Description
Die Erfindung betrifft einen Multifunktionshebel für ein Flurförderzeug mit einem um mindestens eine erste Achse schwenkbaren Hebel und mindestens einem an dem Hebel angeordneten Bedienelement, wobei durch Schwenken des Hebels um die erste Achse und durch Betätigen des Bedienelements jeweils mindestens eine Funktion des Flurförderzeugs steuerbar ist.The invention relates to a multi-function lever for an industrial truck with a at least a first axis pivotable lever and at least one on the Lever arranged control element, whereby by pivoting the lever around the first axis and by actuating the control element at least one each Function of the truck is controllable.
Multifunktionshebel der genannten Art werden in Flurförderzeugen in der Regel zur Steuerung von verschiedenen Funktionen einer Lastaufnahmevorrichtung eingesetzt. Beispielsweise kann die Lastaufnahmevorrichtung in vertikaler Richtung auf- und abbewegt werden. Gemäß einer anderen Funktion kann die Lastaufnahmevorrichtung um eine horizontale Achse geneigt werden. Ebenfalls bekannt ist es, die Lastaufnahmevorrichtung in einer oder zwei Richtungen horizontal verschiebbar auszuführen.Multi-function levers of the type mentioned are generally used in industrial trucks Control of various functions of a load suspension device used. For example, the load suspension device can be opened and closed in the vertical direction be moved. According to another function, the load suspension device can be inclined about a horizontal axis. It is also known that Load suspension device horizontally displaceable in one or two directions to execute.
Multifunktionshebel werden eingesetzt, um einer Bedienperson ein aufeinanderfolgendes oder gleichzeitiges Betätigen verschiedener Funktionen des Flurförderzeugs zu ermöglichen, ohne ein Umgreifen zwischen verschiedenen herkömmlichen Bedienhebel zu erfordern. Mit einem einzigen Multifunktionshebel können also mindestens zwei Funktionen des Flurförderzeugs gesteuert werden.Multi-function levers are used to one operator successive or simultaneous operation of various functions of the To enable the truck without changing hands to require conventional operating lever. With a single multi-function lever So at least two functions of the truck can be controlled.
Um die Gefahr einer Fehlbedienung des Flurförderzeugs möglichst gering zu halten, wird angestrebt, die erforderliche Betätigungsrichtung des Hebels oder des Bedienelements möglichst funktionslogisch zu der zu steuemden Funktion des Flurförderzeugs anzuordnen. Ein weiteres Ziel bei der Gestaltung von Multifunktionshebeln ist es, eine sequentielle oder gleichzeitige Betätigung der verschiedenen Funktionen in ergonomisch vorteilhafter Weise zu ermöglichen. Bekannte Multifunktionshebel können die obengenannten Zielsetzungen nicht vollständig zufriedenstellend erfüllen. To minimize the risk of incorrect operation of the truck, is aimed at the required direction of actuation of the lever or Control element as functionally logical as possible to the function of the To arrange the truck. Another goal in designing Multi-function levers are used to operate the sequential or simultaneous to enable various functions in an ergonomically advantageous manner. Known multi-function levers cannot achieve the above objectives completely satisfactory.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Multifunktionshebel der eingangs genannten Art zur Verfügung zu stellen, bei dem die wichtigsten Funktionen in ergonomisch vorteilhafter Weise funktionslogisch steuerbar sind.The present invention is therefore based on the object To provide multi-function lever of the type mentioned, in which the most important functions can be controlled functionally in an ergonomically advantageous manner are.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Bedienelement durch Schwenken um eine zweite Achse betätigbar ist, wobei die zweite Achse im wesentlichen parallel zur ersten Achse ist. Durch diese Anordnung des Bedienelements wird erreicht, daß mit dem Multifunktionshebel zwei Funktionen gesteuert werden können, die funktionslogisch in der gleichen Richtung zu betätigen sind. Die beiden Achsen sind dabei insbesondere in Ruhestellung des Multifunktionshebels zueinander parallel. Beispielsweise bei Betätigung einer dritten Funktion kann es jedoch vorkommen, daß die beiden Achsen zueinander geneigt werden, so daß sie nicht mehr exakt parallel sind. Die funktionslogische Zuordnung der Betätigungsrichtungen zu den zu steuernden Funktionen bleibt jedoch dabei erhalten.This object is achieved in that the control element by Swiveling about a second axis can be actuated, the second axis in the is substantially parallel to the first axis. By this arrangement of the Control element is achieved with the multi-function lever two functions can be controlled to operate functionally in the same direction are. The two axes are particularly in the rest position of the Multi-function lever parallel to each other. For example, when operating a third Function, however, it can happen that the two axes are inclined to each other so that they are no longer exactly parallel. The functional logic assignment however, the directions of actuation to the functions to be controlled remain receive.
Besonders vorteilhaft ist es, wenn das Bedienelement mit dem Zeigefinger einer den Handgriff greifenden Hand betätigbar ist. Insbesondere mit dem Zeigefinger ist ein feinfühliges Betätigen des Bedienelements möglich, so daß das Bedienelement auch zur Erzeugung von mehrstufigen oder stufenlosen Steuersignalen verwendet werden kann.It when the control element with the index finger of a Handle gripping hand is actuated. Especially with the index finger is a sensitive operation of the control element possible, so that the control element too can be used to generate multi-stage or stepless control signals can.
Eine ergonomisch günstige Anordnung ergibt sich, wenn das Bedienelement auf der einer Bedienperson abgewandten Seite des Hebels angeordnet ist. Die Bedienperson kann bei dieser Anordnung den Hebel mit der Hand greifen, wodurch sich bei natürlicher Handhaltung der Zeigefinger automatisch im Bereich des Bedienelements befindet.An ergonomically favorable arrangement results when the control element on the an operator facing away from the lever is arranged. The operator can grasp the lever with this arrangement by hand, making itself natural hand position of the index finger automatically in the area of the control element located.
Wenn das Flurförderzeug eine in vertikaler Richtung bewegbare Lastaufnahmevorrichtung aufweist, ist die vertikale Bewegung der Lastaufnahmevorrichtung zweckmäßigerweise durch Schwenken des Hebels um die erste Achse steuerbar. Das Heben und Senken der Lastaufnahmevorrichtung ist von der Bedienperson somit durch Bewegen der gesamten Hand steuerbar. If the truck is movable in a vertical direction Has load suspension device, the vertical movement of the Load suspension device expediently by pivoting the lever around first axis controllable. The lifting and lowering of the load handler is from the operator can thus be controlled by moving the entire hand.
Eine funktionslogische und der üblichen Konvention entsprechende Zuordnung der Bewegungsrichtungen von Hebel und Lastaufnahmevorrichtung liegt vor, wenn einem Schwenken des Hebels in Richtung auf die Lastaufnahmevorrichtung zu eine vertikale Abwärtsbewegung der Lastaufnahmevorrichtung zugeordnet ist und einem Schwenken des Hebels in Richtung von der Lastaufnahmevorrichtung weg eine vertikale Aufwärtsbewegung der Lastaufnahmevorrichtung zugeordnet ist.A functional logic and the usual convention assignment of Direction of movement of the lever and load suspension device is when one Swiveling the lever towards the load suspension device to a vertical Downward movement of the load suspension device is assigned and one Swiveling the lever in the direction away from the load suspension device vertical upward movement of the load suspension device is assigned.
Wenn das Flurförderzeug eine um eine horizontale Neigeachse neigbare Lastaufnahmevorrichtung aufweist ist es zweckmäßig, wenn das Neigen der Lastaufnahmevorrichtung durch Schwenken des Bedienelements um die zweite Achse steuerbar ist. Das Neigen der Lastaufnahmevorrichtung ist somit von der Bedienperson mit dem Zeigefinger der den Griff fassenden Hand steuerbar.If the truck is tiltable about a horizontal tilt axis Load suspension device, it is useful if the inclination of the Load suspension device by pivoting the control element around the second Axis is controllable. The inclination of the load suspension device is thus of the Operator can be controlled with the index finger of the hand gripping the handle.
Diese Anordnung ist besonders dann zweckmäßig, wenn die zweite Achse im wesentlichen parallel zu der horizontalen Neigeachse angeordnet ist und einer Schwenkbewegung des Bedienelements eine Neigebewegung der Lastaufnahmevorrichtung in die entsprechende Richtung zugeordnet ist.This arrangement is particularly useful when the second axis in is arranged substantially parallel to the horizontal tilt axis and one Swiveling movement of the control element a tilting movement of the Load suspension device is assigned in the corresponding direction.
Weiterhin ist es möglich, daß durch Schwenken des Hebels um eine dritte Achse eine dritte Funktion des Flurförderzeugs steuerbar ist, wobei die dritte Achse im wesentlichen senkrecht zu der ersten Achse angeordnet ist. Zur Steuerung der dritten Funktion bewegt die Bedienperson den Hebel somit aus ihrer Sicht nach links oder rechts.Furthermore, it is possible that by pivoting the lever about a third axis third function of the truck is controllable, the third axis in is arranged substantially perpendicular to the first axis. To control the third Function, the operator moves the lever to the left or from their point of view right.
Insbesondere, wenn das Flurförderzeug eine in Querrichtung des Flurförderzeugs verschiebbare Lastaufnahmevorrichtung aufweist, ist es zweckmäßig, wenn das Verschieben der Lastaufnahmevorrichtung durch Schwenken des Hebels um die dritte Achse steuerbar ist.In particular, if the industrial truck is in the transverse direction of the industrial truck has displaceable load suspension device, it is advantageous if that Moving the load suspension device by pivoting the lever by the third Axis is controllable.
Gemäß einer vorteilhaften Ausgestaltungsform, der Erfindung ist bei Betätigung des Bedienelements in Abhängigkeit von dem Schwenkwinkel des Bedienelements eine bestimmte Neigegeschwindigkeit der Lastaufnahmevorrichtung vorgebbar. Hierbei ist für das Bedienelement eine Neutralstellung vorgesehen und das Bedienelement weist Mittel zum Erzeugen einer Rückstellkraft in Richtung der Neutralstellung auf. Wenn die Bedienperson das Bedienelement nicht betätigt, ist hierdurch sichergestellt, daß sich das Bedienelement in Neutralstellung befindet und keine Neigebewegung der Lastaufnahmevorrichtung stattfindet.According to an advantageous embodiment, the invention is when the Control element depending on the pivoting angle of the control element certain inclination speed of the load suspension device can be specified. Here is a neutral position is provided for the control element and the control element has Means for generating a restoring force in the direction of the neutral position. If the operator does not operate the control element, this ensures that the control element is in neutral position and no tilting movement of the Load suspension device takes place.
Gemäß einer anderen Ausgestaltung der Erfindung ist bei Betätigung des Bedienelements in Abhängigkeit von dem Schwenkwinkel des Bedienhebels ein bestimmter Sollwert für die Neigung der Lastaufnahmevorrichtung vorgebbar. Weiterhin ist ein Mittel zum Erfassen der tatsächlichen Neigung der Lastaufnahmevorrichtung vorgesehen. Es ist darüber hinaus ein Stellglied, beispielsweise ein Hydraulikzylinder, zum Erzeugen einer Neigebewegung des Lastaufnahmemittels vorgesehen, das in einem Regelkreis in Abhängigkeit von dem Sollwert für die Neigung und der tatsächlichen Neigung gesteuert wird. Bei dieser Anordnung gibt die Bedienperson mit dem Bedienelement den Sollwert für die Neigung vor. In einem Regelkreis wird das Stellglied betätigt, bis die tatsächliche Neigung dem vorgegebenen Sollwert entspricht. Bei dieser Ausgestaltung ist es zweckmäßig, wenn das Bedienelement kein Mittel zum Erzeugen einer Rückstellkraft aufweist. Wenn die Bedienperson die Stellung des Bedienelements nicht verändert, bleibt das Bedienelement in seiner jeweiligen Position, so daß auch der Sollwert für die Neigung unverändert bleibt.According to another embodiment of the invention, when the Control element depending on the pivot angle of the control lever certain target value for the inclination of the load suspension device can be specified. Furthermore, a means for detecting the actual inclination of the Load handling device provided. It is also an actuator for example a hydraulic cylinder, for generating a tilting movement of the Load suspension means provided in a control loop depending on the Setpoint for the slope and the actual slope is controlled. At this Arrangement gives the operator the setpoint for the control element Inclination in front. In a control loop, the actuator is operated until the actual Inclination corresponds to the specified setpoint. With this configuration it is useful if the control element has no means for generating a restoring force having. If the operator does not change the position of the control element, the control element remains in its respective position, so that the setpoint for the slope remains unchanged.
Zusätzliche Funktionen sind mit dem Multifunktionshebel steuerbar, wenn an dem Hebel mindestens ein Schaltelement angeordnet ist, bei dessen Betätigung mittels des Bedienelements anstelle des Neigens der Lastaufnahmevorrichtung eine weitere Funktion des Flurförderzeugs steuerbar ist. Die zusätzlichen Funktionen, beispielsweise ein Lastgreifer oder ein Vorschubgerät, können abhängig von der speziellen Ausführung des Flurförderzeugs definiert werden.Additional functions can be controlled with the multi-function lever when on the Lever at least one switching element is arranged, when actuated by means of the control element instead of tilting the load suspension device Function of the truck is controllable. The additional features for example, a load gripper or a feed device, can depend on the special version of the truck can be defined.
Zweckmäßigerweise ist das Schaltelement nur dann wirksam betätigbar, wenn sich das Bedienelement in einer Neutralstellung befindet. Hierdurch wird sichergestellt, daß durch Betätigen des Schaltelements keine Fehlbedienung der mit dem Bedienelement steuerbaren Funktionen stattfinden kann.The switching element can expediently be actuated effectively only when the control element is in a neutral position. This ensures that by operating the switching element no incorrect operation of the with Control controllable functions can take place.
