Description

Die Erfindung betrifft einen Deichselkopf für ein Flurförderzeug mit Schaltelementen zur Steuerung einer vertikalen Bewegung eines Lastaufnahmemittels sowie der Fahrbewegungen des Flurförderzeugs.The invention relates to a tiller head for a truck with switching elements for controlling a vertical movement of a lifting device and the driving movements of the truck.

Deichselköpfe der genannten Art werden häufig in Mitgänger-Flurförderzeugen oder Fahrerstand-Flurförderzeugen eingesetzt. Während des Betriebs des Flurförderzeugs ergreift die Bedienperson einen an dem Deichselkopf angeordneten Handgriff. Die Schaltelemente sind z.B. als Mikroschalter oder als Folienschalter ausgeführt und im Inneren des Deichselkopfs angeordnet. Zur Betätigung der Schaltelemente weist der Deichselkopf z.B. Drucktasten auf. Die Oberseiten der Drucktasten bilden die Betätigungsflächen für die Schaltelemente. Die Schaltelemente werden betätigt, indem auf die Betätigungsflächen gedrückt wird.Tiller heads of the type mentioned are often used in pedestrian trucks or driver's floor trucks. During operation of the truck, the operator grasps a handle arranged on the tiller head. The switching elements are e.g. designed as a microswitch or as a foil switch and arranged inside the tiller head. For actuating the switching elements, the tiller head comprises e.g. Pushbuttons on. The tops of the push buttons form the actuating surfaces for the switching elements. The switching elements are actuated by pressing on the actuating surfaces.

Aus der EP 0 812 799 A1 ist ein Deichselkopf für ein Flurförderzeug mit Schaltelementen zur Steuerung einer vertikalen Bewegung eines Lastaufnahmemittels sowie der Fahrbewegung des Flurförderzeugs bekannt, bei dem ein Bedienelement ein Steuersignal für eine vertikale Bewegung des Lastaufnahmemittels erzeugt. Insbesondere ist aus der Druckschrift ein Deichselkopf bekannt, bei dem Schaltflächen für die vertikale Bewegung des Lastaufnahmemittels auf einer Oberseite des Deichselkopfs angeordnet sind und ein Drehschalter für die Bedienung der Fahrbewegungen in einer Verlängerung einer Deichsel an dem Deichselkopf angeordnet ist.From the EP 0 812 799 A1 is a tiller head for an industrial truck with switching elements for controlling a vertical movement of a lifting device and the driving movement of the truck is known in which a control element generates a control signal for vertical movement of the lifting device. In particular, from the document a tiller head is known, are arranged in the buttons for the vertical movement of the load receiving means on an upper side of the tiller head and a rotary switch for operating the driving movements in an extension of a drawbar on the tiller head is arranged.

Nachteilig an diesem Stand der Technik ist, dass der Drehschalter aufwändig ist. Die Schaltelemente für die Bedienung der vertikalen Bewegung sind mit an den Griffbereichen des Deichselkopfs angelegten Händen mit den Zeigefingern oder Daumen nur schwer erreichbar, ohne den Griff loszulassen.A disadvantage of this prior art is that the rotary switch is expensive. The switching elements for the operation of the vertical movement are difficult to reach with hands applied to the grip areas of the tiller head with the index fingers or thumb, without letting go of the handle.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Deichselkopf zur Verfügung zu stellen, bei dem auf einfache und kostengünstige Art und Weise Schaltelemente für die Bedienung des Flurförderzeugs griffgünstig angeordnet werden.The invention is therefore an object of the invention to provide a tiller available in which simple and inexpensive way switching elements for the operation of the truck are conveniently located.

Diese Aufgabe wird erfindungsgemäß durch einen Deichselkopf mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a tiller head with the features of claim 1.

Vorteilhaft weist ein Deichselkopf mit Handgriffen für ein Flurförderzeug Schaltelementen zur Steuerung einer vertikalen Bewegung eines Lastaufnahmemittels und zur Steurung eines Antriebsmotors des Flurförderzeugs zur Vorwärts- und/oder Rückwärtsfahrt auf. Ein Schaltelemente für das Heben des Lastaufnahmemittels an einem ersten Handgriff liegt zu einer Innenseite des Deichselkopfs hin. Weiter ist ein Schaltetement für das Senken des Lastaufnahmemittels an einem zweiten Handgriff zu einer Innenseite des Deichselkopfs hin und an einer zu einer Deichsel gegenüberliegenden Stirnseite des Deichselkopfs je zumindest ein Schaltelement für Rückwärtsfahrt und ein Schaltelement für Vorwärtsfahrt angeordnet.Advantageously, a tiller head with handles for a truck switching elements for controlling a vertical movement of a lifting device and for controlling a drive motor of the truck for forward and / or reverse on. A switching elements for lifting the load-carrying means on a first handle is located towards an inner side of the tiller head. Next is a switching element for lowering the load-carrying means on a second handle to an inner side of the tiller head and arranged at an opposite to a drawbar end face of the tiller head depending at least one switching element for reversing and a switching element for forward drive.

Hierdurch ist es möglich, das Flurförderzeug zu steuern, ohne den Handgriff loszulassen. Insbesondere ist die Steuerung des Flurtörderzeugs in ihrem Aufbau kompakt.This makes it possible to control the truck without letting go of the handle. In particular, the control of the truck is compact in its construction.

Besonders vorteilhaft ist es, wenn das Schaltelement für Rückwärtsfahrt und das Schaltelement für Vorwärtsfahrt bei Sicht auf die Stirnseite unmittelbar neben dem rechten Handgriff übereinander angeordnet sind.It is particularly advantageous if the switching element for reversing and the switching element for forward travel when viewed on the front side are arranged next to each other right next to the right hand grip.

Alternativ oder zusätzlich kann ein jeweils zweites Schaltelement für Rückwärtsfahrt und zweites Schaltelement für Vorwärtsfahrt bei Sicht auf die Stirnseite unmittelbar neben dem linken Handgriff übereinander angeordnet sein.Alternatively or additionally, a respective second switching element for reversing and second switching element for forward travel when looking at the front side immediately adjacent to the left handle can be arranged one above the other.

Damit sind diese Schaltelemente besonders gut erreichbar, wenn mit einer Hand der jeweilige Handgriff gehalten wird.Thus, these switching elements are particularly easy to reach when holding the respective handle with one hand.

In vorteilhafter Ausführung bestehen das Schaltelement für Rückwärtsfahrt und das Schaltelement für Vorwärtsfahrt aus Hall-Effekt-Tasten oder Tasten, die einen variablen Widerstand ansteuern. Ebenso können das Schaltelement für das Heben des Lastaufnahmemittels und das Schaltelement für das Senken des Lastaufnahmemittels aus Hall-Effekt-Tasten oder Tasten bestehen, die einen variablen Widerstand ansteuern.In an advantageous embodiment, the switching element for reversing and the switching element for forward drive consist of Hall effect buttons or buttons that drive a variable resistor. Likewise, the switching element for lifting the load receiving means and the switching element for lowering the load receiving means may consist of Hall effect buttons or buttons that drive a variable resistor.

Vorteilhaft sind das Schaltelement für Rückwärtsfahrt und das Schaltelement für Vorwärtsfahrt sowie das Schaltelement für das Heben des Lastaufnahmemittels und das Schaltelement für das Senken des Lastaufnahmemittels wasserdicht ausgeführt.Advantageously, the switching element for reversing and the switching element for forward travel and the switching element for lifting the lifting device and the switching element for lowering the load-carrying means are waterproof.
