Abstract

A framework being formed a plurality of beams 1 of square hollow body of paperboard treated for water resistance and water repellency engaged at predetermined distance with and adhered to a pair of channel-shaped bended edge members 4 of paperboard material faced to each other, strip-like boards 2 being placed in parallel to each other on both of front and back faces of the beams 1 with a gap provided between adjacent strip-like boards 2 in a direction perpendicular to a longitudinal of the beams 1 and adhered to the beams 1, each of the strip-like boards 2 formed of a pattern paper treated for water resistance and water repellency and covering all the periphery of front and back faces of an inner core member of thick paperboard and each of the strip-like boards being treated by coating agent for water resistance and for water repellency and fork insertion openings 4 provided in the bended edge members having paperboard layers bended and superposed so as to reinforce upper and lower faces of portions where the fork insertion openings are provided.

Claims

1. A cargo loading and unloading pallet characterized by comprising a framework having a pair of channel-shaped elongated bended edge members of paperboard material faced to each other and a plurality of beams of square hollow body of paperboard material treated for water resistance and water repellency, having both ends engaged with said bended edge members in a manner perpendicular to a longitudinal direction of said bended edge members and placed in parallel to each other in a manner spaced at predetermined distance whereby forks of a forklift truck, a stacker or the like can be inserted between them;

and strip-like boards placed in parallel to each other on both or either of front and back faces of said beams with a gap provided between adjacent strip-like boards in a direction perpendicular to a longitudinal of said beams and adhered to said beams;

each of said strip-like boards formed of an inner core member of thick paperboard such as solid board and a pattern paper treated for water resistance and for water repellency and covering all the periphery of front and back faces of said inner core member; and

each of said strip-like boards being treated by coating agent for water resistance and for water repellency; and

said bended edge members having a pair of fork insertion openings provided in a vertical wall face thereof and having paperboard layers bended and superposed so as to reinforce upper and lower faces of portions where said fork insertion openings are provided.

2. A cargo loading and unloading pallet characterized by comprising a framework having a pair of channel-shaped elongated bended edge members of paperboard material faced to each other and a plurality of beams of square hollow body of paperboard material treated for water resistance and for water repellency, having both ends engaged with said bended edge members in a manner perpendicular to a longitudinal direction of said bended edge members and placed in parallel to each other in a manner spaced at predetermined distance whereby forks of a forklift truck, a stacker or the like can be inserted between them;

and strip-like boards placed in parallel to each other on both or either of front and back faces of said beams with a gap provided between adjacent strip-like boards in a direction perpendicular to a longitudinal of said beams and adhered to said beams;

each of said strip-like boards formed of an inner core member of thick paperboard such as solid board and a pattern paper treated for water resistance and water repellency and covering all the periphery of front and back faces of said inner core member; and

each of said strip-like boards being treated by coating agent for water resistance and water repellency, said bended edge members having a pair of fork insertion openings provided in a vertical wall face thereof and having a reinforcement member of paperboard adhered to upper and lower faces of said bended edge members to reinforce upper and lower faces of portions where said fork insertion openings are provided.

3. A cargo loading and unloading pallet characterized by comprising a top board of paper board having channel-like bend portions elongated in a lateral direction and faced to each other in two faced sides of square or a bottom board following said bend portions and beams of square hollow body of paperboard engaged placed in a direction perpendicular to a longitudinal direction of said bend portions and having both ends engaged with and adhered to said bend portions;

said bend portions having a pair of fork insertion openings provided in a vertical wall face thereof and having a reinforcement frame member of paperboard adhered to said bend portions to reinforce said bend portions where said fork insertion openings are provided and beams provided at places of said bend portions where said fork insertion openings are not provided along a longitudinal direction of said bend portions.

4. A cargo loading and unloading pallet characterized by comprising a framework having a pair of channel-shaped elongated bended edge members of paperboard material faced to each other and a plurality of beams of paperboard material treated for water resistance and for water repellency, having both ends engaged with said bended edge members in a manner perpendicular to a longitudinal direction of said bended edge members and placed in parallel to each other in a manner spaced at predetermined distance whereby forks of a forklift truck, a stacker or the like can be inserted between them;

said beam having a framework formed by cutting at predetermined distance an assembly of a plurality of elongated square hollow body placed in parallel to each other at predetermined distance and flat boards of paper board material adhered to upper and lower faces of said square hollow body, said step of cutting being performed in a direction perpendicular to a longitudinal direction of said square hollow body and said thus formed framework having a plurality of square poles disposed between upper and lower strip-like boards, said beam further having an outer board of paperboard with which said framework is covered on four faces of the periphery thereof, and said pallet further comprising a flat board or boards adhered to both or either of front and back faces of said beams so as to form a top board and/or a bottom board.

5. A cargo loading and unloading pallet as set forth in claim 4, and wherein said outer board surrounding said beam framework having fork insertion openings provided therein for a forklift truck or a stacker.
