2. Description of the Related Art Juggling refers to a technique of manipulating a plurality of objects in some way by throwing them into the air or dropping them on the ground to bounce them. Previously patented tools used for juggling,
There are many overseas, for example, US Pat. 4
696468 and NO. No. 4,279,416 is a patent for a juggling tool, similar to a boring pin, both called juggling clubs. Also, a patent for a juggling tool called a juggling stick (US Pat. No. 4,895,377) and a patent for an accessory attached to a tool called a diabolo (US Pat. No. 616)
2110). Greg Kennedy of the United States also devised a device in which a transparent hemispherical container was fixed with several columns and a method of manipulating a plurality (1 to 8) of balls in the hemispherical container. Juggling Association (Inte
national Jugglers' Assoc
iation (abbreviation IJA) in the championship (1996 IJA Championship Video).

[0003]

Among the juggling tools described in the related art above, in a juggling tool using a hemispherical container of Greg Kennedy, when the ball is rolled in the hemispherical container, the ball is placed in the container. It gradually attenuates while shaking inside, but it has the following two problems. The first point is that the hemispherical container is oriented so that the inside of the container faces upward.
When fixed to a height of about m, when viewed from the front or side,
Because only a semicircular portion is visible, it is difficult to directly determine how the balls are moving when rolling a plurality of balls in the container. Greg Kennedy himself placed a large mirror above the hemispherical container to overcome that challenge,
Through the mirror, the movement of the ball in the hemisphere container is indirectly seen from the front, albeit indirectly. The second point is
If you apply too much force on the ball, the ball will fly out of the hemisphere with too much momentum, so the force applied to the ball must be reduced. Therefore, games and stage performances using hemispherical containers lack dynamics.

The present invention has been made to solve the above two problems.
By using a spherical container as part of the juggling equipment, visibility from the front and side is improved, and even if any force is applied to the ball, the ball can stay in the spherical container and move dynamically The purpose of the present invention is to provide a new juggling tool that is interesting and has an impact on both a player and a viewer.

[Means for Solving the Problems]

Therefore, a juggling tool according to the first aspect of the present invention comprises a tool body composed of a hollow transparent or translucent spherical container having an opening on its surface, a base for supporting the spherical container, and a spherical body. It is a juggling tool comprising a plurality of balls inserted from the outside into the container.

BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be described with reference to the drawings based on an embodiment. Hereinafter, the portion of the juggling tool of the present invention except for the ball is referred to as a tool main body. FIG. 1 shows a front view of a tool body 1 of the present invention.
The tool body 1 includes a hollow spherical container 2 having a hollow inside, and a pedestal 3 for supporting and fixing the spherical container 2.

The pedestal 3 for fixing the spherical container 2 has a leg 1
1, an upper frame section 12, an intermediate frame section 13, and a lower frame section 14. Upper frame part 1
2. The intermediate frame portion 13 and the lower frame portion 14 are circular in the embodiment shown in FIG. 1, but may be replaced by polygons. The intermediate frame 13 and the lower frame 14
Any of the above can be excluded when the pedestal 3 and the spherical container 2 placed thereon are stable without it.
The material of the pedestal 3 is wood, a metal such as iron or copper, an acrylic resin, a vinyl chloride resin, or the like, and has such a rigidity that it cannot be bent by human power. Although the number of the legs 11 is four in the embodiment shown in FIG. 1, three legs may be used because the stability is good. In addition, if the legs can be firmly fixed at the ground, only one leg is possible at the center.

The spherical container 2 has a circular opening 4 in a direction perpendicular to the ground. The spherical container 2 is formed of a synthetic resin such as an acrylic resin or a vinyl chloride resin having a degree of transparency such that the inside can be visually recognized, or glass. The opening 4 is used for inserting a ball and a hand into the spherical container 2 when the juggling tool of the present invention is used. A shape other than a circle, such as a square shape or other irregular shapes, may be used. Spherical container 2
Has a diameter of 50 cm or more and 2 m or less, and the diameter of the opening 4 is 20
cm or more and within 1 m.

The legs 11 and the upper frame 1 of the pedestal
2. The intermediate frame portion 13 and the lower frame portion 14 are welded at portions where they are in contact with each other. However, it is also possible to bond instead of welding, or to assemble using a joint or the like in consideration of carrying. The manner of fixing the upper frame portion 12 and the spherical container 2 is by adhesion in the embodiment of FIG. Again, in consideration of carrying, the spherical container 2 is fastened and fixed at several places with the metal fittings attached to the upper frame portion 12, or a string or a wire tied to the upper frame portion 12 is turned over the sphere to re-start the upper frame portion again. It is also possible to stretch back and fix it.

The ball 5 used in the juggling device of the present invention has a weight of 50 g or more and 500 g or less, and a diameter of 5 cm or more and 15 cm or less, from the viewpoint that a person can easily insert his or her hand into the spherical container 2 and handle it. It is. A ball having a low coefficient of friction is preferable so as to easily rotate inside the spherical container 2, and particularly suitable balls are silicon balls, rubber balls, super balls, acrylic balls, and the like. For example, a silicon ball manufactured by Brian Debe of the United States (product numbers # 0430- # 0432)
Is very suitable. Also, for use in the dark,
A luminescent ball can also be used.

The above is the description of the juggling implement of the present invention. Hereinafter, a method of using the juggling implement of the present invention will be described based on embodiments.

First, two trajectories and two points on the inner wall of the spherical container 2 are prepared to facilitate the description of the method of use. FIG. 3 is a front view and a plan view of the spherical container 2.
A locus consisting of a great circle (circle having a diameter equal to that of the spherical container 2) that is “substantially parallel” to the opening 4 of the spherical container 2 is denoted by 21.
Here, instead of considering the great circle that is “parallel” to the opening 4, the reason why the great circle that is “substantially parallel” is used is that the great circle that is parallel to the opening 4 This is because it matches the outermost circle, making it difficult to understand the illustration. Let another trajectory be 22. Locus 21
There is a point 23 on the top and a point 24 on the trajectory 22. The points 23 and 24 represent points where the ball is pressed against the inner wall of the spherical container 2 by hand. Also in the plan view of FIG.
Trajectories and points corresponding to the two trajectories and points in the front view are shown.

In FIG. 3, one ball 25 is moved to point 2
When pressed against 3 along the trajectory 21 in a counterclockwise direction,
The ball rotates inside the spherical container along the trajectory 21 and returns to the original point 23. Grab it with your right hand near point 23. The method of rotating the ball as described above is based on the trajectory 2
It is also possible to use the trajectory 22 and the point 24 instead of the 1 and the point 23, and of course, it is also possible to use another trajectory.

An embodiment in which two balls are used will be described with reference to FIG. As in the case of one ball, the right hand holding the two balls 31 and 32 is put into the spherical container 2. First, the ball 31 is pressed at the point 23 along the trajectory 21 in the counterclockwise direction, as in the case of the single ball embodiment. The ball 31 goes around the trajectory 21 and the point 2
Immediately before returning to 3, another ball 32 was moved to point 2
3 along the locus 21 and rotate. The positions of the ball 31 and the ball 32 in FIG. 4 represent the position immediately after the ball 32 is pressed. After the ball 32 is pressed against the point 23, there is nothing in the right hand, so that the ball 31 returning to the point 23 can be caught. Next, before the ball 32 returns, the ball 31 is again pressed against the point 23 and rotated. Less than,
By repeating this operation, the two balls can be kept rotating in the spherical container.

The embodiment in which one or two balls are rotated in the spherical container 2 has been described above. However, if three or more balls are used, the trajectory of the ball, the point at which the ball is pressed, the timing at which the ball is pressed, and the like are possible. Because of the increased number of combinations, more diverse ball movements are possible, which allows for advanced use of the juggling implement of the present invention.

【The invention's effect】

Since the present invention is configured as described above, it has the following effects.

The juggling implement of the present invention allows for a fun game of rotating a plurality of balls in a transparent or translucent spherical container.

Furthermore, in the device of the present invention, the appearance of the ball rotating many times in the spherical container or the simultaneous rotation of a plurality of balls is very interesting to the viewer and has a strong impact, so that the stage or show Has the effect of enabling a performance that the audience can enjoy.
