Abstract:
1. A rotating disk lock mechanism having a combination, said mechanism comprising: a lock housing; and a plurality of rotatable disks within said lock housing, each of said rotatable disks having a central aperture and a pair of opposed disk cam surfaces projecting into said central aperture, a peripheral shape of said central aperture and said disk cam surfaces defining a geometry of said central aperture, said rotatable disks being positioned in a stack such that said apertures form a keyway, at least one of said rotatable disks having a reduced central aperture with a diameter that is substantially less than a diameter of at least another one of said central apertures, said diameter being defined as a longest internal measurement of said aperture; wherein the geometry of the central aperture of the at least one rotatable disk having the reduced diameter central aperture is substantially identical to the geometry of at least another of the rotatable disks; and wherein said combination of said lock mechanism is determined in part by the number of said rotatable disks with reduced central apertures and their placement in said stack.
