DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bicycle-type health device that performs exercise by applying a load to the pedals.By controlling the pedal load according to the rotation angle of the pedals, the dead center of pedaling is eliminated. It also changes the load applied to the left and right pedals.

Conventionally, bicycle-type health equipment, especially those that apply a load using mechanical brakes, have had the disadvantage that the moment of inertia of the rotating system is small, making it difficult to pedal at the dead center of pedaling, making it difficult to exercise comfortably. For this reason, some models have been equipped with a flywheel to increase the moment of inertia of the rotating system, but this has the drawback of increasing weight and making it inconvenient to move and transport.

FIG. 2 is a block diagram of the control system. Reference numeral 7 denotes a pulley connected to the pedal, and by means of this pulley and a belt 9 placed around the pulley 8, the rotation of the pedal is transmitted to the pulley 10 to increase the speed, and further transmitted to the motor 12 by the belt 11.

Magnet 1 is attached to pulley 7 and pulley 10.
3 and a magnet 14 are attached, and the rotation thereof is detected by a Hall element 15 and a Hall element 16 as detection devices, respectively. A pulse is output from the Hall element every time the pulley 7 and pulley 10 rotate once, and this output is input to the microcomputer 17. Microcomputer 1
7 performs calculations based on this input and outputs a control signal to a control device 18 that controls the load characteristics of the motor 12.

The rotation speed of the pulley 10 is an integral multiple of the rotation speed of the pedal 3. For example, if this speed increasing ratio is n, then n rotations of the pulley 10 correspond to one rotation of the pedal 3.

The zero value of the pedal phase angle is determined by the magnet 13 generating a pulse in the Hall element 15. When the pulse indicating this zero value is input to the microcomputer 17, the phase of the pedal becomes 0, and by the time the next pulse indicating the zero value is input, n pulses are generated from the Hall element 16 by the magnet 14. do. By counting this with the microcomputer 17, the phase angle of the pedal can be detected. That is, at the point in time when n1 pulses out of the n pulses that should be input now, the phase angle θ of the pedal is obtained by the value of the following equation.

Various programs are possible for this control signal, but in order to eliminate the dead center of pedal rotation,
The program is such that the rotational load on the pedal is minimized when the pedal reaches the top dead center and bottom dead center, and is maximized when the pedal is at an intermediate angle.

Furthermore, when changing the load on the left and right pedals, the phase angle is shifted by π and a large load and a small load are repeated. In other words, if we increase the load at the place where it is easiest to step when stepping with the right foot, and decrease the load at the place rotated by π from this phase angle (the place where it is easiest to step when stepping with the left foot). , the load on the right foot is greater than the load on the left foot, so it is particularly effective when you want to improve your right foot.
