Abstract
A drain may include ligature resistant features to inhibit anchoring a ligature or string to or around the installed drain. A drain can include an inlet or upper opening, an outlet or lower opening, and a channel fluidly connecting the upper opening to the lower opening. The channel may be configured to prevent linear flow of fluid from the upper opening to the lower opening and to inhibit anchoring a ligature about any opening or portion of the drain.
Claims20
A drain comprising:
- an outer body having a central opening and an interior wall extending around the central opening;
- and
- an inner body coupled to the outer body and having a central surface positioned within the central opening of the outer body, the inner body having an exterior wall extending around a perimeter of the central surface, the exterior wall spaced radially inward from the interior wall of the outer body to form an annular gap therebetween, the inner body further including a lower wall spaced apart from the central surface and extending radially outward from the exterior wall of the inner body.
A drain comprising:
- an upper portion having an upper opening, the upper portion having a center axis;
- a lower portion coupled to the upper portion and having a lower opening;
- and
- a channel fluidly connecting the upper opening to the lower opening, the channel having an upper channel portion directing fluid flowing through the upper opening in a substantially radial direction toward a lower channel portion of the channel, the lower channel portion being radially offset from the upper opening.

A drain comprising:
- an upper portion having an upper opening;
- a lower portion having a lower opening;
- and
- a channel fluidly connecting the upper opening to the lower opening, the channel having an offset portion such that at least a portion of the channel has a serpentine shape preventing fluid flowing between the upper opening and the lower opening from moving along a linear path.
