Multiple Slope or Multiple or Multiple Offset Tool Mechanism

摘要

Use of multiple-slope and/or multiple-offset mechanism or equivalent to address the issues with current mechanical clickers that have single-slope spring mechanism. The varying-slope can be a continuously varying-slope non-linear spring, or a combination of discretely varying multiple-slope springs. This invention is useful for clicker type torque wrenches, clicker type torque screw drivers, beam type torque wrenches, beam type torque screw drivers and shock absorbers. The present invention is equally applicable to clickers that click in both the CW (clockwise) and CCW (counterclockwise) directions or clickers that click only in one direction. The invention is generally characterized by placing a non-linear spring or combination of springs in the tool body to achieve multiple slope operation rather than using one single slope spring.

1. A method of improving performance of a torque tool comprising:
placing a multiple-slope or multiple-offset spring system in a torque tool barrel wherein said multiple-slope or multiple-offset spring system is adjustable to a specified target torque, said multiple-slope or multiple offset spring system causing said torque tool to release when said target torque is reached.
