Abstract

A link extension having an integral link connector disposed at one end and an eyelet disposed at an opposite end. The link connector is configured to connect to another link. The link connector has body having an upper portion and a lower portion, and a blocking member pivotably coupled to the upper portion by a pin.

First claim

The invention claimed is:

1. A link extension assembly, comprising:
a first link comprising an elongated support member having an eyelet disposed at a first end and another eyelet disposed at an opposite second end; and
a second link comprising:
an elongated support member having a first end and an opposite second end;
a link connector integrally formed with the first end of the elongated support member, wherein the link connector includes:
a body having an upper portion and a lower portion; and
a blocking member pivotably coupled to the upper portion by a pin; and

an eyelet disposed at the second end of the second link, wherein the eyelet disposed at the second end of the second link is substantially aligned with a first plane, wherein the link connector is substantially aligned with a second plane, wherein the first plane is orthogonal to the second plane such that the eyelet disposed at the second end of the second link and the link connector are oriented 90 degrees relative to each other; and

wherein the eyelets of the first link are substantially aligned with the first plane, and wherein one of the eyelets of the first link is coupled to the link connector such that the second link is suspended from the first link, and the upper portion of the body of the link connector has a rounded surface that defines a radius in a cross section of the upper portion extending along the first plane.

2. The link extension assembly of claim 1 , wherein another pin is disposed through the body and the blocking member to secure the link connector in a closed position.

3. The link extension assembly of claim 1 , wherein a center of gravity of the link connector is located in a middle of the body.

4. The link extension assembly of claim 1 , wherein one of the eyelets of the first link is secured to the upper portion of the body by the blocking member.

5. The link extension assembly of claim 4 , wherein one of the eyelets of the first link contacts the rounded surface of the upper portion of the body.

6. The link extension assembly of claim 5 , wherein the rounded surface transitions into a pair of substantially parallel sidewalls, the rounded surface extending between the pair of substantially parallel sidewalls to define the radius.

7. The link extension assembly of claim 1 , wherein the cross section of the upper portion of the body has a height that is different than a height of a cross section of the lower portion of the body.

8. The link extension assembly of claim 7 , wherein the cross section of the lower portion of the body has a first section of substantially parallel sidewalls and a second section of substantially parallel sidewalls, wherein the first section has a thickness less than a thickness of the second section, and the first section is disposed between the second section and the upper portion of the body.

9. The link extension assembly of claim 1 , wherein at least one of the eyelets of the first link has a size that is different than the eyelet of the second link.

10. The link extension assembly of claim 1 , wherein a load rating of the first link is different than a load rating of the second link.

11. The link extension assembly of claim 1 , wherein the eyelet of the second link is integrally formed with the second end of the elongated support member of the second link to form a single unitary body.

12. A link extension assembly, comprising:
a first link comprising an elongated support member having an eyelet disposed at a first end and another eyelet disposed at an opposite second end; and
a second link comprising:
an elongated support member having a first end and an opposite second end;
a link connector disposed at the first end of the second link, wherein the link connector includes:
a body having an upper portion and a lower portion; and
a blocking member pivotably coupled to the upper portion by a pin; and

an eyelet disposed at the second end of the second link, wherein the eyelet disposed at the second end of the second link is pivotable about a Y-axis and is substantially aligned with a first plane defined by an X-axis and a Z-axis, the first plane extending along a central opening of the eyelet disposed at the second end of the second link, wherein the link connector is pivotable about the X-axis and is substantially aligned with a second plane defined by the Y-axis and the Z-axis, the second plane extending through the body and the blocking member and extending orthogonally to a longitudinal axis of the pin, wherein the first plane is orthogonal to the second plane such that the eyelet disposed at the second end of the second link and the link connector are oriented 90 degrees relative to each other; and

wherein the eyelets of the first link are substantially aligned with the first plane, and wherein one of the eyelets of the first link is coupled to the link connector such that the second link is suspended from the first link.

13. The link extension assembly of claim 12 , wherein another pin is disposed through the body and the blocking member to secure the link connector in a closed position.

14. The link extension assembly of claim 12 , wherein a center of gravity of the link connector is located in a middle of the body.

15. The link extension assembly of claim 12 , wherein one of the eyelets of the first link is secured to the upper portion of the body by the blocking member.

16. The link extension assembly of claim 15 , wherein one of the eyelets of the first link contacts a rounded surface of the upper portion of the body, the rounded surface defining a radius in a cross section of the upper portion extending along the first plane.

17. The link extension assembly of claim 16 , wherein the rounded surface transitions into a pair of substantially parallel sidewalls, the rounded surface extending between the pair of substantially parallel sidewalls to define the radius.

18. The link extension assembly of claim 12 , wherein a cross section of the upper portion of the body has a height that is different than a height of a cross section of the lower portion of the body.

19. The link extension assembly of claim 18 , wherein the cross section of the lower portion of the body has a first section of substantially parallel sidewalls and a second section of substantially parallel sidewalls, wherein the first section has a thickness less than a thickness of the second section, and the first section is disposed between the second section and the upper portion of the body.
