Claims
- 1. A pick resistant lock system for use within a housing having an interior end and an exterior end with an axial cylindrical bore and a plurality of radial bores spaced along the cylindrical bore and constituting a pin chamber, the radial bores having opened ends in communication with the axial bore, the system comprising in combination:a main cylinder having interior and exterior ends and a length there between, the main cylinder having radial bores alignable with the radial bores of the housing, a planar key way alignable with the radial bores of the housing when in the locked orientation, a pair of opposed flat regions running the length of the cylinder formed opposite the radial bores; a cylindrical casing being fitted about the main cylinder, the casing having apertures aligned with the radial bores of the main cylinder, the casing further including a slot running the length of the cylinder, the slot being oriented intermediate the opposed flat regions, the main cylinder and casing being rotatably secured within the axial cylindrical bore of the housing; a facing cylinder having an interior end and an exterior end the facing cylinder being rotatably secured within the bore of the housing such that the facing cylinder is axially aligned with the main cylinder, the facing cylinder also having an introductory key way alignable with the key way of the main cylinder for receiving a key.
- 2. A pick resistant lock system comprising in combination:a main cylinder having interior and exterior ends and a length there between, the main cylinder having radial bores and a planar key way, a pair of opposed flat regions running the length of the cylinder formed opposite the radial bores; a facing cylinder having an interior end and an exterior end in facing relation and axially aligned with the main cylinder, the facing cylinder also having an introductory key way alignable with the key way of the main cylinder for receiving a key.
- 3. The system as described in claim 2 further comprising:a cylindrical casing being fitted about the main cylinder, the casing having apertures aligned with the radial bores of the main cylinder, the casing further including a slot running the length of the cylinder, the slot being oriented intermediate the opposed flat regions.
- 4. The system as described in claim 3 wherein the opposed flat regions of the main cylinder are level with one another.
- 5. The system as described in claim 3 wherein the opposed flat regions of the main cylinder are not level with one another.
- 6. The system as described in claim 3 wherein the facing cylinder is rotatably positioned within the cylindrical casing.
