Abstract:
1. An articulating wrench for engaging and turning a fastener, comprising a handle with first and second ends, with first and second opposed edges, with first and second opposed faces, and with a longitudinal axis, said handle having a shallow generally U-shaped depression extending into said handle from said first end between said edges so as to form a pair of bordering edges in opposed relation on either side of said depression, and said handle having a pair of coaxially aligned handle pin apertures, each of said handle pin apertures extending through one of said bordering edges perpendicular to said longitudinal axis of said handle; and a wrench head formed as a generally planar body having an upper face and a lower face, with a fastener engaging aperture formed in said body, said fastener engaging aperture surrounded by a generally annular rim having an outer edge at the periphery of said body and an inner edge defining said fastener engaging aperture, said rim having a pair of cut-outs extending inwardly from said outer edge of said rim, said cut-outs defining a boss therebetween, said boss having an outer edge and said boss being penetrated by a pivot pin aperture, said wrench head partially nested into said handle with said boss extending into said depression in said handle with said bordering edges extending into said cutouts and said handle pin apertures coaxially aligned with said pin aperture in said boss, and said wrench head pivotally connected to said handle by a pivot pin extending through said coaxially aligned apertures, said pivot pin having a longitudinal axis and a longitudinal center point on said longitudinal axis, with the distance between said center point on said longitudinal axis of said pivot pin and the point of said fastener engaging aperture lying closest to said center point on said longitudinal axis of said pivot pin being less than the minimum distance between said center point on said longitudinal axis of said pivot pin and said upper face of said handle and less than the minimum distance between said center point on said longitudinal axis of said pivot pin and said lower face of said handle.
