发明名称 Catapult game
摘要 A game comprising (a) a missile in the shape of a spheroid having at least a portion of its surface defined by an outwardly presented face provided with a first type of contact engaging material; (b) a flexible resilient, self supporting sheeting material capable of manipulation with two hands, the shape of which is substantially biaxially symmetrical one axis of which is substantially greater than the other axis; (c) said flexible resilient, self supporting sheeting material having at least a portion of at least one of its surfaces covered with a second type of contact engaging material; (d) one of said contact engaging materials comprising a surface of textile material defined by a multitude of irregular filamentary formations and the other of said contact engaging materials comprising a covering being composed of upstanding hook-like filamentary formations adapted for removably retentive imbediment in said surface having irregular filamentary formations; (e) whereby when said missile is directed against the contact engaging material of said flexible resilient, self supporting sheeting material, said first and second types of contact engaging material engage with each other to removably retain said missile thereagainst in the area of impact; (f) said flexible resilient, self supporting sheeting material being further characterized by having an overall balance of general mechanical properties such that when said missile is engaged and interlocked to the contact engaging material of the flexible resilient sheeting material thereby being rendered removably retained, said flexible resilient sheeting material can be manually flexed by compressive force applied along the longitudinal axis from a resting planar configuration to a concave configuration such that the missile is removably retained in the concavity of the flexible resilient sheeting material, and said material can then be relaxed and then manually and forcibly snapped outwardly in a direction going from the concave configuration through the planar posture and into the convex configuration with sufficient force to thereby disengage the missile from the contact engaging material of the flexible resilient sheeting material and catapult said missile in the direction of convexity.
