Swimming pool drain
First Claim
1. A drain apparatus for receiving and conducting surface drainage from a site in which the apparatus is installed;
- a body of polymer plastic composition defining an elongated trough adapted for burial below grade at the site of installation; and
a grating of polymer plastic composition adapted to be removably mounted in an interference fit on said trough at grade level of the drainage site and including a plurality of apertures communicating inward with said trough in a drain flow relation therewith.

Abstract
A polymer plastic drain apparatus for the aggregate decking areas of a swimming pool. The drain is comprised of an elongated trough adapted for burial in the aggregate and is formed of a bottom wall and parallel spaced apart upright sidewalls terminating at their upper distal ends in a bifurcated formation defining an intervening space of selected cross-section. Adapted to overlie the trough in a removable mounting relation thereto is an apertured grating having elongated skirts downwardly depending from the longitudinal edges thereof. The skirts are insertable within the intervening spacing of the bifurcated trough formation in a springlike interfit enabling the grating to be removed and replaced as appropriate. Internally of the trough are a plurality of longitudinally spaced transversely arranged sleeves extending between openings in the opposite sidewalls. The sleeves enable reinforcing rods to be implaced and embedded in the decking aggregate when poured and serve to anchor the trough in place within the aggregate when set while inhibiting expansion and contraction of the decking in the areas surrounding the drain.

12. A method of inhibiting expansion and contraction of concrete in areas of the concrete contiguous to a drain embedded in the concrete, comprising the steps of:
-
providing an elongated drain having a body defining a trough to be embedded in the concrete and a grating adapted for removable mounting in an interference fit on said trough; providing sleeves arranged transversely within said drain trough between apertures defined in opposite sidewalls of said trough; placing a reinforcing bar within each of said sleeves of length extending laterally beyond the sidewalls of said trough; securing said trough in position at the site of installation; and pouring the aggregate concrete mix about said secured trough and reinforcing bars. - View Dependent Claims (13, 14)
