First Embodiment
An exercise apparatus 1 and an exercise apparatus set 100 according to a first embodiment of the present invention will be described below with reference to FIGS. 1 to 3.
FIG. 1 is a side view of the exercise apparatus 1. Moreover, FIG. 2 is a top view of the exercise equipment set 100 provided with the exercise equipment 1 as a pair, and FIG. 3 is a front view of the exercise equipment set 100. In addition, FIG. 1 becomes L arrow in FIG. 2 and FIG.
Moreover, in this description, the directions of the longitudinal direction X, the lateral direction Y, and the vertical direction Z coincide with the directions for the user P who uses the exercise apparatus 1. Moreover, in each figure, it is referred to as the front A and the back B.

  As shown in FIG. 1, the exercise device 1 has a housing 10, an arm 20 extending in one direction from the housing 10, and a turn for rotatably supporting the arm 20 with respect to the housing 10. And a moving shaft 30.

The housing 10 includes a body frame 11 having a rectangular shape in a side view, a body cover 12 that covers the frame from both sides in the left-right direction Y, and a base frame 13 for supporting the body frame 11. The body frame 11 has a rectangular shape in which two sides extend in the front-rear direction X and the remaining two sides extend in the up-down direction Z in a side view.

A pair of vertical frames 11A in the main body frame 11 extends downward from the lower horizontal frame 11B. The lower end portion of the vertical frame 11A is connected to the upper surface of the base frame 13.

As shown in FIG. 2, the base frame 13 has a frame shape in which two sides extend in the front-rear direction X in top view and the remaining two sides extend in the left-right direction Y.
A pair of left and right frames 13B extending in the left-right direction Y is fixed to the upper surface of the pair of front and rear frames 13A extending in the front-rear direction X. The lower end portion of the vertical frame 11A in the main body frame 11 is connected to the upper surfaces of the left and right frames 13B.
Here, the position in the left-right direction Y at which the body frame 11 is fixed with respect to the left and right frames 13B is a mode of use, that is, an arrangement interval of the exercise devices 1 and a physical size of the user P using the exercise devices 1 Depending, it is possible to change arbitrarily.

An aluminum frame is adopted as each frame member which constitutes each of the main body frame 11 and the base frame 13. Thereby, while suppressing the weight of the whole exercise apparatus 1, an assembly operation can be easily performed by suppressing the weight of each part. The material of each frame member is not limited to aluminum, and can be arbitrarily changed.
A steel plate having a thickness of 1 mm or less is adopted for the main body cover 12. The material of the main body cover 12 can be arbitrarily changed.

The arm portion 20 extends in the front-rear direction X from the housing portion 10. The arm unit 20 includes an arm unit main body 21 disposed outside the housing 10 and a slide arm 22 connected to the arm unit main body 21 and disposed inside the housing 10.
The arm portion main body 21 and the slide arm 22 are connected straight in one direction via the pivot shaft 30. For this reason, when the arm portion main body 21 is turned, the slide arm 22 is also turned in the same turning direction about the turning shaft 30. A resin bearing is adopted for the rotating shaft 30.

As shown in FIG. 1, the exercise device 1 also includes an auxiliary arm 23 rotatably supported at one end of the arm 20 in parallel with the rotation surface of the arm 20.
An end portion of the auxiliary arm portion 23 is connected to one end portion of the arm portion main body 21 by an auxiliary rotation shaft 31.

The auxiliary arm portion 23 extends downward from one end of the arm portion main body 21 by its own weight, and is rotatable around the one end portion of the arm portion main body 21.
The length of the auxiliary arm portion 23 is shorter than that of the arm portion main body 21. The arm 20 and the auxiliary arm 23 are made of steel. In addition, the material of the arm part 20 and the auxiliary arm part 23 can be changed arbitrarily.
A resin bearing is employed for the auxiliary rotating shaft 31.

As shown in FIG. 2, the exercise apparatus 1 also includes an operation unit 40 provided at one end of the arm unit 20 in one direction. The operation unit 40 is a steel pipe material around which a soft pad is wound, and extends in the left-right direction Y.
The operation unit 40 is fixed to one end of the arm unit main body 21 of the arm unit 20 via the auxiliary arm unit 23.
That is, the operation unit 40 is fixed to an end portion of the auxiliary arm portion 23 opposite to the auxiliary rotation shaft 31. In a state where the user P grips the operation unit 40, the rotation operation of the arm unit 20 can be performed.

And as shown in FIG. 1, in this embodiment, the exercise equipment 1 is provided with the urging part 50 which urges rotation of the arm part 20. As shown in FIG.
The urging unit 50 is connected to the arm unit 20. The urging unit 50 urges the arm unit 20 to rotate when the user P operates the operation unit 40 to rotate the arm unit 20.
That is, in accordance with the turning operation of the user P with respect to the arm unit 20, a turning force in the direction in which the user P tries to turn is given to the arm unit 20.

The urging unit 50 is a spring member that connects the housing unit 10 and the arm unit 20 and exerts a tensile force F between them. The biasing portion 50 already exerts a tensile force F when the arm portion 20 extends in the front-rear direction X.
The urging portion 50 is connected to the other end portion of the arm portion 20 opposite to the operation portion 40 in one direction. That is, the urging portion 50 is connected to the slide arm 22 in the arm portion 20 and extends in the substantially vertical direction Z.

Here, in the arm portion 20, the length from one end to the pivot shaft 30 is longer than the length from the other end to the pivot shaft 30.
In other words, the length of the arm portion main body 21 is longer than the length of the slide arm 22.

The slide arm 22 is formed with a slit 25 extending along one direction. One end of the urging portion 50 is connected to a connecting piece 26 which is movable in one direction inside the slit 25.
For this reason, with the change of the posture of the slide arm 22, the connection piece 26 moves inside the slit 25 of the slide arm 22, and the extension direction of the urging portion 50 changes.

The other end of the urging portion 50 is connected to a tension adjuster 60 which is mounted on and fixed to the lower side horizontal frame 11 </ b> B of the main body frame 11.
By adjusting the tension adjuster 60, it is possible to adjust the turning power that the urging unit 50 applies to the arm unit 20.

That is, the tension adjuster 60 can raise and lower the mounting position at which the urging portion 50 is attached to the tension adjuster 60. Then, by moving the mounting position of the urging portion 50 to the tension adjuster 60 up and down, the tensile force F of the urging portion 50 which is a spring member can be adjusted.
The exercise apparatus 1 may not have the tension adjuster 60.

As shown in FIG. 2 and FIG. 3, in the exercise device set 100 using the exercise device 1, the exercise devices 1 are arranged symmetrically with respect to the user P in a symmetrical manner.
Thus, for example, the user P sitting on the chair C can hold the operation unit 40 of each of the pair of exercise devices 1 with the left and right hands, and can perform an exercise of rotating the respective arm units 20. The movement of the arm unit 20 at this time will be described in detail.

  As shown in FIG. 1, in a state in which the user P holds the operation unit 40, the user P rotates the operation unit 40 so as to draw an arc clockwise in a side view. In addition, in the case of the exercise equipment 1 arrange | positioned left-right symmetrically with respect to the exercise equipment 1 shown in FIG. 1, the operation part 40 is rotated so that a circular arc may be drawn counterclockwise by side view.

  Thereby, the auxiliary arm portion 23 pivots around the auxiliary pivot shaft 31, and the arm portion main body 21 pivots around the pivot shaft 30 such that one end thereof is directed upward. Then, the slide arm 22 pivots about the pivot shaft 30, and the connection piece 26 moves in the slit 25 of the slide arm 22.

At this time, since the urging portion 50 which is a spring member exerts the tensile force F, the urging portion 50 promotes the rotation of the arm portion 20 along the direction in which the arm portion 20 rotates. As a result, the user P can push up one end of the arm portion main body 21 upward with a small force.
When one end of the arm portion main body 21 reaches the upper end of the rotation range, the one end of the arm portion main body 21 pivots downward so as to return to the initial position. As described above, when the one end portion of the arm portion main body 21 pivots downward so as to return to the initial position, the urging portion 50 is in a state of being extended.

Then, when one end of the arm portion main body 21 reaches the lower end portion of the rotation range, the reaction in which the urging portion 50 is extended is also added, and the urging portion 50 rotates the arm portion 20 with momentum. The user P repeats this operation continuously.
In the case of the exercise apparatus set 100, the body can be easily balanced by alternately performing the left and right movements.

As described above, the exercise apparatus 1 according to the present embodiment is connected to the arm unit 20, and when the user P operates the operation unit 40 to rotate the arm unit 20, It has an urging unit 50 for urging the rotation. For this reason, when the urging unit 50 urges the user P to turn the arm 20, the burden on the user P can be reduced.
Thereby, even the person with weak muscle strength or the person with impaired physical function can use the exercise apparatus 1. And, since it is possible to train without raising the heart rate excessively, it is possible to exercise with the parasympathetic nerve working significantly.

In addition, by using the turning force from the urging unit 50, it is possible to continuously repeat movement with extremely light force, as compared with a configuration in which the weight is, for example, lifted by the arm unit 20.
That is, the user can easily repeat the reflexive movement for a long time, not an arbitrary command from the brain. During this exercise, a stretch-shortening cycle (SSC) exercise is performed by repeatedly stretching and contracting the muscle tendon complex.

  In this way, it is possible to obtain an efficient use of muscle that exerts a large power with less muscle strength. At the same time, it is possible to feed back a sense of "the body can be manipulated easily" into the brain and learn efficient exercise by repeating muscle exertion with a load lighter than the image of the user.

As a result, by recovering the elasticity of the muscles and tendons by the user and reducing the muscle tension, it is possible to gain useless force and flexible movement.
In addition, the user can improve the range of movement of the joint and acquire a constitution that is not easily fatigued.

  Generally, after initiation of walking motion, humans can continue exercising semi-automatically without being aware of motion, but I believe that this is related to a control mechanism called CPG (central pattern generator) of the spinal cord. It is done. CPG is activated by involuntarily performing alternate rhythmic exercises of the arms and lower limbs, and as a result, it partially restores the motor function and walking function of the person whose exercise and walking are difficult due to brain damage etc. There is a possibility of being

  Further, since the urging portion 50 is a spring member, it is possible to stably apply a constant force as a turning force to the arm portion 20 in the repetitive operation of the arm portion 20, and the urging portion 50 can be provided with a simple configuration. It can be realized.

  Further, in the arm portion 20, the length from one end to the pivot shaft 30 is longer than the length from the other end to the pivot shaft 30. For this reason, it is suppressed that the rotational force from the urging portion 50 connected to the other end acts largely as a moment around the rotation shaft 30, and the force required for the rotation operation at one end of the arm portion 20 is reduced. It can be suppressed.

The exercise apparatus 1 further includes an auxiliary arm 23, and the operation unit 40 is provided at one end of the arm 20 via the auxiliary arm 23.
Therefore, compared with the configuration in which the user P directly grips the one end of the arm portion main body 21 and pivots the arm portion 20, the user P facilitates the pivoting operation of the arm portion 20. be able to.

In addition, when two exercise devices 1 are arranged symmetrically on the left and right as the exercise device set 100, for example, the left and right arms are alternately moved to provide even stimulation to the respective nervous systems, which is more effective. In addition, the effects described above can be achieved.
In addition, when there is a disorder in one of the left and right nervous systems, a healthy nervous system is prompted, and effective improvement can be expected in the disordered nervous system.

Second Embodiment
Hereinafter, with reference to FIGS. 4 to 9, an exercise apparatus 2 and an exercise apparatus set 200 according to a second embodiment of the present invention will be described.
FIG. 4 is a side view of the exercise apparatus 2, and FIG. 8 is a top view of the exercise apparatus set 200 including the exercise apparatus 2 as a pair. 9 is a front view of the exercise device set 200. As shown in FIG.
In the description, the description of the same configuration as that of the first embodiment is omitted. Moreover, the description is abbreviate | omitted also about the effect similar to 1st Embodiment.

As shown in FIG. 4, in the exercise apparatus 2 of the present embodiment, the urging portion 50B is connected to a slide plate 22B formed in a plate shape.
The slide plate 22B is a component corresponding to the slide arm 22 in the first embodiment, is disposed inside the housing 10B, and is fixed to the arm main body 21B of the arm 20B.
The slide plate 22B has a substantially trapezoidal shape in which two sides extend in the front-rear direction X and the other two sides extend in the vertical direction Z in a side view, and the upper base is longer than the lower base.

The size in the front-rear direction X of the slide plate 22B is larger than the size in the vertical direction Z. Slits 25B extending along the trapezoidal legs are separately formed at both ends in the front-rear direction X of the slide plate 22B.
One end of the urging portion 50B is connected to the connecting piece 26B in the slit 25B. The urging portion 50B is a spring member and extends in the vertical direction Z. In the present embodiment, the urging portions 50B are arranged in a pair at intervals in the front-rear direction X.

Further, in the present embodiment, the urging unit 50B urges the pivoting of the arm unit 20B to restore the arm unit 20B to the original position.
That is, with the change of the rotational position of the arm portion 20B, each of the pair of urging portions 50B rotates the slide plate 22B via the slit 25B to restore the arm portion 20B to the original position.
The pair of spring members have the same size, length, and spring characteristics. Note that the two spring characteristics may be made different from each other depending on the purpose of exercise and the like.

Further, in the present embodiment, the exercise apparatus 2 includes the adjustment plate 27 that defines the initial position when the user P starts using, of the rotation range of the arm unit 20B.
The adjusting plate 27 has a fan-like shape in which the arc is located at the upper side. A plurality of adjustment holes 27A are formed in the adjustment plate 27 along the arc. Here, a fixing hole is formed in the connection plate 28 connected to the other end of the arm portion 20B.

  Then, the fixing pin 29 is inserted so as to penetrate the adjustment hole 27A and the fixing hole. That is, when the arm portion 20B is rotated and positioned at the initial position shown in FIG. 5, one of the plurality of adjustment holes 27A and the fixing hole of the connection plate 28 are communicated in the left-right direction Y By inserting the fixing pin 29, the position of the arm 20B is fixed.

In addition, it is not restricted to such an aspect, the hole 27A for adjustment is not formed in the adjustment plate 27, and the connection plate 28 and the adjustment plate 27 may be previously fixed.
In this case, as shown in FIG. 5, the connection plate 28 and the adjustment plate 27 may be fixed in a state in which the arm portion 20B extends rearward as it goes downward.

As shown in FIGS. 8 and 9, two exercise devices 2 can be arranged symmetrically with respect to the user P and used as an exercise device set 200. Thereby, in the state where the user P sits, for example, in the chair C, symmetrical motion can be performed.
The exercise performed by such an exercise apparatus set 200 will be described in detail below.

As shown in FIG. 5, the arm portion 20B is slightly rotated toward the user P, and an initial position of the arm portion 20B is defined using the adjusting plate 27. At this time, each of the pair of urging portions 50B is slightly extended from the natural length.
Then, the user P sitting on the chair C rotates the arm unit 20B by pushing the operation unit 40 forward A with the foot. At this time, by applying the weight of the foot to the operation unit 40, the arm unit 20B can be rotated with a slight force.

  When the state shown in FIG. 6 is reached, the urging portion 50B located at the front A is in an extended state, while the urging portion 50B located at the rear B is in a natural length and is in a relaxed state. By further extending the foot while applying the weight of the foot to the operation unit 40 from this state, the exercise device 2 is in the state shown in FIG.

  In the state shown in FIG. 7, the urging portion 50B located at the front A is further extended, and the urging portion 50B located at the rear B is also slightly extended from the natural length. At this time, the upper end portion of the urging portion 50B located at the rear B moves a little toward the rear B in the slit 25B.

  Then, each of the pair of urging portions 50B exerts a tensile force to apply a rotational force to the arm portion 20B. Thereby, the urging position of the arm portion 20B is restored while the urging portion 50B is contracted. As the position of the arm unit 20B is restored, the foot of the user P is flexed and extended to be in the initial posture. The user repeats this movement.

As described above, according to the exercise apparatus 2 according to the present embodiment, the urging unit 50B rotates the arm unit 20B and tries to return the arm unit 20B to the original position.
For this reason, when the urging portion 50B acts on the arm portion 20B, the turning operation of the arm portion 20B can be repeatedly performed.

Moreover, the adjustment board 27 which prescribes | regulates the initial position when the user P starts use among the rotation ranges in the arm part 20B is provided.
Therefore, by defining the initial position of the arm portion 20B by the adjusting plate 27, the entire range of the pivoting range of the arm portion 20B can be effectively used.

In addition, when two exercise devices 2 are arranged symmetrically on the left and right as the exercise device set 200, for example, the left and right legs are alternately moved to provide even stimulation to the respective nervous systems, which is more effective. In addition, the effects described above can be achieved.
In addition, when there is a disorder in one of the left and right nervous systems, a healthy nervous system can be prompted to expect effective improvement.

Third Embodiment
Hereinafter, with reference to FIGS. 10 and 11, an exercise apparatus 3 according to a third embodiment of the present invention will be described.
FIG. 10 is a side view of the exercise apparatus 3, FIG. 11 (a) is a top view of the exercise apparatus 3, and FIG. 11 (b) is a top view of the exercise apparatus 3.
In the description, the description of the same configuration as that of the first embodiment is omitted. Moreover, the description is abbreviate | omitted also about the effect similar to 1st Embodiment.

As shown to FIG. 10 and FIG. 11, the exercise equipment 3 of this embodiment is exhibiting the shape of a motorcycle machine.
That is, the exercise apparatus 3 includes a handle 80 and a saddle 81 extending upward from the housing 10C, a crank 82 rotatably supported relative to the housing 10C, and a pedal 83 connected to the crank 82. Is equipped.

The pair of cranks 82 function as an arm in the exercise apparatus 3, and the pedals 83 function as an operation unit in the exercise apparatus 3.
The crank 82 and the pedal 83 are arranged in a pair so as to be symmetrical in the left-right direction, and rotate around the rotation shaft 30C in synchronization with each other.

Further, in the present embodiment, the urging portion 50C is a rotating member that rotates with the rotation of the rotation shaft 30C. The urging portion 50C has a disk shape.
The urging portion 50C is connected to the pivot shaft 30C via a speed increaser 90 provided on the pivot shaft 30C and increasing the rotational speed of the pivot shaft 30C.

The speed increasing gear 90 includes a first gear 91 coaxially connected to the pivot shaft 30C, a second gear 92 coaxially connected to the urging portion 50C, and a space between the first gear 91 and the second gear 92. And a chain 93 for transmitting power. The second gear 92 is disposed A ahead of the first gear 91.
The diameter of the gear portion of the second gear 92 is smaller than the diameter of the gear portion of the first gear 91. Therefore, the rotation of the first gear 91 is accelerated in the second gear 92.
The exercise with the exercise device 3 will be described in detail below.

  With the user P sitting on the saddle 81, the foot is placed on each pedal 83 (operation unit). Then, when the weight of the foot is applied to the pedal 83, the crank 82 (arm portion) rotates even if no force is applied. At this time, the first gear 91 connected to the pivot shaft 30C is rotated, and this rotation is transmitted to the second gear 92 via the chain 93 in a state of being accelerated. Then, the urging unit 50C connected to the second gear 92 is rotated.

  When the urging unit 50C rotates, a moment of inertia is generated in the urging unit 50C. Due to this moment of inertia, the urging unit 50C continues rotation so as to maintain the rotational speed. By the rotation of the urging unit 50, the second gear 92 is rotated, the rotational force is transmitted through the chain 93, and the first gear 91 is rotated. Thereby, the pedal 83 is provided with a turning power. For this reason, the user P can continuously rotate the pedal 83 around the rotation shaft 30C with almost no application of the pedal 83.

As described above, according to the exercise apparatus 3 according to the present embodiment, the urging portion 50C is a rotating member that rotates with the rotation of the rotation shaft 30C. For this reason, the rotation of the arm portion 20 is promoted by the moment of inertia generated as the rotation member rotates.
Thereby, even the person with weak muscle strength or the person with impaired physical function can use the exercise apparatus 3. And, since it is possible to train without raising the heart rate excessively, it is possible to exercise with the parasympathetic nerve working significantly.

  Further, the urging portion 50C is connected to the pivot shaft 30C via the speed increasing device 90. For this reason, the rotation moment of the rotation shaft 30C is accelerated and transmitted to the urging unit 50C, whereby the inertia moment of the urging unit 50C can be increased. Thus, the operation of rotating the arm unit 20 can be continuously performed with a smaller force.

  Further, the arm portions 20 are arranged in a pair so as to be symmetrical left and right, and rotate in synchronization with each other. For this reason, it is possible to exhibit the above-mentioned effect more effectively by moving the left and right legs alternately and applying stimulation to each nervous system evenly. In addition, when there is a disorder in one of the left and right nervous systems, a healthy nervous system can be prompted to expect effective improvement.

As mentioned above, although embodiment of this invention was described with reference to drawings, a specific structure is not limited to this embodiment.
For example, in the first embodiment and the second embodiment, a configuration in which two exercise devices 1 and 2 are simultaneously used as the exercise device set 100 and 200 is shown, but the present invention is not limited to such an aspect. The exercise devices 1 and 2 may be used alone.

  In the first and second embodiments, when the exercise apparatus set 100, 200 is used, the user P is used while sitting on the chair C. However, the present invention is limited to such an embodiment. I can not. The user P may use the exercise apparatus set 100, 200, for example, in an upright position with one leg or both legs.

  Moreover, although the structure which used the spring member as the urging parts 50 and 50B was shown in 1st Embodiment and 2nd Embodiment, it is not restricted to such an aspect. As the urging units 50 and 50B, as long as they are mechanisms that generate a turning force that urges the turning of the arm units 20 and 20B, a configuration other than a spring member may be used.

  Moreover, in 2nd Embodiment, although the exercise equipment 2 showed the structure provided with the adjustment board 27, it is not restricted to such an aspect. The exercise device 2 may not include the adjustment plate 27.

  Moreover, although the structure provided with the speed-up gear 90 comprised by the gear and the chain 93 was shown in 3rd Embodiment, it is not restricted to such an aspect. The speed increaser 90 may be configured by a pulley and a timing belt, or the exercise apparatus 3 may not include the speed increaser 90.

  Moreover, in 3rd Embodiment, although the structure provided with the rotation member as the biasing part 50 was shown, it is not restricted to such an aspect. The rotation of the arm 20 may be urged by the moment of inertia of the arm 20 itself which rotates with the rotation of the rotation shaft 30C.
