FIG. 1 illustratesstackable pallets 20 of apallet system 10 according to the present disclosure. Thepallet system 10 holds any of a variety of items on thestackable pallets 20 which can be moved and stacked on top of one another for storage, transport, and use. Thestackable pallets 20 each have atop end 21, abottom end 25, andsides 22 a-d and each have vertical corner pieces or supports 26 connected to one another at intersections of thesides 22 a-d. Eachcorner piece 26 has a top connector ortoe 30 disposed at a top end and has a bottom connector orreceptacle 28 at a bottom end. To stack thepallets 20, thebottom connector 28 engages thetop connector 30. In particular, thereceptacle 28 of eachcorner piece 26 on a top one of thestackable pallets 20 is adapted to receive or fit on thetoe 30 of a corresponding one of thecorner pieces 26 on a bottom one of thestackable pallets 20. - In general, the
pallet 20 can be composed of any suitable materials, such as metal, wood, plastic, or the like, depending on the durability required and the items to be held. As shown, thepallets 20 can have foursides 22 a-d, although other configurations of three or more sides can be used. Additionally, thevertical pieces 26 need not be specifically at the corners of thesides 22 a-d. - The
corner pieces 26 are structural in nature and, therefore, can be constructed in a manner to support a significant amount of weight. In fact, the weight of items on the pallet'ssurface 24 and fromother pallets 20 stacked above transfers to thecorner pieces 26, which can stably support the load. Thecorner pieces 26 in one particular implementation can be hollow square tubing composed of metal and can be 2-inches wide. Thereceptacle 28, then, of thecorner piece 26 can be the open, hollow ends of the tubing used. Of course, thepieces 26 can be cylindrical, solid, or other shape. - The
pallet 20 can be rectangular, square, triangular, round, oval, or any other shape. The current configuration shown is rectangular. In overall size, one configuration of therectangular pallet 20 can be 17-in. high, 36-in. wide along theshort sides 22 a-b, and 44-in. along the long sides 22 c-d. The bottom ends of thecorner pieces 26 can extend about 3-in. below the lower edge of thesides 22 a-d, while the top end andtoe 30 can extend about 2-in. above the upper end of thesides 22 a-d. Of course, other sizes can be used depending on the items to be held with thepallet 20. - As also shown, the
bottom end 25 of thepallets 20 has arack surface 24 for placing and holding items thereon. Therack surface 24 depicted here is latticed metal mesh, but another other suitable surfaces can be used, such as a flat surface, sheet metal, lateral slats, bars, etc. - The
sides 22 a-d of thepallet 20 may also have surfaces orsidewalls 23. For example,FIG. 2A shows a long side 22 c-d of astackable pallet 22. The side 22 c-d has asidewall 23 constructed by cross members orslats 23 a-b on upper and lower edges of ametal mesh 23 c. Any number of other constructions can be used for thesidewall 23. The benefit of using themesh 23 c is that the items held on the pallet'srack surface 24 can be seen through themesh 23 c. Theslats 23 a-b and mesh 23 c connect between adjoiningcorner pieces 26 to form thesidewall 23 on the side 22 c-d of thepallet 20. Theslats 23 a-b can be L-shaped bars that form a bottom edge to support therack surface 24 and that form a side edge to help hold items on therack surface 24. - As shown in
FIG. 2B , ashort side 22 a-b of thestackable pallet 20 shows how therack surface 24 may be supported underneath by one ormore crossbeams 27 that extend between lower slats 23 b. The need, size, and number ofcrossbeams 27 depends on how much support is needed for the items to be held on thepallet 20. Thecrossbeam 27 can be a 2-in. by 3-in. hollow beam composed of metal or the like. - As mentioned above, each
corner piece 26 of the disclosedpallets 20 has atoe 30 disposed on a top end thereof. Although it is not strictly necessary that eachcorner piece 26 has atoe 30, it is preferred that they do for adequate support. As shown inFIG. 3A , thetoe 30 can be a nestingcap having edges 32 that surround an extendedcentral portion 34. As shown inFIG. 3B , theedges 32 attached by welding or the like to the top end of thecorner pieces 26 so that the extendedcentral portion 34 extends beyond the top end. Theextended portion 34 can be square in shape and can be about 1-in. wide for use withcorner pieces 26 that are 2-in. square tubing. - As will be appreciated, various other types of toes can be used. Moreover, instead of having the
toe 30 for the top connector at the top end and having thereceptacle 28 for the bottom connector at the bottom end of thecorner pieces 26, the reverse arrangement could be used as shown inFIG. 2C . As such, reference to top and bottom here and in the claims is merely meant to be illustrative for the purposes of understanding. - As noted previously, the
stackable pallets 20 can be stacked one on top of another for the purposes of storage, transport, and use. A particular arrangement ofstackable pallets 20 for thesystem 10 illustrated inFIG. 4 has astand 40 on which thestackable pallets 20 can stack. Thestand 40 is similar to thestackable pallets 20 having atop end 41, abottom end 45, and sides 42. Vertical corner pieces or supports 46 are connected to one another at intersections of thesides 42 of thestand 40, and eachcorner piece 46 has a top connector ortoe 48 disposed at its top end. - During use, the
stackable pallets 20 can stack one on top of the other on thestand 40. In particular, thereceptacle 28 of eachcorner piece 26 on the bottom one of thestackable pallets 20 receives or fits on thetoe 48 of a corresponding one of thecorner pieces 46 on thestand 40. Then, additionalstackable pallets 20 can stack thereon as described previously. Finally, the entire stack can be moved about on afloor using casters 44, wheels, or the like disposed on thebottom end 45 of thestand 40, preferably at thecorner pieces 46. - Previous embodiments of the
stackable pallets 20 have had sidewalls enclosing all thesides 22 a-d of thepallet 20. This is not strictly necessary because other embodiments ofpallets 20 may have fewer closed sidewalls. InFIG. 5A , for example, thestackable pallet 20 has threesides 22 b-d enclosed withsidewalls 23, but has oneopen side 22 a allowing items to be inserted and removed from therack surface 24 through that openedside 22 a. In another example ofFIG. 5B , astackable pallet 20 has fouropen sides 22 a-d. - In still other embodiments, one or more sidewalls 23 may be removable or may be openable on a
side 22 of thepallet 20. In one example shown inFIG. 5C , asidewall 23 can be affixed byhinges 50, fasteners, or the like to one of thesides 22 a-d of thepallet 20 inFIG. 5A . In another example shown inFIG. 5D , asidewall 23 can haveend tubes 52 that slide onadjacent corner pieces 26 to form aremovable sidewall 23 on aside 22 a-d of thepallet 20 inFIG. 5B . These and other configurations are possible. - As shown in
FIG. 6 , the various types ofstackable pallets 20 can be stacked one on top of the other as before and can be used on astand 40. InFIG. 6 , for example, thesystem 10 has a bottommost pallet 20A with four enclosed sides stacked on thestand 40. The nextstacked pallet 20B has one open side, and thetop pallet 20C has all four open sides. Moreover, the embodiment of thetop pallet 20C depicted inFIG. 6 has tworack surfaces 24 disposed between thecorner pieces 26. These and other configurations ofpallets 20 can be stacked in any desirable order on thestand 40. - Filling and emptying the
stacked pallets 20 inFIGS. 4 and 6 can be performed as expected, depending on whether a givenpallet 20 has open sides or not or has to be filled or emptied when another pallet is not stacked on top of it. When it is desired to move thestacked pallets 20 by lifting it on a truck, shelf, or the like with a forklift or other device, the forks can fit under the bottom end of the lowermost pallet 20 to lift all of thepallets 20 while leaving thestand 40 in place. Thestacked pallets 20 can be tied together with tie rods disposed longitudinally thereabout to hold the stack together if desired. - In addition, the various
stacked pallets 20 can be locked together and can be locked to thestand 40 using any of a number of locking mechanisms or fasteners. As shown inFIG. 7A , for example, onelocking mechanism 60 for thestackable pallets 20 can use a c-clamp 62, clip, or the like that fits in cross-holes in thecorner pieces 26 betweenstacked pallets 40. Fasteners 64, such as butterfly nuts or the like, can then thread onto the free ends of the c-clamp 62 to affix the twocorner pieces 26 together. A similar mechanism can be used on one or more of theother corner pieces 26 between thestacked pallets 20. - As shown in
FIG. 7B , another locking mechanism 70 for thestackable pallets 20 can use a bolt 72 that fits in cross-holes in thecorner piece 26 at thereceptacle 28 and that fits in a cross-hole 31 in thetoe 30 betweenstacked pallets 40. Here inFIG. 7B , thetoe 30 is depicted as an extended bar, but other shapes can be used. A fastener 64, such as butterfly nuts or the like, can then thread onto the free end of the bolt 72 to affix thetoe 30 inside thereceptacle 28. A similar mechanism can be used on one or more of theother corner pieces 26 between thestacked pallets 20. - When one or more of the
corner pieces 26 of stackedpallets 20 are affixed together with the lockingmechanisms 60 and 70 in the manner described, the stack ofpallets 20 can have improved stability. Although not shown, locking mechanisms such as the c-clamp device 60 and bolt device 70 ofFIGS. 7A-7B can be used at the junction of the stand'scorner pieces 46 and thosecorner pieces 26 of thepallet 20 stacked thereon. - The foregoing description of preferred and other embodiments is not intended to limit or restrict the scope or applicability of the inventive concepts conceived of by the Applicants. It will be appreciated with the benefit of the present disclosure that features described above in accordance with any embodiment or aspect of the disclosed subject matter can be utilized, either alone or in combination, with any other described feature, in any other embodiment or aspect of the disclosed subject matter.
- In exchange for disclosing the inventive concepts contained herein, the Applicants desire all patent rights afforded by the appended claims. Therefore, it is intended that the appended claims include all modifications and alterations to the full extent that they come within the scope of the following claims or the equivalents thereof.
