Ausstellscheren der vorstehenden Art sind als sogenannte "Friktionsscheren" gebräuchlich. Mittels einer derartigen Ausstellschere wird beispielsweise ein Fensterflügel in einer Öffnungsstellung gegenüber einem zugehörigen festen Rahmen vorläufig gesichert.Display scissors of the above type are used as so-called "friction scissors". A window sash, for example, is temporarily secured in an open position with respect to an associated fixed frame by means of such an opening scissor.

Gattungsgemäßer Stand der Technik ist offenbart in GB 2 081 803 A . Diese Druckschrift betrifft ein Fenster mit einer als Friktionsschere ausgebildeten Ausstellschere zwischen einem Fensterflügel und einem feststehenden Fensterrahmen. Zwei der Arme der Ausstellschere sind dabei an einem Gleiter schwenkbar angelenkt, der seinerseits an einer mit dem festen Fensterrahmen verbundenen Führungsschiene längs der Hauptebene des festen Fensterrahmens beweglich geführt ist. Die Führungsschiene besitzt einen C-förmigen Querschnitt und bildet die Nutwand einer Führungsnut mit einem Nutgrund und einer dem Nutgrund gegenüberliegenden Nutöffnung aus. Längsränder der Nutöffnung werden durch den in die Führungsschiene eingeschobenen Gleiter hintergriffen und stützen dadurch den Gleiter an der von dem Nutgrund der Führungsnut abliegenden Seite ab. An der dem Nutgrund zugewandten Unterseite ist der Gleiter mit einer zu dem Nutgrund hin mündenden Aussparung versehen, in die ein plattenförmiges Bremselement lose eingelegt ist.

This document relates to a window with a scissor stay designed as friction scissors between a window sash and a fixed window frame. Two of the arms of the scissor display are pivotably articulated on a slider, which in turn is movably guided along the main plane of the fixed window frame on a guide rail connected to the fixed window frame. The guide rail has a C-shaped cross section and forms the groove wall of a guide groove with a groove base and a groove opening opposite the groove base. Longitudinal edges of the groove opening are engaged from behind by the slider pushed into the guide rail and thereby support the slider on the side remote from the groove base of the guide groove. On the underside facing the groove base, the slider is provided with a recess opening towards the groove base, into which a plate-shaped braking element is loosely inserted. By means of a set screw which engages in a thread on the slider and which can be adjusted perpendicular to the groove base of the guide groove, the pressure of the braking element on the groove base and thereby the resistance to movement can be varied, which the braking element associated with the opening and closing movements of the window sash Opposite movements of the slider along the guide rail.

Bei der Montage des Gleiters und des Bremselements an der Führungsschiene besteht die Gefahr, dass das Bremselement verloren geht. Wird der Gleiter versehentlich ohne das Bremselement montiert und wird in Unkenntnis dieses Umstands zur Einstellung der Bremswirkung des Bremselements die Stellschraube für das Bremselement in Richtung auf den Nutgrund der Führungsnut für den Gleiter zugestellt, so ergibt sich ein unmittelbarer Kontakt zwischen dem Nutgrund der Führungsnut einerseits und der Spitze der Stellschraube andererseits. Bewegungen des Fensterflügels relativ zu dem festen Fensterrahmen und damit verbundene Bewegungen des Gleiters längs der festrahmigen Führungsschiene führen in diesem Fall zu einer Beschädigung der Führungsschiene.When mounting the slider and the braking element on the guide rail, there is a risk that the braking element will be lost. If the slider is accidentally mounted without the braking element and if, in ignorance of this fact, to adjust the braking effect of the braking element, the adjusting screw for the braking element is advanced towards the groove base of the guide groove for the slider, there is direct contact between the groove base of the guide groove on the one hand and the tip of the set screw on the other hand. Movements of the window sash relative to the fixed window frame and associated movements of the slider along the fixed-frame guide rail lead in this case to damage to the guide rail.

An eccentric is rotatably mounted on the slider about an axis which runs perpendicular to the base of the guide groove. By rotating about the axis mentioned, the eccentric is advanced against the side walls of the guide groove and is thus braced between the side walls of the guide groove and the slider.

Ausgehend von dem gattungsgemäßen Stand der Technik besteht die Aufgabe der vorliegenden Erfindung darin, Montagefehler der beschriebenen Art und damit unter Umständen verbundene Fehlfunktionen und Schäden an dem betreffenden Fenster, der betreffenden Tür oder dergleichen zu verhindern.Based on the generic prior art, the object of the present invention is to prevent assembly errors of the type described and possibly associated malfunctions and damage to the relevant window, the relevant door or the like.

Erfindungsgemäß gelöst wird diese Aufgabe durch das Fenster, die Tür oder dergleichen gemäß Patentanspruch 1.According to the invention, this object is achieved by the window, door or the like according to claim 1.

Anspruchsgemäß ist ein Bremselement, mittels dessen bei Bewegungen des mit dem Bremselement versehenen Führungsstücks längs der zugeordneten Führungsnut eine Bremswirkung erzeugt werden kann, jedenfalls bei der Montage des Führungsstücks unverlierbar an diesem gehalten. Dabei ist zwischen dem Führungsstück und dem Bremselement eine Bauteilverbindung vorgesehen, welche nach der Montage des Führungsstücks und des Bremselements an der Führungsnut die Zustellbarkeit des Bremselements relativ zu dem Führungsstück und somit die Regulierbarkeit der mittels des Bremselements erzielbaren Bremswirkung nicht beeinträchtigt.According to the claim, a braking element, by means of which a braking effect can be generated when the guide piece provided with the braking element moves along the associated guide groove, is held captive on the guide piece during assembly. It is between the Guide piece and the braking element a component connection is provided which, after the assembly of the guide piece and the braking element on the guide groove, does not impair the adjustability of the braking element relative to the guide piece and thus the controllability of the braking effect that can be achieved by means of the braking element.

Nur wenn das Bremselement relativ zu dem Führungsstück in eine Position bewegt ist, bei welcher der gemeinschaftliche Querschnitt des Führungsstücks und des Bremselements innerhalb des Querschnitts der Führungsnut liegt, kann das Führungsstück mit dem Bremselement in der Einschubrichtung vollständig in die Führungsnut eingeführt werden.Only when the brake element is moved relative to the guide piece into a position in which the common cross section of the guide piece and the brake element lies within the cross section of the guide groove can the guide piece with the brake element be completely inserted into the guide groove in the insertion direction.

Der Überstand des Bremselements gegenüber dem Führungsstück, aufgrund dessen der gemeinschaftliche Querschnitt des Führungsstücks und des Bremselements ein Übermaß gegenüber dem Querschnitt der zugeordneten Führungsnut aufweist, wird im Falle der Erfindung bei der Montage des Führungsstücks selbsttätig beseitigt, indem das Bremselement mittels der Bauteilverbindung an dem Führungsstück relativ zu diesem um eine senkrecht zu der Einschubrichtung verlaufende Schwenkachse schwenkbar gehalten ist und die an dem Führungsstück vorgesehene Aufnahme für das Bremselement in der Einschubrichtung hinter der Bauteilverbindung zwischen dem Führungsstück und dem Bremselement angeordnet ist. Das Bremselement, das an dem Führungsstück um eine senkrecht zu der Einschubrichtung verlaufende Schwenkachse schwenkbar gelagert ist, ist in der Lage, beim Einschieben des Führungsstücks in die Führungsnut aufgrund einer damit verbundenen Beaufschlagung durch die Wand der Führungsnut selbsttätig eine Schwenkbewegung gegenüber dem Führungsstück auszuführen und dabei in die für das Bremselement vorgesehene Aufnahme an dem Führungsstück einzuschwenken. Eine derartige selbsttätige Reduzierung des gemeinschaftlichem Querschnitts des Führungsstücks und des Bremselements auf den Querschnitt der Führungsnut ist erfindungsgemäß deshalb möglich, weil bei der Montage die an dem Führungsstück vorgesehene Aufnahme für das Bremselement der Bauteilverbindung zwischen dem Führungsstück und dem Bremselement in der Einschubrichtung nacheilt. Aufgrund dieses Erfindungsmerkmals befindet sich die an dem Führungsstück vorgesehene Aufnahme für das Bremselement bei der Montage noch zumindest teilweise außerhalb der Führungsnut, wenn die Bauteilverbindung zwischen dem Führungsstück und dem Bremselement die Führungsnut erreicht. Eine fortgesetzte Einschubbewegung des Führungsstücks hat dann zur Folge, dass das über die Bauteilverbindung an dem Führungsstück gehaltene Bremselement selbsttätig zu demjenigen Bereich des Führungsstücks hin schwenkt, in welchem die Aufnahme für das Bremselement vorgesehen ist und der für das Bremselement folglich die Möglichkeit bietet, in eine Schwenkstellung zu gelangen, in welcher der gemeinschaftliche Querschnitt des Führungsstücks und des Bremselements innerhalb des Querschnitts der Führungsnut liegt.The protrusion of the braking element relative to the guide piece, due to which the common cross-section of the guide piece and the braking element has an excess compared to the cross-section of the associated guide groove, is automatically eliminated in the case of the invention when the guide piece is assembled by the braking element by means of the component connection on the guide piece is held pivotable relative to this about a pivot axis running perpendicular to the insertion direction and the receptacle for the braking element provided on the guide piece is arranged in the insertion direction behind the component connection between the guide piece and the braking element. The braking element, which is pivotably mounted on the guide piece about a pivot axis running perpendicular to the insertion direction, is able to automatically execute a pivoting movement relative to the guide piece when the guide piece is pushed into the guide groove due to an associated action by the wall of the guide groove and thereby to pivot into the receptacle provided for the braking element on the guide piece. Such an automatic reduction of the common cross-section of the guide piece and the brake element to the cross-section of the guide groove is possible according to the invention because during assembly the receptacle for the brake element provided on the guide piece lags behind the component connection between the guide piece and the brake element in the insertion direction. Due to this feature of the invention, the receptacle for the braking element provided on the guide piece is still at least partially outside the guide groove during assembly. when the component connection between the guide piece and the braking element reaches the guide groove. A continued insertion movement of the guide piece then has the consequence that the brake element held on the guide piece via the component connection automatically pivots towards that area of the guide piece in which the receptacle for the brake element is provided and which consequently offers the possibility for the brake element to move into a To reach pivoting position in which the common cross section of the guide piece and the braking element is within the cross section of the guide groove.

Generell ist es von Vorteil, wenn das Bremselement mittels der Bauteilverbindung schwenkbar an dem Führungsstück gelagert ist. Aufgrund der Schwenkbeweglichkeit kann das Bremselement außerhalb der Führungsnut, beispielsweise auf dem Transport zum Einbauort, bei einer entsprechenden Beanspruchung eine Ausweichbewegung ausführen, ohne dass eine Beschädigung der Bauteilverbindung zu befürchten wäre.In general, it is advantageous if the braking element is pivotably mounted on the guide piece by means of the component connection. Due to the pivoting mobility, the braking element can perform an evasive movement outside the guide groove, for example during transport to the installation site, in the event of a corresponding load, without having to fear damage to the component connection.

Besondere Ausführungsarten des Fensters, der Tür oder dergleichen gemäß Patentanspruch 1 ergeben sich aus den abhängigen Patentansprüchen 2 bis 9.Special embodiments of the window, the door or the like according to claim 1 result from the dependent claims 2 to 9.

Insbesondere aus Gründen der Lastaufnahmefähigkeit ist das Führungsstück in bevorzugter Ausgestaltung der Erfindung als Verbundbauteil mit einem metallenen Träger und einem mit dem metallenen Träger verbundenen Kunststoffanteil ausgebildet, wobei insbesondere aus fertigungstechnischen Gründen die Bauteilverbindung zwischen dem Führungsstück und dem Bremselement zwischen dem Kunststoffanteil des Führungsstücks und dem Bremselement vorgesehen ist (Patentanspruch 2).In a preferred embodiment of the invention, the guide piece is designed as a composite component with a metal support and a plastic component connected to the metal support, in particular for reasons of load-bearing capacity, with the component connection between the guide piece and the braking element between the plastic component of the guide piece and the braking element, especially for manufacturing reasons is provided (claim 2).

Gemäß den Patenansprüchen 3 und 4 ist der metallene Träger des als Verbundbauteil ausgebildeten Führungsstücks mit einer Zustellvorrichtung zum Zustellen des Bremselements versehen, wobei die Zustellvorrichtung an dem metallenen Träger des Führungsstücks vorzugsweise als Gewinde für eine Stellschraube ausgebildet ist, mittels derer das Bremselement relativ zu dem Führungsstück zugestellt werden kann. Die infolge des Einspannens des Bremselements zwischen dem Nutgrund der Führungsnut und dem Führungsstück auftretenden Kräfte werden folglich über den lastaufnahmefähigeren Teil des Führungsstücks abgetragen.According to patent claims 3 and 4, the metal carrier of the guide piece designed as a composite component is provided with a feed device for feeding the braking element, the feed device on the metal carrier of the guide piece preferably being designed as a thread for an adjusting screw, by means of which the braking element is relative to the guide piece can be delivered. The forces occurring as a result of the clamping of the braking element between the groove base of the guide groove and the guide piece are consequently removed over the load-bearing part of the guide piece.

Aus entsprechenden Gründen ist im Falle der Erfindungsbauart gemäß Patentanspruch 5 vorgesehen, dass das in die Führungsnut eingeschobene Führungsstück an dem metallenen Träger von einer Nutwand der Führungsnut parallel zu dem Nutgrund übergriffen wird. Über den metallenen Träger können folglich Kräfte, die aufgrund der Einspannung des Bremselements zwischen dem Nutgrund der Führungsnut und dem Führungsstück auf das Führungsstück wirken, in die Nutwand der Führungsnut und über die Nutwand in den mit der Führungsnut versehenen festen Rahmen oder Flügel abgetragen werden.For corresponding reasons, it is provided in the case of the inventive design according to claim 5 that the guide piece inserted into the guide groove on the metal carrier is overlapped by a groove wall of the guide groove parallel to the groove base. Via the metal support, forces that act on the guide piece due to the clamping of the braking element between the groove base of the guide groove and the guide piece can consequently be transferred into the groove wall of the guide groove and via the groove wall into the fixed frame or wing provided with the guide groove.

Ausweislich Patentanspruch 6 übernimmt in Weiterbildung der Erfindung der Kunststoffanteil des als Verbundbauteil ausgeführten Führungsstücks dessen Führung in der zugeordneten Führungsnut. Bei entsprechender Materialwahl für den Kunststoffanteil des Führungsstücks ist auf diese Art und Weise insbesondere eine reibungs- und verschleißarme Führung des Führungsstücks in der Führungsnut gewährleistet.According to patent claim 6, in a further development of the invention, the plastic portion of the guide piece designed as a composite component takes over its guidance in the assigned guide groove. With an appropriate choice of material for the plastic portion of the guide piece, in particular a low-friction and low-wear guidance of the guide piece in the guide groove is ensured in this way.

Eine aus Fertigungsgründen bevorzugte Erfindungsbauart ist Gegenstand von Patentanspruch 7. Das Führungsstück und das Bremselement sind dabei jeweils wenigstens teilweise als Kunststoff-Spritzteil ausgebildet und unter Ausbildung der Bauteilverbindung aneinander angespritzt.A preferred embodiment of the invention for manufacturing reasons is the subject matter of claim 7. The guide piece and the braking element are each at least partially formed as a plastic injection-molded part and are molded onto one another to form the component connection.

Ebenfalls aus fertigungstechnischen Gründen ist ausweislich Patentanspruch 8 die Bauteilverbindung zwischen dem Führungsstück dem Bremselement als Filmscharnier ausgebildet.Also for manufacturing reasons, according to patent claim 8, the component connection between the guide piece and the braking element is designed as a film hinge.

Grundsätzlich besteht erfindungsgemäß die Möglichkeit, dass das Bremselement über die Bauteilverbindung dauerhaft an dem Führungsstück fixiert ist. Ausweislich Patentanspruch 9 ist es erfindungsgemäß aber auch denkbar, dass die Bauteilverbindung zwischen dem Führungsstück und dem Bremselement nur Bestand hat, bis nach der Montage des Führungsstücks und des Bremselements an der zugeordneten Führungsnut das Bremselement erstmalig gegen den Nutgrund der Führungsnut zugestellt wird. Eine erstmalige Zustellbewegung des Bremselements gegenüber dem Führungsstück bewirkt im Falle dieser Erfindungsbauart eine Zerstörung der zwischen dem Führungsstück und dem Bremselement vorgesehenen Bauteilverbindung. Infolgedessen ist eine Behinderung der Zustellbewegung des Bremselements gegenüber dem Führungsstück durch die Bauteilverbindung mit Sicherheit ausgeschlossen.In principle, according to the invention, there is the possibility that the braking element is permanently fixed to the guide piece via the component connection. According to patent claim 9, it is also conceivable according to the invention that the component connection between the guide piece and the braking element only lasts until after the guide piece and the braking element have been mounted on the associated guide groove, the braking element first against the groove base of the Guide groove is fed. In the case of this type of construction of the invention, an initial feed movement of the brake element with respect to the guide piece destroys the component connection provided between the guide piece and the brake element. As a result, an obstruction of the feed movement of the braking element with respect to the guide piece by the component connection is definitely excluded.

Nachfolgend wird die Erfindung anhand beispielhafter schematischer Darstellungen näher erläutert. Es zeigen:

Gemäß Figur 1 umfasst ein Fenster 1 einen festen Rahmen 2 sowie einen nach außen öffnenden Flügel 3. Eine zwischen dem festen Rahmen 2 und dem Flügel 3 angeordnete Ausstellschere 4 verbindet den Flügel 3 mit dem festen Rahmen 2 und ermöglicht Bewegungen des Flügels 3 relativ zu dem festen Rahmen 2 um eine vertikale Drehachse. Eine mit der in Figur 1 dargestellten Ausstellschere 4 baugleiche Ausstellschere ist längs der Flügeldrehachse von der Ausstellschere 4 beabstandet und an der außerhalb des Darstellungsausschnitts von Figur 1 liegenden oberen Ecke des Flügels 3 vorgesehen.According to Figure 1 A window 1 comprises a fixed frame 2 and a sash 3 that opens outwards. A scissor stay 4 arranged between the fixed frame 2 and the sash 3 connects the sash 3 to the fixed frame 2 and enables the sash 3 to move relative to the fixed frame 2 around a vertical axis of rotation. One with the in Figure 1 Display scissors shown 4 identical display scissors is spaced along the sash axis of rotation from the display scissors 4 and on the outside of the detail of Figure 1 lying upper corner of the wing 3 is provided.

Die Ausstellschere 4 umfasst einen Ausstellarm 5, der mit einem Ende an dem festen Rahmen 2 und dem anderen Ende an dem Flügel 3 schwenkbar gelagert ist. Die festrahmenseitige Drehachse und die flügelseitige Drehachse des Ausstellarms 5 verlaufen parallel zueinander in vertikaler Richtung. Ein festrahmenseitiges Schwenklager 6 des Ausstellarms 5 ist relativ zu dem festen Rahmen 2 ortsunveränderlich. Entsprechend ist ein in Figur 1 verdecktes flügelseitiges Schwenklager des Ausstellarms 5 relativ zu dem Flügel 3 stationär.The opening scissors 4 comprises an opening arm 5 which is pivotably mounted with one end on the fixed frame 2 and the other end on the wing 3. The axis of rotation on the fixed frame side and the axis of rotation of the pivot arm 5 on the wing side run parallel to one another in the vertical direction. A pivot bearing 6 on the fixed frame side of the extension arm 5 cannot be moved relative to the fixed frame 2. Accordingly, an in Figure 1 concealed wing-side pivot bearing of the extension arm 5 relative to the wing 3 stationary.

Zwischen dem festrahmenseitigen Schwenklager 6 und dem flügelseitigen Schwenklager des Ausstellarms 5 ist an den Ausstellarm 5 ein Scherenarm 7 der Ausstellschere 4 mittels eines flügelseitigen Schwenklagers 8 angelenkt. An dem gegenüberliegenden Längsende ist der Scherenarm 7 mittels eines festrahmenseitigen Schwenklagers 9 schwenkbar an dem festen Rahmen 2 gelagert. Auch eine von dem festrahmenseitigen Schwenklager 9 ausgebildete festrahmenseitige Schwenkachse 10 und eine von dem flügelseitigen Schwenklager 8 ausgebildete flügelseitige Schwenkachse 11 des Scherenarms 7 verlaufen parallel zueinander in vertikaler Richtung. Sowohl die Schwenkachsen des Ausstellarms 5 als auch die Schwenkachsen 10, 11 des Scherenarms 7 sind somit parallel zu einer in Figur 1 gestrichelt angedeuteten vertikalen Hauptebene 12 des festen Rahmens 2 ausgerichtet.Between the pivot bearing 6 on the fixed frame side and the pivot bearing on the wing side of the extension arm 5, a scissor arm 7 of the stay arm 4 is articulated to the extension arm 5 by means of a pivot bearing 8 on the wing side. At the opposite longitudinal end, the scissor arm 7 is pivotably mounted on the fixed frame 2 by means of a pivot bearing 9 on the fixed frame side. A fixed frame-side pivot axis 10 formed by the fixed frame-side pivot bearing 9 and a wing-side pivot axis 11 of the scissor arm 7 formed by the sash-side pivot bearing 8 also run parallel to one another in the vertical direction. Both the pivot axes of the extension arm 5 and the pivot axes 10, 11 of the scissor arm 7 are thus aligned parallel to a vertical main plane 12 of the fixed frame 2, indicated by dashed lines in FIG.

Das festrahmenseitige Schwenklager 6 und das flügelseitige Schwenklager des Ausstellarms 5 sind ebenso wie das flügelseitige Schwenklager 8 und das festrahmenseitige Schwenklager 9 des Scherenarms 9 herkömmlicher Bauart. Lagerachszapfen durchsetzen entsprechende Lageraugen an den gelenkig miteinander verbundenen Bauteilen.The pivot bearing 6 on the fixed frame side and the pivot bearing on the wing side of the raising arm 5, like the pivot bearing 8 on the wing side and the pivot bearing 9 on the fixed frame side of the scissor arm 9, are of conventional design. Bearing journals enforce corresponding bearing eyes on the articulated components.

Anders als das festrahmenseitige Schwenklager 6 des Ausstellarms 5 ist das festrahmenseitige Schwenklager 9 des Scherenarms 7 entlang des festen Rahmens 2 beweglich. Die Bewegungsrichtung des festrahmenseitigen Schwenklagers 9 des Scherenarms 7 ist in Figur 1 durch einen Doppelpfeil 13 veranschaulicht.Unlike the pivot bearing 6 on the fixed frame side of the extension arm 5, the pivot bearing 9 on the fixed frame side of the scissor arm 7 is movable along the fixed frame 2. The direction of movement of the pivot bearing 9 on the fixed frame side of the scissor arm 7 is shown in FIG Figure 1 illustrated by a double arrow 13.

Um Bewegungen längs des festen Rahmens 2 ausführen zu können, ist das festrahmenseitige Schwenklager 9 des Scherenarms 7 an einem Führungsstück 14 vorgesehen, das seinerseits mittels einer festrahmenseitigen Führungsnut 15 in der Bewegungsrichtung 13 des festrahmenseitigen Schwenklagers 9 geführt ist. Die Führungsnut 15 wird durch eine mit dem festen Rahmen 2 verschraubte Führungsschiene 16 begrenzt, die eine im Querschnitt C-förmige Nutwand 17 der Führungsnut 15 ausbildet. Die Führungsnut 15 besitzt einen Nutgrund 18 und eine dem Nutgrund 18 gegenüberliegende und sich in der Bewegungsrichtung 13 des Führungsstücks 14 erstreckende Nutöffnung 19. Die Nutöffnung 19 wird begrenzt durch zueinander hin weisende horizontale Schenkel 20, 21 der im Querschnitt C-förmigen Nutwand 17.In order to be able to execute movements along the fixed frame 2, the fixed frame-side pivot bearing 9 of the scissor arm 7 is provided on a guide piece 14, which in turn is guided by means of a fixed-frame-side guide groove 15 in the direction of movement 13 of the fixed frame-side pivot bearing 9. The guide groove 15 is delimited by a guide rail 16 which is screwed to the fixed frame 2 and which forms a groove wall 17 of the guide groove 15 which is C-shaped in cross section. The guide groove 15 has a groove base 18 and a groove opening 19 opposite the groove base 18 and extending in the direction of movement 13 of the guide piece 14. The groove opening 19 is delimited by facing horizontal legs 20, 21 of the groove wall 17, which is C-shaped in cross section.

Mit Abstand von dem Scherenarm 7 ist an dem Führungsstück 14 ein Lenker 22 der Ausstellschere 4 mittels eines entsprechenden Schwenklagers schwenkbar gelagert. Das gegenüberliegende Längsende des Lenkers 22 ist schwenkbeweglich an dem Flügel 3 gelagert und dabei relativ zu dem Flügel 3 ortsunveränderlich. Auch die Schwenklager des Lenkers 22 bilden parallel zueinander in vertikaler Richtung verlaufende Schwenkachsen aus. Beim Öffnen und Schließen des Flügels 3 führt der Lenker 22 in gewohnter Weise den Flügel 3 derart relativ zu dem festen Rahmen 2, dass eine Kollision eines an dem Flügel 3 vorgesehenen Flügelüberschlags mit dem festen Rahmen 2 vermieden wird.At a distance from the scissor arm 7, a link 22 of the scissors-opening 4 is pivotably mounted on the guide piece 14 by means of a corresponding pivot bearing. The opposite longitudinal end of the link 22 is pivotably mounted on the wing 3 and is immovable in position relative to the wing 3. The pivot bearings of the link 22 also form pivot axes running parallel to one another in the vertical direction. When opening and closing the sash 3, the link 22 guides the sash 3 in the usual manner relative to the fixed frame 2 in such a way that a collision of a sash rollover provided on the sash 3 with the fixed frame 2 is avoided.

Das in der festrahmenseitigen Führungsnut 15 in der Bewegungsrichtung 13 des festrahmenseitigen Schwenklagers 9 geführte Führungsstück 14 ist im Einzelnen in den Figuren 2 bis 6 dargestellt, wobei diese Abbildungen das Führungsstück 14 vor der Montage an der festrahmenseitigen Führungsnut 15 zeigen.The guide piece 14 guided in the guide groove 15 on the fixed frame side in the direction of movement 13 of the pivot bearing 9 on the fixed frame side is in detail in the Figures 2 to 6 shown, these figures showing the guide piece 14 prior to assembly on the guide groove 15 on the fixed frame side.

Bei dem Führungsstück 14 handelt es sich um ein Verbundbauteil mit einem metallenen Träger 23 und einem Kunststoffanteil 24. Der Kunststoffanteil 24 ist an den metallenen Träger 23 des Führungsstücks 14 angespritzt.The guide piece 14 is a composite component with a metal support 23 and a plastic component 24. The plastic component 24 is injection molded onto the metal support 23 of the guide piece 14.

Gemäß Figur 5 besitzt der metallene Träger 23 des Führungsstücks 14 einen im Wesentlichen hutförmigen Querschnitt. Mit geschwungenen Schenkeln 25, 26 erstreckt sich der metallene Träger 23 nahezu über die gesamte Länge des Führungsstücks 14. In etwa mittig bildet der metallene Träger 23 eine mit einem nicht gezeigten Innengewinde versehene Hülse 27 aus. Das Innengewinde der Hülse 27 nimmt ein Außengewinde an einer in den Figuren 1 und 2 erkennbaren Stellschraube 28 auf. Der Hülse 27 des metallenen Träger 23 beidseits benachbart sind Lageraugen, welche den Lagerachszapfen des festrahmenseitigen Schwenklagers 9 des Scherenarms 7 und den Lagerachszapfen des festrahmenseitigen Schwenklagers des Lenkers 22 aufnehmen.According to Figure 5 the metal carrier 23 of the guide piece 14 has a substantially hat-shaped cross section. With curved legs 25, 26, the metal support 23 extends almost over the entire length of the guide piece 14. Approximately in the middle, the metal support 23 forms a sleeve 27 provided with an internal thread (not shown). The internal thread of the sleeve 27 takes an external thread on one in the Figures 1 and 2 recognizable adjusting screw 28. The sleeve 27 of the metal carrier 23 are adjacent on both sides of the bearing eyes, which receive the bearing journal of the pivot bearing 9 of the scissor arm 7 on the fixed frame side and the journal of the pivot bearing of the link 22 on the fixed frame side.

Unterhalb der Hülse 27 ist zwischen den geschwungenen Schenkeln 25, 26 des metallenen Trägers 23 in dem Kunststoffanteil 24 des Führungsstücks 14 eine Aufnahme 29 ausgespart. Die Aufnahme 29 ist für einen als Bremselement vorgesehenen Bremsklotz 30 bestimmt. Ebenso wie bei dem Kunststoffanteil 24 des Führungsstücks 14 handelt es sich auch bei dem Bremsklotz 30 um ein Kunststoff-Spritzteil. Unter Ausbildung einer Bauteilverbindung 31 ist der Bremsklotz 30 an den Kunststoffanteil 24 des Führungsstücks 14 angespritzt.Below the sleeve 27, a receptacle 29 is cut out between the curved legs 25, 26 of the metal carrier 23 in the plastic portion 24 of the guide piece 14. The receptacle 29 is intended for a brake pad 30 provided as a braking element. As with the plastic portion 24 of the guide piece 14, the brake pad 30 is also an injection-molded plastic part. With the formation of a component connection 31, the brake pad 30 is molded onto the plastic portion 24 of the guide piece 14.

Aufgrund entsprechender Materialeigenschaften des für den Kunststoffanteil 24 des Führungsstücks 14, den Bremsklotz 30 und die Bauteilverbindung 31 verwendeten Kunststoffs lässt die Bauteilverbindung 31 Schwenkbewegungen des Bremsklotzes 30 relativ zu dem Führungsstück 14 in Richtung eines in Figur 4 dargestellten Doppelpfeils 32 zu. An dem Ansatz der Bauteilverbindung 31 an dem Kunststoffanteil 24 des Führungsstücks 14 ist eine in Figur 4 senkrecht zu der Zeichenebene verlaufende Schwenkachse 33 des Bremsklotzes 30 ausgebildet. Der Bremsklotz 30 ist Teil einer einstellbaren Friktionsbremse 34 für das Führungsstück 14 und somit für den Flügel 3 des Fensters 1.Due to corresponding material properties of the plastic used for the plastic portion 24 of the guide piece 14, the brake pad 30 and the component connection 31, the component connection 31 allows pivoting movements of the brake pad 30 relative to the guide piece 14 in the direction of an in Figure 4 shown double arrow 32 to. At the approach of the component connection 31 on the plastic portion 24 of the guide piece 14 is an in Figure 4 Pivot axis 33 of brake pad 30 running perpendicular to the plane of the drawing is formed. The brake pad 30 is part of an adjustable friction brake 34 for the guide piece 14 and thus for the sash 3 of the window 1.

Bei der Montage an der festrahmenseitigen Führungsschiene 16 ist das Führungsstück 14 in einer senkrecht zu der Schwenkachse 33 des Bremsklotzes 30 verlaufenden Einschubrichtung 35 in die festrahmenseitige Führungsnut 15 einzuschieben. Dabei ist das Führungsstück 14 derart auszurichten, dass die an der Unterseite des Führungsstücks 14 vorgesehene Aufnahme 29 für den Bremsklotz 30 bei der Montagebewegung gegenüber der zwischen dem Führungsstück 14 und dem Bremsklotz 30 vorgesehenen Bauteilverbindung 31 in der Einschubrichtung 35 nacheilt. Zur Vermeidung einer Fehlausrichtung des Führungsstücks 14 bei der Montage ist in den Kunststoffanteil 24 des Führungsstücks 14 an dessen Oberseite ein die Einschubrichtung 35 symbolisierender Pfeil eingeformt (Figur 2).During assembly on the guide rail 16 on the fixed frame side, the guide piece 14 is to be pushed into the guide groove 15 on the fixed frame side in an insertion direction 35 running perpendicular to the pivot axis 33 of the brake pad 30. The guide piece 14 is to be aligned in such a way that the receptacle 29 for the brake pad 30 provided on the underside of the guide piece 14 lags in the insertion direction 35 during the assembly movement compared to the component connection 31 provided between the guide piece 14 and the brake pad 30. To avoid misalignment of the guide piece 14 during assembly, an arrow symbolizing the direction of insertion 35 is molded into the plastic part 24 of the guide piece 14 on its upper side ( Figure 2 ).

Zum Einführen in die Führungsnut 15 ist das Führungsstück 14 an der Führungsnut 15 derart anzusetzen, dass bei einer Bewegung des Führungsstücks 14 in der Einschubrichtung 35 die Schenkel 20, 21 der Nutwand 17 der Führungsnut 15 in Längsnuten 36, 37 einlaufen, die sich an dem Kunststoffanteil 24 des Führungsstücks 14 über dessen gesamte Länge erstrecken und die in Querrichtung des Führungsstücks 14 bis über die geschwungenen Schenkel 25, 26 des metallenen Trägers 23 des Führungsstücks 14 reichen (Figur 5).For insertion into the guide groove 15, the guide piece 14 is to be placed on the guide groove 15 in such a way that when the guide piece 14 moves in the insertion direction 35, the legs 20, 21 of the groove wall 17 of the guide groove 15 run into longitudinal grooves 36, 37 which are located on the Plastic part 24 of the guide piece 14 extend over its entire length and extend in the transverse direction of the guide piece 14 to over the curved legs 25, 26 of the metal carrier 23 of the guide piece 14 ( Figure 5 ).

Im Ausgangszustand außerhalb der Führungsnut 15 besitzen das Führungsstück 14 und der mittels der Bauteilverbindung 31 an dem Führungsstück 14 gehaltene Bremsklotz 30 einen gemeinschaftlichen Querschnitt, der in der senkrechten Projektion in der Einschubrichtung 35 auf den Querschnitt der Führungsnut 15 den Querschnitt der Führungsnut 15 überragt, da der Bremsklotz 30 einen Überstand gegenüber dem Führungsstück 14 ausbildet. Um den Überstand des Bremsklotzes 30 gegenüber dem Führungsstück 14 zu beseitigen und dadurch den gemeinschaftlichen Querschnitt des Führungsstücks 14 und des Bremsklotzes 30 derart zu reduzieren, dass er innerhalb des Querschnitts der festrahmenseitigen Führungsnut 15 liegt, ist der Bremsklotz 30 aus der Position gemäß den Figuren 2, 4 und 6 um die Schwenkachse 33 gegen das Führungsstück 14 zu schwenken, bis der Bremsklotz 30 im Inneren der Aufnahme 29 an dem Führungsstück 14 zu liegen kommt. Ist der Bremsklotz 30 in die Aufnahme 29 an dem Führungsstück 14 eingeschwenkt, so kann das Führungsstück 14 über seine gesamte Länge in der Einschubrichtung 35 in die Führungsnut 15 eingeführt werden.In the initial state outside the guide groove 15, the guide piece 14 and the brake pad 30 held on the guide piece 14 by means of the component connection 31 have a common cross-section which, in the vertical projection in the insertion direction 35 onto the cross-section of the guide groove 15, projects beyond the cross-section of the guide groove 15, since the brake pad 30 forms a protrusion relative to the guide piece 14. In order to eliminate the protrusion of the brake pad 30 relative to the guide piece 14 and thereby reduce the common cross section of the guide piece 14 and the brake pad 30 such that it lies within the cross section of the guide groove 15 on the fixed frame side, the brake pad 30 is out of the position according to FIGS Figures 2 , 4 and 6 to pivot about the pivot axis 33 against the guide piece 14 until the brake pad 30 comes to rest on the guide piece 14 inside the receptacle 29. If the brake pad 30 is pivoted into the receptacle 29 on the guide piece 14, the guide piece 14 can be inserted into the guide groove 15 over its entire length in the insertion direction 35.

Der Monteur kann den Bremsklotz 30 mit einem entsprechenden Handgriff in die Aufnahme 29 an dem Führungsstück 14 einschwenken und anschließend das Führungsstück 14 gemeinsam mit dem Bremsklotz 30 vollständig in die Führungsnut 15 einschieben. Verzichtet der Monteur bewusst oder versehentlich auf das Einschwenken des Bremsklotzes 30 in die Aufnahme 29 an dem Führungsstück 14, so läuft beim Einschieben des Führungsstücks 14 in die Führungsnut 15 in der Einschubrichtung 35 die Bauteilverbindung 31 auf die Stirnfläche der Nutwand 17 der Führungsnut 15 auf und eine fortgesetzte Bewegung des Führungsstücks 14 in der Einschubrichtung 35 bewirkt, dass der Bremsklotz 30 selbsttätig und ohne Gefahr zu laufen, gewaltsam von dem Führungsstück getrennt zu werden, aus der Position gemäß Figur 4 in Richtung auf die Aufnahme 29 ausgelenkt wird und schließlich in die Aufnahme 29 an dem Führungsstück 14 eintaucht. Damit nimmt der Bremsklotz 30 dann eine Position ein, bei welcher der gemeinschaftliche Querschnitt des Führungsstücks 14 und des Bremsklotzes 30 innerhalb des Querschnitts der Führungsnut 15 liegt und bei welcher folglich ein vollständiges Einführen des Führungsstücks 14 in die Führungsnut 15 möglich ist.The fitter can swivel the brake pad 30 into the receptacle 29 on the guide piece 14 with a corresponding handle and then slide the guide piece 14 together with the brake pad 30 completely into the guide groove 15. If the fitter deliberately or inadvertently does not swivel the brake pad 30 into the receptacle 29 on the guide piece 14, when the guide piece 14 is pushed into the guide groove 15 in the insertion direction 35, the component connection 31 runs onto the end face of the groove wall 17 of the guide groove 15 and a continued movement of the guide piece 14 in the insertion direction 35 has the effect that the brake pad 30 automatically and without running the risk of being forcibly separated from the guide piece, from the position according to FIG Figure 4 is deflected in the direction of the receptacle 29 and finally dips into the receptacle 29 on the guide piece 14. Thus, the brake pad 30 then assumes a position in which the common cross section of the guide piece 14 and the brake pad 30 within of the cross section of the guide groove 15 and in which consequently a complete insertion of the guide piece 14 into the guide groove 15 is possible.

Genutzt wird der Bremsklotz 30 dazu, für die mit einer Öffnungs- oder einer Schließbewegung des Flügels 3 verbundene Bewegung des an der Führungsnut 15 montierten Führungsstücks 14 und des an diesem vorgesehenen festrahmenseitigen Schwenklagers 9 entlang des festen Rahmens 2 einen Bewegungswiderstand zu erzeugen, aufgrund dessen der Flügel 3 eine momentane Schwenkstellung nur dann verlässt, wenn auf den Flügel 3 eine hinreichend große Kraft in Öffnungs- oder Schließrichtung wirkt.The brake pad 30 is used to generate a movement resistance for the movement of the guide piece 14 mounted on the guide groove 15 and the pivot bearing 9 on the fixed frame side along the fixed frame 2 associated with an opening or closing movement of the sash 3, due to which the Wing 3 leaves a momentary pivoting position only when a sufficiently large force acts on the wing 3 in the opening or closing direction.

Zur Regulierung des mittels des Bremsklotzes 30 erzeugten Bewegungswiderstandes dient die Stellschraube 28, die mit ihrem Außengewinde in das Innengewinde an der Hülse 27 des metallenen Trägers 23 des Führungsstücks 14 eingreift. Durch entsprechende Drehbetätigung der Stellschraube 28 kann der Bremsklotz 30 zwischen dem Nutgrund 18 der festrahmenseitigen Führungsnut 15 und dem von den Schenkeln 20, 21 der Nutwand 17 parallel zu dem Nutgrund 18 übergriffenen Führungsstück 14 mehr oder weniger stark eingespannt werden. Kräfte die infolge des Einspannens des Bremsklotzes 30 zwischen dem Führungsstück 14 und dem Nutgrund 18 der Führungsnut 15 auftreten, werden über das Führungsstück 14 und die Nutwand 17 der Führungsnut 15 in den festen Rahmen 2 abgetragen. Dabei ist es von Vorteil, dass der hinreichend lastaufnahmefähige metallene Träger 23 des Führungsstücks 14 in den Kraftfluss einbezogen ist. Eine unerwünschte Deformierung des Führungsstücks 14 unter der Wirkung der auftretenden Kräfte wird dadurch verhindert.The adjusting screw 28, which engages with its external thread in the internal thread on the sleeve 27 of the metal carrier 23 of the guide piece 14, is used to regulate the resistance to movement generated by the brake pad 30. By appropriately turning the adjusting screw 28, the brake pad 30 can be clamped to a greater or lesser extent between the groove base 18 of the guide groove 15 on the fixed frame side and the guide piece 14 overlapped by the legs 20, 21 of the groove wall 17 parallel to the groove base 18. Forces that occur between the guide piece 14 and the groove base 18 of the guide groove 15 as a result of the clamping of the brake pad 30 are carried away into the fixed frame 2 via the guide piece 14 and the groove wall 17 of the guide groove 15. It is advantageous that the metal carrier 23 of the guide piece 14, which is sufficiently load-bearing, is included in the force flow. An undesired deformation of the guide piece 14 under the effect of the forces that occur is prevented.
