Abstract
A rotating disk lock mechanism that includes a lock housing containing a plurality of rotatable disks. Each disk having a central aperture and being positioned in a stack such that the central apertures form a keyway. At least one of the disks includes a reduced central aperture with a diameter that is substantially less than a diameter of at least another one of the central apertures. The combination of the lock mechanism is determined in part by the number of disks with reduced central apertures and their placement in the stack.
Claims20
A rotating disk lock mechanism having a combination, said mechanism comprising:
- a lock housing;
- a plurality of rotatable disks within said lock housing, each of said disks having a central aperture, said disks being positioned in a stack such that said apertures form a keyway, at least one of said 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;
- and
- wherein said combination of said lock mechanism is determined in part by the number of said disks with reduced central apertures and their placement in said stack.
A lock system comprising:
- a rotating disk lock mechanism having a housing that includes a plurality of rotatable disks positioned in a stack within said housing, each of said disks having a central aperture that, when positioned in said stack, form a keyway, at least one of said central apertures having a reduced diameter that is substantially less than a diameter of at least another one of said central apertures;
- a key having a plurality of key cam sections that engage and rotate said plurality of rotatable disks to lock or unlock said lock mechanism;
- and
- wherein at least one of said key cam sections has a reduced profile that engages said reduced diameter central aperture and rotates said disk having said reduced diameter central aperture.
A method of creating lock combinations in a rotating disk barrel lock that includes a plurality of rotatable combination disks, each of said disks having a central aperture with cam surfaces, said method comprising the steps of:
- selecting a plurality of rotatable combination disks, each of said combination disks including a central aperture having a first diameter;
- and
- selecting at least one rotatable combination disk including a central aperture having a second diameter that it substantially less than said first diameter.
