Abstract

A wrench including a ratchet and first and second pawls in an end of the wrench. The ratchet having a first array of gripping members, the first pawl having a second array of gripping members, and the second pawl having a third array of gripping members. The second array of gripping members of the first pawl offset relative to the third array of gripping members of the second pawl, and the offset about doubling a pitch of the first array of gripping members of the ratchet to decrease a rotation of the wrench by about half. Each array of the first, second and third arrays of the gripping members having a first curvilinear surface in a first direction and a second curvilinear surface in a second direction different than the first direction to maximize a gripping surface area and increase an amount of torque the wrench may apply.

Dependent claims

A wrench for rotatably displacing a fitting, the wrench comprising:

a ratchet mechanism arranged in an end of the wrench, the ratchet mechanism including:
a ratchet disposed in a first receptacle in the end of the wrench, the ratchet being rotatably displaceable in the first receptacle and including an inside surface opposite an outside surface,
the inside surface of the ratchet being configured to interface with the fitting, and
the outside surface of the ratchet including a first array of gripping members;
a first pawl disposed in a second receptacle of the end of the wrench, the first pawl being displaceable in the second receptacle and including a second array of gripping members to cooperate with the first array of gripping members of the ratchet;
a second pawl disposed in a third receptacle of the end of the wrench, the second pawl being displaceable in the third receptacle and including a third array of gripping members to cooperate with the first array of gripping members of the ratchet;
and
wherein the second array of gripping members of the first pawl is offset relative to the third array of gripping members of the second pawl, the offset about doubling a gripping member ratchet pitch of the first array of gripping members of the ratchet.
