross-sectional view and, in the case of the previously briefly mentioned Fig. 4 is omitted for the sake of clarity of window frame 1.

[0085] Especially in the Fig. 3 and Fig. Figure 4 shows that the tensile-push element 4 is connected to the window frame 1 by a connecting element 10. The connecting element 10 is double-folded and connected to a horizontal frame surface of the window frame 1.

[0086] In this context, the Fig. 4. A locking element 11 is attached to the window sash 2, which was originally intended for locking with a window fitting (not shown). The window fitting has been removed for mounting the tilt operating device 3, with the screw hole of the window fitting now being used for a fastening screw 12, with which the connecting element 10 is attached to the window frame 1 (see Figure 4). Fig. 3).

[0087] Regarding the window frame 1, a completely reversible and residue-free dismantling is also possible, requiring only that the window hardware be retained and reinstalled during dismantling. Both the installation and removal of the entire tilt operating device 3 are extremely simple and can be easily carried out even by laypersons without extensive DIY skills.

[0088] With regard to the window shown only in part, it is known that a window handle is provided for switching between a closed position, a tilt function, and a pivot function. It is understood that, within the scope of the invention, the window handle is to be moved into the tilt position by the tilt actuation device 3 for the automatic drive of the window sash 2.

[0089] The figures show that the push-pull element 4 is connected to the connecting element 10 via a detachable coupling 13. The coupling 13 has a drive pin 14 made of magnetizable material.

[0090] In the coupled state, the drive pin 14 engages a ring magnet 15 arranged on the connecting element 10. A bar magnet 16 is located below the drive pin 14 and is rigidly connected to a decoupling lever 17.

[0091] If, starting from the in Fig. In the closed position of the window sash 2 shown in Figure 3, when the decoupling lever 17 with the attached bar magnet 16 is pulled downwards, the drive bolt 14 is deflected to such an extent that the coupling connection 13 between the pull-push means 4 and the connecting element 10 is released. The window sash 2 can then be moved independently of the tilt operating device 3 and, in particular, pivoted open about a vertical axis. When the window sash 2 is then back in the closed position, the coupling connection can be re-established by actuating the decoupling lever 17 in the opposite direction.

[0092] The arrangement of the drive pin 14 between the ring magnet 15 and the bar magnet 16 is advantageous so that the actuating movement of the tilting mechanism 3 can be easily executed despite the provision of the coupling connection 13. Specifically, when the pull-push element is driven by a drive motor 19 via a gear 18, the bar magnet 16 separates from the drive pin 14 due to the lateral movement, which is then securely held in position by the ring magnet 15. The described release of the coupling connection 13 can only occur when the window sash 2 is in the closed position.

[0093] In the illustrated embodiment, the gear 18 with the drive motor 19 is arranged on a support 20. Within the scope of the described configurations, this support 20 is movable, in particular pivotable, in order to be able to lift the gear 18 off the tension-push element 4 in the form of the rack.

[0094] For this purpose, an actuating lever 21 is provided, whereby the actuating lever 21 enables a kind of freewheeling of the pull-push element 4. By actuating the actuating lever 21, the pull-push element 4 is disengaged from the gear 18, so that the window sash 2 can then be tilted in the conventional manner. Such a tilting function is useful, for example, if the tilting operating device 3 is malfunctioning, is intentionally not to be used, or if a user is unfamiliar with the tilting operating device 3.

[0095] In the illustrated embodiment, an energy storage device 22 is provided inside the housing 8 of the drive module 5, which powers the drive motor 19 via a [connection / connection / etc.] located in the Fig. 4. The control electronics 23 shown are driven by the energy storage device. The energy storage device 22 can comprise batteries or accumulators in a known manner, and an additional or alternative power connection, in particular a low-voltage connection, is also possible. Such a power connection can replace or supplement the energy storage device 22.

[0096] In the case of the energy storage device 22, it is conceivable that the corresponding batteries or accumulators can be replaced or charged within the housing. If the energy storage device is configured as a battery pack, such a component can also be replaced and charged externally. In contrast to the illustrated embodiment, such a battery pack can then also be arranged on the outside of the housing or in a freely accessible housing recess.

[0097] The control electronics 23 enable various operating modes, already described in the general description, which will not be discussed further in this figure description. In addition, an energy-saving mode is also possible, in which, for example, the drive motor 19 is de-energized during idle phases and only a portion of the electronic components and, if applicable, only a portion of the control electronics 23 are active. Such operating states are also known as standby or similar modes.

[0098] As indicated in the figures, the housing 8 can also be equipped with at least one control button 24, which can be linked to a specific function. For example, as a simple ventilation function, pressing the control button 24 can open the window, and then after a predetermined time, for example after 15 minutes, the window sash 2 closes again. Such a timer can also be triggered, for example, if the control button 24 is pressed while the window sash 2 is open.

[0099] The tilt actuation device 3 according to the invention is not only easy to install and can be removed without leaving any residue, but is also highly functional despite its comparatively simple design and can be retrofitted as an accessory. Furthermore, the tilt actuation device 3 is compact overall. As can be seen from the figures, the height of the housing 8 can be kept so low that the housing 8 rests essentially along a profile 25 of the window sash 2 along the vertical direction, which supports a pane 26 of the window sash 2. The viewing area exposed by the pane 26 is then not, or at least not significantly, restricted by the tilt actuation device 3.

[0100] According to the in the Fig. In the embodiment shown in Figures 1 to 4, the pull-push element 4 is rigid in the form of a rack, and when the window sash 3 is closed, the pull-push element 4 is arranged essentially within the housing 8. Accordingly, the length of the housing 8, measured from the window rebate 6, must be sufficiently long, with the travel provided by the tilt actuation device 3 being, for example, between 100 mm and 200 mm.

[0101] In principle, designs are also conceivable in which the housing 8 has a length perpendicular to the window sash 2 or the profile 25 that is shorter than the adjustment path.

[0102] The Fig. Figure 5 shows a possible embodiment in which the push-pull element 4 is also designed as a type of rack, but this has a front rigid section 27 and a flexible section 28 facing away from the window frame 1. Accordingly, the housing 8 can be made even more compact.

[0103] The in Fig. The embodiment shown in Figure 5 is based on the understanding that a shear load on the tensile-shear element 4 is particularly relevant at the beginning of the opening movement of the window sash 2. The rigid section 27 is suitable for applying the necessary shear. As the tilt of the window sash 2 increases, the weight force acting in the opening direction must be taken into account, so that a lesser degree of shear must be exerted, or the tensile-shear element 4 may even be subjected to a tensile load despite the opening movement. The flexible section 28 is sufficient for such movement.

[0104] In purely schematic terms, in the Fig. 6 indicates that the tensile-push device 4 can also be designed to be telescopic.
