Abstract:
1. A safe comprising: a case having a door, said door having a first edge and a second edge opposite said first edge, a spring loaded hinge securing said first edge of said door to said case, a door loop secured to said door proximate said second edge of said door, a latch assembly mounted within said case having a primary latch arm, a secondary latch arm, and a latch plate, said primary latch arm rotatably secured to said latch plate and having a primary axis of rotation, a first spring arm, a retaining arm, a push arm, and a second spring arm opposite said first spring arm, said secondary latch arm rotatably secured to said latch plate and having a secondary axis of rotation, a standoff, a hook with a slot adapted to releasably receive said door loop, a notch adapted to receive said retaining arm of said primary latch arm in a locked position, and a stop adapted to encounter said retaining arm and prevent further rotation of said secondary latch arm about said secondary axis of rotation in a released position, a first primary latch arm spring having a first end secured to said latch plate and a second end biased against said first spring arm of said primary latch arm thereby applying a force against said first spring arm to rotate said primary latch arm about said primary axis of rotation, a second primary latch arm spring having a first end secured to said latch plate and a second end biased against said second spring arm of said primary latch arm thereby applying a force against said second spring arm to rotate said primary latch arm about said primary axis of rotation, a secondary latch arm spring having a first end secured to said latch plate and a second end biased against said standoff of said secondary latch arm thereby applying a force against said secondary latch arm to rotate said secondary latch arm about said secondary axis of rotation from said locked position to said released position, a motor having a shaft and mounted to said latch plate, a cam having a lobe and mounted to said shaft of said motor against said push arm of said primary latch arm, a biometric scanner configured to read and store fingerprint scan data, compare read fingerprint scan data with stored fingerprint scan data and generate a match signal, a microcontroller coupled to said biometric scanner and said motor, said microcontroller responsive to receiving said match signal from said biometric scanner to activate said motor to rotate said cam, and a power supply coupled to said motor, biometric scanner, and microcontroller, whereas said lobe of said cam engages said push arm to rotate said primary latch arm about said primary axis of rotation in a direction to compress said first primary latch arm spring and said second primary latch arm spring, and rotate said retaining arm away from said notch, whereas said secondary latch arm spring rotates said secondary latch arm about said secondary axis of rotation from said locked position to said released position, whereas said door loop is released from said slot and said door springs open by said spring loaded hinge, and whereas the bias forces of said first primary latch arm spring and said second primary latch arm spring are applied to said primary latch arm around said primary axis of rotation to prevent rotation of said primary latch arm by external forces.
