Description

Die Erfindung betrifft ein Flurförderzeug, insbesondere Gegengewichtsgabelstapler, mit einem einen Fahrersitz und eine Bodenplattform umfassenden Fahrerarbeitsplatz, der an zwei aneinander angrenzenden Seiten von einer wandartigen Seitenbegrenzung begrenzt ist.The invention relates to an industrial truck, in particular counterbalance forklift truck, with a driver's workplace comprising a driver's seat and a ground platform, which is bounded on two mutually adjacent sides by a wall-like lateral boundary.

Bei Flurförderzeugen erfolgt in der Regel eine Bedienung, in dem sich eine Bedienperson innerhalb des Fahrerarbeitsplatzes in einer dem Lastteil zugewandten Bedienposition befindet. In einer derartigen Bedienposition kann eine mit dem Lastteil aufgenommene Last die Sicht der Bedienperson einschränken. Eine solche Vorrichtung ist in Dokument US 2007/0096531 A1 offenbart.For industrial trucks usually takes place an operation in which an operator is located within the driver's workplace in a load part facing the operating position. In such an operating position, a load taken with the load part can restrict the operator's view. Such a device is in document US 2007/0096531 A1 disclosed.

Um eine ergonomisch günstige Fahrt sowohl in Vorwärtsfahrt, d.h. einer Fahrt in Richtung des Lastteils mit dem Lastteil in Fahrtrichtung vorne, als auch in Rückwärtsfahrt, d.h. einer Fahrt in entgegengesetzter Richtung mit dem Lastteil in Fahrtrichtung hinten, zu ermöglichen, ist es bereits bekannt, den Fahrersitz um eine vertikale Schwenkachse zwischen verschiedenen Bedienpositionen verschenkbar im Fahrerarbeitslatz anzuordnen. Ein Flurförderzeug mit einem um eine vertikale Achse um 180° verschwenkbaren Fahrersitz ist aus der DE 30 42 956 A1 bekannt. Bei derartigen, verschwenkbaren Fahrersitzen ist nachteilig, dass im Bereich einer Bodenplattform des Fahrerarbeitsplatzes eine Schwenkkonsole oder eine Drehteller zum Verschwenken des Fahrersitzes erforderlich ist, so dass ein Betrieb des Flurförderzeugs in einer stehenden Bedienstellung, bei der die Bedienperson auf der Bodenplattplattform steht, zu einer ungünstigen Ergonomie führt.In order to enable an ergonomically favorable ride both in forward travel, ie a drive in the direction of the load part with the load part in the front direction, as well as in reverse, ie a ride in the opposite direction with the load part in the direction of travel behind, it is already known Driver's seat to arrange a vertical pivot axis between different operating positions verschenkbar in the driver's workstation. An industrial truck with a pivotable about a vertical axis by 180 ° driver's seat is from the DE 30 42 956 A1 known. In such, pivotable driver's seats is disadvantageous that in the area of a floor platform of the driver's workplace, a swivel bracket or a turntable for pivoting the driver's seat is required, so that operation of the truck in a standing operating position, in which the operator is on the platform platform, to an unfavorable Ergonomics leads.

Aus der DE 100 13 082 A1 ist ein Flurförderzeug mit einer drehbaren Fahrerkabine bekannt, die um eine vertikale Achse um 180° verschwenkbar angeordnet ist, um eine verbesserte Sicht für eine in der Fahrerkabine befindliche Bedienperson bei Vorwärtsfahrt und Rückwärtsfahrt zu ermöglichen. Eine verschwenkbare Fahrerkabine weist jedoch einen hohen Bauaufwand auf.From the DE 100 13 082 A1 a truck with a rotating cab is known, which is arranged pivotable about a vertical axis by 180 ° in order to allow improved visibility for an operator located in the driver's cab when driving forwards and backwards. However, a pivotable cab has a high construction cost.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Flurförderzeug der eingangs genannten Gattung zur Verfügung zu stellen, bei dem durch Verstellen des Fahrersitzes eine ergonomisch günstige Vorwärtsfahrt und Rückwärtsfahrt ermöglicht wird und eine stehende Bedienstellung für eine Bedienperson mit günstiger Ergonomie erzielt wird.The present invention has for its object to provide an industrial truck of the type mentioned, in which by adjusting the driver's seat ergonomically favorable forward drive and reverse travel is possible and a standing operating position for an operator is achieved with favorable ergonomics.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Fahrersitz an der wandartigen Seitenbegrenzung des Fahrerarbeitsplatzes zwischen verschiedenen Bedienpositionen, in denen der Fahrersitz bezüglich einer vertikalen Achse unterschiedlich orientiert ist, verstellbar angeordnet ist. Erfindungsgemäß ist der Fahrersitz an der wandartigen Seitenbegrenzung des Fahrerarbeitsplatzes verstellbar angeordnet, um den Fahrersitz zwischen verschiedenen Bedienpositionen zu verschwenken. Durch eine verstellbare Anbringung des Fahrersitzes an einer wandartigen Seitenbegrenzung des Fahrerarbeitsplatzes kann gegenüber einer schwenkbaren Anordnung des Fahrersitzes an der Bodenplattform erzielt werden, dass keine Schwenkkonsolen oder Drehteller zum Verschwenken des Fahrersitzes an der Bodenplattform erforderlich sind, so dass eine durchgehende und geschlossenen Bodenplattform ohne störende Hindernisse erzielt wird. Eine derartige Bodenplattform ermöglicht eine ergonomisch günstige stehende Bedienstellung für die Bedienperson, so dass mit der erfindungsgemäßen Verstellung und Variabilität des Fahrersitzes entlang einer Seitenbegrenzung des Fahrerarbeitsplatzes unterschiedliche Bedienposition des Fahrersitzes ermöglicht werden, in denen durch die hindernisfreie Bodenplattform sowohl eine sitzende Bedienstellung als auch eine stehende Bedienstellung bei günstiger Ergonomie ermöglicht wird. Mit der erfindungsgemäßen Verstellung des Fahrersitzes entlang einer Seitenbegrenzung des Fahrerarbeitsplatzes wird somit ein ergonomisch günstiger Fahrerarbeitsplatz erzielt, der eine ergonomische Bedienung des Flurförderzeugs in Vorwärtsfahrt und in Rückwärtsfahrt sowohl in stehender Bedienstellung als auch in sitzender Bedienstellung ermöglicht.This object is achieved in that the driver's seat on the wall-like side boundary of the driver's workplace between different operating positions in which the driver's seat is oriented differently with respect to a vertical axis, is adjustably arranged. According to the driver's seat is adjustably arranged on the wall-like side boundary of the driver's workplace to pivot the driver's seat between different operating positions. By an adjustable attachment of the driver's seat to a wall-like side boundary of the driver's workplace can be achieved with respect to a pivotable arrangement of the driver's seat on the ground platform that no swivel brackets or turntable for pivoting the driver's seat on the ground platform are required, so that a continuous and closed ground platform without disturbing obstacles is achieved. Such a floor platform allows an ergonomically favorable standing operating position for the operator, so that with the inventive adjustment and variability of the driver's seat along a side boundary of the driver's workplace different operating position of the driver's seat are made possible in which by the obstacle-free ground platform both a seated operating position and a standing operating position is made possible with favorable ergonomics. With the inventive adjustment of the driver's seat along a side boundary of the driver's workplace thus an ergonomically favorable driver's workplace is achieved, which allows ergonomic operation of the truck in forward drive and reverse in both standing operating position and in sitting operating position.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist der Fahrersitz in Umfangsrichtung der Seitenbegrenzung an der Seitenbegrenzung verschiebbar angeordnet. Mit einer verschiebbaren Anordnung des Fahrersitzes an der wandartigen Seitenbegrenzung des Fahrerarbeitsplatzes kann ein Verschwenken des Fahrersitzes um eine imaginäre vertikale Schwenkachse innerhalb des Fahrerarbeitsplatzes mit geringem Bauaufwand erzielt werden.According to a preferred embodiment of the invention, the driver's seat is arranged displaceably in the circumferential direction of the side boundary on the side boundary. With a displaceable arrangement of the driver's seat on the wall-like side boundary of the driver's workplace, a pivoting of the driver's seat about an imaginary vertical pivot axis within the driver's workplace can be achieved with low construction costs.

Der Fahrersitz ist somit zwischen einer Bedienposition für eine Vorwärtsfahrt, in der der Fahrersitz dem Lastteil zugewandt ist und somit eine an oder auf dem Fahrersitz befindliche Bedienperson in Längsrichtung des Flurförderzeugs in Richtung des Lastteils blickt, und einer quer ausgerichteten Bedienposition, in der eine an oder auf dem Fahrersitz befindliche Bedienperson in Querrichtung des Flurförderzeugs blickt, um im Wesentlichen 90° verstellbar an der wandartigen Seitenbegrenzung angeordnet. In der quer ausgerichteten Bedienposition kann die Bedienposition durch leichtes Drehen des Kopfes eine ergonomisch günstige Haltung für eine Rückwärtsfahrt mit in Fahrtrichtung hinten liegendem Lastteil einnehmen.The driver's seat is arranged adjustable according to a possible embodiment of the invention between a load part facing the operating position and a transversely oriented operating position. The driver's seat is thus between an operating position for a forward drive, in which the driver's seat faces the load part and thus an operator located on or on the driver's seat in the longitudinal direction of the truck in the direction of the load part, and a transversely oriented operating position in which a on or Operator located in the driver's seat in the transverse direction of the truck, arranged to be substantially 90 ° adjustable on the wall-like side boundary. In the transversely oriented operating position, the operating position by slightly turning the head can take an ergonomic position for a reverse drive with lying in the direction of travel back load part.

Besondere Vorteile ergeben sich, wenn der Fahrersitz gemäß einer bevorzugten Ausgestaltungsform der Erfindung zwischen einer dem Lastteil zugewandten Bedienposition und einer dem Lastteil abgewandten Bedienposition verstellbar angeordnet ist. Der Fahrersitz ist somit zwischen einer Bedienposition für eine Vorwärtsfahrt, in der der Fahrersitz dem Lastteil zugewandt ist und somit eine an oder auf dem Fahrersitz befindliche Bedienperson in Längsrichtung des Flurförderzeugs in Richtung des Lastteils blickt, und einer gegenüberliegenden Bedienposition für eine Rückwärtsfahrt, in der der Fahrersitz dem Lastteil abgewandt ist und somit eine an oder auf dem Fahrersitz befindliche Bedienperson in Längsrichtung des Flurförderzeugs in eine dem Lastteil entgegengesetzte Richtung blickt und den Lastteil im Rücken hat, um im Wesentlichen 180° verstellbar an der Seitenbegrenzung angeordnet. Der Fahrersitz kann somit durch Verschieben entlang der Seitenbegrenzung in einfacher und schneller Weise zwischen einer Vorwärtsfahrtstellung und einer Rückwärtsfahrtstellung verstellt werden.Particular advantages arise when the driver's seat is arranged adjustable according to a preferred embodiment of the invention between a load part facing the operating position and a load part remote from the operating position. The driver's seat is thus between an operating position for a forward drive, in which the driver's seat faces the load part and thus an operator located on or on the driver's seat in the longitudinal direction of the truck in the direction of the load part, and an opposite operating position for a reverse drive, in which Driver's seat facing away from the load part and thus an operator located on or on the driver's seat in the longitudinal direction of the truck in a direction opposite to the load part and the load part in the back, arranged to be substantially 180 ° adjustable on the side boundary.
