Over Flow Pan
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.
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.
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.
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.
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 screen and defining a plate extending outwardly beyond the outboard edges of the intersecting ends in cantilever fashion an underlying relation to the central screen portion.”
A forerunner of the '743 Inside Corner gutter guard art is found in
'243 teaches that screen exits from beneath shingles but does not travel past the intersecting ends of a gutter. Instead, metal picks up where the screen leaves off with the metal traversing outward past the intersecting ends of a gutter.
The primary differentiating feature between '243 and '889 is that '889 extends an unbroken piece of screen from beneath shingles, then outward and over intersecting ends of gutter lengths with the outboard edges of this unbroken screen being mounted by an underlying pan. (please see Exhibit 1 which embodies the '743 art). A short way to sum up the differences: '243 teaches a cantilevered pan overlain by metal and screen with the screen extending backwards and beneath shingles whereas '889 teaches a cantilevered pan overlain by all screen from the front edge of the pan to beneath shingles.
Deficiencies of the '889 art, noted in the field by installers are:
-
- 1. It tends to trap and hold debris. 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. The '889 art necessitates not just being properly installed in the back which can require overcoming various hurdles but must then be positioned so it is properly installed in the front not leaving gaps between the downward extending terminal edges of the screen in the front upraised sidewalls of the pan. 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. Improved art over the '893 could be achieved by incorporating strengthening or supporting elements to stabilize it's filtering medium as well as by incorporating rigid bands or other methods at the rear of the 893 screen to allow for much improved installation.
- 4. As noted in the marketer's warning MW; the screen has sharp edges.
U.S. Pat. No. 7,805,889 to O. Lynn Barnett teaches an effective inside valley gutter guard for the most part. Our dealers have utilized both the '743 and the '889 inventions and inside valleys with some preferring one over the other and vice versa.
SUMMARYThe invention is directed to and inside corner screen assembly that prevents the entrance of debris into rain gutters and redirects water cascading off of the roof valley downward into the gutters.
The screen gutter assembly is for use at an inside corner formed by intersecting rain gutter sections and is secured to the rear walls of the rain gutter sections and/or to the fascia boards they are mounted on.
The screen gutter assembly includes a pan or bridging channel that overlies the open airspace present forward and beyond, and to the sides, of the intersecting ends of gutter lengths. The pan or bridging channel underlies screen or filtering elements that distend from an area beneath or adjacent to roofing elements toward the pan or bridging channel.
The pan includes attached or adjacent upwardly extending elements that contact the underside of the screen or filtering elements to add support against deformation and collapse.
The screen or filtering elements are banded by or are adjacent to solid structures that serve to strengthen and/or strengthen and support the screen or filtering elements against collapse under snow or ice loads and that further serve to direct water to a chosen direction.
The screen or filtering elements are sectionalized into rear ward and forward segments and or left and right segments which allows for easier installation of the filtering elements and improved water redirection by means of ridges or channels or height variation among the filtration and pan components.
Metal or other material banding of the rear terminal areas of screen or filtering elements allows for easier insertion beneath roofing elements or for easier attachment to fascia boards.
Water flowing off a roof's inside Valley will initially contact filtering material or solid material with water directing features or a combination of both and then be directed downward into an underlying rain gutter. Amounts of water not so directed will channel toward the bridging channel or pan either of which has upward extending sidewall members which provide a damning effect that stops any further forward flow of water. Water is then redirected along the bottom surface of the bridging channel or pan backward into the rain gutter.

Planes 3G and 3H, which serve as attaching arms (to the rear of the gutter via tabs 3I and 3J) may be of any functional height. The same is true for plane 3F which serves as a final stop gap against forward water flow coming off a roof's valley area 4. The dimensions of the pan may be increased or decreased as needed dependent on gutter size (5″, 6″, etc . . . ) and/or the amount of water that may channel down the valley.

Alternate Embodiments
Pan 3 in any of its embodiments illustrated in
Exhibit 4 illustrates a simple employment of the art of the present invention: SP1 would be a screen portion with front and rear downward extending planes DEP1 and DEP2. This small platform in and of itself can withstand heavy snow load with screen of sufficient stiffness or with a combination of micro-mesh over expanded metal as the material being used. (such an embodiment is presently being tested in the field). REP 2 represents a solid metal band attached to the rear of SP1 and beneath the forward terminal edge of SP2. This ledge (REP) Significantly improves the filtering mediums ability to withstand snow and ice loads preventing concaving of the screen. Banding (represented by the dotted lines pointed to by 4C) the left and right rear terminal edges of SP2 which insert beneath roofing elements L1 and L2 helps with installation by preventing deformation of the flimsier (by comparison) screen that can occur when attempts are made to insert plain screen beneath shingle edges. A thin metal is preferred for banding material to decrease shingle lift and to allow for easy notching of the rear terminal edges of SP2 when necessary (to allow for nails nailed through starter course shingles that are sometimes improperly nailed within an inch or less of a sub roof's terminal edge; such nails making the lifting of the starter course almost impossible without causing a tear in it.
