[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a very entertaining game ball that draws a markedly changed track when a ball is thrown and causes a large irregular bounce when a ball is grounded.

[0002]

2. Description of the Related Art Conventionally, as game balls, there are rubber balls, baseball hard or soft balls, tennis hard or soft balls, and the like. Then, such a ball is usually set so that a track and a bounce having physical regularity are generated.

[0003]

The existing balls described above are suitable for use in games, but when used for games in parks, plazas, etc.,
It is limited to play such as mere catch ball.

The present invention seeks to provide a new ball which, when thrown, struck, and bounced, undergoes highly irregular changes that far exceed normal physical expectations. In this way, the ball play that is extremely entertaining is performed.

[0005]

[Means for Solving the Problems] The present invention has a form in which a required number of disk units 1a having a shape like a horizontally sliced spherical body is arranged at equal intervals and has elasticity. The present invention relates to a new game ball in which a disk-constituting disk group 1 made of a material is fixed in the center of each disk unit 1a at equal intervals.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 denotes a disk group for forming a ball, which has a form in which a required number of disk units 1a having the shape of a spherical body cut in a horizontal direction are arranged at equal intervals. It is a thing. A hole for penetrating the central shaft 2 described later is formed in the central portion of each disk unit 1a.

Incidentally, the overall size of the disk-constituting disk group 1 is usually about the size of a baseball, but it is of an appropriate size such as a volleyball size. Can be carried out.

Further, each disk unit 1a is made of a material having elasticity such as a soft synthetic resin material or a rubber material, and its peripheral edge is rounded to prevent danger. Configured.

Reference numeral 2 is a central axis, and 2a is a head body connected to the upper end of the central axis 2, the surface of which is a curved surface obtained by molding a spherical surface. In addition, a cylindrical screw portion for screwing a fixing screw 4 described later to the lower end of the central shaft.
2b is formed.

Reference numeral 3 is a ring-shaped spacer, and the above-mentioned ball-constituting disk group 1 is the ring-shaped spacer 3.
Are respectively interposed and penetrated through the central axis 2 at regular intervals.

Reference numeral 4 denotes a fixing screw body, which is fixed to each disk unit 1a by being screwed with the cylindrical screw portion 2b provided on the central shaft 2. Further, the surface of the head body 4a of the screw body 4 is configured to be a curved surface obtained by molding a spherical surface.

The present invention having the above-mentioned structure is used as a game ball involving movements such as throwing, hitting, rolling, etc. in the same manner as an ordinary ball.

Further, according to the present invention, since the whole disk group is formed by the ball-constituting disk group 1 arranged at equal intervals, and the disk group 1 is made of a material having elasticity, air resistance is improved. Even if you throw it based on, you will not go straight, and you will draw a track with unexpected and complicated changes based on the rotation of the ball and the wind pressure received.

Even when the ball bounces on the ground, the repulsive force acts irregularly on the basis of the ground contact point in the disk group 1 and its deformation, and the ball bounces laterally, for example. Will be rolled into.

[0015]

[Effects of the Invention] The present invention is made of a material having a shape in which a required number of disk units 1a having a shape like a horizontally sliced spherical body are arranged at equal intervals and having elasticity. Since the disk group 1 for ball construction is configured such that the individual disks 1a are fixed at equal intervals in the central portion thereof, it is possible to enjoy a very entertaining ball game. That is, according to the present invention, the ball makes an extremely complicated movement based on the elasticity of the disk-constituting disk group 1 itself, the air resistance against the elasticity, and the like. Therefore, unlike the conventional simple catch ball, it is possible to execute a new and interesting ball game which is remarkably surprising.
