Abstract:
1. A gripping device comprising: a first arm having a front section and a rear section, said front and said rear section being pivotally connected to one another; a second arm having a front section and a rear section, said front and said rear section being pivotally connected to one another; a first fulcrum for pivoting said first arm front section with respect to said second arm front section; a second fulcrum for pivoting said first arm rear section with respect to said second arm rear section; wherein said first arm front section and said second arm front section providing opposing gripping surfaces for said device; a third fulcrum for pivoting a pair of positioning members with respect to one another, said pair of positioning members positioned between said first arm rear section and said second arm rear section, wherein a first positioning member of said pair of positioning members is pivotally attached to said first arm rear section at a first positioning pivot point and wherein a second positioning member of said pair of positioning members is pivotally attached to said second arm rear section at a second positioning pivot point, and wherein said first positioning member and said second positioning member are pivotally connected at said third fulcrum; wherein portions of said arms and said positioning members forming a linkage mechanism for moving said first arm with respect to said second arm, said positioning mechanism comprising a pair of laterally arranged linkages that are pivotally and laterally connected to one another at said second fulcrum, wherein a first linkage of said pair of laterally arranged linkages begins at said third fulcrum and terminates at said second fulcrum, and wherein a second linkages of said pair of laterally arranged linkages begins at said first fulcrum and terminates at said second fulcrum; and an adjusting means for adjusting the distance between said gripping surfaces.
