Description

Die Erfindung bezieht sich auf eine Ausstellvorrichtung für den Drehkippflügel eines Fensters oder einer Tür mit einem den Ausstellarm einer Schere stockseitig aufnehmenden Schwenklager, das aus einem Lagerbock und einem im Lagerbock drehbar gelagerten Kupplungsstück besteht, in dem der Ausstellarm mit einem Kupplungsansatz längsverschiebbar geführt und mittels eines am Kupplungsstück abgestützten Schraubentriebes längsverstellbar gehalten ist, wobei der Kupplungsansatz wenigstens einen quer zur Verschieberichtung abstehenden, durch eine in Verschieberichtung verlaufende Einführöffnung in das Kupplungsstück einführbaren Sperranschlag trägt, der ausstellarmseitig mit einem Gegenanschlag des Kupplungsstückes zusammenwirkt.The invention relates to an opening device for the tilt-and-turn sash of a window or a door with a swivel bearing which accommodates the opening arm of a pair of scissors, which consists of a bearing block and a coupling piece rotatably mounted in the bearing block, in which the opening arm is guided in a longitudinally displaceable manner and by means of a coupling attachment on the coupling piece supported screw drive is held longitudinally adjustable, the coupling projection carries at least one locking stop protruding transversely to the displacement direction and insertable into the coupling piece through an insertion opening running in the displacement direction, which interacts on the extension arm side with a counter-stop of the coupling piece.

Die längsverstellbare Halterung des Ausstellarmes einer Schere für den Drehkippflügel eines Fensters oder einer Tür bietet bei Ausstellvorrichtungen der oben angegebenen Art, wie sie beispielsweise aus der DE-OS 3023468 bekannt sind, eine einfache Möglichkeit, einerseits Herstellungsungenauigkeiten ausgleichen und andererseits sich während der Benutzung ergebende Veränderungen berücksichtigen zu können, weil mit der Verstellung der wirksamen Länge des Ausstellarmes der Abstand des Flügels vom Schwenklager und damit die Lage des Flügels gegenüber dem Stock eingestellt wird. Die Längsverstellung mittels eines Schraubentriebes, der vorzugsweise aus einer am Kupplungsstück abgestützten und in ein Muttergewinde im Kupplungsansatz des Ausstellarmes eingreifenden Stellschraube besteht, stellt dabei eine einfache Handhabung bei einer raumsparenden Konstruktion sicher, allerdings mit dem Nachteil, daß es keine Sicherheit gegen ein unbeabsichtigtes Herausschrauben der Stellschraube aus dem Muttergewinde des Kupplungsansatzes gibt, so daß es beispielsweise nach einer längeren Benützung der Ausstellvorrichtung zu einem unbemerkten Lösen der zugfesten Verbindung zwischen dem Kupplungsansatz des Ausstellarmes und dem Kupplungsstück des Schwenklagers kommen kann. Der Flügel verliert somit seine Verbindung zu seinem oberen Schwenklager, und es besteht die Gefahr, daß er bei einer entsprechenden Belastung aus dem Stock fällt.The longitudinally adjustable holder of the stay arm of a pair of scissors for the tilt-and-turn sash of a window or door offers a simple possibility for opening devices of the type specified above, as are known, for example, from DE-OS 3023468, on the one hand to compensate for manufacturing inaccuracies and, on the other hand, to result in changes during use be able to take into account, because with the adjustment of the effective length of the extension arm, the distance of the wing from the pivot bearing and thus the position of the wing relative to the stick is adjusted. The longitudinal adjustment by means of a screw drive, which preferably consists of a set screw supported on the coupling piece and engaging in a nut thread in the coupling shoulder of the extension arm, ensures simple handling with a space-saving construction, but with the disadvantage that there is no security against unintentional unscrewing of the Set screw from the nut thread of the coupling attachment, so that there is an undetected loosening of the tension-resistant connection between the coupling attachment, for example after prolonged use of the opening device of the extension arm and the coupling piece of the swivel bearing. The wing thus loses its connection to its upper pivot bearing, and there is a risk that it will fall out of the stick under a corresponding load.

Der Erfindung liegt folglich die Aufgabe zugrunde, diesen Mangel zu vermeiden und eine Ausstellvorrichtung für den Drehkippflügel eines Fensters oder einer Tür der eingangs geschilderten Art mit einfachen Mitteln so zu verbessern, daß ein unbeabsichtigtes Lösen des Kupplungsansatzes des Ausstellarmes vom Kupplungsstück des Schwenklagers ausgeschlossen wird.The invention is therefore based on the object to avoid this deficiency and to improve an opening device for the tilt-and-turn sash of a window or door of the type described above with simple means that an unintentional release of the coupling approach of the opening arm from the coupling piece of the pivot bearing is excluded.

Die Erfindung löst die gestellte Aufgabe dadurch, daß für den Sperranschalg des Kupplungsansatzes im Kupplungsstück auf der dem Ausstellarm abgewandten Seite des Gegenanschlages eine Führungsnut in Verschieberichtung vorgesehen ist und daß das Kupplungsstück zwischen der Führungsnut und der dazu winkelversetzten Einführöffnung einen Quergang für den Sperranschlag bildet.The invention solves this problem in that a guide groove is provided in the direction of displacement for the locking flange of the coupling approach in the coupling piece on the side of the counterstop facing away from the extension arm and in that the coupling piece forms a transverse passage for the locking stop between the guide groove and the angularly offset insertion opening.

Durch das Vorsehen eines mit einem ausstellarmseitigen Gegenanschlag des Kupplungsstückes zusammenwirkenden Sperranschalg am Kupplungsansatz wird der mögliche Verschiebeweg des Kupplungsansatzes innerhalb des Kupplungsstückes in der Ausziehrichtung begrenzt, weil eben der Sperranschlag nach einem vorgegebenen Ausziehweg des Kupplungsansatzes am Gegenanschlag anschlägt. Selbst wenn sich der Stellbereich des Schraubentriebes nicht bis zu dieser Anschlagslage des Kupplungsansatzes erstreckt und den Kupplungsansatz bereits vor dem Erreichen der Anschlagslage freigibt, kann der Kupplungsansatz nicht unbeabsichtigt aus dem Kupplungsstück austreten.The provision of a locking collar on the coupling shoulder, which interacts with a counterstop of the coupling piece on the extension arm, limits the possible displacement path of the coupling shoulder within the coupling piece in the pull-out direction because the locking stop strikes the counterstop after a predetermined pull-out path of the coupling shoulder. Even if the adjustment range of the screw drive does not extend up to this stop position of the coupling attachment and releases the coupling attachment before the stop position is reached, the coupling attachment cannot unintentionally emerge from the coupling piece.

Der Sperranschlag kann wie auch der Gegenanschlag nach dem Einführen des Kupplungsansatzes in das Kupplungsstück angebracht werden, beispielsweise durch ein Einschlagen eines Anschlagstiftes in den Kupplungsansatz durch eine entsprechendes Langloch im Kupplungsstück. Um beim Zusammenbau des Ausstellarmes mit seinem Schwenklager das zusätzliche Anbringen von Anschlägen zu vermeiden, kann in weiterer Ausbildung der Erfindung das Kupplungsstück zumindest eine gegenüber dem Gegenanschlag winkelversetzte, in Verschieberichtung verlaufende Einführöffnung für den Sperranschlag mit einem Quergang zum Gegenanschlag aufweisen. Zum Einführen des Kupplungsansatzes des Ausstellarmes in das mit einer entsprechenden Aufnahmeöffnung versehene Kupplungsstück ist folglich der Ausstellarm zunächst gegenüber seiner Gebrauchslage um seine Längsachse zu verdrehen, so daß der quer zur Verschieberichtung vorragende Sperranschlag des Kupplungsansatzes in die hiefür vorgesehene Einführöffnung im Kupplungsstück eingreifen kann. Gelangt der Sperranschlag in den Bereich des Querganges, so kann der Ausstellarm in seine Gebrauchslage verdreht werden, wobei der Sperranschlag den Gegenanschlag im Kupplungsstück hintergreift. Mit dem Angriff des Schraubentriebes am Kupplungsansatz kann dann der Ausstellarm verkürzt und der Flügel gegen das Schwenklager gezogen werden. Das Lösen des Ausstellarmes vom Kupplungsstück erfolgt in umgekehrter Reihenfolge, indem der Kupplungsansatz aus der Anschlagslage entsprechend der Winkelversetzung zwischen dem Gegenanschlag und der Einführöffnung verdreht wird, damit der Sperranschlag entlang des Querganges zwischen dem Gegenanschlag und der Einführöffnung in den Bereich der Einführöffnung gelangt und dann durch die Einführöffnung in Verschieberichtung des Kupplungsansatzes aus dem Kupplungsstück herausgezogen werden kann.The blocking stop, like the counterstop, can be attached after the coupling attachment has been inserted into the coupling piece, for example by driving one in Stop pin in the coupling attachment through a corresponding slot in the coupling piece. In order to avoid the additional attachment of stops when assembling the extension arm with its swivel bearing, in a further development of the invention the coupling piece can have at least one insertion opening for the locking stop, which is angularly offset in relation to the counterstop and runs in the direction of displacement, with a transverse passage to the counterstop. To insert the coupling approach of the extension arm into the coupling piece provided with a corresponding receiving opening, the extension arm must therefore first be rotated about its longitudinal axis with respect to its position of use, so that the locking stop of the coupling extension projecting transversely to the direction of displacement can engage in the insertion opening provided for this purpose in the coupling piece. If the locking stop reaches the area of the cross aisle, the extension arm can be turned into its position of use, the locking stop engaging behind the counter stop in the coupling piece. With the attack of the screw drive on the coupling attachment, the extension arm can then be shortened and the sash pulled against the swivel bearing. The release arm is released from the coupling piece in the reverse order in that the coupling attachment is rotated from the stop position in accordance with the angular displacement between the counterstop and the insertion opening, so that the locking stop along the cross passage between the counterstop and the insertion opening reaches the area of the insertion opening and then through the insertion opening can be pulled out of the coupling piece in the direction of displacement of the coupling attachment.

Um eine Verdrehung des Ausstellarmes gegenüber dem Kupplungsstück zu unterbinden, ist es bekannt, den Kupplungsansatz mit seitlich abstehenden Führungsnasen zu versehen, die in entsprechende Führungsnuten des Kupplungsstückes eingreifen. Dieser Vorteil kann auch bei einer erfindungsgemäßen Ausstellvorrichtung ausgenützt werden, wobei sich besonders einfache Konstruktionsverhältnisse dadurch ergeben, daß für den Sperranschlag des Kupplungsansatzes im Kupplungsstück auf der dem Ausstellarm abgewandten Seite des Gegenanschlages eine Führungsnut in Verschieberichtung vorgesehen ist. Durch diese Maßnahme kann der Sperranschlag selbst für die Drehsicherung des Ausstellarmes herangezogen werden, so daß sich gesonderte Führungsnasen erübrigen. Die Führungsnut darf allerdings nur auf der dem Ausstellarm abgewandten Seite des Gegenanschlages vorgesehen sein, um die für das Einführen des Sperranschlages notwendige Verdrehung des Ausstellarmes sicherzustellen.In order to prevent the extension arm from rotating relative to the coupling piece, it is known to provide the coupling attachment with laterally projecting guide lugs which engage in corresponding guide grooves in the coupling piece. This advantage can also be exploited in a display device according to the invention, whereby simple design conditions result in that a guide groove is provided in the direction of displacement for the locking stop of the coupling approach in the coupling piece on the side of the counterstop facing away from the deployment arm. As a result of this measure, the locking stop itself can be used for the anti-rotation lock of the extension arm, so that there is no need for separate guide lugs. However, the guide groove may only be provided on the side of the counterstop facing away from the deployment arm in order to ensure the twisting of the deployment arm necessary for the insertion of the locking stop.

Erstreckt sich der Stellbereich des Schraubentriebes für die Längsverstellung des Ausstellarmes zumindest bis zur Anschlagstellung des Sperranschlages am Gegenanschlag, so kann der Ausstellarm über den gesamten, durch den Gegenanschlag des Kupplungsstückes begrenzten Verschiebeweg des Kupplungsansatzes mit Hilfe des Schraubentriebes verstellt werden, ohne daß es zu einer freien Verschiebelänge kommt, in deren Bereich der Gewindeeingriff des Schraubentriebes gelöst ist. Nach dem Verdrehen des Ausstellarmes in seine Gebrauchslage wird somit der Gewindeeingriff des Schraubentriebes beim Verdrehen der Stellschraube erzwungen.If the adjustment range of the screw drive for the longitudinal adjustment of the extension arm extends at least up to the stop position of the locking stop on the counter-stop, the extension arm can be adjusted with the help of the screw drive over the entire displacement path of the coupling attachment limited by the counter-stop of the coupling piece, without causing a free movement Displacement length comes in the area of which the threaded engagement of the screw drive is released. After turning the extension arm into its position of use, the threaded engagement of the screw drive is thus forced when the adjusting screw is turned.

Weist schließlich der Quergang eine Steigung im Anziehdrehsinn des Schraubentriebes auf, so kann in einfacher Weise die Verdrehung des Ausstellarmes aus der Montagestellung in die Gebrauchslage beim Einziehen des Kupplungsansatzes in das Kupplungsstück mit Hilfe des Schraubentriebes erreicht werden. Der Quergang bildet ja eine entsprechende Führung für den Sperransatz, der bei einer Längsverstellung des Kupplungsansatzes entlang dieser Führung zufolge der Steigung des Querganges verdreht wird.Finally, if the transverse gear has an incline in the tightening direction of rotation of the screw drive, the twisting of the extension arm from the assembly position into the position of use when pulling the coupling attachment into the coupling piece can be achieved with the aid of the screw drive. The transverse gear forms a corresponding guide for the locking projection, which is rotated when the coupling projection is adjusted longitudinally along this guide due to the gradient of the transverse gear.

Das dargestellte Schwenklager einer üblichen Ausstellvorrichtung für den Drehkippflügel eines Fensters oder einer Tür besteht in herkömmlicher Weise aus einem am Tür- oder Fensterstock zu befestigenden Lagerbock 1 (Fig. 3) und einem in diesem Lagerbock 1 mittels eines Lagerbolzens 2 drehbar gelagerten Kupplungsstück 3, das eine Aufnahmeöffnung 4 für den Kupplungsansatz 5 des Ausstellarmes 6 einer nicht näher dargestellten Schere aufweist. Dieser zylindrische Kupplungsansatz 5 greift in die zylindrische Aufnahmeöffnung 4 des Kupplungsstückes ein und kann mit Hilfe eines Schraubentriebes 7 gegenüber dem Kupplungsstück 3 verstellt werden. Zu diesem Zweck greift die Stellschraube 8, die sich an der dem Ausstellarm 6 abgewandten Stirnseite 9 (Fig. 2) an dem Kupplungsstück 3 abstützt, in eine Gewindebohrung des Kupplungsansatzes 5 ein.The swivel bearing shown of a conventional opening device for the tilt-and-turn sash of a window or a door consists in a conventional manner of a bracket 1 to be fastened to the door or window frame (FIG. 3) and a coupling piece 3 rotatably mounted in this bracket 1 by means of a bearing bolt 2 has a receiving opening 4 for the coupling extension 5 of the extension arm 6 of a pair of scissors, not shown. This cylindrical coupling projection 5 engages in the cylindrical receiving opening 4 of the coupling piece and can be adjusted with respect to the coupling piece 3 with the aid of a screw drive 7. For this purpose, the adjusting screw 8, which is supported on the coupling arm 3 on the end 9 facing away from the deployment arm 6 (FIG. 2), engages in a threaded bore of the coupling projection 5.

Neu gegenüber Schwenklagern für die Schere eines Drehkippflügels ist, daß der Kupplungsansatz 5 wenigstens einen Sperranschlag 10, vorzugsweise jedoch zwei einander diametral gegenüberliegende, quer zur Verschieberichtung abstehende Sperranschläge 10 aufweist, die mit entsprechenden Gegenanschlägen 11 zusammenwirken, so daß der Kupplungsansatz 5 des Ausstellarmes 6 auch bei gelöster Stellschraube 8 nicht aus der Aufnahmeöffnung 4 des Kupplungsstückes 3 herausgezogen werden kann. Diese Begrenzung des Verschiebeweges des Ausstellarmes 6 macht gegenüber den Gegenanschlägen 11 winkelversetzte Einführöffnungen 12 mit je einem Quergang 13 zum Gegenanschlag 11 hin für die Sperranschläge 10 notwendig, damit der Ausstellarm 6 aus der gedrehten Einführstellung, wie sie in Fig. 1 dargestellt ist, in die dazu gedrehte Gebrauchslage verschwenkt werden kann, in der die Sperranschläge 10 mit den Gegenanschlägen 11 zusammenwirken.New compared to pivot bearings for the scissors of a tilt and turn wing is that the coupling projection 5 has at least one locking stop 10, but preferably two diametrically opposite locking stops 10 projecting transversely to the direction of displacement, which interact with corresponding counter-stops 11, so that the coupling projection 5 of the extension arm 6 also when the adjusting screw 8 is loosened, it cannot be pulled out of the receiving opening 4 of the coupling piece 3. This limitation of the displacement of the extension arm 6 makes compared to the counter-stops 11 angularly displaced insertion openings 12, each with a transverse passage 13 to the counter-stop 11 necessary for the locking stops 10, so that the extension arm 6 can be pivoted from the rotated insertion position, as shown in FIG. 1, into the rotated position of use, in which the locking stops 10 cooperate with the counter stops 11.

Für die Längsverstellung des Kupplungsansatzes 5 innerhalb des Kupplungsstückes 3 sind auf der dem Ausstellarm 3 abgewandten Seite der Gegenanschläge Führungsnuten 14 für die Sperranschläge 10 vorgesehen, die somit zugleich eine Drehsicherung für den Ausstellarm 6 im Bereich seiner Längsverstellung bilden. Diese Führungsnuten 14 können allerdings nur auf der dem Ausstellarm 6 abgewandten Seite der Gegenanschläge 11 angeordnet werden, um die für das Hintergreifen der Gegenanschläge 11 notwendige Verdrehung der Sperranschläge 10 beim Einführen des Ausstellarmes 6 in das Kupplungsstück 3 zu sichern.For the longitudinal adjustment of the coupling projection 5 within the coupling piece 3, guide grooves 14 for the locking stops 10 are provided on the side of the counter-stops facing away from the extension arm 3, which thus simultaneously form a rotation lock for the extension arm 6 in the region of its longitudinal adjustment. However, these guide grooves 14 can only be arranged on the side of the counter-stops 11 facing away from the deployment arm 6 in order to secure the rotation of the locking stops 10 necessary for engaging behind the counter-stops 11 when the deployment arm 6 is inserted into the coupling piece 3.

Wird der Kupplungsansatz 5 gemäß Fig. 1 so in die Aufnahmeöffnung 4 des Kupplungsstückes 3 eingeführt, daß die Sperranschläge 10 durch die in Verschieberichtung verlaufenden Einführöffnungen 12 in den Bereich der Quergänge 13 gelangen, so kann der Ausstellarm aus der Montagestellung in die Gebrauchslage verdreht werden und die Stellschraube 8 des Schraubentriebes 7 in die Gewindebohrung des Kupplungsansatzes 5 eingreifen, wobei sich besonders vorteilhafte Verhältnisse dann ergeben, wenn der Stellschraubeneingriff bereits im Bereich der Quergänge 13 einsetzt, weil in diesem Fall der gesamte Verschiebeweg für die Verstellung des Ausstellarmes durch die Stellschraube 8 ausgenützt werden kann. Außerdem ergibt sich eine einfache Handhabung beim Einsetzen des Kupplungsansatzes 5 des Ausstellarmes 6 in das Kupplungsstück 3. Mit dem Anziehen der Stellschraube 8 wird der Kupplungsansatz 5 tiefer in die Aufnahmeöffnung 4 des Kupplungsstückes 3 eingezogen, wobei die Sperranschläge 10 von den Gegenanschlägen 11 abheben und in die Führungsnuten 14 eingreifen.1 is inserted into the receiving opening 4 of the coupling piece 3 in such a way that the locking stops 10 pass through the insertion openings 12 extending in the direction of displacement into the region of the transverse aisles 13, the extension arm can be rotated from the assembly position into the position of use and the set screw 8 of the screw drive 7 engage in the threaded bore of the coupling projection 5, which results in particularly advantageous conditions when the set screw engagement already starts in the area of the transverse gears 13, because in this case the entire displacement path is used for the adjustment of the extension arm by the set screw 8 can be. In addition, there is simple handling when inserting the coupling projection 5 of the extension arm 6 into the coupling piece 3. When the adjusting screw 8 is tightened, the coupling projection 5 is drawn deeper into the receiving opening 4 of the coupling piece 3, the locking stops 10 Lift off the counter stops 11 and engage in the guide grooves 14.
