It is known that Tanda exists in the back of the abdominal muscles and can stabilize the lumbar spine and strengthen the psoas major and psoas minor muscles by increasing the abdominal pressure while being aware of the area. The intervertebral disc is stretched by the increase in abdominal pressure conscious of Tanda, and the stretching effect makes the lumbar spine spacing appropriate, and the back pain is relieved extremely effectively, and not only the abdominal slack and the stoop are improved, but also the motor function. Also recovers or improves.

However, it is generally difficult to raise abdominal pressure consciously of Tanda, and the current situation is that Tanda strengthening is not widely used as a general training method.

On the other hand, for example, in Patent Document 1 (Japanese Unexamined Patent Publication No. 2009-247661), a vibration signal created by an automatic repeat timer and a vibration motor is generated at a position of the umbilical cord Dantian at regular intervals by a microcomputer such as a PIC and an oscillator. The Umushita Dantian Reinforcement System Band, which is used to perform each person's ingenuity, is disclosed at each time.

In the umbilical cord dantian strengthening system band described in Patent Document 1, the psoas major muscle and the iliopsoas muscle become stronger by being aware of the umbilical cord dantian by the automatic repeat vibration signal, and in addition to smooth excretion, the abdomen It is said that increasing the number of ceremonial breaths will stabilize the patient mentally.

Further, in Patent Document 2 (Japanese Unexamined Patent Publication No. 2013-94336), the wearer's body is along the line connecting the anterior superior iliac spine and the fifth lumbar spine in the lateral view of the trunk in a resting position. A main body surrounding the lumbar region, a bag-shaped storage portion arranged between the left and right anterior superior iliac spines of the wearer in the main body portion, and a bag-shaped storage portion stored in the storage portion to inject gas. Disclosed is a supporter comprising an swelling portion that increases the volume thereof, wherein the swelling portion presses the wearer's iliac toward the wearer's fifth lumbar vertebra.

In the supporter described in Patent Document 2, the wearer's abdomen is pressed from the front to the back and upward, a repulsive force is exerted on the rectus abdominis muscle located in the anterior abdomen, and a contraction force is applied to the inner muscle of the abdomen connected to the rectus abdominis muscle. Can be used to train the inner muscles of the wearer's main parts, prevent the wearer's back pain, improve the stability of the wearer's lumbar spine, and provide a pain-relieving effect for the wearer with back pain. You can get it.

In the following description, the same or corresponding parts may be designated by the same reference numerals, and duplicate description may be omitted. Moreover, since the drawings are for conceptually explaining the present invention, the dimensions of each component represented and their ratios may differ from the actual ones.

1. 1. Backrest for Tanda reinforced belt 1
<Structure of backrest 1 for Tanda reinforced belt>
The configuration of the backrest portion 1 for the Dantian reinforced belt of the present embodiment will be described with reference to FIG. FIG. 1 is a schematic view showing the configuration of the backrest portion 1 for the Dantian reinforced belt of the present embodiment.
As shown in FIG. 1, the back support portion 1 for the Dantian reinforced belt of the present embodiment has two guide portions 3 through which a band-shaped body 21 (described later) for substantially surrounding the lumbar region and the abdomen is inserted and the same. A main body 100 having two bases 5 that support the guides 3 and a flexible portion 7 that connects the two bases 5, a back pad 9 that is in contact with the wearer's back on the back side, and It is composed of.

Further, the details of the backrest portion 1 for the Dantian reinforced belt of the present embodiment will be described with reference to FIGS. 2 to 4. FIG. 2 is a front view of the backrest portion 1 for the Dantian reinforced belt of the present embodiment, FIG. 3 is a back view of the backrest portion 1 for the Dantian reinforced belt of the present embodiment, and FIG. It is a side view of the back support part 1 for the Dantian reinforced belt of this embodiment.
The main body 100 is a polypropylene part integrally formed by using an injection molding method or the like, and is a substantially rectangular plate-shaped member having a longitudinal direction L1 and a lateral direction L2. Further, the main body 100 is symmetrically configured at the center of L1 in the longitudinal direction. The short side H1 of the main body 100 preferably has a size of 70 to 90 mm, and the long side W1 preferably has a size of 140 to 180 mm. By setting the dimensions of the short side H1 and the long side W1 of the main body 100 within these ranges, it is possible to minimize obstacles to movement while ensuring supportability.

Two base members 5 serving as core members of the main body 100 are arranged at predetermined intervals in the longitudinal direction L1, and the two base members 5 are connected by the bending portion 7. Since the flexible portion 7 has a thinner plate thickness than the base member 5 and has appropriate flexibility, the main body portion 100 can be bent within a predetermined range with the flexible portion 7 as a base point.

Further, above each base member 5, a guide portion 3 having a through hole 11 that opens in the lateral direction L2 and penetrates in the longitudinal direction L1 is raised, and the through hole 11 of the guide portion 3 has a band shape. The body 21 can be inserted. As described above, since the main body portion 100 has a symmetrical structure at the center of the longitudinal direction L1, the two guide portions 3 are separated from each other at a predetermined interval.

By inserting the strip-shaped body 21 into the through holes 19 provided in each of the guide portions 3, the strip-shaped body 21 and the backrest portion 1 for the Dantian reinforced belt of the present embodiment can be connected more stably. It is preferable that the through hole 11 has a double strip-shaped body 21 that can be inserted into the through hole 11, and by using the double strip-shaped body 21, the tightening force on the abdomen can be further stabilized. At the same time, a stronger tightening force can be applied.

The through hole 11 is substantially rectangular, and the short side H2 of the through hole 11 preferably has a size of 3 to 10 mm, and the long side W2 preferably has a size of 65 to 100 mm. By setting the short side H2 of the through hole to 3 mm or more, the band-shaped body 21 of a general shaving material can be doubled and inserted, and by setting it to 10 mm or less, the inhibition to movement due to the formation of the convex portion is minimized. Can be limited. Further, by setting the long side W2 to 65 to 100 mm, a band-shaped body 21 having an appropriate width can be inserted from a small child and a woman to a large man.

Two substantially rectangular backrest pads 9 made of urethane, natural rubber, synthetic rubber, or the like are arranged inside the main body 100 (on the back surface side). The back pad 9 is arranged on the back surface of each of the two base members 5, and by contacting the back of the wearer, the back pad 9 can provide an appropriate cushioning property and further improve the adhesion. Further, since it is made of the above-mentioned material, when the back support portion 1 for the Dantian reinforced belt of the present embodiment is attached, a frictional force is generated between the back support portion 1 for the Dantian reinforced belt and the back. It can occur and suppress undesired position fluctuations.

2. How to use the backrest 1 for the Dantian reinforced belt <Strip 21>
The back support portion 1 for the Tanda reinforced belt of the present embodiment constitutes the Tanda reinforced belt by connecting with the band-shaped body 21 provided with the buckle portion 23, and is used for training. A strip-shaped body 21 suitable for use of the back support portion 1 for the main Tanda reinforced belt will be described with reference to FIG. FIG. 5 is a plan view of the strip-shaped body 21 suitable for use of the backrest portion 1 for the Dantian reinforced belt of the present embodiment.
As shown in FIG. 5, the strip-shaped body 21 used in the present embodiment is a long cloth formed in a substantially straight line, and is composed of a single layer or a plurality of layers. Further, since the band-shaped body 21 has appropriate elasticity and sufficient strength for tightening the abdomen, it is preferable to use a cotton material. As a result, unlike leather and nylon used for general training belts, water-based cleaning can be easily performed, and it is extremely easy to maintain a clean state.

One end of the strip 21 is sewn while forming a ring by folding back, for example, a predetermined length, and a ring-shaped buckle portion 23 is connected to the ring. Further, an end reinforcing tool 25 for reinforcing the end of the strip 21 is attached to the other end, and the end of the strip 21 is easily inserted into the guide portion 3 and the buckle portion 23. be able to. The end reinforcing tool 25 can be configured by, for example, folding a metal plate having a predetermined length and width and sandwiching the end portion of the strip-shaped body 21 inside. Further, the end reinforcing tool 25 is preferably formed of a metal having corrosion resistance.

The shape and size of the band 21 are not particularly limited, and it is sufficient that the wearer's abdomen (the region from the line connecting the anterior superior iliac spine and the fifth lumbar vertebra to the auxiliary bone) can be substantially completely surrounded.

Further, the thickness of the band-shaped body 21 is not particularly limited, and the thickness may be such that the band-shaped body 21 can be inserted into the guide portion 3 of the buckle portion 23 to the extent that sufficient strength for tightening the abdomen can be ensured. The band-shaped body 21 may be formed by using only the rod material, but the band-shaped body 21 may be reinforced by appropriately inserting a core material in the width direction or the longitudinal direction of the band-shaped body 21, or rubber or the like may be attached to the innermost surface that comes into contact with the wearer. It may be attached to give an anti-slip effect.

<Buckle part 23>
From the viewpoint of fine adjustment of the tightening force and simplification of the structure, the buckle portion 23 used in the present embodiment is composed of at least two annular portions, the first annular portion 23A and the second annular portion 23B. It is preferably configured and is connected to the end of the strip 21 as described above. Both the first ring portion 23A and the second ring portion 23B have substantially the same shape, and specifically, they are configured to have a predetermined thickness (thickness that does not cause deformation during tightening). It is desirable that there are no edges at the edges of the outer and inner diameters.
It is desirable that the buckle portion 23 can be separated by arbitrarily breaking the connection with the strip-shaped body 21. By making the buckle portion 23 and the strip-shaped body 21 arbitrarily separable, maintenance of the buckle portion 23 and the strip-shaped body 21 becomes easy, and cleaning of the buckle portion 23 and washing of the strip-shaped body 21 can be easily performed. ..

To fix the band-shaped body 21 using the buckle portion 23, the band-shaped body 21 is inserted into the first annular portion 23A and the second annular portion 23B, and the first annular portion 23A and the second annular portion 23B are fixed. , This is performed by generating a frictional force with the strip-shaped body 21, but if the first annular portion 23A and the second annular portion 23B have edges, the strip-shaped body 21 will be hung on the edges more than necessary. The tightening condition cannot be easily adjusted. Therefore, as described above, the buckle portion 23 is formed by using the first ring portion 23A and the second ring portion 23B having no edges, and the appropriate frictional force is applied to the first ring portion 23A and the second ring portion 23A and the second circle. It is preferable to provide fine irregularities or the like on the surface of the ring portion 23B.

Further, on one surface (the surface in contact with the abdomen) of the first annular portion 23A, with the connected strips 21 horizontally arranged, a non-slip member such as a rubber tape is placed above and below (not shown). May be pasted. Specifically, it was tightened to the body by attaching a non-slip member that exerts a frictional force when it comes into contact with the abdomen to a region other than the contact surface between the first annular portion 23A and the belt-shaped body 21. Unintentional position fluctuation of the Dantian reinforced belt can be suitably suppressed.

In the above description, the buckle portion 23 composed of the first annular portion 23A and the second annular portion 23B has been described as an example of the present embodiment, but the buckle portion 23 has a structure capable of holding the belt-shaped body 21 in a tightened state. Since the function can be generally fulfilled, for example, a conventionally known structure known as a buckle portion for a general belt can be adopted.

<How to attach the Dantian reinforced belt>
Next, using FIGS. 6 (a) and 6 (b) and 7 (a) and 7 (b), a method of mounting the Dantian reinforced belt provided with the back support portion 1 for the dantian reinforced belt according to the present embodiment. Will be described. 6 (a) and 6 (b) are views showing a procedure for attaching the Dantian reinforced belt, and FIG. 6 (a) shows the Tanda reinforced belt back support portion 1 of the present embodiment and the band state 21 connected to each other. FIG. 6B is a schematic view showing a state in which the backrest portion 1 for the Dantian reinforced belt of the present embodiment is in contact with the back and the band state 21 is surrounded by the lumbar region and the abdomen. is there.
7 (a) and 7 (b) are diagrams showing a procedure for connecting and tightening the band state 21 and the buckle portion 23, and FIG. 7 (a) is a schematic diagram showing a procedure for the first half of tightening. Yes, FIG. 7B is a schematic diagram showing the latter half procedure of tightening.

As shown in FIG. 6A, first, the band state 21 and the backrest portion 1 for the Dantian reinforced belt of the present embodiment are connected to prepare for the use of the Dantian reinforced belt. The wearer arranges the back support portion 1 for the Honda reinforced belt on a table surface or the like with the back support pad 9 facing downward, and grips the vicinity of the end reinforcing tool 25 of the band-shaped body 21 to hold the band-shaped body 21. It is inserted through the through hole 11. Since the strip 21 is a cloth made of a cotton material, even if it is constructed with a core material, the end of the strip 21 is distorted and it is difficult to insert it into the through hole 11, but it is hard. Since the end portion is sandwiched and reinforced by the end reinforcing tool 25, the strip-shaped body 21 can be easily inserted into the through hole 25.

According to the above procedure, the strip-shaped body 21 is inserted into the two through holes 11 provided in the backrest portion 1 for the Dantian reinforced belt of the present embodiment, passed through the respective guide portions 3, and then the strip-shaped body is passed along the guide portion 3. 21 is moved so that the back support portion 1 for the main Tanda reinforced belt is located substantially near the center of the strip-shaped body 21 in the longitudinal direction.

Subsequently, as shown in FIG. 6B, the wearer arranges the back support portion 1 for the Tanda reinforced belt of the present embodiment on the back side, and both ends of the band-shaped body 21 (buckle portion 23 side and the buckle portion 23 side and). The end reinforcing tool 25 side) is grasped by the left and right hands, respectively, and the waist and abdomen are surrounded by the band-shaped body 21. More specifically, the backrest pad 9 of the backrest portion 1 for the Honda reinforced belt is opposed to the body side, and it is confirmed that the band-shaped body 21 is not twisted in this state, and both of the band-shaped bodies 21 are confirmed. Surround the lumbar region and abdomen by turning the ends from the left and right to the abdominal side. At this time, if the band 21 is twisted, the lumbar region and abdomen cannot be uniformly tightened and pressed, and the training effect of Tanda is reduced. Therefore, it is desirable to check carefully.

Next, the buckle portion 23 of the strip-shaped body 21 and the end reinforcing tool 25 side are connected, the strip-shaped body 21 is tightened to the lumbar region and the abdomen, and the Tanda reinforced belt is attached to the wearer. First, as shown in FIG. 7A, the first ring portion 23A and the second ring portion 23B included in the buckle portion 23 are overlapped with each other, and the ring is fixed so as to face the abdominal side P1. The end reinforcing tool 25 side of 21 is inserted from the abdominal side P1 toward the outer side P2 inside the first annular portion 23A and the second annular portion 23B. Further, the end reinforcing tool 25 side of the band-shaped body 21 is pulled in the direction of the outer side P2 to eliminate the slack of the band-shaped body 21 and bring the band-shaped body 21 and the back support portion 1 for the Hondanden reinforced belt into close contact with the body.

Next, as shown in FIG. 7B, the end reinforcing tool 25 side of the strip-shaped body 21 is connected to and fixed to the first annular portion 23A and the second annular portion 23B. Specifically, the end reinforcing tool 25 side of the strip-shaped body 21 pulled to the outer side P2 in the first half procedure is folded back to the abdominal side P1 and inserted from the outside of the second ring portion 23B to the inside of the first ring portion 23A. After that, the end reinforcing tool 25 side is further pulled. As a result, the strip 21 is pressed against the first annular portion 23A while covering the second annular portion 23B, and the inner peripheral surface of the first annular portion 23A and the inner peripheral surface and outer circumference of the second annular portion 23B. A frictional force is generated between the surface and its own contact portion (belt-shaped body 21) that is folded back and overlapped, and the tightening force of the strip-shaped body 21 is fixed. If the adhesion between the strip-shaped body 21, the first ring portion 23A, and the second ring portion 23B is relaxed, the frictional force is released and the overall tightening force can be easily finely adjusted.

Furthermore, adjust the mounting position and mounting angle suitable for strengthening Tanda. For example, when pressurizing diagonally from the lower abdomen toward the back, the position of the buckle portion 23 is lowered, and the position of the back rest portion 1 for the Dantian reinforced belt of the present embodiment is further raised. As a result, the band-shaped body 21 can exert a tightening force diagonally upward from the abdominal side to the back side, and the back pad 9 provided on the back pad 1 for the Honda reinforced belt allows the unwilling position. Fluctuations can be suppressed and the tightening position can be maintained.

That is, the position of the backrest portion 1 for the Tanda reinforced belt of the present embodiment can be freely changed up, down, left and right with the Tanda reinforced belt attached, and depending on the positional relationship with the buckle portion 23 located in the abdomen. , The mounting angle and mounting width of the Dantian reinforced belt can be set arbitrarily. Thereby, the wearing angle can be substantially matched with the angle of the line segment connecting the anterior superior iliac spine and the fifth lumbar vertebra.

By the above procedure, the mounting of the Dantian reinforced belt provided with the backrest portion 1 for the Dantian reinforced belt of the present embodiment in the present embodiment is completed. The band-shaped body 21 made of cotton material makes it possible to achieve both flexibility and strength in the Dantian reinforced belt, and it will not be damaged even when high adhesion to the abdomen and clothing pressure are applied. .. Further, as described above, the band-shaped body 21 can be easily deformed according to the positions of the buckle portion 23 and the back support portion 1 for the Hondanden reinforced belt (contact position with the body), so that the anterior superior iliac spine and the spine The area from the line connecting the 5th lumbar vertebra to the auxiliary bone can be surrounded almost completely.

3. 3. Effect of Tanda Reinforcement Belt 1 Next, the effect of the Tanda Reinforcement Belt provided with the back support portion 1 for the Tanda Reinforcement Belt of the present embodiment will be described with reference to FIGS. 8 and 9. FIG. 8 is a cross-sectional view showing a side view of the trunk subjected to pressurization by the Dantian reinforced belt, and FIG. 9 is a cross-sectional view showing a side view of the trunk repelled by the pressurization by the Dantian reinforced belt.

As shown in FIG. 8, the Tanda reinforced belt provided with the back support portion 1 for the Tanda reinforced belt of the present embodiment is attached at an appropriate mounting position (connecting the anterior superior iliac spine and the fifth lumbar vertebrae) according to the wearer's body shape. By adjusting the position that completely covers the area from the line segment to the auxiliary bone) and the appropriate mounting angle (the angle of the line segment connecting the anterior superior iliac spine and the 5th lumbar vertebrae), the anterior superior iliac spine and the 5th Securely surround and wear the area from the line connecting the lumbar spine to the auxiliary bone. As a result, the abdomen is pressed and the rectus abdominis muscle is pressed from the outside to the body side.

By performing physical exercise in this state, as shown in FIG. 9, the rectus abdominis muscle pressurized from the outside to the body side resists the pressure, and a repulsive force is generated to push it outward from the body side. However, the expansion of the abdomen due to the repulsive force is suppressed by the Dantian reinforced belt, and the repulsive force acts on the body side, so that the clothing pressure increases. As a result, the intervertebral disc is stretched, the lumbar spine spacing becomes appropriate due to the stretching effect, the back pain is relieved extremely effectively, and the psoas major and psoas minor muscles are strengthened to improve abdominal slack and stoop, and exercise. The function can be suitably restored or improved.

Although the typical embodiments of the present invention have been described above, the present invention is not limited to these, and various design changes are possible, and all of these design changes are included in the technical scope of the present invention. Is done.
