초록 ▼

A cover assembly for a drain comprises a saucer-shaped cover body having a first side configured to face toward a drain opening in a surface and a second side configured to face away from the drain opening. The cover body defines a plurality of flow passages extending between the first side and the second side so as to allow a liquid to pass through the cover body to the drain opening. At least a portion of the second side of the cover body may have a corrugated configuration formed by adjacent grooves and ridges, the grooves and ridges cooperating to facilitate reduction in blockage of the flow passages by debris on the second side of the cover body.

1. A cover assembly for a drain comprising: a saucer-shaped cover body having a first side for facing toward a drain opening in a surface having a drain pipe and a second side for facing away from the drain opening, the saucer-shaped cover body defining a plurality of flow passages extending between said first side and said second side so as to allow a liquid to pass through the cover body to the drain opening, at least a portion of the second side of the saucer-shaped cover body having a corrugated configuration formed by adjacent grooves and ridges, said grooves and ridges cooperating to facilitate reduction in blockage of said flow passages by debris on said second side of said saucer-shaped cover body; andan anchor having a stem and deformable insert structure having a width diameter greater than the internal diameter of said drain pipe, said stem being removably attachable to said saucer-shaped cover body so as to depend from said first side thereof, and said insert structure including a pair of split fork loops at a distal end thereof sized to deform inwardly when inserted into the drain pipe and cause the insert structure to exert pressure on and frictionally engage the internal wall of the drain pipe. 2. The cover assembly of claim 1, wherein at least some of said flow passages are grouped in respective first, second, and third concentric sets of said flow passages. 3. The cover assembly of claim 1, wherein said saucer-shaped cover body comprises first and second annular rings between said first and second and said second and third concentric sets of said flow passages, respectively. 4. The cover assembly of claim 2, further comprising a fourth concentric set of flow passages located radially inside of said third set of concentric flow passages. 5. The cover assembly of claim 2, wherein respective of said flow passages in said first, second, and third set of flow passages are flow slots. 6. The cover assembly of claim 5, wherein each of said flow slots has a generally teardrop configuration which is narrower at a proximal end and wider at a distal end. 7. The cover assembly of claim 1, wherein at least some of said flow passages are formed as radial flow slots. 8. The cover assembly of claim 1, wherein said saucer-shaped cover body further comprises a plurality of support ribs disposed on the first side and extending radially from an apex portion of the cover body. 9. The cover assembly of claim 1, wherein said saucer-shaped cover body defines at least one mounting bore therethrough, said mounting bore receiving a fastener for securing said saucer-shaped cover body to said surface. 10. The cover assembly of claim 1, wherein said saucer-shaped cover body defines a plurality of surface level flow paths to enable surface flow to the drain, said surface level flow paths being spaced apart around a periphery of said cover body. 11. The cover assembly of claim 1, wherein the second side of said saucer-shaped cover body is textured to enhance foot traction thereon. 12. The cover assembly of claim 1, wherein the saucer-shaped cover body has a height less than one-half of its radius. 13. The cover assembly of claim 1, wherein the height of the saucer-shaped cover body is less than one-third the radius of the saucer-shaped cover body. 14. The cover assembly of claim 1, wherein said anchor has a stem portion removably attachable to said saucer-shaped cover body at a proximal end thereof, said insert structure being located at a distal end of said stem portion. 15. The cover assembly of claim 1, wherein said proximal end of said stem portion is insertable into a complementary stem receiver defined on said first side of said saucer-shaped cover body. 16. The cover assembly of claim 15, wherein attachment of said cover body and said anchor is maintained at least in part by press fit. 17. The cover assembly of claim 15, wherein said stem portion of said anchor defines a blind bore in an end thereof alignable with a fastener aperture defined in said saucer-shaped cover body, said anchor being removably attachable to said saucer-shaped cover body by a fastener extending through said fastener aperture into said blind bore. 18. The cover assembly of claim 1, wherein said cover body defines a plurality of spaced apart mounting bores therethrough, said mounting bores receiving a respective fastener for securing said saucer-shaped cover body to said surface. 19. The cover assembly of claim 1, wherein said saucer-shaped cover body defines a plurality of notches to enable surface flow to the drain, said notches being spaced apart around a periphery of said saucer-shaped cover body.
