So ist es beispielsweise möglich, dass durch die Einstellvorrichtung eine Lage des Möbelbeschlages oder eines Bauteiles des Möbelbeschlages relativ zu einem Möbelteil einstellbar ist. Im Weiteren ist es möglich, dass bei einem als Möbeldämpfer ausgebildeten Möbelbeschlag eine Lage des Möbeldämpfers relativ zu einem Möbelteil undloder ein Dämpfungshub des Möbeldämpfers und/oder eine Dämpfleistung des Möbeldämpfers einstellbar ist. Ferner ist es möglich, dass bei einem als Möbelantrieb ausgebildeten Möbelbeschlages eine Kraft einer Federvorrichtung auf eine Stellarmanordnung des Möbelantriebes zur Kompensation einer Gewichtskraft des zu bewegenden Möbelteiles einstellbar ist.A large number of parameters of the furniture fitting can be specifically influenced by the setting device of a furniture fitting (e.g. furniture drives, furniture hinges or furniture dampers). It is thus possible, for example, for a position of the furniture fitting or of a component of the furniture fitting to be adjustable relative to a furniture part by means of the setting device. Furthermore, it is possible for a furniture fitting designed as a furniture damper to be adjustable for a position of the furniture damper relative to a furniture part and/or a damping stroke of the furniture damper and/or a damping capacity of the furniture damper. Furthermore, it is possible that, in the case of a furniture fitting designed as a furniture drive, a force of a spring device can be adjusted on an actuating arm arrangement of the furniture drive in order to compensate for a weight of the furniture part to be moved.

In der EP 0 952 290 A2 ist ein Möbelantrieb gezeigt, wobei an einer vorderen Stirnseite des Gehäuses ein drehbares Betätigungselement angeordnet ist, durch welches eine auf die Stellarmanordnung wirksame Federkraft einstellbar ist. Ebenso bekannt sind Möbelantriebe, bei welchen das Betätigungselement durch ein Werkzeug von der Seite her zu betätigen ist, so wie es beispielsweise in Fig. 19a der WO 2006/005086 A1 gezeigt ist.In the EP 0 952 290 A2 a furniture drive is shown, with a rotatable actuating element being arranged on a front end face of the housing, by means of which a spring force acting on the actuating arm arrangement can be adjusted. are also known Furniture drives in which the actuating element can be actuated from the side by a tool, as is the case, for example, in FIG. 19a of FIG WO 2006/005086 A1 is shown.

In bestimmten Montagesituationen können sich bei der Einstellung des Betätigungselementes Schwierigkeiten ergeben. Dies ist beispielsweise dann der Fall, wenn der Träger des Möbelbeschlages gegenüber einer Stirnseite eines Möbelkorpus zurückversetzt an einer Seitenwand des Möbelkorpus montiert ist. In einem solchen Fall würde bei der Einstellung des Betätigungselementes mittels eines Schraubendrehers oder mittels eines Akkuschraubers eine Hand einer Person oder das Bohrfutter des Akkuschraubers mit der Seitenwand des Möbelkorpus kollidieren. Gerade bei Möbelbeschlägen, die in den letzten Jahren wesentlich schmaler und damit kompakter geworden sind, ist eine Einstellung in solchen Montagesituationen erheblich erschwert. Möbelbeschläge mit einem drehbar gelagerten Betätigungselement, dessen Drehachse schräg zu einer Befestigungsfläche des Möbelbeschlages verläuft, sind beispielsweise in der WO 2018/060032 A1 , WO 2014/134642 A1 , EP 2 762 666 A1 und der EP 1 707 723 A2 gezeigt.In certain assembly situations, difficulties may arise when adjusting the actuating element. This is the case, for example, when the carrier of the furniture fitting is mounted on a side wall of the furniture body, set back from a front side of a furniture body. In such a case, when adjusting the actuating element using a screwdriver or using a cordless screwdriver, a person's hand or the drill chuck of the cordless screwdriver would collide with the side wall of the furniture body. Especially in the case of furniture fittings, which have become significantly narrower and therefore more compact in recent years, adjustment in such assembly situations is considerably more difficult. Furniture fittings with a rotatably mounted actuator whose axis of rotation runs obliquely to a mounting surface of the furniture fitting are, for example, in WO 2018/060032 A1 , WO 2014/134642 A1 , EP 2 762 666 A1 and the EP 1 707 723 A2 shown.

Aufgabe der vorliegenden Erfindung ist es, einen Möbelbeschlag der eingangs erwähnten Gattung unter Vermeidung der oben diskutierten Nachteile anzugeben.The object of the present invention is to specify a furniture fitting of the type mentioned at the outset while avoiding the disadvantages discussed above.

Dies wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausführungen der Erfindung sind in den abhängigen Ansprüchen definiert. Gemäß der Erfindung ist vorgesehen, dass das Betätigungselement über eine winkelbewegliche Kupplungsvorrichtung, welche vorzugsweise ein Kugelgelenk umfasst, mit dem Gewindeabschnitt gekoppelt ist.According to the invention, this is achieved by the features of patent claim 1 . Further advantageous embodiments of the invention are defined in the dependent claims. According to the invention, it is provided that the actuating element is coupled to the threaded section via an angularly movable coupling device, which preferably comprises a ball and socket joint.

Auf diese Weise kann das Betätigungselement in drei Bewegungsrichtungen rotatorisch gelagert werden und ermöglicht eine Vielzahl an Relativstellungen des Betätigungselementes zur komfortablen und leicht zugänglichen Betätigung.In this way, the actuating element can be rotatably mounted in three directions of movement and enables a large number of relative positions of the actuating element for comfortable and easily accessible actuation.

Die Drehachse des Betätigungselementes ist schräg zu einer Befestigungsfläche des Trägers anordenbar, wobei das Betätigungselement in einem montierten Zustand des Möbelantriebes durch schräges Positionieren eines Werkzeuges am Betätigungselement komfortabel zugänglich und einfach zu betätigen ist. Vorzugsweise ist vorgesehen, dass die Drehachse des Betätigungselementes einen Winkel größer 5° und kleiner 80°, vorzugsweise einen Winkel größer 10° und kleiner 50°, zur wenigstens einen Befestigungsfläche des Trägers einschließt.The axis of rotation of the actuating element can be arranged at an angle to a fastening surface of the carrier, with the actuating element being easily accessible and easy to actuate when the furniture drive is in a mounted state by positioning a tool at an angle on the actuating element. It is preferably provided that the axis of rotation of the actuating element encloses an angle greater than 5° and less than 80°, preferably an angle greater than 10° and less than 50°, to the at least one fastening surface of the carrier.

Erfindungsgemäß ist vorgesehen, dass das Betätigungselement durch die winkelbewegliche Kupplungsvorrichtung so bewegbar ist, dass der Winkel, welchen die Drehachse des Betätigungselementes und die Befestigungsfläche des Trägers zueinander einschließen, vorzugsweise stufenlos, einstellbar ist. Mit anderen Worten ist das Betätigungselement - zusätzlich zur Drehbewegung um die Drehachse - relativ zum Träger innerhalb vorgegebener Grenzen beweglich gelagert, sodass für eine Betätigung des Betätigungselementes mehrere Relativstellungen des Betätigungselementes zur Verfügung stehen.According to the invention it is provided that the actuating element can be moved by the angularly movable coupling device in such a way that the angle between the axis of rotation of the actuating element and the fastening surface of the carrier can be adjusted, preferably steplessly. In other words, the actuating element—in addition to the rotational movement about the axis of rotation—is movably mounted relative to the carrier within predetermined limits, so that several relative positions of the actuating element are available for actuating the actuating element.

Das Betätigungselement kann relativ zum Träger innerhalb vorgegebener Grenzen stufenlos bewegbar gelagert sein. Alternativ ist es möglich, dass das Betätigungselement an zumindest einer oder mehreren vorgegebenen oder vorgebbaren Stellungen positionierbar ist.The actuating element can be mounted so that it can move continuously within predetermined limits relative to the carrier. Alternatively, it is possible for the actuating element to be able to be positioned at at least one or more predetermined or predeterminable positions.

Das Betätigungselement kann eine Werkzeugaufnahme zur Betätigung des Betätigungselement mittels eines Werkzeuges aufweisen. Das Betätigungselement ist durch Ausübung eines Drehmomentes auf die Werkzeugaufnahme mittels eines Werkzeuges, beispielsweise eines Schraubendrehers oder eines Akkuschraubers, antreibbar. Die Werkzeugaufnahme kann beispielsweise eine Kreuzschlitzform (beispielsweise ein Pozidriv-Profil), ein Vierkant-Profil, ein Sechskant-Profil oder einen Sechsrund (beispielsweise ein Torx-Profil) aufweisen.The actuating element can have a tool holder for actuating the actuating element using a tool. The actuating element can be driven by applying a torque to the tool holder using a tool, for example a screwdriver or a cordless screwdriver. The tool holder can, for example, have a cross slot shape (for example a Pozidriv profile), a square profile, a hexagonal profile or a hexalobe (for example a Torx profile).

Das Betätigungselement kann mit einer Welle verbunden sein, welche in einer Ausnehmung formschlüssig mit radialem Spiel gelagert ist.The actuating element can be connected to a shaft which is mounted in a recess in a form-fitting manner with radial play.

Das Betätigungselement kann wenigstens eine Reibfläche aufweisen, über welche das Betätigungselement in zumindest einer Relativstellung selbsthemmend gehalten ist. Zur Verbesserung der Selbsthemmung kann ein Federelement vorgesehen sein, welches die Reibfläche des Betätigungselementes gegen eine korrespondierende Anschlagfläche drückt.The actuating element can have at least one friction surface, via which the actuating element is held in a self-locking manner in at least one relative position. To improve self-locking, a spring element can be provided, which presses the friction surface of the actuating element against a corresponding stop surface.

Der Möbelbeschlag 4 kann eine Stellarmanordnung 6 mit wenigstens einem Stellarm 6a aufweisen, welcher am Träger 5 um eine Drehachse 7 schwenkbar gelagert ist. Im gezeigten Ausführungsbeispiel weist die Stellarmanordnung 6 mehrere schwenkbare Stellarme 6a, 6b, 6c zum Bewegen des bewegbaren Möbelteiles 3 auf. Fig. 1b shows the piece of furniture 1 in a side view, with a carrier 5 of the furniture fitting 4 being fastened to a vertically extending furniture part 2a in the form of a side wall of the furniture body 2 . The furniture fitting 4 can have an actuating arm arrangement 6 with at least one actuating arm 6a which is pivotably mounted on the carrier 5 about an axis of rotation 7 . In the exemplary embodiment shown, the actuating arm arrangement 6 has a plurality of pivotable actuating arms 6a, 6b, 6c for moving the movable furniture part 3.

Fig. 2a zeigt den am vertikal verlaufenden Möbelteil 2a befestigten Möbelbeschlag 4 in Form des Möbelantriebes 4a in einer Seitenansicht. Zur Kraftbeaufschlagung der Stellarmanordnung 6 ist eine Federvorrichtung 8, vorzugsweise mit zumindest einer als Schraubenfeder ausgebildeten Druckfeder, vorgesehen. Durch eine Einstellvorrichtung 9 des Möbelbeschlages 4 ist ein auf die Stellarmanordnung 6 wirkendes Drehmoment der Federvorrichtung 8 einstellbar. Die Federvorrichtung 8 greift an einem Stellteil 12 an, wobei die Lage des Stellteiles 12 in Bezug zu einer Drehachse 15 eines Zwischenhebels 14 durch eine Betätigung der Einstellvorrichtung 9 einstellbar ist. Der Zwischenhebel 14 kann eine Führung 13, beispielsweise in Form eines Langlochs, zur einstellbaren Lagerung des Stellteiles 12 aufweisen. Figure 2a shows the furniture fitting 4 fastened to the vertically extending furniture part 2a in the form of the furniture drive 4a in a side view. A spring device 8, preferably with at least one compression spring designed as a helical spring, is provided for applying force to the actuating arm arrangement 6. A torque of the spring device 8 acting on the actuating arm arrangement 6 can be adjusted by means of an adjustment device 9 of the furniture fitting 4 . The spring device 8 acts on an actuating part 12 , the position of the actuating part 12 being adjustable in relation to an axis of rotation 15 of an intermediate lever 14 by actuating the adjusting device 9 . The intermediate lever 14 can have a guide 13, for example in the form of an elongated hole, for the adjustable mounting of the actuating part 12.

Fig. 2b zeigt den in Fig. 2a eingerahmten Bereich in einer vergrößerten Ansicht. Die Einstellvorrichtung 9 weist zumindest ein drehbar gelagertes Betätigungselement 16 auf, wobei durch eine Drehung des Betätigungselementes 16 mittels eines Werkzeuges 17 (Fig. 3a, 3b) eine Lage des Stellteiles 12 in oder entlang der Führung 13 des Zwischenhebels 14 und damit ein wirksames Drehmoment der Federvorrichtung 8 auf die Stellarmanordnung 6 einstellbar ist. Der Möbelbeschlag 4 weist einen Übertragungsmechanismus zum Übertragen einer Kraft von der Federvorrichtung 8 auf die Stellarmanordnung 6 auf, wobei der Übertragungsmechanismus eine Steuerkurve 10 und eine von der Federvorrichtung 8 belastete Druckrolle 11 aufweist. Die Druckrolle 11 ist bei einer Bewegung der Stellarmanordnung 6 entlang der Steuerkurve 10 verfahrbar. Im gezeigten Ausführungsbeispiel ist die Druckrolle 11 am Zwischenhebel 14 drehbar gelagert, während die Steuerkurve 10 an dem um die Drehachse 7 schwenkbaren Stellarm 6a angeordnet oder ausgebildet ist. In mechanischer Umkehr ist es auch möglich, die Druckrolle 11 am Stellarm 6a und die Steuerkurve 10 am Zwischenhebel 14 anzuordnen. Figure 2b shows the in Figure 2a framed area in an enlarged view. The adjustment device 9 has at least one rotatably mounted actuating element 16, with rotation of the actuating element 16 by means of a tool 17 ( Figures 3a, 3b ) A position of the actuating part 12 in or along the guide 13 of the intermediate lever 14 and thus an effective torque of the spring device 8 on the actuating arm arrangement 6 can be adjusted. The furniture fitting 4 has a transmission mechanism for transmitting a force from the spring device 8 to the actuating arm arrangement 6 , the transmission mechanism having a cam 10 and a pressure roller 11 loaded by the spring device 8 . The pressure roller 11 can be moved along the cam 10 when the actuating arm arrangement 6 moves. In the exemplary embodiment shown, the pressure roller 11 is rotatably mounted on the intermediate lever 14, while the control cam 10 is arranged or formed on the actuating arm 6a, which can be pivoted about the axis of rotation 7. In mechanical reversal, it is also possible to arrange the pressure roller 11 on the actuating arm 6a and the cam 10 on the intermediate lever 14.

Fig. 3a zeigt den Möbelbeschlag 4 in Form des Möbelantriebes 4a in einer perspektivischen Ansicht. Der Träger 5 des Möbelbeschlages 4 ist vorzugsweise im Wesentlichen quaderförmig ausgebildet und weist wenigstens eine Befestigungsfläche 5a, 5b zur Befestigung an einem Möbelteil 2a auf. Die Befestigungsflächen 5a, 5b sind jeweils im Wesentlichen eben ausgebildet und im Wesentlichen parallel voneinander beabstandet, wobei der Möbelbeschlag 4 über die erste Befestigungsfläche 5a an einem ersten (rechten) Möbelteil 2a und über die zweite Befestigungsfläche 5b an einem dem ersten Möbelteil 2a gegenüberliegenden zweiten (linken) Möbelteil 2a zu befestigen ist. Im gezeigten Ausführungsbeispiel ist der um die Drehachse 7 schwenkbare Stellarm 6a mit einem weiteren Stellarm 6b, 6c der Stellarmanordnung 6 lösbar verriegelbar, wobei der weitere Stellarm 6b, 6c mit dem bewegbaren Möbelteil 3 zu verbinden ist. Durch ein Werkzeug 17, beispielsweise einen Schraubendreher, kann das Betätigungselement 16 der Einstellvorrichtung 9 rotiert werden, wodurch ein auf die Stellarmanordnung 6 wirkendes Drehmoment der Federvorrichtung 8 einstellbar ist. Figure 3a shows the furniture fitting 4 in the form of the furniture drive 4a in a perspective view. The carrier 5 of the furniture fitting 4 is preferably essentially cuboid and has at least one fastening surface 5a, 5b for fastening to a furniture part 2a. The fastening surfaces 5a, 5b are each essentially flat and spaced apart from one another essentially in parallel, the furniture fitting 4 being fastened to a first (right) furniture part 2a via the first fastening surface 5a and to a second (right) part 2a opposite the first furniture part 2a via the second fastening surface 5b. left) furniture part 2a is to be attached. In the exemplary embodiment shown, the actuating arm 6a, which can be pivoted about the axis of rotation 7, can be releasably locked to a further actuating arm 6b, 6c of the actuating arm arrangement 6, with the further actuating arm 6b, 6c being able to be connected to the movable furniture part 3. A tool 17, for example a screwdriver, can be used to rotate the actuating element 16 of the adjustment device 9, as a result of which a torque of the spring device 8 acting on the actuating arm arrangement 6 can be adjusted.

Der Träger 5 kann eine vordere Stirnseite und eine untere Längsseite aufweisen, wobei das Betätigungselement 16 vorzugsweise im Bereich der vorderen Stirnseite, der unteren Längsseite oder im Bereich der Befestigungsflächen 5a, 5b angeordnet sein kann.The carrier 5 can have a front face and a lower longitudinal side, wherein the actuating element 16 can preferably be arranged in the area of the front face, the lower longitudinal side or in the area of the fastening surfaces 5a, 5b.

Fig. 3b zeigt den Möbelbeschlag 4, welcher über die erste Befestigungsfläche 5a des Trägers 5 am Möbelteil 2a montiert ist. Das Betätigungselement 16 ist um eine Drehachse 18 rotierbar gelagert, wobei die Drehachse 18 des Betätigungselementes 16 einen Winkel (α) größer 0° und kleiner 90°, vorzugsweise größer 5° und kleiner 80°, vorzugsweise größer 10° und kleiner 50°, zur wenigstens einen Befestigungsfläche 5a des Trägers 5 einschließt. Auf diese Weise kann vermieden werden, dass der Griff des Werkzeuges 17 oder die Hand eines Benutzers, welche bei einer Betätigung des Betätigungselementes 16 den Griff des Werkzeuges 17 umschließt, mit dem Möbelteil 2a kollidiert. Auf diese Weise kann der Bedienkomfort des Betätigungselementes 16 verbessert werden. Dies ist insbesondere auch dann von Vorteil, wenn die Befestigungsflächen 5a, 5b aus Gründen einer kompakten Bauweise des Möbelbeschlages 4 einen relativ geringen Abstand zueinander aufweisen. Figure 3b shows the furniture fitting 4, which is mounted on the first fastening surface 5a of the carrier 5 on the furniture part 2a. Actuating element 16 is mounted such that it can rotate about an axis of rotation 18, with axis of rotation 18 of actuating element 16 forming an angle (α) greater than 0° and less than 90°, preferably greater than 5° and less than 80°, preferably greater than 10° and less than 50°, to at least one attachment surface 5a of the carrier 5 includes. In this way it can be avoided that the handle of the tool 17 or the hand of a user, which encloses the handle of the tool 17 when the actuating element 16 is actuated, collides with the furniture part 2a. In this way, the ease of use of the actuating element 16 can be improved. This is particularly advantageous when the fastening surfaces 5a, 5b have a relatively small distance from one another for reasons of a compact design of the furniture fitting 4.

Das Betätigungselement 16 ist an zumindest einer oder mehreren vorgegebenen oder vorgebbaren Stellungen innerhalb des Winkels (α) positioniert oder positionierbar. Gemäß einem Ausführungsbeispiel kann vorgesehen sein, dass das Betätigungselement 16 innerhalb des definierten Winkels (α) stufenlos bewegbar ist, wobei einem Benutzer für eine Drehung des Betätigungselementes 16 um die Drehachse 18 eine Vielzahl von Positionen zur Verfügung stehen. Das Betätigungselement 16 ist an einer winkelbeweglichen Kupplungsvorrichtung 20 (Fig. 5a), welche vorzugsweise ein Kugelgelenk umfasst, gelagert. Damit das Betätigungselement 16 in einer Relativstellung selbsthemmend gehalten ist, kann zumindest eine Reibfläche 23a (Fig. 5a) vorgesehen sein.The actuating element 16 is or can be positioned at at least one or more predetermined or predetermined positions within the angle (α). According to an exemplary embodiment, it can be provided that the actuating element 16 can be moved steplessly within the defined angle (α), with a large number of positions being available to a user for rotating the actuating element 16 about the axis of rotation 18 . The actuating element 16 is attached to an angularly movable coupling device 20 ( Figure 5a ), Which preferably comprises a ball joint, mounted. At least one friction surface 23a ( Figure 5a ) be provided.

Das Betätigungselement 16 kann in einem bestimmungsgemäß montierten Zustand des Möbelbeschlages 4 dem bewegbaren Möbelteil 3 zugewandt und in einem vorderen Bereich des Trägers 5 angeordnet sein. Auf diese Weise ist das Betätigungselement 16 in einem montierten Zustand des Möbelbeschlages 4 durch das Werkzeug 17 bequem von vorne her zu betätigen.When the furniture fitting 4 is installed as intended, the actuating element 16 can face the movable furniture part 3 and be arranged in a front area of the carrier 5 . In this way, the actuating element 16 can be actuated conveniently from the front by the tool 17 when the furniture fitting 4 is in a mounted state.

Fig. 4 zeigt den als Möbelantrieb 4a ausgebildeten Möbelbeschlag 4 in einer Explosionsansicht. Der Träger 5 weist zwei voneinander beabstandete Befestigungsflächen 5a, 5b zur Befestigung an einem Möbelteil 2a auf, wobei die Federvorrichtung 8 zur Kraftbeaufschlagung des Stellarmes 6a und die Einstellvorrichtung 9 zur Einstellung einer Kraft der Federvorrichtung 8 auf den Stellarm 6a zwischen den Befestigungsflächen 5a, 5b angeordnet sind. Die Federvorrichtung 8 kann zumindest eine oder mehrere Druckfedern aufweisen, welche sich an einem durch die Einstellvorrichtung 9 einstellbaren Stellteil 12 abstützen. Durch eine Drehung des Betätigungselementes 16 um die Drehachse 18 (Fig. 3b) ist das Stellteil 12 in einer ersten Richtung zur Drehachse 15 des Zwischenhebels 14 hin und in einer zweiten Richtung von der Drehachse 15 des Zwischenhebels 14 weg bewegbar. Auf diese Weise ist das von der Federvorrichtung 8 ausgeübte Drehmoment auf den Stellarm 6a einstellbar. 4 shows the furniture fitting 4 designed as a furniture drive 4a in an exploded view. The carrier 5 has two spaced-apart fastening surfaces 5a, 5b for fastening to a piece of furniture 2a, with the spring device 8 for applying a force to the actuating arm 6a and the adjusting device 9 for setting a force of the spring device 8 on the actuating arm 6a between the fastening surfaces 5a, 5b are. The spring device 8 can have at least one or more compression springs, which are supported on an adjusting part 12 that can be adjusted by the adjusting device 9 . By rotating the actuating element 16 about the axis of rotation 18 ( Figure 3b ) the actuating part 12 can be moved in a first direction towards the axis of rotation 15 of the intermediate lever 14 and away from the axis of rotation 15 of the intermediate lever 14 in a second direction. In this way, the torque exerted by the spring device 8 on the actuating arm 6a can be adjusted.

Das Betätigungselement 16 ist über eine winkelbewegliche Kupplungsvorrichtung 20 mit einem Gewindeabschnitt 19 verbunden, wobei der Gewindeabschnitt 19 durch eine Drehung des Betätigungselementes 16 rotierbar ist. Das Stellteil 12 steht mit dem Gewindeabschnitt 19 in Gewindeeingriff, wobei das Stellteil 12 durch eine Drehung des Betätigungselementes 16 entlang des Gewindeabschnitts 19 bewegbar ist. Der Gewindeabschnitt 19 weist eine Längsachse auf, welche im Wesentlichen parallel zur wenigstens einen Befestigungsfläche 5a, 5b des Trägers 5 ausgerichtet sein kann. Am Zwischenhebel 14 ist die Druckrolle 11 drehbar gelagert, welche bei einer Bewegung des Stellarmes 6a um die Drehachse 7 entlang der Steuerkurve 10 des Stellarmes 6a verfahrbar ist.The actuating element 16 is connected to a threaded section 19 via an angularly movable coupling device 20 , the threaded section 19 being rotatable by rotation of the actuating element 16 .

The threaded section 19 has a longitudinal axis which can be aligned essentially parallel to the at least one fastening surface 5a, 5b of the carrier 5. The pressure roller 11 is rotatably mounted on the intermediate lever 14 and can be moved about the axis of rotation 7 along the cam 10 of the adjusting arm 6a when the adjusting arm 6a moves.

Fig. 5a zeigt das Betätigungselement 16, welches über die winkelbewegliche Kupplungsvorrichtung 20 mit dem Gewindeabschnitt 19 zur einstellbaren Lagerung des Stellteiles 12 gekoppelt ist. Das Betätigungselement 16 kann eine Werkzeugaufnahme 22 zur Betätigung des Betätigungselementes 16 mittels eines Werkzeuges 17 aufweisen. Zur bereichsweisen Lagerung des Betätigungselementes 16 ist ein Gehäuse 21 vorgesehen, in welchem die winkelbewegliche Kupplungsvorrichtung 20 aufgenommen ist. Figure 5a shows the actuating element 16, which is coupled via the angularly movable coupling device 20 to the threaded section 19 for the adjustable mounting of the actuating part 12. The actuating element 16 can have a tool holder 22 for actuating the actuating element 16 using a tool 17 . A housing 21, in which the angularly movable coupling device 20 is accommodated, is provided for the regional storage of the actuating element 16.

Fig. 5b zeigt einen Querschnitt der Fig. 5a in einer ersten Stellung des Betätigungselementes 16. Das Betätigungselement 16 ist mit einer Welle 24 verbunden, welche in einer Ausnehmung 25 formschlüssig mit radialem Spiel gelagert ist. Das Betätigungselement 16 kann wenigstens eine, vorzugsweise kugelsegmentförmige, Reibfläche 23a aufweisen, über welche das Betätigungselement 16 in zumindest einer Relativstellung selbsthemmend gehalten ist. In der gezeigten Figur wirkt die mit dem Betätigungselement 16 verbundene Reibfläche 23a mit einer korrespondierenden Anschlagfläche 23b des Gehäuses 21 zusammen. Zur Winkelbegrenzung des Betätigungselementes 16 ist wenigstens ein Anschlag 26a, 26b vorgesehen, welche im gezeigten Ausführungsbeispiel jeweils am Gehäuse 21 angeordnet sind. Figure 5b shows a cross section of the Figure 5a in a first position of the actuating element 16. The actuating element 16 is connected to a shaft 24 which is mounted positively in a recess 25 with radial play. The actuating element 16 can have at least one friction surface 23a, preferably in the shape of a segment of a sphere, via which the actuating element 16 is held in a self-locking manner in at least one relative position. In the figure shown, the friction surface 23a connected to the actuating element 16 interacts with a corresponding stop surface 23b of the housing 21 . To limit the angle of the actuating element 16, at least one stop 26a, 26b is provided, which is arranged on the housing 21 in the exemplary embodiment shown.

Der Gewindeabschnitt 19 weist eine Längsachse (L) auf, wobei die Drehachse 18 des Betätigungselementes 16 und die Längsachse (L) des Gewindeabschnitts 19 nicht-parallel zueinander verlaufen. Beispielsweise kann vorgesehen sein, dass die Drehachse 18 des Betätigungselementes 16 und die Längsachse (L) des Gewindeabschnitts 19 einen Winkel zwischen 10° und 60° zueinander einschließen.The threaded portion 19 has a longitudinal axis (L), wherein the axis of rotation 18 of the actuator 16 and the longitudinal axis (L) of the threaded portion 19 are non-parallel to each other. For example, it can be provided that the axis of rotation 18 of the actuating element 16 and the longitudinal axis (L) of the threaded section 19 enclose an angle of between 10° and 60° to one another.

Fig. 5c zeigt einen Querschnitt der Fig. 5a in einer zweiten Stellung des Betätigungselementes 16. In der gezeigten Figur liegt das Betätigungselement 16 am Anschlag 26a an, sodass eine weitere Schwenkbewegung (d.h. eine Überschreitung des maximal zulässigen Winkels (α)) des Betätigungselementes 16 verhindert ist. Zu erkennen ist, dass die Lage der Drehachse 18 in Fig. 5b und die Lage der Drehachse 18 in Fig. 5c voneinander abweichen. Figure 5c shows a cross section of the Figure 5a in a second position of the actuating element 16. In the figure shown, the actuating element 16 rests against the stop 26a, so that further pivoting movement (ie exceeding the maximum permissible angle (α)) of the actuating element 16 is prevented. It can be seen that the position of the axis of rotation 18 in Figure 5b and the position of the axis of rotation 18 in Figure 5c differ from each other.

Fig. 6 zeigt die Ausführungsform gemäß den Fig. 5a-5c in einer Explosionsansicht. Der Gewindeabschnitt 19 weist einen Endbereich mit der Ausnehmung 25 auf, in welcher die Welle 24 des Betätigungselementes 16 formschlüssig mit radialem Spiel aufnehmbar ist. Das Gehäuse 21 weist zwei miteinander verbindbare Halbschalen 21a, 21b auf, zwischen denen das Betätigungselement 16 mit der Reibfläche 23a aufgenommen ist. Durch ein Federelement 27, beispielsweise in Form einer Druckfeder, ist die Reibfläche 23a des Betätigungselementes 16 gegen die Anschlagfläche 23b des Gehäuses 21, vorzugsweise der Halbschalen 21a, 21b, drückbar, wodurch die Selbsthemmung des Betätigungselementes 16 verbessert ist. 6 shows the embodiment according to FIGS Figures 5a-5c in an exploded view. The threaded section 19 has an end region with the recess 25 in which the shaft 24 of the actuating element 16 can be accommodated in a form-fitting manner with radial play. The housing 21 has two half-shells 21a, 21b which can be connected to one another and between which the actuating element 16 is accommodated with the friction surface 23a. A spring element 27, for example in the form of a compression spring, can be used to press the friction surface 23a of the actuating element 16 against the stop surface 23b of the housing 21, preferably the half-shells 21a, 21b, which improves the self-locking of the actuating element 16.
