Description

Gegenstand der Erfindung ist eine Ausstellvorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a display device according to the preamble of claim 1.

Aus der EP 0666 398 B1 und DE 40 40 233 A1 ist eine Ausstellvorrichtung für ein Fenster oder eine Tür bekannt geworden, die einen Ausstellarm aufweist, der einerends am Flügel schwenkbar und längsverschiebbar zu lagern und anderenends lösbar mit einem Schwenklager kuppelbar ist. Das Schwenklager besteht aus einem am Blendrahmen zu befestigenden Lagerbock und einem Flügelteil, das mit dem Lagerbock mittels eines eine Hülse des Flügelteils durchsetzenden Gelenkbolzens schwenkbar verbunden ist. An die Hülse schließt sich ein abgewinkelter Bandlappen an, dessen Befestigungslappen zur Kopplung mit einem in Richtung der Schwenkachse abgewinkelten Schenkel des Ausstellarms vorgesehen ist. Dazu weist in der EP 0 666 398 81 der Bandlappen eine Nut auf, in die der Schenkel des Ausstellarms eingeführt werden kann, so dass dieser in Längsrichtung des Ausstellarms formschlüssig aufgenommen ist. Um ein unerwünschtes Entweichen aus der Verbindung zu vermeiden, ist der Schenkel des Ausstellarms mit einer Blattfeder versehen, die so bemessen ist, dass sie den Befestigungslappen an einem Ende - im Bereich der Nut - hintergreift.From the EP 0666 398 B1 and DE 40 40 233 A1 is a Ausstellvorrichtung for a window or a door has become known, which has a stay, which is pivotally mounted at one end on the wing and longitudinally displaceable and the other end detachable with a pivot bearing is detachable. The pivot bearing consists of a frame to be fastened to the bearing block and a wing portion which is pivotally connected to the bearing block by means of a sleeve of the wing portion passing through hinge pin. The sleeve is adjoined by an angled hinge flap, the fastening tabs of which are provided for coupling to a leg of the extension arm which is angled in the direction of the pivot axis. For this purpose points in the EP 0 666 398 81 the hinge flap on a groove into which the leg of the stay can be introduced so that it is positively received in the longitudinal direction of the stay. In order to avoid undesired escape from the connection, the leg of the extension arm is provided with a leaf spring, which is dimensioned so that it engages behind the fastening tabs at one end - in the region of the groove.

In der DE 40 40 233 A1 weist der Bandlappen ein Rückhalteelement mit hammerförmigem Kopf auf, der in eine schlüssellochförmige Öffnung im Schenkel des Ausstellarms eingeführt werden kann. Nach Verdrehen um 90 Grad übergreift der hammerförmige Kopf die Ränder der schlüssellochförmigen Öffnung. In dieser Montageposition umgreift eine, auf den Schenkel des Ausstellarms aufgesetzte, Blattfeder mit einer Ausnehmung die Außenkontur des hammerförmigen Kopfes, um ein Rückstellen zu verhindern.In the DE 40 40 233 A1 For example, the hinge plate has a hammer-shaped head retention element that can be inserted into a keyhole-shaped opening in the leg of the extension arm. After twisting by 90 degrees, the hammer-shaped head engages over the edges of the keyhole-shaped opening. In this mounting position engages a, patch on the leg of the extension, leaf spring with a recess, the outer contour of the hammer-shaped head to prevent a reset.

Aus dem DE-GM 1 923 282 ist es ferner bekannt, einen Ausstellarm mit einem Scharnierteil über eine Renkverbindung miteinander zu verbinden. Der Ausstellarm weist dazu zwei im Abstand zueinander angeordnete Pilzzapfen auf, deren Lage abgestimmt ist mit zwei schlüssellochartigen Ausnehmungen an dem Scharnierteil. In die Erweiterungen der schlüssellochförmigen Ausnehmungen lassen sich die Pilzzapfen einführen, sodass die verbreiterten Köpfe nach einem Verschieben in die Funktionsstellung die Ränder des schmalen Abschnitts Ausnehmungen hintergreifen. Um auch hier ein unerwünschtes Verschieben aus der Funktionsstellung zu vermeiden ist eine Blattfeder vorgesehen, welche an dem Ausstellarm vorgesehen wird und welche bei der Montage des Scharnierteils zunächst durch dieses weggedrückt wird und nach dem Erreichen der Funktionsstellung eine Querkante des Scharnierteils hintergreift, so dass eine Bewegung in entgegengesetzter Richtung zur Montagerichtung gesperrt ist.From DE-GM 1 923 282 it is also known to connect a stay with a hinge part via a Renkverbindung each other. The extension arm has for this purpose two mutually spaced mushroom pin, whose position is matched with two keyhole-like recesses on the hinge part. In the extensions of the keyhole-shaped recesses, the mushroom pin can be inserted so that the widened heads engage behind the edges of the narrow portion recesses after moving into the functional position. In order to avoid unwanted displacement from the functional position, a leaf spring is provided here, which is provided on the extension arm and which is initially pushed away during assembly of the hinge part and after reaching the functional position engages behind a transverse edge of the hinge part, so that movement is locked in the opposite direction to the mounting direction.

Aufgabe der Erfindung ist es, eine möglichst einfache Verbindung des Ausstellarms und des Bandlappens zu erreichen, welche eine einfache Herstellung der beteiligten Bauteile zulässt.The object of the invention is to achieve the simplest possible connection of the extension arm and the hinge strap, which allows a simple production of the components involved.

Die Lösung dieser Aufgabe gelingt mit den Merkmalen des Anspruchs 1. Es wird auf diese Weise eine Herstellung des Bandlappens aus einem gezogenen Profilteil möglich, welches nur einer geringen Nacharbeit zur Unterbrechung des Steges bedarf. Der Ausstellarm ist nur mit einfach herzustellenden Ausnehmungen zu versehen. Die Anordnung der Blattfeder an dem Befestigungslappen erleichtert die Handhabung bei der Montage, da auf diese Weise nur das geringere Abmessungen aufweisende Flügelteil bewegt werden muss. Die mittige Anordnung gewährleistet dabei die Verwendung für nach links und nach rechts öffnenbare Flügel.The solution to this problem is achieved with the features of claim 1. It is in this way a production of the hinge from a drawn profile part possible, which requires only a little rework to interrupt the bridge. The extension arm is to be provided only with easy-to-produce recesses. The arrangement of the leaf spring on the mounting tab facilitates handling during assembly, since in this way only the smaller dimensions having wing part must be moved. The central arrangement ensures the use for left and right openable wings.

Es ist ferner vorgesehen, dass der Steg mittels einer Bohrung durchbrochen wird. Dadurch wird in einem Arbeitsgang eine hinreichend große Unterbrechung des Steges, die darüber hinaus auch sehr einfach und maßhaltig ausgeführt werden kann.It is further provided that the web is broken by means of a bore. As a result, in a single operation a sufficiently large interruption of the web, which can also be carried out very easily and dimensionally stable.

Um eine Schwächung des Befestigungslappens zu vermeiden ist es von Vorteil, wenn die Bohrung als zylindrische Ausnehmung an dem Befestigungslappen ausgeführt ist. Dies kann beispielsweise mittels eines Schaftfräsers erreicht werden.In order to avoid a weakening of the fastening tab, it is advantageous if the bore is designed as a cylindrical recess on the fastening tab. This can be achieved, for example, by means of an end mill.

Es kann auch vorgesehen werden, dass die Blattfeder abschnittsweise in der Bohrung aufgenommen ist und zumindest bereichsweise einen annähernd kreisförmigen und an die Bohrung angepassten Umfang hat. Dadurch ist die Blattfeder bereits in Längsrichtung des Steges festgelegt.It can also be provided that the leaf spring is partially received in the bore and at least partially has an approximately circular and adapted to the bore circumference. As a result, the leaf spring is already fixed in the longitudinal direction of the web.

Die Befestigung der Blattfeder kann noch dadurch verbessert werden, dass die Blattfeder einen abgewinkelten Steg aufweist, der an dem Befestigungslappen seitlich anliegt. Hierdurch ergibt sich eine Montageerleichterung, da die Blattfeder auch in dieser Richtung eine definierte Ausrichtung relativ zum Befestigungslappen erhält.The attachment of the leaf spring can be further improved by the fact that the leaf spring has an angled web which bears laterally against the fastening tab. This results in a simplification of assembly, since the leaf spring receives a defined orientation relative to the mounting tabs in this direction.

Zur unverlierbaren Befestigung der Blattfeder kann ferner vorgesehen werden, dass der Befestigungslappen einen parallel zur Schwenklagerachse verlaufenden Absatz aufweist, an dem die Blattfeder zumindest bereichsweise anliegt. Dieser Absatz kann abschnittsweise verformt werden, so dass der verformte Teil die Blattfeder teilweise überlappt.For captive attachment of the leaf spring may further be provided that the fastening tab has a parallel to the pivot bearing axis extending shoulder on which the leaf spring rests at least partially. This paragraph may be deformed in sections, so that the deformed part of the leaf spring overlaps partially.

Um die Stabilität des abgewinkelten Schenkel des Ausstellarms zu erhalten ist vorgesehen, dass der Befestigungslappen eine randoffene und eine geschlossene Ausnehmung enthält, wobei die randoffene Ausnehmung als Schlitz ausgebildet ist und die geschlossene Ausnehmung einen Schlitz mit einer Erweiterung zum Durchtritt eines der T-förmigen Stege enthält. Abweichend davon kann nämlich vorgesehen sein, dass zumindest eine der Ausnehmungen L-förmig und seitlich offen ist, so dass der Steg in die Ausnehmung seitlich am Schenkel eingeführt werden kann und durch längsverschieben in seine Funktionsstellung verlagert wird.In order to maintain the stability of the angled leg of the extension arm, it is provided that the attachment tabs contain an open-edged and a closed recess, wherein the open-edged recess is formed as a slot and the closed recess contains a slot with an extension to the passage of one of the T-shaped webs , Notwithstanding this, it can be provided that at least one of the recesses is L-shaped and laterally open, so that the web can be inserted into the recess laterally on the leg and is displaced by its longitudinal displacement into its functional position.

Fig. 1 zeigt leicht schematisiert einen Flügel 1 eines Drehkipp-Fensters, der um eine untere horizontale und eine seitliche vertikale Achse schwenkbar ist. Dazu ist der Flügel 1 an seinem oberen horizontalen Flügelschenkel mit dem Blendrahmen 2 über eine Ausstellvorrichtung 3 verbunden. Die Ausstellvorrichtung 3 ist mit einem Ausstellarm 4 versehen, der einenends an dem horizontalen Flügelschenkel schwenk- und verschiebbar gelagert ist und anderenends einem Schwenklager 5 zugeordnet ist. Fig. 1 shows slightly schematically a wing 1 of a tilt-and-turn window, which is pivotable about a lower horizontal and a lateral vertical axis. For this purpose, the wing 1 is connected at its upper horizontal wing leg with the frame 2 via a display device 3. The opening device 3 is provided with a stay arm 4, which is pivotally and slidably mounted at one end to the horizontal wing leg and the other end is associated with a pivot bearing 5.

Das Schwenklager 5 besteht aus einem am Blendrahmen 2 zu befestigenden Lagerbock 6 und einem Flügelteil 7, das mit dem Lagerbock 6 mittels eines eine Hülse 8 des Flügelteils 7 durchsetzenden Gelenkbolzens 9 schwenkbar verbunden ist, wie ein Vergleich mit der Fig. 2 zeigt. Wie auch in Verbindung mit der Fig. 3 ersichtlich, schließt sich an die Hülse 8 ein abgewinkelter Bandlappen 10 an, dessen Befestigungslappen 11 zur Kopplung mit einem abgewinkelten Schenkel 12 des Ausstellarms 4 dient.The pivot bearing 5 consists of a frame 2 to be fixed to the bearing block 6 and a wing part 7, which is pivotally connected to the bearing block 6 by means of a sleeve 8 of the wing part 7 passing through hinge pin 9, as a comparison with the Fig. 2 shows. As synonymous in connection with the Fig. 3 can be seen, adjoins the sleeve 8 an angled hinge tabs 10, the fastening tabs 11 is used for coupling with an angled leg 12 of the stay 4.

Es kann aber abweichend von der Darstellung nach Fig. 2 und 3 auch vorgesehen werden, dass anstelle der einteiligen Ausgestaltung des Ausstellarms 4 ein Winkelstück vorgesehen wird, welches mit einem Schenkels an dem Ausstellarm 4 angeschlossen ist und mit dem anderen Schenkel den Schenkel 12 bildet.However, it may differ from the illustration FIGS. 2 and 3 also be provided that instead of the one-piece design of the extension arm 4, an elbow is provided, which is connected with a leg on the stay 4 and forms the leg 12 with the other leg.

In den Fig. 3 und 4 ist die Verbindung des Schenkels 12 des Ausstellarms 4 und des Befestigungslappens 11 erkennbar. Der Befestigungslappen 11 ist auf seiner dem Schenkel 12 zugeordneten Fläche mit einen im wesentlichen T-förmigen Steg 13 versehen.In the Fig. 3 and 4 is the connection of the leg 12 of the stay 4 and the mounting tab 11 recognizable. The mounting tabs 11 is provided on its the leg 12 associated surface with a substantially T-shaped ridge 13.

Ausweislich der Fign. 3 bis 6 bildet der Steg 13 zwei Formschlusselemente (Stege 13.1 und 13.2), indem der Steg 13 quer zu seiner Symmetrieachse unterbrochen wird. Der Steg 13.1 bzw. 13.2 durchgreift in seiner dargestellten Funktionsstellung (Fig. 3) den Schenkel 12 des Ausstellarms 4 in Öffnungen oder Ausnehmungen 14, 15, die in der Fig. 6 erkennbar sind. Die Ausnehmung 14 ist dabei als randoffener Schlitz ausgebildet, während die Ausnehmung 15 als geschlossene Ausnehmung einen Schlitz 16 mit einer Erweiterung 17 zum Durchtritt eines der T-förmigen Stege 13.1 bzw. 13.2 enthält. Der verbreiterte Kopf des Stegs 13 (bzw. der Stege 13.1 und 13.2 hintergreift dabei die Längsränder der Ausnehmungen 14, 15 im Bereich der engeren Abschnitte.Evidently the FIGS. 3 to 6 the web 13 forms two form-locking elements (webs 13.1 and 13.2) by the web 13 is interrupted transversely to its axis of symmetry. The web 13.1 or 13.2 passes through in its illustrated functional position ( Fig. 3 ) the leg 12 of the stay 4 in openings or recesses 14, 15, in the Fig. 6 are recognizable. The recess 14 is designed as an open-edged slot, while the recess 15 as a closed recess a slot 16 with an extension 17 for the passage of one of the T-shaped webs 13.1 and 13.2 contains. The widened head of the web 13 (or the webs 13.1 and 13.2 engages behind the longitudinal edges of the recesses 14, 15 in the region of the narrower sections.

Abweichend davon kann nämlich vorgesehen sein, dass zumindest die Ausnehmung 15 eine L-förmige Kontur erhält, bei der ein Schenkel an einer Längskante des Schenkels 12 mündet. Dadurch kann der Steg 13.1 oder 13.2 mit seinem Fuß in die Ausnehmung seitlich am Schenkel eingeführt werden und durch längsverschieben in seine Funktionsstellung verlagert werden. Diese Ausgestaltung mindert durch die randoffene Ausnehmung jedoch die Stabilität des abgewinkelten Schenkels.By way of derogation, provision may be made for at least the recess 15 to have an L-shaped contour in which a leg opens on a longitudinal edge of the leg 12. As a result, the web can be inserted 13.1 or 13.2 with his foot in the recess laterally on the leg and be displaced by longitudinal displacement in its functional position. However, this embodiment reduces the stability of the angled leg due to the open-edged recess.

Die Befestigung des Flügelteils 7 an dem Schenkel 12 erfolgt in an sich bekannter Weise dadurch, dass einer der Stege -z.B. Steg 13.1 in die Erweiterung 17 der Ausnehmung 15 eingeführt wird, die dazu maßlich an den verbreiterten Kopf des Stegs 13 angepasst ist. Der zwischen den Ausnehmungen 14, 15 liegende Abschnitt 18 des Schenkels 12 liegt dazu zwischen den Stegen 13.1 und 13.2, die hier eine Unterbrechung 19 aufweisen. Durch ein Längsverschieben wird der Steg 13.1 nun in den schmalen und auf den Fuß des Steges 13 abgestimmten Schlitz 16 und der Steg 13.2 in den Schlitz 14 verschoben. Dadurch ist der Bandlappen 11 und der Schenkel 12 in Richtung 21 und entgegengesetzt dazu aneinander festgelegt.The attachment of the wing portion 7 to the leg 12 is carried out in a conventional manner in that one of the webs -zB web 13.1 is inserted into the extension 17 of the recess 15 which is dimensionally adapted to the widened head of the web 13. The lying between the recesses 14, 15 section 18 of the leg 12 is located between the webs 13.1 and 13.2, which have an interruption 19 here. By longitudinal displacement of the web 13.1 is now in the narrow and tuned to the foot of the web 13 slot 16 and the web 13.2 moved into the slot 14. As a result, the hinge flap 11 and the leg 12 in the direction 21 and opposite thereto is fixed to each other.

Durch die Unterbrechung 19 werden die Stege 13.1 und 13.2 aus dem Steg 13 gebildet, wie aus der Fig. 5 ersichtlich. Wie hier auch erkennbar ist vorgesehen, dass der Steg 13 mittels einer Bohrung 20 durchbrochen wird. Dadurch wird in einem Arbeitsgang eine hinreichend große Unterbrechung 19 des Steges 13 auf einfache Weise bewirkt, die darüber hinaus auch sehr einfach und maßhaltig ausgeführt werden kann. In Verbindung mit der Fig. 4 wird deutlich, dass die Bohrung 20 als flache zylindrische Ausnehmung an dem Befestigungslappen 11 ausgeführt ist. Dies vermeidet eine Schwächung des Befestigungslappens 11 und die Bohrung 20 kann als flache Sacklochbohrung beispielsweise mittels eines Schaftfräsers hergestellt werden.By the interruption 19, the webs 13.1 and 13.2 are formed from the web 13, as shown in Fig. 5 seen. As can also be seen here provided that the web 13 is broken by means of a bore 20. As a result, a sufficiently large interruption 19 of the web 13 is effected in a single operation in a simple manner, which can also be carried out very easily and dimensionally stable beyond. In conjunction with the Fig. 4 It is clear that the bore 20 is designed as a flat cylindrical recess on the fastening tabs 11. This avoids a weakening of the fastening tab 11 and the bore 20 can be produced as a flat blind hole, for example by means of an end mill.

Um ein Lösen der Verbindung von Befestigungslappen und Schenkel 12 zu verhindern ist vorgesehen, dass der Schenkel 12 mittels eines Sicherungselements 22 am Befestigungslappen 11 gehalten ist. Das Sicherungselement 22 besteht aus einer Blattfeder 23, die mittig zwischen den zwei als Formschlusselementen wirksamen Stegen 13.1 und 13.2 im Bereich der Unterbrechung 19 bzw. der Bohrung 20 liegt.In order to prevent loosening of the connection of fastening tabs and legs 12, it is provided that the leg 12 is held on the fastening tabs 11 by means of a securing element 22. The securing element 22 consists of a leaf spring 23 which lies centrally between the two webs 13.1 and 13.2, which act as form-locking elements, in the region of the interruption 19 or the bore 20.

Von besonderem Vorteil ist dabei die Ausgestaltung nach Fig. 5, bei der die Blattfeder 23 abschnittsweise in der Bohrung 20 aufgenommen ist und zumindest bereichsweise einen annähernd kreisförmigen und an die Bohrung 20 angepassten Umfang 24 hat. Dadurch ist die Blattfeder 23 nämlich bereits zumindest in Längsrichtung des Steges 13 festgelegt und trägt nicht auf den Befestigungslappen 11 auf. Anderenfalls wäre es nämlich notwendig, zwischen dem Befestigungslappen 12 und dem Schenkel 11 einen entsprechenden Freiraum vorzusehen. So kann die zur Herstellung der Unterbrechung 19 verwendete Bohrung 20 gleichzeitig den zur Unterbringung der Blattfeder 23 notwendigen Raum schaffen. Die Bohrung 20 und der darauf abgestimmte Umfang 24 erlauben aber darüber hinaus auch eine gewisse Festlegung der Blattfeder 23 quer zu dem Steg 13 - in Richtung 25 (Fig. 5), da bedingt durch die Herstellung der Unterbrechung 19 die Kante 26 in dieser Richtung einen geringen Hinterschnitt bildet.Of particular advantage is the embodiment according to Fig. 5 , in which the leaf spring 23 is partially received in the bore 20 and at least partially has an approximately circular and the bore 20 adapted circumference 24. As a result, the leaf spring 23 is already fixed at least in the longitudinal direction of the web 13 and does not bear on the fastening tabs 11. Otherwise, it would be necessary to provide a corresponding free space between the fastening tabs 12 and the legs 11. Thus, the bore 20 used to make the interruption 19 can simultaneously provide the space necessary to accommodate the leaf spring 23. However, the bore 20 and the matching circumference 24 also allow a certain fixing of the leaf spring 23 transversely to the web 13 - in the direction 25 (FIG. Fig. 5 ), since due to the production of the interruption 19, the edge 26 forms a slight undercut in this direction.

Der Hinterschnitt durch die Kante 26 kann beispielsweise bei der Montage der Blattfeder 23 an dem Schwenklager 5 verwendet werden, um eine kurzzeitige Fixierung herbei zu führen. Vorteilhafter für eine Ausrichtung ist es jedoch, wenn die Blattfeder 23 einen abgewinkelten Steg 27 aufweist, der an dem seitlichen Rand 28 des Befestigungslappens 11 anliegt. Hierdurch erhält die Blattfeder 23 eine entgegen der Richtung 25 wirkende definierte Ausrichtung relativ zum Befestigungslappen 11 und wird gleichzeitig auch innerhalb der Bohrung 20 rechtwinklig zum Befestigungslappen 11 ausgerichtet.The undercut through the edge 26 can be used, for example, during assembly of the leaf spring 23 on the pivot bearing 5 to a short-term Fixation bring about. However, it is more advantageous for an alignment if the leaf spring 23 has an angled web 27, which rests against the lateral edge 28 of the fastening tab 11. As a result, the leaf spring 23 receives a counter to the direction 25 acting defined orientation relative to the mounting tabs 11 and is also aligned within the bore 20 at right angles to the mounting tabs 11.

Die Funktion der Blattfeder 23 ist leicht ersichtlich: Bei der Montage des Flügelteils 7 an dem Schenkel 12 wird der Abschnitt 18 innerhalb der Unterbrechung 19 bzw. der Bohrung 20 angeordnet, wie vorstehend bereits beschrieben. Der Abschnitt 18 wirkt dabei auf die Federzunge 29, die dadurch in Richtung 21 in die flache Bohrung 20 hinein verschwenkt wird. Beim anschließenden Verschieben des Flügelteils 7 wird der Abschnitt 18 relativ zum Flügelteil 7 so weit verlagert, dass dieser zwischen dem Rand 30 der Federzunge 29 und dem Steg 13.1 bzw. 13.2 liegt. Springt die Federzunge 29 nun zurück, so liegt sie zwischen der Federzunge 29 und dem Steg 13.1 bzw. 13.2, so dass ein Zurückschieben nur unter gleichzeitiger Verformung der Blattfeder 23 möglich ist.The function of the leaf spring 23 is readily apparent: When mounting the wing portion 7 on the leg 12, the portion 18 is disposed within the interruption 19 and the bore 20, as already described above. The section 18 acts on the spring tongue 29, which is thereby pivoted in the direction 21 in the flat bore 20 into it. During the subsequent displacement of the wing part 7, the portion 18 is displaced so far relative to the wing part 7 that it lies between the edge 30 of the spring tongue 29 and the web 13.1 or 13.2. If the spring tongue 29 now springs back, it lies between the spring tongue 29 and the web 13.1 or 13.2, so that a pushing back is only possible with simultaneous deformation of the leaf spring 23.

Es ist leicht ersichtlich, dass dazu der lichte Abstand der Federzunge 29 und des Steges 13.1 oder 13.2 etwas größer bemessen sein muss als die Länge (entlang der Mittelachse 32) des Anschnitts 18. Es ist aus der Fig. 4 und auch der Fig. 7 erkennbar, dass die Federzunge 29 so gebogen ist, dass sie in den Bereich des Schenkels 12 vorragt.It is readily apparent that for this purpose the clear distance of the spring tongue 29 and the web 13.1 or 13.2 must be sized slightly larger than the length (along the central axis 32) of the gate 18. It is from the Fig. 4 and also the Fig. 7 recognizable that the spring tongue 29 is bent so that it projects into the region of the leg 12.

Zur unverlierbaren Befestigung der Blattfeder. Hierzu ist vorgesehen, dass der Befestigungslappen 11 einen parallel zur Schwenklagerachse, also der Hülse 8, verlaufenden Absatz 33 aufweist, an dem die Blattfeder 23 zumindest bereichsweise anliegt. Dies kann beispielsweise mittels eines Flügels 34 (Fig. 5) erfolgen, der seitlich neben dem in die Bohrung 20 eingreifenden kreisbogenförmigen Abschnitt liegt. Der Flügel 34 endet an einer zur Schwenklagerachse parallelverlaufenden Kante, welche nahe dem Absatz 33 zu liegen kommt. Der Absatz 33 kann abschnittsweise z.B. mittels eines Formstempels verformt werden, so dass der verformte Materialabschnitt 35 - wie in Fig 7 angedeutet - die Blattfeder 23 teilweise überlappt.For captive attachment of the leaf spring. For this purpose, it is provided that the fastening tabs 11 has a parallel to the pivot bearing axis, so the sleeve 8, extending shoulder 33, on which the leaf spring 23 abuts at least partially. This can be done, for example, by means of a wing 34 (FIG. Fig. 5 ), which lies laterally next to the circular arc-shaped section engaging in the bore 20. The wing 34 ends at an edge parallel to the pivot bearing axis edge, which comes to rest near the shoulder 33. The shoulder 33 can be partially deformed, for example, by means of a forming punch, so that the deformed material portion 35 - as in Fig. 7 indicated - the leaf spring 23 partially overlapped.

Für diese Ausgestaltung ist es zweckmäßig, dass der Absatz 33 deutlich neben dem verbreiterten Kopf des Stegs 13 liegt, damit der Absatz 33 mit dem Formstempel leicht erreichbar ist.For this embodiment, it is expedient that the shoulder 33 is clearly adjacent to the widened head of the web 13 so that the shoulder 33 is easily accessible with the forming punch.

Durch die beschriebene Ausgestaltung ist eine Herstellung des Flügelteils 7 aus einem gezogenen Profil leicht möglich, da zur Herstellung der Funktion ausschließlich eine Nachbearbeitung notwendig ist.By the described embodiment, a production of the wing part 7 from a drawn profile is easily possible, since only a reworking is necessary for the production of the function.
