Pallet having great dimensional stability and load- bearing capacity

Abstract

The invention relates to a pallet which is provided with great dimensional stability and load-bearing capacity and is used for storing and transporting all types of goods. The invention is characterized in that the plastic parts of the pallet comprise reinforcement elements which extend below the base plate of the pallet, in the region of the legs and/or within the base plate of the pallet.

1 . A pallet having high dimensional stability and load-bearing capacity for storing and transporting goods, said pallet being predominantly made of plastic, having a base plate of approximately rectangular format, having a top side of the base plate for reception of goods to be stored or transported, having a bottom side of the base plate with feet for depositing the pallet on a rack, having feet of a rectangular cross section which tapers from the base plate in a direction of a bottom side of the feet, and having a feet height such that a transport means or a lifting means can be guided under the pallet, wherein plastics parts of the pallet contain reinforcing elements, which extend beneath the base plate of the pallet in a region of the feet and/or within the base plate of the pallet. 
   
   
       2 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 1 , wherein the feet are arranged in rows extending parallel to a longitudinal side or end face of the base plate wherein, in the bottom side of the feet, grooves are formed, which extend in a longitudinal direction of the feet and thus also parallel to one side of the base plate, wherein the grooves in the bottom sides of the feet arranged contiguously in a row are mutually aligned, and wherein the grooves are adapted to receive reinforcing elements as foot rails, which connect at least  2  adjoining feet on their bottom sides. 
   
   
       3 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 2 , wherein in the bottom side of the feet, 2 grooves are respectively formed, which run parallel, and foot rails inserted in these grooves have a U-shaped cross section. 
   
   
       4 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 3 , wherein the U-shaped foot rails have on their side arms spring elements, with which stringers can be fixedly, yet detachably fastened in the feet. 
   
   
       5 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 1 , wherein the reinforcing elements within the base plate of the pallet comprise longitudinal struts, running parallel to a longitudinal side of the pallet, and transverse struts, running parallel to a transverse side of the pallet, and the longitudinal and transverse struts are connected to one another, so that a network structure is formed, nodes of the network structure in the base plate of the pallet being located in a region above the feet. 
   
   
       6 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 5 , wherein the reinforcing elements, as foot rails, connect the feet to one another on their bottom sides, the longitudinal and transverse struts, from the network nodes, are connected by further reinforcing elements, as webs, to the foot rails, and the webs run perpendicular from the network nodes through the feet to the foot rails, whereby a three-dimensional lattice structure of the reinforcing elements, formed by the longitudinal and transverse struts and foot rails and webs, is formed. 
   
   
       7 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 6 , wherein the longitudinal and transverse struts and the foot rails have a U-shaped cross section, and the longitudinal and transverse struts and the webs have cutouts for a positive engagement with the plastic of the pallet and for weight reduction purposes. 
   
   
       8 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 7 , wherein the reinforcing elements comprise steel plate and contain cutouts, the size of which amounts to up to 80% of the material height or web height. 
   
   
       9 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 2  wherein the foot rails run respectively parallel to longitudinal struts present in the base plate, and parallel to the longitudinal side of the pallet, and have a constant cross section over their entire length. 
   
   
       10 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 2 , wherein the foot rails run respectively parallel to longitudinal struts present in the base plate, and parallel to the longitudinal side of the pallet, and wherein in an interspace between the feet a region of reduced cross section, is present. 
   
   
       11 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 3 , wherein a side of the U-shaped foot rails which points to an outer side of the base plate has an extension, which, in vertical extent, extends to the top side of the base plate, so that a lateral protection for the feet and the base plate is formed, openings for transport means or lifting means remaining between the feet in region of the extension. 
   
   
       12 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 2 , wherein the top side of the base plate has recesses, which, in size and position, correspond to bottom sides of the feet of the pallet, and wherein, in the top side of the base plate, channels are additionally present, which run between said recesses and which correspond in size and position to the foot rails inserted in the bottom side of the feet. 
   
   
       13 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 1 , wherein the top side of the base plate has, on outer sides, an outer edge. 
   
   
       14 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 13 , wherein an area within the outer edge is sized such that the feet of an identical pallet are accommodated therein. 
   
   
       15 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 1 , further comprising, for narrower end faces of the pallet, protective caps of metal or plastic to protect the base plate and the feet. 
   
   
       16 . The pallet having high dimensional stability and load-bearing capacity for storing and transporting goods as claimed in  claim 1 , wherein the plastic for the pallet comprises Styropor.
