The present invention relates to a treadmill. More particularly, the present invention relates to a treadmill and a method of controlling the treadmill that can adjust the rotational speed of the treadmill according to a user's traveling speed.

Modern people live a relaxed life in busy, busy daily life. In addition, people living in modern times are increasingly lacking in exercise due to the development of industrialization and the rapid development of scientific civilization, resulting in various diseases. Under these circumstances, a treadmill has been developed, which is an indoor exercise equipment that allows running or walking exercise in a narrow indoor space for modern people who are easy to neglect.

In general, a treadmill is a device designed to achieve a motion effect such as walking or running in a limited indoor space, and the user runs on a belt that is rotated by a motor.

Such a treadmill needs to adjust the speed according to the user's basic physical condition and the amount of exercise. For this purpose, it is common to control the running speed by adjusting the speed of the motor through the keypad operation on the control panel.

Speed control device of a conventional running machine to adjust the speed of the motor as described above is a touch speed control method, a fixed speed control method by a program in the control panel, a control method by ultrasonic, by attaching an optical sensor to the handle There is a control method by, but in the case of the control method by the key in the control panel, the user has to operate the key of the control panel during high-speed operation, there is a problem that has a great risk in safety, in the case of the method by the program Can not change the speed at will, and only exercise at the programmed speed, so the user cannot adjust according to the physical condition of the user (eg, basic fitness and time and amount of the exercise progressed), and the excessive exercise proceeds. Or, there was a problem that the exercise effect falls.

In consideration of the above problems, the recently introduced ultrasonic control method is composed of a transmitter, a receiver, and an ultrasonic sensor unit, which is very complicated and requires a separate power source, and an adjustment terminal for matching transmission and reception frequencies with an ultrasonic sensor. Due to the nature of the ultrasonic wave, there is a problem such as the complexity of the structure and the increase in manufacturing cost, such as the accuracy is lowered due to the basic error according to the temperature.

In addition, the method by the optical sensor has to input the detection signal by touching or touching the part where the optical sensor is installed, but it may be somewhat safer than the operation of the keypad. There is a problem with the operational risk due to the reduced concentration.

In addition, in the case of the conventional treadmill, when the user does not reduce the speed in the state where the speed is not adjusted, the safety accidents such as losing the balance of the body and falling down are likely to occur.

The display unit 34 may have various structures such as a lamp or a buzzer. When the visual warning is given through the lamp, a red lamp is activated when the belt 13 is accelerated, and a blue lamp when the belt 13 is decelerated. Is operated so that the user can easily distinguish it.

Hereinafter, a process of controlling the speed of the belt 13 of the treadmill 10 will be described with reference to FIG. 4.

In using the treadmill 10, the user first operates the switch 31 of the operation panel 17 to turn on the treadmill 10 to activate the operation panel 17, and then automatically adjusts the speed of the belt 13. Select whether to use the automatic setting mode to adjust to the treadmill or other modes provided by the treadmill 10, for example, the speed or time momentum setting mode or various driving modes. (S100 ~ S110)

When the automatic setting mode is selected, the rotational speed of the belt 13 is adjusted according to the traveling speed of the user as described below, so that the rotational speed of the belt 13 can be adjusted to the traveling speed of the user.

When the user selects the automatic setting mode as described above, the deceleration line to be used as the acceleration line 27 and the deceleration detection unit 28 to be used as the acceleration detection unit 27 among the plurality of lines installed on the footrest 11 of the treadmill 10. Set the line (S120 ~ S130).

The line setting selects any one of the plurality of acceleration lines 20, 21, 22 of the plurality of acceleration lines 20, 21, 22 located in front of the footrest 11, and the user sets a gap on the foothold 11. One of the acceleration lines 20, 21, and 22 of the three acceleration lines 20, 21, and 22 disposed as the acceleration sensing unit 27 is set.

To this end, the operation panel 17 is provided with a switch 31 for selecting a desired line from a plurality of lines.

Similarly, the user operates the switch 31 of the operation panel 17 to decelerate any one deceleration line (23, 24) of the plurality of deceleration lines (23, 24) located behind the scaffold (11). 28).

In the following description, for convenience of description, a case in which the third acceleration line 22 and the first deceleration line 23 are set as shown in FIG. 2 will be described as an example.

When the acceleration line 22 and the deceleration line 23 constituting the acceleration detecting unit 27 and the deceleration detecting unit 28 are set, the acceleration line 22 is formed from the front end of the scaffold 11 to the acceleration section. The deceleration line 23 set at the rear end of the scaffold 11 forms a deceleration section, and a constant speed section therebetween.

When each line is set, the driving motor 15 is operated to rotate the belt 13, and the user runs at a constant speed on the belt 13. (S140 ~ S150)

As such, the piezoelectric element 26 set in the acceleration line 22 continuously detects whether or not the user's load is applied in the course of the constant speed driving of the user according to the rotation of the belt 13, and when the load is detected. The controller 30 increases the rotation speed of the belt 13 by controlling the driving motor 15. (S160 ~ S170)

That is, when the user's traveling speed is changed and accelerated, the running speed is relatively higher than the rotation speed of the belt 13, so that the user moves to the front of the footrest 11.

When the user moves to the front of the scaffold 11 and reaches the acceleration section, the user presses the acceleration line 22 set in the acceleration section while driving, and the load of the user is accelerated on the scaffold 11 through the belt 13. 22 to the piezoelectric element 26.

The piezoelectric element 26, which senses the load of the user, sends an output signal to the detection unit 29, and the detection unit 29 detects which piezoelectric element 26 the signal is from and applies it to the controller 30. do.

In addition, the controller 30 confirms that the rotation speed of the belt 13 is lower than the current driving speed of the user and applies an output signal to the motor controller 33.

Accordingly, the motor controller 33 controls the driving motor 15 according to the output signal of the controller 30 to increase the rotation speed of the belt 13.

When the rotation speed of the belt 13 is gradually increased, the user is gradually moved to the rear of the footrest 11 by being pushed by the rotation speed of the belt 13 to reach the constant speed section beyond the acceleration section.

When the user reaches the constant speed section, the detection signal is not emitted from the piezoelectric element 26 of the acceleration line 22. Therefore, the controller 30 rotates the belt 13 at a corresponding speed, and the user can travel at a constant speed.

On the other hand, when the user's running speed is changed and decelerated, the running speed is relatively lower than the rotation speed of the belt 13 so that the user moves to the rear of the footrest 11.

When the user moves to the rear of the footrest 11 to reach the deceleration section, the user depresses the deceleration line 23 set in the deceleration section while driving and the user's load is installed on the footrest 11 through the belt 13. 23 is applied to the piezoelectric element 26.

The piezoelectric element 26, which senses the load of the user, sends an output signal to the detection unit 29, and the detection unit 29 detects which piezoelectric element 26 the signal is from and applies it to the controller 30. do.

The controller 30 confirms that the rotation speed of the belt 13 is higher than the driving speed of the current user through the signal, and applies the output signal to the motor controller 33.

Therefore, the motor controller 33 controls the driving motor 15 according to the output signal of the controller 30 to lower the rotation speed of the belt 13. (S180 to S190).

When the rotational speed of the belt 13 is gradually lowered, the user gradually moves to the front of the footrest 11 to reach the constant speed section out of the deceleration section.

When the user reaches the constant speed section, the detection signal is not emitted from the piezoelectric element 26 of the deceleration line 23. Therefore, the controller 30 rotates the belt 13 at a corresponding speed, and the user can travel at a constant speed.

The process is repeated continuously to immediately modify the rotational speed of the belt 13 according to the user's running speed.

On the other hand, when the controller 30 determines whether a signal is applied from the piezoelectric element 26 installed in the stop line 25 in the process of adjusting the rotation speed of the belt 13, the load of the user from the piezoelectric element 26 is determined. If it is detected immediately stops the drive motor 15 to stop the rotation of the belt (13) (S200 ~ S210).

That is, when the user is pushed to the rear of the footrest 11 to step on the piezoelectric element 26 of the stop line 25 located at the rear of the footrest 11, the piezoelectric element 26 detects the load of the user and this signal. Is applied to the detection unit 29.

The detector 29 confirms that the signal comes from the piezoelectric element 26 of the stop line 25 and sends it to the controller 30.

The controller 30 stops the rotation of the belt 13 by stopping the driving motor 15 through the motor control unit 33.

When the automatic setting mode is selected as described above, the running machine 10 can be operated in a state in which the rotation speed of the belt 13 is automatically adjusted according to the user's traveling speed, and the user stops the switch after completing the desired exercise ( When the 31 is operated, the rotation of the belt 13 is stopped while the driving motor 15 is stopped. (S220 to S230)

As described above, according to the present invention, the rotational speed of the belt is automatically adjusted to the running speed of the user without any manipulation, so that the treadmill can be driven at a desired speed during use.

In addition, it is possible to run at a desired speed to easily adjust the amount of exercise and to prevent excessive exercise of the user, it is possible to prevent accidents caused by not matching the speed of the belt in advance.

In addition, by stopping the belt automatically when the user moves out of the exercise area, by preventing the fall from the belt it is possible to prevent the occurrence of safety accidents and increase the safety of the treadmill.
