Abstract
A shower drain having a tapered body and arcuate keepers circumferentially disposed around the body and capable of being drawn up the tapered body from a lower position to a higher position to engage the underside of a shower drain floor and hold the drain in place. When the keepers are in the lower position the drain readily fits through the floor drain opening. The keepers are drawn up the body by turning bolts extending through openings in the drain flange. The keepers extend substantially the full circumference of the drain body to provide maximum seating area against the underside of a shower floor.
Claims12
A drain for installation in a floor, the floor having a top side and an underside, the drain comprising:
- a hollow body having a downstream portion, an upstream portion and a flange, the downstream portion configured to fit onto a drainpipe located underneath the floor, the upstream portion having an upper end and an outer surface that tapers outward in the upstream direction, the flange extending peripherally outward from the upper end of the upstream portion for seating against the top side of the floor;
- adjusting means extending downward through apertures located in the flange;
- and
- a plurality of discrete arcuate keepers, each keeper extending partway around the circumference of the outer surface of the body upstream portion, each keeper having a flat upper surface configured to mate directly with the underside of the floor when the drain is installed, the upper surface having an opening that communicates with an axially oriented bore extending through the keeper, each keeper being operably connected to the adjusting means so that, in response to the adjusting means, each keeper can, independent of the other keepers, travel up the outer surface of the body upstream portion and engage the underside of the floor.
