[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a torque addition type weight device capable of generating a torque that causes a torsional force to be generated in the weight by utilizing the gyro effect of a rotor in addition to the weight of the weight. Such a torque addition type weight device is typically used for exercise of muscles of healthy persons and recovery of motor function of persons with motor dysfunction, and further for centrifugal force due to rotational movement of body in weightlessness of outer space. By adding and generating a twisting force, it is possible to effectively utilize for the purpose of preventing a decrease in muscle strength.

[0002]

2. Description of the Related Art Conventionally, exercise weights such as dumbbell exercise weights have been used by applying weight and centrifugal force to muscles, but a single acting force mainly determined by the weight is given to a gymnast. Therefore, it has been impossible to generate and act a synergistic twisting force by simple and inexpensive means.

[0003]

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, an object of the present invention is to provide a weight with a rotor mechanism that rotates at high speed, and apply an input torque to the rotor by sports motion or the like. (EN) A torque addition type weight device capable of generating a torsion torque in a weight by a gyro effect of a rotor and adding a torque to the weight weight to exert a torsion force to increase the weight effect by two acting forces. It is a thing.

[0004]

In view of the above-mentioned object of the invention, according to the present invention, the torque weight structure is provided with a rotor which is rotationally driven at a high speed, and is perpendicular to the rotation axis of the rotor. By applying an input torque around the input shaft, the rotor generates a precession output torque due to the gyro effect, and a structure capable of detecting a twisting force generated from the precession output torque is provided. . That is, this precession output torque is generated around the precession axis that is perpendicular to the rotor shaft of the rotor and the input shaft, becomes the torsional force of the weight, and can be sensed synergistically with the weight of the weight. The weight effect can be enhanced.

That is, according to the present invention, in the torque addition type weight device provided with the rotor mechanism having at least one rotor which is rotationally driven by the high-speed rotation drive means, the rotor is rotated at high speed. By the input torque imparted by the input rotary motion around the input shaft perpendicular to the shaft, the precession output torque by the gyro effect is generated around the precession shaft perpendicular to both the high-speed rotating shaft and the input shaft, To solve the above-mentioned problems, a torque addition type weight device is constructed which is capable of simultaneously detecting the weight of the weight including the rotor mechanism and the twisting force due to the differential output torque.

According to this structure, for example, the positions of the torque input shaft and the precession output torque shaft can be arbitrarily set according to the condition and type of sports exercise, and further, the position can be electrically or mechanically driven. The magnitude of the precession output torque can be arbitrarily set by arbitrarily setting the high rotation speed of the driven rotor.

[0007]

According to the above-mentioned structure, a torsional force can be generated in the weight by the precession output torque generated according to the input of the torque to the rotor that rotates at a high speed, and the weight of the weight and the torsional force are combined. Since the effect can be obtained, the two effect forces, which are superior to the conventional weight effect due to the single weight effect, can be exerted and sensed on the muscles and the like of the gymnast, so that the weight effect can be enhanced.

It is a top view showing the stored state.

With reference to FIGS. 1 to 3, a torque addition type weight device according to the present invention includes a rotor mechanism, and the rotor mechanism has a rotor 1. The rotor 1 has a cylindrical rim, has an appropriate moment of inertia about the axis, and makes the axis S-S 'coincide with the rotation axis 3 of the electric motor 2 so as to be bonded or screwed appropriately. Fixed by means, the electric motor 2 is fixed to the support frame 4. This support frame 4
Is fixed to one inner wall of the outermost case 5. When an outer rotor type electric motor is used as the electric motor 2, the inner stator portion of the electric motor is directly fixed to the case 5 and the outer rotor portion is fixed to the inner surface of the cylinder of the rotor 1. It becomes possible to omit the support frame 4.

Inside the case 5, a suitable number of power source dry cells, that is, four dry cells 6, 7, 8 and 9 in this example are housed, and they can be operated by projecting to the outside of the case 5. The power source opening / closing switch 10, the variable resistor 11 for adjusting the speed of the electric motor 2 mounted outside the case 5,
The electric power of the four dry batteries 6, 7, 8 and 9 is connected to the electric motor 2 through the electric wiring in the case 5 and the metal piece (not shown) for battery series connection provided inside the bottom lid 12. It has become. Here, FIG. 4 is a circuit diagram showing a drive power supply system of the electric motor 2.

The four batteries 6 to 9 are put in and taken out from the case 5 by opening and closing the bottom cover 12. The bottom cover 12 is fixed to the case 5 by attaching fixing screws (not shown) such as screw holes 13-1 to 13-4 of fixing screws as shown in FIG. As shown in the figure, the case 5 has a hollow prismatic (cylinder-shaped) box structure as a housing portion of the rotor mechanism, the bottom portion is closed by the above-mentioned bottom lid 12, and the outer portion has an outer shape. It has a circular flange portion 5a, and at this flange portion 5a, it is connected and attached to the hand holder 14 via the connecting rotary shaft 13. The connecting rotary shaft 13 has upper and lower holding plates and at the same time has a coupling screw (not shown) inside.
It can be formed from a component, and the flange portion 5a of the case 5 and the lower bottom plate 14a of the handle holder 14 are sandwiched between the upper and lower pressing plates by fastening the internal coupling screw.

Here, the hand holder 14 has a grip portion 14b.
By having a finger on the grip portion 14b, the entire weight device can be gripped. The mutual directional relationship between the grip axis XX ′ of the handle holder 14 and the axis of the rotor 1 and the rotation axis SS ′ is determined by the orientation of the handle holder 14 when connected to the case 5 as the connection rotation axis. 13 is set to rotate around the angle setting knob 15, and _{one of the} through conical holes h ₁ to h ₄ arranged on the circumference of the diameter D in the flange portion 5a of the case 5 and the lower bottom plate 14a of the handle holder 14 is set. Can be determined by the fitting. That is, the angle setting knob 15 is lifted up against the spring spring mechanism 16, the hand holder 14 is rotated with respect to the case 5 via the connecting rotary shaft 13, and the conical tip end 17 of the angle setting knob 15 is fitted to h ₂ . When combined, the rotation axis S-S 'of the rotor 1 and the grip axis X of the hand holder 14
As is clear from FIG. 3 from the parallel relationship shown in FIG. 1, −X ′ is set in a posture relationship having a crossing angle of 90 °.

In other words, by engaging the conical holes h ₃ and h ₄ by the same operation of the angle setting knob 15, the opposing angular postures of the grip axis XX ′ and the rotation axis SS ′ are intentionally changed. It is possible. Although only _four conical holes h ₁ to h ₄ are shown in FIG. 1, it is of course possible to provide five or more same-shaped holes on the diameter D shown in FIG. 3 if necessary. Is.

The weight device having the above-described structure is added to the total weight of the weight of the rotor mechanism housed in the case 5 and the weight obtained by forming the hand holder 14 with a large specific gravity material such as iron material. The torque is generated by the gyro effect exerted by the rotor 1 rotating at a higher speed to generate a twisting force to increase the weight effect. Next, the grip shaft XX ′ and the rotary shaft S are rotated. The twisting force generated from the relationship between the angle with −S ′ and the input torque and precession output torque to the rotor 1 will be described with reference to FIG.

[0015] Now, the rotor 1 is rotated at a high speed by receiving the rotational driving force of the electric motor 2 in a clockwise 'about the S _1' rotation axis S-S when viewed from the side, the magnitude of the angular momentum of the time Let H be H. For example, when a gymnast grips the grip portion 14b of the hand holder 14 and a rotational motion about the YY 'axis due to dumbbell exercises is applied counterclockwise when viewed from the Y'side of the YY' axis, the rotation occurs. The input torque T _i is Y ′ in the child 1.
It is added counterclockwise when viewed from the side.

At this time, the rotation axis S-S 'of the rotor 1 moves in the direction of the combined vector H'of the input torque T _i vector and the angular momentum vector H of the rotor 1 by the physical action, that is, the gyro effect ( Precession motion torque) is generated, and as a result, a precession output torque that exerts a twisting force counterclockwise around the Z-Z 'axis when viewed from the Z'side is generated.

Similarly, it is possible to generate different torsional forces in various directions by combining the positional relationship between the S-S 'axis, the XX' axis and the input torque and the vector direction. Also, the high speed value of the rotor 1 is set to the variable resistor 1
By adjusting the knob 18 of the electric motor 2
The output torque of the precession can be adjusted by adjusting the rotation speed of the.

The rotary shaft 23, which rotates at high speed, is supported at its both ends by support plates 26 and 27 via ball bearings 24 and 25.

The support plates 26 and 27 are the bottom plate 2 of the case 28.
It is fixed to 8a and the top plate 28b on the upper side by screwing or the like. The mainspring of the mainspring gear mechanism 20 stores the rotational driving force by rotating the winding knob 29 to rotationally drive the output gear 21, while the rotation start and stop of the output gear 21 are performed by a known release knob. It can be controlled by operating 30.

The rotation speed of the rotor 19 is adjusted by rotating the rotation plate 32 of the governor 31, which is composed of a well-known centrifugal weight fixed on the extension of the high-speed rotation shaft 23 and an elastic support arm, while rotating. The rotational speed of the contact plate 35 is achieved by adjusting and acting the braking force by the contact pressure of the contact plate 35, and the screw engraved at the tip of the adjusting rotary shaft 34 to which the contact plate 35 is attached and the support plate 2

If fitted, unnecessary free rotation of the lever 33 can be suppressed and speed can be set. In the above-described first and second embodiments, when it is desired to increase the total weight of the weight, one or a plurality of ring-shaped weights W ₁ are appropriately provided in the outer peripheral area of the hand holder 14 as shown in FIG. The ring-shaped weight W ₁ may be added or attached to the part, and the ring-shaped weight W ₁ may be attached to the through hole formed in the flange portion of the hand holder 14 and the case 5 or 28 by using known bolts and nuts. can do. That is, the weight W ₁

Next, FIG. 8 is a diagram showing a third embodiment of the torque addition type weight device according to the present invention, which is applied to a dumbbell gymnastics array having two electric motors as a rotation driving means. It is an example of a torque addition type weight device. The torque addition type weight device of the present embodiment includes rotors 41 and 41 ′.
Two cylindrical cases 37 and 37 'each having a pair of rotor mechanisms having
Electric motors 38 and 3 forming a rotary drive source inside the
8'is fixed to the inner wall surfaces of the cylindrical cases 37 and 37 'via supporting frames 39 and 39', respectively, by using fixing means such as bolts and screws. In addition, the above-mentioned first
As described in the above embodiment, when an outer rotor type electric motor is used as the electric motor, the support frame 39,
It goes without saying that it is possible to omit 39 '.

By the way, the two cylindrical cases 37 and 37 'described above are formed in a conventionally well-known array structure by interposing a tube 42, which will be described later, substantially coaxially. In the present embodiment, the cylinder 42 is formed as an integral part with the one cylindrical case 37. 2 mentioned above
The rotating shafts 40 and 40 ′ of the electric motors 38 and 38 ′ housed inside the two cylindrical cases 37 and 37 ′ are arranged substantially coaxially and outwardly, respectively. Respectively have rotors 40 and 41 'fixed as shown. That is, the rotating shafts 40 and 40 'are located on the central axis XX' of the weight device.
It is provided so as to generate rotation in the same direction so as to generate angular momentum vectors in the same direction. Therefore, the electric motors 38 and 38 'are driven so that the two rotary shafts 40 and 40' are both rotating in the clockwise direction or the counterclockwise direction when viewed from one end side of the central axis XX '. Power is supplied.

Here, the above-mentioned cylinder 42 arranged between both cylindrical cases 37 and 37 'is a portion used as a grip, and inside this, it serves as a drive power source for the electric motors 38 and 38'. The dry batteries 43 to 46 are accommodated in a serial arrangement, and a battery electrode plate 47 and a drive power ON / OFF switch 48 are provided at a connecting portion between the cylindrical case 37 and the cylinder 42.

The other case 37 'is attached with the other electrode plate 49, and the case 37' has a grip tube 4 '.
It is adapted to be fastened to the screw 2 by screw engagement. Then, when the case 37 'and the grip tube 42 are screwed together, if the screw fastening does not proceed to the specified position, the drive power supply circuit via the electrode plate 49 is not closed. With this structure, the case 37 'due to incomplete fastening is formed.
It functions as a warning for falling out of the cylinder 42. Further, a spring washer 51 for loosening the fastening at the above-mentioned screw coupling portion is inserted.

Mounting the dry batteries 43 to 46 on the twisting cylinder 42,
The removal is performed by releasing the fastening of the case 37 'from the tube 42. The rotation speed of each rotor 41, 41 'in the rotor mechanism is adjusted by the series circuit of the dry batteries 43-46 and the electric motors 38, 38', as in the case of the drive power supply circuit shown in FIG. The inserted electrically variable resistor 50 is arranged at an appropriate corner of the cylindrical case 37 as shown in the figure, and the electrical resistance value is adjusted from the outside.

Positive and negative electric currents are supplied to the respective motors 38 and 38 'through the electrode plates 47 and 49 for electrical connection to the electric motors 38 and 38'. It goes without saying that it is performed through the electric wiring path (not shown). In FIG. 8, three orthogonal axis systems XX ′ axis, Y intersecting with each other at a substantially intermediate position of the cylinder 42.
With respect to the dumbbell gymnastics rotation motion around the ZZ 'axis in the -Y' axis and the ZZ 'axis, Y is caused by the gyro effect.
The twisting force due to the differential output torque around the -Y 'axis and the twisting force around the ZZ' axis can be generated for the rotational movement around the YY 'axis.

The directions of the rotor axes of the two rotors 41, 41 'housed in the two cylindrical cases 37, 37' are
Change to a structure perpendicular to the XX 'axis, and use the rotor 4
By driving so that the rotation directions of 1, 41 ′ are the same when viewed from the Z or Z ′ side of the ZZ ′ axis,
A torsional force about the YY 'axis is generated for rotational movement about the XX' axis, and a torsional force about the XX 'axis is generated for rotational movement about the YY' axis. It is also possible to provide an array in the form of an array.

Further, in the embodiment of FIG. 8 described above, the case where the rotors 41 and 41 'are formed to have the same rotation direction has been described. However, both rotors 41 provided at both ends of the twisted cylinder 42, If the rotation axis direction of the high-speed rotation of 41 'is set to be a different direction, a combined precession output torque is generated in the entire weight device, and a weight feeling different from that of the above-described embodiment is given to the gymnast. You can

Further, in the third embodiment, if it is desired to further increase the weight of the weight, a plurality of medium split ring-shaped weights W ₂ as shown in FIG. 37 'or both of them, and the weight W ₂ is fixed to the cylindrical cases 37 and 37' by fastening means. The various embodiments of the present invention have been described above.
As a power source for the electric rotation driving means, it is of course possible to use a structure in which an external power source is connected by a conductive wire and used instead of housing the dry battery. In this case, it is needless to say that a structure using only an external power source may be used, or a structure using a dry battery may be used in combination, and instead of the dry battery, an equivalent heavy object may be inserted and used.

As described above, as shown in the application example of the present invention to the dumbbell gymnastics array, the muscle weight training and the recovery training of the motor function can be performed more effectively by the synergistic action of the weight of the weight and the twisting force.
