Patent ID: 8037904

Claim:
An anchor mount, comprising: a substantially rigid stopper having a thrust flange joined to a first end of a stem portion with an axial bore extending between an external surface of the flange and a second end of the stem portion opposite from the flange, and a self-centering portion inclined between an overhanging portion of the flange and the stem portion and comprising a first dimension adjacent to and smaller than the overhanging portion of the flange and a second dimension distal from the flange that is smaller than the first dimension; a part-spherical coupler presented on the stopper thrust flange opposite from the stem portion; a plug positioned adjacent to the stem portion of the stopper opposite from the thrust flange thereof, the plug comprising a substantially resiliently deformable plug body having a maximum dimension between opposing first and second end surfaces thereof that is smaller than the first dimension of the self-centering portion of the stopper, and comprising an axial bore extended longitudinally there through between the opposing first and second end surfaces thereof; an elongated shaft extendable through the respective axial bores of the stopper and the plug and having a threaded portion thereof extendable from the second end surface of the plug when the first end surface thereof is positioned substantially adjacent to the second end of the stem portion of the stopper and the respective axial bores of the stopper and the plug being substantially aligned; and a substantially rigid end cap having first and second spaced apart end faces with an axial bore there between sized to receive the threaded shaft there through, the first face of the end cap being structured with an anti-rotation mechanism operable for resisting rotation of the end cap relative to the plug body when the axial bore of the end cap is received on the shaft with the first face of the end cap adjacent to the plug body; and means for reversibly moving the end cap along the elongated shaft relative to the second end of the stem portion.
