Abstract

A composite gutter guard is adapted for being positioned at an opening of a longitudinally extending, generally U-shaped gutter used for collecting and distributing rainwater runoff from the roofs of residential homes and other buildings. The gutter guard includes an elongate polymer guard panel defining a plurality of spaced filter openings. The guard panel is adapted to extend laterally across the opening of the gutter and longitudinally along the length of the gutter. A polymer-coated mesh layer overlies the guard panel in an area of the filter openings and cooperates with the guard panel to capture and separate debris from rainwater runoff entering the gutter. A heat weld connects the mesh layer to the guard panel.

Claims

1. A composite gutter guard adapted for being positioned at an opening of a longitudinally extending, generally U-shaped gutter used for collecting and distributing rainwater runoff from the roofs of residential homes and other buildings, said gutter guard comprising:

(a) an elongate polymer guard panel defining a plurality of spaced filter openings, said guard panel being adapted to extend laterally across the opening of the gutter and longitudinally along the length of the gutter;

(b) a polymer-coated mesh layer overlying said guard panel in an area of said filter openings and cooperating with said guard panel to capture and separate debris from rainwater runoff entering the gutter; and

(c) a heat weld connecting said mesh layer to said guard panel.

2. A composite gutter guard according to

claim 1

, and comprising a connecting member for securing said guard panel in position at the opening of the gutter.

3. A composite gutter guard according to

claim 2

, wherein said connecting member comprises a generally C-shaped connecting strip having resilient spaced-apart top and bottom walls adapted for receiving an inwardly-extending flange of the gutter to hold the gutter guard in position during use.

4. A composite gutter guard according to

claim 1

, wherein said mesh layer comprises fiberglass fabric.

5. A composite gutter guard according to

claim 1

, wherein said mesh layer comprises a PVC coating.

6. A composite gutter guard according to

claim 1

, wherein the filter openings in said guard panel are between 0.5 and 1.5 centimeters in diameter.

7. A composite gutter guard according to

claim 1

, wherein said mesh layer includes between 30 and 40 openings per square centimeter.

8. A composite gutter guard according to

claim 1

, wherein said mesh layer extends along the length of said guard panel, and comprises first and second opposing side edges and first and second opposing end edges.

9. A composite gutter guard according to

claim 8

, wherein said heat weld comprises a longitudinal weld line extending continuously along the entire length of said mesh layer from one end edge thereof to the other.

10. A composite gutter guard according to

claim 8

, wherein said heat weld comprises first and second laterally spaced weld lines adjacent respective first and second side edges of said mesh layer and extending continuously along the entire length of said mesh layer from one end edge thereof to the other.

11. A composite gutter guard adapted for being positioned at an opening of a longitudinally extending, generally U-shaped gutter used for collecting and distributing rainwater runoff from the roofs of residential homes and other buildings, said gutter guard comprising:

(a) an elongate polymer guard panel defining a plurality of spaced filter openings, said guard panel being adapted to extend laterally across the opening of the gutter and longitudinally along the length of the gutter;

(b) a polymer-coated fiberglass mesh layer said guard panel in an area of said filter openings and cooperating with said guard panel to capture and separate debris from rainwater runoff entering the gutter, said mesh layer having first and second opposing side edges and first and second opposing end edges;

(c) a longitudinal weld line connecting said mesh layer to said guard panel, and extending continuously from one end edge of said mesh layer to the other; and

(d) a connecting member for securing said guard panel in position at the opening of the gutter.

12. A composite gutter guard according to

claim 11

, wherein said connecting member comprises a generally C-shaped connecting strip having resilient spaced-apart top and bottom walls adapted for receiving an inwardly-extending flange of the gutter to hold the gutter guard in position during use.

13. A composite gutter guard according to

claim 11

, wherein said mesh layer comprises a PVC coating.

14. A composite gutter guard according to

claim 11

wherein the filter openings in said guard panel are between 0.5 and 1.5 centimeters in diameter.

15. A composite gutter guard according to

claim 11

, wherein said mesh layer includes between 30 and 40 openings per square centimeter.

16. A method of forming a composite gutter guard adapted for being positioned at an opening of a longitudinally extending, generally U-shaped gutter used for collecting and distributing rainwater runoff from the roofs of residential homes and other buildings, said method comprising the steps of:

(a) forming a plurality of filter openings in an elongate polymer guard panel, the guard panel being adapted to extend laterally across the opening of the gutter and longitudinally along the length of the gutter;

(b) applying a polymer-coated mesh layer over the guard panel in an area of the filter openings, the mesh layer cooperating with the guard panel to capture and separate debris from rainwater runoff entering the gutter; and

(c) welding the mesh layer to the guard panel.
