DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(9) The following discussion describes in detail at least one embodiment of the present invention. This discussion should not be construed, however, as limiting the present invention to the particular embodiments described herein since practitioners skilled in the art will recognize numerous other embodiments as well. For a definition of the complete scope of the invention the reader is directed to the appended claims. FIGS. 1 through 6 illustrate the present invention wherein a receiver body for removing moisture from behind an EIFS wall panel system is disclosed and which is generally indicated by reference number 10.

(10) Turning to FIG. 1, therein is shown a perspective view of the present invention 10 wherein a receiver body expected to be made of plastic is shown wherein the body is designed to collect moisture at the drainage plane behind a prefabricated EIFS wall panel system and which body allows moisture to drain toward the outside of the finish wall. The present invention 10 is expected to be installed behind the EPS foam on either the outside or top of the exterior wall sheathing.

(11) The present invention 10 includes a left and right end wall 12, 14 along with a bottom wall 16 and an upper side 18 having a plurality of openings 20 therein which are formed by a series of cross walls 22 running between a rear wall 24 and a forward wall 26 which form the plurality of side by side openings 20. On the front wall 26 near the lower end 16 are a pair of drainage tubes 28 being at least one in number but expected to be a plurality thereof. The drainage tubes or conduits 28 are sized to accommodate the flow of moisture from the present invention 10 depending on the size and shape of the present invention 10 which is installed in the particular job site so as to insure that the drainage tubes 28 are properly sized to effectively drain all of the moisture that collects on the interior of the drainage body of the present invention 10. The present invention 10 is expected to be made of plastic or similar material and its size and shape are to be user selected based on the particular installation and may be installed as a rather long single member, for example, approximately 10 feet long, or it can be comprised of a series of shorter members, for example, 6 inches long, disposed in a side by side relationship to cover the entire width of the particular wall panel system in which it is installed.

(12) Turning to FIG. 2, therein is shown by general reference number 30 the EIFS wall panel system including an outer layer of EPS foam 32, an inner layer of sheathing 34 and a layer being wall stud framing 36 wherein a drainage plane 38 is disposed between the EPS layer 32 and the sheathing 34 wherein the present invention 10 is disposed in a moisture collection space 40 formed between the EPS foam 32 and the sheathing layer 34 where the space is effectively sized to allow the present invention 10 to be disposed therein so that the drainage tubes 28 can be extended toward the outside 42 of the EIFS wall panel system 30 so that any collected moisture 44 can be effectively removed from the EIFS wall panel system 30. Caulked joint 46 is also shown at the point of joinder between upper and lower sections of EIFS. Of course, the caulked joint 46 is shown only to help illustrate the environment of the present invention 10 and has nothing to do with the operation or structure of the present invention 10. Outer layer 35, may include reinforcing mesh, a base coat which forms the inner portion of the outer moisture barrier, or a finish coat, which forms the outer portion of the outer moisture barrier. While these layers 35 are important to an EIFS system, they are not particularly relevant to the present invention 10 because the present invention 10 can be used with or without these layers. Therefore, these layers are shown grouped together as a general outer layer 35. The present invention 10 could be used in and would effectively drain any type of wall panel system which included a drainage plane 38 as disclosed herein.

(13) Turning to FIG. 3, therein are shown the previously disclosed elements of the present invention 10 showing it disposed between layers 32, 34 in the drainage plane 38 so that it can collect moisture in the moisture collecting space 40 then have the moisture pass through the interior of the present invention 10 and out the drainage conduit/tube 28. The moisture collection space 40 is clearly shown and is effectively sized to collect the moisture between layers 32 and 34 and thereby allow the moisture to enter into the present invention 10. The drainage tubes 28 are shown having an effective slope and length to allow passage of the moisture through the tubes and to the outside of the EIFS wall panel system.

(14) Turning to FIG. 4, therein is shown the present invention 10 along with the previously disclosed elements. It should be clear that the present invention 10 could be made as a single elongated member, for example, being approximately 8-10 feet long, or could be comprised of a series of shorter members, for example, 6-12 inches long, disposed in a side-by-side relationship so as to cover the entire width of the particular wall panel system in which it is installed. The cut lines on each end of the present invention 10 are intended to illustrate this in FIG. 4 by showing that it is of indeterminate length and therefore being variable in length.

(15) Turning to FIG. 5, therein is shown the present invention 10 including previously disclosed elements and particularly showing that the present invention 10 has a plurality of openings 20 separated by divider walls 22 being disposed in a side-by-side relationship so as to form and be spread across the entire width of the present invention 10 whether the present invention 10 is formed of a single rather long structure, for example, being 8 to 10 feet long, are a short structure, for example, being 6-12 inches long, the present invention 10 would be constructed in the same manner. It also should be clear that the present invention 10 is disposed proximate the drainage plane 38 between the layers 32 and 34 of the EIFS wall panel system.

(16) Turning to FIG. 6, therein is shown the present invention 10 particularly illustrating that the drainage tubes 28 are effectively slope downwardly so that they will effectively remove moisture which collects in the collection chamber on the interior of the present invention 10. The collection chamber is disposed in the area between the lower terminus of the divider walls 22 and the bottom 16 on the inside of the receiver body 10 adjacent the inlet to the drainage tubes 28.

(17) By way of general explanation and by making reference to FIGS. 1-6, the present invention 10 may be summarized as follows: a method of collecting and removing moisture from an external wall panel system 30 of a building, having the steps of: a) providing the external wall panel system of a building comprising metal stud framing 36 formed by vertically extended spaced stud members, a sheathing layer 34 covering outer edges of the stud members, an outer layer of a rigid closed-cell insulation 32 on an outer surface of the sheathing layer, and a general outer layer 35 covering the insulation; b) a user inserting a receiver body 10 into the wall panel system for removing moisture 44 from an interior of the wall panel system, the receiver body being mounted in a drainage plane 38 between the insulation and the sheathing layer and comprising a rear wall 24 abutting the sheathing layer, a forward wall 26 spaced from the rear wall, with side walls 12, 14, an open top 20, and bottom wall 16 forming an interior of the receiver body; c) forming inside of the receiver body a series of spaced, vertically extending cross walls 22 between the forward and rear walls within the receiver body extending down from a top of the receiver body forming vertical passageways, the cross walls terminating short of the bottom wall forming a collection chamber along the bottom wall; d) forming a collection space 40 in the insulation above the receiver body for allowing moisture to enter top openings into the receiver body; and e) inserting one or more drainage tubes 28 into and extending out from the collection chamber through the forward wall and general outer layer of the wall panel system for draining moisture that collects on the interior of the receiver body. The receiver body 10 of the present invention may be manufactured in many sizes and may be as small as about 3 in height, i.e., the height of the rear wall 24, with a thickness (distance between front 26 and rear 24 walls) of about , wherein the drainage tubes 28 are about in diameter and spaced about 2 apart (side to side), with the divider walls 22 being spaced about apart (side to side).
