Abstract
Abstract A roof ridge ventilator made of molded plastic parts except for louvered metal sheets closing the open sides of the ventilator, the design providing a low silhouette with a large air flow area through the louvered sheets by sloping the louvered sheets. Stiffness is built into the thin flashing forming part of the ventilator by molding beads into the flashing to inhibit buckling, particularly under extremes of temperature. The ventilator is formed from two molded parts to one of which the louvered sheets which, when fastened together, form a unit which may be installed in multiples to cover any desired length of roof ridge vent opening.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
103 words
A roof ridge ventilator comprising a base sheet of moldable material, said sheet being substantially rectangular in outline and having a central boss extending upwardly from the plane of said sheet, said boss having an opening therethrough, spaced posts formed in the sheet and extending above the central boss, a cover for the opening, said cover being formed of moldable material, a louvered sheet disposed in the space between the cover and base to allow air to pass from the opening in the boss to the exterior of the ventilator, and means on the cover to prevent entry of moisture into said opening.
Claim 2
Dependent Claim
103 words
A roof ridge ventilator comprising a base sheet of moldable material, said sheet being substantially rectangular in outline and having a central boss extending upwardly from the plane of said sheet, said boss having an opening therethrough, spaced posts formed in the sheet and extending above the central boss, a cover for the opening, said cover being formed of moldable material, a louvered sheet disposed in the space between the cover and base to allow air to pass from the opening in the boss to the exterior of the ventilator, and means on the cover to prevent entry of moisture into said opening.
Claim 3
Dependent Claim
26 words
A roof ridge ventilator as described in claim 1, said base having aligned abutments and said louvered sheet being disposed between said cover and said abutments.
Claim 4
Dependent Claim
28 words
A roof ridge ventilator as described in claim 1, said posts having downwardly sloping inwardly extending ledges, and said louvered sheet overlying and being supported by said ledges.
Claim 5
Dependent Claim
44 words
A roof ridge ventilator as described in claim 3, said means on the cover to prevent entry of moisture into said ventilator comprising a peripheral flange, said cover being supported by said posts and said depending flanges extending around said posts and louvered sheets.
Claim 6
Dependent Claim
44 words
A roof ridge ventilator as described in claim 3, said cover being supported by said posts and having a pair of downwardly extending bosses disposed one on either side of said posts in snug relation thereto to locate said cover lengthwise on the posts.
Claim 7
Dependent Claim
32 words
A roof ridge ventilator as described in claim 3, said cover having transverse steps formed at regular inTervals along its length to provide stiffness for said cover, said steps simulating overtapping shingles.
Claim 8
Dependent Claim
49 words
A roof ridge ventilator as described in claim 3, said base having further a central post disposed between said first-mentioned posts, means securing the cover to the top of said central post, and means securing an intermediate portion of said louvered sheet to the side of said central post.
Claim 9
Dependent Claim
21 words
A roof ridge ventilator as described in claim 7, said end and central posts being molded integrally with said base sheet.
Claim 10
Dependent Claim
56 words
A roof ridge ventilator as described in claim 1, said base having formed therein spaced aligned lugs against which said louvered sheet bears, said lugs serving to raise the louvered sheet above the surface of the base to allow drainage of water under said louvered sheet from the interior of the ventilator to the exterior thereof.
Claim 11
Dependent Claim
31 words
A roof ridge ventilator as described in claim 1, said downwardly extending flanges extending around the periphery of the cover and substantially to the level of the opening in said boss.
Claim 12
Dependent Claim
125 words
A roof ridge ventilator as described in claim 9, said posts having downwardly sloping inwardly extruding ledges, said louvered sheet overlying and being supported by said ledges, a central post disposed between said spaced posts, means securing the cover to the tops of said end and central posts, said end and central posts being molded integrally with said base sheet, a pair of downwardly extending bosses on the cover disposed to retain between them in snug relation thereto a post of said base sheet to locate said cover lengthwise with respect to said base sheet, simulated overlapping shingles formed in said cover, and said downwardly extending flanges extending around the periphery of the cover and substantially to the level of the opening in said boss.
