Description

Die Erfindung betrifft eine Palette nach dem Oberbegriff des Anspruchs 1.The invention relates to a pallet according to the preamble of claim 1.

Derartige Paletten sind aus der Praxis bekannt. Die Naht zwischen Ober- und Unterteil verläuft in Höhe des Decks oder unmittelbar darunter, also jedenfalls im obersten Bereich der Palette. In der Praxis ergibt sich die Problematik, dass bei der Handhabung der Palette mit Hilfe von Flurförderfahrzeugen die Gabeln bzw. deren einzelne Zinken möglicherweise nicht korrekt zu den Einfahröffnungen der Palette ausgerichtet sind, so dass die Gefahr besteht, dass die Zinken gegen die Naht der mehrteiligen Palette gestoßen werden können. In diesem Bereich ist die Palette jedoch vergleichsweise empfindlich, so dass bei derartigen Kontakten unerwünscht große Beschädigungen der Palette resultieren können.Such pallets are known in practice. The seam between the upper and lower part runs at the level of the deck or immediately below it, ie at least in the uppermost area of the pallet. In practice, there is the problem that when handling the pallet using industrial trucks, the forks or their individual prongs may not be aligned correctly with the entry openings of the pallet, so that there is a risk that the tines against the seam of the multipart Pallet can be encountered. In this area, however, the range is relatively sensitive, so that in such contacts undesirably large damage to the pallet can result.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Palette dahingehend zu verbessern, dass diese möglichst preisgünstig herstellbar und dabei möglichst stabil und gegen Beschädigungen durch die Zinken eines Flurförderfahrzeugs möglichst gut geschützt ist.The invention has for its object to improve a generic range to the effect that this is possible inexpensively produced and thereby as stable as possible and protected against damage by the tines of a material handling vehicle as well as possible.

Diese Aufgabe wird durch eine Palette mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a pallet having the features of claim 1.

Die Erfindung schlägt mit anderen Worten vor, die Naht zwischen Ober- und Unterteil am äußeren Umfang der Palette in die untere Hälfte der Palette zu verlegen, wobei die Naht möglichst vorteilhaft möglichst bodennah verläuft. Die Erfindung geht dabei von der Überlegung aus, dass die Gabel eines Flurförderfahrzeuges nur in den seltensten Fällen zu tief angesetzt werden wird, weil in derartigen Fällen die Gabel über den Untergrund schleift auf dem die Palette aufsteht, so dass diese zu tiefe Einstellung dem Fahrzeugführer des Flurförderfahrzeuges sofort bewusst wird und er diese zu tiefe Einstellung der Gabel korrigiert. Aber auch bei Paletten, die nicht auf dem Untergrund aufstehen, sondern beispielsweise auf eine andere Palette aufgestapelt sind, ist der bodennahe, untere Bereich der Palette nahe den Kufen deutlich stabiler als der Bereich des oberen Decks: Allein schon dadurch, dass die von der Seitenfläche der Palette zugängliche Nahtlinie auf den Bereich der Füße beschränkt ist, durch welche die Naht verläuft, ergibt sich eine drastisch kürzere Nahtlinie als bei Paletten, bei denen die Nahtlinie zirkumferent um den gesamten Umfang des Decks herum an die Außenseite der Palette mündet, so dass aufgrund dieser kürzeren Nahtlänge entsprechend die prozentuale Wahrscheinlichkeit verringert ist, dass überhaupt ein Stoß gegen die Nahtlinie erfolgen kann.In other words, the invention proposes to lay the seam between the upper and lower part on the outer circumference of the pallet in the lower half of the pallet, wherein the seam extends as advantageously as possible as close to the ground as possible. The invention is based on the consideration that the fork of a material handling vehicle will only be set too low in the rarest cases, because in such cases, the fork over the ground grinds on which the pallet gets up, so that this setting too low the driver of the Immediately becomes aware of industrial truck and he corrects this too low adjustment of the fork. But even with pallets that do not stand up on the ground, but are stacked, for example, on another pallet, the ground near, lower range of the range near the skids is much more stable than the area of the upper deck: Alone in that of the side surface the suture line accessible to the pallet is restricted to the area of the feet through which the suture passes, the seam line is drastically shorter than in the case of pallets where the suture line circumscribes the outside of the pallet circumferentially around the entire circumference of the deck this shorter seam length corresponding to the percentage likelihood is reduced that even a shock can be made against the seam line.

Vorteilhaft kann die Naht vom äußeren Umfangsrand der Platte zu deren Mitte hin von unten nach oben verlaufen. Hierdurch wird die Stabilität der Palette verbessert, denn die erwähnten Stoßkräfte, die durch Zinken oder eine gesamte Gabel eines Flurförderfahrzeuges bei einem seitlichen Stoß auf die Palette einwirken können, belasten die Palette und insbesondere deren Naht zwischen Ober- und Unterteil nicht auf Scherung. Vielmehr stützt das Innenteil das außen nach unten gezogene Oberteil bei einem horizontal zur Plattenmitte hin gerichteten Stoß regelrecht ab, so dass die Nahtbelastung deutlich herabgesetzt ist. Aufgrund dieser reduzierten Nachbelastung sind unterschiedliche Verbindungsmöglichkeiten zwischen Ober- und Unterteil denkbar, so dass diese beiden Teile beispielsweise miteinander verschweißt oder verklebt sein können oder auch verclipst, also verrastet sein können. Insbesondere können zwei Verbindungsarten gleichzeitig Anwendung finden, beispielsweise eine Verrastung sowie eine Verklebung oder Verschweißung, so dass eine besonders zuverlässige Verbindung zwischen Ober- und Unterteil gewährleistet ist. Der vorschlagsgemäß nicht nur in einer Ebene liegende Verlauf der Verbindungsnaht erfordert beim Verschweißen oder Verkleben der beiden Ober- und Unterteile der Palette erhöhte Aufmerksamkeit bzw. kompliziertere Fertigungsanlagen. Überraschend hat sich jedoch herausgestellt, dass durch die vorschlagsgemäß erzielbare Stabilität der Palette die Fertigung der Palette anderweitig wirtschaftlicher erfolgen kann, beispielsweise durch geringere Materialstärken, so dass die verbesserte Stabilität der vorschlagsgemäßen Palette auch bei einer wirtschaftlich herzustellenden Palette erzielbar ist.Advantageously, the seam may extend from the outer peripheral edge of the plate towards its center from bottom to top. As a result, the stability of the pallet is improved, because the aforementioned impact forces that can act on the pallet by tines or an entire fork of a material handling vehicle in a lateral impact, do not burden the range and in particular the seam between the upper and lower part to shear. Rather, the inner part supports the outside pulled down top with a horizontally directed towards the center of the plate downright so that the seam load is significantly reduced. Due to this reduced afterload different connection possibilities between the upper and lower part are conceivable, so that these two parts can be welded or glued together, for example, or even clipped, so it can be locked. In particular, two types of connection can be used at the same time, for example a latching as well as a gluing or welding, so that a particularly reliable connection between upper and lower part is ensured. The proposal according to not just lying in a plane course of the seam requires welding or gluing the two upper and lower parts of the pallet increased attention or more complex manufacturing facilities. Surprisingly, however, it has been found that by the proposed achievable stability of the range, the production of the pallet can otherwise be done more economically, for example, by lower material thicknesses, so that the improved stability of the proposed range is also achievable in an economically manufacturable range.

Vorteilhaft ist die Verbindung der einzelnen Palettenteile miteinander dauerhaft ausgeführt, also als nicht lösbare Verbindung. Hierdurch wird die Stabilität der Palette verbessert. Insbesondere wenn die nicht lösbare Verbindung dicht ausgeführt wird, beispielsweise durch Verklebung oder Verschweißung der Palettenteile miteinander, wird auch die Hygiene der Palette vorteilhaft beeinflusst, da das Eindringen von Flüssigkeiten in Hohlräume der Palette, oder auch das Austreten von Gasen aus den Hohlräumen vermieden werden kann.Advantageously, the connection of the individual parts of the pallet is permanently carried out with one another, ie as a non-detachable connection. This improves the stability of the pallet. In particular, when the non-releasable connection is made tight, for example by gluing or welding the pallet parts together, the hygiene of the pallet is also favorably influenced, since the penetration of liquids into cavities of the pallet, or even the escape of gases from the cavities can be avoided ,

Vorteilhaft können am Deck oder in den Füßen der Palette Hohlräume vorgesehen sein, so dass eine besonders leichtgewichtige und materialsparende, damit wiederum eine besonders wirtschaftlich herstellbare Palette geschaffen werden kann. Die erwähnten Hohlräume sind dabei mit Aussteifungselementen versehen, die durch Ausschäumung der Hohlräume oder durch materialeinheitlich von den Palettenteilen ausgebildete Rippen oder durch separate Aussteifungsprofile, beispielsweise Metallprofile gebildet sind. Die vorschlagsgemäßen Paletten können vorteilhaft Ober- und Unterteile aufweisen, die im Spritzguss hergestellt sind. So lassen sich preisgünstig die Paletten in großer Stückzahl herstellen.Advantageously, cavities can be provided on the deck or in the feet of the pallet so that a particularly lightweight and material-saving, in turn, a particularly economically producible range can be created. The mentioned cavities are provided with stiffening elements by the foaming of the cavities or by the same material formed by the pallet parts ribs or by separate stiffening profiles, such as metal profiles are formed. The proposed pallets can advantageously have upper and lower parts, which are produced by injection molding. Thus, the pallets can be produced inexpensively in large quantities.

Ein Ausführungsbeispiel einer vorschlagsgemäßen Palette wird anhand der rein schematischen Darstellungen nachfolgend näher erläutert. Dabei zeigt

Fig. 1
Ober- und Unterteil einer Palette in auseinander gezogener, perspektivischer Darstellung, und
Fig. 2
eine fertig gestellte Palette in perspektivischer Ansicht von unten.
An embodiment of a proposed range is explained in more detail below with reference to the purely schematic representations. It shows
Fig. 1
Upper and lower part of a pallet in exploded, perspective view, and
Fig. 2
a finished pallet in perspective view from below.

In den Zeichnungen ist mit 1 insgesamt eine Palette bezeichnet, die ein als Oberteil 2 bezeichnetes Spritzgussteil sowie ein als Unterteil 3 bezeichnetes Spritzgussteil aufweist. Das Oberteil 2 bildet ein geschlossenes Deck 4 der Palette 1 aus, so dass eine hygienisch geschlossene Palettenoberfläche erzielt wird. Füße 5 sind in drei parallelen Reihen angeordnet, wobei jeweils drei Füße 5 durch längs verlaufende Kufen 6 miteinander verbunden sind.In the drawings, a total of 1 denotes a pallet having an upper part 2 designated as an injection molded part and a lower part 3 designated as an injection molded part. The upper part 2 forms a closed deck 4 of the pallet 1, so that a hygienically closed pallet surface is achieved. Feet 5 are arranged in three parallel rows, with three feet 5 are connected by longitudinal runners 6 together.

Eine Naht 7 ergibt sich durch die Trennstellen, an denen das Oberteil 2 an das Unterteil 3 grenzt und der Verlauf der Naht 7 ist aus Fig. 2 deutlich ersichtlich. Die Naht 7 verläuft am äußeren Umfang der Palette, in deren unterer Hälfte, bodennah oberhalb der Kufen 6 an den beiden Längsseiten der Palette 1 und an den beiden Stirnseiten der Palette 1 verläuft die Naht an der Unterkante der Füße 5. Insgesamt verläuft am äußeren Umfang der Palette 1 die Naht 7 stets durch die Füße 5, so dass die am äußeren Umfang zugängliche Länge der Naht 7 deutlich kürzer ist als die Umfangslänge der gesamten Palette 1, beispielsweise in Form der Umfangslänge des Decks 4.A seam 7 results from the separation points at which the upper part 2 adjoins the lower part 3 and the course of the seam 7 is clearly evident from FIG. The seam 7 extends on the outer circumference of the pallet, in the lower half, near the ground above the runners 6 on the two longitudinal sides of the pallet 1 and on the two end sides of the pallet 1, the seam runs at the lower edge of the feet 5. Overall runs on the outer periphery the pallet 1, the seam 7 always through the feet 5, so that the accessible at the outer periphery length of the seam 7 is significantly shorter as the circumferential length of the entire pallet 1, for example in the form of the circumferential length of the deck. 4

Wie anhand von Fig. 2, insbesondere auch im Vergleich zur Darstellung der Fig. 1 deutlich ist, verläuft die Naht 7 vom äußeren Umfang der Palette 1 zur Mitte der Palette 1 hin aufwärts.As is clear from Fig. 2, in particular in comparison with the illustration of FIG. 1, the seam 7 extends from the outer periphery of the pallet 1 to the center of the pallet 1 upwards.
