Abstract

A toy projectile and launcher system. The projectile is tubular in shape and lightweight. The projectile has an exterior surface that is symmetrically disposed about an imaginary longitudinal axis. The launcher has a holding trough that receives and holds the tubular projectile. Within the launcher is a spring loaded element. The spring loaded element selectively moves between a cocked position and a released position. The spring loaded element contacts the projectile in the holding trough as the spring loaded element moves from its cocked position to its released position. Contact with the spring loaded element causes the tubular projectile to launch into flight in a direction perpendicular to its longitudinal axis. Simultaneously, contact with the spring loaded element imparts a spinning rotation to the projectile, wherein the projectile spins about its longitudinal axis in flight. The spinning creates a Magnus effect on the projectile.

Claims

1. A toy projectile and launcher system, comprising:

a tubular projectile having an exterior surface that is symmetrically disposed about an imaginary longitudinal axis;

a launcher having a holding trough for receiving and holding said tubular projectile thereon;

a spring loaded element, supported by said launcher, that is selectively moved between a cocked position and a released position, wherein said spring loaded element contacts said tubular projectile in said holding trough as said spring loaded element moves from said cocked position to said released position, and wherein contact with said spring loaded element causes said tubular projectile to launch into flight in a direction perpendicular to said longitudinal axis while imparting a spinning rotation in said tubular projectile about said longitudinal axis that remains while in flight.

2. The system according to claim 1, wherein said spring loaded element includes a spring that stores spring energy when said spring loaded element is in said cocked position.

3. The system according to claim 2, further including a trigger mechanism for selectively retaining said spring loaded element in said cocked position and releasing said spring loaded element into said released position when said trigger mechanism is activated.

4. The system according to claim 1, wherein said tubular projectile is cylindrical in shape.

5. The system according to claim 4, wherein said spring loaded element includes a head that strikes said exterior surface of said tubular projectile at a tangent, therein imparting rotation to said tubular projectile.

6. The system according to claim 5, wherein said holding trough is supported on a base and said spring loaded element includes an arm that supports said head, wherein said at arm is coupled to said base at a pivot connection and wherein said arm pivots about said pivot connection when said spring biased element moves from said cocked position to said released position.

7. The system according to claim 1, wherein said spring loaded element contacts said exterior surface of said tubular projectile at a tangent, and wherein said spring loaded element moves linearly from said cocked position to said released position while contacting said tubular projectile, therein imparting rotation to said tubular projectile.

8. A toy projectile and launcher system, comprising:

a tubular projectile having an exterior surface that is symmetrically disposed about an imaginary longitudinal axis;

a launcher having a base, wherein said tubular projectile is selectively positionable on said base;

a hammer coupled to said base at a pivot connection, wherein said hammer can rotate between a cocked position and a released position about said pivot connection;

a spring for biasing said hammer in said released position;

a trigger catch for retaining said hammer in said cocked position when moved to said cocked position against said spring; and

a release for activating said trigger catch;

wherein said hammer strikes said exterior surface of said tubular projectile at a tangent when moving from said cocked position to said released position, therein launching said tubular projectile into flight in a direction perpendicular to said longitudinal axis and imparting a spinning rotation in said tubular projectile about said longitudinal axis.

9. The system according to claim 8, wherein said hammer includes at least one arm and a head that is moved by said arm, wherein said head strikes said cylindrical projectile when said hammer moves from said cocked position to said released position.

10. The system according to claim 9, wherein said head is fabricated from elastomeric material.

11. A toy projectile and launcher system, comprising:

a tubular projectile having an exterior surface that is symmetrically disposed about an imaginary longitudinal axis;

a launcher having a spring loaded head that moves from a cocked position to a released position, wherein said head contacts said cylindrical projectile at a tangent when moving between said cocked position and said released position and imparts both a forward velocity in a direction perpendicular to said longitudinal axis and a rotational velocity that rotates said cylindrical projectile about said longitudinal axis.

12. The system according to claim 11 further including a holding trough on said launcher for receiving and holding said tubular projectile thereon.

13. The system according to claim 11, wherein said spring loaded head includes a spring that stores spring energy when said spring loaded head is in said cocked position.

14. The system according to claim 11, further including a trigger mechanism for selectively retaining said spring loaded head in said cocked position and releasing said spring loaded head into said released position when said trigger mechanism is activated.

16. The system according to claim 11, further including a base and an arm coupled to said base at a pivot connection, wherein said arm pivots about said pivot connection when said spring biased head moves from said cocked position to said released position.

15. (canceled)
