  • This invention relates to a knockdown pallet having a plurality of tubular base members suitable for engagement with the floor of a warehouse.
  • a plurality of load support members extend across and rest upon the base members and are designed to carry or support a plurality of merchandise boxes, barrels, or other containers above the surface of the warehouse floor.
  • prior knockdown pallets have used a large number of independent parts which are easily lost and dictate a large expenditure of time to assemble and disassemble the pallet. Further, priorly known knockdown pallets occupy a relatively large storage volume even in the knockdown posture.
  • Yet another object of the invention is to provide a novel warehousing pallet having upper load supporting cross members supported parallel to the floor by the lower tubular base members, each of which has a different diameter, whereby all the base members may be nested and all of the upper cross members may be contained within the base members.

  • FIG. 20 is a broken away view of one junction of a cross and base member of the knockdown pallet shown in FIG. 18.
  • FIG. 24 is an end elevation taken in cross section of a stored knockdown pallet such as shown in FIGS. 12 or 15.
  • FIG. 25 is an end elevational view taken in cross section of a stored knockdown pallet such as shown in FIG. 18.
  • FIG. 26 is a cross sectional view of an end cap suitable for use with the stored knockdown pallet, as shown in FIG. 24.
  • FIGS. 1-4 there is shown a warehousing or shipping pallet 30 in accord with one form of the invention, having a plurality of tubular load supporting cross members 32 extending normally to the axis of, and resting upon, a plurality of base members which are here illustrated as being hollow, thin-walled, cylindrical tubes 34, 35 and 36.
  • the diameters of the base tubes are not equal, but rather are progressive, such that the inside diameter D-l of tube 34 is greater than the outside diameter D-2 of tube 35, and the inside diameter D-2 of tube 35 in turn is greater than the outside diameter D-3 of tube 36.
  • the loadsupporting cross members 32 must extend with an upper surface approximately parallel with the floor to prevent shifting or rolling of the commodities carried by the pallet.
  • a plurality of openings or recesses of decreasing depth 39, 40 and 41 are fashioned into the base members 34, 35, and 36, respectively.
  • the openings 39, 40 and 41 in the embodiment illustrated in FIGS. 1-3 are all generally cylindrical voids to thus accommodate in intimate reception cross members 32 which have a cylindrical outer surface.
  • cross members 32 may be provided with three normally extending openings (note FIGS. 3, 4 and 5), through which dowel pins or tie-rods 44 may extend.
  • the dowel pins 44 may be slidingly received within and along a line parallel to the axis of respective base tubes 34, 35 and 36. Dowel pins 44 thus extend perpendicularly through the plurality of load support cross members 32.
  • the dowel pin receiving openings in the cross members must be located so that, in each case, the dowel pins 44 slide along the upper interior surface of the base members 34, 35 and 36.
  • the base members 34, 35 and 36 and cross members 32 of the shipping pallet may be made up from tubular parts, preferably of thin-walled material, being light in weight yet possessing great strength and load-bearing characteristics.
  • a variety of compositions may be used for this purpose such as light metals and metal alloys, plastics and reinforced plastics such as molded fiberglass, rolls of treated wood or paper and reinforced treated paper, or the like.
  • composition which has been found particularly suitable is a roll of paper or a roll of paper reinforced with a screen of a metallic or fiberglass material, impregnated with a liquid monomer and thereafter polymerized to produce a very hard and strong paper-plastic composite.
  • the step of polymerization may be accomplished as by subjecting the monomer impregnated roll or tube to intense irradiation or heat, as disclosed in my copending application, Ser. No. 678,584, filed Oct. 27, 1967.
  • a rigid sheet of plastic impregnated paper or the like may be laid on the load-support members and attached thereto by suitable retaining means.
  • the pallet 30, as shown in FIG. 1, is so dimensioned as to enable a conventional forklift truck (not shown) to engage its lifting tongs from either of two directions along the avenues indicated by arrows E, and B In some instances, however, it is desirable to provide four-way entry to the pallet.
  • a pair of recesses 46 may be fashioned through the base tubes normally to the base tube axes.
  • the base tubes are still provided with adequate floor engaging legs 48 which are suitable to maintain the strength requirements of the base tubes.
  • a pallet structure having two legs may be adequate.
  • a modified pallet is disclosed having a first base tube 50 which is diametrically larger than a second base tube 52 which will horizontally support a plurality of cross members 32 and nest in a knockdown condition in the manner previously described.
  • FIGS. 7-11 a pallet 55, designed for heavy duty, is disclosed.
  • a plurality of load supporting tubes 32 are positioned for intimate contact and support upon a plurality of base tubes 34, 35 and 36 which have decreasing diametrical dimensions.
  • the load support members 32 engage holes or grooves 39, 40 and 41 in the base tubes and are held in position by a plurality of dowel pins or tie-rods 44, as best seen in FIGS. 8, 9, l0 and 11.
  • the heavy duty pallet 55 therefore, is identical in many respects with the pallet 30 disclosed in FIGS. l-6.
  • the heavy duty pallet additionally may be provided with a plurality of stabilizing bars 57 which extend parallel to the load supporting cross tubes and normally through recesses formed in the bottom portions of the base tubes 34, 35 and 36.
  • the stabilizing bars extend approximately an equal distance into receiving holes or slots 59 in each of the base tubes.
  • the stabilizing bars 57 are fixedly attached in intimate engagement with the base tubes by tierods or dowel pins 61 which extend longitudinally with the base members and normally through the stabilizing bars.
  • a pair of recesses 46 may be laterally provided through the base tubes, as best seen in FIG. 11.
  • only four of the lower stabilizing bars 57 have been deleted, thus leaving at least one stabilizing member 57 on each side of the recesses 46 for strength and rigidity.
  • the bars 57 may be fastened to the base members by a plurality of short ties 58 to provide and maintain the forklift entry free from obstructions.
  • FIGS. 12 and 13 A further embodiment of the invention is disclosed in FIGS. 12 and 13 wherein a warehousing pallet 62 is shown having a plurality of cross bars 32 extending normally to and resting upon a plurality of cylindrical segmented base members 63.
  • the base members 63 are peripheral or circumferential seg ments of a longitudinally sectioned tubular member. Each of the base members 63, as shown in FIG. 13, has substantially similar dimensions and in cross section peripherally comprises about one-third of a generally circular shell.
  • the edges 65 of the base members 63 are positioned for engagement with the floor of a warehouse or bed of a truck, and the upper arcuate portions or crowns 67, therefore, are above the floor surface.
  • the crowns are provided with a plurality of normally extending holes or recesses 69 therethrough. The recesses are fashioned for the cooperative reception of the normally extending load support members 32.
  • a dowel pin 44 may be positioned within and continguous to the inner crown portion 67 of the base means 63 and through he normally extending cross members 32 for the fixed attachment of the cross members 32 to the base members 63.
  • FIGS. 12 and 13 has been shown comprising three base members 63, that in some instances where light loads are anticipated, a pair of generally semicylindrical base members 71, as illustrated in FIG. 14, may be used.
  • FIGS. 15 and 16 Another embodiment of the invention, as illustrated in FIGS. 15 and 16, comprises a warehousing pallet 73 having a plurality of tubular load-supporting cross members 32 extending normally to and cooperatively engaging a plurality of base members 75.
  • the base members 75 are composed of longitudinally extending sections of a generally circular tubular member. Each base member in cross section comprises about one-third of the peripheral or circumferential portion of a circular tubular member.
  • the crown portions 77 of the base members 75 are positioned for engagement with the bed of a truck or warehousing floor.
  • the cross members 32 are provided with a plurality of slots 81 formed to intimately receive the upturned edges 79 in each base member.
  • the load supporting cross members 32 may be secured to the base members 75 by fashioning a plurality of holes through the edges 79 of the base members and inserting dowel pins 44 within the cross members and through the holes in the base members. Another means of securing the base members and load supporting cross members together is disclosed in FIG. 17, wherein the inside base cordial distance C is approximately equal to the outside slot distance S. Therefore, the base member 75 must be compressed to engage the slots 81 in the cross members 32, and thus the members are held in engagement by the resultant compressive force.
  • a still further embodiment of the pallet of this invention may comprise a shipping or warehousing pallet 83, as illustrated in FIGS. 18-20, wherein tubular cross members 84 having a rectangular or square cross section extend normally to and cooperatively rest upon base tubes 86, 87 and 88 which also have rectangular or square cross sections.
  • the cross-sectional dimensions of the base tubes are not equal but rather are progressive such that the width of the one side L1 of base tube 86 is greater than the width L2 of tube 87, which in turn is greater than the width L3 of tube 88.
  • the upper portions of the varying diameter tubes rest on a plane such as the floor of the warehouse or the bed of a truck, the upper portions thereof will necessarily ascend or descend in step fashion as illustrated in FIG. 19.
  • the square base tubes 86-88 may be provided with a plurality of normally extending slots 90 for the cooperative reception of the side portions 92 of the normally extending load support members 84.
  • the load support members 84 are further fashioned with U-shaped cutouts 94.
  • the slots 90 receive the side portions 92 of cross members 84 and the U-shaped cutouts 94 slide over walls 98. Therefore, the bottom bearing edges 96 and side portions 92 of the cross members will cooperate with the side walls 98 and slots 90 to restrain movement of the cross members 84 along either the axis of the dross member or the axis of the associated base members 86-88.

  • a pair of recesses 46 may be laterally provided through the base tubes, as best seen in FIG. 21.
  • the warehousing pallet 30 and 55 when disassembled, permit the compact storage of all of the pallet elements within the largest of the base members.
  • the base tubes 34, 35 and 36 are cross-sectionally dimensioned to nest within each other, thus providing a hollow void for the reception of the cross members 32 and also the tie-rods or dowel pins 44.
  • a pair of end caps may then be positioned over each end of the base member, as best seen in FIG. 22. The end caps may be held in position by an interference fit, screw threads, pin connections, or the like.
  • the warehousing pallets 62 and 73 may be com pactly stored as illustrated in FIG. 24.
  • the peripherally segmented base members 63 or 75 circumferentially cooperate to form a single, longitudinally extending cylindrical tube for the reception of a plurality of the cross members 32, and (when used) dowel pins or tie-rods 44.
  • a pair of end caps 101 each have'a circular recess 102 which may engage the inner and outer surfaces of the base members 63 or 75 and hold them in the configuration of a cylindrical tube.
  • the end caps 101 which are positioned over each end of the single tubular member to maintain the structure during shipping and storage, may be secured to the tube in any suitable manner, such as by an interference fit as here illustrated.
  • the warehousing pallet 83 also breaks down into a compact structure for transportation and storage, as illustrated in FIG. 25.
  • the base tubes 86, 87 and 88 are dimensioned to telescopically cooperate, as previously discussed, and receive in their interior the normally extending cross members 84 and the dowel pins or tie-rods which make up the pallet.
  • a pair of suitable end caps may be placed on each end of the base tube to maintain the integrity of the compact knockdown pallet unit during shipping and storage.
  • the present invention provides a novel knockdown pallet which may be easily transported and stored for reuse a number of times.
  • the pallet may weigh as little as a fourth of that of a conventional wooden pallet and may occupy as little as one-tenth the volume when in the knockdown condition.
  • the pallet of the present invention may provide a considerable cost savings in pallet transportation and storage management even over previously known knockdown pallets.
  • the pallet being light in weight and compact, is therefore easily hand carried. It is composed of a plurality of members, many of which are interchangeable, which may be manually assembled and disassembled. Therefore, defective or worn elements may be replaced as needed and the entire pallet need not be discarded merely because one part is damaged.
  • the knockdown pallet comprises a minimum of separate elements therefore maximizing the ease and rapidity with which the pallet may be assembled and disassembled.
  • the knockdown pallet of the invention may be self-contained within a single tubular member having end caps when in the knockdown posture. Therefore the integrity of the separate pallet elements may be maintained during transportation and storage.
