Description

Saddle Movable Indoor Bicycle Exercise Device

The present invention relates to an indoor bicycle exerciser that allows the user to rotate by pedaling the bicycle indoors, and in particular, the indoor bicycle exercise unit, especially the saddle moves by comparing the user's actual exercise speed with a preset exercise speed. It is a saddle-movable indoor bicycle exerciser that can increase the target achievement rate by exercising, and makes it possible to exercise with excitement.

In general, bicycles are used for pedaling to quickly move to a destination by rotating wheels, and general bicycles are used for riding on roads, parks, and mountain roads. In other words, indoor bicycle exercisers are used.

The indoor bicycle exerciser performs exercise according to the exercise speed he thinks while referring to the speedometer under the load condition set by the user. In the indoor bicycle exerciser, even if the user's exercise speed is out of the range of the user's thinking speed, there is no problem in continuing the exercise.

In the conventional indoor bicycle exerciser, only load conditions can be set, and setting and feedback on the exercise speed are impossible. For example, if your speed is outside of your own set speed or range of speed, you should continue to watch the speedometer to increase or decrease your speed and get automated feedback from the indoor bike exerciser. There is no way.

Accordingly, in order to obtain a consistent exercise intensity and exercise amount in the recurring exercise schedule, only the active and continuous will of the user should be expected, and thus, there is a very difficult problem in setting and maintaining a consistent exercise intensity and exercise amount. In a conventional indoor bicycle exerciser, it is difficult to set a goal and feedback for achieving a consistent goal.

In particular, the use of indoor bicycle exercisers in the field of exercise test or rehabilitation exercise is more prominent.

The exercise load test is a cardiovascular information that can not be obtained in a stable state to detect cardiac-related diseases through exercise, and the maximum and submaximal exercise performance is largely tested using a treadmill and an indoor bike. Evaluate. When using a bicycle, the load goes up according to the time set for each protocol, but the rotational speed (movement speed) requires that a specific rotational speed (mostly 50 to 70 RPM) be set for each protocol. However, in the indoor bicycle, the feedback mechanism for maintaining the specific rotational speed is weak, and therefore, the inspection cannot be performed by accurately adjusting the predetermined rotational speed, and thus the reliability of the inspection is inferior.

In the rehabilitation exercise, it is desirable to exercise at a predetermined exercise intensity. Although it is possible to set and maintain the load condition, it is difficult to accurately manage and maintain the exercise speed (speed).

Therefore, the carriage block 25 can be initially located in the center of the base member 20 by the rear start position sensor 24c and the front start position sensor 24d.

When the carriage block 25 moves forward or backward and is detected by the front limit sensor 24a or the rear limit sensor 24b, the motor 31 stops so that the carriage block 25 and the bicycle moving part no longer fall. Will not.

The display device 17 performs an input / output function with a user and functions as a control device, and is provided with a setting unit 17b for setting an exercise speed such as an exercise load and a pedal rotation speed, and the main body 10. Speed detection unit 17c for detecting the movement speed through the Hall sensor 18, a motor control unit 17d for adjusting the rotational speed and direction of the motor 31, and a display unit for displaying the set movement speed and the actual movement speed A control unit 17a for controlling the motor controller 17d and displaying motion information on the display unit 17e by comparing the information of the setting unit 17b with the information of the speed detecting unit 17c. Include. In addition, the speed detection unit 17c may further include a warning generation unit (not shown) for generating a warning sound or an encouragement sound when the movement speed detected by the speed decreases from the set movement speed.

The saddle-movable indoor bicycle exerciser of the present invention configured as described above, when rotating the pedal of the bicycle exercise part in a state in which the exercise speed and the pedal rotation speed are set in advance, the actual movement speed and the set motion detected by the hall sensor In preparation for speed, if the actual speed is slower than the set speed, the bicycle movement part is pushed backward. If the actual speed is faster than the set speed, the bicycle part moves forward. Thus, the user can exercise while having an interest, and it is easy to achieve the exercise goal. Also, when the pedal is pushed back, the pedal should be rotated at a speed faster than the set speed to return to the original position, and when the pedal is moved forward, the pedal should be rotated at a speed slower than the set speed to return to the original position. The difference with the set exercise speed may be accumulated (integrated) and appear as the position of the bicycle exercise unit, and in order to return the bicycle exercise unit to its original position, it may be controlled to compensate for the difference of the accumulated exercise speed. Accordingly, it is possible to automatically compensate for the difference in exercise speed.

Although described and illustrated with reference to some embodiments for illustrating the technical idea of the present invention, the present invention is not limited to the configuration and operation as described above, the scope of the technical idea described in the claims Those skilled in the art will appreciate that many changes and modifications can be made to the invention without departing from the scope of the invention.
