1. A security chain anchor for use in securing an article to a fixed surface to prevent its theft, said anchor comprising:a base having a central aperture adapted to receive a device for securing and retaining the base to the fixed surface, a first surface defining a radially outer surface of a first radius, and a second surface defining a radially outer surface of a second radius less than said first radius and adapted to be disposed between said first surface and said fixed surface;a loop-bearing member having an annular edge disposed on said second surface and secured and adapated to be retained between said first surface and said fixed surface effective to permit substantially full rotation of the loop-bearing member about the base; anda rigid loop adapted to receive a tether and pivotally mounted on the loop-bearing member, said rigid loop capable of pivoting away from said fixed surface by an amount effective to allow attachment of said tether.2. The security chain anchor claimed in claim 1 wherein the loop is adapted to nest against the exterior of the loop-bearing member so that upper face presented by the anchor is substantially flat when the loop is not in use.3. The security chain anchor claimed in claim 1 wherein the loop is formed as part of an annulus of a larger diameter than the loop-bearing member.4. The security chain anchor claimed in claim 3 wherein the loop bearing member is substantially circular cylindrical, and the loop is part of a circular cylinder of larger diameter.5. The security chain anchor claimed in claim 4 wherein the loop bearing member is part of a segment of a notional sphere and the loop is part of a segment of a larger notional sphere that is substantially concentric with the notional sphere of the loop bearing member.6. The security chain anchor claimed in claim 1 wherein a radially inner face of the loop and a radially outer face of the loop bearing member nest together, each having a mating spherical curve.7. The security chain anchor claimed in claim 1 wherein on or both of the loop-bearing member and the loop are formed from pipe sections.8. The security chain anchor claimed in claim 1 wherein the base plate, loop-bearing member and loop are all concentrically positioned relative to the central aperture.9. The security chain anchor claimed in claim 8 wherein central aperture is counterbored and the anchor further comprises a blanking cap that fits, tightly within the counterbore.10. The security chain anchor claimed in claim 1, wherein the tether is a chain.
