Abstract
Abstract This application covers an arrangement for connecting a sink or lavatory within the opening of a countertop, the connecting means including a clamp structure for establishing a firm connection between the units regardless of the thickness or depth of the countertop. A rail or rails may be welded or otherwise affixed to the underside of the lavatory and each such rail includes two similar U-shaped members for receiving between them and supporting the head of an elongated screw. The screw is adjustably mounted on an elongated bracket of uniform width which provides a plurality of narrow rectangular openings along its length for receiving one end of a clip of slightly lesser width which has an opening threadedly adjustable along the shank of the screw. The clip has an upturned end which has an angular disposition so that is may be driven against or into the underside of the countertop when the screw is adjusted in position. The other end of the clip is normal to the central segment of the clip and parallels the bracket. By having a plurality of similar narrow parallel openings in the bracket, the clip may be readily inserted through any one of the openings to meet the geometrical requirements for attachment to any countertop regardless of the thickness or depth of the countertop within a wide limiting range.

Total Claims: 14
Claim 1
Independent Claim
144 words
Mechanism for installing a flanged plumbing fixture, such as a stainless steel sink or lavatory, on any of a plurality of countertops having widely different depths or thicknesses, comprising a rail member affixed to the underside of the flange of the fixture, an elongated screw member having a head which may be slid along and supported by the rail member, a flat clip having a threaded opening to receive and grip the screw member, said clip having one end turned-up to contact the undersurface of the countertop, an elongated bracket having a plurality of substantially horizontal slots any one of which may receive the other end of said clip, the bracket having a platform to be positioned in contact with the rail member, the screw member being rotatable to change the relative position of the clip with respect to the underside of the countertop.
Claim 2
Dependent Claim
