DETAILED DESCRIPTIQN OF AN EXEMPLARY EMBOL7ItVtElrlT
Referring now in detail to the accompanying drawing, there is illustrated an industrial door assembly according to the present invention, generally referred to by the numeral 10. As can best be seen ins Figures 1, 2A, and 2B, the exemplary embodiment of the industrial door assembly 10 comprises a rigid internal frame 12 having first and second sides 14, the rigid into>mal frame 12 being of steel tubing in this embodiment and welded together, and a o~oor capping 16 attached to edges 18 of the rigid internal frame 12, the dour capping 16 providing generally parallel faces 20 which are generally parallel to the first; and second sides 14. The rigid internal frame 92 comprises steel gussets 3n in every inside corner to strengthen the industrial door assernbfy 1C~ and help prevent prE~rnate.~re delamination.
The industrial door assembly 10 further comprises side panE.ls 22 which are attached to the generally parallel faces 20 of the door capping '16~ in an orientation generally parallel to the first and second sides 14 of the rigid internal frame 12. The hollow structure thus formed is filled, in the manner set Qut in the: following descriptior~, with a synthetic insulating material 24, specifically a urethane foam insulation in the 2b exemplary embodiment, which acts to bond the side panels 22 together and thus strengthens the industrial door assembly 9 Gl. Tile synthetic insulating material 24 is preferably an expanding foam that can expand after injection to fill the hollow structure.
The door capping 16 in the exemplary embodiment is a synthetic material extrusion, specifically a PVC extrusion. Referring to Figures 1 and 4, the door capping 16 comprises an elongate core body 32 from which extend two generally parallel flanges 34, the generally parallel filanges 34 being either attached to or formed as a unity witf~ the elongate core body 32, the generally parallel flanges 34 being oriented along the long axis of the elongate core body 32. The elongate core body 32 and the two generally parallel flanges 34 farm a receiving channel 36 for slideably receiving the edge 'I8 of the rigid internal frame 12, and the two generally parallel i9anges 34 provide the two generally parallel face; 20 fio which the side panels 22 are attached. The door capping '! fi further comprises receiving means 2B
for receiving any desired door hardware (not shown) or synthetic gaskets 28a,b.
Two common designs of synthetic gaskets 28a,b are illustrated in >'igures 3A and 3B; the synthetic gasket 28a of Figure 3A is used with single-door applications, white the synthetic gasket 28b of t=figure 3B is used with double-door applications.
The side panels 22 can be composed of diverse materials, but are preferably composed of AB5 sheeting, which adhere to the generally parallel faces 20 of the door capping 16 and bond with the synthetic insulating material 24 when injected. The side panels 22 can also be composed of stainless steel sheeting, which is desirable in many industrial and retail contexts. The side panels 22 are preferably of the same width as a recess ~2 in the dour capping 96, as can be seen in f=igure 1, allowing far a smooth surface continuity between the side panels 22 and the door capping '16.
2a In the preferred method of assembling the industrial door assembly 7C1, the first step is to weld steel tubing together to form the rigid internal frame 92 to desired specificatParis, along with steel gussets 3D welded in all inside comers. When, the door capping 16 is attached to the rigid intem~af frame 12, preferably by mechanical fastening means. The side panePs 2~ can then be banded to the generally parallel faces 20 of the door capping 16, preferably by a chemicaP
bonding.
As can be seen in Figure 2A, an access means 38 is provided, in this exemplary case a simple drilled hole, through the door capping 16 and the rigid interns!
frame 12, into an inner space (not numbered defined by the rigid intemuf frame 12 and side panels 22. More than one hole may be required for the access means 38 to $e adequate in a given context. The synthetic insulating material 24 is then injected through the access means 58 into and filling this inner space, such that it bonds to the side panels 22 arid provides a firm, strong structure. To enable air within the inner space to escape in response to injection of the synthetic insulating material 24, a vent hole 40 is provided through the door capping 15 and the rigid internal frame 12, although mare than one vent hole 40 may be required. Finally, any door hardware (nit shown) or synthetic gaskets 28a,b can be fitted within the receiving means 26 as desired. Window openings (not shown) can also be cut out of the industrial door assembly 10 once the synthetic insulating material 24 hardens after injection, and windows (not shown) inserted therein.
The utility of the present invention resides in its usefulness in industrial 2f! and retail settings which require strong, insulated doors of various desired dimensions and designs. The present inver~tian addresses this need.
While a particular embodiment of the pr~ssent invention has been descril'ed in the foregoing, it is to be understand that other embodiments are possible within the scope of the invention and are intEnded to be included herein. It will be clear to any person skilled in the art that modifications of and adjustments to this invention, not shown, are possible without departing from the spirit of the invention as demonstrated through the exemplary embodiment. For example, the generally parallel filanges S4. may not be necessary if the core body 32 itself can be designed to directly accept the side panels 22 and be firmly attached to the rigid internal frame '12.
The invention is therefore to be considered limited solely by the scope of the appended claims.

For example, the generally parallel filanges S4. may not be necessary if the core body 32 itself can be designed to directly accept the side panels 22 and be firmly attached to the rigid internal frame '12.
The invention is therefore to be considered limited solely by the scope of the appended claims.
