Patent ID: 7380796

Claim:
A portable 3-D archery target for absorbing an impact from an arrow moving with at least 100 in-lbs of kinetic energy such that the impact provides an impact force of at least 20 pounds of force and the arrow penetrates the portable 3-D archery target, wherein the portable 3-D archery target can be freely set upon a target-supporting surface in an unanchored manner, the portable 3-D archery target comprising: a foam body having a weight, the foam body has a three-dimensional curved outer surface to provide at least some animal resemblance: the foam body includes a bottom surface that can be freely set upon the target-supporting surface, the foam body has a center of gravity at a height above the bottom surface, the bottom surface has a lower rear edge about which the foam body can pivot in reaction to being struck at the center of gravity by the arrow delivering the impact force of at least 20 pounds of force, the impact force times the height imparts a tipping rotational moment that urges the foam body to pivot about the rear edge, the weight of the foam body provides an anti-tipping rotational moment about the rear edge, wherein the anti-tipping rotational moment opposes the tipping rotational moment, the tipping rotational moment is greater than the anti-tipping moment, however, the foam body has a quality such that most of the 100 in-lbs of kinetic energy is absorbed within the foam body so that there is insufficient remaining kinetic energy left to completely tip over the foam body, and further wherein the foam body comprises an upper section and a lower section, the upper section has a maximum horizontal cross-sectional area, the lower section defines a horizontal base envelope that is smaller than the maximum horizontal cross-sectional area, an intermediate horizontal cross-sectional area is interposed between the upper section and the lower section, and the intermediate horizontal cross-sectional area is smaller than the maximum horizontal cross-sectional area and is smaller than the horizontal base envelope.
