Abstract

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.

Claims (35)

1. A trigger assembly for an automatic weapon, comprising:

a 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, the control element including:

an arm that can rotate about a second axis of rotation;

a first control section on the arm, the first control section including a first contact surface and a second contact surface facing away from the first contact surface, which can be rotated about the second axis of rotation for the control element by a control curve on the breechblock carrier; and

a second control section on the arm, wherein the second control section can be controlled by a control surface on a trigger;

a breechblock stop lever that includes a stop arm for retaining the breechblock carrier, the breechblock stop lever including:

a first fastening arm extending substantially radially in relation to the first axis of rotation;

a second fastening arm extending substantially radially in relation to the first axis of rotation, wherein the first and second fastening arms are for receiving a control element that includes a second axis of rotation; and

a trigger including:

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 projection, wherein the control surface can be brought in contact with a corresponding control section on the control element for moving the control element from a first position to a second position, and

a control edge on the projection, 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;

wherein the control element can be controlled by a breechblock carrier that includes a control curve, such that the control element holds the breechblock stop lever in its standby position while the breechblock carrier moves forwards, and releases the breechblock stop lever in its retaining position while the breechblock carrier returns.

2. The trigger assembly according to claim 1 , wherein the control element is supported on the breechblock stop lever such that it can rotate about the second axis of rotation between two positions, and the first axis of rotation for the breechblock stop lever is connected to a non-rotating component, in particular a handle housing, such that the control element can rotate about its own axis of rotation and about the axis of rotation for the breechblock stop lever.

3. The trigger assembly according to claim 1 , wherein, when the control element is controlled by means of the control surface on the trigger, the control element rotates about the first axis of rotation for the breechblock stop lever.

4. The trigger assembly according to claim 1 , wherein the trigger assembly includes an element connected to a non-rotating component for guiding a third control section.

5. The trigger assembly according to claim 1 , wherein there are a continuous firing element and a safety, wherein the safety

secures the trigger in one setting,

releases the trigger and secures the continuous firing element in a second setting, and

releases both the trigger and the continuous firing element in a third setting.

6. An automatic weapon comprising:

a 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, the control element including:

an arm that can rotate about a second axis of rotation;

a first control section on the arm, the first control section including a first contact surface and a second contact surface facing away from the first contact surface, which can be rotated about the second axis of rotation for the control element by a control curve on the breechblock carrier; and

a second control section on the arm, wherein the second control section can be controlled by a control surface on a trigger;

a breechblock stop lever that includes a stop arm for retaining the breechblock carrier, the breechblock stop lever including:

a first fastening arm extending substantially radially in relation to the first axis of rotation;

a second fastening arm extending substantially radially in relation to the first axis of rotation, wherein the first and second fastening arms are for receiving a control element that includes a second axis of rotation; and

a trigger including:

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 projection, wherein the control surface can be brought in contact with a corresponding control section on the control element for moving the control element from a first position to a second position, and

a control edge on the projection, 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;

wherein the control element can be controlled by a breechblock carrier that includes a control curve, such that the control element holds the breechblock stop lever in its standby position while the breechblock carrier moves forwards, and releases the breechblock stop lever in its retaining position while the breechblock carrier returns.
