     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 9 thereof, a new and improved door shield construction embodying the principles and concepts of the present invention and generally designated by the reference numerals 10, 10a, and 10b will be described. 
     More specifically, the door shield construction 10 of the instant invention essentially comprises a polymeric foam web 11, including an accordion fold layer 12 mounted coextensively to a forward surface of the web 11, wherein the layer 12 is defined by parallel rib members fixedly secured to the forward surface of the web 11. The web and layer 11 and 12 defined respective right and left edges 14 and 15, wherein the web 11 includes a continuous securement strip 13 mounted to the rear surface perimeter of the polymeric foam web 11. Adjacent the respective right and left edges 14 and 15 are respective right and left cylindrical perforations 16 and 17 to provide respective right and left knock-out portions to accommodate a door knob. Both knock-out portions are required as both right and left opening doors are available. Positioned below and adjacent each respective right and left cylindrical perforations 16 and 17 is a respective right and left bore 18 and 19. Each bore includes radial slots 18a and 19a respectively radially directed exteriorly of the respective bores 18 and 19 and each of the right and left slots are arranged orthogonally relative to one another to provide accommodation of a door knob therethrough in an alternative manner relative to the cylindrical perforations 15 and 16 to provide a more rapid mounting of the panel about a door knob. 
     FIGS. 4 and 5 illustrate the use of modified rib structure, wherein each of the ribs of the fold layer 12 includes rib cavities 20 to provide intermediate projections to more readily accommodate flexure of each of the ribs in the event of impact to the accordion fold layer 12. Further, the modified door construction 10a utilizes a magnetic strip 21 mounted coextensively adjacent an adhesive strip 22 to provide selective securement means of the continuous securement strip 13. In this manner, the magnetic strip permits immediate adherence to a ferromagnetic door surface, whereas the adhesive strip 22 accommodates non-ferromagnetic door members. 
     The further modified construction 10b as set forth in FIGS. 6 and 7 utilizes a writing pad 23 pivotally mounted to an upper terminal end of a mounting plate 24. A lower terminal end of the mounting plate includes an &#34;L&#34; shaped storage lip 25 for securement of writing instruments 26 thereon as further providing a ledge for mounting construction permits, construction directions, and the like. The writing pad 23 accommodates instruction by an owner or a foreman at the job site and the writing pad and associated mounting plate structure is positioned to the rear surface of the web 11 to afford protection and access to the writing pad 23 and &#34;L&#34; shaped storage lip 25, as well as affording protection thereto. An insert plate 27 is mounted to the rear surface of the web 11 below the mounting plate and utilizes adhesive numerals 28 for securement to the exterior surface of the accordion fold layer 12 to provide address enumeration of the door as covering of the door by the construction 10b will frequently provide such addressed numerals. In this manner, the adhesive address numbers 28 are removably mounted to a non-adhesive gloss surface 29 defined by the insert plate 27 removably mounting the adhesive address numbers thereon for the removal and subsequent adherence to the exterior surface of the accordion fold layer 12 providing address enumeration to ensure continuous delivery of mail, visitors, and the like at a construction site. 
     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.
