Abstract

The present invention relates to an explosive filled with explosives and decorations such as ribbons and confetti, and firecrackers that eject the decorations by explosive explosions. The fixed ring is formed on the top of a spherical container formed by combining two hemispherical containers up and down. Formed and fixed to the ceiling or door frame, the inside of the container is provided with explosives and decorations, the upper and lower containers are separated by the pressure caused by the explosion of the explosives to be ejected by the explosive force and gravity, explosion The pressure of the gas caused by the explosion acts to separate the container by increasing the pressure inside the closed container, and the decoration is mainly ejected by gravity, so that a small amount of gunpowder is ejected. It is possible to eject a large amount of decorations, and in the direction of ejection of the decorations, High safety was secured by preventing the high-pressure gas from blowing off.

Description

Suspension Firecrackers {PENDANT TYPE FIRECRACKER}

The present invention relates to explosives filled with explosives and decorations such as ribbons and confetti, and firecrackers that eject explosives as explosives explode. A spherical shape in which two hemispherical containers are combined up and down to store explosives and decorations The container is formed, and a fixing ring is formed in the upper container so that it can be suspended from the ceiling, and the lower part exposes the string connected to the explosive, and when the string is pulled, the upper and lower containers are separated by the explosion of the explosive. It has a structure in which the inner decoration is ejected downward.

Firecrackers used for various events or toys have various detonation methods such as lighting a wick, pulling a string connected to gunpowder, or connecting a power supply to a primer through an electric wire. It has various forms such as flashes, fireworks, and spouts.

Firecrackers that explode by pulling strings and ejecting decorations, such as ribbons, are mainly used for celebration events. When you hold the conical or cylindrical body with your hands and pull the strings, the gunpowder explodes and explodes at the same time.

Such a conventional firecracker has a risk of a burn due to an explosion because the user must hold the main body by hand, and the risk of an accident due to the flame and the hot gas generated by the explosion is ejected in the same direction as the ejection direction of the decoration. This is not only very high, because the ejection of the decoration only by the pressure due to the explosion of the gunpowder had a very limited problem.

The present invention was devised in view of the above-mentioned problems, and formed a fixing ring on the top of a spherical container formed by combining two hemispherical containers up and down, and the inside of the container is decorated with an explosion such as an explosive body and a ribbon. When the detonation vessel is pulled exposed to the lower part, the explosives explode and the upper and lower containers are separated by the pressure, and decorations such as ribbons are ejected by the explosive force and gravity.

In particular, not only ejection of the decoration by the pressure of the gas generated in the explosion, the pressure of the gas due to the explosion serves to separate the container by increasing the pressure inside the closed container, and the decoration is mainly ejected by gravity, It is possible to eject a large amount of decorations even with a quantity of gunpowder, and a flameproof plate is installed between the explosive and the ornament to protect the ornament from the flames caused by the explosion.

13: stickers

14: fixed ring

21: ribbon

22: winding shaft

31: explosive

32: flameproof plate

33: reinforcement plate

The detailed configuration of the present invention will be described with reference to the accompanying drawings.

1 to 3, the hemispherical upper container 11 and the lower container 12 are combined to form a closed container, and a ribbon wound around the winding shaft 22 on the inner upper surface of the upper container 11. One end of the (21) is attached, the lower container 12 is embedded with an explosive body 31, the detonator connected to the explosive body 31 to be exposed to the outside through a hole formed in the lower container 12 do.

A flame retardant disk-shaped flame retardant plate 32 is placed on the upper part of the explosive 31, and an explosion line 34 can pass through the center between the explosive 31 and the lower container 12. There is a hole to be drilled, the reinforcing plate 33 formed in a spherical shape (ball surface) is installed so as to coincide with the inner surface of the lower container (12).

The flameproof plate 32 serves to protect the ribbon 21 from the flame generated when the explosive body 31 explodes, and the reinforcement plate 33 has a lower container by a force pulling the detonator 34 or a pressure at the time of explosion. (12) serves to prevent breakage.

When the explosive body 31 and the lower container 12 and the flameproof plate 32 are installed in close contact with these yarns without any empty space, the container itself explodes by acting as a primer, so as in FIG. 3. , Explosives (31) should be installed to maintain a proper distance from the lower container (12) and flameproof plate (32).

In storing the ribbon 21 in the upper container 11, one end of the ribbon 21 is fixed to the upper surface inside the upper container 11, as shown in Figs. 22), when the container is separated by the explosion, so that the ribbons 21 can be smoothly developed without tangling with each other, the process in which the ribbon 21 wound on the take-up shaft 22 is developed by gravity Depicted in FIG. 5.

Although a sticker 13 or the like is attached to the boundary between the combined upper container 11 and the lower container 12, the coupling means may be selected using various methods such as using an adhesive or elasticity of the container itself. It can be easily inferred by those skilled in the art to which the present invention belongs.

The present invention having such a structure is fixed to the ceiling or door frame, such as by using a fixing ring 14, the detonation line 34 is pulled out to explode, and when the explosion, the upper and lower containers are separated with explosions Figure 4 As in the built-in ribbon 21 is developed to create an entertaining atmosphere.

Confetti may be used instead of the ribbon 21 as an ornament ejected during the explosion, as shown in FIG. 6, and various different effects may be obtained by storing various ornaments in a container, such as dropping the ends of the ribbon 21.

After all, the technical idea of the present invention in the firecracker to eject the decoration using gunpowder, one end is attached to the inner surface of the upper container 11 in the hemispherical upper container 11 formed with the fixing ring 14 at the top. The ribbon 21 is wound around the winding shaft 22, and the hemispherical lower container 12 has an explosive body 31 to which the detonation line 34 is connected, and the lower vessel 12 has a detonation line 34 at the lower end thereof. ) Is formed through the hole through which the detonation line 34 is exposed to the outside, the flame-proof flame-retardant plate 32 of flame retardant material is provided on the explosive 31, the upper vessel 11 and the lower portion Suspended firecrackers characterized in that the container 12 is coupled up and down to form a sealed spherical container,

Suspended firecrackers, characterized in that between the explosive 31 and the lower container 12 is provided with a spherical disk-shaped reinforcement plate 33 formed with a hole through which the detonation line 34 can pass.

Suspended firecrackers characterized in that a plurality of colored papers are accommodated inside the upper container (11).

As described above, the present invention does not eject the decoration only by the pressure of the gas generated by the explosion, the pressure of the gas due to the explosion serves to separate the container by raising the pressure inside the closed container, the decoration is mainly gravity By ejecting by the, it is possible to eject a large amount of decorative objects with a small amount of powder, and the flame or high temperature, high-pressure gas is not ejected in the ejecting direction of the decoration can prevent fire and safety accidents.

In addition, by installing a flameproof plate between the explosive body and the decoration, to protect the decoration from the flames caused by the explosion, not only the aesthetic effect of maintaining the appearance of the decoration, but also prevents a fire that may be caused by a fire on the decoration. .
