Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to sports balls, especially lifting in soccer games, or the number of times the ball is kicked until it hits the ground or the length of time the ball stays in the air, such as in the traditional Japanese game of Kemari. Regarding exercise balls that are ideal for competitive games.

PRIOR TECHNOLOGY Traditionally, lifting the ball, which is a skill of soccer players, is an exercise in which one player hits the ball against the top of the foot, knee, chest, forehead, etc., and holds the ball without letting it fall to the ground. When adopted as a game and compete for the number of times the ball is kicked until it falls, the time the ball is held, and the time it stays in the air, humans must count the number of times the ball is kicked. In particular, it is impossible to convert technical difficulties such as ball retention time and flight time per inning into points based on individual players' judgment unless a separate measurer is assigned.

Furthermore, even if the A1 surveyor is evaluated, the main cost is involved in determining the difficulty of the technology, making it difficult to objectively evaluate it.

Furthermore, in the case of temari, which is a game for young children, it is difficult for the child to count the number of movements while exercising, and it would be extremely convenient if the number of movements could be automatically counted.

Purpose of the Invention The present invention has been made in view of the above circumstances.The ball itself has an external force automatic counting means built in, automatically counts the external force applied to the soccer ball, and further improves the difficulty of exercise technique. By converting performance into numerical values and displaying them, the objective is to enable objective evaluation of skills and to allow players to concentrate on the competition.

Structure of the Invention The exercise ball according to the present invention includes a detection means for detecting an external force applied to a pole, such as a pressure sensor, a detection signal from the detection means, and a numerical information signal related to the external force, such as a signal indicating the external force applied. It is equipped with calculation means for converting the number of times and the time interval between two external forces into information converted into points, a display means for displaying these information, and a battery wt source for driving each of the above means, all of which are built into the ball. It is something.

Embodiment In FIG. 1, (1) indicates an exercise ball, which is formed into the size of a soccer ball when used for a lifting competition. (2) is an air injection valve, (3)
(4) is a circuit unit, and (4) is a pressure sensor that serves as a detection means.These are placed in a position opposite to the valve (2), and their weights are adjusted so that they are balanced.1. 'j will be adjusted. That is, generally the weight of the valve (2) is about 8 to 92 mm, while the weight of the valve (2) is about 8 mm to 92 mm;
Since the additional weight of 6) and the pressure sensor (4) is about 15 to 201 grams, a balancer (5) is attached to the valve (2) side, and the weights of both are set to be substantially equal. .

FIG. 2 shows the surface of the ball (1), and (6) is a display panel which is the surface portion of the circuit unit (6), on which numerical information to be described later is digitally displayed. This circuit unit (6) is embedded in the ball (1), and its surface is
matched to the surface of the ball (1). (The force is an elastic bush that closes the battery compartment. (8) is a hole equipped with a switch, and (9) is a hole equipped with a buzzer. Both are embedded inside the hole (81 (9). The structure is designed so that no external force is directly applied to them.

FIG. 3 shows the display surface of the display panel (6), and in the case of this embodiment, two types of information are displayed alternately, for example, at one-second intervals. That is, the numerical values shown in the figure (a) represent the number of times of lifting, and the numerical values shown in the figure (b) represent the value obtained by adding the difficulty to the number of times of lifting and converting it into a score. Here, the difficulty refers to the quality of the ball (1) in each kick, that is, the flight time, and this is converted into a signal by detecting the time interval from the first kick to the next kick. As this time interval increases, the score increases in a geometric progression, as shown in Figure 9.

FIG. 4 shows the circuit unit (6) and this unit
), thin, low power consumption display panels such as electrochromic display panels can be used. Here, as a liquid crystal display panel, spacer R particles are mixed with liquid crystal,
A panel having a flexible structure as a whole is suitable, and thereby the impact resistance of the display panel can be improved. When using a highly engineered chromatic display panel, the strong IW can be improved by using a solid electrolyte and making the entire structure a solid structure. (11

This is done via a contact member (not shown) provided on the side wall of the battery storage hole (14). (6
), L S I no), etc. As the elastic material, rubber or elastic synthetic resin is used. A hard material is suitable for the resin (13). In addition, instead of resin (1→), it is also possible to use a rubber material such as silicone rubber. In this case, such a rubber material may be filled into a hard container and used together with the container. (7) is a battery storage The aforementioned elastic bushing seals the hole (14) and can be made of the same material as the protection 1-(Ife), and when it is press-fitted, acts to press the battery (15) against the substrate (11) below. .

The elastic bushing (7) has a protrusion αη formed around it, which is connected to the concave groove (
It has a structure that allows it to fit within one day and not come off easily. (
1 layer consists of resin (1 size) and protective layer (holes (8 holes connected to IQ)
) is a rod-shaped switch installed inside the power switch,
Counting reset 71 - acts as a switch with multiple functions such as a switch. This switch (1c! is buried to prevent external force from being directly applied to it) is made of 4 structures.

Therefore, it is necessary to use a thin rod-like object for this operation. Discrimination between multiple functions can be performed by the number of operations, and the design is such that one operation turns the power on and off, and two consecutive operations turn the power on and off. Qo is a display window made of a transparent elastic material, and a space (21) is provided between this display window and the display panel (6) in order to further relieve the external force applied to the panel (6). (2) is formed in the holding-IW (It,) and the hole (9

), the electrical contact 041 is formed on the bottom of the
This is a protrusion formed on the side surface of 1f9.

Next, the ball (1) side will be explained. 05) is a rubber tube, 2) is a thread-wound layer formed around the outer periphery of this tube (C), (A) is an intermediate layer made of rubber, and I2→ is made of natural leather or synthetic leather. This is the epidermal layer. (29
) is a bowl-shaped container whose bottom surface is made of hard resin glued to a tube (c), and (to) is an elastic body formed on the side surface of the container C from the top end to the skin J0 (c).

The circuit unit (3) described above is press-fitted and fixed into the bowl-shaped container (a). That is, the protective layer (Protrusions (protrusions) of IfS engage with the grooves G31) of the elastic layer 00) and the circuit unit (
6) is made difficult to come off, and at the same time, by forming the opening end on the ball side narrowly, its fixation is strengthened.

In order to make it even more difficult for the circuit unit (3) to come out from this opening, a structure may be added in which a plurality of rubber strips are bridged in the opening and thereby hold down the circuit unit (3).

5 to 7 show specific circuits and signal waveforms of the circuit unit 1-(3) and the sensor (4). In FIG. 5, (4) is a strain gauge type pressure sensor and a driver circuit, specifically a constant t5 pressure circuit. That is, when a lithium battery is used as the battery (10), its output voltage is approximately 3.0 V, but the voltage decreases over time, and on the other hand, the pressure sensor (4) is driven and the ball (1) is To accurately detect pressure changes within the
This is because a constant voltage of ˜2.0 μ is required. The pressure sensor (4) detects changes in the air pressure inside the ball (1), and when the ball is kicked, an impact pulse P is obtained inside the ball and in its output. This pulse corresponds to a kicking ball motion, and its pulse height is proportional to the impact intensity.

The signal R in FIG. 6 represents this, and the voltage 0 corresponds to the internal pressure of the ball (1) (approximately 0.45 kLi/ca). (31 is a comparator, the signal R is applied to the ■ side terminal, and the constant voltage voltage ■ is applied to the other 0 side terminal.
The reference voltage ■l+ obtained by dividing variable resistor 0119+trowel
is applied. This reference voltage (1) is higher than the voltage (2) and is used to remove noise or weak impact pulses from the sensor (4).For example, the minute pulse y shown in signal PI (Fig. 6) is Shut off at comparator (35). In this way, a significant impact pulse is output to the output terminal of the comparator.
shows a clock pulse waveform output from an oscillator Gη (FIG. 7), which will be described later.

FIG. 7 shows an example of a signal processing circuit, where 0→ is an AND gate to which pulse R is input at one end, 0 is a counter for the number of times a dark output is added to this AND gate, and (4 is a counter for the number of times a dark output is added). With the country's output as one input, the number of times is "1"
A comparator whose other input is a signal corresponding to , outputs a high level signal when both inputs match, that is, when the output of the counter 0 is 1''. This H level signal is transmitted to the electronic sound generation circuit (41) first stage circuit (4
1i) and drives it. Electronic sound generation circuit (41
) is divided into four stages of circuits, and the first stage circuit (41i) is
Continuous sound signal with constant time width, second stage circuit (41ii)
is an instantaneous single sound signal, 6th stage Q (4]ii+)
outputs an intermittent sound signal, and the fourth stage circuit (41iv) outputs a continuous sound signal having a constant time width. These four-stage circuits (41
Each output signal from the electronic sound generation circuit (41) consisting of i) to (4xiv) is applied to the driver circuit IQ+43 via the OR gate (4a) to sound the buzzer (44).

(4Q is the output of the AND gate (3→) and the comparator (40
) is an AND gate that generates a signal obtained by inverting the output of the circuit via an inverter (incorporated), and its output is input to the second stage circuit (41ii) of the electronic sound generation circuit (41). (B) is an oscillator that generates a clock pulse CP, and this pulse CP is input to the counting terminal of the time counter (B) via an AND gate (47). When input, it outputs a reset signal and a set signal immediately after that, and a time counter (4 times are added.
First, the count contents are cleared by the reset signal,
The next set signal makes it possible to count. This reset and set signal is output in synchronization with the clock pulse CP. (50) is an arithmetic circuit that receives the output of the time counter decoy and executes the following predetermined arithmetic operation.

y=(α・hair)β...(1) Here,
α and β are regular patterns, α>10 and β≧1. Also,
This is the period from the first pulse & to the (i+1)l pulse R, and is within the range of 0.05 sOe≦Ti (3,0 sec. The value of Y represents the score, and the period '■ If the value is large, the value increases in a geometric progression.The curve is shown in Figure 9. (51) is a latch circuit, (5'4 is an adder, and an arithmetic circuit (50 The calculation result obtained by is added to the memory contents of the latch circuit (51), and the result is stored in the launch circuit 1).In this way, the latch circuit (5]) stores up to the i-th The total number of scores is held, and it is integrated via the adder (translation) every time the i,101th score from 51 is output.(5:+) is the generator Cdη The divider 64) which receives the output pulse CP of CP and divides the frequency into the signal II-h uses this 1 signal switching signal, and the score from the latch circuit 51 (51) as the input signal of nh is the number of times the 1a signal breaks. A display content switching circuit manually operated by the number of times information signal from the counter C39) outputs the score information signal and the number of times MiV lid signal alternately in 1) Iz period according to the switching signal. A driver circuit which receives a signal or a score information signal and obtains a display drive axis value, (f) is a display panel. G59) is a comparator that inputs the time signal from the disaster, No. 1, and doubles the time set as the maximum period (No. 8 and inputs C). When the relationship % is satisfied, it is determined that the state is normal and the output is multiplied by L(4) level. In this embodiment, this time period is set to "3 seconds". , for the following reasons: In general, in ball lifting competitions, the period from the first impact to the second impact corresponds to the height of the ball being kicked up, and Because it requires a high level of skill to keep hold of the ball,
This period (T) cannot be indefinitely long, and is based on the assumption that, judging from the skill level of a normal player, the maximum is about 16 seconds. This comparator (
! ] [phase] is input to the sixth stage circuit (41iii) of the electronic sound generation circuit (41), and at the same time, it is manually inputted to the AND gate (g) (471) via the NOR gate ((to)). .From this, after the pulse R is output, if the pulse & is not output after the time TO has passed, the output of the comparator (59) changes to the "blasphemy level" and the output of the no game -'-1-(GO
) is inverted to the Yj'' level, and the output of the C AND gate (al
l) (, 171 is the cutoff σ. In such a case, an indication indicating that the time is over, a rule violation, etc. It is necessary to control so that the contents of the time counter 4, which has been incremented until reaching il, are not transferred to the arithmetic circuit I().
Using the signal from 4, when the i+1 1111th pulse arrives, the i+
This can be achieved by configuring to perform calculations based on the contents of the 0 bar of the time counter counted during the period up to the first pulse generation time.

(61) is a comparator that takes the time signal π from the time counter as the input signal phase and inputs it based on the time signal set as the minimum period, and when the relationship T≧1 is satisfied, , determines that it is in a normal state and obtains "υI level a@" at its output. In this embodiment, this time 1 is 100
It is set to 5 seconds. This is due to the following reasons. In other words, if the period of impact before and after is extremely short, if the ball falls to the ground and bounces naturally, or if the kicking effect is kept extremely low and the number of times is increased. This is because this is considered to be the case where the user intended to do so, and the criterion time is set to 1005 seconds. If the time 5 is smaller than this reference time l, the output of the comparator H6Cl changes to the high level, so the output of the gate H6Cl is inverted by °C, and the AND gate (3→(4η) is cut off. As a result, both the number counter (3) and the time counter (1→) stop their counting operations.

In addition, in the figure, the arrow indicated by (R) indicates a reset signal,
[4] occurs when the above-mentioned switch (10) is operated and when the power is turned on.

Next, the operation of the circuit will be explained. In the initial state,
All circuits are in the reset state, and the comparator ←9) (6+
Since the outputs of l are both at the ゛υ° level, it is a no-game −＋−
(The output of a+J is "1, so the AND gate (g) 0
η is in the open state i). In such a state, the ball (
1) By applying an external force such as a kick to the ball, the first shot is fired!・If pulse P2 is generated, this pulse P
2 is input to the number counter (39) and the time counter 08, respectively, through 4η. The first stage circuit (41i) of the electronic sound generation circuit (41) is activated, and a continuous sound having a certain time width is emitted. This electronic sound means the start. The count signal of the number counter C30 passes through the driver circuit (5''6
, and the number of times 1 is displayed on the display panel (FA) at a 1-second cycle.Next, when the second impact pulse P2 is input, the number of times counter (the content of the plow changes to 2 degrees.At this time, Since the two outputs of the comparator (40) do not match, its output changes to the '°C° level, and therefore the output of the inverter (40) changes to the '°C° level.
6) The output is ``G'' and the AND gate (both of the two human powers are ``G'', and the output is M'. This ``explosion level signal'' causes the second stage circuit of the electronic sound generation circuit (41) to (
41ii) made! IjIJ, and an instantaneous single sound is uttered. This means that external force is applied for the second time or later. The second weight of Innovak 1-Pulse R is the time counter (
When inputted to 4→, the contents of the count up to the time of inputting this pulse are inputted to the next stage arithmetic circuit 0), and the score conversion as described above is executed. Initially, the memory content of the latch circuit (c) 1) is zero, so this calculation result is stored in the adder (latch circuit ←l via the circuit), and this score information is sent to the display content switching circuit (54). The numerical value °'2 which is the content of the number counter (30) and the score are given to the display panel (5 → From then on, each time an impact pulse & is added, the contents of the number counter 09) are incremented by 1, and the contents of the time counter (field 4) are processed through the arithmetic circuit (50) and are combined with the score information.
7, the latch circuit β]) is integrated by 1.

After the impact pulse & generation, if the homogeneous pulse ratio of time `Ih (3 seconds) does not arrive, the output of the comparator (59) changes to "off", closes the AND gate country 0η, and repeats the number of times. Counter (39) and time counter (1→) are prohibited from sending counting signals, and at the same time
The stage circuit (4] 1ii) is activated to emit a continuous sound having a certain time width. This electronic sound means that the time has expired or that a rule has been violated.

On the other hand, if the ball falls to the ground after the competition and its bounce is attenuated, the pulse interval of the impact pulse R will gradually become shorter, and this interval will be equal to time - (0
, 05 seconds), the output of the comparator (611 changes to 0), passes through the Noah gate ← 0, and closes the AND gate (3 [0 (47). The number counter (Sakaki) and the time counter (4→ counting are prohibited, and at the same time, the fourth stage circuit (41
tv) is activated, and a continuous sound with a certain time width is emitted. This electronic sound means the competition is over.

In this way, the number of lifting times alternately displayed on the display panel and the difficulty level are added to them.

A J-riding competition will be held based on the highest score.

Although the initial purpose is achieved by the above-described circuit configuration, similar processing can actually be performed by a microcombiner. This will be explained using the program flowchart shown in Figure @8. klt lvA'
When a start is applied by a button or the like, the arithmetic section, the writing section, etc. are first reset.

It is determined whether or not the impact pulse P2 is input when the pulse ratio is 1-1. If the pulse ratio is present, a start sound which is a continuous sound is emitted. Subsequently, the time counter starts counting time. In the next step, the counted time is compared with the longest reference time, and if it is determined that -≧', it is determined that the time has exceeded, and a rule violation is indicated by generating an intermittent electronic sound. After the electronic sound is generated, the state returns to the initial state. If the impact pulse R of @2 shots is input again within the period in which the condition <11 is satisfied, the counting of the time counter is stopped, and this time the counting time is 1) and the minimum reference time is 1! A comparison is made with ITh, and if it is determined that RI≧1, that is, normal, a single electronic sound is generated, and the number of times N
An addition of °′1°□ is performed to On the other hand, if it is determined that Ti(Th), it is determined that the competition is over, and the number of times and scores up to that point are displayed, and at the same time, the end notification sound is emitted, and the state returns to the initial state.As described above, it is determined that i≧1, and the number of times After the counting is executed, the score calculation is executed.This is done using the above-mentioned equation (1), and then the CAfJ is also executed. After going through the ratio processing, the contents of the time counter are set to 1~ and the process returns to the step of starting time counting again.Such processing is repeatedly executed depending on the human power of the impact pulse, and the number of times is added. A score calculation is performed.

Effects of the Invention According to the present invention, the ball itself has a built-in detection means for detecting an external force applied to the ball, and a means for counting and displaying this detection signal, so that the player can exercise by himself. There is no need to count the number of times, and you can concentrate on the competition. Further, according to the present invention, since the height of the kicked ball is converted into a score and displayed, it becomes possible to objectively evaluate the athletic technique, and for example, it is possible to evaluate the lifting technique of a soccer player. It can be used as Further, the hole according to the present invention is suitable as a play ball for young children who cannot count satisfactorily. Furthermore, lifting competitions or kemari-like competitions using balls according to the present invention do not require a large playing area and can be played by just one person, so they can be enjoyed as easy sports.
