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.

A swing bolt lock includes a swing post, a cam dog, and an electric device cooperative with a lock bolt. The electric device includes a motor, a slider connected to a rotating shaft of the motor. Without an unlock authorization, the slider is situated in the space at an end of a sliding slot and abutted against the cam dog to prevent the cam dog from moving towards the space at the end of the sliding slot, so as to prevent the lock bolt from entering into the lock housing. With an unlock authorization, the slider is driven by the motor and released from the abutment of the cam dog, and the cam dog is driven by the lock bolt and swing post to enter into the space at the end of the sliding slot so as to release the locking of the lock bolt from turning into the lock housing.

The present invention relates to a safety locking mechanism for a lockset having a cover plate, a support plate, and a lock body. The safety locking mechanism includes a locking push rod having a direction-limiting shaft and a cylindrical rod, a locking stopper, and a locking compression spring. The direction-limiting shaft is mounted at one end of the cylindrical rod and the other end of the cylindrical rod passes through the support plate and presses against the cover plate. The locking stopper is rotatably mounted on the cylindrical rod and has a front end and a back end being close against the support plate and the lock body respectively. The lock body is provided with a direction-limiting groove. The direction-limiting shaft is mounted in the direction-limiting groove. The locking compression spring is mounted between the direction-limiting shaft and a bottom end of the direction-limiting groove in a compressed manner.

METHOD FOR BANK EQUIPMENT REINFORCEMENT AND FIXATION THROUGH AN ANCHORAGE BASE, which is intended for the reinforcement and clamping of ATMS and Cash Dispensers type equipment, being characterized by envisioning the installation of jackets (1) in the equipment, being that the jackets (1) are protective plates installed in the safes, being basically composed by a box (2) made of metal plate, having material layers in its internal part having the objective to provide resistance against burglary, being the first layer of material contained in the box (2) forming the jacket (1) a chemical compound (3) providing resistance against the effects of a blow torch while the second layer is preferably produced with concrete (4), providing mechanical strength to the parts; the chemical protection which constitutes the layer (3) is, essentially, a flammable compound, preferably containing bitumen, pitch and sulfur at duly specified layer amounts and thicknesses; in its turn, layer (4), which constitutes the mechanical protection is preferably obtained with reinforced concrete containing cement, aluminum oxide with a number of granulations and steel stretched wires, at the specified amounts.

An apparatus for preventing unwanted opening of a locked enclosure. The enclosure includes a lock, a door and a door bolt. The door is openable when the door bolt is retracted from a structure surrounding the enclosure. The apparatus includes a frangible guard plate, and an arm coupled to the guard plate by a spring. The arm is maintained in a first position under a bias of the spring. When the guard plate is fractured, the arm is free to move from the first position into a second position. The arm is positioned to engage the door bolt in the second position, thereby preventing retraction of the door bolt.

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.

A safe door includes: a body part; a locking part configured to be in one of a locked state in which the lock part protrudes from the body part and an open state in which the locking part is deviated from the locked state; and a relocking unit configured to restrict a movement of the locking part. The relocking unit includes: an actuator; a relocking bracket provided in a bracket form covering an outer shape of the actuator and movable by operation of the actuator; and a relocking member mounted on an end of the relocking bracket and configured to restrain the locking part by movement of the relocking bracket.
