Description

The present invention relates to a posture check tool you confirm whether or not the proper attitude.

It is known that when the body is out of balance, it affects the physical condition and is itself a sign of illness. That is, the state of physical balance can be used for the detection of disorders and illnesses. Therefore, a technique for measuring the body balance and determining the state thereof has been proposed. For example, in Patent Document 1, three or more load sensors are provided on a stepping stone on which a subject stands, and the center of gravity balance ability of the subject is determined from their outputs. According to the technique of Patent Document 1, it is possible to determine whether or not the balance of the center of gravity of the subject is good, and the determination can be used for adjusting or treating the balance of the center of gravity, detecting a disease, or the like.

Based on many years of research, the inventor of the present invention (hereinafter abbreviated as the inventor) has found that the ear canal, shoulder ridge, center of gravity (slightly before the cuboid bone), femoral head, and both feet are not in the conventional well-balanced posture. It was found that the state in which the line connecting the midpoints of each of the cuboid bones is vertical when viewed from the side of the body is a balanced and proper posture, and this is called the center of gravity posture. There is. If the inventor can maintain the center of gravity posture, he / she can prevent poor physical condition due to imbalance, and in the state of the center of gravity posture, unnecessary force does not act on the body and he / she is very relaxed. We have also obtained the knowledge that it will be in a state. Therefore, in the state of the center of gravity, the stress on the brain is reduced, and it can be expected that the original ability can be brought out.

In this way, maintaining the posture of the center of gravity has various advantages. However, it is not easy to confirm whether or not the current posture is the center of gravity posture. In particular, since the posture of the center of gravity is different from the conventional general well-balanced posture, it is not possible to determine whether or not the posture is the posture of the center of gravity by a technique such as Patent Document 1.

In addition, in order to maintain the posture of the center of gravity, it is desirable to let the body remember the posture of the center of gravity. In that case, for example, it is repeated to perceive the posture of the center of gravity in what posture. However, in the technique of Patent Document 1, since the balance of the center of gravity is determined after the fact, it is not possible to determine the suitability of the balance of the center of gravity in real time. In addition, although it is possible to see the appropriateness of the balance of the center of gravity and the swing locus of the center of gravity, it is difficult for the body to remember whether or not the posture of the body at that time is appropriate.

The present invention has been made in view of the above problems, its object is to provide a posture state check tool that can be confirmed in a timely manner whether the body posture is proper with a simple structure ..

As shown in the figure, the main body 1 is composed of a substantially rod-shaped shaft S and two disk-shaped members D. The shaft S has a rod shape having a substantially uniform diameter, but two small diameter portions S1 are formed at positions equidistant from both ends. The two disc-shaped members D have the same shape, and a hole D1 through which the shaft S is inserted is formed in the center. In the present embodiment, the shaft S has a length of 220 mm, a diameter other than the small diameter portion S1 of 40 mm, and a diameter of the smallest diameter portion of the small diameter portion S1 of 32 mm. Further, the small diameter portion S1 is formed from a position of 10 mm to a position of 70 mm from the end portion of the shaft S, and the portion having the smallest diameter thereof is located at a position of 40 mm from the end portion of the shaft S. The disk-shaped member D has a diameter of 100 mm, a minimum thickness of 6.5 mm, and a maximum thickness of 15 mm. Further, the diameter of the hole D1 of the disk-shaped member D is 40 mm, which is the same as the diameter of the shaft S.

When assembling the posture confirmation tool A, both ends of the shaft S are inserted into the holes D1 of the respective disc-shaped members D. At this time, a gap is formed between the two disc-shaped members D, and the gap is inserted so that the center of the gap and the center of the shaft S coincide with each other in the axial direction. With this configuration, the two disc-shaped members D are located at the same distance from the end of the shaft S, and the axis of the shaft S and the axis of the two disk-shaped members D are concentric. In the present embodiment, the disk-shaped member D constitutes the disk-shaped portion 11.

At this time, if the outer diameter of the shaft S and the inner diameter of the disc-shaped member D are set to be the same diameter, the disc-shaped member D can be substantially fixed. As a matter of course, the disk-shaped member D may be fixed more firmly by using another member.

〔hoop〕
As shown in FIG. 1, the hoop 2 is formed in a flat plate ring shape. The thickness of the main body portion of the hoop 2 (the portion where the thin portion 21 described later is not formed) is preferably 7.5 mm to 8 mm, and is 8 mm in the present embodiment. Therefore, the thickness of the hoop 2 is smaller than the axial length of the connecting portion 12. The preferable value of the axial length of the connecting portion 12 is related to the thickness of the hoop 2, and the thickness of the hoop 2 + about 2 mm, that is, a clearance of about 1 mm is formed on both sides of the hoop 2. Is preferable. The radial thickness of the hoop 2 (difference between the outer diameter and the inner diameter) is preferably 30 mm to 35 mm, and is 32 mm in the present embodiment.

FIG. 3 is a cross-sectional view taken along the line III-III of FIG. 1 and represents a cross section of the hoop 2. As shown in the figure, a thin portion 21 is formed on the inner peripheral side end of the hoop 2 over the entire circumference. Specifically, the thin portion 21, the hoop 2 axial direction is formed (horizontal direction in the drawing) on both sides, is formed as an inclined portion 21a which becomes thin as the inner peripheral side (upper side in the drawing). Further, a flat portion 21b formed as a flat surface is formed between the inner peripheral sides of the two inclined portions 21a. In the present embodiment, the surface of the inclined portion 21a is a curved surface, but it may be a flat surface. The length of the flat portion 21b in the axial direction is preferably about 1.5 mm to 2 mm, and is 2 mm in the present embodiment.

〔how to use〕
Next, a description will be given of how to use the attitude check tool A. First, with the hoop 2 hung on the connecting portion 12 of the main body 1 (see FIG. 1), the two grip portions 13 are gripped by the left and right hands, respectively. The grip may be either forward or reverse, and the grip may be easier for the user to use. Therefore, it is possible to use a posture check tool A in a more relaxed state. Since the grip portion 13 is formed with a small diameter portion 13a, it can be gripped stably with either a forward hand or a reverse hand. In this state, both arms are moved so that the hoop 2 makes a circular motion while eccentric around the connection portion 12. FIG. 4A is a view of the state at this time as viewed from the axial direction of the main body 1 on the right hand side.

The rotation direction of FIG. 4A is referred to as forward rotation, and the hoop 2 is clockwise in the axial direction of the main body 1 on the right hand side. However, the rotation is not limited to the front rotation, and the user who rotates the hoop 2 counterclockwise in the axial direction of the main body 1 on the right hand side and the rear rotation is easier to rotate may rotate the hoop backward. .. According to the research of the inventor, the user who rotates forward tends to have a posture of pelvic anteversion, hip extension, knee joint extension, ankle joint flexion, lumbar extension, and thoracic spine extension. It has been found that there is a tendency for pelvic tilt, hip flexion, knee flexion, ankle extension, lumbar kyphosis, and thoracic kyphosis.

When the rotational movement of the hoop 2 is started, while maintaining the rotational movement, the hoop 2 is searched for a posture in which the hoop 2 can be rotated without difficulty, and the hoop 2 is unconsciously rotated even if the hoop 2 is not consciously rotated. Search for a rotating posture. That is, instead of searching for the hoop 2 "turning", the hoop 2 "turning" posture is searched. Through many experiments, the inventor has found that the posture when this "hoop 2 turns" is the posture of the center of gravity. That is, in the center-of-gravity posture, when the hoop 2 is at the solid line position in FIG. 4A, that is, when the center of gravity of the hoop 2 is at the position closest to the body, when the position of the center of gravity is extended vertically downward, both feet It intersects the center of the line connecting the cubes. In such a posture, only the minute movement of the center of gravity of the body unconsciously transmitted to the grip 13 is transmitted from the outside, and the circular motion is continued mainly by the mutual conversion between the potential energy and the kinetic energy due to the movement of the center of gravity. Can be made to. That is, when "the hoop 2 turns", the posture is the center of gravity posture. At this time, as shown in FIG. 4B, the hoop 2 does not shift in the axial direction and has a stable eccentric circular motion.

The above-mentioned minute movement of the center of gravity of the body is caused by the following mechanism. When a rotational movement is caused on the hoop 2, a force always acts on the body in the direction opposite to the rotation direction of the hoop 2. This force is unknowingly perceived by the brain, which unknowingly moves the center of gravity of the body to a position where the rotation of the hoop 2 can be maintained.

Thus, according to Ru engages the present invention posture check tool A, by causing rotational movement relative to the hoop 2, in unconscious level the user does not perceive, reflectively adjust the center of gravity of the body It can be repeated. As a result, the posture balance of the body can be potentially adjusted, and the posture of the center of gravity can be stabilized.

In order to properly confirm whether or not the posture is the center of gravity posture, it is preferable that the hoop 2 does not rotate properly except for the action of an appropriate force. Therefore, axial length of the connecting portion 12 of the put that attitude check tool A in this embodiment is larger than the thickness of the hoop 2. Further, as shown in FIG. 4, the facing surface 11a of the disk-shaped portion 11 is inclined so as to be outward toward the outer side in the radial direction. With such a configuration, if the forces transmitted to the two grip portions 13 are not equal, the hoop 2 will rattle in the axial direction, or the hoop 2 will meander and make a circular motion. Connect (see FIG. 4 (c)). Further, since the thin portion 21 is formed at the inner peripheral end of the hoop 2, when an appropriate force is applied to the grip portion 13, the flat portion 21b comes into contact with the main body 1, and the hoop 2 is appropriate. It becomes easier to make a good circular motion. On the other hand, when an appropriate force is not applied to the grip portion 13, the inclined portion 21a comes into contact with the main body 1, so that the hoop 2 rattles in the axial direction or the hoop 2 meanders and makes a circular motion. It becomes easier to do.

As described above, when the hoop 2 is not in the center-of-gravity posture, the hoop 2 does not make an appropriate circular motion, so that it can be perceived that the hoop 2 is not in the center-of-gravity posture. Further, in order to make the hoop 2 that does not perform a proper circular motion perform a proper eccentric circular motion, it is necessary to consciously apply a force to the grip portion 13, but in this case as well, the hoop 2 is consciously moved. Since it is possible to perceive that it is rotating, it is also possible to perceive that it is not in the center of gravity posture.

Inventors, in the case of people who are not familiar with the use of engaging Ru posture check tool to the present invention, by using the axial direction length is shorter have posture check tool connecting portion 12, the hoop 2 is disk-shaped It has been found that it is difficult to confirm the proper posture because it is easy to hit the member D and the body is forced to be aware of it. Therefore, in the case of a person who is not familiar, to use the axial length long have posture check tool of the connecting portion 12, in a state where no body force from entering, to experience a sense of hoop 2 rotates comfortably It is preferable to let the brain remember the state. Therefore, if a person not familiar uses posture state check tool is a two disk-like member D is slid outward, setting a longer axial length of the connecting portion 12. On the other hand, for those who are accustomed to using it, it has been found that it is easier to use if the length of the connecting portion 12 in the axial direction is short (close to 10 mm, which is a preferable length), so that the person is accustomed to using it. Therefore, the length of the connecting portion 12 in the axial direction may be gradually shortened.

As described above, when using the posture state check tool A, since the hoop 2 is eccentrically circular movement in front of the chest, so that the hoop 2 does not contact the body, the outer diameter varies depending on the user hoop It is desirable to be able to select 2. For example, hoops 2 having outer diameters of 320 mm, 300 mm, and 280 mm are prepared, and an appropriate hoop 2 is selected according to the length of the radius of the user and the like.

Stance state check tool A can be created at the beginning various materials wood or resin, by creating a tree, because the relaxation effect due to hand or the like is expected, preferred. However, when it is made of wood, it is difficult to completely match the left and right weights of the main body 1. On the other hand, in order to accurately confirm the posture of the center of gravity, it is desirable that the left and right weights of the main body 1 are completely matched. It has also been found that the weight of the easy-to-use main body 1 varies from person to person. Therefore, it is also preferable to provide the grip portion 13 with a balance adjustment space 13b for inserting a minute weight of about several g. For example, as shown in FIG. 5, a minute hole is formed as a balance adjustment space 13b on the end face outside the axial direction of the grip portion 13, a weight W of about several g is put in the balance adjustment space 13b, and the lid 3 is closed. Cover.

In this way, by using the attitude check tool A of the present invention, it is possible to easily confirm whether or not the gravity center position. In addition, by repeating this, the body can memorize the posture of the center of gravity and form a sense of the center of gravity. In addition, in the state in the center of gravity position, to become a state in which the body is relaxed, by checking the center of gravity posture by using the attitude check tool A, it can also be used to alleviate the tension of the body and spirit ..

In addition, through the inventor's experiment, it was confirmed that the left and right brains of the user are working well in a state where the body is in the center of gravity posture and the hoop 2 is rotating in a well-balanced manner in the central part of the main body 1. ing. It has also been confirmed that many α waves indicating a state of concentration in relaxation are emitted from the brain waves in such a state. The alpha wave emitted by the right brain is transmitted to the left brain through the corpus callosum, amplified in the left brain, and transmitted to the right brain again through the corpus callosum to form a circulation. By continuing this circulation, consciousness can be concentrated and the body can be in a state suitable for exerting various abilities.

It is also known that the conscious brain and the subconscious brain can be integrated in a state where a lot of α waves are emitted, and that the learning effect is dramatically enhanced by learning and practicing in this state. According to engagement Ru posture check tool A in the present invention, the operation and awareness brain to be Mawaso hoop 2, it is possible to integrate the operation of the subconscious brain that hoop 2 turns, under this integration state You can experience a simulated state of concentration.

When the hoop 2 is in a state of "turning" like an inertial motion, the center of gravity line passing through the center of gravity of the body and the body support line against gravity coincide with each other. In this state, a relaxed body and brain state can be formed.

That is, Ru engages the present invention posture check tool A is not only to check whether the body is in the center of gravity position, also it is used to the state of being relaxed mind and body, and pulled out easily state physical performance can do.
