Abstract
A drain assembly for providing a drain passage for fluid flow from a surface to the drainpipe of a plumbing system. The surface would typically be that of a structure such as that of a floor, a floor of a shower or floor of a bathtub. The drain assembly includes a multi-channel cove wherein each flow channel is configured or curved in such a way to prevent the passage of a ligation (e.g., wire, cord, or rope) through the channels to allow the ligation to be tied to the cover.
Claims20
A multi-channel, ligation resistant drain cover having a top side and a bottom side, the cover comprising:
- a top plate including a top surface, a bottom surface, a periphery, a first interior fluid flow opening extending between the top and bottom surface, and a first exterior fluid flow opening extending between the top and bottom surface and located between the interior fluid flow opening and the periphery;
- an exterior fluid guide wall extending from the bottom surface between the periphery and the exterior fluid flow opening, the exterior fluid guide wall including a first diverter wall displaced from the bottom surface and extending radially inward toward a central axis of the top plate at a first angle from the exterior fluid guide wall;
- an intermediate fluid guide wall extending from the bottom surface between the interior and exterior flow openings, the intermediate fluid guide wall including a second diverter wall displaced from the bottom surface and extending radially inward toward the central axis of the top plate at a second angle from the intermediate fluid guide wall, the exterior and intermediate fluid guide walls being located to form a curved exterior fluid flow channel extending from the top surface, through the exterior fluid flow opening and exiting at the bottom side of the cover at an exterior exit;
- and
- an interior fluid guide wall extending from the bottom surface and cooperating with the intermediate fluid guide wall to form a curved interior fluid flow channel separate from the exterior fluid flow channel and extending from the top surface, through the interior fluid flow opening and exiting at the bottom side of the cover at an interior exit separate from and displaced from the exterior exit.

A multi-channel, ligation resistant drain assembly comprising:
- an interface for creating a sealed fluid channel between a flow and a drainpipe, the interface including a flange for attachment to a floor surface, the flange being joined to a tubular portion for attachment to the drainpipe;
- and
- a drain cover including:
- a top plate attachable to the flange and including a top surface, a bottom surface, a periphery, a first interior fluid flow opening extending between the top and bottom surface, and a first exterior fluid flow opening extending between the top and bottom surface and located between the interior fluid flow opening and the periphery;
- an exterior fluid guide wall extending from the bottom surface between the periphery and the exterior fluid flow opening, the exterior fluid guide wall including a first diverter wall displaced from the bottom surface and extending radially inward toward the central axis of the top plate at a first angle from the exterior fluid guide wall;
- an intermediate fluid guide wall extending from the bottom surface between the interior and exterior flow openings, the intermediate fluid guide wall including a second diverter wall displaced from the bottom surface and extending radially inward toward the central axis of the top plate at a second angle from the intermediate fluid guide wall, the exterior and intermediate fluid guide walls being located to form a curved exterior fluid flow channel extending from the top surface, through the exterior fluid flow opening and exiting at the periphery of the cover at an exterior exit;
- and
- an interior fluid guide wall extending from the bottom surface and cooperating with the intermediate fluid guide wall to form a curved interior fluid flow channel separate from the exterior fluid flow channel and extending from the top surface, through the interior fluid flow opening and exiting at a bottom side of the cover at an interior exit separate from and displaced from the exterior exit.

A multi-channel, ligation resistant drain cover having a top side and a bottom side, the cover comprising:
- a circular top plate including a top surface, a bottom surface, a periphery, three interior fluid flow openings extending between the top and bottom surface, and three exterior fluid flow openings extending between the top and bottom surface and located between the interior fluid flow opening and the periphery;
- an exterior fluid guide wall extending from the bottom surface between the periphery and the exterior fluid flow openings, the exterior fluid guide wall including a first diverter wall displaced from the bottom surface and extending radially inward toward the central axis of the top plate at a first angle from the exterior fluid guide wall;
- an intermediate fluid guide wall extending from the bottom surface between the interior and exterior flow openings, the intermediate fluid guide wall including a second diverter wall displaced from the bottom surface and extending radially inward toward the central axis of the top plate at a second angle from the intermediate fluid guide wall, the exterior and intermediate fluid guide walls being located to form a curved exterior fluid flow channel extending from the top surface, through the exterior fluid flow openings and exiting at the bottom side of the cover at an exterior exit;
- an interior fluid guide wall extending from the bottom surface and cooperating with the intermediate fluid guide wall to form a curved interior fluid flow channel separate from the exterior fluid flow channel and extending from the top surface, through the interior fluid flow openings and exiting at the bottom side of the cover at an interior exit separate from and displaced from the exterior exit;
- three interior dividing walls extending between the intermediate fluid guide wall and the interior fluid guide wall to form three separate interior flow paths through the interior fluid flow channel associated with each of the interior flow openings;
- and
- three exterior dividing walls extending between the intermediate fluid guide wall and the exterior fluid guide wall to form three separate exterior flow paths through the exterior fluid flow channel associated with each of the exterior flow openings.
