Abstract

The opening device for a window, door or the like has an opening arm (1) with a reinforcing piece (16) which is arranged on its underside (15) and which itself carries an axle pin (23) passing through and engaging with its head (24) behind an angle piece (4) of the pivot bearing located on the fixed frame. After an axial displacement between the angle piece (4) and opening arm (1), the opening arm (1) is rotatable through 180 DEG relative to the angle piece (4) for either left-hand or right-hand use. So that a higher load-bearing capacity is obtained, without an increase in the constructional height, arranged on the angle piece (4) is a flange (11) which extends essentially parallel to the narrow side (12) of the opening arm (1) and of which the nose (13), in the fixed rotary end positions, is mounted so as to be guided between the opening arm (1) and a respective web (20) of the reinforcing piece (16). The axle pin (23) can be a screw screwed into the reinforcing piece (16) for adjusting the effective spacing between the opening arm (1) and angle piece (4) without impairing the right-hand/left-hand change-over capacity. <IMAGE>

Description

Die Erfindung betrifft eine Ausstellvorrichtung für ein Fenster, eine Tür od. dgl., insbesondere mit einem Drehkippflügel, deren Ausstellarm flachrechteckigen Querschnitts einerends an einem Drehlager angeordnet ist, das aus einem am Festrahmen befestigbaren Lagerbock und einem daran um einen Lagerbolzen drehbar gelagerten Winkelstück besteht, wobei ein Winkelschenkel des Winkelstücks eine sich rechtwinklig zum Lagerbolzen erstreckende und dazu seitlich versetzt angeordnete Bohrung aufweist, wobei die Achse der Bohrung in einer Ebene rechtwinklig zur Lagerbolzenachse liegt und die Bohrung einen Achsbolzen aufnimmt, der den Winkelschenkel auf der vom Ausstellarm abgewandten Seite mit einem Kopf hintergreift und der Achsbolzen an einem an der Unterseite und nahe dem Ende des Ausstellarms befestigten Verstärkungsstück mit geringerer Breite wie der Ausstellarm angeordnet ist und nach einer Axialverschiebung entlang der Achse des Achsbolzens zwischen Ausstellarm und Winkelstück der Ausstellarm relativ zum Winkelstück in zwei um 180° bezüglich der Achse des Achsbolzens zueinander versetzten Drehlagen durch zwischen dem Winkelstück und dem Ausstellarm wirkende, ineinandergreifende Sicherungsmittel fixierbar ist, wobei der Axialverschiebeweg größer ist als die gegenseitige Eingriffstiefe der Sicherungsmittel.The invention relates to an opening device for a window, a door or the like, in particular with a tilt-and-turn sash, the opening arm of which has a flat, rectangular cross section and is arranged at one end on a pivot bearing which consists of a bearing block which can be attached to the fixed frame and an angle piece which is rotatably mounted thereon about a bearing pin wherein an angle leg of the angle piece has a bore which extends at right angles to the bearing pin and is laterally offset, the axis of the hole lies in a plane perpendicular to the bearing pin axis and the bore receives an axle pin which has a head on the side facing away from the deployment arm engages behind and the axle bolt is arranged on a reinforcement piece which is fastened to the underside and near the end of the deployment arm and is of a smaller width than the deployment arm and after an axial displacement along the axis of the axle bolt between the deployment arm and the angle piece The extension arm can be fixed relative to the contra-angle in two rotational positions offset from one another by 180 ° with respect to the axis of the axle bolt by interlocking securing means acting between the contra-angle and the extending arm, the axial displacement path being greater than the mutual engagement depth of the securing means.

Bei einer derartigen, aus der AT-A 4879/75 vorbekannten Ausstellvorrichtung dient ein Mehrkantansatz am freien Ende des Achsbolzens in Verbindung mit einer korrespondierenden Mehrkantausnehmung des Winkelschenkels des Winkelstücks, in das der Mehrkantansatz formschlüssig eingreift, als Sicherung gegen ein ungewolltes Verdrehen des Winkelstücks und damit des Drehlagers gegenüber dem Ausstellarm. Durch eine Axialverschiebung zwischen Ausstellarm und Winkelstück wird der Formschluß gelöst und damit ist an sich eine freie Drehbarkeit des Drehlagers um den Achsbolzen des Ausstellarms ermöglicht. Da zur Links-/Rechtsumstellung der Ausstellvorrichtung zwei um 180° versetzte Drehlagen des Winkelstücks zum Ausstellarm ausreichend sind, wird nach einer 180°-Relativdrehung der Mehrkantkopf mittels einer zwischen dem Verstärkungsstück und dem Winkelschenkel zwischengeschalteten Druckfeder erneut zum Einrasten mit der Mehrkantausnehmung gebracht. Zur Aufnahme der Druckfeder ist eine Erweiterung innerhalb des Winkelschenkels erforderlich, wodurch die Führungsflächen für den Achsbolzen innerhalb des Winkelschenkels wesentlich verringert sind. Diese Führungsflächen müssen vom Flügel hervorgerufene, über den Ausstellarm und das Drehlager in den Festrahmen abzuleitende Kräfte aufnehmen.In such an opening device known from AT-A 4879/75, a polygonal attachment at the free end of the axle bolt in conjunction with a corresponding polygonal recess of the angle leg of the angle piece, into which the polygonal attachment engages in a form-fitting manner, serves as a safeguard against unwanted twisting of the angle piece and thus the pivot bearing opposite the extension arm. The positive engagement is released by an axial displacement between the extension arm and the contra-angle handpiece, and thus the pivot bearing can be rotated freely around the pivot pin of the extension arm. Since two positions of the contra-angle to the extension arm offset by 180 ° are sufficient for the left / right changeover of the opening device are, after a 180 ° relative rotation of the polygonal head by means of a pressure spring interposed between the reinforcing piece and the angle leg made to engage again with the polygonal recess. To accommodate the compression spring, an extension within the angle leg is required, as a result of which the guide surfaces for the axle pin within the angle leg are significantly reduced. These guiding surfaces must absorb the forces generated by the sash, which must be dissipated in the fixed frame via the extension arm and the pivot bearing.

Diese Kräfte können insbesondere bei Toleranzen zwischen dem Durchmesser des Achsbolzens und der Bohrung des Winkelstücks ungünstige spezifische Beanspruchungen hervorrufen. Somit ist bei Flügel mit größeren Gewichten und/oder ungünstigen Formaten eine verstärkte Ausführung erforderlich und eine damit verbundene Vergrößerung der Abmessungen der Ausstellvorrichtung im Bereich des Winkelstücks. Auch beschränkt sich der zur Kraftübertragung vorgesehene Bereich nur über die Länge des Winkelschenkels. Mittel zur Verstellung des wirksamen Abstands zwischen Winkelstück und Ausstellarm, wie sie zweckmäßig sind, um z. B. einen abgesackten Flügel wieder anheben zu können, sind beim gattungsbildenden Stand der Technik nicht vorhanden. Deren Anwendung steht dort der Mehrkantformschluß am freien Ende des Achsbolzens entgegen.These forces can cause unfavorable specific stresses, particularly in the case of tolerances between the diameter of the axle bolt and the bore of the contra-angle handpiece. Thus, in the case of sashes with larger weights and / or unfavorable formats, a reinforced design is required and the dimensions of the opening device in the region of the contra-angle handpiece are enlarged. The area provided for power transmission is also limited only over the length of the angle leg. Means for adjusting the effective distance between the elbow and extension arm, as are appropriate to z. B. to be able to lift a sagged wing again, are not available in the generic state of the art. Their application is opposed to the polygonal form fit at the free end of the axle bolt.

Aufgabe der Erfindung ist es, eine gattungsgemäße Ausstellvorrichtung zu schaffen, bei welcher ohne Vergrößerung der Bauhöhe und bei gleichzeitiger Begrenzung der Relativdrehverlagerung zwischen Ausstellarm und Winkelstück auf 180° eine größere Belastbarkeit an dem Übergang von Ausstellarm zum Winkelstück erhalten wird, wobei gleichzeitig noch die Anordnung einer Vorrichtung zur Verstellung des wirksamen Abstands zwischen Winkelstück und Ausstellarm ermöglicht ist.The object of the invention is to provide a generic display device, in which a greater load capacity is obtained at the transition from the display arm to the angle piece without increasing the overall height and at the same time limiting the relative rotational displacement between the display arm and angle piece, while at the same time still arranging one Device for adjusting the effective distance between the elbow and extension arm is made possible.

Dies wird bei einer gattungsgemäßen Ausstellvorrichtung dadurch erreicht, daß an dem vom Lagerbolzen abgewandten Ende des Winkelschenkels ein entlang der Längsschmalseite des Ausstellarms erstreckender Flansch angeordnet ist, der an seinem freien Ende eine gegen das Verstärkungsstück anliegende Nase aufweist und daß das Verstärkungsstück beidseitig mit je einem Steg versehen und die Nase in den fixierten Drehlagen zwischen einem Steg des Verstärkungsstücks und der gegenüberliegenden Unterseite des das Verstärkungsstück beidseitig überragenden Teils des Ausstellarms geführt ist, so daß Steg, Nase und Unterseite des Ausstellarms die Sicherungsmittel bilden.This is achieved in a generic display device in that a flange extending along the longitudinal narrow side of the extension arm is arranged at the end of the angled arm facing away from the bearing pin, which flange has a nose against the reinforcement piece at its free end and that the reinforcement piece has a web on both sides provided and the nose is guided in the fixed rotational positions between a web of the reinforcing piece and the opposite underside of the part of the extending arm projecting beyond the reinforcing piece, so that the web, nose and underside of the extending arm form the securing means.

Zufolge dieser Ausgestaltung wird eine zusätzliche Abstützstelle zur Kraftübertragung zwischen Ausstellarm und am Festrahmen zu befestigendem Lagerbock geschaffen. Diese zusätzliche Abstützstelle ist in größerem Abstand von dem Lagerbolzen angeordnet wie die Abstützstelle zwischen Achsbolzen und Winkelschenkel. Die drei Abstützstellen im Winkelstück, nämlich Lagerbolzen, Achsbolzen und Nase, liegen dabei in drei unterschiedlichen Ebenen, und zwar sowohl in Längsrichtung des Ausstellarms gesehen als auch in der Querrichtung dazu. Neben dieser Verbesserung der Abstützung, wodurch bei gleicher Bemessung größere Kräfte übertragen werden können, wirkt sich auch günstig aus, daß bei kippgeöffnetem Flügel durch die - senkrecht zur Fensterebene betrachtet - Hintereinanderanordnung der Abstützstellen, wobei die Abstützstelle Achsbolzen/Winkelstück die dazwischenliegende Abstützstelle darstellt, vorhandene Toleranzen innerhalb der mittleren Abstützstelle Achsbolzen/Winkelstück weitgehend aufgehoben werden, da durch die Belastung die Nase verstärkt gegen das Verstärkungsstück gedrückt wird.As a result of this configuration, an additional support point for power transmission between the extension arm and the bearing block to be fastened to the fixed frame is created. This additional support point is arranged at a greater distance from the bearing pin than the support point between the axle pin and the angle leg. The three support points in the elbow, namely bearing pin, axle pin and nose, lie in three different planes, both in the longitudinal direction of the extension arm and in the transverse direction. In addition to this improvement of the support, whereby larger forces can be transmitted with the same dimensioning, it also has a favorable effect that, when the sash is open, through the arrangement of the support points - viewed vertically to the window plane - one behind the other, the support point axle pin / angle piece being the intermediate support point Tolerances within the central support point of the axle pin / contra-angle are largely eliminated, as the nose presses against the reinforcement piece due to the load.

Da das Verstärkungsstück schmäler ist als die Breite des Ausstellarms, liegt die Nase an der Unterseite des Ausstellarms an. Bei einer Drehung des Winkelstücks um den Achsbolzen ist die Bewegung damit auf eine 180°-Drehung automatisch beschränkt. Unter Belastung liegt die Nase zwischen Ausstellarm und Steg des Verstärkungsstücks. Die Sicherungsmittel sind damit vom Achsbolzen und dem Winkelstück in den Bereich des Verstärkungsstücks hinein wegverlegt, so daß der Achsbolzen für konstruktive Weiterausgestaltungen freigegeben ist.Since the reinforcement piece is narrower than the width of the extension arm, the nose lies on the underside of the extension arm at. When the contra-angle handpiece is rotated around the axle bolt, the movement is automatically limited to a 180 ° rotation. Under load, the nose lies between the extension arm and the web of the reinforcement piece. The securing means are thus moved away from the axle bolt and the angle piece into the area of the reinforcement piece, so that the axle bolt is released for further constructional developments.

Es ist günstig, daß der Flansch gegenüber der Längsschmalseite des Ausstellarms in Richtung auf das Verstärkungsstück zu leicht geneigt ausgebildet ist und die Nase unter Vorspannung an dem Verstärkungsstück anliegend ist.It is favorable that the flange is designed to be slightly inclined relative to the longitudinal narrow side of the extension arm in the direction of the reinforcement piece and that the nose bears against the reinforcement piece under prestress.

Dadurch wird erreicht, daß in belastetem Zustand der Ausstellvorrichtung infolge der Vorspannung zwischen Nase und Achsbolzen das vorhandene Spiel zwischen Achsbolzen und Winkelstück durch eine leichte Schrägstellung des Winkelstücks zum Achsbolzen unschädlich gemacht wird und dabei dann der Flansch parallel zur Längsschmalseite des Ausstellarms ausgerichtet ist.This ensures that the existing play between the axle pin and angle piece is made harmless in the loaded state of the opening device due to the pretension between the nose and axle pin by a slight inclination of the angle piece to the axle pin and then the flange is aligned parallel to the longitudinal narrow side of the extension arm.

In vorteilhafter Weise ist die zum Zusammenwirken mit einer Seitenfläche des Verstärkungsstücks dienende Anlagefläche der Nase ballig ausgebildet und das Verstärkungsstück anschließend an die Stege jeweils mit einer Schrägfläche versehen. Diese Ausgestaltung erlaubt bei einem Drehen des Winkelstücks um den Achsbolzen zur Links-/Rechtsumstellung ein enges Vorbeilaufen der Nase an dem Verstärkungsstück und damit eine Anlage der Nase in der Enddrehlage an einer Seitenfläche des Verstärkungsstücks.Advantageously, the contact surface of the nose serving to cooperate with a side surface of the reinforcement piece is spherical and the reinforcement piece is subsequently provided with an inclined surface on the webs. This configuration allows the nose to run closely past the reinforcing piece when the angle piece is rotated about the axle bolt for left / right changeover and thus allows the nose to rest in the end rotational position on a side face of the reinforcing piece.

Der Kopf des Achsbolzens ist in bevorzugter Weise als Senkkopf ausgebildet, so daß er in belastetem Zustand der Ausstellvorrichtung nicht über den Winkelschenkel störend vorsteht.The head of the axle bolt is preferably designed as a countersunk head, so that it is in the loaded state Display device does not protrude over the angle leg.

Gemäß einer besonders zweckmäßigen Ausgestaltung ist der Achsbolzen von einer in eine Gewindebohrung des Verstärkungsstücks eingedrehten Schraube mit im Bereich des Winkelschenkels glattem Schaft und am Kopf angeordnetem Betätigungsangriff gebildet, so daß der Achsbolzen die Funktion der Verstellung des wirksamen Abstands zwischen Ausstellarm und Winkelstück übernehmen kann, ohne daß die Links/Rechtsumstellbarkeit davon beeinträchtigt wird. Der glatte Schaft befindet sich bei belastetem Zustand der Ausstellvorrichtung im Bereich der Bohrung des Winkelschenkels und der Kopf ist insbesondere mit einem Innensechskant als Betätigungsangriff versehen, über den die Verstellung der den Achsbolzen bildenden Schraube erfolgt.According to a particularly expedient embodiment, the axle bolt is a screw that is screwed into a threaded bore of the reinforcement piece and has a shaft that is smooth in the region of the angle leg and is arranged on the head Actuating attack formed so that the axle bolt can take over the function of adjusting the effective distance between the raising arm and the contra-angle handpiece, without the left / right changeability being impaired thereby. When the opening device is loaded, the smooth shaft is located in the area of the bore of the angled leg and the head is in particular provided with an internal hexagon as an actuating attack by means of which the screw forming the axle bolt is adjusted.

Um das drehlagerseitige Ende des Ausstellarms zu versteifen, ist es mit einer Abbiegung versehen, an welche die Stege des Verstärkungsstücks angrenzen. Diese Abbiegung bildet gleichzeitig noch einen Anschlag für die Nase des Winkelstücks und begrenzt dabei die Verstellnöglichkeit zwischen Winkelstück und Ausstellarm.In order to stiffen the end of the pivot arm on the pivot bearing, it is provided with a bend against which the webs of the reinforcement piece adjoin. This bend also forms a stop for the nose of the contra-angle and limits the possibility of adjustment between the contra-angle and the extension arm.

Da der Ausstellarm mit einem Langloch versehen ist, in dem formschlüssig eine Wulst des Verstärkungsstücks gelagert ist, ist das Verstärkungsstück leicht zu montieren und zentriert sich zwangsläufig durch das Eingreifen seines keilförmigen Wulstes unter Formschluß in das Langloch des Ausstellarms. Dabei kann die Abbiegung des Ausstellarms als weitere Abstützung und Anlage für das Verstärkungsstück benutzt werden.Since the extension arm is provided with an elongated hole in which a bead of the reinforcement piece is positively mounted, the reinforcement piece is easy to assemble and is inevitably centered by the engagement of its wedge-shaped bead with a positive fit in the elongated hole of the deployment arm. The bend of the extension arm can be used as additional support and system for the reinforcement piece.

Eine besonders günstige Ausgestaltungsform liegt darin, daß der Abstand der Nase von der Stirnfläche des Flansches in etwa der Stärke des Ausstellarms entspricht. Dadurch wird eine niedrige Bauhöhe des Flansches und damit des Winkelstücks erhalten. Der Flansch ragt nicht über die obere Breitseite des Ausstellarms hinaus. Nach unten hin steht er nicht über die Stärke des Verstärkungsstücks vor, so daß durch den Flansch sich keinerlei zusätzlicher Platzbedarf für das Winkelstück in der Höhe ergibt.A particularly favorable embodiment is that the distance of the nose from the end face of the flange corresponds approximately to the strength of the extension arm. This results in a low overall height of the flange and thus of the contra-angle. The flange does not protrude beyond the upper broad side of the extension arm. At the bottom, it does not protrude beyond the strength of the reinforcement piece, so that the flange does not require any additional space in height for the angle piece.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird nachfolgend näher erläutert.An embodiment of the invention is shown in the drawings and is explained in more detail below.

Die Ausstellvorrichtung besteht im wesentlichen aus einem Ausstellarm 1 flachrechteckigen Querschnitts, der einerends schiebbar an einem Flügel zu befestigen ist und anderenends in einem am Festrahmen zu verschraubenden Lagerbock 2 drehbar gelagert ist. Zwischen Augen 3 des Lagerbocks 2 befindet sich ein Winkelstück 4, das drehbar im Lagerbock 2 gehalten ist mittels eines die Augen 3 und den Augenteil 6 des Winkelstücks 4 durchsetzenden Lagerbolzens 5.The opening device essentially consists of an opening arm 1 with a flat rectangular cross section, which can be slidably attached to a wing at one end and is rotatably mounted at the other end in a bearing block 2 to be screwed to the fixed frame. Between the eyes 3 of the bearing block 2 there is an angle piece 4 which is rotatably held in the bearing block 2 by means of a bearing pin 5 passing through the eyes 3 and the eye part 6 of the angle piece 4.

Das Winkelstück 4 besitzt im wesentlichen eine Z-Form. Der mit dem Augenteil 6 versehene Winkelsteg 7 ist in am Festrahmen montierter Stellung vor der Sichtfläche des Festrahmens angeordnet. Daran schließt sich im rechten Winkel ein mit einer glatten Durchgangsbohrung 8 versehener Winkelschenkel 9 an. Die Bohrung 8 des Winkelschenkels 9 weist auf ihrer vom Ausstellarm 1 abgewandten Seite eine Senkung 10 auf. An den Winkelschenkel 9 schließt sich ein Flansch 11 an, der sich entlang der Längsschmalseite 12 des Ausstellarms 1 erstreckt und an seinem freien Ende eine Nase 13 mit ballig ausgestalteter Anlagefläche 14 trägt.The angle piece 4 essentially has a Z shape. The angular web 7 provided with the eye part 6 is arranged in the position mounted on the fixed frame in front of the visible surface of the fixed frame. This is followed at right angles by an angled leg 9 provided with a smooth through bore 8. The bore 8 of the angle leg 9 has a countersink 10 on its side facing away from the extension arm 1. A flange 11 adjoins the angle leg 9, which flange extends along the longitudinal narrow side 12 of the extension arm 1 and carries at its free end a lug 13 with a spherically shaped contact surface 14.

An der Unterseite 15 des Ausstellarms 1 ist ein Verstärkungsstück 16 befestigt, das mit einer Wulst 17 formschlüssig in ein Langloch 18 nahe des drehlagerseitigen Endes des Ausstellarms 1 eingreift und dabei mit einer Stirnfläche an einer Abbiegung 19 des Ausstellarms 1 anliegt. Angrenzend an die Abbiegung 19 sind am Verstärkungsstück 16 zwei Stege 20 angeformt, an die sich jeweils eine Schrägfläche 21 anschließt. In einer zentrischen Gewindebohrung 22 des Verstärkungsstücks 16 ist als Achsbolzen 23 eine mit einem Senkkopf 24 und einem glatten Schaft 25 versehene Schraube eingedreht, wobei der Schaft 25 sich innerhalb der Durchgangsbohrung 8 des Winkelschenkels 9 befindet und der mit einem Innensechskant als Betätigungseingriff 26 ausgestattete Senkkopf 24, den Winkelschenkel 9 hintergreifend, innerhalb der Senkung 10. Insbesondere Fig. 3 ist zu entnehmen, daß in der gekuppelten Stellung von Winkelstück 4 und Ausstellarm 1 die Nase 13 geführt ist durch die Unterseite 15 des Ausstellarms 1 und durch den Steg 20. Dabei liegt die ballige Anlagefläche 14 der Nase 13 unter Vorspannung an der Seitenfläche 28 des Verstärkungsstücks 16 an.On the underside 15 of the extension arm 1, a reinforcement piece 16 is fastened, which engages with a bead 17 in a form-fitting manner in an elongated hole 18 near the end of the extension arm 1 on the pivot bearing side and abuts against a bend 19 of the extension arm 1 with an end face. Adjacent to the bend 19, two webs 20 are formed on the reinforcement piece 16, each of which is adjoined by an inclined surface 21. In a central threaded bore 22 of the reinforcing piece 16, a screw provided with a countersunk head 24 and a smooth shaft 25 is screwed in as the axle bolt 23, the shaft 25 being located within the through bore 8 of the angled leg 9 and the countersunk head 24 equipped with an internal hexagon as the actuating engagement 26 , behind the angle leg 9, within the depression 10. In particular, FIG. 3 shows that, in the coupled position of the angle piece 4 and the extension arm 1, the nose 13 is guided through the underside 15 of the extension arm 1 and through the web 20 the spherical contact surface 14 of the nose 13 under prestress on the side surface 28 of the reinforcing piece 16.

In Fig. 1 ist die Ausstellvorrichtung für einen Rechtsanschlag bestimmt dargestellt, wobei die Fixierung dieser End-Drehlage gegen ein ungewolltes Verdrehen gegeben ist durch den Eingriff der Nase 13 zwischen Ausstellarm 1 und Steg 20. Um die Ausstellvorrichtung auf einen Linksanschlag umzustellen, sind Ausstellarm 1 und Winkelstück 4 gegeneinander zu verschieben. Dabei gleitet das Winkelstück 4 entlang dem Achsbolzen 23 und die Nase 13 entlang der Seitenfläche 28 des Verstärkungsstücks 16. Kurz bevor der Winkelschenkel 9 zur Anlage an der Abbiegung 19 des Ausstellarms 1 gelangt, hat die Nase 13 des Flansches 11 den Bereich des Steges 20 verlassen. Das Winkelstück 4 kann nunmehr um den Achsbolzen 23 gedreht werden. Diese Drehbewegung wird nach 180° gestoppt durch das Anschlagen der Nase 13 an der Unterseite 15 des Ausstellarms 1 auf der anderen Seite des Verstärkungsstücks 16. Abschließend sind Ausstellarm 1 und Winkelstück 4 wieder voneinander weg zu bewegen, bis das Winkelstück 4 am Kopf 24 des Bolzens 23 zum Anschlag gelangt, wobei die Nase 13 wiederum gegen ein Drehen gesichert zwischen Ausstellarm 1 und Steg 20 geführt ist. Wie insbesondere Fig. 3 zu entnehmen ist, ist der Abstand zwischen der Nase 13 und der benachbarten Stirnfläche 27 des Flansches 11 geringer als die Stärke des Ausstellarms 1, so daß in beiden Drehendlagen die Stirnfläche 27 gegenüber der Oberseite des Ausstellarms 1 zurückstehend angeordnet ist. Ein zusätzlicher Platzbedarf für das Winkelstück 4 in Richtung der Falzhöhe des Fensters ist nicht erforderlich.In Fig. 1, the opening device is shown intended for a right-hand stop, the fixing of this end rotational position against inadvertent rotation being provided by the engagement of the nose 13 between the opening arm 1 and the web 20. In order to convert the opening device to a left-hand stop, the opening arm 1 and move elbow 4 against each other. The elbow 4 slides along the axle pin 23 and the lug 13 along the side surface 28 of the reinforcing piece 16. Shortly before the elbow leg 9 comes to rest against the bend 19 of the extension arm 1, the lug 13 of the flange 11 has left the area of the web 20 . The angle piece 4 can now be rotated about the axle pin 23. This rotary movement is stopped after 180 ° by striking the nose 13 on the underside 15 of the extension arm 1 the other side of the reinforcing piece 16. Finally, the raising arm 1 and the angle piece 4 are to be moved away from one another again until the angle piece 4 comes to a stop at the head 24 of the bolt 23, the nose 13 in turn being secured against rotation between the raising arm 1 and the web 20 is. As can be seen in particular in FIG. 3, the distance between the nose 13 and the adjacent end face 27 of the flange 11 is less than the thickness of the extension arm 1, so that the end surface 27 is arranged in a recessed manner in both rotational end positions relative to the top of the extension arm 1. An additional space requirement for the angle piece 4 in the direction of the rebate height of the window is not necessary.

Zum Anheben bzw. Absenken des Flügels unter Veränderung des Abstands zwischen der Abbiegung 19 des Ausstellarms 1 und dem Winkelschenkel 9 des Winkelstücks 4 ist die Achsbolzen-Schraube 23 weiter in die Gewindebohrung 22 des Verstärkungsstücks 16 hineinzudrehen bzw. weiter herauszubewegen. In belastetem Zustand der Ausstellvorrichtung, also bei am Fenster angeschlagener Ausstellvorrichtung, bewirkt das Flügelgewicht, daß der Senkkopf 24 des Achsbolzens 23 stets in der Senkung 10 des Winkelschenkels 9 anliegt und gehalten ist. Die durch das Flügelgewicht bewirkten Kräfte bedingen auch ein um die Anlenkstelle Achsbolzen 23/Durchgangsbohrung 8 des Winkelschenkels 9 wirkendes Moment, durch das die Nase 13 gegen die Seitenfläche 28 des Verstärkungsstücks 16 gedrückt wird.To raise or lower the wing while changing the distance between the bend 19 of the extension arm 1 and the angle leg 9 of the angle piece 4, the axle bolt screw 23 must be screwed further into the threaded bore 22 of the reinforcement piece 16 or moved further out. In the loaded state of the opening device, that is to say when the opening device is attached to the window, the sash weight causes the countersunk head 24 of the axle pin 23 to always rest and be held in the depression 10 of the angle leg 9. The forces caused by the sash weight also cause a moment acting around the pivot pin 23 / through bore 8 of the angled leg 9, by which the nose 13 is pressed against the side surface 28 of the reinforcing piece 16.
