[0001]
BACKGROUND OF THE INVENTION
The present invention utilizes the gyro effect of a high-speed rotating wheel in addition to the stepping motion of the stepping machine, and when the stepping exerciser performs the stepping motion, the steering wheel of the machine is repeatedly rotated clockwise or counterclockwise or The present invention relates to a gyro stepping machine that effectively achieves exercise or enhancement of muscle strength in a wide range of the body by generating a peristaltic motion on a footrest or generating a combined motion of both motions and acting on the body.
[0002]
[Prior art]
Conventionally, a so-called well-known stepping machine, which is used for training and strengthening the strength of the body (especially the leg), a pair of stepping machines on a fixed base, and by only moving the legs up and down, The one for the purpose of strengthening is used. There are also stepping machines equipped with a handle fixed to a fixed base. In this case, the handle is used only to support the hand or to extend and contract the lateral abdominal muscle (exterior oblique muscle) at best. It is.
[0003]
However, in the conventional stepping machine, it has been impossible to apply a rotational motion and left / right peristaltic motion to the body by a stepping motion to increase the strength of a wide range of the body.
[0004]
[Problems to be solved by the invention]
In view of such prior art, the object of the present invention is to enable an exerciser to effectively increase not only leg muscle strength but also muscle strength in a wide range of the body simultaneously by stepping exercise. By applying the gyro effect to generate various movements, these movements are applied to various parts of the athlete's body to provide a stepping machine that can achieve strength enhancement or training.

Furthermore, by attaching a support base for supporting the footrest so as to be rotatable about one axis with respect to the base, an input torque is applied to the gyro rotating wheel due to weight movement caused by the footstep exercise of the athlete. It is arranged so that it can.
Due to the input torque, the gyro rotating wheel generates a precession output torque around the handle shaft, and the precession output torque causes the steering wheel to perform repeated clockwise and counterclockwise rotational movements in conjunction with the stepping motion. In addition, a rotational force can be applied to the body through the hand holding the handle according to this rotational movement.
[0007]
Further, when the handle is intentionally rotated manually, an input torque is applied to the gyro rotating wheel by the rotational force, and the gyro rotating wheel has a support base that supports the footrest around one axis with respect to the base. Therefore, it generates a peristaltic output torque around the above-mentioned axis relative to the base of the support base. The structure which can give the inclination rotational force to is provided. Furthermore, it goes without saying that each of the above-described exercises can be simultaneously generated in a complex manner and act on an exerciser.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the gyro stepping machine according to the present invention will be described in more detail based on an embodiment shown in the accompanying drawings.
FIGS. 1 to 5 are views showing embodiments of the present invention. FIGS. 1, 2 and 3 are a front view, a side view and a rear view of the same machine, and FIG. 5 is a block diagram showing the electrical configuration of the drive and operation control system of the gyro rotating wheel of the gyro stepping machine according to the embodiment, and FIGS. 5A and 5B are explanatory diagrams showing the mechanical vector of the gyro rotating wheel. Respectively.
[0010]
1 to 3, the gyro stepping machine according to the present invention includes a handle 1, and the handle 1 has a handle shaft ZZ 'and extends in the left-right direction with respect to each other. And 2 '. A gyro rotating 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.
[0011]
A DC electric motor 6 and a generator 7 for rotating the gyro rotating wheel 4 on the YY ′ axis are attached to the support frame 3.
The lower end portion of the support frame 3 is rotated by a rotary shaft 10 and a bearing 11 so that the lower end portion of the support frame 3 is rotatable with respect to a fixed frame 9 integrated via a support base 8 and a rotary shaft 13 described later, and the upper end portion is a rotary shaft. 10 'and bearing 11' are supported respectively. The support base 8 is pivotally attached to a base 12 that is stationary on the floor or the like. In this case, the support base 8 has the handle axis ZZ ′ and the rotation axis YY ′ described above. They are rotatably attached to the XX ′ axes perpendicular to each other, that is, are rotatably supported by front and rear rotary shafts 13, 13 ′ and bearings 14, 14 ′ provided on the support base 8.
[0012]
As clearly shown in FIG. 3, the swing angle α when the support base 8 swings with respect to the base 12 is a pair of fastening plates on which the angle adjusting bolts 15 and 15 ′ are attached to the base 12. The distance between the tip ends of the angle adjusting bolts 15 and 15 'by rotating the handles 17 and 17' respectively integrated with the angle adjusting bolts 15 and 15 'with respect to 16 and 16'. It can be set by changing and adjusting “l” as appropriate to restrain the movement of the restraining rod 18 fixed to the rotating shaft 13 ′.
[0013]
Coil springs 19 and 19 'respectively connected to the angle adjusting bolts 15 and 15' are attached to both side surfaces of the restraining rod 18, and when the restraining rod 18 comes into contact with the angle adjusting bolts 15 and 15 '. The impact is reduced. A left foot step 21 and a right foot step 21 'having well-known spring bar dampers 20 and 20' are attached to the upper surface of the bottom of the support base 8, and these foot steps 21 and 21 'are attached to the athlete. By the stepping motion, it can be pivoted up and down around the rotational axis yy ′ passing through two pivot points separated on a straight line perpendicular to the rotational axis XX ′ of the support base 8 It has become.
[0014]
Now, the electrical configuration of the gyro stepping machine according to the present embodiment will be described with reference to FIG. In FIG. 4, a dotted line indicates a mechanical coupling portion.
As shown in FIG. 4, the DC electric motor 6 for driving the gyro rotating wheel 4 includes a power ON / OFF switch 23 attached to the handle bar 2 with power supplied from the AC 100V via the AC / DC converter 22. It is rotationally driven by turning it on.
[0015]
Due to the rotation of the gyro rotating wheel 4 driven by the DC electric motor 6, a voltage proportional to the rotational speed is generated from the generator 7, and the generated pressure is generated by a potentiometer or a slide attached to the handle 2 '. A tachometer 26 for displaying the number of revolutions of the gyro rotating wheel 4 and an operating time meter which are fed back to the speed controller 25 of the DC motor 6 through the resistor type speed regulator 24 and are attached to the fixed frame 9 at the same time. 27. The speed adjuster 24 rotates in conjunction with, for example, the rotation of the handle bar 2 'around the axis PP' (FIG. 3), and the generated voltage is changed by a built-in variable resistor. To supply.
[0016]
When the stepping exerciser turns on the power ON / OFF switch 23 of the handle bar 2, the DC power is supplied to the electric motor 6, the gyro rotating wheel 4 rotates, the tachometer 26 determines the rotation speed, and the usage time. A total of 27 displays the usage time.
By adjusting the speed adjuster 24 of the handle 桿 2 ′ by adjusting the rotation of the handle 桿 2 ′ around the axis PP ′, the rotation speed of the gyro rotating wheel 4 can be appropriately controlled.
[0017]
Of course, it is also possible to use a storage battery instead of the AC 100V. In this case, the AC / DC converter 22 is unnecessary.
Now, considering the gyro rotating wheel 4 with reference to FIGS. 5 (a) and 5 (b), the rotational direction of the gyro rotating wheel 4 is now as viewed from one end Y side of the Y-Y 'axis. As shown by the arrow in (a), rotate counterclockwise (when changing the rotation direction, reverse the position of the rotation direction setting switch 28 based on the well-known DC motor forward / reverse rotation method in FIG. 4) Assuming that the rotation speed is ω rad / sec and the moment of inertia with respect to the rotation axis YY ′ is Igr · cm · sec ² , the angular momentum Hgr · cm · sec of the gyro rotating wheel 4 is expressed by equation (1).
[0018]
H = Iω (1)
The magnitude and direction of H are represented by a vector of arrows with thick lines in FIG.
When the stepping exerciser steps on the left footrest 21 and puts his / her weight on the left foot, the support base 8 rotates clockwise with respect to the rotation axis XX ′ axis as viewed from the X side, and the fixed frame 9 is moved. Through this, an input torque Ti ₁ gr · cm is applied to the gyro rotating wheel 4. Therefore, according to the principle of gyrodynamics, the angular momentum of the gyro rotating shaft 4 moves in the direction of the combined vector H ′ of the vector H and the vector Ti _1, and as a result, the handle 1 is moved from one end Z side of the handle shaft ZZ ′. It will rotate counterclockwise.
[0019]
Next, when applied to the right foot weight stepping the right foot base 21 ', the orientation of the Ti ₁ becomes reversed, the handle 1 is rotated in a clockwise direction.
As described above, when the footrests 21 and 21 'are alternately stepped on, the handle 1 rotates in the clockwise and counterclockwise directions accordingly, and the body 1 can be applied to the body through the hand holding the handle rods 2 and 2'. Acts as a rotational motion.
[0020]
The magnitude of the output torque To ₁ gr · cm around the axis ZZ ′ of the handle 1 is expressed by the following equation (2) when the peristaltic rotation speed of the support base 8 by stepping is Ω rad / sec.
To ₁ = H × Ω (2)
Therefore, the magnitude of To ₁ can be appropriately changed by changing the rotational speed ω of the gyro rotating wheel 4 in the equation (1). It can also be changed by the size of Ω, that is, the stepping speed.
[0021]
Furthermore, when only the handle 1 is rotated in the clockwise direction by operating the handle rods 2 and 2 'when viewed from one end Z side of the Z-Z' axis without stepping on, as shown in FIG. 5 (b). The input torque Ti ₂ acts on the gyro rotating wheel 4 and the angular momentum vector H moves to H ′. As a result, the support base 8 is rotated clockwise as viewed from the X side of the rotation axis XX ′, and output Torque To ₂ is generated. 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.
[0022]
As a result, the support base 8 to which the footrests 21 and 21 'are attached by the rotation of the handle 1 around the ZZ' axis in the clockwise and counterclockwise directions passes through the bearings 14 and 14 'attached to the base 12. Will swing around the XX 'axis.
As described above, in addition to the stepping motion, it is possible to generate the rotational force of the handle, the repulsive force of the support base 8 to which the footrest is attached, and the combined motion force thereof. Rather, it can be used effectively for strengthening and training a wide range of muscle strength sites in the body of the exerciser.
[0023]
Needless to say, it can be logically used as a conventional stepping machine by setting the rotational speed of the DC motor 6 to zero and setting the distance “l” between the tip ends of the angle adjusting bolts 15 and 15 ′ to zero. Furthermore, the 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 ° makes it possible for the athlete to move the side surface of the gyro rotating wheel 4, that is, YY. The input torque can be given to the gyro rotating wheel 4 by standing on the position of Y 'or Y' on the 'axis and swinging the handle 1 around the XX' axis. The rotational torque around the Z-Z ′ axis can be applied to the body through the hand holding the handlebars 2 and 2 ′.
[0024]
In the above, the embodiment of the gyro stepping machine according to the present invention has been described, but instead of the stepping machine stepping platform, a well-known cycle machine (aero bike) pedal and saddle are provided, and the weight is moved to the left and right. Of course, the present invention can also be applied to a gyro cycle machine that obtains the same effect as that of a gyro stepping machine by pedaling.
[0025]
As is clear from the above description, according to the present invention, it is possible to impart training and strength enhancing effects to muscle parts over a wide range of an exerciser's body, based on a conventional stepping machine. Since various exercise forces can be combined and act according to the intentions of the athlete, it can be playful, and it also has the effect of inducing repeated exercise exercises, which contributes to the improvement of the exercise effect more and more. It becomes possible.
[0026]
Moreover, since the added mechanical structure and electrical configuration are not complicated, an increase in cost can be suppressed as much as possible.
