Knockdown pallet structure, and method of erecting and knocking-down the same
View Patent ↗A new and improved knockdown pallet structure comprises a relatively flexible base panel which is fabricated from a suitable woven plastic material, such as, for example, polypropylene, and a pair of laterally spaced, longitudinally extending pockets are secured upon undersurface portions of the base panel so as to accommodate rigid support members, which may comprise rigid thermoplastic tubes or pipes, for accommodating the fork tines of a forklift truck when a pallet structure, having a palletized load disposed thereon, is to be lifted and transported. A pair of semi-rigid cross-brace members are respectively pivotally secured at first end portions thereof upon the pallet structure so as to be movable between a first operative position, at which the pair of semi-rigid cross-brace members will be disposed in a longitudinally spaced, laterally oriented mode, and a second position at which the pair of semi-rigid cross-brace members will be disposed in a laterally spaced, longitudinally oriented mode so as to be disposed parallel to the laterally spaced, longitudinally extending rigid support members in order to permit the entire pallet structure to be rolled up, folded, or otherwise knocked-down, for compact storage and transportation purposes.
1. A knockdown pallet structure for facilitating the lifting and transportation of a load by means of a fork-lift vehicle, comprising:
a base panel having an upper surface portion and an undersurface portion, and defining a first plane when disposed within an operative state for supporting and transporting a load;
a pair of transversely spaced, longitudinally extending rigid support members, disposed upon said undersurface portion of said base panel, for accommodating the fork tines of a forklift vehicle;
means for securing said pair of transversely spaced, longitudinally extending rigid support members upon said undersurface portions of said base panel;
at least one elongated cross-brace member having a first end portion thereof attached to said upper surface portion of said base panel at a first predetermined location of said upper surface portion of said base panel; and
pocket means fixedly mounted upon said upper surface portion of said base panel at a second predetermined location disposed transversely across from said first predetermined location at which said first end portion of said a least one elongated cross-brace member is attached to said upper surface portion of said base panel; and
means for pivotally attaching said first end portion of said at least one elongated cross-brace member to said upper surface portion of said base panel at said first predetermined location such that said at least one elongated cross-brace member is pivotally movable with respect to said upper surface portion of said base panel within a second plane parallel to said first plane defined by said base panel when said base panel is disposed in its operative state, between a first inoperative, knockdown position, at which said at least one elongated cross-brace member is disposed atop said base panel so as to be oriented parallel to said pair of transversely spaced, longitudinally extending rigid support members so as to be operatively disconnected from said pair of transversely spaced, longitudinally extending rigid support members and thereby permit said knockdown pallet structure to attain a knocked-down compact state, and a second operative, erected position at which said first end portion of said at least one elongated cross-brace member is pivotally attached at said first end portion thereof to said first predetermined location of said upper surface portion of said base panel while a second end portion of said at least on elongated cross-brace member is fixedly disposed within said pocket means fixedly mounted upon said upper surface portion of said base panel at said second predetermined location transversely across from said first predetermined location at which said at first end portion of said at least one elongated cross-brace member is pivotally attached to said upper surface portion of said base panel such that said at least one elongated cross-brace member is disposed transversely with respect to said pair of transversely spaced, longitudinally extending rigid support members so as to operatively interconnect said pair of transversely spaced, longitudinally extending rigid support members together such that said erected pallet structure can support a load.
2. The pallet structure as set forth in claim 1 , wherein:
said base panel comprises a woven fabric.
3. The pallet structure as set forth in claim 2 , wherein:
said woven fabric comprises polypropylene.
4. The pallet structure as set forth in claim 1 , wherein:
said pair of transversely spaced, longitudinally extending rigid support members comprise tubular pipe members.
5. The pallet structure as set forth in claim 4 , wherein:
each one of said pair of transversely spaced, longitudinally extending tubular pipe members has a semi-circular cross-sectional configuration.
6. The pallet structure as set forth in claim 4 , wherein:
each one of said pair of transversely spaced, longitudinally extending tubular pipe members is fabricated from polyvinylchloride (PVC).
7. The pallet structure as set forth in claim 1 , wherein:
said at least one cross-brace member comprises a pair of cross-brace members which are pivotally attached upon said base panel at first end portions thereof so as to be disposed within a longitudinally spaced, transversely extending array when said pair of cross-brace members are disposed at said first operative, erected positions, and are disposed within a transversely spaced, longitudinally extending array when said pair of cross-brace members are disposed at said second inoperative, knocked-down positions.
8. The pallet structure as set forth in claim 7 , wherein:
said pair of cross-brace members are pivotally mounted upon said base panel between said first operative, erected position and said second inoperative, knocked-down position.
9. The pallet structure as set forth in claim 8 , further comprising:
pocket means fixedly mounted upon said base panel for fixedly securing said pair of cross-brace members at said first operative, erected positions.
10. The pallet structure as set forth in claim 1 , wherein said means for securing said pair of transversely spaced, longitudinally extending rigid support members upon said undersurface portions of said base panel comprise: p 1 a pair of transversely spaced, longitudinally extending pocket structures.
11. The pallet structure as set forth in claim 1 , wherein said means for securing each one of said pair of transversely spaced, longitudinally extending rigid support members upon said undersurface portions of said base panel comprise:
a pair of longitudinally spaced straps.
12. The pallet structure as set forth in claim 1 , further comprising:
a third longitudinally extending rigid support member interposed between said pair of transversely spaced, longitudinally extending rigid support members for imparting additional support to said pallet structure.
13. The pallet structure as set forth in claim 1 , further comprising:
a pocket disposed atop said base panel; and
an auxiliary support panel disposed within said pocket so as to provide said pallet structure with additional support.
