INVENTORS I ALFRED PATRICK CHISWELL "a": MICHAEL LOMBARDI United States Patent 3,401,814 COLLAPSIBLE SHHPING CONTAINER Alfred Patrick Chiswell, Brooklyn, N.Y., and Michael Lombardi, Jackson, N.J., assignors to Collapsible Container Corp., Newark, N.J., a corporation of New Jersey Filed Mar. 7, 1967, Ser. No. 621,261 15 Claims. (Cl. 220-4) ABSTRACT OF THE DISCLOSURE A collapsible shipping container having a base frame supporting a decking panel, which inturn releasably supports elongated corner posts positioned complementally to limited vertically extending peripheral corner walls of the base frame. The base frame includes channels for supporting side panels which abut flange members of the corner posts and which are detachably connected thereto, and which together support in complementary releasable engagement a roof frame having limited downwardly extending walls forming .a roof channel. A door panel completes the assembly and is locked from the outside. When collapsed, the base frame and the roof frame complementally engage, defining a reduced space therebetween, in which the corner posts and panels are disposed.

The present invention relates to shipping containers in general, and to collapsible shipping containers, in particular.

Collapsible shipping containers are known which have a predetermined volume capacity to receive products for shipment therein, and which are adapted to be dissambled and collapsed to a substantially reduced volume capacity for return shipment.

It is one object of the present invention to provide an improved collapsible shipping container which may be made of larger size and for carrying heavier loads, than heretofore, and providing an exceptionally high weight to volume strength ratio.

It is another object of the present invention to provide a collapsible shipping container which is preferably at least partly extrusion formed and uniquely adapted to provide exceptional advantages of durability, rapid assembly, and disassembly, interchangeable parts, lightweight, and heavy load capacity.

It is still another object of the present invention to provide a collapsible shipping container comprising a base frame and a roof frame having limited vertically extending peripheral walls, respectively, defining a vertical base channel and a vertical roof channel, respectively, for engaging therein the tops and bottoms of abutting panels and corner posts. Locking means are provided for engaging the corner posts to the base, the corner posts to the panels, and the corner posts to the roof frame, respectively. When the container is detached the peripheral walls of the base and roof frame, respectively, complementarily engage each other, defining a substantially reduced container cavity therebetween in which the panels and corner posts may be disposed for return shipment or storage. A decking panel of matrix construction may be advantageously secured to the base frame for supporting heavy loads, and the unit is adapted for aluminum extrusion manufacture and provides rigid construction and assembly and interchangeable parts.

With these and other objects in view which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:

Referring now to the drawings, and in particular to FIG. 1 through 14, the shipping container, designed in accordance with the present invention, comprises a base frame 1 supporting .a decking panel 2, preferably welded thereto, which in turn supports four corner posts 3, releasably connected to the decking panel 2. The base frame 1 is formed of side and rear members 1b (hereinafter both being referred to as side members since they are identical in construction except as to size) and which include horizontally extending vertical channels 4 for supporting therein side and rear panels 5 (hereinafter both being referred to as taken along the lines side panels since they are identical) which together with the corner posts 3 support thereon is releasable engagement a roof panel 6. A locking assembly 7 is provided for releasably locking the corner posts 3 to the decking panel 2; a locking assembly 8 is provided for connecting releasably the side panels 5 to the adjacent corner posts 3; and a locking assembly 9 is provided for connecting the roof panel 6 to the corner posts 3. A door panel 10 containing external locking assembly 11 completes the unit and releasably connects to adjoining corner posts 3. The locked and assembled shipping container is shown in FIG. 2. All lock assemblies, except for the door panel lock assembly 11, are provided inside the shipping container thereby minimizing exposure of locks.

The side panels 5 are received in the vertical channels 4 which may be integral with the side member 11), as shown in the drawings, or which may comprise pins or a wall disposed on the decking panel (not shown), or the like.

The base frame 1 is preferably formed of aluminum extrusions constituting three substantially identical members 1b, as shown in FIGS. 5, 11 and 12. Each member is extruded with a support ledge 1a which is cut at mitered or corner ends 1c and welded thereat together (FIG. 5 The side members lb are also extruded with vertical outer peripheral walls 4a terminating in terminal ends 13 at the corner ends 1c of the members 1b and thereat Welded to adjacent terminal ends 13. The side members 1b also include vertical inner peripheral walls 4b spaced from the outer peripheral walls 411, which walls 4b vertically terminate at an upper edge 23 which is lower than the upper edge 22 of the outer peripheral walls 4a. A horizontal floor 40 extends from the lower end of the inner peripheral wall 4b and connects to the outer peripheral wall 4a, therewith forming the channel 4, for supporting therein the side panels 5.

The support ledge 1a is extruded integral to and extends inwardly from the bottom of the outer peripheral wall 4a,

terminating somewhat further inward than the inner peripheral wall 4b of the vertical channel 4, and is spaced below the floor 4c of the vertical channel 4, forming therebetween chanel 12 about the inner periphery of the base frame 1.

As shown in FIGS. 3 and 4 the decking panel 2 is complementary to and disposed in the channel 12 on the support ledge 1a and snugly abuts the bottom of the floor 40. With this channel construction, maximum carrying capacity is achieved in cooperation with the decking panel 2 which is preferably formed of hollow fortifications constituting a matrix formation 2a which is welded to the outer edges of the support ledge 1a and the floor 40, respectively. The decking panel 2 may also advantageously be used in upside-down position (not shown) as the matrix is closely spaced and provides excellent support in both positions in the channel 12.

Legs 14 depend vertically downwardly from the lowermost end of the outer wall 4a and include horizontal leg portions 14a at the bottom. As shown in FIG. 11 the legs 14 have inclined edges 14b forming an angle of about 30 with the vertical, for strength, and are formed at each corner of the unit, and centrally intermediate the corners, to provide sufficient support for the unit.

Referring now again to the drawings, and more particularly to FIG. 5, the vertical channel 4, constituting the outer peripheral wall 4a, inner peripheral wall 4b and floor 4c therebetween, is open at the top and at lateral ends 4d thereof; and the inner peripheral wall 4b and the floor 4c terminate laterally thereat adjacent to but spaced from the corner ends 1c of the side members 1b of the base frame 1. In this manner a corner space is provided between adjacent lateral ends 4d of the channels 4 of the members 1b in which the corner posts 3 are abuttingly inserted as may be seen in FIG. 1 illustrating three corner posts 3, inserted between adjacent lateral ends 4:! of the channels 4 and one corner post 3 ready for insertion.

The corner posts 3 are formed with two vertically elongated walls 3a perpendicular to each other and complementary to the joined terminal ends 13, respectively, of the outer peripheral walls 4a of the members 1b at the corner ends of the members, in which corners they are disposed and supported on the decking panel 2. The outer edges of the walls 3a of the corner posts 3 are formed with perpendicular flange members 3b of a width substantially equal to the width of the vertical channel 4, and which abut complementarily the lateral ends 4d of the vertical channels 4, as shown in FIGS. 1, 3, 4, 6, 7 and 17.

The side panels 5 have a transverse length equal to the length of the channels 4 and the flange members 3b abut the lateral side members 5c of the side panels 5 when the side panels are inserted into the vertical channels 4. The corner posts 3, supported on the decking panel 2, are secured thereto by a locking assembly mounted on the corner posts 3, as will hereinafter be described in further detail. Locking assembly 8, also mounted on the corner posts 3, secures the side panels 5 to the adjoining flange members 3b of the corner posts 3.

Referring now again to the drawings, and more particularly to FIGS. 5, 9 and 10, the base frame 1 also includes a front member 1d which is similar to side members 1b but does not include the vertical channels 4 of the side members 1b. Also, the outer peripheral wall 4a of the front member 1d is recessed centrally to form a horizontal edge 4a at a level corresponding to the top surface of the decking panel 2. The outer peripheral wall 4a of the front member 1d has terminal ends 13 of the same height as the terminal ends 13 of the adjoining side members 1b to which it is welded for abutting corner posts 3 therein. As shown in FIG. 1, the width of the outer peripheral wall 4a of the front member 1a, adjacent the terminal ends 13, is approximately equal to the width of the walls 3a of the adjoining corner posts 3 which are disposed in the corners between the front member 1a and the adjoining side members 1b of the base frame 1. The front member la! is also formed with the support ledge 1a, the same as that of the side members 112, and includes mitered or corner ends 1c welded to the adjoining mitered ends 10 of the side members 1b.

The side panels 5 are preferably formed with a filler structure 5a, or the like (FIG. 2), and are covered at the top and bottom with aluminum strips See, at the inner face with aluminum sheet 5b, and at the lateral sides thereof with L-shaped side members 56, which are welded to the filler structure 5a, respectively. When inserted into the vertical channels 4, the side panels 5 extend vertically and substantially beyond the top edge 22 of the outer peripheral walls 4a of the base frame 1 and the L- shaped members So at the lateral sides of the side panels 5 are contiguous to the flange members 3b of the adjacent corner posts 3 and extend vertically therealong, both the corner posts 3 and the side panels 5 terminating at the top at substantially the same height.

Referring now again to the drawings, and more particularly to FIGS. 3, 4 and 6, the roof frame 6 is formed with a downwardly facing vertical channel 16 complementary to and engaging the top portions of the side panels 5 and the corner posts 3. Between the channel 16 of the roof frame 6 and the vertical channel 4 of the base frame 1, substantial portions of the side panels 5 are exposed as shown in FIG. 2.

Referring new again to the drawings, and more particularly to FIG. 6, the .roof frame 6 is formed preferably by aluminum extrusion and includes four substantially identical roof members 17, each having a horizontal top wall 170 which is mitered at the ends thereof and welded together. Cross-members 18 are welded to opposite roof members 17 of the roof frame 6 to provide additional strength and support, and aluminum sheet 19 is provided to cover the roof panel (not shown in FIG. 6).

Reference now again to the drawings, and in particular to FIGS. 3, 4, 6 and 20, the channel 16 for the roof frame 6 extends to the mitered ends of the roof members '17 and comprises a vertical inner peripheral wall 16a and a vertical outer peripheral wall 16b between which at the upper ends thereof is connected the horizontal top wall 17a. The outer peripheral Wall 16b includes an upper portion 160 spaced from the inner wall 16a by the thickness of the side panels 5, as shown in FIG. 3, for complementally engaging therebetween the top portions of the corner posts 3 and the top portions of the side panels 5. The outer peripheral Wall 16b includes an outwardly oriented L-shaped flanged portion 16d having having a horizontal portion 16e and a vertical portion 16], the latter being spaced from the upper portion 160 by a distance approximately equal to the thickness of the outer peripheral wall 4a of the base frame 1. In this manner, as may readily be seen in FIG. 15, when the corner posts 3 and the side panels 5 are detached and removed for collapsing the container, the vertical portion 16 of the flanged portion 16d of the channel 16 of the roof frame 6, overlappingly engages the outer peripheral Wall 4a of the base frame 1, and the upper edge 22 of the outer peripheral wall 4a rests on the horizontal portion 16e of the flange portion 16d of the outer peripheral wall 16b of the roof frame 6. Lower edge 16g of the inner peripheral wall 16a of the channel 16 of the roof frame 6 is lower than the horizontal portion 16e of the outer peripheral wall 16b, and complementary to the upper edge 23 of the inner peripheral wall 4b of channel 4 of the base frame 1, which edge 23 extends below the upper edge 22 of the outer peripheral wall 4a of the base frame 1, to insure good complementary mating engagement of the corresponding inner and outer peripheral walls 4b and 16a, and 4a and 16b, respectively, of the base frame 1 and the roof frame 6 in the collapsed position.

The lengths of the inner and outer peripheral walls, respectively, of the roof frame 1 and the base frame 6 are selected to provide a predetermined volume capacity to permit the reception therein between the base frame 1 and the cooperating abutting roof frame 6, of the other structural members of the shipping container when not in use. This requires a certain ratio between the height of the side panels and the available horizontal space on the decking panel to permit the side and door panels to be contained in the collapsed container. As shown in FIG. 15, the three side panels 5 (including the rear panel which herein is somewhat smaller in size than that of the other side panels due to the rectangular configuration of the unit), and the door panel (which is equal in size to that of the rear panel) are horizontally inserted in compact arrangement into the predetermined space between the roof panel 6 and the base frame 1 along with the four corner posts 3.

When the decking panel 2, corner posts 3, side panels 5 and roof frame 1 are in assembled position and locked together, as hereinafter described in further detail, the door panel 10 (preferably structurally similar to the side panels 5, including filler 10a and L-shaped lateral side members 100) is inserted into the front of the shipping container for completing the assembled unit. The top portion of the door panel 10 is slided above the recess 4a of the outer peripheral wall 4a of the front member 1d into the channel 16 of the roof -6. The door panel 10 has a forward lip extension 1011' which overlappingly engages the recessed edge 4a of the outer peripheral wall 4a of the front member 1d of the base frame 1, for locating the door panel 10 in position. The sides 5c of the door panel 10 abut the adjoining flange members 3b of the forwardmost and adjoining corner posts 3 and are locked thereto as will be described.

Referring now again to the drawings, and more particularly to FIGS. 1, 13, 17 and 18, the locking assembly 7 for locking the corner posts 3 to the decking panel 2 is disclosed. A base plate is welded to the lower end of the corner posts 3 and has an opening 3d therein. A bolt 7a, joined to the decking panel 2 at the corners thereof, extends upwardly from the bottom of the decking panel 2 through a nut 7b and washer 7c combination, which is welded together and to the bottom of the decking panel 2, and extends through the decking panel 2, being welded thereto, and projects upwardly therefrom, terminating through an upper washer 7d and nuts 7e welded to the washer 7d, the latter washer and nuts being spaced from the top surface of the decking panel 2. The opening 3d is sufficiently large to permit the base plate 3c of the corner post 3 to fit over the washer 7d and nuts 7e when the corner posts 3 are positioned in the corner ends of the base frame 1 for resting on the decking panel 2, as indicated in FIG. 18.

Mounted on the upper face of the base plate 30 of the corner post 3 is a lever arm 7 f pivotally mounted at one end to the base place 30 by pivot pin 7g. The other end of the lever arm 7f has mounted thereon a spring biased pick-up handle 7h with snap-in pin 7i extending through the bottom of the lever arm 7 f. The lever arm 7 f is adapted to be pivoted into locking position into the path of the opening 3d, in the base plate 30, and the bolt 7a, extending therethrough, above the base plate 30 from the decking panel 2. The lever arm 7 has a complementary recess 7 which engages the bolt 7a in the locking position (as shown in FIG. 18; and the front locking assembly 7 of FIG. 17, the rear locking assembly of FIG. 17 being shown in the unlatched position). As indicated in FIG. 18 the bottom of the washer 7d is spaced from the upper face of the base plate 3c by a distance equal to the width of the lever arm 7], so that in the locked position the lever arm 71 snugly abuts both the bottom of the washer 7d and the upper face of the base plate 30 to secure the corner posts 3 to the decking panel 2 in rigid locking position. A pin opening 8k is provided in the base plate 3c of the corner post 3 for receiving therein the snap-in pin 7i of the handle 7h of the lever arm 7 when the lever arm 7 is in locking position engaging the bolt 7a with the recess 7 thereby securing the locking assembly 7 tightly in position. One locking assembly 7 is provided for each corner post 3 on the base plate 3c thereof for locking the respective corner posts 3 to the corners of the decking frame 2. Secure engagement is achieved with relatively simple means because of the cooperative engagement of the complementary side walls 3a and the flange members 3b of the corner posts 3 against the terminal ends 13 of the outer peripheral walls 4a and the lateral ends 4d of the channel 4 of the base frame 1, respectively.

Referring now again to the drawings, and in particular to FIGS. 1, 17, and 19, the locking assembly 8 for locking the corner post 3 to the side panels 5 is disclosed. The locking assembly 8 comprises a lever arm 8a pivotally mounted intermediate the ends by a fixed pivot pin 8b to the side walls 3a of the corner posts 3 adjacent the flange member 3b. One end of the lever arm 8a contains a handle for moving the lever arm 8a and includes spring-biased snap-in pin 8d extending through the lever arm 8a. The other end of the lever arm 8a contains a movable pivot pin 8e to which is pivotally mounted a second lever arm 8f, the fixed pivot pin 8b being adjacent the movable pivot pin 82. The free end 8g of the lever arm 8f includes an L-shaped engaging surface 8h; a bolt 8i extends therethro-ugh to the engaging surface 8h. As indicated in FIGS. 17 and 19, illustrating the locking assembly 8 in locked position, the engaging surface 8b of the lever arm 8 engages the L-shaped side member 5c of the side panel 5 from the interior thereof. For this purpose, aligned windows or cut-out portions 5d and 3d, respectively, are formed in the L-shaped member 5c of the side panel 5, and in the flange member 3b of the corner post 3, respectively, to permit the lever arm 8 to pass therethrough. In the locked position the engaging surface 8h also abuts the lower edge of the aligned cut-out portions 5d and 3d defining a complementary L-shaped engagement of the side panel 5 by the engaging surface 8h. The lever arm 8a is formed with a convex cam portion 8 which engages the opposite side of the flange member 3b of the corner post 3, directly opposite the engaging surface 8h of the lever arm 8f, thereby jointly engaging the side panel 5 and the corner post 3 between the cam portion 8 and the engaging surface 8h in sandwich abutment. In this locked position the snap-in pin 8d of the handle 8c is received into a pin hole 8k for locking the locking assembly 8 in position. As shown in FIG. 19 there are two locking assemblies 8 for each side of each side panel 5 and each half of each corner post 3. The bolt Si is provided to insure good engagement surface contact and two locking nuts 81 are provided for adjusting the surface engagement to account for tolerance differences between the parts, to relieve pressure on the pivot pin 8d and to adjust for wear on the bearing. With this construction the lever arm 8 is urged securely and in excellent clamping position against the L-shaped side member c of the side panel 5 by rotation of the movable pivot pin 82 'tensionally away from the side panel 5 and simultaneous rotation of the cam portion 8 against the flange member 3b of the corner post 3.

To unlock the locking assembly 8, for removing and disassembling, the shipping container, the handle 80 is pulled, thereby lifting the snap-in pin 8d out of the hole 8k, and the lever arm 8a is pivoted (to the left as shown in FIG. 19 in dashed lines), thereby causing the lever arm 8a to pivot about the fixed pivot pin 8!) and causing the movable pivot pin 82 to rotate toward the side panel 5 thereby relieving the clamping pressure against the engaging surface 8/1 of the lever arm 8 and removing the cam portion 8j away from the clamping position against the flange member 3b of the corner post 3. In this position the lever arm 8f may be easily lifted and rotated counter-clockwise, out of the cut-out portions 5d and 3d, thereby detaching the side panel 5 from the corner post 3.

An upper and lower locking assembly 8, as just described, are provided on each flange member 3b which abuts the side panels 5 (the upper assembly 8 being illustrated in FIG. 19).

The door locking assemblies 11 are identical to the side panel locking assemblies 8 with the exception that the door locking assemblies 11 are pivotally mounted to the door panel 10 instead of to the flange members 3b of the corner posts 3 so as to be accessible from the outside. Like parts of the door locking assembly 11 shown in FIG. 17 are designated by the same alphabetic subscripts as the corresponding parts of the side panel locking assemblies 8 but are preceded by the numeral 11. The handle 11c, lever arm 11a and lever arm 11 of the door locking assembly 11 are disposed in a front recess 11' (FIGS. 1 and 2) in the outside of the door panel 10. The engaging surface 1111 of lever arm 11], in the locking position passes through the L-shaped side member 100 through window 10a therein and through flange member 3b via cut-out portion 3d therein and presses against the inside of the flange member 3b. The cam portion 11j of lever arm 11a oppositely presses against the L-shaped side member 100 of the door panel 10.

Referring now to the drawings, and in particular to FIGS. 1, 6, 19 and 20, the roof locking assembly 9 is shown, comprising a contoured lever arm 9a pivotally connected at one end by pivot pin 9b to the inner side of the inner peripheral wall 16a of the roof frame 6. Locking pins 9c are welded to the upper part of the flanged members 3b of the corner posts 3 and extend horizontally therefrom through a vertical contoured slot 9d formed in the inner peripheral wall 16a of the roof frame 6 and which slot 9d fits upon the locking pins 90, when the roof frame 6 is positioned on the tops of the side panels 5 and the corner posts 3. The slot 9d is of such a length that the locking pin 90 abuts the upper end of the slot 9d when the horizontal wall 170 of the roof frame 6 is contiguous to the top of the side panels 5. The lever arm 9a is adapted to be pivoted about pivot pin 9b toward the locking pin 90, by a handle 9e at the remote end of the lever arm 9a for moving the lever arm 9a into locking position against the pin 90. The lever arm 9a is formed with a contoured recess 9 complementary to the locking pin 90 for this purpose for engaging the pin 9c. A spring, snap lock 9g is provided adjacent the recess 91 and which resiliently passes over the pin 90 during locking and snaps over the pin 9c as shown in dashed lines (FIG. 20) for securing the lever arm 9a in the locked position, as illustrated by the righthand locking assembly 9 of FIG. 20. One looking assembly 9 is provided for each flange member 3b of the corner posts 3 as indicated in FIGS. 19 and 20.

Referring now again to the drawings, and more particularly to FIG. 8, lifting lugs 20 comprising an angle member with holes 21 therein, are welded to the corners of the roof frame 6 along the horizontal portion 16e for lifting the assembled and locked unit if necessary, such as for example into the hold of a ship.

In the assembled condition, the shipping container has a predetermined volume capacity to receive products to be shipped. With the present invention the strength is very high relative the volume so that extremely heavy loads and large volume capacity can be utilized. The unit may be constructed large enough for a person to go within the unit when the front door is removed and the roof frame is positioned, to lock the roof frame to the corner posts. The other locking assemblies may be readily secured prior positioning of the roof frame if desired. Loading is readily accomplished before or after positioning of the roof frame, depending on the requirements of the loading.

As an example of a particular useful design in accordance with the present invention, although not limited thereto, the container completely of aluminum construction measures 6 feet 10 inches high by about 6 feet 8 inches wide, and 8 feet long, and holds approximately 330 cubic feet of cargo, and with the particular decking panel structure can hold approximately 6 thousand pounds of uniform load. When the container is collapsed, it will be preferably 1 foot two inches high, 6 feet 8 inches wide, and 8 feet long, and when interlocked and stacked, for example, as in FIG. 16, comprising four stacked collapsed containers, four containers will have a total height of 4 feet 6 inches, the locking lugs 20 adapted for complementary engagement about the corner legs 14 of the next upper stacked container. The weight of the empty shipping container is approximately 600 pounds.

Such a volume and load capacity provides a very high weight to volume strength, permitting such a container structure to be built in larger sizes and for use with heavier loads than heretofore achieved. The unit is readily manufactured by a complete extrusion process for the base frame and the roof frame.

All parts are replaceable and interchangeable and repair work is kept to a minimum.

The shipping container maybe readily adapted for use as a refrigerator container by providing the necessary seals and using a refrigerator decking.

The unique construction and secure locking means provides a new and improved concept in collapsible shipping containers. Rapid assembly and easy movement are achieved and the unit is sturdy in the locked condition and can tolerate variable conditions of shipping, and other advantages.
