Abstract

A foam insert for a rain gutter for a residential dwelling is provided. The foam insert prevents debris such as leaves, pine needles, gravel, and dirt from entering the rain gutter and permits water to pass through the foam and into the gutter. The foam insert has a channel in the outer side to receive the inwardly projecting lip of a gutter when the foam insert is placed into the gutter. As the foam inserts are installed in the gutter, the lip of the gutter is positioned within the channel. The foam is flexible, which permits the foam insert to be bent and maneuvered into position within the gutter. The foam inserts are formed with a pore size of 14 ppi or below. The foam inserts are inexpensive and may be quickly and easily installed or removed from the gutter by a single individual.

Claims

1. A foam insert for a rain gutter having a rear wall, a front wall and a bottom wall interconnecting said rear wall and said bottom wall with said front wall including an inwardly extending upper lip comprising:

a foam body having a generally triangularly shaped cross-sectional configuration with a angular side extending downwardly and rearwardly from an outer side that defines a void between said angular side and said front and bottom walls of said rain gutter and an upper side that is positioned above said front wall of said rain gutter, said outer side of said foam body being formed with a channel to receive said upper lip of said rain gutter,

wherein said foam body allows the passage of water through said foam insert into said rain gutter while restricting debris from entering into said rain gutter.

2. The foam insert according to claim 1, wherein said foam body further includes an inner side positioned against said rear wall when said foam insert is installed in said rain gutter, said inner side extending from said bottom wall of said rain gutter to said upper side of said foam body.

3. The foam insert according to claim 2, wherein said foam body is formed of an open cell foam material with a pore size less than or equal to 14 ppi.

4. The foam insert according to claim 3, wherein said open cell foam material is a flexible polyurethane foam.

5. The foam insert according to claim 4, wherein said channel has a length and a width substantially equivalent to said upper lip of said rain gutter.

6. A foam insert for a rain gutter having a front wall, a rear wall, a bottom wall, and an upper lip, said foam insert comprising:

a foam body formed of an open cell foam material having a generally triangular cross-section, said foam body including a horizontal upper side, an inner side orthogonal to said upper side, an outer side parallel to and opposing said inner side, and an angular side extending diagonally from said inner side to said outer side,

wherein said outer side contains a channel for receiving said upper lip of said rain gutter.

7. The foam insert of claim 6, further comprising an opposing bottom side parallel to said upper side, said angular side extending diagonally from said bottom side to said outer side.

8. The foam insert of claim 7, wherein said angular side extends downwardly and rearwardly from said outer side to said bottom side to define a void between said angular side and said front wall and said bottom wall of said rain gutter.

9. The foam insert of claim 7, wherein said foam body has a pore size of 14 ppi or below.

10. The foam insert of claim 7, wherein said channel has a length and a width substantially equivalent to said upper lip of said gutter.

11. A combination of a rain gutter and a foam insert therefor comprising:

a rain gutter having a rear wall, a bottom wall, and a front wall, said front wall having an inwardly projecting upper lip, and

a foam body having a triangularly shaped cross-sectional configuration with an angular side extending downwardly and rearwardly from an outer side that defines a void between said angular side and said front and bottom walls of said rain gutter and a top side that is positioned above said front wall of said rain gutter, said outer side of said foam body being formed with a channel to receive said upper lip of said rain gutter,

wherein said foam body permits the passage of water and prevents the passage of leaves and debris into said rain gutter.

12. The combination of claim 11, wherein said foam body further includes an inner side positioned against said rear wall when said foam insert is installed in said rain gutter, said inner side extending from said bottom wall of said rain gutter to said upper side of said foam body.

13. The combination of claim 12, wherein said foam insert is positioned in said rain gutter such that said bottom side of said foam insert rests on said bottom wall of said rain gutter adjacent to said rear wall of said rain gutter, said angular side defining a space within said rain gutter between said front wall and said foam insert for the flow of water along said bottom wall.

14. The combination of claim 13, wherein said foam body further includes a lower side that is located against said bottom wall of said rain gutter when said foam insert is installed therein, said bottom side extending forwardly of said inner side such that said angular side extends from said outer side to said bottom side.

15. The combination of claim 14, wherein said bottom side covers less than half of said bottom wall.

16. The combination of claim 15, wherein said channel has a length and a width substantially equivalent to said upper lip of said gutter.

17. The combination of claim 12, wherein said top side of said foam body is elevated above said front wall of said rain gutter to expose debris thereon to the atmosphere to facilitate drying and removal of said debris.

18. The combination of claim 17, wherein said outer side of said foam body extends downwardly from said upper lip for a distance corresponding to less than half of said front wall of said rain gutter.

19. The combination of claim 13, wherein said foam body is formed of an open cell foam material with a pore size less than or equal to 14 ppi.

20. The combination of claim 19, wherein said open cell foam material is a flexible polyurethane foam.
