Abstract: A multi-drawer file cabinet having an upper cabinet that may be stacked on top of a lower file cabinet is provided. The lower cabinet includes a top surface having a peripheral edge with a first perimeter. The upper cabinet includes a base with a sidewall. The sidewall has a peripheral edge with a second perimeter. The second perimeter is larger than the first perimeter so that the sidewall fits around the peripheral edge of the top surface of the first cabinet. The cabinets include an extendable drawer assembly having a pair of slide members slidably positioned between a pair of outer tracks formed in a casing and tracks formed in a drawer frame. Furthermore, a locking assembly is associated with a recess in the casing and a ledge of a drawer head to allow the drawer assembly to remain in a locked position even if the cabinet sustains fire damage.

Abstract: An internal hinge (34) for a fire-resistant enclosure is provided. The internal hinge includes a cabinet end (36) and a door end (38). The cabinet end is pivotally coupled with a bracket (64) mounted on the enclosure and the door end is fixedly coupled with a door (32) of the enclosure. The hinge includes first, second, third, and fourth segments (72, 74, 76, 78). The first segment extends linearly from the cabinet end of the hinge. The second segment extends from the first segment in a generally curved path wrapping around the cabinet end approximately 90 degrees. The third segment extends linearly from the second segment and at an angle relative to the first segment The fourth segment extends linearly from the third segment to the door end of the hinge and is perpendicular to the first segment. The internal hinge of the present invention allows the door of the enclosure to open approximately 147 degrees.

Abstract: A lock interface for a biometric lock is provided. The lock interface includes a body, a biometric sensor, and a biometric alignment feature. The biometric sensor is mounted to the body for reading a unique identifying characteristic of an individual. The alignment feature is associated with the sensor to assist a user in properly positioning the unique identifying characteristic with respect to the sensor. The present invention also includes a method for unlocking a safe using a biometric lock. The method comprises initiating the biometric lock by contacting the lock interface, recognizing a visual cue that indicates that a unique identifying characteristic is to be entered using the sensor, and entering the unique identifying characteristic feature using the sensor. The entered unique identifying characteristic is compared with a stored unique identifying characteristic, and the safe is unlocked if the unique identifying characteristic matches the stored unique identifying characteristic.
