Patent ID: 7654500

Claim:
An adjustable mounting for hanging an object on a wall a generally disc shaped mounting element having an eccentrically located hole extending therethrough, the disc also having a perimeter and a back surface that engages a front surface of the wall such that the mounting element and the front surface of the wall may exert frictional forces therebetween in a plane that is parallel to the front surface; a threaded fastener passing through the hole in said mounting element and into said wall and adapted to be secured by said wall and tightened against said mounting element to press said mounting element against the front surface of said wall to a selective degree to create a sufficient frictional force between said surface of said wall and said mounting element to prevent rotation of said mounting element about said fastener or to be loosened to allow rotation of said mounting element on said fastener; and an engagement zone on said mounting element perimeter engaged with a hanging support attached to said object, said zone being located eccentrically with respect to said hole, the zone being vertically displaced when said mounting element is rotated about said fastener so as to position said object to a desired location on said wall, said mounting element thereafter able to be frictionally held against said wall surface in said desired location, so that an operator may adjust the object's vertical position from a front surface of the wall without recourse to a back surface thereof; wherein the engagement zone comprises a groove that is defined by two series of teeth arranged about said perimeter lying on either side of said mounting element; and further including protrusions on the back surface of the mounting element to prevent slippage out of an adjusted position.
