     FIELD OF INVENTION 
     The present invention relates generally to the field of structures and more particularly to easily disassembled, interlocking structures. 
     BACKGROUND OF THE INVENTION 
     The great majority of structures, containers and furniture are interlocked from component parts that are permanently affixed to each other. It was thought that permanent assembly resulted in greater strength and rigidity than containers or furniture capable of disassembly. Generally, manufacturing costs of permanently assembled structures, containers and furniture are less than structures, containers or furniture capable of disassembly. Often, these permanently interlocked structures, containers and furniture are designed for easy assembly by unskilled, inexpensive labor. It is well known in the art to use attachments such as glue, nails, screws, angled metal braces, and the like to permanently affix structures, containers and furniture together. 
     The permanently assembled structures, containers and furniture are shipped in their assembled to state directly to retailers. These assembled articles takes up a great deal of volume resulting in higher shipping costs. In a collapsed or flattened state, the structures, containers or furniture take up much less volume significantly reducing shipping costs. There are some drawbacks to the collapsible structures, container or furniture such as inferior quality, strength and durability. Another drawback is that the end user assumes the burden of assembly. This usually requires the assembler to possess the necessary tools and the wherewithal to use them to properly assemble the structure. 
     The prior art lacks a container or furniture shipped in a low volume disassembled state that the eventual user can easily assemble into a sturdy and structure without tools or special skills. The present invention satisfies these requirements, as well as others. 
     BRIEF SUMMARY OF THE INVENTION 
     The invention resides in an interlocking structure. It can be shipped in a low volume disassembled state. It is easily interlocked together, without tools or special skills, by the eventual user. The interlocked structure has uncommon rigidity and strength. Containers like dresser drawers, laundry baskets or waste paper baskets, shelters like dog houses and human shelters, or furniture like a portable fireplace can be interlocked together using a plurality of interconnecting rods and hooks 
     The easily assembled interlocking structure includes at least one rod. The rod has a U-shape with a first end and a second end. The interlocking structure has at least four sides and a bottom. The four sides include a right side, a left side, a front side and a back-side. Each side has four edges. The bottom also has four edges. To connect the four sides together, removeably interlock the edge of each side to the edge of the adjacent side. The bottom side removeably interlocks to at least two of the interlocked sides.

A pair of hooked-rod, receiving tubes  302  are horizontally located on the upper edge  202  of the back-side  162 . The hooked-rods  298  are slideably connected into the hooked-rod-receiving tubes  302 . 
     In yet another variant of this invention, the right side  214 , the left side  242 , the front side  114 , the back-side  162  and the bottom  270  are fabricated from metal wire, whicker stretched over a metal wire frame, plastic, wood with plastic cantilevered rods or wood with metal cantilevered rods. 
     Another variant of this invention, shown in FIGS. 10 through 13, is used to construct a portable fireplace  410 . The four sides are interlocked together by a first frame  414  and a second frame  418 . The four include a first side  422 , a second side  426 , a third side  430  and a fourth side  434 . Each side has a first substantially vertical edge  442  and a second substantially vertical edge  442 . The size and shape of the first frame  414  and the second frame  418  facilitates its removeable interlocking with each adjacent side and removeable interlocking to the bottom  446 . 
     The first frame  414  has a first substantially vertical support  454  linked by at least one cross member to a second substantially vertical support  458 . The second frame  418  has a first substantially vertical support  462  linked by at least one cross member  466  to a second substantially vertical support  470 . Each substantially vertical support  454 ,  458 ,  462  and  470  has a first end  474 , a second end  478 , a front face  482 , a back face  486  and an inner face  490 . 
     The bottom  446  includes a plate  494  removeably interlocked to a base  498 . The plate  494  serves as an ash and flame shield. The first frame  414  and the second frame  418  are removeably interlocked into the plate  494 . The base  498  has a plurality of legs  502 . 
     The second side  426  and the fourth side  434  each have a first  506  and a second horizontal, coplanar rod  510  cantilevered outward from each substantially vertical edge  438  and  442 . The first frame  414  and the second frame  418  have a pair of horizontal rod-receiving holes  514  on the back face  486  of each substantially vertical support  454  and  458 . Each horizontal rod-receiving hole  514  is substantially perpendicular to the plane of each frame  414  and  418 . The second side  426  is interlocked to the first substantially vertical support  454  and  462  of the first frame  414  and the second frame  418  so that each first  506  and second horizontal coplanar rod  510  is installed into the corresponding pair of horizontal rod-receiving holes  514  in each first substantially vertical support  454  and  462 . The fourth side  434  is interlocked to the second substantially vertical support  458  and  470  of the first frame  414  and the second frame  418  so that each first  506  and second horizontal coplanar rod  510  is installed into the corresponding pair of horizontal rod-receiving holes  514  in each second substantially vertical support  458  and  470 . 
     A grill  518  is placed upon the plate  494 . The first end  474  of each substantially vertical support  454 ,  458 ,  462  and  470  has a flap  522 . The plate  494  has four slots  526  sized, shaped and located to slideably receive the flap  522  of each substantially vertical support  454 ,  458 ,  462  and  470 . 
     The first side  422 , as shown in FIGS. 10,  11  and  13 , is releasably interlocking into the first frame  414  by a hinge means  530 . The hinge means  530  comprises a pair of outwardly cantilevered, hooked-rods  534  extending downwards from the first substantially vertical edge  438  of the first side  422  and a pair of hooked rod-receiving tubes  538  vertically located on the front face  482  of the first substantially vertical support  454  of the first frame  414 . 
     As shown in FIG. 12, the second frame  418  has a means for releasably interlocking with the third side  430 . Each substantially vertical support  454 ,  458 ,  462  and  470  has at least one pivoting locking plate  546 . The pivoting locking plate  546  pivots on a rotation point  550 . The third side  430  is retained when the first substantially vertical edge  438  is located against a cross member  450  and the second substantially vertical edge  438  is located against a cross member  450  and each locking plate  546  is pivoted into a horizontal position. 
     A fireplace lid, shown in FIG. 10, is installed by interlocking it with the second end  478  of each substantially vertical support  454 ,  458 ,  462  and  470 .
