Abstract

Trigger assemblies are provided for restraining a firing pin of a firearm on a selective basis. The triggers assemblies include a first and a second lever mounted for rotation within a housing. The first lever is configured to be rotated by the user, and rotation of the first lever imparts rotation to the second lever to initiate the discharge of the firearm. The trigger assemblies also include a safety mechanism having a safety lever that is movable between a first and a second angular position. The safety lever is configured to prevent movement of the first and second levers when the safety lever is in its first angular position, thereby preventing discharge of the firearm.

First claim

We claim:

1. A trigger assembly for restraining a firing pin of a firearm on a selective basis, comprising:
a housing;
a first lever mounted for rotation on the housing and movable between a first and a second angular position of the first lever;
a second lever mounted for rotation on the housing and movable between a first and a second angular position of the second lever, wherein the first lever is configured to move the second lever from the first to the second angular position of the second lever when the first lever moves from the first to the second angular position of the first lever, and
a first and a second adjustment screw mounted on the first lever; wherein the first lever is further configured to move the second lever from the first to the second angular position of the second lever via at least one of the first and the second adjustment screws; and the second lever and the second adjustment screw are configured so that a distance between an axis of rotation of the second lever and a point of contact between the second lever and the second adjustment screw decreases as the second lever rotates from the first angular position of the second lever and toward the second angular position of the second lever.

2. The trigger assembly of claim 1 , wherein:
the second lever is configured so that an end of the second lever contacts the second adjustment screw at a location on the second adjustment screw between the axis of rotation of the second lever and a centerline of the second adjustment screw;
the second adjustment screw has an end portion having a rounded upper surface; and
the second lever is configured so that the end of the second lever slides along the upper surface when the second lever rotates from the first angular position of the second lever and toward the second angular position of the second lever.

3. The trigger assembly of claim 2 , wherein:
the first lever has a first and a second portion;
the first and second adjustment screws are mounted on the second portion of the first lever;
the first portion of the first lever extends in a downward direction from the second portion of the first lever and has a substantially flat, forward-facing surface configured to act as a contact surface against which a user can exert pressure to rotate the first lever; and
the second adjustment screw is configured to be positioned so that a point of contact between the second lever and the second adjustment screw is lower, with respect to the downward direction, than the respective axes of rotation of the first and second levers when the first and second levers are in their respective first positions.

4. The trigger assembly of claim 3 , wherein the second adjustment screw is further configured to be positioned so that a lengthwise axis of the second lever is tilted downward when the second lever is in the first position of the second lever.

5. The trigger assembly of claim 4 , wherein the first adjustment screw is configured to be positioned so that the first adjustment screw comes into contact with the second lever when the lengthwise axis of the second lever is in an approximately level orientation with respect to the forward direction.

6. The trigger assembly of claim 1 , wherein the first lever is configured to rotate from the first to the second angular position of the first lever in a first direction; and the second lever is configured to rotate from the first to the second angular position of the second lever in a second direction, the second direction being opposite the first direction.

7. The trigger assembly of claim 1 , wherein the second lever is configured so that a ratio of an angular displacement of the second lever to an angular displacement of the first lever increases through at least an initial portion of the movement of the first lever from the first angular position to the second angular position of the first lever.

8. The trigger assembly of claim 2 , wherein the second lever is further configured so that the end of the second lever slides away from the centerline of the second adjustment screw when the second lever rotates from the first angular position of the second lever and toward the second angular position of the second lever.

9. The trigger assembly of claim 1 , wherein the first and the second adjustment screws are configured to be positioned so that the second adjustment screw contacts the second lever during at least an initial portion of the movement of the second lever from the first to the second angular position of the second lever; and the first adjustment screw contacts the second lever during at least a final portion of the movement of the second lever from the first to the second angular position of the second lever.

10. The trigger assembly of claim 1 , wherein the first lever is a trigger lever and the second lever is a re-cocking lever.

11. The trigger assembly of claim 1 , wherein the first adjustment screw is configured so that a position of the first adjustment screw in relation to the first lever is adjustable; and the second adjustment screw is configured so that a position of the second adjustment screw in relation to the first lever is adjustable.

12. A firearm comprising the trigger assembly of claim 1 .
