Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to rotating toy fireworks.

(b) Prior art and problems to be solved by the present invention Conventionally, as shown in Figure 1 of the drawings, a circular support plate 7 is filled with explosives 2 that generate sparks, smoke, etc. from flames. Attach the paper tubes 1 and 1 of the book symmetrically,
Both left and right ends of the paper tube 1 are sealed with plugs 3, 3, and
The ends of the fuse wires 6, 6' formed in a bifurcated shape are specially inserted into the injection hole 4 formed in one of the plugs 3, the ignition charge 5 is attached to the outer surface of the injection hole 4, and the upper surface of the paper tubes 1, 1 is There was a rotating toy firework in which a covering paper 8 was overlapped and the lower end of a hanging string 9 passing through the center of the covering paper 8 was attached to the center of the support plate 7.In this type of firework, the fuse 6 is ignited. Then the fire will be the fuse 6,
6' and reaches the ignition powder 5, which ignites the gunpowder 2 in the paper tubes 1 and 1 and sends flame, sparks, smoke, etc. to the injection hole 4.
It rotates around a hanging string 9 while spraying from the paper cylinder 1, but since it takes time and effort to fill the paper tube 1 with gunpowder 2 and seal both left and right ends with plugs 3, the manufacturing cost is high. There was a drawback.

There is also a rotating firework disclosed in Japanese Utility Model Publication No. 43-22320, but this firework, like the one described above, also uses a pair of gunpowder barrels, so it has the disadvantage that it is time-consuming to manufacture.

On the other hand, there are blow-out fireworks described in Publication of Utility Model Publication No. 17758/1975 that can solve the above-mentioned manufacturing problems. A flammable material is filled between the nozzle hole and the fuse inserted into the nozzle hole, which is inserted into the nozzle hole. As mentioned above, plaster and clay are usually used, which makes the product heavy, so if it is used for rotating fireworks, it will not be possible to obtain a sufficient rotation speed. Both the preparation work and the work of filling the nozzle with combustible material cannot be carried out easily, so this poses a serious problem in manufacturing.

(c) Means for solving the problems The present invention was devised to solve the conventional problems as described above.

That is, in the present invention, a large number of cylindrical solid gunpowder are put into a rotating drum and rolled around inside the drum, and wood powder is sprinkled little by little on the surface of the solid gunpowder by applying glue and sprinkling wood powder on the surface of the solid gunpowder. The shell is solidified into a spherical shape, a jet hole is drilled in the wood powder outer shell that reaches the inside of the solid gunpowder, and a fuse is inserted into the jet hole.
The injection holes are glued to the front and back sides of a support plate on which two right and left blow-out fireworks with igniters attached to the outer surface of the injection holes are hung by hanging strings, so that the injection holes face oppositely to each other. To provide a toy firework which can be easily mass-produced at low cost and can be rotated at high speed, by joining the ends of two fuses in each blow-out firework.

(d) Embodiment and operation An example of the implementation of the present invention is now shown in Figures 2 and 3 of the drawings.
The explanation with reference to the figures is as follows.

In the figure, A and A are mass-produced by using a press to put a large number of cylindrical solid gunpowder 1a into a rotating drum and rolling it around in the drum, and by sprinkling wood powder little by little while applying glue. The outer shell 2a made of wood powder 3a is hardened into a spherical shape on the surface of the solid gunpowder 1a,
A nozzle hole 4a that reaches the inside of the solid gunpowder 1a is drilled in the outer shell 2a, a fuse 5a is inserted into the nozzle hole 4a, and two left and right blow-out fireworks are made with ignition powder 6a attached to the outer surface of the nozzle hole 4a. Then, the injection holes 4a are bonded to both the front and back surfaces of the support plate 7a so that they are oriented in opposite directions in the front and rear directions, and the two fuse wires 5a, 5 are
The tip of a is joined. Reference numeral 8a is a hanging line fixed to the upper end of the support plate 7a.

Since the present invention is structured as described above, now,
If the fuse 5a is lit, the flame will spread between the fuses 5a, 5a
The solid gunpowder 1a is ignited and flame, sparks, smoke, etc. are ejected from the injection hole 4a while rotating around the hanging string 8a. However, the two blow-out fireworks A and A on the left and right are spherical and have low air resistance, and their outer shells are made of wood powder and are lightweight, so they rotate vigorously and at high speed, making them interesting to watch. .

(e) Effects of the invention As mentioned above, this invention uses spherical fireworks with low air resistance and light weight that are glued to both the front and back sides of the support plate, so they are more powerful and faster than conventional fireworks of this type. Since it rotates, it is interesting to watch.

Blow-off fireworks are made by putting a large number of cylindrical solid gunpowder into a rotating drum and rolling it around inside the drum, and by sprinkling wood powder little by little while applying glue, a wood powder shell is formed on the surface of the solid gunpowder. Since the shell is solidified into a spherical shape, it can be easily mass-produced without the hassle of shaping each individual piece into a spherical shape, as in the past, so it has great practical effects as a rotating toy firework. It is something to do.
