Abstract

Abstract Trigger safety device for firearms is provided having a pivotally mounted magnetically attractable bar positioned on the inside of the handle adjacent the trigger, with the bar directed toward the trigger or on the rear of the trigger, with the bar directed toward the handle. When the pin is oriented centrally, sufficient movement of the trigger is inhibited to prevent firing. The bar is mounted in a non-magnetizable casing. The user of the gun, by wearing a magnetic ring, displaces the bar from its central orientation and allows for sufficient movement of the trigger for firing.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 76 words
A safety device for preventing unauthorized firing of a weapon having a trigger and a handle comprising: a nonferruginous housing for mounting about the handle of said weapon; a magnetically attractable bar extending outwardly from said housing, pivotally mounted in said housing and balanced about the pivot; stop means for preventing said bar from pivoting beyond a predetermined arc; and magnetic means for maintaining said bar in a position subsequently in the center of said arc.
Claim 2
Dependent Claim 76 words
A safety device for preventing unauthorized firing of a weapon having a trigger and a handle comprising: a nonferruginous housing for mounting about the handle of said weapon; a magnetically attractable bar extending outwardly from said housing, pivotally mounted in said housing and balanced about the pivot; stop means for preventing said bar from pivoting beyond a predetermined arc; and magnetic means for maintaining said bar in a position subsequently in the center of said arc.
Claim 3
Dependent Claim 36 words
A device according to claim 1, wherein said magnetic means is said bar composed at least in part of a magnetic material, which is attracted by said trigger when said device is mounted on said handle.
Claim 4
Dependent Claim 26 words
A safety device according to claim 1, wherein said magnetic means is a magnetic member mounted symmetrically to said bar to the rear of said housing.
Claim 5
Dependent Claim 56 words
A firearm having a safety device according to claim 1, mounted about said handle in facing relationship with said trigger, wherein said trigger is notched on either side of the portion of said trigger in facing relationship with said bar, to allow for retraction of said trigger when said bar is pivoted from its central position.
Claim 6
Dependent Claim 12 words
A firearm according to claim 4, wherein said firearm is a pistol.
Claim 7
Dependent Claim 18 words
A firearm according to claim 5, wherein said pistol has an aluminum handle and said bar is magnetic.
Claim 8
Dependent Claim 12 words
A firearm according to claim 4, wherein said firearm is a rifle.
Claim 9
Dependent Claim 24 words
A device according to claim 1, wherein said housing is for mounting about the handle of said weapon in facing relation with said trigger.
Claim 10
Dependent Claim 79 words
A firearm with a ferruginous trigger and a nonferruginous handle having a pivotally mounted magnetic bar mounted in the handle of said firearm in proximity to the trigger with one end of said bar in facing relationship with the rear of said trigger, wherein said trigger is notched in the rear to leave a central projection which engages said bar upon retraction of said trigger; and stop means for restraining the movement of said bar in a predetermined arc.
Claim 11
Dependent Claim 79 words
A firearm with a ferruginous trigger and a nonferruginous handle having a pivotally mounted magnetic bar mounted in the handle of said firearm in proximity to the trigger with one end of said bar in facing relationship with the rear of said trigger, wherein said trigger is notched in the rear to leave a central projection which engages said bar upon retraction of said trigger; and stop means for restraining the movement of said bar in a predetermined arc.
Claim 12
Dependent Claim 75 words
A safety device preventing unauthorized firing of a weapon having a trigger and a handle comprising: a nonferruginous housing for mounting on the rear of the trigger; a magnetically attractable bar extending outwardly from said housing, pivotally mounted in said housing and balanced about the pivot; stop means for preventing said bar from pivoting beyond a predetermined arc; and magnetic means for maintaining said bar in a position substantially in the center of said arc.
Claim 13
Dependent Claim 75 words
A safety device preventing unauthorized firing of a weapon having a trigger and a handle comprising: a nonferruginous housing for mounting on the rear of the trigger; a magnetically attractable bar extending outwardly from said housing, pivotally mounted in said housing and balanced about the pivot; stop means for preventing said bar from pivoting beyond a predetermined arc; and magnetic means for maintaining said bar in a position substantially in the center of said arc.
Claim 14
Dependent Claim 24 words
A device according to claim 10, wherein said housing is for mounting on the rear of the trigger in facing relationship with said handle.
Claim 15
Dependent Claim 71 words
A safety device for preventing unauthorized firing of a weapon having a trigger and means confronting the trigger comprising: a magnetically attractable bar pivotally mounted with repect to said trigger confronting means and balanced about the pivot; stop means for preventing said bar from pivoting beyond a predetermined arc; and magnetic means for maintaining said bar in a position of said arc preventing the actuation of said trigger firing said weapon.
Claim 16
Dependent Claim 71 words
A safety device for preventing unauthorized firing of a weapon having a trigger and means confronting the trigger comprising: a magnetically attractable bar pivotally mounted with repect to said trigger confronting means and balanced about the pivot; stop means for preventing said bar from pivoting beyond a predetermined arc; and magnetic means for maintaining said bar in a position of said arc preventing the actuation of said trigger firing said weapon.
