Description

Die Erfindung betrifft ein Flurförderzeug gemäß dem Oberbegriff von Anspruch 1, insbesondere Hochregal-Kommissionierstapler, mit einer den Aufenthaltsbereich für eine Bedienungsperson definierenden Standplattform eines Fahrerstandes, wobei an wenigstens einer Seite der Standplattform eine Brüstung vorgesehen ist.The invention relates to an industrial truck according to the preamble of claim 1, in particular high-shelf order picker, with a standing area for an operator defining standing platform of a driver's station, wherein on at least one side of the standing platform a parapet is provided.

Derartige Flurförderzeuge sind aus der US-A-2005/0016782 , der US-A-6,361,003 und der US-A-5,857,747 bekannt.Such trucks are out of the US-A-2005/0016782 , of the US-A-6,361,003 and the US-A-5,857,747 known.

Bei den hier betrachteten Flurförderzeugen kann eine auf der Standplattform stehende Bedienungsperson bei Bedarf über die Brüstung hinweggreifen, etwa um einen Gegenstand aus einem Regal zu nehmen und diesen Gegenstand dann auf eine Palette oder dgl. zu legen, die von Lastaufnahmemitteln des Flurförderzeugs jenseits der Brüstung in Fahrerplatznähe gehalten wird. Die Bedienungsperson erledigt solche Kommissionierarbeitsschritte normalerweise im Stehen und kann sich dabei an der Brüstung abstützen und festhalten. Nach vorn hin ist die Brüstung in dem oberen Bereich häufig als offener Rahmen mit einem oberen horizontalen Querholm ausgebildet, der sich in einer Höhe von ca. 1 m von der Standplattform erstreckt.In the case of the industrial trucks under consideration here, an operator standing on the platform can, if necessary, reach over the parapet, for example, to take an object out of a rack and then place this object on a pallet or the like which is not accessible from the truck's load-carrying means beyond the parapet Driver's seat is kept close. The operator usually performs such picking operations while standing and can support and hold onto the parapet. Towards the front, the parapet in the upper area is often formed as an open frame with an upper horizontal cross member extending at a height of about 1 m from the standing platform.

Es hat sich als nahezu typisches Abstützverhalten gezeigt, dass eine nach vorne zu dem oberen Querholm der Brüstung orientierte und sich daran mit dem Oberkörper oder Bauchbereich abstützende Bedienungsperson zusätzlich mit den Knien an einem unteren Bereich der Brüstung Halt sucht. Es ist bereits vorgeschlagen worden, in dem betreffenden Höhenbereich der Brüstung ein starres Teil des Brüstungsbleches als Kniestütze mit einer dünnen Polsterung auszugestalten. Derartige Knieabstützbleche sind üblicherweise so groß ausgestaltet, dass Bedienungspersonen mit geringer Kniehöhe und Bedienungspersonen mit relativ großer Kniehöhe eine Abstützfläche daran finden können.It has been shown to be almost typical Abstützverhalten that an oriented forward to the upper cross member of the parapet and it is supported with the upper body or abdominal area operator in addition to the knees at a lower portion of the parapet stops. It has already been proposed, in the relevant height range of the parapet, to design a rigid part of the parapet panel as a knee support with a thin padding. Such knee braces are usually designed so large that operators with low knee height and operators with relatively large knee height can find a support surface on it.

Diese relativ großen Knieabstützbleche stellen jedoch eine Sichtbarriere in der Brüstung dar. Eine solche Sichtbehinderung wirkt sich insbesondere dann nachteilig aus, wenn die Bedienungsperson sich nicht unmittelbar an der Brüstung befindet, sondern z. B. auf einem etwas nach hinten verlagerten Sitz, z. B. Klappsitz sitzt und dabei eine Bedienungskonsole bedient, um den Fahrbetrieb und den Lasthandhabungsbetrieb des Flurförderzeugs zu steuern. In einem solchen Fall können die Knieabstützbleche die Sicht der Bedienungsperson auf Komponenten der Lastaufnahmemittel oder auf die Fahrbahn behindern.However, these relatively large knee braces provide a visual barrier in the parapet. Such obstruction in particular affects then disadvantageous if the operator is not directly on the parapet, but z. B. on a slightly rearward seat, z. B. folding seat sits while a control panel operated to control the driving and the load handling operation of the truck. In such a case, the knee pads may interfere with the operator's view of components of the load handler or on the roadway.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Flurförderzeug der eingangs genannten Art bereitzustellen, welches eine Knieabstützmöglichkeit für verschiedene Bedienungspersonen mit unterschiedlichen Kniehöhen im Fahrerstandsbereich bietet, ohne zwangsläufig eine große Sichtbarriere darzustellen.The present invention has for its object to provide an industrial truck of the type mentioned above, which offers a knee support option for different operators with different knee heights in the driver's cab area, without necessarily represent a large visual barrier.

Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.This object is solved by the features of claim 1.

Die Höhenverstellbarkeit des Kniestützelementes erlaubt eine Anpassung an unterschiedliche Kniehöhen verschiedener Bedienungspersonen, wobei das eigentliche Knieabstützelement relativ klein ausgebildet sein kann, so dass es schon aus diesem Grunde keine ausgedehnte Sichtbarriere darstellt. Aufgrund der Höhenverstellbarkeit kann das Kniestützelement in vielen Fällen auch in eine Position verschoben werden, in der es den Blick der Bedienungsperson durch die Brüstung freigibt.The height adjustment of the knee support allows adaptation to different knee heights of different operators, the actual knee support member may be relatively small, so that it is not an extended visual barrier for this reason. Due to the height adjustment, the knee support member can be moved in many cases in a position in which it releases the view of the operator through the parapet.

Das Kniestützelement sollte wenigstens einen gepolsterten Bereich für die Knieabstützung aufweisen, so dass die Bedienungsperson eine relativ weiche und nachgiebige Stützfläche im Kniebereich vorfindet.The knee brace should have at least one padded area for knee support so that the operator will find a relatively soft and resilient support surface in the knee area.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist das Kniestützelement mit einfachen Mitteln auswechselbar an dem Halter angeordnet. Dies schafft die Möglichkeit des einfachen Ersetzens eines abgenutzten Kniestützelementes durch ein neues oder die Möglichkeit der Nutzung der für die lösbare Befestigung des Kniestützelementes am Flurförderzeug vorbereiteten Montageschnittstelle zur Anbringung einer z.B. nur zeitweise zu benutzenden Komponente, wie etwa eines Messgerätes, eines Monitors etc. Hierzu wird vorgeschlagen, dass ein Adapterelement bereitgestellt wird, welches zur lösbaren Verbindung mit der Montageschnittstelle vorbereitet und als Träger für die im Austausch mit dem Kniestützelement zu montierende Komponente geeignet und vorgesehen ist.According to a preferred embodiment of the invention, the knee support element interchangeable with simple means arranged on the holder. This provides the possibility of simply replacing a worn knee brace by a new or the possibility of using the prepared for the releasable attachment of the knee brace on the truck mounting interface for mounting a example only temporarily used component, such as a meter, a monitor, etc. This is proposed that an adapter element is provided which is prepared for releasable connection to the mounting interface and is suitable and provided as a support for the component to be mounted in exchange with the knee support element.

Gemäß der Erfindung weisen das Kniestützelement und der Halter einander komplementäre Steckverbindungselemente auf, die zu einer Steckverbindung zusammengefügt sind. Dabei kann das Kniestützelement z. B. zwei Einsteckstangen als Steckverbindungselemente aufweisen und der Halter mit Einstecklöchern zur Aufnahme der Einsteckstangen versehen sein. Als technisch einfache und zuverlässig funktionierende Lösung dieser Art hat sich ein Steckverbindungsmechanismus erwiesen, wie er auch bei der Halterung von Kopfstützen auf Kfz-Sitzlehnen verwendet wird. Ein solcher Steckmechanismus ermöglicht das bedarfsweise Entfernen des Kniestützelementes durch Herausziehen der daran vorgesehenen Einsteckstangen aus den halterseitigen Einstecklöchern, ggf. nach Lösen einer Einrastverriegelung zwischen dem Halter und den Einsteckstangen. Ein solcher Steckmechanismus ermöglicht ferner eine rasche und einfache Höhenverstellung des Kniestützelementes. Je nach konkreter Ausführungsform des Steckmechanismus kann das Kniestützelement in verschiedenen diskreten Raststellungn fixierbar - oder kontinuierlich höhenverstellbar sein. Dies gilt auch für Ausführungsformen von Verbindungsmechanismen zwischen Kniestützelement und Halter, welche nicht als Steckverbindungen ausgestaltet sind.According to the invention, the knee support member and the holder on each other complementary plug connection elements which are joined together to form a plug connection. In this case, the knee support z. B. have two plug-in rods as plug-in connection elements and the holder be provided with insertion holes for receiving the Einsteckstangen. As a technically simple and reliable solution of this kind, a plug connection mechanism has proven, as it is also used in the mounting of headrests on car seat backrests. Such a plug-in mechanism allows the need for removal of the knee support element by pulling out the provided thereon Einsteckstangen from the holder-side insertion holes, possibly after releasing a latching between the holder and the Einsteckstangen. Such a plug-in mechanism also allows a quick and easy height adjustment of the knee support element. Depending on the specific embodiment of the plug-in mechanism, the knee support element can be fixed in various discrete locking positions - or be continuously height-adjustable. This also applies to embodiments of connection mechanisms between knee support element and holder, which are not configured as plug-in connections.

Gemäß einer Weiterbildung der Erfindung hat das Kniestützelement zwei unter einem Winkel kleiner als 180°, vorzugsweise kleiner als 120°, voneinander abstehende Hauptabschnitte, von denen einer mit einer Außenseite nach oben orientiert ist und an seiner dieser Außenseite entgegengesetzten Unterseite Einsteckstangen als Steckverbindungselemente aufweist, wobei der andere Hauptabschnitt dem Aufenthaltsbereich für die Bedienungsperson zugewandt ist und eine Polsterung aufweist. Vorzugsweise liegt der Winkel, den die Hauptabschnitte miteinander einschließen, bei etwa 90°, wobei zweckmäßigerweise beide Hauptabschnitte eine Polsterung aufweisen. Die Bedienungsperson kann bei einem solchen Kniestützelement das Knie wahlweise nach vorn gegen den dem Aufenthaltsbereich zugewandten Hauptabschnitt abstützen oder auf dem oberen Hauptabschnitt auflegen. Ferner bietet die abgewinkelte Ausgestaltung des Kniestützelementes die Möglichkeit des Überdeckens kantiger und harter Brüstungselemente im betreffenden Bereich der Brüstung. Gemäß einer Variante der vorstehend angesprochenen Ausführungsform des Kniestützelementes hat der obere Hauptabschnitt an seiner nach oben orientierten Außenseite eine Mulde als Ablagefach für Schreibutensilien oder dgl.According to one embodiment of the invention, the knee support element has two at an angle less than 180 °, preferably less than 120 °, from each other projecting main sections, one of which is oriented with an outer side upwards and has on its outer side opposite underside insertion rods as plug-in connection elements, wherein the other main section faces the occupied area for the operator and has a padding. Preferably, the angle which the main sections enclose with each other, is about 90 °, expediently both main sections have a padding. The operator can support the knee in such a knee support selectively forward against the main area facing the main portion or hang up on the upper main section. Furthermore, the angled design of the knee support element offers the possibility of covering edgy and hard parapet elements in the relevant area of the parapet. According to a variant of the above-mentioned embodiment of the knee support member, the upper main portion has on its upwardly oriented outside a trough as a storage compartment for writing utensils or the like.

Üblicherweise haben die Flurförderzeuge der hier betrachteten Art eine Bedienungskonsole am Fahrerstand, die von dem Aufenthaltsbereich der Bedienungsperson erreichbar nahe der Brüstung angeordnet ist. Zweckmäßigerweise ist wenigstens ein höhenverstellbares Kniestützelement nach der Erfindung seitlich versetzt zur Bedienungskonsole im Brüstungsbereich vorgesehen.Usually, the trucks of the type considered here have a control panel on the driver's station, which is arranged accessible from the area of residence of the operator near the parapet. Conveniently, at least one height-adjustable knee support member according to the invention is provided laterally offset from the control console in the parapet area.

In Fig. 2a sind die Kniestützelemente 26 in ihrer niedrigsten Stellung gezeichnet, wohingegen sie in Fig. 2b in einer angehobenen Einstellung für größere Kniehöhen dargestellt sind.In Fig. 2a the knee support members 26 are drawn in their lowest position, whereas in Fig. 2b are shown in a raised setting for greater knee heights.

Fig. 3a zeigt ein Kniestützelement 26 in der Stellung gemäß Fig. 2a, und zwar aus der Perspektive, die in Fig. 2a mit dem Pfeil IIIa angedeutet ist. Der Brüstungsblechkasten 28 ist in Fig. 3a der Einfachheit halber ausgebrochen dargestellt. Fig. 3a shows a knee support member 26 in the position according to Fig. 2a , from the perspective of, in Fig. 2a indicated by the arrow IIIa. The parapet case 28 is in Fig. 3a for the sake of simplicity broken out.

Fig. 3b zeigt das Kniestützelement 26 in der herausgezogenen Stellung gemäß Fig. 2b aus der vorderen Perspektive, wie sie in Fig. 2b mit dem Pfeil IIIb angedeutet ist. Fig. 3b shows the knee support member 26 in the pulled-out position according to Fig. 2b from the front perspective, as in Fig. 2b indicated by the arrow IIIb.

Der Brüstungsblechkasten 28 und das Kniestützelement 26 weisen einander komplementäre Steckverbindungselemente auf. Am Kniestützelement 26 sind als Steckverbindungselemente die in Fig. 3b gut erkennbaren Einsteckstangen 30 vorgesehen, die in Einstecklöchern 32 an der Oberseite des Brüstungsblechkastens 28 eingesteckt sind. Die Einstecklöcher 32 sind Teil von Steckaufnahmen, wie sie von Kopfstützbefestigungen in Sitzlehnen von Kfz-Sitzen her bekannt sind. Entsprechend ähnlich sind auch die Einsteckstangen 30 den von Kopfstützen her bekannten Einsteckstangen.The parapet case 28 and the knee support member 26 have complementary plug connection elements. At the knee support member 26 are as plug connection elements in Fig. 3b well recognizable Einsteckstangen 30 provided, which are inserted into insertion holes 32 at the top of the parapet plate box 28. The insertion holes 32 are part of plug-in receptacles, as they are known from Kopfstützbefestigungen in seat backs of motor vehicle seats ago. Similarly, the Einsteckstangen 30 are known from head restraints ago plug-in rods.

Die Kniestützelemente 26 können je nach Bedarf mit ihren Einsteckstangen 30 mehr oder weniger weit in die Einstecklöcher 32 hineingesteckt werden, um eine gewünschte Höheneinstellung vorzunehmen. Rastmechanismen, zu denen die in Fig. 3b erkennbaren Rastkerben 34 gehören, erlauben Höheneinstellungen in diskreten Stufen.The knee bracing 26 may be more or less inserted into the insertion holes 32 as required with their Einsteckstangen 30 to make a desired height adjustment. Locking mechanisms, to which the in Fig. 3b recognizable notches 34 allow height adjustments in discrete stages.

Aus den Figuren 3a und 3b ist ferner gut zu erkennen, dass die Kniestützelemente 26 zwei unter einem Winkel 38 von etwa 90° voneinander abstehende Hauptabschnitte 40, 42 aufweisen, welche vorzugsweise beide gepolstert sind. Der obere Hauptabschnitt 40 ist mit seiner Außenseite 44 nach oben orientiert und weist an seiner Unterseite 46 die Einsteckstangen 30 auf. Der andere Hauptabschnitt 42 ist dem Fahrerstand bzw. dem Aufenthaltsbereich für die Bedienungsperson zugewandt. Eine solche Winkelform des Kniestützelements 26 hat den Vorteil, dass es harte und scharfkantige Brüstungselemente, wie etwa den oberen Bereich des Brüstungsblechkastens 28 bereichsweise überdeckt, und somit einen komfortablen Schutz für die Bedienungsperson gegen unbeabsichtigtes Anstoßen an dem Brüstungsblechkasten 28 oder dgl. bietet (vgl. insbesondere Fig. 2a und Fig. 3a).From the FIGS. 3a and 3b It can also be clearly seen that the knee support elements 26 have two main sections 40, 42 projecting at an angle 38 of approximately 90 ° from one another, which are preferably both upholstered. The upper main section 40 is oriented with its outer side 44 upwards and has on its underside 46 on the Einsteckstangen 30 on. The other main section 42 faces the driver's station or the occupied area for the operator. Such an angular shape of the knee support member 26 has the advantage that it covers hard and sharp-edged parapet elements, such as the upper portion of the parapet panel 28 partially, and thus provides a comfortable protection for the operator against accidental bumping on the parapet case 28 or the like (see. especially Fig. 2a and Fig. 3a ).

Diese Winkelform der Kniestützelemente bietet der Bedienungsperson ferner die Möglichkeit, ihr Knie oben auf dem Abschnitt 44 aufzulegen (teils knieende Haltung) oder das Knie gegen das Hauptabschnitt 42 nach vorne hin abzustützen (stehende Haltung).This angle shape of the knee bracing elements also offers the operator the ability to put her knee on top of the section 44 (partly kneeling posture) or to support the knee against the main section 42 to the front (standing posture).

Aufgrund der Höhenverstellbarkeit der Kniestützelemente können diese rasch an unterschiedliche Kniehöhen angepasst werden. Sie können relativ klein ausgebildet sein, so dass sie der Bedienungsperson möglichst wenig Sicht in dem Fensterbereich 48 des vorderen Brüstungsrahmens (vgl. Fig. 2a, Fig. 2b) versperren. Die Frage der Sichtbehinderung hat insbesondere Bedeutung, wenn die Bedienungsperson das Flurförderzeug in Sitzhaltung auf einem Fahrersitz 50 steuert, der ausklappbar im hinteren Bereich des Fahrerstandes 2 vorgesehen ist. Die Bedienungsperson kann sich dabei nahezu optimale Sichtbedingungen verschaffen, wenn sie das relativ kleine Kniestützelement 26 in die unterste Position gemäß Fig. 2a verschiebt.Due to the height adjustment of the knee bracing elements they can be adapted quickly to different knee heights. They can be made relatively small so that they give the operator as little visibility in the window area 48 of the front parapet frame (see. Fig. 2a, Fig. 2b ) block. The question of visual obstruction is of particular importance when the operator controls the truck in a sitting position on a driver's seat 50 which is provided in the rear area of the driver's seat 2 so that it can be folded out. The operator can thereby obtain almost optimal viewing conditions, when the relatively small knee brace 26 in the lowest position according to Fig. 2a shifts.

Eine Abwandlung des vorstehend erläuterten Ausführungsbeispiels könnte darin bestehen, die Kniestützelemente 26 auch seitlich, also horizontal verstellbar oder ggf. verschwenkbar anzuordnen.A modification of the above-described embodiment could consist in the knee support elements 26 also laterally, so horizontally adjustable or possibly to arrange pivoting.

Fig. 4 zeigt ein Kniestützelement 26, das als Besonderheit gegenüber dem Kniestützelement 26 aus Fig. 3a an der nach oben orientierten Außenseite 44 des Hauptabschnitts 40 eine Mulde 52 als Ablagefach für Schreibutensilien oder dgl. hat. Fig. 4 shows a knee support member 26, the special feature over the knee support member 26 from Fig. 3a on the upwardly oriented outer side 44 of the main portion 40 has a trough 52 as a storage compartment for writing utensils or the like ..
