The present invention relates to rain gutters for buildings and more particularly to an integrated rain gutter, reverse-curve shield, back flashing and fastening clip system.
Open trough rain gutters collect debris that falls on the roof and washes down with the rain water. Systems to shield the rain gutter from debris include screens over the open trough and reverse-curve shields. The screens have a tendency to clog with small debris, blocking the rain water from entering the rain gutter.
Reverse-curve shields or hoods generally have a sloped planar section that extends over the rain gutter and a coextensive curved section that first curves forwardly and downwardly over the front of the rain gutter and then curves downwardly and inwardly. Rain water, through liquid adhesion principles, follows the curved section to the lower edge of the shield and falls from this lower edge into the rain gutter. Debris washed down by the rain water falls off at the forward extent of the curved section of the shield and drops to the ground.
Known reverse-curve shields can generally be divided into two types. In a first type, the rear of the shield is integrated into the roof, typically by sliding the rear edge of the shield under the lower, forward edge of the roof covering. Reverse-curve shields typically require a certain amount of vertical spacing above the rain gutter. Open top rain gutters are generally mounted as high as possible on the eave, adjacent to the lower edge of the roof. When a reverse-curve shield is added over an open top rain gutter, the required vertical spacing of the shield above the rain gutter can result in the rear edge of the shield being higher than the roof edge. In order to achieve an appropriate geometric configuration of the shield relative to the rain gutter for correct functionality, this first type of reverse-curve shield is typically used when a reverse-curve shield is added over an existing open top rain gutter.
In the second type of reverse-curve shield, the shield mounts only over the rain gutter, independent of the roof. This second type of reverse-curve shield is mounted with specialized fastening clips and typically mounted with the rain gutter as part of an integrated system. When positioned correctly, the shield is located slightly below the roof edge and completely above both the front edge and back edge of the rain gutter. This type of positioning often leaves the back edge of the gutter located well below the existing flashing with the fascia behind the gutter exposed and susceptible to leakage behind the gutter.
Seams or joints in a rain gutter can leak. Seamless rain gutters, with a single seamless section of rain gutter along each straight section of guttered eave, reduce the possibility of leakage and are preferable over rain gutters with joints or seams along straight sections of rain gutter. In many known rain gutters, including many seamless rain gutters, the fasteners that attach the rain gutter to the eave, pierce the rain gutter. Differential thermal expansion between the rain gutter and eave can generate stress on these fasteners, creating a possibility of failure. A mounting system for a rain gutter that allows the rain gutter and shield to independently expand relative to the eave is desirable.
An integrated covered rain gutter system includes a back-flashing, a plurality of fastening clips, a fastener for each fastening clip, an open-top rain gutter, and a reverse-curve shield. The fasteners extend through the base of the fastening clips and the back flashing to anchor the fastening clips and the back flashing to the fascia. The rain gutter and the shield are each mounted on the back flashing and/or the fastening clips, each being anchored vertically and in a fore/aft direction while being allowed to float laterally to prevent stress from thermal expansion. The upper back end of the rain gutter extends behind the lower edge of the back flashing. The upper front end of the rain gutter has an angled face to improve debris shedding. One end of the shield has a barb that is received into a shaped receiving slot on the fastening clips to semi-permanently attach the shield. Means are provided for uniformly locating or aligning the fastening clips relative to the shield.

Describing the specific embodiments herein chosen for illustrating the invention, certain terminology is used which will be recognized as being employed for convenience and having no limiting significance. For example, the terms “front” and “forward” will refer to directions away from the fascia or eave and “back” or “rearward” will refer to directions toward from the fascia or eave on which the rain gutter is installed. With reference to the drawings, this means that “forwardly” is to the right and “rearwardly” is to the left. Further, all of the terminology above-defined includes derivatives of the word specifically mentioned and words of similar import.

The lower portion 34 of the support body 27 has an upwardly opening second receiving slot 41 spaced rearwardly from the rearward surface 39 of the forward end. The second receiving slot 41 has a generally barb shape with a substantially vertical forward surface 43, a lower rearward surface 44 that slants upwardly and rearwardly and an upper rearward surface 45 that slants upwardly and forwardly so that the second receiving slot 41 tapers at the top. The web portion 35 is a vertical wall that extends upwardly from the lower portion 34 to the first receiving slot 29 and forwardly from the base 26 to the second receiving slot 41.

The upper back end 51 of the rain gutter 15 is formed by a forwardly projecting right angle bend at the top of the back wall 47. The upper front end 52 of the rain gutter 15 has a front portion 54 that angles rearwardly and upwardly from the top of the front wall 49, and a rear portion 55 projects downwardly from the back of the front portion 54.
