Patent ID: 8850673

Claim:
A hook, comprising: a first member and a second member, the first and second members being pivotally connected about a pivot axis wherein the pivot axis is a fulcrum between a first portion and a second portion of each of the first and second members, the first portions of the first and second members defining a loop, the loop having an end opposite the pivot axis; a coil compression spring mounted between the second portions of the first and second members and biasing the first and second members to a closed position; a first contact surface carried by the second portion of the first member and a second contact surface carried by the second portion of the second member, the first and second contact surfaces being disposed opposite each other, the first and second contact surfaces being substantially the same width, the contact surfaces moving one of the first and second members to an open position within the loop as pressure is applied to the contact surfaces, the contact surfaces each having a width in a direction parallel to the pivot axis, wherein the sum of the widths is equal to at least half the distance from the pivot axis to the furthest linear distance on the inner perimeter of the loop and to at least three quarters of the distance between the contact surfaces when the first and second members are in the closed position.
