Description

  The present invention relates to a pelvic correction belt for correcting pelvic distortion.

In general, the majority of modern people have a weak muscular weakness due to lack of exercise and a lifestyle with many bad postures, and the pelvis opens and tilts backwards, resulting in various chronic illnesses, including low back pain. It is pointed out. By the way, as a belt for correcting the pelvis, the pelvis correction belt previously disclosed by the present inventor, that is, an upper belt piece made of elastic cloth and mainly covering the iliac crest and sacroiliac joint, has the same elasticity. And a lower belt piece mainly covering the hip joint, and both ends of the upper and lower belt pieces are coupled to each other in a superposed state, and the intermediate portion is coupled to each other by a plurality of elastic fabric coupling pieces. In addition, there is known a pelvic correction belt having a basic configuration in which both end coupling portions of the upper and lower belt pieces are detachably connected via an engaging member (see Patent Document 1 and Patent Document 2). ). In the conventional example configured as described above, the upper and lower belt pieces are applied to the iliac crest, sacroiliac joint, and hip joint portions of the human body, and the joints between the both ends of the upper and lower belt pieces are appropriately attached by the engaging members. It is attached by connecting with the tightening force of, and the pelvis is always stabilized in the correct position and corrected.

  However, the above conventional example supports the iliac crest, sacroiliac joint, and hip joint part of the human body with only two upper and lower belt pieces, and corrects the pelvis tilted by the elasticity of each belt. Although it is going to return to the position, the skin under the belt is subjected to a large pressing force by this elastic force, which causes a blood flow obstruction such as a capillary under the skin. In addition, due to the tightening of each belt due to the elastic force, the movements necessary for daily life such as standing and sitting were excessively restrained. And there existed a problem that it might become difficult to continue wearing habitually by the discomfort.

  Furthermore, in order to relieve the feeling of pressure given to the wearer, there is a problem that the belt becomes torn by repeating the wearing and washing because the strength is weakened by providing a notch in a part of the belt.

  Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a pelvic correction belt according to the present embodiment. FIG. 3 shows the distribution in the width direction of the linear density of elastic fibers provided in the longitudinal direction in the upper belt and the lower belt constituting the pelvic correction belt according to the present embodiment.

  1 and 2, 1 is a pelvic correction belt, 2 is an upper belt piece constituting the pelvis correction belt 1, and the upper belt piece 2 is composed of a thick elastic band having stretchability and elasticity in the longitudinal direction, It is wide and covers the iliac crest and sacroiliac joint. Reference numeral 3 denotes a lower belt piece which is joined to both ends of the upper belt piece 2 in a superposed state, and the lower belt piece 3 is formed of a thick elastic band having stretchability and elasticity in the longitudinal direction. It has the width and length to cover Reference numeral 4 denotes a first connecting portion formed by joining one end of the upper belt piece 2 and one end of the lower belt piece 3 in a superposed state, and 5 denotes the other end of the upper belt piece 2 and the other end of the lower belt piece 3. It is the 2nd connection part comprised by couple | bonding with in a superposition | polymerization state. The first connecting part 4 and the second connecting part 5 are provided with a male hook hook 4a and a female hook hook 5a for connecting to each other. 6 and 6 are made of elastic fabric, and are a pair of connecting pieces on both sides for connecting intermediate portions of the upper belt piece 2 and the lower belt piece 3 at a predetermined interval, and 7, 8 and 9 are body shapes when worn. Center darts 10 formed on the upper edge of the central portion of the upper belt piece 2 and the upper and lower edges of the central portion of the lower belt piece 3 so as to fit are pocket portions formed inside the central portion of the upper belt piece 2. , 11 is a support block accommodated in the pocket portion 10. Reference numerals 12 and 12 are notches formed at both ends of the lower belt piece 3, respectively, so as to cover the notch 12, the cushioning cloth 13 that can expand and contract in both the longitudinal direction and the width direction and has elasticity. , 13 are attached. The relaxing cloth 13 is configured to be thinner than the lower belt piece 3. In the lower belt 3, narrow portions 3 c and 3 c exist between the notch 12 and the lower edge 3 b of the lower belt 3.

  Reference numerals 14 and 14 denote a pair of thigh attachment members on both sides respectively connected to both ends of the lower belt piece 3 so as to prevent the pelvic correction belt 1 from rising when worn, and the thigh attachment member 14 is substantially short. The upper edge 14a in the width direction is sewn in a suspended manner on the lower belt piece 3, and the end portion 14b and the end portion 14c are the anchoring protrusion 15 and the loop-shaped fiber yarn 16 while being formed in a band shape. The hook-and-loop fastener can be attached freely by a hook-and-loop fastener constructed from the above.

  Next, elastic bands constituting the upper belt 2 and the lower belt 3 will be described with reference to FIG. The elastic band 17 has elasticity and elasticity in the longitudinal direction by knitting elastic fibers in the longitudinal direction. In the prior art, the stretchable cloth used for the pelvic correction belt has a uniform distribution in the longitudinal direction in the longitudinal direction.

  The pelvic correction belt is once stretched from a natural state and then attached, and the pelvis is corrected by tightening the waist. Therefore, the required elasticity and rigidity of the pelvic correction belt are very large. When using a pelvic correction belt that has a uniform stiffness distribution in the width direction, it will also act on local movements such as warping the upper body, so restrain the movement of the body. become. Moreover, blood flow obstruction may be caused by always tightening the same place during wearing. To correct the position of the pelvis to the correct position, it is important to continue to wear the pelvic correction belt. However, wearing it restricts daily movements such as standing and sitting and causes blood flow obstruction. , Discomfort and psychological burden on wearing become large, and it becomes a factor that hinders continuous wearing.

  Therefore, in the pelvic correction belt 1 according to the present invention, the rigidity distribution of the elastic band 17 constituting the upper belt piece 2 and the lower belt piece 3 is not uniform in the width direction, but is changed along the width direction. As a result, it is possible to weaken the restraint on local movement while securing the elastic force necessary for pelvic correction as the entire pelvic correction belt 1. The rigidity of the elastic band 17 is substantially proportional to the linear density of the elastic fibers extending in the longitudinal direction (thread thickness = generally expressed in denier units), as shown in FIG. By changing the width along the width direction, a desired rigidity distribution can be realized.

  It is possible to expand and contract in the longitudinal direction by weaving multiple elastic fibers extending in the longitudinal direction of the elastic band according to the desired rigidity into a single warp and weaving this with the weft extending in the width direction of the elastic band An elastic band having elasticity can be formed. At this time, by setting the number of elastic fibers included in one unit of warp according to the position in the width direction, it is possible to realize an elastic band in which the linear density of the elastic fibers changes along the width direction. it can. That is, by changing the linear density of the elastic fiber contained in each warp located in a certain region in the width direction, the stiffness distribution along the width direction can be made stepwise, and at the same time, the elastic band Manufacturing is easy. Further, by using a normal fiber having no elasticity as the weft, it is possible to configure an elastic band that can be stretched and contracted only in the longitudinal direction and has no elasticity in the width direction. The weaving method of the elastic band is not limited to plain weave, and twill weave or satin weave can be applied.

  The linear density distribution of the elastic fibers contained in the elastic band 17 is shown in FIG. 3 in FIG. 3 is a linear density distribution shape of the elastic fiber in the present embodiment in which the width of the elastic band 17 is 160 mm. As shown in the figure, the linear density distribution 18 of the elastic fiber has a step-like distribution shape along the width direction, the line density at both ends in the width direction is the smallest at 280 denier, and in the substantially central portion in the width direction. The linear density is maximum at 840 denier. In this case, while maintaining the elastic force of the entire belt piece acting to return the pelvis to the original position, the elastic force at the center in the width direction is large and the elastic force at the end in the width direction is small. For this reason, the restraining force against local movement such that only the end portion in the width direction of the belt expands and contracts is smaller than the restraining force in the case where the linear density distribution of the elastic fibers is uniform in the width direction. Accordingly, it is possible to prevent the wearer's movement from being excessively restrained and to give the wearer discomfort and a psychological burden.

  Further, in the linear density distribution shape 18 of the elastic fiber in the present embodiment, as shown in FIG. 3, the maximum areas 18a and 18a having a linear density of 840 denier sandwich the minimum area 18b having a linear density of 560 denier. Two places are provided. If a plurality of locations having a rigidity peak are provided in this way, the body part to which the maximum tightening force is applied differs depending on the posture taken by the wearer, so there is a risk that only one place is always tightened and blood flow is hindered. Every time it moves, it can promote blood flow. In the present embodiment, the maximum areas 18a, 18a of the elastic fiber linear density are provided in two places, but it is also possible to provide three or more places. Furthermore, in the present embodiment, the local maximum regions 18a and 18a have the same maximum value (840 denier), but the linear density distribution shape 18 of the elastic fiber can be configured so as to have different maximum values. is there.

  In the present embodiment, as the material of the elastic band 17 constituting the upper belt piece 2 and the lower belt piece 3, polyurethane is used for the elastic fiber, and the other fibers are excellent in water absorption, diffusibility and quick drying property. Acrylic fiber and polyester fiber are used. When worn directly on the bare skin, these properties of water absorption, diffusibility and quick drying are effective.

  Next, the notch 12 provided in the lower belt piece 3 and the relaxation cloth 13 attached so as to cover the notch 12 will be described.

  The pelvic correction belt 1 is attached so that the lower belt piece 3 covers the groin on the front surface of the body. The groin part has a large expansion and contraction width when shifting from the standing position to the sitting position. Compresses the groin area to cause discomfort to the wearer.

  Therefore, in the conventional pelvic correction belt, a notch 12 is provided at a position facing the inguinal portion of the lower belt, and the notch 12 relieves the feeling of pressure on the inguinal portion. However, if the position facing the inguinal portion is notched, the narrow portion 3c remains between the notch 12 and the lower edge 3b of the lower belt 3. As the process repeats, the narrow part 3c shifts downward from the thigh, resulting in a problem that it deviates from the optimum position of the pelvic correction belt. Further, the notch 12 causes stress concentration, and a large load is locally applied during washing and the possibility that the narrow portion 3c is torn is increased.

  Therefore, when the relief cloth 13 is constructed by attaching a thin elastic cloth that can be expanded and contracted in both the longitudinal direction and the width direction of the lower belt piece 3 so as to cover the notch 12, the narrow portion Since moderate tension is always applied upward with respect to 3c, even if standing and sitting are repeated, there is no possibility of shifting downward. Further, stress concentration is alleviated and a large load is not locally applied to the narrow portion 3c, so that there is no possibility of tearing from the portion. As the material of the relaxation cloth 13, a thin elastic cloth having a high degree of elasticity that is difficult to cause wrinkles, specifically, a power net material is preferably used.

  Next, the support block 11 provided in the upper belt piece 2 will be described. The upper belt piece 2 is provided with a center dart 7 on the upper side in the width direction so as to fit the body shape, but in the vicinity of the center dart 7 there is a region that floats from the body when worn, and the width direction of the upper belt piece 2 Only the edges may touch the body and cause local compression. Therefore, by providing the support block 11 made of a soft material in the vicinity of the center dart 7, the space generated for the center dart 7 can be filled, and local pressure is prevented and comfortable wearing is realized. be able to. At the same time, the support block 11 has an important role of adjusting the displacement of the sacroiliac joint. A soft material such as silicon is preferably used for the support block 11. The size, thickness, and elasticity of the support block 11 can be appropriately selected according to the wearer's body shape. Further, since the support block 11 is accommodated in the pocket portion 10 provided in the upper belt piece 2, it can be easily attached and detached, and can be exchanged according to changes in the body shape and the like. Furthermore, it is also possible to apply an analgesic / anti-inflammatory agent or a percutaneous absorption-type drug to the surface of the support block 11, thereby providing an analgesic / anti-inflammatory action and a drug effect to the wearer.

  Next, a method of using the pelvic correction belt 1a according to the present invention will be described with reference to FIGS. FIG. 4 shows a perspective view when the pelvic correction belt 1 is attached to the human body M, FIG. 5 shows a side perspective view seen from the side of the human body M, and FIG. 6 shows a rear perspective view seen from the back of the human body M. Shown in First, the upper belt piece 2 and the upper belt piece 3 are respectively applied to the iliac bones 21 and 21 and the sacroiliac joints 22 and 22 and the hip joints 23 and 23 of the human body M (see FIG. 6), and the pelvic correction belt 1 After the first connecting portion 4 and the second connecting portion 5 of the human body M are connected to each other with an appropriate tightening force by the male hook hook 4a and the female hook hook 5a on the front surface of the human body M, the thigh attachment members 14 on both sides are mounted. , 14 are appropriately wound around the outer circumference according to the size of the thighs 28, 28, and the hook-like projection 15 provided on the end 14b and the loop-shaped fiber yarn 16 provided on the end 14c, Is engaged (see FIG. 4). At this time, it is preferable that the lower belt piece 3 is pulled to the left and right so that about one third of the lower belt piece 3 is applied to the foot from the boundary between the hip and the foot of the human body M, and is turned forward and hooked (see FIG. 5). And in front of the human body M, it stops at the position of moderate strength, and the 1st connection part 4 and the 2nd connection part 5 of the pelvis correction belt 1 are set on a pubic bone (not shown). Thus, the upper belt piece 2 pushes up the iliacs 21 and 21 from the back to the front and supports the sacrum 24. Further, the displacement of the sacroiliac joints 22 and 22 and the pubic joint 27 is adjusted. Further, the lower belt piece 3 pushes up the hip joints 23 and 23 which are the contact points of the femurs 25 and 25 receiving the whole weight and the pelvis 20 from the rear to the front (see FIG. 5). Note that the support block 11 inside the central portion of the upper belt piece 2 is positioned just behind the sacrum 24 by mounting the pelvic correction belt 1 (see FIG. 5).

  At this time, since the thigh attachment member 14 sewn in a suspended manner on the lower belt piece 3 is attached to the thigh, the pelvic correction belt 1 is slipped even during standing and other operations during wearing. The ascending can be reliably prevented and the pelvis can always be stably corrected in the correct position. When it is necessary to release the pelvic correction belt 1 from the thigh 28 at the time of stool, etc., the anchoring protrusion 15 and the looped fiber yarn 16 are disengaged and the thigh is attached. The member 14 may be in a free state.

  In the above-described embodiment, the end portion 14b and the end portion 14c of the thigh attachment member 14 are engaged by a hook-and-loop fastener composed of the fastening protrusion 15 and the loop-shaped fiber yarn 16. However, the present invention is not limited to this, and a known engaging member such as a snap button can be adopted and used.
