Abstract: An inflatable barrier with an integral, triple chamber construction. An upper air chamber of relatively greater volume may be configured in any convenient shape such as pyramids, cylinders, cubes and barricades as suitable for use at combat sports venues. A centrally disposed, water-filled chamber provides sufficient weight to resist displacement of the barrier to normal impacts. A peripheral lower air chamber surrounds the water-filled chamber to stabilize lateral support and to maintain an upright orientation of the barrier.

Abstract: A yieldable sports pole supported entirely above ground in a vertical orientation by a flexible bladder filled with a weighting fluid. A central opening through the bladder receives the pole. Underlying the bladder and connected to the pole is a ground engaging disc fabricated of a semi-rigid, resiliently springy material. When the pole is tilted to one side, as when experiencing an impact, the disc member and flexible bladder act in combination to cause the pole to return to an upright orientation.

Abstract: A low pressure, low velocity projectile marker for youth shooting sports as an acceptable alternative to the traditional sport of paintball. The marker includes an onboard, hand activated pressure system to charge an air reservoir up to a maximum pressure of 150 psi (11 kg/cm2) as limited by a pressure relief valve. A removable barrel/magazine assembly stores and visibly displays a plurality of projectiles. The barrel/magazine assembly is inserted and sealably locked into a pressure deliver conduit of the marker. A trigger mechanism operates a fire control valve to precisely release a controlled, momentary pulse of compressed air in order to discharge a single projectile through the barrel of the marker.

Abstract: In summary, a lower impact, reusable marker projectile for youth shooting sports as an acceptable alternative to the traditional sport of paintball. The projectile is fabricated from durable polymer material to conform to the circular bore of a barrel for discharge under the influence of a pneumatic or mechanical force. The projectile incorporates a marking agent retainer to carry a sufficient quantity of liquid or powder marking agent to leave a visual indication of impact location on a target. The projectile may alternatively be formed in a general cone-shape or a sphere-shape. The cone-shaped projectiles are capable of being nested without distortion and without wedging for the purpose of condensed storage.
