Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for assisting reverse rotation of left and right arms and / or legs, and more particularly to left and right arms and / or legs for stimulating and working both brains. The present invention relates to a training tool for exercises in which is rotated in the reverse direction.

[0002]

2. Description of the Related Art It is said that by actively working both the right and left brains, creativity and imagination are enriched. It is also said that daily habits of actively working the right and left brains are effective in preventing the onset of stroke, which is one of the three major adult diseases, suppressing the sequelae, and preventing blurring.

By the way, it is easy to simultaneously rotate both arms in the same direction, but it is not easy to simultaneously rotate them in opposite directions. This is because the arms do not make such movements on a daily basis. Conversely, such movements that are not performed on a daily basis are considered to stimulate both brains.

[0004]

As described above, the simultaneous simultaneous rotation of the arms in the opposite directions is suitable for stimulating both brains. However, even if such exercises are practiced on a daily basis, there is no way to get along. Also, no suitable device for assisting such exercise has been proposed. Therefore, the present invention provides the above two arms,
It is another object of the present invention to provide a suitable assisting device for reminding the body of the simultaneous simultaneous rotational movements of the legs in the opposite directions.

[0005]

According to the present invention, there is provided a rotating shaft driven by a right hand and a rotating shaft driven by a left hand, the rotation of one of which being rotated in the opposite direction to the rotation of the other. A right and left arm reverse rotation motion assisting device, and a rotation shaft driven by the right leg and a rotation shaft driven by the left leg, and rotation of one of the rotation shafts is performed by the other. This problem has been solved by a reverse rotation motion assisting tool for the left and right legs, which can be transmitted to the rotation shaft as reverse rotation. Preferably, it is possible to selectively switch between transmitting and not transmitting the rotational force from the one rotating shaft to the other rotating shaft.

Embodiments of the present invention will be described with reference to the accompanying drawings. First, the embodiment shown in FIGS. 1 and 2 will be described. This embodiment is for arm rotation. In FIG. 1, reference numeral 1 denotes a base, and shaft support walls 2, 3 are provided upright at both ends. Reference numerals 4 and 5 denote rotating shafts that are supported between the shaft supporting walls 2 and 3.
Preferably, one or both of the rotating shafts 4, 5 are movable in the axial direction. In the illustrated example, only the rotating shaft 4 is movable, and by loosening the fixing screw 6 that is screwed into the shaft supporting wall 2 and reaches the rotating shaft 4, the movable shaft 4 can be moved.

Gears 7 meshing with each other are attached to the rotating shafts 4 and 5.
8 is attached. When one or both of the rotation shafts 4 and 5 are made movable, the movement makes it possible to release the meshing state of the gears 7 and 8 (see the phantom line in FIG. 1). The opposite ends of the rotating shafts 4 and 5 are the supporting walls 2 and 3
And handle arms 9 and 10 provided with grip handles 11 and 12 respectively. Reference numeral 13 denotes a support bar extending between the shaft support walls 2 and 3.

In the above configuration, when the grip handle 12 is gripped with the right hand in a state where the gears 7 and 8 are meshed, the grip handle 11 is gripped with the left hand, and the handle arm 10 is turned with the right hand, the rotational power is increased. Although transmitted to the rotating shaft 4 via the gears 7 and 8, the rotating direction is reversed between the rotating shaft 4 and the rotating shaft 5.

At the beginning of training, force is applied to only one of the grip handles 11, 12 and the other is only received, so that rotation of one forces the other to rotate in the opposite direction. Even if the user initially feels uncomfortable with the movement, the reversing left and right operation is not unnatural as the operation is repeated, and the user does not feel uncomfortable. This alone can give a good stimulus to the brain, but when it gets used, the rotating shafts 4 and 5 are shifted to release the meshing relationship of the gears 7 and 8, and the rotation of one handle arm 9 causes the other handle arm to rotate. Not to be transmitted to the system 10. If you do so, both grip handles 1
The handle arms 9 and 10 cannot be rotated in opposite directions unless the first and second members 1 and 12 are independently applied with opposite forces. It is considered that the stimulus to the brain due to this exercise is greater than when the gears 7 and 8 are meshed.

The embodiment shown in FIG. 3 is for leg rotation,
On the base 1, a box 15 incorporating the rotating shafts 4a, 5a, gears 7a, 8a, and pedal arms 9a, 10a having the same structure as described above is installed.
Is attached. In this case, the pedal arm 9a,
Foot pedals 17 and 18 are attached to 10a.

In this embodiment, when the user sits on the seat 16 and depresses the pedals 17 and 18, the pedal arm 9 is turned on.
Practice by rotating the motors a and 10a in the same manner as in the embodiment described above, and practice by rotating the rotating shafts 4a and 5a free after removing the gears 7 and 8 after getting used.

The embodiment shown in FIGS. 4 and 5 is a combination of the above two embodiments, and there are a case where the arm rotation unit and the leg rotation unit are independent of each other, and a case where both units are interlocked. 4 and 5 show the latter case,
A first conductive belt 21 is wound around a rotation shaft 5 of the arm rotation unit and a first belt shaft 20 passed over the base 1. A second conductive belt 23 is wound around the first belt shaft 20 and the second belt shaft 22 which is further passed over the base 1, and further between the second belt shaft 22 and the rotating shaft 4a. Is wound around the third conduction belt 24.

In this case, the rotation of the rotating shaft 5 is controlled by the first conductive belt 21, the second conductive belt 23 and the third conductive belt 24.
And transmitted to the rotating shaft 4a via the gears 7a and 8a. Therefore, it is possible to force the remaining limb to perform an unfamiliar operation that is not normally performed by the rotation operation of either the right hand or the left hand, or the right leg or the left leg.

FIGS. 6 and 7 show the above operation performed by the power of the fingertip while stimulating the fingertip where the acupoints are gathered. In this case, one gear shaft 26 is supported by the support walls 2 and 3 on the base 1. A first bevel gear 27 is fixed to an intermediate portion of the gear shaft 26, and a second bevel gear 28 always meshes with the first bevel gear 27. The shaft of the second bevel gear 28 is supported by a bearing 30 installed on a horizontal plate 29 disposed between the support walls 2, 3.

Reference numeral 31 denotes a sliding cylinder provided with a third bevel gear 32 at an end. A gear shaft 26 is loosely inserted at the center of the sliding cylinder, and can be moved along the gear shaft 26 by loosening the fixing screw 6. The third bevel gear 32 is configured to mesh with the second bevel gear 28 when the sliding cylinder 31 moves forward most. The sliding cylinder 31 is slidably supported in a linear bearing 33 installed on the shaft supporting wall 2, and a rotating arm 34 is fixed to an outer end thereof. A similar rotating arm 34a is also fixed to the outer end of the gear shaft 26 protruding from the shaft support wall 3.

Disk shafts 35, 35a are fixed to the ends of the rotating arms 34, 34a, respectively.
At 5, 35a, drive disks 36, 36a having finger holes 37 corresponding to five fingers are rotatably supported. Preferably, the finger pads 38, 38a are further rotatably attached to the disk shafts 35, 35a. The finger pads 38, 38a are stoppers for fingertips inserted through the finger holes 37.
And a stimulating plate for the fingertip, and if necessary, unevenness is formed on the plane contacted by the fingertip.

In the case of this embodiment, the drive disk 3
A fingertip is inserted into a finger hole 37 of the sixth and 36a, and the rotating arms 34 and 34a are rotated around the gear shaft 26 by the force of the fingertip. The second bevel gear 28 and the third bevel gear 32 are meshed. In this case, the rotation of one rotating arm is transmitted to the other rotating arm, and when they are not engaged, both rotating arms 34 and 34a rotate independently.

[0018]

As described above, the present invention makes it possible to forcibly perform a simultaneous reverse circular motion on the left and right hands or legs by using the assist device, and after repeating the practice. By releasing the forced transmission mechanism, it is possible to reproduce the image experienced by practice with your own control, so that anyone can easily and enjoy the right and left simultaneous reverse circles that are useful for activating the right and left brains It has the effect of making it possible to exercise. In addition, this rotation practice not only has the effect of exercising elbows and wrists, promoting blood circulation of hands and arms, and reducing shoulder stiffness.
