Abstract

For lifting loads there is provided an eyebolt with an annular ring swivelly mounted on a stud so as to freely rotate in a horizontal plane through a full 360°. A lifting loop has oppositely disposed pivot pins in swivel engagement with the annular ring to allow the loop 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. Snap rings at free ends of the pivot pins serve to resist pulling the pins free of the annular ring when a heavy lifting force is applied to the lifting loop.

Claims

1. A multi-position fixture for attachment to a load comprising a load-engaging anchor means including a threaded stud, a retention means having a swivel engagement with the anchor means and adapted to rotate throughout substantially a full circle, a substantially arcuate lifting loop and a transversely disposed pivot structure having opposite shoulder pin elements respectively joined to said loop in a fixed spaced axial relationship with respect to each other, each said shoulder pin element having a captive end at a junction with the loop and a free end, said retention means comprising an annular ring member having opposite parallel faces and inside and outside walls and retention members adjacent opposite faces of said ring member, said ring member having bearing pockets on respective diametrically opposite sides extending between said walls, each pocket having a form and size complementary with respect to a corresponding free end of the shoulder pin element and locking means for the shoulder pin elements, said locking means comprising a recess for each bearing pocket located in the inside wall of the annular ring member in alignment with the corresponding bearing pocket and a releasable fastener for each recess, each recess having an initially open side and open ends, each recess and the corresponding shoulder pin element being receptive of one of said releasable fasteners, the initially exposed sides of said recesses being covered by one of said retention members, said loop having a path of movement throughout an arc of substantially a half circle for all positions of rotation of said annular ring member.

2. A multi-position fixture as in claim 1 wherein each said recess is a slot extending between the opposite parallel faces of the ring member.

3. A multi-position fixture as in claim 1 wherein each said recess is a slot extending between the opposite parallel faces of the ring member, and said retention means comprises the retention members for opposite faces of the ring member, said retention members having operative positions overlying corresponding opposite ends of the respective slots.

4. A multi-position fixture as in claim 3 wherein one of said retention members comprises a relatively central sleeve section extending into engagement with the other of said retention members and which occupies a position within the inside wall of the ring member overlying said slots whereby the ring member is captured by said retention members in a rotatable relationship.
