The sheet is provided along the bend lines and in accordance with the configuration of the profiled grooves with rows of recesses having associated slots to accommodate folding of the profiled sheet into the hollow girders.

Description

Die Erfindung betrifft eine Palette aus wellenartig abgekantetem Blech mit im wesentlichen rechteckigem oder trapezförmigem Querschnitt der Wellen, die mit senkrecht zur Stand- und Ladefläche angeordneten Stützwänden kastenartige Hohlträger bildet.The invention relates to a pallet made of corrugated sheet metal with a substantially rectangular or trapezoidal cross section of the shafts, which forms box-like hollow beams with support walls arranged perpendicular to the standing and loading area.

Eine derartige Palette ist aus der US-A-2 306 752 bekannt. Diese Palette besteht aus mehreren wellenartig profilierten Bodenblechen und Deckblechen, welche an ihren Enden und in der Mitte von besonderen, profilierten Stützwänden in Abstand gehalten sind. Diese Stützwände haben kurze abgebogene Schenkel und greifen in die Profilierung der Deck- und Bodenbleche ein, mit denen sie durch Punktschweissung fest verbunden sind. Die Deck- und Bodenbleche, welche die Lade- und Standfläche der Palette bilden, ergeben mit den senkrecht hierzu angeordneten Stützwänden kastenartige Hohlträger, die sich über die gesamte Breite der Palette erstrecken.Such a pallet is known from US-A-2 306 752. This range consists of several wave-like profiled floor plates and cover plates, which are kept at their ends and in the middle of special, profiled supporting walls. These retaining walls have short bent legs and engage in the profiling of the top and bottom plates, with which they are firmly connected by spot welding. The top and bottom plates, which form the loading and standing surface of the pallet, result in box-like hollow beams with the support walls arranged perpendicularly thereto, which extend over the entire width of the pallet.

Derartige Paletten erfordern einen grossen Werkstoffbedarf und sind in der Herstellung sehr aufwendig, da sie aus vielen miteinander durch Schweissung zu verbindenden Einzelteilen bestehen.Such pallets require a large amount of material and are very expensive to manufacture, since they consist of many individual parts to be joined together by welding.

Die Erfindung hat sich die Aufgabe gestellt, eine Palette mit kastenartigen Hohlträgern aus nur einem wellenartig abgekantetem Blech herzustellen, die bei besonders einfacher Herstellung und geringem Werkstoffbedarf eine hohe Tragfestigkeit hat und besonders vorteilhafte Lade- und Standflächen aufweist. Erfindungsgemäss besteht die Palette aus einem einzigen Blech, welches beidseitig durch je drei quer zu den Profilnuten des Bleches verlaufenden Biegekanten zu jeweils einem Hohlträger abgekantet ist, der aus Teilen der Ladefläche, zwei senkrechten Stützwänden und einer Standfläche besteht, wobei zur Ermöglichung der Abkantung im Bereich der Wellentäler der Stützwände sich über die Breite der Wellentäler erstreckende einseitig an die Biegekanten anschliessende Aussparungen vorgesehen sind, von denen längs der Biegekanten verlaufende Schlitze ausgehen, die sich über die Wellenseitenwände erstrecken.The invention has set itself the task of producing a pallet with box-like hollow beams from only a wave-like folded sheet, which has a particularly high load-bearing capacity with particularly simple manufacture and low material requirements and has particularly advantageous loading and standing surfaces. According to the invention, the pallet consists of a single sheet, which is bent on both sides by three bending edges running transversely to the profile grooves of the sheet to form a hollow beam, which consists of parts of the loading area, two vertical support walls and a standing area, with the possibility of bending in the area the troughs of the supporting walls extending over the width of the troughs are provided on one side adjoining the bending edges, from which slots extending along the bending edges extend and extend over the side walls of the shaft.

Weitere vorteilhafte Ausbildungen sind in den abhängigen Ansprüchen beschrieben.Further advantageous developments are described in the dependent claims.

Die erfindungsgemässen Paletten können von Gabelstaplern oder ähnlichen Einrichtungen transportiert werden und sind leer ineinander stapelbar.The pallets according to the invention can be transported by forklifts or similar devices and can be stacked empty one inside the other.

Die Palette 1 besteht aus einem einzigen recht eckigen Blech 2, z.B. aus Stahl mit querlaufenden U-förmigen Nuten 3. Die Fig. 1 zeigt das Ausgangsblech 2 vor Profilierung und vor der Abkantung der Randzonen.The pallet 1 consists of a single rectangular sheet 2, e.g. made of steel with transverse U-shaped grooves 3. FIG. 1 shows the starting plate 2 before profiling and before the edge zones are folded.

Die beiderseitigen Randzonen 4,5,6 sind - wie Fig. 2 zeigt - unter Bildung der Kanten 7,8,9 dreimal um je 90° nach innen gekantet. Dadurch wird beiderseitig ein geschlossener längslaufender, kastenartiger Hohlträger 10 und 11 gebildet, in dem die Tragarme eines Gabelstaplers eingreifen können. Hierbei bilden die Teile 4 und 6 Innen- und Aussenstützen bzw. Pfosten. Die Teile 4 sind somit die inneren Stützwände und die Teile 6 die äusseren Stützwände der beiden Hohlträger 10 und 11. Die Teile 4 und 6 sind senkrecht zur Standfläche 5 und zur Ladefläche 12 angeordnet. Die Gesamtheit der Teile 5 der Profilierung bilden beiderseitig die Standfläche. Die gesamte verbleibende Oberfläche 12 der Profilierung ist die Ladefläche. Diese kann auch mit einer zusätzlichen Feinprofilierung versehen sein , wodurch die Standfestigkeit noch weiter verbessert wird.The edge zones 4, 5, 6 on both sides are - as shown in FIG. 2 - edged inwards to form the edges 7,8,9 three times by 90 ° each. This forms a closed, longitudinal, box-like hollow support 10 and 11 on both sides, in which the support arms of a forklift can engage. The parts 4 and 6 form inner and outer supports or posts. The parts 4 are thus the inner support walls and the parts 6 the outer support walls of the two hollow beams 10 and 11. The parts 4 and 6 are arranged perpendicular to the standing surface 5 and the loading surface 12. The entirety of the parts 5 of the profiling form the base on both sides. The entire remaining surface 12 of the profiling is the loading area. This can also be provided with an additional fine profile, which further improves the stability.

Die Bemessung der Breite der beiderseitigen Hohlträger 10 und 11 ist je '/3 der Gesamtbreite der Ladefläche 12.The dimensioning of the width of the hollow beams 10 and 11 on both sides is in each case 3/4 of the total width of the loading area 12.

Es können auch trapezförmige Nuten vorgesehen werden, deren Stege einen steilen Winkel, z.B. 80°, aufweisen.Trapezoidal grooves can also be provided, the webs of which have a steep angle, e.g. 80 °.

Gemäss den Figuren 1, 6 bis 8 und 9, 10 ist zur Ermöglichung der erfindungsgemässen Abkantung der Randzonen 4, 5, 6 quer zu den U-förmigen Profilnuten 3 und zur Bildung der Hohlträger 10 und 11 das Profilblech an den herzustellenden Biegekanten 7, 8, 9 in der Breite und Höhe des U-Profils 3 mit Reihen von rechteckigen Aussparungen 13 versehen.According to FIGS. 1, 6 to 8 and 9, 10, in order to enable the edge zones 4, 5, 6 to be bent according to the invention transversely to the U-shaped profile grooves 3 and to form the hollow beams 10 and 11, the profiled sheet on the bending edges 7, 8 to be produced , 9 provided in the width and height of the U-section 3 with rows of rectangular recesses 13.

Die an den Biegekanten 8, 9 verlaufenden Längsseiten 14 der Aussparung 13 sind gemäss Fig. 1 und 6 beiderseitig durch Schlitze 15, 16 entsprechend der Form und der Steghöhe der Profilierung verlängert. Dadurch wird es möglich, dass beim Abkanten der von den Schlitzen 15,16 gebildeten Profilstege 17 der Biegekanten 8 und 9 sich über die Stege der Pfosten oder Stützwände 6 und 4 legen (siehe Fig. 8). Fig. 6 zeigt das Blech 2 in der Ausgangsform, während es in Fig. 7 mit Profilierung dargestellt ist. Die strichlierte Linie zeigt die Blechstärke.The longitudinal sides 14 of the recess 13 running on the bending edges 8, 9 are extended on both sides according to FIGS. 1 and 6 by slots 15, 16 in accordance with the shape and the web height of the profiling. This makes it possible that when the profile webs 17 of the bending edges 8 and 9 formed by the slots 15, 16 are folded over the webs of the posts or supporting walls 6 and 4 (see FIG. 8). Fig. 6 shows the sheet 2 in the initial form, while it is shown in Fig. 7 with profiling. The dashed line shows the sheet thickness.

Wie die Figur 6 zeigt, bleibt zwischen den Aussparungen 13 der Steg 27 stehen (siehe auch Figur 8), der eine derartige Abmessung aufweist, dass sich die einander gegenüberliegenden Wellentäler 3 der Ladefläche 12 und der Standfläche 5 auf diesem Steg 27 abstützen. Der Steg 27 ist auch mit dem gleichen Bezugszeichen in die Figuren 1,7,9, 10, 11 und 12 eingezeichnet.As shown in FIG. 6, the web 27 remains between the cutouts 13 (see also FIG. 8), which has a dimension such that the mutually opposite corrugations ler 3 of the loading surface 12 and the base 5 support on this web 27. The web 27 is also shown in FIGS. 1, 7, 9, 10, 11 and 12 with the same reference number.

In den Figuren 9 und 10 ist ein weiteres Ausführungsbeispiel dargestellt, bei dem die Aussparungen 13' an einer Seite oben und unten mit je 2 Schlitzen 18, 19 versehen sind, so dass Lappen 20 und 21 umgekantet werden, die eine weitere Versteifung ergeben.A further exemplary embodiment is shown in FIGS. 9 and 10, in which the cutouts 13 'are provided on each side with two slots 18, 19 at the top and bottom, so that tabs 20 and 21 are folded over, which result in further stiffening.

In den Fig. 11 und 12 ist eine Aussparung 13" in Nutbreite vorgesehen, die beiderseitig eine dachförmige Ausbildung 22, 23 haben. Dadurch ergibt sich der für die Stosskanten 22, 23 erforderliche Anschlagwinkel, da die dachförmigen Aussparungen 22, 23 auf Gehrung geschnitten sind. Auch wird durch die Umlappungen eine höhere Festigkeit erzielt.11 and 12, a recess 13 "in groove width is provided which has a roof-shaped configuration 22, 23 on both sides. This results in the stop angle required for the abutting edges 22, 23, since the roof-shaped recesses 22, 23 are mitred The folds also increase the strength.

Die Innenstützen 4 können - wie Fig. 13 zeigt - auch mit einem umgebogenen Lappen 25 durch eine Aussparung 26 im Nutboden 3 befestigt sein.As shown in FIG. 13, the inner supports 4 can also be fastened with a bent tab 25 through a recess 26 in the groove bottom 3.

Claims (6)

1. A pallet made of corrugated sheet metal, the corrugation being of substantially rectangular or trapezoidal cross-section, with supporting walls, disposed perpendicularly to the base and loading surface, forming box-like hollow girders, characterised in that the pallet consists of a single metal sheet (2) which at each side is bent along three bending edges (7, 8, 9), extending transversely to the profile grooves (3) of the metal sheet (2), into a hollow girder (10, 11) composed of parts of the loading surface (12), two perpendicular supporting walls (4, 6) and a base surface (5), and that, to enable bending in the region of the troughs in the corrugations of the supporting walls (4, 6), there are provided notches (13, 13', 13") which extend over the width of the troughs in the corrugations, alongside the bending edges (7, 8, 9) and from which open slits (15, 16, 18, 22, 23) which extend along the bending edges and over the side walls (17) of the corrugations.
2. A pallet as claimed in Claim 1, characterised in that the notches (13, 13', 13") are rectangular and a web (27), left in a supporting wall between each two notches (13, 13', 13"), has such dimensions that the opposite troughs (3) of the corrugations of the loading surface (12) and of the base surface (5) are supported on this part.
3. A pallet as claimed in Claim 1 or 2, characterised in that the slits are extended into mitres (22, 23) in order to support the side walls (17) of the corrugations.
4. A pallet as claimed in one of the Claims 1 to 3, characterised in that ends of the troughs (3) of the corrugations of the loading surface (12) and of the base surface (5) adjacent to the bending edges (7, 8, 9) are formed into tongues (20) by slits (19) extending along the edges of the corrugations in the troughs of the corrugations, which tongues are bent inwards parallel to the supporting walls (6).
5. A pallet as claimed in one of the Claims 1 to 4, characterised in that disposed at the free edges of the inner supporting walls (4) are tongues (25) which engage through slots (26) in the troughs of the corrugations of the loading surface (12) and are bent over.
6. A pallet as claimed in Claims 1 to 5, characterised in that the hollow girders (10, 11) each occupy '/3 rd of the total width of the loading surface (12).
