FIGS. 1 to 5 are diagrams showing an embodiment of the present invention, and FIGS.
FIG. 4 shows a front view, a side view, and a rear view of the same machine.
5 is a block diagram showing an electric configuration of a drive and operation control system of the gyro rotating wheel of the gyro stepping machine according to the embodiment of the present invention, and FIGS. 5A and 5B are mechanical vectors of the gyro rotating wheel. Are respectively shown.

1 to 3, a gyro stepping machine according to the present invention has a handle 1,
The handle 1 has a handle axis Z-Z 'and includes handle rods 2 and 2' extending in the left-right direction with respect to each other. A gyro rotary wheel 4 having a rotation axis YY 'orthogonal to the handle axis ZZ' is attached to a support frame 3 integrated with a lower portion of the handle 1 together with a protective cover 5.

A DC motor 6 and a generator 7 for rotating the gyro rotary wheel 4 on the YY 'axis are mounted on the support frame 3, respectively. The lower end of the support frame 3 is rotated by a rotary shaft 10 and a bearing 11 so that the lower end of the support frame 3 is rotatable with respect to a fixed frame 9 integrated via a rotary shaft 13 to be described later. 10 'and the bearing 11' respectively support. Support stand 8
Is pivotally mounted on a base 12 that is placed on a floor or the like. In this case, the support base 8 is provided with the handle shaft Z-
Z 'and the rotation axis YY' are rotatably mounted on the X-X 'axis perpendicular to the rotation axis. That is, the rotation shafts 13 and 13' and the bearings 14 and 14 'are provided on the support 8 so as to be rotatable. It is supported by.

As clearly shown in FIG. 3, the swing angle α when the support 8 swings with respect to the base 12 is determined by the angle adjusting bolt 1.
5 and 15 ′ are attached to a pair of fastening plates 16, 16 ′ attached to the base 12 by bolts 15 for angle adjustment,
By rotating the handles 17, 17 'respectively integrated with the angle adjustment bolts 15, 1', the angle adjustment bolts 15, 1
The distance "1" between the tips of the 5 'can be appropriately changed and adjusted, and set by restraining the movement of the restraining rod 18 fixed to the rotating shaft 13'.

On both side surfaces of the restraining rod 18, coil springs 19, 1 and 1 connected to the above-mentioned angle adjusting bolts 15 and 15 ', respectively.
9 'is attached, so that the impact when the restraining rod 18 comes into contact with the angle adjusting bolts 15, 15' is reduced. A left foot step 21 and a right foot step 21 'having well-known spring bar dampers 20, 20' are attached to the bottom upper surface of the support stand 8, and both step steps 21, 21 'are provided for the exerciser. By the stepping motion, the support 8
Can be pivoted up and down around a rotation axis yy 'passing through two pivot points spaced on a straight line perpendicular to the rotation axis XX'.

The electrical configuration of the gyro stepping machine according to the present embodiment will be described below with reference to FIG. Note that, in FIG. 4, the dotted line indicates a mechanical connection portion. As shown in FIG. 4, the DC electric motor 6 for driving the gyro rotating wheel 4 uses a power supplied from an AC 100 V via an AC / DC converter 22 to a handle rod 2.
By turning on a power ON / OFF switch 23 attached to the power supply, the rotary drive is performed.

By the rotation of the gyro rotating wheel 4 driven by the DC electric motor 6, a voltage proportional to the number of rotations is generated from the generator 7, and the generated pressure is generated by a potentiometer mounted on the handlebar 2 '. Alternatively, it is fed back to the speed controller 25 of the DC motor 6 via a sliding resistor type speed adjuster 24, and at the same time, a tachometer 26 for displaying the number of revolutions of the gyro rotating wheel 4 attached to the fixed frame 9 and It is supplied to the usage time meter 27. The speed regulator 24
For example, rotates in conjunction with the rotation of the handle rod 2 'around the axis PP' (FIG. 3), and changes the above-mentioned generated voltage by a built-in variable resistor and supplies it to the speed controller 25.

When the stepping exerciser turns on the power ON / OFF switch 23 of the handle bar 2, DC power is supplied to the electric motor 6, the gyro rotating wheel 4 rotates, and the tachometer 26 controls the rotation speed. , The usage time meter 27 displays the usage time. By adjusting the speed adjuster 24 of the handle rod 2 'around the axis PP' of the handle rod 2 ', the rotation speed of the gyro rotary wheel 4 can be appropriately controlled.

It is a matter of course that a configuration using a storage battery instead of the AC 100 V is also possible. In this case, the AC / DC converter 22 becomes unnecessary. Now,
Considering the gyro rotary wheel 4 with reference to FIGS. 5A and 5B, the rotational direction of the gyro rotary wheel 4 is now viewed from one end Y side of the YY ′ axis as shown in FIG. ) To rotate counterclockwise (when changing the direction of rotation, reverse the position of the rotation direction setting switch 28 by the well-known DC motor forward / reverse method in FIG. 4) and rotate at that time. Is ω rad / sec, and the moment of inertia about the rotation axis YY ′ is Igr · cm · sec ² , the angular momentum Hgr · cm · sec of the gyro rotating wheel 4 is expressed by the following equation (1).

H = Iω (1) The magnitude and direction of H are represented by the vector of thick arrows in FIG. The step athlete moves to the left step 2
1 and the weight is applied to the left foot, the support base 8 rotates clockwise about the rotation axis XX ′ as viewed from the X side, and the input torque is applied to the gyro rotating wheel 4 via the fixed frame 9. T
i ₁ gr · cm is applied. Therefore, the angular momentum of the gyroscope rotational shaft 4 by the principle of gyro mechanics 'moves in the direction of, as a result, the handle 1 handle shaft Z-Z' combined vector H of the vector H and the vector Ti ₁ from one end Z side of It will be rotated counterclockwise.

[0019] Then, when put weight on the right foot stepped on the right side of the foot stand 21 ', the orientation of the Ti ₁ becomes a reverse, handle 1 is rotated in a clockwise direction. As described above, the step 21,
If you keep stepping on 21 'alternately, handle 1
Rotates clockwise and counterclockwise alternately,
Acts as a rotational movement on the body via the hand holding the 2 '.

The magnitude of the output torque To ₁ gr.cm around the axis Z-Z 'of the handle 1 is expressed by the following equation (2), where the rocking rotation speed of the support 8 by stepping is Ω rad / sec. It is. To ₁ = H × Ω (2) Therefore, the rotational speed ω of the gyro rotating wheel 4 in the equation (1)
Is changed, the magnitude of To ₁ can be appropriately changed. It can also be changed according to the magnitude of Ω, that is, the magnitude of the stepping speed.

Further, when only the handle 1 is rotated clockwise by operating the handle bars 2 and 2 'viewed from, for example, one end Z side of the ZZ' axis without stepping on the foot, FIG.
As shown in (b), the input torque T is applied to the gyro rotating wheel 4.
i ₂ acts, the angular momentum vector H 'moves to the support base 8 as a result, the rotation axis X-X' H viewed from X side is rotated clockwise, to generate an output torque the To _2. Similarly, when the handle 1 is rotated counterclockwise around the ZZ 'axis, the support base 8 is rotated counterclockwise as viewed from one end X side.

As a result, the footstep 2 is rotated by the clockwise and counterclockwise rotation of the handle 1 about the ZZ 'axis.
The support 8 on which the bases 1 and 21 'are mounted swings around the XX' axis passing through the bearings 14 and 14 'mounted on the base 12. As described above, in addition to the stepping motion, it is possible to generate the turning force of the handle, the swinging power of the support 8 to which the stepping plate is attached, and the combined kinetic force thereof. Rather, it can be used more effectively for strengthening and training a wide range of muscle strength sites in the body of the exerciser.

It is logical that the DC motor 6 can be used as a conventional stepping machine by setting the rotation speed of the DC motor 6 to zero and setting the distance "l" between the tips of the angle adjusting bolts 15 and 15 'to zero. Needless to say, by further constructing a structure in which the position of the handle 1 on the ZZ 'axis with respect to the gyro rotating wheel 4 can be fixed by being shifted by 90 °, the exerciser can move the steering wheel 1 on the side surface of the gyro rotating wheel 4, that is, An input torque can be applied to the gyro rotating wheel 4 by standing and standing on the position of Y or Y 'on the YY' axis and swinging the handle 1 around the XX 'axis. According to the principle of the above, the output torque around the ZZ 'axis is
It is also possible to apply a rotational movement to the body through the hand holding the 2 '.

In the above description, the embodiment of the gyro stepping machine according to the present invention has been described. Instead of the stepping machine of the stepping machine, a well-known pedal for a cycle machine (aero bike) and a saddle are provided to shift the weight to the left and right. It is needless to say that the present invention can be applied to a gyrocycle machine that obtains the same operation and effect as the gyrostepping machine by pedaling while pedaling.

As is apparent from the above description, according to the present invention, while using a conventional stepping machine as a base,
Ability to exercise and strengthen muscles over a wide range of muscle parts of the body of the exerciser can be imparted, and various exercise forces can be applied in a complex manner in accordance with the exerciser's intention, thereby providing playability. Therefore, the effect of inducing the repetitive training movement can be further contributed to the improvement of the training effect.

In addition, since the added mechanical structure and electrical configuration are not complicated, the cost increases as much as possible.
It can be suppressed.
