Description

Die Erfindung betrifft eine Palette, bestehend aus einem Rahmen und einem in dem Rahmen lösbar gehalterten Bodeneinsatz, wobei der Rahmen aus Rahmenwänden aus stranggepreßten Hohlprofilen besteht.The invention relates to a pallet consisting of a frame and a bottom insert detachably held in the frame, the frame consisting of frame walls made of extruded hollow profiles.

Derartige Paletten dienen insbesondere zur Aufnahme und zum entnahmebereiten Lagern von Gegenständen, wie Montageteilen, die zur Weiterverarbeitung von einem Industrieroboter entnommen werden. Demzufolge müssen die Paletten sehr genau relativ zu dem Roboter angeordnet bzw. positioniert werden, damit auch die Gegenstände lagefixiert sind und so von dem Roboter ergriffen werden können. Innerhalb der Palette werden die Gegenstände durch die speziell angepaßten Bodeneinsätze fixiert, indem sie beispielsweise in entsprechende Aufnahmevertiefungen oder zwischen Erhebungen eingelegt sind. Daher ist es für ein Lagern verschiedener Gegenstände stets erforderlich, auch unterschiedliche Bodeneinsätze zu verwenden, so daß es erwünscht ist, für eine Mehrfachverwendung des Rahmens die Bodeneinsätze entsprechend auszuwechseln.Such pallets are used in particular for receiving and storing objects, such as assembly parts, ready for removal, which are removed for further processing by an industrial robot. As a result, the pallets must be arranged or positioned very precisely relative to the robot so that the objects are also fixed in position and can thus be gripped by the robot. The objects are fixed within the pallet by the specially adapted floor inserts, for example in that they are inserted into corresponding receiving recesses or between elevations. Therefore, it is always necessary to use different floor inserts for storing different objects, so that it is desirable to change the floor inserts accordingly for multiple use of the frame.

Eine Palette der eingangs genannten Art ist aus dem DE-GM 88 10 402 bekannt. Hierbei wird der Bodeneinsatz in dem Rahmen über eine Rastverbindung befestigt. Die Rahmenwände sind als stranggepreßte Kunststoff-Hohlprofile ausgebildet. Diese Palette hat sich bewährt, jedoch besteht bei manchen Anwendungsfällen der Bedarf, den Bodeneinsatz ohne unmittelbare Verbindung mit den Rahmenwänden in den Rahmen einlegen zu können und hierdurch die Handhabung zu erleichtern.A range of the type mentioned is known from DE-GM 88 10 402. Here, the floor insert is fastened in the frame via a snap connection. The frame walls are designed as extruded hollow plastic profiles. This range has proven itself, but in some applications there is a need to be able to insert the floor insert into the frame without a direct connection to the frame walls, thereby making handling easier.

Der Erfindung liegt daher die Aufgabe zugrunde, ausgehend von einer Palette der gattungsgemäßen Art, diese derart zu verbessern, daß ein einfaches Einlegen des Bodeneinsatzes in den Rahmen erfolgen kann, wobei dennoch eine sichere, präzise und stabile Aufnahme gewährleistet sein soll.The invention is therefore based on the object, starting from a pallet of the generic type, to improve it in such a way that the floor insert can be simply inserted into the frame, yet a safe, precise and stable reception should be ensured.

Erfindungsgemäß wird dies dadurch erreicht, daß die Rahmenwände nach innen in den von dem Rahmen umschlossenen Bereich ragende, als einstückig angeformte Hohlprofilabschnitte ausgebildet Auflagestege zur Auflage des Bodeneinsatzes aufweisen.According to the invention, this is achieved in that the frame walls have inward protrusions in the area enclosed by the frame and formed as a one-piece hollow profile sections for supporting the floor insert.

Durch die erfindungsgemäße Ausgestaltung braucht der Bodeneinsatz lediglich von oben in den Rahmen eingelegt zu werden, bis er zur Auflage auf den Auflagestegen gelangt. Ein Auswechseln ist daher besonders einfach. Aufgrund der Ausgestaltung der Auflagestege als Hohlprofilabschnitte ist eine hohe Stabilität gewährleistet, so daß auch schwere Gegenstände in der erfindungsgemäßen Palette gelagert werden können.Due to the design according to the invention, the floor insert only needs to be inserted into the frame from above until it comes to rest on the support webs. Replacement is therefore particularly easy. Due to the design of the support webs as hollow profile sections, high stability is ensured, so that even heavy objects can be stored in the pallet according to the invention.

In einer vorteilhaften Weiterbildungen der Erfindung weisen die Auflagestege in ihren dem Bodeneinsatz zugekehrten Oberseiten jeweils parallel zu den Rahmenwänden verlaufende Haltenuten auf. Ferner besitzt der Bodeneinsatz auf seiner auf den Auflagestegen zur Auflage kommenden Unterseite Halteansätze, die vorzugsweise formschlüssig in die Haltenuten der Auflagestege eingreifen. Hierdurch wird einerseits die Stabilität noch erhöht, da ein möglicherweise bei Belastung auftretendes Aufspreizen der Rahmenwände nach außen verhindert wird, indem diese durch den Bodeneinsatz bzw. dessen in die Haltenuten eingreifende Halteansätze zusammengehalten werden. Andererseits wird auch eine sehr genaue Positionierung des Bodeneinsatzes relativ zu dem Rahmen, und damit auch eine exakte Positionierung der in der Palette gelagerten Gegenstände erreicht.In an advantageous development of the invention, the support webs each have, in their upper sides facing the floor insert, holding grooves running parallel to the frame walls. Furthermore, the bottom insert has on its underside which comes to rest on the support webs, which preferably engage in a form-fitting manner in the holding grooves of the support webs. On the one hand, this increases the stability, since a spreading of the frame walls to the outside, which may occur when there is a load, is prevented by holding them together by means of the floor insert or its retaining lugs engaging in the retaining grooves. On the other hand, a very precise positioning of the floor insert relative to the frame, and thus also an exact positioning of the objects stored in the pallet, is achieved.

Zur weiteren Erhöhung der Stabilität ist es vorteilhaft, wenn der Bodeneinsatz mit den Auflagestegen zusätzlich über Nietverbindungen verbunden ist. Hierzu ist die Ausgestaltung der Auflagestege als Hohlprofilabschnitte insofern von besonderem Vorteil, als hierdurch die Nietverbindungen jeweils als Blindniet ausgebildet sein können, der sich durch den Bodeneinsatz und durch eine obere Wandung des Auflagesteges hindurch in einen Hohlraum des den Auflagesteg bildenden Hohlprofilabschnittes hinein erstreckt. Die erfindungsgemäße Palette bzw. der Rahmen kann hierdurch eine untere, durchgehende, ebene Standfläche besitzen, die von unteren Wandungen der Auflagestege sowie von unteren Endflächen der Rahmenwände gebildet wird. Die Standfläche ist dabei vorteilhafterweise nicht von Nietköpfen der Nietverbindungen beeinträchtigt, da diese ja verdeckt innerhalb des jeweiligen Hohlraums angeordnet sind. Zudem ist die Standfläche vorzugsweise jeweils senkrecht zu den von den Rahmenwänden definierten Ebenen, d.h. parallel zu einer von dem Bodeneinsatz definierten Bodenfläche, angeordnet. Die glatte Standfläche der erfindungsgemäßen Palette ist für eine Stapelbarkeit, die im folgenden noch genauer beschrieben wird, von Vorteil, da Beschädigungen der jeweils unteren Palette nahezu ausgeschlossen sind. Ferner kann die Palette auch gut auf einem ebenen Untergrund verschoben werden.To further increase the stability, it is advantageous if the floor insert is additionally connected to the support webs via rivet connections. To this end, the configuration of the support webs as hollow profile sections is particularly advantageous in that the rivet connections can each be designed as a blind rivet which extends through the bottom insert and through an upper wall of the support web into a cavity of the hollow profile section forming the support web. The pallet or frame according to the invention can hereby have a lower, continuous, flat standing surface which is formed by lower walls of the support webs and by lower end surfaces of the frame walls. The footprint is advantageously not affected by the rivet heads of the rivet connections, since these are arranged concealed within the respective cavity. In addition, the base is preferably perpendicular to the planes defined by the frame walls, i.e. arranged parallel to a floor area defined by the floor insert. The smooth footprint of the pallet according to the invention is advantageous for stackability, which will be described in more detail below, since damage to the respective lower pallet is almost impossible. The pallet can also be moved on a flat surface.

Weitere vorteilhafte Ausgestaltungsmerkmale der Erfindung sind in den Unteransprüchen sowie der folgenden Beschreibung enthalten.Further advantageous design features of the invention are contained in the subclaims and the following description.

In den verschiedenen Zeichnungsfiguren sind gleiche Teile stets mit den gleichen Bezugsziffern bezeichnet.In the various drawing figures, the same parts are always designated with the same reference numbers.

Eine in Fig. 1 und 2 jeweils dargestellte, erfindungsgemäße Palette 2 besteht aus einem Rahmen 4 und einem lösbar in dem Rahmen 4 gehalterten Bodeneinsatz 6. Der Rahmen 4 ist vorzugsweise rechteckig aus vier senkrecht zur Bodenfläche angeordneten Rahmenwänden 8 gebildet.A pallet 2 according to the invention shown in FIGS. 1 and 2 consists of a frame 4 and a bottom insert 6 detachably held in the frame 4. The frame 4 is preferably formed rectangularly from four frame walls 8 arranged perpendicular to the bottom surface.

Wie insbesondere in Fig. 3 zu erkennen ist, bestehen die Rahmenwände 8 aus stranggepreßten Hohlprofilen 10 insbesondere aus Kunststoff. Zur lösbaren Halterung des Bodeneinsatzes 6 weisen die Rahmenwände 8 nun erfindungsgemäß nach innen in den von dem Rahmen 4 umschlossenen Bereich ragende, als einstückig angeformte Hohlprofilabschnitte 12 ausgebildete Auflagestege 14 zur Auflage des Bodeneinsatzes 6 auf. Hierdurch braucht der Bodeneinsatz 6 lediglich von oben in Pfeilrichtung 15 (Fig. 3) in den Rahmen 4 eingelegt zu werden. Die Auflagestege 14 besitzen aufgrund ihrer Ausgestaltung als Hohlprofilabschnitte 12 eine hohe Stabilität, die erfindungsgemäß noch dadurch gesteigert werden kann, daß die Hohlprofilabschnitte 12 jeweils über mindestens einen insbesondere etwa senkrecht zur Bodenebene verlaufenden Versteifungssteg 16 in mindestens zwei Hohlräume 18 unterteilt sind. Der Versteifungssteg 16 erstreckt sich dabei einstückig zwischen einer oberen Wandung 20 und einer unteren Wandung 22 des Hohlprofilabschnittes 12. Die obere Wandung 20 und die untere Wandung 22 des Hohlprofilabschnittes 12 sind erfindungsgemäß unmittelbar an eine Innenwandung 23 des die Rahmenwand 8 bildenden Hohlprofils 10 angeformt. Der hierdurch zwischen der oberen und der unteren Wandung 20, 22 liegende, zu dem Versteifungssteg 16 parallele Abschnitt 23a der Innenwandung 23 trägt vorteilhafterweise ebenfalls zu einer sehr hohen Steifigkeit und Stabilität des Auflagesteges 14 bei.As can be seen in particular in FIG. 3, the frame walls 8 consist of extruded hollow profiles 10, in particular of plastic. For detachable mounting of the bottom insert 6, the frame walls 8 now have, according to the invention, support webs 14, which protrude inwards into the area enclosed by the frame 4, and are designed as integrally molded hollow profile sections 12 for supporting the bottom insert 6. As a result, the bottom insert 6 need only be inserted into the frame 4 from above in the direction of the arrow 15 (FIG. 3). The support webs 14 have a high stability due to their design as hollow profile sections 12, which can be increased according to the invention in that the hollow profile sections 12 are each divided into at least two cavities 18 by at least one stiffening web 16, in particular approximately perpendicular to the floor plane. The stiffening web 16 extends in one piece between an upper wall 20 and a lower wall 22 of the hollow profile section 12. According to the invention, the upper wall 20 and the lower wall 22 of the hollow profile section 12 are molded directly onto an inner wall 23 of the hollow profile 10 forming the frame wall 8. The section 23a of the inner wall 23 which is thereby located between the upper and lower walls 20, 22 and is parallel to the stiffening web 16 advantageously also contributes to a very high rigidity and stability of the support web 14.

Gemäß Fig. 3 und 4 weisen die Auflagestege 14 in ihren dem Bodeneinsatz 6 zugekehrten Oberseiten jeweils parallel zu den Rahmenwänden 8 verlaufende Haltenuten 24 auf. Diese Haltenuten 24 sind vorzugsweise durch einen sickenförmigen Verlauf der oberen Wandungen 20 gebildet. Dabei ist jeweils der oben erwähnte Versteifungssteg 16 vorzugsweise im Bereich dieser Haltenuten 24 angeordnet. Ferner besitzt der Bodeneinsatz 6 auf seiner auf den Auflagestegen 14 aufliegenden Unterseite Halteansätze 26, die vorzugsweise formschlüssig in die Haltenuten 24 eingreifen. Die Halteansätze 26 können als Längsstege oder als Stegabschnitte ausgebildet sein. Dabei können die Halteansätze 26 - gemäß Fig. 3 - auch durch eine sickenförmige Ausgestaltung im Randbereich des Bodeneinsatzes 6 gebildet sein.According to FIGS. 3 and 4, the support webs 14 in their upper sides facing the floor insert 6 each have holding grooves 24 running parallel to the frame walls 8. These holding grooves 24 are preferably formed by a bead-shaped course of the upper walls 20. The above-mentioned stiffening web 16 is preferably arranged in the region of these holding grooves 24. Furthermore, the bottom insert 6 has holding projections 26 on its underside resting on the support webs 14, which preferably engage in a form-fitting manner in the holding grooves 24. The retaining lugs 26 can be designed as longitudinal webs or as web sections. 3 - can also be formed by a bead-like configuration in the edge region of the bottom insert 6.

Zweckmäßigerweise bilden die unteren Wandungen 22 der die Auflagestege 14 bildenden Hohlprofilabschnitte 12 zusammen mit unteren Endflächen 28 der Rahmenwände 8 eine durchgehende, ebene, vorzugsweise senkrecht zu den Rahmenwänden 8 angeordnete Standfläche 30. Dabei kann - gemäß Fig. 4 - der Bodeneinsatz 6 im Randbereich derart gekröpft sein, daß seine untere Fläche 32 im wesentlichen auf der von der Standfläche 30 des Rahmens 4 definierten Ebene angeordnet ist. Alternativ hierzu ist in Fig. 3 dargestellt, daß die untere Fläche 32 des Bodeneinsatzes 6 auf der von der Oberseite der oberen Wandung 20 der Auflagestege 14 definierten Ebene aufliegt.Advantageously, the lower walls 22 of the hollow profile sections 12 forming the support webs 14, together with lower end faces 28 of the frame walls 8, form a continuous, flat standing surface 30, which is preferably arranged perpendicular to the frame walls 8. According to FIG. 4, the base insert 6 in the edge area can be such be cranked that its lower surface 32 is arranged substantially on the plane defined by the standing surface 30 of the frame 4. As an alternative to this, it is shown in FIG. 3 that the lower surface 32 of the base insert 6 rests on the plane defined by the upper side of the upper wall 20 of the support webs 14.

Zur weiteren Erhöhung der Stabilität ist gemäß Fig. 3 der Bodeneinsatz 6 mit den Auflagestegen 14 zusätzlich über Nietverbindungen 34, oder aber über sonstige Verbindungsmittel, wie Schraubverbindungen, Kunststoffstopfen oder dergleichen, verbunden. Vorzugsweise ist jeweils ein Blindniet (Hohlraumniet) 36 vorgesehen, der sich durch den Bodeneinsatz 6 und durch die obere Wandung 20 des Auflagesteges 14 hindurch in den Hohlraum 18 des den Auflagesteg 14 bildenden Hohlprofilabschnittes 12 hinein erstreckt. Hierdurch sind vorteilhafterweise im Bereich der unteren Standfläche 30 keinerlei störende Nietköpfe oder dergleichen angeordnet. Vielmehr ist aufgrund der verdeckt angeordneten Blindnieten 36 die ebene Standfläche 30 gewährleistet. Die Nietverbindung 34 ist in Fig. 4 lediglich durch eine Strichpunktlinie angedeutet. Des weiteren kann es in der Ausgestaltung nach Fig. 3 besonders vorteilhaft sein, die Nietverbindung 34 im Bereich des sickenförmig ausgebildeten Halteansatzes 26 anzuordnen, so daß zusätzlich auch eine glatte Oberfläche des Bodeneinsatzes 6 ohne störende Nietköpfe oder dergleichen erreicht wird.To further increase the stability, the floor insert 6 is additionally connected to the support webs 14 via rivet connections 34, or else via other connecting means, such as screw connections, plastic plugs or the like, according to FIG. A blind rivet (cavity rivet) 36 is preferably provided in each case, which extends through the bottom insert 6 and through the upper wall 20 of the support web 14 into the cavity 18 of the hollow profile section 12 forming the support web 14. As a result, no disturbing rivet heads or the like are advantageously arranged in the region of the lower standing surface 30. Rather, the flat standing surface 30 is ensured due to the concealed blind rivets 36. The rivet connection 34 is only indicated in FIG. 4 by a chain line. Furthermore, in the embodiment according to FIG. 3, it can be particularly advantageous to arrange the rivet connection 34 in the region of the bead-shaped retaining projection 26, so that, in addition, a smooth surface of the bottom insert 6 is achieved without disturbing rivet heads or the like.

In der Ausführungsform nach Fig. 1 ist der Bodeneinsatz 6 als durchgehende Bodenplatte 38 ausgebildet, die hinsichtlich ihrer Größe bzw. Flächenform der von dem Rahmen 4 umschlossenen Fläche entspricht. Alternativ hierzu besteht der Bodeneinsatz 6 in der in Fig. 2 dargestellten Ausführungsform aus mehreren, insbesondere zwei sich parallel zueinander zwischen gegenüberliegenden Rahmenwänden 8 erstreckenden Bodentraversen 40. Sowohl die Bodenplatte 38 als auch die Bodentraversen 40 besitzen zweckmäßigerweise nicht dargestellte Ansätze, Erhebungen und/oder Vertiefungen, die zur genau positionierten Aufnahme von ebenfalls nicht dargestellten Gegenständen dienen. Die Bodentraversen 40 weisen vorzugsweise hochstehende, derart kammartig angeordnete Ansätze auf, daß die jeweils zwischen den Ansätzen gebildeten Zwischenräume in einer zu den Bodentraversen 40 senkrechten Richtung fluchten. Hierdurch können auf den Bodentraversen 30 längliche Gegenstände aufgelegt werden, die dann zwischen den kammartigen Ansätzen genau fixiert und positioniert werden. Es liegt zudem im Rahmen der Erfindung, auf der Bodenplatte 38 bzw. auf den Bodentraversen 40 entsprechend ausgebildete Aufnahmeteile als gesonderte Einzelteile lösbar - z.B. über Rastverbindungen "aufklipsbar" - zu befestigen (nicht dargestellt).In the embodiment according to FIG. 1, the base insert 6 is designed as a continuous base plate 38 which corresponds in size or surface shape to the surface enclosed by the frame 4. As an alternative to this, the floor insert 6 in the embodiment shown in FIG. 2 consists of several, in particular two floor cross members 40 extending parallel to one another between opposite frame walls 8. Both the floor plate 38 and the floor Traverses 40 have expediently not shown approaches, elevations and / or depressions, which are used for precisely positioned accommodation of objects, also not shown. The floor traverses 40 preferably have upstanding lugs arranged in the manner of a comb in such a way that the gaps formed between the lugs are aligned in a direction perpendicular to the floor traverses 40. In this way, elongated objects can be placed on the floor cross members 30, which are then precisely fixed and positioned between the comb-like approaches. It is also within the scope of the invention to fasten correspondingly designed receiving parts as separate individual parts on the base plate 38 or on the crossbeams 40, for example “snap-on” via snap-in connections (not shown).

Wie weiterhin in Fig. 3 zu erkennen ist, sind die die Rahmenwände 8 bildenden Hohlprofile 10 zur Erhöhung der Stabilität vorteilhafterweise über mehrere, in Profillängsrichtung sowie parallel zur Bodenfläche verlaufende Versteifungsstege 42 in mehrere übereinanderliegende Hohlräume 44 unterteilt. Der an die Rahmenwand 8 angrenzende Hohlraum 18 des Auflagesteges 14 ist von einem dieser Hohlräume 44, und zwar von dem der unteren Endfläche 28 nächstliegenden, "untersten" Hohlraum 44 über die Innenwandung 23 des Hohlprofils 10 getrennt. Weiterhin besitzen die Hohlprofile 10 vorteilhafterweise auf ihren Innenseiten 46 sowie auch auf ihren Außenseiten 48 - jeweils bezogen auf den Rahmen 4 - in Profillängsrichtung verlaufende, insbesondere im Bereich der Versteifungsstege 42 angeordnete Versteifungssicken 50.As can also be seen in FIG. 3, the hollow profiles 10 forming the frame walls 8 are advantageously subdivided into a plurality of cavities 44 one above the other via a plurality of stiffening webs 42 running in the longitudinal direction of the profile and parallel to the base surface. The cavity 18 of the support web 14 adjoining the frame wall 8 is separated from one of these cavities 44, specifically from the "bottom" cavity 44 closest to the lower end face 28 via the inner wall 23 of the hollow profile 10. Furthermore, the hollow profiles 10 advantageously have stiffening beads 50 running in the longitudinal direction of the profile, in particular in the area of the stiffening webs 42, on their inner sides 46 and also on their outer sides 48, in each case with respect to the frame 4.

Gemäß Fig. 1 und 2 besitzen zumindest zwei gegenüberliegende Rahmenwände 8 längliche Grifföffnungen 52. Gemäß Fig. 3 sind diese Grifföffnungen 52 vorzugsweise derart im Bereich zwischen zwei benachbarten Versteifungsstegen 42 des Hohlprofils 10 gebildet, daß die Versteifungsstege 42 die oberen und unteren Begrenzungen der Grifföffnungen 52 bilden.1 and 2, at least two opposite frame walls 8 have elongated handle openings 52. According to FIG. 3, these handle openings 52 are preferably formed in the region between two adjacent stiffening webs 42 of the hollow profile 10 in such a way that the stiffening webs 42 define the upper and lower boundaries of the handle openings 52 form.

Die Rahmenwände 8 können in den Eckbereichen des Rahmens 4 unlösbar, insbesondere stoffschlüssig miteinander verbunden sein. In der dargestellten, bevorzugten Ausführungsform der Erfindung sind die Rahmenwände 8 jedoch lösbar über Steckverbinderelemente 54 miteinander verbunden, wie dies in Fig. 6 veranschaulicht ist. In jedem Eckbereich des Rahmens 4 ist eines dieser Steckverbinderelemente 54 angeordnet, welches aus einem im vertikalen Querschnitt den Rahmenwänden 8 angepaßten Eckkörper 56 besteht, der in zwei rechtwinklig zueinander angeordnete Richtungen weisende und in die Hohlräume 44 der Hohlprofile 10 sowie auch in die Hohlräume 18 der Auflageansätze 14 von der offenen Profil-Stirnseite her eingreifende Steckansätze 58 aufweist. Dadurch, daß diese Verbindung erfindungsgemäß auch im Bereich der Auflageansätze 14 erfolgt, wird ebenfalls deren Stabilität derart gesteigert, daß auch besonders schwere Gegenstände aufgenommen werden können. Die Steckverbinderelemente 54 können mit den Rahmenwänden 8 zusätzlich über Rastverbindungen oder stoffschlüssig (dann unlösbar) verbunden sein. Die Montage des Rahmens 4 ist durch die Erfindung sehr einfach und schnell durchführbar, indem lediglich jeweils eine Rahmenwand 8 und ein Steckverbinderelement 54 in Richtung der in Fig. 6 eingezeichneten Pfeile 59 zusammengesteckt zu werden brauchen.The frame walls 8 can be non-detachably, in particular cohesively connected to one another in the corner regions of the frame 4. In the preferred embodiment of the invention shown, however, the frame walls 8 are detachably connected to one another via connector elements 54, as is illustrated in FIG. 6. In each corner region of the frame 4, one of these connector elements 54 is arranged, which consists of a corner body 56 which is adapted to the frame walls 8 in vertical cross section and which points in two directions arranged at right angles to one another and into the cavities 44 of the hollow profiles 10 and also into the cavities 18 in FIG Has bearing lugs 14 engaging plug-in lugs 58 from the open profile end face. Because this connection according to the invention also takes place in the area of the support lugs 14, their stability is also increased in such a way that particularly heavy objects can also be accommodated. The connector elements 54 can also be connected to the frame walls 8 via snap-in connections or integrally (then inseparably). The assembly of the frame 4 can be carried out very simply and quickly by the invention, in that only one frame wall 8 and one connector element 54 need to be plugged together in the direction of the arrows 59 shown in FIG. 6.

In einer besonders vorteilhaften Weiterbildung der Erfindung ist die Palette 2 stapelbar und dabei insbesondere selbstzentrierend und selbstfixierend ausgebildet. Dies wird erfindungsgemäß dadurch erreicht, daß der Rahmen 4 im Bereich seiner oberen und unteren Ränder jeweils in Negativkontur zueinander ausgebildete Führungsstege 60 aufweist (siehe insbesondere Fig. 3 und 5). Diese Führungsstege 60 verlaufen in Längsrichtung der Rahmenwände 8 und weisen jeweils eine maximal der halben Dicke der Rahmenwände 8 entsprechende Dicke auf. Dabei ist einer der Führungsstege 60 mit der Außenseite 48 der Rahmenwände 8 und der andere Führungssteg 60 mit der Innenseite 46 der Rahmenwände 8 fluchtend angeordnet. Im dargestellten Ausführungsbeispiel ist der obere Führungssteg 60 im äußeren Bereich und der untere Führungssteg 60 im inneren Bereich der Rahmenwände 8 angeordnet. Dabei ist es besonders vorteilhaft, wenn die in gestapeltem Zustand - wie in Fig. 5 dargestellt - einander zugekehrten Seitenflächen 62 der nebeneinander angeordneten Führungsstege 60 zweier gestapelter Paletten 2 bzw. Rahmen 4 derart schräg angeordnet sind, daß sich die Führungsstege 60 in Richtung ihrer freien Enden verjüngen. Dabei sind die Führungsstege 60 hinsichtlich ihrer Breite derart dimensioniert, daß zwischen den Führungsstegen 60 zweier gestapelter Paletten 2 bzw. Rahmen 4 ein Seitenspiel von etwa 1 mm vorhanden ist. Die Führungsstege 60 besitzen eine obere Endfläche 64 bzw. die bereits erwähnte untere Endfläche 28, mit denen sie im gestapelten Zustand auf ebenen, den Führungsstegen 60 jeweils benachbarten Auflageflächen 66 des jeweils anderen Rahmens 4 zur Auflage kommen.In a particularly advantageous development of the invention, the pallet 2 is stackable and in particular is self-centering and self-fixing. This is achieved according to the invention in that the frame 4 has guide webs 60 which are each formed in a negative contour to one another in the region of its upper and lower edges (see in particular FIGS. 3 and 5). These guide webs 60 run in the longitudinal direction of the frame walls 8 and each have a maximum thickness corresponding to half the thickness of the frame walls 8. One of the guide webs 60 is arranged in alignment with the outside 48 of the frame walls 8 and the other guide web 60 with the inside 46 of the frame walls 8. In the exemplary embodiment shown, the upper guide web 60 is arranged in the outer region and the lower guide web 60 in the inner region of the frame walls 8. It is particularly advantageous if, in the stacked state - as shown in Fig. 5 - facing side surfaces 62 of the side-by-side guide webs 60 of two stacked pallets 2 or frames 4 are arranged obliquely such that the guide webs 60 are in the direction of their free Taper ends. The width of the guide webs 60 is such that there is a side play of approximately 1 mm between the guide webs 60 of two stacked pallets 2 or frames 4. The guide webs 60 have an upper end surface 64 or the already mentioned lower end surface 28, with which they come to rest in the stacked state on flat support surfaces 66 of the other frame 4 which are adjacent to the guide webs 60.

Durch diese vorteilhafte Ausgestaltung wird erreicht, daß bei einem Aufsetzen einer Palette 2 in Pfeilrichtung 68 gemäß Fig. 5 auf eine untere Palette 2 eine Zwangsführung über Einführschrägflächen (Seitenflächen 62 der Führungsstege 60) derart erfolgt, daß die obere Palette aufgrund der schrägen Seitenflächen 62 der Führungsstege 60 beim Aufsetzen in Pfeilrichtung 68 genau in eine mit der unteren Palette fluchtende Anordnung geführt wird (Selbstzentrierung). Dies ist für die angestrebte, genaue Positionierung besonders vorteilhaft. Die Führungsstege 60 erleichtern somit sowohl das verrutschfreie Aufsetzen als auch das Entnehmen der Paletten 2.This advantageous embodiment ensures that when a pallet 2 is placed in the direction of arrow 68 according to FIG. 5 on a lower pallet 2, there is a positive guidance via inclined insertion surfaces (side surfaces 62 of the guide webs 60) such that the upper pallet due to the oblique side surfaces 62 of the Guide webs 60 when placed in the direction of arrow 68 exactly in an alignment with the lower pallet ge leads (self-centering). This is particularly advantageous for the desired, precise positioning. The guide webs 60 thus facilitate both the slip-free placement and the removal of the pallets 2.

Wie oben bereits erwähnt, besteht der Rahmen 4 vorzugsweise aus Kunststoff. Der Bodeneinsatz 6 besteht vorzugsweise ebenfalls aus Kunststoff oder aber aus Aluminium.As already mentioned above, the frame 4 is preferably made of plastic. The floor insert 6 is preferably also made of plastic or aluminum.

Die Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsbeispiele beschränkt, sondern umfaßt auch alle im Sinne der Erfindung gleichwirkenden Ausführungsformen.The invention is not limited to the exemplary embodiments shown and described, but also encompasses all embodiments having the same effect in the sense of the invention.
