Description
RAIN GUTTER COVER ASSEMBLY
RELATED APPLICATIONS
This application is a continuation-in-part of United States Patent Application No.
29/676,184, filed January 9, 2019.
SCOPE OF THE INVENTION
The present invention relates to a rain gutter cover for reducing or preventing the accumulation of leaves, sticks and other debris within a rain gutter trough, and more preferably a rain gutter cover which is configured to engage a forward lip of the gutter trough in an interlocking configuration.
BACKGROUND OF THE INVENTION
The use of eavestrough or rain gutter systems on buildings is well known.
Conventional eavestrough systems typically include an upwardly open U-shaped eavestrough or rain gutter which is positioned along the building eaves to collect and divert rainwater runoff from the building roof to a vertically extending downspout.
The accumulation of leaves, twigs and other debris within the rain gutter presents a maintenance challenge. Such debris not only impedes the flow of collected water longitudinally along the length of the eavestrough, but may further result in blockage of downspouts, interfering with the movement of collected water away from building. The accumulation of water, ice and snow within the gutter trough may result in increased loading, leading to gutter trough deformation, or in extreme cases, failure.
Various rain gutter assemblies have been proposed which incorporate a gutter shield or cover adapted to prevent the collection of leaves and debris within the interior of the gutter trough. United States Patent No. 7,686,008 to Brochu, the contents of which are incorporated herein by reference in its entirety, describes a gutter cover which is formed having a perforated planar central portion, and which includes along one side edge, an upwardly curving portion. The upwardly curving edge portion is configured to fit within a recess formed in a forward upper edge of a K-style gutter trough.

2 rear edge of the gutter cover is formed having an inverted U-shape, sized to fit over the rear wall of the gutter. United States Patent No. 8,322,082 B2 to Neumann, the contents of which are incorporated herein by reference in its entirety, describes a gutter cover front formed as a snap-in hanger attachment. The gutter cover is provided with multiple sieved or perforated horizontal surfaces separated by longitudinal projections.
United States Patent No. 8,695,282 B2 to Glander, the entirety of which is incorporated herein by reference, describes a gutter cover or guard for use with a K-style rain gutter. The gutter cover includes at a forward end, an L-shaped front flange sized for positioning within the recess defined by a lip of the gutter front edge.
The applicant has appreciated that conventional gutter cover arrangements suffer a disadvantage in that the forward edge portion of the gutter cover is typically mounted in an arrangement extending beneath the front gutter lip. This in turn may result in a channel or pocket between the front lip of the gutter and the gutter cover in which leaves, twigs and other debris may collect.
SUMMARY OF THE INVENTION
The present invention seeks to provide a gutter guard or cover for use in combination with an eavestrough or rain gutter, and most preferably a K-style rain gutter, and which is adapted to restrict or minimize the collection of leaves, twigs and other debris within the gutter trough interior, whilst facilitating the shedding of any debris which may be collected thereon outwardly, from the gutter assembly.
Most preferably, the gutter cover is formed with a forward edge portion which is adapted to engage the outer forward lip of a K-style eavestrough or rain gutter in a mechanical interlocking arrangement and which facilitates the securement and positioning of the rain gutter in place against a building facia.
Accordingly, in one aspect the present invention resides in a gutter cover for use with a K-style rain gutter having a generally vertical rear gutter wall, substantially horizontal front gutter-flange portion spaced forwardly from said rear gutter wall, and a gutter lip extending forwardly downward from a rear of the horizontal front gutter-flange

Figures 1 and 3 illustrate best a series of optional cut-outs 68 being formed into the rear portion 50 downwardly through the upper bight 64 and partway through the rear and front webs 60, 62. As shown in Figure 1, the cut outs 68 allow for the positioning of the rain gutter cover 20 over a rain gutter 16 and its mounting against a building facia by way of anchor screws 70 in a conventional manner. In particular, the cut outs 68 allow for the mounting of the rain gutter 16 using conventional rain gutter mounting screws or other hardware 70, without interference or obstruction by the added thickness of the gutter cover 20.
Figure 3 illustrates the central portion 54 as being formed from a single sheet of aluminum with both the rear portion 50 and forward edge portion 52. The central portion 54 preferably includes one or more longitudinally extending reinforcing ribs 72a, 72b.
The reinforcing ribs 72a, 72b are provided with a profile selected to both reduce sagging of the gutter cover 20 in the longitudinal direction, whilst allowing lateral flexure of the central portion 54 to facilitate the positioning of the cover 20 over the rain gutter 16. The reinforcing ribs 72 are further formed with a vertical profile selected so as to substantially not interfere with the deflection or movement of the debris which may accumulate on top of the gutter cover 20 outwardly and off of the gutter assembly 10. Each of the reinforcing ribs 72a, 72b delineate three separate arrays of apertures 74a, 74b, 74c. Each aperture array 74a, 74b, 74c consists of a number of circular apertures 76 formed through the central portion. The apertures 76 preferably have an average diameter selected at between about 1 and 5 mm, preferably about 1 to 2 mm to permit the substantially unimpeded movement of water runoff through the cover 20 and into the rain gutter 16, whilst preventing leaves, twigs and other debris from passing therethrough.
The individual apertures 76 are separated from adjacent apertures within the array 74a, 74b,
Figures 1 and 3 illustrate best a series of optional cut-outs 68 being formed into the rear portion 50 downwardly through the upper bight 64 and partway through the rear and front webs 60, 62. As shown in Figure 1, the cut outs 68 allow for the positioning of the rain gutter cover 20 over a rain gutter 16 and its mounting against a building facia by way of anchor screws 70 in a conventional manner. In particular, the cut outs 68 allow for the mounting of the rain gutter 16 using conventional rain gutter mounting screws or other hardware 70, without interference or obstruction by the added thickness of the gutter cover 20.
Figure 3 illustrates the central portion 54 as being formed from a single sheet of aluminum with both the rear portion 50 and forward edge portion 52. The central portion 54 preferably includes one or more longitudinally extending reinforcing ribs 72a, 72b.
The reinforcing ribs 72a, 72b are provided with a profile selected to both reduce sagging of the gutter cover 20 in the longitudinal direction, whilst allowing lateral flexure of the central portion 54 to facilitate the positioning of the cover 20 over the rain gutter 16. The reinforcing ribs 72 are further formed with a vertical profile selected so as to substantially not interfere with the deflection or movement of the debris which may accumulate on top of the gutter cover 20 outwardly and off of the gutter assembly 10. Each of the reinforcing ribs 72a, 72b delineate three separate arrays of apertures 74a, 74b, 74c. Each aperture array 74a, 74b, 74c consists of a number of circular apertures 76 formed through the central portion. The apertures 76 preferably have an average diameter selected at between about 1 and 5 mm, preferably about 1 to 2 mm to permit the substantially unimpeded movement of water runoff through the cover 20 and into the rain gutter 16, whilst preventing leaves, twigs and other debris from passing therethrough.
The individual apertures 76 are separated from adjacent apertures within the array 74a, 74b,
8 74c by a distance of between about 0.3 and 1.5 cm, and preferably ranging from about 0.4 cm to 1.0 cm.
Figures 4 and 5A show the cover forward edge portion 52 as including an angularly upwardly extending web 80, a covering flange 82, and a hooked anchor edge portion 84. The web 80 is illustrated best in Figure 4 projects upwardly from a front edge of the central portion 54 forwardly at an inclination angle of between about 20 and 80 , and preferably between about 40 and 60 . Figure 4 illustrates the web 80 as preferably including a longitudinally extending array of spaced circular apertures 86 which substantially correspond in size and spacing to apertures 76.
The covering flange 82 projects forwardly from the upper edge of the web 80 in a generally horizontal ( 10 ) orientation. The covering flange 82 has a dimension selected so as to at least partially overlie in juxtaposed contact with at least part of the horizontal flange 40. Most preferably, the webs 62, 80 are provided with dimensions selected to position the central portion 54 generally horizontally, or sloping forwardly downward upto 15 , above the trough bottom 30 in an orientation spaced at between about 0.5 and 3 cm, preferably 1 to 2 cm, and most preferably about 1.5 cm, below the horizontal flange 40 when the cover 20 is secured in a mounted position over the gutter trough 16. The covering flange 82 is shown best in Figure 2 as having a folded double wall construction, having flange layers provided in a flattened, inwardly forward orientation, and wherein the lower flange layer merges with the hooked edge portion 84 along its rearward most edge. Optionally, one or more pilot holes 83 may be formed through the covering flange 82. Preferably, the pilot holes 83 are provided at locations spaced towards each gutter cover 20 end, and are sized to assist in the gutter cover 20 in position over the rain gutter 16. The applicant has appreciated that by positioning the cover flange 82 over the horizontal flange 40, the angular orientation of the web 80 avoids the formation of pockets or recesses between the rain gutter 16 lip portion 34 and the forward portion 52 of the gutter cover 20.
