Aerial fireworks product having synthetic resinous stabilizing base

A self-propelled aerial pyrotechnic device comprising:

• a body at the upper end of the device including a collection of ignitable incendiary display materials and an engine containing a charge for propelling the device when the charge is ignited;
• and
• a base at the lower end of the device and secured to the body for stabilizing the device during flight,
• said device having a longitudinal axis of symmetry,
• said base comprising a framework including a plurality of longitudinally extending, laterally spaced, substantially similar legs disposed symmetrically about said axis of symmetry and strut structure interconnecting said legs and disposed symmetrically about said axis of symmetry,
• said legs cooperating to define therebetween a longitudinally extending receiving socket adjacent the upper end of the base,
• said engine of the device being received within said socket,
• said engine being bonded to the legs.

An aerial fireworks product comprising:

• a launcher including a tube and a base secured to said tube for supporting the tube in an upright condition on a supporting surface,
• said tube having upper and lower ends and a continuous, annular sidewall extending between said ends to define an elongated, internal launching chamber within the tube,
• said upper end of the tube being open;
• and
• a self-propelled aerial pyrotechnic device adapted for launching from said launcher, said device including,
• a body at an upper end of the device including ignitable incendiary display materials and an engine containing a charge for propelling the device when the charge is ignited,
• a base secured to the body and projecting therefrom at a lower end of the device for supporting the body above the lower end of the tube when the device is placed in the launch chamber with the upper end of the device up and the lower end of the device down, and for stabilizing the device during flight after launching from the tube,
• said base comprising a framework including a plurality of longitudinally extending, laterally spaced, substantially similar legs and strut structure interconnecting said legs, and
• a fuse secured to and leading from said engine,
• said tube having an internal diameter that exceeds the maximum transverse cross-sectional width of the device and a height that causes at least a portion of the body of the device to be surrounded by the wall of the tube when the device is contained within the launch chamber and to present a generally annular space between the body and the sidewall,
• said fuse having a length that exceeds the distance between its point of securement to the engine and the open upper end of the tube when the device is contained within the launch chamber whereby to cause the fuse to extend through said annular space and out the open upper end of the tube when the device is loaded into and contained within the tube in preparation for launching.
