Abstract

By incorporating an elongated, generally upstanding, aperture-bearing tube member in the top of a roof drain cover or debris guard, with said elongated pipe extending into the interior of the roof drain assembly, a unique roof drain system is achieved which virtually eliminates clogging of the drain by debris, water, ice or snow buildup. By incorporating the upstanding, elongated pipe member, a safety overflow system is provided which establishes a clog-free flow path for carrying away any water buildup that might otherwise occur from clogged drain covers. Preferably, a generally cylindrically-shaped, elongated tube member is employed which is adjustably mounted to the roof drain cover or debris guard for telescopic, axial adjustable movement relative thereto. In this way, the length of the tube member exposed above the drain cover is adjustable, in order to accommodate alternate roof constructions and drainage problems.

Dependent claims

A roof drain assembly constructed for use on flat roofs and low pitched roofs, said roof drain assembly comprising

A. a base adapted to be mounted substantially co-extensive with the surface of the roof and extending therefrom below the roof surface for receiving water run off from the roof and directing the water run off to a desired location,
B. a strainer cover
a. mounted in overlying covering engagement with the base, and
b. incorporating a plurality of apertures formed therein for enabling water on the roof to flow through said apertures into said base while controlling the entry of unwanted debris into the base, and
C. an elongated, hollow tube member comprising open portal zones at both opposed terminating ends thereof
a. mounted to the cover,
b. extending outwardly from the cover a substantial distance therefrom and terminating at a first open, portal-defining edge,
c. extending inwardly from said cover towards the base and terminating with a second open, portal-defining edge, and
d. incorporating a plurality of apertures formed in the surface of said elongated tube member which extends outwardly from the cover for receiving excess water buildup on the surface of the roof and allowing the flow of said water buildup into said elongated tube member;
whereby excess water existing on the surface of the roof which is unable to flow through said strainer cover is capable of being removed by flowing through said elongated hollow, open-ended-tube member, wherein said elongated hollow tube member is further defined as being axially adjustable relative to said strainer cover to enable said elongated hollow tube member to be mounted to said cover in any desired axially adjustable position relative thereto.

A roof drain assembly constructed for use on flat roofs and low pitched roofs and incorporating a base adapted to be mounted substantially co-extensively with the surface of the roof and extending below the roof surface, a strainer cover mounted in overlying covering engagement with the base and incorporating a plurality of apertures formed therein for allowing water to flow therethrough, while controlling the flow of unwanted debris therethrough, the improvement comprising an elongated hollow tube member incorporating open ends at both terminating ends thereof to assure free flow of water and debris and mounted to the cover with a portion of said elongated hollow tube member extending above said cover, incorporating apertures formed therein for enabling excess water on the roof to be removed by passage through said apertures and said elongated tube member, and being mounted to the cover for axial adjustability relative thereto, thereby enabling said elongated tube member to be positioned in any desired axial length above the cover.
