The present invention relates to containers for storing and transporting personal watercraft. More particularly, the present invention relates to a transport shipping container that meets manufacturer and watercraft retailer needs for shipping containers readily usable in storing and shipping personal watercraft to remote retailers while facilitating the crating and the unloading of personal watercraft at the manufacturers and at the retailers.
Personal watercraft are increasingly popular for recreational activities. Over the years since introduction, the various models of personal watercraft have changed in size and performance. A manufactured watercraft is packaged in a palletized container for warehouse storage and for shipping by truck from a manufacturer to retailer. Initially, such watercraft were placed in containers that allowed two to be placed side-by-side in a section of a truck and two additional containers stacked on top.
The watercraft however have changed from initial small-beam powered craft to single and multiple seating powerful watercraft having larger beam widths and longer aft-to-stern lengths. The increased beam provides stability for the larger multi-passenger personal watercraft.
The increased beam, or maximum width, of newer models of personal watercraft however poses transport problems. Because domestic (U.S.) truck trailers typically provide about 96-98 inches usable transverse space (nominal 102 inch wide trailers), pallet containers have a maximum of 48 inches width in order to maintain usage at two containers positioned side-by-side in a trailer. A single pallet container leaves significant space that typically is filled with buffer material to restrict movement of the container during transport. However, transport of watercraft in single pallet container loading (rather than side-by-side container transport) increases shipping costs. Export containers are more restrictive with a maximum width of 45 inches for side-by-side positioning in a 90-92 inch usable storage width (nominal 98 inches).
The industry resolved this transport problem by mounting personal watercraft on angled supports of about 40-48 degrees. This positioned a horizontal axis of the personal watercraft at an angle to the pallet that sits parallel to the floor of the trailer. The angled positioning accommodated the larger beam watercraft.
The use of angled support containers however lead to uncrating problems at retailers. The personal watercraft is heavy, long and wide, and can be 1400 pounds or more, with 10-12 foot lengths and 48 inch beams. Retailers generally lack lifting equipment to engage the watercraft angled on the pallet, and then, support and lift the watercraft to a horizontal orientation, and remove the watercraft from the pallet for placing on a wheeled dolly to move to a display or to a body of water.
There is a need in the industry for shipping containers that are readily usable in trucking to remote retailers of personal watercraft mounted at an angled orientation relative to a pallet of the shipping container while facilitating the handling of the personal watercraft at a horizontal orientation for creating for storage and shipping and uncrating of the watercraft for display and sale. It is to such that the present invention is directed.
The present invention meets the need in the industry for a shipping container for personal watercraft readily trucked to remote retailers, which mounts the personal watercraft at an angled orientation relative to a pallet of the shipping container while facilitating the handling of the personal watercraft at a horizontal orientation for crating and uncrating of the personal watercraft for shipment and for display and sale. More particularly, the shipping container of the present invention comprises a shipping container, comprising a pallet and a first pair of roller guides and a second pair of roller guides attached in spaced apart relation intermediate opposing ends of the pallet. Each of the roller guides comprises a pair of spaced-apart plates, a shaft extending between the plates, and a sleeve received on the shaft for axial rotation. A pair of trusses are each removably received on a respective one of the roller guides of the first pair of roller guides and the second pair of roller guides, whereby the trusses are movable on the respective sleeves that rotate during movement of the truss between a first position for loading or unloading the personal watercraft seated on the trusses and a second position for storing and transporting of the personal watercraft thereon.
In another aspect, the present invention provides a method of containing a personal watercraft in a shipping container for storage and shipping, comprising the steps of:
(a) providing a pallet having a first pair of roller guides and a second pair of roller guides, the first pair and the second pair of the roller guides attached in spaced apart relation intermediate opposing ends of the pallet, each of the roller guides comprises a pair of spaced-apart plates, a shaft extending between the plates, and a sleeve received on the shaft for axial rotation;
(b) placing one of a pair of trusses on a respective one of the first pair of roller guides and the second pair of roller guides in a first position for loading or unloading the personal watercraft thereon, the trusses movable on the sleeves from the first position to a second position for orienting a transverse axis of the personal watercraft at an oblique angle relative to the pallet for storing and transporting of the personal watercraft seated on the trusses; and

Objects, advantages, and features of the present invention will become apparent upon a reading of the following detailed description in conjunction with the drawings and the appended claims.
With reference to the drawings in which like parts have like identifiers throughout the several views,
The pallet 12 includes spaced-apart elongated outer members 20 and inner members 21 connected by transverse members 22 to define a rigid base. The members in the illustrated embodiment are elongate steel tubes that weld together to form the pallet 12. An open end tube attaches as receiver 37 at respective outside distal corners of the pallet 12. As illustrated in
With continuing reference to
The hull cradles 14 each include a pair of guides 26, 28 and a truss 30 for supporting the watercraft. The respective guides 26, 28 for the hull cradle 24 are positioned relative to the pallet 12 in transverse alignment and spaced apart, preferably on opposing sides of a longitudinal axis of the pallet. The truss 30 travels on the guides 26, 28 to move between a first position and a second position. The truss 30 in the first position enables loading of the personal watercraft 16 onto the truss and for unpacking of the personal watercraft from the shipping container. The truss 30 in the first position orients the transverse axis 33 of the personal watercraft 16 parallel to the pallet 12 for loading of the personal watercraft onto the shipping container and for unpacking of the personal watercraft from the shipping container. The truss 30 in the second position enables storage and shipping of the personal watercraft 16. The truss 30 in the second position orients the transverse axis 33 of the personal watercraft 16 at the oblique angle 35 relative to the pallet 12 for storage and shipping.
For the intermediate hull cradle 24b, the guide 26 mounts to a transverse member 31 extending between opposing inner members 21 of the pallet 12, or alternatively depending on size of the watercraft, between one of the inner members 21 and the adjacent outer member 20. For the aft hull cradle 24a, the guide 26 attaches to one of the transverse members 22. The guide 26 mounts between a central longitudinal axis of the pallet and the inner member 21 on a first side of the pallet. In the illustrated embodiment, the guides 26 attach closer to a longitudinal axis of the pallet 12 than to the lateral outer extent of the pallet. At least one stop member 32 extends upwardly from the inner member 21 proximate one of the guides 26 to a free distal end 34. The stop member 32 defines a stop at the distal free end 34.
On the opposite side of the pallet 12, a pair of transverse members 40 connect to the other outer member 20 and the adjacent opposing inner member 21. The pair of transverse members 40 are provided for each of the guides 28. The guide 28 attaches to the transverse members 40. This positions the guide 28 on the opposing side of the pallet 12 intermediate the longitudinal axis and the other outer member 20. In the illustrated embodiment, the guides 28 mount closer to the lateral outer extent than to the longitudinal axis. The guide 28 may be positioned vertically higher than the guide 26. An alternate embodiment may use one member 40 for each guide 28.

With returning reference to
Each truss 30 comprises an arcuate rail 60 and a spaced-apart chock 62 connected by at least one spans 64. The chock 62 rigidly connects 68 proximate the distal end portions to respective ends of the rail 60. A resilient pad 66 attaches to the chock 62 for cushioning the contact of the hull of the personal watercraft 16 with the truss 30. The chock 62 conforms in shape to a transverse cross-sectional exterior portion of the hull of the personal watercraft 16. The hull of the watercraft 16 thereby seats on the pad 66 for cushioned support on the truss 30. The chock 62 includes distal end portions 63 that extend at an angle. The distal end portions 63 thereby extend alongside a respective side wall of the watercraft 16 when positioned on the truss 30. An end of the distal end portion 63 bears on the stop 34 of the stop member 32 when the truss 30 moves to the first position.
The arcuate rail 60 in the illustrated embodiment has a 17 inch radius to an inner diameter and an 18 inch radius to an outer diameter. The resilient pad 66 is a cross-linked polyethylene foam (certified for Class A surface contact), of about 4 pounds per cubic foot density volumetric weight, or other suitable cushion material to restrict scratching or surface damage to the hull of the watercraft during transport and handling.
The pallet 12 of the shipping container 10 holds the watercraft 16 for storage and shipping.
Typically, the handle bar and a side rear-view mirror (depicted in broken line in

The watercraft 16 is then secured to the pallet 12. As illustrated in
With reference to
The secured watercraft 16 crated in the shipping container 10 may then be handled, such as by fork lift, for warehouse storage, or placed in a trailer for transport to a retailer.
At delivery to a retailer, the watercraft 16 is unpackaged from the shipping container 10. With reference to
The travel surface of the truss preferably readily moves easily relative to the guides 26, 28, such as for example low coefficient of friction between the rail 60 as a sliding portion of the hull supporting truss and the rotating sleeve 50 of the guide members. Alternate embodiments may use a curved plywood member for the travel contact surface and the guides may have surfaces on which the travel contact surface slides, for example, plastic shims.
The foregoing discloses an illustrative embodiment of a shipping container readily usable in trucking to remote retailers of personal watercraft mounted at an angled orientation relative to a pallet of the shipping container while facilitating the handling of the personal watercraft in a horizontal orientation for uncrating of the watercraft for display and sale.
