| 20100252385 | HAND TOOL WITH STEPLESS LOCKING MECHANISM - A ratchet mechanism contains a chamber defined by at least one gear surface, a rotating member positioned at least partially within the chamber, a gear member rotatably attached to the rotating member and positioned at least partially within the chamber, and a stop member engaging the rotating member, such that the rotating member and the stop member rotate in unison. The center of rotation of the gear member is offset from the center of rotation of the rotating member. The gear member includes a gear body having a plurality of gear teeth around an outer periphery thereof. At least a portion of the gear teeth engage the gear surface. The gear member can rotate freely in a first rotational direction, and a portion of the stop member abuts a portion of the gear member to prevent rotation of the gear member in a second, opposed rotational direction. | 10-07-2010 |
