Abstract

The pallet support surface (1) is made from cellular pulp reinforced with rib profiles (5). On the underside of the support surface is a tear-resistant paper or cardboard blank (4) which has through-recesses (3) for the stud-like hollow feet (2) which are formed on it. This paper or cardboard blank is fixedly connected e.g. stuck to the underside of the support face at least in areas and preferably over the entire surface. The paper or cardboard blank is formed from a paper-based material impregnated with sodium silicate. The overall face of the support surface can be divided into groups in the intermediate areas between the openings of the feet and the groups can be profiled into multiple U-shaped indentations. The hollow feet can contain support inserts of recyclable material.

Description

Die Erfindung betrifft eine Palette zur Aufnahme und zum Transport von Lasten, bestehend aus einer aus Zellstoffpulpmaterial mindestens einlagig im Saugverfahren versteifungsprofiliert hergestellten Tragfläche mit daran ausgeformten, zur Tragfläche hin offenen, napfartigen Hohlfüßen.The invention relates to a pallet for receiving and Transport of loads consisting of a pulp material Stiffening profile at least one layer in the suction process manufactured wing with molded, cup-like hollow feet open to the wing.

Derartige Paletten sind bspw. nach den DE-U-296 03 642, DE-U-296 08 831 und auch nach der DE-A-296 11 920 bekannt. An solche Paletten, bei denen es sich um Massenartikel handelt, sind mehrfache Forderungen zu stellen, und zwar neben einfacher und kostengünstiger Herstellung ausreichende Festigkeit und Belastbarkeit. Die Paletten nach den oben bspw. genannten Druckschriften vermögen diesen Forderungen immer nur zum Teil genügen, d.h., der Wunschvorstellung insbesondere von Großbenutzern Paletten der eingangs genannten Art als Ersatz für die bislang im großen Umfange eingesetzten Holzpaletten zum Einsatz zu bringen, konnte bislang noch nicht ganz zufriedenstellend entsprochen werden. So hat sich gezeigt, daß bei mehr oder weniger starker punktueller Belastung der Tragfläche zwischen den Hohlfüßen, also wenn sich bspw. eine Person auf die Tragfläche stellt, sich diese zumindest durchbiegt und ggf. bei zu hoher Belastung reißt und/oder zu Bruch geht, und zwar trotz Rippenprofilierung und/oder doppellagiger Ausbildung der Tragfläche mit ihren Hohlfüßen. Bedingt ist dies durch die Eigenart des Pulpmaterials, das im ausgeformten Trockenzustand keine allzuhohe bzw. insbesondere für derartige punktuelle Belastungen keine ausreichende Biege- und Zugbelastbarkeit aufweist.Such pallets are, for example, according to DE-U-296 03 642, DE-U-296 08 831 and also known from DE-A-296 11 920. On such pallets that are mass-produced items, multiple demands must be made, in addition to simple and inexpensive to manufacture sufficient strength and resilience. The pallets according to the above mentioned publications are always able to meet these demands only partially sufficient, i.e. in particular the desired idea of large users pallets of the type mentioned as a replacement for the previously widely used Until now, it was still possible to use wooden pallets cannot be met quite satisfactorily. So it turned out shown that with more or less strong selective loading the wing between the hollow feet, so if For example, a person stands on the wing, at least this deflects and breaks if the load is too high and / or breaks, despite the rib profile and / or double-layer formation of the wing with their Hollow feet. This is due to the nature of the pulp material, not too high in the dry form or especially not for such selective loads has sufficient bending and tensile strength.

Ausgehend von Paletten der eingangs genannten Art, liegt der Erfindung die Aufgabe zugrunde, solche Paletten auf einfache Weise und ohne den bisherigen engen Kostenrahmen für die Herstellung solcher Paletten zumindest nicht wesentlich zu überschreiten, dahingehend zu verbessern, daß sie insbesondere derartigen punktuellen Belastungen besser widerstehen können, ohne deren Gesamtrecyclebarkeit zu beeinträchtigen. Starting from pallets of the type mentioned, the Invention the task of such pallets on simple Wise and without the previous tight budget for manufacturing at least not significantly exceed such pallets, to improve in particular can better withstand such selective loads, without affecting their overall recyclability.

Diese Aufgabe ist mit einer Palette der eingangs genannten Art nach der Erfindung dadurch gelöst, daß an der Unterseite der Tragfläche ein reißfester, mit Durchgriffsausnehmungen für die Hohlfüße versehener Papier- oder Kartonagenzuschnitt angeordnet und dieser mit der Unterseite der Trägerfläche mindestens punktuell fest verbunden ist.This task is with a range of those mentioned Kind according to the invention solved in that on the bottom the wing is tearproof, with penetration recesses paper or cardboard blank provided for the hollow feet arranged and this with the bottom of the support surface is firmly connected at least at certain points.

An der Palette selbst, für die im übrigen eine Strukturierung der Tragfläche im Sinne der DE-U-296 11 920 bevorzugt wird, d.h., weitestgehende Aufgliederung der Tragfläche in versteifende Rippenprofilierungsgruppen, ändert sich praktisch nichts. Als ganz entscheidend für die Erhöhung einer punktuellen Belastbarkeit hat sich überraschend die vorzugsweise` ganzflächig verklebte Anordnung eines solchen Papier- oder Kartonagenzuschnittes unter der Tragfläche erwiesen, der insofern gewissermaßen als Zuganker wirkt, als die Reißfestigkeit von Papier oder Kartonagen (bspw. auf Basis sogenannten Natronpapierrohstoffes) wesentlich höher ist als die des die Palette bildenden Pulpmaterials im trockenen Zustand. Hinzu kommt noch, daß sich durch den unterseitig bevorzugt ganzflächig angeklebten Papier- oder Kartonagenzuschnitt eine glatte Unterseite an der Palette ergibt, so daß bspw. Gabelstaplerarme beim Unterfassen der Palette nicht an den sich auf der Unterseite im Negativ verstellenden Rippenprofilierungen anstoßen bzw. sich an diesen verhaken können.On the pallet itself, for the rest of which a structuring the wing in the sense of DE-U-296 11 920 is preferred, i.e., the most extensive breakdown of the wing into stiffening Rib profiling groups, practically changes Nothing. As very crucial for the increase of a selective Resilience has surprisingly been preferred arrangement of such paper or glued over the entire surface Cardboard blank proved under the wing, the to a certain extent acts as a tie rod, as the tensile strength of paper or cardboard (e.g. based on so-called soda paper raw material) is significantly higher than that of the pulp material forming the pallet in the dry Status. Added to that is that by the underside preferably paper or cardboard blank glued over the entire surface gives a smooth underside on the pallet, so that For example, forklift arms are not on when reaching under the pallet the rib profiles on the underside which adjust negatively bump into or get caught on it.

Um sich nicht allein auf die stabilisierende Maßnahme der Anordnung eines reißfesten Papier- oder Kartonagenzuschnittes unter der Tragfläche verlassen zu müssen, besteht eine vorteilhafte Weiterbildung der Palette darin, daß man auch die Hohlfüße der Palette verstärkt, und zwar in der Weise, daß in den Hohlfüßen Stützeinsätze aus ebenfalls recyclebarem Material angeordnet sind, die sich vom Boden der Hohlfüße bis zur Oberflächenebene der Tragfläche erstrecken. Bei diesen Stützeinsätzen kann es sich um Rohrstücke aus Kartonage, um aus Wellpappe gewickelte Einsätze oder auch aus ebenfalls im Saugformverfahren hergestellte, topfartige Einsätze handeln, was im Einzelnen noch näher erläutert wird. In order not to rely solely on the stabilizing measure of the arrangement a tear-resistant paper or cardboard blank Having to leave under the wing is an advantageous one Further development of the range in that one also Hollow feet of the range reinforced, in such a way that in the hollow feet support inserts also made of recyclable Material are arranged that extend from the bottom of the hollow feet extend to the surface plane of the wing. With these Support inserts can be pieces of pipe made of cardboard inserts wrapped in corrugated cardboard or also in Pot-shaped inserts produced by suction molding processes, which is explained in more detail.

Möglich ist aber auch eine Weiterbildung dahingehend, daß außen auf die Hohlfüße formentsprechende, aber entsprechend vergrößerte, separat aus Pulpmaterial saugausgeformte Hohlfußkappen aufgesetzt sind, die mit ihren oberen Rändern die Ränder der Durchgriffsausnehmungen des Papier- oder Kartonagenzuschnittes abdecken und mit den Hohlfüßen und den Rändern verklebt sind, was ebenfalls noch näher erläutert wird.However, further training is also possible in that on the outside corresponding to the hollow feet, but corresponding enlarged hollow foot caps, separately molded from pulp material are placed, which with their upper edges Edges of the cut-outs of the paper or cardboard blank cover and with the hollow feet and the Edges are glued, which is also explained in more detail becomes.

Ebenfalls aus Festigkeits-, Stabilitäts- und Transportgründen sind solche Paletten sehr häufig mit sogenannten Kufenleisten ausgestattet, die mit den unteren Enden der Hohlfüße fest verbunden sind. Für deren Ausbildung sind schon die unterschiedlichsten Vorschläge gemacht worden, da diese ebenfalls in hohem Maße zur Stabilität solcher Paletten beitragen. Mit Rücksicht auf deren hohe Beanspruchung mußte man bislang davon Abstand nehmen, solche Kufenleisten, ebenfalls aus Pulpmaterial ausgeformt, zu verwenden, obgleich dies wegen der guten Recyclebarkeit in hohem Maße wünschenswert wäre, ganz abgesehen von der kostengünstigen Verarbeitbarkeit solchen Pulpmaterials. Diesbezüglich besteht unter Anwendung des gleichen vorerläuterten Zugankerprinzips, wie für die Trägerfläche der Palette selbst, eine vorteilhafte Weiterbildung darin, daß die unter den Hohlfüßen angeordneten Kufenleisten ebenfalls aus Zellstoffpulpmaterial im Saugformverfahren ausgeformt und diese zur Palette hin mit Rippenprofilierungen und Fußendenaufnahmeausnehmungen versehen sind, wobei mindestens palettenseitig auf den verrippten Bereichen zwischen den Aufnahmeausnehmungen Papier-bzw. Kartonagenzuschnitte angeordnet und diese mit den Kufenleisten verklebt sind.Also for reasons of strength, stability and transport such pallets are very often with so-called skid strips equipped with the lower ends of the hollow feet firmly are connected. The most varied are for their training Proposals have been made as well greatly contribute to the stability of such pallets. With So far, one had to consider their high demands distance from such skid strips, also from Molded pulp material to be used, although because of would be highly desirable for good recyclability, not to mention the inexpensive processability such pulp material. In this regard, there is application the same previously explained tie rod principle as for the Carrier surface of the pallet itself, an advantageous one Further training in that arranged under the hollow feet Skid strips also made of pulp pulp material using the suction molding process molded and this to the pallet Provide rib profiles and foot end recesses are, at least on the pallet side on the ribbed Areas between the receiving recesses paper or. Cardboard blanks arranged and these with the skid strips are glued.

Die erfindungsgemäße Palette und weitere vorteilhafte Ausführungsformen werden nachfolgend anhand der zeichnerischen Darstellung von Ausführungsformen näher erläutert.The range according to the invention and further advantageous embodiments are based on the graphic representation of embodiments explained in more detail.

Die Palette besteht nach wie vor aus einer aus Zellstoffpulpmaterial mindestens einlagig im Saugverfahren versteifungsprofiliert hergestellten Tragfläche 1 mit daran ausgeformten, zur Tragfläche 1 hin offenen, napfartigen Hohlfüßen 2, wobei an den jeweils in einer Reihe angeordneten Hohlfüßen 2 in möglicher Ausführungsform Kufenleisten KL aus, wie die Palette selbst, ebenfalls recyclebarem Material angeordnet sind (siehe hierzu insbesondere Fig. 2, 3).The pallet still consists of a cellulose pulp material Stiffening profile at least one layer in the suction process manufactured wing 1 with molded, towards the wing 1 open, cup-like hollow feet 2, being on the hollow feet arranged in a row 2 in a possible embodiment, skid strips KL, such as the Pallet itself, also made of recyclable material are (see in particular Fig. 2, 3).

Für eine solche Palette ist nun wesentlich, daß an der Unterseite der Tragfläche 1 ein reißfester, mit Durchgriffsausnehmungen 3 für die Hohlfüße 2 versehener Papier- oder Kartonagenzuschnitt 4 angeordnet und dieser mit der Unterseite der Tragfläche 1 mindestens punktuell fest verbunden ist. Vorzugsweise erfolgt die feste Verbindung zwischen dem Papier- bzw. Kartonagenzuschnitt 4 und der Unterseite der Tragfläche 1 durch eine ganzflächige Verklebung mit einem geeigneten, die Recyclebarkeit der ganzen Palette nicht behindernden Kleber. Orientiert an Fig. 4 ist ohne weiteres vorstellbar, daß auf die Tragfläche 1 wirkende Belastungen zwischen den Hohlfüßen 2 je nach Gewicht zu Durchbiegungen der Tragfläche 1 führen würden, die im Extrem auch zu deren Bruch führen könnten. Da nunmehr unter der Tragfläche 1 der Papier- bzw. Kartonagenzuschnitt 4 angeordnet ist, der wie ein Zuganker wirkt, wird dem entgegengewirkt. Um eine Vorstellung bzgl. der Tragfähigkeit einer solchen, erfindungsgemäß ausgebildeten Palette zu vermitteln, sei darauf hingewiesen, daß eine solche Palette in Normgröße bis zu 550 kg belastbar ist, d.h., auf diese können sich ohne weiteres fünf bis sechs erwachsene Personen stellen, ohne daß sich die Palette durchbiegt oder gar zu Bruch geht, was sonst zu beobachten war, wenn eine entsprechend ausgebildete Palette nicht durch den als Zuganker wirkenden Papier- bzw. Kartonagenzuschnitt verstärkt ist.For such a pallet it is now essential that on the bottom the wing 1 is a tearproof, with penetration recesses 3 for the hollow feet 2 provided paper or cardboard blank 4 arranged and this with the bottom of Wing 1 is firmly connected at least at certain points. Preferably there is a firm connection between the paper or Cardboard blank 4 and the underside of the wing 1 through a full-surface gluing with a suitable, the recyclability of the whole range of non-obstructive glue. Oriented to Fig. 4, it is easily conceivable that loads acting on the wing 1 between the Hollow feet 2 depending on the weight to deflect the wing 1 would lead, which in extreme cases also lead to their rupture could. Since the paper or Cardboard blank 4 is arranged, which is like a tie rod acts, is counteracted. To get an idea the load-bearing capacity of such, designed according to the invention To convey a range, it should be noted that a such a standard size pallet can be loaded up to 550 kg, that is, five to six can easily refer to these adults stand without the palette deflects or even breaks, what else can be observed was when a suitably trained palette didn't go through the paper or cardboard blank that acts as a tie rod is reinforced.

Für einen solchen Papier- bzw. Kartonagenzuschnitt kommt insbesondere Papiermaterial auf Natronbasis als sogenanntes Natronpapier mit entsprechend hoher Reißfestigkeit in Betracht, wobei sich gezeigt hat, daß in der Regel schon eine Papier- oder Kartonagenstärke in der Größenordnung von 0,3 - 0,6 mm dem gewünschten Verstärkungseffekt genügt. Bei einer Versteifungsprofilierung VP, wie bspw. und stark schematisiert in Fig. 1 dargestellt, der eine entsprechende "Negativstruktur" auf der Palettenoberseite entspricht, bedeutet die bevorzugte Verklebung "mit der in Fig. 1 dargestellten Unterseite" der Tragfläche 1 natürlich eine Verklebung mit den Rippenflächen F der Versteifungsprofilierungen VP.For such a paper or cardboard blank comes in particular Sodium-based paper material as so-called sodium paper with a correspondingly high tear resistance, It has been shown that a paper or Cardboard thickness in the order of 0.3 - 0.6 mm the desired reinforcing effect is sufficient. With a stiffening profile VP, such as and highly schematic in 1, which shows a corresponding "negative structure" on the top of the pallet means the preferred one Gluing "with the bottom shown in Fig. 1" of Wing 1, of course, an adhesive bond to the rib surfaces F of the stiffening profiles VP.

Wie aus Fig. 1 und 4 ersichtlich, ist die Tragfläche 1 der Palette durch eine Vielzahl sich parallel zu dern Längsrändern LR erstreckenden ersten Hohlrippen HR und durch sich parallel zu den Querrändern QR der Palette erstreckenden zweiten Hohlrippen HR' in eine Vielzahl von zur Tragfläche 1 hin offene Eintiefungen ET gegliedert. Diese Eintiefungen ET haben dabei Abmessungen bzgl. ihres offenen Querschnittes bspw. in der Größenordnung von 6 x 2 cm. Durch diese Rippengliederung ergeben sich auch nach unten offene Eintiefungen ET'.1 and 4, the wing 1 is the Pallet through a multitude parallel to the longitudinal edges LR extending first hollow ribs HR and through itself extending parallel to the transverse edges QR of the pallet second hollow ribs HR 'in a plurality of to the wing 1 structured open recesses ET. These depressions ET have dimensions with respect to their open cross-section for example in the order of 6 x 2 cm. Through this rib structure there are also depressions that are open at the bottom ET '.

Der offene Gesamtquerschnitt der Eintiefungen ET entspricht im wesentlichen der von den Oberflächen OF aller Hohlrippen HR gebildeten Tragfläche 1, und die zu den Hohlfüßen 2 unmittelbar benachbart angeordneten Eintiefungen ET münden offen in die Innenräume der Hohlfüße 2 aus, wie dies links oben in Fig.1 am dortigen Hohlfuß 2 verdeutlicht ist. Bezüglich der beiden Lagen aus Pulpmaterial, aus denen die ganze Palette einschließlich ihrer Hohlfüße 2 besteht, wird auf Fig. 4 verwiesen, in der die Doppellagigkeit durch eine gestrichelte Linie L angedeutet ist. Die Gesamtwandstärke S der aus zwei Lagen gebildeten Palette beträgt im übrigen etwa 8 bis 10 mm. Mit Rücksicht auf normale Palettengrößen, d.h., mit Abmessungen gemäß Euronorm 800 x 1.200 mm oder gemäß Industrienorm 1.000 x 1.200 mm bzw. 40 x 48 inch, ist die Palette insgesamt mit neun Hohlfüßen 2 versehen, von denen jeweils drei längs der Querränder QR und die restlichen drei in der Mitte der Palette angeordnet sind. Wesentlich für die Hohlrippen ist, daß deren Wände W, wie in Fig. 4 dargestellt, abgesehen von ihrer schwach geneigten Erstreckung, im wesentlichen senkrecht zur Tragfläche 1 orientiert und im Querschnitt nicht etwa wellenförmig ausgebildet sind, da wellenförmige Hohlrippen weniger Widerstand gegen eine Auflast und ebenso gegen den Druck von unten von unterfahrenen Tragarmen von bspw. Gabelstaplern bieten würden. Eine solche bevorzugt vorgesehene Strukturierung der Tragfläche 1 trägt natürlich ebenfalls mit zur Tragfähigkeit der Palette bei, entscheidend für die oben erwähnte Belastbarkeit ist jedoch der untergeklebte Papier- bzw. Kartonagenzuschnitt. The total open cross section of the recesses ET corresponds essentially that of the surfaces OF of all hollow ribs HR formed wing 1, and the 2 to the hollow feet immediately adjacent recesses ET open open into the interiors of the hollow feet 2 as shown on the left is shown above in Figure 1 on the hollow foot 2 there. Regarding the two layers of pulp material from which the entire range, including their hollow feet 2, will to Fig. 4, in which the double layer by a dashed line L is indicated. The total wall thickness S the pallet formed from two layers is approximately 8 to 10 mm. With regard to normal pallet sizes, i.e. with dimensions according to Euronorm 800 x 1,200 mm or according to The industry standard is 1,000 x 1,200 mm or 40 x 48 inch Pallet provided with a total of nine hollow feet 2, of which three each along the transverse edges QR and the remaining three are arranged in the middle of the pallet. Essential for that Hollow ribs is that their walls W, as shown in Fig. 4, apart from their slightly inclined extension, in oriented substantially perpendicular to the wing 1 and in Cross-section are not approximately wavy, because wavy hollow ribs less resistance to one Load and also against the pressure from below from offer underneath support arms of forklifts, for example would. Such a preferably provided structuring of the Wing 1 naturally also contributes to the load-bearing capacity the range, crucial for the resilience mentioned above is, however, the paper or cardboard blank that is glued under.

Zur verstärkenden und die Stabilität der Palette hinsichtlich auch einer punktuellen Belastung insbesondere im Umfeld der Hohlfüße 2 erhöhenden Weiterbildung tragen solche ebenfalls bei, bei denen zum einen in den Hohlfüßen 2 formentsprechende, aber entsprechend außenmaßreduzierte, separat aus Pulpe saugausgeformte, topfartige Fußeinsätze 6 angeordnet und diese mit den Hohlfußinnenwandungen 2' verklebt sind. Hierzu wird auf den links in Fig. 4 dargestellten Hohlfuß 2 verwiesen. Möglich ist aber zum anderen eine diesbezügliche und ebenfalls der Einfachheit halber ebenfalls in Fig. 4 am mittleren Hohlfuß 2 mit dargestellte Ausführungsform, bei der außen an den Hohlfüßen 2 formentsprechende, aber entsprechend vergrößerte, separat aus Pulpe saugausgeformte Kappen 7 angeordnet sind, die mit ihren oberen Rändern 7' die Ränder 3' der Durchgriffsausnehmungen 3 des Papier-bzw. Kartonagenzuschnittes 4 abdecken und mit den Hohlfüßen 2 und den Rändern 3' des Kartonagenzuschnittes 4 verklebt sind. Da die "Bewehrungen", sprich Papier- bzw. Kartonagenzuschnitte 4 und die Hohlfußverstärkungen vorzugsweise per se verklebt werden, besteht diesbezüglich eine vorteilhafte Weiterbildung darin, daß die Papier- bzw. Kartonagenzuschnitte 4 und/oder die Fußeinsätze 6 oder die Kappen 7 mit Klebemittelüberschuß mit den ihnen benachbarten Flächen bzw. Teilen der Palette verklebt sind. Nach Applikation der Papier-bzw. Kartonagenzuschnitte auf der Unterseite der Palette und gegf. an die Kufenleisten KL und ggf. auch Applikation der oben erläuterten Fußeinsätze 6 oder Kappen 7, wobei der Klebstoff satt aufgetragen wird, kann das Ganze gegf. sogar verpreßt werden, um den Klebstoff gewissermaßen mit Nachdruck in das trockene aber insoweit auch poröse und damit aufnahmefähige Pulpmaterial "einzutreiben", ganz abgesehen davon, daß ein solcher Eindringeffekt bis zu einem gewissen Grade auch von selbst erfolgt, was natürlich ebenfalls zur zusätzlichen Verfestigung der Palette beiträgt.To reinforce and the stability of the pallet in terms also a point load especially in the environment of Hollow feet 2 enhancing training also wear such in which, on the one hand, 2 corresponding but correspondingly reduced in size, separately Pulp suction-molded, pot-like foot inserts 6 arranged and these are glued to the hollow base inner walls 2 '. For this purpose, the hollow foot 2 shown on the left in FIG. 4 referred. On the other hand, a related one is possible and also for the sake of simplicity also in Fig. 4 am middle hollow foot 2 with the illustrated embodiment, in which on the outside of the hollow feet 2 corresponding, but corresponding enlarged caps, separately molded from pulp 7 are arranged, the edges with their upper edges 7 ' 3 'of the penetration recesses 3 of the paper or. Cardboard blank 4 cover and with the hollow feet 2 and Edges 3 'of the cardboard blank 4 are glued. Since the "Reinforcements", that is, paper or cardboard blanks 4 and the hollow foot reinforcements are preferably glued per se, In this regard, an advantageous further training consists in that the paper or cardboard blanks 4 and / or the Foot inserts 6 or the caps 7 with excess adhesive the adjacent areas or parts of the pallet are glued. After application of the paper or. Cardboard blanks on the bottom of the pallet and if necessary. on the KL skid strips and, if necessary, application of the above explained foot inserts 6 or caps 7, the adhesive the whole can be applied. even pressed to insist on the glue so to speak dry but also porous and therefore absorbent "Drive in" pulp material, quite apart from the fact that a such penetration effect to a certain extent also from itself takes place, which of course also for additional Consolidation of the pallet contributes.

Eine bezüglich solcher Stützeinsätze für die Hohlfüße 2 weitere Ausführungsform besteht darin, daß gemäß Fig. 5, 6 in den Hohlfüßen 2 axial senkrecht zur Tragfläche 1 und stellungsfixiert im wesentlichen zylindrische Einsätze 8 angeordnet sind, die mit ihrem oberen Rand 8'' in der Ebene der Tragfläche 1 enden. Diese Einsätze 8 sind mit Rücksicht auf Recyclebarkeit der Gesamtpalette aus entsprechend steifen Kartonagenrohrstücken gebildet. Durch die Anordnung solcher Rohrstücke in den Hohlfüßen 2 wird die Belastbarkeit der Palette ebenfalls wesentlich erhöht, da diese Rohrstücke eine Auflast direkt in die Fläche weiterleiten, auf der die Palette aufgestellt wird. Statt solcher Rohrstücke bzw. Einsätze 8 aus Kartonage kann bspw. auch Wellpappe verwendet werden, die, in Streifenform geschnitten, zu einem im wesentlichen zylindrischen Einsatz 8 zusammengerollt wird (siehe Fig. 7). Die Streifenbreite der Wellpappe entspricht dabei der erfolrderliche Höhe der Einsätze 8.One with respect to such support inserts for the hollow feet 2 another embodiment is that according to FIGS. 5, 6 in the hollow feet 2 axially perpendicular to the wing 1 and fixed in position arranged essentially cylindrical inserts 8 with their upper edge 8 '' in the plane of the Wing 1 ends. These inserts 8 are respectful of Recyclability of the entire range from appropriately rigid Cardboard tube pieces formed. By arranging such Pipe pieces in the hollow feet 2 is the resilience of Pallet also increased significantly because of these pipe pieces forward a load directly into the area on which the Pallet is set up. Instead of such pipe sections or Inserts 8 made of cardboard can also be used, for example, corrugated cardboard which, when cut into strips, become an im essential cylindrical insert 8 is rolled up (see Fig. 7). The strip width corresponds to the corrugated cardboard the successful amount of the stakes 8.

Die bei Belastung der Palette auftretenden Scherkräfte zwischen den schwach geneigt orientierten Hohlfußwänden W und sich daran horizontal anschließenden Teilen der eigentlichen Tragfläche 1 werden durch solche Rohrstrücke bzw. Einsätze 8 ganz wesentlich reduziert. Bezüglich der Stellungsfixierung dieser Rohrstücke gibt es unterschiedliche Ausführungsmöglichkeiten. So können gemäß Fig. 5 die Böden 2' der Hohlfüße 2 mit einer dem Innenquerschnitt der Einsätze 8 entsprechenden Aufwölbung 2'' versehen sein, und außerdem ist es möglich, alternativ dazu oder in Kombination damit in den Wänden W der Hohlfüße 2 nach innen weisende Rippen 9 auszuformen, die an den rohrförmigen Einsätzen 8 anliegen. Dieses Anliegen der Rippen 9 an den Einsätzen 8 ist in Fig. 6 verdeutlicht.The shear forces occurring when the pallet is loaded the weakly inclined hollow base walls W and horizontally adjoining parts of the actual Wing 1 are formed by such pipe sections or inserts 8 significantly reduced. Regarding the position fixation there are different design options for these pipe sections. 5, the bottoms 2 'of the hollow feet 2 with an inner cross section of the inserts 8 corresponding bulge 2 '', and is also it is possible, alternatively or in combination with it in the To form walls W of the hollow feet 2 inwardly pointing ribs 9, which abut the tubular inserts 8. This abutment of the ribs 9 on the inserts 8 is shown in FIG. 6 clarifies.

Abgesehen davon, daß die Einsätze 8 zwischen die Rippen 9 bei entsprechender Bemessung und mit Rücksicht darauf, daß die Hohlfußwände W eine gewisse Elastizität haben, mit Preßsitz eingesetzt werden können, werden die Einsätze 8 mit den an ihnen anliegenden Innenflächen der Hohlfüße 2 bevorzugt verklebt, d.h., mit den Rippen 9 und/oder den Seitenflanken 10 der Aufwölbungen 2''.Apart from the fact that the inserts 8 between the ribs 9 at appropriate assessment and taking into account that the Hollow foot walls W have a certain elasticity, with a press fit can be used, the inserts 8 with the preferably glued to the inner surfaces of the hollow feet 2, i.e. with the ribs 9 and / or the side flanks 10 the bulges 2 ''.

Vorteilhaft werden ferner derartige Paletten mit sogenannten Kufenleisten KL versehen, die gewissermaßen indirekt ebenfalls eine Durchbiegungsversteifung darstellen, da die Hohlfüße 2, mit ihren unteren Enden fest mit den Kufenleisten KL verbunden, an einer belastungsbedingten Spreizung gehindert werden. Um leicht zu bleiben und auch recyclebar zu sein, sind die Kufenleisten KL (siehe Fig. 2 bis 4) ebenfalls im Saugformverfahren ausgeformt und zur Palette hin mit Rippenprofilierungen 11 und mit Aufnahmeausnehmungen 12 für die Hohlfußenden versehen, wobei mindestens palettenseitig auf den verrippten Bereichen 5 zwischen den Aufnahmeausnehmungen 12 Papier- bzw. Kartonagenzuschnitte 4' angeordnet und diese mit den Kufenleisten KL verklebt sind. Unter "mindestens palettenseitig" ist dabei zu verstehen, daß solche Papier-bzw. Kartonagenzuschnitte 4' auch bodenseitig an den Kufenleisten KL entsprechend verklebt angeordnet sein können, was deren Verschleißfestigkeit erhöht. Solche Kufenleisten KL können im übrigen insgesamt vorteilhaft bspw. auch mit Wasserglas getränkt werden, um sie wiederstandsfähig gegen etwa vorhandene Bodennässe zu machen.Such pallets with so-called Skid rails KL provided, which to a certain extent indirectly also represent a deflection stiffening, since the Hollow feet 2, with their lower ends fixed to the skid strips KL connected to a stress-related spread be prevented. To stay light and also recyclable too be, the skid strips KL (see Fig. 2 to 4) are also molded in the suction molding process and towards the pallet with rib profiles 11 and with receiving recesses 12 provided for the hollow foot ends, at least on the pallet side on the ribbed areas 5 between the Receiving recesses 12 paper or cardboard blanks 4 ' arranged and these are glued to the skid strips KL. "At least on the pallet side" means that such paper or. Cardboard blanks 4 'also on the bottom be glued to the skid strips KL accordingly can, which increases their wear resistance. Such Skid strips KL can, for the rest, advantageously overall, for example. can also be soaked with water glass to make them resistant against any existing soil moisture.
