Abstract
A multiple-use fireworks launching tube for the launching of consumer fireworks such as an aerial display shell having a lower lift charge and an upper effect charge. The launching tube includes a base and a one-piece, elongated tube extending from the base. The elongated tube has a tubular wall with a reinforcing lower section that includes a series of outwardly extending circumferential ribs that are spaced apart by recessed circumferential regions located between adjacent ones of the circumferential ribs. A tubular wall thickness of the circumferential ribs may be greater than a tubular wall thickness of an upper section of the tubular wall. Circumferentially spaced-apart ribs extend between the adjacent ones of the circumferential ribs.
Claims18
A launching tube for launching a consumer fireworks aerial display shell having a lift change and an effects charge, the launching tube comprising:
- a base;
- an elongated tube extending from the base and comprising a tubular wall having an outer surface and an inner surface that defines a cylindrical interior passage for receiving and guiding an aerial display shell during its launch, the interior passage extending in a direction toward the base from an open end that is remote from the base;
- the tubular wall having a reinforcing lower section that is located between the base and an upper section of the tubular wall;
- and
- the reinforcing lower section of the tubular wall comprising:
- a series of spaced-apart circumferential ribs that extend in a direction outwardly from the inner surface and have a tubular wall thickness that is greater than a tubular wall thickness formed by circumferential regions that are located between adjacent ones of the circumferential ribs,
- wherein the tubular wall thickness of the circumferential ribs is greater than a tubular wall thickness of the upper section of the tubular wall;
- and
- circumferentially spaced-apart connecting ribs extending between adjacent pairs of the circumferential ribs.
A launching tube for launching a consumer fireworks aerial display shell having a lift change and an effects charge, the launching tube comprising:
- a base;
- a one-piece elongated tube formed integrally with and extending from the base, the elongated tube comprising a tubular wall having an outer surface and an inner surface that defines a cylindrical interior passage for receiving and guiding an aerial display shell during its launch, the interior passage extending in a direction toward the base from an open end that is remote from the base;
- the tubular wall having a reinforcing lower section that is located between the base and an upper section of the tubular wall;
- and
- the reinforcing lower section of the tubular wall comprising:
- a series of spaced-apart circumferential ribs that extend in a direction outwardly from the inner surface and have a tubular wall thickness that is greater than a tubular wall thickness formed by circumferential regions that are located between adjacent ones of the circumferential ribs;
- and
- circumferentially spaced-apart connecting ribs extending between adjacent ones of the circumferential ribs.
A launching tube formed of high-density polyethylene for launching a consumer fireworks aerial display shell having a lift change and an effects charge, the launching tube comprising:
- a base;
- a one-piece elongated tube extending from the base, the elongated tube comprising a tubular wall having an outer surface and an inner surface that defines a cylindrical interior passage for receiving and guiding an aerial display shell during its launch, the interior passage extending in a direction toward the base from an open end that is remote from the base;
- the tubular wall having a reinforcing lower section that is located between the base and an upper section of the tubular wall;
- and
- the reinforcing lower section of the tubular wall comprising:
- a series of circumferential ribs that extend in a direction outwardly from the inner surface and are spaced apart by circumferent regions that are located between adjacent ones of the circumferential ribs, the circumferential ribs having a tubular wall thickness that is greater than a tubular wall thickness of the circumferential regions;
- and
- circumferentially spaced-apart connecting ribs extending between the adjacent ones of the circumferential ribs,
- wherein the tubular wall thickness of the circumferential ribs is greater than a tubular wall thickness of the upper section of the tubular wall,
- wherein the tubular wall thickness of the circumferential regions that are located between adjacent ones of the circumferential ribs is greater than the tubular wall thickness of the upper section of the tubular wall,
- wherein a longitudinal length of the upper section of the tubular wall is greater than a longitudinal length of the reinforcing lower section.
