Electronic and mechanical combination lock

A lock comprising:

• a housing having an opening for receiving a locking bolt being movable between a locked position and an unlocked position;
• a dual input dial having an electronic digital keypad for electronic entry of a combination and a mechanical dial for manual entry of a combination;
• a rotary actuator having a rotary output positioned within the housing and energizable between a locked condition for maintaining the locking bolt in the locked position and an unlocked condition that allows the locking bolt to move to the unlocked position;
• a cam wheel operably coupled to said housing, said cam wheel including a cam way;
• a bolt release lever moveably coupled to said housing, said bolt release lever having a nose portion engageable with said cam way and a locking bar;
• and
• a single armature post responsive to both an input of the electronic entry of the electronic combination input and the manual combination input of the manual combination, the single armature post coupled to the rotary actuator and rotatably responsive to the rotary output of the rotary actuator, said armature post including first and second outwardly extending flanges, said first outwardly extending flange normally biased in a blocking position by engaging a tip of the locking bolt to block said locking bolt from being moved to the unlocked position,
• wherein the electronic entry of the combination actuates the rotary actuator and causes said armature post to rotate by a predetermined amount in which the first outwardly extending flange rotatably moves from the blocking position to an unblocking position allowing said locking bolt to move into said unlocked position, and
• further wherein upon mechanical entry of the combination said nose portion engages said cam way and causes the locking bar to move downward by a predetermined amount thereby causing said second outwardly extending flange to rotatably move and cause said first outwardly extending flange to rotatably move from the blocking position to an unblocking position allowing said locking bolt to move into said unlocked position.
