Description

REFERENCE TO RELATED APPLICATION

This application is a continuation patent application based on U.S. application Ser. No. 12/419,404 filed on Apr. 7, 2009, which is a divisional application based on U.S. application Ser. No. 10/987,930 filed Nov. 12, 2004, now allowed, as U.S. Pat. No. 7,765,742. All of these applications are incorporated by reference in their entirety.

BACKGROUND OF THE INVENTION

The present invention relates generally to rain gutters and more particularly to a gutter cover for preventing debris from falling into such gutters.

Since leaves and other debris frequently clog up rain gutters, some kind of guard or screen which prevents debris from falling into the gutter is desirable. Ideally, a gutter screen directs water into the gutter, prevents debris from entering the gutter, does not itself become clogged with debris and is securely attached to the gutter. The ideal gutter screen requires no maintenance after installation.

Conventional gutter screens are made of hardware cloth, expanded metal or perforated sheet metal, which have holes that often trap debris instead of allowing the debris to slide over the screen. Debris may build up in the holes and cause rainwater to bypass the holes and flow over the gutter instead of into the gutter, or may cause rainwater to build up above the gutter. The debris must thereafter be removed from the screens by hand. Thus, many conventional gutter screens are not maintenance free.

Some prior art screens have holes of smaller diameter to prevent debris from becoming trapped. However, these smaller holes do not allow enough rainwater to flow into the gutter during a heavy rainfall. This is undesirable because the excess water may back up above the gutter or may flow over the screen and gutter. Reference is made to U.S. Pat. Nos. 5,893,240 and 6,151,837, both of which are incorporated by reference herein for all purposes, for additional background information regarding existing gutter screens.

Furthermore, some prior art gutter covers are held in place by fasteners attached to the roof that require holes in the roof along the length of the gutter. Also, some prior art gutter covers may require the use of a bending machine during installation to properly install the cover on the roof.

A need exists for a gutter cover that prevents debris from falling into the gutter and directs water flow into the gutter preventing overflow of the gutter and a gutter cover that is easier to install while maintaining precise spacing between the cover and a front wall of the gutter.

SUMMARY OF THE INVENTION

In general, a first embodiment of this invention is directed to an elongate gutter cover for covering a gutter supported by a gutter hanger. The gutter has front, back and bottom walls and a flange projecting rearward from the front wall and spaced above the bottom wall of the gutter. The gutter cover comprises a central portion, a front portion formed integrally with the central portion and bent downward to contact a front portion of the gutter hanger, and a rear portion formed integrally with the central portion and bent downward at an angle relative to the central portion to contact a rear portion of the gutter hanger. The front portion comprises a top bend, a lower bend below the top bend, an upper leg extending rearward from the top bend to the lower bend, and a lower leg extending forward from the lower bend. The lower leg terminates in a front edge located forward of the upper bend for contact with the front portion of the gutter hanger. Openings are provided in the lower leg located along a length of the gutter cover for the flow of water through the cover into the gutter.

In another embodiment, this invention is directed to an elongate gutter cover for covering a gutter supported by a gutter hanger. The gutter has front, back and bottom walls and a flange projecting rearward from the front wall and spaced above the bottom wall of the gutter. The gutter cover comprises a central portion, a front portion formed integrally with the central portion and bent downward to contact a front portion of the gutter hanger, and a rear portion formed integrally with the central portion and bent downward at an angle relative to the central portion to contact a rear portion of the gutter hanger. The front portion comprises a top bend, a lower bend, and a lower leg extending forward from the lower bend. The lower leg terminates in a front edge located forward of the upper bend for contact with the front portion of the gutter hanger.

In another embodiment, this invention is directed to a gutter system comprising an elongate gutter having front, back and bottom walls and a flange projecting rearward from the front wall and spaced above the bottom wall of the gutter. The system also includes a hanger supporting the gutter. The hanger has a front hanger portion extending up along the front wall of the gutter below the gutter flange, and a rear hanger portion extending up along the back wall of the gutter. The system also includes a gutter cover covering the gutter. The gutter cover comprises a central cover portion, a front cover portion formed integrally with the central cover portion and bent downward for contact with the front hanger portion, and a rear cover portion formed integrally with the central cover portion and bent downward at an angle relative to the central cover portion for contact with the rear hanger portion. The front cover portion comprises a top bend, a lower bend, an upper leg extending rearward from the top bend to the lower bend, and a lower leg extending forward from the lower bend. The lower leg terminates in a front edge located forward of the upper bend for contact with the front hanger portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Now referring to the drawings, a gutter cover of a first embodiment is generally designated 10. The gutter cover is particularly adapted for covering a conventional rain gutter 12 and preventing debris from falling into the gutter. As shown in FIG. 1, the gutter 12 has a front wall 14, a back wall 16 and a bottom wall 18, which combine to form a channel for drainage of rainwater. A conventional flange 22 projects rearward (i.e., toward the building) from the upper edge of the front wall 14. The gutter 12 is suitably attached to a wall 24 of the building by gutter hangers (not shown) to collect rainwater flowing off a downwardly sloping roof 28 of the building. As shown in FIG. 2, a starter row of shingles 29 are attached to the roof 28 to overhang the lower edge margin of the roof, a first (lower) row of shingles 30 are attached to the roof 28 above the starter row of shingles, and a second row of shingles 32 are attached to the roof generally above the lower row. As is discussed in detail below, the gutter cover 10 of this embodiment is held in place between the shingles 30, 32 and is attached to the flange 22 of the gutter 12. The gutter cover 10 receives water from the roof 28 and directs the water across the top surface of the cover and into the gutter 12.

The gutter cover 10 comprises an elongate sheet 34 having a longitudinal axis L1 (FIG. 2) transverse to the direction F1 of water flow down the roof. The sheet 34 includes an upper, shingle mounting portion 38 for reception between the first row shingles 30 and the starter row shingles 29 next to the roof 28, a covering portion 40 adjacent the shingle mounting portion sized to extend over the gutter 12, a bend line 44 separating the mounting portion and the covering portion, and a downwardly extending flange 46 adjacent the covering portion forming a lowermost edge 48 of the cover. The sheet 34 has a surface tension curve 52 for directing water from the covering portion 40 onto the downwardly extending flange 46 and into the gutter 12. In the illustrated embodiment, the cover 10 is attached to the gutter 12 by clips, generally indicated 56, affixed to the cover flange 46 and the gutter flange 22. In one embodiment, the sheet 34 is made of sheet metal (e.g., aluminum) but it is understood that the sheet may include or be made of other materials (e.g., plastic, vinyl, etc.)

As shown in FIGS. 1 and 2, the shingle mounting portion 38 is substantially flat, continuous, unbroken and uninterrupted. The shingle mounting portion 38 is inserted between the first row of shingles 30 and the starter row shingles 29 so that the cover 10 is held in place, at least in part, by the weight of the shingles attached to the roof and the friction force between the shingles and the cover. The shingle mounting portion 38 has a top surface 60 in contact with the shingles 30, a bottom surface 62 in contact with the roof 28, and an upper edge 64 that wedges between the shingles 30 and the roof 28 when installing the cover 10 on the roof. The shingle mounting portion 38 is sized to have a lateral width W1 so that a portion of the top surface of the cover 10 is in contact with the shingles 30 and at least a portion of the bottom surface of the cover is in contact with the starting row shingles 29 next to the roof 28. In one embodiment, the shingle mounting portion 38 may have a width of about 1 inch to 7 inches, in one embodiment about 5 inches.

The bend line 44 is located upstream of the lower edge of the first row of shingles 30 and extends parallel to the longitudinal axis L1 of the cover and comprises a bend 70 in the sheet 34 that separates the shingle mounting portion 38 from the covering portion 40. In the illustrated embodiment, the bend 70 is configured such that bend angle A1 between the covering portion 40 and the shingle mounting portion 38 is about 135 degrees, but it is understood that the angle A1 could vary depending on the slope of the roof 28.

As shown in FIGS. 1A and 2, the bend line 44 comprises a portion of the sheet 34 that has a series of downwardly struck sections 74 equally spaced across the longitudinal length of the cover 10. As shown in FIG. 1A, the downwardly struck sections 74 have openings 76, 78 on both sides to weaken the sheet 34 along the bend line 44 so that the sheet may be easily manipulated when installing the cover 10. The sheet 34 may be manipulated along the bend line 44 so that a correct bend angle A1 may be easily set at the jobsite in accordance with the pitch of the roof 28, and without requiring additional work or machinery at the jobsite to weaken the sheet during installation.

As shown in FIG. 2, the shingles 38, 40 typically have a shingle gap 82 between the adjacent shingles on each row. The bend line 44 is located below the first row of shingles 38 such that the bend angle A1 creates a change in direction of the flow path of water flowing down the shingle gap 82 on the cover. As shown in FIG. 1A, the space between the cover 10 at the bend angle A1 and the first row of shingles 38 creates a pocket 86 that collects water flowing down the shingle gap 82. The pocket 86 causes the flow of water down the shingle gap 82 to collect at the bend angle A1 between the shingle mounting portion 38 and the covering portion 40 of the sheet 34. As water fills the pocket 86, the water is distributed more evenly across the longitudinal length of the cover 10 prior to flowing onto the covering portion 40 of the cover.

In the illustrated embodiment, the covering portion 40 has two spaced apart ribs, generally indicated 92, extending the length of the sheet 34 and a debris separator 96 located between the ribs. As shown in FIG. 1B, each rib 92 includes an upper ramp portion 102, a top wall 104 generally parallel to the covering portion of the sheet 34, and a lower ramp portion 106. The ribs 92 each have a first bend 108 connecting the upper ramp 102 with the covering portion 40 of the sheet 34, a second bend 110 connecting the upper ramp with the top wall 104 of the rib, a third bend 112 connecting the top wall with the lower ramp 106, and a fourth bend 114 connecting the lower ramp with the covering portion of the sheet.

The ribs 92 stiffen the covering portion 40 of the sheet 34 to inhibit flexing or bending of the covering portion. The ribs 92 thereby allow the sheet 34 to be made of a thinner sheet of material. The sheet 34 may be made of material having a thickness no greater than 0.10 inch. In one embodiment, the sheet 34 is made from aluminum having a thickness of about 0.032 inch, but it is understood that other materials and thickness may be used. For example, the sheet 34 may be made of vinyl or plastic and have a thickness of about 0.050 inch.

The ribs 92 distribute the water flow across the longitudinal length of the cover 10 so that the water does not flow in discrete flow paths or streams spaced along the length of the cover. The even distribution of water across the longitudinal length of the cover 10 increases the surface tension holding the water to the cover and prevents the water from flowing over the flange 22 of the gutter 12. The first bend 108 of each ramp 92 creates a change in direction that allows water flowing down the covering portion 40 of the cover 10 to momentarily collect against the upper ramp portion 102 of each rib prior to the water flowing over the top wall 104 of the rib. The water that collects against the upper ramp portion 102 is distributed across the longitudinal length of the cover 10 prior to flowing across the top wall 104 of the ramp 92 and down the lower ramp portion 106. The water distributed across the longitudinal length of the cover 10 has an increased surface tension, as compared to discrete streams, that holds the water to the top surface of the cover.

The debris separator 96 separates debris (e.g., leaves) from the water flowing over the cover 10. As shown in FIG. 1B, the debris separator 96 includes a series of upwardly struck portions, generally indicated 120, of the sheet 34 that each have a ramp 122 and a free end 124 spaced apart from the sheet. In the illustrated embodiment, each of the free ends of the upwardly struck portions form an opening 126 in the sheet 34, (so that portions form “perforated louvers”) but it will be understood that the debris separator 96 may be formed without openings in the sheet without departing from the scope of this invention. Also, the debris separator 96 could comprise downwardly struck sections of the sheet 34 or have ramps 122 that are otherwise shaped (e.g., curved) without departing from the scope of this invention. In the illustrated embodiment the upwardly struck portions 120 are aligned in a row parallel to the longitudinal length of the sheet, but could be otherwise arranged.

As shown in FIG. 2, the debris separator 96 includes unbroken portions 130 of the sheet 34 located between each of the spaced apart upwardly struck portions 120. As water and debris contact the ramp 122 of the upwardly struck portions 120 of the sheet 34, the water tends to flow around the ramp across the unbroken portion of the sheet between the upwardly struck portions of the debris separator 96 with some of the water flowing over the ramp and through the openings. As the water and debris pass over the upwardly struck portions 120, the surface tension holding the debris is broken by air pockets formed between the upwardly struck portions. In some embodiments, the ramp 122 of the debris separator 96 may have a height ranging from about 1/16 inch to ¼ inch, in one embodiment about ⅛ inch, and a width ranging from about ⅛ inch to 1 inch, in one embodiment about ⅜ inch. The broken surface tension between the debris and the water flowing over the cover 10 created by the debris separator 96 causes the debris to separate from the water.

The surface tension curve 52 of the cover 10 directs the water flowing down the covering portion 40 of the cover onto the flange 46 and into the gutter 12. As shown in FIG. 3, the surface tension curve 52 has a varying slope with a first upper curve 134 adjacent the covering portion 40 of the sheet 34 and a second lower curve 136 adjacent the first curve. In the illustrated embodiment, the upper curve 134 has a smaller radius of curvature than the lower curve 136. The lower curve 136 has a larger radius of curvature requiring less surface tension for the water to adhere to the sheet 34 as the water flows over the surface tension curve 52. As such, the water flowing down the sheet 34 adheres to the sheet when flowing over the surface tension curve 52 and does not overflow the gutter 12. Any debris that reaches the surface tension curve 52 will not be adhered to the water so that it will not enter the gutter 12. The momentum of the debris will tend to carry it over the edge of the gutter 12.

In some embodiment, the upper curve 134 may have a radius of curvature ranging from about ⅛ inch to ½ inch, in one embodiment about ⅜ inch, and the lower curve 136 may have a radius of curvature ranging from about ¼ inch to 1 inch, in one embodiment about ⅝ inch. It is understood that instead of two distinct curves 134, 136, the surface tension curve 52 may comprise a continuous curved surface having a varying (e.g., increasing) radius of curvature.

In some embodiments, the surface tension curve 52 may have a height H ranging from about inch to 1¾ inch, in this embodiment about 1 inch. The reduced height of the curve 52 allows the gutter cover 10 to have a lower profile and a more appealing look as compared to prior art covers.

The downwardly extending flange 46 extends from the surface tension curve 52 and forms the lowermost edge 48 of the gutter cover 12. As shown in FIG. 3, the flange 46 has an angled upper portion 140 connected to the lower curve 136 of the surface tension curve 52 and a substantially vertical lower portion 142. In the illustrated embodiment, the lower portion 142 of the flange has holding ribs generally indicated 146 (only one of which is shown in FIG. 3) in the form of longitudinally spaced apart outwardly struck portions 148 that have a free, upper end 150 forming an opening 152 for receiving a portion of the clip 56. The holding ribs 146 of the flange 46 are engageable with the holding clips 56 that secure the cover 10 to the gutter 12. The holding ribs 146 may comprise a bent section without openings for engagement with the clips 56, or any other arrangement to secure the cover 10 to the clips, without departing from the scope of this invention.

Each clip 56 attaches the cover 10 to the gutter 12 and is connected to the downwardly extending flange 46 of the cover on one end and the flange 22 of the gutter 12 on the other end. As shown in FIGS. 3, 3A, and 4A, the clips 56 have a fastening portion, generally indicated 156, for fastening the clip to the gutter 12, a spacer, generally indicated 158, for spacing the cover 10 from the gutter flange 22 by a distance D1 (FIG. 3A), and a receiver, generally indicated 160, for receiving the lower edge 48 of the cover. The distance D1 between the cover 10 and the gutter flange 22 is small enough to prevent debris from falling into the gutter 12 and large enough to allow the water into the gutter so that water does not fall outside the gutter.

The spacer 158 includes three ninety degree bends 166, a vertical section 168, and a horizontal section 170. As seen in FIG. 3, the vertical section 168 of the spacer 158 contacts the flange 22 of the gutter 12 when the clip 56 is installed on the gutter. The vertical section 168 has a height H1 (FIG. 4A) that may range from about 1/16 inch to ¼ inch (in one embodiment about ⅛ inch), and the horizontal section has a length L1 (FIG. 4A) ranging from about 1/16 inch to ¼ inch (in one embodiment about ⅛ inch). The spacer 158 is suitably sized so that the distance D1 ranges from about 1/32 inch to ½ inch, in one embodiment about ⅛ inch. As shown in FIGS. 3 and 4A, the fastener portion 156 includes a substantially flat tab 176 generally parallel to the top surface of the gutter flange 22. The tab 176 extends from the top bend 166 of the spacer 158 and has an opening 178 for receiving a screw 182 or other fastener (e.g., rivet) that attaches the clip 56 to the flange 22 of the gutter 12. The fastener portion 156 has a length L2 (FIG. 4A) suitably ranging from about ¼ inch to ¾ inch, in one embodiment about ⅜ inch. The opening 178 may have a diameter ranging from about 1/16 inch to ¼″ (more preferably about ⅛″) to accommodate various size fasteners 182 for connecting the clip 56 to the gutter flange 22.

The receiver portion 160 of the clip 56 has a generally U-shaped cross-section forming an opening 186 that receives the downwardly extending flange 46 and the lower edge 48 of the cover 10. The receiver 160 has an inner wall 188 and outer wall 190 that are spaced apart and connected by a 180 degree bend 192 at the bottom of the clip 56. The outer wall 190 extends down from the lower bend 192 of the spacer 158 and includes a row of barbs 196 that are struck outwardly from the plane of the wall. The barbs 196 are shaped to engage the holding ribs 146 on the downwardly extending flange 46 of the cover 10. In the embodiment of FIGS. 1-4B, each barb 196 has a pointed free end 198 that engages the holding ribs 146 on the flange 46 of the cover 10. It is understood that the holding ribs 146 may be omitted so that the barbs 196 engage the flat surface of the flange 46 to secure the clips 56 to the cover 10, without departing from the scope of this invention.

Each barb 196 has a length ranging from about 1/16 inch to about ¼ inch (more preferably about ⅛ inch). More or less than three barbs 196 may be provided on each clip 56 and the barbs may be arranged in multiple rows on the receiver 160. It is understood that the barbs 196 may have other shapes and sizes than described herein without departing from the scope of this invention. For example, FIGS. 5A and 5B show an alternative embodiment of the clips 202 having a row of barbs 204 with flat free ends 206.

The inner wall 188 of the receiver 160 has a free end spaced away from the outer wall 190 to form the opening 208 for receiving the downwardly extending flange 46 of the cover 10. The opening 208 suitably has a width W1 (FIG. 3) ranging from about 1/16 inch to ¼ inch (in one embodiment about ⅛ inch) so that the flange 46 engages the barb 196 on one side and the innermost wall 188 of the receiver 160 on the other side.

FIG. 6 shows an alternate embodiment of the invention in which the cover 10 is attached to the gutter by a clip assembly, generally designated 220, including a first clip, generally indicated 222, similar to the clip 56 illustrated in FIGS. 1-4 and a second clip, generally indicated 224, attached to a fastener portion 228 of the first clip. As shown in FIG. 6, the second clip 224 as a generally inverted S-shaped cross-section with an upper wall 230, a lower wall 232, and an intermediate wall 234. An upper 180 degree bend 238 connects the upper wall 230 and intermediate wall 234 and forms a gap 240 therebetween for receiving the fastener portion 228 of the first clip 222. In the illustrated embodiment, the second clip 224 has a barb 244 upwardly struck from the intermediate wall 234 such that the barb has a free end 246 that extends into the gap 240. The barb 244 engages the bottom surface of the fastener portion 228 of the first clip 222 so that the first and second clips 224 are held in secure engagement.

The second clip 224 has a second 180 degree bend 250 that connects the intermediate wall 234 and the lower wall 232 and forms a gap 252 therebetween for receiving the gutter flange 22. In one embodiment, the second clip 224 is made of a flexible material (e.g., aluminum or steel) having a thickness ranging from about 0.01 inch to about 0.10 inch, in one embodiment about 0.024 inch, so that the bottom wall 232 acts as a spring finger that may flex away from the intermediate wall 234 to widen the gap 252 for attachment of the clip to the flange 22 of the gutter 12. The bottom wall 232 of the second clip 224 is biased against the gutter flange 22 so that a holding force against the gutter flange secures the second clip and gutter cover 10 to the gutter 12.

FIG. 7 shows an alternative embodiment of a one-piece holding clip, generally indicated 260, similar to the two-piece clip assembly of FIG. 6, but formed of a single piece of material. As with the previous embodiments, the clip 260 has a fastening portion 262 for attaching the clip to the gutter 12, a spacer 264 for spacing the cover away from the gutter by the proper distance D1, and a receiver portion 266 having a generally U-shaped cross-section for receiving the downwardly extending flange 46 of the cover 10. The fastener portion 262 of the clip 260 is similar to the two-piece design of FIG. 6 in that the clip has a spring biasing member 270 that presses against the gutter 12 to secure the clip to the gutter. The fastening portion 262, receiver 266, and spacer 264 of the clip are formed integrally as a single piece of bent sheet metal.

FIGS. 8 and 9 show a second embodiment of the gutter cover, generally designated 300, that is held in place below the second row of shingles 32 on the roof 28. The gutter cover 300 of this embodiment is similar to the previous embodiment except the shingle mounting portion 302 is extended so that the cover may be mounted beneath the second row of shingles 32 on the roof 28.

The shingle mounting portion 302 includes a continuous sheet that has an upper bend 306 located generally adjacent to an upper free end 308 of the cover 300. As shown in FIG. 9, a downwardly bent portion 312 of the cover 300 contacts the top surface of the first row of shingles 30 to prevent water in the shingle gap 82 of the second row of shingles 32 from flowing under the cover. In one embodiment, the upper bend 306 is spaced away from the free end 308 of the cover 300 by a distance ranging from about ¼ inch to 2 inches, in one embodiment about 1¼″. The bent portion 312 of the cover 300 may form an angle A2 relative to the top surface of the cover ranging from about 15 degrees to 75 degrees, in one embodiment about 30 degrees. This downwardly bent portion 312 may also be used with the embodiment of FIG. 1.

As in the previous embodiments, the cover 300 has a covering portion 316 adjacent the shingle mounting portion 302 sized to extend over the gutter 12, a bend line 318 separating the mounting portion and the covering portion, and a downwardly extending flange 320 adjacent the covering portion forming a lower edge 322 of the cover. The cover 300 has a surface tension curve 326 downstream from the covering portion 316 connecting the covering portion with the flange 320 for directing water from the covering portion onto the downwardly extending flange and into the gutter 12. Some or all of these features may be omitted within the scope of the invention.

In the illustrated embodiment, the cover 300 is attached to the gutter by clips 328 affixed to the downwardly extending flange 320 of the cover and the gutter flange 12. It is understood that the cover 300 of this embodiment may be attached to the gutter 12 by other clips as described herein (e.g., two-piece clip assembly or one-piece clip without fasteners) or other means without departing from the scope of this invention.

FIG. 10 shows an alternative embodiment of a gutter cover, generally indicated 340, which is sized to fit generally between the opposed walls 14, 16 of the gutter 12. The gutter 12 is attached to the outside wall 24 of a building by gutter hangers, one of which is shown and designated 342. The hanger has a back portion 344 bent to hook over the back wall 16 of the gutter 12 and adapted to receive a fastening device, such as a screw or nail (not shown), to secure the gutter to a wall 24 adjacent the roof 28. The hanger 342 has a 90 degree bend 348 that connects the back portion 344 with a central portion 350 of the hanger that extends over the channel formed by the opposed walls 14, 16 of the gutter 12 to support the front wall and reinforce it against inwardly directed pressures, such as are frequently caused by ladders leaning against the gutter. A front portion 352 of the hanger 340 is bent to fit inside the gutter flange 22 to reinforce the front wall 14 against outwardly directed forces, such as caused by someone pulling on the gutter while climbing onto roof.

As shown in FIG. 10, the cover 340 has a generally flat central portion 356, a front edge margin 358 formed integrally with the central portion and bent downwardly to contact the front wall 14 of the gutter 12, and a rear edge margin 360 formed integrally with the central portion and bent downwardly to contact the rear portion 344 of the gutter hanger 342. The front edge margin 358 has an upper bend 364 and a lower bend 366 so that the front edge margin of the cover 340 is bent relative to the central portion 350 to form a channel having a generally V-shaped cross section for receiving the gutter flange 22 therein. The rear edge margin 360 engages the bend 348 in the hanger 342 so that the gutter cover 340 is held in place by the contact of the rear edge margin with the hanger and the front edge margin 358 with the gutter flange 22.

In the embodiment of FIG. 10, the gutter cover 340 comprises a flexible resilient metal, such as an aluminum or steel alloy, and is of integral construction, that is, it is formed from a single continuous section of screening. The gutter cover 340 includes strands of spaced apart wire 368 running perpendicular to edge margins of the cover and strands of spaced apart wire 370 running parallel to the edge margins, the parallel and perpendicular strands being interwoven with one another to form a unitary wire mesh screen having openings therein. The wire mesh screen allows water to enter the gutter 12 through the openings between the strands 368, 370 but prevents debris from passing through the cover 340. A gutter cover made from similar material is disclosed in U.S. Pat. No. 4,907,381, incorporated by reference herein for all purposes. It is understood that the gutter cover 340 may comprise other materials (e.g., a continuous sheet of metal, vinyl, or plastic having machined holes, or wire mesh having smaller or larger openings) that allow water to flow into the gutter 12 and prevent the entry of debris into the gutter or any other material that is resilient so that it can be bent into the configuration shown and held there in tension.

In one embodiment, the gutter cover 340 has a height H2 ranging from about inch to 1½ inch, in one embodiment about 1⅛ inch. The V-shaped cross section of the front channel may have a depth D3 ranging from about inch to 1½ inch, in one embodiment about ¾ inch. The bend 366 of the front edge margin forming the lower channel of the cover 340 may have a radius ranging from about 1/16 inch to ⅝ inch, in one embodiment about ⅛ inch. In one embodiment the angle A3 between the rear edge margin 360 and the central portion 350 of the cover is about 120 degrees, but this angle may vary.

FIG. 11 illustrates an alternative embodiment of the gutter cover 380 substantially similar to the previous embodiment except the cover has an angle A3 between the rear edge margin 382 and the central portion 384 of the cover of about 90 degrees. The rear edge margin 382 of the cover 380 is angled generally parallel to the back wall 16 of the gutter 12 so that the space between the roof 28 and the top of the cover is reduced to decrease the possibility of leaves or other debris becoming caught between the cover and the roof.

FIGS. 12 and 13 illustrate an alternative embodiment of a gutter cover 390 for a gutter 391 supported by a gutter hanger 396 having a central hanger portion 393, a front hanger portion 392 (including a lower bend 392B), and a rear hanger portion 394 (including a lower bend 394B). The gutter cover 390 is held in place between the front portion 392 and the rear hanger 394 of the gutter hanger 396. As shown in FIG. 12, the front hanger portion 392 extends up generally adjacent the front wall of the gutter to a location under the front gutter flange 397, and the rear hanger portion 394 extends up generally adjacent the back wall of the gutter. The gutter cover 390 of this embodiment comprises a substantially continuous (non-perforated) sheet 398 having a generally flat central portion 400, a front (edge margin) portion 402 formed integrally with the central portion and bent downwardly to contact the front portion 392 of the gutter hanger 396, and a rear (edge margin) portion 404 formed integrally with the central portion and bent downwardly to contact the rear portion 394 of the gutter hanger. The gutter cover 390 is held in place above the channel of the gutter 12 by the contact of the front portion 402 of the cover with the front portion 392 of the gutter hanger 396 and the contact of the rear portion 404 of the cover with the rear portion 394 of the gutter hanger. In the embodiment of FIGS. 12 and 13, the cover 390 has an angle A4 between the rear edge margin 404 and the central portion 400 of the cover of about 120 degrees. The rear portion 404 contacts the bend 394B in the gutter hanger 396 so that the cover 390 is held in secure engagement in the gutter 12.

As illustrated in FIGS. 12 and 13, the front portion 402 of the gutter cover 390 comprises a top bend 408 having a first radius of curvature and a lower bend 410 below the top bend having a second radius of curvature larger than the radius of curvature of the top bend. The front portion 402 also includes an upper leg 450 extending downward and rearward from the top bend 408 to the lower bend 410, and a lower leg 452 extending downward and forward from the lower bend. The lower leg 452 terminates in a front edge 454 located forward of the top bend 408 for contact with the front portion 392 of the gutter hanger 396. The top bend 408, upper leg 450, lower bend 410 and lower leg 452 create a generally V-shaped channel for receiving but not contacting the inner surface of the gutter flange 397 to provide a continuous gap 412 between the front portion 402 of the gutter cover and the gutter flange 397 for flow of water through the gap. The front portion 402 of the gutter cover 390 has spaced apart openings 414, 416 located along the longitudinal length of the cover and forward of the top bend 408 for the flow of water through the cover and into the gutter 12. In the illustrated embodiment, the openings 414 are circular and the openings 416 are rectangular shape, but the openings may have other shapes and sizes (e.g., elongate slots) without departing from the scope of this invention. The discrete openings 414, 416 may be replaced by a single elongate opening without departing from the scope of this invention.

In one embodiment, the cover 390 has a height H3 above the gutter hanger 396 ranging from about inch to 1½ inch, in one embodiment about 1⅛ inch. The V-shaped channel of the front portion 402 of the cover 390 may have a depth D4 ranging from about inch to 1¼ inch, in one embodiment about ¾ inch. The radius of curvature of the lower bend 410 may range from about ¼ inch to ⅝ inch, in one embodiment more preferably about ⅜ inch. The circular openings 414 may have a diameter ranging from about ⅛ inch to ¾ inch, in one embodiment about ⅜ inch, and the rectangular openings 416 may have a length and width ranging from about ⅛ inch to 1¼ inch, in one embodiment about ¼ inch by inch. The cover may be made of suitable materials (e.g., metal, vinyl, plastics, etc.) and have a thickness no greater than about 0.1 inches.

FIG. 14 illustrates an alternative embodiment of the gutter cover 430 substantially similar to the previous embodiment except the cover has an angle A4 between the rear edge margin 432 and the central portion 434 of the cover of about 90 degrees. The rear edge margin 432 of the cover 430 is generally parallel to the back wall of the gutter so that the space between the roof 28 and the top of the cover is reduced to decrease the possibility of leaves or other debris becoming caught between the cover and the roof.
