Patent ID: 7862276

Claim:
An anti-unscrewing device for preventing the unscrewing of a ring nut having an engaging surface, comprising: a. a connecting portion rotatably-fixed, and attached to a body portion, said connecting portion forming an articulating portion and a pawl; b. said articulating portion biasing said pawl into engagement with the engaging surface, wherein said articulating portion: i. allows the ring nut to be rotated in a first direction by positioning the pawl so that the engaging surface of the ring nut pushes the pawl out of engagement with the engaging surface when the ring nut is rotated in the first direction; and ii. prevents the ring nut from being rotated in a second direction by positioning the pawl so that the pawl engages the engaging surface of the ring nut when the ring nut is rotated in the second direction, and wherein said connecting portion rotatably-fixed is configured to rotate about a first axis of rotation and the ring nut is configured to rotate about a second axis of rotation, wherein the first axis of rotation and second axis of rotation are substantially perpendicular to each other.
