  • Device and methods for preventing unwanted access to a locked enclosure
    Patent number: 10550604
    Abstract: A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.
