Abstract

Abstract A vent assembly characterized by a rear member having a perforated rear surface, and a front member having a front surface formed into a number of louvers. The side portions and bottom portions of the rear member are bent into L-shaped flanges which engage the inner dimensions of the front member. The front member has a top portion and side portions which are bent into L-shaped flanges to provide flashing for the assembly. The front member and rear member are permanently attached together to form a single unit, and a number of units can be vertically stacked to provide vent structures of various heights.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 168 words
A unitary, louvered, self-flashing vent assembly comprising: a rear member having a substantially rectangular, planar rear surface, and having opposing top rear and bottom rear portions and opposing side rear portions, wherein said side rear portions and said bottom rear portion are each bent to form an L shaped flange which extends forwardly from said planar rear surface, and wherein said planar rear surface is provided with a plurality of apertures to permit air flow through said rear surface; a front member having a substantially rectangular, planar front surface having opposing top front and bottom front portions and opposing side front portions, wherein said side front portions and said top front portion are each bent to form an L shaped flange which extends rearwardly from said planar front surface to engage said side rear portions and said bottom rear portion, wherein said front surface is provided with a plurality of louvers extending between said side front portions; and means for attaching said front member to said rear member.
Claim 2
Dependent Claim 168 words
A unitary, louvered, self-flashing vent assembly comprising: a rear member having a substantially rectangular, planar rear surface, and having opposing top rear and bottom rear portions and opposing side rear portions, wherein said side rear portions and said bottom rear portion are each bent to form an L shaped flange which extends forwardly from said planar rear surface, and wherein said planar rear surface is provided with a plurality of apertures to permit air flow through said rear surface; a front member having a substantially rectangular, planar front surface having opposing top front and bottom front portions and opposing side front portions, wherein said side front portions and said top front portion are each bent to form an L shaped flange which extends rearwardly from said planar front surface to engage said side rear portions and said bottom rear portion, wherein said front surface is provided with a plurality of louvers extending between said side front portions; and means for attaching said front member to said rear member.
Claim 3
Dependent Claim 42 words
A unitary, louvered, self-flashing vent assembly as recited in claim 1 wherein said plurality of louvers are each substantially rectangular in shape and are attached to said front surface along a lower edge, said plurality of louvers extending towards said rear surface.
Claim 4
Dependent Claim 24 words
A unitary, louvered, self-flashing vent assembly as recited in claim 2 wherein each of said plurality of louvers include a flattened upper edge section.
Claim 5
Dependent Claim 225 words
A unitary, louvered, self-flashing vent structure including at least two louvered, self-flashing vent units, wherein each of said louvered, self-flashing vent units includes: a rear member having a substantially rectangular, planar rear surface, and having opposing top rear and bottom rear portions and opposing side rear portions, wherein said side rear portions and said bottom rear portion are each bent to form an L shaped flange which extends forwardly from said planar rear surface, and wherein said planar rear surface is provided with a plurality of apertures to permit air flow through said rear surface; a front member having a substantially rectangular, planar front surface having opposing top front and bottom front portions and opposing side front portions, wherein said side front portions and said top front portion are each bent to form an L shaped flange which extends rearwardly from said planar front surface to engage said side rear portions and said bottom rear portion, wherein said front surface is provided with a plurality of louvers extending between said side front portions; and means for attaching said front member to said rear member; whereby said bottom rear portion and bottom front portion of a first louvered, self-flashing vent unit overlaps said top rear portion and said top front portion of a second louvered, self-flashing vent unit to form a contiguous louvered, self-flashing vent structure.
Claim 6
Dependent Claim 225 words
A unitary, louvered, self-flashing vent structure including at least two louvered, self-flashing vent units, wherein each of said louvered, self-flashing vent units includes: a rear member having a substantially rectangular, planar rear surface, and having opposing top rear and bottom rear portions and opposing side rear portions, wherein said side rear portions and said bottom rear portion are each bent to form an L shaped flange which extends forwardly from said planar rear surface, and wherein said planar rear surface is provided with a plurality of apertures to permit air flow through said rear surface; a front member having a substantially rectangular, planar front surface having opposing top front and bottom front portions and opposing side front portions, wherein said side front portions and said top front portion are each bent to form an L shaped flange which extends rearwardly from said planar front surface to engage said side rear portions and said bottom rear portion, wherein said front surface is provided with a plurality of louvers extending between said side front portions; and means for attaching said front member to said rear member; whereby said bottom rear portion and bottom front portion of a first louvered, self-flashing vent unit overlaps said top rear portion and said top front portion of a second louvered, self-flashing vent unit to form a contiguous louvered, self-flashing vent structure.
Claim 7
Dependent Claim 42 words
A unitary, louvered, self-flashing vent structure as recited in claim 4 wherein said plurality of louvers are each substantially rectangular in shape and are attached to said front surface along a lower edge, said plurality of louvers extending towards said rear surface.
Claim 8
Dependent Claim 31 words
A unitary, louvered, self-flashing vent structure as recited in claim 5 wherein each of said plurality of louvers include a flattened upper edge section that is attached to said rear surface.
