Over Flow Pan

Abstract

A rain gutter screen assembly for use at portions of a rain gutter where water tends to overshoot. The assembly includes a screen having portions sized to overlie the interior of rain gutter sections and includes an additional screen, screens, solid water directing caps or a combination of such that overlie areas outward from and adjacent to the intersecting portion of a rain gutter. Water flowing from a roof will be captured by the screens, pans, and / or chutes and redirected downward or rearward into the rain gutter. The pan or chutes may utilize attachable or intrinsic hanging elements that attach the pan or chute to the rear wall of a rain gutter.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to a screen assembly for rain gutters and may be adapted to both straight lengths and inside corner portions of rain gutters.[0002]Various assemblies have been proposed to address debris accumulation or water overflow that most often occurs at “inside corners” or intersecting sections of rain gutter lengths.[0003]Two recent prior art assemblies in particular have offered “often effective” but not always effective solutions: U.S. Pat. No. 7,765,743 to Russell Gilford and U.S. Pat. No. 7,805,889 to O. Lynn Barnett.[0004]U.S. Pat. No. 7,765,743 teaches: “a rain gutter screen assembly for use of the inside corner of a rain gutter. The assembly includes the screen having portion sized to overlie intersecting ends of the rain gutter sections . . . and a central portion (of the screen) sized to extend outwardly beyond the outboard edges of the intersecting and in cantilever fashion: and a frame structure mounting outboard edges of the...

AI Technical Summary

Benefits of technology

The invention is a screen assembly that prevents debris from entering rain gutters and redirects water coming off the roof. The screen is strengthened against snow and ice loads and is designed with ridges or channels to improve water redirection. The screen can be easily installed and attached to roofing elements or fascia boards. The water flows through the screen and pan, with the pan providing a damming effect to prevent further water flow and directing water back into the gutter. The technical effects are improved protection of gutters from debris and better water redirection.

Problems solved by technology

Two recent prior art assemblies in particular have offered “often effective” but not always effective solutions: U.S. Pat. No. 7,765,743 to Russell Gilford and U.S. Pat. No. 7,805,889 to O. Lynn Barnett.

Although screen prevents debris entrance, simple screen as taught by '889 provides a rougher surface than the '243 mostly metal design and certain debris in particular such as oak tassels and pine needles often cling to such screens and just stay there.2. It is often difficult to install: Exhibit one shows a cardboard display showcase with the screen inserting beneath cardboard shingles.

In the field, shingles are often curled under, broken at the edges, double or triple layered and very difficult to lift especially in cold weather.

The types of screen used as gutter guard filtration methods, due to their comparative flimsiness, can be very difficult to insert under a straight linear run of shingles L1.

Trying to simultaneously insert a screen beneath a left linear run of shingles L1 and a right linear run of shingles L2 may prove to be more than just “very difficult” or “frustratingly difficult” to install and instead almost impossible to install.

If the screen is preinstalled in the pan installation can be even more difficult because now the installer has to simultaneously position the left lateral edge of the screen the right lateral edge of the screen while ensuring the pan is positioned properly over the front top lips of an underlying gutter.3. Although the '243 patent provided rigid support able to withstand heavy snow loads the '889 “all screen” design does not and can concave under snow and ice loads causing it to disinsert itself from beneath shingles and to concave downward into a recessed pool formation.
