Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
187 words
A universal wingnut wrench comprising: a body member having grip means for engaging the ears of a wingnut; magnet means for magnetically adhering said wingnut to said body member; and drive means for permitting torque to be applied to said body member so that said wingnut can be rotated with said wrench, said magnet means comprising: said body member having opposed positive and negative magnetic pole regions; said magnetic pole regions having symmetry about a longitudinal plane of said body member; said body member having a concavity at a first end; and said body member further comprising first and second and magnetically impermeable regions interposed between said pole regions adjacent said first end, said grip means comprising: said body member having first and second pairs of diametrically opposed pairs of slots at said first end; said body member having a first of each of said pairs of slots in said positive region adjacent a different one of said impermeable regions; and said body member further having a second of each of said pairs of slots in said negative region adjacent a different one of said impermeable regions.
