Description

Die Erfindung bezieht sich auf eine Anzeigeanordnung an einem Hochhubflurförderzeug nach dem Patentanspruch 1.The invention relates to a display arrangement on a high-lift truck according to claim 1.

Hochhubflurförderzeuge sind entweder Mitfahrer- oder Mitgehflurförderzeuge. Bei letzteren erfolgt ihre Betätigung mit Hilfe einer Deichsel, welche daß angetriebene Rad zu Lenkzwecken verschwenkt. An dem Deichselkopf sind außerdem die Bedienelemente für den Einsatz des Flurförderzeugs angebracht, insbesondere zur Steuerung des Fahrantriebs und der Hubvorrichtung. Anzeigeelemente, etwa für den Ladezustand der Batterie, die Hubhöhe und andere Daten sind in der Haube des Antriebsteils integriert.High-lift trucks are either passenger or co-haul trucks. In the latter, their operation takes place with the help of a drawbar, which pivots the driven wheel for steering purposes. At the tiller head also the controls for the use of the truck are mounted, in particular for controlling the traction drive and the lifting device. Display elements, for example for the state of charge of the battery, the lifting height and other data are integrated in the hood of the drive part.

Bei Mitfahrgeräten hat der Fahrer die Anzeigen relativ gut im Blick. Anders verhält es sich bei den Mitgehfahrzeugen, da die Höhe des Antriebsteils relativ niedrig ist und der Bediener nach unten sehen muss, um den Anzeigestand zu verfolgen.For riders, the driver has the displays relatively well in view. The situation is different with the Mitgehfahrzeugen because the height of the drive part is relatively low and the operator has to look down to track the display

Der Erfindung liegt daher die Aufgabe zugrunde, eine Anzeigeanordnung für ein Hochhubflurförderzeug, insbesondere ein Mitgehfahrzeug, zu schaffen, die vom Bediener relativ einfach ablesbar ist, ohne dass sie einen hohen Fertigungs- und Montageaufwand erfordert.The invention is therefore based on the object to provide a display arrangement for a high-lift truck, in particular a Mitgehfahrzeug, which is relatively easy to read by the operator, without requiring a high manufacturing and assembly costs.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is solved by the features of patent claim 1.

Die Erfindung geht von der Tatsache aus, daß aus Sicherheitsgründen in vielen Fällen eine Schutzscheibe am Hubgerüst angebracht ist. Die Schutzscheibe muss naturgemäß durchsichtig sein, ist aber geeignet, den Bediener vor Gefahren, die vom Lastteil her drohen, insbesondere bei angehobener Last, zu schützen. Erfindungsgemäß ist ein flaches Anzeigeelement an der Schutzscheibe angebracht. Die erforderlichen Signalleitungen werden nach unten zum Steuerteil des Flurförderzeugs geführt. Das Anzeigeelement kann beispielsweise den Ladezustand der Batterie anzeigen, die Hubhöhe, das Lastgewicht oder dergleichen. Vorzugsweise ist das flache Anzeigeelement seitlich an der Signalscheibe angebracht, um den Durchblick so wenig wie möglich zu beeinträchtigen. Vorzugsweise ist das Anzeigeelement in Sichthöhe angebracht, so daß es stets vom Bediener des Fahrzeugs beobachtet werden kann.The invention is based on the fact that for safety reasons, in many cases, a protective screen is mounted on the mast. The protective screen must of course be transparent, but is suitable to protect the operator from hazards threatening from the load part, in particular when the load is raised. According to the invention, a flat display element is attached to the protective pane. The required signal lines are led down to the control section of the truck. The display element may indicate, for example, the state of charge of the battery, the lifting height, the load weight or the like. Preferably, the flat display element is mounted laterally on the signal disk in order to impair the view as little as possible. Preferably, the display element is mounted at eye level, so that it can always be observed by the operator of the vehicle.

Das Anzeigeelement kann z.B. an der Schutzscheibe aufgeklebt sein. Dies gilt auch für flache Signalkabel. Alternativ kann das Anzeigeelement im Siebdruckverfahren auf die Schutzscheibe aufgebracht sein. Dies gilt auch für Signalleitungen. Schließlich kann das Anzeigeelement in der Schutzscheibe eingebaut, z.B. zwischen zwei Schichten angeordnet sein.The display element may, for example, be glued to the protective pane. This also applies to flat signal cables. Alternatively, the display element may be screen printed on the protective screen. This also applies to signal lines. Finally, the display element can be installed in the protective pane, for example arranged between two layers.

Das Anzeigeelement kann z.B. ein Foliendisplay oder ein Display in Papierform sein, welche als Anzeigeelemente an sich bekannt sind. Es versteht sich, daß das Anzeigeelement unterschiedliche Zustände oder Betriebsdaten des Flurförderzeugs anzeigen kann. Dabei können unterschiedliche Zustände oder Betriebsdaten von einem einzigen Anzeigeelement angezeigt werden oder alternativ von zwei oder mehr Anzeigeelementen in Form flacher Displays auf oder in der Schutzscheibe. Die Schutzscheibe kann aus einem durchsichtigen Kunststoff oder aus Glas bestehen.The display element may e.g. a foil display or a display in paper form, which are known as display elements per se. It is understood that the display element can display different states or operating data of the truck. In this case, different states or operating data can be displayed by a single display element or alternatively by two or more display elements in the form of flat displays on or in the protective pane. The protective screen may consist of a transparent plastic or glass.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand einer Zeichnung näher erläutert.An embodiment of the invention will be explained in more detail with reference to a drawing.

Die einzige Figur zeigt teilweise perspektivisch die Rückansicht eines Hochhubflurförderzeuges mit einer Anzeigeanordnung nach der Erfindung.The single figure shows a partially perspective view of the rear view of a high-lift truck with a display device according to the invention.

In der Figur ist ein deichselgelenktes Hochhubflurförderzeug zu erkennen mit einem Antriebsteil 10 und einem Lastteil, von dem ein Hubgerüst 12 angedeutet ist. Im Antriebsteil 10 befinden sich u. a. ein Fahrmotor und eine Hubvorrichtung für eine an dem Hubgerüst 12 geführte, nicht gezeigte Lastgabel. Die Lenkung und Steuerung des Betriebes des Flurförderzeugs erfolgt mit Hilfe einer Deichsel 14, an deren Deichselkopf 16 Bedienelemente (nicht gezeigt) angebracht sind. Mit Hilfe der Deichsel lässt sich das nicht gezeigte Antriebsrad verschwenken. Fahrschalter am Deichselkopf 16 dienen zur Steuerung des nicht gezeigten Fahrmotors. Die beschriebenen aber nicht gezeigten Einzelheiten sind allgemein bekannt und sollen daher nicht weiter erörtert werden.In the figure, a drawbar-steered high-lift truck can be seen with a drive part 10 and a load part, of which a mast 12 is indicated. In the drive part 10 are u. a. a traction motor and a lifting device for a guided on the mast 12, not shown fork. The steering and control of the operation of the truck is done with the help of a drawbar 14, at the tiller head 16 controls (not shown) are mounted. With the help of the drawbar, the drive wheel, not shown, can be pivoted. Travel switches on the tiller head 16 serve to control the travel motor, not shown. The details described but not shown are well known and therefore will not be discussed further.

An dem Hubgerüst 12 ist eine Schutzscheibe 18 aus Glas angebracht. Sie dient dem Schutz des Bedieners, erlaubt jedoch den Durchblick zur Vorderseite des Flurförderzeugs. Auf die Schutzscheibe 18 ist ein Foliendisplay 20 aufgeklebt. Es enthält z.B. eine Anzeige für den Ladezustand der Batterie für das Flurförderzeug.On the mast 12, a protective glass 18 is attached. It serves to protect the operator, but allows the view to the front of the truck. On the protective plate 18, a film display 20 is glued. It contains, for example, an indication of the state of charge of the battery for the truck.

Das Foliendisplay 20 ist annähernd in Sichthöhe angebracht, und zwar seitlich an der Schutzscheibe 18 nahe einer Stütze des Hubgerüsts 12. Flachkabel 22 für das Foliendisplay 20 sind ebenfalls an der Schutzscheibe 18 aufgeklebt und in das Innere des Antriebsteils 10 hineingeführt zu einem nicht gezeigten Steuerteil für das Flurförderzeug. Wie erkennbar, befindet sich das Foliendisplay 20 auf der dem Antriebsteil 10 zugekehrten Seite der Schutzscheibe 18. Es kann jedoch auch auf der entgegengesetzten Seite aufgeklebt oder in die Schutzscheibe integriert sein. Alternativ können Display und Leitungen auch im Siebdruckverfahren auf die Schutzscheibe 18 aufgebracht werden.The film display 20 is mounted approximately at eye level, namely the side of the protective plate 18 near a support of the mast 12. Flat cable 22 for the film display 20 are also glued to the protective plate 18 and guided into the interior of the drive member 10 to a control part, not shown the truck. As can be seen, the film display 20 is located on the drive part 10 facing side of the protective screen 18. However, it may also be glued on the opposite side or integrated into the protective screen. Alternatively, the display and lines can also be applied to the protective screen 18 by screen printing.
