Description

[0001] The invention relates to a tilt drive device for a rotatable and tiltable sash of a window, a door or the like with the features in the preamble of the main claim.

[0002] FR 3029235 A shows such a tilt drive device. It can open and close the window by tilting the sash around a horizontal axis. For this purpose, a pin of the window lock is coupled to the tilt drive device via a pivoting arm with a lock at the end and a ring. The tilt drive device has a release mechanism that decouples the sash from the tilt drive device, allowing the window sash to be manually rotated around the vertical axis.

[0003] EP 1 865 130 A1 shows a tilt drive device in which the electric drive arrangement and the coupling device are arranged together on the wing and are permanently coupled to the wing.

[0004] Other tilt drive devices are known from practice. To manually tilt the sash, the opening mechanism is released from the sash and remains in its rest position.

[0005] DE 20 2012 001 475 U1 shows a connecting rod drive located at the bottom of the sash, close to the horizontal tilt axis. This drive is permanently connected to the drive rod of the sash locking mechanism and to a tilting mechanism for tilting the sash. The connecting rod drive can tilt the sash using a motor. This mechanism utilizes the window's existing tilting mechanism, which is already provided for manual tilting and is coupled to the window handle and the connecting rod drive by a mechanical guide. Due to its fixed position on the sash, the connecting rod drive can be moved around the vertical axis of rotation when the sash rotates, while its connection to the connecting rod remains intact.

[0006] The invention solves this problem with the features in the main claim.

[0007] The claimed tilt drive technology, ie the tilt drive device and the method, have several advantages.

[0008] The tilt drive device has its own drive, preferably motorized and remote-controlled, and its own opening mechanism. It can be attached or installed during the manufacture of tilt-and-turn sashes and windows, doors, flaps, or similar equipped with them. Thanks to its self-contained design, it can also be retrofitted to existing sashes or replaced with another tilt drive device. The tilt drive device can also be used on sashes that are only tiltable but not pivotable.

[0009] The tilt drive device has the advantage of offering significantly expanded operating options and increased operating comfort.

[0010] The coupling device of the tilt drive device establishes a coupling connection between the sash, in particular the sash locking mechanism and / or a guide permanently mounted on the sash, and the tilt drive device, at least when the sash is tilted about one bearing axis, in particular the tilt axis. This occurs both during manual tilting using the actuator and during automatic or remote-controlled tilting using the tilt drive device. The tilt drive device, in particular its extension mechanism, moves with each tilting movement of the sash.

[0011] The coupling connection remains intact in all tilt positions and also in both end positions of the sash's tilt movement. The coupling connection transfers forces and movements from the tilt drive device to the sash and vice versa. The coupling connection preferably acts as a positive locking mechanism or in another way.

[0012] Tilting or the tilting movement means both the tilting or tilt opening, as well as the tilting or tilt closing of the sash.

[0013] On the other hand, the coupling device has a free passage that separates or decouples the tilt drive device from the sash, in particular from the sash locking mechanism or a guide fixed to the sash, when the sash is to be opened by rotating it around the other bearing axis. The sash can thus be opened and closed manually without hindrance by rotating it. The sash locking mechanism is moved by the actuator into an intermediate position, in which the free passage of the coupling device is also opened.

[0014] In all cases, the manually operated locking and unlocking movement of the sash lock is transmitted to the tilt drive mechanism and its coupling device. Conversely, the tilt drive mechanism drives the sash lock via the coupling device and moves it to tilt the sash from its rest position and to lock the sash when it has returned to its rest position.

[0015] In the locked, closed position of the sash, the coupling device can establish an additional coupling connection between the tilt drive device and the sash, in particular the sash locking mechanism. This is advantageous for the aforementioned driven movement transmissions from the rest or closed position to the tilt position and to the intermediate position for rotating the sash, as well as back in the opposite direction.

[0016] When tilting a closed and locked window, the sash lock or its drive rod moves, for example, linearly between a locked end position for the rest or closed position of the sash via an unlocked intermediate position for rotating the sash to the other unlocked end position for tilting the sash.

[0017] The coupling device and the coupling connections can transmit forces and movements between the tilt drive mechanism and the sash, in particular the sash locking mechanism and / or a guide permanently mounted on the sash. Force and displacement transmission is possible in the opening or tilting direction of the sash, as well as in the deviating movement or locking direction of the sash locking mechanism. The tilt drive mechanism can move or actuate the sash locking mechanism using drive force.

[0018] The tilt drive device can unlock and tilt the sash from the locked rest or closed position automatically or remotely. The tilting can occur to a predefined, fully open end position or to a selectable, partially open intermediate position. The tilt drive device can also tilt the sash in again automatically or remotely from any tilt position and lock it in the rest or closed position. Conversely, when manually operated from any tilt position, the sash can move and engage the tilt drive device through the tilting sash movement and the movement of the sash lock.

[0019] The claimed tilt drive technology, in particular the coupling device, is designed to enable optional tilting of the tilted sash by means of the tilt drive device or manually using the actuator. Closing of the tilted sash is also possible either manually or by power. A previously manually tilted sash can be closed automatically or remotely using the tilt drive device, or a sash previously tilted by the tilt drive device can be closed manually. This is possible safely and without delay by maintaining the coupling connection in all tilt positions.

[0020] The claimed tilt drive technology offers the particular advantage of expanded sash operating options. The freedom to choose between tilt opening and closing the sash manually or using the preferably motorized tilt drive significantly increases operating convenience. An operator who wants to close the tilted sash does not need to know whether the tilt movement was previously performed manually or by the tilt drive.

[0021] On the other hand, an operator can open the sash unhindered by rotating it around the other bearing axis. When closing the rotated sash, the free movement can be removed, reestablishing a coupling connection. Upon manual locking, the tilt drive mechanism and its opening mechanism are returned to their original position. On the other hand, the rotated sash can be closed and immediately tilted. This also reestablishes the coupling connection, allowing optional tilting either manually or using the tilt drive mechanism.

[0022] The opening device can be connected directly or indirectly to the sash, in particular to the sash locking mechanism. With a direct connection, the opening device can directly engage and be connected to a locking element, e.g., a locking pin, of the sash locking mechanism. The locking element can also form a coupling element of the coupling device. The opening device can have an output element, which can be connected directly or indirectly to the sash locking mechanism.

[0023] The indirect connection of the tilt drive device, in particular the opening device, to the sash locking mechanism can be achieved using an adapter. The adapter has independent inventive significance. It can also be used with coupling devices without the free passage. The adapter enables expanded design and functional coupling options.

[0024] The adapter enables simple and cost-effective adaptation of the tilt drive device to different sashes and sash locking systems. The tilt drive device can be standardized and used universally on any sash and sash locking system.

[0025] The adapter, preferably in a strip shape, can be attached to the sash locking mechanism, or can be attached there. This fixed connection allows the adapter to be driven and moved when the sash locking mechanism is actuated. Conversely, the adapter can transmit drive movements from the tilt drive device to the sash locking mechanism, driving the latter and, if applicable, the actuator. The adapter can move forwards and backwards in the locking direction. This is also possible with other coupling devices arranged between the opening devices and the adapter without free movement.

[0026] The adapter can work with a guide that can also be attached to the sash. The guide can be part of the tilt drive mechanism. A fixed guide can also work with the tilt-opening and tilt-closing mechanism.

[0027] The coupling device establishes the coupling connection between the tilt drive mechanism, in particular its extension mechanism, and the sash. In particular, a coupling connection can be established between an output element of the extension mechanism, e.g., a pin at the end of a link or a pivot lever, or an end link of a push chain, and the sash locking mechanism and / or a sash-fixed guide. The coupling connection can be established directly with the sash locking mechanism or indirectly via the adapter.

[0028] The tilt drive device has a separating element that prevents a restrictive drive connection between the drive and the opening device when the tilted sash is manually closed. This allows the sash to be closed manually without significant resistance. The separating element can also prevent a restrictive drive connection when the sash is manually tilted open, as well as during other manual actuation movements of the sash locking mechanism, e.g., when locking and unlocking the closed sash.

[0029] The separating device only establishes the drive connection upon a command input or when the tilt drive device's drive is activated. It automatically disconnects the drive connection when the tilt end position is reached and / or upon a stop command or a movement stop in an intermediate tilt position. In the event of a power failure, especially the power supply, the drive connection can also be automatically disconnected.

[0030] The separating element can also serve security purposes, particularly as a burglar alarm. It can intentionally establish the drive connection and, through internal resistance in the tilt drive mechanism, prevent or at least impede unauthorized operation of the manual actuator and the sash locking mechanism. This can be achieved, for example, by activating an alarm system.

[0031] The separating device can be designed in different ways. For example, it can be a coupling that disconnects the extension mechanism from the tilt drive during manual opening and closing, and then reconnects it. The coupling can be controllable.

[0032] In another embodiment, the separating means can be designed as a movement thread of a gear connected between the drive and the tilting mechanism. Another form of separating means reduces or eliminates the internal resistance of the tilting mechanism's drive during the manually imposed dragging movement from the outside. Furthermore, other structural and functional configurations are possible.

[0033] The separating means can be designed in various variants in such a way that, in the closed position of the tilted wing, it re-establishes the normal drive connection between the said drive and the opening device.

[0034] The drive technology for the tilt drive device can be designed in different ways. The tilt drive device preferably has a motorized drive that drives at least the opening device when the sash is tilted. The drive can also drive the adapter. However, it is also possible for the drive to drive the opening device and the adapter separately. The drive can also be designed as a derived drive or a follower drive. Depending on the design, the drive can have a common drive means or separate drive means for the opening device and the sash locking mechanism, in particular the adapter. At least one drive means is present. If the drive has said separate drive means, these are arranged in a common housing.

[0035] The one or more drive means can be formed by a controllable motor, e.g., an electric motor, which, if necessary, is preceded by a transmission. The electric motor can be operated, for example, with direct current and low voltage or in another way. Alternatively, a drive means can be designed in a different way.

[0036] The tilt drive mechanism, which drives the opening mechanism and the sash locking mechanism, especially the adapter, and the opening mechanism can be arranged on a common housing. This ensures a compact design of the tilt drive mechanism and facilitates installation.

[0037] The drive is preferably remotely controllable. The tilt drive device comprises a controller and at least one interface. The interface can be used for wired or wireless communication and for the input and output of control signals, status information, and the like. The tilt drive device can be operated by an operator using a switch, a remote control, or the like. Alternatively or additionally, it can be controlled by a higher-level control system of a fire alarm system, ventilation system, alarm system, or the like.

[0038] The tilt drive device can have a detection device with which one or more operationally relevant parameters, in particular a position and / or a travel of the sash and / or the tilt drive device and / or the sash locking mechanism, can be detected. The detection device can be connected to the controller and, if necessary, to the interface. The detection signals can be reported to a higher-level controller.

[0039] The coupling device can have one or more coupling points between the tilt drive mechanism and the sash, in particular the sash locking mechanism and, if applicable, the sash-fixed guide. Preferably, several coupling points, e.g., two or three, are provided. This is particularly advantageous for creating the clearance. The number, arrangement, and function of the coupling points can vary.

[0040] A coupling connection can be established and then opened again at each of the coupling points. The coupling connection can be established directly between the tilt drive device and the sash locking mechanism or indirectly via the adapter. A coupling connection can also be established between the tilt drive device and a guide fixed to the frame.

[0041] A coupling point can be arranged between the opening mechanism and the sash, in particular between an output element of the opening mechanism and the sash locking mechanism or adapter. The movement can be transmitted at this coupling point when the tilted sash is tilted and closed.

[0042] If necessary, an additional coupling point can be arranged between the drive of the tilt drive device and the adapter.

[0043] Furthermore, a coupling point can be arranged between the extension device, in particular an output element of the extension device, and a guide of the adapter fixed to the sash. This can ensure increased coupling strength and better force transmission and force support on the sash.

[0044] It is also possible to provide several, in particular two, coupling points on the opening device. One coupling point is arranged between the opening device and the sash locking mechanism or the adapter, and another coupling point is arranged between the opening device and a guide fixed to the sash. The several, in particular two, coupling points can be arranged at end regions of the opening device that are spaced apart from one another in the locking direction relative to a closed position of the tilt drive device and the sash.

[0045] The coupling device can have an exit opening pointing in the extension or tilt direction. This can form the access passage. It can allow the coupling connection to be opened by separating the coupling elements.

[0046] The coupling device can have a locking device acting in the extension or tilt direction. This can have different designs, arrangements, and functions.

[0047] The locking device can be assigned to a coupling point and secures, for example, the coupling connection during tilting and subsequent closing of the sash. The locking device can also prevent unwanted rotational opening of the sash, e.g., due to wind pressure, if the tilt drive mechanism moves the sash lock back and forth between its closed and fully open end positions, thereby overrunning the intermediate position for the aforementioned clearance. If the sash lock is manually operated and the sash is intended to be rotated open, the locking device may be ineffective. The locking device can have a positive locking effect. It can also have a spring-loaded effect.

[0048] The locking device can be activated and deactivated. When activated, it can secure the coupling connection during movement of the sash locking mechanism. When deactivated, the coupling connection can be released and opened, for example, for free passage and rotation of the sash. Deactivation is also possible at a coupling point between the drive and a separately driven adapter for tilting purposes.

[0049] The locking device can be deactivated by an actuating device, e.g., a spring. The locking device can also be activated and deactivated by another actuating device, e.g., a motorized drive. In the cases mentioned, this can occur automatically, for example. An actuating device can be designed to provide low-resistance movement of the manual actuator in an intermediate position for turning the sash. In the closed and fully open end positions of the sash locking mechanism, the resistance is higher and can prevent unwanted opening of the coupling connection.

[0050] In another embodiment, the locking device can have a fixed stop on the adapter and a controlled extendable stop on a frame-fixed housing of the tilt drive device. The extendable stop can be actuated together with the drive. The locking device is activated and deactivated when the drive of the tilt drive device of the drive connection is activated. It acts during the motorized adjustment of the sash lock and the adapter and, when the intermediate position for release is exceeded, prevents the sash from rotating and opening undesirably, e.g., under the influence of wind, by overlapping the stops. The locking device can be deactivated when the sash lock is actuated manually.

[0051] The coupling device can have several, in particular two, interacting coupling elements at each coupling point. The coupling elements preferably interact in a form-fitting manner. Other interaction possibilities are also possible, e.g., through force or frictional engagement.

[0052] The interacting coupling elements can be movable relative to each other transversely to the opening or tilting direction, or in the locking direction. Alternatively, they can be immobile relative to each other and act in a coupling action. For the rotation of the sash and the release of the door, the coupling elements can also be movable relative to each other in the opening or tilting direction. The exit opening and the locking device can be arranged on interacting coupling elements that have a suitable shape for this purpose.

[0053] The locking device has locking elements, e.g., on the interacting coupling elements or at other locations. These are preferably positive locking elements. The locking elements can be formed, e.g., by undercuts and / or a spring clip or a stop bar and a locking pin.

[0054] The locking elements can be brought into engagement with each other by the aforementioned relative movement between the coupling elements. In another embodiment, they can be brought into preferably positive engagement by, for example, a controlled actuating device. The locking elements thus secure the coupling connection at the aforementioned coupling point against forces acting in the extension or tilt direction that attempt to open the coupling connection.

[0055] The locking device can operate alone or in combination with the sash locking mechanism. To create the free passage, the locking effect can be canceled by the adjusting device. The free passage can also be created by a spring clip opening.

[0056] There are various options for the design and arrangement of coupling elements. Preferably, positively interlocking coupling elements in the form of claws or mouths are used, with pins engaging in the extension or tilt direction. In another embodiment, coupling elements can be designed as drivers and, in the engaged position, as receivers that positively enclose the driver.

[0057] Interacting coupling elements can be arranged on the adapter on the one hand and on an output element of the extension device on the other. The output element can be, for example, a pin at the end of a link or pivot lever, or a chain end piece. Interacting coupling elements can also be arranged on the one hand on an output element of the extension device and on the other hand on a guide of the adapter. This can, for example, support a coupling connection between coupling elements on the adapter and on the said output element.

[0058] An arrangement of interacting coupling elements is also possible on an output element of the extension device and on a separate leaf-mounted guide. Interacting coupling elements can also be arranged on the adapter on the one hand and on a drive element, in particular a drive pin, of the drive on the other. Furthermore, an arrangement of several, in particular two, coupling elements is possible at spaced end regions of the extension device on the one hand and on the adapter and a leaf-mounted guide on the other. This has advantages for a particularly compact and stable design of the tilt drive device.

[0059] The deployment mechanism can be designed in various ways, e.g., as a linkage, a guided pivot lever, or a rigid push chain. The push chain can, in particular, have a rigid back. Other configurations of the deployment mechanism are also possible.

[0060] A guided pivot lever enables a compact, resilient, and particularly reliable design. It is preferably elongated and can have the aforementioned multiple, particularly two, coupling elements at its ends for a coupling connection with the adapter on the one hand and the frame-mounted guide on the other. A single drive is sufficient for the extension movement of the pivot lever and the linear movement of the adapter or the sash locking mechanism.

[0061] In a particularly advantageous embodiment, the coupling elements on the pivot lever are each designed as pins. They interact with a jaw-like or slot-like coupling element on the adapter on the one hand and on the frame-fixed guide on the other. The jaw-like coupling element on the adapter can be U-shaped and can have an outlet opening for the release. This design is kinematically advantageous. It enables particularly secure opening and subsequent closing of the coupling connection for sash rotation.

[0062] The tilt drive technology is suitable for any rotating and tilting sash of a window, door, flap or the like. The invention also relates to the sash equipped with a tilt drive device or to a window, door, flap or the like formed therewith.

[0063] The coupling device can establish and, if necessary, release multiple, possibly different coupling connections. This can, for example, be a coupling connection between the tilt drive device and the sash locking mechanism, and another coupling connection between the tilt drive device and a sash-fixed guide.

[0064] The projection device can be guided on the housing of the tilt drive device so that it can move, in particular slide, along the locking direction. It can also be guided so that it can move, e.g., pivot, in the projection or tilt direction. Due to its longitudinal mobility, it can follow the movements of the sash locking mechanism, whereby the aforementioned coupling connection is maintained. The guide of the projection device can prevent transverse movement or pivoting of the projection device over most of the displacement path. This applies to the displacement path of the sash locking mechanism and the projection device between one locked end position, via the unlocked intermediate position, up to just before the other unlocked end position for tilting the sash.

[0065] Further advantageous embodiments of the claimed tilt drive technology are mentioned below, which can be used individually or in combination.

[0066] The tilt drive device can have the following configurations.

[0067] The adapter can be designed in the shape of a strip and aligned along the locking direction and, if necessary, connected to a guide.

[0068] A coupling point of the coupling device can be arranged between the drive of the tilt drive device and the adapter.

[0069] The coupling device can have an activatable locking device acting in the opening direction or tilting direction, which secures the coupling connection when the sash is tilted and closed.

[0070] The locking device can secure the coupling connection during movement of the wing lock in its locking direction.

[0071] The locking device may have an actuating means, in particular a spring, for deactivating the locking device for the release.

[0072] The interacting coupling elements of the coupling device can each be movable relative to each other transversely to the extension direction or tilting direction.

[0073] The outlet opening of the coupling device for the free passage and the locking device can be arranged on cooperating coupling elements of the coupling device.

[0074] The locking device can preferably have positive locking elements on cooperating coupling elements of the coupling device.

[0075] The actuating means of the locking device can be arranged between cooperating coupling elements of the coupling device.

[0076] The force effect of the locking device can be adapted to a low-resistance movement of the manual actuator of the turn-tilt fitting in its operating position for turning the sash.

[0077] The coupling elements of the coupling device can be designed as interlocking drivers and receivers, in particular pins and claws or mouths.

[0078] Interacting coupling elements of the coupling device can be arranged on the one hand on the adapter and on the other hand on an output element of the extension device.

[0079] Interacting coupling elements of the coupling device can be arranged on the one hand on the adapter and on the other hand on a drive element or drive pin of the drive of the tilt drive device.

[0080] Interacting coupling elements of the coupling device can be arranged on the one hand on an output element of the extension device and on the other hand on a guide of the adapter.

[0081] An output element of the extension device can be designed as a coupling element.

[0082] The deployment device can be guided so as to be movable along the locking direction as well as in the deployment or tilting direction, in particular so as to be linearly displaceable and pivotable.

[0083] The guide of the extension device can prevent a transverse movement or pivoting out of the extension device over most of the movement path running along the locking direction, in particular the displacement path.

[0084] The coupling device can be designed to establish a coupling connection between the opening device and the wing in an opening or tilting direction of the wing and in a deviating, preferably linear, locking direction of the wing locking of the wing.

[0085] The tilt drive device can have a tilting mechanism designed as a pivoting lever. The pivoting lever can have a lever bearing that interacts with a guide rail on the housing. It can have an elongated shape. An angled lever shape with lever arms of different lengths and aligned transversely to each other is possible.

[0086] The link guide can guide the opening device, which is designed as a pivoting lever, in a linearly displaceable manner along the locking direction and pivotally at the end of the displacement path to tilt the sash.

[0087] The longer lever arm of the opening device, which is designed as a pivoting lever, has a preferably curved shape and a guide slot which engages with a drive pin of the tilting drive device.

[0088] The guide slot can have a longer, preferably curved slot section and a subsequent straight slot section at the free end of the lever arm.

[0089] The guide slot may have a step at the end transition of the straight slot section into the long slot section.

[0090] The pivot lever can have a coupling element at each end pointing in the locking direction.

[0091] The pivot lever can have a pin-shaped coupling element at each of its ends pointing in the locking direction.

[0092] A locking device can be arranged in the outlet opening, which is designed as a spring clip and has an undercut clip opening that points towards the outlet opening.

[0093] The adapter can have adapter plates lying on top of one another with keyhole-shaped and differently undercut through openings, which are designed for a positive connection with locking elements of the sash locking mechanism.

[0094] The tilt drive device can have a guide that is mounted or fixed to the leaf and is designed as a slotted hollow guide profile for guiding a drive element of the opening device.

[0095] The drive of the tilt drive device can comprise a motor and an elongated drive means, in particular a threaded spindle, which has an output member, in particular a spindle nut, with a drive element, in particular a drive pin, which is connected to the extension device.

[0096] The drive connection between the propellant and the drive element can be closed and separated by means of a controllable separating means, preferably designed as a coupling.

[0097] A wing with the tilt drive device can have the following configurations.

[0098] The sash locking mechanism can be connected to the actuator of the turn-tilt fitting and have a drive rod with locking elements running around several sides of the sash.

[0099] The sash bearing can be connected to the actuator of the turn-tilt fitting and can have a scissor bearing as well as a tiltable corner bearing.

[0100] The tilt drive device can be arranged separately and at a distance from the sash bearing.

[0101] The tilt drive device can be arranged on a wing side, in particular the upper or lower side of the wing, which is opposite the bearing axis intended for tilting.

[0102] The invention is illustrated schematically and by way of example in the drawings.

[0103] The invention relates to a tilt drive device (14) and a method for a rotatable and tiltable wing (3) of a window (1), a door, a flap or the like. The invention further relates to a rotatable and tiltable wing (3) with a tilt drive device (14) and to a window (1), a door, a flap or the like with such a wing (3) and a tilt drive device (14).

[0104] Figure 1 and 2show a window (1) in front and side views, which has a pivoting and tilting sash (3) with a surrounding stationary frame (2). A tilt drive device (14) for the sash (3) is arranged on the window (1). The window (1) can alternatively be designed as a door, flap, or any other type of opening closure, e.g., for a building opening.

[0105] The wing (3) can be tilted about a horizontal bearing axis (5), located, for example, on the underside. The bearing axis (5) is also referred to as the tilting axis. The wing (3) can also be rotated about another vertical bearing axis (6). This bearing axis (6) is also referred to as the rotation axis. In the embodiment shown, the bearing axes (5, 6) have a horizontal or vertical orientation. Depending on the installation position of the wing (3), the axis position can also be oriented differently.

[0106] The sash (3) has a tilt-turn fitting (7) that enables tilting and rotating movements. The tilt-turn fitting (7) has a manual actuator (10), e.g., a rotating handle, and a connected and operable sash lock (12).

[0107] The sash lock (12) consists, for example, of a drive rod (11) which is arranged on at least one side of the sash. The drive rod (11) is preferably arranged circumferentially on several sides of the sash, e.g. by means of corner deflections. One or more locking elements (13) are arranged on the drive rod (11) and interact with counter-locking elements on the frame (2) when the sash (3) is in the closed position. The counter-locking elements are not shown for the sake of clarity. The locking elements (13) are, for example, mushroom-shaped pins which engage in receiving grooves on the frame (2). The drive rod (11) and the locking elements (13) can be moved back and forth in a locking direction (20) by means of the actuator (10). Figure 27 also shows parts of the wing locking mechanism (27) on a wing (3).

[0108] The sash (3) or the turn-tilt fitting also has Figure 1 and 2a sash bearing (4) for the bearing axes (5, 6). The sash bearing (4) can also be connected to the drive rod (11) and can be acted upon by the actuator (11) in order to create the appropriate bearing configuration for tilting and turning the sash (3) as required. The sash bearing (4) has, for example, a scissor bearing (8) and a corner bearing (9). The scissor bearing (8) is arranged, for example, on the upper side of the sash (3) and has an extension scissor or another suitable bearing element which enables tilting about the tilt axis (5) on the other side of the sash. The corner bearing (9) is arranged on the tilt axis (5) and the rotation axis (6). It is located on the lower edge of the sash.

[0109] The tilt drive device (14) is preferably arranged on the wing side opposite the tilt axis (5), e.g., on the wing top side. The tilt drive device (14) can also be arranged on one of the upright wing sides oriented transversely to the tilt axis (5), e.g., on the Figure 1 right side of the wing opposite the actuator (10).

[0110] The tilt drive device (14) has its own drive (21) and its own projection device (26), which can be connected to the sash (3), in particular to the sash lock (12). The drive (21) is preferably recessed into the frame (2). The projection device (26) is located in the rebate area between the frame (2) and the sash (3). Figure 2 illustrates this arrangement. The extension device (26) in the extended state causes the Figure 2tilting of the sash (3) as shown and closes the sash (3) again when retracted. The opening device (26) can be designed and / or mounted to be bend-tolerant or tilt-tolerant.

[0111] Figures 3 to 13 , Figures 14 to 22 , Figures 23 to 26 , Figures 27 to 51 and Figures 52 to 60 show different variants of the tilt drive device (14).

[0112] The tilt drive device (14) has a coupling device (16) for coupling to the sash (3). Furthermore, an adapter (17) is provided, which can be attached to the sash locking mechanism (12) or is attached thereto and is movable with it. In the aforementioned variants, different embodiments of the drive (21), the coupling device (16), the adapter (17), and the extension device (26) are shown.

[0113] The adapter (17) has a flat strip (34) in each of the various variants and is aligned along the local locking direction (20). The adapter (17) is firmly connected to the locking device (12), in particular the drive rod (11), by means of fastening elements (35), e.g., pins or screws. The adapter (17) is preferably located between mutually spaced locking elements (13).

[0114] A guide (36) may be provided for the adapter (17), which, for example, has one or more slots for a fastening element (35). The guide (36) may be formed as a sheet metal or steel strip and may be attached to the wing (3) in a suitable manner. It may, for example, be Figure 2be arranged above a groove in the sash rebate and above the drive rod (11) located in the groove. The strip (34) or the adapter (17) is arranged outside or on the guide (36). The adapter (17) or the strip (34) can have the same width as the guide (36). Figure 2 This arrangement is shown.

[0115] The opening device (26) and the drive (21) are located on the window (1) above the adapter (17). Figure 1 and 2 show this arrangement. In the first variant explained below, the arrangement is reversed to make the details easier to see.

[0116] In the first variant of Figures 3 to 13The tilting drive device (14) comprises a housing (14') with a drive (21) arranged therein (not shown in detail). The drive (21) may comprise one or more drive means (22), which are preferably designed as motors, in particular as a controllable electric motor with a pre-connected gear. This may be, for example, a DC motor with a low voltage of, for example, 24V. The drive (21) and the housing (14') are, for example, according to Figure 1 and 2 recessed into the frame (2). The opening device (26) is located on the outside of the housing (14').

[0117] In the first variant, the extension device (26) is designed as a linkage mechanism (27). It has a linkage (28) connected to the drive (21), in particular the drive means (22), which is rotatably connected to a non-driven linkage (29) and displaceably connected by means of a linkage slot (51). The free linkage end (30) of the driven linkage (28) forms the output element (15) of the extension device (26), which interacts with the wing lock (12) via the adapter (17) in the manner described below.

[0118] The driven link (28) can be moved along the locking direction (20) and rotated at the end of the movement. This is achieved, for example, by a guide slot (48) arranged parallel to the locking direction (20) in the housing (14') and a drive pin (24) guided therein, wherein the Figure 3 by its rotational axis symbolized drive pin (24) from the drive (21) in the direction of the arrow according to Figure 3 is applied and displaced. The driven link (28) can be rotated during the displacement movement by means of the link (29) rotatably mounted on the housing (14'). In the drawings, the displacement movement along the locking direction (20) is directed from the right, from the locked end position with the sash (3) closed, to the left, into the other end position for tilting the sash (3).

[0119] At the front end of the handlebar (30) or at the output element (15) there is a Figure 13 shown pin is arranged, which on the one hand represents a coupling element (39) of the coupling device (16) explained below and on the other hand projects downwards from the link (28) and engages in an upwardly open guide slot (49) on the housing (14'). At the end of the guide slot (49) arranged parallel to the locking direction (20), a lateral slot opening (50) is arranged.

[0120] When the wing (3) is tilted about the tilt axis (5) by means of the drive (21) or by means of the manual actuator (10), the coupling device (16) establishes a coupling connection between the wing locking device (12) and the tilt drive device (14).

[0121] The coupling device (16) has two coupling points (37, 38'), each formed by two interacting coupling elements (39, 40) and (41, 42). One coupling connection is established between the output element (15) and the adapter (17) at the coupling point (37). The second coupling connection is established between the output element (15) or the pin there and the guide (36) at the second coupling point (38'). The coupling device (16) further has a free passage (18) which decouples the wing (3) from the tilt drive device (14) for rotating the wing (3) about the rotation axis (6).

[0122] The said pin of the output element (15) on the driven link end (30) forms the first coupling element (39) at the first coupling point (37) and interacts with a coupling element (40) arranged on the bar (34) of the adapter (17). The second coupling element (40) is claw-like or mouth-like and has an outlet opening (43) between the claw or mouth arms on both sides. The outlet opening (43) points in the extension or tilting direction (19).

[0123] The coupling elements (39, 40) can engage with each other in a form-fitting manner, with the rounded pin being received in a corresponding internal recess of the jaw or claw arms, for example. This creates a form-fitting connection that is effective during a sliding and pivoting movement of the driven link arm (28). On the one hand, the adapter (17) and the associated wing lock (12) are moved back and forth in the locking direction (20), and on the other hand, the adapter (17) and the wing (3) are moved in the opening or tilting direction (19).

[0124] The coupling connection is at least in the Figure 5 shown operating position with the wing lock (12) open and before the start of the tilting movement of the wing (3). The coupling connection can also be used during the entire movement of the opening device (26) and its driven link (28) actuated by the drive (21) or the wing lock (12), as well as the Figure 3 shown retracted and locked rest position. Figures 8 and 9 show enlarged detailed images.

[0125] The coupling device (16) has a locking device (44) that secures the coupling connection and the driving function of the interacting coupling elements (39, 40). The locking device (44) has, for example, interlocking locking elements. These can be formed by the aforementioned positively adapted shapes of the coupling elements (39, 40). The locking device (44) can be activated by a mutual relative movement of the coupling elements (39, 40) along the locking direction (20) and deactivated by an actuating means (47) (not shown), e.g., a spring.

[0126] The second coupling point (38') is formed between the pin-shaped coupling element (39) and a fork-shaped coupling element (42), which acts as a receiver. The fork opening points in the locking direction (20) and toward the pin-shaped coupling element (39). The coupling element (42) is arranged on the guide (36) and on the side on which the adapter (17) is located. In the engaged and coupling position (38'), the lateral fork arms engage around the pin (39) and provide additional support against transverse forces in the extension or tilting direction (19). They extend slightly beyond the pin (39) and secure the coupling connection even in the event of positional tolerances and any incorrect movements in the locking direction (20).

[0127] The coupling element (40) on the adapter (17) can also engage with the coupling element (42). Figure 9a shortened front claw arm, allowing it to move over the fork. The coupling element (40) can also, for example, with its bulging outer side, engage positively in an undercut of the coupling element (42) above and at the rear end of the fork. The longer rear claw arm can strike the front of the fork. The coupling element (40) can have a dual function and can also serve as a driver-like coupling element (41).

[0128] Figures 3 to 9 illustrate the function of the tilt drive device (14) during motor-driven opening of the sash (3). Figure 3 and 8In the rest position shown, the link (28) is moved by the drive (21) in the direction of the arrow to the left along the locking direction (20). The coupling elements (39, 40) at the first coupling point (37) enter into a positive drag engagement. The adapter (17) is carried along by the link movement and initially moved into an intermediate position according to Figure 4 and then into a final position according to Figure 5 and 9 along the locking direction (20). This adapter movement drives the wing lock (12) along and opens it via the fastening means (35).

[0129] The further feed movement of the driven link (28) according to Figure 6 and the stop position in the handlebar slot (51) cause a subsequent rotational movement of the handlebar (28) and a related tilting of the wing (3) in the tilting direction (19) according to Figure 6 and 7. The downwardly extended pin of the output element (15) or coupling element (39) moves through the slot opening (50).

[0130] During the sliding movement of the driven link (28), the first coupling point (37) and the coupling elements (39, 40) are driven along, whereby the coupling connection between the extension device (26) and the guide (36) is closed at the second coupling point (38') before the start of the rotation and tilting movement. With the combined coupling points (37, 38'), a particularly high-strength coupling connection is formed between the extension device (26) and the sash (3) by means of the adapter (17), the guide (36), and the sash lock (12). Figure 7 an intermediate position is shown during the tilting movement of the wing (3) indicated here.

[0131] The sash (3) can also be tilted manually, whereby the coupling connection between the opening device (26) and the sash (3), in particular the sash lock (12), is closed and established. By manually operating the actuator (10), the sash lock (12) is moved in the locking direction (20) from the locked end position to the left, whereby the adapter (17) is carried along and, at the coupling point (37), with its coupling element (40), carries along the pin-shaped coupling element (39) and the driven link (28). In the manually unlocked end position, the sash (3) can be tilted, whereby the coupling connection between the opening device (26) and the sash (3), in particular the sash lock (12), is established and remains closed, and the pin-shaped coupling element (39) can be moved out through the slotted opening (50).The extension device (26) is carried by the closed coupling connection into the end position of the tilting position and the coupling connection remains closed even in this end position.

[0132] Closing of the manually or motor-tilted sash (3) can be performed either manually or by the tilt drive device (14). In both cases, the coupling connection between the opening device (26) and the sash (3), in particular the sash locking mechanism (12), remains intact.

[0133] When the wing (3) is closed by a motor, the driven link (28) is moved by the drive (21) in the opposite direction to the right along the guide slot (48), whereby the link gear (27) folds in and the wing (3) is returned to the position shown in Figure 5As the handlebar (28) continues to move into the end position, the adapter (17) is taken along over the coupling point (37) and pulled, whereby the wing lock (12) is closed and at the end the Figure 3 shown position is taken.

[0134] When the tilted wing is closed manually, the opening device (26) is also swung in by the manual force and into the position according to Figure 5 brought.

[0135] As soon as the Figure 5 shown position of the tilt drive (14), the manual closing of the wing lock (12) leads to a displacement of the driven link (28) and the adapter (17) into the position shown in Figure 3 shown locked end position.

[0136] The tilt drive device (14) has a separating means (25) that prevents an inhibiting drive connection between the drive (21) and the extension device (26). The separating means (25) is designed, for example, as an electromagnetic clutch (not shown). It can also be configured in another way.

[0137] Figures 10 to 13 illustrate the operating sequence when manually rotating the wing (3) around the rotation axis (6). The actuator (10) moves the wing lock (12) and the adapter (17) carried by it from the Figure 10 shown starting position into an intermediate position according to Figure 11in which a free passage (18) can be formed. The actuating means (47) is arranged between the coupling elements (39, 40), which, in this intermediate position, deactivates or opens the locking device (44) and removes the coupling elements (39, 40) from their mutual positive engagement. The details and function are explained in more detail below in connection with the second variant.

[0138] In the intermediate position, the manual actuator (10) and / or the wing lock (12) has a movement play which can be overcome by the actuating means (47) in order to release the positive engagement of the coupling elements (39, 40). In this intermediate position, the Figure 12 clarified clearance (18) when the wing (3) rotates, the coupling elements (39,40) are released from one another, whereby the pin (39) can emerge from the claw- or mouth-like coupling element (40) through the outlet opening (43). Figure 13shows the released position.

[0139] When the wing (3) is closed in the opposite direction, the coupling elements (39, 40) are brought into mutual engagement and into a coupling connection again, whereby they are subsequently moved into one of the end positions according to Figure 3 or 5 From the end position according to Figure 5 It is then immediately possible to tilt the wing (3) manually or by motor in the manner described above.

[0140] The extension device (26) or its driven link (28) is guided movably, in particular displaceably, along the locking direction (20) on the housing (14') of the tilt drive device (14). It is also pivotably guided in the extension or tilt direction (19) by means of the link (29). The guide is formed by the slots (48, 49) and the slot opening (50). The extension device (26) or its driven link (28) can follow the movements of the sash lock (12) due to the longitudinal mobility, whereby the said coupling connection exists. The slots (48, 49) can prevent any transverse movement or pivoting out of the extension device (26) or the link (28) over most of the displacement path. This concerns the displacement path of the sash locking device (12) and the opening device (26) between one locked end position via the unlocked intermediate position until just before the other unlocked end position for tilting the sash (3).

[0141] In the second variant of Figures 14 to 22 the deployment device (26) is again designed as a linkage (27), wherein according to Figure 21 and 22 The driven and angled link (28) is coupled to the leading link (29) by a pure rotary joint. The drive pin (24) is again moved back and forth along a guide slot (48) parallel to the locking direction (20) in the aforementioned manner as in the first variant.

[0142] The adapter (17), designed, for example, as an elongated strip (34), is connected to the wing lock (12) and the guide (36) in the manner described above. Furthermore, a separating means (25) of the type described above is also present. Figure 14 shows the locked end position of the sash lock (12) and the adapter (17), from which a linear displacement movement in the direction of the arrow to the left takes place to rotate or tilt the sash (3).

[0143] Differences exist in the design of the drive (21) and the coupling device (16). This has three coupling points (37, 38, 38'). One coupling point (37) between the opening device (26) and the sash (3) is formed by coupling the adapter (17) to the driven link (28). A coupling element (42) designed as a receiver is arranged at the free link end (30), which engages positively with a pin-like coupling element (41) designed as a driver at the free end of the strip (34) when the adapter is displaced. Figures 19 and 20 illustrate this.

[0144] A further coupling point (38') can be formed between the coupling element (42) on the link (28) and a coupling element (42') designed as a shell-shaped attachment on the guide (36). The outer curve of the coupling element (42) can engage positively with the coupling element (42') during a driven displacement movement.

[0145] In the second variant, the bar (34) of the adapter (17) can be driven independently by the drive (21) by means of a further drive means (23). In the first variant, the adapter (17) was entrained during an extension movement of the driven link (28) and driven together with it. In the second variant, a drive pin (24) is provided for the separate drive of the adapter (17), which can be moved in a guide slot parallel to the locking direction (20) by the drive (21). At the rear end of the bar (34) of the adapter (17), a mouth- or claw-like coupling element (40) with an outlet opening (43) is arranged, into which the coupling element (39) can insert in the extension or tilting direction (19). Figure 14 shows the closed and locked rest position, where Figure 15 the associated coupling point (38) and the mutual engagement of the coupling elements (39,40) are illustrated.

[0146] Figures 15 to 18also illustrate a suitable design of the locking device (44) and its locking elements (45, 46) as well as the actuating means (47). One locking element (45) is designed, for example, as an undercut on the rear side of the pin-like coupling element (39). The other positive locking element (46) is formed by projections on both sides of the arms of the other coupling element (40). In the case of a motorized drive movement of the drive pin (24) to the left or right, Figure 15 The locking device (44) is closed by positive engagement of the locking elements (45, 46) in the towing direction. The same applies to manual actuation and displacement of the adapter (17) by means of the wing lock (12) and the manual actuator (10).

[0147] In contrast to the first variant, the Figure 15In the end position shown at the coupling point (38), the adjusting means (47), e.g. designed as a spring, can be effective. It centers the pin-shaped coupling element (39) in the outlet opening (43) and releases the locking device (44). For this purpose, the driving pin (24) can be switched to a low-resistance position. The same can be done in the other end position of the pin-shaped coupling element (39) and the bar (34) of the adapter (17) according to Figure 17 happened. In Figure 16 a closed locking device (44) is shown in the said towing connection.

[0148] Figure 14 shows a locked end position of the adapter (17) and the associated wing lock (12) and the tilt drive device (14). From this position, the drive pin (24) can be removed from the Figure 15 shown locked end position to the position shown in Figure 17The adapter (17) moves according to Figures 19 and 20 the coupling elements (41,42) engage each other at the coupling point (37).

[0149] Figure 16 and 18 illustrate the unlocked end position, in which the locking device (44) is open. A further drive movement of the driven link (28) and its drive pin (24) causes a rotational movement of the link (28) and the associated tilting movement of the wing (3). Figure 22 shows the tilt position. The open locking device (44) allows the Figure 18 and 21 the adapter (17) with its coupling element (44) is released from the coupling element (39) and the coupling connection is opened at the coupling position (38).

[0150] The same happens when the adapter (17) engages and takes along the coupling elements (39,40) by manual actuation of the wing lock (12) and then the wing (3) is tilted.

[0151] The tilted wing (3) can be closed manually or by the drive (21) via the coupling point (37) and the coupling connection closed there. By retracting the link (28) or by actuating the wing lock (12) and taking along the adapter (17), the locked position is then restored according to Figure 14 taken.

[0152] The second variant also has a free passage (18). Here, the wing lock (12) is moved into an intermediate position, in which the driven bar (34) of the adapter (17) Figure 19Indicated intermediate position, in which the coupling elements (41, 42) are not yet engaged and the coupling connection at the coupling point (37) is open. At the third coupling point (38'), the coupling connection can be optionally open or closed.

[0153] In said intermediate position, the coupling elements (39, 40) at the second coupling point (38) are also in a position with the locking device (44) open, which is not shown in the drawings. When the sash (3) is rotated, the adapter-fixed coupling element (40) can be released from the drive-fixed coupling element (39). Upon subsequent closing of the sash (3), the coupling connection is closed again, whereby, as in the first variant, a subsequent manual or motor-driven tilting of the sash (3) or a closing of the sash lock (12) can then take place.

[0154] In the third variant of Figures 23 to 26The second coupling point (38) with the coupling elements (39, 40) and the driven adapter (17) is designed in a similar manner to the second variant. Differences lie in the different design of the extension device (26) and the associated drive (21).

[0155] In the third variant, the deployment device (26) is designed as a push chain (31) that is compression-resistant, in particular back-rigid. The push chain (31) has several articulated chain links (32) and an end piece (33) at the free chain end, which forms the output element (15) and a coupling element (42) at a coupling point (37) between the deployment device (26) and the leaf (3). The coupling element (42) forms a U-shaped receiver with a slotted base, into which a coupling element (41), designed as a driver, on the bar (34) of the adapter (17) can engage during the adapter's travel in the locking direction (20).

[0156] In the third variant, a coupling connection is also closed at the coupling point (37) for optional manual or motor-driven tilting of the sash (3).

[0157] A free passage (18) (not shown) for the free rotation of the wing (3) can also be formed. For this purpose, the adapter (17) is brought into an intermediate position by means of the wing lock (12), in which Figure 24 the coupling point (37) is still open and the coupling elements (41, 42) are not mutually engaged. On the other hand, the locking device (44) at the coupling point (38) can be released. Upon rotation of the leaf, the adapter (17) with its coupling element (40) can then be released from the coupling element (39).

[0158] Figures 27 to 51show a fourth variant of the tilt drive device (14). It is largely identical to the previous variants. It has a coupling device (16) with a coupling point (38') between the extension device (26) and the guide (36) and with a second coupling point (38) with coupling elements (39', 40') between the extension device (26) and the adapter (17). The drive (21) has a single drive means (22) which drives the adapter (17) and the extension device (26) together. Furthermore, a separating means (25) is provided. Differences exist, among other things, in the design of the extension device (26) and the adapter (17) as well as the guide (36).

[0159] Figure 27 shows an overview of a window (1) with a frame (2) and a tilt-and-turn sash (3), as well as a sash lock (12). This has a drive rod (11) with several locking elements (13). Figure 27illustrates different designs of the wing locking (12).

[0160] The adapter (17) has an elongated flat bar (34) and is fixed to the drive rod (11) with a fastening element (35). Figure 27 illustrates the adaptation of the adapter (17) to different positions and, if necessary, designs of the locking elements (13). It is connected to these elements by a form-fitting connection. Further details are in Figures 28 and 29 shown. Figure 27 shows only the strip-shaped adapter (17).

[0161] Figures 28 and 29 illustrate the adapter design. They also show a guide (36) that is permanently mounted or mounted on the sash (3) in the area of the drive rod (11). This guide is arranged separately and spaced apart from the adapter (17) in the locking direction (20) and has a different design and function.

[0162] The adapter (17) of the fourth variant differs from the previous variants with regard to its coupling element (40'). The coupling element (40') is designed as a pin projecting transversely from the drive rod (11). It interacts with a jaw- or claw-like coupling element (39') on the extension device (26), explained below. This creates a coupling connection at a coupling point (38) between the adapter (17) and the extension device (26). This design and arrangement of the coupling elements (39', 40') of the fourth variant are reversed compared to the first variant.

[0163] The adapter (17) can be made up of several parts. In the fourth variant, for example, it has several, e.g. two, flat adapter plates (53, 54) which lie one on top of the other with their broad sides facing one another and are jointly fixed to the drive rod (11) by the fastening means (35). The adapter plates (53, 54) each have one or more through openings (55), each of which is matched to and accommodates a locking element (13). The through openings are aligned one above the other in the assembled position of the adapter plates (53, 54). The through openings (55) each have a keyhole shape which varies between the upper and lower adapter plates (53, 54) with regard to an undercut (56) at the transition between the narrow and the wide keyhole area. The undercuts (56) allow the respectively accommodated locking element (13) to be positively engaged behind the shaft and fixed in the locking direction (20).

[0164] Furthermore, one or more elongated holes (57) and one or more fixing means (58) may be provided, which enable mutual adjustment or rotation of the superimposed adapter plates (53, 54) for positioning the undercuts (56). The resulting final position is fixed by the fixing means (35).

[0165] The wing-fixed guide (36) is in the fourth variant according to Figure 28 Designed as a slotted hollow guide profile (52) arranged and aligned along the locking direction (20). It has a base plate that can be mounted or is mounted on the leaf (3) above the drive rod (11) and has outwardly projecting guide walls that leave an axial guide slot between them.

[0166] In the fourth variant, the coupling point (38') is formed between an output element (15) at the end (30) of the extension device (26) and the guide (36). The output element (15) is designed as a mushroom-head-like bolt and can be inserted axially into the guide slot and the undercut interior of the hollow guide profile (52).

[0167] The bolt forms a coupling element (39) and the guide (36), in particular its guide slot, forms a coupling element (42"). The coupling elements (39, 42") can engage with each other in a form-fitting manner in the opening or tilting direction (19) and can thereby transmit the movements and forces during manual or motorized tilt opening and tilt closing of the sash (3).

[0168] Figure 30 illustrates the tilt drive device (14) in a perspective and laterally broken view, wherein the wing lock (12) is shown transparently. Figure 30shows an inverted arrangement looking at the underside of the wing lock (12) and the tilt drive device (14).

[0169] The open view of the housing (14') shows the drive (21) arranged therein with the individual drive means (22). In the inverted view, the opening device (26) is arranged on the housing (14').

[0170] In the fourth variant, the deployment device (26) has a pivoting lever (59). This lever is guided linearly along the locking direction (20) for most of the displacement path and pivotably at the end by means of a lever bearing (62) and a guide slot (65) on the housing (14').

[0171] The pivot lever (59) has an elongated shape and is moved by the drive (21). At each of its two spaced longitudinal ends, it has a coupling element (39, 39') for a coupling connection (38) with the adapter (17) and a coupling connection (38') with the wing-fixed guide (36). Further details of this design can be seen in the figures explained below.

[0172] Figure 30 shows the design of the drive means (22) with a motor (75) and a reduction gear connected upstream, as well as a drive means (76) driven by the motor (75) in a suitable manner, e.g., rotationally. The drive means (76) is connected to an output member (77). It is furthermore connected to a Figure 30 A drive pin (24) (not visible) is connected to the opening device (26) or the pivot lever (59). The output member (77) can be moved back and forth in the locking direction (20).

[0173] In the embodiment shown, the drive means (76) is designed as a threaded spindle, and the output member (77) as a spindle nut. Other designs are possible, e.g., as a belt drive or the like. As in the first variants, a controllable separating means (25) can prevent or remove the inhibiting drive connection as needed for manual actuation of the leaf lock (12) and the leaf (3). The separating means (25) is designed as a controllable coupling (25'), which is explained in more detail below.

[0174] Figures 31 to 33 show a movement sequence during a manual or motorized movement of the sash lock (12) for tilt-opening a closed sash (3). The sliding movement along the locking direction (20) is directed from right to left in the drawings.

[0175] Figure 31illustrates the locked end position of the sash lock (12), with the sash (3) assuming a closed or rest position. In this end position, a coupling connection exists at the coupling point (38) between the opening device (26) and the adapter (17) through mutual engagement of the coupling elements (39', 40'). The output element (15) at the end (30) of the pivot lever (59) is axially spaced from the guide (36) or the guide profile (52) and is not engaged with it. The coupling point (38') is only closed later.

[0176] Figure 32 illustrates an intermediate position with the free passage (18), which allows the sash (3) to be rotated. The sash lock (12) is manually or by the tilt drive device (14) in the locking direction (20) according to the arrow of Figure 32linearly shifted to the left. In this intermediate position, the output element (15) is disengaged from the guide (36), whereby the coupling connection (38') is not yet closed. The output member (77) has moved along the locking direction (20) together with the engaged pivot lever (59) and is guided straight by the slotted guide (65) and cannot pivot sideways.

[0177] The coupling connection at the coupling point (38) between the deployment device (26) and the adapter (17) or between the coupling elements (39', 40') is closed uniaxially in the locking direction (20), whereby the mouth-like coupling element (39') points with its outlet opening (43) in the deployment or tilting direction (19). The sash (3) can be rotated and opened in the intermediate position, whereby the pin or coupling element (40') on the adapter (17) is moved out of the outlet opening (43) and the coupling connection is opened. Conversely, it can be re-engaged when the sash (3) is rotated back and closed, and the coupling connection can be closed again.

[0178] Figure 33shows the other end position of the sash lock (12), which enables tilting of the sash (3) and sideways pivoting of the opening device (26) or the pivoting lever (59). In this end position, the output means (15) or coupling element (39) and the wing-fixed guide (36) or the coupling element (42") are in positive engagement, wherein the coupling connection at the coupling point (38') is closed. Before the tilting movement of the wing (3) begins, the other coupling connection at the coupling point (38) between the extension device (26) and the adapter (17) or between the coupling elements (39', 40') is also closed uniaxially in the locking direction (20). The mouth-like coupling element (39') points with its outlet opening (43) in the tilting direction (19). During the subsequent tilting movement, the coupling connection at the coupling point (38) is opened.

[0179] To close and lock the sash (3) the movement sequence of Figures 31 to 33 in the opposite direction.

[0180] Figures 34 and 35 show a first tilt position of the sash (3) and the tilt drive device (14) in a perspective top view, cut open from the side, and in a perspective bottom view. In this tilt position, the coupling connection between the opening device (26) or the pivot lever (59) and the adapter (17) is opened or released at the coupling point (38). The coupling elements (39', 40') are moved apart, so that the pivot lever (59) and the jaw-like coupling element (40') can pivot unhindered.

[0181] The other coupling connection at the coupling point (38') between the opening device (26) and the wing-fixed guide (36) is closed, so that the drive force of the tilt drive device (14) tilts the wing (3) or the tilt drive device (14) is driven along when the wing (3) is tilted manually.

[0182] Figures 36 and 37show a further tilted position of the sash (3) and the tilt drive device (14) in top view and bottom view. During the tilting movement, the pivot lever (59) continues to rotate, whereby at the coupling point (38') the output element (15) on the sash-fixed guide (36) is moved in the locking direction (20) into the position shown in Figure 36 shown end position. The link guide (65) guides the rotating or pivoting movement of the pivot lever (59).

[0183] Figures 38 and 39show the pivot lever (59) in various views. The pivot lever (59) has an angled lever shape with lever arms (60, 61) of different lengths aligned transversely to one another, as well as a lever bearing (62) arranged at the transition point between the longer lever arm (60) and the shorter lever arm (61). The lever arms (60, 61) are aligned, for example, at right angles to one another. The lever bearing (62) interacts with a slotted guide (65) on the housing (14'), explained below.

[0184] The long lever arm (60) has a partially curved and partially straight orientation. The curved lever section adjoins the transition point between the lever arms (60, 61). The straight lever section is arranged downstream and extends to the free end (30) of the pivot lever (59) or lever arm (60). In the pivoted-in position of the pivot lever (59), the straight lever section is aligned along the locking direction (20).

[0185] A guide slot (68) is arranged in the curved lever section, which has a curved slot section (69) and a straight slot section (70) adjoining it at the end. The curved slot section (69) can start from the said transition point. The straight slot section (70) is aligned parallel to the straight lever section and, in the said closed position, parallel to the locking direction (20). The straight slot section (70) merges into the curved slot section (69) with a rounded portion at its end region facing the free end (30). At the other end, the straight slot region (70) has a step-like and preferably transversely directed shoulder (71) at the transition point to the curved slot section (69).

[0186] The guide slot (68) serves to accommodate the drive pin (24) on the drive means (22). The driven linear movement of the drive pin (24) is converted into a rotary and pivoting movement of the pivot arm (59) by the curved guide slot (68). The shoulder (71) serves to transmit the power of the drive (21) to the pivot lever (59) and acts as a drag stop for the drive pin (24). This will be described below. Figures 42 to 51 explained.

[0187] The short lever arm (61) forms the claw- or mouth-like coupling element (39') and has an outlet opening (43) at its free end, which serves to form the free passage (18). It also enables opening of the coupling connection at the coupling point (38) and tilting of the wing (3).

[0188] A locking device (44) can be arranged on the coupling element (39') and on the outlet opening (43). In the fourth variant, this is formed by a spring clip (90) having a clip opening (91) pointing in the extension or tilting direction (19). The spring clip (90) can be held on a round bolt at the transition point between the lever arms (60, 61) for limited pivotal movement and can extend through openings in an inclined transition section of the short lever arm (61). Figures 38 and 39 show the lever arm (59) without the spring clip (90). The assembled arrangement is shown in Figure 35 and 37 visible.

[0189] The clamp opening (91) may have an undercut shape. The clamp arms are designed accordingly. Figure 40shows this design. The undercut clamp opening (91) is located at the outlet opening (43) and resiliently accommodates the pin-like coupling element (40') on the adapter (17).

[0190] The claw-like coupling element (39') has undercut side walls, which also act as a locking mechanism during linear travel. This effect is lost when the pivot lever (59) rotates.

[0191] The locking device (44) or the spring clip (90) and the undercut coupling element (39') prevent an undesired pin exit and an undesired sash opening during the sliding movement of the drive rod (11) and when the locking elements (13) are released or when the sash lock (12) is opened.

[0192] The lever bearing (62) on the pivot lever (59) is formed, for example, by two separate and spaced-apart bearing parts (63, 64), which in the illustrated embodiment are designed as round bearing pins projecting transversely from the sash surface. When the pivot lever (59) is closed or pivoted in, the bearing pins (63, 64) are arranged one behind the other at a distance along the locking direction (20).

[0193] The lever bearing (62) acts with a Figure 40The latter comprises a guide plate arranged on the upper side of the housing and projecting transversely, in which a straight guide part (66) and a curved guide part (67) are arranged. The guide parts (66, 67) engage with the bearing parts (63, 64). In the embodiment shown, the guide parts (66, 67) are designed as guide slots into which the bearing bolts (63, 64) engage. The arrangement with the allocation of slots and bolts can alternatively be reversed. The interaction of the lever bearing (62) and the guide plate (65) is explained below. Figure 40 The top side of the housing (14') shown is in an installation position according to Figure 1 at the window (1) directed downwards.

[0194] Figure 40 also illustrates the design and arrangement of a deflection aid (72), which supports the pivoting movement of the pivot lever (59) during tilting. Figure 40also shows the arrangement of the driven drive pin (24) on the housing (14'). The drive pin (24) protrudes from the driven element (77) through an axial longitudinal slot on the upper side of the housing shown. It can thus be connected to the Figure 40 not shown pivot lever (59) and its guide slot (68) engage.

[0195] The deflection aid (72) consists of a steering lug (73) arranged on the pivot lever (59), in particular on the long lever arm (60), and protruding transversely from its main plane. This lug is directed towards the upper side of the housing shown. One or two inclined steering stops (74) are arranged on said upper side of the housing, which interact with the steering lug (73). When the unlocked end position of the sash lock (12) and the adapter (17) is reached at the end of the linear displacement movement of the opening device (26) or the pivot lever (59), the steering lug (73) runs against the associated inclined steering stop (74) and is displaced to the side during a continued displacement movement. This assists the pivoting out of the pivot lever (59) and the tilting of the sash (3) during a motor-driven tilting movement. The steering lug is arranged on the long side of the long lever arm (60) facing the short lever arm (61).Depending on the window's specifications, the tilt drive mechanism (14) can have a correspondingly curved pivot lever (59) that swings to the left or right. The steering stops (74) are provided in duplicate for left and right swings.

[0196] Figure 30 and 41 illustrate the design of the drive means (22) and the coupling (25'). The output member (77), designed, for example, as a spindle nut, is arranged on the drive means (76), designed, for example, as an axial threaded spindle. The spindle nut (77) has a nut housing (80) that surrounds the threaded spindle (77) and carries a projecting guide web on the upper side and, adjacent to it, the drive pin (24). Both extend through the aforementioned longitudinal slot on the upper side of the housing and are guided axially there.

[0197] The nut housing (80) is guided laterally within the housing (14') by guide means (81, 82) extending, for example, on both sides and along the locking direction (20). The guide means (81, 82) are formed, for example, by guide slots (82) in the lateral housing wall and engaging elongated guide webs on the nut housing (80).

[0198] The spindle nut (77) has one or more, in particular two, nut parts (78, 79), e.g., in the form of threaded jaws. These can be brought into and out of engagement with the threaded spindle (76) in a controlled manner by the coupling (25'). This allows the drive connection between the extension device (26) and the drive (21) to be opened and closed as required.

[0199] An actuating device (85) is provided for the actuation of the clutch (25'). Figure 30a controllable actuator (86), e.g., an electric motor, and a rotatingly driven actuating rod (87) extending parallel to and in the locking direction (20) along the threaded spindle (76). An actuating thread (88) is arranged on the actuating rod (87) in a rotationally locked and longitudinally movable manner. This actuating thread is connected to the coupling (25') and can move along the threaded spindle (76) together with the spindle nut (77). The actuating rod (87) and the actuating thread (88) have, e.g., a prismatic outer and inner contour.

[0200] The coupling (25') has coupling means (83, 84) which cooperate with the nut parts (78, 79) for their movement and adjustment and which are actuated by the adjusting device (85) by means of the adjusting thread (88). One coupling means (83) is designed, for example, as a coupling housing which is arranged and received in the nut housing (80) and engages with the adjusting thread (88). The coupling housing (83) is mounted so as to be movable in the spindle direction and has thread means which engage with the adjusting thread (88). A rotary movement of the adjusting rod (87) can be converted into a longitudinal movement of the coupling housing (83). The adjusting thread (88) is designed, for example, as a worm whose threads are in threaded engagement with guide slots on the bottom of the coupling housing (83).

[0201] The coupling housing (83) is connected to the nut parts (78, 79) via a guide means (84) which converts a displacement movement of the coupling housing (83) directed along the threaded spindle (76) into an approach movement of the nut parts (78, 79) to the threaded spindle (76). For example, the two jaw-like nut parts (78, 79) are arranged above and below the threaded spindle (76) and are moved towards the threaded spindle (76) by the guide means (84) and engaged with its thread or released from the threaded spindle (76) and from the threaded engagement. The guide means (84) is designed, for example, as a pin guide in which transversely projecting pins on the nut parts (78, 79) engage and are guided in inclined guide slots on the coupling housing (83).

[0202] The coupling (25') is actuated via the actuating device (85) and the control of the actuator (86). The control can be such that the coupling (25') is automatically closed when the drive (21) of the tilt drive device (14) is actuated and automatically opened when the drive (21) is at a standstill. This means that, when the drive (21) is stationary, the actuator (10) can be manually operated at any time, and the sash (3) can be manually rotated or tilted as desired. During manual operation, the sash lock (12) and the adapter (17) move the opening device (26) in a sliding movement along the locking direction (12). When the coupling (25') and the drive connection are open, the spindle nut (77) can be moved along with the adapter (17) by means of the coupling connection between the adapter (17) and the opening device (26) and by means of its connection to the drive pin (24).This, in turn, takes the adjusting thread (88) with it and moves it along the adjusting rod (87). The open nut parts (78, 79) offer no significant resistance to this displacement movement. In any position along this displacement path, the drive (21) can be reactivated and the clutch (25') can be closed.

[0203] This design and function of the clutch (25') can also be used in the other variants. Furthermore, a separating means (25) designed in a different manner can also have a corresponding function and control.

[0204] Figures 42 to 51 show a movement sequence of the tilt drive device (14) during manual tilting of a sash (3) from the locked rest or closed position of the sash (3). A top view and a bottom view are shown in pairs.

[0205] Figures 42 and 43The top and bottom views illustrate the locked end position with a closed leaf (3) in the rest position. The pivot lever (59) is pivoted in and aligned with its straight arm section along the locking direction (20). The bearing pins (63, 64) are located at one end of the straight slot (66). They form a straight guide that prevents the pivot lever (59) from pivoting sideways. The coupling connection at the coupling point (38) is closed.

[0206] During a sliding movement of the sash lock (12), the opening device (26) or the pivot lever (59) is driven via the adapter (17) by means of the coupling point (38). The other coupling connection at the coupling point (38') is open. During the sliding movement, the opening device (26) or the pivot lever (59) drives the output element (77) via the drive pin (24). The drive pin (24) is located at the end of the straight slot section (70) facing the free lever end (30).

[0207] Figures 44 and 45illustrate the unlocked intermediate position with the sash lock (12) open and the free movement (18), as well as the option for manually rotating and opening the sash (3). When the sash rotates, the pin (40') connected to the adapter (17) is moved out of the outlet opening (43) and the clamp opening (91), as well as out of the mouth-like coupling element (39'), in the opening or tilting direction (19). In the intermediate position, the lever bearing (62) on the slotted guide (65) is still guided in a straight line, preventing the pivoting lever (59) from pivoting out.

[0208] Figures 46 and 47illustrate the other end position of the sliding movement of the sash lock (12) and the adapter (17), in which tilting of the sash (3) is possible. The bearing pins (63, 64) are located at the other end of the straight link slot (66), whereby one bearing pin (64) is positioned at the opening point of the curved link slot (67) and can enter here when the pivot lever (59) pivots out. During the sliding movement, the coupling connection at the coupling point (38) is closed. It can be opened when the sash (3) is tilted. The other coupling connection at the coupling point (38') is closed, so that when the sash (3) tilts, the opening device (26) or the pivot lever (59) is driven along and executes a pivoting movement.

[0209] Figures 48 and 49illustrate such a sash tilting into an intermediate position and a corresponding pivoting position of the opening device (26). The rotating pivot lever (59) moves the drive pin (24) and the output element (77) linearly in the sliding direction or in the locking direction (20). Figure 49 shows the rotational position of the lever bearing (62) in the guide rail (65). The bearing pin (64) is inserted into the curved guide rail slot (67) and is in an intermediate position.

[0210] Figures 50 and 51illustrate a tilted end position of the wing (3) with the pivot lever (59) pivoted out to its maximum. The drive pin (24) is located at the end of the guide slot (68). The bearing pin (64) is fully inserted into the curved slot (67). The other bearing pin (63) is attached to the end of the straight slot (66) and can rotate. Such a rotation possibility is also previously shown in the partially pivoted position of Figures 48 and 49 possible. The distance between the bearing pins (63, 64) is adjusted to the radius of the concentrically curved slotted guide (67).

[0211] When the wing (3) is tilted by motor from the locked rest or closed position, the Figures 42 to 51The movement sequence of the tilt drive device (14) shown is essentially the same, with the difference that during motor-driven tilting the driving pin (24) pushes the opening device (26) or the pivoting lever (59) in the direction of displacement. The drive (21) moves the driving pin (24) a short distance along the straight slot section (70), whereby the opening device (26) and the adapter (17) are not yet moved along with it. Driving only occurs when the driving pin (24) rests on the shoulder (71) of the straight slot section (70). In the further movement sequence the lever bearing (62) and the slotted guide (65) ensure that the opening device (26) is guided straight and prevent it from pivoting out to the side. This is also the case in the intermediate position for the rotation of the sash (3) and the formation of the free passage (18).

[0212] After the unlocked end position of the sash lock (12) and the adapter (17) has been reached, the further linear displacement movement of the driven driving pin (24) causes the pivoting lever (59) to pivot. The thrust exerted by the driving pin (24) generates a pivoting torque directed around the lever bearing (62). The deflection aid (72) also participates. The driving pin (24) slides along the shoulder (71) and enters the curved slot section (69), along which it travels during the further displacement movement and causes the pivoting lever (59) to rotate. The sequence of movements at the lever bearing (62) and the slotted guide (65) corresponds to the manual sash movement.

[0213] To manually or motor-drivenly close the tilted sash (5), the illustrated movement sequence is reversed. When the sash (3) is manually rotated or tilted, the inhibiting drive connection is removed or at least reduced by the separating means (25) or the coupling (25'). When the sash (3) is tilted open or closed by motor, the drive connection is closed.

[0214] The tilt drive device (14) can have a detection device (89) with which relevant operating parameters of the tilt drive device (14) can be detected and used for different purposes. Such a parameter can be, for example, a position and / or a path of the sash (3) and / or the tilt drive device (14) and / or the sash lock (12). A position and / or a path of the sash (3) can be detected directly or indirectly. Indirect detection is possible, for example, via the tilt drive device (14). The coupling connection between the extension device (26) and the adapter (17) or the sash lock (12) can be used here. The detection device (89) can be arranged in particular on the tilt drive device (14), preferably on the housing (14'). It can also be used with the other variants of the tilt drive device (14).

[0215] Figure 40shows a possible arrangement on the housing (14'). The detection device (89) can have one or more suitable sensors for detecting a position of the drive (21) or a drive means (22, 23). In particular, the position and / or travel of an output element (77), in particular a spindle nut, can be detected. For this purpose, the detection device (89) can, for example, have a travel or position sensor on the output element (77) and a position or travel sensor, e.g. in the form of a strip, on the housing (14'), in particular on the guide means (82).

[0216] The detection device (89) can be signal-connected to a control system (not shown) of the tilt drive device (14). The power supply can also be provided via this system. Furthermore, a signal connection can be made to a higher-level control system, e.g. in building technology. By means of such indirect monitoring of the sash position and / or sash movement, the sash (3) can be controlled for ventilation, smoke extraction or other purposes. In the case of a burglar detection or alarm system, an unauthorized sash movement indicating an attempted break-in can be detected. Furthermore, to protect against heat loss or environmental influences such as rain, snow or the like, all detected tilted windows (1) can be automatically closed by such a higher-level control system.

[0217] Figures 52 to 60illustrate a fifth variant of the tilt drive device (14). This also largely corresponds to the previous variants, especially the fourth variant.

[0218] The tilt drive device (14) has a coupling device (16) with a coupling point (38') between the extension device (26) and the leaf-fixed guide (36) and with a second coupling point (38) between the extension device (26) and the adapter (17). The drive (21) has a single drive means (22) with a motor (75) which jointly drives the adapter (17) and the extension device (26). Furthermore, a separating means (25) or a coupling (25') is present. Differences exist, among other things, in the design of the extension device (26) and the adapter (17), as well as the coupling point (38') and the locking device (44).

[0219] Figure 52 and 53show the tilt drive device (14) in perspective view with different viewing angles, wherein in Figure 53 a part of the housing (14') is omitted.

[0220] The drive (21) with the drive means (22), the spindle (76) and the spindle nut (77) with the coupling (25') as well as the adjusting device (85) with the actuator (86) and the adjusting rod (87) can be designed in the same way as in the fourth variant.

[0221] The adapter (17) has a flat, elongated strip (34) and is attached to the drive rod (11) by a fastener (35). Furthermore, a guide (36) for the adapter (17) may be provided, which has an elongated hole on the adapter (17) and on the drive rod (11), as well as a screw inserted through it and connected to the leaf (3).

[0222] How Figures 54 and 55in a side view and a bottom view, in the fifth variant a coupling point (38) is also formed between the opening device (26) and the adapter (17), whereby here the clearance (18) for the rotary movement of the wing (3) about the bearing axis (6) is also created.

[0223] In contrast to the fourth variant, a pin-shaped coupling element (39) is arranged on the deployment device (26) and engages positively with a jaw-like coupling element (40) on the adapter (17). The jaw-like coupling element (40) has an outlet opening (43) pointing in the deployment or tilting direction (19), through which the coupling element (39) can exit to form the free passage (18). This design of the coupling point (38) is functionally similar to the first variant.

[0224] The side walls of the mouth-like or U-shaped coupling element (40) extend straight in the extension or tilting direction (19). In contrast to the fourth variant, undercuts and their locking effect are eliminated. The locking device (44) is designed differently in the fifth variant and is described below.

[0225] As in the fourth variant, the deployment device (26) comprises an elongated, curved pivot lever (59) with a long, slender lever arm (60). Instead of the short, transversely directed lever arm (61), the pivot lever (59) has a widened rear portion on the lever arm (60). At the end of this portion, the aforementioned pin-shaped coupling element (39) for the coupling point (38) to the adapter (17) is arranged.

[0226] The second coupling point (38') is formed, as in the fourth variant, by a pin-shaped output element (15) or coupling element (39) at the other front end (30) of the lever arm (60) and a slot-like coupling element (42") on the further guide (36) fixed to the frame. The drive (21) moves the pivot lever (59) and thus both pin-like coupling elements (39) together.

[0227] The pivot lever (59) of the fifth variant has a lever bearing (62) as in the fourth variant, which has a link guide (65) on the underside of the housing (14') with a straight link slot (66) and a curved link slot (67), wherein bearing bolts (63, 64) mounted on the pivot lever (59) engage here.

[0228] On the other hand, as in the fourth variant, the pivot lever (59) has a guide slot (68) with a curved slot section (69) and a straight slot section (70) along with a shoulder (71) for the engagement of the drive element, in particular the drive pin (24), of the drive (21). The drive pin (24) is attached to the underside of the spindle nut (77), which in turn is guided by an elongated strip in a longitudinal slot on the bottom of the housing (14') in the locking direction (20).

[0229] In the fifth variant, a deflection aid (72) is also provided for the pivot lever (59). It consists of stationary steering stops (74) on the underside of the housing (14') and steering lugs (73) on the pivot lever (59), particularly on the lever arm (60). The steering lugs (73) are designed as bevels on the longitudinal edges of the lever arm (60).

[0230] How Figure 57As illustrated in a perspective view from below, the function of the tilt drive device (14) and in particular of the opening device (26) is the same as in the fourth variant. The pivot lever (59) is moved by the drive pin (24) in the locking direction (20) and pivoted by means of the slotted guide (65) at the end of the linear movement to tilt open the sash (3).

[0231] In the fifth variant, the locking device (44) is designed differently than in the previously described embodiments. The locking device (44) is also no longer connected to coupling elements and a coupling point. In the fifth variant, the locking device (44) is formed by a stop (92) on the adapter (17) and an extendable stop (93) on the housing (14').

[0232] The stop (92) is designed, for example, as a raised stop bar on one longitudinal edge of the adapter (17) located in the tilting direction (19). The stop (92) is moved along during the linear movements of the adapter (17) or the wing lock (12) in the locking direction (20).

[0233] The stop (93) can be extended from the housing (14') toward the adapter (17) and retracted again. In the extended position, it can overlap the stop bar (92) and strike upon a sash movement in the tilt or opening direction (19). As in the previous embodiments, the stops (92, 93) form cooperating locking elements of the locking device (44).

[0234] In the fifth variant, the actuating means (47) of the locking device (44) is formed by a drive means (94) for the extendable stop (93), which is connected to the actuating device (85). The drive means (94) is formed by a gear transmission driven by the rotating actuating rod (87), wherein this rotary movement is transmitted via a Figure 53 visible eccentric is converted into a linear displacement movement of the extendable stop (93). Depending on the direction of rotation of the adjusting rod (87), the stop (93) is extended or retracted.

[0235] The locking device (44) can be activated during a motorized adjustment of the wing locking mechanism (12) and deactivated during its manual operation. It can be activated and deactivated when the drive (21) and / or the separating means (25) of the tilt drive device (14) are activated.

[0236] When the drive (21) is activated for a motorized adjustment of the extension device (26), the release means (25) or the controllable coupling (25') is actuated by the actuating device (85), for example, and the aforementioned inhibiting drive connection is established. The locking device (44) is also actuated, and the stop (93) is extended. When the inhibiting drive connection is released again by actuating the release means (25) or the coupling (25'), the stop (93) is retracted.

[0237] Figures 58 to 60 illustrate the function of the locking device (44). Figure 58 shows a position of the tilt drive device (14) in the locked closed position of the wing (3). This position is also shown in Figure 54shown. In the locked closed position, the sash (3) is held to the frame (2) by the locking elements (13). In this closed position, the inhibiting drive connection is released or opened by corresponding actuation of the separating means (25) or the coupling (25'). In the fifth variant, the spindle nut (77) with its nut parts (78, 79) is not engaged with the spindle (76). The opening of the coupling (25') and the deactivation of the locking device (44) are effected jointly by the adjusting device (85).

[0238] Figure 59 shows the operating position when the drive (21) and the separating means (25) or the coupling (25') are activated. In this case, the actuating device (85) closes the drive connection between the spindle nut (77) and the spindle (76), while the locking device (44) is actuated and the stop (93) is extended.

[0239] If subsequently according to Figure 60 the drive (21) comes into operation and the opening device (26) as well as the adapter (17) carried along via the coupling point (38) are in Figure 60 If the sash (3) is moved to the right, the aforementioned intermediate position is overrun for a possible rotary opening of the sash (3). The stops (92, 93) are positioned relative to one another in such a way that, during this linear movement, the two stops (92, 93) in the tilt or extension direction (19) overlap in the area of the intermediate position. If an external force, such as wind pressure or the like, acts on the sash (3) in this position, the overlap and stop function prevent the sash (3) from rotating about the bearing axis (6).

[0240] As soon as the aforementioned intermediate position is passed and the other end position of the sash locking mechanism for motorized tilting of the sash (3) is reached, the stops (92, 93) no longer overlap. At the same time, however, the other coupling point (38') between the opening mechanism (26) and the sash-fixed guide (36) is closed, so that even in this position, the sash (3) cannot perform any unwanted movement.

[0241] Modifications to the embodiments shown and described are possible in various ways. In particular, features of the described embodiments can be combined with one another and, if necessary, even interchanged. The assignment of the pin- and claw-like coupling elements (39, 40) as well as the coupling elements (41, 42, 42') designed as drivers and receivers can be interchanged compared to the variants shown. Furthermore, the drive technology can also be modified and adapted. LIST OF REFERENCE SYMBOLS
