Nestable pallet with improved racking and conveyor performance
A nestable pallet ( 100, 200, 300, 400 ) has a deck ( 102 ) for supporting a load and a set of hollow tapered legs ( 106 ), the legs having an upper opening and an inwardly-tapered internal surface ( 108 ) for receiving part of a corresponding leg of another pallet when a plurality of similar pallets are stacked. Some of the hollow legs have a peripheral support configuration that includes a lower-leg extension ( 110 ), projecting horizontally from an inwardly-tapered portion of the leg towards an edge ( 112 ) of the pallet and an upper-leg opening ( 114 ) for receiving the lower-leg extension of another pallet when a plurality of similar pallets are stacked.
1 . A nestable pallet for supporting a load above a floor comprising:
(a) a deck having an upper surface for supporting the load, said deck having an outer perimeter; and
(b) a set of hollow legs integrally formed with said deck so as to be rigidly integrated therewith and extending downwards from said deck so as to support said deck above the floor, each of said hollow legs having an upper opening and an inwardly-tapered internal surface for receiving part of a corresponding leg of another pallet when a plurality of similar pallets are stacked, wherein a plurality of said hollow legs adjacent to said outer perimeter each includes a peripheral support configuration comprising:
(i) a lower-leg extension projecting horizontally from an inwardly-tapered portion of said leg towards an edge of the pallet corresponding to a downwards projection of said outer perimeter, and
(ii) an upper-leg lateral opening for receiving the lower-leg extension of another pallet when a plurality of similar pallets are stacked,
and wherein at least one of said hollow legs adjacent to a corner of said deck is formed with two of said peripheral support configurations with rigid lower-leg extensions extending towards two adjacent edges of the pallet.
2 . The nestable pallet of claim 1 , wherein said lower-leg extension forms part of a closed shape of a lower part of said leg.
3 . The nestable pallet of claim 1 , wherein said inwardly-tapered portion of said leg has a taper angle of at least 3 degrees, and wherein said lower-leg extension has a draft angle of no more than 2 degrees.
4 . The nestable pallet of claim 1 , wherein said outer perimeter of said deck is continuous around said deck, and wherein said lower-leg extension is sized so as to fit within said outer perimeter when a plurality of similar pallets are stacked.
5 . The nestable pallet of claim 1 , wherein said inwardly-tapered internal surface of each of said hollow legs defines a generally rectangular horizontal cross-sectional shape, and wherein at least one edge of said rectangular horizontal cross-sectional shape is interrupted by said upper-leg opening and said lower-leg extension, said lower-leg extension extending outside said rectangular horizontal cross-sectional shape.
6 . A nestable pallet for supporting a load above a floor comprising:
(a) a deck having an upper surface for supporting the load, said deck having an outer perimeter; and
(b) a set of hollow legs rigidly integrated with said deck and extending downwards from said deck so as to support said deck above the floor, each of said hollow legs having an upper opening and an inwardly-tapered internal surface for receiving part of a corresponding leg of another pallet when a plurality of similar pallets are stacked, wherein a plurality of said hollow legs adjacent to said outer perimeter each includes a peripheral support configuration comprising:
(i) a lower-leg extension projecting horizontally from an inwardly-tapered portion of said leg towards an edge of the pallet corresponding to a downwards projection of said outer perimeter, and
(ii) an upper-leg opening for receiving the lower-leg extension of another pallet when a plurality of similar pallets are stacked,
wherein said inwardly-tapered internal surface of each of said hollow legs defines a generally rectangular horizontal cross-sectional shape, and wherein at least one edge of said rectangular horizontal cross-sectional shape is interrupted by said upper-leg opening and said lower-leg extension, said lower-leg extension extending outside said rectangular horizontal cross-sectional shape.
