Description

Die Erfindung betrifft ein Lager für einen gegen einen Rahmen schwenkbaren Flügel eines Fensters mit einem rahmenseitigen Lagerbock und mit einem flügelseitigen, gegenüber dem rahmenseitigen Lagerbock verdrehbaren Beschlagteil und mit einem in einer Drehachse der Beschlagteile liegenden Lagerbolzen, wobei der rahmenseitige Lagerbock aus einer Grundplatte und mindestens einem Lagerauge zur Aufnahme des Lagerbolzens besteht, wobei das Lagerauge durch Umformung einer einstückig an der Grundplatte angeordneten Lasche gebildet ist und das Lagerauge ein an der Grundplatte festes erstes Ende sowie ein zweites Ende aufweist und das Lagerauge zur sicheren Halterung des Lagerbolzens eine Rasthülse umschließt, wobei das zweite Ende des Lagerauges formschlüssig mit der Grundplatte verbunden ist und einen Fortsatz aufweist, der in eine zur Längsseite des Lagerbocks offene Ausnehmung der Grundplatte eingreift.The invention relates to a bearing for a sash of a window pivotable against a frame with a frame-side bearing block and with a sash-side fitting part rotatable with respect to the frame-side bearing block and with a bearing pin lying in an axis of rotation of the fitting parts, the frame-side bearing block comprising a base plate and at least one There is a bearing eye for receiving the bearing bolt, the bearing eye being formed by deformation of a bracket arranged in one piece on the base plate and the bearing eye having a first end fixed to the base plate and a second end and the bearing eye enclosing a locking sleeve for securely holding the bearing bolt, the The second end of the bearing eye is positively connected to the base plate and has an extension which engages in a recess of the base plate that is open to the longitudinal side of the bearing block.

Aus der DE 195 28 656 C1 ist ein Drehlagerbock aus einem Blechstück bekannt, bei dem freie Enden der Lappen formschlüssig in Ausnehmungen der Grundplatte eingreifen. Durch diese Anordnung ist ein weiteres verkleben oder verschweißen der Enden der Lappen mit der Grundplatte erforderlich.From the DE 195 28 656 C1 a rotary bearing block made from a piece of sheet metal is known in which the free ends of the tabs engage positively in recesses in the base plate. This arrangement means that the ends of the tabs must be further glued or welded to the base plate.

Aus der DE 093 08 669 U1 sind zapfenartige Verankerungselemente an einer Grundplatte eines Beschlagteils für die Verankerung eines Beschlagteils in einem Rahmen eines Fensters oder einer Tür bekannt.From the DE 093 08 669 U1 pin-like anchoring elements on a base plate of a fitting part for anchoring a fitting part in a frame of a window or door are known.

Die US 2009 307 871 A1 offenbart eine einstückige Lagerhülse, bestehend aus von einem Grundträger abstehenden Lappen, deren freie Enden zweier Lappen gegeneinander stehen und formschlüssig gekoppelt sind, wobei eine Kopplungsausnehmung eines Lappens stufig ausgebildet ist und der entgegenstehende Lappen ein korrespondierendes Formschlusselement aufweist. Diese auf der dem Grundträger abgewandten Seite der Lagerhülse angeordnete Formschlussverbindung kann hohe Zugkräfte von der einen zur anderen Lasche übertragen, jedoch ist die Stabilität bei Kräften senkrecht zu den Laschen, welche bei geöffnetem Flügel auftreten, nicht besonders hoch.The US 2009 307 871 A1 discloses a one-piece bearing sleeve consisting of tabs protruding from a base support, the free ends of two tabs of which stand against one another and are positively coupled, a coupling recess of one tab being stepped and the opposing tab having a corresponding form-locking element. This form-fit connection, which is arranged on the side of the bearing sleeve facing away from the base support, can transfer high tensile forces from one tab to the other, but the stability is not particularly high with forces perpendicular to the tabs, which occur when the sash is open.

Ein ähnliches Lager ist bereits aus der DE 1 972 819 U bekannt. Hierbei ist das Lager komplett aus einem Blechstück geformt und weist eine durchgängige Rolle zum Umschluss des Lagerbolzens auf. Kennzeichnend für die beschriebene Erfindung ist, dass die Form der Rolle während der Montage des Fensters angepasst und somit auf die Gegebenheiten angepasst werden kann. Hierzu kann die Krümmung der Rolle mithilfe eines entsprechenden Werkzeugs eingestellt werden. Nachteilig an dieser Erfindung ist jedoch, dass die Rolle nicht an der Grundplatte selbst fixiert wird, sondern im Rahmen der Montage lediglich durch eine elastische Hülse verschlossen wird, was zu Einbußen in der Stabilität des Lagers führt.A similar camp is already out of the DE 1 972 819 U known. Here, the bearing is completely formed from a piece of sheet metal and has a continuous roller to enclose the bearing pin. A characteristic of the invention described is that the shape of the Role adjusted during the installation of the window and thus adapted to the circumstances. For this purpose, the curvature of the roller can be adjusted using an appropriate tool. The disadvantage of this invention, however, is that the roller is not fixed to the base plate itself, but is merely closed by an elastic sleeve during assembly, which leads to a loss in the stability of the bearing.

Heutzutage übliche Zinkdruckgusslager, oder zumindest Zinkdruckguss-Stahlverbund-Lager, welche eine geschlossene Lagerung für den Lagerbolzen bieten und eine einstückige Ausbildung des Lagers zulassen, können aufgrund des verwendeten Materials ebenfalls eine geringere Stabilität aufweisen.Zinc die-cast bearings that are common nowadays, or at least zinc die-cast steel composite bearings, which offer a closed bearing for the bearing pin and allow the bearing to be formed in one piece, can also have a lower stability due to the material used.

Der Erfindung liegt das Problem zugrunde ein Lager der eingangs erwähnten Art so weiterzubilden, dass es eine hohe Stabilität und Betätigungssicherheit aufweist.The invention is based on the problem of developing a bearing of the type mentioned at the beginning in such a way that it has a high level of stability and operational reliability.

Das Problem wird erfindungsgemäß dadurch gelöst, dass die Ausnehmung stufig ausgebildet ist, mit einem erweiterten Aufnahmebereich in Richtung der dem Rahmen zugewandten Unterseite der Grundplatte und dass der Fortsatz an seinem freien Ende einen verbreiterten Kopf aufweist, welcher in den erweiterten Aufnahmebereich der Ausnehmung der Grundplatte angeordnet werden kann und die Grundplatte somit hintergreift.The problem is solved according to the invention in that the recess is designed in steps, with an expanded receiving area in the direction of the underside of the base plate facing the frame and that the extension has a widened head at its free end, which is arranged in the expanded receiving area of the recess of the base plate can be and thus engages behind the base plate.

Durch diese Gestaltung weist das Lager, welches den Lagerbolzen aufnimmt und somit das Flügelgewicht am Rahmen hält, eine erhöhte Stabilität gegenüber einseitig offenen Lagern auf. Die Stabilität gegenüber herkömmlichen Zinkdruckgusslagern kann durch Verwendung von beispielsweise Stahlblech zur Umformung erhöht werden. Das Lager ist üblicherweise als Drehlager ausgeführt und kann nahe der oberen Ecke, nahe der unteren Ecke oder dazwischen entlang der Drehachse eines zumindest drehbaren Flügels eines Fensters oder einer Tür angeordnet sein. Die Aufnahme des Fortsatzes wird optimiert, wenn die Ausnehmung stufig ausgebildet ist, mit einem erweiterten Aufnahmebereich in Richtung der dem Rahmen zugewandten Unterseite der Grundplatte. Dadurch wird Raum geschaffen für Materialüberstände und als Toleranzausgleich. Da der Fortsatz an seinem freien Ende einen verbreiterten Kopf aufweist, welcher in den erweiterten Aufnahmebereich der Ausnehmung der Grundplatte angeordnet werden kann und die Grundplatte somit hintergreift, wird auf einfache Art ein Formschluss zwischen dem zweiten Ende des Lagerauges und der Grundplatte erzeugt. Somit wird das zweite Ende an der Grundplatte fixiert und kann nicht von der Grundplatte weg aus der Ausnehmung herausgezogen werden.As a result of this design, the bearing, which receives the bearing pin and thus holds the sash weight on the frame, has increased stability compared to bearings that are open on one side. The stability compared to conventional zinc die-cast bearings can be increased by using, for example, sheet steel for forming. The bearing is usually designed as a pivot bearing and can be arranged near the upper corner, near the lower corner or in between along the axis of rotation of an at least rotatable sash of a window or door. The reception of the extension is optimized if the recess is stepped with an enlarged reception area in the direction of the underside of the base plate facing the frame. This creates space for excess material and as tolerance compensation. Since the extension has a widened head at its free end, which can be arranged in the extended receiving area of the recess of the base plate and thus engages behind the base plate, a positive fit between the second end of the bearing eye and the base plate is produced in a simple manner. The second end is thus fixed to the base plate and cannot be pulled out of the recess away from the base plate.

Eine Verbindung kann gemäß einer vorteilhaften Weiterbildung der Erfindung auch dadurch erreicht werden, dass der Kopf in dem stufigen, erweiterten Aufnahmebereich der Ausnehmung der Grundplatte mittels Umformen gebildet wird. Durch diese Ausführung kann der Fortsatz zunächst sehr schmal ausgeführt werden, so dass er direkt in Richtung der Grundplatte in die Ausnehmung eingeführt werden kann und nicht von der Seite eingeschwenkt werden muss. Durch das anschließende Umformen, bevorzugt nach dem Einführen des Fortsatzes in die Ausnehmung, kann ein zur Ausnehmung spielfreier Kopf im erweiterten Aufnahmebereich der Ausnehmung erzeugt werden. Dies verbessert den spielfreien Formschluss und damit das Lagerspiel. Es ist bevorzugt maximal so viel umformbares Material vorhanden, wie in den erweiterten Aufnahmebereich der Ausnehmung aufgenommen werden kann, um eine weitgehend ebene Auflagefläche der Grundplatte beizubehalten.According to an advantageous development of the invention, a connection can also be achieved in that the head is formed in the stepped, expanded receiving area of the recess of the base plate by means of reshaping. As a result of this design, the extension can initially be made very narrow so that it can be inserted directly into the recess in the direction of the base plate and does not have to be pivoted in from the side. As a result of the subsequent reshaping, preferably after the extension has been introduced into the recess, a head free of play with respect to the recess can be produced in the enlarged receiving area of the recess. This improves the backlash-free form fit and thus the bearing play. There is preferably at most as much deformable material as can be received in the expanded receiving area of the recess in order to maintain a largely flat support surface of the base plate.

Eine vollständig formschlüssige Verbindung ist gemäß einer vorteilhaften Weiterbildung der Erfindung dann besonders sicher gestaltet, wenn der erweiterte Aufnahmebereich als Kreis ausgebildet ist, wobei die Mitte des erweiterten Aufnahmebereichs einen Abstand kleiner ihrem Radius zur Längskante der Grundplatte aufweist, so dass eine Kreisöffnung an der Längsseite ausgebildet ist. Hierdurch wird eine stabilere Verbindung des zweiten Endes des Lagerauges mit der Grundplatte und somit ein erhöhter Widerstand gegen eine ungewollte Verformung des Lagerauges gewährleistet. Des Weiteren gestaltet sich das Einschwenken des Fortsatzes einfacher und ein formschlüssiger Halt gegen sein Zurückschwenken wird gewährleistet, da der Kreisdurchmesser größer ist als die Kreisöffnung an der Längskante der Grundplatte. Es wird hierbei idealerweise ein runder Fortsatz verwendet, der einen Durchmesser kleiner der Breite der an der Längsseite des Lagerbocks offene Ausnehmung der Grundplatte aufweist und so lang ist, dass nach einem Umformvorgang des Fortsatzes der erweiterte Aufnahmebereich zumindest teilweise ausgefüllt ist.According to an advantageous development of the invention, a completely form-fitting connection is designed to be particularly secure if the expanded receiving area is designed as a circle, the center of the expanded receiving area being at a distance smaller than its radius from the longitudinal edge of the base plate, so that a circular opening is formed on the longitudinal side is. This ensures a more stable connection of the second end of the bearing eye with the base plate and thus increased resistance to undesired deformation of the bearing eye. Furthermore, the pivoting in of the extension is made easier and a form-fitting hold against pivoting it back is ensured, since the circular diameter is larger than the circular opening on the longitudinal edge of the base plate. A round extension is ideally used here, which has a diameter smaller than the width of the opening in the base plate on the longitudinal side of the bearing block and is so long that the extended receiving area is at least partially filled after a deformation process of the extension.

Die Rasthülsen werden nach einer anderen vorteilhaften Weiterbildung der Erfindung gegen ungewolltes Verdrehen gesichert, wenn der Querschnitt des Lagerauges auf der Innenseite zumindest eine Gerade und einen Radius aufweist und die Außenkontur der Rasthülse an die Form des Lagerauges angepasst ist.According to another advantageous development of the invention, the locking sleeves are secured against unwanted rotation when the cross section of the bearing eye has at least one straight line and a radius on the inside and the outer contour of the locking sleeve is adapted to the shape of the bearing eye.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist das Lager so ausgeführt, dass das Lagerauge die Rasthülse größtenteils umschließt und die Rasthülse das Lagerauge zumindest von einer Seite hintergreift. Hierdurch kann die Rasthülse gegen ein Verschieben in Richtung der Drehachse des Lagerbolzens gesichert werden.According to an advantageous development of the invention, the bearing is designed in such a way that the bearing eye largely surrounds the locking sleeve and the locking sleeve engages behind the bearing eye from at least one side. In this way, the locking sleeve can be secured against displacement in the direction of the axis of rotation of the bearing pin.

Das Lager ist nach einer vorteilhaften Weiterbildung verschleißarm, wenn bei einer Ausführung mit mindestens zwei Lageraugen die Grundplatte auf einer Längsseite eine längs verlaufende Schrägkante aufweist, die zwischen den Lageraugen verläuft und auf der Seite der formschlüssigen Verbindung angeordnet ist. Das Lager wird vorzugsweise mit der Schrägkante in Richtung Flügel angeordnet und somit sichert diese ein reibungsloses Drehen des Flügels in die Geschlossenstellung und schafft Raum für die stabile Ausgestaltung des flügelseitigen Beschlagteils, was auf Dauer für weniger Verschleiß und eine leichtere Bedienung sorgt.According to an advantageous further development, the bearing is wear-resistant if, in an embodiment with at least two bearing eyes, the base plate has a longitudinally extending sloping edge on one longitudinal side, which runs between the bearing eyes and is arranged on the side of the positive connection. The bearing is preferably arranged with the sloping edge in the direction of the sash and thus ensures smooth turning of the sash into the closed position and creates space for the stable design of the sash-side fitting part, which in the long term ensures less wear and tear and easier operation.

Das Lager lässt sich gemäß einer weiteren vorteilhaften Weiterbildung der Erfindung noch stabiler ausführen, wenn auf der der Schrägkante gegenüberliegenden Längsseite des Lagers ein Steg angeordnet ist, der zwischen den Lageraugen verläuft und während der Umformung der Lageraugen einstückig mit geformt wird.According to a further advantageous development of the invention, the bearing can be made even more stable if a web is arranged on the longitudinal side of the bearing opposite the sloping edge, which runs between the bearing eyes and is formed in one piece during the deformation of the bearing eyes.

Die Montage des Lagers lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung verbessern, wenn die Grundplatte an ihrer dem Rahmen zugewandten Unterseite mindestens einen Zapfen ausweist. Hierdurch lässt sich die Grundplatte in einer im Rahmen eingebrachten Ausnehmung, welche die Kontur des Zapfens aufweist, fixieren. Dadurch bietet der Zapfen einen verlässlichen Schutz gegen ungewolltes Verdrehen oder Verschieben des Lagers während der Montage und im montierten Zustand.According to another advantageous development of the invention, the mounting of the bearing can be improved if the base plate is on its underside facing the frame identifies at least one pin. As a result, the base plate can be fixed in a recess made in the frame, which has the contour of the pin. As a result, the pin offers reliable protection against unintentional twisting or displacement of the bearing during assembly and in the assembled state.

Das Lager ist gemäß einer anderen vorteilhaften Weiterbildung so gestaltet, dass die Grundplatte Verlängerungen aufweist, die über die Außenseiten der Lageraugen hinausgehen. Somit sind mehr Möglichkeiten zur Befestigung und zur Handhabe des Lagers gegeben.According to another advantageous development, the bearing is designed in such a way that the base plate has extensions that extend beyond the outer sides of the bearing eyes. This means that there are more options for fastening and handling the bearing.

Figur 1 zeigt ein Fenster mit einem Rahmen 1, einem Flügel 2 und einem erfindungsgemäßen Lager 3. Das Fenster kann mittels einer Handhabe beispielsweise in gewohnter Dreh- oder Dreh-Kipp-Bewegung verlagert werden. Das Lager kann auch für andere Bauteile, wie Fenstertüren oder Türen, verwendet werden und ist überall entlang der Drehachse des Flügels einsetzbar. Bei Dreh-Kipp-Fenstern ist das beschriebene Lager als oberes Flügellager einsetzbar, wobei die Kippbewegung durch eine obere Öffnungsschere und zumindest ein unteres Kipplager ermöglicht wird. Figure 1 shows a window with a frame 1, a sash 2 and a bearing 3 according to the invention. The window can be displaced by means of a handle, for example in the usual turn or turn-tilt movement. The bearing can also be used for other components, such as French doors or doors, and can be used anywhere along the axis of rotation of the sash. In the case of turn-tilt windows, the bearing described can be used as an upper sash bearing, the tilting movement being made possible by an upper opening scissor and at least one lower tilting bearing.

Figur 2 zeigt ein erfindungsgemäßes Lager 3. Es besteht aus einem flügelseitigen Beschlagteil 4 und einem rahmenseitigen Lagerbock 6. Beide Teile sind über einen Lagerbolzen 5 miteinander drehgelagert Verbunden. Figure 2 shows a bearing 3 according to the invention. It consists of a sash-side fitting part 4 and a frame-side bearing block 6. Both parts are connected to one another by means of a bearing pin 5 in a rotationally mounted manner.

Figur 3 zeigt einen Lagerbock 6. Er besteht aus einer Grundplatte 7 und zwei Lageraugen 8, wobei die Abwicklung des Vormaterials aus der Grundplatte 7 mit zwei abstehenden Laschen besteht, wobei die Lageraugen 8 aus den von der Grundplatte 7 abstehenden Laschen durch Umformung, wie beispielsweise Walzen oder Biegen, hergestellt wurden. Die Lageraugen 8 weisen dabei ein einstückig mit der Grundplatte 7 verbundenes erstes Ende 23 sowie ein zweites Ende 24 auf, welches zur Fixierung der Lageraugenform nach der Herstellung dieser dient. Die Lageraugen 8 umfassen jeweils eine Rasthülse 9, in welchen der später einführbare Lagerbolzen 5 fixiert werden kann. Weiterhin weist die Grundplatte 7 eine Schrägkante 10, die im montierten Zustand dem Flügel 2 zugewandt ist, und einen Steg 11 auf der gegenüberliegenden Längsseite auf. Beide verlaufen zwischen den Lageraugen 8. Der Steg 11 wird ebenfalls während der Blechumformung aus dem einstückigen Blech gebildet und erhöht die Stabilität des Lagerbocks 6. Des Weiteren bildet er einen seitlichen Abschluss der Lagerbolzenaufnahme. Figure 3 shows a bearing block 6. It consists of a base plate 7 and two bearing eyes 8, whereby the development of the raw material consists of the base plate 7 with two protruding tabs, the bearing eyes 8 from the tabs protruding from the base plate 7 by forming, such as rolling or Bending. The bearing eyes 8 have a first end 23, which is integrally connected to the base plate 7, and a second end 24 which is used to fix the bearing eye shape after it has been manufactured. The bearing eyes 8 each comprise a locking sleeve 9 in which the bearing pin 5, which can be inserted later, can be fixed. Furthermore, the base plate 7 has an inclined edge 10, which faces the wing 2 in the assembled state, and a web 11 on the opposite longitudinal side. Both run between the bearing eyes 8. The web 11 is also formed from the one-piece sheet metal during the sheet metal forming and increases the stability of the bearing block 6. Furthermore, it forms a lateral closure of the bearing pin receptacle.

Figur 4 zeigt den erfindungsgemäßen Lagerbock 6 aus Figur 3 in der Seitenansicht. Neben den bereits genannten technischen Merkmalen sind in dieser Ansicht zwei Zapfen 13 zu erkennen, welche an der Unterseite der Grundplatte 7 in Richtung des Rahmens 1 hervorstehen. Diese können zur vorläufigen Ausrichtung und Fixierung des Lagerbocks 6 am Rahmen 1 verwendet werden und gestatten somit eine einfache Montierung des Lagers 3 sowie eine höhere Lagestabilität des Lagerbocks 6 nach der Montage. Zudem ist diese Ansicht auf die formschlüssige Verbindung ausgerichtet, sodass erkennbar ist, dass an den zweiten Enden 24 der Lageraugen 8 ein Fortsatz 14 angebracht ist, welcher in eine Ausnehmung 15 der Grundplatte 7 greift. Die Ausnehmung 15 ist stufig ausgebildet, sodass es einen erweiterten Aufnahmebereich 16 für einen abschließenden pilzkopfartigen Materialfortsatz, wie beispielsweise einen vorgeformten oder einen durch nachträgliches Umformen hergestellten Kopf 20 oder eine Stauchung, und einen definierten Aufnahmebereich für den Fortsatz 14 selbst gibt. Des Weiteren ist zu erkennen, dass die Rasthülse 9 weitestgehend von dem Lagerauge 8 umschlossen wird und lediglich ein Kopfteil der Rasthülse 9 freiliegend bleibt. Figure 4 shows the bearing block 6 according to the invention Figure 3 in side view. In addition to the technical features already mentioned, two pins 13 can be seen in this view, which protrude on the underside of the base plate 7 in the direction of the frame 1. These can be used for the preliminary alignment and fixation of the bearing block 6 on the frame 1 and thus allow easy mounting of the bearing 3 and a higher positional stability of the bearing block 6 after assembly. In addition, this view is oriented towards the positive connection, so that it can be seen that an extension 14 is attached to the second ends 24 of the bearing eyes 8, which extension engages in a recess 15 in the base plate 7. The recess 15 is stepped, so that there is an expanded receiving area 16 for a final mushroom-shaped Material extension, such as a preformed head 20 or a head 20 produced by subsequent deformation, or a compression, and a defined receiving area for the extension 14 itself. It can also be seen that the locking sleeve 9 is largely enclosed by the bearing eye 8 and only a head part of the locking sleeve 9 remains exposed.

Figur 5 zeigt das erfindungsgemäße Lagerauge 8 in vergrößerter Darstellung entlang der Drehachse des Lagerbolzens 5. Auch hier ist wieder die als Zapfen 13 ausgeführte Erhebung an der Unterseite der Grundplatte 7 zu erkennen. Weiterhin ist erkennbar, dass das Lagerauge 8 an seiner Innenseite unter anderem aus einem geraden Abschnitt 18 und einem Radius 19 gebildet wird. Des Weiteren sind das erste Ende 23 und das zweite Ende 24 des Lagerauges 8 gezeigt, welche dieses mit der Grundplatte 7 verbinden. Die Außenkontur 22 der Rasthülse 9 ist an diese Form des Lagerauges 8 angepasst, sodass ein ungewolltes verdrehen der Rasthülse 9 ausgeschlossen ist. Weiterhin ist zu erkennen, dass der Kopf der Rasthülse 9 die Innenseite 17 des Lagerauges 8 überlappt und es somit hintergreift. Dies gewährleistet einen zusätzlichen Halt der Rasthülse 9
In Figur 6 ist ein Lagerauge 8 erfindungsgemäßer Ausführung in vergrößerter Seitenansicht zu sehen. Die Fixierung des zweiten Endes 24 des Lagerauges 8 wird in diesem Ausführungsbeispiel mittels eines rechteckigen Kopfes 20, welcher an dem Fortsatz 14 ausgebildet ist, umgesetzt. Dieser hintergreift nach der Umformung des Blechstücks in dem erweiterten Aufnahmebereich 16 der Ausnehmung 15 die Grundplatte 7 und sorgt so für den Verschluss des Lagerauges 8. Figure 5 shows the bearing eye 8 according to the invention in an enlarged representation along the axis of rotation of the bearing pin 5. Here, too, the elevation designed as a pin 13 on the underside of the base plate 7 can be seen again. It can also be seen that the bearing eye 8 is formed on its inside from a straight section 18 and a radius 19, among other things. Furthermore, the first end 23 and the second end 24 of the bearing eye 8 are shown, which connect it to the base plate 7. The outer contour 22 of the locking sleeve 9 is adapted to this shape of the bearing eye 8, so that unwanted rotation of the locking sleeve 9 is excluded. It can also be seen that the head of the locking sleeve 9 overlaps the inside 17 of the bearing eye 8 and thus engages behind it. This ensures an additional hold for the locking sleeve 9
In Figure 6 a bearing eye 8 according to the invention can be seen in an enlarged side view. The fixing of the second end 24 of the bearing eye 8 is implemented in this exemplary embodiment by means of a rectangular head 20 which is formed on the extension 14. After the deformation of the sheet metal piece, this engages behind the base plate 7 in the enlarged receiving area 16 of the recess 15 and thus ensures the closure of the bearing eye 8.

Eine zweite Ausführungsform der formschlüssigen Verbindung ist in Figur 7 gezeigt. Nachdem das Lagerauge 8 durch die erste Umformung gebogen ist, wird es mittels einer weiteren Umformung an der Grundplatte 7 fixiert. Somit wird ein kompletter Formschluss der Verbindung zwischen Grundplatte 7 und dem zweiten Ende 24 des Lagerauges 8 erreicht.A second embodiment of the positive connection is shown in FIG Figure 7 shown. After the bearing eye 8 has been bent by the first deformation, it is fixed on the base plate 7 by means of a further deformation. A complete form fit of the connection between the base plate 7 and the second end 24 of the bearing eye 8 is thus achieved.

Die Figur 8 und Figur 9 zeigen die Rückseiten der in Figur 6 und Figur 7 dargestellten erfindungsgemäßen Ausführungsformen des Lagerbocks 6. Es sind die formschlüssigen Verbindungen des zweiten Endes 24 des Lagerauges 8 mit der Grundplatte 7 mittels des Fortsatzes 14 gezeigt. In Figur 8 ist die Ausführung, welche die Verbindung mittels hintergreifen herstellt, gezeigt und der rechteckige Kopf 20 des Fortsatzes 14 ist zu erkennen. Dieser ist in den entsprechend geformten erweiterten Aufnahmebereich 16 der Grundplatte 7 eingeführt. Dies ist bei vorgeformtem rechteckigen Kopf 20 durch einschwenken von der Öffnung an der Längsseite der Grundplatte 7 möglich. In Figur 9 ist die Variante mittels Verformung gezeigt. Hierbei wurde ein Niet 21 in einem formangepassten erweiterten Aufnahmebereich 16 angeordnet und bildet nach dem Umformvorgang den dargestellten vollständigen Formschluss zur Verbindung des zweiten Endes 24 des Lagerauges 8 mit der Grundplatte 7. Der erweiterte Aufnahmebereich 16 ist in diesem Fall kreisförmig ausgebildet und so angeordnet, dass eine Kreisöffnung an der Längskante der Grundplatte vorhanden ist, welche bündig mit dem Niet 21 schließt. Die Kreisöffnung an der Längskante der Grundplatte 7 ist schmaler als der Durchmesser des kreisförmigen erweiterten Aufnahmebereichs 16.The Figure 8 and Figure 9 show the backs of the in Figure 6 and Figure 7 The illustrated embodiments of the bearing block 6 according to the invention. The form-fitting connections of the second end 24 of the bearing eye 8 with the base plate 7 by means of the extension 14 are shown. In Figure 8 the design that establishes the connection by reaching behind is shown and the rectangular head 20 of the extension 14 can be seen. This is inserted into the correspondingly shaped, expanded receiving area 16 of the base plate 7. In the case of a preformed rectangular head 20, this is possible by pivoting it in from the opening on the longitudinal side of the base plate 7. In Figure 9 the variant by means of deformation is shown. This was a rivet 21 in one shape-adapted extended receiving area 16 and after the forming process forms the complete form fit shown to connect the second end 24 of the bearing eye 8 to the base plate 7. The enlarged receiving area 16 is circular in this case and is arranged so that a circular opening on the longitudinal edge of the base plate is present, which closes flush with the rivet 21. The circular opening on the longitudinal edge of the base plate 7 is narrower than the diameter of the circular, expanded receiving area 16.
