Description of the Related Art In recent years, health management, weight control, fitness training, etc. have attracted attention, and various training devices for these purposes have been developed and commercialized. One of these machines is called a pedal machine, which has the same basic structure as a cycling bicycle. That is,
This pedal machine allows a person to put their foot on the pedal and
By pedaling the pedal, a rotating plate (equivalent to a bicycle wheel) connected to the pedal is rotated. At this time, by applying a predetermined load to the rotating plate, a load is applied to the pedaling action and exercise.

構がある。[0003] As means for applying the load, there are methods using friction, wind pressure, and the like. The former method involves, for example, wrapping a belt-shaped band around the peripheral side of the rotating plate and tightening the band against the rotating plate.
There are mechanisms that generate a predetermined frictional force between a band and a rotary plate, and mechanisms that press a stopper member against the side surface of a rotary plate, such as in an automobile disc brake. As for the latter, for example, there is a mechanism in which a large number of blades are attached to a rotary plate and utilizes the air resistance that the blades receive when the rotary plate rotates.

荷がいきなり足に加わることにより、筋肉を痛めるおそ
れがある。さらに、バンド等を回転板に対して締め付け
る機構が複雑となる。However, the conventional pedal machine described above has the following problems. In other words, in the former case, since friction is used, frictional heat is generated and loss occurs, and the band and stopper members wear out after long-term use, which not only causes problems in maintenance and parts replacement. There is a problem in that the frictional force (contact resistance) generated between the rotary plate and the band etc. decreases due to wear, making it impossible to obtain a desired load. Furthermore, since a constant load is always applied regardless of the state of exercise (rotation speed), a large load is suddenly applied to the legs at the beginning of rowing, which may cause muscle damage. Furthermore, the mechanism for tightening the band and the like against the rotary plate becomes complicated.

ることにある。On the other hand, in the case of the wind pressure type, the load is approximately proportional to the rotational speed, so a large load is not applied to the muscles at the beginning of the exercise, but it is not only difficult to change and adjust the load. In order to obtain a large load, a large rotary plate is required, and it is not suitable for miniaturization.In the end, it is used in combination with the above-mentioned friction type, and the final product also has the above-mentioned problems. The present invention has been made in view of the above-mentioned background, and its purpose is to create a small, simple structure, which can be used stably for a long period of time, and which requires a relatively small load at the beginning of exercise. Our goal is to provide a pedal machine that is unique.

A pedal machine is equipped with a load generating means that applies a predetermined load to the yoke, and the load generating means includes a magnetic circuit configured by placing magnets on one or both of the opposing surfaces of the yoke, and The magnetic damper device comprises a magnetic damper device having a conductor that moves relatively in a direction to cut the magnetic flux, and one of the magnetic circuit or the conductor is attached to the rotating body.

。[Function] In the pedal machine with the above configuration, when the pedal is pedaled, the rotor rotates, and the conductor and magnetic circuit move relative to each other. At this time, an eddy current flows in the conductor due to electromagnetic induction. The eddy current and the magnetic flux of the magnetic circuit generate a braking force on the rotating body in the opposite direction to the rotating direction, which is transmitted to the pedal side as a load. In this device, a load can be generated in a non-contact state, so there is no loss due to heat generation, etc., and since there is no mechanical contact between the parts, there is no risk of damage. In addition, the magnitude of the braking force generated is proportional to the relative movement speed between the magnet and the conductor, that is, the rotation speed of the rotating body, so the load is small at the beginning of the movement at a slow rotation speed, and as the rotation speed increases. The load also gradually increases.

, 36 (S poles) are arranged facing each other, and a magnetic circuit is formed between the respective permanent magnets 30, 32, 34, and 36 on the opposing surfaces by a bidirectional magnetic field directed from the N pole to the S pole as shown by the arrow in the figure. ing.

In addition, a state in which the boundary lines 36 and 38 are located in a direction perpendicular to the rotation direction of the rotary plate 22 (for convenience, this state is referred to as "0")
When the rotating plate 22 is rotated at a constant speed in the direction of the arrow when the rotating plate 22 is at a position of In order to cut, electromotive forces E1 and E2 are induced to the rotating plate 22 according to Fleming's right-hand rule, and as a result, on the conductive plate 22,
Three eddy currents flow as shown.

い。At this time, the eddy current generates a braking force on the rotary plate 22 in the direction opposite to the direction of the arrow due to the action of the magnetic field, thereby applying a load to the pedaling movement connected to the rotary plate 22. However, in this embodiment, the eddy current ia shown by the solid line in the center mainly flows, and the eddy current ib directed to the outside shown by the dashed lines on the left and right does not flow as much as the eddy current ia.

われることになるのである。[0015] This is the electromotive force E that is opposite to each other next to each other.
1, E2 occurs, the adjacent permanent magnets 30, 32
In addition, the eddy current shown by the solid line between 34 and 36 flows more easily, and does not flow on the left and right sides accordingly. Therefore, the eddy current in the gap d with high magnetic flux density has a large electromotive force, and the path through which it flows becomes shorter, so that more of the current is effectively used for braking force.

Because it is proportional to the rotational speed of the rotary plate 22, the braking force that occurs when the rotation speed is low at the beginning of the exercise, that is, the load applied to the feet, is small, and when the rotation speed is high, a large load is applied according to the rotation speed. Not only is there no risk of injuring the muscles at the beginning, but the load is generated in accordance with the amount of exercise (rotational speed), so it is possible to generate an appropriate load in accordance with the user's muscle strength and usage conditions.

As shown in B), both permanent magnets 30, 32 and 34,
36 is located at a predetermined angle (20 degrees) with respect to the rotating direction of the rotary plate 22. In this state, when the rotary plate 22 rotates in the direction of the arrow, the electromotive force E1 based on each permanent magnet 30, 32, 34, 36,
E2 is generated on the rotary plate 22, and eddy currents ia' and ib' are also generated in a direction perpendicular to both the direction of the magnetic field and the direction of rotation of the rotary plate 22, as shown in the figure.

荷も小さくなる。By the way, when looking at the entire high magnetic flux density region formed by the permanent magnets, the area near the boundary line of the permanent magnets N
Then, the direction of the electromotive force becomes opposite and cancels out. Therefore, in reality, an electromotive force is generated only in the portions other than the above-mentioned N, and based on this, an eddy current flows as shown by the arrow in the figure. Therefore, in this state, the above figure (A)
Since the induced electromotive force is smaller and the eddy current is smaller than in the case shown in , the resulting braking force, that is, the load is also smaller.

Both electromotive forces E1 and E2 generated in the above direction are completely opposite to each other and cancel each other out. Therefore, as shown in the figure, the eddy current IC only flows in a small amount at both ends of the high magnetic flux density region, and almost no braking force or load is generated.

That is, by rotating the permanent magnets 30, 32, 34, and 36, the relative angular positional relationship between the boundary line of the permanent magnets and the rotating direction of the rotary plate 22 can be changed from the state shown in FIG. By changing it, arbitrary braking force and load can be obtained, and the load can be adjusted more appropriately according to the muscle strength of the user.

In addition, if there is no need to adjust the load, 1
The braking force may also be varied by having only one magnetic pole present, or by making the magnet having only one magnetic pole replaceable and installing magnets with different magnetic forces. Further, in the above-described embodiments, an example in which one load generator is provided has been described, but the present invention is not limited to this, and it goes without saying that a plurality of load generators may be provided.

It consists of a magnetic damper device that has a conductor that moves relatively in the cutting direction, and because one of the magnetic circuit or the conductor is attached to the rotating body, it is possible to generate a load in a non-contact state, thereby reducing losses due to heat generation etc. There is no mechanical contact between the parts, so there is no risk of damage and no maintenance is required. Furthermore, since the magnitude of the load is determined according to the rotational speed of the rotating body, the load is small at the beginning of the exercise when the rotational speed is slow, and therefore the muscles will not be damaged by suddenly applying a large load. Furthermore, the structure can be simple, consisting of a magnet and a conductor, and the size can be reduced.
