CA 2326646

A ratcheting open-ended wrench (20) has a movable jaw (30) pivotally attached to a fixed jaw (32). The jaws (30, 32) define an opening (28) capable of receiving the hexagonal head (H) of a fastener such as a nut, bolt, hose fitting or pipe fitting. The fastener may be turned by moving the handle (22) of the wrench (20) back and forth without disengaging the fastener's head (H) from the opening (28). A stop (59) prevents the movable jaw (30) from moving in a way which would place excessive stresses on the movable jaw (30). An arc shaped bearing surface (62B) on the movable jaw is received in a mating bearing surface (62A) on the fixed jaw. The combination of the stop (59) and the mating bearing surfaces (62A, 62B) greatly reduces shear forces on the pivot (36). The point about which the movable jaw pivots is located forwardly relative to the opening (28).

L'invention concerne une clé à cliquet (20) à extrémité ouverte. Cette clé comporte un mors mobile (30) relié en vue de son pivotement à un mors fixe (32). Les mors (30, 32) définissent une ouverture (28) permettant de recevoir la tête héxagonale (H) d'un élément de fixation, tel qu'un écrou, un boulon, et des raccords de tuyaux ou de canalisation. Cet élément de fixation peut être tourné en déplaçant la poignée (22) de la clé (20) selon un mouvement alternatif sans retirer la tête (H) de l'élément de fixation de l'ouverture (28). Une butée (59) empêche le mors mobile (30) de se déplacer de telle sorte qu'il soit soumis à des contraintes excessives. Une surface d'appui en forme d'arc (62B) sur le mors mobile vient se loger dans une surface d'appui correspondante (62A) sur le mors fixe. La combinaison de la butée (59) et de la surface d'appui correspondante (62A, 62B) réduit fortement les forces de cisaillement sur le pivot (36). Le point autour duquel le mors mobile pivote est placé en avant par rapport à l'ouverture (28).
