Claim Text:
1. A subterranean tool comprising a lock assembly wherein said lock assembly comprises relatively moveable components to enable support of a collet assembly at one or more desired subterranean locations of a surrounding tubular defining a wall in a borehole and to prevent operation of said collet assembly for support from the wall during movement outside said one or more subterranean locations, comprising: An enabling profile and a disabling profile spaced from each other and defining a profile pair associated with the wall defined by the tubular to define at least one desired subterranean location therebetween on the tubular such that an operating profile on the wall defined by the tubular and located within said profile pair, wherein said operating profile can be engaged for support by said collet assembly by virtue of movement enabled by said relatively moveable components, which comprises a sleeve and a mandrel, whereby said sleeve moves relatively to said mandrel independently and separately from said collet assembly before said collet assembly is located at said at least one operating profile and after the tool has passed said at least on enabling profile, said enabling profile reorienting said sleeve to permit relative axial movement between said mandrel and said collet assembly to permit support of said collet assembly when said at least one operating profile is engaged by said collet assembly whereupon release of said collet assembly from said at least one operating profile and further tool movement past an adjacent said at least one disabling profile, said sleeve is further relatively moved to prevent sufficient axial relative movement by said mandrel with respect to said collet assembly which would otherwise allow said collet assembly to find support in the tubular.
