This invention relates to the field of shipping packages and objects, to an improved shipping system for shipping such packages and objects, and to the methods of use of such systems and also pallets.
In the past, pallets have been used for shipping packages and objects, which have been typically constructed of rough wood. Some have been used that have been presswood, plastic, and aluminum. Wood pallets typically allow for forklift movement of the pallets and their loads. Some allow forklift access from two opposed sides, and are said to provide 2-way forklift access. Others provide 4-way forklift access. Some have been made “nestable,” or able to be nested one on top another for ease of stacking Some have integrated sidewalls to become containers, and have been collapsible and stackable. Some are made specifically for 55 gallon drums, others specifically for sheetfed press runs, rolls of film, paper and the like, and still others for television display panels. Some are less sturdy, for limited use, and others more sturdy, for extended use. Numerous remain wood pallets of conventional construction.
With wood pallets, and even the ones more “high tech,” some shipments suffer greatly with shipment damage. This is especially true with many goods packaged in paperboard and small flute corrugated boxes and cartons, often called folding and folded cartons. The goods in such cartons include many consumer products, from medicines and pharmaceuticals, to foods such as breakfast cereals, pasta and chocolates, through toys, consumer electronics and automotive parts. In these boxes, many products have been damaged and their boxes crushed from forklift damage and their own weight when overstacked. As a result, needs have existed over years and decades for shipping systems that provide improved transportation for more fragile loads such as paperboard loads. The needs include ease of loading and unloading, as well as greater heights of loads without self imposed crushing, and the like.
The improved shipping system of this invention was specifically developed to minimize or potentially eliminate crushing, bowing and other damage issues. Increasing the volume of the trailer occupied without fear of having damaged or crushed products is an added benefit that can result in significant freight cost reductions.
In a first embodiment, an improved shipping system includes a base deck section. The system further includes an upper-tier deck section, that moves between a position atop the base deck section through a variety of positions, including positions that put the upper section out of the way of loading and unloading any load on the base deck section. Loaded pallets may be atop both the base deck section and the upper-tier deck section, for shipments, with the upper-tier deck section in the raised configuration. When emptied, the system may be returned with its upper-tier deck section moved down to a position atop the base deck section, and the system stacked upon a similar improved system. Shipping efficiency is increased as much as twenty percent and perhaps more. All components are steel, and may also be plastic, wood and the like.
To provide the movement of the upper-tier deck section, and support it in the position shown, several legs are provided on each end, extending between the base deck section and the upper-tier deck section. The legs are detachable from the upper-tier deck section and/or the base deck section, and may hook into catches. The legs may lie against the base deck sections. The legs may be hinged at their ends.
As described, the upper-tier deck sections provide space between the base deck sections and the upper-tier deck sections for a loaded pallet stacked on and supported by the base deck sections. The upper-tier deck sections also provide for loaded pallets supported by and stacked on the upper-tier deck sections. Shipping costs may be reduced as trucks may be better filled with the systems filled with pallets. The shipping system disclosed may be rented and used multiple times, further improving economy.
In another embodiment, an improved shipping system includes a base deck section similar to the first embodiment. The system further includes an upper-tier deck section, similar to the first embodiment. The upper-tier deck section moves again between a position atop the base deck section through a variety of positions, with less concern for positions that put the upper section out of the way of loading and unloading loads on the base deck section. Again, loaded pallets may be atop both the base deck section and the upper-tier deck section, for shipments, with the upper-tier deck section in the raised configuration. When emptied, the system may again be returned with its upper-tier deck section moved down to a position atop the base deck section, with less concern for stacking Shipping efficiency is increased as much as twenty percent and perhaps more. All components are steel, and may also be plastic, wood and the like.
With the second embodiment, to provide the movement of the upper-tier deck section, and support it in position, several legs are also provided on each end, extending between the base deck section and the upper-tier deck section. On one side, the legs are detachable from the upper-tier deck section. The legs may lie against the base deck sections. The legs may be hinged at their ends.
In a third embodiment, an improved shipping system still includes a base deck section. The system further continues to include an upper-tier deck section, as well. In the third embodiment, the upper-tier deck section is consistently in a position atop the base deck section, and movable through a variety of heights relative to the base deck section. Loaded pallets may be atop both the base deck section and the upper-tier deck section, for shipments, with the upper-tier deck section in the raised configuration and at a height suitable for the height of the loaded pallet put on the base deck section. When emptied, the system may be returned with its upper-tier deck section moved down to a position nearest the base deck section. Stacking is possible, although the first and second embodiments stack more closely together when stacked. Shipping efficiency is continued to be increased as much as twenty percent and perhaps more. All components are steel, and may also be plastic, wood and the like.
To provide the movement of the upper-tier deck section, and support it in position, several legs are still provided on each end, extending between the base deck section and the upper-tier deck section. The legs are extendible and retractable between a variety of positions of the upper-tier deck section relative to the base deck section, and may be pinned to chosen lengths of extension and retraction. The legs stand perpendicular to the base deck sections. The legs are fixed to the based deck sections and the upper-tier deck sections.
The drawings that accompany this description include several figures, each described as follows:
