ABSTRACT:
A device for attaching a sink rim, which is either integral with a sink or which is a discrete structure attached to the sink, to an aperture in a drainboard includes a rotatable member appropriately attached to the sink rim which rotatable member engages the edge surfaces of the drainboard aperture as the sink is lowered into the aperture, thereby securing the sink in the aperture. The rotatable member is mounted on a bracket that is in turn affixed to a downwardly extending flange conventionally provided on the sink rim. The rotatable member has a periphery with teeth or other edge surface engaging members thereon. The rotatable member can be generally circular in configuration and can be mounted for eccentric rotation so that its plane of rotation is generally perpendicular to the edge surface of the aperture. When the rotatable member is eccentrically mounted, the teeth will progressively move outwardly relative to the sink and sink rim as the rotatable member rotates in a first direction, causing the teeth to bite into the drainboard as the sink is lowered into the aperture. A spring-like pawl engages the teeth on the rotatable member to prevent it from rotating in the opposite direction after the sink is positioned in the aperture. The sink is thereby secured in the aperture to eliminate any possibility of retrograde movement of the sink after installation.
