ABSTRACT:
A flexural pivot joint includes two pivoting members, which may be levers of a pivotal hand tool, and two substantially identical flexible blade elements, each substantially Z-shaped and having opposite ends respectively connected to the pivoting members. In particular, each blade end has an enlarged coupling portion adapted to be press-fitted in a groove which may be formed either directly in the lever member or in a bushing which is fixed to the lever member. Each bushing may be either a full cylinder or a split cylinder. In one embodiment the joint includes, in addition to the Z-shaped elements, two non-identical flexible elements, the four elements being equiangularly spaced. The grooves and coupling portions may be complementarily shaped, with each groove having a bead receivable in a recess in the coupling portion to inhibit relative rotation.
