Definitions

  • This invention relates to portable platforms adapted for use in lift truck operations and generally referred to as skids or pallets.
  • a second disadvantage in present day platforms is the problem of return of empties. Either the platforms are one use” platforms so that their entire value must be absorbed as a shipping or other overhead cost, or else attention and consideration must be given to their return shipment. Since the cost of wooden platforms runs as high as six dollars apiece, and of steel platforms at least double that figure, single use involves an item of considerable consequence, while unloaded return shipment is a nuisance and an added cost.

  • the next panel 88 extends inwardly beneath panel 2 to the longitudinal median, and then is folded upwardly to form an upright 82, back across the top to form an underface 84, down on the outer side to form another upright 85 and then the end panel is formed into a double truss element 88, a fiat upper central portion 81 thereof being stapled, as by staples 88, through and through to the fiberboard sections 2 and 84.
  • An extension on the other side of the central panel 2 of the device of Fig. 14 provides an identical supporting member for the other side of the platform.
  • lift truck fork entry is provided above the panels 80 and in the passageways formed by the trusses 86.
  • double-faced corrugated fiberboard of the type illustrated in Fig, 15. Such fiberboard may of course be used in making any of the other elements heretofore described.
  • Fig. 14 will provide a two-way or a four-way pallet.
  • FIG. 17 Another example of a reinforcing insert is illustrated in Fig. 17 wherein fiberboard sheets 82 are inserted in face-to-face relation but run horizontally instead of vertically of the platform.
  • Fig. 18 shows another form of pallet made from a single piece of fiberboard similar to the device of Fig. 14.
  • the panels 8 and 88 continue into uprights 82 and underfaces 84 and then into trusses 88 instead of into the elements 84 and 88 of the device of Fig. 14.
  • the form of device of Fig. 18 has limited use because the spans of underfaces 84 cannot be made very extensive without sacrifice in strength and it is necessary to maintain uprights 82, 82 in face-to-face relation in' order to prevent lateral sway.
  • Fig. 18 may be made either as a two-way or a four-way platform in accordance with principles hereinbefore explained.
  • gummed paper tapes or other fastening means may be placed at points other than those shown in the drawings in order to maintain the components in assembled condition.
  • the sleeves 4, 6 and 8 should be so fastened as to prevent their separating downwardly from panel 2, This can he done by interposing adhesive at suitable points between underfaces 8, l1 and i8 and panel 2 or by folding gummed tape over their edges.
