Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to toy fireworks, and in particular, a plurality of sparklers pivoted to a support member slowly rotate from an upright position to a diagonally downward direction after ignition, and then stop, forming a pyramid-shaped firework. It is a thing that seems to be made.

Toy fireworks in which multiple sparklers open after ignition are devised by Utility Model Publication No. 42694/1973,
The invention of No. 2-104979 and the invention of Utility Model Application No. 55-074420 filed by the present applicant have been proposed.

These sparklers each have a plurality of sparklers each having an explosive part and an elastic shaft part, and the upper ends of each explosive part are brought into close contact with each other, and each shaft part is held in an inwardly curved state, and the latter sparkler is ignited. However, the angle at which each sparkler opens after ignition is small, less than a few tens of degrees, and each sparkler opens only by the elasticity of its shaft. However, the problem was that the sparklers opened almost instantaneously, making it uninteresting in that it was impossible to enjoy the process of each sparkler opening.

The present invention has been made to solve the above-mentioned problems, and the lower ends of the shafts of a plurality of sparklers are respectively pivotally connected to a support member and the gunpowder of each sparkler is connected to the supporting member. By bringing the upper ends of the parts into close contact with each other, the igniting sparkler slowly rotates to a predetermined diagonal downward direction due to the elasticity of the shaft part and its own weight, and then stops, forming a pyramidal shape.

The present invention will be specifically described below based on illustrated embodiments.

The reference numeral 1 in the figure is a sparkler, the reference numeral 2 is a support member, and the reference numeral 3 is a handle.

The sparkler 1 may be of any type as long as it has at least a gunpowder part 5 and an elastic shaft part 4, such as one in which the shaft part 4 is coated with gunpowder, or one in which a gunpowder cylinder is fixed to one end of the shaft part 4. However, although it does not matter whether the gunpowder cylinder is filled with gunpowder or the shape, structure, etc. of the gunpowder cylinder, it is preferable that each sparkler has a different bright color.

However, in the present invention, a plurality of (for example, 3 to 3)
The lower ends of the shafts 4 of the four (4) sparklers 1 are pivoted to the support member 2 at equal angular intervals and locked thereto, with the shafts 4 of each sparkler 1 slightly curved inward. This is to bring the upper ends of each explosive portion 5 into close contact with each other.

That is, as an example, a locking piece 8 having a projection 6 and a locking projection 7 is fixed to the lower end of the shaft portion 4 of each sparkler 1, and a hole corresponding to the projection 6 is formed in the support member 2. 9 and a locking portion 11 corresponding to the locking protrusion 7 are provided, and the protrusion 6 of each locking piece 8 is inserted into the hole 9 of each pivot portion 10 in the support member 2. The locking protrusion 7 of the locking piece 8 is brought into contact with each locking portion 11 of the support member 2.

Furthermore, while the shaft portion 4 of each sparkler 1 is slightly curved inward, the upper ends of each explosive portion 5 are tightly attached to each other using, for example, paint tape, medicine M12, or an igniter having adhesive properties. let

In any case, it is desirable to apply ignition powder to the contact area.

Note that the locking piece 8 does not necessarily need to be used, and instead of using this piece, the lower end of the shaft portion 4 of each sparkler 1 may be appropriately bent to attach each pivot portion 10 in the support member 2.
into the holes 9 of the support member 2, and insert the tips of the bent portions into the support member 2.
There is no problem even if it is brought into contact with each locking part 11 of.

Further, the ignition latter sparkler 1 rotates in a predetermined direction,
In order to stop the rotation at a predetermined downward inclination angle, a guide 13 is provided on the support member 2 to restrict the rotation direction and rotation angle of each sparkler 10. The piece 8 is provided at a position corresponding to the shaft portion 4.

As this guide 13, it is desirable to provide a notch in the base of the support member 2, as shown in the figure.

A handle 3 is fixed to the support member 2.

As an example, the handle portion 3 can be erected on the support member 2 through the center of the contact portion at the upper end of the sparkler/explosive portion 5 as shown in the drawing.

The toy fireworks according to the present invention constructed as described above can be used in the following manner.

That is, as shown in Figure 1, each sparkler 1 holds the handle 3 in a substantially upright state, and ignites the upper end of the sparkler powder part 5 in close contact with it as shown by the chain line in Figure 2.

Then, the tape, medicinal paper, ignition powder, etc. that had brought the upper ends of each explosive part 5 into close contact with each other are burned and the close contact is released.

In such a case, each sparkler 1 opens outward due to the elasticity of the core shaft portion 4 and continues to open since the lower end of the shaft portion 4 is locked to the support member 2 with the shaft portion 4 slightly curved inward. hand,
Due to its own weight, it slowly rotates in the direction shown by the arrow in FIG. 3 about the pivot point at the lower end of the shaft portion 4.

At this time, since the support member 2 is provided with a guide 13, the locking piece 8 or shaft portion 4 of each sparkler 1 is guided by the guide 13 and rotates in a predetermined direction, so that the sparkler 1 rotates at a predetermined downward inclination angle. When the locking piece 8 or the shaft portion 4 comes into contact with the edge of the guide 13, each sparkler 1 stops rotating (solid line in Fig. 2, chain line in Fig. 3), and from then on it remains in this state. It continues to burn.

As detailed above, in the toy fireworks according to the present invention, the lower ends of the shafts of the plurality of sparklers are pivotally connected to the support member, so that the latter sparklers can be rotated significantly from an almost upright position to diagonally downward. .

However, once each sparkler opens due to the elasticity of the shaft portion, it rotates downward due to its own weight, so it rotates slowly.

Furthermore, since a guide is provided on the support member, each sparkler
rotates in a predetermined direction to a predetermined downward inclination angle and stops, forming a pyramidal shape.

Therefore, the toy fireworks according to the present invention are much more interesting than conventional fireworks.
