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.
Claims4
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.
