Additional features and advantages of the invention will be set forth in the detailed description which follows, and in part will be readily apparent to those skilled in the art from that description or recognized by practicing the invention as described herein.
Various exemplary embodiments are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings in which like reference numerals refer to similar elements and in which: These and other features, aspects and advantages of the present invention are better understood when the following detailed description of the invention is read with reference to the accompanying drawings, in which:
A preferred rain gutter system, including a gutter, hanger and debris cover, and a method of manufacturing the gutter and the debris cover (panel) are 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.
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. For example, in embodiments, the debris panel may be retrofitted to conventional gutter systems. In further embodiments, the debris panel may be retrofitted to conventional gutter systems using the tracking channel. The rain gutter system may additionally be used in conjunction with a rain collection system, such as a water harvesting system. In embodiments, the debris cover provided herein is attached to the gutter system without using any tool or fastening piece, such as screws and nails. The debris cover, also referred to as a panel, may be attached between the support of the hanger and the front lip of the gutter, which are spaced apart to receive the debris cover. In further embodiments, the panel is a micromesh panel. 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, copper, etc.
The gutter portion of the system, the gutter extrusion, 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 along with 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 debris cover portion of the system may also be bent and/or formed, for example, in 10 feet long pieces of material, using a modified or conventional roll forming machine. The debris cover may also be bent and/or formed in a single length of material such that the debris cover has a continuous cross-sectional profile, i.e. continuous from the upper edge, which is supported by the rear support surface of the hanger, to the lower edge, which is supported by the gutter lip and/or by the drip edge of the gutter. In embodiments, the gutter and debris cover are roll formed. In further embodiments, the roll forming process may include multiple roll stands. In yet further embodiments, the rolling process may include eighteen roll stands.
The gutter and debris cover may be manufactured through a roll forming process, which may include bending/forming, for example, eighteen inches of planar material by a roll forming process. The roll forming method may be a modified or conventional roll forming machine that can be carried inside a small truck, or inside a conventional truck widely used by gutter companies when installing gutter systems or parts. In further embodiments, the debris cover is rotary punched to form openings in the debris cover.
In embodiments, the roll forming process of manufacturing the gutter may include a continuous bending operation of planar material through several sets of roll mounted in 13 consecutive stands, while the roll forming process of manufacturing the debris cover may include a continuous bending operation of planar material through several sets of roll mounted in 18 consecutive stands. In further embodiments, the debris cover is rotary punched to form opening in the first stand.
As shown in the drawings, the gutter 111 portion of the system 100 is designed with an overhang or backflow preventing bend, in the form of a hem 115, 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/structure to which the system is attached. The drip edge 113 of the gutter 111 is designed to prevent the external wall of the gutter from becoming dirty by having dirt or mud running from the roof shingles of the front edge of the drip edge, thereby preventing the any staining of the front of the gutter, as conventional gutter systems typically develop over time.
In embodiments, the rain gutter system 100 according to an embodiment of the present invention is illustrated generally at reference numeral 100. Rain gutter system 100 generally includes a gutter 111 having a cross-sectional profile as shown in
Gutter 111 has a continuous cross-sectional profile and includes spaced-apart front wall 112 and back wall 114 interconnected through bottom 116 and cooperatively defining water-collecting channel 119 therebetween. In embodiments, the back wall 114 is vertically higher than the back wall 114. Hangar lip 118 extends from front wall 112 in the direction generally toward the back wall 114 and functions to capture a forward flange of the hangers 131 beneath it. The hangar lip 118 is where the hangar hooks into the gutter extrusion (i.e., gutter, gutter profile). The drip edge 113 extends beyond the front wall 112 in the direction generally away from the back wall 114 and the structure to which the gutter 111 is attached, such that water running off of drip edge 113 is directed away from the front face of front wall 112, preventing “streaking” or “striping” commonly found in conventional gutter designs. Drip edge 113 preferably has a length corresponding to the length of gutter 111 to provide a continuous drip edge along the entire length of gutter 111. In one example, drip edge 113 extends from about 0.5 to about 1 inch beyond front wall 112. As shown, drip edge 113 and a portion of lip 118 are coplanar, and lip 118 further terminates in a bend 117 downward in the direction toward bottom 116. Thus, lip 118 is non-linear and may include approximately a 90-degree bend for capturing the forward flanges of hangers 131 to resist downward and rotational pulling forces on front wall 112. In embodiments, as depicted in
Gutter 111 further defines a “high-back” provided by back wall 114 extending upward vertically beyond (i.e. “above”) the height of front wall 112. The height of back wall 114 functions to protect underlying the fascia of the structure from “backflow,” i.e. water flowing against the direction of gravity over the top of back wall 114 and across the fascia of the structure. Thus, if the gutter overflows with an extremely high volume of water, the high back wall 114 being higher than the front wall 112, the overflow of water would flow over the front wall 112, thus preventing backflow into the structure. Back wall 114 further terminates in a fold with a free edge 110. In embodiments, and as depicted in for example,
In embodiments, the rain gutter system 100 further includes at least one hangar hanger 131, and preferably a plurality of hangers, spaced-apart and secured within gutter 111. Hangers 131 substantially span the distance between front wall 112 and back wall 114 and prevent their movement, caused by the flow of the water that hits the overlying debris cover, avoiding degradation of the fascia of the structure. Thus, the necessity for maintenance of the gutter system is also reduced. Hangers 131 may be installed spaced-apart from bottom 116 to avoid obstructing the flow of water longitudinally along the channel 119 of the gutter 111.
As shown in
Although not shown, in embodiments, each of the openings, may also be aligned horizontally or vertically on the vertical portion of the rear flange. In yet further embodiments, the opening may be aligned underneath the support surface to avoid natural elements (e.g., rain).
As depicted, in some embodiments, the hangers 131 are installed in gutter 111 such that drip edge 113 and support surfaces of the rear flanges are coplanar and sloped in the direction toward drip edge 113. In embodiments, debris cover 101 is cooperatively supported by support surface of rear flange and drip edge 113 in a sloped orientation in the direction of drip edge 113 such that water run-off from roof 121 is directed toward channels 105 defined by debris cover 52. As shown in
Rain gutter system 100 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, elongated channels 105 of the debris cover 101 define openings 107 therethrough for passing water through to channel 119 of the gutter 111. 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 the fascia of the structure and/or the fascia drip edge 123 to the overlying edge of roof 121. Thus, the mesh portion may range from about one to a plurality of inches in length.
In embodiments, an end cap has a perimeter shaped to generally correspond to the shape defined by the collection of the profiles of front wall 112, bottom 116, back wall 114 and debris cover 101. The end cap sealingly engages gutter 111 and may be secured to gutter 111 by interference fit or using mechanical fasteners. End caps are provided in left- and right-handed versions to close off both ends of gutter 111. The end cap may be stamped or bent. The end cap may further function to maintain debris cover 111 in place, or alternatively, debris cover 111 may function to help to maintain the end cap in place, depending upon which overlaps.
In embodiments, the debris cover 111 includes a upper edge to the placed on the rear support surface, at least one opening 107, and a lower edge 73 to be place on the lip 118. The debris cover 101 may also include one or more elongated channel 105, a mesh 110, or a combination thereof. The upper edge and the lower edge may be a two layers edge formed by folding each tip of the edges on top of the each of the corresponding edge of the debris cover. Alternatively, the upper edge and the lower edge may be formed by folding each tip of the edges touching the low part of each of the corresponding edge of the debris cover. It is also envisioned that only one of the edges, i.e. either the upper edge or the lower edge, is folded. Both the upper edge and the lower edge may also be formed with only one layer of material, therefore, not bent or folded.
In embodiments, the debris cover 101 may include several elongated channels 105. In further embodiment, the debris cover 101 includes four elongated channels 105, which may be spaced apart at predetermined distances. In embodiments, the elongated channels may be defined with predetermined widths. Additionally, the surface of the debris cover may be comprised one or more openings 107 which may be spaced apart of each other at predefined distances, and of various shapes and sizes, all of which may be predefined.
The mesh 102 may be secured on top of the surface, preferably a mesh 102. In embodiments, the mesh may be formed with five thousand openings per square inch, to allow the water to efficiently penetrate, while keeping the debris out of the gutter system. In embodiments, the number of openings may be less than five thousand or higher than five thousand.
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.
The present application claims priority to U.S. Provisional Patent Application Ser. No. 62/044,316, filed Aug. 31, 2014, entitled “RAIN GUTTER SYSTEM,” which is incorporated herein by reference in its entirety.
