Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to karate, taekwondo, kung fu, kick boxing, boxing, kendo,
The present invention relates to a device for determining an effective hit of a batting type martial arts such as fencing, and more particularly to an improvement of an effective hit determination device which does not require a cable between a competitor and a referee device for transmitting a determination signal of an effective hit.

[0002]

2. Description of the Related Art In batting martial arts such as karate, taekwondo, kung fu, kick boxing, boxing, kendo, and fencing, hitting a predetermined part of an opponent's body in a predetermined manner becomes an effective hit and is limited. Which of the predetermined number of valid hits is taken first in a time is a competition which is a criterion for determining a win or loss.

[0003] Of these, for example, in karate competition, there are three types of rules, a squeeze rule, a light contact rule, and a full contact rule. This is a rule that, if touched, is an offense. The light contact rule is a rule in which light strikes using karate armor are not a foul but only violent strikes are a foul. Furthermore, the full contact rule is a rule that does not take any offense by hitting using karate armor.

[0004] In competitions conducted under these rules, when a thrust or kick is attacked, the presence or absence of an attack by an attacker,
That is, at present, the judge judges whether or not there is an effective hit by visually checking.

However, in an actual competition, the speed of a thrust and kick attack is high, so that it is difficult for even an experienced judge to visually confirm it. JP-A-63-240890 as a detector
Has been proposed.

[0006]

However, such a conventional striking detector is designed to determine in advance the striking force which is not required to be an offense, the striking force which requires attention, or the striking force which is to be considered an offense. Above the set threshold, there is a problem that only a constant warning signal can be generated in all cases, and the impact force cannot be quantitatively detected.
Further, there is a problem that there is much noise between the transmitter and the receiver.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and two different electrodes are arranged at an appropriate interval on an object to be hit to form a sensor for detecting an effective hit. A conductor is provided on the surface of the tool, and when the hitting tool comes into contact with the hitting object at a predetermined contact pressure or higher, the two electrodes provided on the hitting object are short-circuited to form the hitting object. Effective hit determination device for batting martial arts, such as karate, that can detect and determine the effective hit accurately without detecting the impact force applied to the player and without depriving the competitor of freedom or giving danger The purpose is to provide.

[0008]

Means for Solving the Problems To achieve the above object, an effective hit judging device according to the present invention is provided with two hitting objects such as a body protection armor such as a body protector or a head protection armor such as a menho.

The surface of a hitting tool such as a fist supporter, a sport tabi or a foot supporter is provided with a conductor made of a conductive material, and the hitting tool is disposed on the hitting target when the hitting tool comes into contact with the hitting target. The striking force applied to the striking object is detected by short-circuiting the two electrodes, and the detection signal is transmitted to the information transmission device to determine an effective striking according to the striking force, and to determine the effective striking. A signal is transmitted to the central device by radio waves, and the effective hit is determined and displayed in the central device.

Further, the effective hit judging device according to the present invention is characterized in that
A ridge is provided between the two electrodes to detect only a striking force equal to or higher than a predetermined contact pressure as an effective striking.

[0010] Further, the effective hit judging device of the present invention is characterized in that:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an effective hit judging device according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a hitting target body 3 composed of a body protection armor 1 such as a body protector, and FIG. 2 shows a hitting target body 3 composed of a head protection armor 2 such as a menho. At a predetermined position on the surface of the hitting target body 3, two different electrodes 4, 5 are disposed at appropriate intervals, and the sensor 6 for detecting an effective hitting as a whole is provided. The detection sensor 6 is provided at a location that is regarded as an effective surface in the karate competition or the like.

When the two electrodes 4 and 5 are attached to the hitting target body 3 composed of the protective armor 1 and 2, for example, a printing process may be performed directly on a predetermined portion of the surface of the hitting target body 3,
Alternatively, a copper foil or the like may be attached to a predetermined location on the surface of the impact target body 3. Note that the hitting target body 3 including the protective armors 1 and 2 is formed as an insulator.

FIG. 3 shows a striking hitting tool 7 such as a competition glove, a fist supporter or the like, and FIG. 4 shows a kicking striking tool 8 such as a sporting soccer or a foot supporter. A conductor 9 made of a conductive material is provided on the surface hitting portions of these hitting tools 7 and 8.
The conductor 9 can be formed, for example, from a woven fabric or the like woven with a thread or the like coated with a conductive dye or the like.

In a game such as karate, when the hitting tools 7 and 8 come into contact with the hitting target 3, the conductor 9 short-circuits the two electrodes 4 and 5 disposed on the hitting target 3 to cause the shorting. The striking force applied to the striking object 3 is detected. The detection of the impact force can be performed, for example, by simply setting the conductor 9 of the impact tool 7, 8 to the two electrodes 4, 5 if the two electrodes 4, 5 are flat.
Even if the player touches lightly, short-circuiting may easily occur, or short-circuiting may occur due to the sweat of the competitor, and the effective striking force cannot be accurately detected.

In the present invention, in order to prevent such an ineffective impact force from being detected, as shown in FIG.
A ridge 10 is provided between two different electrodes 4 and 5, which are disposed at a predetermined location on the surface of the device at a proper interval. The provision of the ridges 10 allows the conductors 9 of the hitting tools 7, 8 to be lightly contacted with the target 3 to be blocked by the ridges 10 and the two electrodes 4.
5 is not in a short circuit state. Similarly, the sweat of the competitor
The electrodes 4 and 5 are not short-circuited because they are blocked by the ridges 10.

Thus, between the two electrodes 4 and 5,
Since the ridge portion 10 is provided, if the impact force (depth of impact) exceeding a predetermined contact pressure is not applied, the electrodes 4, 5,
There is no short circuit between them, and it is detected as an effective hit and is not determined. By appropriately adjusting the height of the ridge portion 10, the range of the impact force as an effective hit can be appropriately selected.

Since the protruding portions 10 are provided around the two electrodes 4 and 5, they also have a role of protecting the electrodes 4 and 5 from repeated strong striking forces. The ridge portion 10 is formed of an insulating material such as rubber.

In the effective hit judging device of the present invention, by providing the above-mentioned ridge portion 10, conditions for effective hitting, such as hitting speed, strength, and accuracy of hitting an effective surface, are secured. However, in order to ensure the accuracy of the effective hit,
A predetermined contact time between the two electrodes 4 and 5 is detected, and only a striking force equal to or higher than a predetermined contact pressure is detected and determined.

The effective hit judging device according to the present invention includes the provision of the ridge 10 and the detection of a predetermined contact time at the time of hitting, as well as the detection of the resistance value between the respective electrodes. The strength of the force is determined, and it is detected and determined more accurately as an effective hit.

The information transmission apparatus 11 shown in FIG. 6 performs the above-mentioned determination work, and comprises an input section 12, a microcomputer (logical operation) section 13 and a transmission section 14, and includes a body protection armor 1 and a head protection arm. A detection signal from an effective hit detection sensor 6 provided on the hitting target body 3 composed of the armor 2 is input to the input unit 12 and the microcomputer (logical operation) unit 13 to determine an effective hit. From the central unit 15 of FIG.

In the information transmission device 11, first, in the input section 12, the resistance value between the electrodes 4 and 5 is detected and determined. For example, when a thrust or a kick from the hitting tools 7 or 8 is given to the effective surface of the hitting target body 3, if the hitting force is strongly applied, the resistance value falls on a large area and the resistance value decreases. By utilizing this, the contact pressure is detected from the width of the contact surface, and the effective hit is determined.

Next, the microcomputer (logical operation) section 13 detects and determines the contact time between the electrodes 4 and 5. For example, when a thrust or a kick from the striking tool 7 or 8 is applied to the effective surface of the striking object 3, conduction between the electrodes 4 and 5 is continuously obtained for a certain time, for example, 10 mm. If it is, it is detected and determined as an effective hit.

FIG. 7 shows the central unit 15, in which the effective hit determination information from the information transmission device 11 is transmitted by radio waves.
The signal is transmitted to two receiving units 16 and 17, for example, the receiving unit 16 for the red corner and the receiving unit 17 for the green corner. The central unit 15 includes the receiving units 16 and 17, a microcomputer (logical operation) unit 18, a display unit 19, a microcomputer (logical operation) unit 20, and an operation unit 21 as an infrared remote control main body. Reference numeral 23 denotes a commercial power supply or a power supply including a rechargeable battery.

In the microcomputer (logical operation) section 18,
A determination of competing is made. For example, when the information on the effective hit is transmitted from the information transmission device 11 of one of the competitors in the red corner to the receiving unit 16, the validity of the red corner is displayed on the display unit 19 via the microcomputer (logical operation) unit 18. Displayed as hits. Then, within 40 mm seconds set in advance, for example, as a competing, the determination information of the valid striking from the information transmitting apparatus 11 of the competitor in the other green corner is received by the receiving unit 17.
Is transmitted in this case, it is determined that the hitting is performed, and the effective hitting of the green corner is displayed on the display unit 19 via the microcomputer (logical operation) unit 18.

A microcomputer (logical operation) unit 20 and an operation unit 21
Functions as a judge system in the operation of the competition, for example, it controls and displays the score of each competitor, timer display of the competition time, etc. Is displayed for the purpose of understanding.
