It is yet another object of the present invention to provide a flashing apparatus for external use on structures which is economically affordable and available for relevant market segment of the purchasing public.

Other objects, features and advantages of the present invention will become more readily apparent from the following detailed description of the preferred embodiment when considered with the attached drawings and appended claims.

FIG. 1 shows a perspective view of the flashing apparatus as it is shown in use.

FIG. 2 shows a side view of the flashing apparatus as it is shown in use.

FIG. 3 shows a perspective view of the flashing apparatus.

FIG. 4 shows a perspective view of the various flashing apparati that incorporate aspects of the flashing apparatus into them.

With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new flashing apparatus for external use on structures embodying the principles and concepts of the present invention and generally designated by the reference numeral 2 will be described.

As best illustrated in FIGS. 1 through 4 , a number of construction components are utilized in conjunction with the flashing apparatus 2 to show how the flashing apparatus 2 interrelates with these items. First, a stud 4 is shown as structural support for a structure. The stud 4 , in the completed product, would be not be visible, as it serves as a structural framework within the structure. Attached to the stud 4 would be a layer of sheathing 6 and a weather resistant barrier 8 . The sheathing 6 and barrier 8 could very well be incorporated into one item that is then fixedly attached to the stud 4 .

Over the barrier 8 is then attached a plurality of fiber cement siding pieces 10 . Each of the pieces has a length and a width, with the length being much longer than the width. The length of each of the fiber cement siding pieces 10 is at least eight feet long, but can be longer as needed. Each of the fiber cement siding pieces 10 has a width that can vary widely, depending on the manufacturer and the particular use or look desired for a particular structure. Each fiber cement siding piece 10 also has two edges, a top edge 17 and a bottom edge 15 .

When placed against the weather resistant barrier 8 , the fiber cement siding pieces 10 are placed in parallel rows. Normally, when fiber cement siding 10 is placed against the barrier 8 , it is angled in a way that allows the bottom edge 15 of a particular fiber cement siding piece 10 to overlap the top edge 17 of a fiber cement siding piece 10 that is below the first piece 10 . In addition, all of the fiber cement siding pieces 10 on a structure are overlapped in such a manner that the “butt joints,” which are the areas between two adjoining fiber cement siding pieces 10 at the same level, are not at the same “vertical” location for each level. These characteristics ensure that the water dripping down against the exterior of a structure will not easily get behind the fiber cement siding pieces 10 .

However, without the flashing apparatus 2 , it is possible that small amounts of water could get in between adjacent fiber cement siding pieces 10 . However, proper use of the flashing apparatus 2 in conjunction with the fiber cement siding pieces 10 will prevent this from happening.

The flashing apparatus 2 itself comprises a main body 5 and a lip 3 . The main body 5 ideally has a height of six (6) inches and has two edges, a top edge and a bottom edge. The main body 5 also has a width of anywhere between five and one-fourths (5¼) of an inch and twelve (12) inches. The fiber cement siding pieces 10 ideally has width dimensions of one of several different sizes, including 5¼, 6¼, 7¼, 8, 8¼, 9¼, and 12 inch widths.

Attached to the top edge of the main body 5 of the flashing apparatus 2 is the lip 3 . The lip 3 is attached to the top edge of the main body 5 at a ninety degree angle and extends outward approximately one-fourth (¼) of an inch. When each particular flashing apparatus 2 is used in conjunction with two adjacent fiber cement siding pieces 10 , the lip 3 is wrapped over the top edge 17 of each of the fiber cement siding pieces 10 before fasteners 18 are used to fixedly attach the fiber cement siding pieces 10 to the weather resistant barrier 8 .

The lip 3 of each flashing apparatus 2 essentially holds the flashing apparatus 2 in place against the weather resistant barrier 8 and the fiber cement siding pieces 10 , especially before the fasteners 18 have been used to fixedly attach the fiber cement siding pieces 10 to the weather resistant barrier 8 . In addition, the presence of a flashing apparatus 2 over each “butt joint” where two adjacent fiber cement siding pieces 10 meet each other will prevent water seepage through this area, thereby further protecting the weather resistant barrier 8 , the sheathing 6 , and the stud 4 from external moisture problems.

The flashing apparatus 2 itself is preferably fabricated from galvanized steel. The flashing apparatus 2 would come in a variety of colors, depending on the colors of fiber cement siding pieces 10 that are available.

The concept of the flashing apparatus 2 can also be utilized in other various shapes and sizes as well. FIG. 4 highlights various alternative embodiments of flashing apparati 2 that include a base 20 , a bent portion 22 , and a reverse bend 24 portion. The bent portion 22 of each these alternative embodiments is attached at a ninety degree angle to the base 20 , while the reverse bend 24 is attached to the bent portion 22 and wraps around at a one-hundred eighty degree angle. The various flashing apparati 2 shown in FIG. 4 are not to scale, as they generally have lengths of at least eight to ten feet. Furthermore, the width of each of the bases 20 is preferably between two to three and one-half inches and the width of each bent portion 22 is ideally one to two and one-half inches.

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.
