LOCKING FASTENER WITH DEFLECTABLE LOCK

摘要

A fastener with a locking mechanism includes an elongated bolt member with threaded segment defining a banking feature and generally planar surfaces, a nut member, a washer member, and a lock member. The nut member has a threaded bore for cooperating with the threaded segment of the bolt member and a peripheral edge with a flat side defining an axial slot.;The washer member has a central bore with a banking portion that complements the banking feature of the bolt member such that, when the threaded segment is inserted in the central bore, the washer member moves axially and is rotatably fixed relative to the bolt member. The washer member has an axially projecting circumferential wall with radially inward facing engagement teeth for intermeshing with teeth of the lock member. The lock member has a spring finger upstanding from the annular body that is received in the axial of the nut member for fixing the lock member in rotation relative the nut member.

1. A fastener with a locking mechanism, comprising:
a) an elongated bolt member having a threaded segment with a banking feature and generally planar surfaces extending axially along the threaded segment; b) a nut member having a threaded bore extending therethrough for cooperating with the threaded segment of the bolt member, the nut member having a peripheral edge with at least one flat side with an axial slot therein; c) a washer member having a central bore formed therethrough with a banking portion that complements the banking feature of the bolt member so that, when the threaded segment of the bolt member is inserted in the central bore of the washer member, the washer member moves axially along the threaded segment and is fixed in rotation relative to the bolt member, the washer member further having an axially projecting circumferential wall with radially inward facing engagement teeth; and d) a lock member having an annular body and at least one upstanding spring finger that is angled radially inward from the annular body, the annular body of the lock member having at least one tooth disposed circumferentially adjacent to the at least one spring finger of the lock member and extending radially outward from the annular body of lock member.
