Description

[Detailed explanation of the invention] <Purpose of the invention><Industrialapplication> The present invention relates to toy fireworks, and is particularly concerned with toy fireworks that fly upwards while burning and emit a bursting sound when they almost reach their full height. It concerns the so-called whistle rocket fireworks that are emitted.

<Prior Art> Many attempts have been made to develop this type of whistle rocket fireworks in terms of safety, sound quality, and other aspects of entertainment. The present applicant has already proposed Utility Model Registration No. 1546899 (Utility Model No. 11040, ``Toy Fireworks'') and is in the process of obtaining the right. This device has a non-flammable partition between the gunpowder that makes a whistle-like sound as it rises, and the gunpowder that makes a bursting sound when it reaches its full height. This allows for sufficient flight distance and reliability. This is to obtain the generation of a plosive sound.

<Technical matters attempted to be developed> The present invention is a method of isolating the explosive between the part that produces a plosive sound and the part that produces a whistling sound, which is included in the applicant's prior art idea. The aim was to further improve on this and develop toy fireworks that could be used in a more diverse range of applications.

<<Structure of the invention>><Means for achieving the object> That is, the toy firework of the present invention has a non-flammable cylindrical case with one end closed, and the closed side thereof is filled with a pop explosive that emits a pop sound when burned, This is followed by a whistle-like gunpowder that produces a whistle-like sound when burned, in which a partition piece having a separately formed guide hole is provided between the pop-sound gunpowder and the whistle-like gunpowder. It is characterized by being partitioned, and is intended to achieve the above-mentioned purpose.

<Example> The present invention will be specifically described below based on the illustrated example. Reference numeral 1 refers to a toy firework according to the present invention, in which a non-flammable cylindrical case 2 made of, for example, plastic material contains a pop-sound gunpowder 3 that emits a popping sound when burned, and a whistle-like firework when burned. A whistle gunpowder 4 that produces a sound is filled, and a partition piece 5 is interposed between the pop gunpowder 3 and the whistle gunpowder 4 to separate them. Each of these parts will be explained in detail below.The cylindrical case 2 has a hollow and elongated shape, and in its completed state, for example, a support rod 7 may be fixed to the cylindrical case 2, as shown in FIG. 5a. An appropriate structure may be adopted, such as by providing wing pieces 8 on the opening side of the cylindrical case 2 to form a shape resembling a so-called rocket. Then, the explosive explosive 3 is filled into the closed side of the cylindrical case 2. Of course, in the specific manufacturing process, in most cases, the closed side of the cylindrical case 2 is directed downward, and the plosive explosive 3 is filled inside the cylindrical case 2. The bursting explosive 3 has a relatively coarse granular shape, and its composition is, for example, a mixture mainly consisting of sodium salicylate and potassium perchlorate. Of course, in addition to the above, it is of course possible to add a coloring agent or the like to make toy fireworks more interesting. A partition piece 5 is loaded next to such a pop-sound gunpowder 3, and this partition piece 5 is formed by separately molding, for example, a plastic material.
Although various shapes can be taken, at least the partition piece 5 is required to have a guide hole 6 that allows communication between the bursting explosive 3 side and the whistling explosive 4 side. The shape of this partition piece 5 can take various shapes as shown in FIG. 4 in addition to the shape shown in FIG. In other words, the overall shape is not only a simple flat plate (see figure a), but also
It can take the shape of a funnel (see b in the same figure), a cylinder (see c in the same figure), a stud-like shape (see d in the same figure), etc. Further, the guide holes 6 may have any suitable shape, such as forming not only one but a plurality of them (see e in the same figure). Such a partition piece 5 is filled with whistle gunpowder 4 at a constant pressure. Although this filling is performed under pressure,
Fill the same whistle gunpowder 4 in two stages to make it more suitable. Its composition is almost the same as that of Poppowder 3, which is a mixture mainly consisting of sodium salicylate and potassium perchlorate, but its properties are fine particles, almost powder-like. A fuse 9 is further provided to ignite the whistle gunpowder 4 inside the cylindrical case 2 filled in this way.

The present invention has the specific structure as described above, and operates as follows. First, in the case of a type that is equipped with a support rod 7, for example, it is inserted into a narrow-mouthed bottle and supported so as to stand almost vertically, and waits for preparation for ignition. On the other hand, if it is a so-called rocket type with wing pieces 8, it is made to stand vertically on a substantially flat surface, and then the fuse 9 is ignited. The ignited flame first moves from the fuse 9 to the whistle gunpowder 4, which starts combustion. At this time, the toy fireworks 1 fly upward due to the combustion energy, and at the same time vibrate the cylindrical case 2 and rise while emitting a flute-like sound. When the whistle gunpowder 4 is almost completely burnt out, the toy fireworks 1 stop rising, and the flame of the whistle gunpowder 4 passes through the guide hole 6 in the partition piece 5 and reaches the bursting gunpowder 3. It burns instantly and produces a popping sound. Of course, given that the whistling gunpowder 4 is a fine gunpowder, the guide holes 6 in the partition piece 5 may be kept in a hollow state when actually manufactured, but the whistling gunpowder 4 to be filled next However, in either case, the fire of the whistle gunpowder 4 will be transmitted to the burst gunpowder 3, so from the viewpoint of action, the whistle gunpowder 4 will be buried. Afterwards, a plosive sound occurs.

In addition, in the present invention, since the partition piece 5 is separately formed into a regular shape and loaded, the shape can be selected and determined in various ways, for example, leading to a plosive sound after a flute-like sound. Various settings such as the time lag and the size of the plosive sound can be made.

<<Effects of the invention>> As described above, in the present invention, the partition piece 5 is separately formed into a fixed shape, so that the bursting gunpowder 3 and the whistling gunpowder 4 are clearly separated, and the explosion in the bursting gunpowder is prevented. It can be manufactured without compromising the amount of air necessary to generate sound. Furthermore, by selecting and determining the appropriate shape of the partition pieces 5, it is possible to manufacture toy fireworks with various interests.
