Abstract:
A low-friction hub assembly for pivotally connecting a pair of scissors employs a pair of cooperative hub nuts. A first hub nut has an exterior threaded surface which threadably engages with an interior threaded surface of the second hub nut. Each of the hub nuts has annular shoulders which engage against opposed annular surfaces of surrounding aligned pivot openings of the scissors. A pair or opposed pawls engages a serrated surface to lock the subassembly. A throughbore extends through the pivot assembly.

Claim (Index 1):
A low friction hub for pivotally connecting a pair of scissors comprising:\n a first hub nut comprising:\n a sleeve defining a cylindrical bore and having an exterior threaded surface and a circumferential serrated surface; \n a head integrally extending at a bottom of said sleeve and defining an annular shoulder projecting radially from said sleeve and having a tapered upper surface terminating in a peripheral rim and having an inwardly angled surface adjacent said bore and interrupted by a pair of opposed slots; \n a second hub nut comprising:\n a sleeve having a cylindrical exterior surface and defining an interior threaded bore and opposed axially projecting pawls; \n a head integrally extending at a bottom of said sleeve and defining an annular shoulder projecting radially from said sleeve and having a tapered lower surface terminating in a peripheral rim and having an inwardly angled surface adjacent said threaded bore and interrupted by a pair of opposed slots; \n wherein said second hub nut threadably receives said first hub nut so that said pawls engage said first hub nut serrated surface and a central throughbore traverses through said first and second hub nuts.
