연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

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...

1. 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; anda 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. 2. The fireworks launcher of claim 1, wherein said reinforcing section is integrally molded with the launch tube. 3. The fireworks launcher of claim 1, an inner surface of said reinforcing section being adhesively connected with said tubular wall outer surface. 4. The fireworks launcher of claim 1, wherein said tubular wall and said reinforcing section are formed of high density polyethylene. 5. The fireworks launcher of claim 1, wherein said reinforcing section abuts said base. 6. The fireworks launcher of claim 1, wherein said reinforcing section has a height which is at least about 20% of the total height of said tubular wall. 7. The fireworks launcher of claim 1, wherein said combined thickness of said tubular wall and said reinforcing section is at least about 40% greater than said tubular wall thickness. 8. The fireworks launcher of claim 1, wherein the reinforcing section has a height which is from about 25% to 50% of the total height of said tubular wall. 9. The fireworks launcher of claim 1, wherein said combined thickness of said tubular wall and said reinforcing section is about 45% to 70% greater than said tubular wall thickness. 10. The fireworks launcher of claim 1, wherein the base includes a sidewall spaced from the launch tube and depending from the base wall to engage the ground. 11. 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; anda 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. 12. The fireworks launcher of claim 11, wherein said tubular wall and said reinforcing section are formed of high density polyethylene. 13. The fireworks launcher of claim 11, wherein said reinforcing section abuts said base. 14. The fireworks launcher of claim 11, wherein said reinforcing section has a height which is at least about 20% of the total height of said tubular wall. 15. The fireworks launcher of claim 11, wherein said combined thickness of said tubular wall and said reinforcing section is at least about 40% greater than said tubular wall thickness. 16. The fireworks launcher of claim 11, wherein the reinforcing section has a height which is from about 25% to 50% of the total height of said tubular wall. 17. The fireworks launcher of claim 11, wherein the base includes a sidewall spaced from the launch tube and depending from the base wall to engage the ground. 18. 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; anda 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. 19. The fireworks launcher of claim 18, wherein said tubular wall and said reinforcing section are formed of high density polyethylene. 20. The fireworks launcher of claim 19, wherein said reinforcing section abuts said base. 21. The fireworks launcher of claim 18, wherein said combined thickness of said tubular wall and said reinforcing section is at least about 40% greater than said tubular wall thickness. 22. The fireworks launcher of claim 21, wherein said combined thickness of said tubular wall and said reinforcing section is about 45% to 70% greater than said tubular wall thickness. 23. The fireworks launcher of claim 18, wherein the base includes a sidewall spaced from the launch tube and depending from the base wall to engage the ground.
