US12716672 - Machine gun trigger assembly

A trigger lever assembly includes a link rotatable between a first position and a second position. The link has a first leg extending from an axis of rotation to a first end portion and a second leg extending from the axis of rotation to a second end portion. A trigger lever is mounted to the first end portion of the link and is rotatable between a blocked position and an unblocked position. The trigger lever is biased toward the blocked position. In the blocked position, a second end portion of the trigger lever contacts a first protrusion on the link. On the other hand, when the trigger lever is in the unblocked position, the second end portion of the trigger lever abuts a second protrusion on the link. The assembly can be part of a spade grip assembly or part of a complete machine gun.

In this assembly, the trigger lever’s movement is restricted by protrusions on the link, allowing for either a blocked or unblocked firing state.

Claim 1

1 . A trigger lever assembly comprising: a link rotatable about an axis of rotation between a first position and a second position, the link having a first leg extending from the axis of rotation to a first end portion and a second leg extending from the axis of rotation to a second end portion; and a trigger lever mounted to the first end portion of the link and rotatable between a blocked position and an unblocked position, the trigger lever having a first end portion and a second end portion; wherein the trigger lever is biased toward the blocked position and in the blocked position, the second end portion of the trigger lever contacts a first protrusion on the link and wherein in the unblocked position, the second end portion of the trigger lever abuts a second protrusion on the link. a link rotatable about an axis of rotation between a first position and a second position, the link having a first leg extending from the axis of rotation to a first end portion and a second leg extending from the axis of rotation to a second end portion; and a trigger lever mounted to the first end portion of the link and rotatable between a blocked position and an unblocked position, the trigger lever having a first end portion and a second end portion; wherein the trigger lever is biased toward the blocked position and in the blocked position, the second end portion of the trigger lever contacts a first protrusion on the link and wherein in the unblocked position, the second end portion of the trigger lever abuts a second protrusion on the link.
