Abstract

A gutter screen suitable for the DIY market consists of a tubular sleeve made of metal or plastic mesh. The sleeve is 110 mm in diameter and is pressed by hand into a gutter or drain channel. In roof gutters, it is retained by its deformation between a gutter edge and the overlying roof. The sleeve flattens allowing it to be stored on a reel.

Claims

1. A screen for preventing the entry of debris into a gutter, comprising a tubular sleeve of mesh which at leas substantially fills the gutter.

2. A screen as claimed in claim 1, wherein the sleeve is resilient and deformable such that once constrained at least partially within the gutter remains in position.

3. A screen as clamed in claim 2, comprising a first array of strands aligned in a first direction overlaid by and joined to a second array of strands aligned substantially at 90°

to the first direction.

4. A screen as clamed in claim 2, comprising a first array of strands aligned in a first direction overlaid by and joined to a second array of strands aligned at an acute angle to the first direction.

5. A screen as claimed in claim 3, wherein a first array of mutually parallel strands are aligned in the generally longitudinal direction, the sleeve and a second array of mutually parallel strands arranged circumferentially, said first and second array of strands defining mesh apertures therebetween.

6. A screen as claimed in claim 5, wherein the spacing between the circumferential strands is closer than the spacing between the generally longitudinal strands.

7. A screen as claimed in claim 5, wherein the circumferential strands overlie the generally longitudinal stands.

8. A screen as claimed in claim 5, wherein the generally longitudinal strands are substantially helical.

9. A screen as clamed in claim 5, wherein the spacing in the first direction is 2.5-4.0 mm and 3.5-6.0 mm in the second direction.

10. A screen as claimed in claim 5, wherein the strand size is 1.5-2.5 mm.

11. A screen as claimed in claim 5, wherein the screen is moulded as a continuous sleeve in which apertures are introduced.

12. A screen as claimed in claim 5, wherein the sleeve is deformable to a substantially flat profile in order to permit rolling on a reel.

13. A screen as claimed in claim 1, wherein the sleeve is formed as a flat strip of mesh and the two mutually parallel edges are joined to form a sleeve.

14. A screen as claimed in claim 1, wherein the sleeve is made of HD polyolefin.

15. A screen as claimed in claim 1, wherein the sleeve is made from a strip of expanded metal mesh which is joined to form a sleeve.

16. A screen as claimed in claim 1, wherein the tubular sleeve diameter is 100-130 mm.
