Description

Die Erfindung geht von einer Ausstellvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1 aus.The invention is based on an opening device according to the preamble of claim 1.

Bei derartigen Ausstellvorrichtungen dient die Trennbarkeit zwischen Ausstellarm und Flügelteil des Schwenklagers zur Ermöglichung einer Umstellung der Anschlagrichtung in rechts auf links bzw. umgekehrt und gestattet eine Vereinfachung, da Ausstellarme unterschiedlicher Länge wahlweise mit dem Flügelteil verbindbar sind bzw. der Ausstellarm auswechselbar am Schwenklager gelagert ist. Der zur Befestigung am Befestigungslappen flächig anliegende Schenkel des Ausstellarms wird von einer Abbiegung des Ausstellarms selbst gebildet oder von einem Winkelschenkel eines am Ausstellarm angebrachten Winkelstücks. Die Befestigung zwischen dem abgewinkelten Schenkel des Ausstellarms und dem Befestigungslappen des Flügelteils erfolgt üblicherweise mittels Schrauben. Die Schrauben sind dabei zusätzlich zu sichern, da bei am Fenster angeschlagener Ausstellvorrichtung bei Betätigung des Fensters eine in Achsrichtung der Schrauben auf die Schrauben einwirkende Wechselbelastung auftreten kann, die zu einem Lockern oder gar Lösen der Schrauben führt.In the case of such opening devices, the separability between the opening arm and the wing part of the pivot bearing serves to make it possible to change the stop direction from right to left or vice versa and permits simplification, since opening arms of different lengths can optionally be connected to the wing part or the opening arm is exchangeably mounted on the pivot bearing. The leg of the extension arm that lies flat against the fastening tab is formed by a bend in the extension arm itself or by an angle leg of an angle piece attached to the extension arm. The attachment between the angled leg of the extension arm and the fastening tab of the wing part is usually carried out by means of screws. The screws must be additionally secured, since when the opening device is attached to the window when the window is actuated, an alternating load acting on the screws in the axial direction can occur, which leads to loosening or even loosening of the screws.

Zur Verbesserung der Kraftaufnahme zwischen dem abgewinkelten Schenkel des Ausstellarms und dem Flügelteil des Schwenklagers ist es aus der DE-OS 3 402 617 bekannt, auf der der Hülse des Flügelteils zugewandten Fläche des Befestigungslappens eine hinterschnittene Nut auszubilden, in welche der abgewinkelte Schenkel formschlüssig einschiebbar ist. Die den Schenkel des Ausstellarms hintergreifenden Übergriffsstege der Nut des Flügelteils verhindern ein Abheben des Schenkels vom Befestigungslappen auch bei starker Belastung. Damit die Verbindung sich nicht in Einschieberichtung lösen kann, wird als Sicherungselement eine Druckverspannung angewendet. Dies bedeutet, daß die Abmessungen des lichten Querschnitts der Nut und des Querschnitts des abgewinkelten Schenkels des Ausstellarms eng aneinander angepaßt sein müssen, was zum einen einen verstärkten Fertigungsaufwand bedingt und zum anderen insbesondere das Einbringen des Schenkels in die hinterschnittene Nut sehr erschwert. Auch ist das Lösen der Verbindung dadurch behindert, daß die Art der Sicherung dieser Verbindung gegen ein Lösen für den Fachmann nicht erkennbar ist.To improve the force absorption between the angled leg of the extension arm and the wing part of the pivot bearing, it is known from DE-OS 3 402 617 to form an undercut groove on the surface of the fastening tab facing the sleeve of the wing part, into which the angled leg can be inserted in a form-fitting manner . The overlapping webs behind the leg of the opening arm of the groove of the wing part prevent the leg from being lifted off the fastening tab even under heavy loads. So that the connection cannot come loose in the insertion direction, is used as Securing element applied a compressive stress. This means that the dimensions of the clear cross-section of the groove and the cross-section of the angled leg of the extension arm must be closely matched to one another, which on the one hand necessitates an increased manufacturing outlay and on the other hand very difficult the insertion of the leg into the undercut groove. The loosening of the connection is also hampered by the fact that the type of securing this connection against loosening is not recognizable to the person skilled in the art.

Die Aufgabe der Erfindung besteht nunmehr darin, bei einer gattungsgemäßen Ausstellvorrichtung mit schraubenloser Befestigung des abgewinkelten Schenkels des Ausstellarms in einer hinterschnittenen Nut des Befestigungslappens des Flügelteils des Schwenklagers die Montage und Demontage bei verbesserter Handhabung zu erleichtern.The object of the invention is now to facilitate assembly and disassembly with improved handling in a generic raising device with screwless fastening of the angled leg of the raising arm in an undercut groove of the fastening tab of the wing part of the pivot bearing.

Die erfindungsgemäße Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Patentanspruchs 1.The achievement of this object results from the characterizing features of claim 1.

Das Sicherungselement wird von einer auf dem abgewinkelten Schenkel des Ausstellarms aufliegenden Blattfeder gebildet, die an ihrem freien Ende mindestens eine Nase aufweist, die eine Sicherungskante des Befestigungslappens hintergreift. Das Sicherungselement ist damit sichtbar und die Bedienungsperson kann dessen Funktion ohne weitere Information erkennen und damit das Sicherungselement betätigen. Um die Verbindung zu lösen, ist die Nase aus dem Hintergriff mit der Sicherungskante durch Anheben des mit der Nase versehenen Bereichs des Verlängerungsstücks der Blattfeder auszuheben. Dies kann ohne Werkzeug und gegen die Federkraft des überstehenden, abgebogenen Verlängerungsstücks der Blattfeder erfolgen.The securing element is formed by a leaf spring resting on the angled leg of the deployment arm, which has at its free end at least one nose which engages behind a securing edge of the fastening tab. The securing element is thus visible and the operator can recognize its function without further information and thus operate the securing element. To release the connection, the nose must be lifted out of the rear grip with the securing edge by lifting the area of the extension piece of the leaf spring provided with the nose. This can be done without tools and against the spring force of the protruding, bent extension piece of the leaf spring.

Bei entsicherter Nase ist der abgewinkelte Schenkel des Ausstellarms entgegen der Einschieberichtung aus der hinterschnittenen Nut des Befestigungslappens nur wenig zu verschieben. Die Nase kann dann losgelassen werden und gelangt unter Vorspannung zur Auflage auf den Übergriffsstegen der Nut und bildet dann gegen die Trennung von Flügelteil und Ausstellarm keinen großen Widerstand mehr.When the nose is unlocked, the angled leg of the extension arm can only be moved slightly out of the undercut groove of the fastening tab against the direction of insertion. The nose can then be released and comes under pretension to rest on the overlapping webs of the groove and then no longer forms a great resistance to the separation of the wing part and extension arm.

Das überstehende Verlängerungsstück der Blattfeder vereinfacht den Zusammenbau von Flügelteil und Ausstellarm. Zu diesem Zweck wird das federnde Verlängerungsstück zur Auflage auf den Übergriffsstegen der hinterschnittenen Nut aufgesetzt, wobei das freie Ende des abgewinkelten Schenkels des Ausstellarms im Abstand von der Stirnfläche des Befestigungslappens angeordnet ist. Durch einen Druck auf den Befestigungslappen hebt das Verlängerungsstück vom Ausstellarm ab, die Nut gelangt in den Bereich des Querschnitts des freien Endes des abgewinkelten Ausstellarmschenkels und der Ausstellarm kann nunmehr in die Nut eingeschoben werden. Sobald die Nase die Sicherungskante des Befestigungslappens passiert hat, schnappt die Nase infolge der Vorspannung des Verlängsrungsstücks hinter die Sicherungskante. Damit ist die Einschiebebewegung beendet und der Ausstellarm gegen ein Ausschieben und Lösen gesichert.The protruding extension of the leaf spring simplifies the assembly of the wing part and extension arm. For this purpose, the resilient extension piece is placed on the overlapping webs of the undercut groove, the free end of the angled leg of the extension arm being arranged at a distance from the end face of the fastening tab. By pressing the mounting tab, the extension piece lifts off the extension arm, the groove reaches the area of the cross section of the free end of the angled extension arm leg, and the extension arm can now be inserted into the groove. As soon as the nose has passed the securing edge of the fastening tab, the nose snaps behind the securing edge due to the pretensioning of the extension piece. This completes the insertion movement and the extension arm is secured against being pushed out and released.

In bevorzugter Weise wird die Sicherungskante von der der Einführrichtung des Schenkels gegenüberliegenden Stirnfläche des Befestigungslappens gebildet, so daß die Erstellung der Sicherungskante keine zusätzliche Bearbeitung bedingt.The securing edge is preferably formed by the end face of the fastening tab opposite the insertion direction of the leg, so that the creation of the securing edge does not require any additional processing.

Um ein Überstehen der Nase über den Befestigungslappen hinaus in gesicherter Stellung zu vermeiden, kann die Sicherungskante von mindestens einer Ausnehmung im Grundsteg und/oder der Übergriffsstege der Nut des Befestigungslappens gebildet werden, so daß die Nase vom Querschnitt des Befestigungslappens des Flügelteils des Schwenklagers aufgenommen ist.In order to prevent the nose from protruding beyond the fastening tab in a secured position, the securing edge can have at least one recess in the base web and / or the overlapping webs of the groove of the mounting tab are formed so that the nose is received by the cross section of the fastening tab of the wing part of the pivot bearing.

Es ist günstig, die Nase in der Ebene des Verlängerungsstücks anzuordnen, so daß die Blattfeder mittels eines Stanzvorgangs herstellbar ist.It is advantageous to arrange the nose in the plane of the extension piece, so that the leaf spring can be produced by means of a stamping process.

Die Blattfeder kann gleichzeitig zur Begrenzung der Einschiebebewegung des abgewinkelten Schenkels des Ausstellarms in die Nut des Befestigungslappens benutzt werden, indem die Blattfeder zum Anschlag an der in Einschieberichtung angeordneten Stirnfläche des Befestigungslappens mit mindestens einem Vorsprung versehen ist.The leaf spring can at the same time be used to limit the insertion movement of the angled leg of the extension arm into the groove of the fastening tab, in that the leaf spring is provided with at least one projection for abutment on the end face of the fastening tab arranged in the insertion direction.

Besonders bevorzugt wird es, daß die Breite der Blattfeder im wesentlichen der Breite der Öffnung der Nut des Befestigungslappens entspricht, daß die Blattfeder an einem Ende mit mindestens einem Vorsprung und am anderen Ende mit mindestens einer Nase versehen ist, wobei der Abstand zwischen Vorsprung und Nase an die Länge des Befestigungslappens angepaßt ist.It is particularly preferred that the width of the leaf spring substantially corresponds to the width of the opening of the groove of the fastening tab, that the leaf spring is provided at one end with at least one projection and at the other end with at least one nose, the distance between the projection and the nose is adapted to the length of the mounting tab.

Two embodiments of the invention are shown in the drawing and explained in more detail below. Show it:
Fig. 1
in a diagrammatic exploded view, an opening device in the area of the pivot bearing and
Fig. 2

Die Ausstellvorrichtung ist für einen Drehkippflügel bestimmt. Der Ausstellarm 1 befindet sich bei am Fenster angeschlagenem Zustand und bei geschlossenem Flügel verdeckt im Falz zwischen Flügel und Blendrahmen und das blendrahmenseitige Ende des Ausstellarms 1 ist zu einem abgewinkelten Schenkel 2 um 90° nach unten abgebogen. Der Schenkel 2 ist mit einem Schwenklager 3 zu kuppeln, das aus einem am Blendrahmen zu befestigenden Lagerbock 4 und einem Flügelteil 5 besteht, die mittels eines die Augen 6 des Lagerbocks 4 und die Hülse 7 des Flügelteils 5 durchsetzenden Gelenkbolzens 8 schwenkbar verbunden sind. An die Hülse 7 schließt sich ein Befestigungslappen 9 an, der eine hinterschnittene Nut 10 mit T-förmigem Querschnitt besitzt, deren Öffnung 11 von zwei Übergriffsstegen 12 begrenzt ist.The opening device is designed for a tilt and turn sash. The extension arm 1 is in the hinged state on the window and, when the sash is closed, is concealed in the fold between the sash and the frame and the end of the extension arm 1 on the frame side is bent downward to form an angled leg 2 by 90 °. The leg 2 is to be coupled to a pivot bearing 3, which consists of a bracket 4 to be fastened to the frame and a wing part 5 which are pivotally connected by means of an articulation bolt 8 passing through the eyes 6 of the bearing block 4 and the sleeve 7 of the wing part 5. The sleeve 7 is followed by a fastening tab 9, which has an undercut groove 10 with a T-shaped cross section, the opening 11 of which is delimited by two overlapping webs 12.

Das Flügelteil 5 ist von einem Strangpreßprofil aus einer Aluminiumlegierung abgelängt, wobei die Hülse 7 kürzer ausgebildet ist als die Länge des Befestigungslappens 9. Zur Ermöglichung einer Links-/Rechtsanwendung ist der Befestigungslappen 9 zu einer horizontalen Querebene symmetrisch gestaltet. Die im Querschnitt T-förmige Nut 10 ist durch den Grundsteg 13, die Seitenstege 14 und die Übergriffsstege 12 bestimmt, wobei der lichte Querschnitt der Nut 10 und der Querschnitt des flachrechteckigen Schenkels 2 in etwa aneinander angepaßt sind.The wing part 5 is cut to length from an extruded profile made of an aluminum alloy, the sleeve 7 being shorter than the length of the fastening tab 9. To enable left / right use, the fastening tab 9 is designed symmetrically to a horizontal transverse plane. The cross-sectionally T-shaped groove 10 is determined by the base web 13, the side webs 14 and the overlap webs 12, the clear cross-section of the groove 10 and the cross-section of the flat-rectangular leg 2 being approximately matched to one another.

Am abgebogenen Schenkel 2 des Ausstellarms 1 ist ein als Blattfeder 15 ausgestaltetes Sicherungselement mittels Nieten 16 befestigt und die Blattfeder 15 weist eine Breite auf, die etwas kleiner ist als die Breite der Öffnung 11 der Nut 10. Das über das freie Ende 17 des Schenkels 2 hinausragende Verlängerungsstück 18 ist in Richtung auf die gegenüberliegende Breitseite des Schenkels 2 und im Endbereich wieder parallel zum Schenkel 2 abgebogen, wo sich in der Ebene der Blattfeder 15 zwei Nasen 19 seitlich erstrecken. Am gegenüberliegenden Ende der Blattfeder 15 befinden sich gleichgeformte Vorsprünge 20. Die Blattfeder 15 ist zu einer Längsebene symmetrisch ausgestaltet.A securing element designed as a leaf spring 15 is fastened to the bent leg 2 of the extension arm 1 by means of rivets 16 and the leaf spring 15 has a width which is slightly smaller than the width of the opening 11 of the groove 10. This is via the free end 17 of the leg 2 protruding extension piece 18 is bent in the direction of the opposite broad side of the leg 2 and in the end region again parallel to the leg 2, where there are two in the plane of the leaf spring 15 Extend lugs 19 laterally. At the opposite end of the leaf spring 15 there are projections 20 of the same shape. The leaf spring 15 is configured symmetrically to a longitudinal plane.

Zum Kuppeln des Ausstellarms 1 mit dem Flügelteil 5 des Schwenklagers 3 ist zuerst die Blattfeder 15 mit ihren Nasen 19 zur Auflage auf den Übergriffsstegen 12 des Befestigungslappens 9 zu bringen, wobei sich das freie Ende 17 des Schenkels 2 etwas oberhalb der oberen Stirnfläche 21 des Befestigungslappens 9 befindet. Durch Druckausübung zwischen Flügelteil 5 und Ausstellarm 1 hebt sich die Blattfeder 15 von dem Schenkel 2 ab. Sobald der Querschnitt des Schenkels 2 in den Bereich des lichten Querschnitts der Nut 10 gelangt ist, sind der Schenkel 2 und das Flügelteil 5 relativ zueinander aufeinanderzuzuschieben und der Schenkel 2 gelangt in Eingriff mit dem Befestigungslappen 9. Nunmehr sind die beiden Bauteile 2 und 5 unter Vorspannung miteinander verbunden und können bequem weiter ineinander verschoben werden. Diese Verschiebebewegung ist abgeschlossen, sobald die Nasen 19 federnd hinter die untere Stirnfläche 22 des Befestigungslappens 9 einschnappen. Gleichzeitig sind die Vorsprünge 20, welche dieselbe Konfiguration wie die Nasen 19 besitzen, an der oberen Stirnfläche 21 zur Anlage gelangt und begrenzen damit die Einschiebebewegung. Der Abstand zwischen den Vorsprüngen 20 und den Nasen 19 entspricht der Länge des Befestigungslappens 9.To couple the extension arm 1 to the wing part 5 of the pivot bearing 3, the leaf spring 15 with its lugs 19 must first be brought to rest on the overlap webs 12 of the fastening tab 9, the free end 17 of the leg 2 being located somewhat above the upper end face 21 of the fastening tab 9 is located. By exerting pressure between the wing part 5 and the raising arm 1, the leaf spring 15 lifts off the leg 2. As soon as the cross section of the leg 2 has reached the area of the clear cross section of the groove 10, the leg 2 and the wing part 5 are to be pushed relative to one another and the leg 2 comes into engagement with the fastening tab 9. Now the two components 2 and 5 are under Preload connected and can be easily moved into each other. This shifting movement is completed as soon as the lugs 19 snap in behind the lower end face 22 of the fastening tab 9. At the same time, the projections 20, which have the same configuration as the lugs 19, come to bear on the upper end face 21 and thus limit the insertion movement. The distance between the projections 20 and the lugs 19 corresponds to the length of the fastening tab 9.

Das Flügelteil 5 ist damit mit dem Ausstellarm 1 zuverlässig verbunden und die Blattfeder 15 sichert die Verbindung in beiden Richtungen durch das Umgreifen sowohl mittels der Vorsprünge 20 als auch mittels der Nasen 19.The wing part 5 is thus reliably connected to the extension arm 1 and the leaf spring 15 secures the connection in both directions by reaching around both by means of the projections 20 and by means of the lugs 19.

Das Maß der Abbiegung des Verlängerungsstücks 18 in Richtung auf den Grundsteg 13 der Nut 10 ist derart bemessen, daß in gekuppeltem Zustand das Verlängerungsstück 18 mit spürbarer Vorspannung an dem Grundsteg 13 zur Auflage gelangt. Die Vorspannung kann sowohl durch die Wahl des Materials für die Blattfeder 15 beeinflußt werden als auch durch das Abstandsmaß der Nieten 16 von dem freien Ende 17 des Schenkels 2 des Ausstellarms 1.The extent of the deflection of the extension piece 18 in the direction of the base web 13 of the groove 10 is such that that in the coupled state the extension piece 18 comes to rest on the base web 13 with a noticeable prestress. The pretension can be influenced both by the choice of material for the leaf spring 15 and by the spacing of the rivets 16 from the free end 17 of the leg 2 of the extension arm 1.

Zum Entkuppeln der Bauteile 2 und 5 ist der über die als Sicherungskante 23 dienende untere Stirnfläche 22 des Befestigungslappens 9 vorstehende Bereich, der die Nasen 19 trägt, welche sich an der Stirnfläche 22 im Bereich der Seitenstege 14 abstützen, so weit anzuheben, daß die Nasen 19 nach einer kurzen Relativverschiebung zwischen Ausstellarm 1 und Flügelteil 5 auf den Übergriffsstegen 12 wieder zur Auflage gelangen. Durch eine weitere Relativverschiebung werden dann Ausstellarm 1 und Flügelteil 5 getrennt.To uncouple the components 2 and 5, the area above the lower end face 22 of the fastening tab 9, which serves as the securing edge 23 and which supports the lugs 19, which are supported on the end face 22 in the region of the side webs 14, has to be raised so far that the lugs 19 after a short relative displacement between the raising arm 1 and the wing part 5 on the overlaps 12 again come to rest. The extension arm 1 and wing part 5 are then separated by a further relative displacement.

Der abgewinkelte Schenkel 32 des Ausstellarms 31 der Fig. 2 ist unter Bildung einer Schulter 33 auf eine geringere Breite abgesetzt. Mittels Nieten 46 ist eine Blattfeder 45 auf dem Schenkel 32 befestigt, deren in Richtung auf die gegenüberliegende Fläche des Schenkels 32 abgewinkeltes, über das freie Ende 47 übergreifende Ende in der Ebene des Verlängerungsstücks 48 mit Nasen 49 versehen ist. Die Breite der Blattfeder 45 ist geringer als die Breite der Öffnung 41 der Nut 40 des Befestigungslappens 39 des Flügelteils 35, das wiederum zu einer horizontalen Querebene symmetrisch ausgestaltet ist.The angled leg 32 of the extension arm 31 of FIG. 2 is offset to a smaller width to form a shoulder 33. A leaf spring 45 is fastened on the leg 32 by means of rivets 46, the end of which, angled in the direction of the opposite surface of the leg 32, is provided with lugs 49 in the plane of the extension piece 48 over the free end 47. The width of the leaf spring 45 is less than the width of the opening 41 of the groove 40 of the fastening tab 39 of the wing part 35, which in turn is configured symmetrically to a horizontal transverse plane.

Das Flügelteil 35 ist zur Bildung von Sicherungskanten 38 nahe den Stirnflächen 51, 52 jeweils mit einem Paar von Ausnehmungen 50 versehen, durch das ein Teil der Seitenstege 44 und der Übergriffsstege 42 entfernt ist. An diese Ausnehmungen 50 sind die Abmessungen der Nasen 49 angepaßt. Der Grundsteg 43 weist eine längsverlaufende Vertiefung 34 auf.The wing part 35 is each provided with a pair of recesses 50 to form securing edges 38 near the end faces 51, 52, through which part of the side webs 44 and the overlap webs 42 is removed. The dimensions of the lugs 49 are at these recesses 50 customized. The base web 43 has a longitudinal recess 34.

Der Zusammenbau des Ausstellarms 31 mit dem Flügelteil 35 erfolgt analog Fig. 1. Die Sicherungskante 38, hinter welche in der Endstellung die Nasen 49 der Blattfeder 45 schnappend einfedern, wird von der Stirnfläche 36 der Ausnehmung 50 gebildet. Die Schulter 33 des Schenkels 32 begrenzt dabei unter Anschlagen an die obere Stirnfläche 37 der Ausnehmung 50 die Einschiebebewegung.The assembly of the extension arm 31 with the wing part 35 takes place analogously to FIG. 1. The securing edge 38, behind which the lugs 49 of the leaf spring 45 snap in in the end position, is formed by the end face 36 of the recess 50. The shoulder 33 of the leg 32 limits the insertion movement by striking the upper end face 37 of the recess 50.

Die Vertiefung 34 in dem Grundsteg 43 erleichert das Untergreifen der Blattfeder 45 zum Anheben des Verlängerungsstücks 48 für ein eventuell notwendiges Lösen der Verbindung.The recess 34 in the base web 43 makes it easier to reach under the leaf spring 45 to raise the extension piece 48 for a possibly necessary loosening of the connection.

Die Sicherung des Haltes zwischen dem Schenkel 32 des Ausstellarms 31 und dem Flügelteil 35 kann zusätzlich oder auch allein durch eine an die Blattfeder 45 angeprägte Noppe 53 erfolgen, die mit einer Bohrung 54 im Grundsteg 43 des Befestigungslappens 39 zusammenwirkt, wie in Fig. 2 dargestellt.The securing of the hold between the leg 32 of the extension arm 31 and the wing part 35 can additionally or also take place solely by a knob 53 stamped on the leaf spring 45, which interacts with a bore 54 in the base web 43 of the fastening tab 39, as shown in FIG. 2 .
