CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a non-provisional application that claims priority to and the benefit of U.S. Application Ser. No. 61/264,462, filed on Nov. 25, 2009, the entire disclosure of which is hereby incorporated herein by reference.

BACKGROUND

1. Field of the Invention
The present invention relates generally to a roof gutter system, and in particular to a roof gutter system with a removable cover for preventing debris from collecting within a gutter while allowing rainwater to flow into the gutter.
2. Description of the Related Art
Many types of roof gutter systems, and even some with covers to allow rainwater to flow into a gutter and prevent debris from collecting therewithin, are known in the art. However, it is difficult to design a roof gutter system with a cover that provides ease of cleaning and replacement.

SUMMARY

One embodiment provides a gutter system comprising a hanger adapted to be secured with respect to a sidewall of a building underneath an eave of a roof, the hanger having a front portion and a rear portion. When the hanger is secured with respect to the sidewall, the front portion extends frontward from the building sidewall. The front portion is configured to support a front wall of a gutter positioned underneath the eave and has a front flange extending upwardly from the front portion. The rear portion of the hanger extends upwardly from the front portion, and has a rear flange extending downwardly from the rear portion. The gutter system further comprises an elongated cover having an upper rear edge and a lower front edge. The cover has an attached position in which the rear edge of the cover is positioned rearward of the rear flange of the hanger and in which the front edge of the cover is positioned rearward of the front flange of the hanger. In said attached position, the cover is substantially fixed with respect to the hanger and is configured to extend above and along the gutter, to substantially prevent the collection of debris within the gutter. The cover has sufficient flexibility to permit a user to bend the rear edge and the front edge toward one another to remove the cover from the hanger, or to bring the cover to said attached position by positioning the rear edge of the cover rearward of the rear flange of the hanger and simultaneously positioning the front edge of the cover rearward of the front flange of the hanger.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Many gutter systems with various structures for directing rainwater away from a roof of a house or other building structure are known in the art. However, many conventional gutter systems include a gutter with an open side, which can become clogged by leaves or other debris. Gutter systems have been designed with covers, such as screens, to reduce clogging, but these designs can also clog over time. A clogged gutter system prevents a gutter from draining properly, causing overflow, erosion, and potentially damaging the building or home to which the gutter system is attached.
So-called “reverse-curve” gutter cover systems have been designed that allow debris to pass over the gutter, while allowing rainwater to flow from the roof into the gutter. For example, U.S. Pat. No. 5,491,998 discloses a gutter system constructed from a single piece of flat sheet material. However, even reverse-curve gutter systems will eventually clog over time. Additionally, conventional reverse-curve gutter systems are difficult to clean and require replacement of the entire gutter system when a clog occurs.
Embodiments of the present invention provide a simple, effective reverse-curve gutter cover system that allows rainwater to flow into a gutter, while preventing material from doing the same. Some embodiments provide a cover that can be easily removed and/or replaced.
FIGS. 1A and 1B illustrate an isometric and side cross-sectional view, respectively, of an embodiment of a gutter system 10 comprising a hanger 20 and a cover 30, adapted to be used with a gutter 40.

In an embodiment, an outwardly facing surface of upper portion 31 faces at least partially upwardly, and an outwardly facing surface of lower portion 32 faces at least partially downwardly, wherein downwardly and upwardly are defined relative to the building or structure onto which the gutter system 10 is to be mounted. In an embodiment, intermediate portion 35 can include an outwardly facing surface that includes an upper facing section 35 a and a downward facing section 35 a. In this way, intermediate portion 35 transitions from an upwardly facing direction to a downwardly facing direction, and connects an upwardly facing outer surface of upper portion 31 with a downwardly facing outer surface of lower portion 32. In a preferred embodiment, intermediate portion 35 is curved, to form a substantially arcuate “nose,” or a “reverse curve” section that connects an upwardly facing outer surface of upper portion 31 with a downwardly facing outer surface of lower portion 32.
In operation, rainwater flows off of and away from the roof 80 (FIG. 1C), and onto the outer surface 30 a of cover 30. The rainwater flows along the upper portion 31 of cover 30, away from the roof 80 and the building structure 60, and towards intermediate portion 35. The rainwater flows along the upward facing surface of intermediate portion 35, and continues onto the downward facing surface of intermediate portion 35, where surface tension holds the rainwater to the cover 30 as the rainwater flows downward. The fluid reverses direction, and continues towards the sidewall 50 of the building 60, and along the downward facing surface of lower portion 32. The rainwater continues through a gap or opening 36 between cover 30 and front wall 41 of gutter 40, into the channel 46 of gutter 40, and is drained away from the building, as is known in the art. The material of the cover 30, the size and extension of intermediate portion 35 (relative to the front wall 41 and lip 47 of gutter 40), and the size of opening 36 can be selected such that debris does not flow along the downward facing surface of lower portion 32, and into channel 46, and instead, flows over and away from the outer edge of gutter system 10, without entering channel 46.
