Description
- The present invention relates generally to open top shipping containers and, more particularly, to open top shipping containers for transporting goods via cargo ships or trucks.
- Shipping containers are used to hold goods such that the goods may be transported by both cargo ships and trucks. Open top shipping containers are known and have an open roof such that large goods that are not readily transported using a forklift may be loaded into the shipping container using a crane or the like. Such goods include, for example, building and construction material, such as steel, glass, and granite. Upon loading of the open top shipping container, a removable soft top assembly is installed over the open roof of the shipping container to provide protection to the goods from inclement weather and wind blown water.
- Frequently, upon reaching a delivery destination, the open top containers are returned or shipped to another location in an empty, unused state as they are not favorable for use with dry goods, such as electronics, certain manufactured items, and textiles. This is due to the inability of open top containers with soft top assemblies to provide adequate security to the goods from theft and tampering, or to adequately protect the goods from inclement weather and water damage.
- Shipping or transporting empty open top containers to points where they can be reused results in added expense by reducing the amount of cargo that a given ship may transport and/or by causing trucks to travel between locations without moving goods. Therefore, a means of shipping is desired that substantially eliminates the inefficiencies associated with transporting empty open top containers.
- The present invention provides an open top shipping container having a removable hard top assembly that enables the open top shipping container to be used to transport goods requiring added protection from theft, tampering, inclement weather, and water as compared to conventional soft top assemblies.
- According to an aspect of the present invention, a shipping container comprises a floor, first and second side walls, and a hard top assembly that includes a panel supporting element at or near an upper region of each side wall and a plurality of removable rigid cover panels. The cover panels are received and supported by the panel supporting elements. The cover panels are installed in adjacent relationship such that the first end of a given cover panel engages the second end of an adjacent cover panel.
- The removable cover panels of the hard top assembly of the present invention are readily assembled or mounted or installed at an open top shipping container and may be used alone or together with a conventional soft top assembly. The removable hard top assembly includes multiple cover panels that are generally light in weight and readily handled and, when not in use, may be readily transported. Optionally, the side regions or edges of the cover panels may be configured for sliding insertion into tracks or channels affixed to the side walls of the shipping container. The ends of the cover panels may also be constructed to engage the ends of adjacent cover panels in an overlapping and/or interlocking manner to provide further security and weather resistance to removable hard top assembly.
- According to another aspect of the present invention, a method of selectively covering a shipping container includes providing a shipping container, side panel supporting elements along said side walls, and a plurality of removable rigid cover panels. The shipping container includes a floor, opposite side walls, and first and second ends. Each of the cover panels has first and second side edges and first and second ends, and the cover panels are configured to be removably supported by the side panel supporting elements in adjacent relationship. A first cover panel is inserted along the side panel supporting elements such that the side panel supporting elements at least partially receive the first and second side edges of the first cover panel. A second cover panel is inserted along the side panel supporting elements such that the side panel supporting elements at least partially receive the first and second side edges of the second cover panel. The cover panels are moved along said side panel supporting elements until the first end of the second cover panel engages the second end of the first cover panel, such that the cover panels are supported by the side panel supporting elements in adjacent relationship.
- Optionally, the shipping container includes a movable header element between the opposite side walls and proximate an upper region of the second end of the shipping container. The header element is moved into an open position before insertion of the cover panels such that the side panel supporting elements are adapted to receive the side edges of the cover panels. The header element is moved into a closed position after insertion of the cover panels to limit retraction of the cover panels from the side panel supporting elements.
- Optionally, the method may include uncovering the shipping container. Uncovering the shipping container may include moving the header element into an open position such that the panel supporting elements and the cover panels are readily accessible. The cover panels are moved along the panel supporting elements and the cover panels are removed from the side supporting elements, after which the header element, if included, may be moved to a closed position.
- Therefore, the open top shipping container of the present invention may be used to transport large, bulky goods that must be loaded through the open roof of the shipping container. The present invention enables the shipping container to be used to transport such goods, as well as other types of goods that typically must be transported in a more secure or protected manner than the manner provided by use of only a conventional soft top assembly. Furthermore, the removable hard top assembly of the present invention and the soft top assembly may both be installed to the shipping container such that added protection is provided to goods being shipped within the shipping container. In situations where the components of the hard top assembly are not used, however, the cover panels may be conveniently handled and stacked within the shipping container while occupying a limited amount of space.
- These and other objects, advantages, and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.

FIG. 20 is an end elevation and partial sectional view similar toFIG. 12 , showing an open top shipping container having the hard top assembly installed beneath the soft top assembly and including the bracket-mounted track or channel ofFIG. 15 . - The present invention will now be described with reference to the accompanying figures, wherein the numbered elements in the following written description correspond to like-numbered elements in the figures. An open
top shipping container 20 is shown inFIG. 1 mounted to adelivery vehicle 22, with the removable roof assemblies described below removed from theshipping container 20, such thatgoods 24 may be loaded or lowered into theshipping container 20 through theopen roof 26. As shown inFIG. 2 , a removable hard top assembly orrigid cover assembly 28 may be installed or attached to and along the side walls of the shipping container so as to substantially close and/or seal the open roof or top of the shipping container, as discussed below. The removablehard top assembly 28 includes multiple panel sections orrigid cover panels 30 that may be removably installed at least partially within and along tracks or channels which are mounted to theshipping container 20. When thecover panels 30 are installed anddoor assembly 32 is closed, theshipping container 20 is substantially sealed and access to the interior ofshipping container 20 is substantially prohibited. The removablehard top assembly 28 thus provides protection to the contents withinshipping container 20 in the form of security from theft and tampering, and protection from inclement weather, such as driving wind and water. - Open
top shipping container 20 may be provided with a conventional removable soft top assembly orflexible cover assembly 34, such as illustrated inFIGS. 3 and 4 . The softtop assembly 34 includes multiple support members or bows orrods 36 and a flexible top element or member or tarp orcover 38. Opentop shipping container 20 may be selectively provided or used with either the removable hardtop assembly 28 or the removable softtop assembly 34. Notably, the removable hardtop assembly 28 may also be simultaneously used with the removable softtop assembly 34. For example, and as shown inFIGS. 4 , 5, 11, 12, 19, and 20, thecover panels 30 of hardtop assembly 28 may be installed beneath thesupport members 36 andtop member 38 of softtop assembly 34. Opentop shipping container 20 may thus be used to shipbulky goods 24, such as building and construction materials, that are loaded through theopen roof 26 and may also be used to ship various smaller dry goods, such as manufactured items and textiles, which must be protected from theft and tampering, as well as from moisture. The hard top assembly and/or soft top assembly is/are selectively attached to the shipping container depending on the particular application of the shipping container and the goods being shipped therein. - In the illustrated embodiment, open
top shipping container 20 includes afloor 40, opposite first andsecond side walls FIG. 6 ) and adoor assembly 32 opposite theend wall 46. The first andsecond side walls end wall 46, anddoor assembly 32 may be of a painted or coated corrugated steel construction for strength and corrosion protection. First andsecond side walls beam 48 and, in like manner, an upper rail orbeam 50 is also provided onend wall 46. As shown inFIGS. 11 and 19 , theupper rails 48 of first andsecond side walls FIGS. 12 and 20 , theupper rails 48 for the first and second side walls may be substantially rectangular or square shaped beams, and may also be used to support an end wall. Although not shown, theupper rail 50 ofend wall 46 is also of like construction. -
Door assembly 32 comprises two pivotally mounteddoors doors 52 a pivotally mounted toshipping container 20 adjacent tofirst side wall 42 and theother door 52 b pivotally mounted adjacent tosecond side wall 44 as shown inFIGS. 2-4 , 9, and 10.Door assembly 32 also includes a header or beam 54 (FIGS. 2-5 , 9, 10, and 18) extending between first andsecond side walls Beam 54 is movably or removably mounted atshipping container 20, and may be removable fromshipping container 20 or may pivot or otherwise move with respect to either ofdoors door assembly 32, so as to allow for loading and unloading of goods and to allow for insertion and removal of the cover panels as discussed below. - It should be understood that alternative open top shipping containers may be constructed in accordance with the present invention. For example, in the illustrated embodiment, first and
second side walls end wall 46 are immovable relative tofloor 40. However, an alternative open top shipping container may be constructed with side walls that are removable from the floor or are pivotally connected to the floor such that they may be lowered or moved or removed for further improved loading. The end wall may also be constructed to be removable or pivotal, or may be constructed as a second door assembly, such as a door assembly similar todoor assembly 32, discussed above. Also, although shown with adoor assembly 32opposite end wall 46, the open top shipping container may optionally have a second end wall opposite theend wall 46. Other variations todoor assembly 32 may include, but are not limited to, one or more doors pivotally or otherwise movably mounted toshipping container 20 adjacent one or more of the side walls, the header, or the floor, whereby the door or doors may pivot about either a horizontal pivot axis or vertical pivot axis or may otherwise move relative to the end of the shipping container to open the end of the container, while remaining within the spirit and scope of the present invention. It is further envisioned that theheader 54 may be incorporated into the door or doors of the door assembly, and may pivot or move (or may be removed) with the door or doors of the door assembly, while remaining within the spirit and scope of the present invention. Furthermore, the open top shipping container may also be constructed of alternative materials and, while typically constructed to have a length of twenty or forty feet, may be constructed of alternative lengths, widths, and heights. - As noted above, removable hard
top assembly 28 is constructed ofmultiple cover panels 30. Arepresentative cover panel 30 is illustrated inFIG. 13 and includes first and second ends or endedges cover panels 30 having awidth 64 of approximately 85 inches (or other width depending on the width of the container and separation distance of the tracks or channels) and alength 66 of approximately 30 inches or other lengths as may be desired.Cover panels 30 may be constructed of a corrugated metallic material and may include a corrosion inhibiting protective coating, with the corrugated design providing a relatively light weight and strong construction.Cover panels 30, for example, may be constructed of GALVALUME® provided by BIEC International, Inc. of Vancouver, Wash. - Although illustrated as being corrugated and constructed of a coated metallic material, it should be understood that
cover panels 30 may be alternatively constructed while remaining within the scope of the present invention and while still functioning as intended. For example, cover panels may be constructed of different widths and/or lengths depending upon the size of shipping container to which they will be installed. The cover panels may also be constructed of any suitable material, such as a plastic material or composite material, or may be constructed of generally flat materials as opposed to being corrugated while remaining within the spirit and scope of the present invention. - As previously noted,
cover panels 30 are removably installed within panel supporting elements or receiving elements, such as first and second side tracks 68, 70 (FIGS. 8-12 , 17, 19, and 20), end track 72 (FIGS. 7 , 8, and 17), and door track 74 (FIG. 9 ), all mounted at or near an upper region of therespective side walls end wall 46, anddoor assembly 32. In the illustrated embodiment, first and second side tracks 68, 70,end track 72, anddoor track 74 are constructed of a substantially U-shaped or C-shapedchannel 76. As shown inFIG. 11 , the base of thechannel 76 of first andsecond tracks upper rail 48 of first andsecond side walls Channel 76 ofend track 72 andchannel 76 ofdoor track 74 are similarly mounted (as shown inFIGS. 7 , 8, and 9). When the channels of the tracks are mounted to the respective upper rail or header, the openings of thechannels 76 are all directed generally inwardly toward the center ofshipping container 20. Alternatively constructed tracks and/or channels may also be used, such as, for example, tracks having a generally “T” or “L” shaped profile, depending on the shape or configuration of the cover panels. - Optionally, the panel supporting elements or channels may terminate a substantial distance, such as about 12 inches or more, from an end of the open top shipping container in order to allow installation of the cover panels at the top region of
shipping container 20. For example, the channels may terminate 12 inches or more from the end of the container at the door assembly, whereby the cover panels may be inserted into and removed from the channels and through the open doors, without having to move or remove the header at the door end of the container. Optionally, it is further envisioned that a gap between two side panel supporting elements along respective side walls of the shipping containers may be established, whereby one or more cover panels may be inserted in both directions into and along the respective side panel supporting elements or channels so that the cover panels may be installed and uninstalled from substantially within the shipping container. For example, two side channels may be provided along each side wall and separated by a gap of about 12 inches or more, and one or more cover panels may be inserted at the gap into the respective opposite side channels in one direction, while one or more cover panels may be inserted at the gap into the respective opposite side channels in the other direction to close ore at least partially cover the open top shipping container. - Optionally,
channels 76 may be constructed of any suitable material, such as a coated metallic material, or a plastic material or a composite material or the like.Channels 76 may be secured to theupper rails door header 54 using fasteners, such as screws or bolts, and/or may be affixed or secured to the rail or header with an adhesive or the like, or may be welded to the rail or header or walls of the shipping container. Optionally, the panel supporting elements or channels may be integrally formed with and at least partially along the upper rails and/or door header of a shipping container, and from at least partially within the shipping container, such as by rolling, molding, stamping, or embossing the channels along the inner side or surface of the rails and/or header, such as during the process that forms the rails and/or header. - Optionally, and as shown in
FIGS. 16 , 17, 19, and 20,channels 76 may be mounted to the shipping container via brackets 77 (FIG. 15 ), which may be welded or otherwise secured to the panels. Thebrackets 77 are removably connected to theshipping container 20 such as atupper rails FIGS. 16 , 17, 19, and 20. Optionally, a sealant may be disposed at or around the interfaces between thechannels 76 and/orbrackets 77 and theupper rails door header 54 to limit or substantially preclude moisture from entering into the interior of the coveredshipping container 20 during transport of the goods. - Optionally,
channels 76 may be provided with various structural formations to further prevent or direct water away from the interior ofshipping container 20, such as rolled lips or flanges 76 a, 76 b (FIGS. 15 and 16 ) at the end or open edge of each horizontal leg of thechannel 76. For example, the lower horizontal leg of thechannel 76 of side tracks 68, 70,end track 72, and/ordoor track 74 may be provided with a conduit, such as an indented groove or rolled lip 76 a (FIGS. 15 and 16 ), or the like, formed or established therealong, whereby any water entering into thechannels 76 may be directed or carried by the conduit to locations outside ofshipping container 20. Alternatively, or in addition thereto, one or more holes or passageways may be provided that extend from the base of the channels through and into the interior of theupper rails header 54 whereby water may be guided through the holes and substantially not into the interior of the container. Similarly, holes or passageways may be provided that extend from the lower horizontal leg of thechannels 76, whereby water may be similarly guided. -
Channels 76 of side tracks 68, 70 are configured to slidably receive the side edges of the cover panels as the cover panels are inserted into and moved along the side tracks. In the illustrated embodiment, coverpanels 30 are corrugated metal panels, whereby the side edges of the panels are formed in a corrugated or wave pattern. The side tracks 68, 70 receive the wave-shaped side edges of the cover panels, with an upper surface portion of the upper “wave” portions of the panel engaging an upper rail or portion of the track and with a lower surface portion of the lower wave portions of the panel engaging a lower rail or portion of the track. Optionally, the channel size may be selected to provide a snug fit of the corrugated side edges, and may frictionally retain the cover panels, and thus may limit free movement of the cover panels to reduce displacement of the cover panels and rattling of the cover panels during transport. The corrugated metal panels may flex or partially flatten as the panels are inserted into and along the channels of the tracks to provide the snug fit of the panels within and along the side tracks. Optionally, however, the channels of the side tracks may be sized so as to loosely receive the side edges of the cover panels, without affecting the scope of the present invention. The channels of theend track 72 anddoor track 74 may have a lower profile than the channels of the side tracks, since the end track and door track are configured to receive the substantially flat end edges of the end cover panels positioned at the ends of the shipping container. However, other shaped cover panels and other types or sizes of tracks or channels may be implemented at the shipping container while remaining within the spirit and scope of the present invention. - As previously noted,
cover panels 30 are adapted for sliding insertion into first andsecond tracks end track 72, anddoor track 74. For example, and as shown inFIG. 2 , hardtop assembly 28 may includemultiple cover panels 30 supported along the container with anend cover panel 78 being installedproximate end wall 46 and anend cover panel 80 being installedproximate door assembly 32, with a plurality of cover panels positioned betweenend cover panels - When it is desired to close the top of
shipping container 20, thecover panels 30 may be slid or installed in and along the channels of the tracks. To assemble hardtop assembly 28 toshipping container 20,header 54 is initially removed or pivoted or moved into an open position such that first andsecond tracks End cover panel 78 is then inserted into first andsecond tracks first side edge 60 ofend cover panel 78 is positioned withinfirst track 68 andsecond side edge 62 is positioned withinsecond track 70.End cover panel 78 may then be moved along or slid within first andsecond tracks shipping container 20 untilfirst end edge 56 engages and is received in or contained withinend track 72 atend wall 46. - Next, a
second cover panel 30 is inserted into first andsecond tracks end cover panel 78, such that thefirst side edge 60 is withinfirst track 68 and thesecond side edge 62 is within second track 70 (FIG. 11 ). Thecover panel 30 is then slid the remaining length ofshipping container 20 until thefirst end edge 56 of thesecond cover panel 30 being installed engages thesecond end edge 58 of theend cover panel 78, previously installed. Such engagement may provide an interlocking or overlapping engagement such as discussed below. The above installation steps are then repeated for the remainingcover panels 30 until the lastend cover panel 80 is installed, with thesecond end edge 58 of theend cover panel 80 being located proximate the end of the shipping container withdoor assembly 32. After theend cover panel 80 is installed,header 54 may be moved to its closed position or reinstalled at the end to retain the cover panels and limit or substantially preclude retraction of the cover panels from the tracks or channels. Whenheader 54 is reinstalled or pivoted or moved back into the closed position, thedoor track 74 ofheader 54 engages or receives thesecond end edge 58 of theend cover panel 80 such that all of thecover panels 30 are securely held within and mounted toshipping container 20. Optionally, and such as for an embodiment where the channels terminate a substantial distance from an end of the open top shipping container, theend cover panel 80 may be held or secured after installation via other means, such as via fasteners connecting theend cover panel 80 to the tracks or channels, or to the side walls or header or the like. - Although
header 54 is shown as being pivotally mounted at the end of the shipping container, any movable or removable member or element that will substantially prevent removal ofcover panels top shipping container 20opposite end wall 46. For example, such elements may include one or more locking pins, bars, straps, fasteners, or the like, such as at the ends of the tracks or at the ends of the side walls, or the doors may extend upward whereby the top portions of the doors may cover or close the ends of the track or otherwise limit removal of the cover panels within the tracks. When it is desired to remove the cover panels, the stop element or elements may be selectively opened or moved, such as by pivoting at a top, bottom, or side edge, or by sliding or by otherwise disengaging from the area proximate thesecond end edge 58 ofend cover panel 80 whenend cover panel 80 is installed, in order to permit removal ofcover panels top shipping container 20. Additionally, such elements may include, for example, one or more fasteners that fixend cover panel 80 totracks side walls shipping container 20. - Notably, the engaging of the first or
second end edge cover panel 30 with the second orfirst end edge adjacent cover panel 30 may be accomplished in an overlapping and/or an interlocking relationship. An overlap may be obtained by merely passing a flat section of oneend edge engaged end edge adjacent panel 30. This overlap may also serve to interlock theadjacent cover panels 30 by wedging thecover panels 30 into a pressed engagement with the C-shapedchannel 76. Optionally, an alternative overlap and interlock may also be accomplished by overlapping one or more of the corrugated ridges or troughs of onecover panel 30 with one or more of the corrugated ridges or troughs of anadjacent cover panel 30. Optionally, and as shown inFIG. 18 , the end edges 56, 58 of thecover panels 30 may be constructed to form interlockingmembers members member 56 a of a first cover panel may overlap and then engage and interlock with interlockingmember 58 a of an adjacent cover panel in an interlocking relationship to substantiallysecure cover panels 30 together and protect against entry and water intrusion and other weather conditions. Optionally, the various end edges of the cover panels may be constructed to include interlocking members for receiving adjacent end edges, such as elastomeric grommets or the like, to thereby form an interlocking relationship. Optionally, the overlapping end edges ofadjacent cover panels 30 may be secured together using fasteners such as screws, bolts, clips, rivets, or the like, to provide a substantially secure engagement. Optionally, one or more fasteners may be used to secure first and second side edges 60, 62 ofcover panels 30 within first andsecond tracks - To uncover or open the top of
shipping container 20, such as for loading or unloading the shipping container, the steps of coveringshipping container 20 may be substantially followed in reverse order. Briefly, theheader 54 may be moved or removed or opened (and/or fasteners may be released from the end cover panel) to allow for removal of the end cover panel. Thefirst end 56 ofend cover panel 80 is then disengaged fromsecond end 58 ofadjacent cover panel 30 and removed fromchannels 76.Subsequent cover panels 30 are moved alongchannels 76 and removed in a similar manner, ending withend cover panel 78, after which theheader 54 may be closed ore reinstalled as desired. - As previously noted, open
top shipping container 20 may also be provided with a standard or conventional softtop assembly 34 comprisingsupport members 36 and atop member 38. Thesupport members 36 extend transversely acrossshipping container 20 and are mounted to theupper rails 48 of first andsecond side walls second tracks 68, 70 (FIG. 11 ). Thesupport members 36 are used to support the flexible top member 38 (FIGS. 16 and 17 ), which may be secured to the side walls or rails of the sides walls when pulled substantially taut over the support members, such as via tie downs or hooks and grommets or the like. The flexible top member may comprise any suitable flexible material, such as canvas or a polymeric material or the like. However, it should be appreciated that an alternative shipping container may be constructed for use only with hard top assembly and thus not include soft top assembly, while remaining within the spirit and scope of the present invention. - Therefore, the open top shipping container of the present invention may be used in a conventional manner to transport large, bulky goods, such as building and construction materials, that must be loaded through the open roof of the shipping container. The removable hard top assembly of the present invention enables the shipping container to be used to transport such goods, as well as other types of goods, such as manufactured items, electronics, textiles, and the like, that typically must be transported in a more secure or protected manner than the manner provided by use of only a conventional soft top assembly. Furthermore, the removable hard top assembly of the present invention and the soft top assembly may both be installed to the shipping container such that added protection is provided to goods being shipped within the shipping container and, notably, no additional space is required for transporting unused components of the hard and soft top assemblies. In situations where the components of the hard top assembly are not used, however, the cover panels may be conveniently handled and stacked within the shipping container while occupying a limited amount of space.
- Changes and modifications in the specifically described embodiments can be carried out without departing from the principles of the present invention which is intended to be limited only by the scope of the appended claims, as interpreted according to the principles of patent law including the doctrine of equivalents.
