Title: (DE) RATSCHENSCHRAUBENZIEHER UND HERSTELLUNGSVERFAHREN DAFÜR
(EN) RATCHET DRIVER AND METHOD OF MAKING SAME
(FR) MANDRIN A CLIQUET ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN) A ratcheting driver (10) configured to rotationally drive an item or work piece is provided. The driver includes a handle (11) and pivotal pawls (23, 24) engageable with a driven gear (17) and capable of ratcheting and driving in both rotational directions. The handle and pawls have mating matched surfaces for full and flush overlying contact therebetween. A cap (26) that is rotatable relative to the handle and that has a web for pivoting the pawls out of engagement with the gear is also provided. In addition, a stop (63) is included. The stop is configured to assure that only a correct direction of rotation of the cap is available when assembling. Also, a method of arranging the driver is provided.
(FR) L'invention concerne un mandrin à cliquet, configuré pour entraîner en rotation un article ou pièce à travailler, qui comprend une poignée et des cliquets pivotants pouvant entrer en prise avec une roue menée et encliqueter et entraîner dans les deux sens de rotation. La poignée et les cliquets présentent des surfaces homologues appariées assurant entre elles un contact sus-jacent affleurant. On décrit une coiffe articulée à la poignée et comprenant une âme qui fait pivoter les cliquets et les dégage de la roue. On décrit également une butée configurée pour imposer le seul le sens de rotation approprié de la coiffe lors du montage. On décrit en outre un procédé de montage du mandrin.
