Abstract

A pallet (1) made of plastic or other materials is provided with a plurality of hollow feet (2, 3, 4, 5, 6, 7, and 8) at its underside (10). These are obtained by depressing the pallet material. At least one of these feet-foot (8)-has a length (L') substantially corresponding to the length (L)-or width (B)-of the pallet. This foot (8) contains at least two inner comparatively wide support parts (13, 14, 15), arranged in series and projecting from the bottom part (16) of the foot (8). In this way, according to fire tests-where several identical pallets (1) filled with goods were stacked on top of each other-each pallet (1) has a unique ability to extinguish flames generated in goods on the pallet located directly below the pallet in question, and moreover, the pallet also shows considerable dimensional stability. This makes the pallet (1) particularly suitable for transport on transport means, optionally roller conveyors which cause many bumps.

Titel: LastpalleTitle: Cargo pallet

Opfindelsen angår en lastpalle af plast eller andre materialer og af den art, som 5 ved sin underside har et antal hule fødder, som er fremkommet ved nedtrykning af pallemateriale.The invention relates to a pallet of plastic or other materials and of the kind which has at its underside a number of hollow feet which are obtained by depressing pallet material.

Fra EP offentliggørelsesskrift nr. 0725010 A1 kendes en støbt lastpalle af plast, og som ved sin underside har et antal hule fødder, der hver er udformet med en 10 hul understøtningsdel, der rager op fra bunddelen i foden. Denne lastpalle er ikke egnet tii at kvæle eller hæmme en eventuel ild i nogle varer, der står på en underliggende lastpalle. Dette fordi den betragtede lastpalles fødder er forholdsvis små.EP Publication No. 0725010 A1 discloses a molded plastic pallet, which at its bottom has a number of hollow feet, each formed with a 10 hollow support part which protrudes from the bottom part of the foot. This pallet is not suitable for suffocating or inhibiting any fire in some items that are on an underlying pallet. This is because the feet of the pallet considered are relatively small.

15 Fra US offentliggørelsesskrift nr. 20020017225 A1 kendes en støbt lastpalle af plast, og som ved sin underside omfatter et antal hule fødder, der hver er udformet med en hul understøtningsdel. Ej heller denne lastpalle er særligt egnet til at kvæle eller hæmme en eventuel ild i nogle varer, der måtte stå på en underliggende lastpalie. Dette fordi der under pallen ikke findes noget effektivt 20 middel til at begrænse en eventuel brand.US Patent Publication No. 20020017225 A1 discloses a molded plastic pallet, which at its underside comprises a plurality of hollow feet, each formed with a hollow support member. Nor is this pallet particularly suited to stifle or inhibit any fire in some goods that may be left on an underlying cargo pallet. This is because under the pallet there is no effective means of limiting any fire.

Det er formålet med opfindelsen at anvise en lastpalle af den indledningsvis nævnte art, og som i tilfælde af brand bedre end kendt kan medvirke til at kvæle eller hæmme ild på en underliggende palle og dermed reducere risikoen for at 25 ilden spredes. Desuden må lastpallen være passende fleksibel og egent til transport på alle slags transportører, især rullebaner.SUMMARY OF THE INVENTION It is an object of the invention to provide a pallet of the kind mentioned above, which, in the event of a fire, can better than suffocate or curb fire on an underlying pallet, thus reducing the risk of the fire spreading. In addition, the pallet must be suitably flexible and suitable for transport on all types of conveyors, especially runways.

Lastpallen ifølge opfindelsen er ejendommelig ved, at mindst én af de nævnte fødder - hovedfoden - har en længde i hovedsagen svarende til længden eller 30 bredden af lastpallen, og at hovedfoden indeholder mindst to efter hinanden anbragte indre og forholdsvis brede, fortrinsvis hule i og for sig kendte understøtningsdele, der rager op fra bunddelen i hovedfoden, og hvor der inden i den enkelte understøtningsdel findes mindst to, fortrinsvis tre støtteribber. Herved 2 DK 176570 B1 opnås ifølge brandforsøg - når flere med varer fyldte lastpaller af denne konstruktion er stablet oven på hinanden - at den enkelte lastpalle vil have en særlig evne til at kvæle eller hæmme flammer, som måtte opstå i varer på den lastpalle, som befinder sig lige under den betragtede lastpalle. Dette især på grund 5 af hovedfoden. Hertil kommer, at lastpallen udviser en betydelig formstabilitet og er særlig egnet til transport af varer på transportører, eventuelt rullebaner med mange bump.The pallet according to the invention is characterized in that at least one of said feet - the main foot - has a length substantially equal to the length or width of the pallet, and that the main foot contains at least two consecutive inner and relatively wide, preferably hollow in and for are known support parts which project from the bottom part of the main foot and where there are at least two, preferably three support ribs within the individual support part. Hereby 2 DK 176570 B1 is obtained according to fire experiments - when several goods pallets of this construction are stacked on top of each other - that the individual pallets will have a special ability to suffocate or inhibit flames which may arise in goods on the pallet which is just below the considered pallet. This especially because of the 5 foot. In addition, the pallet exhibits considerable shape stability and is particularly suitable for transporting goods on conveyors, possibly many bump runways.

Det kan ifølge opfindelsen - når der mellem væggen i hovedfoden og væggen i 10 den enkelte understøtningsdel findes mindst to ribber, fortrinsvis fire - gælde, at den enkelte ribbe haren tilnærmelsesvis U-formetfacon. Derved opnås en særlig stabilisering af understøtningsdelen i forhold til hovedfodens væg og dermed i forhold til resten af lastpallen, idet de nævnte ribber så at sige "tøjrer" understøtningsdelen.According to the invention, when at least two ribs, preferably four, exist between the wall of the main foot and the wall of the individual support part, the individual ribs have an approximately U-shaped shape. Thereby, a special stabilization of the support part is achieved in relation to the wall of the main foot and thus in relation to the rest of the pallet, the said ribs, so to speak, "tethering" the support part.

Ifølge opfindelsen kan den enkelte fod have en bredde, som er 0,10-0,56 gange fodens længde. Derved opnås en særlig hensigtsmæssig udformning af lastpallen.According to the invention, the individual foot may have a width which is 0.10-0.56 times the foot length. In this way, a particularly suitable design of the pallet is obtained.

20 Desuden kan ifølge opfindelsen hovedfoden være anbragt i hovedsagen på midten af pallen set i retning af pallens længderetning, henholdsvis bredderetning. Herved opnås, at især lastpallens midterparti bliver særlig formstabilt.In addition, according to the invention, the main foot may be disposed substantially on the center of the pallet in the direction of the longitudinal direction and the width direction, respectively. This results in that the center portion of the pallet in particular becomes particularly stable.

Fremdeles kan der ifølge opfindelsen i sidevæggen af hovedfoden på steder, 25 som befinder sig mellem understøtningsdelene, være tildannet aflange huller, hvorved der opnås en vis materialebesparelse.Still, according to the invention, in the sidewall of the main foot in places located between the support members, elongated holes may be formed, thus obtaining some material saving.

Fremdeles kan ifølge opfindelsen lastpailen være fremstillet af forskellige materialer, fortrinsvis plast, især plast indeholdende træfibre, f.eks. 40-60 vægt%, 30 især 45-55 vægt% plast og resten træfibre. Dette materiale er særlig hensigtsmæssigt, fordi det har god styrke og har ret svært ved at brænde.Still, according to the invention, the cargo pile may be made of various materials, preferably plastics, especially plastics containing wood fibers, e.g. 40-60% by weight, 30 in particular 45-55% by weight plastic and the rest wood fibers. This material is particularly suitable because it has good strength and is quite difficult to burn.

Ifølge opfindelsen kan hovedfodens midterste understøtningsdel set i vandret tværsnit have et areal, som er mindre end ca. 35% af arealet af det vandrette tværsnit i den understøtningsdel, der har størst vandret tværsnit. Denne udførelsesform har vist sig særlig hensigtsmæssig.According to the invention, the middle support portion of the main foot, seen in horizontal cross-section, may have an area of less than approx. 35% of the area of the horizontal cross-section of the support portion having the largest horizontal cross-section. This embodiment has proved particularly convenient.

Endvidere kan ifølge opfindelsen hovedfoden have en bredde β på 0,10-0,25, fortrinsvis ca. 0,2 gange lastpallens bredde B, hvorhos fødderne (dvs. yderfødderne) uden for hovedfoden kan have en bredde b på 0,10-0,15, fortrinsvis ca.Furthermore, according to the invention, the main foot may have a width β of 0.10-0.25, preferably approx. 0.2 times the width of the pallet B, where the feet (ie the outer feet) outside the main foot can have a width b of 0.10-0.15, preferably approx.

0,13 gange lastpallens bredde B. Dette har vist sig at give lastpallen en pas-10 sende stivhed.0.13 times the width of the pallet B. This has been found to give the pallet a suitable stiffness.

Ifølge opfindelsen kan hovedfoden indeholde to understøtningsdele, hvis længde Γ hver er 0,10-0,25, fortrinsvis ca. 0,20 gange hovedfodens længde L’, hvorhos fødderne (yderfødderne) uden for hovedfoden hver kan have en længde I 15 på 0,10-0,30, fortrinsvis ca. 0,25 gange lastpallens længde L. Herved opnås, at lastpallen især i midterområdet vil udvise en betydelig stivhed.According to the invention, the main foot may contain two support parts, the length of which Γ each is 0.10-0.25, preferably approx. 0.20 times the length of the main foot L ', wherein the feet (outer feet) outside the main foot can each have a length I 15 of 0.10-0.30, preferably approx. 0.25 times the length of the pallet L. This results in that the pallet will exhibit a considerable stiffness especially in the middle area.

Endelig kan ifølge opfindelsen højden h' af lastpallens fødder være op til ca.Finally, according to the invention, the height h 'of the pallet feet may be up to approx.

0,13 gange lastpallens længde L, hvorved opnås, at lastpallen bliver forholdsvis 20 let at flytte ved hjælp af en gaffeltruck, idet man så forholdsvis let kan få gaffeltruckens arme ind under lastpallen; men disse arme må altid føres ind under gaffeltrucken, idet de er parallelle med hovedfoden, idet der er placeret en arm på hver side af hovedfoden.0.13 times the length of the pallet L, whereby the pallet becomes relatively easy to move by means of a forklift, so that the arms of the forklift can be relatively easily retracted under the pallet; but these arms must always be brought under the forklift, being parallel to the main foot, with an arm positioned on each side of the main foot.
