Patent ID: 8172289

Claim:
A lifting link for anchors embedded in concrete panels, said lifting link comprising: a hollow substantially toroidal ring having a generally central hole, said ring having a base, an interior, a wall having a thickness, and a transverse slot through the base of the ring to receive an anchor, a hole opposite said base having a curved surface against which a substantially semicircular portion of a shackle or like connector bears, and an arcuate latch which travels in a curved path through the interior of said base and across said slot to engage said anchor, wherein said curved surface is at least partially circular in two substantially normal planes, one of said planes being a plane passing through said toroidal ring and the second of said planes including a radius of said toroidal ring and passing through said top and said base, and wherein a wall thickness of said ring is reduced in a vicinity of a top of said hole so that said curved path approaches said curved surface such that, with said shackle lying in said other plane, a center of lift of said shackle on said ring is moved away from said anchor.
