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 12):
A pair of scissors comprising:\n a lever-like first subassembly defining a first circular opening having a first diameter and a first annular surface surrounding said first opening; a lever-like second assembly defining a second circular opening having a diameter equal to said first diameter and a second annular surface surrounding said second opening; 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 top of said sleeve and defining an annular shoulder projecting radially from said sleeve and having an upper surface terminating in a peripheral rim and having an inward surface adjacent said bore and interrupted by a pair of opposed slots; \n a second hub nut comprising:\n a sleeve having an exterior cylindrical surface having a diameter substantially equal to said first opening diameter 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 lower surface terminating in a peripheral rim and having an inward surface adjacent said bore and interrupted by a pair of opposed slots, \n wherein said second hub nut threadably receives said first hub nut so that pawls engage said first hub nut serrated surface and a central throughbore traverses through said first and second hub nuts to secure said first subassembly to said second subassembly wherein said first hub nut annular shoulder engages said first annular surface and said second hub nut annular shoulder engages said second annular surface.
