Embodiment Construction

[0032] Basic Terminology. Certain expressions are explained in alphabetical order: “fitting” refers to a fitting (alternatively, “outer fitting”) having a larger inner diameter in relation to a pipe's smaller outer diameter and capable of enclosing therein the pipe, at least partially; “interlocked combination” refers to a pipe-fitting combination that has been positioned and interlocked; “interlocking” refers to using an indentation vise-wrench with a positioned combination to create an interlocking junction which thereby interlocks the pipe-fitting combination into a permanent, definitive position in which neither the pipe nor are movable; “pipe” refers to a pipe (alternatively, “inner pipe”) having a smaller outer diameter in relation to a fitting's larger inner diameter and capable of being enclosed by the fitting, at least partially; “pipe-fitting combination” refers to any particular combination of a given pipe and a given fitting suitable for interlocking; “positioned combina...

Abstract

The invention relates to indentation vise-wrenches; in use, interlocking pushed-out areas (“exdentations”)/pushed-in areas (“indentations”) of a fitting's inner surface/a pipe's outer surface are created by indenting units at indentation vise-wrenches' jaws. Neither pipes nor fittings of interlocked pipe-fitting combinations will move with respect to each other; even after total separation between the indentation vise-wrench and the interlocked combination. Embodiments include a tool comprising an indentation vise wrench; a tool kit comprising a set having at least two indentation vise-wrenches; a process comprising making indentation vise-wrenches; a process of interlocking pipe-fitting combinations; etc.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] Main Idea. The invention is generally directed to hand tools commonly called vise-wrenches (sometimes known as locking pliers, lockjaw pliers, plier-wrenches, toggle-wrenches, vise-grips, etc.) generally having a pair of two jaws (stationary / movable), a pair of two handles (stationary / movable), and mechanisms for locking, releasing, and adjusting (e.g., a torsion spring, a toggle link, a toggle release lever, a threaded adjusting screw, etc.). Generally, the pair of two jaws and the pair of two handles are relatively movable; in use, manipulative movement of the handles with respect to each other effects relative movement of the jaws, and in turn, the jaws can fully-engage with or fully-disengage from articles, items, or objects (“work”) between the jaws. With this background and in more detail, the invention relates to indentation vise-wrenches with indenting units at jaws which can interlock pipe-fitting combinati...
