Clamp assembly for self-rimming sinks or basins

A clamp assembly for use with a self-rimming sink or basin intended for mounting through an opening in a supporting counter structure which has an upper surface over which the rim of said sink or basin will fit, and having an under surface, where said sink or basin has a bowl and a plurality of brackets secured at least intermittently around the outer surface of said bowl at positions intermediate the height of said bowl, and where each of said brackets has a downwardly facing opening from the top thereof adjacent the outer surface of said bowl at said bracket, comprising:

• a generally L-shaped clamp structure having a first, generally horizontally disposed arm, and a second, generally vertically disposed leg depending downwardly from said arm;
• a bolt threadably received in and passed substantially perpendicularly through said arm, and having engageable means at the lower end of said bolt by which said bolt may be turned, and means at the upper end of said bolt for engaging the under surface of said supporting structure;
• and a clamp arm spaced from the side of said leg opposite said arm, and depending downwardly from a clamping shoulder upstanding from said leg, said clamp arm being substantially parallel to the contiguous portions of said leg and being spaced therefrom a sufficient distance to accommodate one of said brackets;
• where the lower portion of said leg is offset from the upper portion thereof in a direction away from said arm and to an extent that it will contact the outer surface of said bowl at a place below the bracket with which said clamp arm is engaged, and so as to keep said bolt substantially in a vertical orientation.
