Description

The present invention relates to a pelvic correction supporter that can correct posture, and to a method for wearing the supporter, which uses the anterior superior iliac spine, a bone that protrudes from the lower back, to strongly pull the pelvis toward the back and correct posture.

Corrective tightening belts such as lumbar supporters are used by people who have concerns about their lower back, etc. The applicant of the present application has already provided a lumbar supporter (Patent Document 1) that aims to provide a corrective tightening belt that reduces the tightening force on the abdomen and provides a comfortable fit.
On the other hand, the term pelvic correction is known as a method to correct pelvic distortion. Pelvic distortion refers to the pelvis being tilted to the left or right or forward or backward, and it is said that pelvic distortion has a negative effect on bodily functions and can also cause lower back pain. The functions of the pelvis are: it supports the skull from the spine and supports the upper body; it is connected to the hip joint and helps the hip joint when walking; it supports the body as a fulcrum when sitting on a chair or the floor; it acts as a receptacle because the internal organs are contained within the pelvis; and it is the place where the uterus that contains the fetus is placed when a woman is pregnant.

Patent Document 1 describes a device that includes a belt-like belt (11) that is wrapped around a person's waist and abdomen, a waist support member (13) that is provided on the inner center of the belt and that is brought into contact with the person's lumbar spine, a pair of side support members (12) that are provided on both sides of the belt and that are brought into contact with the pair of iliac bones on the left and right sides of the person's waist, and auxiliary belts (17, 18) that are provided under the center of the belt and that cover the hip joints from above the buttocks and are wound around the hip joints with both ends connected to each other at the lower abdomen, and the waist support member and the side support member are made of soft resin, hard rubber, foamed resin, or three-dimensional structured fabric, and have bending hardness, thickness, and other properties that are not crushed by the tightening force of the belt. The orthopedic tightening belt is characterized in that the side support member is made of a material having elasticity and shock absorption, the side support member is provided to be freely position-adjustable with respect to the lumbar support member, the side support member has a recess formed in the center, the periphery of the recess abuts the iliac part so as to surround the iliac spine, the thickness of the pair of side support members forms a space between the inner surface of the belt and the abdominal surface between the pair of side support members, and the belt, the lumbar support member, and at least one of the inner sides of the side support member has a non-slip part formed thereon. The effect of the belt is described as follows: "(0016) In addition, the side support members that abut the left and right iliac parts are provided to be freely position-adjustable, and the abutment position is adjusted to be positioned on the abdominal side, thereby further reducing the sense of pressure. In particular, by forming a recess in the center of the side support member, the recess abuts the iliac spine so as to surround it, preventing the support member from being displaced and reducing extreme stress concentration on the iliac spine."
Patent Document 2 discloses the following: "(Claims) (Claim 1) The present invention is a detachable waist belt that covers from the sacroiliac joint to the abdomen, and is a pelvic adjustment brace composed of an outer basic belt 1 with fastening means at both ends, and an inner adjustment belt 2 sewn to the basic belt at the center of the back. It has a function of adjusting (treating) functional disorders (lack of physiological compatibility and mobility) of intracapsular movement of the sacroiliac joint, which is one of the causes of non-specific back pain (back pain whose cause cannot be identified through diagnostic imaging, accounting for 85% of all back pain). (Claim 2) The basic belt 1 is made of a stretchable material and has through holes 3 on both sides. The center of the back side of the adjustment belt 2 is made of a material with a higher stretch rate than the basic belt 1, and both ends are exposed to the outside through the through holes 3 of the basic belt 1 and are fastened to the surface of the basic belt 1 by hook-and-loop fasteners 4."
Patent Document 3 discloses that "the intracapsular correcting device 100 includes a first corset 10 surrounding the sacrum and ilium, a second corset 20, a third corset 30, and a bag portion 50 provided in the first corset for storing a pressing body P formed of a hollow spherical body that elastically deforms when pressed against the sacroiliac joint. The bag portion 50 is elastic and formed of a member that holds the pressing body therebetween, and is formed in pair to store the pressing body P side by side. When the pressing body P stored in the bag portion 50 presses against the sacroiliac joint, the pressing body P is supported in a recess formed by the sacrum and the posterior superior iliac spine."

Patent No. 4840881 JP 2018-7999 A JP 2015-177897 A

In the above Patent Documents 1 to 3, in order to tightly fasten the waist while the waist belt is still being worn, a second fastening belt is provided in addition to the waist belt for further tightening.
However, correcting body posture generally requires a force stronger than that of a waist belt, and in particular, to change the tightening direction (for example, to apply a force in the opposite direction to the tightening direction of the first belt), a considerably strong force is required in that direction, but the above-mentioned Patent Documents 1 to 3 were not able to exert such a strong force. This will be explained below using pelvic correction as an example.
Pelvic corrections include methods that simply push and pull the pelvis, methods that twist the lower back, methods that do not directly stimulate the pelvis but approach the joint capsule that surrounds the sacroiliac joint, which is a part of the pelvis, to remove the cause of pain from the sacroiliac joint, and methods that apply shear force (vertical force) to the sacroiliac joint.The pelvis is made up of three bones called the ilium, ischium, and pubis, which come together to form the hipbone (see Figure 11), and there is also a bone called the sacrum, and the hipbone and sacrum together are called the pelvis.
However, all of the above-mentioned devices are used to tighten the lower back, and are not sufficient for correcting posture (straightening the back), and either the tightening direction is only one-way or it is not possible to apply a strong corrective force in a direction different from the tightening direction (for example, the opposite direction).
In the above-mentioned Patent Documents 1 and 2, the tightening direction of the outer pulling member is opposite to that of the present invention, whereas in the above-mentioned Patent Document 3, the tightening directions of the base belt 1 and the adjustment belt 2 are the same.

In addition, in a patent application dated March 29, 2019 (Application No. 2019-67919), the applicant provides a corrective tightening belt and tightening method that can correct posture, such as pelvic correction, by aligning with the location of bones that protrude from the body, exerting the force required for strong physical correction, and obtaining a large force even when pulling in a direction different from the tightening of the belt. The invention related to this application can correct the pelvis with a stronger force than a normal lower back pain belt.
However, it would be ideal if the strong force required for pelvic adjustment could be achieved with a simple operation similar to that of a normal back pain belt, by ingenuity in the operation.
Therefore, the object of the present invention is to provide a correction supporter and a method for wearing the same which are the contents of the above patent application, but which are further developed to focus on pelvic correction, and which are configured to be aligned with the left and right anterior superior iliac spines to exert the strong force required for pelvic correction, and which are ergonomically designed to easily obtain the force required for correction when worn.

The pelvis correction supporter of the present invention is a belt-like belt that is wound around the pelvis and has both ends fastened to each other on the abdominal side (front side), a pair of bone fastening pads that are arranged on the inside of the belt-like belt and are hooked onto the anterior superior iliac spine, and a pair of tension adjustment bands that are pulled toward the abdominal side (front side) with their base ends at the position of the bone fastening pads.
This is a pelvic correction supporter characterized by aligning the bone-locking pad with the position of the anterior superior iliac spine, wrapping the belt around the pelvis, and then adjusting the position of the bone-locking pad with the tension adjustment band.
According to the present invention, the belt is wound around the pelvis and then the position of the bone-locking pad is adjusted by the tension adjustment band to exert a corrective force, resulting in a pelvic supporter that is less likely to be worn incorrectly or misaligned. That is, the belt and the pair of bone-locking pads can be adjusted on the stomach side, making it easy to operate and providing a strong adjustment force. According to the present invention, due to the structure of the body, when the wearer pulls the tension adjustment band, it is easier to operate and the pulling force is stronger when pulling from the back side (back side) of the body to the front side (stomach side) than when pulling from the front side (stomach side) of the body to the back side (back side), so that wearing and exerting a corrective force are smoother.

The present invention relates to a pelvic correction supporter as described in claim 1, characterized in that the pair of tension adjustment bands have gripping portions equipped with hook-and-loop fasteners that engage with the hook-and-loop fastener of a belt-shaped belt after being pulled toward the abdomen (front side), and the gripping portions are provided on the abdomen (front side) with the position of the bone-locking pad as a base end to be grasped and pulled by hand.
According to the present invention, the pair of tension adjustment bands can be pulled toward the stomach (front side) and then the gripping portions can be fastened to the belt by hook and loop fasteners, making operation easy.

In this invention, the pair of tension adjustment bands are configured to cross on the back side (rear side) and be pulled, one end of which is sewn across the width of the belt corresponding to the position of the bone-engaging pad, and the other end of which serves as a gripping part that is grasped and operated by hand, and which are a pair of left and right bands that are pulled via the belt, and which are overlapped together to form a single body, and the gripping parts are grasped with the left and right hands and pulled respectively.
According to the present invention, the pair of tension adjustment bands are crossed on the back side (back side) and pulled, so a strong pulling force can be obtained. Also, on the stomach side (front side), the pair of left and right ones are overlapped to form one unit, and the gripping parts are grasped with the left and right hands and pulled, so operation is easy.
In addition, the present invention is characterized in that the pair of tension adjustment bands are configured to cross on the back side (rear side) and be pulled, one end of which is sewn across the width of the belt corresponding to the position of the bone-fastening pad, and a pair of left and right bands that pull in the direction opposite to the direction in which it is desired to bias the position of the bone-fastening pad connected via the belt, and the pair of left and right bands are each pulled by grasping the gripping portions with the left and right hands, and then each is fastened to the belt by a hook-and-loop fastener.
According to the present invention, the force of pulling the tension adjustment band can be evenly transmitted to the bone fastening pad, and the bone fastening pad can be moved and biased in a substantially horizontal direction without being displaced in the vertical direction.

In the present invention, the bone-locking pad is configured by arranging multiple approximately crescent-shaped bone-locking pads at predetermined intervals along the longitudinal direction of the belt, the pads forming protrusions for hooking onto the anterior superior iliac spine, and the protrusions of the approximately crescent-shaped bone-locking pads are arranged toward the adjacent end of the belt.
According to the present invention, the bone-locking pad has an approximately crescent shape that makes it easy to hook onto the anterior superior iliac spine, and by arranging multiple approximately crescent shapes along the longitudinal direction of the belt, it is possible to accommodate differences in the size of the pelvis area due to body type and gender.In addition, even if the bone-locking pad that was originally hooked onto the anterior superior iliac spine shifts toward the back due to over-pulling the tension adjustment band, the adjacent bone-locking pad can be used, so there is no need to re-wrap the belt.

According to the present invention, in order to apply force to the bone-locking pad hooked on the anterior superior iliac spine via the rear side (back side), the wearer can easily exert the strong force required for posture correction (pelvic correction) by aligning the bone-locking pad with the anterior superior iliac spine and tightening the belt around the body, and then pulling the grip of the tension adjustment band from the rear side (back side) to the front side (stomach side).

The following describes an embodiment of the present invention with reference to the drawings.

First Embodiment
As shown in Figures 1 to 5, the pelvis correction supporter 100 of this embodiment is composed of a belt 2 wrapped around the pelvis, a pair of bone locking pads 3 arranged on the inside (the side that contacts the person's waist) of the belt 2, and a tension adjustment band 4 arranged on the outside (surface side) of the belt 2. As shown in Figure 10, this pelvis correction supporter 100 is applied to a position corresponding to the iliac spine (anterior superior iliac spine) Ta of the ilium T of the pelvis, and after the bone locking pad 3 is aligned with the position of the anterior superior iliac spine and the belt 2 is wrapped around the pelvis, the position of the bone locking pad 3 is adjusted by the tension adjustment band 4.

(Regarding the belt according to the first embodiment)
The belt 2 of this embodiment shown in FIG. 3 is shaped to be wrapped around the waist and is made of a mesh material that is stretchable, breathable, and can withstand long periods of wear, but there are no restrictions as long as it is made of a material that is generally used as a supporter.
Furthermore, the belt 2 is provided with a waist support member R1 and reinforcing members R1, R2 at the portion expected to come into contact with the spine, and is provided with fastening means by male and female hook-and-loop fasteners Bf, Bm at both ends to be wrapped around the pelvis and fixed in place. The waist support member R1 is made of synthetic resin or leather and has ventilation holes. The reinforcing members R1, R2 are leather products, and make it easier for the pair of tension adjustment bands 4 to slide on their surfaces.
Furthermore, since the waist support member R1 is provided, an appropriate tightening force can be obtained even as a belt for preventing lower back pain.

(Regarding the bone anchoring pad according to the first embodiment)
The bone anchoring pad 3 of this embodiment shown in Figure 4 has multiple approximately crescent-shaped protrusions (convex portions) Sa arranged at a predetermined interval along the longitudinal direction of the belt 2, and is arranged in pairs on the inside of the belt 2 so as to correspond to the positions of both anterior superior iliac spines Ta when the belt 2 is wrapped around the waist.
The above-mentioned generally crescent-shaped convex portion Sa is directed toward the adjacent end portions E, E' of the belt 2 (the symbols E, E' indicate the pulling direction of the belt 2).
Suitable materials for use include EVA, polyurethane, and the like, which have appropriate bending hardness, thickness, and elasticity so that they do not buckle or collapse under the tightening force of the belt 2.
This shape makes it easy for the bone anchoring pad 3 to hook onto the anterior superior iliac spine Ta, and in addition, since multiple protrusions (convex portions) Sa are arranged at a predetermined interval, even if the position is slightly misaligned, the anterior superior iliac spine Ta will hook onto one of the protrusions (convex portions) Sa, so there is no need to readjust the attachment and it is also possible to fine-tune the attachment position.
The bone anchoring pad 3 of this embodiment shown in Fig. 4 is composed of a pad main body 3a and a cloth bag 3b for fixing to the belt 2, and the pad main body 3a is inserted into the cloth bag and sewn. It is also possible to fix only the pad main body 3a to the belt 2 without using the cloth bag 3. The pad main body is made of rubber and has a roughly crescent shape, making it easy to align (hook) the bone anchoring pad 3 to the anterior superior iliac spine Ta. The pair of tension adjustment bands 4 have their base ends sewn to the cloth bag 3b, and the other end is a grip part 4h for pulling by hand. That is, the pair of tension adjustment bands 4 have their base ends sewn to the cloth bag 3b to form a long triangular member, and at the tip side, two sides are overlapped and joined to the belt 2 as a hook-and-loop fastener (Fig. 9).
The crescent-shaped pad body 3a has a plurality of convex portions (projections) 3a1 to 3a3 that are continuous, so that any of the convex portions (projections) 3a1 to 3a3 can be hooked onto the anterior superior iliac spine Ta (FIG. 12(a)). The plurality of convex portions (projections) 3a1 to 3a3 of the crescent-shaped pad body 3a may have different heights in order to gradually increase the probability of hooking onto the anterior superior iliac spine Ta (FIG. 12(b)). A part of the cloth bag 3b is bonded with an adhesive 3s to make the crescent shape continuous, making it easier to hook onto the anterior superior iliac spine Ta.

(Regarding the tension adjustment band according to the first embodiment)
The tension adjustment band 4 of this embodiment shown in Fig. 5 is a pair of elastic bands, one end of which is a fixed part 4s for fixing to a part of the belt 2 corresponding to the bone locking pad 3, and the other end of which is a grip part 4h, and the wearer adjusts the position of each bone locking pad by pulling the grip part 4h. The connecting band 4j connecting the fixed part 4s and the grip part 4h is connected to at least both ends of the fixed part 4s in the longitudinal direction (the lateral direction of the belt-like supporter 2), so that the force pulling the grip part 4h is evenly transmitted to the bone locking pad 3 via the belt-like supporter 2, contributing to smooth position adjustment (pelvic correction).
Furthermore, a male hook-and-loop fastener is provided on the surface of the gripping portion 4h of the tension adjustment band 4 facing the belt 2, and a female hook-and-loop fastener is provided on the front side of the fixing portion 4s, so that the tension adjustment band 4 can be fastened at a desired position together with the female hook-and-loop fastener Bf provided on the front side of the belt 2. The hook-and-loop fastener Bf provided on the belt 2 and the hook-and-loop fastener provided on the front side of the fixing portion 4s constituting the tension adjustment band allow the gripping portion 4h to be fastened more firmly and stably.
Here, the pair of tension adjustment bands 4 in this embodiment each have a Y-shape (see FIG. 5), but they can also be formed into a V-shape (see FIG. 9), which will be described later.

(How to wear)
With the above-described configuration, in the pelvic correction supporter 100 of this embodiment, the wearer first aligns the pair of bone-engaging pads 3 so that they are hooked onto the left and right anterior superior iliac spines Ta, then wraps the belt 2 around the pelvis and fastens it with the hook-and-loop fasteners Bf and Bm.
Next, by pulling the gripping parts 4h of the pair of tension adjustment bands 4 from the back side to the front side of the body, the pair of bone anchoring pads 3 are biased toward the back side opposite to the pulling direction, and exert a force to correct the left and right anterior superior iliac spines Ta toward the back side (FIG. 6). The symbols F and F' indicate the pulling direction of the pair of tension adjustment bands 4.
As described above, the pair of tension adjustment bands 4 are crossed on the back side (back side) and pulled, one end of which is sewn to the belt 2 corresponding to the position of the bone anchoring pad 3, and the other end is made into the gripping parts 4h, 5h that are grasped and operated by hand, so that the gripping parts 4h, 5h can be pulled to adjust the position of the bone anchoring pad 3 on the stomach side (FIG. 9). That is, the pair of tension adjustment bands 4 are configured such that the left and right pairs are overlapped to form one state, and the central gripping part 4h can be used to pull them out to the center of the end positions of each other.
Here, Japanese Patent Application No. 2019-67919 previously submitted by the applicant of the present application is a corrective tightening belt 1 having a belt-like belt 2 wound around the body and an outer pulling member 4 arranged on the outside of the belt-like belt 2, in which the belt-like belt 2 is tightened around the body at a location of a bone T located so as to protrude from the body, and then the outer pulling member 4 is attached so as to hook the outer side of the belt-like belt 2 to the location of the bone T and pull the outer pulling member 4 (pulling direction F), which is pulled a predetermined length and then engaged with the belt-like belt 2. The present invention is different from the present invention in that the pulling direction F of the outer pulling member 4 is opposite and the pulling length is also shorter.

(Second Example)
In the present embodiment, the pelvis correction supporter 200 has the same configurations as the belt 2 and bone anchoring pad 3 in the first embodiment described above, but the configuration of the tension adjustment band 5 is different.
Therefore, the description of the belt 2 and the bone anchoring pad 3 will be omitted, and the tension adjustment band 5 will be described with reference to the drawings (FIG. 7).

(Regarding the tension adjustment band according to the second embodiment)
In the present embodiment shown in Figure 8, the tension adjustment band 5 has one end as a fixed portion 5s for fixing to a portion of the belt 2 corresponding to the bone anchoring pad 3, and the other end as a gripping portion 5h, and is composed of a connecting band 5j connecting the fixed portion 5s and the gripping portion 5h. A ring 5r held by a retaining member 5a is provided closer to the symmetrical axis A of the belt 2 than the fixed portion 5s, and the band 5 is folded back through the ring 5r and pulled toward the end of the belt 2 (E, E') to adjust its position (pelvis correction), and is fastened by a male hook-and-loop fastener Bm provided on the belt 2 side of the gripping portion 5h, and a female hook-and-loop fastener Bf provided on the outer side (surface side) of the belt 2 and the fixed portion 5s that constitutes the tension adjustment band, as in the first embodiment.
As in the first embodiment, the connecting belt 5j is connected to at least both ends of the longitudinal direction of the fixing portion 5s (the transverse direction of the belt 2), so that the force pulling the gripping portion 5h is transmitted evenly to the bone-engaging pad 3 via the belt 2, contributing to smooth position adjustment (pelvic correction).

Third Embodiment
In this embodiment, as shown in Fig. 13(a) and (b), the pair of outer tension adjustment bands 14 and the bone locking pad 3 located on the inside are connected at two points, and are connected to the side that contacts the skin on the inside through the groove 2e formed in the belt 2. Therefore, the pair of outer tension adjustment bands 14 directly pull the upper bone locking pad 3, so that a strong pulling force can be obtained. Then, each of the two bands 14a, 14b cross each other and are pulled to the center of each other. Therefore, even if the pulling force is applied in a direction (opposite direction) F different from the belt (waist belt) 2, a force larger than the tightening force can be applied to correct posture (correction to straighten the back muscles, etc.). In addition, in the pulling member 14 of this embodiment, the hole 14a formed in a circular shape or the like makes it easier to hook onto the protruding bone (iliac spine) Ta.

As described above, the pelvic correction supporter of the present invention is based on ergonomics, in which the wearer pulls the tension adjustment band forward (toward the stomach) to move the bone-engaging pad 3 backward (toward the back) (to strengthen the correction force), and can be modified as appropriate within the scope of the invention's purpose of being configured to easily transmit force, and there are no limitations on the configuration, material, or shape.
