Abstract

Swivel shackle can be configured to accept different sizes and designs of the shackles. The swivel shackle configurations can include a swivel assembly, which can include one or more coupling interfaces to allow coupling with shackles having different arc sizes and/or different designs.

Claims (61)

1. A swivel shackle comprising

a first portion;

a second portion, wherein the second portion is rotatably coupled to the first portion, wherein the second portion comprises a coupling interface for attaching replaceable shackles having different arc sizes;

a shackle element, wherein the shackle element comprises a desired arc size, wherein the shackle element is coupled to the second portion at the coupling interface,

wherein the second portion is coupled to the first portion through a ball swivel.

2. A swivel shackle as in claim 1

wherein the desired arc size is selected based on a current usage of the swivel shackle.

3. A swivel shackle as in claim 1

wherein the shackle element is pivotally mounted to the coupling interface for the shackle element to be rotatable relative to the second portion.

4. A swivel shackle as in claim 1

wherein the second portion is further pivotally coupled to the first portion for the shackle element to form different angles with the first portion.

5. A swivel shackle as in claim 1

wherein the first portion comprises a second coupling interface for attaching replaceable shackles having different arc sizes,

wherein the swivel shackle further comprises a second shackle element, wherein the second shackle element comprises a desired arc size, wherein the second shackle element is coupled to the first portion at the second coupling interface.

6. A swivel shackle comprising:

a first portion;

a second portion, wherein the second portion is rotatably coupled to the first portion, wherein the second portion comprises a coupling interface for attaching replaceable shackles having different arc sizes;

a shackle element, wherein the shackle element comprises a desired arc size, wherein the shackle element is coupled to the second portion at the coupling interface,

wherein the coupling interface comprises through openings, wherein the through openings comprise a larger top section facing away from the first portion, and a smaller bottom section facing the first portion, wherein the through openings are configured for accepting a replaceable shackle inserting from the larger section,

wherein the shackle element comprises a curve bail having end portions configured to be mated with the through openings.

7. A swivel shackle as in claim 6

wherein the shackle element is pivotally mounted to the coupling interface for the shackle element to be rotatable relative to the second portion.

8. A swivel shackle as in claim 6

wherein the second portion is further pivotally coupled to the first portion for the shackle element to form different angles with the first portion.

9. A swivel shackle as in claim 6

wherein the first portion comprises a second coupling interface for attaching replaceable shackles having different arc sizes,

wherein the swivel shackle further comprises a second shackle element, wherein the second shackle element comprises a desired arc size, wherein the second shackle element is coupled to the first portion at the second coupling interface.

10. A swivel shackle as in claim 6

wherein the second portion is coupled to the first portion through a shaft swivel.

11. A swivel shackle as in claim 1

wherein the coupling interface comprises through openings, wherein the through openings are configured for accepting a replaceable shackle inserting from a section facing away from the first portion,

wherein the shackle element comprises two separate curve arms, wherein the two separate curve arms are linked by a pin, wherein end sections of the two separate curve arms are configured to be mated with the through openings.

12. A swivel shackle as in claim 1

wherein the coupling interface comprises through openings or slits, wherein the through openings or slits comprise a larger bottom section facing away from the first portion, and a smaller top section facing the first portion, wherein the through openings are configured for accepting a replaceable shackle inserting from the larger section,

wherein the shackle element comprises a curve bail, wherein the curve bail comprises first two open end sections linked by a pin, wherein the curve bail comprises a second end section configured to be mated with the through openings or slits.

13. A swivel shackle as in claim 1

wherein the coupling interface comprises through openings, wherein the through openings are configured for accepting a replaceable shackle inserting from a section facing the first portion,

wherein the shackle element comprises two separate curve arms, wherein the two separate curve arms are linked by a pin, wherein end sections of the two separate curve arms are configured to be mated with the through openings,

wherein end sections of the two separate curve arms comprise elements for one-way securing the curve arms to the coupling interface.

14. A swivel shackle as in claim 1

wherein the coupling interface are configured for accepting a replaceable shackle rotatably secured from a side section of the second portion,

wherein the side section is between a section facing the first portion and a section facing away from the first portion,

wherein the coupling interface is configured for the replaceable shackle to be pivotally mounted to be rotatable relative to the second portion.

15. A swivel shackle comprising:

a first portion;

a second portion, wherein the second portion is rotatably coupled to the first portion, wherein the second portion comprises a coupling interface for attaching replaceable shackles having different arc sizes;

a shackle element, wherein the shackle element comprises a desired arc size, wherein the shackle element is coupled to the second portion at the coupling interface,

wherein the coupling interface comprises slits, wherein the slits are configured for accepting a replaceable shackle inserting from a side section of the second portion, wherein the side section is between a section facing the first portion and a section facing away from the first portion,

wherein the shackle element comprises a curve bail having end portions configured to be mated with the slits,

wherein the swivel shackle further comprises plugs for securing the shackle element with the coupling interface.

16. A swivel shackle as in claim 15

wherein the shackle element is pivotally mounted to the coupling interface for the shackle element to be rotatable relative to the second portion.

17. A swivel shackle as in claim 15

wherein the second portion is further pivotally coupled to the first portion for the shackle element to form different angles with the first portion.

18. A swivel shackle as in claim 15

wherein the first portion comprises a second coupling interface for attaching replaceable shackles having different arc sizes,

wherein the swivel shackle further comprises a second shackle element, wherein the second shackle element comprises a desired arc size, wherein the second shackle element is coupled to the first portion at the second coupling interface.

19. A swivel shackle as in claim 15

wherein the second portion is coupled to the first portion through a shaft swivel.

20. A swivel shackle as in claim 15

wherein the desired arc size is selected based on a current usage of the swivel shackle.
