High security lock mechanism

A locking mechanism adapted to be placed in locked and unlocked positions, comprising:

• a lock-bolt mounted for movement between locked and unlocked positions;
• a first engagement element having disengaged and engageable positions;
• an electric actuator having a rotatable output for driving the first engagement element to the engageable position thereof;
• a manually operated second engagement element which can be engaged with said first engagement element in said engageable position thereof;
• a lock-bolt drive mechanism operatively coupled between the lock-bolt and the first engagement element and operative to move said lock-bolt between said locked and unlocked positions;
• and
• a lost motion mechanism operatively coupled with said first engagement element and said lock-bolt drive mechanism, said lost motion mechanism allowing said electric actuator to turn said rotatable output and drive said first engagement element to the engageable position with a pulse of electricity;
• wherein said lost motion mechanism includes a pin contained in an elongate slot, said pin being located at one end of said slot when said first engagement element is in the disengaged position and located at an opposite end of said slot when said first engagement element is in the engageable position.

A self-powered electric lock comprising:

• a lock-bolt mounted for movement between locked and unlocked positions;
• a first engagement element having disengaged and engageable positions;
• an electric actuator having a movable output for driving said first engagement element to the engageable position thereof;
• a manually operated member operatively coupled to said first engagement element in the engageable position;
• a lock-bolt drive mechanism coupled to said lock-bolt and to said first engagement element when said first engagement element is in the engageable position, said lock-bolt movable relative to said lock-bolt drive mechanism and said first engagement element;
• an electronic data input device electrically coupled with said electric actuator to cause said movable output to drive said first engagement element to the engageable position thereof upon input of correct electronic input data to said electronic data input device;
• and
• an electricity generator operatively coupled to said manually operated member to generate electricity upon movement of said manually operated member, the electricity being used to power said electric actuator;
• wherein said manually operated member is usable by an operator to generate electricity and further usable to actuate said lock-bolt drive mechanism and retract said lock-bolt upon input of the correct electronic input data thereby placing said lock-bolt in the unlocked position.
