US Patent 10408003 Downhole tool

A downhole tool includes a slip member having an actuation surface, a bracing surface and an engagement surface. The slip member is pivotable about a pivot axis such that it can move between retracted and extended configurations. When the slip member is in the extended configuration, the engagement surface engages a bore wall. The downhole tool also includes a wedge member that has a wedge surface. The wedge member and the slip member are configured to move relative to each other such that the wedge surface of the wedge member engages the actuation surface of the slip member to cause the slip member to pivot about the pivot axis.
