Abstract
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.
Claims20
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 spade grip assembly for a machine gun, the assembly comprising:
- a housing;
- a first link mounted to the housing and rotatable about an axis of rotation between a first position and a second position, the first 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;
- a trigger lever mounted to the first end portion of the first 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;
- a second link rotatably mounted to the housing and having a first end coupled to the second end of the first link, the second link rotatable between a resting position and a fire position, wherein the second link is biased toward the resting position;
- a third link movably retained in the housing, the third link having a first end coupled to the second end of the second link and having a distal end portion extending longitudinally, the distal end portion having a catch surface configured to engage a trigger;
- and
- a stop surface on the housing, the stop surface positioned to contact the distal end portion of the trigger lever to prevent rotation of the link out of the first position when the trigger lever is in the blocked position;
- wherein 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.
