Title
(EN) RATCHET WRENCH
(FR) CLE A CLIQUET
Abstract
(EN)
A ratchet wrench (10) is used to engage a first workpiece (14) to advance it about a second workpiece (16). The wrench (10) includes an annular driver member (20) having teeth (30) received in a first region (50) of a cavity (48). A pawl element (22) has shoulders (38, 40) that selectively engage sequential ones of the teeth (30), and nibs (42, 44) extend parallel to the pivotal axis of pawl element (22) which is disposed in a second region (52) of cavity (48). An elongated handle (26) has a bore (58) that communicates with cavity (48), and a drive shaft (28) is rotatably and slidably disposed in bore (58). The drive shaft may be linearly moved between a first position where rotation of the drive shaft (28) pivots the pawl element (22) and a second position where rotation of drive shaft (28) rotates the annular drive member (20).
(FR)
Une clé à cliquet (10) est utilisée pour faire avancer une première pièce (14) engagée dans celle-ci sur une seconde pièce (16). La clé (10) comporte une élément d'entraînement annulaire (20) doté de dents (30) venant se loger dans une première région (50) d'une cavité (48). Un élément cliquet (22) présente des épaulements (38, 40) qui viennent en prise avec les dents séquentielles (30) et des tenons (42, 44) s'étendent parallèlement à l'axe de pivot de l'élément cliquet (22) qui est placé dans la seconde région (52) de la cavité (48). Un manche allongé (26) présente un alésage (58) qui communique avec la cavité (48) et dans lequel un arbre de commande (28) est monté rotatif et coulissant. Cet arbre peut être déplacé de manière linéaire entre une première position dans laquelle sa rotation fait pivoter l'élément cliquet (22) et une seconde position dans laquelle sa rotation fait tourner l'élément d'entraînement annulaire (20).
