Lockable nut system
First Claim
1. A lockable nut system for threaded steel bar having a non-circular cross-sectional shape with at least one planar side wall, said lockable nut system comprising:
- a screw threaded nut rotatably engageable on said threaded steel bar; and
a tubular locking member slidably engageable on said threaded steel bar, said locking member being adapted in use to resist rotation about said bar, said nut and said locking member being axially engageable whereby in use said locking member resists rotation in at least one direction of said nut on said bar, and further wherein said locking member has a non-circular cross-section aperture generally complementary to said non-circular cross-sectional shape of said bar.

Abstract
A lockable nut system for use with threaded steel bar which includes a screw threaded nut for engagement with the threaded steel bar and a locking member which is slidably engageable with the bar. The locking member is adapted to resist rotation about the bar and is also axially engageable with the nut to prevent rotation of the nut. The locking member has one or more fingers to engage the nut with an end of the finger being displaced to engage the nut as a result of deformation of a finger actuating tab or a dished body of the locking member. The locking member may engage the bar by displacement of an end of at least one tongue as a result of deformation of a tongue actuating tab during compression between the nut and a second structure.

11. A lockable nut system for threaded steel bar having a non-circular cross-sectional shape, said lockable nut system comprising:
-
a screw threaded nut rotatably engageable on said threaded steel bar; and
a locking member slidably engageable on said threaded steel bar, said locking member comprising a generally disc shaped body having a cross sectional aperture therein, said aperture having a shape generally complementing to the cross section shape of the bar to resist rotation about said bar, said nut and said locking member being axially engageably whereby in use said locking member resists rotation in at least one direction of said nut on said bar, and further wherein said locking member comprises a generally toroidal body, said body comprising at least one axially projecting finger, at least one finger actuating tab wherein in use deformation of the at least one finger actuating tab from a first position inclined to a transverse plane of the body to a second position substantially co-planar with the transverse plane of the disc urges an end of said at least one axially projecting finger inwardly to engage an adjacent outer end of a nut to resist rotation thereof. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 22, 23)

24. A lockable nut system for threaded steel bar having a non-circular cross-sectional shape with at least one planar side wall, said lockable nut system comprising:
-
a screw threaded nut rotatably engageable on said threaded steel bar, said nu including a coaxially aligned outwardly divergent frusto conical engagement surface at one end thereof; and
,a locking member slidably engageable on said threaded steel bar, said locking member being engageable with said at least one planar side wall of said bar to resist relative rotation therebetween, said locking member including at lest one nut engaging finger engageable against said frusto conical engagement surface of said nut to resist axial separation between said nut and said locking member when engaged. - View Dependent Claims (25, 26, 27, 28, 29)
