Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention mainly relates to a fireworks stand used for launching and firing toy fireworks.

(Prior art) There is a type of this type as shown in Utility Model Publication No. 57-47600, and there are also paperboard types that are attached to firework sets or sold separately.
The latter type has a folded structure in which two or more die-cut paperboards are pasted together. Therefore, bonding work is required at the manufacturing stage, and it is also necessary to use a member to correct the folded state or to stabilize the folded state using weights.

(Technical issues) The purpose of the present invention is to eliminate the need for pasting work and to be able to manufacture it using simple means such as die cutting, and to simply assemble it during use without requiring any weights or the like. The purpose is to provide fireworks stands.

The present invention achieves the above purpose by inserting fireworks 1
Alternatively, a flat plate-like upper base 5 having a pair of supporting pieces 3, 4 formed via folded lines on the periphery of a face plate 2 having two or more insertion holes 1 formed in the plate surface, and the insertion holes 1...
It consists of a flat lower base 10 with leg plates 8 and 9 formed via folding lines on both sides of a support plate 7 with corresponding pilot holes 6 formed therein. Support plate 7 and leg plates 8, 9 sandwiching the folding line
This is a fireworks stand in which slits 11 and 12 are formed in the extending portions, respectively.

(Function of the invention) The fireworks stand of the invention consists of an upper stand 5 having parts that become supporting pieces 3 and 4 by bending, and a lower stand 10 having similar leg plates 8 and 9. , along with the insertion holes 1, pilot holes 6, and necessary slits 11, 12, are formed by punching from an original plate with a mold or by only resin molding. Both members are assembled by fitting each other into the slits 11 and 12, and the slit 12 on the lower stand 10 side extends beyond the folding line to the support plate 7 and the leg plates 8 and 9.
Since it depends on the combination, it becomes a three-dimensional state and does not deform, so no other members are required.

(Example) To explain with the illustrated example, a face plate 2 in which many large and small insertion holes 1a, 1b, 1d and 1e are formed.
has a rectangular shape, with large trapezoidal support pieces 3 and 4 provided on two opposing sides of the four sides, and small trapezoidal sub-pieces 13 and 14 provided on the other two sides, both of which have folded edges. It can be bent at f to form a three-dimensional truncated pyramid shape. The supporting pieces 3 and 4 have notches 15 and 16, and the length from the upper sides 15a and 16a to the folding line f determines the height of the upper stand 5 assembled on the lower stand 10.

The lower base 10 has a support plate 7 having approximately the same width as the upper base plate 2, and the insertion holes 1a to 1e are formed in the center of the support plate 7.
Preparatory holes 6a to 6e are provided in the same arrangement, size, and shape, and leg plates 8 and 9 are provided on both sides along the long side.
is formed through a folding line f, and the line f has sub-piece locking protrusions 17 and 18 that protrude from the support plate surface.

The slits of the upper stand 5 are provided in four places on the left and right extension of the vertical folding curve f, and the slits 12 of the lower stand 10 are provided in four places in the support piece 7 at intervals of the width of the lower side of the sub piece, and are further inclined outward. It rests on leg plates 8 and 9. The upper stand 5 and the lower stand 10 are manufactured by punching or molding cardboard or synthetic resin plates, and when assembled, the support pieces 3 and 4 become the same as the lower sides of the lower stand leg plates 8 and 9, and the notches 15 and 16 serve as support pieces. In contact with plate 7, sub-piece 1
3 and 14 can be locked inside the protrusions 17 and 18 and can also contact the support plate 7. Therefore, each large and small insertion hole 1a~
Even if the toy firework H is inserted into 1e, it remains stable and the firework H is correctly held in a predetermined direction.

(Effects of the invention) Since the present invention is constructed and operates as described above, it is very easy to manufacture and can reduce labor and cost. Since it is only necessary to fit each other together, the structure is easy to assemble and has a strong and stable structure, and the effect of launching and discharging fireworks is easy and safe.
