Abstract
An apparatus includes a drain having an opening, the opening having an outboard edge, a cover having an underside having a portion including a downwardly extending curved section and an outer edge, wherein the portion extends a first distance beyond the outboard edge and wherein cover extends a second distance above the drain such that a ratio of the second distance to the first distance is about 1 or less and such that splash and aerosolization from under the cover beyond the cover is minimized.
Claims15
A drain apparatus for use with a sink, said drain apparatus comprising;
- a drain having an opening, said opening having an outboard edge,
- a cover covering said drain opening, said cover for extending completely above said sink and having an underside having a portion including a downwardly extending curved section and an outer edge, wherein said portion extends a first distance beyond said outboard edge and wherein said cover extends a second distance above said drain wherein said first distance is greater than or equal to said second distance and such that splash and aerosolization of fluid from under said cover beyond said cover is minimized;
- said cover having a first nut attaching thereto and extending downwardly therefrom;
- a second nut,
- a bolt, and
- a drain strainer for covering said drain, said drain strainer having an opening and a drain hole wherein said bolt extends through said opening to engage said first nut and to engage said second nut to attach said cover to said drain strainer and wherein said underside and said downwardly extending rim cooperate such that splash from said strainer beyond said cover is minimized.
3 more elements
A drain apparatus for use with a sink, said drain apparatus comprising;
- a drain having an opening, said opening having an outboard edge,
- a cover covering said drain opening, said cover for extending completely above said sink and having an underside having a portion including a downwardly extending curved section and an outer edge, wherein said portion extends a first distance beyond said outboard edge and wherein said cover extends a second distance above said drain wherein said first distance is greater than or equal to said second distance and such that splash and aerosolization of fluid from under said cover beyond said cover is minimized;
- a support for disposition within said drain and holding a nut in a central location therein;
- a bolt having a first end disposed in and extending through said cover and having a length and a threaded portion at second end thereof, distal from said cover, said bolt further comprising a depth limiter, wherein if said threaded portion is threaded into said nut, said depth limiter positions said bolt such that said cover is in position in said drain.
1 more element
An apparatus comprising;
- a drain having an opening, said opening having an outboard edge;
- a cover covering said drain and having an underside having a portion including a downwardly extending curved section and an outer edge, wherein said portion extends a first distance beyond said outboard edge and wherein said cover extends a second distance above said drain such that splash and aerosolization of fluid from under said cover beyond said cover is minimized said cover having:
- a first nut attaching thereto and extending downwardly therefrom;
- a second nut;
- a bolt;
- and
- a drain strainer for covering said drain, said drain strainer having an opening and a drain hole wherein said bolt extends through said opening to engage said first nut and to engage said second nut to attach said cover to said drain strainer and wherein said underside and said downwardly extending rim cooperate such that splash from said strainer beyond said cover is minimized.
4 more elements
A drain apparatus for use with a sink, said drain apparatus comprising;
- a drain having an opening, said opening having an outboard edge;
- a cover covering said drain opening and having an underside having a portion including a downwardly extending curved section and an outer edge, wherein said portion extends a first distance beyond said outboard edge and wherein said cover extends a second distance above said drain such that splash and aerosolization of fluid from under said cover beyond said cover is minimized;
- a support for disposition within said drain and holding a nut in a central location therein;
- a bolt having a first end disposed in and extending through said cover and having a length and a threaded portion at second end thereof, distal from said cover, and
- said bolt further comprising a depth limiter, wherein if said threaded portion is threaded into said nut, said depth limiter positions said bolt such that said cover is in position in said drain.
2 more elements
A drain apparatus, said drain apparatus comprising;
- a sink,
- a drain in said sink, said drain having an opening, said opening having an outboard edge,
