DETAILED DESCRIPTION OF THE INVENTION

(10) A preferred rain gutter system and hanger is described. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the preferred embodiments of the invention. It is apparent, however, that the preferred embodiments may be practiced without these specific details or with an equivalent arrangement. In other instances, well-known structures and devices are shown in order to avoid unnecessarily obscuring the preferred embodiments of the invention.

(11) It is intended that the gutter system provided herein may be installed as original equipment or as a retrofit application, either as a complete system or utilizing parts of the system disclosed herein. The rain gutter system may additionally be used in conjunction with a rain collection system. In a preferred installation embodiment, conventional fasteners including but not limited to, screws and nails, are advanced through the rear flange of the hangers, the back wall of the gutter and the fascia, and into the underlying rafter tails to support the gutter on a structure. Hangers are preferably installed at spaced-apart intervals along the length of the gutter to adequately support the weight of a loaded gutter. Although any materials may be used in the construction of the system components, preferable materials include those that are lightweight, malleable, corrosion-resistant and paintable, for example aluminum.

(12) The gutter portion of the system is preferably bent/formed from a single planar length of material such that the gutter has a continuous cross-sectional profile, i.e. continuous from the free edge of the lip of the front wall to the free edge of the fold of the back wall. The continuous cross-sectional profile and the addition of an end cap to each end of the length of gutter makes the gutter watertight. The gutter may have any ornamental design, folds and beads. The gutter is preferably bent by machine, such as on-site, to produce the desired profile. The hanger may also be bent and/or formed from a single piece of material such that the flanges and the support surfaces are not separate pieces from the base.

(13) The gutter portion of the system is designed with an overhang or backflow preventing bend to prevent water from traveling upward or horizontally toward the building. Thus, each component is designed to move water away from or laterally with respect to the building to which the system is attached.

(14) Referring now to the drawings, a rain gutter system according to a preferred embodiment of the present invention is illustrated generally at reference numeral 10. Rain gutter system 10 generally includes a gutter 12 having a cross-sectional profile as best shown in FIG. 1, at least one hanger 14 installed within the gutter 12, and conventional fasteners 16 for securing the gutter to a supporting structure, such as an underlying fascia illustrated at reference numeral 18 in FIG. 1. In a specific embodiment, the gutter 12 is ultimately anchored to underlying rafter tails beneath the fascia 18. As shown, roof 20 overhangs gutter 12 such that water run-off from roof 20 is collected within gutter 12 and does not run down fascia 18. Although not shown, gutter 12 is coupled with at least one downspout for draining water from gutter 12 as known to those skilled in the art. Alternatively, gutter 12 may be coupled to a rain collection system.

(15) Gutter 12 has a continuous cross-sectional profile and includes spaced-apart front wall 22 and back wall 24 interconnected through bottom 26 and cooperatively defining water-collecting channel 28 therebetween. Lip 30 extends from front wall 22 in the direction generally toward back wall 24 and functions to capture a forward flange of the hangers 14 beneath it. Drip edge 32 extends beyond front wall 22 in the direction generally away from back wall 24 such that water running off of drip edge 32 is directed away from the front face of front wall 22, preventing “streaking” or “striping” commonly found in conventional gutter designs. Drip edge 32 preferably has a length corresponding to the length of gutter 12 to provide a continuous drip edge along the entire length of gutter 12. In one example, drip edge 32 extends from about 0.5 to about 1 inch beyond front wall 22. As shown, drip edge 32 and a portion of lip 30 are coplanar, and lip 30 further terminates in a bend downward in the direction toward bottom 26. Thus, lip 30 is non-linear and includes approximately a 90-degree bend for capturing the forward flanges of hangers 14 to resist downward and rotational pulling forces on front wall 22.

(16) Gutter 12 further defines a “high-back” provided by back wall 24 extending upward vertically beyond (i.e. “above”) the height of front wall 22. The height of back wall 24 functions to protect underlying fascia 18 from “backflow”, i.e. water flowing against the direction of gravity over the top of back wall 24 and to fascia 18. Back wall 24 further terminates in fold 34 in the direction generally toward front wall 22 and bottom 26. Referring specifically to FIG. 1, free edge 36 of fold 34 is spaced apart from the rear flanges of hangers 14 such that the rear edge of a debris cover can be received and maintained in the provided space. The high back wall gutter profile further allows the receipt of hangers 14 sloped in the direction of drip edge 32. As best shown in FIG. 1, back wall 24 is generally linear and perpendicular to bottom 26, and front wall 22 is non-linear and has a decorative profile that may vary.

(17) Referring to FIGS. 1-4, rain gutter system 10 further includes hanger 14, and preferably a plurality of hangers, spaced-apart and secured within gutter 12. Hangers 14 substantially span the distance between front wall 22 and back wall 24 and prevent their movement, caused by the flow of the water that hits the overlying debris cover, avoiding degradation of the fascia. Thus, the necessity for maintenance of the gutter system is also reduced. Hangers 14 may be installed spaced-apart from bottom 26 to avoid obstructing the flow of water longitudinally along channel 28.

(18) As best shown in FIGS. 2 and 3, hangers 14 are formed from a single piece of material bent to form a complex shape generally including base 38, forward flange 40 and rear flange 42. Forward flange 40 and rear flange 42 are generally L-shaped and include vertical portions 44 extending generally perpendicularly from base 38 and supporting portions 46 oriented substantially perpendicular or at an angle to vertical portions 44 in the direction facing one another. Supporting portion 46, also referred to as “support surface 46”, supports an overlying debris cover and is sloped in the direction toward drip edge 32. Rear flange 42 extends vertically beyond forward flange 40 to provide a sloped profile in the direction of forward flange 40. The vertical portions 44 of the rear flanges 42 may define openings 48 therethrough for receiving conventional fasteners 16 for attaching gutter 12 to the structure. Base 38 includes downward flanges 50 to provide rigidity to hangers 14, thus resisting twisting and bending forces.

(19) Referring to FIGS. 7 and 8, in embodiments, the forward flange 40 and the rear flange 42 may be configured in various sizes and shapes. For example, and as shown in FIGS. 7 and 8, the rear flange 42 may be trapezoidal in shape while the forward flange 40 is rectangular in shape. In such an embodiment, the support surface 46 of the rear flange 42 may include two or more supporting portions 46, while the support surface 46 of the forward flange 40 includes one support portion 46. Also as shown in FIGS. 7 and 8, the rear flange 42 may be wider than the forward flange 40, or vice versa. The various configurations of sizes and shapes of the forward flange 40 and rear flange 42 enhance the ability to customize the integration of the hangers 14 for various use applications. Thus, fewer or larger numbers of hangers 14 may be utilized from one application to the next. For example, the hanger 14 depicted in FIGS. 7 and 8 and having a wider rear flange 42 than the forward flange 40, may in some embodiments, reduce the total number of hangers 14 needed for an application, as opposed to the hangars 14 depicted in FIGS. 2 and 3. As a further example, and as depicted in FIGS. 7 and 8, the two supporting portions 46 of the rear flange 42 may provide additional support, as compared to embodiments that do not have as many supporting portions 46.

(20) Although not shown, in embodiments, each of the openings 48, may also be aligned horizontally or vertically on the vertical portion 44 of the rear flange 42. In yet further embodiments, and as shown in FIGS. 2 and 3, the opening 48 may be aligned underneath the support surface 46 to avoid natural elements (e.g., rain).

(21) As best shown in FIGS. 1 and 4, hangers 14 are installed in gutter 12 such that drip edge 32 and support surfaces 46 of the rear flanges 42 are coplanar and sloped in the direction toward drip edge 32. As best shown in FIGS. 1 and 5, debris cover 52 is cooperatively supported by support surface 46 of rear flange 42 and drip edge 32 in a sloped orientation in the direction of drip edge 32 such that water run-off from roof 20 is directed toward channels 54 defined by debris cover 52. In an exemplary embodiment, debris cover 52 is positioned at an angle of about 23-degrees with respect to horizontal, although alternative angles are envisioned so long as they are adequate for allowing time to collect water while allowing debris to wash over and blow off. Predetermined slopes, such as “4 in 12” or “5 in 12” slopes known to those skilled in the art are also envisioned, or at an incline corresponding to about the incline of overlying roof 20.

(22) Rain gutter system 10 is configured for use with a variety of conventional debris cover designs, preferable designs generally including water-collecting channels covered with a fine mesh or “micromesh”. As shown, channels 54 define openings therethrough for passing water through to channel 28. The width of the mesh portion relative to the surface of debris cover 52 is dependent upon the amount of water desired to pass therethrough, and may be selected based on the distance required to be bridged from fascia 18 to the overlying roof edge. Thus, the mesh portion may range from about 1 to several inches in length.

(23) Referring specifically to FIG. 6, end cap 56 has a perimeter shaped to generally correspond to the shaped defined by the collection of the profiles of front wall 22, bottom 26, back wall 24 and cover 52. End cap 56 preferably sealingly engages gutter 12 and may be secured to gutter 12 by interference fit or using mechanical fasteners. End caps are provided in left- and right-handed versions to close off both ends of gutter 12. End cap 56 may be stamped or bent. End cap 56 may further function to maintain debris cover 52 in place, or alternatively, debris cover 52 may function to help to maintain end cap 56 in place, depending upon which overlaps.

(24) While a gutter system has been described with reference to specific embodiments and examples, it is envisioned that various details of the invention may be changed without departing from the scope of the invention. Furthermore, the foregoing description of the preferred embodiments of the invention and best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation.
