It will be understood that the above drawings illustrate merely a preferred embodiment of the invention, and that other embodiments are contemplated within the scope of the claims hereafter set forth.

Referring to the drawings the present convertible shipping box is designated at 11, FIG. 1 and includes bottom panel 12, top panel 13, ends 14, and side panels 15 and 16.

In the converted box a series of bottom panels are reassembled in coplanar relation to define floor section 17 of FIG. 3.

A series of top panels 12 are reassembled in coplanar relation to define the roof section 18 of FIG. 3. A series of side panels 15l6 are reassembled into a series of coplanar assemblies to define a plurality of right angularly related groups of panels and thus defining the wall sections generally indicated at 19, FIG. 3 for the building structure.

Within the assembled box, FIG. 1 there is provided a waterproof liner sheet 20 of a suitable kraft paper or fibre reinforced paper sometimes referred to as sisal kraft or other suitable moisture proof material. In the converted building structure the liners from a plurality of the said disassembled boxes may be employed as a threeply roof covering as designated fragmentarily at 23, FIG. 3 in the completed roof assembly.

Bottom panel Referring to FIG. 5 bottom panel 12 includes a supporting framework consisting of a series of joists 21 of an illustrative dimension 2" x 6 and with right angularly related cross bridging 22 of the same dimension, and fixedly secured thereover the inner wall 23 which in the illustrative embodiment is formed of plywood one half inch thick, for illustration. An outer wall 24 is also arranged over the same framework and consists of plywood, for illustration, of one quarter inch thickness, the said inner and outer walls being suitably secured to the framework as by gluing and by fasteners forming a unit bottom panel which is essentially hollow for insulating purposes and for strength of construction.

As shown in FIGS. 2 and 5 said bottom panel includes a peripheral cutaway ledge 26 which is defined by outer framing 26 which extends around and is secured to bottom panel frame 21-22, being of a dimension 2 x 4", for illustration.

A series of longitudinally spaced outwardly opening apertures are formed through the bottom panel frame elements 21 and 22 adjacent the ledge 2-6 and there are secured within each of the said apertures a metallic nut such as a T nut 27 which remains in position at all times and which is adapted to cooperatively receive suitable fasteners such as the lag bolts 31, MG. 5 which extend through correspondingly spaced apertures within the adjacent side panels and ends of the box construction.

Side panels The respective side panels 15 and 16, said numerals being used interchangeably in FIG. 3, include a hollow frame 23 which in the illustrative embodiment has a dimension of A" X 3" with outer wall 29 of at" plywood, for illustration, and inner wall 39 of A. plywood, for illustration, also suitably glued and otherwise fastened to the said frame 28.

Each of the side panels have formed therethrough the correspondingly referred to apertures which register with the said nuts 27 and which removably receive the fasteners or lag bolts 31, FIGS. 1 and 5.

Top panel The top panel 13 consists of a hollow framework which includes corresponding joists 21, preferably 2" x 6" and the intersecting cross bridging 22 of corresponding dimensions. Surrounding frame 2122 there is provided an additional outer frame 33 in cross section 2 x 4", for illustration, to thus define within the undersurface of the top panel 13 a peripheral ledge 26 corresponding to the peripheral ledge 26 of the bottom panel. Outer Wall 24 of 3 3" plywood, for illustration; and inner wall 23 of A" plywood, for illustration, are glued upon opposite sides of frame 21-22 and otherwise secured thereto. As particularly noted in FIG. 2 the elements which make up the top panel include portions of gradually increasing height towards one end thereof to define a small pitch angle 34, which is approximately 2" over the length of said top panel, which in the illustrative embodiment is 8 feet long. This pitch is useful when the top panels of a series of disassembled boxes are reassembled as shown in FIG. 3 to define the roof section 18 for the converted building structure to give it a slight pitch angle.

Box ends The detail of the box ends 14 are best illustrated in FIGS. 6, 7, and 8, and include the hollow frame 35 with cross frame elements 36 and secured upon its opposite sides respectively inner wall 37 which is of /4" plywood, for illustration, outer wall 38 which is of /4 plywood, for illustration. As shown in FIG. 7 at least one pair of the outer edges of each end 14 are laterally flanged at 3? to define ledges or adjacent cutaway portions 4!) which in the assembled box, FIG. 2 permit the said ends and the said cutaway portions to be projected between the respective panels throughout 360.

Corresponding apertures are formed through adjacent edge portions of the ends 14 and through the said flanges as at 41 and are adapted to receive additional fasteners such as the lag bolts 31 or screws by which the said ends in the completed box construction may be secured to the respective box panels.

As shown in FIG. 1 there are provided upon the undersurface of bottom panel 12 a series of elongated laterally spaced skids 42, of rectangular cross-section. In the disassembled box these skids are removable and are shown in FIG. 3 as providing securing fillers nested within the slots defined between adjacent ledges of the assembled bottom panels which define the floor section 12 and also provide one means by which the adjacent floor panels may be secured together in coplanar edge to edge relation and to thus provide a fiat floor assembly.

When the boxes have been disassembled and have been reassembled to form the respective floor section 17, roof section 18 and wall section 19, the preassembled floor section is mounted over a series of longitudinally spaced parallel foundation beams 43, FIG. 3 which includes sup porting piers 44 nested down into the ground surface and which are prepared locally for supporting the converted building construction as shown in FIGS. and 11.

In the completed building a suitable elongated support beam 45 is interposed and secured between an opposing pair of building side wall rections 19 to supportably span the adjacent inner registering ends of the assembled coplanar top panels 13 which form the roof section 18.

Window construction FIG. 9 is a fragmentary illustration of one of the side panels 16 which incorporates an initially protected window assembly when used in the box construction, such as shown in FIG. 2. The window assembly 46, FIGS. 2, 3 and 9 includes rectangular window frame 43 nested and secured within and between the inner and outer walls 30 and 29 of side panel 16, for illustration, and including the formed sill 49. Assembled therein is window 50 which is pivotally mounted at its upper end within said frame and which is adapted to swing outwardly as shown in dotted lines, FIG. 9. Adjacent portions of the inner wall 30 and outer wall 29 relative to said window are cutaway and removable cover elements or panels 51 and 52 are secured therein coplanar with the inner and outer walls which form the side panel and which in normal use of the construction as a box protect the Window assembly against breakage.

Outer cover panel 52 is secured by fasteners 53 to the window assembly 50 and upon opening of the window may remain thereon or can be removed as desired. The inner cover panel 51. secured as at 53 to an inner portion of the window assembly 50, in a coplanar registry within the cutaway portion of the inner wall 30 of the side panel but a lower portion at least of the panel element 51 overlaps window frame 49 to normally retain the complete window assembly against opening until the said panel 51 has been removed by removal of fasteners 53. Under some conditions the window may not be used in the reassembled building structure and accordingly the panels 51 and 52 will remain secured in place.

Within one or some of the side panels, as for example, side panel 15, FIG. 2 and FIG. 3, there is also provided a rectangular door frame as an integral part of said panel similar to but of different dimensions than window frame 48, FIG. 9. Removably nested within said door frame is door 47 which is hinged along one of its edges as at 54 which may be used in the assembled building as the door to the building, FIGS. 3, and 10. If not so used, said door is covered by removable panels similar to removable panels 51 and 52 of FIG. 9.

With reference to FIG. 4 there is shown in a diagram and schematically a series of boxes as, for example one group showing. six boxes stacked together which when disassembled may be reassembled to provide a building having the door plan such as shown adjacent thereto. In other words six reassembled boxes will provide a build ing which has the front and side dimensions of eight feet by sixteen. Seven boxes will provide a floor plan twelve by sixteen; eight boxes a floor plan sixteen by sixteen; twelve boxes a floor plan sixteen by twenty-four; twentyfour boxes a floor plan forty-eight by sixteen. This illushates the means by which the modular box construction can be on this assembly reassembled into useful building structures. The eight boxes shown in FIG. 4 and the floor plan adjacent thereto corresponds to the building shown in FIG. 3.

Thus by the present invention wherein old, shipping boxes and containers are destroyed his seen wherein the present invention that the present convertible box may be reused for the assembly of a building which requires no additional materials other than what is shown in the building construction and which can be assembled with the minimum of effort and requiring only a screwdriver, hammer and Wrench. Thus, the same containers which provide enclosures for machines or other equipment shipped have incorporated thereinto the pre-assembled materials for the fabrication of buildings, being merely a reuse of the respective parts of the shipping box.

For emergency disaster areas, food, clothing, and medical supplies, shipped in the present box arrive simultaneously with the shelter buildings into which said boxes are converted.

In the conversion, the said end panels 14 of the shipping boxes may be used as partitions in the assembled building, if desired. The present invention contemplates also the reconversion of the building back to shipping boxes as desired.
