The present invention relates to rain gutters for buildings and more particularly to an integrated rain gutter, reverse-curve shield, back flashing or back dam, 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.
An alternative integrated covered rain gutter system includes, an open-top rain gutter, a plurality of fastening clips, a fastener for each fastening clip, and a reverse-curve shield with an integrated back dam. The fasteners extend through the base of the fastening clips and the shield to anchor the fastening clips and the shield to the fascia. The rain gutter is mounted on the fastening clips, 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 connects to the lower back edge of the shield with a snap together joint. The upper front end of the rain gutter has an angled face to improve debris shedding. The front 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 gutter and the shield. The back dam prevents leakage behind the rain gutter.

The fastening clip 65 has a base 70 and a support body 71 that extends forwardly from the base 70 to a forward end 72. The fastening clip 65 can be molded plastic. The base 70 is generally vertical and has a rearwardly opening groove 73. The support body 71 has spaced lower, intermediate and upper portions 75, 76 and 77 that project forwardly from the base 70, and web portions 78 that extend between the lower, intermediate and upper portions 75, 76 and 77. The lower portion 75 extends forwardly from the bottom of the base 70 to the forward end 72.
The lower and intermediate portions 75 and 76 converge a selected distance behind the forward end 72. The forward end 72 has a lower surface 80 that curves upwardly and forwardly, and an upper surface 81 that slopes upwardly and rearwardly from the front of the lower surface 80. A rearward surface 82 of the forward end 72 curves, from the back of the upper surface 81, downwardly, then downwardly and forwardly and then downwardly and rearwardly. The lower portion 75 has an upwardly opening receiving slot 84 between the rearward surface 82 and the convergence of the lower and intermediate portions 75 and 76. The intermediate and upper portions 76 and 77 converge intermediate the base 70 and the forward end 72. A fastener aperture 85 extends through the upper portion 76 and the base 70, above the groove 73. The receiving slot 84 has a generally barb shape with a substantially vertical forward surface 87, a lower rearward surface 88 that slants upwardly and rearwardly and an upper rearward surface 89 that slants upwardly and forwardly so that the receiving slot 84 tapers at the top.
The rain gutter 67 has an open top trough shape and includes a back wall 91, a bottom wall 92 and a front wall 93. The back wall 91 is generally planar and vertical. The bottom wall 92 projects forwardly from the bottom of the back wall 91, and is generally planar and horizontal. The front wall 93 projects upwardly and forwardly from the bottom wall 92, and is shaped. The front wall 93 shape shown is first vertical, then transitions into a forwardly convex curve, then transitions into a forwardly concave curve, and then transitions to vertical again. Rain gutters 67 of other shapes can be used.
The upper back end 94 of the rain gutter 67 is formed into a forwardly projecting first joint portion 95, shown as a rearwardly opening first crease 96. The upper front end 98 of the rain gutter 67 has a front portion 99 that angles rearwardly and upwardly from the top of the front wall 93, and a rear portion 100 that projects downwardly from the back of the front portion 99. The upper front end 98 fits over the forward end 72 of the fastening clip 65, so that the rain gutter 67 is slidably mounted to and floats relative to the fastening clip 65. The angled front portion 99 of the upper front end 98 enhances debris shedding.
The shield 68 includes a back dam 102 and a shield portion 103 that extends forwardly from the back dam 102 to a forward end 104. The back dam 102 has a front wall 106 that projects upwardly to a fold 107 and a spaced back wall 108 that extends downwardly from the fold 107. The back wall 108 extends downwardly beyond the bottom of the front wall 106 to a lower back end 109. The lower back end 109 is formed into a forwardly projecting second joint portion 110, shown as a rearwardly opening second crease 111.
The second crease 111 is sized and shaped to snap over the first crease 96 on the gutter 67 to form a snap together joint 112. The joint 112 is sized and shaped to fit into the groove 73 in the base 70 of each fastening clip 65. The joint 112, in combination with the groove 73, is a means for aligning the fastening clips 65 along the back dam 102 and the gutter 67.
The shield portion 103 of the shield 68 has a substantially planar rearward section 114 that slopes forwardly and downwardly from the bottom of the front wall 106 of the back dam 102 and a reverse curve forward section 115 that extends forwardly from the rearward section 114 to the forward end 104. The forward section 115 curves downwardly until the forward section 115 projects rearwardly. The forward end 104 has a barb shape, extending downwardly and rearwardly from the forward section 115 and then folding rearwardly to project upwardly. The forward end 104 is sized to snap into the receiving slot 84 of each fastening clip 65, providing semi-permanent mounting of the reverse-curve shield 68 and preventing the wind from dislodging the reverse-curve shield 68. The forward end 104 of the reverse-curve shield 68 is slidably mounted to and floats relative to the fastening clips 65.
The gutter 67 and shield 68 are snapped together along the joint 112 and the fastening clips 65 are hooked onto the joint 112, prior to lifting the system 63 up to the fascia 32. The plurality of fastening clips 65 are spaced along the joint 112, in similar manner to the spaced fastening clips 13 of system 10 shown in
