Abstract
Abstract The present invention is a passive diversionary fluid collecting and debris separating apparatus consisting of a surface having an opening and the opening has a first and second downwardly extending fin disposed at an upper and lower edge respectively for channeling fluid for collection, downwardly extending intermediate fins for channeling fluid for collection disposed between and with means connected to said first and second fins and a membrane disposed across the opening for separating debris from the fluid.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
132 words
A passive diversionary fluid and debris separating apparatus for a roof system comprising: a first planar member extending substantially vertically downward with respect to the roof system, said planar member having inner and outer surfaces, with the outer surface defining the initial downward path of travel of fluid and debris from said roof system along said planar member, said planar member including at least one opening formed therein; a fluid permeable planar membrane, said membrane being vertically disposed and covering said opening in said planar member; at least one fin extending inwardly and downwardly from said permeable member, such that a portion of the fluid travelling down said membrane is drawn off by said fin, thereby diverting fluids from the outer surface of said member to the inner surface thereof for collection.
Claim 2
Dependent Claim
132 words
A passive diversionary fluid and debris separating apparatus for a roof system comprising: a first planar member extending substantially vertically downward with respect to the roof system, said planar member having inner and outer surfaces, with the outer surface defining the initial downward path of travel of fluid and debris from said roof system along said planar member, said planar member including at least one opening formed therein; a fluid permeable planar membrane, said membrane being vertically disposed and covering said opening in said planar member; at least one fin extending inwardly and downwardly from said permeable member, such that a portion of the fluid travelling down said membrane is drawn off by said fin, thereby diverting fluids from the outer surface of said member to the inner surface thereof for collection.
Claim 3
Dependent Claim
19 words
An apparatus as recited in claim 1 further including a collection means for capturing fluid diverted by said fin.
Claim 4
Dependent Claim
27 words
An apparatus as recited in claim 2 wherein said planar member forms a portion of an enclosure and wherein said collection means is disposed within said enclosure.
Claim 5
Dependent Claim
44 words
An apparatus as recited in claim 1 wherein a pair of fins are provided, with an upper fin extending inwardly and downwardly from the upper edge of said opening and a lower fin extending inwardly and downwardly from the lower edge of said opening.
Claim 6
Dependent Claim
28 words
An apparatus as recited in claim 4 further including an additional fin extending inwardly and downwardly from said permeable member and disposed between said upper and lower fins.
Claim 7
Dependent Claim
23 words
An apparatus as recited in claim 1 wherein said fluid permeable membrane is removably mounted to the opening formed in said planar member.
