Floor drain
First Claim
1. A floor drain system, comprising:
- a generally rectangular drain grate having a plurality of drain apertures; and
a drain body, having a circular lower portion defining an outlet and configured to mate with an underdrain structure, and an upper portion defining an inlet, configured to receive the drain grate in a frictional fit, the drain body including an integral grout rim surrounding the inlet, having a knife-tapered top edge, and further including an undercut rim around an outer perimeter of the inlet, the undercut rim having a bottom surface angled radially outward and downwardly from the drain body.

Abstract
A floor drain system includes a generally rectangular drain grate having a plurality of drain apertures, and a drain body, having a circular lower portion defining an outlet and configured to mate with an underdrain structure, and an upper portion defining an inlet configured to receive the drain grate in a frictional fit. The drain body includes an integral grout rim surrounding the inlet, having a knife-tapered top edge, configured to reduce the visibility of the grout rim between the surrounding material and the grate. The drain body further includes an undercut rim around an outer perimeter of the inlet, the undercut rim having a bottom surface angled upward toward the drain body. The drain body can also include dovetail-shaped buttresses extending outward from the drain body, having tapered surfaces angled toward the drain body, thereby to mechanically interlock the drain body with hardened grout therearound.

11. A floor drain, comprising:
-
a height-adjustable drain body, having a circular lower portion defining an outlet, the lower portion being configured to interconnect to an underdrain structure, and a generally rectangular upper portion defining an inlet, the upper portion including an integral grout rim surrounding the inlet and having a knife-tapered top edge, and further including an undercut rim around an outer perimeter of the inlet, the undercut rim having a bottom surface angled radially outward and downwardly from the drain body, and dovetail-shaped buttresses extending outward from the drain body, having tapered surfaces angled toward the drain body, thereby to mechanically interlock the drain body with hardened grout there around; and a generally rectangular drain grate, supported by the drain body, having a plurality of drain openings, configured to insert into the inlet with an interference fit, whereby the drain grate is removably secured to the drain body. - View Dependent Claims (12, 13, 14)

15. A floor drain assembly, comprising:
-
a drain body, having a generally rectangular upper portion defining an inlet aperture, and a circular lower portion defining an outlet in fluid communication with the inlet aperture, the lower portion having helical threads configured to threadedly interconnect with an underdrain, whereby a height of the inlet can be adjusted by rotating the drain body about a central axis, and the upper portion including an integral grout rim surrounding the inlet and having a knife-tapered top edge, and further including an undercut rim around an outer perimeter of the inlet, the undercut rim having a bottom surface angled radially outward and downwardly from the drain body, and dovetail-shaped buttresses extending outward from the drain body, having tapered surfaces angled toward the drain body, thereby to mechanically interlock the drain body with hardened grout there around; a generally rectangular drain grate, having a plurality of drain openings, surrounded by the grout rim and supported by the drain body; and an underdrain attached to the outlet of the drain body. - View Dependent Claims (16, 17, 18, 19)
