Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pace checker.

[Conventional technology]

Wristwatches are widely used as portable timekeeping devices, and along with the computerization, they have many functions and are compatible with various purposes. It has been developed as a timer, stopwatch and pacemaker for sports. In competitions where distances are displayed at regular intervals over long distances such as marathons, the lap time is measured and the slow speed relative to a preset time is displayed. Many things have been developed considering that it can run at the speed of.

[Problems to be Solved by the Invention]

However, conventional pacemakers, etc., are only for athletics, and none seem to have been developed considering for underwater sports such as swimming. In the case of a swimming race, a pacemaker such as a buzzer for a wristwatch is useless and the swimmer cannot hear it at all. I always use my arm to keep water,
Like when you hold your arm up like you did at track and field,
Since it is not possible to press buttons, etc., it is very inconvenient and useless in the present wristwatch. In practice, I want to set the pace, but there is no suitable pacemaker, and I will rely on the coach's screams (useless because I can not hear), but in self practice it was completely raised .

[Means for Solving the Problems]

When swimming, there is almost nothing to wear, and it is at most paddle (watering). The paddle is for reinforcement and cannot be handled freely.
Not normally used. After all, the watch for underwater seems to be the most familiar.

In order to obtain a pacemaker in water, the present invention provides an oscillator,
It has a frequency divider, a counter, a digital display and an external operating member, has a memory circuit for storing the time measured by the external operating member, and has a repeat function for repeatedly measuring the set time. In addition, a repeat counter for counting the number of repeats is provided, and the count time and the number of repeats are displayed on the digital display.

〔Example〕

FIG. 1 is a circuit block diagram of an embodiment of the present invention. The pace checker includes an oscillator (1), a frequency divider (2), a counter (3), an external operation member (4), a memory circuit (5), a digital display (6), a repeat counter (7), and a repeat circuit. (8), repeat count memory circuit (9), coincidence detection circuit (10) distance setting memory (11), arithmetic circuit (1
2), composed of a changeover switch (13).

The signal generated by the oscillator (1) is frequency-divided by the frequency divider (2) to be frequency-divided into a signal suitable for the purpose of timing. (In the present invention, it is appropriate to obtain a clock of 1/100 second.) The frequency-divided signals are counted by the counter (3), and the counter (3)
A signal is sent from the digital display (6) to the digital display (6), and the signal is processed by the decoder to display the time.

The external operation member (4) is used for the purpose of starting, stopping, resetting the counter (3), setting the time count, setting the number of repeats, setting the distance, and switching the display. The measured time is set and stored in the memory circuit (5). The coincidence detection circuit (10) is a circuit for detecting a coincidence between the time measured by the counter (3) and the time measured by the memory circuit (5), and when the coincidence is detected, a signal is sent to the repeat circuit (8). The repeat circuit (8) resets the counter (3) in response to the signal from the coincidence detection circuit (10), and subsequently outputs a signal for starting the counter (3). Meanwhile, it sends a signal to the repeat counter (7). The repeat counter (7) counts the signals from the repeat circuit (8), the changeover switch (13) and the arithmetic circuit (12).
Send a signal to. The repeat count memory circuit (9) is a circuit for setting the repeat count by the external operating member (4) and is connected to the arithmetic circuit (12). The distance setting memory (11) is a circuit for storing distance data set by the external operating member (4) and is connected to the arithmetic circuit (12). The arithmetic circuit (12) is a circuit for arithmetic operation. In the present embodiment, the counter (3) is turned on by the signals of the repeat counter (7) and the repeat count memory circuit (9) when the two values match. It has a function to convert distance by issuing stop signal and repeat counter (7) signal and distance setting memory (11) signal. Repeat counter (7), repeat count memory circuit (9) ,
It is connected to the distance setting memory (11) and the changeover switch (13). The changeover switch (13) is a repeat counter (7)
And a switch for receiving a signal from the arithmetic circuit (12) and the external operation member (4), switching the signal to display the repeat circuit or the distance, and sending the signal to the digital display (6). The digital display (6) is a display for receiving the signals from the counter (3) and the changeover switch and displaying the time and the number of repeats or the distance. The operation of this embodiment will be described below.

Suppose you want to swim 400 meters in a 25-meter pool and want to swim 25 meters at a 23-second pace. There are 15 turns, but I would like to check 16 times at each 25 meters. The clock time is set to 23 seconds and the number of repeats is set to 16 times. When starting by the external operation member (4), time counting starts by the counter (3). The counter (3) is of addition counting type. In the case of swimming, even if the pace checker is attached to the wrist by a wristwatch system, the display can be seen only at the moment of turn. (This is also difficult with backstroke) Looking at the display when turning after swimming 25 meters, if it is faster than the set pace,
The number of repeats is 0, and the time display is a number smaller than 23 seconds. If it is late, the number of repeats is 1, and the time count display is the time count after the first reset. The same thing can be said for marathons and swimming, but the self-paced pace of runners and swimmers does not fluctuate significantly;
Since the pace fluctuation of swimming 50 meters is at most a few seconds,
There is no problem unless you set the pace incorrectly. Further, since the pace setting is a target, it is set 1 to 2 seconds earlier than the self-actual pace, so in the case of the present embodiment, which is reset each time,
The number that appears when you turn should be 1 repeat and the time display should be 1 to 3 seconds. Even if the number of repeats is 0 and the time display is 21 seconds, the function as a page checker is sufficiently fulfilled. Next, turn 50 meters (the second turn) and look at the display section, which shows that the number of repeats is 2 and the counting time display is 1 to 3 seconds. The pace checker is reset every 23 seconds, and the repeat count is added up each time. After the fifteenth turn, the number of repeats becomes 15, and the clock time display also shows 1 to 3 seconds (or 4 to 6 due to fatigue).
It may be seconds), so I will do my best for the last 25 meters at full speed. Similarly, if the pool is 400 meters in a 50-meter pool, you can set the number of repeats to 8 at a pace of 46 seconds.

The distance setting memory (11) is used when displaying the number of repeats as a distance display. In the case of the above-mentioned explanation example, if the distance setting is set to 25 by the external operation member (4), the number of repeats and the set distance are multiplied. The selected number {calculated by the arithmetic circuit (12)} is switched by the changeover switch (13) and displayed. That is, 25, 50, 75 ...

The effects of the present embodiment are as follows: (1) Since the timekeeping time display is reset at every set time, it can be confirmed at a slow speed relative to the set pace. In many cases, it is displayed with a delay from the set pace, and at most one-digit seconds are displayed, so reading is easy even when confirmation is possible only for a short time.

(2) Since the number of repeats is displayed, it is not necessary for the swimmer (or runner) to count each time, and there is no mistake.

(3) You can check the pace yourself, practice alone, and set the pace yourself, so you can exercise according to your physical condition.

(4) Since the distance, the number of times, and the pace can be freely set, the pace can be set according to the place. (23 seconds at 25 meters, 10
(Turn or 200 meters, 26 seconds, 5 rounds, etc.) FIG. 2 is a circuit block diagram of another embodiment of the present invention.
Basically, it is the same as the first embodiment, only the counter (14) and the arithmetic circuit (16) are added, and the function of the memory circuit (15) is changed accordingly, so the first embodiment The same functional parts as in the example are omitted. The counter (14) is connected to the frequency divider (2) and counts the signal from the frequency divider (2). The start / stop operation is performed by the external operation member (4). It is also connected to the arithmetic circuit (16),
The counting result is processed by the arithmetic circuit (16) and the changeover switch (1
It is displayed on the digital display (6) via 3). The calculation circuit (16) has a function of calculating one interval when the time count and the number of repeats are set by an external operation member and storing it in the memory circuit (15), and the set measurement time and the counting result of the counter (14). And has a function of calculating the difference. The operation of this embodiment will be described below.

Let's say you want to swim 200 meters in a 25 meter pool in 3 minutes and 20 seconds. 20 hours can be set with an external operating member
If you set 0 seconds and the number of repeats to 8, the arithmetic circuit (16)
Is calculated as 200 seconds / 8 times = 25.00 seconds / time, and the pace of 25 meters is stored as 25.00 seconds in the memory circuit (15). If started by the external operating member (4), the same operation as in the first embodiment is performed. When the swimmer finishes the swim and then makes a stop operation, the arithmetic circuit (16) reads the time measured by the counter (14), compares it with the set time, and calculates the difference in speed. The result is switched by the changeover switch (13) and displayed as plus or minus * seconds. Unlike the counter (3), the counter (14) is a counter for the total time from the start operation to the stop operation.

The effect of this embodiment is the same as that of the first embodiment, and further (1) the pace can be set only by setting the total time and the number of repeats.

(2) Since the set total time (timed time) and the measured time are compared and calculated and displayed, not only the split but also the slow speed with respect to the target time can be known.

The digital display should be as large as possible, but the wristwatch system has a limit on the size of the display and it is a switching display with a display with a large number of digits (total time set, result display), A dot matrix system that can freely change the display size is suitable.

In addition, it is appropriate to blink the display unit to call attention to the last one repeat, and this can be easily done by calculating the last one by the arithmetic circuit (12) and switching the display. The blinking at that time is suitable for a cycle of 0.2 to 0.3 seconds.

〔The invention's effect〕

 The present invention has the following effects.

(1) It is possible to easily slow down the set pace.

(2) You can see the number of repeats and concentrate on the pace distribution, so the practice effect is improved.

(3) Since you can check the pace by yourself, you can practice alone without the need for a pace allocation coach.

(4) The number of repeats and pace can be freely set according to the desired distance.

As described above, the pacemaker of the present invention is most suitable for exercise exercises, is particularly effective for swimming exercises, and has a great practical effect.
