Portable battery-powered safety lock
First Claim
1. A safety lock for firearms comprising:
- a backplate removably engageable with a frontplate when said backplate and said frontplate are applied to opposite sides of a trigger guard, said backplate and said frontplate each having an inward-facing surface and an outward-facing surface, said backplate further comprising;
a pin extending from said inward-facing surface of said backplate; and
said frontplate further comprising;
a pin-receiving orifice opening to said inward-facing surface of said frontplate at a position strategically located to complementarily receive said pin when said backplate and said frontplate are operably positioned on opposite sides of the trigger guard, said pin-receiving orifice extending into said frontplate a sufficient distance to effectively receive said pin;
locking means functionally disposed within said frontplate such that in operation said locking means securely engages said pin;
means for receiving information whereby an authorized user of the safety lock can be identified; and
electronically-powered means for analyzing the information to determine whether the information matches certain predetermined authorizing information, and if so, controlling the release of said locking means,wherein said locking means comprises a catch-plate comprising a rim which defines a pin-receiving aperture.

Abstract
The present invention relates to a safety lock that is attachable to the trigger of firearms to prevent accidental or unauthorized discharge. The safety lock comprises a pair of opposed plates, one having one or more pins extending normal therefrom, the other having a set of complementary pin-receiving orifices and housing a locking mechanism. The locking mechanism is controlled by a battery-powered microprocessor which not only receives and analyzes signals from a keypad, but detects unauthorized signals, controls deactivation of the keypad for preset period of time upon the detection of unauthorized user or improper code input, controls an audio alarm signal of the keypad by an unauthorized user, controls a low-battery warning signal, allows the authorized user to change the authorized signal, provides a method for disabling the locking system other than through the user determined code input at the keypad, monitors, controls, and provides for a low-battery voltage drain; and illuminates the keypad upon activation of the safety lock.
