Definitions

  • the present invention relates to a device for transporting and supporting a load and a method of assembling the device thereof.
  • Pallets are widely used in the transportation and storage of goods.
  • the goods typically packaged in boxes or bags
  • the goods are stacked on the pallet and bound thereto by straps or wrapping for shipment therewith as an integral unit.
  • Loaded pallets are stored in warehouses either on the floor or in racks in adjacent single or multiple level layers.
  • Conventional pallets are usually made of wood. Wooden pallets offer good materials handling and stacking strength characteristics. The decreasing supply of readily available wood is raising the cost of such pallets, however, and such wooden pallets are heavy and bulky to transport.
  • corrugated pallets made of corrugated paperboard and similar materials as a substitute for wooden pallets have gained limited acceptance for some applications.
  • Such corrugated pallets are lightweight, relatively maintenance free and readily disposable or recyclable. They may be transported and stored in unassembled form for maximum space utilization when unloaded, and assembled on-site for loading. After usage, they can be broken down for disposal or recycling just like cardboard boxes and other corrugated products.
  • Known corrugated paperboard pallets provide lightweight, inexpensive alternatives to conventional wooden pallets for some applications, but their strength and rigidity under static and dynamic loading is insufficient to permit wide spread general usage for all types and distribution of goods. Such pallets often have excessive deflection and lack beam strength, which causes their sagging under loads, thereby making the handling, stacking and racking of the pallets impractical and even dangerous.
  • loads are mounted upon spaced beams of a rack and the weight of the load is concentrated on the pallet at the beam.
  • Many so called improved pallet designs do not offer the strength necessary to withstand buckling, crushing or compression when placed upon a rack under a load.
  • a suitable pallet for use on a rack must provide minimal compression at the beams of the rack and zero to minimal deflection between the beams of the rack.
  • Known paperboard pallets do not meet these compression and beam strength criteria.
  • an acceptable pallet must possess the strength to support their intended loads particularly on a rack or conveyor and must be sufficiently durable to withstand repeated use including being lifted with a lift truck or the like while loaded.
  • the pallet must resist deterioration by the elements of the weather. Therefore, it is apparent that there is a need in the industry for a pallet which satisfies these and other criteria and overcomes the associated disadvantages and shortcomings of known pallet and runner designs.
  • the present invention overcomes these and other deficiencies of the above-mentioned drawbacks by providing a device for transporting and supporting a load and a method of assembling the device.
  • the invention provides a considerable reduction of materials with even greater efficiency and economically during operation.
  • the present invention provides a device for transporting and supplying a load comprising, at least two parallel runners, each runner comprising at least two pairs of substantially vertical oriented reinforcing inserts which spaced apart each other interiorly of the runner; a top wall portion forming a top layer of the runner; a bottom wall portion forming a bottom layer of the runner such that the top wall portion and the bottom wall portion are parallel each other; wherein the reinforcing inserts are positioned between the top wall portion and the bottom wall portion and at least one opening slot is provided on the top wall portion for each reinforcing insert; and at least one panel positioned substantially orthogonal on the runners, the panel having a planar top surface and at least one insertion extended from the planar top surface which disposed into the opening slots of the top wall portion of the runners.
  • the two runners are placed adjacent to each other and the runner is a longitudinal extent and substantially rectangular cross-section.
  • the reinforcing insert is substantially longitudinal extent and substantially rectangular cross-section and the reinforcing insert provides strength and resistance to compression of the runner during use.
  • the space apart between runners to another provides an opening for allowing a fork of a forklift to be inserted into the opening in a direction substantially perpendicular to the runners for lifting the device.
  • an interconnection is formed between the panels positioned substantially orthogonal on the runners.
  • the insertion of the panels having a size and a depth equivalent to the size and depth of the opening slot of top wall portion of the runners.
  • a plurality of insertions of the panels is relatively according to a plurality of opening slots of top wall portion of the runners.
  • a means of fixable attaching is provided for the formation of runners and panels to form a rigid structure.
  • Each components of the device is made from corrugated paper, hardboard, paperboard, cardboard, laminated paper and entirely recyclable and each component of the device is treated for water resistance and water repellency.
  • the device for transporting and supplying a load of the present invention is a paper pallet. Strength of the pallet is able to support a load at least 500 kg to 3000 kg concentrated between the spaced panels of the pallet.
  • a method of assembling a device for transporting and supplying a load comprising providing at least two pairs of substantially vertical oriented reinforcing inserts which spaced apart each other in between a top wall portion and a bottom wall portion of the runner; attaching and positioning the reinforcing inserts in a predetermined position of the runner; providing an opening slot to the top wall portion for each reinforcing inserts of the runner; arranging at least two runners in a parallel position to each other; and placing at least one panel positioned substantially orthogonal on the runners, the panel having a planar top surface and at least one insertion extended from the planar top surface which disposed into the opening slots of the top wall portion of the runners.
  • a product obtainable from the method of the preceding claims is a paper pallet.
  • the pallet design provides for the ability of the pallet to absorb and withstand motion shock in all directions. By providing for interlocking members between panels and runners, the pallet will not collapse because of any side motion pressure. Prior art pallets do not have this ability and are thus subject to failure when used to transport loads by truck or rail over long distances. Especially, the transportation expense can be advantageously reduced when the pallets are reciprocally used (in a returnable manner) on the cargo loading operation, which cannot be accomplished by the prior resin, wooden or metal pallet. User different size and strength requirements can be met without the need to vary the overall design. Changes in dimensions, weight and type of material utilized, etc., will not interfere with the basic performance characteristics.

Description

A DEVICE FOR TRANSPORTING AND SUPPORTING A LOAD AND METHOD OF
ASSEMBLING THE SAME
FIELD OF THE INVENTION
The present invention relates to a device for transporting and supporting a load and a method of assembling the device thereof.
BACKGROUND OF THE INVENTION
Pallets are widely used in the transportation and storage of goods. The goods (typically packaged in boxes or bags) are stacked on the pallet and bound thereto by straps or wrapping for shipment therewith as an integral unit. Loaded pallets are stored in warehouses either on the floor or in racks in adjacent single or multiple level layers.
Conventional pallets are usually made of wood. Wooden pallets offer good materials handling and stacking strength characteristics. The decreasing supply of readily available wood is raising the cost of such pallets, however, and such wooden pallets are heavy and bulky to transport.
The use of pallets made of corrugated paperboard and similar materials as a substitute for wooden pallets has gained limited acceptance for some applications. Such corrugated pallets are lightweight, relatively maintenance free and readily disposable or recyclable. They may be transported and stored in unassembled form for maximum space utilization when unloaded, and assembled on-site for loading. After usage, they can be broken down for disposal or recycling just like cardboard boxes and other corrugated products.
Known corrugated paperboard pallets provide lightweight, inexpensive alternatives to conventional wooden pallets for some applications, but their strength and rigidity under static and dynamic loading is insufficient to permit wide spread general usage for all types and distribution of goods. Such pallets often have excessive deflection and lack beam strength, which causes their sagging under loads, thereby making the handling, stacking and racking of the pallets impractical and even dangerous. Commonly, loads are mounted upon spaced beams of a rack and the weight of the load is concentrated on the pallet at the beam. Many so called improved pallet designs do not offer the strength necessary to withstand buckling, crushing or compression when placed upon a rack under a load. A suitable pallet for use on a rack must provide minimal compression at the beams of the rack and zero to minimal deflection between the beams of the rack. Known paperboard pallets do not meet these compression and beam strength criteria.
Additionally, known paperboard pallet designs typically become compressed, crushed, milled off or damaged when used under a load being transported on a roller conveyor. Moreover, corrugated paperboard, for instance, may lose up to 50 percent of its stacking strength during conditions of high humidity and moisture when the paperboard absorbs atmospheric moisture and the like.
Thus, there is an increasing need for pallets which are economically and ecologically feasible. However, an acceptable pallet must possess the strength to support their intended loads particularly on a rack or conveyor and must be sufficiently durable to withstand repeated use including being lifted with a lift truck or the like while loaded.
Further, desirably the pallet must resist deterioration by the elements of the weather. Therefore, it is apparent that there is a need in the industry for a pallet which satisfies these and other criteria and overcomes the associated disadvantages and shortcomings of known pallet and runner designs.
The present invention overcomes these and other deficiencies of the above-mentioned drawbacks by providing a device for transporting and supporting a load and a method of assembling the device. The invention provides a considerable reduction of materials with even greater efficiency and economically during operation.
SUMMARY OF THE INVENTION The present invention provides a device for transporting and supplying a load comprising, at least two parallel runners, each runner comprising at least two pairs of substantially vertical oriented reinforcing inserts which spaced apart each other interiorly of the runner; a top wall portion forming a top layer of the runner; a bottom wall portion forming a bottom layer of the runner such that the top wall portion and the bottom wall portion are parallel each other; wherein the reinforcing inserts are positioned between the top wall portion and the bottom wall portion and at least one opening slot is provided on the top wall portion for each reinforcing insert; and at least one panel positioned substantially orthogonal on the runners, the panel having a planar top surface and at least one insertion extended from the planar top surface which disposed into the opening slots of the top wall portion of the runners.
In one embodiment of the present invention, the two runners are placed adjacent to each other and the runner is a longitudinal extent and substantially rectangular cross-section. In yet another embodiment of the present invention, the reinforcing insert is substantially longitudinal extent and substantially rectangular cross-section and the reinforcing insert provides strength and resistance to compression of the runner during use.
In another embodiment of the present invention, the space apart between runners to another provides an opening for allowing a fork of a forklift to be inserted into the opening in a direction substantially perpendicular to the runners for lifting the device.
In one embodiment of the present invention, an interconnection is formed between the panels positioned substantially orthogonal on the runners. In another embodiment of the present invention, the insertion of the panels having a size and a depth equivalent to the size and depth of the opening slot of top wall portion of the runners.
In yet another embodiment of the present invention, a plurality of insertions of the panels is relatively according to a plurality of opening slots of top wall portion of the runners. A means of fixable attaching is provided for the formation of runners and panels to form a rigid structure.
Each components of the device is made from corrugated paper, hardboard, paperboard, cardboard, laminated paper and entirely recyclable and each component of the device is treated for water resistance and water repellency. The device for transporting and supplying a load of the present invention is a paper pallet. Strength of the pallet is able to support a load at least 500 kg to 3000 kg concentrated between the spaced panels of the pallet.
A method of assembling a device for transporting and supplying a load comprising providing at least two pairs of substantially vertical oriented reinforcing inserts which spaced apart each other in between a top wall portion and a bottom wall portion of the runner; attaching and positioning the reinforcing inserts in a predetermined position of the runner; providing an opening slot to the top wall portion for each reinforcing inserts of the runner; arranging at least two runners in a parallel position to each other; and placing at least one panel positioned substantially orthogonal on the runners, the panel having a planar top surface and at least one insertion extended from the planar top surface which disposed into the opening slots of the top wall portion of the runners.
