Abstract

The present invention is a toy launcher system. A lightweight projectile has an exterior surface symmetrically disposed about an imaginary longitudinal axis and is generally spool-shaped. The launcher is composed of a shaft to which a flexible curled band is attached. The flexible curled band holds the projectile within its curvature. When the launcher is rotated by a user using a general throwing motion the band uncurls, thereby launching the projectile into flight.

Claims (10)

1. A toy launcher system, comprising:

a launcher;

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

a metal and/or plastic band having an end proximal to a user;

the metal and/or plastic band attached to said launcher at the end of said metal and/or plastic band proximal to a user, where the metal and/or plastic band holds said cylindrical projectile through circumferential application of a normal force and enables secure holding of said cylindrical projectile to said launcher;

launching said cylindrical projectile through application of a motive force, where said motive force acts upon said cylindrical projectile at a substantially right angle to said imaginary longitudinal axis;

said motive force and said normal force enabling lift in said cylindrical projectile in a direction perpendicular to said imaginary longitudinal axis.

2. The system according to claim 1 , where said motive force is provided by manual application.

3. The system of claim 2 , where said manual application includes a general throwing motion.

4. The system of claim 1 , where said cylindrical projectile is spool shaped.
