Description

Die vorliegende Erfindung betrifft eine Kufenpalette gemäß dem Oberbegriff des Anspruchs 1, wobei die Kufenpalette zur Handhabung mittels Hubstapler, Regalbediengerät o.dgl. Transportmittel eingerichtet ist und mit einem auf Stützfüßen einer Mittelkufe und zwei Außenkufen aufliegenden Palettenboden zur Abstützung eines Innenbehälters eines Transport- und Lagerbehälters ausgestattet ist.The present invention relates to a runner pallet according to the preamble of claim 1, wherein the runners pallet for handling by means of a lift truck, stacker crane or the like. Transport means is set up and equipped with a resting on support feet a center skid and two outer skids pallet base for supporting an inner container of a transport and storage container.

Kufenpaletten der eingangs genannten Art, die aus einem Palettenboden mit daran angeordneten, als Mittelkufe und Außenkufen ausgeführten Kufen versehen sind, werden bei der konfektionierten Herstellung von Transport- und Lagerbehältern in vormontierter Form bereitgestellt, mit dem Außenmantel versehen und anschließend mit dem Innenbehälter aus Kunststoff bestückt. Bei den bekannten Transport- und Lagerbehältern werden zur Herstellung der Kufenpalette sowie zur Verbindung des Außenmantels mit der fertiggestellten Kufenpalette voneinander unabhängige Verbindungsvorgänge ausgeführt. Insbesondere wird der Palettenboden zunächst einerseits mit den Kufen verbunden, um dann in einem von dem ersten Verbindungsvorgang unabhängigen Verbindungsvorgang mit dem Außenmantel verbunden zu werden. In der Regel werden derartige Verbindungen als Schraubenverbindungen durchgeführt, so dass also zunächst eine Verschraubung der Palettenkufen mit dem Palettenboden und anschließend einer Verschraubung des Palettenbodens mit dem Außenmantel ausgeführt wird. Damit erweist sich die Herstellung der bekannten konfektionierten Transport- und Lagerbehälter als entsprechend aufwendig.Skid pallets of the type mentioned above, which are arranged on a pallet base arranged thereon, designed as center skids and skids runners are provided in the prefabricated production of transport and storage containers in pre-assembled form, provided with the outer shell and then fitted with the inner container made of plastic , In the known transport and storage containers independent connection operations are carried out for the preparation of the runners pallet and for connecting the outer shell with the finished runner pallet. In particular, the pallet base is firstly connected on the one hand to the runners, in order then to be connected to the outer jacket in a connection process independent of the first connection process. Usually Such compounds are carried out as screw connections, so that therefore first a screwing of the pallet skids with the pallet base and then a screw connection of the pallet base is carried out with the outer shell. Thus, the production of the known prefabricated transport and storage containers proves to be correspondingly expensive.

Schließlich kommt einer Kufenpalette der eingangs genannten Art auch die Aufgabe zu, mit geeigneten Hubstapeleinrichtungen eine handhabbare Plattform zur Lagerung und zum Transport der aus Kunststoff gefertigten und daher vergleichsweise verletzlichen Innenbehälter zur Verfügung zu stellen, so dass derartige Kufenpaletten in Kombination mit dem Außenmantel zum Schutz des Innenbehälters vor Beschädigungen dienen. Dabei sollen die als Kufenpalette ausgeführten Untergestelle der Tatsache in besonderer Weise Rechnung tragen, dass aufgrund der Handhabung der Transport- und Lagerbehälter ein nicht unbeachtliches Risiko für die Innenbehälter besteht, beschädigt zu werden. Das palettenartige Untergestell stellt somit einen Schutzschild oder Protektor dar, der insbesondere Stoßbelastungen absorbieren soll, die auf den Innenbehälter beispielsweise bei einem Aufprall des Transport- und Lagerbehälters auf den Boden infolge unsachgemäßer Handhabung des Transport- und Lagerbehälters einwirken können. Hierzu muss das Untergestell in der Lage sein, entsprechende Belastungen aufzunehmen und auch noch nach einem aufgetretenen Belastungsfall nach wie vor als Handhabungsplattform für den Flüssigkeitsbehälter zu funktionieren.Finally, a runners pallet of the type mentioned also has the task to provide with suitable Hubstapeleinrichtungen a manageable platform for storage and transport of plastic made and therefore relatively vulnerable inner container available, so that such runner pallets in combination with the outer jacket to protect the Inner container from damage serve. In this case, run as runners pallet bases to take into account the fact in a special way that due to the handling of the transport and storage containers is a not inconsiderable risk for the inner container to be damaged. The pallet-like undercarriage thus represents a protective shield or protector, which is intended in particular to absorb shock loads which can act on the inner container, for example in the event of an impact of the transport and storage container on the ground due to improper handling of the transport and storage container. For this purpose, the undercarriage must be able to absorb corresponding loads and still function as a handling platform for the liquid container even after a load case has occurred.

Aus der DE 203 16 883 U1 ist eine Kufenpalette bekannt, die zur Handhabung mittels Hubstapler, Regalbediengerät oder dergleichen Transportmittel eingerichtet ist und mit einem auf Stützfüßen, einer Mittelkufe und zwei Außenkufen aufliegenden Palettenboden zur Abstützung eines Innenbehälters eines Transport- und Lagerbehälters ausgestattet ist, wobei die Mittelkufe und die Außenkufen mittels einer Kufenbrücke in definierter Relativanordnung miteinander verbunden sind und eine Palettenbasis bilden.From the DE 203 16 883 U1 a skid pallet is known, which is adapted for handling by means of a lift truck, stacker crane or similar means of transport and is equipped with a resting on support legs, a center skid and two outer skids pallet base for supporting an inner container of a transport and storage container, wherein the center skid and the outer runners by means of a Skid bridge are connected to each other in a defined relative arrangement and a Form pallet base.

Aus der DE 100 38 464 A1 ist eine Kufenpalette bekannt, die, wie insbesondere in Fig. 6 dargestellt, eine Mittelkufe und zwei Außenkufen aufweist, welche über eine Kufenbrücke miteinander verbunden sind und zusammen mit der Kufenbrücke eine Palettenbasis bilden, die mit einem Palettenboden kraftschlüssig verbunden ist.From the DE 100 38 464 A1 is known a runners pallet, which, in particular in Fig. 6 shown, having a center runner and two outer runners, which are connected to each other via a runner bridge and together with the runner bridge form a pallet base, which is non-positively connected to a pallet base.

Aus der WO 99/35042 A1 ist eine Kunststoffpalette bekannt, die als Rahmenpalette ausgebildet ist, die mit einem geschlossenen umlaufend ausgebildeten Grundrahmen, auf dem Füße angeordnet sind, die über eine Steckverbindung mit einem Palettenboden verbunden sind.From the WO 99/35042 A1 is known a plastic pallet, which is designed as a frame pallet, which are arranged with a closed circumferentially formed base frame on the feet, which are connected via a plug connection with a pallet base.

Die US 6 109 190 A zeigt eine Kunststoffpalette, die zweiteilig ausgebildet ist, mit einem Palettenunterteil und einem Palettenoberteil, die über eine Rastverbindung miteinander verbunden werden.The US Pat. No. 6,109,190 A shows a plastic pallet, which is formed in two parts, with a pallet base and a pallet upper part, which are connected to one another via a latching connection.

Aus der EP 2 090 520 A1 ist eine Kunststoffpalette bekannt, die als Rahmenpalette ausgebildet ist, mit einem Grundrahmen, auf dem Stützfüße angeordnet sind, die über eine Steckverbindung mit einem Palettenboden verbunden sind.From the EP 2 090 520 A1 a plastic pallet is known, which is designed as a frame pallet, with a base frame, are arranged on the support legs, which are connected via a plug connection with a pallet base.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die konfektionierte Herstellung von Transport- und Lagerbehältern zu vereinfachen, die darüber hinaus als Kufenpalette ausgeführte Untergestelle für einen Transport- und Lagerbehälter für Flüssigkeiten aufweisen, die eine erhöhte Stabilität aufweisen und die eine Steckverbindung zwischen Palettenbasis und Stützfüßen ermöglichen, die die Erzeugung großer Haltekräfte ermöglicht, um somit die Bereitstellung von Transport- und Lagerbehältern für Flüssigkeiten zu ermöglichen, die eine erhöhte Sicherheit gegen ein durch mangelnde Stabilität des Untergestells bedingtes Behälterversagen gewährleisten und sich in besonderer Weise zum Transport und zur Lagerung von Gefahrgut eignen.The present invention has for its object to simplify the prefabricated production of transport and storage containers, which also designed as runners pallet bases for a transport and storage containers for liquids, which have increased stability and allow a plug connection between the pallet base and support legs which allows the generation of large holding forces, thus enabling the provision of transport and storage containers for liquids, which ensure increased security against a lack of stability of the undercarriage caused container failure and are particularly suitable for the transport and storage of dangerous goods.

Zur Lösung dieser Aufgabe weist die erfindungsgemäße Kufenpalette die Merkmale des Anspruchs 1 auf.To solve this problem, the runner pallet according to the invention has the features of claim 1.

Erfindungsgemäß ist die Kufenpalette so ausgeführt, dass die Mittelkufe und die Außenkufen mittels einer Kufenbrücke in definierter Relativanordnung miteinander verbunden sind und eine unabhängig vom Palettenboden handhabbare Palettenbasis bilden. Weiterhin weist der Palettenboden zur Herstellung einer kraftschlüssigen Steckverbindung mit der Palettenbasis den Stützfüßen zugeordnete Eingriffseinrichtungen auf, die mit zugeordneten Eingriffseinrichtungen der Stützfüße zusammenwirken.According to the invention, the runner pallet is designed so that the center runner and the outer runners are connected to one another in a defined relative arrangement by means of a runner bridge and form a pallet base which can be handled independently of the pallet base. Furthermore, the pallet base for producing a non-positive connector with the pallet base on the support feet associated engagement means which cooperate with associated engagement means of the support legs.

Aufgrund der erfindungsgemäßen Ausführungsform der Kufenpalette ist es möglich, für die konfektionierte Fertigung eines Transport- und Lagerbehälters eine Kufenpalette bereitzustellen, die die aus der Mittelkufe und den Außenkufen gebildete Palettenbasis in einem mechanischen Verbund mit dem Palettenboden aufweist, ohne das hierzu die Erstellung einer Verbindung mit Handhabung zusätzlicher Verbindungselemente notwendig wird. Vielmehr ist es möglich, den mechanischen gefügten Verbund zwischen der Palettenbasis und dem Palettenboden dadurch herzustellen, dass der Palettenboden in definierter Relativanordnung auf die Palettenbasis aufgesetzt wird und zur Sicherung des mechanischen Verbunds zwischen der Palettenbasis und dem Palettenboden eine Steckverbindung zwischen dem Palettenboden und der Palettenbasis hergestellt wird. Diese Steckverbindung erfolgt durch den Eingriff der Eingriffseinrichtungen des Palettenbodens in die entsprechenden bzw. zugeordneten Eingriffseinrichtungen der Stützfüße der Palettenbasis. Damit ist die einfache Herstellung einer Stapelanordnung zwischen dem Palettenboden und der Palettenbasis ausreichend, um eine für die weitere konfektionierte Herstellung des Transport- und Lagerbehälters handhabbare Kufenpalette zur Verfügung zu stellen.Due to the embodiment of the runner pallet according to the invention, it is possible to provide for the prefabricated production of a transport and storage container skids pallet, which has the pallet base formed from the center skid and the outer runners in a mechanical composite with the pallet base, without the creation of a connection with Handling additional fasteners is necessary. Rather, it is possible to produce the mechanical bonded composite between the pallet base and the pallet base in that the pallet base is placed in a defined relative arrangement on the pallet base and made to secure the mechanical bond between the pallet base and the pallet base a plug connection between the pallet base and the pallet base becomes. This connector is made by the engagement of the engagement means of the pallet base in the corresponding or associated engagement means of the support feet of the pallet base. Thus, the simple production of a stacking arrangement between the pallet base and the pallet base is sufficient to provide a manageable for the further prefabricated production of the transport and storage container runners pallet available.

Insbesondere ist die Steckverbindung ausreichend, um den mechanischen Verbund des Palettenbodens mit der Palettenbasis während der weiteren Montage, also der nachfolgenden Anordnung des Außenmantels auf dem Palettenboden zu sichern. Die endgültige, dauerhafte Fixierung des Palettenbodens auf der Palettenbasis erfolgt dann zugleich mit Herstellung der Verbindung zwischen dem Palettenboden und dem Außenmantel, beispielsweise dadurch, dass zur Verschraubung des Außenmantels mit dem Palettenboden Verbindungsschrauben verwendet werden, die durch den Palettenboden hindurch in die Stützfüße der Palettenbasis eindringen. Damit wird insgesamt ein Verbindungsaufbau geschaffen, bei dem der Palettenboden sandwichartig zwischen dem Außenmantel und den Stützfüßen aufgenommen sind, die durch den Palettenboden hindurch mit dem Außenmantel über Verbindungselemente miteinander verbunden sind. Auch führt die Steckverbindung zu einer Erhöhung der Eigenstabilität der Kufenpalette.In particular, the connector is sufficient to the mechanical bond of the pallet base with the pallet base during further assembly, so the subsequent arrangement of the outer shell on the Secure pallet floor. The final, permanent fixation of the pallet base on the pallet base then takes place at the same time establishing the connection between the pallet base and the outer shell, for example by the fact that for screwing the outer shell to the pallet base connecting screws are used, which penetrate through the pallet base into the support feet of the pallet base , Thus, a total connection is created in which the pallet base are sandwiched between the outer shell and the support legs, which are connected by the pallet bottom through with the outer shell via connecting elements. Also, the connector leads to an increase in the inherent stability of the runners pallet.

Der besondere Vorteil der erfindungsgemäßen Kufenpalette liegt somit darin, dass durch die erfindungsgemäße Ausgestaltung quasi eine Vormontage der Kufenpalette erreicht wird, die den Verbund zwischen der Palettenbasis und dem Palettenboden zumindest solange sichert, bis eine endgültige Verbindung zwischen der Palettenbasis und dem Palettenboden über die Verbindungselemente hergestellt ist, die den Außenmantel mit den Stützfüßen der Palettenbasis verbinden.The particular advantage of the runner pallet according to the invention is thus that the pre-assembly of the runner pallet is virtually achieved by the inventive design that secures the bond between the pallet base and the pallet base at least until a final connection between the pallet base and the pallet base made via the connecting elements is that connect the outer shell with the support feet of the pallet base.

Da der Palettenboden den Stützfüßen der Palettenbasis zugeordnete Eingriffskörper aufweist, die in Ausnehmungen der Stützfüße derart eingreifen, dass zwischen einer Umfangsfläche der Eingriffskörper und einer Oberfläche der Ausnehmung eine Klemmkraft erzeugt wird, kann vorteilhafter Weise zur räumlichen Anordnung bzw. Ausbildung der Steckverbindung zwischen dem Palettenboden und der Palettenbasis ein durch die Stützfußkörper definierter Raum genutzt werden.Since the pallet base has the supporting feet of the pallet base associated engagement body, which engage in recesses of the support legs such that between a peripheral surface of the engagement body and a surface of the recess, a clamping force is generated, can advantageously for the spatial arrangement or design of the connector between the pallet base and the pallet base a space defined by the support foot body can be used.

Erfindungsgemäß weisen die Eingriffskörper des Palettenbodens einen konischen Körper mit elliptischem Querschnitt, der derart in die Ausnehmungen des Stützfußes eingreift, dass sich ein linienförmiger Kontaktbereich zwischen der Umfangsfläche des Eingriffskörpers und einer Kontaktoberfläche der Ausnehmungen ergibt, wobei der Kontaktbereich durch den Schnittpunkt der langen Ellipsenachse des elliptischen Querschnitts mit der Kontaktfläche verläuft. Einerseits ermöglicht der konisch ausgebildete Eingriffskörper des Palettenbodens eine Ausbildung eines Klemmsitzes zwischen dem Eingriffskörper des Palettenbodens und der Ausnehmung des Stützfußes, derart, dass bereits schwerkraftbedingt die zur Herstellung des mechanischen Verbunds zwischen dem Palettenboden und der Palettenbasis notwendige Haltekraft erzeugt wird und gegebenenfalls allenfalls ein geringes Nachpressen nötig ist, um den mechanischen Verbund für die nachfolgende Montage ausreichend zu sichern. Darüber hinaus ermöglicht die linienförmige Ausbildung des Kontaktbereichs zwischen der Umfangsfläche des Eingriffskörpers und der Kontaktoberfläche der Ausnehmung die Erzeugung großer Haltekräfte. Eine ähnlich vorteilhafte Wirkung wird auch - obwohl möglicherweise in geringerem Ausmaß - erreicht, wenn der konische Eingriffskörper einen runden oder abgerundeten Querschnitt aufweist. Wesentlich ist in jedem Fall die Ausbildung eines linienförmigen Kontaktbereichs.According to the invention, the engagement bodies of the pallet base have a conical body with an elliptical cross-section which engages in the recesses of the support leg such that a line-shaped contact area results between the peripheral surface of the engagement body and a contact surface of the recesses, wherein the contact area passing through the intersection of the long ellipse axis of the elliptical cross section with the contact surface. On the one hand, the conically formed engagement body of the pallet base allows a clamping fit to be formed between the engagement body of the pallet base and the recess of the support foot in such a way that the holding force required to produce the mechanical bond between the pallet base and the pallet base is already generated by gravity and if necessary, at most, a slight repressing is necessary to secure the mechanical bond for subsequent assembly sufficient. In addition, the linear formation of the contact area between the peripheral surface of the engagement body and the contact surface of the recess enables the generation of large holding forces. A similar advantageous effect is also achieved - although possibly to a lesser extent - when the conical engaging body has a round or rounded cross-section. It is essential in any case the formation of a linear contact area.

Wenn zumindest ein Eingriffskörper des Palettenbodens als Zentrierfortsatz ausgebildet ist, der in einer Ausnehmung der Palettenbasis eingreift, kann gleichzeitig mit Herstellung der Steckverbindung zwischen dem Palettenboden und der Palettenbasis eine exakte Relativpositionierung der Palettenbasis gegenüber dem Palettenboden in der Verbindungsebene zwischen der Palettenbasis und dem Palettenboden realisiert werden. Insbesondere kann der als Zentrierfortsatz verwendete Eingriffskörper unabhängig von den Eingriffskörpers ausgebildet sein, die zur Herstellung des mechanischen Verbunds, also der Steckverbindung dienen, so dass der Zentriervorgang keinen Einfluss hat auf die Ausbildung der Haltekräfte und somit auch nicht die Ausbildung ausreichender Haltekräfte beeinträchtigen kann.If at least one engagement body of the pallet base is designed as a centering extension which engages in a recess of the pallet base, an exact relative positioning of the pallet base relative to the pallet base in the connection plane between the pallet base and the pallet base can be realized simultaneously with production of the connector between the pallet base and the pallet base , In particular, the engagement body used as Zentrierfortsatz be formed independently of the engagement body, which serve for the production of the mechanical composite, ie the connector, so that the centering has no effect on the formation of holding forces and thus can not affect the formation of sufficient holding forces.

Bei einer besonders bevorzugten Ausführungsform der Kufenpalette sind der Palettenboden und die Palettenbasis als Kunststoffteile hergestellt, so das besonders vorteilhaft eine parallele Herstellung der Palettenbasis und des Palettenbodens in einem simultanen Formgebungs-, insbesondere Spritzgießvorgang, möglich ist und unmittelbar nachfolgend der parallelen Herstellung des Palettenbodens und der Palettenbasis durch Herstellung einer Stapelanordnung zwischen dem Palettenboden und der Palettenbasis die Kufenpalette als Zwischenprodukt für die weitere konfektionierte Herstellung des Transport- und Lagerbehälters herstellbar ist. Damit kann insbesondere eine separate Lagerhaltung von Palettenböden und Palettenbasen entfallen. Vielmehr erfolgt unmittelbar nach Erzeugung der Palettenböden und der Palettenbasis deren Vereinigung zu der erfindungsgemäßen Kufenpalette.In a particularly preferred embodiment of the runner pallet, the pallet base and the pallet base are manufactured as plastic parts, so that particularly advantageously a parallel production of the pallet base and the pallet base in a simultaneous shaping, in particular injection molding, is possible and immediately following the parallel production of the pallet base and the pallet base by producing a stacking arrangement between the pallet base and the pallet base the runners pallet produced as an intermediate for the further prefabricated production of the transport and storage container is. This can be omitted in particular a separate storage of pallet floors and pallet bases. Rather, immediately after the production of the pallet floors and the pallet base their association with the runner pallet invention.

Insbesondere bei einer Ausgestaltung des Palettenbodens und der Palettenbasis aus Kunststoff erweist es sich als vorteilhaft, wenn die Kufenbrücke der Palettenbasis zur Aufsteifung des Palettenbodens mit einer Verstärkungseinlage versehen ist. Damit können gegebenenfalls bestehende Festigkeitsdefizite des Palettenbodens ausgeglichen werden, ohne dass eine Beeinträchtigung des vorstehend beschriebenen Montagevorgangs des Palettenbodens und der Palettenbasis durch Herstellung einer Stapelanordnung beeinträchtigt würde. Vielmehr kann die Verstärkungseinlage bei Herstellung des Verbunds zwischen der Palettenbasis und des Palettenbodens als Zwischenlage eingefügt werden.In particular, in an embodiment of the pallet base and the pallet base made of plastic, it proves to be advantageous if the runner bridge of the pallet base is provided for stiffening the pallet base with a reinforcing insert. Thus, if necessary, existing strength deficits of the pallet base can be compensated for without adversely affecting the above-described assembly process of the pallet base and the pallet base by producing a stack arrangement. Rather, the reinforcing insert can be inserted as an intermediate layer when producing the composite between the pallet base and the pallet base.

Dabei ist es besonders vorteilhaft, wenn die Verstärkungseinlage aus einer vorzugsweise aus Metall hergestellten Bodentraverse besteht, die auf einer die Außenkufen miteinander verbindenden, einer Unterseite des Palettenbodens zugewandten Stützfläche der Kufenbrücke angeordnet ist. Damit kann die Einfügung der Verstärkungseinlage während des Montagevorgangs durch einfaches Auflegen der Verstärkungseinlage auf die Kufenbrücke erfolgen.It is particularly advantageous if the reinforcing insert consists of a preferably made of metal floor crossmember, which is arranged on a the outer skids interconnecting, a bottom of the pallet base facing support surface of the runner bridge. Thus, the insertion of the reinforcing insert during the assembly process by simply placing the reinforcing insert on the skids bridge done.

Besonders vorteilhaft ist es, wenn die Bodentraverse zur Relativpositionierung formschlüssig mit der Kufenbrücke verbunden ist und zur Aussteifung des Palettenbodens kraftschlüssig mit dem Palettenboden verbunden ist. Dabei erfolgt die Herstellung der formschlüssigen Verbindung gleichzeitig mit dem Auflegen der Bodentraverse und zum anderen wird sichergestellt, dass über die kraftschlüssige Verbindung mit dem Palettenboden tatsächlich die beabsichtigte versteifende Wirkung auf den Palettenboden erzielt wird.It is particularly advantageous if the floor cross member is positively connected to the runner bridge for relative positioning and is non-positively connected with the pallet floor for stiffening the pallet floor. In this case, the production of positive connection occurs simultaneously with the laying of the floor cross-beam and on the other hand it is ensured that the intended stiffening effect on the pallet floor is actually achieved via the non-positive connection with the pallet floor.

Wenn die in den Stützfüßen der Palettenbasis ausgebildeten Ausnehmungen, die zur Aufnahme der Eingriffskörper des Palettenbodens dienen, zur Ausbildung einer Aufstandsfläche der Stützfüße mit einer Bodenwandung versehen sind, ist es möglich, die insbesondere bei einem mit Flüssigkeit befüllten Innenbehälter des Transport- und Lagerbehälters die von den Stützfüßen auf den Untergrund ausgeübte Flächenpressung zu reduzieren.If the formed in the support feet of the pallet base recesses, which serve to receive the engagement body of the pallet base, are provided to form a footprint of the support legs with a bottom wall, it is possible, in particular in a filled with liquid inner container of the transport and storage container of To reduce the surface pressure applied to the support feet on the ground.

Als besonders vorteilhaft erweist es sich auch, wenn die Eckfüße der Palettenbasis bei gleicher Breite wie die Mittelfüße eine größere Länge als die Mittelfüße aufweisen, so dass über die vergrößerte Länge der Eckfüße eine weitere Versteifung des Palettenbodens erzielt wird.It proves to be particularly advantageous if the corner feet of the pallet base have the same width as the middle feet a greater length than the middle feet, so that over the increased length of the corner feet further stiffening of the pallet base is achieved.

Hinsichtlich der Ausgestaltung des Palettenbodens erweist es sich als vorteilhaft, wenn der Palettenboden einen Mittelabschnitt und einen vorderen und hinteren Randabschnitt aufweist, wobei in einer Auflagefläche des Palettenbodens im Mittelabschnitt Längssicken und in den Randabschnitten parallel zu den Rändern des Palettenbodens verlaufende Quersicken ausgebildet sind, wobei zur Ausbildung einer erhöhten Steifigkeit die Querschnittshöhe der Quersicken größer ausgebildet ist als die Querschnittshöhe der Längssicken im Mittelabschnitt und ein entsprechender Überstand der Quersicken gegenüber der Unterseite des Mittelabschnitts ausgebildet ist. Hier wird erreicht, dass die dem Untergrund zugewandten Unterseiten der Quersicken und der Kufenbrücke in einer gemeinsamen Ebene angeordnet sind, so dass bei der Aufnahme der Kufenpalette durch eine Hubstaplereinrichtung die Zinken der Hubstaplereinrichtung in gleicher Weise gegen die Unterseite der Quersicken anliegen wie gegen die Unterseite der Kufenbrücke und die jeweils in den Kontaktbreichen wirkende Flächenpressung vorteilhaft reduziert wird.With regard to the design of the pallet base, it proves to be advantageous if the pallet base has a central portion and a front and rear edge portion, wherein formed in a support surface of the pallet base in the middle section longitudinal beads and in the edge portions parallel to the edges of the pallet base transverse beads, wherein the Forming an increased rigidity, the cross-sectional height of the transverse beads is formed larger than the cross-sectional height of the longitudinal beads in the central portion and a corresponding projection of the transverse beads is formed opposite the underside of the central portion. Here, it is achieved that the underside facing the ground of the cross beads and the runner bridge are arranged in a common plane, so that when receiving the runners pallet by a Hubstaplereinrichtung the tines of the Hubstaplereinrichtung abut in the same way against the underside of the transverse beads as against the underside of the Skids bridge and each in the contact surfaces acting surface pressure is advantageously reduced.

Dies ist insbesondere dann der Fall, wenn vorteilhaft der Überstand so bemessen ist, dass er dem Abstand der Stützfläche der Kufenbrücke von der Unterseite des Mittelabschnitts entspricht.This is the case in particular if, advantageously, the projection is dimensioned such that it corresponds to the distance of the support surface of the runner bridge from the underside of the middle section.

Wenn die Mittelkufe eine die Stützfüße der Mittelkufe miteinander verbindende Kufenbasis aufweist, deren Höhe geringer ausgebildet ist als die Höhe der die Stützfüße der Außenkufen miteinander verbindenden Kufenbasis, wird erreicht, dass auch bei einem in Folge der Gewichtsbelastung durch einen mit Flüssigkeit gefüllten Innenbehälter im Mittelabschnitt nach unten ausgelenkten Palettenboden ein immer noch ausreichender lichter Abstand zwischen der Unterseite des Palettenbodens und der Kufenbasis gegeben ist, so dass dann auch bei einem Unterfahren des Palettenbodens mit den Zinken einer Hubstaplereinrichtung quer zur Längsrichtung des Transport- und Lagerbehälters das Risiko einer Kollision der Staplerzinken mit der Kufenpalette reduziert wird.When the center runner has a runner base connecting the support feet of the center runner whose height is less than the height of the runner base connecting the support legs of the outer runners, it is achieved that even if the inner container in the middle section is filled with liquid as a result of the weight load Given below deflected pallet floor still sufficient clearance between the bottom of the pallet base and the runner base is given, so that then even when driving under the pallet bottom with the tines of a Hubstaplereinrichtung transversely to the longitudinal direction of the transport and storage container the risk of collision of the forklift tines with the Skid pallet is reduced.

Nachfolgend wird eine bevorzugte Ausführungsform der Kufenpalette anhand der beiliegenden Zeichnung näher erläutert.Hereinafter, a preferred embodiment of the runner pallet will be explained in more detail with reference to the accompanying drawings.

An der oberen Bodenwand 27 ist ein mit einem Deckel 28 verschließbarer Einfüllstutzen 29 angeformt. Die Frontwand 22 weist an einer Einwölbung 30 im unteren Abschnitt der Frontwand 22 einen Auslaufstutzen 31 auf, der zum Anschluss einer Entnahmearmatur 32 dient. Fig. 1 shows a usable as disposable and reusable container transport and storage container 20 for liquids, which has an exchangeable cuboid inner container 21 made of plastic with a front wall 22, a rear wall 23 and two side walls 24, 25 and a lower and an upper bottom wall 26, 27th On the upper bottom wall 27 a closable with a cover 28 filler neck 29 is formed. The front wall 22 points to a concavity 30 in the lower Section of the front wall 22 an outlet connection 31, which serves to connect a removal fitting 32.

Der Innenbehälter 21 ist mit seiner unteren Bodenwand 26 auf einem Palettenboden 33 eines als Kufenpalette 34 ausgebildeten Untergestells angeordnet. Die Kufenpalette 34 weist zur Abstützung des Palettenbodens 33 eine Mittelkufe 35 und zwei Außenkufen 36, 37 auf. Zum Schutz ist der auf dem Palettenboden 33 angeordnete Innenbehälter 21 in einem hier als Gittermantel ausgebildeten Außenmantel 38 aufgenommen, der sich kreuzende horizontale und vertikale Gitterstäbe 39 und 40 aufweist. Zur Verbindung des Außenmantels 38 mit der Kufenpalette 34 ist ein aus horizontalen Gitterstäben 39 rahmenartig ausgebildeter Unterrand 65 des Außenmantels 38 mit der Mittelkufe 35 und den Außenkufen 36, 37 beispielsweise mittels als Schrauben 66 ausgeführten Verbindungselementen verbunden, wobei ein Umfangsrand 67 des Palettenbodens 33 sandwichartig zwischen der Mittelkufe 35 und den Außenkufen 36, 37 aufgenommen ist.The inner container 21 is arranged with its lower bottom wall 26 on a pallet base 33 of a base frame 34 designed as a pedestal. The runner pallet 34 has, for supporting the pallet base 33, a center runner 35 and two outer runners 36, 37. For protection, the inner container 21 arranged on the pallet base 33 is accommodated in an outer casing 38, which is designed here as a grate casing and has intersecting horizontal and vertical bars 39 and 40. To connect the outer shell 38 with the runners pallet 34 is a horizontal bar 39 formed like a lower edge 65 of the outer shell 38 with the center skid 35 and the outer runners 36, 37, for example by means of screws 66 designed as connecting elements, wherein a peripheral edge 67 of the pallet base 33 sandwiched between the center skid 35 and the outer runners 36, 37 is received.

Wie aus Fig. 3 hervorgeht, die die in Fig. 2 dargestellte Kufenpalette 34 in Explosionsdarstellung zeigt, besteht die Kufenpalette 34 im Falle des dargestellten Ausführungsbeispiels aus drei Komponenten, nämlich einer die Mittelkufe 35 und die beiden Außenkufen 36, 37 umfassenden Palettenbasis 41, dem Palettenboden 33 und einer Bodentraverse 42. Die Palettenbasis 41 weist zur Herstellung eines mechanischen Verbunds zwischen der Mittelkufe 35 und den beiden Außenkufen 36, 37 eine jeweils den Zwischenraum zwischen der Mittelkufe 35 und den beiden Außenkufen 36, 37 überspannende Kufenbrücke 43 auf, die im vorliegenden Fall einen Mittelfuß 44 der Mittelkufe 35 mit den Mittelfüßen 44 der beiden Außenkufen 36, 37 verbindet. Neben dem Mittelfuß 44 weisen die Mittelkufe 35 und die beiden Außenkufen 36, 37 an den axialen Enden einer Kufenbasis 45 Außenfüße 46, 47 auf. Dabei ist im Falle des vorliegenden Ausführungsbeispiels der frontseitig an der Mittelkufe 35 ausgebildete Außenfuß 46 so ausgebildet, dass er eine benachbart dem Auslaufstutzen 31 ( Fig. 1 ) des Innenbehälters 21 im Palettenboden 33 ausgebildete Bodenabsenkung 40 aufnehmen kann. Wie ferner einer Zusammenschau der Fign. 2 und 3 zu entnehmen ist, bilden die Außenfüße 46, 47 der beiden Außenkufen 36, 37 Eckfüße 49 der Kufenpalette 34 aus.How out Fig. 3 that the in Fig. 2 shown runners pallet 34 in exploded view, the runners pallet 34 in the case of the illustrated embodiment of three components, namely a center runner 35 and the two outer runners 36, 37 comprehensive pallet base 41, the pallet base 33 and a floor cross member 42. The pallet base 41 points to the production a mechanical composite between the center skid 35 and the two outer skids 36, 37 each a gap between the center skid 35 and the two outer runners 36, 37 spanning skids bridge 43, which in the present case a metatarsus 44 of the center skid 35 with the middle feet 44 of the two Outside skids 36, 37 connects. In addition to the middle foot 44, the center runner 35 and the two outer runners 36, 37 have outside feet 46, 47 at the axial ends of a runner base 45. In this case, in the case of the present embodiment, the outer foot 46 formed on the front side of the center runner 35 is designed such that it has an adjacent one Outlet 31 ( Fig. 1 ) of the inner container 21 in the pallet bottom 33 trained bottom lowering 40 can accommodate. Likewise, a synopsis of the FIGS. 2 and 3 can be seen, form the outer feet 46, 47 of the two outer runners 36, 37 corner feet 49 of the runners pallet 34.

Wie Fig. 3 zeigt, weist der Palettenboden 33 an seiner Unterseite 50 Eingriffskörper 51 auf, die so angeordnet sind, dass sie eine mit Ausnehmungen 52 in den Eckfüßen 49 und dem hinteren Außenfuß 47 der Mittelkufe 35 übereinstimmende Relativanordnung aufweisen und bei geeigneter Ausrichtung des Palettenbodens 33 gegenüber der Palettenbasis 41 in einer Stapelanordnung des Palettenbodens 33 auf der Palettenbasis 41 in die Ausnehmungen 52 der Eckfüße 49 abgesenkt werden können. Zur Versteifung des Palettenbodens 33 wird vor Herstellung der Stapelanordnung des Palettenbodens 33 auf der Palettenbasis 41 die Bodentraverse 42 auf eine Stützfläche 53 der Kufenbrücke 43 aufgelegt. Dabei wird eine definierte Positionierung der Bodentraverse 42 auf der Kufenbrücke 43 dadurch erreicht, dass eine formschlüssige Verbindung zwischen in Fig. 3 nicht näher dargestellten Ausnehmungen in der Bodentraverse 42 und zugeordneten, aus der Stützfläche 53 vorstehenden Noppen 54 hergestellt wird. Somit ist die Bodentraverse 42 so auf der Kufenbrücke 43 positioniert, dass bei einer Anordnung des Palettenbodens 33 auf der Palettenbasis 41, derart, dass ein in Fig. 13 dargestellter, an der Unterseite 50 des Palettenbodens 33 ausgebildeter Zentrierfortsatz 55 in eine zugeordnete Zentrieraufnahme 56 der Bodentraverse 42 eingreift, gleichzeitig mit dem Absenken der Eingriffskörper 51 des Palettenbodens 33 in die Ausnehmungen 52 der Palettenbasis 41 Krafteinleitungslaschen 57, die an den axialen Enden der Bodentraverse 42 ausgebildet sind, kraftschlüssig in zugeordnete, hier nicht näher dargestellt Ausnehmungen in der Unterseite 50 des Palettenbodens 33 eingreifen.As Fig. 3 shows, the pallet base 33 on its underside 50 engagement body 51 which are arranged so that they have a recesses 52 in the corner feet 49 and the rear outer leg 47 of the center skid 35 matching relative arrangement and with proper alignment of the pallet base 33 relative to the pallet base 41 in a stacking arrangement of the pallet base 33 on the pallet base 41 in the recesses 52 of the corner feet 49 can be lowered. To stiffen the pallet base 33, the floor cross member 42 is placed on a support surface 53 of the runner bridge 43 before the stacking arrangement of the pallet base 33 is produced on the pallet base 41. In this case, a defined positioning of the floor cross member 42 on the runner bridge 43 is achieved in that a positive connection between in Fig. 3 not shown recesses in the floor cross member 42 and associated, from the support surface 53 projecting nubs 54 is made. Thus, the floor cross member 42 is positioned on the runner bridge 43, that in an arrangement of the pallet base 33 on the pallet base 41, such that a in Fig. 13 illustrated, formed on the bottom 50 of the pallet base 33 centering extension 55 engages in an associated centering 56 of the floor cross member 42, simultaneously with the lowering of the engagement body 51 of the pallet base 33 in the recesses 52 of the pallet base 41 force introduction tabs 57, at the axial ends of the floor crossbeam 42nd are formed, frictionally engage in associated, not shown here recesses in the bottom 50 of the pallet base 33.

Wie aus einer Zusammenschau der Fig. 6, 7 und 8 deutlich wird, weisen die Eingriffskörper 51 eine kegelstumpfförmige Gestalt mit elliptischem Querschnitt 57 auf. Dabei ist der elliptische Querschnitt 57 so in der Ausnehmung 52 des Eckfußes 49 orientiert, dass die lange Ellipsenachse b einen Schnittpunkt mit einer im Bereich des Eingriffskörpers 51 im Wesentlichen ebenen Kontaktoberfläche 58 der Ausnehmung 52 bildet und sich ein im Wesentlichen linienförmiger Kontaktbereich 59 ausbildet. Aufgrund der kegelstumpfförmig ausgebildeten Eingriffskörper 51 und, wie insbesondere in Fig. 8 zu erkennen ist, den keilförmig zueinander angestellten gegenüberliegenden Kontaktwänden 58 der Ausnehmung 52 wird nach Anlage des Eingriffskörpers 51 gegen die Kontaktwände 58 mit zunehmender Absenkung des Eingriffskörpers 51 in die Ausnehmung 52 eine größer werdende Klemmkraft oder Haltekraft zwischen dem Palettenboden 33 und der Palettenbasis 41 erzeugt. Bei geeigneter Auswahl des Keilwinkels α zwischen einer Hochachse des Eingriffskörpers 51 und den Kontaktwänden 58 reicht bereits das Eigengewicht des Palettenbodens beziehungsweise allenfalls ein leichtes Nachpressen des Palettenbodens 33 aus, um einen mechanisch haltbaren Verbund zwischen der Palettenbasis 41 und dem Palettenboden 33 herzustellen, der einen Zusammenhalt der Komponenten der Kufenpalette 34 bei den nachfolgenden Montageschritten zur Herstellung des in Fig. 1 dargestellten Transport- und Lagerbehälters 20 ermöglicht.As if from a synopsis of FIGS. 6, 7 and 8 becomes clear, the engagement body 51 has a frusto-conical shape with elliptical cross section 57. In this case, the elliptical cross section 57 is oriented in the recess 52 of the Eckfußes 49, that the long ellipse axis b forms an intersection with a substantially planar in the region of the engaging body 51 contact surface 58 of the recess 52 and forms a substantially line-shaped contact region 59. Due to the frusto-conical shaped engaging body 51 and, as in particular in Fig. 8 can be seen, the wedge-shaped relative to each other opposite contact walls 58 of the recess 52 is generated by contact of the engaging body 51 against the contact walls 58 with increasing lowering of the engagement body 51 in the recess 52 a growing clamping force or holding force between the pallet base 33 and the pallet base 41. With a suitable selection of the wedge angle α between a vertical axis of the engaging body 51 and the contact walls 58, even the weight of the pallet base or at best a slight re-pressing of the pallet base 33 is sufficient to produce a mechanically durable bond between the pallet base 41 and the pallet base 33, the cohesion the components of the runner pallet 34 in the subsequent assembly steps for the preparation of in Fig. 1 shown transport and storage container 20 allows.

Damit kann die endgültige mechanische Verbindung zwischen der Palettenbasis 41 und dem Palettenboden 33 in einem gemeinsamen Montageschritt mit Herstellung der Verbindung zwischen der Kufenpalette 34 und dem Außenmantel 38 hergestellt werden. Hierzu werden dann die vorzugsweise als Schrauben 66 ausgebildeten Verbindungselemente nach Anordnung des Außenmantels 38 mit seinem Unterrand 65 auf dem Umfangsrand 67 des auf der Palettenbasis 41 angeordneten Palettenbodens 33 durch fluchtend miteinander angeordnete Befestigungsöffnungen 62, 63, 64, die im Unterrand 65 des Außenmantels 38, dem Umfangsrand 67 des Palettenbodens 33 und den Eckfüßen 49 der Palettenbasis 41 angeordnet sind, wie aus einer Zusammenschau der Fig. 1 und 3 deutlich wird, in die Eckfüße 49 eingeschraubt. Gleichzeitig mit der Verbindung des Außenmantel 38 mit der Kufenpalette 34 erfolgt also die endgültige mechanische Verbindung zwischen dem Palettenboden 33 und der Palettenbasis 41 der Kufenpalette 34.Thus, the final mechanical connection between the pallet base 41 and the pallet base 33 in a common assembly step with making the connection between the runner pallet 34 and the outer shell 38 can be made. For this purpose, then preferably designed as screws 66 connecting elements after arrangement of the outer sheath 38 with its lower edge 65 on the peripheral edge 67 of the pallet base 41 disposed on the pallet base 33 by aligned mounting holes 62, 63, 64, in the lower edge 65 of the outer shell 38, the peripheral edge 67 of the pallet base 33 and the corner feet 49 of the pallet base 41st are arranged, as from a synopsis of Fig. 1 and 3 becomes clear, screwed into the corner feet 49. Simultaneously with the connection of the outer shell 38 with the runners pallet 34 so the final mechanical connection between the pallet base 33 and the pallet base 41 of the runners pallet 34th

Wie aus einer Zusammenschau der Fig. 4 und 10 deutlich wird, ergibt sich aufgrund der Anordnung der Bodentraverse 42 auf der Stützfläche 53 der Kufenbrücke 43 eine nach unten abgeschirmte Aufnahme der Bodentraverse 42 in der Kufenpalette 34. Ferner zeigt Fig. 4 , dass die Ausnehmungen 52 in den Eckfüßen 49 mit Bodenwandungen 68 versehen sind, die eine Aufstandsfläche der Eckfüße 49 ausbilden.As if from a synopsis of Fig. 4 and 10 becomes clear, results due to the arrangement of the floor cross member 42 on the support surface 53 of the runner bridge 43 is a downwardly shielded recording of the floor cross member 42 in the runner pallet 34. Further shows Fig. 4 in that the recesses 52 in the corner feet 49 are provided with bottom walls 68 forming a footprint of the corner feet 49.

Ferner sind, wie insbesondere aus einer Zusammenschau der Fign. 4 und 9 hervorgeht, die Mittelfüße 44 und die Eckfüße 49 zwar mit einer übereinstimmenden Breite B ausgeführt. Allerdings weisen die Eckfüße 49 im Vergleich zu den Mittelfüßen 44, die eine Länge L1 aufweisen, eine größere Länge L2 auf.Furthermore, as in particular from a synopsis of FIGS. 4 and 9 shows that the middle feet 44 and the corner feet 49, although executed with a matching width B. However, the corner feet 49 have a greater length L2 compared to the center feet 44, which have a length L1.

Weiterhin zeigt insbesondere eine Zusammenschau der Fig. 3 und 11 , dass die Kufenbasis 45 der Mittelkufe 35 eine geringere Höhe h aufweist, als die Kufenbasis 45 der Außenkufen 36 und 37, so dass bei Belastung des Palettenbodens 33 mit einem mit Flüssigkeit gefüllten Innenbehälter 21 trotz der maximalen Durchbiegung des Behälterbodens 33 zwischen dem Mittelfuß 44 der Mittelkufe 35 und den Außenfüßen 46, 47 der Mittelkufe 35 eine immer noch ausreichende lichte Höhe zwischen der Unterseite 50 des Palettenbodens 33 und der Kufenbasis 44 gegeben ist, um ein kollisionsfreies Unterfahren des Palettenbodens mit einer Hubstaplereinrichtung zu ermöglichen.Furthermore, shows in particular a synopsis of Fig. 3 and 11 in that the runner base 45 of the center runner 35 has a lower height h than the runner base 45 of the outer runners 36 and 37, so that when the pallet base 33 is loaded with a liquid-filled inner container 21 in spite of the maximum deflection of the container bottom 33 between the middle foot 44 Center skid 35 and the outer feet 46, 47 of the center skid 35 is still given a sufficient clearance between the bottom 50 of the pallet base 33 and the skid base 44 to allow a collision-free driving under the pallet bottom with a Hubstaplereinrichtung.

Wie in den Fig. 12 und 13 dargestellt, weist der Palettenboden 33 zur Erzielung einer möglichst großen Eigensteifigkeit bei geringst möglichem Materialeinsatz eine Struktur auf, die in einem Mittelabschnitt 70 Längssicken 71 und in Randabschnitten 72, 73, die bei Anordnung eines Innenbehälters 21 auf dem Palettenboden 33 parallel zu der Frontwand 22 beziehungsweise der Rückwand 23 des Innenbehälters 21 ( Fig. 1 ) verlaufen, Quersicken 74 auf. Wie die Fig. 12 und 13 ferner zeigen, sind die Quersicken 74 sowohl auf einer Oberseite 75 des Palettenbodens 33 als auch auf der Unterseite 50 des Palettenbodens 33 mit Zwischenstegen 76 gegeneinander versteift. Die Längssicken 71 sind im Bereich einer zentralen Traversenaufnahme 77, die auf der Unterseite 50 zur Anordnung der in den Fig. 3 und 14 dargestellten Bodentraverse 42 dient, mit einem die Höhe des Palettenbodens 33 reduzierenden Rücksprungbereich versehen.As in the FIGS. 12 and 13 shown, the pallet base 33 in order to achieve the greatest possible inherent rigidity with the least possible use of material on a structure which in a central portion 70 longitudinal beads 71 and in edge portions 72, 73 which in arrangement of a Inner container 21 on the pallet base 33 parallel to the front wall 22 and the rear wall 23 of the inner container 21 ( FIGS. Fig. 1 ), transverse beads 74 on. As the FIGS. 12 and 13 further show, the transverse beads 74 are stiffened against each other both on an upper side 75 of the pallet base 33 and on the underside 50 of the pallet base 33 with intermediate webs 76. The longitudinal corrugations 71 are in the region of a central truss receptacle 77, which on the bottom 50 for the arrangement of the in the Fig. 3 and 14 shown bottom cross member 42 is provided with a height of the pallet base 33 reducing return area.

Wie Fig. 14 zeigt, ist im Vergleich zur Höhe der Längssicken 71 im Mittelabschnitt 70 die Höhe der Quersicken 74 in den Randabschnitten 72, 73 größer ausgebildet, derart, dass sich eine Unterseite 78 der auf ihrer Stützfläche 53 die Bodentraverse 42 aufnehmenden Kufenbrücke 43 in einer gemeinsamen Horizontalebene mit Unterseiten 79 der Quersicken 74 befindet. Durch Ausbildung eines Überstands 80 der Unterseiten 79 der Quersicken 74 gegenüber Unterseiten 81 der Längssicken 71 wird ein Aufnahmeraum für die Bodentraverse 42 geschaffen.As Fig. 14 shows, in comparison to the height of the longitudinal corrugations 71 in the middle section 70, the height of the transverse corrugations 74 in the edge portions 72, 73 formed larger, such that a bottom 78 of the support surface 53, the bottom cross-piece 42 receiving runner bridge 43 in a common horizontal plane Bottoms 79 of the transverse beads 74 is located. By forming a supernatant 80 of the lower sides 79 of the transverse corrugations 74 opposite lower sides 81 of the longitudinal corrugations 71, a receiving space for the floor cross member 42 is created.
