Abstract

A hoist ring assembly for mounting on a load member includes a bolt having a circumferential recess, a support member having a bolt passage for receiving the bolt, and a pin passage transverse to and intersecting the bolt passage. A load bearing ring has legs aligned with the pin passage, and one or two pins are inserted into the pin passage so as to interengage with the recess to hold the bolt and support member against separation and to support the load ring for pivotal movement relative movement relative to the support member and for pivotal movement with the support member relative to the bolt. In one arrangement the pin passage is offset from the bolt passage and a single pin extends through the support member and engages in the recess of the bolt. In another arrangement, the pin passage opens into the recess on diametrically opposite sides thereof, and a pair of pins have inner ends received in the recess.

Claims

1. A hoist ring assembly for threaded engagement with a load member, said hoist ring assembly comprising:

a bolt having a head portion, a shank portion and a bolt axis, said shank portion having a threaded portion and an unthreaded portion, said unthreaded portion having a circumferentially extending recess, a load bearing member having legs, a support member having a bolt passage for receiving and supporting said bolt, said support member having pin passage means therein having a pin passage axis, said pin passage means extending transverse to and intersecting said bolt passage, and pin means extending into said pin passage means and said recess and having outer ends each interconnected with a different one of said legs, whereby said load bearing member is pivotal relative to said support member about said pin passage axis and is pivotal with said support member about said bolt axis.

2. The hoist ring assembly as defined in claim 1, wherein said load bearing member is substantially U-shaped and has generally parallel legs, said legs having ends and a cross member interconnecting said legs at a location spaced from said ends.

3. The hoist ring assembly as defined in claim 2, wherein said support member includes a front surface, a back surface, and opposite side surfaces, said bolt passage extending between said front surface and said back surface and having a length, the length of said unthreaded shank portion being slightly greater than the length of said bolt passage, and said pin passage means extending between said side surfaces.

4. The hoist ring assembly as defined in claim 3, wherein said pin means comprises a cylindrical pivot pin and said pin passage means is adapted to receive said pivot pin.

5. The hoist ring assembly as defined in claim 2, wherein said support member includes a top surface, a bottom surface, and opposite side surfaces;

said bolt passage extending between said top surface and said bottom surface and having a length, the length of said unthreaded shank portion being slightly greater than the length of said bolt passage, and said pin passage means extending between said side surfaces.

6. The hoist ring assembly as defined in claim 5, wherein said pin means comprises two diametrically opposed cylindrical pivot pins, and said pin passage means is adapted to receive said pivot pins.

7. A hoist ring assembly for threaded engagement with a load member, said hoist ring assembly comprising:

a bolt having a head portion, a shank portion and a bolt axis, said shank portion having a threaded portion and an unthreaded portion, said unthreaded portion having a circumferentially extending recess, a load bearing member having generally parallel legs and means for interconnecting said legs, a support member having a front surface, a back surface, opposite side surfaces, a bolt passage for receiving and supporting said bolt, and pin passage means, said bolt passage extending between said front surface and said back surface and having a length, the length of said unthreaded shank portion being slightly greater than the length of said bolt passage, said pin passage means extending between said side surfaces and being transverse to and intersecting said bolt passage, pin means extending into said pin passage means and said recess and having a pin axis and outer ends each interconnected with a different one of said legs, whereby said load bearing member is pivotal relative to said support member about said pin axis and is pivotal with said support member about said bolt axis.

8. The hoist ring assembly as defined in claim 7, wherein said load bearing member is substantially U-shaped, said legs have ends, and said interconnecting means comprises a cross member interconnecting said legs at a location spaced from said ends.

9. The hoist ring assembly as defined in claim 8, wherein said pin means comprises a cylindrical pivot pin and said pin passage means is adapted to receive said pivot pin.

10. A hoist ring assembly for threaded engagement with a load member, said hoist ring assembly comprising:

a bolt having a head portion, a shank portion and a bolt axis, said shank portion having a threaded portion and an unthreaded portion, said unthreaded portion having a circumferentially extending recess, a load bearing member having generally parallel legs and means for interconnecting said legs, a support member having a top surface, a bottom surface, opposite side surfaces, a bolt passage for receiving and supporting said bolt, and pin passage means, said bolt passage extending between said top surface and said bottom surface and having a length;

the length of said unthreaded shank portion being slightly greater than the length of said bolt passage;

said pin passage means extending between said side surfaces, said pin passage means extending transverse to and intersecting said bolt passage, and pin means extending into said pin passage means and said recess and having a pin axis and outer ends each interconnected with a different one of said legs, whereby said load bearing member is pivotal relative to said support member about said pin passage axis and is pivotal with said support member about said bolt.

11. The hoist ring assembly as defined in claim 10, wherein said load bearing member is substantially U-shaped, said legs have ends, and said interconnecting means comprises a cross member interconnecting said legs at a location spaced from said ends.

12. The hoist ring assembly as defined in claim 11, wherein said pin means comprises two diametrically opposed cylindrical pivot pins, and said pin passage means is adapted to receive said pivot pins.
