Description: |
| This patent is a continuation of a portion divided from the application resulting in patent no. 6,889,579.
From BACKGROUND: "There exists a need in the art for an adjustable gripping tool which, as a result of manual operation, self-energizes the tool action, may be automatically sized and resized to engage a work piece, de-energizes upon release of actuation force, that has a broad range of dimensional capability, engages work pieces axially and radially and provides offsetting forces for stability in operation."
Abstract: "A self-energizing and de-energizing adjustable gripping tool for engaging a work piece to impart work thereto includes a first element and second element connected for relative movement. The second element includes an actuation portion having a plurality of slots. The first element includes gripping elements which are each associated with a force transfer element which engages one of the slots such that movement of the second element relative to the first element actuates the gripping elements to engage the work piece." The patent includes several dozen "figures" describing options for realization of the patented priciples.
"BIONIC GRIP" is an open-sided "pliers" type realization. |
