Abstract

One, or more extension arms (1) hinge on parallel axes (3) on the frame and the leaf of the door or window. One of the arm bearings is on a slide travelling (9) in the direction of the plane (19) of the leaf or frame along a guide bar (8), while a transverse protrusion (11) on the slide (2) engages behind the bar. The bar contains a continuous recess (10) running in the direction of the plane of the frame or leaf. The transverse dimension of the recess matches that of the protrusion, which is accommodated in the recess during installation of the arm, when the latter is in a position different from its working positions. A stop can be provided on the leaf or frame limiting the opening movement of the slide, which tilts on an eccentric axis in relation to the arm and works between two bars spaced apart, each of which contains a recess.

Disassembly of the slider requires in the case of the prior art, disassembly of the casement or an at least partial removal of the profile groove delimiting crossbars.

Eine gattungsgemäße Ausstellvorrichtung ist in GB 246,071 A offenbart. Ein Ausstellarm ist dabei mit einem Ende an einem festen Türrahmen angelenkt und an dem gegenüberliegenden Ende mit einem Schiebestück in Form eines Gleiters versehen. Der Gleiter ist drehbar an dem Ausstellarm gelagert und in eingebautem Zustand an dem oberen Querholm eines Türflügels in Holmlängsrichtung verschiebbar geführt. Zur Führung des Gleiters dient eine flügelfeste Führungsplatte mit einem sich in Verschieberichtung des Gleiters erstreckenden Führungsschlitz. Mit den Rändern des Führungsschlitzes befindet sich der Gleiter an entsprechenden Nuten im Eingriff. An einem Ende des Führungsschlitzes sind dessen Ränder ausgespart. Dadurch ergibt sich in der Führungsplatte eine Öffnung, durch welche der Gleiter senkrecht zu der Führungsplatte in diese eingesetzt werden kann. Anschließend läßt sich der Gleiter durch Bewegung in Längsrichtung des Führungsschlitzes mit seinen Nuten auf die Ränder des Führungsschlitzes aufschieben.A generic display device is disclosed in GB 246,071 A. An extension arm is fixed to one end Door frame hinged and at the opposite end with a Provide sliding piece in the form of a glider. The glider is rotatably mounted on the extension arm and in the installed state the upper cross member of a door leaf in the longitudinal direction of the bar guided. A wing-fixed is used to guide the glider Guide plate with a slide in the direction of displacement extending guide slot. With the edges of the guide slot the glider is located on the corresponding grooves in the Intervention. At one end of the guide slot are its edges spared.

Montage und Demontage einer Ausstellvorrichtung zu vereinfachen, hat sich die vorliegende Erfindung zum Ziel gesetzt.To simplify assembly and disassembly of a display device, the present invention has set itself the goal.

Erfindungsgemäß gelöst wird diese Aufgabe durch die Ausstellvorrichtung gemäß Patentanspruch 1 sowie durch die Ausstellvorrichtung gemäß Patentanspruch 2. Aufgrund der anspruchsgemäßen Gestaltung der Führungsleiste(n) kann das Schiebestück mit seinem Führungsvorsprung bzw. mit seinen Führungsvorsprüngen die zugehörige(n) Führungsleiste(n) senkrecht zu der Verschieberichtung passieren und anschließend durch Verschieben in Verschieberichtung mit der betreffenden Führungsleiste in Hintergriff gebracht werden. Zur Demontage ist das Schiebestück entlang der Führungsleiste bzw. der Führungsleisten so weit zu bewegen, bis sein Führungsvorsprung bzw. seine Führungsvorsprünge innerhalb der Kontur der betreffenden Ausnehmung an der Führungsleiste bzw. den Führungsleisten zu liegen kommt bzw. kommen. Bei dieser Relativlage von Schiebestück und Führungsleiste(n) läßt sich ersteres senkrecht zu der Verschieberichtung durch die Ausnehmung bzw. die Ausnehmungen der Führungsleiste(n) von dem festen Rahmen bzw. von dem Flügel abheben. Ein unbeabsichtigtes Lösen der Formschlußverbindung zwischen Schiebestück und festem Rahmen bzw. Flügel bei bestimmungsgemäßen Betrieb der Ausstellvorrichtung wird dadurch vermieden, daß das Schiebestück eine seine Montage oder seine Demontage erlaubende Stellung nur dann einnehmen kann, wenn sich der Ausstellarm nicht in einer seiner Betriebsstellungen befindet.According to the invention, this object is achieved by the opening device according to claim 1 and by the display device according to claim 2. Due to the sophisticated design the guide bar (s) can the sliding piece with his Leadership lead or, with its leadership ledges, the associated lead (s) Guide bar (s) perpendicular to the direction of displacement pass and then by moving in the direction of movement brought into engagement with the relevant guide bar become. The sliding piece along the guide bar is for disassembly or to move the guide rails until its guide projection or its lead projections within the contour the recess in question on the guide bar or the guide bars comes to rest. With this relative position the sliding piece and guide rail (s) can be vertical to the direction of displacement through the recess or Recesses of the guide bar (s) from the fixed frame or take off the wing. An unintentional loosening of the positive connection between sliding piece and fixed frame or sash proper operation of the display device avoided that the sliding piece one its assembly or disassembly can only take a permissive position if the extension arm is not in one of its operating positions.

Eine besondere Handhabungsfreundlichkeit bei der Montage bedingt der gemäß Patentanspruch 1 an dem festen Rahmen bzw. an dem Flügel vorgesehene Montageanschlag, an welchem sich das Schiebestück bei Montagestellung des Ausstellarms über einen Gegenanschlag in Verschieberichtung abstützt. Bei der Montage der Ausstellvorrichtung ist das Schiebestück zunächst in Verschieberichtung an dem Montageanschlag zur Anlage zu bringen. In der dann eingenommenen Position liegt das Schiebestück mit seinem Führungsvorsprung bzw. mit seinen Führungsvorsprüngen innerhalb der Kontur der zugeordneten Ausnehmung(en) an der (den) Führungsleiste(n). Dementsprechend markiert der Montageanschlag für den Monteur diejenige Lage des Schiebestücks, in welcher sich dieses mit der oder den Führungsleisten an dem festen Rahmen bzw. an dem Flügel formschlüssig verbinden läßt. Die Flanken des Keilausschnitts bewirken im Zusammenspiel mit dem ortsfesten Anschlagzapfen eine selbsttätige Ausrichtung des an den Anschlagzapfen geschobenen Schiebestücks in eine Stellung, in welcher der oder die Führungsvorsprünge des Schiebestücks im Innern der Kontur der zugeordneten Ausnehmung(en) an der Führungsleiste liegen. A particular ease of use during assembly requires the according to claim 1 on the fixed frame or on the wing provided mounting stop on which the sliding piece when the extension arm is in the assembly position via a counter stop in Supported displacement direction. When installing the display device is the sliding piece on the Bring the assembly stop to the system. In the then taken Position is the sliding piece with its guide projection or with its lead projections within the contour of the assigned Cutout (s) on the guide bar (s). Accordingly the assembly stop marks the position for the fitter of the sliding piece, in which this is with the or the guide strips on the fixed frame or wing lets connect. The flanks of the wedge cutout result in Interaction with the fixed stop pin an automatic Alignment of the sliding piece pushed onto the stop pin in a position in which the guide projection (s) of the Sliding piece inside the contour of the assigned recess (s) lie on the guide bar.

Die gemäß Patentanspruch 2 vorgesehenen Überstände der Schenkel an dem Schiebestück flankieren bei der Montage des Schiebestücks die Führungsleisten in Querrichtung der Rahmen- bzw. der Flügelhauptebene und sorgen dadurch für eine Führung des Schiebestücks.The projections of the legs provided according to claim 2 flank on the sliding piece when mounting the sliding piece the guide strips in the transverse direction of the frame or wing main plane and thus ensure that the sliding piece is guided.

Eine besondere Bedeutung kommt einer einfachen Montage und Demontage bei Ausstellvorrichtungen der vorstehend beschriebenen Art zu, im Falle derer an dem festen Rahmen und/oder an dem Flügel wenigstens ein Öffnungsbegrenzungsanschlag vorgesehen ist, an welchem das Schiebestück bei maximaler Ausstellweite des Flügels in seiner der Ausstellbewegung des Flügels zugeordneten Bewegungsrichtung abgestützt ist und das Schiebestück um eine in Verschieberichtung außermittige sowie in Richtung der Rahmen- bzw. der Flügelhauptebene verlaufende Drehachse gegenüber dem Ausstellarm schwenkbar mit diesem verbunden ist und im Falle derer die Schiebeführung des Schiebestücks wenigstens zwei in Querrichtung der Rahmen- bzw. der Flügelhauptebene voneinander beabstandete Führungsleisten aufweist. Ist jede der Führungsleisten einer derartigen Ausstellvorrichtung mit wenigstens einer in Richtung der Rahmen- bzw. der Flügelhauptebene durchgängigen Ausnehmung versehen, so läßt sich die eingestellte maximale Ausstellweite des Flügels auf äußerst einfache Art und Weise variieren. Das an dem festen Rahmen bzw. an dem Flügel geführte Schiebestück kann dann nämlich in der vorstehend beschriebenen Weise mit wenigen Handgriffen zunächst von dem festen Rahmen bzw. dem Flügel gelöst werden. Anschließend läßt sich das Schiebestück gegenüber dem Ausstellarm beispielsweise um 180° drehen und in dieser geänderten Lage erneut mit seinem Führungsvorsprung bzw. mit seinen Führungsvorsprüngen in Hintergriff mit der zugehörigen Führungsleiste bzw. den zugehörigen Führungsleisten bringen. Aufgrund der in Verschieberichtung außermittigen Anordnung der Drehachse des Schiebestücks sowie aufgrund der ortsfesten Anordnung des Öffnungsbegrenzungsanschlages geht die beschriebene Verstellung des Schiebestücks einher mit einer Veränderung der maximalen Ausstellweite des Flügels.Easy assembly and disassembly is of particular importance with display devices of the type described above to, in the case of those on the fixed frame and / or on the wing at least one opening limit stop is provided which the sliding piece with the maximum opening width of the wing in its direction of movement associated with the opening movement of the wing is supported and the sliding piece by one in the direction of displacement off-center as well as in the direction of the frame or the main axis of rotation is the axis of rotation opposite the extension arm is pivotally connected to this and in the case of which the Sliding guide of the sliding piece at least two in the transverse direction the frame or wing main plane spaced apart Has guide rails. Is each of the guide rails one of such Display device with at least one in the direction of Provide a recess in the frame or the main wing plane, the set maximum opening width of the Wing vary in a very simple way. That about that fixed frame or sliding piece guided on the wing can then namely in the manner described above with a few simple steps first detached from the fixed frame or sash become. Then the sliding piece can be compared to the For example, turn the extension arm by 180 ° and change it in this Situation again with its lead or with its lead in engagement with the associated guide bar or bring the associated guide rails. Due to the in Direction of displacement off-center arrangement of the axis of rotation of the Sliding piece and due to the fixed arrangement of the opening limit stop goes the described adjustment of Sliding pieces accompanied by a change in the maximum opening width of the wing.

Die Vorteile, die im Falle einer Ausstellvorrichtung nach Patentanspruch 2 mit den kennzeichnenden Merkmalen der Patentansprüche 3 und 4 verbunden sind, ergeben sich in analoger Weise aus den vorstehenden Ausführungen zu Patentanspruch 1.The advantages in the case of a display device according to claim 2 with the characterizing features of the claims 3 and 4 are connected, result in an analogous manner from the The above statements on claim 1.

Im Falle von Ausstellvorrichtungen, deren Schiebestück um eine in Richtung der Rahmen- bzw. der Flügelhauptebene verlaufende Drehachse relativ zu dem Ausstellarm schwenkbar mit diesem verbunden ist, ist in Weiterbildung der Erfindung vorgesehen, daß das Schiebestück an dem Ausstellarm in Richtung seiner Drehachse über ein Reibschlußelement in Richtung seiner Schwenkbewegung gegenüber dem Ausstellarm reibschlüssig lösbar abgestützt ist. Die freie Schwenkbeweglichkeit des Schiebestücks gegenüber dem Ausstellarm wird mittels des genannten Reibschlußelementes im Interesse einer vereinfachten Montage eingeschränkt. So behält das Schiebestück aufgrund des wirksamen Reibschlusses eine einmal vorgenommene und für die Montage zweckmäßige Ausrichtung gegenüber dem Ausstellarm vorläufig bei.In the case of display devices, the sliding piece by one in Direction of rotation of the frame or wing main plane pivotally connected to the extension arm is provided in a development of the invention that Sliding piece on the extension arm in the direction of its axis of rotation a frictional element in the direction of its pivotal movement the extension arm is frictionally releasably supported. The free swivel movement of the sliding piece in relation to the extension arm becomes in the interest by means of the mentioned frictional engagement element a simplified installation. So keep that Sliding piece once due to the effective frictional connection made and suitable for assembly opposite alignment the extension arm for the time being.

Mit konstruktiv einfachsten Mitteln wird der lösbare Reibschluß zwischen Schiebestück und Ausstellarm im Falle einer Ausführungsform der erfindungsgemäßen Ausstellvorrichtung dadurch erzeugt, daß als Reibschlußelement ein die Drehachse des Schiebestücks umschließender und zwischen dem Schiebestück und dem Ausstellarm in Richtung der genannten Drehachse geklemmter Gummiring vorgesehen ist.The releasable frictional engagement is achieved with the simplest design means between sliding piece and extension arm in the case of one embodiment the display device according to the invention generated by that as a frictional element enclosing the axis of rotation of the sliding piece and between the sliding piece and the extension arm in Provided clamped rubber ring in the direction of said axis of rotation is.

Gemäß Figur 1 umfaßt eine Ausstellvorrichtung für einen in Figur 1 gestrichelt angedeuteten Fensterflügel einen Ausstellarm 1, an dessen einem Ende ein Schiebestück 2 angelenkt ist. Mit seinem anderen Ende ist der Ausstellarm 1 an einem festen Fensterrahmen schwenkbar gelagert. Die rahmenseitige Schwenkachse des Ausstellarms 1 verläuft parallel zu einer Achse 3, die eine Schwenkverbindung zwischen dem Ausstellarm 1 und dem Fensterflügel herstellt.According to Figure 1 comprises an opening device for one in Figure 1 window sash indicated by dashed lines an opening arm 1 one end of which is articulated a sliding piece 2. With his the other end is the extension arm 1 on a fixed window frame pivoted. The swivel axis of the extension arm on the frame 1 runs parallel to an axis 3, which is a pivot connection between the opening arm 1 and the window sash.

Die Achse 3 des Ausstellarms 1 bildet gleichzeitig eine Drehachse des Schiebestücks 2, um welche letzteres relativ zu dem Ausstellarm 1 verschwenkt werden kann. Zwischen seinem flügelseitigen sowie seinem rahmenseitigen Ende weist der Ausstellarm 1 ein Lagerauge 4 auf.The axis 3 of the extension arm 1 also forms an axis of rotation of the sliding piece 2, by which the latter relative to the extension arm 1 can be pivoted. Between its wing-side as well The opening arm 1 has a bearing eye at its frame-side end 4 on.

Flügelseitig ist dem Ausstellarm 1 bzw. dem daran angebrachten Schiebestück 2 eine Stulpschiene 5 zugeordnet, die im Falz des oberen Fensterflügel-Querholms mit letzterem verschraubt wird. Die betreffenden Befestigungsschrauben werden durch Befestigungsbohrungen 6 der Stulpschiene 5 in den Fensterflügel eingedreht.On the wing side is the extension arm 1 or the one attached to it Sliding piece 2 is assigned a faceplate 5, which in the fold of upper window casement cross member is screwed to the latter. The mounting screws in question are through mounting holes 6 of the faceplate 5 screwed into the window sash.

In einem beispielsweise aus Figur 3 ersichtlichen abgekröpften Bereich 7 der Stulpschiene 5 bilden deren Längsränder 8 Führungsleisten zur Führung des Schiebestücks 2 in durch einen Doppelpfeil 9 veranschaulichter Verschieberichtung. Die Längsränder bzw. Führungsleisten 8 an der Stulpschiene 5 sind mit insgesamt vier einander paarweise gegenüberliegenden Ausnehmungen 10 versehen.In a cranked one, for example shown in FIG Area 7 of the faceplate 5 form its longitudinal edges 8 guide strips to guide the sliding piece 2 in by a double arrow 9 illustrated direction of displacement. The longitudinal edges or guide strips 8 on the faceplate 5 are with a total four mutually opposite recesses 10 provided.

Das Schiebestück 2 weist vier einander paarweise gegenüberliegende Führungsvorsprünge 11 auf. Diese stehen gemäß Figur 4 von Schenkeln 12 des im Querschnitt U-förmigen Schiebestücks 2 vor. Ebenfalls in Figur 4 dargestellt ist ein Gummiring 13, der zwischen dem Schiebestück 2 und dem Ausstellarm 1 in Richtung der Drehachse bzw. Achse 3 geklemmt ist. Wie aus Figur 4 des weiteren hervorgeht, sind die Schenkel 12 des Schiebestücks 2 unter Ausbildung jeweils eines Überstandes 20 über die Führungsvorsprünge 11 hinaus verlängert. An ihren einander zugewandten Seiten sind die Überstände 20 mit Schrägflächen 21 versehen. In einen die Schenkel 12 miteinander verbindenden Quersteg 22 des Schiebestücks 12, ist eine Wellenform 23 eingeformt. Die Stulpschiene 5 ist in ihrem abgekröpften Bereich 7 mit zwei in Verschieberichtung 9 voneinander beabstandeten wellenförmigen Erhebungen 24 versehen. Öffnungsbegrenzungsanschläge 25 der Stulpschiene 5 in Form von Vorsprüngen quer zu der Verschieberichtung 9 begrenzen die Führungsleisten 8 des Schiebestücks 2 in Richtung auf die Anlenkstelle eines Zusatzarms 17.The sliding piece 2 has four opposing pairs Guide projections 11 on. According to FIG. 4 of Legs 12 of the U-shaped sliding piece 2 in front. Also shown in Figure 4 is a rubber ring 13 which between the sliding piece 2 and the extension arm 1 in the direction of Axis of rotation or axis 3 is clamped. As from Figure 4 further emerges, the legs 12 of the sliding piece 2 are under training one overhang 20 each over the guide projections 11 extended. Are on their mutually facing sides the projections 20 are provided with inclined surfaces 21. In a die Leg 12 connecting transverse web 22 of the sliding piece 12, a waveform 23 is molded. The faceplate 5 is in its cranked area 7 with two in the direction of displacement 9 spaced apart undulating elevations 24 Mistake. Opening limit stops 25 of the faceplate 5 in Limit the shape of projections transverse to the direction of displacement 9 the guide strips 8 of the sliding piece 2 in the direction of the articulation point an additional arm 17.

An beiden Stirnseiten ist das Schiebestück 2 mit einem Keilausschnitt 14 versehen, der jeweils von zwei Flanken 15 begrenzt wird. An der Stulpschiene 5 ist den Keilausschnitten 14 des Schiebestücks 2 ein Montageanschlag in Form eines Anschlagzapfens 16 zugeordnet. Mit Abstand von dem Anschlagzapfen 16 in Verschieberichtung 9 ist an der Stulpschiene 5 der Zusatzarm 17 angelenkt, der an seinem von der Stulpschiene 5 abliegenden Ende einen Lagerzapfen 18 trägt. Eine Flügelhauptebene 19 ist in den Figuren 1 und 4 angedeutet.The sliding piece 2 with a wedge cut-out is on both ends 14 provided, each delimited by two flanks 15 becomes. On the faceplate 5 is the wedge cutouts 14 of the Sliding piece 2 an assembly stop in the form of a stop pin 16 assigned. At a distance from the stop pin 16 in the direction of displacement 9, the additional arm 17 is articulated on the faceplate 5, the end remote from the faceplate 5 carries a journal 18. A main wing level 19 is in the Figures 1 and 4 indicated.

Vor der Montage des Ausstellarms 1 mit dem daran vormontierten Schiebestück 2 ist die Stulpschiene 5 mit den zugehörigen Anbauteilen bereits über die vorstehend erwähnten Schraubverbindungen an dem Fensterflügel fixiert. Soll nun der Ausstellarm 1 an dem Flügel angelenkt werden, so wird zunächst das mit dem Ausstellarm 1 schwenkbar verbundene Schiebestück 2 senkrecht zu dem Falz des Flügels in dem abgekröpften Bereich 7 auf die Stulpschiene 5 aufgesetzt. Anschließend wird das Schiebestück 2 in Verschieberichtung 9 verschoben, bis es mit seinem voreilenden Ende bzw. den Flanken 15 des daran vorgesehenen Keilausschnitts 14 an dem Anschlagzapfen 16 zur Anlage kommt. Gemäß Figur 1 ist das Schiebestück 2 mit seiner Längsachse unter einem spitzen Winkel gegen die Flügelhauptebene 19 geneigt angeordnet. Ausgehend von dieser Lage wird das Schiebestück 2 unter Abstützung der Flanken 15 seines Keilausschnitts 14 an dem Anschlagzapfen 16 um diesen so weit in Figur 1 im Gegenuhrzeigersinn verschwenkt, bis die Längsachse des Schiebestücks 2 in Richtung der Flügelhauptebene 19 verläuft. Before installing the extension arm 1 with the preassembled one Sliding piece 2 is the faceplate 5 with the associated attachments already on the screw connections mentioned above fixed to the window sash. If the extension arm 1 on the Wings are articulated, so that is with the extension arm 1 pivotally connected sliding piece 2 perpendicular to the fold of the Wing placed in the cranked area 7 on the faceplate 5. Then the sliding piece 2 in the direction of displacement 9 moved until it with its leading end or the Flanks 15 of the wedge cutout 14 provided thereon on the stop pin 16 comes to the plant. According to Figure 1, the sliding piece 2 with its longitudinal axis at an acute angle the main wing plane 19 arranged inclined. Starting from this Position, the sliding piece 2 is supported by the flanks 15 of his Wedge cutout 14 on the stop pin 16 so far in Figure 1 pivoted counterclockwise until the longitudinal axis of the sliding piece 2 runs in the direction of the main wing plane 19.

Wird das Schiebestück 2 bereits mit paralleler Ausrichtung gegenüber der Flügelhauptebene 19 auf den abgekröpften Bereich 7 der Stulpschiene 5 aufgesetzt, so stützt sich das Schiebestück 2 zunächst mit seinen Führungsvorsprüngen 11 auf den Führungsleisten 8 der Stulpschiene 5 aufliegend ab. Die Überstände 20 der Schenkel 12 an dem Schiebestück 2 flankieren dabei die Führungsleisten 8 in Querrichtung der Rahmenhauptebene 19 und bewirken dadurch eine Führung des Schiebestücks 2 bei dessen Verschiebebewegung in Richtung auf den Anschlagzapfen 16. Das anfängliche Aufsetzen des Schiebestücks 2 auf den abgekröpften Bereich 7 der Stulpschiene 5 wird erleichtert durch die Schrägflächen 21 an den Überständen 20 der Schiebestück-Schenkel 12.The sliding piece 2 is already facing with a parallel orientation the wing main plane 19 on the cranked area 7 of the Forend rail 5 is placed, the sliding piece 2 is initially supported with its guide projections 11 on the guide rails 8 of the faceplate 5 from lying on. The protrusions 20 of the legs 12 on the sliding piece 2 flank the guide strips 8 in the transverse direction of the main frame level 19 and thereby effect a guide of the sliding piece 2 in its displacement movement in Direction on the stop pin 16. The initial placement of the Sliding piece 2 onto the cranked area 7 of the faceplate 5 is facilitated by the inclined surfaces 21 on the protrusions 20 the sliding piece leg 12.

In beiden beschriebenen Fällen wird die Handhabung der miteinander zu verbindenden Bauteile durch die mittels des Gummirings 13 erreichte Drehhemmung des Schiebestücks 2 gegenüber dem Ausstellarm 1 vereinfacht. Ein unkontrolliertes Verschwenken des Schiebestücks 2 wird durch die genannte Drehhemmung verhindert.In both cases described, the handling of each other components to be connected by means of the rubber ring 13 reached rotation resistance of the sliding piece 2 relative to the extension arm 1 simplified. An uncontrolled swiveling of the sliding piece 2 is prevented by the rotation inhibition mentioned.

Stützt sich das Schiebestück 2 an dem Anschlagzapfen 16 ab, so liegen die Führungsvorsprünge 11 an dem Schiebestück 2 innerhalb der Konturen der zugeordneten und in Richtung der Flügelhauptebene 19 durchgängigen Ausnehmungen 10 der Führungsleisten 8 an der Stulpschiene 5. Infolgedessen läßt sich das Schiebestück 2 senkrecht zu der Stulpschiene 5 auf diese aufdrücken, bis die Führungsvorsprünge 11 des Schiebestücks 2 senkrecht zu der Stulpschiene 5 deren Führungsleisten 8 passiert haben und unterhalb der Führungsleisten 8 zu liegen kommen, wie dies in Figur 4 dargestellt ist. Nunmehr läßt sich das Schiebestück 2 und mit diesem der Ausstellarm 1 in Figur 1 nach rechts verschieben, bis das Schiebestück 2 mit seinen Führungsvorsprüngen 11 die Führungsleisten 8 an der Stulpschiene 5 hintergreift. Dadurch ergibt sich zwischen dem Schiebestück 2 und der Stulpschiene 5 eine senkrecht zu der Falzfläche des Flügels wirksame formschlüssige Verbindung, über welche der Ausstellarm 1 in entsprechender Richtung an dem Flügel festgelegt ist.The sliding piece 2 is supported on the stop pin 16, so are the guide projections 11 on the sliding piece 2 within the contours of the assigned and in the direction of the main wing plane 19 continuous recesses 10 of the guide strips 8 on the Face plate 5. As a result, the sliding piece 2 can be vertical press on the faceplate 5 until the guide projections 11 of the sliding piece 2 perpendicular to the faceplate 5 whose guide rails 8 have passed and below the guide strips 8 come to rest, as shown in Figure 4 is. Now the sliding piece 2 and with this move the extension arm 1 in Figure 1 to the right until that Sliding piece 2 with its guide projections 11, the guide strips 8 engages behind the faceplate 5. This results in a vertical between the sliding piece 2 and the faceplate 5 effective positive connection to the rebate surface of the wing, via which the extension arm 1 in the corresponding direction on the Wing is set.

Bei der beschriebenen Verschiebung des Ausstellarms 1 in Figur 1 nach rechts gelangt das Lagerauge 4 des Ausstellarms 1 in eine Stellung, in welcher der Lagerzapfen 18 des Zusatzarms 17 nach Verschwenken des Zusatzarms 17 aus seiner in Figur 1 dargestellten Ausgangslage in das Lagerauge 4 eingesteckt werden kann. Der Zusatzarm 17 bildet nun gemeinsam mit dem Ausstellarm 1 eine Lenkerschere der Ausstellvorrichtung, die zum einen der Parallelführung des Flügels beim Kippöffnen und -schließen und zum anderen der Definierung der maximalen Kippöffnungsweite des Flügels dient.With the described displacement of the extension arm 1 in FIG. 1 to the right, the bearing eye 4 of the extension arm 1 enters one Position in which the bearing pin 18 of the additional arm 17 after Swiveling the additional arm 17 from its shown in Figure 1 Starting position can be inserted into the bearing eye 4. The Additional arm 17 now forms a handlebar scissors together with the extension arm 1 the display device, the one the parallel guide of the wing when opening and closing it and the other the definition of the maximum tilt opening width of the wing serves.

Gemäß Figur 2 wird die maximale Kippöffnungsweite des Flügels durch das Zusammenwirken des Schiebestücks 2 mit den Öffnungsbegrenzungsanschlägen 25 an der Stulpschiene 5 festgelegt. Da das flügelseitige Schwenklager des Zusatzarms 17 ebenso wie das rahmenseitige Schwenklager des Ausstellarms 1 beim Kippöffnen des Flügels ortsfest bleibt, verschiebt sich beim Überführen des Flügels ausgehend von der Schließ- in seine Kippöffnungslage das Schiebestück 2 in Verschieberichtung 9 gemäß Figur 2 so weit nach rechts, bis seine voreilende Stirnfläche an den flügelfesten Öffnungsbegrenzungsanschlägen 25 der Stulpschiene 5 zur Anlage kommt. Eine weitergehende Öffnungsbewegung des Flügels wird aufgrund der in Verschieberichtung 9 wirksamen Abstützung des Schiebestücks 2 an den Öffnungsbegrenzungsanschlägen 25 verhindert. Bei maximaler Kippöffnungsweite gemäß Figur 2 nimmt die Achse 3 des Ausstellarms 1 einen Abstand l1 von den Öffnungsbegrenzungsanschlägen 25 ein.According to Figure 2, the maximum tilt opening width of the wing is determined by the interaction of the sliding piece 2 with the opening limit stops 25 on the faceplate 5. Since the wing-side pivot bearing of the additional arm 17, like the frame-side pivot bearing of the extension arm 1, remains stationary when the wing is tilted open, when the wing is moved starting from the closed position into its tilt-open position, the sliding piece 2 shifts to the right in the direction of displacement 9 according to FIG. 2, until its leading end face comes into contact with the wing-fixed opening limit stops 25 of the faceplate 5. A further opening movement of the wing is prevented due to the effective support of the sliding piece 2 on the opening limit stops 25 in the direction of displacement 9. At the maximum tilt opening width according to FIG. 2, the axis 3 of the extension arm 1 is at a distance l 1 from the opening limit stops 25.

Wie aus Figur 3 hervorgeht ist gleichzeitig die in dieser Darstellung linke wellenförmige Erhebung 24 der Stulpschiene 5 im Innern der Wellenform 23 an dem Schiebestück 2 zu liegen gekommen. Aufgrund der elastischen Eigenschaften des Schiebestücks 2 hat sich dabei eine Rastverbindung zwischen dem Schiebestück 2 und der Stulpschiene 5 ergeben, welche einer Verschiebung des Schiebestücks 2 in den Figuren 2 und 3 nach links und somit einer Verringerung der Kippöffnungsweite des Flügels entgegenwirkt. Die Rastverbindung zwischen der Wellenform 23 des Schiebestücks 2 sowie der zugeordneten wellenförmigen Erhebung 24 der Stulpschiene 5 dient somit der Sicherung des Flügels gegen unbeabsichtigtes Schließen, wie es beispielsweise durch an dem Flügel angreifende Windkräfte verursacht werden kann. As can be seen from FIG. 3 is the one in this illustration left wave-shaped elevation 24 of the faceplate 5 in Inside the waveform 23 come to rest on the sliding piece 2. Due to the elastic properties of the sliding piece 2 there is a snap connection between the sliding piece 2 and the faceplate 5, which a shift of Sliding piece 2 in Figures 2 and 3 to the left and thus one Counteracts the reduction in the opening width of the wing. The Snap connection between the waveform 23 of the sliding piece 2 and the associated undulating elevation 24 of the faceplate 5 thus serves to secure the wing against accidental Close, such as by attacking the wing Wind forces can be caused.

Soll die maximale Kippöffnungsweite des Flügels verändert werden, so ist zunächst der Zusatzarm 17 von dem Ausstellarm 1 zu lösen. Zu diesem Zweck ist lediglich der Lagerzapfen 18 des Zusatzarms 17 aus dem Lagerauge 4 des Ausstellarms 1 herauszuziehen.If the maximum tilt opening width of the wing is to be changed, the auxiliary arm 17 must first be detached from the extension arm 1. For this purpose, only the bearing pin 18 of the additional arm 17 pull out of the bearing eye 4 of the extension arm 1.

Anschließend wird der in Einbaulage an dem festen Rahmen verbleibende Flügel ausgehend von seiner Kippöffnungsstellung gemäß den Figuren 2 und 3 in Schließrichtung bewegt. Damit verbunden ist eine Verschiebung des Schiebestücks 2 in den Figuren 2 und 3 nach links, bis die Flanken 15 des Keilausschnitts 14 der voreilenden Stirnfläche des Schiebestücks 2 an dem Anschlagzapfen 16 zur Anlage kommen. Der Ausstellarm 1 nimmt nun seine Montagestellung ein, und die Führungsvorsprünge 11 des Schiebestücks 2 liegen wieder innerhalb der Konturen der zugehörigen Ausnehmungen 10 der Stulpschiene 5, so daß das Gleitstück 2 senkrecht zu der Falzfläche des Flügels von der Stulpschiene 5 abgehoben werden kann. Anschließend wird, wie in Figur 5 durch einen Pfeil angedeutet, das Schiebestück 2 um seine Drehachse 3 gegenüber dem Ausstellarm 1 um 180° verschwenkt, ehe dann in der vorstehend ausführlich beschriebenen Art und Weise erneut eine senkrecht zu der Falzfläche des Flügels wirksame Formschlußverbindung zwischen dem Schiebestück 2 und somit dem Ausstellarm 1 und der Stulpschiene 5 und somit dem zugehörigen Flügel hergestellt wird. Abschließend läßt sich dann der Zusatzarm 17 in bekannter Weise mit dem Ausstellarm 1 verbinden. Der an dem Ausstellarm 1 angelenkte Zusatzarm 17 begrenzt den möglichen Verschiebeweg der Achse 3 des Ausstellarms 1 bzw. des Schiebestücks 2 in Verschieberichtung 9 derart, daß das Schiebestück 2 bei bestimmungsgemäßen Betrieb der Ausstellvorrichtung nicht in diejenige Position gelangen kann, in der es sich von der Stulpschiene 5 abheben läßt.Then the one remaining in the installed position on the fixed frame Wing based on its tilt opening position according to Figures 2 and 3 moved in the closing direction. Connected with it a shift of the sliding piece 2 in Figures 2 and 3 after left until the flanks 15 of the wedge section 14 of the leading ones End face of the sliding piece 2 on the stop pin 16 to the system come. The extension arm 1 now takes its assembly position a, and the guide projections 11 of the sliding piece 2 are again within the contours of the associated recesses 10 of the Forend rail 5, so that the slider 2 perpendicular to the fold surface of the wing can be lifted off the faceplate 5. Subsequently is, as indicated by an arrow in Figure 5, the Sliding piece 2 about its axis of rotation 3 relative to the extension arm 1 pivoted by 180 ° before then described in detail in the above Way again perpendicular to the fold surface of the wing effective positive connection between the sliding piece 2 and thus the extension arm 1 and the faceplate 5 and thus the associated wing is manufactured. Finally lets then the additional arm 17 in a known manner with the extension arm 1 connect. The additional arm 17 articulated on the extension arm 1 limits the possible displacement of the axis 3 of the extension arm 1 or the sliding piece 2 in the direction of displacement 9 such that the Sliding piece 2 when the opening device is operated as intended cannot get into the position in which it is can be lifted off the faceplate 5.

Wird nun der Flügel erneut in Kippöffnungsrichtung bewegt, so endet diese Bewegung, sobald das Schiebestück 2 mit seiner in Figur 6 rechten Stirnseite auf die Öffnungsbegrenzungsanschläge 25 aufläuft. Die Achse 3 des Ausstellarms 1 ist nunmehr mit einem Abstand l2 von den Öffnungsbegrenzungsanschlägen 25 der Stulpschiene 5 angeordnet. Nachdem der Abstand l2 nach Figur 6 größer ist als der Abstand l1 gemäß Figur 2, ergibt sich bei der in Figur 6 gezeigten Ausrichtung des Schiebestücks 2 eine gegenüber den in Figur 2 gezeigten Verhältnissen verminderte maximale Kippöffnungsweite des Flügels.If the sash is now moved again in the tilt opening direction, this movement ends as soon as the sliding piece 2 strikes the opening limiting stops 25 with its right end face in FIG. 6. The axis 3 of the extension arm 1 is now arranged at a distance l 2 from the opening limit stops 25 of the faceplate 5. Since the distance l 2 according to FIG. 6 is greater than the distance l 1 according to FIG. 2, the orientation of the sliding piece 2 shown in FIG. 6 results in a reduced maximum tilt opening width of the wing compared to the conditions shown in FIG.

Auch in seiner Kippöffnungsstellung gemäß Figur 6 ist der Flügel gegen unbeabsichtigtes Zuschlagen gesichert. Zu diesem Zweck ist die Wellenform 23 des Schiebestücks 2 mit der in Figur 7 rechten wellenförmigen Erhebung 24 der Stulpschiene 5 verrastet.The wing is also in its tilt opening position according to FIG. 6 secured against unintentional slamming. For this purpose the waveform 23 of the sliding piece 2 with the one on the right in FIG undulating elevation 24 of the faceplate 5 locked.
