  • Patent number: 9097498
    Abstract: A weaponry target mechanism has a base having two pivot points, two support arms each pivotally connected to one of the pivot points, a third arm pivotally connected to the two support arms, and a platform pivotally connected to the third arm and pivotally connected by a fourth arm to one of the support arms. The base may have two additional pivot points. There may be two additional support arms each pivotally connected to one of the additional pivot points. There may be an additional third arm pivotally connected to the two additional support arms. The platform may also be pivotally connected to the additional third arm and pivotally connected by an additional fourth arm to one of the additional support arms. There may be a target attached to the platform. The target may assume an upright position and a dropped position.
