Abstract

A trigger is provided and may be pivotally connected to a frame at or near the top of the trigger. A sear transfer bar may be further provided and is pivotally connected to the frame. The pivot in the trigger is higher within the frame as compared to the pivot of the sear transfer bar. Two balls can be between the trigger and the sear transfer bar. The top of the sear transfer bar has a sear contact. Pulling the trigger in a first direction causes the trigger to rotate in a first direction. The sear transfer bar rotates under force of the trigger. The sear transfer bar and the trigger may rotate in opposite directions. The sear will drop when the sear contact of the transfer bar ceases engagement with the sear, causing the firearm to fire.

Claims

1. A trigger assembly comprising:

a frame;

a trigger pivotally connected to said frame at a trigger pivot;

said trigger has a trigger top and a trigger bottom, and said trigger is pivotally connected to said frame adjacent said trigger top;

a transfer bar pivotally connected to said frame, said transfer bar has a transfer bar top and a transfer bar bottom; and

a sear pivotally connected to said frame,

wherein;

said trigger engages said transfer bar at a location below said trigger pivot,

said transfer bar engages said sear to prevent said sear from dropping in a ready position, and

said transfer bar ceases engagement with said sear to allow said sear to drop under operation of said trigger wherein said trigger contacts said transfer bar at one or more locations between said transfer bar point of pivotal connection and said transfer bar top, whereby said trigger causes said transfer bar to rotate opposite the direction of rotation of said trigger.

2. The trigger assembly of claim 1 further comprising:

a first spacer block;

a second spacer block;

a first force member biasing said sear away from said first spacer block; and

a second force member biasing said transfer bar bottom away from said trigger.

3. The trigger assembly of claim 2 wherein:

said first force member is a first spring; and

said second force member is a second spring.

4. The trigger assembly of claim 1 wherein at least one round surface separates said trigger and said transfer bar.

5. The trigger assembly of claim 4 wherein said at least one round surface comprises at least one ball.

6. The trigger assembly of claim 5 where said at least one ball is partially retained within said trigger and partially extends outward there from.

7. The trigger assembly of claim 6 wherein said at least one ball comprises two balls.

8. The trigger assembly of claim 1 further comprising a safety, wherein said safety engages at least two components of the trigger assembly and prevents movement of the at least two components within said trigger assembly.

9. The trigger assembly of claim 8 wherein said at least two components consist of said transfer bar and said sear.

10. The trigger assembly of claim 9 wherein:

said safety further comprises a control arm, a first detent and a second detent; and

said trigger assembly comprises a safety ball for maintaining said safety in the selected position by being positioned in one of said first detent and said second detent under operation of said control arm.

11. A trigger assembly comprising:

a frame;

a trigger having a trigger top and a trigger bottom, said trigger being pivotally connected to said frame adjacent said trigger top;

a transfer bar having a transfer bar top and a transfer bar bottom, said transfer bar being pivotally connected to said frame between said transfer bar top and said transfer bar bottom;

a force component between said trigger and said transfer bar biasing said transfer bar bottom away from said trigger; and

a sear pivotally connected to said frame,

wherein;

said transfer bar engages said sear to prevent said sear from dropping in a ready position, and

rotation of said trigger overcomes the biasing of said force component and said trigger engages said transfer bar causing said transfer bar to rotate relative said frame such that said transfer bar bottom moves towards said trigger and said transfer bar ceases engagement with said sear to allow said sear to pivot relative said frame wherein said trigger contacts said transfer bar at one or more locations between said transfer bar point of pivotal connection and said transfer bar top, whereby said trigger causes said transfer bar to rotate opposite the direction of rotation of said trigger.

12. The trigger assembly of claim 11 further comprising:

a first spacer block;

a second spacer block;

a first force member biasing said sear away from said first spacer block; and

a second force member biasing said transfer bar bottom away from said trigger.

13. The trigger assembly of claim 11 wherein said trigger houses a first ball and a second ball, said first ball and said second ball projecting from said trigger and selectably contacting said transfer bar under rotation of said trigger.
