Abstract
An improved, multiple-use fireworks launcher (10) is provided for the launching of fireworks such as an artillery shell (40) having a lower lift charge (42) and an upper effect charge (44). The launcher (10) includes a base (12), with an upstanding, open-top launch tube (14) operably coupled with the base (12). A reinforcing section (16) is positioned about the lower end of launch tube (14), and preferably comprises a tubular sleeve (36) tightly secured to the outer surface (32) of launch tube (14). The combined thickness of the tube (14) and section (16) are sufficient to prevent catastrophic failure of the launcher (10) in the event a shell (40) is improperly placed within the tube (14) in an inverted condition with the lift charge (42) thereof positioned over the effect charge (44).
Claims23
A fireworks launcher operable to launch a fireworks artillery shell having a lift charge and an effect charge, said launcher comprising:
- a base;
- an elongated, upright launch tube secured to said base and configured to receive said shell, said launch tube having a tubular wall presenting an uppermost open end remote from said base, an inner surface and an outer surface, and a tubular wall thickness between said inner and outer surfaces,
- said base including a base wall positioned outwardly from the launch tube to restrict the launch tube from tipping;
- and
- a reinforcing section from positioned above said base and in surrounding relationship to a portion of said outer surface of the tubular wall of the launch tube above said base,
- said launch tube being operable to permit ignition and launching of said shell when properly placed within said launch tube with said lift charge beneath said effect charge, the combined thickness of said tubular wall and said reinforcing section being sufficient to withstand potentially destructive forces generated within said launch tube in order to maintain the structural integrity of the launcher, in the event that said fireworks artillery shell is improperly placed within said launch tube and ignited in an inverted condition with said lift charge disposed above said effect charge.
A fireworks launcher operable to launch a fireworks artillery shell having a lift charge and an effect charge, said launcher comprising:
- a base;
- an elongated, upright launch tube located above said base and configured to receive said shell, said launch tube having a tubular wall presenting an uppermost open end remote from said base, an inner surface and an outer surface, and a tubular wall thickness between said inner and outer surfaces,
- said base including a base wall positioned outwardly from the launch tube to restrict the launch tube from tipping;
- and
- a reinforcing section integrally molded with said launch tube and positioned above said base in surrounding relationship with a portion of said tubular wall of said launch tube above said base,
- said launch tube being operable to permit ignition and launching of said shell when properly placed within said launch tube with said lift charge beneath said effect charge, the combined thickness of said tubular wall and said reinforcing section being sufficient to withstand potentially destructive forces generated within said launch tube in order to maintain the structural integrity of the launcher, in the event that said fireworks artillery shell is improperly placed within said launch tube and ignited in an inverted condition with said lift charge disposed above said effect charge.

- said base including a base wall positioned outwardly from the launch tube to restrict the launch tube from tipping;
- and
- a reinforcing section integrally molded with said launch tube and positioned above said base and in surrounding relationship with a portion of said outer surface of the tubular wall of said launch tube above said base, wherein said reinforcing section has a height which is at least about 20% of the total height of said tubular wall,
- said launch tube being operable to permit ignition and launching of said shell when properly placed within said launch tube with said lift charge beneath said effect charge, the combined thickness of said tubular wall and said reinforcing section being sufficient to withstand potentially destructive forces generated within said launch tube in order to maintain the structural integrity of the launcher, in the event that said fireworks artillery shell is improperly placed within said launch tube and ignited in an inverted condition with said lift charge disposed above said effect charge.
