Training Firearm

A trigger mechanism for a firearm, comprising:

• a subframe 34 having a first half and a second half;
• a break arm 44 having a first end 48 and pivotally coupled to the subframe 34 at a rotational portion 46, the break arm 44 movable between a rest position and an operating position;
• a trigger 60 pivotally coupled to the subframe 34 via a pin 140 and configured to rotate the break arm about the rotational portion 46 from the rest position toward the operating position upon rearward displacement of the trigger 60;
• a first spring 148 having a first arm 150 bearing upon a stop pin 144 fixed within the subframe 34 and a second arm 152 is in a surface defining a cavity 61 to bias the finger engagement surface 66 of the trigger 60 forward in the longitudinal direction, the first spring 148 configured to bias the trigger 60 in a forward direction;
• and
• a second spring 55 is rotationally mounted at a first location 57 on the subframe 34 and bearing upon the break arm to bias the break arm from an operating position back to a rest position,
• wherein a force applied to the finger engagement surface 66 of the trigger 60 in a longitudinal rearward direction rotates the trigger 60 about the pin 140 in an upward direction causing the first arm 150 of the first spring 148 to place pressure upon the stop pin 144 and the second arm 152 to compress and translate within the cavity 61 toward the first arm 150 until the break arm engagement surface 68 engages the trigger engagement surface 72 at the trigger-break arm engagement portion 73 to exert an upward repositioning force upon the break arm 44 separating the movable magnet 52 from the frame magnet 54, the first spring 148 storing rotational energy in the second arm 152 during the upward movement of the trigger 60 and releasing the stored rotational energy by resisting twisting forces to generate torque returning the second arm 152 to the initial position and the trigger 60 from the operating position to the rest position, and
• wherein the upward movement of the break arm 44 exerts pressure upon the second spring 55 until the first end 48 of the break arm 44 contacts the plurality of ribs 130 of the first half 36, the second spring 55 storing rotational energy during the upward movement of the break arm 44 and releasing the stored rotational energy by resisting twisting forces to generate torque returning to the initial position and the break arm 44 from the operating position to the rest position.

A method of operating a trigger mechanism for a firearm, comprising:

• biasing a trigger 60 coupled to a subframe 34 via a pin 140 toward a forward resting position via a first spring 148 operatively associated with the trigger 60;
• biasing a break arm 44 to a subframe 34 at a rotational portion 46 toward a rest position via a second spring 55 mounted to the subframe 34 at a first location 57 and bearing upon the break arm 44 at a point between the rotational portion 46 and a first end 48 of the break arm 44;
• applying a rearward displacement to the trigger 60 to rotate the trigger 60 about the pin 140 such that a break arm engagement surface 68 of the trigger 60, located rearward of the trigger rotation point 62, engages a trigger engagement surface 72 of the break arm 44 at a trigger-break arm engagement portion 73 and exerts an upward rotational force upon the break arm 44 to rotate the break arm 44 from the rest position to the operating position;
• and
• releasing the trigger 60 to allow the first spring 148 and the second spring 55 to independently cooperate to return the trigger 60 to the forward resting position and the break arm 44 to the rest position.
