Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 10/920,528, filed Aug. 18, 2004, which is a continuation-in-part of International Application No. PCT/U.S.2004/000545, filed Jan. 12, 2004, which claims the benefit of U.S. Provisional Application No. 60/439,993, filed Jan. 14, 2003.
- Many types of devices are known for preventing rain gutters and down-spouts from becoming clogged with leaves and/or other blown debris.
- One known device is formed of a wire mesh which is inserted into the down spout opening of a rain gutter. The wire mesh prevents leaves or other debris from entering the downspout. While this does not eliminate the need to clean gutters, it does prevent downspouts from becoming plugged which can result in gutters overflowing, freezing or leaking back into the soffit under the roof overhang.
- It has also been known to cover a rain gutter with a mesh or with a solid sheet material leaving only a small gap at the edge of the gutter for water to enter. While this is somewhat effective, it prevents access for cleaning. Although such products greatly reduce the need for cleaning, it is still inevitable that some debris enters the gutter and that periodic cleaning may be necessary.
- It would be desirable to provide a device for preventing downspouts of rain gutters from overflowing that is inexpensively produced, can be easily removed and reinstalled for cleaning, and which will not deteriorate quickly based on exposure to moisture, UV radiation and general atmosphere conditions.
- Briefly stated, the present invention provides a non-woven mesh guard which can be inserted into a downspout opening in a rain gutter in order to prevent debris from entering the downspout. Preferably, the non-woven mesh includes a large free area to allow for the flow of water therethrough while preventing debris from entering the downspout. It is also possible to increase the free area for the flow of water while allowing small pieces of debris to be carried out of the downspout through a plurality of small channels extending through the guard. Anchor pins may be installed in the guard to prevent it from being forced too far down into the downspout opening. Alternatively, the non-woven material may also be formed such that it includes an enlarged top portion which rests in the base of the gutter over the downspout opening while a reduced size portion is inserted into the downspout. It is also possible to form a handle directly in the non-woven mesh material which forms the guard to allow for easier gripping for both installation and removal as well as increased penetration area for draining water therethrough.
- In another aspect of the invention, a debris shedding fence is anchored to the guard and sits in the rain gutter upstream from the downspout opening. The debris shedding fence prevents large debris from reaching the guard.
- In yet another aspect of the invention, the guard includes a piece of non-woven material having a top surface, and a plurality of cross-sections that increase in area toward the top surface. The cross sections are generally complementary to an opening of the downspout. The material is adapted to extend at least partially into the downspout. The increase in area of the cross-sections toward the top surface prevents the material from being over-inserted into the downspout opening.
- The foregoing summary, as well as the following detailed description of the preferred embodiments of the invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there is shown in the drawings embodiments which are presently preferred. It should be understood, however, that the invention is not limited to the precise arrangement shown.
