ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is concerned with a skyrocket having multiple visual displays created by separate effects. More particularly, it is concerned with a skyrocket which provides a first visual display prior to launch generated by a first effect and which may continue after launching, and a second, separate visual effect which is displayed only after launching.
2. Description of the Prior Art
Skyrockets are ancient devices associated with celebrations, providing bright visual effects in the nighttime sky. Skyrockets as used herein are inexpensive fireworks, which typically include a guide stick, a fuse, with a rocket motor charge and an effect. Upon ignition of the motor, the skyrocket is propelled skywardly, with an internal timing fuse connecting the motor to the effect. When the effect ignites and explodes, flaming balls, commonly called “stars”, are distributed either randomly or in a desired pattern to provide a visual display.
However entertaining, such skyrockets are limited to the lifting process and explosion of the effect. There has thus developed a need for an improved skyrocket having greater capacity to entertain without a significant increase in expense to manufacture.
SUMMARY OF THE INVENTION
This need has largely been met by the skyrocket of the present invention. That is to say, the skyrocket hereof is capable of not only the customary display created by explosion of the effect once airborne, but also of providing uniquely entertaining displays prior to ignition of the lifting charge which may continue as the skyrocket moves upwardly in flight. The skyrocket uses a translucent or transparent nose cone which displays the visual effect, while maintaining the aerodynamic shape of the skyrocket during flight.
In greater detail, the skyrocket of the present invention includes a body to which a guide stick is attached, as is conventional. A transparent or translucent nose cone is placed on the body. First and second layered effects are carried by the body, and a propulsive or lifting charge is also connected to the body. An ignition fuse extends from the top of the nose cone, and a second fuse extends downwardly to the motor. A third fuse, which is a timing fuse, may be used to interconnect the motor with the second effect whereby a the effect ignites and explodes only after the rocket has reached the desired height after lift-off. The first effect is preferably a strobe-type effect which burns brightly in a pulsating or intermittent manner prior to lift-off providing a strobing light display, while the second effect explodes after the rocket has lifted into the air.
As a result, the rocket remains relatively simple and inexpensive, but provides added entertainment value because of the ignition of the initial effect displayed through or emanating from the transparent or translucent nose cone. The provision of a fuse extending upwardly from the first effect and remote from the motor enhances safety by limiting exposure of the user to the skyrocket's motor and bursting charge.
