Patent ID: 7905465

Claim:
A shimless aligner, for use with a foot connected to a base by means of a hold-down bolt, comprising: a top plate, adjacently disposed below the foot, having a hole for receiving the hold-down bolt and having a slanted bottom surface; a taper wedge, adjacently disposed below the top plate, having a slanted top surface slidably engaging the slanted bottom surface of the top plate, wherein the taper wedge has a longitudinal slot for slidably receiving the hold-down bolt; a bottom plate, adjacently disposed below the taper wedge, having a hole for receiving the hold-down bolt; and a back plate attached substantially perpendicularly at one end of the bottom plate, wherein said back plate has a lower portion that extends below the bottom plate and a threaded hole in that lower portion for a locking screw to engage the threaded hole and exert pressure against the base thereby preventing the bottom plate from rotating around the hold-down bolt; wherein said back plate has a middle portion that extends above the bottom plate and a threaded hole in the middle portion for a vertical alignment screw to engage the threaded hole in the middle portion and engage a complimentary threaded hole in the side of the taper wedge thereby allowing the taper wedge to slide along the length of the slot when the vertical alignment screw is rotated and thereby also preventing rotation of the taper wedge around the hold-down bolt.
