Description

  The present invention generally relates to a paper pallet as an article conveying means. In particular, the present invention relates to components of various designs that make up pallets and support surfaces and horizontal runners made from laminated sheets.

  As a means for conveying goods, pallets have traditionally been made from wood, plastic or paper. Conventional paper designs utilize a honeycomb or corrugated paper structure to impart structural rigidity to the paper pallet. Many attempts have been made to improve the strength and design of paper pallets.

  (Patent Document 1) includes a support in the form of a hollow rectangular paper tube configured in a spaced equilibrium relationship, a rectangular insert configured to fit securely within both ends of the tube, and fixed to one side of the tube A pallet is disclosed, wherein both the tube and the insert are formed of layered paper joined together and the axes of the tube and the insert are arranged at right angles to each other Has been.

  (Patent Document 2) discloses a portable pallet and a manufacturing method thereof. The pallets are each folded to form a plurality of alternating upper and lower flats and open sides of continuous channels alternating on the top and bottom, with a plurality of such channels on each side A pair of opposing paperboard sheets in the shape of an intervening vertical wall provided, the sheets arranged adjacent so that the facing channels in one sheet are perpendicular to the facing channels in the other sheet A board mounted in a communication channel space where a paperboard sheet and an opposing open channel intersect, with the end of the board engaging the corresponding flat part, A base plate extending to the bottom and means for fixing the seat and the base plate together in a fixed relationship.

  (Patent Document 3) discloses a pallet for handling materials. This comprises a deck board and a plurality of legs fixed to the lower surface of the deck board at specified intervals. The deck board is composed of laminated corrugated fiber boards, each leg is formed by a square tubular frame made of corrugated fiber plates, and one or more pads made of plastic resin are inserted inside. A durable lightweight construction deck board has a top surface that is roughened to prevent the load from slipping. The legs are constructed to support heavy loads without deformation and crushing and are designed not to absorb moisture.

  (Patent Document 4) discloses a corrugated paperboard pallet. The pallet includes a base member having both sides of a first and second pair, and a plurality of row support members secured to the underside of the base member. The support members have openings at opposite ends that receive flaps from the base member and the support block, respectively, to secure the support member to the base member and provide additional strength to the pallet. This pallet design can be conveniently shipped and stored until ready for use and can be assembled entirely by the user.

  (Patent Document 5) discloses an improved lightweight, recyclable and almost completely paper pallet. This pallet is made of a honeycomb paper base and a honeycomb paper support runner or block. The block is protected by a rigid paper cap and is greatly strengthened. Bases, runners, blocks, and caps can have protective liners such as polyethylene or can be treated in other manners to enhance water and moisture resistance.

US Pat. No. 2,559,930 US Pat. No. 2,928,638 US Pat. No. 4,714,026 US Pat. No. 5,285,731 US Pat. No. 5,329,861

  The main object of the present invention is therefore to provide a pallet made from laminated sheets that can be used as an article conveying means.

  Another object of the present invention is that the paper pallet must be economical, light and structurally strong.

  Yet another object of the present invention is that the design of the paper pallet must be simple and versatile to meet various user needs.

  These and other objects are achieved in that a plurality of horizontal runners are placed and joined under a flat sheet or a plurality of parallel spaced apart elongated elements. The elongate element can be flat or T-shaped. Each horizontal runner is substantially hollow and rectangular and is composed of one or more channel members and a plurality of orthogonal core inserts disposed vertically therein. If an integral U-shaped channel member or C-shaped channel member is not available, it can be replaced with two correspondingly arranged and appropriately joined L-shaped elongated members. In the case of a T-shaped elongated element, the top of the horizontal runner and the orthogonal core insert is cut and the T-shaped elongated element is placed at the position of the cut.

  Twelve embodiments of paper pallets made in accordance with the present invention include a two-way pallet and a four-way pallet. Three horizontal runners are used to build a two-way pallet. To build a four-way pallet, the central portion of the lower half of the horizontal runner is left empty and two spaced short support U-shaped channel members are placed towards the ends.

  As can be seen from FIG. 14a, the second design of the horizontal runner (12b) is substantially rectangular with a plurality of orthogonal core inserts (14) arranged vertically between two horizontally facing flanges. Formed from a C-shaped channel member (15). The C-shaped channel member (15) comprises two horizontally facing flanges and a vertical flange along the length of the horizontal runner (12b). The height of the C-shaped channel member (15) substantially corresponds to the height of the orthogonal core insert (14). When the horizontal runner (12b) is used in conjunction with a plurality of T-shaped elongated elements (11a), a plurality of cuts (19) are formed on the upper flange and orthogonal core insert (14) of each C-shaped channel member (15 ′).
