Abstract:
1. An adjustable hand tool substantially embodying a wrench or pliers comprising: a fixed jaw member having a first compression surface disposed substantially in a first plane and having a terminal end; a support member having substantially parallelly accurate guide surfaces; said accurate guide surfaces of said support member having a forward side wall opposingly spaced parallelly apart from a rearward side wall; the support member having an interconnecting means for connecting said support member substantially integrally to said fixed jaw member at an area substantially where the accurate guide surfaces of said forward side wall and said rearward side wall are respectively; the support member extending substantially at a slanting angle to said first plane and extending substantially rearward from said first compression surface; a fixed lower handle having a forward section; the support member having said interconnecting means for connecting said support member substantially integrally to said forward section of said fixed lower handle at an area substantially where the accurate guide surfaces of the forward side wall and the rearward side wall are respectively; the fixed lower handle substantially extending rearward in a direction from said support member and extending substantially at an obtuse angle to said accurate guide surfaces respectively; a slidable jaw member having a second compression surface disposed substantially in a second plane; said slidable jaw member having a track follower means thereon; said track follower means for sliding said slidable jaw member substantially contiguous to said accurate guide surfaces of said support member; said slidable jaw member slidably securable to said support member; said second plane of said second compression surface substantially parallel to said first plane of said first compression surface; a movable upper handle having a forward surface end section means; said forward surface end section means for attaching said movable upper handle pivotably to said slidable jaw member; said movable upper handle pivotal attachment to said slidable jaw member comprising a forward axis; said forward axis disposed substantially parallel to said first plane of said first compression surface; the movable upper handle extending substantially rearward from said forward axis; said movable upper handle pivotably rotatable substantially around said forward axis; a toggle having an adjustable toggle mechanism; said adjustable toggle mechanism mountable substantially on said toggle and movable substantially fore or aft along said toggle thereby adjusting clamping force respectively; the toggle pivotably attachable to said movable upper handle; said toggle pivotal attachment to said movable upper handle comprising an axis means; the toggle substantially extending from said axis means and having an end pivotably attachable to said fixed lower handle; said toggle pivotal attachment to said fixed lower handle comprising a pivot axis; said axis means disposed substantially parallel to said forward axis and said pivot axis respectively; said toggle pivotably rotatable substantially around said axis means and said pivot axis; said toggle cooperatively correlated with said movable upper handle and with said track follower means for communicably manipulating said slidable jaw member towards said fixed jaw member or away from said fixed jaw member thereby always maintaining said second plane in substantial parallelism to said first plane respectively; and a release lever having a lever stop tip section means; said release lever pivotably attachable to said movable upper handle at said axis means; the release lever extending substantially from said axis means; said lever stop tip section means of said release lever pivotably rotatable substantially around said axis means; said release lever cooperatively correlated pivotally with said toggle and said movable upper handle for communicably manipulating the lever stop tip section means for locking or unlocking respectively said clamping force being transmittable at said obtuse angle to the accurate guide surfaces of said support member.
