Definitions

• the pallet of the present invention resolves the above-stated design problems in existing pallets and provides a rugged, relatively lightweight pallet utilizing two runners rather than three.
• the pallet has been tested by an independent laboratory and shown to be capable of supporting 72,000 pounds (32,725 Kg), and by virtue of the careful positioning of the two support runners and spacer stanchions, weight distribution is such that the problem of the parting of the unit along the longitudinal centerline is all but eliminated.

• the basic form of the pallet is shown at 20 wherein the upper and lower grid platforms are indicated at 22 and 24, respectively. These platforms are identical and in fact the top half of the skid is the mirror image of the bottom half.
• Each of the platforms is made of a continuous peripheral header beam 26 and a number of lateral stringers 28 which span between the longitudinal lengths of the header beams 26.
• the continuous peripheral beams and the stringers are both made of one inch (2.5em), tubular steel which is generally square in cross section, and all the individual lengths are welded into place to define an extremely rigid and rugged platform.
• the primary support serving to maintain the upper platform spaced from the lower platform comprises two longitudinally extended runners 30.
• These runners are also tubular steel, and in the preferred embodiment, comprise rectangular-in-cross section tubing 1 inch (2.5cm) thick, and 3 inches (7.5cm) tall.
• These runner tubes 30 are welded into position and capped at the ends with V-shaped caps 32 which finish off the ends of the runners and also act as guides for the prongs of a fork-lift, these prongs passing immediately outside of the two runners 30 so that the runners themselves act as guides.
• tubular runners 30, welded into position between the two platforms invests the unit with a great deal of strength, particularly against compression, but also against bending and twisting forces.
• a plurality of upright stanchions 34 are welded between respective portions of the peripheral beams 26.
• the stanchions define rectangles with the stringers and corresponding portions of the runners 30 and offer high resistance to bending of the edges of the pallet downward under laterally unbalanced loads.
• the corners of the header beams, indicated at 36 are arcuate in plan form and in cross section are passed between rollers to compress the sidewalls of the tube member defining these segments into a concave configuration shown in Figure 6, with the concommitant bulging of the top and bottom surfaces of the tube into a convex configuration.
• the concave-convex combination results in the increased strength and ability to resist bending of these rounded corners.
• a double-ended socket 38 is welded to each of the corners 36, as best seen in Figures 9 and 10. These sockets have flared lips 40 and are actually made in two halves which are welded to a separator plate 42.
• the frames which are engaged in these sockets are shown in Figures 11-16 at 44 and preferably comprise two identical components 46. Each of these components includes two upright posts 48 having generally V-shaped connectors 50 which have mutually embracing means at the center of the V.
• the posts themselves are preferably tapered at the bottom and the top by virtue of beveled plugs 52 and this taper, coupled with the approximately 2" diameter of the flares 40 of the sockets, conform to the standard of pallet positioning accuracy by fork-lift which is 2". Note that the upper ends of these posts 48 are free to pass into the bottom of the sockets 38 permitting the full load of the upper pallet to be directly passed down vertically to the underlying support member. This contrasts with present stacking frames in which the connectors 50 are ordinarily used to bear the full weight of the overlying pallets.
• the means joining the two components 46 of the stacking frames may be a pair of pins 54 which seat in sockets 56 alongside the pins. Note that with the pin on the left and the sockets immediately to the right, the components can be identically made and still mate properly.
• FIG. 14 through 16 A variant means of embracing the two component parts of the frame is shown in Figures 14 through 16 wherein a strap or hook 58 on each of the V-shaped components engages over the top of the other, so that the two components must be coupled in an angular or twisting fashion but are then separable when the posts are engaged in the sockets and cannot be separated until they are removed, providing an added degree of stability and securing to the unit.
• Pallets are often transported within warehouses and elsewhere on conveyor belts made of parallel rollers. Transporting the instant pallet on such a roller would cause problems due to the spaced lateral stringers which would repeatedly hang up between rollers. To avoid this problem, longitudinal filler members 60 are then welded flush with the outer surface defined by the platforms between tubing segments at the leading and trailing edge of the pallet.
• pallet extensions are shown at 62 in Figures 7 and 8. Construction of the extensions is similar to that of the rest of the pallet and comprises oval tubes 64 and stringer extensions 66.
• a lower longitudinal member 68 lifes flush against the lower platform 24 and connects to the oval beam 64 through a pair of stanchions 70 and angular supports 72.
• Three upper clamps 74 and two lower clamps 76 hold the extensions temporarily but firmly in place on one or both sides of the basic pallet a shown in Figure 7.
• the unit as shown in its several modifications and with its several component parts represents an advance in the pallet art, principally in the strength and durability of its construction, its elimination of the midline breaking problem, and the provision of runners which are two in number, rather than three, to correspond and act as guides for the prongs of a fork-lift. Additionally, this basic structure accommodates and is complemented by the strong and efficient stacking frames 44 and the lateral extensions 62 to define a simple but remarkably versatile improvement in the pallet art.
