Abstract
A water distributor for directing water from roofing configurations that form a roof valley to rain gutters is disclosed. The device directs the water traveling down the roof valley into the rain gutters without collecting debris or becoming clogged with leaves or twigs that may interfere with its function.
Description




The invention relates to a water distributor for use with existing rain guttering and roofing. More particularly, the invention relates to a water distributor that is positioned within an inside valley of a roof to direct water in a more uniform manner to the guttering.




BACKGROUND OF THE INVENTION




To eliminate clogging of rain gutters by debris, e.g., leaves, various rain gutter covers have been designed to channel water into a rain gutter, while, at the same time, keeping the debris from entering the rain gutter. One such rain gutter cover is disclosed in U.S. Pat. No. 5,216,851 issued Jun. 8, 1993, herein incorporated by reference. Such rain gutter covers function through water adhesion principles that channel water into the gutter via a plurality of apertures formed in the rain gutter cover. These apertures direct the water into the rain gutter while debris of sufficient size is excluded from entering the rain gutter. Typically, such rain gutter covers are attached between a roofline and a lip of the rain gutter along the entire length of the rain gutter.




However, two portions of a roof may meet at an angle (typically, 90 degrees) to form what is known as an inside corner or inside valley. In principle, water flowing along an inside valley flows onto the top flat portion of a gutter cover following a path to the collector portion where, through principles of surface adhesion, the water is delivered into the rain gutter as the debris carried by the water is jettisoned off of the gutter cover. However, the amount of water flowing from an inside valley may exceed the gutter cover's ability to collect the water, thereby permitting much of the water to overflow the gutter cover and to fall onto the ground resulting in soil erosion, basement leakage and so on.




In an attempt to redirect the rain water from the inside valley to a larger cross-section of gutter covers, vertical deflectors or fence-like devices have been installed on the gutter covers. These fence-like devices extend usually 1½ inches to 3 inches in height and are positioned to interrupt the flow of water before it reaches the gutter covers, thereby diverting the water laterally across the roofing or the horizontal portion of the gutter covers. In essence, the fence-like devices spread the large quantity of water within the inside valley across the roof. Unfortunately, tree debris, twigs, leaves, seeds, and so on accumulate behind the fence-like device, thereby reducing its effectiveness in diverting the rain water. Additionally, debris collecting behind the fence-like device contributes to the deterioration of the roofing material itself. To keep the fence-like device functioning, frequent cleaning is required, which is cumbersome, dangerous and contrary to the intended function of the gutter covers, i.e., keeping the rain gutters maintenance-free.




Therefore, there is a need in the art for a maintenance-free water collection device that functions within an inside valley of the roof without collecting debris.




SUMMARY OF THE INVENTION




The present invention overcomes the disadvantages associated with the prior art. Specifically, the present invention is a water distributor for diverting water from a roof valley into a rain gutter. The device provides the additional advantage of distributing rain water without the device collecting tree debris or becoming clogged with leaves or twigs that may interfere with its function.




One embodiment of the invention comprises a water distributor having a substantially triangular top surface bounded by a first edge, a second edge and a bowed edge. At least one flange is coupled to said first edge or said second edge. The triangular top surface spreads rain water flowing down the roof valley across the top surface, thus distributing the rain water into a rain gutter or a gutter protector.




Another embodiment of the invention comprises a water distributor having a top portion fastened to a first and a second rain gutter which meet beneath a roof valley. The top portion transitions into a vertical section that has at least one aperture. A member is coupled between the vertical section and the respective rain gutters. Rain water entering the water distributor from the roof valley flows onto the member and into the rain gutters.




Another embodiment of the invention comprises an apparatus for directing water from a first roof surface and a second roof surface to a rain gutter. Rain water from the first roof surface is channeled though a leader having a water distributor onto the second roof surface. The water distributor comprises an end for coupling to the leader and a discharge section having a plurality of holes. When rain water passes through the discharge section, a portion of the rain water diverted through the plurality of holes and is distributed across the second roof surface. The distributed water is then collected by the rain gutter generally without overflowing.

DETAILED DESCRIPTION




In accordance with the present invention, a rain water collector is provided which can be installed in existing roof valley configurations in conjunction with existing guttering with or without gutter covers. The present water collector is installed in a manner that does not require fastening devices to be applied to the roofing materials. Hence, it is easily installed generally by a single, unskilled person, and it is easily removed and replaced without damaging the roofing.




Referring to

FIGS. 1-3

, a rain water collector


10


is provided for an inside valley roofing configuration created by two intersecting rooflines


9


. Such intersecting rooflines lead to a configuration of guttering connected at an angle, e.g., a right angle (at point


13


). However, it should be understood that the present water collector can be implemented to accommodate a roofing juncture of any angles.




The water collector


10


has a closed-top portion


1


having a substantially triangular shape and a front portion


50


. In the preferred embodiment, an arcuate front portion


26


is disposed between top portion


1


and front portion


50


. Although the present invention is described below with an arcuate front portion


26


, it should be understood that the present invention can be modified and implemented without the arcuate front portion


26


.




More specifically, the arcuate front portion


26


extends from the top portion into a vertically disposed front portion


50


. The front portion


50


may have a plurality of apertures


7


to direct rain water into a rain gutter. However, if a rain gutter cover


3


is available, vertically disposed front portion


50


can be attached along its bottom edge to a flange


2


of the rain gutter cover


3


. Water collector


10


is constructed of a unitary sheet of constructed metal such as aluminum, aluminum copper alloy, vinyl or other weather resistant plastic. In one illustrative example, the unitary sheet has a length of approximately three (3) feet and a width of between 8 and 20 inches.




Although the present invention is implemented as a unitary sheet, those skilled in the art will realized that the present invention can be implemented having more than one sheet of material. Furthermore, it should be understood that the size (including the angles between the various portions of the water collector) of the present water collector can be adjusted to accommodate the dimension of a particular roof valley. For example, the front portion


50


does not have to form a right angle with respect to the top portion


1


, i.e., these portions are not limited to a horizontal or a vertical configuration. Both portions can be implemented with a slope or pitch with respect to a horizontal or vertical axis.




The top portion


1


is installed such that the front arcuate portion


26


is substantially level (e.g., horizontal) and the top portion


1


is slightly pitched (e.g., 1 to 15 degrees) away from the valley. Such pitch enables water to drain toward the front arcuate portion


26


from an optional rear flap


11


extending from the top portion


1


at an angle that matches the slope of roofing


12


. Rear flap


11


is optional, since it is possible to fabricate the water collector such that the top portion


1


is pitched at an angle that matches the slope of roofing


12


, thereby allowing a portion of the top portion


1


to be directly inserted between the roofing material without the need of a rear flap. However, if the slope of the roofing


12


is particularly sharp, the angled rear flap allows the top portion


1


to be pitched slightly, i.e., having a less inclined slope than the roofing, thereby allowing the rain water to spread out as it travels across the top portion


1


. Therefore, it is generally preferred to incorporate an angled rear flap on the water collector for roofing that has a sharp slope.




To install the water collector


10


, flap


11


is slid between the roofing material such as roof shingles, to cause the water collector


10


to be stationary with respect to the roofing as shown in FIG.


3


. To complete the installation, the bottom portion of vertically disposed front portion


50


is fastened with screws, rivets or clips


14


to the flange


2


of the top flat portion of gutter cover


3


as shown in FIG.


2


. In the event that a gutter cover


3


is not used, the bottom portion of vertically disposed front portion


50


can be attached directly to the rain gutter


6


.




The top portion


1


is also provided with longitudinal ridges or weirs


15


extending approximately ⅛ inches to ½ inches in height for spreading water to the edges of the collector adjacent to the roofing. The purpose of these ridges is to distribute the rain over a greater surface, so that the rain can be directed into the rain gutter at different points. Although a set of ridges


15


is shown in

FIG. 1

, those skilled in the art will realize after considering this specification that ridges of different quantity, shape and size can be employed on different locations on the top portion


1


to achieve the same effect.




For example, in an alternate embodiment, a single ridge


15




a


which is parallel to the front arcuate portion


26


, may extend substantially across the entire width of the water collector. In yet another embodiment, a single ridge


15




b


which starts near the juncture of the rooflines, may extend horizontally and vertically toward the arcuate portion


26


. This ridge


15




b


may have a dome like shape.




The vertical front portion


50


may contain one or more rows of a plurality of apertures


7


, where each aperture contains a flap


16


connected to the top of the aperture, such that the flap


16


extends inwardly toward the rain gutter. These apertures can be formed integrally with the substantially vertical front portion


50


by stamping, piercing, or die cutting the flaps from the front portion and by bending the flaps inwardly.




Due to the principle of surface adhesion, rain traversing over the top of the aperture


7


is drawn into the aperture via the flap


16


. The configuration of these rows of apertures is such that all generally vertical paths of rain flow downwardly across the vertical front portion


50


, are interrupted by at least one of these apertures


7


. The size of these apertures (approximately ½ inch by ¾ inch) should be sufficiently small so as to generally prevent leaves and other debris from entering the rain gutter. Those skilled in the art will realize after considering this specification that apertures of different quantity (including the number of rows), shape and size can be employed to achieve the same water channeling effect.




Referring to

FIG. 1

, the top portion


1


can also be optionally provided with openings


8


for the purpose of directing rain into the rain gutter. Again, the size of these openings (approximately {fraction (1/16)} inch to ¼ inch in diameter) should be sufficiently small so as to generally prevent leaves and other debris from entering the rain gutter. These openings


8


are typically distributed over the surface of top portion


1


to enhance the guidance of rain water into the rain gutter. Since water collector


10


is positioned directly over both a portion of the roofing


12


and the rain gutter


6


, water entering these openings


8


is either directed to the rain gutter


6


directly or to a different portion of the roofing


12


underlying the water collector


10


. In both cases, the desired effect of spreading and directing rain water from the inside valley of a roof into a rain gutter


6


is accomplished.




Those skilled in the art after considering this specification will realize that this water collector


10


can be modified to adopt to valley configurations adjacent to non-connecting guttering at right angles as well as valleys having no roof edge which is adjacent to guttering, or valleys created by a dormer leading to straight guttering. Those skilled in the art after considering this specification will also realize that this water collector


10


can be modified to work with all types of roofing, including but not limited to, wood shingles, metal, slate, tile, and so on. In fact, the present water collector


10


can be used with open unprotected guttering.




Additionally, FIG.


4


through

FIG. 15

illustrate various alternate embodiments of the present invention having a water distributor that is used in conjunction with roof valleys to be installed on new or existing rain guttering. Generally, the water distributor, described in a number of illustrative embodiments detailed below, spreads rain water flowing down a roof valley across the roof surface so that the rain water may be collected by the rain gutter without overflowing. The utility of the water distributor, discussed below, provides a method distributing rain water into the rain gutter without becoming clogged with leaves and other debris. Additionally, the water distributor is easily installed by one unskilled person. Of course, one skilled in the art will be readily able to devise additional variants of the water distributor through use of the teachings disclosed herein.





FIG. 4

is a perspective view of an alternate embodiment of the water distributor invention. In

FIG. 4

, roofing shingles


1


covering a first sloped roof


22


of a building, such as a dwelling house or other structure, are attached to the roof


22


parallel and adjacent to a rain gutter


6


. The rain gutter


6


is optionally fitted with a gutter cover


8


. Roofing shingles


2


covering a second roof


23


are mounted on a gable portion


3


of the dwelling house and are generally perpendicular to the rain gutter


6


. The roofing shingles


1


and


2


meet to form a roof valley


4


along the intersection of the roofs


22


and


23


. Water collected from roofs


22


and


23


flows down the roof valley


4


to the gutter cover


8


mounted on the rain gutter


6


.




In accordance with the present invention, as shown in FIG.


4


through

FIG. 9

, a water distributor


7


is attached by a fastening means, such as screws or rivets, to a top portion


9


of a rain gutter cover


8


affixed to a rain gutter


6


. The water distributor


7


may be alternately attached to a roof valley


4


. Rain water from the roofing shingles


1


and


2


flows down the roof valley


4


onto the top portion


9


of gutter cover


8


along with any tree debris such as blossoms and leaves.




The water distributor


7


has a substantially triangular top surface


39


bounded by a first edge


71


, a second edge


72


and a bowed edge


13


. The first edge


71


and the second edge


72


are generally straight and have an equal length. Alternately, the first edge


71


and the second edge


72


may have unequal lengths. At least one flange is coupled to the first edge


71


or the second edge


72


. Preferably, a flange


10


is present on both the first edge


71


and the second edge


72


. Alternately, the flange


10


may be replaced by one or more tabs. The flange


10


is fastened to the roof or a top


9


of the gutter cover


8


, thus securing the water distributor


7


. Generally, the water distributor


7


is fabricated from one unitary sheet of metal or plastic, although multiple piece construction may be utilized. The reader should note that the flange


10


may be incorporated within the top surface


39


when the top surface


39


is fastened directly to the top


9


of the gutter cover


8


with a screw, nail, rivet or other type of fastener.




The bowed edge


13


is generally curved in form, having a high point


12


that is generally centered along the bowed edge


13


. The two straight edges (


71


and


72


) and the bowed edge


13


generally cause the top surface


39


to be curved (domed shaped).




A rear portion


11


of the top surface


39


is positioned at the intersection of the first and second edges


71


and


72


. The rear portion


11


is attached on top portion


9


of gutter cover


8


at the point of highest concentration of water flowing from the roof valley


4


. The bowed edge


13


is generally (although not necessarily) installed parallel to the rain gutter


6


. As the rain water and other debris flow onto the water distributor


7


, the water and other debris are spread out laterally across water distributor


7


as the flow moves closer to the highest point


12


. The flow of water from the roof valley


4


thus is evenly distributed into a wider flow across the water distributor


7


. The resulting wider flow is more readily accommodated by the gutter cover


8


. By spreading out the volume of water traveling down the roof valley


4


, apertures


14


in the gutter cover


8


are able to effectively collect most of the water while rejecting the debris to the ground. Alternately, the water distributors


7


may be affixed directly to the roof valley


4


.




An optional front portion


15


covers the front of the water distributor


7


and is fastened to the top


9


of the gutter cover


8


with fasteners such as screws or rivets through a flange


16


. The water distributor


7


can be made integrally with the front portion


15


from one unitary sheet of metal or plastic. Alternate forms of plastic fabrication also result in one piece construction. Alternately, the front portion


15


and water distributor


7


can be fabricated from a plurality of separate pieces of metal or plastic (such as aluminum, aluminum copper alloy, coated steel, vinyl or other weather resistant plastic) joined together by methods known to those in the industry. Rather than the front portion


15


being joined at a right angle to the bowed edge


13


of the water distributor


7


, an arcuate surface (not shown) can be used to join them together. Likewise, apertures, (not shown) to collect water can be located in the front portion


15


of water distributor


7


if the water distributor


7


is affixed over the rain gutter


6


.




Another embodiment depicted in FIG.


6


and

FIG. 8

illustrates a water distributor


7


wherein the bowed edge


13


terminates in a lip


40


flared at an angle between 0 and 135 degrees from the top surface


39


of the water distributor


7


. In one embodiment, the lip


40


is flared between 60 and 120 degrees. The lip


40


interrupts the flow of water over the water distributor


7


, directing a greater portion of the flow toward the first and second edges


71


and


72


. Those skilled in the art will recognize that the front portion


15


(of

FIG. 5

) can be extended beyond the bowed edge


13


in a manner to incorporate the lip


40


into a front panel


41


.




Another embodiment of the invention is depicted in

FIG. 10

, FIG.


11


and FIG.


12


. In accordance with the present invention, a water distributor


29


has a top portion


37


fastened to a first rain gutter cover


23


and a second rain gutter cover


24


that are attached to the roof valley


4


. The top portion


37


transitions into a vertical section


38


that has at least one aperture (depicted as a first row of apertures


31


and a second row of apertures


32


). A generally triangular member


34


is coupled between the vertical section


38


and a rain gutter


27


and a rain gutter


28


. The water distributor


29


can be installed in existing roof valley


4


configurations in conjunction with existing rain guttering or gutter covers. The present water distributor


29


additionally can be installed in a manner that does not require fastening devices to be applied to the roofing materials.




Rain water and other debris such as leaves and blossoms flow downward from the two sloped roofs


20


and


21


into the roof valley


4


. The rain water flows down the roof valley


4


and onto the tops of two gutter covers (


23


and


24


) connected together and perpendicular to each other. Water and debris flow onto the top portion


37


of the water distributor


29


leading to a front arcuate portion


30


that transitions to the vertical surface


38


in which there are preferably two rows apertures


31


and


32


. The apertures


31


and


32


allow water to flow through the water distributor


29


while being of sufficiently small size such that the debris can not enter.




A bottom flange


33


coupled to the vertical surface


38


of water distributor


29


is attached to the member


34


. Water entering the apertures or louvers


31


and


32


of the water distributor


29


is directed by the apertures


31


and


32


onto the member


34


. The member


34


is sloped to allow the rain water on the member


34


to flow from the water distributor


29


into the respective gutters


27


and


28


. The member


34


has a front flange


53


in which a front edge of the bottom flange


33


of the water distributor


29


is nested. The rear portion of member


34


is fastened with screws, rivets, clips, adhesives or other fasteners (not shown) to an upper front lip


35


of the rain gutter


27


and


28


. The rear of the member


34


has a drip edge


36


turned downward and into gutter to direct rain water entering the respective gutter


27


and


28


.




Although the present invention is implemented as separate pieces utilizing two rows of apertures (louvers) those skilled in the art will realize that the present invention can be fabricated from one unitary sheet or from individual pieces joined together in various ways known to those skilled in the art. Those skilled in the art will also recognize that gutter covers


23


and


24


can be joined together as one unitary sheet with water distributor


29


integrally built in. Those skilled in the art will additionally be able to substitute other types of water apertures in place of apertures


31


and


32


without deviating from the scope of this invention.





FIG. 13

, FIG.


14


and

FIG. 15

depict alternate embodiments of the invention. The water distributor


47


directs water from a first roof surface


41


across a second roof surface


46


to a rain gutter


42


. Rain water from the first roof surface


41


is channeled though a leader


43


having the water distributor


47


that spreads the rain water exiting the leader


43


across the second roof surface


46


. Distributed water flows down the second roof surface


46


and is collected by the rain gutter


42


.




The water distributor


47


comprises an end


96


connected to a discharge section


44


. The end


96


is configured to mate with conventional leaders


43


.




The discharge section


44


has a plurality of holes


45


through which water flowing through the discharge section


44


is spread across the section roof surface


46


. The discharge section


44


may have varied configurations. For example, the discharge section


44


may comprise an “L” shaped extension


48


. Other examples of configurations for the discharge section


44


include a rectangular extension


49


. The discharge section


44


may additionally be incorporated into a discharge elbow


88


wherein the holes


45


are disposed on the discharge elbow


88


. The extension


48


and


49


may be coupled a conventional elbow


66


or a discharge elbow


88


.




When water from the upper roof


41


is collected in an upper gutter


92


and flows down the leader


43


to the water distributor


47


. The openings


45


of water distributor


47


facilitate distributing the water exiting the leader


43


laterally along roof


46


. Thus, the water stream exiting the leader


43


is consequently not concentrated in high volume vertical stream when reaching the lower gutter


42


. This enables the lower gutter


42


to substantially capture substantially the entire flow of water exiting the leader


43


and distributed by the water distributor


47


. Those skilled in the trade recognize that the quantity of openings, their size and shape can be varied while maintaining the utility of the invention. The lower gutter


42


may have screen or gutter cover similar to that shown in FIG.


4


. Those skilled in the art will readily recognize that the gutter


42


may be covered with any type of cover or screen or may be in the form of a gutter and water collector all in one.




Although various embodiments which incorporate the teachings of the present invention have been shown and described in detail herein, those skilled in the art can readily devise many other varied embodiments that still incorporate these teachings.
