Abstract:
A locknut wrench system for applying a proper rotational torque to a locknut during tightening and removal with the ability to fit around wires adjacent to the locknut and wherein the coupled locknut may be in a difficult-to-reach area comprising, in combination:a handle having a gripping end with a cylindrical gripping area, the gripping area having a first enlarged diameter, the handle also having a coupling end formed of spaced parallel arms with a slot therebetween with aligned apertures of a reduced diameter extending through the arms, the handle also having an intermediate portion between the gripping end and coupling end, the intermediate portion having a circular cross-sectional configuration of a second reduced diameter;a head in a generally cylindrical configuration having a lower end formed of a cylindrical wall, the lower end being formed with an upstanding recess for the receipt of a locknut, the recess having a lower cylindrical zone and an upper cone-shaped zone with two diametrically opposed pairs of downwardly extending legs each in a generally rectangular configuration extending downwardly from the cylindrical wall for removable coupling with respect to a locknut to be turned, the wall of the head being formed with an upwardly extending wire port in a generally rectangular configuration for the passage of wires therethrough, the head having an upper extent with a frusto-conical configuration region and with an upstanding projection adapted to fit within the slot of the handle and with an aperture of an enlarged diameter therethrough in axial alignment with the apertures of the handle;a cylindrical pivot pin extending through the apertures of the handle and coupled with respect thereto as well as extending through the aperture of the heads with the aperture of the head being of a slightly enlarged diameter to allow the pivoting of the head with respect to the pin and the handle; anda cover of an elastomeric material in a generally cylindrical configuration with an interior surface friction fit over the gripping area and with an exterior surface adapted to be grasped by the user during operation and use.
