TECHNICAL FIELD The present invention relates to a physical fitness training apparatus.

BACKGROUND ART Conventionally, as a physical fitness training apparatus of this type, there is a physical training apparatus that simply pedals a stationary bicycle indoors to strengthen physical strength, mainly muscle strength. Load is constant,
There is no change in the atmosphere and scenery, it is a pain for the trainee to start training, it is difficult to maintain the training for a long time, and there is a problem that such excessive exercise is not a preferable method in terms of exercise physiology.

[Object of the Invention] The present invention has been made in view of the above points, and an object of the present invention is to provide physical strength capable of reasonably performing moderate exercise according to the physical strength of a trainee. To provide a training device.

Disclosure of the Invention (Embodiment) FIGS. 1 to 10 show a bicycle as an embodiment of the present invention. In this embodiment, a pulse (heartbeat) is set to a predetermined set value during physical training of a human. This is in accordance with the theory of exercise physiology that the purpose can be achieved most effectively by continuing the exercise of such intensity that is continued before and after.

FIG. 1 is a block diagram schematically showing the overall configuration,
Like a normal vehicle, a propulsion mechanism by human power, a propulsion mechanism by power of a motor 5, a pulse measuring means for measuring the pulse rate of a person who performs physical fitness training, and a pulse rate measured by the pulse measuring means are set in advance. The difference between the target pulse rate, the rate of increase of the pulse rate per hour, the acceleration of the physical fitness training apparatus main body 1, and the load magnitude of the physical fitness training apparatus main body 1 immediately before are used to determine the load magnitude of the physical fitness training apparatus main body 1 at the present time. The calculation means for determining and the load adjusting means for changing the magnitude of the load of the physical fitness training apparatus main body 1 by the output of the calculation means are provided, and the entire control system, measurement or signal detection system, and physical fitness training apparatus. Body 1
A secondary battery 8 is used as a power source of the motor 5 that serves as a power source of. First, the pulse measuring means for measuring the pulse of a person (hereinafter, referred to as an exerciser) A who performs physical fitness training will be described. The microphone 2 is attached to the chest, temples, arms, and other parts of the exerciser A where heartbeats are easily heard, so that the exerciser A's heartbeat can be measured. The exerciser A, to which the heartbeat microphone 2 is attached, manually drives the physical fitness training apparatus main body 1 to propel the physical fitness training apparatus main body 1. The heartbeat sound picked up by the microphone 2 is amplified by an amplifier having high sensitivity and low noise to measure the pulse. Further details of the pulse measuring means are as follows.
Although the method of transmitting the output of the pulse measuring means to the calculating means of the physical fitness training apparatus main body 1 described later is simply performed by wire, it is excellent in reliability, but a second power supply is provided for pulse measurement, and this power supply and the pulse are used. The measurement circuit section and the transmission section are separated from other parts and carried by the exerciser A, and the other circuit parts and the receiver are attached to the physical fitness training apparatus main body 1, and these 2
By connecting the divided circuit parts with a wireless signal, the freedom of movement of the exerciser A is increased, and the comfortability of the exerciser A can be improved. Here, a method of wirelessly transmitting the pulse data of the exerciser A to the calculation means of the physical fitness training apparatus body 1 will be described. Figure 6 shows exerciser A
FIG. 7 is a block diagram showing a circuit configuration of a transmitter 28 mounted on the body and a receiver 29 mounted on the physical fitness training apparatus body 1, and FIG. 7 picked up by the microphone 2 attached to the exerciser A ( The pulse sound shown in a) has a weak signal strength and contains a lot of noise, and it is difficult to distinguish the pulse sound from the noise. Therefore, in the preamplifier circuit 10, once the microphone 2
A pulse sound is extracted as shown in FIG. 9B by amplifying the output and applying a narrow band filter 11 that passes a frequency component that strongly appears when frequency analysis is performed on a general human pulse pulse. Since the signal level is attenuated when passing through the narrow band filter 11, the signal is amplified again by the main amplifier circuit 12. By comparing the output of the main amplifier circuit 12 with a predetermined value in the level comparison circuit 13, it is converted into a rectangular pulse signal as shown in FIG. The oscillation control circuit 14 operates with the output of the level comparison circuit 13, and the oscillation circuit 1
At 5, the signal is converted into a predetermined pulse signal shown in FIG. Since the transmitting antenna 16 and the receiving antenna 17 of the receiving unit 29 are separated by only about 1 m, it is possible to sufficiently transmit and receive even a weak radio wave. The received signal received by the receiving antenna 17 is shown in FIG.
As shown in (e), the waveform is buried in external noise. After the received signal is amplified by the preamplifier circuit 18,
Further amplification is performed by the narrow band amplification circuit 19 that amplifies only the frequency band near the oscillation frequency on the transmission side. The output of the narrow band amplifier circuit 19 is shown in FIG. The output of this narrow band amplification circuit 19 is detected by the detection circuit 20.
The detection output corresponding to the pulse sound shown in (g) is obtained. Then, the output of the detection circuit 20 is further compared with a predetermined value by the level comparison circuit 21 to obtain the rectangular wave pulse shown in FIG. By inputting this pulse into the counting circuit 22, a pulse (x ₁ ) per unit time is obtained, and this pulse (x ₁ ) is obtained.
The increase rate (y) of the pulse per unit time is obtained by using, and is input to the calculating means as an input of the function together with other factors such as the acceleration α and the magnitude of the load (Pi). In addition to the method of directly measuring the pulse with the microphone 2 as described above, the measurement of the heartbeat is performed by detecting and amplifying the change in the electrical characteristic in the part of the human body which changes in response to the heartbeat. There is also a way to do it.

Next, the calculation means will be described. First, a schematic description will be given. According to the physical strength of the exerciser A, a pulse is set in advance as a target pulse (x ₀ ). Then, the pulse (x ₁ ) of the exerciser A and the target pulse while driving the body training apparatus 1
(x ₀ ) difference (x), and the time derivative of the pulse (x ₁ ) at the time of measurement,
That is, the rate of increase of the pulse (y) is calculated, and the magnitude of the load on the physical fitness training apparatus main body 1 is calculated from the above two values (x) and (y). This calculation means performs calculation for obtaining an appropriate load size frequently with a minute time interval.
In each calculation, the magnitude of the immediately preceding load (Pi) is one factor that determines the magnitude of the load at the next moment (Pi ₊₁ ) in order to prevent bad riding comfort due to a sudden change in the load. More specifically, the magnitude of the load (Pi) immediately before the load is changed to a level that is sufficiently faster than the rate when the heart rate of the human body suddenly changes, and does not significantly deteriorate the riding comfort. Sa (Pi ₊₁ ) to decide the influence. A factor that determines the uncomfortable riding comfort is a sudden change in the acceleration α of the physical fitness training apparatus body 1. Therefore, this acceleration α is also input to the function calculation for the calculation of the above-mentioned calculation means. The reason why the acceleration α is one factor of the function is that the sudden change in the acceleration α of the physical fitness training apparatus body 1 appears as uncomfortable physical fitness training of the exerciser A and lack of safety. Further, by using the acceleration α as a factor for the calculation of the calculation means, a shocking load is applied to the motor 5 and the generator 6 whose operation is controlled by the output of the load adjusting device 4 which will be described later, and this can be prevented by shortening the life of the device. There is also an effect. Arithmetic means output when summarizing the above described equation becomes _{Pi +1 = f 1 (x)} + f 2 (y) + f 3 (α) + Pi.

The output of this calculation means is input to the load adjusting device 4, and the load adjusting device 4 makes the heartbeat of the exerciser A appropriate, that is, the intensity of exercise is appropriate for the exerciser A, and the physical fitness training apparatus main body. The load of 1 is adjusted. For example, even if a person approaches an uphill slope during physical fitness training, as a result of the load adjustment, the exercise amount required for the exerciser A to propel the physical fitness training apparatus body 1 does not differ from that in the case of traveling on a flat ground, and is propelled by the motor 5. The force is added to the force for propelling the physical fitness training apparatus main body 1 of the exerciser A to propel the physical fitness training apparatus main body 1. Similarly, when downhill originally,
Even if the exercise amount of the exerciser A is zero, the physical fitness training apparatus main body 1 should be running, but the load adjusting device 4 operates the generator 6 to request the propulsive force of the exerciser A,
The amount of exercise is constant.

Here, the adjustment of the propulsive force by the motor 5 is performed, for example, in the case of a DC motor, the time τi in which the power of the secondary battery 8 is applied to the motor 5 and the time τ in which the power of the secondary battery 8 is not applied to the motor 5. ₀ is frequently generated alternately, and time τi,
This is done by changing the ratio of τ ₀ . When an AC motor is used as the motor 5, the amplitude of the motor drive power source (not shown) is changed.

Further, the load of the physical fitness training apparatus main body 1 is adjusted by the generator 6 by adjusting the time τi for charging the secondary battery 8 with the generator 6.
Then, the time τ ₀ during which the generator 6 is idled is generated alternately with high frequency, and the ratio of the time τ i, τ ₀ is changed. The adjustment of the ratio of the times τ i and τ ₀ is performed by adjusting the time interval for turning off and turning on the semiconductor switch.

FIGS. 2 (a) and 2 (b) show how the load of the physical fitness training apparatus main body 1 proportionally increases / decreases in accordance with the output of the load adjusting apparatus 4, and at the same time when traveling on a flat road and climbing a slope. Even when the load of the physical fitness training apparatus 1 itself changes during traveling and the output of the load adjusting device 4 is the same, the generator 6 is operating during traveling on a flat road, but the propulsion by the motor 5 is exercised during traveling uphill. The state in which it is combined with the force of the person A and becomes the propulsive force of the physical fitness training apparatus main body 1 is shown.

When the physical fitness training apparatus main body 1 of the present embodiment is used as a practical vehicle (such as a two-wheeled vehicle), the switch SW is switched to the accelerator 9 side to cut off the load adjustment function and the exerciser A can arbitrarily set the accelerator 9. Due to
The power supply to the motor 5 is changed to adjust the speed of the physical fitness training apparatus body 1 as a practical vehicle.

The operation of this embodiment will be described with reference to the flowchart shown in FIG. First of all, do you use it as a practical vehicle,
Select whether to use it as a fitness training device. When used as a physical fitness training device, a regenerative deceleration load rate and a target pulse (x ₀ ) are set. The regenerative deceleration load rate allows the magnitude of the load to be changed according to the physical strength of the exerciser A even when running at the same speed. In addition to the load required to drive the physical fitness training apparatus body 1, the load generated by the generator 6 is added. Even if the same speed is maintained, even if the physical strength is required to be stronger, that is, even if the output of the load adjusting device 4 is the same, the physical fitness of the exerciser body 1 can be increased according to the physical strength of the exerciser A. Is set.

During physical training, measure your pulse rate (x ₁ ) and measure this pulse rate (x ₁ )
Based on, the difference (x) from the target pulse (x ₀ ) and the rate of increase (y) of the pulse (x ₁ ) obtained by time-differentiating the pulse (x ₁ ) are obtained. And pulse (x ₁ )
Is greater than the target pulse rate (x ₀ ), that is, when the difference (x) is less than or equal to zero, an alarm is issued to notify that there is a danger to the human body. The acceleration α is calculated simultaneously with the calculation of the rate of increase (y) of the pulse. Next, it is determined whether or not this acceleration α is the acceleration of the human body, that is, the exerciser A, and it is determined whether or not the speed of the body training apparatus main body 1 is reduced. At this time, if the acceleration is due to the human body, the magnitude of the load is not changed in order to smooth the acceleration α and increase comfort. When the exerciser A does not promote the physical fitness training apparatus main body 1, that is, when the exerciser A is resting, the load is adjusted mainly according to the pulse of the exerciser A. For example, if exerciser A's pulse (x ₁ ) is the target pulse (x ₀ )
When the pulse increase rate (y) is extremely high, the motor 5 propels the physical fitness training apparatus main body 1 even if the foot of the exerciser A is in a rest state, Run 1 without decelerating. On the contrary, when the pulse (x ₁ ) is small, the physical training apparatus main body 1 decelerates with the legs of the exerciser A resting, and the deceleration urges the athlete A to move his / her feet silently.

The change in the load of the physical fitness training apparatus main body 1 is obtained by the output of the load adjusting device 4 as shown in FIGS. 2 (a) and 2 (b). The output of the load adjusting device 4 is related to the pulse. The difference (x) between the measured pulse rate (x ₁ ) and the target pulse rate (x ₀ ) is related by a proportionally changing function. This is like the start of physical training, pulse (x ₁ )
If is far from target pulse (x _0), the load is heavy, when approaching the target pulse (x ₀₎ is because the work to lighten the load so as not to exceed the target pulse (x _0). On the contrary, the rate of increase (y) of the pulse is related by an inversely increasing relationship, which is to prevent the exerciser A from exercising rapidly and having an unfavorable result in physical fitness training. is there. In other words, this is to increase the physical strength while keeping the stress on the human body soft. Therefore, when the exerciser A makes a rapid exercise despite the physical fitness training apparatus meeting the above purpose, for example, when the pulse (x ₁ ) exceeds the target pulse (x ₀ ) as described above. Deal with it by issuing an alarm. When the exerciser A is rowing to accelerate or prevent deceleration, the amount of exercise is calculated and stored together with the pulse at that time. This record will be useful for looking back and examining the physical strength of exerciser A.

The exercise amount of the exerciser A is calculated as follows. For example, the fourth
As shown in FIGS. (A) and (b), the pedal 30 and the pedal 30
The first stopper 33a is attached to the arm 32 that connects the front wheel gear 31 that is rotated by the exerciser A's stepping, through the pressure-sensitive element 34, and the force applied by the arm 32 causes the pressure-sensitive element to move. The arm 32 and the pressure sensitive element 3 so as not to damage the armature 34.
A cushioning material 35 is provided between the above and the above. In addition, a second stopper 33b is provided on the opposite side of the first stopper 33a to the front wheel gear 31.
The arm 32 is prevented from moving in the direction opposite to the direction in which the pedal 30 is depressed. In this device, the force detected by the pressure sensitive element 34, the rotation angle of the arm 32,
The amount of exercise of the exerciser A is calculated based on the length of the arm 32. The front wheel gear 31 and the rear wheel gear 50 are connected to the chain 3
Connected at 6.

Alternatively, as shown in FIG. 5, a push-down gear 37 and a push-up gear 38 for pushing the width of the chain 36 are meshed with both sides of the chain 36, and the both gears 37, 38 are supported by the support 3
9, a push-down spring 40 and a push-up spring 41 are housed between the gears 37, 38 and both ends of the support 39, and the push-down spring 4 is attached to the push-down spring 40 side.
There is one in which the pressure sensor 42 is mounted so that one end of 0 contacts. An amplifier circuit 44 that amplifies the output of the pressure sensor 42, a smoothing circuit 45 that smoothes the output of the amplifier circuit 44, and a rotation speed counting circuit 4 that counts the rotation speed of the push-down gear 37.
7. A momentum calculation section 43 including a rotation speed counting circuit 47 and a multiplication circuit 46 that multiplies the outputs of the smoothing circuit 45 to obtain a momentum is provided. The output of this momentum calculation unit 43 is recorded in the recording unit 48. In this case, the force for pushing down the push-down gear 37 is detected by the pressure detection sensor 42, and the momentum is calculated from this force and the rotation speed of the push-down gear 37. Fig. 5
(b) is to detect the force exerted by the exerciser A by the force to push the chain 36 apart.
The description is omitted because it is almost the same as in FIG. Fig. 5
In (a), the force applied by the exerciser A is replaced by the force detected by the pressure sensor 42, but in the case of the push-down gear 37, it can be detected by the amount of contraction of the push-down spring 40.

When the exerciser A's pulse rate (x ₁ ) approaches the target pulse rate (x ₀ ), power is supplied to the motor 5 in order to reduce the exercise amount of the exerciser A, as shown in FIG. 5 (a). To the gear 51
Meshes with the teeth 25 attached to the inside of the wheel 24, the force of the motor 5 is transmitted to the wheel 24, and the force of the motor 5 causes the wheel 24 to rotate, so that the exerciser A pedals the pedal 30. Added to power.

Next, the operation of changing the weight of the load shown in FIG. 1 will be described. The rate of increase of the pulse rate received per unit time (y) is also
The acceleration α of the exerciser A does not change, and the case where only the pulse rate (x ₁ ) is small and the case where it is large will be described. When the pulse (x ₁ ) is small as shown on the left side of FIG. 8 (a), the input signal of the load adjusting device 4 which has been function-calculated becomes high level, and conversely as shown on the right side of FIG. 8 (a). When it is too high, the input signal of the load adjusting device 4 becomes low level. When the signal level of the input signal of the load adjusting device 4 is equal to or higher than a predetermined value, power is supplied to the electromagnetic clutch 23 so that the electromagnetic clutch 23 is engaged so as to drive the generator 6, and power is supplied to the motor 5. Be stopped. On the contrary, the load adjusting device 4
When the signal level of the input signal is less than a predetermined value, the power supply to the electromagnetic clutch 23 is stopped and the motor 5
Power is supplied to. Although not shown, the above operation is performed by an electric circuit built in the load adjusting device 4. Therefore, when the left side of FIG. 8 (a) drives the generator 6, the load of the physical fitness training apparatus 1 becomes heavy, and when the right side of FIG. 8 (a), the amount of exercise of the physical fitness training apparatus main body 1 is increased. Act to be more. That is, in the latter case, the electromagnetic clutch 23 is disengaged and the generator 6
Is stopped, and on the contrary, the power training device main body 1 is also propelled by the motor 5 because power is supplied to the motor 5. Therefore, the load of the physical training device main body 1 seen from the exerciser A is lightened. Looking at the operation of the load adjusting device 4 with respect to the secondary battery 8, as shown in FIG.
(x ₁ ) is small, the exerciser A is in a charged state while pushing the physical fitness training apparatus main body 1, and if the pulse (x ₁ ) increases, the burden on the exerciser A is lightened. Therefore, the secondary battery 8 is discharged. As described above, according to the magnitude of the output of the load adjusting device 4, power is supplied to the motor 5, or conversely, power is supplied to the electromagnetic clutch 23 so that the electromagnetic clutch 23 meshes. Shown in Figures (a) and (b). The above is a description of how the load adjusting device 4 works depending on the amount of the pulse (x ₁ ), that is, whether the difference from the set value of the target pulse (x ₀ ) is large or small. Similarly for (y), the load adjusting device 4 operates so that the exercise amount of the exerciser A decreases as the rate of increase (y) of the pulse increases.

The physical fitness training apparatus of this embodiment is characterized in that it can be run outdoors so that physical training can be enjoyed and that physical training can be carried out while looking at the scenery. The wheels 24 are floated to allow free rotation, and the magnitude of the load is changed by using only the generator 6 as a load, so that the same effect as in the case of outdoor traveling can be exhibited. As an example, FIG. 10 shows a case where the exerciser A depresses the pedal 30 and turns the wheels 24 to perform training while the present apparatus is kept stationary, for example. At this time, the load of the physical fitness training device 1 is determined by a mechanism for charging the secondary battery 8 with the output of the generator 6 rotated via the gear 52 meshed with the teeth 25 inside the wheel 24. The weight of the load is determined by the charging operation duty setting unit 26 determined by the output signal level of the load adjusting device 4 shown in FIG. That is,
When the charging duty is small, the number of idle states of the generator 6 increases and the load becomes light. By changing the charging operation duty in this way, it is possible to realize a load corresponding to the physical strength and pulse of the exerciser A, and it is possible to perform physical strength training similar to that in the case of actual running while in a stationary state.

Since the load adjusting means uses the generator as the load increasing element and the power propulsion mechanism as the load reducing element to change the load of the physical fitness training apparatus main body, the pulse measuring means is used. The pulse is measured, the magnitude of the load applied to the body of the physical fitness training apparatus is determined from the pulse and the acceleration of the physical fitness training apparatus in the calculation means, and the load adjusting device generates power as a load increasing element according to the output of the calculation means.

Physiologically favorable training can be realized.
Moreover, there is also an advantage that, in a normal daily life without training, it is not treated as troublesome as this kind of physical fitness training apparatus used only indoors.
