For lifting loads there is provided an eyebolt with a collar swivelly mounted on a stud so as to freely rotate in a horizontal plane throughout a full 360°. A lifting ring has oppositely disposed pivot pins in swivel engagement with the collar to allow the ring to pivot in a vertical arc as well as to rotate about the stud. The stud in turn is adapted to be anchored in fixed position to the load, whatever the load may be. Enlargements at free ends of the pivot pins serve to resist pulling the pins free of the collar when a heavy lifting force is applied to the lifting ring.

A multi-position fixture for fixed attachment to a base, said fixture comprising a base-engaging anchor assembly, respective outer and inner interlock members having potential axial movement relative to each other to interlock positions, at least one of said interlock members having an operative swivel engagement with the anchor assembly and adapted to rotate throughout substantially a full circle, a ring member comprising a loop and a transversely disposed pivot pin structure having opposite elements respectively joined to said loop in a spaced relatively axial relationship with respect to each other, each said element having a captive relatively smaller end at a junction with the loop and a free relatively larger end, said interlock members including complementary retention means on respective diametrically opposite sides of the fixture, each said complementary retention means having opposite pin retention portions movable relative to each other to interlock engagement with the pivot pin structure whereby in operation the pivot pin structure is adapted to occupy a locked-in location between said interlock members during movement of said ring member throughout an arc of substantially a half circle for all full circle positions of rotation of said outer interlock member.
