Definitions
- the present invention relates to a stackable pallet, in particular for heavy loads, with a rectangular upper frame in plan, four corner posts and a patette base, which also has two lower stiffening struts connecting two corner posts in pairs.
- a palette is known, for example, from German published patent application DE-A-3 342 345.
- a known pallet of this type can be used on the one hand as a shelf module by placing several pallets on top of one another for this purpose. On the other hand, it is also possible to stack several pallets compactly one inside the other for better use of product and storage rooms when not in use. The stacking is u. a.
- the two rear corner posts are narrower than the two front corner posts, so that the rear corner posts have space between the side struts of the upper frame of another pallet when stacked together.
- struts are proposed in the known pallet which divide the surfaces of the side parts in the vertical position and can be folded down into a horizontal position. Folding down is absolutely necessary, otherwise the pallets would no longer be stackable.
- the known pallets Before the known pallets can be stacked one inside the other, it is necessary to loosen the locking pins that lock the struts in the vertical position and to fold the struts into the horizontal position, which is time-consuming when stacking a large number of pallets.
- the known range is also completely open towards the front, so that the load is not prevented from falling out.
- a further pallet has become known from French patent specification FR-A-1 475 070, of which several pallets can be placed on top of one another and several pallets can be stacked compactly one inside the other.
- the type of pallet proposed there only has walls on the two transverse sides to limit the storage space and is open on the other sides. There is therefore a risk of the cargo falling or rolling out even with this known pallet.
- the object of the present invention is to provide a type of pallet which allows both stacking on top of one another and compact stacking of several pallets without changes to the pallet, such as disassembly of individual parts, and in which the storage space for the load is largely limited on all sides so that even smaller loads are prevented from falling out.
- a pallet according to the invention is suitable for storing and transporting any goods.
- the pallet is intended to be used to transport heavy loads, for example frozen meat or other frozen foods.
- the goods are usually transported by truck on pallets. It is advantageous if the pallets have a standardized euro size of 120 cm in length and 100 cm in width, so that transportation by truck of any nationality is possible.
- the pallet has an all-round upper horizontal frame made up of two longitudinal frame tubes and two transverse frame tubes. However, only the longitudinal frame tubes lie on two corner posts, while the frame cross tubes lie outside the rectangle formed by the corner posts. This enables the corner posts of the next higher pallet to fit between the cross frame tubes of the lower pallet when the pallets are stacked compactly one inside the other.
- the outer distance between two corner posts is a small tolerance less than the distance between the opposite inner edges of the frame cross tubes, so that the pallets can be effortlessly inserted into one another without the risk of jamming.
- the trough-like receiving body for the cargo has an approximately U-shaped cross-section and is also dimensioned such that its maximum extension in the longitudinal direction of the pallet on each side is less than the distance between the inner edges of the frame cross tubes so that it fits between them.
- the receptacle body consists of two or more parallel U-shaped tubes which are arranged at a distance from one another. If smaller loads are to be picked up, a larger number of these U-tubes are arranged closer together. It is essential that the U-tubes are only connected to the top of the frame cross tubes so that this connection does not hinder the interlocking of the pallets.
- the receptacle body consists of a one-piece sheet metal tub with side walls which are slightly conical towards the tub bottom.
- the taper is required so that when the pallets are stacked one inside the other, the trays easily fit into one another.
- the sheet metal tray in turn only has a connection at the top to the frame cross tubes. It is also essential in both embodiments that there is sufficient space on the longitudinal sides between the receiving body and the frame longitudinal tubes, which takes up the corner posts of the upper pallets when the pallets are stacked one inside the other and is therefore preferably a multiple of the width of a corner post. The width of this space determines how many pallets can be stacked compactly.
- U-shaped tubular brackets are placed in reverse on the cross frame tubes, so that there is a rectangular space between these tubular brackets and the underlying cross frame tubes.
- This rectangular opening facilitates the removal of a pallet from a stack of several pallets stacked one inside the other with the forklift, which can reach into this opening. If several pallets stacked one inside the other are to be transported together, the forklift can reach under a lower stiffening strut of the bottom pallet, which connects two corner posts of a pallet in pairs, and lift the pallets together; in this case, the pallets are moved from the long side.
- the pallet consists of an upper rectangular frame which is closed on all sides and consists of two longitudinal frame tubes 2a, 2b and two transverse frame tubes 6a, 6b.
- This upper rectangular frame preferably has the EuroNorm dimensions 120 cm x 100 cm, but can also have any other dimension and, for example, also be square.
- the longitudinal frame tubes lie on the corner posts 1a, 1b. 1 c. 1d of the pallet, which preferably have a rectangular cross section like the frame tubes.
- the four corner posts are arranged so that they form a rectangle in plan view, the length dimension - measured from the outer edge to the outer edge of two corner posts 1a, 1b - is designated by X.
- the frame cross tubes 6a, 6b lie outside this rectangle spanned by the corner posts.
- the distance between the inner edges of the frame cross tubes 6a, 6b, which is denoted by Y, must be larger on each side by the tolerance dimension ⁇ 1 , i.e. a total of 2 x A, than the length dimension X, so that when cornering the corner posts of the next higher pallet between the Frame cross tubes of the underlying have enough space and tilting when stacking one another is prevented by means of a forklift.
- the receiving body for the cargo is formed from a plurality of parallel tubes 7 which are U-shaped in side view, the horizontal sections 8 of which form the pallet base and whose vertical sections 7a, 7b have spacers 9 at the upper leg ends, which are connected to the frame cross tubes 6a, 6b.
- the receiving body has no connection to the pallet frame or to the corner posts, since this would be a hindrance when the pallets are compactly stacked one inside the other.
- the outer distance of the vertical legs 7a, 7b, which is designated by Z, is due to the spacers 9 at the upper leg ends on each side by a tolerance dimension A 2 less than the distance Y of the inner edges of the frame cross tubes 6a, 6b, so that the receiving body of the upper pallet also has enough space when stacked compactly between the frame cross tubes of the lower pallet.
- an intermediate space 41 must remain on both sides, the width of which corresponds to the tube width of a corner post 1a or better a multiple of the width of a corner post, since in the case of compact stacking the pallets of the corner posts of one or more upper pallets is received by this space 41 of the lower pallets.
- FIG. 6 shows three pallets stacked one inside the other from the short side.
- the middle pallet is advantageously offset from the lower pallet to the right by about a corner post width.
- the upper pallet is offset from the lower one by a corner post width to the left.
- the right corner posts of the pallets are designated in Fig. 6 with 11a, 21a, 31 a.
- the vertical limbs of the left outer U-tubes of the receiving body of the pallets are designated 17a, 27a, 37a in the illustration.
- the space between the corner posts and the outer U-tube is so wide that three pallets can be stacked one inside the other.
- next higher pallet must be placed on the upper pallet when stacking.
- the space between the corner post and the outer U-tube is chosen wider, which is easily possible, for example, for the transport of larger loads.
- the width of the corner posts and U-tubes can also be reduced if goods of lower weight are to be transported with the pallet.
- la, 1b and 1c, 1d are each connected in pairs by lower stiffening struts 3a, 3b parallel to the upper longitudinal frame tubes, which prevent the corner posts from spreading apart when the pallet is loaded.
- no connection is provided on the transverse side of the pallet, between the corner posts 1b, 1, since this would be a hindrance when the pallets were stacked one inside the other.
- U-shaped pipe brackets 6c, 6d are placed on the frame cross tubes 6a, 6b, which together with the frame cross tubes form a rectangular frame with a rectangular opening 6e. The forklift can reach into this rectangular opening 6e when the pallet is to be lifted.
- FIG. 5 shows a view of three pallets stacked one inside the other from the long side of the pallet.
- 13a, 23a, 33a denote the lower stiffening struts, 12a, 22a, 32a the longitudinal frame tubes and 31a, 31b the two front corner posts of the uppermost pallet, 11a, 11b the two front corner posts of the lower pallet.
- FIG. 7 shows two pallets placed one on top of the other in a view from the long side of the pallet. It can be seen that the corner posts 21 a, 21 b of the upper pallet are on the corner posts 11a, 11b of the lower pallet. So that the pallets stand securely on one another, cylindrical cams 4 are arranged on the corner posts and correspondingly large cylindrical recesses 5 are provided in the feet of the corner posts, which receive the cams of the respective lower pallet. In order to stabilize the corner connection between corner posts 21a, 21b. And longitudinal frame tube 22a, angle plates 38 are provided there.
- FIGS. 8 and 9 show an alternative embodiment of the pallet according to the invention, in which the receiving body for the cargo consists of a one-piece sheet metal trough 40 with an essentially U-shaped cross section.
- the side walls 42 of the sheet metal trough 40 run slightly conically towards the pallet base 43. Since the largest dimension of the receiving body in the longitudinal direction of the pallet Z must in turn be less than the distance between the inner edges of the frame cross tubes Y, horizontal spacers 44 are provided which connect the side walls 42 of the sheet metal trough to the frame cross tubes 6a, 6b.
- the number of pallets that can be stacked one inside the other is determined by the width of the intermediate space 41 between the outer edge 45 of the sheet metal trough and the longitudinal frame tube and also by the tube width of the corner post.
- further vertical intermediate struts 14 can be provided on the long sides of the pallet for connecting the longitudinal frame tubes 2a, 2b to the lower stiffening struts 3a, 3b.
- the compact stacking of the pallets is made possible by this intermediate strive 14 not disabled.
- the area between the longitudinal frame tube 2a and the stiffening strut 3a on the long side of the pallet can even be completely closed, for example by a sheet metal, which has the advantage that the load is prevented from falling out on the long sides of the pallet.

Abstract
Description
Die vorliegende Erfindung betrifft eine stapelbare Palette insbesondere für schwere Lasten mit im Grundriß rechteckigem oberen Rahmen, vier Eckpfosten und einem Patettenboden, die außerdem zwei untere, jeweils zwei Eckpfosten paarweise verbindende Versteifungsstreben aufweist. Beispielsweise aus der deutschen Offenlegungsschrift DE-A-3 342 345 ist eine derartige Palette bekannt. Eine bekannte derartige Palette kann einerseits als Regalbaustein verwendet werden, indem zu diesem Zweck mehrere Paletten aufeinander gestellt werden. Es ist andererseits auch möglich zur besseren Nutzung von Produktios-und Lagerräumen bei Nichtgebrauch mehrere Paletten kompakt ineinander zu stapeln. Das ineinander stapeln wird u. a. dadurch möglich, daß die beiden hinteren Eckpfosten enger stehen als die beiden vorderen Eckpfosten, so daß die hinteren Eckpfosten zwischen den Seitenstreben des oberen Rahmens einer anderen Palette beim ineinander stapeln Platz haben. Um wegen der offenen Rahmenstruktur ein Herausfallen kleinerer Ladegüter an den Seitenteilen der Palette zu vermeiden, werden bei der bekannten Palette Streben vorgeschlagen, die in der vertikalen Position die Flächen der Seitenteile unterteilen und in eine horizontale Position umklappbar sind. Das Umklappen ist unbedingt erforderlich, da sonst die Paletten nicht mehr ineinander stapelbar wären. Bevor die bekannten Paletten ineinander gestapelt werden können, ist es daher notwendig, die Arretierstifte, die die Streben in der vertikalen Lage arretieren, zu lösen und die Streben in die horizontale Lage umzuklappen, was beim ineinander stapeln einer größeren Anzahl von Paletten zeitraubend ist. Die bekannte Palette ist außerdem nach der Frontseite hin völlig offen, so daß dort ein Herausfallen des Ladegutes nicht verhindert wird.The present invention relates to a stackable pallet, in particular for heavy loads, with a rectangular upper frame in plan, four corner posts and a patette base, which also has two lower stiffening struts connecting two corner posts in pairs. Such a palette is known, for example, from German published patent application DE-A-3 342 345. A known pallet of this type can be used on the one hand as a shelf module by placing several pallets on top of one another for this purpose. On the other hand, it is also possible to stack several pallets compactly one inside the other for better use of product and storage rooms when not in use. The stacking is u. a. possible that the two rear corner posts are narrower than the two front corner posts, so that the rear corner posts have space between the side struts of the upper frame of another pallet when stacked together. In order to prevent smaller loads from falling out on the side parts of the pallet because of the open frame structure, struts are proposed in the known pallet which divide the surfaces of the side parts in the vertical position and can be folded down into a horizontal position. Folding down is absolutely necessary, otherwise the pallets would no longer be stackable. Before the known pallets can be stacked one inside the other, it is necessary to loosen the locking pins that lock the struts in the vertical position and to fold the struts into the horizontal position, which is time-consuming when stacking a large number of pallets. The known range is also completely open towards the front, so that the load is not prevented from falling out.
Aus der französischen Patentschrift FR-A-1 475 070 ist eine weitere Palette bekanntgeworden, von der sowohl mehrere Paletten aufeinander gestellt werden als auch mehrere Paletten kompakt ineinander gestapelt werden können. Der dort vorgeschlagene Palettentyp weist jedoch nur an den beiden Querseiten Wände zur Begrenzung des Stauraums auf und ist zu den anderen Seiten hin offen. Die Gefahr des Herausfallens oder Herausrollens des Ladeguts besteht daher auch bei dieser bekannten Palette.A further pallet has become known from French patent specification FR-A-1 475 070, of which several pallets can be placed on top of one another and several pallets can be stacked compactly one inside the other. However, the type of pallet proposed there only has walls on the two transverse sides to limit the storage space and is open on the other sides. There is therefore a risk of the cargo falling or rolling out even with this known pallet.
Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, einen Palettentyp zu schaffen, der sowohl ein aufeinanderstellen als auch ein kompaktes ineinander stapelnmehrerer Paletten zuläßt, ohne daß dazu an der Palette Veränderungen wie Demontage einzelner Teile vorgenommen werden müssen, und bei dem der Stauraum für das Ladegut weitgehend nach allen Seiten hin so begrenzt ist, daß das Herausfallen auch kleinerer Ladegüter verhindert wird.In contrast, the object of the present invention is to provide a type of pallet which allows both stacking on top of one another and compact stacking of several pallets without changes to the pallet, such as disassembly of individual parts, and in which the storage space for the load is largely limited on all sides so that even smaller loads are prevented from falling out.
Die Lösung dieser Aufgabe liefert eine Palette mit den Merkmalen des Anspruchs 1. Im Anspruch 1 kommt dabei ein allgemeinerer Lösungsgedanke zum Ausdruck, wohingegen insbesondere in den Ansprüchen 2 und 8 konkretere Ausführungsformen der Aufgabenlösung ausgeführt sind. Die übrigen Unteransprüche haben weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Palette zum Inhalt.The solution to this problem is provided by a palette with the features of
Im prinzip ist eine erfindungsgemäße Palette zur Lagerung und zum Transport beliebiger Güter geeignet. Insbesondere soll die Palette dem Transport schwerer Lasten, nämlich beispielsweise von Tiefkühlfleisch oder anderen tiefgefrorenen Lebensmitteln dienen. In diesem Fall ist es zweckmäßig, die Palette aus Edelstahl herzustellen. Der Transport der genannten Güter mittels der Paletten geschieht in der Regel in Lastkraftwagen. Dabei ist es von Vorteil, wenn die Paletten ein genormtes Euro-Maß von 120 cm Länge und 100 cm Breite aufweisen, damit der Transport mit Lastkraftwagen beliebiger Nationalität möglich ist.In principle, a pallet according to the invention is suitable for storing and transporting any goods. In particular, the pallet is intended to be used to transport heavy loads, for example frozen meat or other frozen foods. In this case it is advisable to make the pallet from stainless steel. The goods are usually transported by truck on pallets. It is advantageous if the pallets have a standardized euro size of 120 cm in length and 100 cm in width, so that transportation by truck of any nationality is possible.
Beim Transport im Lastkraftwagen können mehrere Paletten aufeinander gestellt werden, in der Weise, daß jeweils die Eckpfosten der oberen Palette auf den Eckpfosten der unteren Palette ruhen, so daß die Gewichtskräfte hauptsächlich in die Eckpfosten eingeleitet werden. An den Paletten sind Verbindungselemente vorgesehen, durch die sie in dieser Stapelstellung fixiert werden. Beim Transport von beispielsweise Tiefkühlfleisch sind an die Belastbarkeit der Paletten wegen der hohen Ladegewichte hohe Ansprüche zu stellen, denen die erfindungsgemäße Palette bei Ausführung in Edelstahl durch ihre Konstruktionsweise gerecht wird. Wird beispielsweise eine Palette mit jeweils 200 kg Gewicht beladen, muß bei drei übereinander gestapelten Paletten die untere ein Gewicht von mehr als 600 kg aufnehmen. Auch kommt es beim Umgang mit den beladenen Paletten, etwa beim Be- und Entladen eines Lastkraftwagens- mit den Paletten mittels eines Gabelstaplers vor, daß mit den Paletten nicht sehr sorgfältig umgegangen wird, beispielsweise die Paletten in einer gewünschten Position vom Gabelstapler aus einigen cm Höhe einfach fallengelassen werden. Hieraus ergeben sich Mindestanforderungen an die Bauweise des Palettenrahmens und des Aufnahmekörpers für das Ladegut hinsichtlich der Anzahl der zu verwendenden Rohre und der erforderlichen Materialstärke. Andererseits soll wegen der hohen Materialkosten bei der Ausführung in Edelstahl eine Palette von maximaler Belastbarkeit unter Verwendung von möglichst wenig Material geschaffen werden. Auch diesem Gesichtspunkt trägt die erfindungsgemäß konstruierte Palette Rechnung. Unter Berücksichtigung der vorgenannten Aspekte wird die eingangs genannte Aufgabenstellung wie folgt gelöst. Die Palette hat einen allseitig geschlossenen oberen horizontalen Rahmen aus zwei Rahmenlängsrohren und zwei Rahmenquerrohren. Jedoch liegen nur die Rahmenlängsrohre auf jeweils zwei Eckpfosten auf, während die Rahmenquerrohre ausserhalb des von den Eckpfosten gebildeten Rechtecks liegen. Dadurch wird ermöglicht, daß beim kompakten ineinander stapeln der Paletten die Eckpfosten der nächsth.ö- heren Palette zwischen die Rahmenquerrohre der tieferen Palette passen. Der äussere Abstand zweier Eckpfosten ist dabei um ein geringes Toleranzmaß geringer als der Abstand der gegenüberliegenden Innenkanten der Rahmenquerrohre, damit ein müheloses ineinandersetzen der Paletten ohne die Gefahr des Verkantens möglich ist.When transported in a truck, several pallets can be placed on top of one another in such a way that the corner posts of the upper pallet rest on the corner posts of the lower pallet, so that the weight forces are mainly introduced into the corner posts. Connecting elements are provided on the pallets, by means of which they are fixed in this stacking position. When transporting frozen meat, for example, the load-bearing capacity of the pallets is subject to high demands due to the high loading weights, which the pallet according to the invention meets when it is made of stainless steel due to its design. If, for example, a pallet with a weight of 200 kg is loaded, the lower pallet with three pallets stacked one on top of the other must carry a weight of more than 600 kg. It also happens when handling the loaded pallets, for example when loading and unloading a truck with the pallets by means of a forklift, that the pallets are not handled very carefully, for example the pallets in a desired position by the forklift from a height of a few cm just be dropped. This results in minimum requirements for the construction of the pallet frame and the receiving body for the cargo with regard to the number of pipes to be used and the required material thickness. On the other hand, because of the high material costs for the execution in stainless steel, a range of maximum resilience should be created using as little material as possible. The pallet constructed according to the invention also takes this aspect into account. Taking the aforementioned aspects into account, the task mentioned at the beginning is solved as follows. The pallet has an all-round upper horizontal frame made up of two longitudinal frame tubes and two transverse frame tubes. However, only the longitudinal frame tubes lie on two corner posts, while the frame cross tubes lie outside the rectangle formed by the corner posts. This enables the corner posts of the next higher pallet to fit between the cross frame tubes of the lower pallet when the pallets are stacked compactly one inside the other. The outer distance between two corner posts is a small tolerance less than the distance between the opposite inner edges of the frame cross tubes, so that the pallets can be effortlessly inserted into one another without the risk of jamming.
Der wannenartige Aufnahmekörper für das Ladegut hat etwa U-förmigen Querschnitt und ist ebenfalls so bemessen, daß seine maximale Ausdehnung in Palettenlängsrichtung an jeder Seite um ein Toieranzmaß geringer ist als der Abstand der Innenkanten der Rahmenquerrohre, damit er zwischen diese hindurch passt. Für den Aufnahmekörper werden zwei konkrete Ausführungsformen beispielhaft vorgeschlagen. Bei der einen besteht der Aufnahmekörper aus zwei oder mehreren im Abstand voneinander angeordneten parallelen in Seitenansicht U-förmigen Rohren. Sollen kleinere Ladegüter aufgenommen werden, wird eine größere Anzahl dieser U-Rohre in engerem Abstand angeordnet. Wesentlich ist, daß die U-Rohre nur oben mit den Rahmenquerrohren verbunden sind, damit diese Verbindung nicht das ineinanderstellen der Paletten behindert. Bei der anderen Ausführungsform besteht der Aufnahmekörper aus einer einstückigen Blechwanne mit zum Wannenboden hin schwach konisch verlaufenden Seitenwänden. Die Konizität ist erforderlich, damit beim ineinander stapeln der Paletten die Wannen problemlos ineinanderpassen. Die Blechwanne hat wiederum nur oben eine Verbindung nur zu den Rahmenquerrohren. Wesentlich ist ausserdem bei beiden Ausführungsformen, daß an den Längsseiten zwischen dem Aufnahmekörper und den Rahmen!ängsrohren ein ausreichender Zwischenraum verbleibt, der beim ineinander stapeln der Paletten die Eckpfosten der oberen Paletten aufnimmt und daher vorzugsweise ein Vielfaches der Breite eines Eckpfostens breit ist. Die Breite dieses Zwischenraums bestimmt wieviele Paletten kompakt ineinander gestapelt werden können.The trough-like receiving body for the cargo has an approximately U-shaped cross-section and is also dimensioned such that its maximum extension in the longitudinal direction of the pallet on each side is less than the distance between the inner edges of the frame cross tubes so that it fits between them. Two specific embodiments are proposed as examples for the receiving body. In one, the receptacle body consists of two or more parallel U-shaped tubes which are arranged at a distance from one another. If smaller loads are to be picked up, a larger number of these U-tubes are arranged closer together. It is essential that the U-tubes are only connected to the top of the frame cross tubes so that this connection does not hinder the interlocking of the pallets. In the other embodiment, the receptacle body consists of a one-piece sheet metal tub with side walls which are slightly conical towards the tub bottom. The taper is required so that when the pallets are stacked one inside the other, the trays easily fit into one another. The sheet metal tray in turn only has a connection at the top to the frame cross tubes. It is also essential in both embodiments that there is sufficient space on the longitudinal sides between the receiving body and the frame longitudinal tubes, which takes up the corner posts of the upper pallets when the pallets are stacked one inside the other and is therefore preferably a multiple of the width of a corner post. The width of this space determines how many pallets can be stacked compactly.
Nach einer bevorzugten Ausführungsform der Erfindung sind auf die Rahmenquerrohre jeweils umgekehrt U-förmige Rohrbügel aufgesetzt, so daß sich zwischen diesen Rohrbügeln und den darunter liegenden Rahmenquerrohren ein rechteckiger Zwischenraum ergibt. Diese rechteckige Öffnung erleichtert das Herausnehmen einer Palette aus einem Stapel mehrerer ineinander gestapelter Paletten mit dem Gabelstapler, der in diese Öffnung hineingreifen kann. Wenn mehrere ineinander gestapelte Paletten gemeinsam transportiert werden sollen, kann der Gabelstapler unter eine untere, jeweils zwei Eckpfosten einer Palette paarweise verbindende Versteifungsstrebe der untersten Palette greifen und die Paletten gemeinsam anheben, in diesem Fall werden die Paletten vcn der Längsseite her angefahren. Das Anfahren und Herausnehmen einer einzelnen Palette oder Anheben mehrerer Paletten kann auch von der Querseite her erfolgen, wobei der Gabelstapler in die entsprechende rechteckige Öffnung über dem Rahmenquerrohr greift. Es ist daher unerheblich, ob die Palettenstapel bei der Lagerung in Längsrichtung oder in Querrichtung hintereinander angeordnet werden.According to a preferred embodiment of the invention, U-shaped tubular brackets are placed in reverse on the cross frame tubes, so that there is a rectangular space between these tubular brackets and the underlying cross frame tubes. This rectangular opening facilitates the removal of a pallet from a stack of several pallets stacked one inside the other with the forklift, which can reach into this opening. If several pallets stacked one inside the other are to be transported together, the forklift can reach under a lower stiffening strut of the bottom pallet, which connects two corner posts of a pallet in pairs, and lift the pallets together; in this case, the pallets are moved from the long side. Starting and removing a single pallet or lifting several pallets can also be done from the transverse side, with the forklift reaching into the corresponding rectangular opening above the frame cross tube. It is therefore irrelevant whether the pallet stacks are arranged one behind the other during storage in the longitudinal direction or in the transverse direction.
Im Folgenden werden die erfindungsgemäßen Paletten in Ausführungsbeispielen anhand der Zeichnungen näher beschrieben.In the following, the pallets according to the invention are described in more detail in exemplary embodiments with reference to the drawings.

Zunächst wird eine Ausführungsform der erfindungsgemäßen Palette anhand der Fig. 1-7 beschrieben. Die Palette besteht aus einem allseitig geschlossenen oberen rechteckigen Rahmen aus zwei Rahmenlängsrohren 2a, 2b und zwei Rahmenquerrohren 6a, 6b. Dieser obere rechteckige Rahmen weist in bevorzugter Weise die EuroNorm-Masse 120 cm x 100 cm auf, kann aber auch jedes andere Maß haben und beispielsweise auch quadratisch sein. Die Rahmenlängsrohre liegen auf den Eckpfosten 1a, 1b. 1 c. 1d der Palette auf, die in bevorzugter Weise wie die Rahmenrohre rechteckigen Querschnitt haben. Die vier Eckpfosten sind so angeordnet, daß sie in der Draufsicht ein Rechteck bilden, dessen Längenmaß - gemessen von Aussenkante zu Aussenkante zweier Eckpfosten 1a, 1b - mit X bezeichnet ist. Die Rahmenquerrohre 6a, 6b liegen ausserhalb dieses von den Eckpfosten aufgespannten Rechtecks. Der Abstand der Innenkanten der Rahmenquerrohre 6a, 6b der mit Y bezeichnet ist, muß an jeder Seite jeweils um das Toleranzmaß Δ1, also insgesamt um 2 x A, größer sein als das Längenmaß X, damit beim ineinanderstellen die Eckpfosten der nächsthöheren Palette zwischen den Rahmenquerrohren der darunterliegenden ausreichend Platz haben und ein Verkanten beim ineinander stapeln mittels eines Gabelstaplers verhindert wird.First, an embodiment of the pallet according to the invention is described with reference to FIGS. 1-7. The pallet consists of an upper rectangular frame which is closed on all sides and consists of two
Bei der in den Figuren 1-7 dargestellten Ausführungsform der Palette ist der Aufnahmekörper für das Ladegut aus mehreren parallelen, in Seitenansicht U-förmigen Rohren 7 gebildet, deren horizontale Abschnitte 8 den Palettenboden bilden und deren vertikale Abschnitte 7a, 7b an den oberen Schenkelenden Distanzstücke 9 aufweisen, die mit den Rahmenquerrohren 6a, 6b verbunden sind. Der Aufnahmekörper hat darüberhinaus keine Verbindung zum Palettenrahmen oder zu den Eckpfosten, da diese beim kompakten ineinander stapeln der Paletten hinderlich wäre. Der äussere Abstand der vertikalen Schenkel 7a, 7b, der mit Z bezeichnet ist, ist aufgrund der Distanzstücke 9.an den oberen Schenkelenden an jeder Seite jeweils um ein Toleranzmaß A2 geringer als der Abstand Y der Innenkanten der Rahmenquerrohre 6a, 6b, so daß auch der Aufnahmekörper der oberen Palette beim kompakten ineinander stapeln zwischen den Rahmenquerrohren der unteren Palette ausreichend Platz hat. Zwischen dem äussersten U-Rohr 7 des Aufnahmekörpers und dem jeweiligen Rahmenlängsrohr 2a, 2b der Palette muß an beiden Seiten ein Zwischenraum 41 bleiben, dessen Breite der Rohrbreite eines Eckpfostens 1a bzw. besser einem Vielfachen der Breite eines Eckpfostens entspricht, da beim kompakten ineinander stapeln der Paletten der Eckpfosten einer oder mehrerer oberer Paletten von diesem Zwischenraum 41 der unteren Paletten aufgenommen wird.In the embodiment of the pallet shown in FIGS. 1-7, the receiving body for the cargo is formed from a plurality of
Aus Figur 6 ist ersichtlich, wie die Paletten beim kompakten ineinander stapeln im Falle des Nichtgebrauchs ineinander verschachtelt werden. Diese Ansicht zeigt drei ineinander gestapelte Paletten von der Querseite. Die mittlere Palette ist dabei in vorteilhafter Weise gegenüber der unteren Palette nach rechts versetzt um etwa eine Eckpfostenbreite. Die obere Palette ist gegenüber der unteren um eine Eckpfostenbreite nach links versetzt angeordnet. Die rechten Eckpfosten der Paletten sind in Fig. 6 mit 11a, 21a, 31 a bezeichnet. Die vertikalen Schenkel der linken äusseren U-Rohre des Aufnahmekörpers der Paletten sind in der Darstellung mit 17a, 27a, 37a bezeichnet. In dem Beispiel ist der Zwischenraum zwischen Eckpfosten und dem äusseren U-Rohr so breit daß drei Paletten ineinander gestapelt werden können. Die nächsthöhere Palette muß beim Stapeln auf die obere Palette gestellt werden. Es ist jedoch möglich mehr als drei Paletten ineinander zu stapeln, wenn der Zwischenraum zwischen Eckpfosten und äusserem U-Rohr breiter gewählt wird, was beispielsweise für den Transport grösserer Ladegüter ohne weiteres möglich ist. Auch kann die Breite der Eckpfosten und der U-Rohre verringert werden, wenn Ladegüter von geringerem Gewicht mit der Palette transportiert werden sollen.It can be seen from FIG. 6 how the pallets are nested into one another when compactly stacked when not in use. This view shows three pallets stacked one inside the other from the short side. The middle pallet is advantageously offset from the lower pallet to the right by about a corner post width. The upper pallet is offset from the lower one by a corner post width to the left. The right corner posts of the pallets are designated in Fig. 6 with 11a, 21a, 31 a. The vertical limbs of the left outer U-tubes of the receiving body of the pallets are designated 17a, 27a, 37a in the illustration. In the example, the space between the corner posts and the outer U-tube is so wide that three pallets can be stacked one inside the other. The next higher pallet must be placed on the upper pallet when stacking. However, it is possible to stack more than three pallets into one another if the space between the corner post and the outer U-tube is chosen wider, which is easily possible, for example, for the transport of larger loads. The width of the corner posts and U-tubes can also be reduced if goods of lower weight are to be transported with the pallet.
Wie aus Figur 2 ersichtlich ist, sind la, 1b und 1c, 1d jeweils paarweise durch untere, zu den oberen Rahmenlängsrohren parallele Versteifungsstreben 3a, 3b verbunden, die ein auseinanderspreizen der Eckpfosten bei Belastung der Palette verhindern. An der Querseite der Palette, zwischen den Eckpfosten 1b, 1 ist dagegen keine Verbindung vorgesehen, da diese beim ineinander stapeln der Paletten hinderlich wäre. Auf die Rahmenquerrohre 6a, 6b sind umgekehrt U-förmige Rohrbügel 6c, 6d aufgesetzt, die zusammen mit den Rahmenquerrohren einen rechteckigen Rahmen bilden mit einer rechteckigen Öffnung 6e. In diese rechteckige Öffnung 6e kann der Gabelstapler hineinfassen, wenn die Palette angehoben werden soll. Beim Anheben der Palette von der Längsseite her kann der Gabelstapler unter die Versteifungsstrebe 3a greifen. Durch hineinfassen in die rechteckige Öffnung 6e (Fig. 6) kann der Gabelstapler auch eine einzelne Palette aus einem Stapel herausheben. Durch Untergreifen des Rahmenlängsrohres 12a der unteren Palette (Fig. 5) kann der Gabelstapler mehrere Paletten, die ineinander gestapelt sind, gleichzeitig anheben. In Figur 5 ist eine Ansicht dreier ineinander gestapelter Paletten von der Paletten-Längsseite her dargestellt. Mit 13a, 23a, 33a sind die unteren Versteifungsstreben, mit 12a, 22a, 32a die Rahmenlängsrohre und mit 31a, 31 b die beiden vorderen Eckpfosten der obersten Palette bezeichnet, mit 11a, 11b die beiden vorderen Eckpfosten der unteren Palette. Die Höhendifferenz 39 zweier Paletten ergibt sich daraus, daß die Rahmenquerrohre 6a, 6b einer oberen Palette beim ineinander stapeln auf den Rohrbügeln 6c, 6d der darunterliegenden Palette aufliegen. In Figur 7 sind zwei aufeinander gestellte Paletten in einer Ansicht von der Paletten-Längsseite her dargestellt. Daraus ist ersichtlich, daß die Eckpfosten 21 a, 21 b der oberen Palette auf den Eckpfosten 11a, 11b der unteren Palette stehen. Damit die Paletten sicher aufeinander stehen, sind auf den Eckpfosten zylindrische Nocken 4 angeordnet und unten in den Füßen der Eckpfosten entsprechend große zylindrische Ausnehmungen 5 vorgesehen, die die Nocken der jeweils unteren Palette aufnehmen. Um die Eckverbindung zwischen Eckpfosten 21a, 21b.und Rahmenlängsrohr 22a zu stabilisieren, sind dort Winkelbleche 38 vorgesehen.As can be seen from Figure 2, la, 1b and 1c, 1d are each connected in pairs by lower stiffening struts 3a, 3b parallel to the upper longitudinal frame tubes, which prevent the corner posts from spreading apart when the pallet is loaded. On the other hand, no connection is provided on the transverse side of the pallet, between the
Die Figuren 8 und 9 zeigen eine alternative Ausführungsform der erfindungsgemäßen Palette, bei der der Aufnahmekörper für das Ladegut aus einer einstückigen Blechwanne 40 mit im wesentlichen U-förmigem Querschnitt besteht. Um ein problemloses ineinander stapeln mehrerer Paletten zu ermöglichen, verlaufen die Seitenwände 42 der Blechwanne 40 zum Palettenboden 43 hin schwach konisch. Da die größte Abmessung des Aufnahmekörpers in Längsrichtung der Palette Z wiederum geringer sein muß als der Abstand der Innenkanten der Rahmenquerrohre Y, sind horizontale Distanzstücke 44 vorgesehen, die die Seitenwände 42 der Blechwanne mit den Rahmenquerrohren 6a, 6b verbinden. Die Anzahl der Paletten, die ineinander gestapelt werden können, wird wiederum von der Breite des Zwischenraums 41 zwischen der Aussenkante 45 der Blechwanne und dem Rahmenlängsrohr und auch von der Rohrbreite des Eckpfostens bestimmt.FIGS. 8 and 9 show an alternative embodiment of the pallet according to the invention, in which the receiving body for the cargo consists of a one-piece
Wie in Figur 1 angedeutet ist, können weitere vertikale Zwischenstreben 14 an den Längsseiten der Palette zur Verbindung der Rahmenlängsrohre 2a, 2b mit den unteren Versteifungsstreben 3a, 3b vorgesehen sein. Das kompakte ineinander stapeln der Paletten wird durch diese Zwischenstreben 14 nicht behindert. Die Fläche zwischen Rahmenlängsrohr 2a und Versteifungsstrebe 3a an der Paletten-Längsseite kann sogar beispielsweise durch ein Blech ganz geschlossen sein, was den Vorteil hat, das dann auch an den Längsseiten der Palette ein Herausfallen des Ladegutes verhindert wird.As indicated in FIG. 1, further vertical
