Next Patent: Rain gutter cover system
[0001] The invention relates to drainage devices and more specifically to drainage devices for eaves troughs or gutters of a roof.
[0002] The invention provides an improved water flow into a rain gutter at points where the water runoff from a roof is heavier than other parts of the roof, while preventing debris (such as leaves and sticks) from entering the gutter and enabling the water to flow more easily into a downspout.
[0003] Rain collecting systems for roofs on houses such as a gutter or an eaves trough have been used as standard equipment for many years. A common problem with standard uncovered rain gutters is that debris, such as leafs and small sticks, collects in such a gutter and this restricts the water from flowing feely into the downspout. Subsequently, overflow of the gutter and plugging of the drainpipe occurs.
[0004] Several prior patents address this problem by installing guards overtop of a rain gutter. Patents for rain gutter run-off controls and debris shields of various types to back at least two decades. The term rain gutter debris shield and runoff control is commonly used in the trade because it claims to eliminated or at least control the amount of debris that is filtered into the drainpipe. Usual ideas are to either design the protecting guards as a one-piece gutter or to add a protecting shield overtop of the gutter. Typical inventions of this type are shown, for example, in the following patents:
U.S. Pat. Nos. 3950951 Zukauskas 1976 4435925 Jeffereys 1984 4757649 Vahldieck 1988 Canadian Patent Numbers: 1328974 Stadnyk 1989 1329459 Sweers 1989 2305159 Neumann & Murdock 2001
[0005] The method of fabricating and attaching the guard, whether it is one piece of an add-on to an existing system is different in every case. They key commonality of these patents however is that each system stretches the length and width of a building or house, not allowing for specific high or low density areas at which points the water drains from a given roof. None of these patents take into account that the flow of water differs, in other words the flow is stronger or weaker at certain points at the end of a roof, when the runoff of peaks such as dormers deliver a river of water to the valley, resulting in a much heavier concentration of water runoff at certain points at the end of a roof (See drawing #1). The effect of these conventional systems, as they are exampled by the aforesaid patents, is that water may run over the guard spilling on the ground rather than being channeled into the eves-trough, creating a spill-over effect.
[0006] Though such aforesaid rain gutter runoff controls and debris shields have considerable popularity and commercial success, there has been a continuing need for improvement.
[0007] Considered broadly, the objective of this invention is to provide a rain gutter debris shield and runoff control that compensates for the amount of water flow over specific types of gutter covers, specifically in those areas at the end of a roof that have significantly more water runoff than others. The secondary objective is to maintain the straining effect of a debris shield so that the effect or objective of this type of gutter cover is not compromised.
[0008] The types of gutter covers that this invention lends itself well to are those that are designed with a solid cover, such as the aforementioned examples of U.S. Pat. No. 4,757,649 Vahldieck and Canadian Patent 2305159 Neumann & Murdock.
[0009] The benefits of this additional “inline valley rain gutter debris shield and runoff control” is that it can be installed into most existing conventional gutter covers and subsequently brings significant cost savings to those consumers who presently own such said gutter-cover systems and wish to correct its shortcomings. This invention is therefore useful to many homeowners.

[0024] Another aspect is that the Inline Valley Piece is esthetically pleasing in contrast to a screen overtop a hole. Therefore it adds to the uniformity of the entire gutter system.
[0025] This preferred design choice is practical and may vary with local conditions such as climate, whether rainfall is heavy or light and the type of debris that may be expected in a give geographic area. It may also vary on different gutter cover designs in length, shape or size, but the principal is unilateral to all applications.
