The invention relates to an opening device for a turn-tilt wing of a window or a door with a locking device and a base frame attached to the base part according to the preamble of claim 1.

Is known from the EP 2 072 734 A1 an opening device for a tilt-wing or tilt-turn wing of a window or a door, with a locking device and a base frame fixed to the base part, on which an actuatable by means of a motor drive Ausstellschere is mounted, which has a connecting member to the wing, said Connecting member is a drive rod connecting element, wherein by means of the motor drive device, the locking device can be brought into a locking and unlocking, wherein the drive rod connecting element in itself in the closed position Ausstellschere and befindlichem in the locking position locking device with an espagnolette manually and manually is separable from this.

An opening device with a locking device of this type is characterized by the DE 10 157 094 C1 already known. The known Ausstellvorrichtung has a locking device and a frame attached to the base part, on which an actuatable by means of a motor drive Ausstellschere is mounted, which has a connecting member to the window sash, wherein the connecting member is an espagnolette element connecting element. By means of the motor drive device, the locking device can be brought into a locking and unlocking position, wherein the drive rod element connecting element is automatically connectable and automatically separable from this in the closed position Ausstellschere and locking device located in the locking device with an espagnolette element. The separating and connecting the Ausstellschere to the espagnolette locking pin the locking device via a arranged on the Ausstellschere link, which has a catch hook, which automatically assumes an open position by means of the motor drive device and allows manual actuation of the locking or unlocking mechanism of a turn-tilt wing.

Accordingly, a manual actuation by means of an actuating handle of the prior art can be achieved only by an automated separation by a Ausstellschere located in the closed position by means of the drive motor, a drive rod locking pin of the locking device from an unlocked position into a locking position or vice versa, and is movable a catch hook automatically assumes an open position. In case of failure of the drive motor opening the wing is not feasible or difficult to achieve with the resistance of the drive device.

By using a control scissors, which is based on a toggle lever principle prevail when closing due to the low installation dimensions unfavorable geometric conditions in the control scissors, which require very high driving forces. Due to the concealed installation is not visible to the user that a motor drive is installed. When trying to manually operate the power window in locking end position, the window may not be opened or the motor drive is damaged, since an automatic unlocking the Ausstellschere to motor drive could not be performed.

The approach of a motor-controlled position in a tilting position is known from the prior art. The prior art, however, does not disclose a turn-tilt wing deployment device of a window or door with a hybrid drive that allows the motorized start-up of a locking device into the rotational position with automated disconnection of the motor from the locking device, and manual opening the rotational position allowed. The same functionality is also possible for the tilted position. In addition, it is possible to switch from automatic opening and closing to manual operation.

The invention has for its object to provide an opening device for a turn-tilt wing of a window or a door of the type mentioned, which allows a motorized and manual tilting, allows a motor and manual start in the manually operable rotational or tilting position, manufacturing technology is simple and inexpensive, can be mounted and adjusted in a simple, fast, safe and precise manner and which avoids the aforementioned disadvantages.

The solution of the problem is achieved by the means of the characterizing part of claim 1.

By manually operating by means of an actuating handle of the locking device, the locking device can be manually separated from a tilting device for a turn-tilt wing of a window or a door and thus from a base frame fixed to the base part with a motor drive device.

Also, a motor starting by the drive device in a subsequently manually operated rotary position or manually open tilt position with automatic opening and closing or separating and coupling a drive rod connecting element without additional component complexity is possible.

For this purpose, in an advantageous manner, the opening device has a locking device and a base part attached to the frame, on which a Ausstellschere operable by means of the motor drive device is mounted with a holding arm, which has a connecting member to the wing. The connecting member is a driving rod connecting element. By means of the motor drive device, the locking device can be brought into a locking and unlocking position, wherein the drive rod connecting element is arranged at a free end of the support arm, consists of a recess arranged on the support arm and a hook which can be acted upon by a spring element spring force is. The espagnolette connecting element is located in the closed position Ausstellschere and located in the locking position locking device of a driving rod as having element Espagnolette locking pin, during motorized adjustment in the direction of rotation position with striking the drive rod locking pin to an inner edge of the hook, automatically separable. With swung open hook, the Ausstellschere takes the closed position motor and thus gives the rotational position of the espagnolette locking pin free. The drive rod locking pin of the locking device is in a freely operable field according to this embodiment in the rotational function position, so that detached from the drive device of the wing can be manually transferred to an open rotational position. With renewed start the Ausstellschere from the closed position with the hook open in the direction of rotational position arranged espagnolette locking pin and engagement of the espagnolette locking pin in the recess of the support arm in the rotational position, so automatically connecting the hook with the espagnolette locking pin by loosening of the spring element is introduced from a permanently tensioned position out with a arranged on a base part spring tensioner in a tensioned position with the hook, which causes a connection by pivoting the spring force acting on the hook. With motor retraction from the rotational position in the direction of the closed position Ausstellschere and in the direction of locking locking device of the espagnolette locking pin, the espagnolette locking pin is held adjacent to an inner edge of the hook, wherein the spring element relaxes the hook and enters a permanently tensioned position with the spring compressor ,

To ensure the automatic connection of the hook with the espagnolette locking pin is automatically tensioned by the leg spring with motorized adjustment of Ausstellschere in the rotational position of the hook, wherein a web arranged on the hook forms an end stop for the second free end of the leg spring.

Also for manual actuation, the display scissors arranged manually by the locking device releasable Ausstellschere on the wing coupling link, which is a connecting rod connecting element and on the one hand by means of the motor drive device, the locking device is transferred to a locking and unlocking position and on the other hand, the manual separation in the closed position Ausstellschere and in itself in locking position located locking device with a drive rod element allows.

An advantageous further development provides that the support arm of Ausstellschere is longitudinally displaceable by means of a longitudinal slot with a bearing pin arranged on the base and rotatably mounted about a Lagerbolzenachse and a back-rigid chain which is connected to one end on the support arm and drivingly connected to the other end with the motor drive device is.

It is further provided that the support arm and the chain when opening by means of the motor drive device with a first part of the hub in the longitudinal direction of the base part are displaced and with a second part of the stroke, the chain at a guided exit from the base part in a free field in a transferred almost right angle to this base part, whereby the holding arm is pivoted automatically. With the kinematic course of the musculoskeletal system when adjusting the Ausstellvorrichtung a small size of the Ausstellvorrichtung is required so that the assembly of the Ausstellvorrichtung can be mounted in the frame in almost all common window frames systems. To achieve a high drive speed, the power-limited due to small size motor drive device is used evenly and optimally. Therefore, it is advantageous to provide a pivotable about a pivot point on the housing of the base member retaining arm, which is controlled approximately centrally of the chain. The resulting stroke magnification of the support arm and high chain force causes the translation of the Verrieglungsvorrichtung optimal translation for tilting the wing.

In an advantageous embodiment, the drive rod connecting element is arranged at the free end of the support arm and consists of a on the front side of the support arm having recess and a hook, which is subjected to a force by a spring element. Further, the drive rod connecting element is in engagement with the drive rod locking pin having the locking device as locking element in the locking position. The drive rod locking pin and the drive rod connecting element are the interface to the motor drive device of the opening device and the locking device.

A secure locking and a secure separation and connecting the release device to the locking device are also made possible when the drive rod locking pin is formed as a mushroom pin. The mushroom pin execution proves to be advantageous in that the connection of the drive rod locking pin is secured to the drive rod connecting element with a possible increase in the distance between the wing and the frame within the folding surfaces against accidental disengagement.

It is further contemplated that the Ausstellvorrichtung and the locking device are held in a secure coupling for the motor tilt position. For this purpose, the hook, with the arranged in the recess of the support arm drive rod locking pin incessantly positively connected.

An embodiment of the invention results from the fact that for manual separation of the secured position, for example, after motor actuation of the tilting position of the opening device, the drive rod connecting element with reaching the closed position located Ausstellvorrichtung and the locking position befindlicher locking device, the holding arm with a small distance manually further in Towards the locking position is movable, wherein the drive rod locking pin is still positively encompassed by the recess and the hook opens. The resulting locking end position of the link is due to the small distance between the drive rod locking pin and the hook to solve with manual operation with less effort of the positive connection. For a manual opening and closing of the drive rod connecting element and thus a separation and connection of the opening device of the locking device, thus only dependent on the position of the drive rod locking pin.

With manual actuation of the locking device via the actuating handle, the drive rod locking pin is movable from the locking position to the manual rotational or tilting position in a disengaged region of the drive rod connecting element and thus of the motor drive device. For this purpose, a spring tensioner is provided, which tensions the spring element and the hook relaxed and initiates the opening of the hook by means of a manually controlled displacement against the direction to open. Due to the manual separation of the opening device via an actuating handle of the locking device, a handling error is ruled out since the motor drive is completely decoupled from the manually operated locking device.

Cost-effective and easy to manufacture, it is when the spring element is designed as a leg spring or torsion spring and the spring element is pivotally connected to the hook on the support arm via a common axis of rotation. In this case, a first free end is displaceably guided in a U-shaped recess of the hook and makes with the holding arm in engagement with a bore a positive connection. The leg spring is in tensioned in the closed position Ausstellschere and located in the locking position locking device with the espagnolette locking pin with a second other free end to a flat contact with an extension of the base extending guide web spring tensioner stretched to a travel of the Ausstellschere before the rotary opening position and assumes a final position upon pivoting of the untensioned hook with the first end in the U-shaped recess.

To achieve a simple construction and a manufacturing cost-effective design of the espagnolette connecting element is provided that strikes on manual run of the locking device of the espagnolette locking pin on a run-on slope of the hook, with further actuation of the espagnolette locking pin against the spring action of the spring element the force-loaded hook opens and then occupies the trailing connecting position.

In order to achieve the simplest possible adaptation to the wing or frame so that the locking position of the locking device coincides relatively accurately with the locking end position of the motor drive, the base part is displaceable over a set screw and slotted over a slot to compensate for installation tolerances. The adjustment possibility proves to be particularly advantageous when the window or the door, for example, through different weather conditions has warped. Then a subsequent adjustment of the wing to the frame is easily possible.

In order to simplify the mounting of the base part and to achieve a mounting in the right and left usability, the base part is formed symmetrically in the longitudinal direction of the locking device.

The method for manual and motorized starting in a manually operable rotary or tilting position and motorized approach in a tilted position of a wing of a window or door is characterized in that the motorized tilting of the wing on a drive rod connecting element, in particular espagnolette locking pin, is held and that this holding for a manual turning or tilting of the wing is manually solved by means of an actuating handle, wherein with motor starting by the driving device for a manual turning or tilting the drive rod connecting element befindlicher in the closed position Ausstellschere and befindlicher in the locked position Locking device during motorized adjustment in the direction of rotation or tilt function position the drive rod locking element is automatically released from the drive rod locking pin, with release for manual rotation or tilting by motor retraction of the drive rod locking element in the closed position, wherein motorized starting the Ausstellschere from the closed position into the manually operated rotary or Kippfunktionsstellung the drive rod locking element automatically the connection to the drive rod locking pin is initiated and causes a connection wherein the Ausstellschere retracts motor in the closed position and the locking device in the locking position.

Preferably, with concerns of the wing on the frame after manual closing from the rotational or tilted position an integrated sensor triggers the automatic locking of the drive rod connecting element with the drive rod locking pin. A motor retraction into the closed position of the Ausstellschere and in the locking position of the locking device is initiated.

In the Fig. 1 an upper section of a wing 3 and a window frame 2 of a window or a door is shown, with an inventive and generally in the FIGS. 1 to 13 1 with a designated tilting in an open tilt position of a shown in this embodiment in the formation of the window or door turn-tilt wing with a wing 3 arranged locking device 4 and an attached Ausstellschere 34 shown in flared position, wherein the frame 2 a Base part 5 is concealed in a pocket not shown for receiving the same. The opening device 1 is preferably arranged between the wing 3 and the frame 2 on the upper horizontal rail 35. The wings are 3 and the frame 2 with respect to horizontal and vertical spars with folding surfaces opposite each other and have engaging behind locking elements on the locking device 4, of which - not shown - which is attached to the frame 2 and the other on the wing 3. By manual operation, also not shown, can be coupled with the locking device 4 actuating handle, the locking elements are relatively movable and engageable with each other in a locking position in engagement.

The manual actuation by means of - not shown -Betätigungshandhabe the locking device 4 also allows the connection and disconnection between the locking device 4 and the Ausstellvorrichtung 1. In this case, the manually releasable from the locking device 4 Ausstellvorrichtung 1 has a Ausstellschere 7 with a linkable to the wing 3 connecting member 8, which is a drive rod connecting element 9 and on the one hand by means of the motor drive device 6, the locking device 4 adjusted in a locking and unlocking and on the other hand, the separation in self-contained in the closed position Ausstellvorrichtung 1 and befindlichem in the locking position locking device 4 with a Espagnolette element 10 allows.

The holding arm 11 and the chain 15 are when opening by means of the motor drive device 6 with a first part of the stroke in the longitudinal direction of the base part 5 in the arrow direction Fig. 2 displaced. With a second part of the stroke, the chain 15 is in a guided exit from the base part 5 in a free field of activity after Fig. 3 transferred at an almost right angle to this base part 5, whereby the holding arm 11 is automatically pivoted. With the kinematic course of the musculoskeletal system during adjustment of the display device 1, a small size of the display device 1 is required, so that the assembly of the display device 1 in the frame 2 in almost all common Frame systems can be mounted. To achieve a high drive speed, the power-limited due to small size motor drive device 6 must be used evenly and optimally. Therefore, it is advantageous to provide a about a pivot point on the housing 36 of the base member 5 longitudinally displaceable support arm 11 which after Fig. 3 approximately centrally of the chain 15 can be controlled. The resulting stroke magnification of the support arm 11 and high chain force causes the translation of the Verrieglungsvorrichtung 4 an optimal translation for tilting the wing. 3

To Fig. 2 and Fig. 3 the drive rod connecting element 9 is arranged at the free end 18 of the holding arm 11, which consists of a recess 21 on the end face of the holding arm 11 and a hook 19, which is subjected to a force by a spring element 20. The drive rod connecting element 9 is in engagement with the drive rod locking pin 22 having the locking device 4 as the drive rod element 10 of the locking device 4 in the locked position Fig. 2 . Fig. 5 and Fig. 6 , The drive rod locking pin 22 and the drive rod connecting element 9 are the interface to the motor drive device 6 of the display device 1 and the locking device 4. In the embodiments shown, the drive rod locking pin 22 is after Fig. 5 designed as a mushroom pin, wherein the FIGS. 6 to 13 for improved illustration show the shaft of the drive rod locking pin.
