Abstract
A drain cover assembly. The cover may be used with roof drains or other drains and allow for fluid collection into the drain even with buildup of debris around or on the cover. The cover may have a lower flange or portion with a large area and extending outwardly in an arcuate configuration and having openings for fluid flow. The lower portion may be oriented at a small angle with respect to the horizontal. An upper portion may be connected to the lower portion and may be more vertically-oriented than the lower portion and also extend arcuately and having openings. Locking assemblies may be adjustable to secure the cover to a clamping collar over a drain. The locking assembly may include a base that slidingly engages the collar, and a housing that is secured over the base and to secure the cover to the collar.

A drain cover assembly comprising:
- a cover having an arcuate skirt defining a central axis and extending outward and downward from an upper portion to an outer edge in a first direction that is generally away from the central axis and generally away from the upper portion, the outer edge defining a series of gaps configured to allow fluid to flow through the gaps, wherein the first direction forms an angle A with a portion of the central axis that extends below the skirt, wherein the angle A is greater than or equal to sixty degrees, wherein the skirt forms a plurality of openings extending through the skirt, wherein the cover is configured to be placed over a drain body opening having a maximum width of W, wherein at least a portion of the outer edge of the skirt is located a perpendicular distance R2 from the central axis, wherein R2 is at least twice W, and wherein the skirt defines a notch located between two ribs of the skirt at the outer edge;
- and
- a locking assembly, wherein the notch is configured to receive the locking assembly therein to secure to the cover to a clamping collar that is configured to couple with a mounting surface adjacent a drain.
