Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pelvis adjuster used for adjusting a human pelvis.
[0002]
[Prior art]
FIG. 4 shows the curved state of the lumbar vertebra, and the circled portion is the lumbar vertebra. As shown in FIG. 4A, the state where the lumbar vertebra is anterior bay is normal, and the state where the pelvis (iliac and sacrum) is also tilted forward is normal. These inclinations of the pelvis and lumbar vertebra are determined from the balance between the rectus femoris muscle that tilts the pelvis forward and the iliopsoas muscle that tilts the pelvis and lumbar vertebrae forward, and the rectus abdominis muscle that tilts the pelvis backward.
[0003]
[Problems to be solved by the invention]
However, while modern people have fewer opportunities to walk and the rectus femoris and iliopsoas muscles are weak, they are forced to lean forward by deskwork or driving the car, so the rectus abdominis Is getting stronger. For this reason, anterior bay loss of the lumbar spine (see FIG. 4B) or a posterior bay has occurred, or posterior displacement of the pelvis has occurred. This unnatural state of the lumbar spine and pelvis causes back pain.
[0004]
In order to adjust such an unnatural state of the pelvis, there are various treatment methods. However, it is necessary to have a specialist perform treatment, and there is a problem that costs and time are required.
[0005]
An object of this invention is to provide the pelvis adjuster which can perform pelvis adjustment easily in view of the said point.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, the upper body support portion (10) having at least an area where the user can lay the upper body in a supine position and the crotch as a contact point by straddling the user. A pelvis support unit (20) capable of placing a pelvis, and when the user lies on the pelvis support unit in a state where the user sits over the pelvis support unit and pelvis is placed on the pelvis support unit. In addition, the user's foot can naturally hang down.
[0007]
With such a configuration, the rectus femoris muscle and the iliopsoas muscle are pulled by the weight of the user's foot, so that the pelvis and lumbar vertebra are pulled forward. At this time, since the pelvis is placed on the pelvis support part (20) with the pelvis support part (20) straddled, the pelvis and the lumbar spine are effectively pulled forward with the crotch as a fulcrum. As a result, the pelvic anteversion and the lumbar anterior bay can be efficiently recovered. As described above, the pelvis can be adjusted by using the weight of the user's own foot simply by lying on the upper body support portion (10) over the pelvis support portion (20). Adjustments can be made.
[0008]
Specifically, as in the invention described in claim 2, the upper body support portion has a substantially rectangular horizontal surface, and the pelvis support portion has an elongated shape having a width that can be spanned by the user. The upper body support part and the upper surface are arranged in the horizontal direction so that they are at the same height, and the one end side of the pelvic tone support part is parallel to the longitudinal direction in the vicinity of the center of one end side of the upper body support part. It can be assumed that it is connected.
[0009]
Further, as in the third aspect of the invention, the upper body support portion has a shoulder width direction length (B) of a portion corresponding to the shoulder when the user lays the upper body in the supine direction in the user's shoulder width direction. It is characterized by being set to a length excluding the shoulder.
[0010]
With such a configuration, when lying on the back on the upper body support portion, the arm can be hung down, and the pectoralis major and small pectoral muscles are pulled by the weight of the arm. As a result, these muscles can be stretched, and good results can be obtained for periarthritis or the like in which the shoulder joint hurts.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2 show the configuration of the pelvis adjuster of the present embodiment. 1 (a) is a plan view, FIG. 1 (b) is a front view, FIG. 2 (a) is a left side view of FIG. 1 (b), and FIG. 2 (b) is a right side view of FIG. 1 (b). FIG.
[0012]
As shown to Fig.1 (a), the pelvis adjuster of this embodiment is comprised from the upper body support part 10 which mounts a human upper body, and the pelvis support part 20 which mounts a pelvis. In the present embodiment, the upper body support portion 10 is formed in a substantially rectangular shape corresponding to the upper body of a human, and the pelvis support portion 20 has a substantially rectangular shape whose shorter side length is shorter than that of the upper body support portion 10. It is formed in an elongated shape. One end side of the pelvis support portion 20 is connected to the vicinity of the center of one end side of the upper body support portion 10. The pelvis adjuster straddles the pelvis support 20 with the user facing away from the upper body support 10, and is placed on the upper body support 10 with the pelvis placed on the pelvis support 20 with the crotch as a contact point. Use with your upper body lying on your back.
[0013]
The upper body support portion 10 only needs to have an area where the upper body above the waist can be placed. The length in the longitudinal direction (long side) A, which is the length in the height direction of the upper body support part 10 suffices to be equal to or greater than the sitting height of the user. ) B may be a length that is slightly narrower than the shoulder width of the user. Specifically, the length B in the lateral direction of the upper body support portion 10 may be equal to or greater than the width excluding the shoulder in the user's shoulder width direction. The upper body support part 10 of the present embodiment has a longitudinal length A of 80 cm and a lateral length B of 45 cm.
[0014]
The pelvis support part 20 should just be able to carry a pelvis by making the crotch straddle with both legs as a contact point. The length C in the longitudinal direction of the pelvis support portion 20 may be equal to or longer than the length that allows the user's pelvis to be stably placed, and the length D in the lateral direction may be a width that allows the user to straddle. If the length D in the short direction of the pelvic support part 20 is too narrow, the weight is concentrated on a part of the crotch, and if it is too wide, it becomes unstable, so that the pelvis can be stably placed. Select the dimensions as appropriate. In the pelvis support portion 20 of the present embodiment, the length C in the longitudinal direction is 40 cm, and the length D in the short direction perpendicular to the longitudinal direction is 7 cm.
[0015]
Moreover, as shown in FIG.1 (b), the upper surface of the upper body support part 10 and the pelvis support part 20 is the same height, and forms the same surface. These heights H are such that the user's feet lightly touch the floor surface while the user is lying on the upper body support portion 10 and the feet are naturally hung downward, or the user's feet are on the floor. Set it away from the surface. It is desirable to set the height H so that the user's foot is away from the floor surface in terms of the stretching effect of the rectus femoris and the iliopsoas muscle. The upper body support portion 10 and the pelvis support portion 20 of the present embodiment have a height H of 80 cm.
[0016]
In addition, each dimension of the said upper body support part 10 and the pelvis support part 20 is a numerical value which can be selected arbitrarily according to a user's physique.
[0017]
As shown in FIGS. 1B and 2A, the upper body support unit 10 includes a frame unit 11 constituting a skeleton, four leg units 12 connected below the frame unit 11, and a frame unit 11. And a mat portion 13 provided on the upper portion of the head. For example, a metal pipe member can be used for the frame portion 11 and the leg portion 12 in order to ensure rigidity. The mat portion 13 that directly touches the user's body can be made of an elastic material such as urethane in order to ensure comfort.
[0018]
As shown in FIG. 1B and FIG. 2B, the pelvis support portion 20 includes a frame portion 21, a leg portion 22, and a mat portion 23, similarly to the upper body support portion 10. One end side of the frame portion 21 of the pelvis support portion 20 is detachably fixed to the vicinity of the center of one end side of the frame portion 11 of the upper body support portion 10 with a screw. A leg portion 22 is connected to the other end side of the frame portion 21 of the pelvis support portion 20 below. As shown in FIG.2 (b), the leg part 22 of the pelvis support part 20 is comprised by the wide lower end part, and is aiming at stabilization. For example, a metal pipe member can be used for the frame portion 21 and the leg portion 22 to ensure rigidity, and an elastic material such as urethane can be used for the mat portion 23 to ensure comfort. .
[0019]
Next, the usage method of the pelvis adjuster of this embodiment is demonstrated with reference to FIG. First, the user straddles the pelvis support portion 20 with the back facing the upper body support portion 10. Then, the user warps the upper body backward while the pelvis is placed on the pelvic support unit 20 and lies on the back on the upper body support unit 10. At this time, both feet are naturally hung downward from the pelvic support 20. This posture is held for about 10 to 15 seconds at a time. Thereby, as shown in FIG. 3, both feet are pulled downward by the own weight with the crotch as a fulcrum.
[0020]
At this time, the quadriceps muscle, including the rectus femoris muscle, the iliopsoas muscle, the sewing muscle, the thigh fascia latae muscle, the adductor muscle, the pubic muscle, and the thin muscle are pulled. it can. Of these, the pelvis and lumbar vertebrae are pulled forward by pulling the rectus femoris and iliopsoas muscles. At this time, since the pelvis is placed on the pelvis support 20 with the pelvis support 20 straddled, the pelvis and the lumbar vertebra are effectively pulled forward with the crotch as a fulcrum. As a result, the pelvic anteversion and the lumbar anterior bay can be efficiently recovered. This improves various symptoms due to chronic low back pain, tight back and posterior displacement of the iliac bone.
[0021]
As described above, according to the pelvis adjuster of the present embodiment, the pelvis adjustment is performed using the weight of the user's own foot only by lying on the back of the upper body support unit 10 across the pelvis support unit 20. And pelvic adjustment can be easily performed. Further, according to the pelvis adjuster of the present embodiment, since the stretch is performed using the weight of the user's own foot, it is not a sudden stretch, and the lumbar anterior bay can be safely and comfortably made. Can be made. The pelvis adjustment by the pelvis adjuster may be repeated about three times a day.
[0022]
When the length B in the shoulder width direction of the upper body support portion 10 is set to a width excluding the shoulder in the user's shoulder width direction, the user can lie on his back on the upper body support portion 10 as shown in FIG. When it becomes, the arm can be hung down from the upper body support part 10. Thereby, the arm is pulled downward by its own weight. At this time, the large pectoral muscle and the small pectoral muscle are pulled, so that these muscles can be stretched. This can provide an additional effect of giving good results to periarthritis (so-called fifty shoulders) in which the shoulder joint hurts.
