DETAILED DESCRIPTION

[0042] While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.

[0043] FIGS. 1-5 show two product transfer systems 10 in accordance with an aspect of the present invention, on the tines of a fork lift 12 (illustrated schematically). Each product transfer system 10 includes a first base member in the form of a small format pallet 14 and second base member, also in the form of a small format pallet 14, positioned side by side, with each of the pallets 14 supporting a first sleeve 16 and a second sleeve 16, respectively. Each sleeve 16 includes a back wall 18, a first flap or side wall 20 extending perpendicular from one side of the back wall 18 and a second flap or side wall 22 extending perpendicular from a second side of the back wall 18. The sleeves 16 are positioned on the two pallets 14 facing opposite directions, such that the back walls 18 are next to each other, and the respective side walls 20, 22 are extending in opposite directions.

[0044] The two pallets 14 and sleeves 16 of each product transfer system 10 are coupled to each other by a first connector in the form of a first bar 24 connected to the top edges of the first side wall 20 of the first sleeve 16 and the second side wall 22 of the second sleeve 16, and a second connector in the form of a second bar 24 connected to the top edges of the second side wall 22 of the first sleeve 16 and the first side wall 20 of the second sleeve 16.

[0045] As shown in FIG. 8, each bar 24 has a horizontal top segment 26, a downwardly extending, vertical first segment 28 perpendicular to and on one side of the horizontal segment 26 and a downwardly extending, vertical second segment 30 perpendicular to and on an opposing side of the horizontal segment 26. The top segment 26, first segment 28 and second segment 30 form an inverted, generally squared off U-shape, dimensioned to snuggly fit over the top edges of the sleeves 16. The first and second segments 28, 30 include a central opening or cut-away 32 to accommodate the back walls 18 of the sleeves 16. Additionally, the top segment 26 includes a first opening 34 at one end and a second opening 36 at a second end.

[0046] Both the first side wall 20 and the second side wall 22 included an embedded rod 36 at an end of the side wall remote from the back wall 18. The rod includes a portion extending upward above the top edge of the side wall 20, 22. The first and second openings 32, 34 on the bar 24 are positioned to fit over the extending portions of the rods 36 to help secure the bar 24 to the two sleeves 16. FIG. 7 shows one of the bars 24 positioned above one of the product transfer systems 10 in a position to be lowered over the extending portions of the rods 36. In the present arrangement, the bar 24 can be quickly placed on or removed from the system 10.

[0047] The pallets 14, several of which are shown without the sleeve in FIG. 6, include a support surface 38 and a plurality of legs 40 extending downward from the support surface 38. A wall 42 extends around the periphery of the support surface 38 and is separated from the support surface 38 by a well or channel 44. The side walls 20, 22 and back wall 18 of the sleeve 16 can be positioned in the channel 44.

[0048] As shown in FIG. 5, the pallets 14 are supported on the tines 46 of the forklift 12. The forklift also includes wheels 50 (again, shown schematically) for moving the systems 10. As also illustrated, the pallets 14 can include a plurality of ribs 48 that extend downward from a lower surface of the support surface 38.

[0049] The pallets 14 are small format and have a footprint of 2448 inches. Two of the pallets 14, positioned side by side as shown in the Figures, have a footprint slightly greater than a standard 4048 inch pallet. The sleeve has a height of 65 inches.

[0050] While the rods 36 are embedded at an end of the side walls 20, 22, additional rods can be utilized at other locations (or instead of at the ends). Alternatively, the sleeves 16 can be provided with just the extensions (above the top edges) or other similar structure for securing the bars to the sleeve. Alternatively or in addition, structures connecting the back walls 18 to each other can be utilized.

[0051] Each sleeve 16 can be provided with netting 58 (or other similar structure) that can extend across the open side of the sleeve 16 (as shown in FIGS. 9 and 10), to enclose any products stored on the pallet 14. Additionally, each sleeve 16 can be fitted with a top cap 52 (shown in FIG. 10).

[0052] The netting 58 can be utilized as a connector in an alternative product transfer system 54 illustrated in FIGS. 11 and 12. In this aspect of the invention, the netting 58 is draped over the sides 20, 22 of two sleeves 16 and is connected by hooks 56, or other structures, such as cinch straps. The netting 58 provides the stability to the system in place of the bar 24.

[0053] The pallets 14 in each product transfer system 10 shown in FIGS. 1-6 are positioned adjacent and potentially abutting each other. The sleeves 16 supported on the pallets 14 are slightly separated. As shown in FIG. 3 there is a small gap 60 between the back walls 18 of the sleeves 16.

[0054] While FIGS. 1-6 show two separate product transfer systems 10 supported on the forklift 12, it is possible to provide structure connecting the systems to provide additional stability during transport.

[0055] As illustrated in FIGS. 13-15, a latch mechanism 64 in the channel 44 can be used to secure the sleeve 16 to the pallet 14. The mechanism 64 includes an inwardly extending protrusion 66 above an opening 68 in the outer wall 42 of the pallet 14. The protrusion 66 has a generally arcuate shape. As shown in FIG. 14, the protrusion 66 can include a plurality of support ribs 70 extending downward from a lower surface of the protrusion 66. The protrusion 66 cooperates with an opening 72 in the sleeve 16 as generally illustrated in FIG. 15 to secure the sleeve 16 to the pallet 14. The pallet 14 can include a plurality of latch mechanisms 64 around the pallet 14. Additionally, the latch can be formed with a protrusion extending outward from the inner wall of the channel 44.

[0056] An alternative aspect of the invention utilizing a dolly as the base member is illustrated in FIGS. 16-23. Instead of using two small format pallets, a product transfer system 74 shown in FIG. 16 uses two dollies 76 to form the base members supporting sleeves 16. The system 74 is shown with netting 58 connecting the sleeves 16 supported on the two dollies 76, however bars 24 (as discussed above) and other similar structure could be utilized to couple the sleeves 16 to provide stability to the system 74.

[0057] Two product transfer systems 74 using dollies 76 as the base members are shown in FIG. 16 positioned on a fork lift 12. A lower view of the dollies 76 on the fork lift 12 is shown in FIG. 18.

[0058] A dolly 76 for use as a base member for the product transfer system 74 is shown without the sleeve 16 or other components of the product transfer system 74 in FIGS. 17A and 17B. The dolly 76 includes a flat upper platform 78 having a support surface 80 with an outer channel 82 along the perimeter of the upper surface 80. The upper platform 78 can be formed from an injection molded plastic or other similar or suitable materials. A plurality of support ribs 84 extend downward from the upper surface 80 as shown in FIG. 17B. Four wheels 86 on swivel casters extend downward from the upper platform 78.

[0059] The upper platform 78 includes both a front and rear inset 88 having side openings for receiving prongs from attachable items to the dolly 76. The insets 88 are configured to receive removable handles 90 as illustrated in FIGS. 19 and 20, and/or training connectors 92 as illustrated in FIGS. 21 and 22. The handles 90 or training connectors 92 are typically utilized after the product transfer system 74 is conveyed to its location and the system 74 is uncoupled.

[0060] FIG. 23 illustrates how a plurality of the product transfer systems 74 are loaded in the trailer portion 94 of a truck. A typical trailer 94 can support fifty two product transfer systems 74.

[0061] Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.
