Patent Images
1. A funnel assembly for connection to a floor drain grate, comprising:
- a drain funnel of a pre-determined height having an upper wide mouth portion and a lower stem portion;
a separate low-profile drain funnel base of a pre-determined height smaller than said pre-determined height of said drain funnel; and
fasteners for securing said low-profile drain funnel base to an upper surface of an underlying floor drain grate such that the low-profile drain funnel base extends above the floor drain grate and floor in an upright fixed position;
said stem portion of said drain funnel being of a configuration for being removably securable to said low-profile drain funnel base without use of separate fasteners and without use of tools such that, in a locked position, said stem portion of said drain funnel is in frictional engagement with said low-profile drain funnel base for positioning said drain funnel in an upright position extending above the floor drain grate and floor and, in a disengaged position, said drain funnel is completely removed from engagement with said low-profile drain funnel base without tools.

10. A system for eliminating splash from drain pipes that discharge from an elevation above a floor drain, comprising:
-
a drain grate mounted in a mouth of the floor drain; a drain funnel of a pre-determined height having a wide mouth portion and a cylindrical stem portion; a separate low-profile drain funnel base of a pre-determined height smaller than said pre-determined height of said drain funnel and having an annular sidewall with a lower end secured to said drain grate with fasteners such that the low-profile drain funnel base is fixed to said drain grate and extends above the drain grate and floor; said stem portion of said drain funnel being removably securable to said annular sidewall of said low-profile drain funnel base without use of separate fasteners and without use of tools such that, in a locked position, said cylindrical stem portion of said drain funnel is in frictional engagement with said low-profile drain funnel base for positioning said drain funnel in an upright position extending above the drain grate and floor and, in a disengaged position, said drain funnel is completely disengaged from said low profile drain funnel base without tools. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
