DEVICE TO SECURE HAND-HELD FIREARMS

SECURITE POUR ARME DE POING

English Abstract

Mechanic gun lock with electronic voice and word recognition and microphone,
comprising of a mechanical, two part section with a lockable body which is
fastened in place around the trigger of a handheld fire armwith a locking
mechanism in place. For the release of the two parts an electronic switch is
designed. This loosens the locking mechanism if the electronic voice processor
recognizes a prior safed code word, and voice from a certain person as
correct. The gun lock works with a low voltage for example a battery.

French Abstract

La présente invention concerne un dispositif de verrouillage mécanique pour armes de poing, faisant intervenir un processeur de reconnaissance vocale et un microphone. Ce verrouillage se compose d'un corps en deux parties qui se réunissent mécaniquement de façon à se refermer autour de la gachette de détente de l'arme de poing. Pour réaliser ce verrouillage, on réunit les deux parties en exerçant sur elles une pression, ce qui vient enclencher un verrou sous charge de ressort. La séparation des deux parties du dispositif de verrouillage est commandée par un commutateur électromagnétique. Ce dernier libère le verrou sous charge de ressort dès qu'un processeur électronique de reconnaissance vocale associé reconnaît que le mot de code prononcé par une personne est conforme avec celui qui est mémorisé. Ce dispositif de verrouillage pour arme de poing fonctionne avec une source électrique basse tensoin, en l'occurrence une pile électrique.

Claims

Claims
01. Device to secure hand held fire arms characterized by two shells, the
trigger (7) of a small are (1) overlapping formation, whereby both shells
(11, 16) are connectable with one another, as well as through ~ the two
shells in connection with one another connecting locking mechanism (12)
whereby one of the shells (11, 16) one by means of a lock activated
locking bolt (12.1) and the other of the shells (16, 11) one with the locking
bolt (12.1) interacting locking handle (17) exhibits.
02. Device according to claim 1 through that characterized, that both shells
(11, 16) are to open linked together.
03. Device according to claim 1 or 2 through that characterized that the
locking mechanism (12) is formed in a manner that it blocks the activation
of the trigger (~) with a sustain mold-lock on the trigger level (~) to apply
up against.
04. Device according to one of the claims 1 through 3, through that
characterized that the locking mechanism exhibits an electronic which is
programmed for the detection of speech recognition, which is equipped
with a minimum of one micro processor and a program and data memory.
8

5. Device according to claim 4 characterized that in one shell a microphone
for
entry of a code word is positioned.
6. Device according to claim 5 characterized that in one of the shells for the
input of a key word through the microphone a switch is equipped.
