SOLUTION: In this eccentric ball for game in the form of cutting the solid sphere with one or two planes, various kinds of rolling are presented before stop because of a fine difference in the position of the center of gravity, a perspective is taken from both sight and touch by touching the difference of the form with hands and the rolling position of the ball can be surely grasped from the sight and the sense of hearing based on the sounds of a ringing bell by opening a through hole on this eccentric ball for game, incorporating the bell and plugging that hole.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION [0001] The present invention relates to an eccentric ball for a game that irregularly rolls and slides, so that infants, the elderly, disabled persons, and healthy persons can participate in games happily regardless of differences in skills and physical strength. The present invention relates to a game eccentric ball that can be used.

2. Description of the Related Art A conventional eccentric ball for a game is a ball toy for pets (actual opening 62-125553) in which weight iron or lead is buried at an eccentric position inside a solid styrofoam spherical body and eccentric. In addition, a hard rubber with a high specific gravity is provided to eccentrically shift the center of gravity of the solid ball, and the center of gravity is set at the eccentric position moderately. A golf ball having an irregular shape and irregularly flying and rolling (Japanese Patent Application Laid-Open No. 9-215776). As can be seen, eccentric balls incorporating weights having different specific gravities were formed to move the position of the center of gravity of the solid ball, thereby forming golf balls and pet toys. There is also a golf ball that has an elliptical shape or a dice shape and irregularly rolls. In addition, a new bowling game using unexpectedly rolling balls. There is a tool for promoting exercise of domestically raised animals.

[Problems to be Solved by the Invention] Conventional eccentric balls for games and toys for domestic animals have a solid sphere with a weight buried inside and a spherical, elliptical or dice-shaped body. Although the ball moves irregularly, the change in ball rolling is poorly diverse and the roll is biased to visual confirmation, and infants, children, the elderly, disabled people, and healthy people can To participate in the game happily beyond the difference in physical strength, it is difficult to attract and it is easy to be abandoned.
The first object of the present invention is to solve the conventional problems by changing the shape of the eccentric ball for games to diversify the rolling and to draw interest from the visual and tactile aspects. A second object is to make it possible to grasp from a visual and auditory aspect by emitting a sound when rolling.

[MEANS FOR SOLVING THE PROBLEMS] In order to achieve the first object, the present invention provides an eccentric ball for a game having a shape obtained by cutting a solid spherical body in one plane or two planes. It is divided into nine groups as shown in Table 1. The shape that is cut in one plane is three groups of ai u. The shape formed by cutting two planes is the three groups of Oka that are cut by two parallel surfaces, and the shape formed by cutting two surfaces that are not parallel is Kikuke 3 group. Of these, only one can be decided on one, but the other eight groups can change shape. The position of the center of gravity is the center of gravity G 'of the eccentric balls for game in nine groups with respect to the center of gravity G of the solid spherical body.
Is located on the opposite side of the cut plane A, and below in the case of two cut planes A and C. Although the difference in the position of the center of gravity of these nine groups is subtle, when the cut surface of the eccentric ball for games starts to tilt before stopping, the eccentric ball for games that rolls with a variety of rolls with a reduced inner diameter of the rolls is used. Can be provided. The diversification of the rolling of the eccentric ball for games due to the shape change can be grasped more surely by both visual and hand feeling. In playing this game, some of the nine groups shown in Table 1 are selected to provide a number of eccentric balls for games. In order to achieve the second object, an eccentric ball for game 1 having a shape obtained by cutting a solid spherical body in one plane or two planes is shown in FIG.
As shown in FIG. 2, the game eccentric ball which has a through hole 4 and a built-in bell 6 and plugs 5 on both sides of the hole as shown in FIG. The sound of the bell sounds from a stopper with a hole smaller than the bell, and the position of the eccentric ball for the game can be grasped from both the visual and the auditory senses.

The position of the center of gravity G 'is on the left side of G, and at the start of rolling, the radius of the roll is larger than that of A and the cut surface A faces upward earlier. Partly stop at "".

In the mosquito of FIG. 6, a through hole is formed in a game eccentric ball having a shape formed by cutting two planes A and B parallel to each other, a bell is built in, and a plug is inserted from both sides. The position of the center of gravity G 'is at the same position as G, and at the beginning of rolling, it goes straight with the same directionality as the spherical body, and stops quietly before stopping or stops below the cut surface A or B. .

The portion of the eccentric ball for game which is in contact with the spherical surface is flattened to make it feel better and to be injured even if it hits the body.

The material of the eccentric ball for the game is preferably plastic or wood, but may be waste plastic, thinned wood, driftwood, or fallen wood.

When a game is played, a number of eccentric balls for games having different shapes are prepared. For example, by combining the five types of KE, WE, and KA shown in Table 1, the way of rolling and sliding can be visually recognized. You can make predictions from both sides of the palm feel and grasp the position visually and audibly while listening to the sound of the bell.

A game using an eccentric ball for games may be used in a small space inside or outside the room, used for a short time regardless of individuals or groups gathered in advance of a row, and throws in one hand, two hands or standing.・ Since it can be used in any sitting position, it can be used as a toy for infants as well as functional training for the elderly and disabled.

The game eccentric ball rolls and rolls, and the bell rings and the game is hereinafter referred to as a corotin game. Corotinball competes for scores on parks and open spaces, on gravel-paved parking lots and sandy beaches, on the lawns of multipurpose plazas, on carpets indoors and on the roof, roll several types of eccentric balls for games and put them on the scoreboard. . During the competition, even people who meet for the first time have the opportunity to praise unintentionally, giving each other a sense of liberation and friendship.
