Patent ID: 7712783

Claim:
A column mount comprising: a base fixture defining a base fixture aperture; a clamp float defining a float aperture, the clamp float in engagement with the base fixture within the base fixture aperture; a first ring in engagement with the clamp float within the float aperture, the first ring defining a first ring aperture; and a second ring in engagement with the first ring within the first ring aperture; wherein the base fixture comprises a base fixture first half ring and a base fixture second half ring defining the base fixture aperture having a base fixture inner surface defining an inner diameter operable to accept the clamp float therein, the base fixture first half ring and the base fixture second half ring being coupled, the clamp float including a float first half ring and a float second half ring defining a float outer diameter and defining the float aperture defining a float inner diameter, the float first half ring and the float second half ring being coupled, the clamp float having a float outer surface that is operable for cooperative engagement with the base fixture inner surface, the clamp float further comprising a float inner surface, the clamp float operable to be captured in the base fixture aperture such that the clamp float may swivel and rotate therein, the first ring comprising a first ring first half and a first ring second half being coupled and defining a first ring outer surface defining a first ring outer diameter and defining the first ring aperture defining a first ring inner diameter, the first ring outer surface operable for cooperative engagement with the float inner surface of the clamp float, the first ring operable to be captured in the clamp float aperture such that the first ring is held in axial and traverse alignment therein, the second ring comprising a second ring first half and a second ring second half being coupled defining a second ring outer surface defining a second ring outer diameter and defining a second ring aperture defining a second ring inner diameter, the second ring outer surface is operable for cooperative engagement with the first ring inner surface, the second ring operable to be captured in the first ring aperture such that the second ring is held in axial and traverse alignment therein, wherein the float first half ring and the float second half ring are retained in the base fixture aperture by the engagement of fasteners operable for coupling the base fixture first half ring and the base fixture second half ring, wherein the float inner surface has a keyway shape for complementary engagement with the first ring outer surface having a complimentary keyway shape.
