Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ball detection device for gateball, and is devised to automatically notify that the ball has played a gateball and that the ball has touched a goal post.

Gateball has recently become very popular, especially among the elderly, as an outdoor sport that can be easily enjoyed by everyone from children to the elderly.

Gateball, as is well known, is a game in which five players from each team hit the ball with sticks to pass through a gate, which is a predetermined barrier, and the winner is determined by the points scored when the ball hits the goal post. .

Gateball has recently become very popular, especially among the elderly, as an outdoor sport that can be easily enjoyed by everyone from children to the elderly. As shown in the figure, in this game of gateball, five players from each team hit the ball with their sticks, and the winner is determined by the score they get until they hit five goal bosses while hitting the gateball, which is a predetermined barrier.

In such gateball, the referee visually recognizes whether the ball passes through the gate or hits the goal post and makes a decision. Therefore, misjudgments by referees are unavoidable, and the game lacks entertainment.Therefore, there is a long-awaited development of gates and goal posts that can objectively notify the passage and contact of the ball and also make the game more interesting. There is.

In view of the above-mentioned needs, the present invention provides a ball detection device for gateball that can automatically detect that the ball has passed through a gate and that the ball has contacted a goal post, and can also increase the interest of the game. The purpose is to The present invention achieves this object by detecting the passing of a ball through a gate by blocking light, and detecting the contact of a ball with a goal post by detecting pressure based on the kinetic energy of the ball acting on the goal post. The feature of the structure is that the notification is made by means of notification means that detects the information and emits light and/or sound.O Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, both legs 1a and 1bK of a portal-shaped gate 1 for gateball have a light-emitting part 2a and a light-receiving part 2b of a cell 2 facing each other and fixed to each other. The light receiving section 2b receives the light emitted from the light receiving section 2b. This sensor 2 is not particularly limited, but may be composed of a light emitting diode and a phototransistor, for example. Said gate 1
A detector 3 and a notification means 4 are placed on the upper surface VC. Among these, the detector 3 is connected to the leg portion 1 a r of the gate 1.
The sensor 2 operates when the sensor 2 detects the passage of the ball 5 through the space 1b and the light is blocked. Further, the notification means 4 is the detector 3
When the ball 5 is driven by the gate 1 and passes through the gate 1, it emits sound and light, or either sound or light, to announce the passage. The sound at this time may be a normal buzzer sound, but a special fanfare or the like may be played to make the game more interesting.

That is, there are no special limitations. The same holds true for light, and a special light-emitting state can be created arbitrarily.

FIG. 2 shows another embodiment of the invention. As shown in the figure, the lower part of the rod-shaped gateball goal post 6,
A sensor 7 for detecting contact of the ball 5 is fixed to the outer peripheral surface of the ball 5 . There is no particular limitation on this sensor 7, but in this case, a pressure sensing element is the simplest and most suitable. A detector 8 and a notification means 9 are placed on the top surface of the goal post 6. Of these, the detector 8 is connected to the goal post 6.
It operates when the sensor 7 detects that the ball 5 has come into contact with the ball 5. Further, the notification means 9 is driven by the detector 8, and when the ball 5 contacts the goal post 6, it emits sound and light, or either sound or light, to notify the entire contact. That is, the configurations of the detector 8 and the notification means 9 are the same as those of the detector 3 and the notification means 4.

Although there is no particular limitation on the power source in the embodiments of the present invention, solar cells are suitable considering the fact that gateball is played outdoors in principle.The first and second embodiments of the present invention Figures 3 and 4
A more detailed explanation will be given based on the block diagram shown in the figure. As shown in FIG. 3, infrared rays emitted from a light emitting section 2a consisting of an infrared light emitting diode that emits infrared rays are normally transmitted to a light receiving section 2a consisting of a phototransistor sensitive to infrared rays.
The light is received at b. When the light reception of the light receiving part 2b't' is blocked by the ball 5, the detection circuit 1° is activated by the signal, and the one-shot multivibrator 1 for relayed jeep is activated.
1 is activated. As a result, the audio 1-layer LSI 12 operates for a predetermined time, and the low frequency amplifier circuit 13 operates.
and a fanfare etc. via the speaker 14, the ball 5
A sound is played to announce the passage of. At the same time, a light emitting diode 16, which is a light notification means, is made to blink via a driver 15. At this time, the detection circuit 10 is formed of a comparator so as to send out an output signal only when a signal equal to or higher than a predetermined threshold is input in order to prevent malfunction. In addition, the output of the speech synthesis LS112 is connected to the terminal 17.
may optionally be transmitted to other transmitters (not shown) or the like.

FIG. 4 is a block diagram corresponding to the second embodiment of the present invention, which differs from the block diagram shown in FIG. 3 only in that the sensor 7 is constituted by a pressure sensitive element. i.e. sensor 7
When the ball 5 comes into contact with the ball 5, a signal is sent to the detection circuit 10, and thereafter it functions in the same way as in the case of FIG.

In addition, in the above embodiment, the detectors 3 and 8 and the notification means 4 and 9
is integrally fixed to the gate 1 or the goal post 6, but it does not necessarily have to be integrally formed if the signals from the sensors 2 and 7 are transmitted remotely.

As specifically explained above in conjunction with the embodiments, according to the present invention, it is possible to objectively know that the gateball ball has passed through the gate and touched the goal post.
Not only can troubles caused by misjudgments be avoided, but the game can be made more interesting by selecting the notification method.
