Abstract

Official abstract text for this publication.

A downhole tool including a mandrel, at least one moveable component mounted to the mandrel, and a locking ring mounted to the mandrel. The locking ring includes a plurality of locking ring segments that enable relative movement between the mandrel and the at least one moveable component. A plurality of circumferential spaces is arranged between corresponding ones of the locking ring segments. At least one load bar is arranged in at least one of the plurality of circumferential spaces. The at least one load bar is mechanically connected to the at least one moveable component.

First claim

Opening claim text (preview).

The invention claimed is: 1. A downhole tool comprising: a mandrel; at least one moveable component mounted to the mandrel; a locking ring mounted to the mandrel, the locking ring including a plurality of circumferentially spaced locking ring segments that enable relative movement between the mandrel and the at least one moveable component; a plurality of circumferential spaces arranged between corresponding ones of the plurality of circumferentially spaced locking ring segments; and at least one load bar slidingly received in at least one of the plurality of circumferential spaces, the at least one load bar being mechanically connected to the at least one moveable component. 2. The downhole tool according to claim 1 , wherein the lock bar does not project radially proudly of the locking ring. 3. The downhole tool according to claim 1 , wherein the at least one moveable component comprises a first moveable component and a second moveable component, the load bar being operatively connected between the first and second moveable components. 4. The downhole tool according to claim 3 , wherein the at least one load bar comprises a plurality of load bars arranged in corresponding ones of the plurality of circumferential spaces, each of the plurality of load bars being operatively connected to the first and second moveable components. 5. The downhole tool according to claim 3 , wherein the first moveable component is axially spaced from the second moveable component along the mandrel. 6. The downhole tool according to claim 3 , further comprising: a load bar link mechanically connecting each of the plurality of load bars. 7. The downhole tool according to claim 3 , wherein the first moveable component is a decoupling sleeve and the second moveable component comprises a seal body. 8. The downhole tool according to claim 1 , further comprising: one or more slip members selectively radially outwardly moveable relative to the mandrel. 9. The downhole tool according to claim 8 , wherein the at least one moveable component is operatively connected to the one or more slip members. 10. The downhole tool according to claim 1 , wherein each of the plurality of circumferentially spaced locking ring segments includes a first plurality of ridges and the at least one load bar includes a second plurality of ridges that is selectively aligned with the first plurality of ridges. 11. The downhole tool according to claim 1 , wherein the at least one load bar is axially shiftable relative to the plurality of locking ring segments.
