The link connector has a body having an upper portion and a lower portion. A first blocking member is pivotably coupled to the upper portion of the body by a pin member. A second blocking member is pivotably coupled to the lower portion of the body by a pin member. The first and second blocking members are movable between an open position and a closed position such that when in the closed position the link connector forms an 8 shape. ## Claims ### Claim 1 A link connector system, comprising: a first link; a second link; and a link connector, comprising: a body having an upper portion and a lower portion; a first blocking member pivotably coupled to the upper portion of the body by a pin member, wherein an eyelet of the first link is secured to the upper portion of the body by the first blocking member; and a second blocking member pivotably coupled to the lower portion of the body by a pin member, wherein an eyelet of the second link is secured to the lower portion of the body by the second blocking member, wherein the first and second blocking members are movable away from the body into an open position to allow insertion or removal of the eyelets, and movable toward the body into a closed position to secure the eyelets, and wherein when in the closed position, the link connector forms an 8 shape. ### Claim 2 (depends on 1) The link connector system of claim 1, wherein a center of gravity of the link connector is located in a middle of the 8 shape. ### Claim 3 (depends on 1) The link connector system of claim 1, wherein the eyelet of the first link contacts a rounded surface of the upper portion of the body. ### Claim 4 (depends on 1) The link connector system of claim 1, wherein the eyelet of the second link contacts a rounded surface of the lower portion of the body. ### Claim 5 (depends on 1) The link connector system of claim 1, wherein the first link and the second link have the same length. ### Claim 6 (depends on 1) The link connector system of claim 1, wherein the first link and the second link have different lengths. ### Claim 7 (depends on 1) The link connector system of claim 1, wherein a cross section of the upper portion of the body is the same as a cross section of the lower portion of the body when taken across the same section line through the body. ### Claim 8 (depends on 1) The link connector system of claim 1, wherein the upper portion of the body is configured to support a link having a size that is different than a size of a link that is supported by the lower portion of the body. ### Claim 9 (depends on 1) The link connector system of claim 1, wherein the upper portion of the body is configured to support a link having a load rating that is different than a load rating of a link that is supported by the lower portion of the body. ### Claim 10 (depends on 1) The link connector system of claim 1, wherein an outer profile of a cross section of the upper portion of the body has a height that is different than a height of an outer profile of a cross section of the lower portion of the body when taken across the same section line through the body. ### Claim 11 (depends on 1) The link connector system of claim 1, wherein a lower surface of an outer profile of a cross section of the upper portion of the body has a radius that is different than a radius of an upper surface of an outer profile of a cross section of the lower portion of the body when taken across the same section line through the body. ### Claim 12 A link connector system, comprising: a first link; a second link; and a link connector, comprising: a body having an upper portion and a lower portion; a first blocking member pivotably coupled to the upper portion of the body by a pin member at a first end of the first blocking member, wherein an eyelet of the first link is secured to the upper portion of the body by the first blocking member; a second blocking member pivotably coupled to the lower portion of the body by a pin member at a first end of the second blocking member, wherein an eyelet of the second link is secured to the lower portion of the body by the second blocking member, wherein the first and second blocking members are movable away from the body into an open position to allow insertion or removal of the eyelets, and movable toward the body into a closed position to secure the eyelets; and wherein when in the closed position, the link connector forms an 8 shape, the first blocking member is secured to the body by a pin member at a second end of the first blocking member, and the second blocking member is secured to the body by a pin member at a second end of the second blocking member. ### Claim 13 (depends on 12) The link connector system of claim 12, wherein the pin member at the first end of the first blocking member, the pin member at the second end of the first blocking member, the pin member at the first end of the second blocking member, and the pin member at the second end of the second blocking member are disposed through a plurality of openings formed in the body and a corresponding plurality of openings formed in the first blocking member and the second blocking member. ### Claim 14 (depends on 13) The link connector system of claim 13, wherein a cross section of the upper portion of the body is the same as a cross section of the lower portion of the body when taken across the same section line through the body. ### Claim 15 (depends on 13) The link connector system of claim 13, wherein the upper portion of the body is configured to support a link having a size that is different than a size of a link that is supported by the lower portion of the body. ### Claim 16 (depends on 13) The link connector system of claim 13, wherein the upper portion of the body is configured to support a link having a load rating that is different than a load rating of a link that is supported by the lower portion of the body. ### Claim 17 (depends on 13) The link connector system of claim 13, wherein an outer profile of a cross section of the upper portion of the body has a height that is different than a height of an outer profile of a cross section of the lower portion of the body when taken across the same section line through the body. ### Claim 18 (depends on 13) The link connector system of claim 13, wherein a lower surface of an outer profile of a cross section of the upper portion of the body has a radius that is different than a radius of an upper surface of an outer profile of a cross section of the lower portion of the body when taken across the same section line through the body.
