The present invention relates to a modular, reusable, containment device for protecting cargo during shipment. The device is suitable for shipping large, fragile, or high-value items such as telecommunications cabinets, appliances, and furniture.
Telecommunications cabinets handle voice and data communications. The cabinets can range in size from approximately a 4′×4′×4′ cube to a commonly-sized 4′×4′×8′ tall cabinet. Housed within are all the routers, switchgear, and other electronics necessary to connect office buildings with the outside world. The electronic components housed within telecommunications cabinets are very expensive, and require a great degree of skill to assemble and correctly wire into place.
Assembling telecommunications cabinets in the field would be difficult, time-consuming, and lacking in quality control. By assembling the units at a single location (e.g., a manufacturing facility), far greater control can be maintained over the quality of assembly.
There is, however, a significant drawback to assembling the cabinets at a central location and then shipping them to another destination for use: the assembled telecommunications cabinets are highly susceptible damage in transit. Telecommunications cabinets are designed and engineered to be stationary units, not as rugged mobile devices. This requires that a great deal of care be taken when shipping the complete telecommunications boxes.
The traditional method for shipping telecommunications cabinets is to (1) place them on a typical wooden skid pallet, (2) attach cardboard, honeycomb, plastic wrap, or other typical shipping materials to the outside of the cabinet, and (3) send the packaged telecommunications box into the stream of commercial logistics until it reaches its final destination. The telecommunications cabinets are generally bolted or strapped to the pallet.
The palletized telecommunications cabinet may travel by truck, train, boat, or plane. Often, it travels by a variety of methods, and may be switched numerous times from one vehicle to another her as it travels from its point of origin to its final destination. In the process, the palletized telecommunications cabinet can be handled many times, and at each point it is susceptible to damage.
Material-handling equipment, such as forklifts, can cause damage to telecommunications boxes. For example, if a forklift operator inadvertently misaligns the forks, he could accidently damage the telecommunications cabinet on the pallet being moved, or the telecommunications cabinet on an adjacent pallet. In addition, the risk of tip-over is prevalent with top-heavy, palletized telecommunications cabinets, particularly when being moved up and down ramps. Finally, vibration and the effects of lateral impacts on the palletized telecommunications cabinets in transit can damage the internal electronics. A related concern is that the materials typically used for shipping telecommunications cabinets are simply discarded as trash once the unit reaches its destination, rather than being recycled.
For at least these reasons, a more secure method of shipping and protecting large, high value, fragile items such as telecommunications cabinets, appliances, grandfather clocks, and furniture is needed. All these items can be securely and safely shipped using the containment device of the present invention.
The present invention provides a novel robust, reusable, modular shipping container for protecting large, fragile, odd-shaped, or high-value cargo (e.g., telecommunications cabinets, appliances and furniture) from damage during shipment. The shipping container minimizes the possibility of shipping damage due to improper handling, tip-overs, lateral collisions, or vibration.

It will be appreciated that Applicant envisions that all logical combinations of the above embodiments (together with additional aspects described below) are further embodiments and aspects of the present invention.
The following drawings and description thereof are meant to exemplify one or more specific embodiments of the invention, and are not intended to limit the scope of the invention in any way.
The modular, reusable, shipping container of the present invention is shown in the figures as comprising: a pallet base 100, a lower frame section 300, an upper frame section 400, and a top cover 500.
The pallet base is constructed of one or more structural materials such as steel, aluminum, wood, plastic or a composite. For many applications, steel provides a good combination of strength, weight, and low cost. The pallet base includes a floor allowing for the use of hand trucks, or appliance-type dollies, to load and unload the cargo while protecting the bottom of the cargo. The floor can include recessed cavities into which foam, or other vibration and shock dampening materials, can be placed. These materials insulate the cargo from the pallet base and absorb any vibrations or shock induced into the shipping container.
The cargo typically rests on vibration and shock-dampening material. The material supports the cargo above the floor and leaves a small space, approximately ½″ to 1″, between the bottom of the cargo and the floor. This gap provides room for the cargo to float on the vibration and shock dampening material. An additional benefit of the gap is that it allows a standard appliance dolly to be slipped into it to facilitate removal of the cargo from the shipping container once the cargo has reached its final destination.
The shipping container of the present invention can further comprise a ramp, e.g., a folding ramp that can be moved between a substantially horizontal down position (for unloading cargo with an appliance dolly or hand truck), and a substantially vertical folded (i.e., stowed) position for transit. The folding ramp can be attached to the pallet base using hinges, and constructed of a suitable material (e.g., steel, aluminum, composite material, wood, or plastic) to provide a desirable combination of strength, weight, and cost for a particular application. Reinforced steel provides sufficient strength, acceptable weight, and low cost for many applications.
When the folding ramp is in the vertical stowed position, it can be secured with safety retainer mechanisms, such as safety cables or safety chains. An additional benefit of this folding ramp is that when in the stowed position, it provides additional protection against damage from forklifts or other material-handling devices by acting as a protective wall on the front side of the shipping container. Other embodiments of the present invention include a ramp which slides in and out of the pallet base, and a ramp which can be completely detached from the pallet base. When the ramp is in the open position, the ramp allows a user of the shipping container to load material onto the shipping container base with a commonly used hand truck, or appliance style dolly. When the ramp is in the stowed, or folded position, it provides additional protection to the cargo contained within the shipping container.
A lower frame section, comprising left and right sides, and optionally a back side, connects to the pallet base and extends generally upward. These sides provide skeletal-like protection for the lower portion of the shipping container, a means for supporting the upper frame sides, and a means for supporting, and hearing the weight of stacked pallets when the shipping container is used in the half-height position. Incorporated into the tops of the lower frame sides are mating connectors, which allow the upper frame sides to be attached to the lower frame sides. The frame sections are preferably made from a plurality of rectangular steel tubes dispersed in a parallel array.
The upper frame sides can be attached to the lower frame sides by engaging female mating connector of the upper frame sides with male connectors of the lower frame sides (or vice-versa), The upper frame sides can be identical, and include strike plates to further protect the cargo from accidental damage. The strike plates provide additional retention of the ramp to prevent it from unfolding and from forklifts inadvertently poking into the cargo, The strike plates can be at the same approximate height that a second level of pallets in a standard two-pallet stack for shipping would be. The upper portions of the upper frame sides can comprise mating connectors that allow the top frame side to be attached thereto with compatible mating connectors (e.g., male/female connectors).
A protective blanket can optionally be placed between the cargo and the inner surfaces of shipping container for additional protection. The protective blanket can comprise a plurality of padded features. Space filling material, such as foam pads, packing air bags, or other typical dunnage materials and items can also be inserted between the protective blanket wrapped cargo and the inner surfaces of the shipping container. For example, air bags can be placed between the cargo and the inner surfaces of the container at various locations to further eliminate any gaps between the container and the cargo. Packing air bags are available in an almost unlimited variety of sizes, shapes, and strengths from a variety of sources such as alibaba.com, Inflatable Packaging, Inc., and others.
A strap mechanism can be used to tighten the unit together. For example, a plurality of ratcheting, nylon straps can be used to bind the unit. The ratchet portion of each of the ratcheting straps can be fixed to the pallet base, and the hook end of the ratcheting strap attached to the top frame side. Once the plurality of straps has been fully tightened, the outer portion of the shipping container frame can be wrapped with a layer of stretch wrap, or with products such as “shrinkwrap”. The stretch wrap provides protection against external moisture, provides a surface upon which shipping labels, and tags, can be affixed to the shipping container, and a visual reference to aid in the detection of cargo damage inflicted during the shipping process.
In certain applications, the upper frame sides can be removed and the shipping container used as in half-height configuration. The upper frame sides can be stored within the lower frame sides, and the top frame side attached to the upper portions of the lower frame sides. In this configuration, the top frame side becomes the top of a half-height shipping container.
An additional benefit of the modular design of the shipping container is that it can protect a telecommunications cabinet during the assembly process. The shipping container, containing the unpopulated telecommunications cabinet, is simply moved to the first stage of the populating process. If multiple stages of assembly are required, the cabinet can be moved on the shipping container throughout the assembly process. Once assembly is complete, a protective blanket can be placed over the cabinet and the ramp secured in the stowed position with safety retainer devices. The upper frame sides can be attached; and ratcheting straps tightened. After the shipping container is wrapped with a layer of stretch wrap film, the unit is ready for shipment.
