  • Patent number: 5507496
    Abstract: A running target shooting range comprising an oscillating platform 21, wherein a marksman stands thereon so as to position himself or herself to fire bullets at a stationary target (not shown). The oscillating platform 21 is supported on and moves by rollers or wheels 31 which are positioned in a stationary base member 25 located below the surface of the oscillating platform 21. Pivot arm 32 engages both the stationary base member 25 and the oscillating platform 21 at a generally central location, wherein the platform is oscillatable about the pivot arm 32 when a drive mechanism, also housed in the stationary base member 25 is activated. The drive mechanism 80 comprises a gearmotor 81, which propels a rotary shaft 82 having one end engaging the motor and the other end including a small-toothed pinion wheel 84, and wherein the teeth on the pinion wheel 84 mate with matching teeth on the bottom side of a cam system when the shaft is rotated.
