Abstract

A drainage apparatus for fluid runoff comprising one or more grates and a frame having a top portion configured to accommodate the one or more grates. The frame includes a first plurality of plates located within the frame and positioned below the one or more grates. One or more cross members are connected to plates of the first plurality of plates, each of the one or more cross members extends between at least two plates of the first plurality of plates. Each of the one or more grates is secured to a cross member of the one or more cross members.

First claim

What is claimed is:

1 . An elongate or linear drain, comprising:
at least one elongate grate ( 320 ); an elongate frame ( 380 ) including first and second spaced apart sidewalls ( 310 ) defining a channel into which liquid draining through the at least one elongate grate ( 320 ) may flow, the elongate frame ( 380 ) having a top portion capable of supporting the at least one elongate grate ( 320 ); a first plurality of plates disposed within the channel, below the at least one elongate grate ( 320 ), each of the plates of the first plurality of plates extending between and abutting the first and second spaced apart sidewalls ( 310 ); and at least one cross member ( 340 ) spaced apart downwardly from tops of, and extending between and connected to central portions of at least two plates of the first plurality of plates.

2 . The elongate or linear drain of claim 1 , wherein the first and second sidewalls are mirror images of one another.

3 . The elongate or linear drain of claim 1 , wherein each of the first and second sidewalls includes a lower portion, an intermediate portion, and an upper portion, the upper portion corresponding to the top portion of the elongate frame.

4 . The elongate or linear drain of claim 3 , wherein the lower portion of the first sidewall is substantially parallel to the lower portion of the second sidewall and the upper portion of the first sidewall is substantially parallel to the upper portion of the second sidewall.

5 . The elongate or linear drain of claim 4 , wherein a distance between the lower portion of the first sidewall and the lower portion of the second sidewall is less than a distance between the upper portion of the first sidewall and the upper portion of the second sidewall.

6 . The elongate or linear drain of claim 5 , wherein the intermediate portion of each of the first and second sidewalls includes an angled lower section and a flat upper section, each of the at least one grates being configured to rest on the flat upper sections of the first sidewall and the second sidewall and to abut the top portion of the first sidewall and the top portion of the second sidewall.

7 . The elongate or linear drain of claim 3 , wherein each of the plates of the first plurality of plates being tapered such that an upper portion of the plate is wider than a lower portion of the plate, the upper portion of the plate being located closer to the grate than the lower portion of the plate.

8 . The elongate or linear drain claim 3 , wherein the elongate frame further comprises an end plate tapered such that an upper portion of the end plate is wider than a lower portion of the end plate, the upper portion of the end plate being located closer to the at least one elongate grate than the lower portion of the end plate.

9 . The elongate or linear drain of claim 1 , wherein each of the plates of the first plurality of plates has slots to accept the at least one cross member.

10 . The elongate or linear drain of claim 1 , wherein each of the plates of the first plurality of plates has tabs allowing for connection of the plate to the elongate frame.

11 . The elongate or linear drain of claim 10 , wherein each of the plates of the first plurality of plates has slots to accept the at least one cross member.

12 . The elongate or linear drain of claim 1 , wherein the at least one cross member includes interior threading to accept a second end of a fastener, the first end of the fastener being connected to the at least one elongate grate.

13 . The elongate or linear drain of claim 12 , wherein the threading is in the center of the cross member.

14 . The elongate or linear drain of claim 13 , wherein the at least one cross member includes a welded hex nut to secure the fastener to the cross member.

15 . The elongate or linear drain of claim 12 , wherein the at least one cross member engages with slots in at least two of the first plurality of plates.

16 . The elongate or linear drain of claim 15 , wherein the at least one cross member protrudes through the at least two plates of the first plurality of plates.

17 . The elongate or linear drain of claim 12 , wherein the at least one cross member is a substantially horizontal plate having edges protruding down from a top surface of the cross member in a central section of the substantially horizontal plate.

18 . The elongate or linear drain of claim 1 , wherein the at least one cross member spans between only two plates of the first plurality of plates.

19 . The elongate or linear drain of claim 1 , wherein the frame is connected to a drainage pipe at a bottom of the elongate frame.

20 . The elongate or linear drain of claim 19 , wherein the connection of the elongate frame to the drainage pipe is along an entire length of the elongate frame.
