Definitions

  • Pallets are often used for supporting and moving various types of articles and may be constructed from many different materials including wood, metal, fiberglass, and plastic. Pallets are typically designed to be loaded and moved by forklifts, hand trucks, cranes, or other specialized handling or loading equipment and therefore are typically constructed with forklift channels through which forklift tines, pallet jacks, or hand jacks may be inserted.
  • pallets are designed to support boxes and other items with flat lower surfaces and therefore are typically constructed with relatively flat or planar upper decks.
  • pallets are also often used to support rolls of material and other items with curved lower surfaces, and such items tend to roll off flat-topped pallets.
  • some pallets are constructed with cradles or other depressions on their upper decks.
  • these cradles allow the rolls supported on the pallets to extend into and block the fork channels of the pallets such that the pallets can no longer be picked up and moved by forklifts, pallet jacks, or hand jacks without damaging the rolls.
  • Embodiments of the invention solve the above-mentioned problems and provide a distinct advance in the art of pallets. More particularly, the present invention provides a pallet that allows curved objects to be stacked thereon without the curved objects interfering with lift channels of the pallet. The pallet can also be stacked on another pallet holding curved objects without the curved objects interfering with the lift channels of either pallet.
  • An embodiment of the pallet comprises an upper deck, a lower deck opposite the upper deck, a front wall, a rear wall opposite the front wall, a first side wall, a second side wall opposite the first side wall, and a set of lift channels.
  • the upper deck includes a number of horizontally extending upper surfaces and a number of downwardly sloping walls extending from the upper surfaces.
  • the horizontally extending upper surfaces are configured to support flat objects such as boxes or other pallets.
  • the downwardly sloping walls form upper support cradles for supporting curved objects thereon.
  • the upper support cradles define lowermost apices.
  • the lower deck may include horizontally extending lower surfaces and a number of upwardly sloping walls extending from the lower surfaces.
  • the upwardly sloping walls form lower support cradles for stacking the pallet on another pallet supporting curved objects.
  • the lower support cradles define uppermost apices.
  • the curved objects could be cylindrical tanks, canisters, tubes, pipes, rolls, or any other curved objects.
  • the lift channels extend through the pallet between the front and rear walls and allow the pallet to be lifted via lifting forks of a forklift or pallet jack inserted into the lift channels.
  • the lift channels include upper walls positioned below the lowermost apices of the upper support cradles and may include lower walls positioned above the uppermost apices of the lower support cradles. In this way, curved objects positioned in the upper support cradles and curved objects positioned in the lower support cradles will not interfere with the lifting forks being inserted into the lift channels. This allows the pallet to be lifted without damaging or displacing the curved objects.
  • the pallet includes structure that permits the pallet to support curved objects while being stacked on another pallet supporting previously stacked curved objects.
  • the pallet includes upper support cradles and lower support cradles that are vertically aligned with the upper support cradles such that curved objects supported on the pallet and curved objects on which the pallet is being stacked are aligned. This allows the curved objects to be stacked, lifted, and moved as a multi-layered unit.
  • the upper support cradles may have the same size and shape and the lower support cradles may have the same size and shape.
  • the upper support cradles may have the same size and shape as the lower support cradles.
  • FIG. 1 is a perspective view of a pallet constructed in accordance with an embodiment of the invention
  • FIG. 2 is a bottom perspective view of the pallet of FIG. 1 ;
  • FIG. 3 is a front elevation view of the pallet of FIG. 1 ;
  • FIG. 4 is a side elevation view of the pallet of FIG. 1 ;
  • FIG. 5 is a perspective view of two pallets and two sets of large curved objects forming a stacked column.

Abstract

L'invention concerne une palette qui comprend un corps principal comportant un plateau supérieur, un plateau inférieur et un ensemble de canaux de levage. Le plateau supérieur comprend des surfaces supérieures s'étendant horizontalement, et des parois inclinées vers le bas s'étendant à partir des surfaces supérieures. Les surfaces supérieures s'étendant horizontalement sont conçues pour recevoir des objets plats. Les parois supérieures inclinées vers le bas forment des berceaux de support supérieurs sur lesquels des objets courbés orientés horizontalement sont destinés à être reçus. Le plateau inférieur comprend des surfaces inférieures s'étendant horizontalement, et des parois inclinées vers le haut s'étendant à partir des surfaces inférieures. Les surfaces inférieures s'étendant horizontalement sont conçues pour être positionnées sur des objets plats. Les parois inclinées vers le haut forment des berceaux de support inférieurs destinés à positionner la palette sur des objets courbés s'étendant horizontalement. Les canaux de levage sont espacés verticalement par rapport aux berceaux de support supérieurs et aux berceaux de support inférieurs, de sorte que les objets courbés positionnés au-dessus et au-dessous de la palette n'interfèrent pas avec des fourches de levage insérées dans les canaux de levage.
