US12410979 - Control element, breechblock stop lever, breechblock carrier, trigger, trigger assembly for an automatic weapon, and an automatic weapon equipped therewith

One example control element for controlling a breechblock stop lever that can move about a first axis of rotation, which can be moved between a standby position for releasing a breechblock carrier and a retaining position for retaining the breechblock carrier, includes a first arm ( 15 ) that can rotate about a second axis of rotation (B), a first control section on the first arm, the first control section including a first contact surface ( 11 a ) and a second contact surface ( 11 b ) facing away from the first contact surface ( 11 a ), which can be rotated about the second axis of rotation (B) for the control element ( 10 ) by a control curve ( 36, 37, 38 ) on the breechblock carrier ( 30 ); and a second control section ( 13 ) on the first arm, wherein the second control section can be controlled by a control surface ( 55 a ) on a trigger ( 50 ). Other examples are possible.

The patent describes a control element for an automatic weapon that includes a trigger assembly designed to pivot and interact with a breechblock stop lever and carrier. This assembly allows for precise control of the breechblock’s position through a series of interconnected components, enhancing the weapon’s functionality.

Claim 1

A trigger for controlling a control element in a trigger assembly for an automatic weapon, wherein the trigger comprises: a main body that can pivot about an axis of rotation; a projection extending axially away from the main body, a control surface that faces upward on the projections, wherein the control surface can be brought in contact with a corresponding control section on the control element for moving the control element form a first position to a second position, and a control edge on the projections, wherein the control edge is substantially parallel to the axis of rotation, which allows the control element to rotate about its own axis of rotation when the trigger is actuated. a main body that can pivot about an axis of rotation; a projection extending axially away from the main body, a control surface that faces upward on the projections, wherein the control surface can be brought in contact with a corresponding control section on the control element for moving the control element form a first position to a second position, and a control edge on the projections, wherein the control edge is substantially parallel to the axis of rotation, which allows the control element to rotate about its own axis of rotation when the trigger is actuated.
