Description

Technical Field

The present invention generally relates to a ball with an information display function. More particularly, the present invention relates to a ball with an information display function, which collects motion information according to a movement of the ball via a sensor installed inside the ball and which outputs the motion information via a display.

Background Art

Various sports are played using a ball, for example, soccer, basketball, volleyball, and the like. With industrialization, sports are enhanced in a scientific manner, and application of advanced technology to sports is increasing.
Particularly in sports using a ball, a flying direction and distance of the ball, the magnitude of impulse applied to the ball, or whether the ball curves due to spin placed on the ball are considered as the important factors of the sports.
Consequently, technology for collecting motion information of a ball has been developed, and Korean Patent Application Publication No. 2004-0007847 discloses technology for displaying movement speed of a ball on a display board using an external sensor when a soccer ball is kicked to hit a target.
However, application of the above-mentioned technology is excessively restrictive because information is collected in a restricted space in which a measurement device is equipped to measure motion information of a ball. Also, as the technology may detect an object besides a ball, it is difficult to obtain desired information without an error.

Referring to FIG. 7, the display unit 110 and the solar cell 1310 may be attached on the inner surface of the covering 15 of the ball 10.
In this case, the display unit 110 and the solar cell 1310 are covered with the covering 15 of the ball 10, but the parts of the covering 15 for covering the display unit 110 and the solar cell 1310 may be made of a transparent material.
In this case, the display unit 110 and the solar cell 1310 are connected with a central circuit unit 1000 through an electric wire 11 so as to give and receive a signal or power.
The central circuit unit 1000 including the communication unit 120, the power supply unit 130, and the sensor unit 140 is located at the center of the ball 10, and the central circuit unit 1000 may be fixed to the covering 15 of the ball by being connected to the wire support 12.
In this case, the wire support 12 may be made of materials such as elastic steel, rubber, or plastic.
On the other hand, it is possible to locate the center of gravity of the ball at the center of the ball by dispersively disposing the center-of-gravity control units 150 of which the weight corresponds to the weight of the display unit 110 and solar cell 1310, on the inner surface of the covering 15 of the ball 10.
In this case, the center-of-gravity control units 150 may be arranged both on the point opposite the display unit 110 and on the point opposite the solar cell 1310 so as to form a cross shape.
Also, assuming a virtual line perpendicular to the cross-form of a extension line, which is generated by arranging the center-of-gravity control units 150 respectively opposite the display unit 110 and opposite the solar cell 1310, it is desirable to additionally arrange the center-of-gravity control units 150 on the both points at which the virtual line meets the covering 15 of the ball 10.
In this case, it is desirable that the weight of the display unit 110 is the same as the weight of the solar cell 1310.
In this case, as shown in FIG. 8, depending on the locations of the display unit 110 and solar cell 1310, a plurality of center-of-gravity control units 150 of which the weight corresponds to the weight of the display unit 110 and solar cell 1310 may be dispersively disposed on the inner surface of the covering 15 of the ball 15.
In this case, the number of the center-of-gravity control units 150 is not necessarily four. Depending on whether the solar cell 1310 exists and depending on the dispositions of the display unit 110 and the solar cell 1310, both the number and the location of the center-of-gravity control units 150 may be changed.
Also, when each of the units included in the central circuit unit 1000 is dispersively disposed on the inner surface of the covering 15 of the ball 10 rather than disposed at the center of the ball 10, it is possible to dispersively dispose the center-of-gravity control units 150 at random locations on the inner surface of the covering 15 of the ball to adjust the center of gravity.
Also, removing the solar cell 1310, the center-of-gravity control unit 150 may be disposed at the location of the solar cell 1310 to substitute the solar cell 1310.
Also, when the lighting unit 160 is disposed on the inner surface of the covering 15 of the ball 10, the center-of-gravity control unit 150 of which the weight corresponds to the weight of the lighting unit 160 may be additionally disposed inside the ball.
