Abstract:
A self-powered electric lock comprising:a lock-bolt mounted for linear movement between locked and unlocked positions; a rotatable cam element having disengaged and engageable positions; an electric actuator having a rotatable output operative to rotate said rotatable cam element to the engageable position thereof; a lever arm pivotally coupled to said lock-bolt and operatively coupled to said rotatable cam element when said rotatable cam element is in the engageable position to thereby facilitate pivotal movement of said lever arm; an electronic combination number input device electrically coupled with said electric actuator to cause said rotatable output to rotate said rotatable cam element to the engageable position thereof upon input of a correct combination number code to said electronic combination number input device; and an electricity generator operatively coupled to said electric actuator to supply power for operating said electric actuator; a rotatable dial operatively coupled to said electronic combination number input device to allow input of the combination number code through rotation thereof and further coupleable to said lever arm when said rotatable cam element is in said engageable position; and a spring operatively coupled to said lever arm to pivot said lever arm into a position in which said lever arm is operatively coupled to said rotatable dial when said rotatable cam element is in said engageable position thereby allowing retraction of said lock-bolt by rotating said dial and pulling said lever arm.
