Abstract

A roof vent is made from convoluted filaments. The roof vent includes a center section, a first end section, and a second end section, all made from convoluted filaments. The first and second end sections each include a top layer made from convoluted filaments and a bottom layer made from convoluted filaments. The thickness of the first end section may be substantially the same as a thickness of the center section. A filter may cover the top of the center section, the tops, ends, sides, and bottoms of the first and second end sections, and a portion of a bottom of the center section, leaving a middle portion of the bottom of the center section uncovered by the filter.

First claim

The invention claimed is:

1. A roof vent comprising:
a center section made from a layer of convoluted filaments;
a first end section extending from the center section, wherein the first end section comprises a top layer made from convoluted filaments and a bottom layer made from convoluted filaments; and
a second end section extending from the center section, wherein the second end section comprises a top layer made from convoluted filaments and a bottom layer made from convoluted filaments;
wherein a thickness of the first end section is substantially the same as a thickness of the layer of convoluted filaments of the center section;
wherein a thickness of the second end section is substantially the same as a thickness of the layer of convoluted filaments of the center section;
wherein the bottom layer of the first end section is folded under the top layer of the first end section and the bottom layer of the second end section is folded under the top layer of the second end section; and
wherein the top and bottom layers of the first end section are connected together by a first thin layer of convoluted filament material that acts as a hinge and the top and bottom layers of the second end section are connected together by a second thin layer of convoluted filament material that acts as a hinge.

2. The roof vent of claim 1 wherein a thickness of the top layer of the first end section is one-half the thickness of the layer of convoluted filaments of the center section, a thickness of the bottom layer of the first end section is one-half the thickness of the layer of convoluted filaments of the center section, a thickness of the top layer of the second end section is one-half the thickness of the layer of convoluted filaments of the center section, and a thickness of the bottom layer of the second end section is one-half the thickness of the layer of convoluted filaments of the center section.

3. The roof vent of claim 1 wherein the density of filaments of the first end section is greater than the density of filaments of the layer of convoluted filaments of the center section and the density of filaments of the second end section is greater than the density of filaments of the layer of convoluted filaments of the center section.

4. The roof vent of claim 1 wherein the density of filaments of the first end section is twice the density of filaments of the layer of convoluted filaments of the center section and the density of filaments of the second end section is twice the density of filaments of the layer of convoluted filaments of the center section.

5. The roof vent of claim 1 wherein the top layer of the first end section comprises undulating rows with peaks and valleys and the top layer of the second end section comprises undulating rows with peaks and valleys.

6. The roof vent of claim 1 wherein the bottom layer of the first end section comprises undulating rows with peaks and valleys and the bottom layer of the second end section comprises undulating rows with peaks and valleys.

7. The roof vent of claim 1 wherein the top layer of the first end section comprises undulating rows with peaks and valleys and the bottom layer of the first end section comprises undulating rows with peaks and valleys and the top layer of the second end section comprises undulating rows with peaks and valleys and the bottom layer of the second end section comprises undulating rows with peaks and valleys.

8. The roof vent of claim 7 wherein the roof vent has a length, wherein the undulating rows of peaks and valleys of the top layers extend at a first angle with respect to the length of the roof vent, and the undulating rows of peaks and valleys of the bottom layers extend at a second angle with respect to the length of the roof vent to form a crossing pattern with the undulating rows of peaks and valleys of the top layers.

9. The roof vent of claim 8 wherein said first angle is forty five degrees.

10. The roof vent of claim 1 further comprising a filter that covers a top of the center section, a top of the first end section, a top of the second end section, a side of the first end section, a side of the second end section, a bottom of the first end section, a bottom of the second end section, and a portion of a bottom of the center section, leaving a middle portion of the bottom of the center section uncovered by the filter.

11. The roof vent of claim 10 wherein the first end section includes an end concavity and the end concavity spaces the filter away from a side surface of the first end section and the second end section includes an end concavity and the end concavity spaces the filter away from a side surface of the second end section.

12. The roof vent of claim 1 wherein a portion of the top layer of the first end section is substantially flat and a portion of the top layer of the second end section is substantially flat.

13. The roof vent of claim 12 wherein the substantially flat portion of the first end section is configured to catch the head of a standard roofing nail applied by a standard roofing nail gun.

14. A roof vent comprising:
a center section made from a layer of convoluted filaments;
a first end section extending from the center section, wherein the first end section comprises a top layer made from convoluted filaments and a bottom layer made from convoluted filaments; and
a second end section extending from the center section, wherein the second end section comprises a top layer made from convoluted filaments and a bottom layer made from convoluted filaments;
wherein a thickness of the first end section is substantially the same as a thickness of the layer of convoluted filaments of the center section;
wherein a thickness of the second end section is substantially the same as a thickness of the layer of convoluted filaments of the center section; and
wherein the center section comprises upwardly extending spacer elements with planar base portions and projections extending upward from the planar base portions.

15. The roof vent of claim 14 wherein the density of filaments of the first end section is greater than the density of filaments of the layer of convoluted filaments of the center section and the density of filaments of the second end section is greater than the density of filaments of the layer of convoluted filaments of the center section.

16. The roof vent of claim 14 wherein the top layer of the first end section comprises undulating rows with peaks and valleys and the bottom layer of the first end section comprises undulating rows with peaks and valleys and the top layer of the second end section comprises undulating rows with peaks and valleys and the bottom layer of the second end section comprises undulating rows with peaks and valleys.

17. The roof vent of claim 16 wherein the roof vent has a length, wherein the undulating rows of peaks and valleys of the top layers extend at a first angle with respect to the length of the roof vent, and the undulating rows of peaks and valleys of the bottom layers extend at a second angle with respect to the length of the roof vent to form a crossing pattern with the undulating rows of peaks and valleys of the top layers.

18. A roof vent comprising:
a center section made from a layer of convoluted filaments;
a first end section extending from the center section, wherein the first end section comprises a top layer made from convoluted filaments and a bottom layer made from convoluted filaments;
a second end section extending from the center section, wherein the second end section comprises a top
