Linear Firearm Trigger Mechanism for Consistent Pull

Instead of using a traditional pivot-based trigger that rotates, this patent inverts the approach by using a linearly-moving trigger that translates along a straight path. The trigger moves linearly from a first position to a second position, eliminating the rotational pivot point that causes rough or uneven trigger pulls. This inversion of the motion paradigm resolves the contradiction by achieving smooth, consistent trigger pulls while maintaining manufacturing feasibility through linear guide rails and simple translation mechanics.

This patent changes the spring configuration from torsion springs to linear compression springs. The compression springs provide a more consistent linear force throughout the trigger's linear motion path, unlike torsion springs which create variable force during rotation. The first compression spring biases the trigger between first and second positions, while the second compression spring biases the sear, creating predictable and consistent force requirements that eliminate unintentional firing while maintaining reliable return forces.

The trigger housing is segmented into functional components including guide rails that define the linear pathway, and distinct mounting areas for compression springs. The guide rails provide precise linear guidance for the trigger, while the segmented structure allows independent positioning of spring mechanisms. This segmentation resolves the contradiction by organizing complexity into manageable functional modules that collectively achieve precise linear trigger motion with improved repeatability.
