Abstract
Abstract A safety system for selectively disabling a firearm is disclosed. The firearm includes a mechanical linkage by which the firearm is fired by movement of a trigger, with the mechanical linkage including a link element. The link element is suitably mounted for movement between a position where the mechanical linkage is interrupted and a position where the mechanical linkage is functional. A link moving device for moving the link element between the interruped position and functional position is also provided with the link moving device normally biased to move the link element and hold the link element in the functional position. A remotely controlled actuating device for actuating the link moving device includes a transmitter designed to be carried by the operator of the firearm and a receiver adapted to be mounted in the handle of the firearm. The link member is conveniently a firing pin and/or a trigger bar. Once activated, the safety system is designed to be deactivated either by the absence of the activation signal or a new enabling signal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A safety system for selectively disabling a firearm comprising: a mechanical linkage by which the firearm is fired by movement of a trigger, said mechanical linkage including a link element; a link mounting means for mounting said link element for movement between a position wherein said mechanical linkage is interrupted and a position wherein said mechanical linkage is functional; a link moving means for moving said link element between the interrupted position and the functional position, said moving means being normally biased to move said link element to and hold said link element in the functional position; and a remotely controlled actuating means for actuating said link moving means including (a) a transmitter means for selectively transmitting a disabling signal, said transmitter means being designed to be carried by the operator of the firearm, and (b) a receiver means located adjacent said link moving means for receiving the signal from said transmitter means and for operating said link moving means.
Claim 2
Dependent Claim
160 words
A safety system for selectively disabling a firearm comprising: a mechanical linkage by which the firearm is fired by movement of a trigger, said mechanical linkage including a link element; a link mounting means for mounting said link element for movement between a position wherein said mechanical linkage is interrupted and a position wherein said mechanical linkage is functional; a link moving means for moving said link element between the interrupted position and the functional position, said moving means being normally biased to move said link element to and hold said link element in the functional position; and a remotely controlled actuating means for actuating said link moving means including (a) a transmitter means for selectively transmitting a disabling signal, said transmitter means being designed to be carried by the operator of the firearm, and (b) a receiver means located adjacent said link moving means for receiving the signal from said transmitter means and for operating said link moving means.
Claim 3
Dependent Claim
16 words
A safety system as claimed in claim 1 wherein said link moving means is a solenoid.
Claim 4
Dependent Claim
16 words
A safety system as claimed in claim 1 wherein said link member is a firing pin.
Claim 5
Dependent Claim
15 words
A safety system as claimed in claim 1 wherein said member is a trigger bar.
Claim 6
Dependent Claim
24 words
A safety system as claimed in claim 1 wherein said receiver means includes a cut-off switch for a battery which powers said receiver means.
Claim 7
Dependent Claim
47 words
A safety system as claimed in claim 1 wherein said actuating means includes a switch means which is easily actuated to activate said transmitter, said switch means including a keyed lock means for locking said transmitter in the activated condition until said keyed lock means is deactivated.
Claim 8
Dependent Claim
31 words
A safety system as claimed in claim 5 wherein said keyed lock means includes a plurality of push buttons which must be keyed in a predetermined sequence to deactivate said transmitter.
Claim 9
Dependent Claim
63 words
A safety system as claimed in claim 1 wherein after actuation of said receiver means, said link moving means is held in the position where said link element is in the interrupted position; wherein said receiver means further selectively transmits an enabling signal; and wherein said receiver means further receives said enabling signal and moves said link element back to the functional position.
Claim 10
Dependent Claim
37 words
A safety system as claimed in claim 8 wherein said transmitter means includes a plurality of push buttons which must be keyed in a predetermined sequence in order for the transmitter means to transmit the enabling signal.
