Repositionable trigger system

Abstract

This invention replaces a stationary handgrip with a repositionable trigger system which allows the user to quickly reconfigure the trigger system to offset the trigger to either the right or to the left. This allows the user to protect his shooting hand from return fire from the enemy. A previous design from the inventor was a minimal exposure weapon which protected all of the shooter, with exception of the shooter's firing hand, by allowing the shooter from behind a wall or a corner. The present invention complements the previous invention as well as other weapons by protecting the shooter's hand.

1 ) A trigger system designed to be relocated from a normal position to protect the firing hand of the user from return fire by offsetting the handgrip to a position which could be shielded from hostile fire; said trigger system comprising: 
 a) said handgrip projecting from the inferior surface of the lower receiver of the weapon;    b) a trigger mount adapter connecting said trigger system to said lower receiver of said weapon;    c) a primary trigger interface control rod allowing control of primary trigger from a posterior location through an orifice in said trigger mount adapter;    d) a superior support arm connected to the inferior surface of said trigger mount adapter allowing bilateral rotation of said superior support arm about said trigger mount adapter said rotation is primarily in a perpendicular plane in relation to said lower receiver;    e) an inferior support arm connected to the inferior surface of said superior support arm allowing for rotational movement of said inferior support arm about said superior arm mainly in a perpendicular plane in respect to said lower receiver;    f) a secondary trigger mounted in said handgrip;    g) control linkages with associated pivot points connecting said secondary trigger to said primary trigger interface control rod allowing said weapon to be fired with said secondary trigger;    h) a means for securing said handgrip in position on said lower receiver when said weapon is to be fired with said primary trigger;    i) a means for securing said hand grip in position on said inferior support arm when said handgrip is positioned laterally in respect to said weapon when said weapon is to be fired by said secondary trigger preventing exposure to said return fire;    j) an improved spring and detent for said weapon safety lever which allows for said spring and said detent to be housed entirely in said lower receiver;    k) a retainer which mates between said lower receiver and said trigger mount adapter allowing for the repositioning of said handgrip while keeping captive said weapon safety lever, said spring and said detent;
