Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a ball clacker that produces sound without using explosive gunpowder.

[Conventional technology]

The above-mentioned ball cracker is made of synthetic resin and consists of a pair of left and right half-sphere bodies with a string attachment hole in the center of the spherical surface and female and male fitting parts that can be removably tightly fitted to the open end. A bowl-shaped body, a loop-shaped tension string inserted through the string attachment holes of both of the bowl-shaped bodies, and a long piece of tape, folded bunting, etc. stored in the joint hollow body of the bowl-shaped body. There is an earlier device in U.S. Pat. No. 61-143122 filed by the present applicant, which has an extensible band-shaped ejecta.

[Problem that the invention attempts to solve]

In the ball cracker invented in the earlier application, when setting and storing a belt-shaped ejected material such as a rolled tape, one end of the ejected material is adhesively fixed in the bowl-shaped body, so it takes a lot of work to set and fix the ejected material. This has the disadvantage that it is inconvenient for the user to reset the attached band-shaped ejecta before use, and if the adhesive strength is weak, there is also the problem that the ejecta may fly out without opening when using the cracker. Occur.

[Means for solving problems]

In order to solve the problems of the previous invention, this invention was created by molding a synthetic resin in which a string attachment hole was provided in the center of the spherical surface with female and male fitting parts that could be removably tightly fitted into the open end. a pair of left and right bowl-shaped bodies, a loop-shaped tension cord that is inserted into the string attachment holes of both bowl-shaped bodies and attached thereto, and has a knob at its inner end to prevent the bowl-shaped bodies from slipping out; The bowl-shaped body is equipped with a rolled tape that is housed and set in the bowl-shaped body joining hollow body when they are combined to form a ball cracker, and a belt-like ejecta that can be extended into a long length such as a folded bunting flag, and the bowl-shaped bodies are separated. Then, pull one of the bowl-shaped body tension strings inward, insert the fastening part on one end of the band-shaped ejecta into the ring of the inner loop part of this tension string, and pull the tension string outward again. Accordingly, the ejected material is set and fixed.

[Effect]

By adopting the above-mentioned setting and fixing structure, the belt-shaped ejecta can be easily and reliably set and fixed to the bowl-shaped body, and it is convenient for the user to set and use the attached belt-shaped ejecta. Moreover, the problem of the ejected material flying out without opening when using the cracker can also be solved.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings. In the drawing, 1 and 2 are a pair of left and right bowl-shaped bodies molded from synthetic resin. One of the bowl-shaped bodies 1 has a string attachment hole 1a in the center of its spherical surface. It is formed of a half-sphere with a diameter of about 3 to 6 cm with a female fitting part 1b at the open end, and the other bowl-shaped body 2 has a string attachment hole 2a in the center of the sphere and has the female fitting part 1b at the open end. It is formed of a half-sphere having a diameter of about 3 to 6 cm and has a male fitting part 2b that can be removably and tightly fitted to the fitting part 1b.

5 and 6 are string attachment holes 1a and 2 of the bowl-shaped bodies 1 and 2.
A loop-shaped tension string with an appropriate tension length is inserted through and attached to a, and the tension strings 5 and 6 are formed of strong thick thread with a loop length of about 20 cm, for example.
At the inner ends thereof, there are provided knobs 5a, 6a for preventing slippage, which are formed by knots at both ends of the thick threads and can be locked onto the inner surfaces of the bowl-shaped bodies 1, 2. Reference numeral 7 denotes a long length of tape, folded flag, etc., which is stored and set in the bowl-shaped body joining hollow body 4 as shown in FIG. 2 when the bowl-shaped bodies 1 and 2 are combined to form a ball cracker. An extensible band-shaped ejecta, in the case of this embodiment, a plurality of small tapes 7a to 7e of different colors are bound by an outer ring 7f, and each small tape end is connected to the outer ring 7f. Tape is used.

The belt-shaped ejecta 7 made of this wound tape uses the outer ring 7f, which is removed from the small-wrap tapes 7a to 7e, as a fastening part on one end side of the belt-like ejecta 7, and this fastening part is attached to one of the bowls. It is set and fixed to a shaped body (for example, the right bowl-shaped body 2) as follows. That is, when the bowl-shaped bodies 1 and 2 are separated, one of the bowl-shaped bodies tension string 6
Pull it inward as shown in Figure 1, and then pull the pull cord 6
One end of the belt-shaped ejecta 7 (the outer ring 7f removed from the small tapes 7a to 7e) is inserted into the ring of the inner loop 6b as shown by the imaginary line in FIG. By pulling the tension string 6 outward again, the ejected material 7 is set and fixed. Once set and fixed in this way, the plurality of small tapes 7a to 7e that have been removed from the ring are stuffed into the bowl-shaped body 2, and the left and right bowl-shaped bodies 1 and 2 are joined as shown in FIG. to form a ball cracker.

This Ball Kratsker has left and right pull strings 5 and 6.
When you hold the hollow body 4 with both hands and pull it strongly so as to swing it forward, the hollow body 2 splits into two, making a loud "pop" sound, and along with this sound phenomenon, the band-shaped ejecta 7 inside. The liquid will open cleanly and be released.

[Effect of idea]

Since the ball cracker of this invention adopts the above-mentioned structure for setting and fixing the belt-shaped ejecta using the loop-shaped tension string, it can easily and reliably set and fix the belt-shaped ejecta to the bowl-shaped body. This is convenient when the user sets and uses the attached band-shaped ejecta, and also solves the problem of the earlier device in which the ejecta flies out without being opened when using the cracker.
