creates box beam sections in the upper deck 12 this significantly increases the strength and stiffness of the upper deck 12 fig8 is a front view of the pallet 10 fig9 is a section view of the pallet 10 and reinforcement sheet 30 taken along line 9 9 of fig5 the reinforcement sheet 30 is vibration welded to the ribs 24 which extend perpendicular to one another in the upper deck 12 this creates the box beam sections fig1 is a bottom view of the pallet 10 with the reinforcement sheet 30 secured thereto the feet 14 are received within the openings 32 in the sheet 30 the center foot 14 is completely circumscribed by the center opening 32 while the side feet 14 c are partially circumscribed more than 180 degrees but less than 360 degrees and the corner feet 14 b are circumscribed less than 180 degrees further the openings 34 align with the handle openings 20 the apertures 36 provide drainage to the box beam sections i e the cavities defined among the upper planar member 18 fig1 the cross ribs 24 fig2 and the reinforcement sheet 30 u201c lower planar member u201d the pallet 10 can thus be easily provided in two versions one with the reinforcement sheet 30 or alternatively without the reinforcement sheet 30 to provide either a stronger stiffer pallet 10 or a lighter pallet 10 in accordance with the provisions of the patent statutes and jurisprudence exemplary configurations described above are considered to represent a preferred embodiment of the invention however it should.
