(EN) PLIERS WITH FORCE AUGMENTATION AND SELF-ADJUSTMENT CAPABILITY
(FR) PINCE AVEC AUGMENTATION DE FORCE ET CAPACITE D'AUTO-REGLAGE
Abstract
(EN) Pliers with self-adjustment capability for applying a grasping force to a workpiece and for augmenting the grasping force applied to the workpiece which include a first plier member, a second plier member, a first pivot, a second pivot and a first biasing spring. The first plier member includes a handle portion, a jaw portion, an intermediate portion, a coupling interconnecting the handle portion of the first plier member to the intermediate portion of the first plier member, and locking device. The second plier member includes a handle portion, a jaw portion, and an intermediate portion disposed therebetween. The first pivot includes a shifting slot portion, a transitional portion, and a positioning slot portion with a generally arcuate portion formed in said intermediate portion of the first plier member.
(FR) Cette invention concerne des pinces auto-réglables permettant d'appliquer de manière croissante une force de serrage sur une pièce. Cette pince comprend un premier élément de pince, un second élément de pince, un premier pivot, un second pivot et un premier ressort de charge. Le premier élément de pince comporte une partie poignée, une partie mâchoire, une partie intermédiaire, un élément de liaison reliant la partie poignée du premier élément de pince à la partie intermédiaire de ce même élément de pince, et un dispositif de blocage. Le second élément de pince comprend une partie poignée et une partie mâchoire reliées l'une à l'autre par une partie intermédiaire. Le premier pivot comprend une partie avec fente de réglage, une partie de transition et une partie avec fente de positionnement de forme généralement cintrée dans la partie intermédiaire du premier élément de pince.
