Drain extension

Claim 2

A drainage arrangement including drain means, said drain means comprising: a first side wall of predetermined height and length; a second side wall of predetermined height and length disposed opposed to and spaced from said first side wall; said side walls having upper, lower and edge extremeties; surface means interconnecting said first side wall and said second side wall proximate said upper extremeties thereof so as to form therewith a substantially U-shaped channel like member; at least one aperture extending through at least one of said side walls; and louver like means extending inwardly and upwardly from the lower edge of said aperture, into said channel like member, and terminating spaced from said side wall at a level above the level of the upper edge of said aperture.

Claim 3

The drain means of claim 1 wherein support means are disposed within said channel like member to strengthen same and said louver like means.

Claim 4

The drain means of claim 1 wherein said channel like member is open at its ends.

Claim 5

The drain means of claim 1 wherein open bottomed hood means are disposed proximate the outer surface of said aperture.

Claim 6

The drainage arrangement of claim 1 wherein there are a plurality of drain means constructed to be interconnected in a predetermined configuration.

Claim 7

The drainage arrangement of claim 5 wherein said predetermined configuration forms a closed loop which is to be disposed around a septic tank or the like.

Claim 8

The drain means of claim 1 wherein leg members extend outwardly and inwardly from each side member, with inwardly extending portions of said leg members terminating spaced from each other.

Claim 9

The drainage arrangement of claim 1 wherein a plurality of drain means extend at a predetermined angle with respect to the vertical from a substantially circular storm type drain device and wherein said predetermined angle may be 90* for at least some of said drain means.

Claim 10

A drainage arrangement including drain means, said drain means comprising: a first side wall of predetermined height and length; a second side wall of predetermined height and length disposed opposed to and spaced from said first side wall; said side walls having upper, lower and edge extremeties; surface means interconnecting said first side wall and said second side wall proximate said upper extremeties thereof so as to form therewith a substantially U-shaped channel like member; at least one aperture extending through at least one of said side walls; and louver like means extending inwardly and upwardly from the lower edge of said aperture, into said channel like member, and terminating spaced from said side wall at a level above the level of the upper edge of said aperture, a plurality of said U-shaped channel like members being interconnected into a plurality of closed loops disposed in spaced relationship one over the other around a septic tank or the like; fluid conduit means connecting said plurality of closed loops together so that fluid, when disposed therewithin, can flow from a lower loop into the next upper loop; fluid entering means for the lowermost of said loops; and fluid exiting means provided from the uppermost of said loops.

Claim 11

A drainage arrangement including drain means, said drain means comprising: a first side wall of predetermined height and length; a second side wall of predetermined height and length disposed opposed to and spaced from said first side wall; said side walls having upper, lower and edge extremeties; surface means interconnecting said first side wall and said second side wall proximate said upper extremeties thereof so as to form therewith a substantially U-shaped channel like member; at least one aperture extending through at least one of said side walls; and louver like means extending inwardly and upwardly from the lower edge of said aperture, into said channel like member, and terminating spaced from said side wall at a level above the level of the upper edge of said aperture, a plurality of said U-shaped channel like members being interconnected into a plurality of closed loops disposed in spaced relationship one over the other around a septic tank or the like; fluid conduit means connecting said plurality of closed loops together so that fluid, when disposed therewithin, can flow from a lower loop into the next upper loop; fluid entering means for the lowermost of said loops; and fluid exiting means provided from the uppermost of said loops.
