Abstract
Description
- This application claims priority from, and incorporates by reference the disclosure of, U.S. Provisional Patent Application No. 60/714,756, which was filed on Sep. 6, 2005.
- 1. The Technical Field
- The present invention is directed generally to collapsible containers and more particularly to collapsible shipping and storage containers and methods of using same.
- 2. The Prior Art
- Known shipping and storage containers typically have fixed dimensions and occupy the same physical volume whether full or empty. Although this shortcoming is tolerable when the containers are in use, it adversely affects the cost of storing or transporting the containers when empty. Prior attempts to reduce the volume of an unused container typically involve dismantling the container by removing the sides, ends, and top, and stacking these pieces on the bottom. Such dismantling is labor intensive and time consuming, requires substantial rigging, and yields a number of easily lost and essential loose parts, e.g., the fasteners used in assembling the sides, ends, top, and bottom of the container. As such, there is a need for containers that are sufficiently robust to handle the rigors of shipping and storing voluminous and/or heavy cargo but can be easily and quickly broken down to a self-contained, compact form for storage or transport when empty.

FIGS. 1-3 illustrate a foldable container according to a preferred embodiment of the present invention in deployed, partially-collapsed, and collapsed states, respectively.Foldable container 10 includesfloor 12,roof 14,side walls rear wall 20, andfront end 22. Each ofside walls upper portion lower portion upper side walls side walls lower side walls side walls Roof 14,side walls rear wall 20 typically include askin 24R,24SW,24RW, respectively, that protects the contents ofcontainer 10 from the elements and provides a barrier to unauthorized access to the interior ofcontainer 10. -
Front end 22 typically is configured to provide access to the interior ofcontainer 10. Preferably,container 10 includesoverhead door 26 that can be moved between a first, deployed position whereindoor 26 closes an opening defined byfront end 22 ofcontainer 10 and a second, retracted position whereindoor 26 nests with or withinroof 12, as will be described further below. In preferred embodiments,door 26 is made from roll-formed metal sheeting as would be used to make a conventional metal roll-up door. Such doors are commonly used on the rear of delivery trucks and in connection with concession service windows at sports stadiums. In alternate embodiments,door 26 can be a conventional single- or multi-panel overhead door (not shown) that may or may not include a swinging service door (not shown), as would be known to one skilled in the art. In other alternate embodiments,door 26 can retract intofloor 12.Front end 22 anddoor 26 can be embodied in other forms as well, as would be apparent to one skilled in the art. Means (not shown), such as an integral locking mechanism or hasp for receiving a padlock, can be provided for securingdoor 26 in a “closed” position to preclude unauthorized access to the interior ofcontainer 10. -
FIGS. 4-6 illustrate the framework 30 ofcontainer 10 in partially-deployed and deployed states, respectively, according to a preferred embodiment of the present invention. In this embodiment, framework 30 includesfloor frame 32, roof frame 34, side wall frames 36,38,rear wall frame 40, andfront end frame 42. Each of side wall frames 36,38 includes anupper portion lower portion -

In the illustrated embodiment, hinge pins 72 are used to connectrear wall frame 40 tofloor frame 32. Alternative embodiments can use any other suitable hinge mechanism, for example, conventional leaf-type hinges, as would be known to one skilled in the art. -
Front end frame 42 includes aperimeter rim 96 that defines the top and sides offront end frame 42. Perimeter rim 96 includestop member 98 and a pair ofcolumns 100 extending fromtop member 98.Front end frame 42 can further include one or more cross-members (not shown) and braces and/or stiffeners (not shown) for strength, as would be known to one skilled in the art. Any such additional members preferably are located so as to not impede access to the interior of, or create a trip hazard within or near the entry of,container 10. -
Front end frame 42 preferably is hinged tofloor frame 32 so thatfront end frame 42 can be folded inwardly and substantially flatly against the top offloor frame 32 whencontainer 10 is in the collapsed state and unfolded so thatfront end frame 42 is substantially perpendicular tofloor frame 32, roof frame 34, and side wall frames 36,38 whencontainer 10 is in the deployed state. In the preferred embodiment, hinge pins 74 are used to connect the lower ends ofcolumns 100 offront end frame 42 tofloor frame 32. Alternative embodiments can use any other suitable hinge mechanism, as would be known to one skilled in the art. In preferred embodiments,front end frame 42 includes door tracks 76 (seeFIG. 6 ; door tracks 76 have been omitted from the other drawings for clarity) which receive the side edge portions ofdoor 26 whendoor 26 is positioned in and moved to and from the deployed position, as shown inFIG. 1 . - In preferred embodiments, stop
plates 104 are provided at both ends of framework 30 in connection with roof frame 34 and the upper and lower portions of side wall frames 36,38 to prevent rotation ofrear wall frame 40 andfront end frame 42 more than about 90 degrees from the collapsed position againstfloor 12 so thatrear wall frame 40 andfront end frame 42 can be easily indexed to their respective deployed positions. In such embodiments, stopplates 104 preferably are connected to columns 64 defining the ends of the upper and lower portions of side wall frames 36,38 and the ends of perimeter rim 48 of roof frame 34. Gasket material (not shown), for example, conventional weatherstrip, can be provided in connection withstop plates 104 to provide a form of seal between roof frame 34, side wall frames 36,38,rear wall frame 40 andfront end frame 42. Gasket material (not shown) also can be provided in connection with the joints betweenfloor 12 andrear wall frame 40,floor 12 and lower side wall frames 36L,38L, lower side wall frames 36L,38L and upper side wall frames 36U,38U, and upper side wall frames 36U,38U and roof frame 34. Further, gasket material (not shown) can be provided at the bottom ofdoor 26, adjacent the side ofdoor 26 and door tracks 76, and alongtop member 98 offront end frame 42 to form a seal betweendoor 26,floor 12,front end frame 42, andside walls door 26 is in the closed position. - In other embodiments, either or both of
rear wall frame 40 andfront end frame 42 can be completely detachable fromfloor frame 32, and hingepins 72 and/or hinge pins 74 (or other, alternate hinge means) can be omitted. In such embodiments,rear wall frame 40 andfront end frame 42 can be connected tofloor frame 32, roof frame 34, and/or side wall frames 36,38 by threaded fasteners or other suitable means whencontainer 10 is in the deployed state and stored againstfloor 12 whencontainer 10 is in the collapsed state. - One or more lifting lugs 106 can be provided to facilitate deployment and collapsing of
container 10 using a crane or other lifting mechanism (not shown). Such lifting lugs preferably would be attached to roof frame portion 34 using fasteners or welded connections but, alternatively, could be attached to other portions of framework 30 by any suitable means. - The detailed design of
container 10 and framework 30 as illustrated in the drawings and discussed above is representative, but by no means limiting. One skilled in the art would recognize that that the detailed design for a particular collapsible container according to the present invention is a function of, among other factors, the size of and intended use for the container. One skilled in the art would know how to size and arrange the members (e.g., perimeter rims, joists, rafters, columns, stiffeners, braces, etc.) used to build the various frame portions, select appropriate materials (e.g., tube steel, angle iron, and steel channel) for such members, specify connection details (e.g., brackets, hinge mechanisms, etc.), and specify connection methods (i.e., bolting, welding, etc.). - With
container 10 in the deployed state, as shown inFIGS. 1 and 5 , upper andlower side walls floor 12 androof 14 and coextensive with each other.Rear wall 20 andfront end 22 are substantially perpendicular tofloor 12,roof 14, andside walls rear wall frame 40 andfront end frame 42 are at least loosely engaged with interior portions of roof frame 34 and side wall frames 36,38, as best shown inFIG. 5 , so as to inhibit collapse ofroof 14 andside walls - In preferred embodiments, as best shown in
FIG. 6 , corresponding pairs ofapertures 78 are provided in adjacent portions of roof frame 34, upper and lower side wall frames 36U,38U and 36L,38L, respectively,rear wall frame 40 andfront end frame 42 to enable use of fasteners, for example,bolts 80, to interconnect such frame portions whencontainer 10 is in the deployed state. (In practice, more or fewer pairs ofapertures 78 than shown inFIG. 6 may be provided.) For example, one ormore bolts 80 preferably are inserted through corresponding pairs ofapertures 78 in adjacent portions of the foregoing frame members to secure perimeter rim 48 of roof frame portion 34 to perimeter rim 58U of upperside frame portions rear frame portion 40, and perimeter rim 96 offront frame portion 42. Similarly, one ormore bolts 80 can be used to secure perimeter rim 56U of upperside frame portions side frame portions FIG. 6D ), and one ormore bolts 80 can be used to secure perimeter rims 56U,56L of upper and lowerside frame portions perimeter rim 86 ofrear frame portion 40 and perimeter rim 96 offront frame portion 42. - Preferably,
bolts 80 engage withcaptive nuts 82 associated with oneaperture 78 of each of such corresponding pairs ofapertures 78. Loose nuts (not shown) can be used in lieu ofcaptive nuts 82, butcaptive nuts 82 are preferred because they are permanently affixed, for example, welded as bridge weld nuts, to framework 30 and thus do not contribute to the inventory of loose parts (including, e.g., certain bolts 80) that must be controlled whencontainer 10 is in the collapsed state.Apertures 78 can be configured so thatbolts 80 are inserted through members to be joined in their entirety. For example, as shown inFIG. 5 ,bolts 80 extend through the entirety ofbottom member 60U of upperside wall frame 38U andtop member 62L of lowerside wall frame 38L and are fastened to captive nuts 82 (or a loose nut) on the bottom surface oftop member 62L of lowerside wall frame 38L. In embodiments where at least one of the members to be fastened together has a hollow cross-section (e.g., tube steel),captive nuts 82 preferably are fitted on the inside of such member so thatbolt 80 need not extend through the entirety of such member. In all embodiments, bolt 80 preferably is installed into the members to be connected from the interior ofcontainer 10 to preclude tampering withbolt 80 from the exterior ofcontainer 10. - Although threaded fasteners are preferred for the foregoing mechanical connections, various other forms of fasteners, including quick release fasteners, can be used in lieu of threaded fasteners in certain embodiments, as would be known to one skilled in the art.
- Preferred embodiments also include a coupling associated with pairs of corresponding columns 64U,64L of upper and lower side wall frames 36U,38U and 36L,38L, respectively, which helps to secure the upper and lower side wall frames 36,38 in the deployed position.
FIGS. 6, 6B , and 6C illustrate one such embodiment wherein columns 64U,64L are members, such as tube steel, having hollow cross sections andcoupling 84 is a member, such as steel bar stock or tube steel, sized to fit within columns 64U,64L in sliding engagement.Coupling 84 is movable between a first, retracted position, whereincoupling 84 is engaged with column 64L, but not column 64U, and a second, deployed position whereincoupling 84 is engaged with both column 64L and column 64U, thus inhibiting the collapse of upper and lower side wall frames 36U,38U and 36L,38L. - In preferred embodiments, coupling 84 includes a
handle 85 that extends throughslot 89 in column 64L. Preferably, handle 85 is a bolt threaded into and staked to a threadedaperture 87 in coupling 84 (or a bolt inserted through an unthreaded aperture incoupling 84 and threaded into and staked to a captive nut attached to coupling 84) so that handle 85 cannot be inadvertently removed fromcoupling 85.Slot 89 and handle 85 interact to define the extent to whichcoupling 84 can slide within columns 64L,64U. - In preferred embodiments, coupling 84 includes a number of
apertures 91 and corresponding captive nuts 83, and columns 64U,64L include a number ofapertures 78 that align withapertures 91 incoupling 84 when coupling 84 is in the deployed position.Coupling 84 can be secured in the deployed position by insertingbolts 80 throughapertures 78 in columns 64U,64L andapertures 91 incoupling 84 and threading them into captive nuts 83. Preferably, columns 64U,64L also include a number ofapertures 78 that align withapertures 91 incoupling 84 when coupling 84 is in the retracted position.Coupling 84 can be secured in the retracted position by insertingbolts 80 throughsuch apertures 78 in columns 64U,64L andapertures 91 incoupling 84 and threading them into captive nuts 83. One skilled in the art would recognize thatcoupling 84 and the means for securingcoupling 84 to columns 64U,64L could be modified in many ways. For example,apertures 91 incoupling 84 could be threaded and captive nuts 83 could be omitted. Apertures could provided to allowbolts 80 to extend through columns 64U,64L in their entirety and captive nuts could be provided with columns 64U,64L to securebolts 80 thereto. Alternatively, coupling 84 could be external to columns 64U,64L. - With
container 10 in the deployed state,door 26 can be readily moved between the retracted position, whereindoor 26 nests within roof frame 34, and the deployed position whereindoor 26 closes the opening defined byfront end 22. Guide rollers 56help door 26 transition between a substantially vertical orientation defined bydoor tracks 76 attached tofront end frame 42 and a substantially horizontal orientation defined bydoor tracks 54 attached to roof frame 34. -
Roof skin 24R preferably takes the form of a fiberglass shell overlying and connected to the exterior of roof frame 34, as shown in the drawings. Side wall skin 24SW and rear wall skin 24RW preferably take the form of rigid or semi-rigid panels, preferably made of high molecular weight polyethylene, the edges of which are received bychannels 108 associated with the members comprising at least portions of side wall frames 36,38 andrear wall frame 40. Alternatively, skins 24R,24SW,24RW can be made of any suitable rigid, semi-rigid, or flexible material and attached to the inside or outside of the corresponding frame portion using any suitable means, for example, adhesives, rivets, threaded fasteners, etc. - Preferably, one or more portions of side wall perimeter rim 58 and rear wall perimeter rim 86 are removable to allow replacement of sections of side wall skin 24SW and rear wall skin 24RW should they become damaged. For example, upper
side wall frame 36U preferably is configured so that top member 62 can be removed to allow replacement of corresponding side wall skin 24SW by sliding such skin in and out ofchannels 108. Preferably, top member 62 is attached to columns 64U using brackets (not shown) that are riveted to one of top member 62 and columns 64U and welded or otherwise attached to the other of top member 62 and columns 64U. Alternatively, such brackets can be riveted to both of top member 62 and columns 64U. Should side wall skin 24SW need replacement, such rivets (not shown) could be easily drilled out and replaced.Rear wall frame 40 andcorresponding skin 24R can be similarly configured. - A preferred procedure for placing
container 10 into the deployed state from the collapsed state involves attaching suitable rigging to liftinglugs 106 and a suitable lifting mechanism, for example, a crane or fork lift. The lifting mechanism then raisesroof 14, causing upper andlower side walls roof 14 and top offloor 12, respectively, to form substantially planar andvertical walls Couplings 84 are then moved from a retracted position within column 64L to a deployed position within both of columns 64L and 64U.Bolts 80 are inserted throughapertures 91 incoupling 84 andapertures 78 in corresponding portions of columns 64L and 64U and secured to captive nuts 83.Rear wall frame 40 andfront end frame 42 are then unfolded from positions adjacent and substantially parallel to the top offloor 12 to positions substantially perpendicular to each offloor 12,roof 14, andside walls plates 104 prevent over-rotation ofrear wall frame 40 andfront end frame 40 and help to indexrear wall frame 40 andfront end frame 40 to the desired orientation relative to 12,roof 14, andside walls Bolts 80 are inserted through corresponding pairs of apertures in the foregoing frame sections and fastened to captive nuts 82. The rigging can be safely removed oncecouplings 84 have been deployed and secured, but preferably remains in place until the previous step has been completed. Ifcontainer 10 includes foldableguide roller brackets 57, such brackets are moved to the deployed position.Door 26 then can be moved between its open and closed positions, traveling over guide rollers 56. - A preferred procedure for collapsing
container 10 essentially reverses the steps of the foregoing deployment procedure. That is,door 26 typically would be placed in the stored position within roof frame 34 and guideroller brackets 57, if foldable, then would be placed in the stored position. Next,bolts 80 would be removed fromapertures 78, except thoseapertures 78 through whichbolts 80 are secured to couplings 84. Next,rear wall frame 40 andfront wall frame 42 would be folded againstfloor 12.Bolts 80 securingrear wall frame 40 andfront wall frame 42 to side wall frames 36,38 and roof frame 34 could then be reinstalled in theapertures 78 from which they were removed and threaded intocaptive nuts 82 to reduce the risk of losingsuch bolts 80. Rigging would be installed before the next step, which involves loosening or removingbolts 80 securingcouplings 84, as necessary, to allowcouplings 84 to be moved to the retracted position within the corresponding columns 64L.Such bolts 80 then could be used to securecoupling 84 in the retracted position.Roof 14 then would be lowered by slackening the rigging connected to lifting lugs 106. It may be necessary to exert an inward force near hinges 70 joining upper and lower side wall frames 16U,16L and 18U,18L to initiate the folding ofwalls - This disclosure illustrates and describes one or more particular embodiments preferred by the inventors. One skilled in the art would recognize that various modifications could be made to embodiment(s) disclosed herein without departing from the scope of the invention, which is limited only by the following claims.
