Description

Die Erfindung betrifft einen Lader mit einem zwischen wenigstens zwei Stellungen beweglichen Bauteil, zur Festlegung des Laders an einem Fahrzeug, und mit einem Gestänge, das einerseits an den Bauteil angeschlossen ist. The invention relates to a loader with at least one two positions movable component, to fix the loader on a vehicle, and with a linkage that on the one hand to the Component is connected.

Die europäische Patentanmeldung 94112909 beschreibt eine in der Betriebsanleitung 440 Loader, John Deere Welland Works, OMW42582 Issue G3 offenbarte Betätigungsvorrichtung für die Verriegelung eines Frontladerrahmens auf einem Frontgewichtsträger eines Ackerschleppers. Danach wird eine als Riegel dienende im Querschnitt L-förmige Platte unter der Wirkung einer Druckfeder in eine Sperrstellung geschwenkt und mittels einer Stange entgegen der Wirkung der Feder in eine Freigabestellung verbracht, in der der Frontlader von dem Ackerschlepper gelöst werden kann. Das Schwenken der Platte in die Verriegelungsstellung setzt voraus, daß die Stange und die Platte ungehindert bewegt werden können, so daß die Feder die Schwenkbewegung vollziehen kann. European patent application 94112909 describes one in the Operating instructions 440 Loader, John Deere Welland Works, OMW42582 Issue G3 disclosed locking mechanism a front loader frame on a front weight carrier Agricultural tractors. Then one serving as a bolt in the Cross section L-shaped plate under the action of a compression spring pivoted into a locked position and by means of a rod against the action of the spring in a release position spent in the front loader detached from the tractor can be. Swiveling the plate into the locked position assumes that the rod and the plate can be moved freely, so that the spring Can perform pivoting movement.

Die NL-C-164 235 offenbart eine Vorrichtung zum Arretieren eines Frontladers auf einem Fahrzeug, wobei eine Zentrieröse in ein Befestigungsmaul einsetzbar und mittels eines Bolzens sicherbar ist. Der Bolzen wird mittels einer Feder in miteinander fluchtende Bohrungen in der Zentrieröse und dem Befestigungsmaul bewegt und mittels eines Seilzugs zurückgezogen, um somit die Zentrieröse freizugeben. Bei diesem Stand der Technik kann nur unmittelbar an dem Befestigungsmaul sicher festgestellt werden, ob der Bolzen alle Bohrungen durchsetzt hat. NL-C-164 235 discloses a device for locking a Front loader on a vehicle, with a centering eye in one Fastening mouth can be used and secured with a bolt is. The bolt is held together by a spring aligned holes in the centering eye and the fastening mouth moved and retracted by means of a cable pull, so that the Release centering eyelet. With this state of the art only can be safely determined directly on the fastening mouth, whether the bolt has penetrated all holes.

Die der Erfindung zugrunde liegende Aufgabe wird darin gesehen, eine Vorrichtung zum Betätigen eines zwischen wenigstens zwei Stellungen beweglichen Bauteils, insbesondere eines Riegels oder dergleichen, unter Verwendung eines Gestänges, das einerseits an den Bauteil angeschlossen ist, vorzuschlagen, die zuverlässig und erkennbar den Bauteil in eine seiner Stellungen bewegt. The object underlying the invention is seen in a device for actuating one between at least two Positions of movable component, in particular a bolt or the like, using a linkage on the one hand the component is connected to propose the reliable and noticeably moved the component into one of its positions.  

Diese Aufgabe wird erfindungsgemäß durch die Lehre des Patentanspruchs 1 gelöst, wobei in den weiteren Patentansprüchen die Lösung in vorteilhafter Weise weiterentwickelnde Merkmale aufgeführt sind. This object is achieved by the teaching of the claim 1 solved, the in the further claims Features that further develop features in an advantageous manner are listed.

Auf diese Weise wird infolge der Zugbewegung auf das Gestänge die Bewegung des Bauteils nicht von der Stärke und Funktion einer Feder abhängig gemacht, sondern durch Betätigen des Gestänges definitiv ausgeführt. Dadurch, daß das Verriegelungsglied Abschnitte unterschiedlicher Abmessungen aufweist, die jeweils bestimmten Bereichen der Führungsbahn zugeordnet sind, ist zudem gewährleistet, daß beim Eintritt der jeweiligen Abschnitte in die entsprechende Bereiche auch ein bestimmte Stellung des Bauteils gegeben ist. In this way, due to the train movement on the linkage the movement of the component does not depend on the strength and function made dependent on a spring, but by pressing the Linkage definitely executed. Because that Locking member sections of different dimensions has, each specific areas of the guideway are also guaranteed that when entering of the respective sections in the corresponding areas as well a certain position of the component is given.

Wenn auch die Führungsbahn eine bestimmte Neigung oder Krümmung gegenüber der Bewegungsrichtung des Gestänges aufweisen könnte, ergibt deren Ausrichtung in der Bewegungsrichtung des Gestänges eine zwangsfreie Bewegung des Gestänges in der Führungsbahn und eine einwandfreie Aufnahme des Verriegelungsglieds in dem Bereich größerer Abmessung. If the guideway also has a certain inclination or Curvature compared to the direction of movement of the boom could have their orientation in the Direction of movement of the boom a positive movement of the Linkage in the guideway and perfect pick-up of the locking member in the area of larger dimensions.

Eine zuverlässige Halterung des Gestänges, die auch bei Erschütterungen oder irrtümlicher Berührung des Gestänges keine Betätigung des Bauteils hervorruft, wird dadurch erreicht, daß das Verriegelungsglied automatisch in den größeren Bereich aufgrund der angreifenden Gewichts- und/oder Federkraft gelangt. Wenn die Bewegung aufgrund einer beliebig ausgebildeten und beliebig angeordneten Feder erfolgt, kann das Verriegelungsglied auch seitwärts oder nach oben in Eingriff mit dem Bereich gebracht werden. Aufgrund der zylindrischen Ausbildung der Abschnitte des Verriegelungsglieds und des Bereichs wird eine zuverlässige Aufnahme ohne Verkantungen des Verriegelungsglieds in dem Bereich der Führungsbahn sichergestellt, wobei unter "zylindrisch" jede Art einer Ausnehmung mit zueinander parallel verlaufenden Seitenkanten zu verstehen ist. A reliable attachment of the boom, which also at Vibrations or erroneous contact with the boom does not cause actuation of the component achieved that the locking member automatically in the larger area due to attacking weight and / or Spring force comes. If the movement is due to any trained and arbitrarily arranged spring, can the locking member also sideways or up in Interference with the area. Due to the cylindrical formation of the sections of the Locking member and the area will be reliable Recording without tilting the locking member in the Area of the guideway ensured, taking under "cylindrical" any kind of a recess with each other parallel side edges is to be understood.  

Durch eine Einstellbarkeit der wirksamen Länge des Gestänges, das sowohl mechanisch als Stange, Seil, Flacheisen oder dergleichen, als Druckmittelsäule oder als Elektromotor mit einem linearen Hub ausgebildet sein kann, ist es möglich, Veränderungen der relativen Lage zwischen dem Bauteil, dem Gestänge und der Führungsbahn auszugleichen, die aufgrund von Verschleiß oder äußeren Beschädigungen herrühren können. By adjusting the effective length of the boom, mechanically as a rod, rope, flat iron or the like, as a pressure medium column or as an electric motor a linear stroke, it is possible Changes in the relative position between the component, the Linkage and the guideway, which due to Wear or external damage can result.

Eine einfache und geschützte Anordnung des Bauteils, dessen Schwenklagerung wie auch der Führungsbahn wird dadurch erreicht, daß deren Aufnahme in oder zwischen biegesteifen Schenkeln des Rahmens des Frontladers oder dergleichen erfolgt. Insbesondere, wenn das Gestänge innerhalb der hohlen Schenkel vorgesehen ist, ist es gegen äußere schädigende Einflüsse gut geschützt. A simple and protected arrangement of the component, its Swivel bearing as well as the guideway is thereby achieved that their inclusion in or between rigid Legs of the frame of the front loader or the like he follows. Especially when the linkage is inside the hollow Thigh is provided, it is damaging to external Influences well protected.

Zur einfacheren Handhabung des Gestänges ist ein Bedienungselement, z. B. in der Art eines Handgriffs, vorgesehen. Andere Bedienungselemente, z. B. Stellhebel oder Pedale sind aber ebenfalls anwendbar. For easier handling of the boom is a Control element, e.g. B. in the manner of a handle, intended. Other controls, e.g. B. lever or Pedals can also be used.

Die Verwendung einer Blattfeder zwischen dem Gestänge und dem Schenkel bewirkt, daß das Gestänge in eine bestimmte Stellung gegenüber dem Schenkel und somit der in ihm vorhandenen Führungsbahn gebracht und damit lagegesichert wird. The use of a leaf spring between the linkage and the Leg causes the linkage to move into a certain position opposite the thigh and thus the one present in it Guideway brought and thus secured position.

Eine vorteilhafte Verwendung des Bauteils ist in der Verriegelung eines Frontladers an einem Ackerschlepper, einem Geländefahrzeug, einem Landschaftspflegefahrzeug, einem Bau- oder Forstfahrzeug oder dergleichen zu sehen, da dort die Gewährleistung einer einwandfreien Befestigung des Frontladers wichtig ist. An advantageous use of the component is in the Locking a front loader on a tractor, one Off-road vehicle, a landscaping vehicle, a construction or Forest vehicle or the like to see, since there the Ensuring the front loader is properly attached important is.

In Figur 1 ist ein U-förmiger Rahmen 10 eines Frontladers in der Art eines Bügels gezeigt, der einen rechten und einen linken Schenkel 12 und 14 enthält. Der Frontlader, von dem der Rahmen 10 einen Teil darstellt, enthält üblicherweise auch einen rechten und einen linken nicht gezeigten Pfosten, die an äußere, rückwärtige Abschnitte der Schenkel 12 und 14 angeschweißt sind und untere Endabschnitte aufweisen, die an entgegengesetzten Seiten eines nicht gezeigten Ackerschleppers auf Konsolen befestigt werden; allerdings ist von dem Ackerschlepper ein dessen Vorderteil bildender Gewichtsträger 15 gezeigt. Der Rahmen 10 besitzt einen U-förmigen Bügelabschnitt 16, der zwischen den vorderen Endabschnitten der Schenkel 12, 14 angeschlossen ist und einen Bauteil 18 aufnimmt, der sich zwischen rechten und linken, aufrechten, jeweils Beine bildenden Platten 20, 22, erstreckt und aus einer Platte mit einem Querschnitt in der Form eines umgekehrten L gebildet ist. Der Bauteil 18 hat die Funktion eines Riegels und ist um eine horizontale Achse schwenkbar angeordnet, die durch axial fluchtende Schwenkbolzen in den Platten 20, 22 definiert wird, von denen allerdings nur der rechte Schwenkbolzen 24 zu sehen ist. Der Bauteil 18 ist zwischen einer in durchgezogenen Linien dargestellten Verriegelungsstellung und einer in unterbrochenen Linien dargestellten Freigabestellung schwenkbar. Wenn der Bauteil 18 die Verriegelungsstellung einnimmt, erstreckt sich ein erster Schenkel 26 von ihm horizontal über den Gewichtsträger 15 und liegt an dessen Deckenfläche an, während ein zweiter Schenkel 30 aufrecht vor dem Gewichtsträger 15 verläuft. In Figure 1, a U-shaped frame 10 of a front loader is in the type of a bracket shown, one right and one contains left leg 12 and 14. The front loader, of which the Frame 10 is a part, usually includes a right and a left post, not shown, on outer, rear portions of legs 12 and 14 are welded and have lower end portions that opposite sides of an agricultural tractor, not shown to be attached to consoles; however, is from that Agricultural tractor a weight carrier forming its front part 15 shown. The frame 10 has a U-shaped Bracket section 16, between the front end sections the leg 12, 14 is connected and a component 18 picks up between right and left, upright, each leg-forming plates 20, 22, extends and from a plate with a cross section in the shape of a reverse L is formed. The component 18 has the function a bolt and can be swiveled around a horizontal axis arranged by axially aligned pivot bolts in the   Plates 20, 22 is defined, of which only the right pivot pin 24 can be seen. The component 18 is between one shown in solid lines Locked position and one in broken lines shown release position pivotable. If component 18 assumes the locking position, a first extends Leg 26 of it horizontally over the weight carrier 15 and lies on the ceiling surface, while a second leg 30 runs upright in front of the weight carrier 15.

Eine erfindungsgemäße Vorrichtung 32 zum Betätigen des Bauteils 18 ist vorgesehen, um eine Bedienungsperson in die Lage zu versetzen, den Bauteil 18 von einer entfernten Stelle nahe oder auf einer Bedienungsplattform des Ackerschleppers, an den der Rahmen 10 lösbar angebracht ist, aus zwischen seiner Verriegelungsstellung und seiner Freigabestellung zu verschwenken. Insbesondere sind der linke und rechte Schenkel 12 und 14 des Rahmens 10 rohrförmig, und der Vorrichtung 32 enthält ein Gestänge 34 in der Art einer zylindrischen Stange, die sich innerhalb des rechten Schenkels 12 befindet; allerdings könnte auch ein Seilzug, eine Flüssigkeitssäule oder dergleichen als Gestänge 34 verwendet werden. Eine Öse 36 bildet das vordere Ende des Gestänges 34 und ist mittels eines Bolzens 38 und eines Sicherungsstifts 40 schwenkbar an das äußere Ende eines Hebelarms 41 angeschlossen, der an den Schwenkbolzen 24 angeschweißt ist und sich von diesem nach oben erstreckt. A device 32 for actuating the Component 18 is provided to an operator in the Able to displace component 18 from a remote location near or on an operating platform of the agricultural tractor, to which the frame 10 is removably attached from between its locking position and its release position swivel. In particular, the left and right legs 12 and 14 of the frame 10 tubular, and the device 32nd contains a rod 34 in the manner of a cylindrical rod, which is located within the right leg 12; however, a cable could also be a liquid column or the like can be used as linkage 34. An eyelet 36 forms the front end of the linkage 34 and is by means of a Bolt 38 and a locking pin 40 pivotally to the outer end of a lever arm 41 connected to the Swivel pin 24 is welded and from this after extends above.

Im folgenden wird auf das in den Figuren 2 bis 4 und insbesondere in den Figuren 3 und 4 Gezeigte Bezug genommen, in denen am besten zu sehen ist, daß ein im wesentlichen zylindrisches Verriegelungsglied 42 an das rückwärtige Ende des Gestänges 34 angeschlossen ist. Im Einzelnen enthält das Verriegelungsglied 42 einen oberen und einen unteren Abschnitt 44 und 46, die in einem zwischen ihnen gelegenen eingeschnürten Abschnitt 48 miteinander verbunden sind, wobei der untere Abschnitt 44 den gleichen Durchmesser wie der obere Abschnitt 46 besitzt und über ein Gewinde auf dem rückwärtigen Ende des Gestänges 34 einstellbar ist. Ein als Handgriff ausgebildetes Bedienungselement 50 in der Form eines abgekröpften Flacheisens ist bei 52 auf die Oberseite des Verriegelungsglieds 42 aufgeschraubt. Die obere Seite des rechten Schenkels 12 des Rahmens 10 ist mit einem eine Führungsbahn 54 bildenden Längsschlitz versehen, die in einen vergrößerten rückwärtigen, in diesem Fall am Ende der Führungsbahn 54 gelegenen Endbereich 56 übergeht. Dieser Endbereich 56 ist derart bemessen, daß er den oberen Abschnitt 46 des Verriegelungsglieds 42 aufnehmen kann, während der verbleibende Teil der Führungsbahn 54 geringfügig größer als der Durchmesser des eingeschnürten Abschnitts 48 bemessen ist, so daß sich letzterer frei entlang der Führungsbahn 54 bewegen kann. Das Bedienungselement 50 dient unter anderem dazu, das Verriegelungsglied 42 innerhalb der Führungsbahn 54 zu halten. Es ist ersichtlich, daß bei Frontladern mit anderen als rohrförmigen Schenkeln 12, 14 oder anderen Rahmenteilen in der Nähe der Bedienungsplattform die Führungsbahn 54 auch in jeder anderen brauchbaren Fläche des dann gegebenen Schenkels eingearbeitet sein könnte. Wenn der Bauteil 18 seine Verriegelungsstellung einnimmt, steht das Gestänge 34 unter Zug oder Spannung, wobei sich das Verriegelungsglied 42 mit seinem oberen Abschnitt 46 in einer arretierenden Stellung in dem vergrößerten rückwärtigen Endbereich 56 der Führungsbahn 54 befindet. In the following, reference is made to that in FIGS. 2 to 4 and 3 and 4 shown in particular, where it’s best to see that an essentially cylindrical locking member 42 at the rear end of the linkage 34 is connected. This includes in detail Locking member 42 has an upper and a lower section 44 and 46, which are in between constricted portion 48 are connected together, wherein the lower section 44 has the same diameter as the upper one Section 46 has and threads on the rear End of the linkage 34 is adjustable. One as a handle   trained control element 50 in the form of a cranked flat iron is at 52 on top of the Screwed locking member 42. The top of the right leg 12 of the frame 10 is with a Provided guideway 54 longitudinal slot, which in a enlarged rear, in this case at the end of the Guide path 54 located end portion 56 passes. This End portion 56 is sized to be the upper portion 46 of the locking member 42 can accommodate during the remaining part of the guideway 54 slightly larger than the diameter of the constricted section 48 is dimensioned, so that the latter freely along the guideway 54th can move. The control element 50 serves, among other things the locking member 42 within the guideway 54 to keep. It can be seen that with front loaders with others as tubular legs 12, 14 or other frame parts in the guideway 54 also in the vicinity of the operating platform any other usable surface of the leg then given could be incorporated. If the component 18 its In the locked position, the linkage 34 is below Train or tension, the locking member 42 with its upper section 46 in a locking position in the enlarged rear end portion 56 of the guideway 54 is located.

Das Gewicht des Gestänges 34 und des Verriegelungsglieds 42 kann grundsätzlich als ausreichend betrachtet werden, den oberen Abschnitt 46 des Verriegelungsglieds 42 in seiner arretierenden Stellung zu halten. Wenn jedoch der Formschluß der Lagesicherung noch verstärkt werden soll, kann eine in diesem Fall als Blattfeder ausgebildete Feder 58 auf das Gestänge 34 montiert, d. h. aufgesetzt, werden, die zwischen der oberen Innenfläche des Schenkels 12 und dem Gestänge 34 wirken kann und einer Aufwärtsbewegung des Verriegelungsglieds 42 widersteht. Im einzelnen wird der rückwärtige Abschnitt der Feder 58 von einem in Seitenansicht U-förmigen Bereich 60 gebildet, dessen Schenkel zueinander fluchtende Bohrungen enthalten, die in sich das Gestänge 34 und zwischen sich den unteren Abschnitt 44 des Verriegelungsglieds 42 aufnehmen. In ihrem nicht gespannten Zustand, wie er in den Figuren 2 und 3 gezeigt ist, weist die Feder 58 einen gerade verlaufenden Zwischenteil 62 auf, der ausgehend von dem vorderen, d. h. in der Zeichnung links gelegenen Schenkel des U-förmigen Bereichs 60 nach oben und vorne abgewinkelt ist. Die Feder 58 hat einen vorderen Endabschnitt, der von einem abgerundeten und gekrümmten Bereich 64 gebildet wird, der die obere Innenfläche des Schenkels 12 berührt und mit einer Gleitnut 66 versehen ist. Die Gleitnut 66 folgt der Form des Gestänges 34 so daß das Gestänge 34 in die Gleitnut 66 eintritt, wenn der Zwischenteil 62 nach unten gelenkt wird, was dann der Fall ist, wenn das Verriegelungsglied 42 angehoben ist, um den eingeschnürten Abschnitt 48 in Eingriff mit dem Rest der Führungsbahn 54 zu bringen, der sich von dem Bereich 56 aus wie in Figur 4 gezeigt nach vorne erstreckt. The weight of the linkage 34 and the locking member 42 can basically be considered sufficient, the upper section 46 of the locking member 42 in its to hold the locking position. However, if the form fit to secure the position even more, one in this case designed as a leaf spring 58 on the Linkage 34 mounted, i. H. put on, that between the upper inner surface of the leg 12 and the linkage 34 can act and an upward movement of the locking member 42 resists. In particular, the rear section of the Spring 58 from an area 60 which is U-shaped in side view formed, the legs of which are aligned holes contain the linkage 34 in itself and between them the receive the lower portion 44 of the locking member 42. In   their untensioned condition, as shown in FIGS. 2 and 3 is shown, the spring 58 has a straight one Intermediate part 62 which, starting from the front, i.e. H. in the left leg of the drawing of the U-shaped area 60 is angled upwards and forwards. The spring 58 has one front end section, which is rounded and curved portion 64 is formed which is the upper inner surface of the leg 12 touches and provided with a sliding groove 66 is. The sliding groove 66 follows the shape of the linkage 34 so that the linkage 34 enters the sliding groove 66 when the Intermediate part 62 is directed downward, which is the case is when the locking member 42 is raised to the constricted portion 48 engages the rest of the Bring guideway 54, which extends from the area 56 extends forward as shown in Figure 4.

Während die Feder 58 bevorzugterweise und wie in der Zeichnung dargestellt als eine Blattfeder ausgebildet ist, mit der das Verriegelungsglied 42 nachgiebig in seiner Verriegelungsstellung gehalten wird, würde stattdessen auch eine Spiralfeder zwischen der oberen Innenfläche des Schenkels 12 und dem unteren Abschnitt 44 des Verriegelungsglieds 42 funktionieren, um das Verriegelungsglied 42 zwangsläufig in der Verriegelungsstellung zu halten. While the spring 58 preferably and as in the drawing shown is designed as a leaf spring with which the Locking member 42 compliant in its Locked position would be held instead a coil spring between the upper inner surface of the leg 12 and the lower portion 44 of the locking member 42 function inevitably into the locking member 42 to keep the locking position.

Das Gestänge 34 kann von dem Bolzen 38 gelöst und in das Verriegelungsglied 42 hinein oder aus diesem herausgeschraubt werden, um dadurch eine Einstellung vorzunehmen, die erforderlich sein könnte, um das Verriegelungsglied 42 in seiner Verriegelungsstellung in dem rückwärtigen Endbereich 56 der Führungsbahn 54 zu positionieren, wenn sich der Bauteil 18 in seiner Verriegelungsstellung befindet. The linkage 34 can be released from the bolt 38 and into the Locking member 42 screwed in or out of this to make an adjustment that may be required to lock the 42 in its locking position in the rear end region 56 to position the guideway 54 when the component 18 is in its locking position.

Um den Bauteil 18 zu lösen und ihm zu ermöglichen, daß er sich in seine Freigabestellung bewegt, ist es nur erforderlich, das Verriegelungsglied 42 gegebenenfalls mittels des Bedienungselements 50 anzuheben, so daß der eingeschnürte Abschnitt 48 in die Ebene der Führungsbahn 54 gerät, und das Verriegelungsglied 42, sowie mit diesem das Gestänge 34 nach vorne zu schieben, wodurch der Bauteil 18 in seine Freigabestellung schwenkt. Wenn der Schenkel 12 nach vorne abfällt, wie dies in der US-A-5,388,950 gezeigt ist, bewirkt das Gewicht des Bauteils 18, des Gestänges 34 und des Verriegelungsglieds 42, daß das Verriegelungsglied 42 in dem vorderen Endbereich der Führungsbahn 54 gehalten wird. Wenn allerdings die Konstruktion des Frontladers derart ist, daß sich die Schenkel 12, 14 der Horizontalen nähern, kann es wünschenswert sein, eine Führungsbahn 54', wie sie in Figur 6 gezeigt ist, vorzusehen. Diese Führungsbahn 54' hat zusätzlich zu einem vergrößerten rückwärtigen Endbereich 56' einen gleichermaßen vergrößerten vorderen Endbereich 68 zur Aufnahme des oberen Abschnitts 46 des Verriegelungsglieds 42. To release the component 18 and allow it to move moved to its release position, it is only necessary that Locking member 42 optionally by means of Lift control 50 so that the constricted Section 48 gets into the plane of the guideway 54, and that Locking member 42, and with this the linkage 34 after   to push forward, causing the component 18 in its Release position pivots. If the leg 12 forward drops, as shown in US-A-5,388,950 the weight of the component 18, the linkage 34 and the Locking member 42 that the locking member 42 in the front end portion of the guide track 54 is held. If however, the construction of the front loader is such that the legs 12, 14 approach the horizontal, it can it would be desirable to have a guideway 54 'as shown in FIG. 6 is shown to be provided. This guideway 54 'also has to an enlarged rear end region 56 ' equally enlarged front end portion 68 for inclusion of the upper portion 46 of the locking member 42.

Es ist daher zu bemerken, daß die Führungsbahn 54 und das Verriegelungsglied 42 zusammenwirken, um ein wirksames Mittel zum Arretieren des Bauteils 18 in seiner Verriegelungsstellung und zur Anzeige bereit zu stellen, anhand der eine Bedienungsperson feststellen kann, wann bzw. ob der Bauteil 18 seine Verriegelungsstellung eingenommen hat. Des weiteren kann die wirksame Länge des Gestänges 34 durch deren Ein- oder Ausschrauben in das bzw. aus dem Verriegelungsglied 42 eingestellt werden, um sicherzustellen, daß der Bauteil 18 sperrt, wenn sich der obere Abschnitt 46 des Verriegelungsglieds 42 in seiner arretierten Stellung in dem vergrößerten rückwärtigen Endbereich 56 der Führungsbahn 54 oder 54' befindet. It should therefore be noted that the guideway 54 and the Interlocking member 42 cooperate to be an effective means for locking the component 18 in its locking position and to provide for display based on the one Operator can determine when or whether component 18 has taken its locking position. Furthermore, the effective length of the linkage 34 by their input or Unscrewing into and out of the locking member 42 be adjusted to ensure that the component 18th locks when the upper section 46 of the Locking member 42 in its locked position in the enlarged rear end region 56 of the guideway 54 or 54 '.

Obwohl die erfindungsgemäße Vorrichtung 32 in Verbindung mit einem Bauteil 18 zum wahlweisen Festlegen des Rahmens 10 eines Frontladers an einem Gewichtsträger 15 beschrieben ist, kann er auch zusammen mit jedem anderen Element verwendet werden, das zwischen zwei Stellungen beweglich ist und von einer entfernten Stelle aus bedient wird, von der aus das Element nicht einsehbar ist. Although the device 32 according to the invention in connection with a component 18 for optionally setting the frame 10 a Front loader on a weight carrier 15 can be described it can also be used with any other element that is movable between two positions and one is operated from a remote location from which the element is not visible.
