Abstract

Abstract The present invention relates to a folding utility tool having a plurality of tools which nest within the handle of the utility tool. The tool has a handle consisting of a first side and a second side spaced apart by a plurality of spacers. The area between the first side and the second side of the handle provides a first recess within the handle above the spacers and a second recess below the spacers. A pair of pivots, one on each of the handle, allow a plurality of tools to be pivoted from a nested position between the handles to an extended position beyond the handles. The tools may include such conventional devices as knife blades and screwdriver blades. At least one of the tools, however, is a pair of locking pliers having a first jaw and a second jaw pivotable about one of the pivot points. The first jaw is lockable in an extended position while the second jaw is adjustable and pivots about the same pivot point as the first jaw. An actuation lever and a reaction member provide an over-center mechanism to allow the pair of pliers to be locked in a given position with one jaw relative to the second jaw. The actuation lever has an adjustment mechanism which allows this relative position to be preadjusted for grasping various objects.

Claim 9
Dependent Claim 126 words
A folding utility tool as recited in claim 4 further comprising: a spring means for biasing said second jaw away from said first jaw; an actuation means pivotally attached to said second jaw; a reaction means pivotally attached to said handle for engaging said actuation means at an engagement point to create an over-center locking mechanism when said actuation means is depressed toward said handle to a locked position; an adjustment means for adjusting said engagement point along said actuation means for setting the distance between said first jaw and said second jaw when said actuation means is depressed fully toward said handle; and an unlocking means for bringing said actuation means and said reaction means back over-center to release said jaws from a locked position.
Claim 10
Dependent Claim 168 words
A folding utility tool comprising: a handle having a first side and a second side, said first side spaced apart from said second side; a first pivot and a second pivot, said first pivot and said second pivot attached to said first side and said second side of said handle; a plurality of tools, each of said tools pivotally attached to said first pivot and rotatable from a nested position between said first side of said handle and said second side of said handle to an extended position beyond said handle; a pair of locking pliers having a first jaw and a second jaw, said first jaw and said second jaw pivotally attached to said second pivot and rotatable from a nested position between said first side of said handle and said second side of said handle to an extended position beyond said handle; and an over-center means attached to at least one of said jaws for locking said jaws in a predetermined position relative to one another.
Claim 11
Dependent Claim 168 words
A folding utility tool comprising: a handle having a first side and a second side, said first side spaced apart from said second side; a first pivot and a second pivot, said first pivot and said second pivot attached to said first side and said second side of said handle; a plurality of tools, each of said tools pivotally attached to said first pivot and rotatable from a nested position between said first side of said handle and said second side of said handle to an extended position beyond said handle; a pair of locking pliers having a first jaw and a second jaw, said first jaw and said second jaw pivotally attached to said second pivot and rotatable from a nested position between said first side of said handle and said second side of said handle to an extended position beyond said handle; and an over-center means attached to at least one of said jaws for locking said jaws in a predetermined position relative to one another.
