Abstract
A self contained nut assembly to allow self nut locking and unlocking for use with a support member. The nut assembly comprises an upper nut containing a pronged locking sleeve. The nut and locking sleeve fit onto a threaded element projecting through a support member. The prongs of the locking sleeve are fashioned with feet for engagement with the support member to restrain selective movement therebetween. Arcuate portions of the sleeve are flared to fill openings in the nut thus locking the assembly in place.
Claims4
A locking nut assembly for attachment of a threaded element with at least one channel to a support member comprising:
- a nut for engagement with the threaded element, the nut being provided with at least one opening, a locking sleeve for insertion within the nut, the sleeve being formed with at least one prong in parallel alignment with the channel of the threaded element, the prong being formed with a foot adapted to interact with the support member to inhibit relative motion therebetween, and at least one portion of the inserted locking sleeve being deformed to fill the opening of the nut to restrain relative movement of the nut with respect to the threaded element.
