Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an exercise machine that treats and prevents stiff shoulders and lower back pain, loosens muscles, and improves blood circulation by torsion, inversion, eversion, and tension of joints.

[Prior art]

As exercises for training muscles, rowing machine for abdominal muscle exercise and chest expander for chest exercise are well known. In addition, leg exercises designed to train and develop muscle strength for specific groups, such as bicycles, have already been put into practical use.

However, until now, there has been no single machine that can strengthen muscles, treat or prevent stiff shoulders and lower back pain, etc.

[Problem that the invention seeks to solve]

The above-mentioned conventional exercise machines designed for each group require a large space to install each, which poses problems not only in homes but also in terms of space, and also in terms of price. There was no other option than to provide it in public facilities such as gymnasiums. Therefore, it is inconvenient that it cannot be done easily and easily.

[Means for solving problems]

In view of these circumstances, the present invention aims to solve this problem by using a single machine to strengthen muscle strength in the lumbar region of the body, twisting the upper body, stretching the abdominal muscles, etc., and also adjusting the speed of twisting, etc. It is provided for the purpose of treatment and prevention of lower back region by performing it according to the body and degree of fatigue.

〔Example〕

Next, an embodiment of the exercise machine according to the present invention will be described based on the drawings.

In the first embodiment shown in FIGS. 1 to 5, 1 is a base fixed on a case 2, and three gears 3, 3a, 3b are meshed with the upper surface of the base 1. It is arranged. The gear ratios of the gears 3, 3a, and 3b are 1:2:1, and the drive side gear 3 in the center is made larger.

Further, an integral disc 4 is fixedly provided on the upper surface of the driving gear 3, and the shaft 5 of the driving gear 3 is supported with its lower part inside the case 2. Both gears 3a and 3b are rotatably supported by the base 1. The shaft 5 of the gear 3 is
A sprocket 6 is fixed to the end of the case 2, and a chain 8 is suspended between the sprocket 7 and a sprocket 7 which is oppositely supported in the case 2. The chain 8 is moved in the left and right direction.

The chain 8 is connected to the tip of a piston rod 10 from a cylinder 9 fixed to the case 2 by an appropriate means. The cylinder 9 is a means for driving the disk 4, and sensors (not shown) provided inside and outside the cylinder 9 monitor the movement of the cylinder piston rod 10, thereby controlling the cylinder 9. . Further, the cylinder 9 is provided with a knob a and a knob b for speed setting, and the movement of the piston rod 10 inside the cylinder 9 is monitored by the sensor described above, and the speed when the rod 10 is retracted (pushed in) and extended is monitored. is controlled by the sensor to be constant. Further, meters 11a and 11b are attached to each of them to indicate the muscle strength of the exercise.

Support rods 12 and 12a, each having one end connected to a shaft, are attached to the gears 3a and 3b, so as to support the driven wheel A riding on the disk 4 on the gear 3.

6 and 7 show another embodiment, in which two gears 3, 3a with a gear ratio of 1:1 are used, these gears 3, 3a are meshed and arranged on the base 1, and the drive side The gear 3 has a disk 4 on the upper surface as in the first embodiment.
Furthermore, a sprocket 6 is provided at the bottom of the shaft 5 as described above, and a chain 8 suspended from this sprocket is connected to a piston rod 10 from a cylinder 9.

In addition, the lower part of a support rod 14 having a handle 13 on the upper part is connected to the shaft on the other gear 3a side, and the disc 4
While supporting the exercised person A above with both hands, the user rotates the handle 13 clockwise and at the same time causes the disc 4 to rotate counterclockwise, that is, in the opposite direction, to perform a body twisting motion, thereby reducing tension, strengthening muscles, and reducing shoulder stiffness. prevention of back pain,
Used for treatment.

8 to 10 show still another embodiment, in which two gears 3a and 3b with a gear ratio of 1:1 are meshed and arranged on the base 1, and one drive side gear 3a is arranged in each of the embodiments described above. It is connected to cylinder 9 as in the example. Further, on both gears 3a and 3b, there are disks 4a and 3b, respectively.
4b is attached integrally, and these disks 4a, 4
This is used to prevent and treat lower back pain and improve posture by placing the feet on the person's body as if straddling it, standing and doing internal and external rotations, stretching the calves and Achilles, and exercising the muscles in the joints.

[Effect]

As is clear from the above configuration, in the case where three gears are used, the present invention is performed when the exercised person A stands with his or her body on the central disc 4, holds left and right grips, and internally rotates one shoulder. Due to the meshing of the gears, the other rotates outward at the same time. Therefore, by doing this alternately, the shoulder joint is exercised. In order to keep the movement of the joint constant, use the knobs a and b provided on the driving cylinder 9 side.
Set. If the piston rod of the cylinder 9 is set to 0 degrees/second so that it does not shrink, the disc will not rotate and the person on the disc will not make any joint movements. Therefore, the muscle strength in that state is shown on the meter. In addition, when the rotational speed of the disk is set to 60 degrees/second using knobs a and b on the cylinder side, which are the drive source of the disk, this rotational speed is detected by sensors placed inside and outside the cylinder 9, which determine the movement of the piston rod 10. The speed is monitored and controlled by the cylinder regardless of the force exerted by the person on the disk (communication between the sensor and cylinder occurs at a frequency of 300 times/second), and the rotation speed of the disk is 60
Keep degree/second. Also, the muscle force exerted at 60 degrees/second is shown on the meter, and this can be represented by the diagram in FIG. In this table, the length of time indicates the range of motion of the joint, and counterclockwise rotation is better than clockwise rotation. That is, it has been observed that it can be twisted.
Also, when we compare the forces at the peak, we see that the force is stronger when turning clockwise, and when we compare the shapes of the curves, we see that the peak occurs earlier when turning clockwise than when turning counterclockwise. Therefore, by adjusting knobs a and b to give changes, it is possible to perform exercise at arbitrarily different speeds.
Therefore, when the shoulder is adducted, the front muscles are activated,
At the same time, the electrical activity of the medial everting muscles decreases and they are stretched.

Figures 6 and 7 are for stretching and strengthening muscles and abdominal muscles, and treating stiff shoulders and lower back pain, while Figures 8 to 10 are for treating lower back pain and improving posture.

〔effect〕

As described above, the present invention arranges a plurality of gears meshing with each other on a base, and connects the driving gear to a cylinder whose speed can be adjusted to provide resistance to rotational movement from the driving gear. It evaluates range of motion and muscle strength, and is highly effective in treating and preventing stiff shoulders, abdominal muscles, and lower back pain, as well as promoting blood circulation and maintaining health.
