The present invention relates to a hula hoop (10) capable of calculating the amount of motion (kcal) using the pressure sensor 12 and the principle of the gear.

By using the ratio of the gear, that is, the ratio between the waist circumference of the human body and the inner circumference (circumference) of the hula hoop 10, the number of rotations of the waist (N) rotated by the user can be measured. Allow calories to be calculated.

In the present invention, the accuracy of the rotation speed measurement of the user turned waist using the principle of the gear is more than 99%.

One embodiment of the present invention is applied to the hula hoop 10 formed on the inner circumferential surface of the acupressure protrusions 11 at equal intervals, the hula hoop 10 has a structure that can be separated and assembled into a plurality.

The hula hoop 10 according to an embodiment of the present invention is the input unit 13 for inputting the user's weight, waist size, time to exercise, exercise direction change notification time, exercise time, calorie consumption, waist And a display unit 14 capable of indicating the number of revolutions, and the like, a pressure sensor 12, a piezoelectric element 22, a control unit 15, and a power supply unit 16.

The input unit 13 is composed of a plurality of operation buttons 20 installed on one side of the hula hoop 10 so that the user can directly input the user's weight, waist size, time to exercise, exercise direction change notification time, Weight, waist size, etc. input by the operation button 20 can be confirmed through the display unit 14.

At this time, the user is able to input the exercise time to exercise in advance planned before turning the hula hoop 10, and when the specified time is completed so that the buff sound sounds.

In addition, the user is able to input a previously planned movement direction notification time before turning the hula hoop 10, which is to rotate the hula hoop 10 by the buffing sound when the movement direction notification time is completed. Provide the opportunity to change.

Since the hula hoop (10) movement in one direction for a long time can cause spinal diseases, to prevent this, after a certain time to prevent the disease caused by the exercise by changing the direction of movement by buffing sound For sake.

The pressure sensor 12 is composed of first to fourth pressure sensors 12a to d installed in the circumferential direction in order on the inner circumferential surface of the hula hoop 10, and each pressure sensor 12 is touched. By measuring the rotation distance of the hula hoop 10 in contact with each pressure sensor 12 can measure the number of rotations (N) of the waist turned by the user.

At this time, the first to fourth pressure sensors 12a to d are provided at intervals of 90 degrees along the circumferential direction on the inner circumferential surface of the hula hoop 10.

The pressure sensor 12 also serves to inform the start of the movement and the direction of movement.

For example, when the hula hoop 10 is rotated counterclockwise, when the first pressure sensor 12a and the second pressure sensor 12b adjacent to each other are continuously touched, the buff sounds and the motion is detected through the direction recognition. Inform the start, the timer 18 is operated to increase the exercise time.

In addition, when the hula hoop 10 is turned clockwise, when the first pressure sensor 12a and the adjacent fourth pressure sensor 12d are continuously touched with respect to the counterclockwise direction, the buffing sounds and the movement is performed. It indicates that it has started, and the direction recognition indicates that the direction has been changed.

At this time, if there is no input of the pressure sensor 12 for 5 seconds, the exercise time is stopped. If there is a continuous touch before 5 seconds, the exercise time and the rotation speed of the waist are normally increased.

The control unit 15 includes an IC such as AMEGA8, CMOS 1411, etc. to perform calculations, and calculates the number of rotations of the waist, the time of exercise, the direction of the exercise, the movement direction notification time, the calorific value of the system of the present invention, and the like. In charge of overall control.

In general, calorie consumption is calculated as weight x exercise time x calories burned per hour (kcal).

However, the present invention applies the rotation speed of the waist turned by the user instead of the exercise time.

Because the amount of exercise may vary depending on whether you are exercising fast or slow, the number of rotations of the waist may vary for each person (assuming the same waist size) at the same time.

Therefore, the calorific value of the exercise calorie according to the movement of the hula hoop 10 of the present invention is as shown in Equation 1.

Exercise calorie (Q, kcal) = weight × number of rotations of waist (N) × calories burned per hour

In the above formula, the rotation speed N is the rotation speed of the waist turned by the user, and the amount of heat consumed per hour may vary depending on the diameter and weight of the hula hoop 10.

In the above formula, the method of obtaining the rotational speed N of the waist is applied to the principle of the gear.

That is, the user exercising using the hula hoop 10 rotates by engaging the inner circumference of the ring gear (the hula hoop 10 corresponds to the ring gear) and the outer circumference of the internal gear (the waist of the body corresponds to the internal gear). The same principle can be thought of.

In other words, the movement of the hula hoop 10 is to rotate the outer peripheral surface of the waist and the inner peripheral surface of the hula hoop 10 by friction when the user rotates the waist back or forth or oval.

The calculation method of the number of rotations (N) of the waist turned by the user is as follows.

When the first and second pressure sensors 12a and 12b of the first to fourth pressure sensors 12a to d mounted on the inner circumferential surface of the hula hoop 10 are touched by the waist of the body, the waist circumference of the body Since the surface passes through the first pressure sensor 12a and the second pressure sensor 12b, the rotation distance of the hula hoop 10 measured by the first and second pressure sensors 12a and b is the inside of the hula hoop 10. 1/4 of the circumferential length πd.

Subsequently, when the waist circumferential surface touches the third pressure sensor 12c, the rotation distance of the waist circumferential surface is 1/2 of the inner circumferential length of the hula hoop 10, and the waist circumferential surface is the fourth pressure sensor 12d. When touched) is rotated by 3/4 of the inner circumferential length of the hula hoop 10, when the waist circumferential surface touches the first pressure sensor 12a again, the rotation distance of the waist circumferential surface inside the hula hoop 10 One circumference of the circumference is made.

The controller 15 receives the detection signal from the first to fourth pressure sensors 12a to d to calculate the rotation distance of the hula hoop 10.

That is, when the hula hoop 10 rotates once, for example, the pressure sensor 12 includes the first pressure sensor 12a → the second pressure sensor 12b → the third pressure sensor 12c → the fourth pressure sensor. (12d) If the hula hoop 10 is touched by the waist in order, and the hula hoop 10 makes two turns, the rotation distance of the hula hoop 10 which is repeated by the user in the above cycle is turned to the "hula hoop 10. The inner circumferential length of πd × the number of revolutions (N ₀ ) of the hula hoop turned by the user.

After the rotational distance of the hula hoop 10 is measured by the pressure sensor 12, the rotational speed N of the waist rotated by the user is measured by using a ratio between the waist circumference of the user and the inner circumference of the hula hoop 10. Can be.

The rotational speed N of the waist turned by the user is expressed by the following equation.

At this time, N ₀ is the rotational speed of the hula hoop 10, d is the inner diameter of the hula hoop 10.

Therefore, the user can calculate the amount of heat consumed by the movement of the hula hoop 10 by substituting the rotational speed N value of the waist obtained by Equation 2 into Equation 1.

The display unit 14 is installed on one side of the hula hoop 10 to indicate not only the information input through the input unit 13, but also the time the user has exercised, the amount of exercise consumed, the rotational speed N of the waist rotated by the user, and the like. It consists of an LCD display panel.

The power supply unit 16 supplies power for the operation of the display unit 14 and the control unit 15, and consists of a battery and a storage battery, and the battery is initially used for the operation of the display unit 14 and the control unit 15. After that, the storage battery uses the piezoelectric element 22 mounted on the inner surface of the hula hoop 10 to store the power generated by the rotation of the hula hoop 10, and then applies power to the display unit 14 and the controller 15. do.

At this time, the piezoelectric element 22 is installed in the acupressure protrusion 11, and when the pressure is applied to the piezoelectric element 22 by the waist of the body during the movement of the hula hoop 10, electrical energy is generated by mechanical deformation.

An antistatic device or an antistatic spray 17 is mounted on the inner circumferential surface of the hula hoop 10. When the movement start is detected by the pressure sensor 12, the controller 15 operates the antistatic spray 17. By spraying the antistatic liquid, it is possible to prevent the sensor from malfunctioning due to static electricity.

At this time, the anti-static spray 17 may be mounted on the inner circumferential surface of the hula hoop 10, but when the production of the hula hoop 10 sprayed the anti-static spray on the inner circumferential surface of the hula hoop 10 after the hula hoop 10 May be sold to the consumer.

In addition, the hula hoop 10 is a separate type as shown in Figure 3, when the hula hoop 10 to remove the electric wire in the socket type connector 21 so that the electric wire inside the hula hoop 10 is not broken. Is connected.

Referring to the method of using the hula hoop 10 according to an embodiment of the present invention by such a configuration as follows.

First, the power switch installed in the hula hoop 10 is turned on to apply power to the display unit 14 or the like.

Subsequently, before turning the hula hoop 10, the user's weight, waist size, time to exercise, exercise direction change notification time, etc. are input by using the operation button 20 of the input unit 13 mounted on the hula hoop 10. .

Then, when the turning using the hula hoop 10, the first pressure sensor 12a and the second pressure sensor 12b mounted on the inner circumferential surface of the hula hoop 10 are touched by the user's waist and the buffing sound is generated. At the same time as the ringing exercise time begins.

At this time, the controller 15 receives the detection signal from the first and second pressure sensors 12a and 12b continuously and determines that the exercise has started, and sends an operation signal to the timer 18 to increase the exercise time. Be sure to

The control unit 15 calculates the user's exercise calorie value according to Equations 1 and 2 by using the pre-input diameter of the hula hoop 10, calories burned per hour, weight, and waist circumference, and exercises through the display unit 14. Indicate the exercise time and calories burned.

The control unit 15 is a time to change the direction of movement to the user by ringing a buffing sound through the buzzer 19 mounted on the hula hoop 10 when the exercise direction switching notification time is completed when the input of the movement direction notification time Inform.

In addition, when the time to exercise is input, when the time to exercise is completed, a buzzer sounds through the buzzer 19 to inform the user that the planned exercise time is completed.

The controller 15 determines that the movement is stopped when the detection signal is not input from the first to fourth pressure sensors 12a to d mounted on the inner circumferential surface of the hula hoop 10, and the pressure sensor (5 seconds before) If a continuous signal is inputted from 12), it is determined that the exercise is in progress, and the exercise time and the rotation speed of the waist are normally increased.

By the above method, when the user completes the hula hoop 10 movement, the heat dissipation amount, the number of rotations of the waist rotated and the exercise time are displayed through the display unit 14.

Therefore, in the present invention, if the user inputs the weight and waist circumference in advance without counting how many times the user directly turns the waist, the number of rotations (N) of the user rotated automatically through the display unit 14, the calorific value of the exercise and the exercise time exercised And the like can be displayed accurately.
