Abstract
A filtering assembly (10) for protecting an air intake (4) of a structure (2). A flexible screen (12) is mounted so as to cover an air intake opening (4) of the structure (2). The screen (12) may be selectively moved in either of opposite directions so as to be raised or lowered across the intake opening (4). The screen (12) may further be stored at either or both ends of the structure (2).
Claims
AMENDED CLAIMS
[received by the International Bureau on 17 May 1995 (17.05.95); original claims 1-16 replaced by amended claims 1-15 (4 pages)] 1. A filtering assembly for protecting an air intake of a structure, comprising: a flexible screen; means for advancing said flexible screen across an opening of the intake so as to cover the intake, said means comprising at least one pulley mounted to the structure adjacent to the air intake, said pulley receiving at least one pull rope with a first end of said pull rope connecting to said flexible screen and a second end of said pull rope being acted upon to advance said screen; and means for storing said screen attached to the structure.
2. The filtering assembly as described in claim 1, wherein said at least one pulley comprises a pair of pulleys arranged at opposite ends of the air intake and a pair of pull ropes for engaging said pulleys to advance said screen.
3. The filtering assembly as described in claim 2, wherein said flexible screen is of a generally rectangular shape having a top, a bottom, a first side and a second side, and further comprising a rigid elongated member connected to said top of said flexible screen, said pull ropes connecting to said rigid elongated member for advancing said screen across the intake opening.
4. The filtering assembly as described in claim 3, further comprising a first cable and a second cable extending parallel and adjacent to said first side and said second side of said flexible screen and means for slidably connecting said first and second sides of said screen to said first and second cables. 13
5. The filtering assembly as described in claim 4, said means for slidably connecting said first and second sides of said screen to said first and second cables comprising first and second pluralities of O-rings, said O-rings are engaged by said first and second cables and are also engaged within respective first and second pluralities of eyelets formed at the peripheries of said first and second sides.
6. The filtering assembly as described in claim 1, wherein said screen is constructed of a polyester material.
7. The filtering assembly as described in claim 1, wherein said screen is constructed of a wire mesh material.
8. The filtering assembly as described in claim 3, further comprising a second rigid elongated member connected to said bottom of said flexible screen.
9. The filtering assembly as described in claim 1, further comprising a tie-down connected to the structure for attaching said second end of said pull rope.
10. A filtering assembly for protecting an air intake of a structure, comprising: a flexible screen; means for advancing said flexible screen across an opening of the intake so as to cover the intake; and means for storing said screen attached to the structure, said means for storing said screen comprising a container having a bottom and a pair of side walls defining an open interior for receiving said screen and having a lid hingedly connected to one of said side walls. 14
11. The filtering assembly as described in claim 10, further comprising a pair of flexible screens stored within said container.
12. The filtering assembly as described in claim 10, further comprising a plurality of holes formed in said bottom of said container to drain moisture collecting within said container.
13. A filtering assembly for protecting an air intake of a structure, comprising: a flexible screen; means for advancing said flexible screen across an opening of the intake so as to cover the intake; and means for storing said screen attached to the structure, said means for storing said screen comprising a first container positioned along one end of said intake opening and a second container positioned along an opposite end of said intake opening, each of said containers having a bottom and a pair of side walls defining an open interior and having a lid hingedly connecting to one of said side walls.
14. The filtering assembly as described in claim 13, said screen having a first end formed as a first cylindrical roll and a second end formed as a second cylindrical roll, said first cylindrical roll being positioned within said first container and said second cylindrical roll being positioned within said second container so as to cover said intake opening with said screen.
15. The filtering assembly as described in claim 14, further comprising a crank attachable to at least one of said first and second containers, said crank rotating said first and second cylindrical rolls 15
to advance said flexible screen over said intake opening.

STATEMENT UNDER ARTICLE 19
Claim 1 has been rewritten to include the limitations of original claim 2 and now additionally recites the means for advancing the flexible screen across the intake opening as including at least one pulley mounted to the structure adjacent to the air intake. The pulley receives at least one pull rope with a first end of the pull rope connecting to the flexible screen and a second end of the pull rope being acted upon to advance the screen. Claim 2 has been cancelled and claims 3-6 have been rewritten as substitute claims 2-5. Claims 13-16 have also been rewritten as substitute claims 6-9.
Substitute claim 10 incorporates the recitations of original claim 7 and original claim 1 as a new independent claim. Claim 7 recited the means for storing the screen as including a container positioned at the base of the structure and having a bottom and a pair of side walls defining an open interior for receiving the screen and a lid hingedly connected to one of the side walls. Claim 7 has been cancelled and claims 8 and 9 have been rewritten as 17
substitute claims 11 and 12.
Substitute claim 13 incorporates the recitations of original claim 10 and original claim 1 as a further new independent claim. Claim 10 recited the means for storing the screen attached to the structure as including a first container positioned along one end of the intake opening and a second container positioned along an opposite end of the intake opening. Each of the containers includes a bottom and a pair of side walls defining open interiors and a lid hingedly connected to one of each of the pair of side walls. Claim 10 has been cancelled and claims 11 and 12 have been rewritten as substitute claims 14 and 15.
Applicant submits that the amendments to the claims clearly distinguish over the references cited in the International Search Report. None of the cited references show a filtering assembly for an air intake which includes a pulley arrangement for advancing the flexible screen across the intake opening or one or more containers positioned on opposite sides of the intake opening for storing the screen.
Favorable action is respectfully requested in view of the above amendments.
