Abstract:
A method for opening magazines doors on a weapons storage facility, comprising the steps of:(a) rotating a handle for a security lock, mounted on one of said magazine doors, counterclockwise approximately ninety degrees, said handle being coupled to a shutter plate to rotate said shutter plate when said handle is rotated, said shutter plate when rotated exposing a first lock cylinder and a second lock cylinder mounted within said security lock; (b) inserting a first key into said first lock cylinder; (c) rotating said first key counterclockwise approximately one hundred eighty degrees after said first key is inserted into said first lock cylinder, said first lock cylinder being connected to a first eccentric cam wherein said first eccentric cam rotates when said first key rotates, said first eccentric cam engaging a first locking plate such that said first locking plate moves laterally when said eccentric cam rotates; (d) inserting a second key into said second lock cylinder; (e) rotating said second key counterclockwise approximately one hundred eighty degrees after said second key is inserted in said second lock cylinder, said second lock cylinder being connected to a second eccentric cam wherein said second eccentric cam rotates when said second key rotates, said second eccentric cam engaging a second locking plate such that said second locking plate moves laterally when said eccentric cam rotates, said first locking plate and said second locking plate holding an output shaft for said security lock in a fixed rotational position until said first key and said second key are rotated in a counterclockwise direction to move said first locking plate and said second locking plate away from said output shaft; (d) pushing said handle inward to a position where a clutch connected to said handle engages the output shaft for said security lock, said handle being released from said shutter plate when said handle is pushed inward; and (e) rotating said handle counterclockwise approximately ninety degrees which rotates the output shaft for said security lock allowing a user to open the magazine doors for said weapons storage facility.
