Cl. 108-58 9 Claims ABSTRACT OF THE DISCLOSURE Disclosed is a pallet having top and bottom members connected together by means which space said members to accommodate between them lifting means. The connecting means include upright support elements, near the perimeter of the pallet, which are spaced from each other to define in all sides of the pallet entryways that admit the lifting means. These entryways are characterized by having sidewalls which intersect the perimeter of the pallet to define between each sidewall and the perimeter an acute angle ranging between about 30 and about 75 The sidewalls guide the lifting means.
THE INVENTION We have invented a pallet having about equal size, generally flat and rigid, rectangular top and bottom members connected together by means which space the top and bottom members to accommodate between them lifting means such as the forks of a lift truck. These connecting means include an upright support element near each corner of the pallet, an upright support element near the perimeter of the pallet about midway between adjacent pairs of corners, and a support element near the center of the pallet. Support elements near the perimeter of the pallet are spaced from each other to define in all sides of the pallet entryways which admit lifting means. The corner support elements and support elements between corners are characterized by having sidewalls which intersect the perimeter of the pallet to define be- I tween each sidewall and the perimeter an acute angle ranging between about 30 and about 75. Adjacent pairs of sidewalls form the entryways and also serve as guide surfaces. Thus, if the forks of a lift truck are improperly aligned as they approach the entryways, the sidewalls aligned them properly. This is the most important feature of our pallet, because it greatly facilitates handling.
Our pallet also has other important features. It can be easily and inexpensively constructed, it has strength and durability, and it permits entry of the forks of a lift truck approaching the pallet from any one of the pallets four sides. Although our pallet can be made of any material having adequate strength, we prefer using foam plastic such as polyethylene, because the pallet can then be mass produced using known molding techniques. Our design also minimizes the material required without sacrificing strength; thus material costs are reduced.

DESCRIPTION OF PREFERRED EMBODIMENTS As depicted in FIG. 1, pallet 10 of our invention has top and bottom members 12 and 14, respectively, which are about equal in size (40 in. x 48 in.). Both these members 12 and 14 are flat, rigid, and rectangular in shape. Edges 16 and 18 of bottom members 14 are chamfered to allow wheel entry of hand trucks. Slots 20' in top and bottom members 12 and 14 cut down on material cost and provide openings for securing a load to pallet 10 with ropes or the like.
As best illustrated in FIG. 2, top and bottom members 12 and 14 are connected together by connecting means which include corner support elements 23-26, side support elements 38-41, and center support element 50.
Corner support elements 23-26 intersect the pallets corners 28-31, with each of these corner support elements 23-26 having vertical sidewalls 32 and 34. Between these sidewalls 32 and 34 and the pallets perimeter 36, there is defined an acute angle of about 45 Side support elements 38-41 are near the pallets perimeter 36 about midway between adjacent pairs of corners. Each of these side support elements 38-41 includes external vertical sidewalls 42 and 44 which intersect the pallets perimeter 36. These sidewalls 42 and 44 and the perimeter 36 defined between them an acute angle which may range between 30 and however, FIG. 2 depicts the preferred angle of 60. Side support elements 38-41 also include vertical sidewalls 46 flush with perimeter 36. These sidewalls 46 connect sidewalls 42 and 44.
Because of the spatial arrangement of corner support elements 23-26 and side support elements 38-41, two entryways 48 and 49 are provided in all four sides of pallet 10. Adjacent pairs of sidewalls 32 and 42 define entryways 48, and adjacent pairs of sidewalls 34 and 44 define entryways 49. These sidewalls serve as guide means for aligning the forks of a lift truck as they approach pallet 10. Thus misaligned forks will glance off these sidewalls and be directed into entryways 48' and 49.
FIG. 4a illustrates an alternate corner support element 58 which includes a pair of plates 60 and 62 which straddle a nearby corner of pallet '10 and converge to form a V- shaped component. Each of these plates 60 and 62 has an external vertical sidewall 64 and internal vertical sidewall 66 which intersect the pallets perimeter 36. Sidewalls 64 and perimeter 36 defined between them an acute angle which may range between about 30 and 75, and as shown in FIG. 411, preferably is about 60 Sidewalls 66 and perimeter 36 define between them an obtuse angle which may range between about and 150, and as shown in FIG. 4a, preferably is about FIG. 4b illustrates another alternate corner support element 70 which includes a pair of spaced parallel plates 72 and 74 which straddle a nearby corner. Each plate has an external vertical sidewall 76 and an internal vertical sidewall 78 which intersect the pallets perimeter 36. Sidewalls 76 and perimeter 36 defined between them an acute angle which may range between about 30 and 75 and as shown in FIG. 4a, preferably is about 45 Sidewalls 78 and perimeter 36 defined between them an obtuse angle which may range between about 105 and and as shown in FIG. 411, preferably is about'135 FIG. 5a depicts an alternate side support element 80 which includes a pair of plates 82 and 84 that converge to. form a V-shaped component. The point of convergence 86 of plates 82 and 8 4 is immediately adjacent to the pallets perimeter 36. This V-shaped component has a pair of external sidewalls 88 and 90 which intersect the perimeter 36 so that between the perimeter and these sidewalls there is defined an acute angle which may range between about 30 and 75 and as depicted in FIG. 5a, preferably is about '60 FIG. 5b shows yet another alternate side support element 92 which includes a pair of spaced plates 94 and 96 that intersect the pallets perimeter 36. Each of these plates has an external vertical sidewall 98 and an internal vertical sidewall 100. Sidewalls 98 and perimeter 36 defined an acute angle which may range between 30 and 75, and as depicted in FIG. 5a preferably is about 60. Sidewalls 100 and perimeter 36 defined an obtuse angle which may range between 105 and 150, and as depicted in FIG. 5 b, preferably is about 120.
' Many diiferent combinations of the support elements shown in the figures are possible. It is not important how these support elements are combined. It is, however, important that the external sidewalls of the support elements and the perimeter of the pallet defined between them an acute angle ranging between about 30 and 75. Such sidewalls then provide guideways which facilitate the entrance of the forks of a lift truck, As previously mentioned, the pallet preferably is made by a foam plasticQThis reduces the cost and facilitates mass production of the pallet using known molding techniques.
