An elongated strip of extruded plastics material includes a vertical rear plane adapted to seat on the rear portion of a gutter-hanging bracket. The rear vertical plane integrally connects to a second forward extending plane that joins, by means of an underlying u-shaped channel, a v-shaped perforated third plane that forces water to pool and drop through the perforations. The third plane joins, by means of an underlying u-shaped channel, a flange that projects outwardly for retaining the strip to a gutter. A filter configuration comprised of a debris repelling membrane, overlying a skeletal structure of ellipsoid rods spaced and resting on vertical planes, serves to break the forward flow of water and to channel water onto and through its integral perforated horizontal plane. The filter configuration is readily inserted into the u-shaped channels existing on the forward and rear edges of the v-shaped perforated third plane. A filter assembly is provided including a filter membrane and a skeletal structure. The filter membrane defines a first surface and a second surface. The skeletal structure is provided beneath the filter membrane and is bounded by longitudinally extending ends. The skeletal structure includes a perforated plane spaced from the first surface of the filter membrane, and a first leg disposed on the perforated plane intermediate the longitudinally extending ends and extending along a length of the skeletal structure above the perforated plane. The first leg extends toward and contacts the first surface of the filter membrane, whereby when the filter assembly is installed in the open top of a rain gutter, water flowing across the filter membrane in a direction normal to the length of the skeletal structure is redirected downward by the first leg through the perforated plane and into the rain gutter. A gutter shield is provided for mounting in an open top of a rain gutter, the gutter shield including an elongated body adapted to receive the filter assembly.

THE DRAWINGSmembrane configuration 32.

FIG. 9 illustrates that rear horizontal leg 20 also may serve as a locking mechanism due to its positioning beneath hex-head or other screw fasteners 30 used to secure a hidden hangar and rear of a rain gutter to a fascia board in such instances when hidden hangars are the chosen method of fastening. It can be seen in FIG. 9a that rear horizontal leg 20 may also serve as a platform on which a mesh or other type filter 31 approximately ¾ to 1½ inch wide and one inch tall may rest to provide a rear barrier to debris that may possible be wind blown to the rear of the gutter protector body.

Referring, again, to FIG. 1 it can be seen that the extruded gutter cover body includes a rear support leg 19 that serves to provide rear vertical support for the gutter cover body and which includes “score lines” 21 which an installer may score with a utility knife or other scoring device if necessary. Such scoring will prevent running cracks up the rear support leg 19 from occurring if the rear support leg should ever need to be notched out to fit over a gutter spike that may be positioned too high through or above the rear of a rain gutter. In practice, in the field, improper positioning of the gutter spike occurs infrequently and may cause the gutter cover body to rest unevenly at varying heights inside the rain gutter necessitating that the rear support leg 19 and rear horizontal leg 20 be notched out to allow the rear of the gutter cover body to rest in a lower position inside the rain gutter to maintain an attractive low profile and smooth even-plane transition from section to section of the body of the present invention.

Referring again to FIG. 1, rear support leg 19 of the extruded body extends vertically upwards at an approximate 85-degree angle and an approximate 0.6-inch length. Support leg 19 then bends forward at approximately a 75 degree to 95-degree angle to form a shelf 23 approximately 0.2 inches in length. Shelf 23 extends upward approximately 90 degrees forming vertical leg 18 with an approximate length of 0.21 inches. Vertical leg 18 then angles forward approximately 90 degrees into a higher shelf 17 whose approximate length is 0.3 inches.

Referring now to FIG. 10 it is seen that bottom shelf 23, vertical leg 18, and higher shelf 17 of the extruded body form a recessed “receiving” channel 22 approximately 0.2 inches in depth and 0.07 inches wide which may serve to receive plastic or metal inserts or fasteners 27 that may be used to create a rear to forward tension mount of the extruded body.

Referring now to FIGS. 12 and 12a, it is illustrated that channel 22 may additionally may serve to act as a the first of two receiving channels of the extruded body 1, the second receiving channel being channel 23 24 that may receive and hold fast and permanently an aluminum, zinc, or copper metal cover 35 that may be clipped onto the extruded body 1.

This clipped on cover 35 may serve to join two extruded body pieces together by spanning and covering the joint formed at their side-by-side abutment when such pieces are installed in a rain gutter. This clipped on cover 35 may further serve to provide fungicidal properties when made of zinc that would discourage moss mold or mildew growth on the invention, which is an improvement, not found in prior art. The clipped on cover 35 may further serve to allow color and material matching of the plastic extruded body to aluminum, copper, and other metal rain gutters which is an advantage and property not found or suggested in prior art. The co-use of two such materials, polymer and metal, in a leaf guard on copper or other expensive metal rain gutters would provide a great economical alternative to the use of solid copper leaf guards which naturally employ thicker and thereby more expensive copper in their design. The dimensions of such an extruded 0.019 or thinner metal cover would be such that it's underside 36 would be approximately 5 percent to 15 percent greater than the exterior portion of the extruded plastic body of the invention it covers. Such extruded metal cover may also serve to act as an extension for the plastic extruded body it covers to allow for a fit rain gutters larger than standard 5″ K style gutters by widening the clip on metal shelf 35 to accommodate 6 inch or wider rain gutters.

Referring again to FIG. 1, shelf 17 extends horizontally 0.3 in. and then upward into a curve 2a such curve having an exterior radius of approximately 0.137 and an interior radius of approximately 0.073 inch. The reverse of curve 2a of the extruded body extends forward in a somewhat horizontal plane 2 angled downward approximately 5 degrees for a distance of approximately 1.5 to 1.75 inches. Horizontal plane 2 embodies a small recessed channel 59 across its entire length of sufficient depth to allow for scoring and breaking of the horizontal plane.

FIG. 13 illustrates such scoring and breaking of recessed channel 59 may be optionally employed by the installer in instances where a horizontally compressed rain gutter does not allow for easy installation of the invention: the severed rear portion 36 of the extruded body 36 1 may then be placed over the front severed portion 37 of the extruded body 37 1 as illustrated in FIG. 13 and affixed by polymer cement or fasteners such as plastic bolt 38 and plastic nut 39 creating such overlap distance of the rear severed portion 36 of the extruded body 1 over the front severed extrusion portion 37 of the severed extruded body 1 as the installer deems necessary to create an ideal adjusted extruded body width for placement in a horizontally compressed portion of a rain gutter.

Referring again to FIG. 1, Horizontal plane 2, after extending a distance of approximately 1.5 inches, will then “fork” into two extensions: one extension; 3, continues to extend outward angled downward from the 1.5 inch point an additional 5 to 10 degrees to form a top shelf approximately 0.28 inch in length. The other extension 4 of Horizontal plane 2 extends downward at an approximate 85 degree angle for a distance of 0.125 inches and then angles forward 90 degrees into a plane 16 approximately 0.28 inches in length. Extension 3, extension 4 and plane 16 form a recessed “receiving” channel 24 with a depth of approximately 0.28 inch and a width 55 of approximately 0.125 inch which serves to secure the edge of the multi level filter portion filtration configuration 32 of the invention and to receive, if opted for, the curved edge of a metal cover 35 which may be clipped onto Curve 2a, Horizontal plane 2, and extension 3 as illustrated in FIG. 12a.

Referring again to FIG. 1; Plane 16 of the extruded body continues and then angles sharply downward at an approximate 80 to 85 degree angle for a distance of approximately 0.4 inches to form plane 5. Plane 5 extends downward and then angles forward at an approximate 22-degree angle-forming plane 15. Plane 15 has an approximate length of 0.94 inch and is perforated as illustrated in FIG. 2 with perforations 0 approximately 0.065 inch wide, 0.125 long. Perforations 0 are aligned end-to-end and spaced approximately ¼ inch apart in rows, which extend the length of the extruded body, such rows being spaced approximately 0.145 inch apart.

Referring again to FIG. 1, Plane 15 forks into an extension and a continuance: the extension of plane 15 is plane 6 which extends upwards as an extension of plane 15 at an approximate 90 degree angle. Plane 6 will act as a support for the insertable filter portion of the invention and presents an improvement not found in prior art in that it will act as a dam that forces water to back up and drip through the rear most rows of perforations of plane 15 rather than continue forward with enough speed and depth of water flow to spill over the front lip of the rain gutter 33. Such occurrence of water spill is common in prior art, which relies solely on water adhesion principals. Planes 5, 15, and 6 of the extruded body 1 form a water receiving well with a perforated bottom shelf 15 that will direct water into a rain gutter 33 when acting in conjunction with the water dam formed by plane 6 as described in the preceding sentence. Referring again to FIG. 1, Plane 15, in addition to forking upwards into plane 6 also continues on at an approximate 22 degree upward angle beginning at the base of Plane 6 and extends into a perforated plane 13 approximately 0.95 inch long. This angling upward of plane 13 toward the front lip of the gutter 33 presents an improvement not found in prior art in that water which contacts plane 13 will not continue on a forward flow toward the top front lip of a rain gutter 33 due to water adhesion principals where it may then spill outside the rain gutter 33. Instead, the water that contacts plane 13 will follow the downward angling plane 13 and be more surely and intentionally directed into a rain gutter 33. The perforations 0 of plane 13 are identical to those of plane 15: 0.065 inch wide, 0.125 long, each perforation spaced end to end approximately 0.25 inches aligned in rows the length of the extruded body 1 such rows being spaced approximately 0.145 inch apart. Plane 13 extends forward approximate 0.95 in and then angles downward approximately 16 degrees into plane 12. Plane 12 extends forward approximately 0.33 inch at which point it forks into an extension and a continuance: the extension, plane 7, forks upward at an approximate 80 degree angle for a distance of approximately 0.14 inch at which point plane 7 terminates in a “T” configuration. The “T” configuration has a rearward (toward the rear of the extruded body) horizontally extending section, plane 8, having a length of approximately 0.25 inch. Receiving channel 24a 25 is formed by planes 12, 7, and 8 and such channel has an approximate width 56 of 0.125 inch. This channel acts to receive and secure the forward edge 54 52 of supporting skeletal filter component 57 43 as illustrated in FIG. 8. The forward extension of the “T” is an extending plane, 9, that angles approximately 7 degrees downward for a distance of approximately 0.757 inch where it then angles downward 45 degrees into plane 10, which measures approximately 0.45 inch in length. The continuance of plane 12 is for a distance of approximately 0.24 inches after its vertical fork; , plane 7 giving plane 12 a total length of 0.57 inch.

Referring again to FIG. 1 it may be seen that planes 6,13,12,7, and 8 form a receiving well of the extruded body which will direct rain water through its perforations 0 into a rain gutter 33. FIG. 1, planes 12,7, and 8 further illustrate a recessed receiving channel 24 25 that may receive and secure both an inserted edge of the multi filter filtration configuration 32 employed by the invention as is illustrated in FIG. 7 and FIG. 8.

FIG. 12a illustrates that a “clip on” metal cover 40 may be inserted over planes 8, 9, and 10 to achieve an optional aesthetic matching of colored aluminum or copper between the present invention and the underlying gutter it protects and/or to achieve the improvements previously described in the last sentence of page 4 and the fist sentence of page 5 of this disclosure.

FIG. 11 illustrates Channel 22 may serve as a receiving channel for polymer, metal, or other semi-flexible formed or extruded inserts with profiles similar to extension 41 which may be placed or affixed with adhesives into Channel 22 and may then serve as an extension of the extruded body 1 which extends rearward and compresses against the rear wall of a rain gutter, hidden hangar, or fascia board to create a rear to forward tension mount of the extruded body into the rain gutter at the discretion of the installer. The amount of mounting tension created may be varied by the length of the top shelf 42 of the extruded or formed extension 41.

Referring now to FIG. 3 there is illustrated the profile of a perforated filter skeleton 43. The width of filter skeleton 43 is approximately 2.5 inches and is an extruded polymer of approximately 0.04 to 0.06 inches. Plane 44 is approximately 0.58 inch and contains perforations 0, such perforations being of elliptical shape approximately 0.45 inches long and 0.22 inch wide. The perforations 0 are positioned as close to vertical leg 45 as possible and have a wider top opening than bottom creating a taper which more readily captures and directs rain water than a simple straight through punch. Horizontal plane 44 t-junctions into vertical leg 45 whose approximate length is 0.35 inch. Leg 45 has a curved bottom 46, such curved surface facilitating the dropping of water off of leg 45 downward into the rain gutter. Leg 45 is capped by ellipse 47. Ellipse 47 has dimensions of approximately 0.13 inch width and 0.08 inch height.

The elliptical curved surfaces 47 resting on vertical legs 45, create water-channeling paths that exhibit siphoning effects stronger than has been realized in prior art. These “t” configurations, as well as their approximate spacing of 0.19 inch from subsequent ellipses and legs, create act as an ideal support for warp-knitted filter membrane 50 (shown in FIG. 5 in an exploded view): Such “t” configurations, and their spacing, enhance the self-cleaning properties inherent in filter membrane 50. Additionally, they present a breaking of any water channeling paths to the front of a rain gutter lip noted in prior art.

FIG. 6 illustrates that filter membrane 50 will be affixed to filter skeleton 43. The downward curves and spacing of the ellipses 47 offer an improvement over prior art in creating multiple curved surface water channels that direct toward a vertical leg resting on a horizontal perforated plane that employs downward extending legs to continue the flow of water downward rather than forward. This configuration creates stronger siphoning action than is created in prior art relying on elliptical ocean-wave shapes to channel water or downward extrusions positioned beneath perforations or screens. The channeling of water almost fully around an ellipse that is broken by a vertical downward extending leg better captures water and directs it downward preventing back-flow of received water against incoming water noted in prior art. Vertical legs 45 downward extensions beneath planes 44 and 48 ensure the water adhesion of flowing rain water is broken at the most opportune moment to ensure the directed flow of water into a rain gutter. Perforated planes 48 are approximately 0.25 inches in width. Viewing from right to left, the extruded filter skeleton continues from the first vertical leg 45 whose length is approximately 0.35 inch into an upward extension where it terminates into an ellipse 47. Vertical leg 45 is intersected approximately 0.2 inch down by forward extending perforated horizontal plane 48. Planes 48 are approximately 0.25 inches in length.

Perforated plane 48 continues forward until it intersects the second vertical leg 45 approximately 0.2 inch below ellipse 47. Vertical leg 45 extends approximately 0.22 inch downward from perforated plane 48 in order to break any surface tension of water adhering to perforated plane 48 and redirect it downward into a rain gutter. A second perforated plane 48 extends forward horizontally from a second vertical leg 45 until it intersects a third vertical leg 45. Third vertical leg 45 is capped by an ellipse 47 as are all vertical legs of filter skeleton 43. A third perforated plane 48 extends forward horizontally from third vertical leg 45 until it intersects a vertical leg 51 whose length from ellipse 47 to it's lower most surface 46 is approximately 0.45 inch. A fourth perforated plane 48 extends forward horizontally from vertical leg 51 for a distance of approximately 0.25 inch where it then right angles upward into a vertical leg 54 whose approximate length is 0.2 inch. Vertical leg 54 extends upward into an ellipse 47. Directly beneath the ellipse which caps vertical leg 54, a horizontal perforated plane 55 52 extends forward for a distance of approximately 0.45 inch. Planes 44 and 52 each have the endmost section of their length non-perforated to allow space for a sewing seam. filter Filter membrane 50 will be sewn onto filter skeleton 43 at these endmost sections of planes 44 and 52.

Referring to FIG. 3 and viewing supporting skeletal component 57 43 left to right: each combination left to right of ellipse 47, vertical leg 54, perforated plane 48, vertical leg 51, ellipse 47 and of ellipse 47, vertical leg 51, perforated plane 48, vertical leg 45, ellipse 47; and of ellipse 47, vertical leg 45, perforated plane 48, vertical leg 45, ellipse 47, creates water receiving wells whose components (by means of their structural configuration and spacing) act to slow the flow of rainwater as well as capture and direct rain water downward into a rain gutter 33 in an improved manner over prior art. It can be seen in FIGS. 3 and 4, that planes 44 and 52 are positioned on higher planes than planes 48. This is done to allow the top of the elliptical planes 47 to remain on a level or slightly recessed plane with planes 3 and 8 of the extruded body as illustrated in FIG. 11. This will disallow a damming effect that could lead to debris build up behind the insertable filter and encourage debris to fall or be wind blown off of the invention.

It can also be seen in FIG. 11 that, viewing from right to left, the third vertical leg 45 abuts the upward extending leg 6 of the extruded body. This feature discourages the product from shifting. Referring again to FIG. 3 it can be seen that, viewing from right to left, the forth leg 51 is of greater length than the preceding downward extending legs 45. The length of leg 51 is approximately 0.48 inch. This illustrates that the length of legs may vary to prevent forward flow of water to the front of the gutter by decreasing water tension paths along the bottom of the filter membrane. The ellipses, too, may exist at different planes which would further facilitate the capturing of rainwater and the direction of it downward into the rain gutter.

Referring again to FIG. 3 it is seen that vertical leg 54 does not extend beneath perforated plane 48. The reason for this is illustrated in FIG. 7 where it is seen that extending vertical leg 54 beneath the plane 48 would cause the filter skeleton to rise above a level or slightly recessed plane than exists between 3 and 8 of the extruded body. An extension of vertical leg 54 beneath perforated plane 48 would cause it to contact plane 13 and push the filter skeleton upwards. The vertical height of vertical leg 54 is approximately 0.17 inches from its bottom most surface up to the point it contacts ellipse 47.

FIG. 5 is an exploded view of filter membrane 50, the type of filtration fabric illustrated affixed to filter skeleton 43 as illustrated in FIG. 6. It can be seen in FIG. 5 that small cylindrical threads of polymer extrusion 55 are made to pass through larger threads 56. This unique method of fabric formation offers an improvement over prior art in that this configuration of smaller curved surfaces passing through, rather than woven or knitted above and beneath larger threads, increases the fabric's ability to capture and direct water. This method of fabric formation offers another improvement over prior art in that it encourages dirt and debris to be less likely to be retained by the fabric and therefore less likely to clog the filtration cloth than other filters employed in prior art: woven, weaved, knitted, non-woven lofty, are able to accomplish. The largest distance between any two larger threads is to be less than 8/100 of an inch, which prevents the smallest of debris from lodging within an open (space between threads. The preferred embodiment of this invention is illustrated in FIG. 9 and FIG. 12a.: An extruded polymer body with extruded multi level filter that employs water receiving channels framed by curved ellipses resting on vertical supporting, lower extending legs covered by a filtration cloth as illustrated in FIG. 5 and FIG. 6 with a slide on or clip on metal covers as illustrated in FIG. 12a.

Referring to FIG. 9, there is illustrated the present invention: a gutter protection system that consists of a main body 1 and an insertable filter skeleton 43 covered with a filter membrane 50. Filter Membrane 50 is composed of intersecting threads. (An exploded view of the interconnecting structure of the threads is illustrated in FIG. 5).

Referring to FIG. 10 The present invention is illustrated as inserted into the top water receiving opening of a k-style rain gutter 33 and resting on a gutter hangar 28. It is illustrated that the present invention rests wholly beneath the sub roof 60 and roofing membrane 61 of a building structure.

Referring to FIG. 12, it is illustrated that the present invention will be affixed to an existing rain gutter in two stages. First, a main body 1 will be placed inside the open top of a rain gutter and then may be secured in place by several means: Rear horizontal leg 20 will rest upon a hidden hangar 28 and prevent body 1 from displacing by locking beneath the head of fastening screw 30. The front of the present invention is snapped into place and secured to the front lip of the k-style gutter by planes 9,7, & 11 of the body.

Sub-heading 1

Covering of Joints, Aligning of Adjoining Sections, and Color Matching

Once this is accomplished, main body 1 offers improvement over prior art in offering a method of aligning adjoining sections of the invention in a manner that allows joints between adjoining body members to be covered. This covering of joints and joining of abutted sections of the invention is accomplished by means of a roll-formed or “braked” sleeve (see FIGS. 12 and 12a, sleeve 35). The resulting absence of debris-allowing joints is not realized in prior art intended to retrofit existing rain gutters.

Referring FIG. 1, there is illustrated a recessed channel 22. Recessed channel 22 acts as the first of two receiving wells 22 & 24 for a roll-formed or job-site “braked” metallic cover 35 which may be clipped onto the top shelf 2 of the present invention (see FIGS. 12 & 12a). This feature offers improvement over prior art in that no prior art offers the ability to specifically color match to it's underlying rain gutter at the time of installation. The present invention allows the installer to quickly break matching gutter coil to clip into and cover top shelf 2 and top shelf 9 as is illustrated in FIG. 12a. Metallic sleeves 35 & 40 may also serve to further align each sectioned body of the present invention and maintain consistent edges and heights between adjoining bodies. This is an optimal method of ensuring consistency of height and edge alignment between adjacent sections not known in prior art.

Sub-heading 2

Vertical Height and Horizontal Width Adjustments

Another improvement achieved by the present invention, not known in prior art, is its ability to provide a means of extending body width to accommodate standard sized commercial sized gutters with 4, 5, 6, and 7 inch widths. Widening may be accomplished by breaking or rollforming the metal cover 35 (FIG. 12a) to a width wide enough to effectively extend the present invention's body rearward.

Sub-heading 2a

Vertical Adjustments

In the event body 1 is installed in a rain gutter affixed to a fascia board by gutter spikes, the present invention offers an improvement not found in prior art by offering a quick, at-the-point-of-installation, method of adjusting the height of the body to ensure it remains consistent. The body 1 of the present invention offers improvement over prior art by allowing for adjustment of it's rear vertical leg 19 by scoring and breaking of the rear leg at points 21. It is known gutter spikes, often employed to secure a rain gutter to a fascia board, are driven in and remain at uneven heights at the rear of the rain gutter. Prior art, which requires a supporting of a rear leg or rearward part of invention body, has not foreseen or allowed for simple height adjustments to be made, which would accommodate prior art bodies to supporting, gutter spikes. Such adjustments may be necessary to maintain a consistent level height of gutter protection units for cosmetic as well as functional reasons.

The improvement accomplished by the present invention is that such height adjustment may be accomplished quickly at the point of installation with a simple blade (to score point 21) and pair of scissor snips to clip the rear leg structure from rear horizontal leg 20 up through rear vertical leg 19 to the scored recess 21. The scored mark ensures that the portion of rear vertical leg 19 so scored and cut will break off easily. Prior art does not allow for such simple controlled height adjustment at the point of installation (possibly while the installer is on an extension ladder).

Width Adjustments

The body 1 of the present invention offers another improvement over prior art designed to be inserted into the top of a rain gutter, rather than rest upon the top surface of a subroof or roofing membrane, such as U.S. Pat. No. 6,134,843 to Tregear, U.S. Pat. No. 5,619,825 to Leroney, etc,. by allowing for adjustment of the main body by means of a pre-scored recessed channel 59 (FIGS. 2 & 13). Scoring of channel 59 allows the clean breaking and refastening of the body 1 to achieve a means of adjusting the present invention to accommodate both 4 inch and 5 inch gutters. FIG. 13 illustrates that the body 1 of the present invention may broken, then rejoined in a fashion that creates shorter body widths to accommodate the varying widths of a single run of gutter length. It is known that lengths of installed gutter seldom maintain a consistent width due to irregularities in fascia boards they are attached to. Prior art such as is illustrated in U.S. Pat. No. 5,495,694 to Kuhns, U.S. Pat. No. 5,459,965 to Meckstroth, etc., that require a resting of their body on top of or directly beneath shingles or other roofing materials do not have an intrinsic ability to accommodate varying gutter widths. This leads to such prior art presenting an uneven appearance along their rear edges which varies with the uneven width of a gutter they are attached to. This unevenness of edges at the rear of such products, as well as the dipping of subroof structures that often occur beneath the shingles such prior art may rest upon or be affixed to, allows open air spaces to exist at the rear of such products or from side-edge to side-edge of adjoining pieces. Debris may then enter through into a rain gutter or become trapped in the open air spaces. Because this problem is known, installers of prior art are known to screw the rear of such products into their underlying supporting roof structure, which can present the potential for roof leaks and the voiding of roofing manufacture warranties.

Prior art has offered limited adjustment of width, usually by relying on body tension to extend width, as illustrated in such prior art as U.S. Pat. No. 5,619,825 to Leroney, but such extension of body width found in prior art is meant only accommodate one gutter width i.e.: 5 inch or 6 inch and does not allow for utilization of prior art over a span of varying standard gutter widths. Added width of span accomplished by tension weakens the strength of such invention's affixture to the raingutter since the pressure of tension is weakened. Prior art does not allow for the shrinking or widening of body width offered by the present invention in such fashion as to allow installations on narrower gutter widths than 5 inch or as to allow consistently secure installations on wider gutter widths than 5 inch.

Prior art that does allow for installation on varying standard gutter widths such as is found in U.S. Pat.. No. 5,660,001 to Albracht and U.S. Pat. No. 5,640,8090 etc, is undesirable because of the required securing of such prior to or beneath roofing membranes, which has been found to cause failures of roofing membrane integrity.

Water Receiving Wells

Referring again to FIG. 2 it is illustrated that the body 1 incorporates two recessed perforated planes 13 & 15, separated by a vertical leg 6. Both planes angle downward and inward into the body of an underlying raingutter. This allows the present invention to offer improvement over prior art as follows:

Referring to FIG. 1: there is illustrated two recessed water-receiving perforated wells 15 and 13, which direct water, flow downward to a vertical leg 6. The downward angle of perforated well 13, away from the front lip 9 and front lip of a rain gutter offers improvement over prior art U.S. Pat. No. 5,595,027 to Vail, U.S. Pat. No. 5,956,904 to Gentry, U.S. Pat. No. 5,619,825 to Leroney, U.S. Pat. No. 4,841,686 to Rees, U.S. Pat. No. 6,134,843 to Tregear, and other prior art in that it forces water to cease any forward flow to the front of a rain gutter where it may spill past the raingutter as has been noted in prior art. Prior art has not effectively dealt with this noted problem. Reverse curved and hooded gutter protection methods such as U.S. Pat. No. 5,491,998 to Hansen do redirect water flow rearward into the raingutter but have not recognized the noted tendency of debris to follow the water around the curved surfaces they employ into the rain gutter as well. Additionally, such prior art is known to lose most of it's water adhesive properties over time as pollen, oil leaching from asphalt shingles, and other pollutants, coat and remain on the curved surfaces such prior art employs. Downward sloping plane 15, also, prevents forward flow and resulting spilling of water to the ground, by acting in conjunction with vertical leg 6. Vertical leg 6, serves the dual purpose of acting as a center and downward water channeling support for the filtration membrane 50 and Skeleton 43 (See FIG. 9), and as serving as a dam that slows forward rushing water in recessed well 5,15,6 to slow and drain through the perforated plane 15.

Filter Membrane and Skeleton

Once installation and, if necessary, adjustment of the body and/or covering of the body 1 of the present invention is achieved, a filter membrane and skeleton will then be inserted into the recessed channel of the present invention. (See FIG. 2, then FIG. 8 and FIG. 9).

Several improvements over prior art are offered by the filter membrane and skeleton employed by the present invention:

Sub-heading 4a

Filter Skeleton

Referring now to FIG. 3 there is illustrated a filter member: a multi-level supporting structure upon which a wire or cloth membrane composed of intersecting threads shall rest. Prior art employing filtration cloth or membrane, which rests over open apertures e.g.: U.S. Pat. No. 5,595,027 to Vail, U.S. Pat. No. 5,956,904 to Gentry, U.S. Pat. No. 5,619,825 to Leroney, U.S. Pat. No. 4,841,686 to Rees, U.S. Pat. No. 6,134,843 to Tregear, etc. exhibits a property of preventing rainwater from entering the open apertures beneath the filtration cloth. In practice, in the field, it is often observed that volumes of water will travel around the underlying perforations, beneath the filter cloth or membrane covering them, due to water adhesion principals. The water will then feed toward the front of prior art, rather down beneath it and into a rain gutter, and will flow past the top front lip of a rain gutter.

This common occurrence in prior art occurs for several reasons.

Perforated surfaces existing in a single plane, such as is employed in U.S. Pat. No 5,595,027 to Vail, or as exists in the Commercial Product SHEERFLOW. RTM. Manufactured by L. B. Plastics of N.C., and similar prior art tend to channel water inventions sought to correct this undesirable property by either tapering the rim of the open perforation and/or creating downward extensions of the perforation (creating a water channeling path down through open air space) as exhibited in prior art U.S. Pat. No. 6,151,837 to Ealer, or by creating dams on the plane the perforations exist on, as exhibited in prior art U.S. Pat. No. 4,727,689 to Bosler. Such prior art has been unable to ensure all water would channel into the underlying rain gutter because the water, that did, indeed, travel through the open apertures on the top side of these types of perforated planes or screens, would also travel along the underside of the screen wires or perforated planes, as it had on top of these surfaces, and still continue it's undesirable flow to the front of the invention and front lip of the underlying rain gutter, due to water adhesion. Additionally, this “underflow” of water on the underside of the perforated planes and screens illustrated in prior art exhibits a tendency to “back flow” or attempt to flow upwards through the perforations inhibiting downward flow of water. This phenomenon has been noted in practice, in the field when it has been observed that open air apertures appear filled with water while accomplishing no downward flow of water into the underlying rain gutter.

Other inventors sought to eliminate this undesirable property by employing linear rods with complete open air space existing between each rod, This method of channeling more of the water into the rain gutter exhibits more success on the top surface of such inventions, but it fails to eliminate the “under channeling” of rainwater toward the front of the invention due to the propensity of water to follow the unbroken interconnected supporting rods or structure beneath the top layer of rods.

Referring again to FIG. 3, the structure of the present invention improves the flow of water into the rain gutter over prior art, significantly, as has been observed in practice, in the field. This improvement is accomplished by allowing cylindrical rods 47, with unbroken air space existing between them, to rest upon vertical leg supporting structures, which disallow any connecting path for forward water channeling due to water adhesion. Supporting structures 45, 46, 51, & 54 are, indeed, each connected to the other by perforated planes 48. However, this connection is broken by several factors, which disallow a forward flow of water. Water, instead, is forced downward into the rain gutter with no water adhesive path toward the front of the invention existing. This is accomplished by resting the rods 47 on slim vertical supports 45,46,51,& 54. Doing so creates a “t” configuration unlike the simple rod structures of prior art. The present invention is an improvement in two instances: First, water that channels around simple rods, rather than “t” structures exhibits less siphoning action due to the water colliding on the underside of the rod after traveling down the opposing curved sides of the rod. This collision of water slows downward water flow by creating a back flow or upward flow of water against the rainwater attempting to channel downward along the curved surfaces of the rod. The “T” configuration of the present invention prevents such reverse flow or back flow of water against the incoming water flow by creating a continuing path of water flow away from water traveling down the opposite side of the “t”. This allows the filter skeleton 43 to create a stronger channeling or siphoning action on the incoming rainwater than prior art is able to exhibit.

The “t” configuration also offers improvement over prior art because it creates an absolute break in the water adhesion flow on the bottoms of vertical legs 45, 46, 51, & 54. Water which will travel down rods 47, then though the open air apertures 0 which exist in planes 48, will next adhere to and travel down the lower (beneath planes 48) portions of the vertical legs of the “t”. Water traveling down the vertical legs, at this point, is an improvement over prior art such as U.S. Pat. No. 5,595,027 to Vail, U.S. Pat. No. 5,956,904 to Gentry, U.S. Pat. No. 5,619,825 to Leroney, U.S. Pat. No. 4,841,686 to Rees, U.S. Pat. No. 6,134,843 to Tregear, because it has discontinued it's forward flowing path on the underside of the perforated plane, as is common in the prior art, and is now being channeled, again, downward toward the inside of the rain gutter. Prior art, U.S. Pat. No. 4,745,710 also temporarily accomplishes this downward flow utilizing it's rod-supporting structure, but not nearly as effectively due to the interconnection of the underlying support structure, which provides a forward flowing water path by means of water adhesion along an unbroken surface. The improvement of the “t” configuration over prior art is again accomplished by a third, completely disconnected path of water flow, achieved at the lower termination of the vertical legs 45, 46, 51, & 54. Water, at these points, may only flow downward into the rain gutter. This is due to the length of the downward extensions of the vertical legs, which, by design, disallow backflow of water on the underside of the perforated planes 48, or forward flow of water along a water adhesion path to the front lip of the rain-gutter.

Filter Skeletal structure 43 of the present invention creates a siphoning action and ensures a downward, rather than forward flow of water not exhibited by prior art. Referring to FIG. 5 there is illustrated a cloth or wire filter membrane 50, which employs intersecting threads. This membrane exhibits an improvement over other filtering and screening methods illustrated, representatively, in prior art U.S. Pat. No. 5,595,027 to Vail, U.S. Pat. No. 5,956,904 to Gentry, U.S. Pat. No. 5,619,825 to Leroney, U.S. Pat. No. 4,841,686 to Rees, U.S. Pat. No. 6,134,843 to Tregear, etching that it exhibits no tendency to trap and hold debris. The above mentioned prior art, even when employing micro-aperatured cloth, (due to adhesive actions of pollen, oil, pollutants, and silica dust which tend to heal over such products and remain impervious to cleaning by wind or water) has been observed, in the field, to clog due to tendencies to trap and hold debris, thereby channeling water past, rather than into the under lying rain gutter.

Sub Heading 4b

Filter Membrane

Prior art, though naming filtering medium as cloth or screen or tangled mesh, has not recognized or utilized the improvements offered by a filtering membrane accomplished by the intersection of material of equal or larger and smaller wire, or cloth, or plastic thread configurations as is illustrated in FIG. 5.

Filtering and screening methods illustrated in prior art attempted to improve the propensity of reverse-curved or hooded gutter protection systems illustrated in prior art U.S. Pat. No. 5,557,891 to Albracht, and similar inventions, to trap and hold debris within their open channels. When this has occurred, water has flowed past the clogged open channels and to the ground due to waters tendency to bridge over debris trapped in a concave aperture.

When debris rests on planar surfaces, water will travel beneath, rather than bridge over them, and attempt to travel through any open-air openings or apertures that exist beneath the debris. Filter and screening methods of gutter protection, however, illustrated in prior art have employed woven or knitted or mesh fibers or wires which intrinsically contain numerous joints, which tend to trap and hold debris. Filtering cloths, screens, and meshes are known to trap and hold debris to protect a medium on the other side of the filter. Screens, too, are known to trap and hold debris. When any of these methods of gutter protection have been employed in prior art, such inventions have been known to trap and hold debris reducing the amount of water that is able to enter an underlying rain gutter regardless of the porosity and/or density of the filter medium.

The present invention exhibits no tendency to trap and hold debris, or dirt, or pollen and thereby offers a significant improvement over prior art. The present invention offers an improvement over prior art in that it's filtering membrane 50, offers far fewer under and over knitted or woven or meshed joints for debris to become lodged within. The present invention also offers improvement over prior art in the existence of a strong water channeling action taking place beneath filtering membrane 50 throughout the structure of filter skeleton 43. The water adhesive effects, strong siphoning action, and ultimate breaking of the water adhesion and resulting continued downward flow of water into an underlying rain gutter accomplished by the filter configuration illustrated in FIG. 6 offers improvements not found in prior art. Referring again to FIGS. 5 & 6, the present invention also exhibits an ability to clean or wash smaller particles out of the 100 micron openings existing between the interconnected threads or wires it employs. This ability has not been noted in prior art but, rather, prior art is known to clog with debris or cake over with pollen, leached shingle oil, dirt, and other pollutants and has not exhibited an ability to self-clean, found in the present invention. The present invention is an improvement over prior art that employs insertable, or under-affixed, or recessed filters such as is employed and illustrated in U.S. Pat. No. 5,595,027 to Vail, U.S. Pat. No. 5,956,904 to Gentry, U.S. Pat. No. 5,619,825 to Leroney, U.S. Pat. No. 4,841,686 to Rees, U.S. Pat. No. 6,134,843 to Tregear and similar prior art because these previous filtration attempts are known to either clog, heal over and become water-proof, and/or channel water forward.

Recessed filters beneath a perforated plane such as employed in U.S. Pat. No. 5,595,027 to Vail receive far less water than the present invention due to water adhesion principals that direct water around, rather than through simple perforations. Filtration cloths or membranes resting on top of or sandwiched between screens, perforated planes, or denser filter mediums such as is illustrated in prior art U.S. Pat. No. 4,841,686 to Rees, U.S. Pat. No. 5,595,027 to Vail, U.S. Pat. No. 6,134,843 to Tregear and similar devices are also known to allow water channeling to the front lip of a rain gutter due to the unbroken inter-connected supporting or securing structures beneath or surrounding the filtering membrane and also due to the linear, rather than downward, channeling of water such filtering membranes themselves are known to exhibit in the field.
