Abstract

An in-line surface drain may comprise a cylindrical frame and a plurality of concentric rings coupled to the cylindrical frame. The plurality of concentric rings may be configured to protrude outward from a bottom external surface of the cylindrical frame, and the diameters of the plurality of concentric rings may be different. At least one of the plurality of concentric rings may be configured to detachably accommodate a riser pipe.

Claims (29)

1 . An in-line surface drain, comprising:

a cylindrical frame including a bottom surface, wherein the bottom surface comprises a plurality of steps; and

a plurality of concentric rings configured to protrude outwardly from the bottom surface of the cylindrical frame;

wherein a distance between each of the plurality of concentric rings corresponds to a width of each of the plurality of steps;

wherein a height of each of the plurality of concentric rings is different;

wherein the height of each of the plurality of concentric rings increases from a perimeter of the cylindrical frame to a center of the cylindrical frame; and

wherein each of the plurality of concentric rings comprises at least one slot formed through each of the plurality of concentric rings configured to secure a riser pipe to the in-line surface drain.

2 . The in-line surface drain of claim 1 , wherein the plurality of steps extends downwardly from a perimeter of the cylindrical frame to a center of the cylindrical frame.

3 . The in-line surface drain of claim 1 , further comprising a lip section formed on an external surface of the cylindrical frame.

4 . The in-line surface drain of claim 3 , wherein the lip section comprises at least one anchor point and at least one flange.

5 . The in-line surface drain of claim 4 , wherein the anchor point comprises a hole formed in the lip section.

6 . The in-line surface drain of claim 3 , wherein the lip section comprises a plurality of flanges spaced equidistantly around the cylindrical frame.

7 . The in-line surface drain of claim 1 , wherein at least one of the plurality of concentric rings is configured to detachably accommodate the riser pipe.

8 . The in-line surface drain of claim 1 , wherein the at least one slot comprises a width of approximately one inch.

9 . The in-line surface drain of claim 1 , wherein the at least one slot is tapered at an angle.

10 . The in-line surface drain of claim 9 , wherein a width of a top of the at least one slot is less than a width of a bottom of the at least one slot.

11 . The in-line surface drain of claim 1 , wherein a length of the at least one slot is approximately 3.5 inches.

12 . The in-line surface drain of claim 1 , wherein the plurality of concentric rings are cut from the cylindrical frame.

13 . An in-line surface drain, comprising:

a cylindrical frame including a slanted bottom surface; and

a plurality of concentric rings configured to protrude outwardly from the bottom surface of the cylindrical frame;

wherein a height of each of the plurality of concentric rings is different;

wherein the height of each of the plurality of concentric rings increases from a perimeter of the cylindrical frame to a center of the cylindrical frame; and

wherein each of the plurality of concentric rings comprises at least one slot formed through each of the plurality of concentric rings configured to secure a riser pipe to the in-line surface drain.

14 . The in-line surface drain of claim 13 , wherein the bottom surface slants downwardly from a perimeter of the cylindrical frame to a center of the cylindrical frame.

15 . The in-line surface drain of claim 13 , wherein the at least one slot is tapered at an angle.

16 . The in-line surface drain of claim 13 , wherein a width of a top of the at least one slot is less than a width of a bottom of the at least one slot.

17 . The in-line surface drain of claim 13 , further comprising a lip section formed on an external surface of the cylindrical frame.

18 . The in-line surface drain of claim 13 , wherein the lip section comprises at least one anchor point and at least one flange.
