US Patent 7762512 Self leveling adaptor

A self leveling adaptor that forms a substantially level and planar mounting surface on a curved or otherwise irregular external surface for mounting of an external device having a substantially planar mounting base. The self leveling adaptor of the invention includes a rigid plate having a substantially planar mounting surface and a pliable boot thereabout that is structured to substantially conform to the curved or otherwise irregular external surface. Three nipples between the rigid plate and the external surface cause the rigid plate to be firmly seated against the external surface without rocking.
