Abstract

Abstract The lock slide is hinged to the safety bar and the combination lock is used to lock the lock slide against movement so as to prevent movement of the safety bar. This prevents the sear from pivoting away from the bolt. Upon release of the lock slide, the safety bar is free to be moved upon actuation of the grip safety if the thumb safety is off.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 89 words
In combination, a movably mounted sear for a firearm; a trigger mechanism movably mounted in independent relation to said sear for moving said sear in a predetermined path; a safety lock mechanism including a safety bar positioned in said path to prevent movement of said sear in said path and means for moving said safety bar out of said path; and a lock means connected to said safety bar to retain said safety bar in said path against the moving force of said means for moving said safety bar.
Claim 2
Dependent Claim 89 words
In combination, a movably mounted sear for a firearm; a trigger mechanism movably mounted in independent relation to said sear for moving said sear in a predetermined path; a safety lock mechanism including a safety bar positioned in said path to prevent movement of said sear in said path and means for moving said safety bar out of said path; and a lock means connected to said safety bar to retain said safety bar in said path against the moving force of said means for moving said safety bar.
Claim 3
Dependent Claim 34 words
The combination as set forth in claim 1 wherein said lock means includes a movably mounted lock slide connected to said safety bar and a lock for selectively securing said lock slide in place.
Claim 4
Dependent Claim 40 words
The combination as set forth in claim 2 wherein said lock slide is hingedly connected to said safety bar and said safety bar is pivotally mounted to pivot in a predetermined arcuate path away from said path of said sear.
Claim 5
Dependent Claim 45 words
The combination as set forth in claim 2 wherein said lock includes a pivotally mounted bar for securing one end of said lock slide in said lock and means for pivoting said bar from said lock slide to release said lock slide from said lock.

Dependent Claim 20 words
The combination as set forth in claim 1 wherein said means for moving said safety bar includes a grip safety.
Claim 7
Dependent Claim 30 words
The combination as set forth in claim 5 wherein said safety lock mechanism further includes a rotatable thumb safety selectively positioned in the path of movement of said safety bar.
Claim 8
Dependent Claim 105 words
In combination, a sear for a firearm; a trigger mechanism for moving said sear in a predetermined path; a safety lock mechanism including a safety bar positioned in said path to prevent movement of said sear in said path and means for moving said safety bar out of said path; and a lock means connected to said safety bar to retain said safety bar in said path against the moving force of said means for moving said safety bar, said lock means including a movably mounted lock slide connected to said safety bar and a combination lock for selectively securing said lock slide in place.
Claim 9
Dependent Claim 105 words
In combination, a sear for a firearm; a trigger mechanism for moving said sear in a predetermined path; a safety lock mechanism including a safety bar positioned in said path to prevent movement of said sear in said path and means for moving said safety bar out of said path; and a lock means connected to said safety bar to retain said safety bar in said path against the moving force of said means for moving said safety bar, said lock means including a movably mounted lock slide connected to said safety bar and a combination lock for selectively securing said lock slide in place.
Claim 10
Dependent Claim 73 words
In combination with a firearm having a bolt for firing a projectile and a pivotally mounted sear for selectively locking said bolt in a predetermined locked position, a trigger mechanism pivotally mounted in independent relation to said sear for moving said sear to unlock said bolt, and a safety lock mechanism for preventing movement of said sear; a lock means connected to said safety lock mechanism to selEctively prevent movement of said sear.
Claim 11
Dependent Claim 73 words
In combination with a firearm having a bolt for firing a projectile and a pivotally mounted sear for selectively locking said bolt in a predetermined locked position, a trigger mechanism pivotally mounted in independent relation to said sear for moving said sear to unlock said bolt, and a safety lock mechanism for preventing movement of said sear; a lock means connected to said safety lock mechanism to selEctively prevent movement of said sear.
Claim 12
Dependent Claim 45 words
The combination as set forth in claim 8 wherein said lock means includes a lock slide connected to said safety lock mechanism to prevent actuation thereof and a lock selectively connected to one end of said lock slide to prevent movement of said lock slide.
