     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved adjustable door assembly embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the adjustable door assembly 10 includes a rigid door 11, having a first side wall 12 spaced from a second side wall 13, with a first end wall 14 spaced from a second end wall 15, wherein typically the first and second end walls 14 and 15 respectively are orthogonally oriented relative to the first and second side walls 12 and 13. The first and second end walls 14 and 15 include respective first and second end wall cap members 16 and 17 slidably received over the rigid door about the first and second end walls 12 and 13. The caps are of identical construction, wherein description of the first end wall cap 16 is to be understood as applicable to the second end wall cap 17. 
     The first end wall cap 16 includes cap first and second end walls 18 and 19 arranged for reception of the respective first and second side walls 12 and 13 of the door 11. A cap floor plate 20 is arranged to include a floor plate canted interior surface 21 arranged to extend from the cap first end wall 18 to the cap second end wall 19 of a first thickness adjacent the first end wall 18 to a second thickness adjacent the second end wall 19, wherein the first thickness is greater than the second thickness. The canted door structure permits pivoting of the cap first end wall 18 relative to the door first side wall 12 projecting the cap second end wall 19 over the door second side wall 13. It is to be understood that the clearances of the cap relative to the door 11 permit the pivoting relationship as indicated. The apparatus includes a hinge web 22 having hinged plate members, including a first plate member mounted to the canted interior surface 21 adjacent the cap first end wall 18, with a second plate member mounted to a hinge rod 23, that in turn is orthogonally and slidably received through the door first end wall 14 in adjacency to the door first side wall 12. A rod cavity 24 slidably receives a rod 23 therethrough, with the rod 23 having an abutment plate 25 fixedly mounted to the rod within the cavity 24. The cavity 24 includes a cavity roof 26 spaced from a cavity floor 27, with a spring member 28 interposed between the abutment plate 25 and the cavity floor 27. In this manner, hinged orientation of the cap 16 is availed relative to the door first end wall 14. Further, a cavity bearing strip 29 positioned within the cylindrical side wall of the cavity 24 is arranged for cooperation with an abutment plate bearing strip 30. The strips 29 and 30 are typically formed of TEFLON or any suitable sliding bearing substance. 
     An internally threaded bore 31 is directed into the first end wall 14, as well as into the second end wall 15, each to receive an externally threaded adjustment rod 32, having an adjustment rod head 33 rotatably mounted within the floor plate 20 and the interior surface 21. In this manner, threaded projection of the adjustment rod 32 into the internally threaded bore 31 directs either the first or second end wall cap 16 or 17 into the respective first and second end wall 14 and 15 about an associated bifurcated hinge web 22. 
     FIGS. 5 and 6 indicate the lock plate structure 34 optionally employed by the invention arranged for slidable adjustment longitudinally of the door second side wall 13. The lock plate 34 includes an end wall 35 in contiguous sliding communication with the door second side wall 13, with the lock plate end wall 35 having a plurality of longitudinally aligned slots 36, each including an end wall fastener 37 orthogonally directed through the end wall through an associated slot 36, with each end wall fastener 37 received within an end wall fastener cavity 38 within the door structure in adjacency to the second side wall 13 of the door 11. The fastener cavities 38 are substanstially coextensive relative to the slots 36, with a fastener cavity lock plate 39 slidably mounted within each fastener cavity 38 threadedly receiving an associated fastener 37 therewithin. In this manner, loosening of the fasteners 37 permits sliding of the lock plate structure 34 relative to the door 11. 
     The FIGS. 7 and 8 indicates the use of a compressible polymeric foam core 41 functioning as an insulative and spring material directed coextensively between the door end walls 14 and 15 relative to the associated interior surfaces 21. A plurality of resilient polymeric columns 42 are orthogonally mounted between the door end walls 14 and 15 and the associated interior surfaces and are arranged to include a rigid stress plate 45 mounted coextensively to the canted interior surface 21 to distribute force from the resilient polymeric columns 42 evenly relative to each respective cap. Each of the columns 42 is indicated to include a column first end 43 rotatably and pivotally mounted within a first end cavity 44 within the stress plate 45. The columns second ends are arranged for contiguous communication and mounting to the associated door end walls. In this manner, biasing of the caps are provided, as well as functioning as an insulative barrier relative to each of the cap structures 16 and 17. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
