Abstract
An improved slide-fit nut is provided for rapid push-on mounting to a substantially seated position on a threaded bolt or the like. The slide-fit nut includes a plurality of threaded nut segments carried within a nut housing and adapted for radial expansion to accommodate push-on mounting onto a threaded bolt. A cap plate on the nut housing includes cam members for retaining the nut segments in threaded engagement with the bolt upon rotation of the nut in a tightening direction. When the nut is rotated in an opposite direction, the cam members displace the nut segments in a radially outward direction relative to the bolt, resulting in substantial disengagement of the nut segments to permit rapid pull-off removal of the nut from the bolt.
Claims11
A slide-fit nut for push-on mounting onto a threaded bolt, said nut comprising:
- nut housing means defining an open axial bore for reception of a bolt;
- and
- a plurality of part-cylindrical nut segments mounted within said nut housing means in a generally cylindrical array and cooperatively defining a female thread for threaded engagement with a bolt received through said axial bore, said nut segments being radially movable between a compressed position for threaded engagement with the bolt and a radially expanded position substantially disengaged from the bolt;
- said nut housing means and said nut segments including interengageable cam means for moving said nut segments toward said radially compressed position upon rotation of said nut housing means on the bolt in one direction, and for moving said nut segments toward said radially expanded position upon rotation of said nut housing means on the bolt in an opposite direction.
