DEFINITION

Classification: 81/367

(under subclass 342) Tools including a handle-member, a handle-lever and an articulated jaw movable relative to the fixed, handle-member jaw, wherein the joint mechanism includes a toggle linkage.

(1) Note. See definition of the term "TOGGLE" under subclass 300.

(2) Note. Included herein and in the indented subclasses are those tools known in the art as vise-wrench, vise-grip, plier-wrench, locking plier or toggle-wrench type, wherein the jaws are clamped on the work after actuation without further effort by the operator. For other wrenches or pliers in which work is clamped between the jaws, see subclasses 318+ and 329+.

(3) Note. The toggle wrench mechanism in this and indented subclasses is replete with adjustment mechanisms, for which mechanism see subclasses 385+ as appropriate. The greatest number of these adjustments are to be found in subclasses 399+.

(4) Note. Included in this subclass are double toggle linkages which include at least three links (two of which links are connecting rods) and four pivots (one of which pivots is an outer pivot relative to one toggle and an intermediate pivot relative to the other toggle).
