Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
201 words
A target assembly comprising an impact receiver target and a corresponding target recorder, said impact receiver target comprising a circular central impact disc and a plurality of concentric conductive, impact rings adapted to be struck by a projectile; a backing plate; said impact rings being secured to said backing plate by annular, resilient, insulating members; said insulating members being nearly co-extensive with said impact rings; said insulating members having a first portion secured directly to the backing plate and impact ring and a second portion also secured to the backing plate but spaced from said impact ring; said second annular portion having an annular electrical contact strip imbedded therein which is connected to one of a first set of wires leading to the target recorder; the impact receiver target having a second set of wires leading to the target recorder which are connected to the impact rings; wherby when a projectile strikes the impact rings the annular, resilient, insulating members are compressed such that the annular contact strip contacts the impact ring thereby completing an electrical circuit to the target recorder and causing a digital indication to appear on the target recorder indicative of the particular impact ring which is struck.
