Description

Die Erfindung betrifft einen Rollenbolzen nach dem Oberbegriff des Anspruchs 1 und 11.The invention relates to a roller bolt according to the preamble of claim 1 and 11.

Rollenbolzen der vorgenannten Art sind bereits bekannt. Aus der DE 29 03 837 C3 geht beispielsweise ein Rollenbolzen hervor, der eine auf einem Bundbolzen geführte Rolle aus Metall aufweist. Die Rolle ist innenseitig mit in Längsrichtung versetzt angeordneten Rillen oder Nuten versehen, die zum Eingriff eines Sicherungselementes in Form eines Spreizringes dienen. Dadurch lässt sich die Rolle relativ zu dem Bundbolzen in verschiedenen Lagen einstellen.Roller bolts of the aforementioned type are already known. From the DE 29 03 837 C3 For example, a roller bolt protrudes, which has a guided on a collar bolt roller made of metal. The roller is provided on the inside with offset longitudinally arranged grooves or grooves, which serve for engagement of a securing element in the form of a spreader ring. As a result, the role can be adjusted relative to the collar bolt in different positions.

Um beim Zusammenwirken der Rolle und dem Riegelsteg eine noch geringere Reibung zu erzielen, wird nach der DE 29 03 099 A1 vorgeschlagen, anstelle der Rolle aus Metall eine Rolle aus Kunststoff vorzusehen. Die elastischen Eigenschaften des Kunststoffes erlauben es, das Sicherungselement in die Rolle zu integrieren. An der Rolle ist dazu ein Hinterschnitt vorgesehen, der von einem Vorsprung des Bundbolzens hintergriffen wird. Um unterschiedliche Anwendungsbereiche hinsichtlich des Schließdrucks abdecken zu können ist vorgesehen, dass dem Bundbolzen Rollen mit verschiedenen Außendurchmesser zuordenbar sind, so dass diese ggf. austauschbar sind.In order to achieve an even lower friction during the interaction of the roller and the locking bar, according to the DE 29 03 099 A1 proposed to provide a plastic roller instead of the metal roller. The elastic properties of the plastic make it possible to integrate the securing element in the role. On the role of an undercut is provided, which is engaged behind by a projection of the collar bolt. In order to be able to cover different fields of application with regard to the closing pressure, provision is made for rollers with different outer diameters to be assigned to the collar bolt so that they may be exchangeable.

Es hat sich dabei gezeigt, dass die vergleichsweise dünne Rolle unter bestimmten Umständen beschädigt werden kann, insbesondere an den dünneren Längsenden. Dies ist insbesondere der Fall bei längsverschiebbaren Riegelzapfen, die ortsfeste Riegelstege hintergreifen und dabei nicht entlang ihrer gesamten Höhe an diesen anliegen. Die Rolle gelangt dann nur mit dem in Richtung des freien Endes gelegenen Endabschnitts in Anlage an den Riegelsteg, so dass vergleichsweise hohe Kräfte auf eine nur geringe Fläche wirken.It has been shown that the comparatively thin roll can be damaged in certain circumstances, especially at the thinner longitudinal ends. This is the case in particular with longitudinally displaceable locking pins, which engage behind fixed bolt webs and do not rest against them along their entire height. The roller then comes into contact with the locking bar only with the end section located in the direction of the free end, so that comparatively high forces act on only a small area.

Daher ist bereits in der DE 27 51 813 C2 vorgeschlagen worden, das freie Ende der Hülse mit einer Verdickung auszuführen, so dass die Hülse eine pilzkopfartige Form erhält.Therefore already in the DE 27 51 813 C2 has been proposed to perform the free end of the sleeve with a thickening, so that the sleeve receives a mushroom-like shape.

Durch die DE 6937034 U1 ist zwar bereits der Vorschlag gemacht worden, Riegelglieder von Flügelverschlüssen mit reibungsarmem Material, beispielsweise Polytetraflouräthylen, zu armieren bzw. zu beschichten, jedoch ist nicht vorgesehen, diese Beschichtung gleichzeitig auch als Führungselement für ein Verstellmittel zu benutzen.By the DE 6937034 U1 Although the proposal has already been made to reinforce latch members of wing locks with low-friction material, such as Polytetraflouräthylen, or to coat, but it is not intended to use this coating at the same time as a guide element for an adjustment.

Auch durch die DE-OS 27 51 813 ist ein Flügelverschluss für Fenster oder Türen bekannt geworden, dessen Riegelzapfen an seiner Umfangsfläche mit einer Ummantelung aus verschleißfestem Werkstoff versehen ist, die entweder aus einem drehfest aufgepressten Ring oder einer Hülse oder aber aus einer Umfangsbeschichtung aus Kunststoff, z. B. Polyamid oder Polycarbonat, besteht und eine Verbesserung der Gleiteigenschaften für die Riegelzapfen beim Zusammenwirken mit den rahmenseitigen Riegelstegen erreicht. Eine ähnliche Lösung findet sich auch in der DE 32 03 421 A1 .Also by the DE-OS 27 51 813 is known a wing closure for windows or doors, the locking pin is provided on its peripheral surface with a sheath made of wear-resistant material, either from a rotatably pressed ring or a sleeve or from a peripheral coating made of plastic, z. For example, polyamide or polycarbonate, and an improvement in the sliding properties of the locking pins when interacting with the frame-side locking bars achieved. A similar solution can be found in the DE 32 03 421 A1 ,

Der Erfindung liegt daher die Aufgabe zugrunde, einen Rollenbolzen dahingehend weiterzuentwickeln, dass er einerseits kostengünstig herstellbar und montierbar ist, andererseits aber die Reibung an dem Riegelsteg reduziert und gegen Beschädigungen resistenter ist.The invention is therefore based on the object to develop a roller bolt to the effect that on the one hand it is inexpensive to produce and assemble, but on the other hand reduces the friction on the bolt web and is more resistant to damage.

In den kennzeichnenden Teilen der Ansprüche 1 und 11 sind entsprechende Lösungen angegeben.In the characterizing parts of claims 1 and 11 corresponding solutions are given.

Die Ausgestaltung der Rolle als Metallhülse, die von einem Kunststoff überzogen ist, bietet die Vorteile der stabilen Ausgestaltung und vermeidet das unmittelbare Zusammenwirken des Metalls der Rolle und des Riegelstegs. Andererseits wird der Rolle eine ausreichende Stabilität gegeben, so dass diese auch unter extremen Bedingungen beschädigungsfrei bleibt. Durch die im Anspruch 11 angegebene Lösung wird eine reibungsgeminderte Lösung geschaffen, welche eine Beschädigung der Rolle im Bereich des höherbelasteten Abschnitts des freien Endes des Rollenbolzens vermeidet.The design of the roller as a metal sleeve, which is covered by a plastic, offers the advantages of stable design and avoids the direct interaction of the metal of the roller and the locking bar. On the other hand, the roll is given sufficient stability so that it remains free of damage even under extreme conditions. The solution specified in claim 11 becomes a friction-reduced solution created which avoids damage to the roller in the region of the higher loaded portion of the free end of the roller bolt.

Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Ansprüchen 2 bis 10 und 12 bis 13.Further advantageous embodiments will become apparent from the claims 2 to 10 and 12 to 13.

Eine besonders vorteilhafte Weiterbildung ist dadurch gegeben, dass die Metallhülse einen zum freien Ende des Bundbolzens gelegenen und nach außen weisenden Kragen besitzt. Dadurch kann die empfindlichere Stirnfläche der Rolle zusätzlich geschützt werden.A particularly advantageous development is given by the fact that the metal sleeve has a collar located to the free end of the collar bolt and facing outward. As a result, the sensitive end face of the roller can be additionally protected.

Ferner ist dabei vorgesehen, dass der Kragen die Stärke der Kunststoffummantelung hat, so dass die Kunststoffummantelung in Richtung der Stirnfläche vollständig abgedeckt ist.Furthermore, it is provided that the collar has the strength of the plastic casing, so that the plastic casing is completely covered in the direction of the end face.

Zur Herstellung der Rolle kann vorgesehen werden, dass die Kunststoffummantelung durch Umspritzen der Metallhülse erzeugt ist. Wenn die Metallhülse mit über die Mantelfläche verteilten Bohrungen versehen ist, in welche die Kunststoffummantelungen zumindest bereichsweise eingreift, kann ein optimaler Verbund der Kunststoffummantelung und der Metallhülse erreicht werden.For the production of the roll can be provided that the plastic casing is produced by encapsulation of the metal sleeve. If the metal sleeve is provided with holes distributed over the lateral surface, in which the plastic sheathing engages at least partially, an optimal combination of the plastic sheath and the metal sleeve can be achieved.

Um die Reibung auch zwischen dem Bundbolzen und der Rolle zu reduzieren kann ferner vorgesehen werden, dass die Kunststoffummantelung im Bereich der Bohrungen über die Innenseite der Metallhülse in Richtung des Bundbolzens vorsteht. Somit wird auch hier ein unmittelbares Zusammenwirken der Metallflächen vermieden.In order to reduce the friction between the collar bolt and the roller can also be provided that the plastic coating protrudes in the region of the holes on the inside of the metal sleeve in the direction of the collar bolt. Thus, a direct interaction of the metal surfaces is also avoided here.

Um die Ummantelung und die Metallhülse auch in Längsrichtung formschlüssig miteinander zu verbinden ist vorgesehen, dass die Metallhülse mit zumindest einer radialen Einschnürung der Mantelfläche versehen ist. Die Einschnürung kann verschiedene Formen haben. Eine besonders bevorzugte Ausgestaltung sieht auch hier einen nach außen weisenden Kragen vor.In order to connect the sheathing and the metal sleeve in the longitudinal direction in a form-fitting manner, it is provided that the metal sleeve is provided with at least one radial constriction of the lateral surface. The Constriction can take many forms. A particularly preferred embodiment also provides an outwardly facing collar here.

Alternativ zum Umspritzen der Metallhülse kann vorgesehen werden, dass die Kunststoffummantelung von einer Kunststoffhülse gebildet wird, welche auf die Rolle drehfest aufgebracht ist. Die Kunststoffhülse kann beispielsweise aufgeschrumpft werden, so dass sich eine fester Sitz der Kunststoffummantelung an der Metallhülse ergibt.Alternatively, for encapsulating the metal sleeve can be provided that the plastic casing is formed by a plastic sleeve, which is rotatably mounted on the role. The plastic sleeve can be shrunk, for example, so that there is a tight fit of the plastic casing on the metal sleeve.

Wenn die Kunststoffummantelung an ihrem vom freien Ende des Bundbolzens wegweisenden Ende eine über den Innendurchmesser der Metallhülse nach innen vorragende Einschnürung aufweist, welche zumindest einer Umfangsnut des Bundbolzens zuordenbar ist, dann kann die Befestigung der Rolle erleichtert werden und ggf. sogar ohne Werkzeug erfolgen.If the plastic casing has at its pointing away from the free end of the collar pin end over the inner diameter of the metal sleeve inwardly projecting constriction which at least one circumferential groove of the collar bolt is assigned, then the attachment of the role can be facilitated and possibly even done without tools.

Für die alternative Lösung nach Anspruch 11 ist auch vorteilhaft, wenn das Sicherungselement aus einer ringförmigen Krone besteht, die mit radial nach innenweisenden Rastvorsprüngen an dem Bundbolzen festlegbar ist. Dadurch wird neben der Befestigung der Rolle an dem Bundbolzen auch ein Schutz der Stirnfläche erreicht.For the alternative solution according to claim 11 is also advantageous if the securing element consists of an annular crown which can be fixed with radially inwardly facing latching projections on the collar bolt. As a result, protection of the end face is achieved in addition to the attachment of the roller to the collar bolt.

Um auch hier eine Verstellung der Rolle relativ zum Bundbolzen zu erreichen kann vorgesehen werden, dass der Bundbolzen mehrere axial benachbarte Umfangsnuten aufweist, denen das Sicherungselement mit den Rastsprüngen zuordenbar ist und dass die Rolle an dem Sicherungselement festgelegt ist.In order to achieve an adjustment of the role relative to the collar bolt here can be provided that the collar bolt has a plurality of axially adjacent circumferential grooves, which the securing element with the locking jumps can be assigned and that the role is fixed to the fuse element.

In der Fig. 1 ist der Rollenbolzen an sich mit 1 und die Rolle mit 2 bezeichnet. Die Rolle 2 ist an dem Bundbolzen 3 befestigt, der einen Befestigungsansatz 4 aufweist, mit dem der Rollenbolzen 1 beispielsweise an der Treibstange eines Treibstangenbeschlages befestigt werden kann. Dem entsprechend ragt das Ende 5 des Rollenbolzens 1 frei nach außen z.B. von einer Falzfläche vor. Wie in Verbindung mit der Fig. 2 deutlich wird, ist der Befestigungsansatz 4 gegenüber dem zylindrischen Abschnitt 6 exzentrisch angeordnet. Wird der Befestigungsansatz 4 beispielsweise in einer Bohrung einer Treibstange verstemmt, kann über diese exzentrische Anordnung eine Andruckverstellung justiert werden. Diesbezüglich wird auf die AT 307 914 verwiesen, auf die betreffend die exzentrische Lagerung de Rollenbolzens 1 vollinhaltlich Bezug genommen wird. Um die Justage vornehmen zu können ist der Rollenbolzen 1 an seinem freien Ende 5 mit einem Werkzeugeingriff 7 versehen.In the Fig. 1 is the roller bolt per se with 1 and the roller designated 2. The roller 2 is fixed to the collar bolt 3, which has a mounting lug 4, with which the roller pin 1 can be attached, for example, to the drive rod of a drive rod fitting. Accordingly, the end 5 of the roller bolt 1 protrudes freely outward, for example, from a rebate surface. As in connection with the Fig. 2 becomes clear, the mounting lug 4 is arranged eccentrically relative to the cylindrical portion 6. If the attachment lug 4 is caulked, for example, in a bore of a drive rod, a pressure adjustment can be adjusted via this eccentric arrangement. In this regard is on the AT 307 914 to which reference is made in full respect to the eccentric bearing of the roller bolt 1. In order to make the adjustment of the roller bolt 1 is provided at its free end 5 with a tool engagement 7.

Ausweislich der Fig. 1 bis 3 besteht die Rolle 2 des Rollenbolzens 1 mit einer aus Kunststoffummantelung 8 und einer Metallhülse 9. Die Metallhülse 9 besitzt einen nach außen weisenden Kragen 10, der die Stirnfläche 11 der Kunststoffummantelung 8 abdeckt. Ferner steht die Kunststoffummantelung 8 an dem zum Befestigungsansatz 4 hinweisenden Ende 12 der Rolle 2 über die Metallhülse 9 über und umgreift einen umlaufenden Vorsprung 13 an dem zylindrischen Abschnitt 6 des Bundbolzens 3. Gleichzeitig liegt die Rolle 2 mit der Metallhülse 9 an dem zum freien Ende 5 gewandten Kante des Vorsprungs 13 an, so dass dieser die Rolle 2 in axialer Richtung 14 sicher hält. Die gewählte Anordnung stellt sicher, dass gegebenenfalls auf die Rolle 2 wirkende Druckkräfte von der Metallhülse 9 aufgenommen und über den Vorsprung 13 übertragen werden können, Druckkräfte in axialer Richtung können beispielsweise dadurch entstehen, dass der Rollenbolzen 1 mit dem Kragen 10 an einen Vorsprung anschlägt, beispielsweise beim Schließen des Flügels oder bei einer Bewegung der Treibstange, welcher der Rollenbolzen zugeordnet ist. Das Anschlagen mit einer Kante der Rolle bewirkt neben einer Belastung in radialer Richtung auch eine Kraftkomponente entgegen der Richtung 14.Evidently the Fig. 1 to 3 the roller 2 consists of the roller bolt 1 with a plastic sheath 8 and a metal sleeve 9. The metal sleeve 9 has an outwardly facing collar 10 which covers the end face 11 of the plastic sheath 8. Furthermore, the plastic sheath 8 protrudes over the metal sleeve 9 at the end 12 of the roller 2 pointing towards the attachment lug 4 and surrounds a circumferential projection 13 on the cylindrical portion 6 of the collar bolt 3. At the same time the roller 2 with the metal sleeve 9 lies against the free end 5 facing edge of the projection 13, so that this securely holds the roller 2 in the axial direction 14. The selected arrangement ensures that optionally acting on the roller 2 compressive forces can be absorbed by the metal sleeve 9 and transmitted via the projection 13, compressive forces in the axial direction For example, may arise because the roller pin 1 with the collar 10 abuts a projection, for example, when closing the wing or during a movement of the drive rod, which is associated with the roller bolt. The impact with an edge of the roller causes not only a load in the radial direction but also a force component counter to the direction 14.

Die Ausgestaltung der Rolle 2 aus der Metallhülse 9 , die von der Kunststoffummantelung 9 übergriffen wird, bietet einerseits den Vorteil der stabilen Ausgestaltung und vermeidet andererseits nahezu das Zusammenwirken von Oberflächen aus Metalls. Bei einem Schließvorgang legt sich der Rollenbolzen 1 mit der Rolle 2 an den, hier nicht dargestellten, Riegelsteg an, ohne dass es zu einer großflächigen Reibung von Metallflächen kommt. Dadurch lassen sich unerwünschte Abriebspuren an dem Riegelstegen vermeiden.The design of the roller 2 of the metal sleeve 9, which is overlapped by the plastic sheath 9, on the one hand offers the advantage of stable design and on the other hand virtually avoids the interaction of surfaces of metal. During a closing operation, the roller pin 1 engages with the roller 2 to the, not shown, locking bar, without causing large-scale friction of metal surfaces. As a result, unwanted traces of abrasion can be avoided on the bar webs.

Durch den Kragen 10 wird dabei eine Beschädigung der Stirnflächen 11 der Kunststoffummantelung 8 verhindert. Der Kragen 10 hat dabei die Stärke der Kunststoffummantelung 8, es kann aber auch vorgesehen werden, dass diese noch über den Kragen 10 vorsteht, um ein Zusammenwirken des Kragens 10 mit dem Riegelsteg zu vermeiden. In der Praxis hat es sich aber gezeigt, dass die Rollenbolzen 2 durch die auftretenden Kräfte beim Auftreffen an dem Riegelsteg geringfügig elastisch verformt wird, so dass der Kragen 10 entweder geringfügig zurücksteht oder aber zumindest die entstehenden Kräfte zwischen dem Kragen 10 und dem Riegelsteg gering sind.By the collar 10 while damage to the end faces 11 of the plastic sheath 8 is prevented. The collar 10 has the strength of the plastic sheath 8, but it can also be provided that this still protrudes beyond the collar 10 in order to avoid interaction of the collar 10 with the locking bar. In practice, it has been shown that the roller pin 2 is slightly elastically deformed by the forces occurring when hitting the locking bar, so that the collar 10 either slightly protrudes or at least the resulting forces between the collar 10 and the locking bar are low ,

In der Einzelteildarstellung der Rolle 2 nach Fig. 3 wird noch erkennbar, dass die Kunststoffummantelung 9 an dem Ende 12 mit einer umlaufenden Rastnase 15 versehen ist, die im montierten Zustand den Vorsprung 13 hintergreift. Die elastischen Eigenschaften der Kunststoffummantelung 9 lassen daher eine einfache Montage oder ggf. Demontage der Rolle 2 zu. Hier ist auch entnehmbar, dass die Metallhülse 9 mit zumindest einer radialen Einschnürung der Mantelfläche 15 versehen ist, die im dargestellten Ausführungsbeispiel dadurch entsteht, dass die Metallhülse 9 an ihrem Ende 16 mit einem zweiten nach außen vorragenden Kragen 17 aufweist. Dadurch entsteht ein in radialer Richtung liegender Hinterschnitt an dem Kragen 17, so dass die Kunststoffummantelung 8 und die Metallhülse 9 auch in axialer Richtung aneinander gesichert sind.In the single part representation of the roll 2 after Fig. 3 will be appreciated that the plastic sheath 9 is provided at the end 12 with a circumferential latching lug 15 which engages behind the projection 13 in the mounted state. The elastic properties of the plastic casing 9 therefore allow a simple assembly or possibly disassembly of the roller 2. Here is also removed that the metal sleeve 9 is provided with at least one radial constriction of the lateral surface 15, which in the illustrated Embodiment arises because the metal sleeve 9 has at its end 16 with a second outwardly projecting collar 17. This results in an undercut located in the radial direction on the collar 17, so that the plastic casing 8 and the metal sleeve 9 are secured to one another in the axial direction.

Besonders vorteilhaft ist dabei eine Ausgestaltung, bei der die Kunststoffummantelung 8 durch Umspritzen der Metallhülse 9 erzeugt ist. Dadurch wird auf einfache und kostengünstige Weise ein fester Verbund der Metallhülse 9 und der Kunststoffummantelung 8 erreicht, der sich wie vorstehend beschrieben auf einfache Weise sichern lässt.Particularly advantageous is an embodiment in which the plastic sheath 8 is produced by encapsulation of the metal sleeve 9. As a result, a solid composite of the metal sleeve 9 and the plastic sheath 8 is achieved in a simple and cost-effective manner, which can be secured in a simple manner as described above.

Hierzu kann entsprechend der Fig. 4 alternativ oder in Verbindung mit den Ausführungsbeispielen nach Fig. 1 bis 3 noch vorgesehen werden, dass die Metallhülse 9 mit über die Mantelfläche 16 verteilten Bohrungen 18 versehen ist, in welche die Kunststoffummantelung 8 zumindest bereichsweise eingreift. Daraus ergibt sich ein Formschluss, der die Verbindung der Kunststoffummantelung 8 und der Metallhülse 9 verstärkt. Hier kann auch vorgesehen werden, dass die Kunststoffummantelung 8 im Bereich der Bohrungen 18 über die Innenseite der Metallhülse 9 in Richtung des Bundbolzens 3 vorsteht, so dass die Metallhülse 9 und der Bundbolzen 3 geringfügig voneinander beabstandet bleiben. Ein unmittelbares Zusammenwirken der Metallflächen wird dadurch vermieden und ggf. bei der Herstellung der Bauteile unvermeidliche Toleranzen lassen sich durch die elastischen Eigenschaften der Kunststoffummantelung 8 ausgleichen.This can be done according to the Fig. 4 alternatively or in conjunction with the embodiments according to Fig. 1 to 3 be provided that the metal sleeve 9 is provided with over the lateral surface 16 distributed holes 18, in which the plastic casing 8 engages at least partially. This results in a positive connection, which reinforces the connection of the plastic casing 8 and the metal sleeve 9. Here it can also be provided that the plastic casing 8 in the region of the bores 18 projects beyond the inside of the metal sleeve 9 in the direction of the collar bolt 3, so that the metal sleeve 9 and the collar bolt 3 remain slightly spaced from each other. A direct interaction of the metal surfaces is thereby avoided and possibly in the manufacture of components unavoidable tolerances can be compensated by the elastic properties of the plastic casing 8.

Alternativ und ohne dass hierzu spezielle Darstellungen notwendig sind kann die Kunststoffummantelung 8 von einer Kunststoffhülse gebildet werden, welche auf die Metallhülse 9 drehfest aufgebracht ist. Dies kann beispielsweise dadurch erfolgen, dass die Kunststoffhülse auf die Metallhülse 9 aufgeschrumpft oder geklebt wird.Alternatively and without the need for special representations are necessary, the plastic sheath 8 can be formed by a plastic sleeve which is rotatably mounted on the metal sleeve 9. This can be done, for example, that the plastic sleeve is shrunk or glued to the metal sleeve 9.

Alternativ zu der Ausgestaltung nach den Fig. 1 bis 4 kann ferner vorgesehen werden, dass die Kunststoffummantelung 8 an ihrem freien Ende 12 mit der über den Innendurchmesser der Metallhülse 9 nach innen vorragende Einschnürung in Form der Rastnase 15 in eine Umfangsnut des Bundbolzens 3 eingreift.Alternatively to the embodiment of the Fig. 1 to 4 can further be provided that the plastic casing 8 engages at its free end 12 with the over the inner diameter of the metal sleeve 9 inwardly projecting constriction in the form of locking lug 15 in a circumferential groove of the collar bolt 3.

In der Fig. 5 ist ein weiteres Ausführungsbeispiel eines Rollenbolzens 1 dargestellt. Hierbei ist der Bundbolzen 3 mit einer umlaufenden Nut 35 versehen, in der ein Spreizring 36 einsitzt. Die Metallhülse 9 der Rolle 2 weist innenseitig zwei versetzt zueinander angeordnete Nuten 37, 38 auf, die zum Eingriff des Spreizrings 36 dienen. Die Nuten 37, 38 sind dabei in einem Abschnitt 39 eingebracht, der gegenüber dem verbleibenden Rest der Metallhülse 9 einen geringeren Innendurchmesser 40 aufweist. Dadurch entsteht eine größere Wandstärke in der Metallhülse 9 im Bereich der Nuten 37, 38, so dass die mechanische Stabilität der Metallhülse 9 trotz der Nuten 37, 38 erhalten bleibt. Der Bundbolzen 3 weist an seinem Ende 5 einen umlaufenden Kragen 41 auf, dessen Außendurchmesser größer bemessen ist, als der Innendurchmesser 40, so dass der Kragen 41 einen Endanschlag für die Rolle 2 in Richtung 14 bildet.In the Fig. 5 Another embodiment of a roller bolt 1 is shown. Here, the collar bolt 3 is provided with a circumferential groove 35 in which a spreader 36 is seated. The metal sleeve 9 of the roller 2 has on the inside two mutually offset grooves 37, 38, which serve to engage the spreader 36. The grooves 37, 38 are introduced in a section 39, which has a smaller inner diameter 40 than the remaining part of the metal sleeve 9. This results in a larger wall thickness in the metal sleeve 9 in the region of the grooves 37, 38, so that the mechanical stability of the metal sleeve 9 is maintained despite the grooves 37, 38. The collar bolt 3 has at its end 5 a circumferential collar 41, whose outer diameter is dimensioned larger than the inner diameter 40, so that the collar 41 forms an end stop for the roller 2 in the direction 14.

Die axiale Abmessung der Metallhülse 9 entspricht in Gegensatz zu den in den Fign. 1 bis 3 dargestellten Ausführungen der Abmessung der Rolle 2, da die axiale Fixierung der Rolle 2 an dem Bundbolzen 3 über den Spreizring 36 erfolgt.The axial dimension of the metal sleeve 9 corresponds in contrast to those in the FIGS. 1 to 3 illustrated embodiments of the dimension of the roller 2, since the axial fixation of the roller 2 takes place on the collar pin 3 via the spreader 36.

Zur Fixierung der Kunststoffummantelung 8 an der Metallhülse 9 ist die Metallhülse 9 an dem Ende 42 mit einer den Außendurchmesser vergrößernden konischen Erweiterung 43 versehen, so dass die Kunststoffummantelung 8 zwischen dem Kragen 10 und der Erweiterung 43 festgelegt ist.For fixing the plastic casing 8 to the metal sleeve 9, the metal sleeve 9 is provided at the end 42 with a conical enlargement 43 enlarging the outside diameter, so that the plastic casing 8 is fixed between the collar 10 and the extension 43.

Die Kunststoffummantelung 8 kann hierbei ebenfalls durch Umspritzen der Metallhülse 9 hergestellt werden. Es ist aber auch möglich und vorteilhaft, die Kunststoffummantelung 8 aus einem Rohrabschnitt zu bilden, der auf der Metallhülse 9 aufgeschrumpft oder aufgeklebt wird.The plastic casing 8 can also be made by encapsulating the metal sleeve 9. But it is also possible and advantageous, the Form plastic casing 8 from a pipe section, which is shrunk or glued to the metal sleeve 9.

Abschließend soll noch darauf hingewiesen werden, dass die Kunststoffummantelungen 8 aller genannten Ausführungsbeispiele aus einem Kunststoff bestehen, dem reibungsmindemde Zusätze beigefügt sind. Dadurch lassen sich die vorteilhaften Eigenschaften der Rolle 2 nochmals verbessern.Finally, it should be noted that the plastic sheaths 8 all the above embodiments consist of a plastic, the friction-reducing additives are attached. As a result, the advantageous properties of the roller 2 can be further improved.
