Abstract

In the set-open device for a window, door or the like, a sliding piece (3) is mounted on the set-open arm (1) and a stop piece (7) on the additional arm (5), each in an articulated manner in an undercut fitting groove (9) of the at least tiltable casement (11), at least the sliding piece (3) being arranged in the fitting groove (9) so as to be longitudinally displaceable. The end tilt-open width of the casement (11) is limited as a result of an abutment of the sliding piece (3) on the stop piece (7) and is secured against unintended shutting by means of a spring-steel band (14) having a catch nose (17) which interacts releasably with a catch boss (29). So that the end tilt-open width of the casement (11) can be changed, without fitting parts being dismounted, either the sliding piece (3) or the stop piece (7) is subdivided into an articulation piece (20) carrying the point of articulation of the arm (1) or (5) and into a catch piece (21) which is adjustable along the fitting groove (9) in the region between the articulation piece (20) and counter piece (3) and can be fixed once again. The catch piece (21) can have a neck (23) for guidance within the articulation piece (20) and can be retained against the articulation piece (20) by means of a clamping screw (42). <IMAGE>

Description

Die Erfindung betrifft eine Ausstellvorrichtung für ein Fenster, eine Tür od. dgl., mit einem mindestens kippbaren Flügel, mit einem Ausstellarm, der im eingebauten Zustand an einem Ende in einem am Festrahmen befestigten Lagerbock und am anderen Ende an einem Gleitstück jeweils drehbar gelagert ist, und mit einem Zusatzarm, der einerseits am Ausstellarm, andererseits an einem Anschlagstück jeweils drehbar angelenkt ist, wobei das Gleitstück und das Anschlagstück im eingebauten Zustand in einer hinterschnittenen Beschlagnut eines aus Strangpreßprofilen hergestellten Flügelrahmens angeordnet sind und die die Öffnungsweite der Beschlagsnut begrenzenden Querstege von Längsstegen des Gleitstücks und des Anschlagstücks untergriffen sind und das Gleitstück in der Beschlagsnut längsverschiebbar geführt ist, während das Anschlagstück entweder in der Beschlagsnut ortsfest fixiert oder ebenfalls längsverschiebbar geführt ist und Gleitstück und Anschlagstück im eingebauten Zustand zur Begrenzung der Endkippöffnungsweite des Flügels mit ihren benachbarten Stirnflächen zur gegenseitigen Anlage gelangen, wobei Mittel vorgesehen sind zur Änderung der Endkippöffnungsweite und bei der Endkippöffnungsstellung des Flügels eine Zuschlagsicherung in Wirkung getreten ist, die aus einem Federstahlband mit Federzunge und Rastnase besteht, welche einen Rastnocken am Gegenstück lösbar hintergreift, und eines der in der Beschlagsnut angeordneten Stücke unterteilt ist in ein Anlenkstück und ein Raststück.The invention relates to an opening device for a window, a door or the like. With an at least tiltable wing, with an opening arm that is rotatably mounted in the installed state at one end in a bearing block attached to the fixed frame and at the other end on a slider , and with an additional arm, which is pivotally articulated on the one hand on the extension arm, on the other hand on a stop piece, the slide piece and the stop piece in the installed state being arranged in an undercut fitting groove of a sash frame made from extruded profiles and the transverse webs of longitudinal webs limiting the opening width of the fitting groove the slider and the stop piece are gripped and the slider is guided longitudinally displaceably in the fitting groove, while the stop piece is either fixed in the fitting groove or is also guided longitudinally displaceably and the slider and stop piece in the built-in Z. Condition to limit the end tilt opening width of the wing with their adjacent end faces for mutual contact, means are provided for changing the end tilt opening width and when the wing is in the end tilt opening position a surcharge has come into effect, which consists of a spring steel band with spring tongue and latching nose, which has a latching cam detachably engages behind the counterpart, and one of the pieces arranged in the fitting groove is divided into a link piece and a locking piece.

Eine derartige, aus dem DE-GM 7 520 486 vorbekannte Ausstellvorrichtung ermöglicht eine Änderung der Endkippöffnungsweite des Flügels unter Aufrechterhaltung der Funktion der Zuschlagsicherung. Die Verstellung der Endkippöffnungsweite des Flügels erfolgt bei einer aus Ausstellarm und daran angelenktem Zusatzarm bestehenden Ausstellvorrichtung, bei der beide Arme flügelseitig ein in einer hinterschnittenen Beschlagsnut angeordnetes Gleitstück und Anschlagstück tragen, durch Veränderung des in der Endkippöffnungsstellung wirksamen Abstands zwischen den flügelseitigen Anlenkstellen von Ausstellarm und Zusatzarm. Während der Kippöffnungsbewegung des Flügels bewegen sich Gleitstück und Anschlagstück aufeinander zu. Sobald die einander gegenüberliegenden Stirnflächen von Gleitstück und Anschlagstück zum gegenseitigen Anschlag kommen, ist die Kippöffnungsbewegung gestoppt und die Endkippöffnungsweite des Flügels erreicht. In dieser Endkippöffnungsstellung ist die Zuschlagsicherung in Funktion, die sicherstellt, daß der Flügel sich nicht unbeabsichtigt an den Festrahmen zurückbewegen kann. Die Zuschlagsicherung besteht aus einem an der Unterseite des Anschlagstücks befestigten Federstahlband, das mit einer über die dem Gleitstück zugewandten Stirnfläche hinausragenden Federzunge mit am freien Ende angeordneter Rastnase versehen ist, die einen ebenfalls an der Unterseite des Gleitstücks befindlichen Rastnocken lösbar hintergreift.Such an opening device, known from DE-GM 7 520 486, makes it possible to change the end tilt opening width of the wing while maintaining the function of the additional security. The adjustment of the end tilt opening width of the wing takes place in the case of an opening device comprising an extension arm and an additional arm articulated thereon, in which both arms on the wing side carry a slide piece and stop piece arranged in an undercut fitting groove, by changing the effective distance in the end tilt opening position between the wing-side articulation points of the extension arm and the additional arm. During the tilt opening movement of the wing, the sliding piece and the stop piece move towards one another. As soon as the opposing end faces of the sliding piece and stop piece come to a mutual stop, the tilt opening movement is stopped and the end tilt opening width of the wing is reached. In this end tilt opening position, the surcharge lock operates, which ensures that the sash cannot inadvertently move back to the fixed frame. The surcharge protection consists of a spring steel band attached to the underside of the stop piece, which is provided with a spring tongue protruding beyond the end face facing the slider with a detent arranged at the free end, which detachably engages behind a detent cam also located on the underside of the slider.

Um eine Änderung des wirksamen Abstands zwischen den flügelseitigen Anlenkstellen von Ausstellarm und Zusatzarm zur Veränderung der Endkippöffnungsweite des Flügels zu ermöglichen, ist die Anlenkstelle des Ausstellarms am Gleitstück in Längsrichtung der Beschlagsnut außermittig angeordnet. Damit sind die Abstände von der Anlenkstelle zur einen oder anderen Stirnfläche des Gleitstücks unterschiedlich groß. Durch Drehen des Gleitstücks um 180° sind somit zwei unterschiedliche Endkippöffnungsstellungen erzielbar.In order to allow a change in the effective distance between the wing-side articulation points of the extension arm and additional arm to change the end tilt opening width of the wing, the articulation point of the deployment arm is arranged off-center in the longitudinal direction of the fitting groove. The distances from the articulation point to one or the other end face of the slider are thus different. By rotating the slider by 180 °, two different end tilt opening positions can be achieved.

Die Änderung der Kippöffnungsweite erfordert einen Ausbau des in der Beschlagsnut geführten Anschlagstücks, damit dieses dann um 180° gewendet erneut in die Beschlagsnut eingeschoben werden kann. Dies ist sehr umständlich. Auch ist an beiden Enden des Gleitstücks die Anordnung je eines Rastnockens notwendig, wobei jeweils nur einer der Rastnocken in Funktionsstellung benötigt und benutzt wird. Bedingt durch die Wendbarkeit des Gleitstücks um 180° sind nur zwei unterschiedliche Endkippöffnungsweitenbegrenzungen erreichbar.The change in the tilt opening width requires an expansion of the stop piece guided in the fitting groove so that it is then turned through 180 ° again into the fitting groove can be inserted. This is very cumbersome. At both ends of the slider, the arrangement of a latching cam is necessary, only one of the latching cams being required and used in the functional position. Due to the reversibility of the slider by 180 °, only two different end tilt opening width limits can be reached.

Um vier Einstellmöglichkeiten zu erhalten, kann auch das Anschlagstück zur Anlenkstelle des Zusatzarms entsprechend asymmetrisch ausgestaltet und an beiden Enden ebenfalls mit Rastnocken versehen werden. Zusätzlich ist jedoch ein zwischen Gleitstück und Anschlagstück in der Beschlagsnut gelagertes Distanzstück erforderlich, das dann an beiden Enden je eine Federzunge mit Rastnase aufweisen muß, damit das Distanzstück sowohl mit den Rastnocken des Gleitstücks als auch den Rastnocken des Anschlagstücks gleichzeitig zusammenwirken kann, wobei dann jeweils zwei Rastnocken unbenutzt sind.In order to obtain four setting options, the stop piece to the articulation point of the additional arm can also be designed correspondingly asymmetrically and can also be provided with latching cams at both ends. In addition, however, a spacer mounted between the slider and the stop piece in the fitting groove is required, which must then have a spring tongue with a detent at both ends so that the spacer can interact with both the detent cams of the slider and the detent cams of the stop piece, in which case each two locking cams are unused.

Eine Änderung der Endkippöffnungsweite des Flügels, wobei in dessen Endkippöffnungsstellung eine Zuschlagsicherung wirksam wird, ist auch aus der EP-A 0 316 555 bekannt. Der Ausstellarm ist am flügelseitigen Ende mit einem Bundbolzen versehen, der ein Langloch einer im Falz des Flügels befestigten Stulpschiene durchgreift und darin gleitbar gelagert ist. Die Endkippöffnungsweite des Flügels ist beim Anschlagen des Bundbolzens an einem Ende des Langlochs erreicht.EP-A 0 316 555 also discloses a change in the end tilt opening width of the wing, in which case an additional lock is effective in its end tilt opening position. The extension arm is provided at the wing-side end with a collar bolt which passes through an elongated hole of a faceplate fastened in the fold of the wing and is slidably mounted therein. The end opening of the wing is reached when the collar bolt is struck at one end of the elongated hole.

Zur Änderung der wirksamen Länge des Langlochs dient ein aus einem Federstahlband bestehendes Anschlagstück, das auf die Oberfläche der Stulpschiene aufzusetzen und mit einem Zapfen in eine von mehreren Aufnahmebohrungen der Stulpschiene einzustecken ist, wobei eine Abbiegung des Federstahlbandes in das Langloch eingreift und damit den Verschiebeweg des Bundbolzens des Ausstellarms begrenzt. Zur Sicherung des Anschlagstücks gegen ein ungewolltes Aushängen stützt es sich in allen Betriebsstellungen an der Unterseite des Ausstellarms ab.To change the effective length of the elongated hole, a stop piece consisting of a spring steel band is used, which is to be placed on the surface of the faceplate and inserted with a pin into one of several receiving bores in the faceplate, with a bend in the spring steel band engaging in the elongated hole and thus the Limited movement of the flanged arm of the extension arm. To secure the stop piece against unwanted unhooking, it is supported in all operating positions on the underside of the extension arm.

Um das aufgesetzte Anschlagstück um das Maß des Abstands der Aufnahmebohrungen versetzen zu können, muß die Überdeckung durch den Ausstellarm aufgehoben werden, beispielsweise durch das bewußte Herbeiführen einer Fehlbedienungsstellung des Flügels und/oder durch ein Lösen des Ausstellarms von der Stulpschiene.In order to be able to move the stop piece by the measure of the distance between the receiving bores, the overlap must be removed by the raising arm, for example by deliberately causing the wing to be operated incorrectly and / or by releasing the raising arm from the faceplate.

Aufgabe der Erfindung ist es, eine gattungsgemäße Ausstellvorrichtung zu schaffen, bei der die Änderung der Endkippöffnungsweite ohne Ausbau von Beschlagteilen ermöglicht ist unter Erzielung einer feinstufigen bzw. stufenlosen Einstellung.The object of the invention is to provide a generic opening device, in which the change of the tip opening is possible without removing fittings, while achieving a fine or stepless adjustment.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Raststück mit einem Hals in das zumindest im Kupplungsbereich mit U-förmigem Querschnitt versehene Anlenkstück eingreift, an der Innenseite des die Schenkel des U verbindenden Flansches anliegend ist und eine Spannschraube ein Langloch im Flansch durchdringt und in eine Gewindebohrung im Hals eingedreht ist, so daß das zwischen Anlenkstück und Gegenstück gelagerte Raststück entlang der Beschlagsnut längsverstellbar und feststellbar am Anlenkstück angeordnet ist.This object is achieved in that the locking piece engages with a neck in the at least in the coupling area provided with a U-shaped cross-section, is adjacent to the inside of the legs of the U connecting flange and a clamping screw penetrates an elongated hole in the flange and into a Threaded bore is screwed into the neck so that the locking piece mounted between the link piece and counterpart is arranged along the fitting groove in a longitudinally adjustable and lockable manner on the link piece.

Das durch eine Unterteilung des Gleitstücks und/oder des Anschlagstücks entstandene, mit den zur Zuschlagsicherung erforderlichen Mitteln versehene Raststück befindet sich zwischen den die Anlenkstelle des Austellarms bzw. des Zusatzarms tragenden Anlenkstücken. Bei einem dem Anlenkstück für den Zusatzarm zugeordneten Raststück kann dieses z. B. mit dem Rastnocken versehen sein, wobei die Rastnase sich dann am Gleitstück befindet. Der Rastnocken des Raststücks, das mit dem Anlenkstück das Anschlagstück bildet, ist in seiner Ausrichtung zur Rastnase angeordnet. Diese Ausrichtung bleibt bei Änderungen der wirksamen Länge der Anlenkstellen unverändert beibehalten, da die erforderliche Relativverschiebung zwischen Raststück und Anlenkstück entlang der Beschlagsnut erfolgt, also jeweils auf den Rastpartner der Zuschlagsicherung zu. Die Wirkungs- und Arbeitsweise der Zuschlagsicherung ist damit von der jeweiligen Endkippöffnungsweite unabhängig und es sind jeweils dieselben Mittel im selben Eingriff. Da die Änderung des wirksamen Abstands durch das längs der Beschlagsnut längsverschiebbare Raststück geschieht, kann die Verstellung bei am Flügel eingebauter Ausstellvorrichtung durchgeführt werden. Die Spannschraube zum Festlegen des Raststücks am Anlenkstück ist dabei relativ frei zugänglich. Der Hals des am Anlenkstück klemmbefestigten Raststücks kann zur Längsführung des Raststücks herangezogen werden. Die Lagerung des Halses im Anlenkstück führt zu einer kompakten Baueinheit. Nach dem Lokkern der Spannschraube ist das Raststück beispielsweise stufenlos zum Anlenkstück längs zu verschieben und nach Erreichen der bestimmten Position zur Erzielung der gewünschten Endkippöffnungsweite wieder anzuziehen.The locking piece, which is created by dividing the slide piece and / or the stop piece and provided with the means required for securing the supplement, is located between the articulation pieces carrying the articulation point of the extension arm or the additional arm. In a locking piece assigned to the hinge piece for the additional arm, this z. B. be provided with the locking cam, the The latch is then on the slide. The locking cam of the locking piece, which forms the stop piece with the articulation piece, is arranged in its orientation to the locking lug. This orientation remains unchanged in the event of changes in the effective length of the articulation points, since the required relative displacement between the locking piece and the articulation piece takes place along the fitting groove, that is, in each case toward the locking partner of the securing device. The effectiveness and mode of operation of the supplementary security is therefore independent of the respective tip opening width and the same means are involved in the same procedure. Since the effective distance is changed by the locking piece which is longitudinally displaceable along the fitting groove, the adjustment can be carried out with the opening device installed on the sash. The clamping screw for fixing the locking piece on the hinge piece is relatively freely accessible. The neck of the locking piece clamped on the articulation piece can be used for the longitudinal guidance of the locking piece. The storage of the neck in the link piece leads to a compact structural unit. After the locomotive core of the tensioning screw, the locking piece is, for example, continuously displaceable longitudinally to the articulation piece and tightened again after reaching the specific position in order to achieve the desired final tilt opening.

Bei einer Ausstellvorrichtung, bei welcher das Anschlagstück ortsfest in der Beschlagsnut fixiert ist, besteht eine günstige Ausführungsform darin, daß das Raststück dem Anlenkstück für den Zusatzarm zugeordnet ist, ein an den Hals anschließendes, mit einem Hohlraum versehenes Kopfteil aufweist, wobei an der Innenseite der Seitenwände des Kopfteils jeweils ein Rastnocken angeordnet ist. Der zwischen Anlenkstück und Gleitstück angeordnete Kopfteil ist gegenüber dem Hals im Querschnitt vergrößert auf eine Breite die geringfügig kleiner ist als die Öffnungsweite der Beschlagsnut zwischen deren Querstegen, so daß im Hohlraum des Kopfteils ausreichend Platz ist für die Anordnung von Rastnocken für die Zuschlagssicherung, die damit verdeckt untergebracht ist. Da das Raststück ohne Untergriff zu den Querstegen der Beschlagsnut ist, läßt es sich leicht einbauen und auch noch nachträglich austauschen, ohne daß sonstige Beschlagteile dafür hinderlich wirken.In an opening device in which the stop piece is fixed in place in the fitting groove, a favorable embodiment consists in that the locking piece is assigned to the articulation piece for the additional arm, has a head part adjoining the neck and provided with a hollow space, a latching cam being arranged on the inside of the side walls of the head part. The head part arranged between the articulation piece and the sliding piece is enlarged in cross-section with respect to the neck to a width which is slightly smaller than the opening width of the fitting groove between its transverse webs, so that there is sufficient space in the cavity of the head part for the arrangement of latching cams for securing the knockdown, so that is concealed. Since the locking piece is without a handle to the crossbars of the fitting groove, it can be easily installed and also replaced afterwards, without other fitting parts acting as a hindrance.

Es ist zweckmäßig, daß der Rastnocken einen dreieckförmigen Querschnitt aufweist mit dem Gleitstück zugewandter, flach geneigter Auflauffläche mit anschließend in entgegengesetzter Richtung stark geneigter Haltefläche zum Hintergreifen durch eine am freien Ende der Federzunge angeordnete Rastnase dreieckförmigen Querschnitts mit korrespondierend ausgebildetem Haltesteg und das freie Ende der Federzunge bildendem Auflaufsteg. Bei der Annäherung des mit der Federzunge versehenen Gleitstücks an das Raststück gelangen die Rastnasen im Innern des Raststücks mit ihrem Auflaufsteg in Kontakt mit der Auflauffläche des Rastnockens, werden durch diese aufeinander zubewegt und damit unter Vorspannung gesetzt. Am Übergang zu den Halteflächen des Rastnockens bedingt die Vorspannung der Rastnasen eine Auseinanderbewegung der Rastnasen voneinander und damit das Einschnappen der Rastnasen hinter die Halteflächen der Rastnocken. Es wird durch die flache Neigung der Auflauffläche ein sanftes Abbremsen und Auflaufen erreicht bei sicherer Haltekraft der in Wirkstellung gebrachten Zuschlagssicherung infolge der steil geneigten Halteflächen.It is expedient that the locking cam has a triangular cross-section with the slider facing, flat-inclined ramp surface with a subsequently inclined holding surface in the opposite direction for reaching behind by a triangular cross-section arranged at the free end of the spring tongue with a correspondingly designed retaining web and the free end of the spring tongue forming catwalk. When the sliding piece provided with the spring tongue approaches the locking piece, the locking lugs in the interior of the locking piece come into contact with the contact surface of the locking cam with their ramp and are moved towards one another by them and thus set under tension. At the transition to the retaining surfaces of the latching cam, the pretensioning of the latching lugs causes the latching lugs to move apart from one another and thus causes the latching lugs to snap behind the retaining surfaces of the latching cams. Due to the flat inclination of the run-up surface, gentle braking and bumping is achieved with the holding force of the supplementary safety device brought into the active position due to the steeply inclined holding surfaces.

Zur Erreichung definierter Endkippöffnungsstellungen des Flügels können an der Innenseite des Flansches des Anlenkstücks und an der Anlagefläche des Halses des Raststücks Vorsprünge in Vertiefungen form- und kraftschlüssig eingreifend angeordnet sein. Im allgemeinen reicht es aus, drei unterschiedliche Kippöffnungsstellungen zu ermöglichen. Die ineinandergreifenden Vorsprünge und Vertiefungen sind an der Kontaktfläche zwischen Hals des Raststücks und Flansch des Anschlagstücks und werden durch die Spannschraube in Eingriff gehalten, wodurch sie weiterhin als Sicherung gegen ein unbeabsichtigtes Verändern der Zuordnung Raststück/Anlenkstück dienen.In order to achieve defined end tilt opening positions of the wing, projections can be arranged in recesses with positive and non-positive engagement on the inside of the flange of the articulation piece and on the contact surface of the neck of the locking piece. In general, it is sufficient to enable three different tilt opening positions. The interlocking projections and depressions are on the contact surface between the neck of the locking piece and the flange of the stop piece and are held in engagement by the clamping screw, whereby they continue to serve as a safeguard against inadvertent change in the assignment of the locking piece / link piece.

Wenn in günstiger Ausgestaltung die Vertiefungen an der Innenseite des Flansches zu beiden Seiten des Langlochs angeordnet sind und die damit korrespondierenden Vorsprünge im Bereich der Gewindebohrung des Halses, dann wirkt die durch die Spannschraube hervorgerufene Kraft unmittelbar in demjenigen Bereich, wo die ein ungewolltes Verschieben zwischen Raststück und Anlenkstück wirkenden Kräfte auftreten.If, in a favorable embodiment, the depressions on the inside of the flange are arranged on both sides of the elongated hole and the corresponding projections in the area of the threaded hole in the neck, then the force caused by the clamping screw acts directly in the area where there is an unintentional displacement between the locking piece and linkage forces acting.

Ist das Raststück lösbar am Anlenkstück befestigt und sind entsprechende Rastnocken für die Rastnase der Federzunge zusätzlich im U-förmigen Kupplungsbereich des Anlenkstücks angeordnet, ergibt sich eine weitere Endkippöffnungsstellung dadurch, daß das Raststück entfernt wird. Insbesondere ergibt sich der Vorteil, daß dasselbe Anlenkstück angewendet werden kann, unabhängig davon, ob eine Anderung der Kippöffnungsweite gewünscht und ermöglicht ist oder ob eine Kippöffnungsweitenänderung ausgeschlossen werden soll, wobei jeweils die Funktion der Zuschlagssicherung unverändert beibehalten ist.If the locking piece is detachably fastened to the articulation piece and corresponding locking cams for the locking lug of the spring tongue are additionally arranged in the U-shaped coupling area of the articulation piece, a further end tilt opening position results from the fact that the locking piece is removed. In particular, there is the advantage that the same articulation piece can be used, regardless of whether a change in the tilt opening width is desired and possible or whether a change in the tilt opening width should be ruled out, the function of the supplementary security being retained unchanged in each case.

Der Ausstellarm 1 einer Ausstellvorrichtung ist einerends in einem nicht dargestellten Lagerbock drehbar gelagert, der am Festrahmen eines Fensters anzuschrauben ist und trägt anderenends mittels eines Bundbolzens 2 drehbar ein Gleitstück 3. Am Ausstellarm 1 ist weiterhin in einem Bolzen 4 ein Zusatzarm 5 angelenkt, dessen flügelseitiger Bundzapfen 6 wiederum drehbar an einem Anschlagstück 7 befestigt ist. Gleitstück 3 und Anschlagstück 7 sind mit Längsstegen 8 ausgerüstet, welche die die Öffnungsweite einer Beschlagsnut 9 begrenzenden Querstege 10 untergreifen. Die hinterschnittene Beschlagsnut 9 befindet sich an der Oberseite des aus Strangpreßprofilen hergestellten Flügelrahmens 11.The extension arm 1 of an opening device is rotatably supported at one end in a bearing block (not shown) which is to be screwed to the fixed frame of a window and at the other end rotatably supports a sliding piece 3 by means of a collar bolt 2. An extension arm 5 is also articulated on the extension arm 1 in a bolt 4, the wing side of which Collar pin 6 is in turn rotatably attached to a stop piece 7. The sliding piece 3 and the stop piece 7 are equipped with longitudinal webs 8 which engage under the transverse webs 10 which limit the opening width of a fitting groove 9. The undercut fitting groove 9 is located on the upper side of the sash 11 made from extruded profiles.

Das Gleitstück 3 besteht aus einem Aluminiumprofil mit einem im wesentlichen Ω -förmigen Querschnitt mit außerhalb des Bereichs der Beschlagsnut 9 angeordneter Kammer 12, an deren Boden 13 ein Federstahlband 14 befestigt ist, das zwei die Stirnfläche 15 des Gleitstücks 3 überragende Federzungen 16 mit an deren freien Ende angeordneter Rastnase 17 aufweist. Die Rastnase 17 besitzt im wesentlichen eine Dreiecksform mit einem steil geneigt angeordneten Haltesteg 18 und einem anschließenden, in entgegengesetzter Richtung schwach geneigten Auflaufsteg 19.The slider 3 consists of an aluminum profile with a substantially Ω-shaped cross-section with a chamber 12 arranged outside the area of the fitting groove 9, to the bottom 13 of which a spring steel band 14 is fastened, which two spring tongues 16 projecting beyond the end face 15 of the slider 3 with their other has free end arranged locking lug 17. The locking lug 17 has essentially a triangular shape with a steeply inclined holding web 18 and a subsequent, in opposite direction slightly inclined runway 19.

Das Anschlagstück 7 ist in ein die Anlenkstelle mit dem Zusatzarm 5 aufnehmendes Anlenkstück 20 und in ein damit verbundenes Raststück 21 unterteilt.The stop piece 7 is subdivided into a joint piece 20 receiving the articulation point with the additional arm 5 and into a detent piece 21 connected thereto.

Das Raststück 21 besteht aus einem Kopfteil 22, an das sich ein Hals 23 anschließt, der nahe seinem freien Ende eine Gewindebohrung 24 aufweist. Der gehäuseartig ausgebildete Kopfteil 22 trägt an den beiden in Langsrichtung der Beschlagsnut 9 sich erstreckenden Seitenwänden 25 an deren Innenseite 28 angeformte Rastnocken 29 dreieckförmigen Querschnitts mit flach geneigter Auflauffläche 30 und in entgegengesetzter Richtung stark geneigter Haltefläche 31. Das Kopfteil 22 ist begrenzt durch die dem Anlenkstück 20 zugewandte Stirnwand 32.The locking piece 21 consists of a head part 22, which is followed by a neck 23 which has a threaded bore 24 near its free end. The housing-like head part 22 carries on the two side walls 25, which extend in the longitudinal direction of the fitting groove 9, on the inside 28 molded locking cams 29 of triangular cross-section with a flat inclined run-up surface 30 and a holding surface 31 which is strongly inclined in the opposite direction. The head part 22 is limited by the articulation piece 20 facing end wall 32.

Das Anlenkstück 20 trägt die Anlenkstelle für den Zusatzarm 5 und ist mittels Schneidschrauben 33, welche die Querstege 10 der Beschlagsnut 9 teilweise perforieren, ortsfest in der Beschlagsnut 9 befestigt. An seinem dem Raststück 21 zugewandten Kupplungsbereich besitzt das Anlenkstück 20 einen im wesentlichen U-förmigen Querschnitt, dessen Flansch 34 mit einem Langloch 35 versehen ist und dessen beide Schenkel 36 jeweils einen Rastnokken 37 tragen, der dem Rastnocken 29 des Raststücks 21 entspricht. An der Innenseite 38 des Flansches 34 befinden sich zu beiden Seiten des Langlochs 35 je drei hintereinanderliegende Vertiefungen 39 zum Zusammenwirken mit korrespondierenden Vorsprüngen 40 im Bereich der Gewindebohrung 24 des Halses 23. Die Festlegung des mit seinem Hals 23 in das Anlenkstück 20 eingreifenden Raststücks 21 erfolgt mittels einer das Langloch 35 durchsetzenden und in die Gewindebohrung 24 eingedrehten Spannschraube 42.The articulation piece 20 carries the articulation point for the additional arm 5 and is fixed in place in the fitting groove 9 by means of self-tapping screws 33 which partially perforate the transverse webs 10 of the fitting groove 9. At its coupling area facing the locking piece 21, the articulation piece 20 has an essentially U-shaped cross section, the flange 34 of which is provided with an elongated hole 35 and the two legs 36 of which each carry a locking cam 37 which corresponds to the locking cam 29 of the locking piece 21. On the inside 38 of the flange 34 there are three consecutive depressions 39 on each side of the elongated hole 35 for interacting with corresponding projections 40 in the region of the threaded bore 24 of the neck 23. The locking piece 21 engaging with the neck 23 in the articulation piece 20 is established by means of a clamping screw 42 passing through the elongated hole 35 and screwed into the threaded bore 24.

Die Endkippöffnungsweite des Flügels ergibt sich, wenn die Stirnfläche 15 des Gleitstücks 3 an der Stirnfläche 41 des Raststücks 21 anliegend ist. In Fig. 1 ist in der unteren Darstellung die größte Endkippöffnungsweite des Flügelrahmens 11 dargestellt. Dabei liegt die Stirnwand 32 des Kopfteils 22 des Raststücks 21 an der Stirnfläche 43 des Anlenkstücks 20 an und die Spannschraube 42 befindet sich nahe des von der Stirnfläche 43 abgewandten Endes des Langlochs 35. Der trapezförmige Vorsprung 40 an der Anlagefläche 44 des Halses 23 greift in die am entferntest von der Stirnfläche 43 liegende trapezförmige Vertiefung 39 ein.The end tilt opening width of the wing results when the end face 15 of the sliding piece 3 bears against the end face 41 of the latching piece 21. In Fig. 1, the largest end tilt opening width of the casement 11 is shown in the lower representation. The end wall 32 of the head part 22 of the locking piece 21 lies against the end face 43 of the articulation piece 20 and the clamping screw 42 is located near the end of the elongated hole 35 facing away from the end face 43. The trapezoidal projection 40 on the contact surface 44 of the neck 23 engages in the most distant trapezoidal depression 39 from the end face 43.

Zur Änderung der Endkippöffnungsweite ist bei teilgeöffnetem Flügel die Spannschraube 42 zu lockern, das Raststück 21 nach links vom Anlenkstück 20 weg in Längsrichtung der Beschlagsnut 9 zu verschieben, bis der Vorsprung 40 des Halses 23 bei einem erneuten Anziehen der Spannschraube 42 in eine andere Vertiefung 39 eingedrückt wird. Diese Verschiebung des Raststücks 21 vom Anlenkstück 20 weg ergibt eine Verkleinerung der Endkippöffnungsweite des Flügels.To change the opening of the end of the opening, loosen the clamping screw 42 when the sash is partially open, move the locking piece 21 to the left of the coupling piece 20 in the longitudinal direction of the fitting groove 9 until the projection 40 of the neck 23 when the clamping screw 42 is tightened again into another recess 39 is pushed in. This displacement of the locking piece 21 away from the articulation piece 20 results in a reduction in the end tilt opening width of the wing.

Im allgemeinen reichen drei unterschiedliche Endkippöffnungsstellungen aus, so daß durch die Vertiefungen 39 und den Vorsprung 40 drei definierte Zuordnungen des Raststücks 21 zum Anlenkstück 20 vorliegen, wobei die Spannschraube 42 entweder nahe einem der beiden Enden des Langlochs 35 oder in dessen Längsmitte angeordnet ist. Mit diesen drei Einstellmöglichkeiten kann z. B. eine Kippöffnungsweite von 120, 100 und 80 mm erreicht werden, wozu ein Verstellbereich des Raststücks 21 gegenüber dem Anlenkstück 20 von 7 mm ausreichend ist. Da durch die Einstellmöglichkeit des Raststücks 21 seine relative Zuordnung zum Gleitstück 2 und damit der Federzunge 16 mit Rastnase 17 zu dem Rastnocken 29 unverändert bleibt, wird die Funktion der Zuschlagssicherung nicht beeinflußt und sie ist bei der jeweiligen Endkippöffnungsweite jeweils in gleichbleibendem Eingriff.In general, three different end tilt opening positions are sufficient so that there are three defined assignments of the locking piece 21 to the articulation piece 20 through the depressions 39 and the projection 40, the tensioning screw 42 being arranged either near one of the two ends of the elongated hole 35 or in the longitudinal center thereof. With these three setting options, e.g. B. a tilt opening width of 120, 100 and 80 mm can be achieved, for which an adjustment range of the locking piece 21 relative to the articulation piece 20 of 7 mm is sufficient. Since its relative assignment to the slider 2 and thus the spring tongue 16 with the latching lug 17 to the latching cam 29 remains unchanged due to the possibility of adjustment of the latching piece 21, the function of the supplementary lock is not influenced and it is in constant engagement at the respective tip opening width.

Im Ausführungsbeispiel ist die Ausgestaltung des von dem Federstahlband 14 beaufschlagten Sicherungsbereichs aus dem Raststück 21 zusätzlich übertragen auf das Anlenkstück 20. Dies ermöglicht es, das Anlenkstück 20 in unveränderter Form bei weggelassenem Raststück 21 als Anschlagstück mit Zuschlagssicherung zu verwenden, wenn eine Endkippöffnungsweitenänderung nicht gewünscht ist. Weiterhin ist es möglich, ausgehend von der Lösung der Fig. 1, auch dort das Raststück 21 wegzulassen, so daß die Stirnfläche 15 des Gleitstücks 3 unmittelbar an der Stirnfläche 43 des Anlenkstücks 20 zur Anlage kommen kann. Es ergibt sich dann eine wesentlich auf 180 mm vergrößerte maximale Endkippöffnungsweite des Flügels.In the exemplary embodiment, the configuration of the securing area acted upon by the spring steel strip 14 is also transferred from the latching piece 21 to the articulation piece 20. This makes it possible to use the articulation piece 20 in an unchanged form with the latching piece 21 omitted as a stop piece with an additional securing device if a change in the tip opening opening is not desired . Furthermore, starting from the solution in FIG. 1, it is also possible to omit the locking piece 21 there, so that the end face 15 of the sliding piece 3 can come to rest directly on the end face 43 of the articulation piece 20. This then results in a maximum end tilt opening width of the wing that has been significantly increased to 180 mm.
