Description

  The present invention relates to a hip joint stabilization wear that is used by being mounted on a hip joint part and stabilizes the activity of the hip joint.

  When the hip joint performs an internal rotation operation (an operation in which the thigh is directed inward), the Z ligament (iliac femoral ligament, pubic femoral ligament) is loosened, and stability is lowered. In addition, the decrease in stability due to the internal rotation of the hip joint tilts the pelvis from the intermediate position, so that the muscle activity behind the hip joint decreases, and the long axis of the lower limbs and the spinal curvature change.

  On the other hand, in order to support and fix the movement of the hip joint, wear such as tights and girdles related to the movement of the hip joint is widely provided. These tights, girdles, etc. have a strong region and a weak region due to the difference in modulus of the material, thereby functioning to support and fix the movement of the hip joint (for example, patents) References 1 and 2).

  In addition, wear that supports the body's motor function by realizing the difference in modulus of the material by the multilayer structure of the material and thereby supports muscle contraction has been proposed (see, for example, Patent Document 3).

JP 2004-238789 A JP 2001-192903 A JP 2008-138322 A

  However, in such wears such as conventional tights and girdles, the movement of the hip joint is restricted by mounting the wear near the hip joint, and the actually displaced hip joint is stabilized. It does not have a function to guide to the place. For this reason, the hip joint becomes unstable, and the hip joint is maintained in a state of internal rotation and flexion, and the long axis of the lower limb is displaced and the pelvis is inclined, resulting in normal spinal curvature due to muscle fatigue. There was a problem that mutations occurred.

  The present invention has been made in order to solve the problems in such wears such as conventional tights and girdles, and the object of the present invention is to provide an internal force generated in the hip joint by receiving an external load or an exercise load. By guiding the rotation / bending movement to the external rotation / extension direction and thereby guiding the hip joint to the intermediate position, the unstable state of the hip joint caused by the internal rotation / bending of the hip joint is reduced and the movement of the hip joint is restricted. It is an object of the present invention to provide a hip joint stabilization wear that can stably operate the hip joint without any problems.

In order to achieve the above object, the hip joint stabilization wear according to the present invention is formed of a stretchable material having a frictional resistance so as not to cause positional displacement with the skin, and at least between the hip and the knee joint from the waist. A lower body wear body having a predetermined size and shape covering up to an intermediate part, and a predetermined part integrally provided in the longitudinal direction of the thigh at a corresponding part of the inner rear surface of the left and right thighs of the lower body wear body One end is connected to the long thigh vertical belt and the upper end of the thigh vertical belt so as to incline gently in an oblique direction, and from the inner surface of the thigh to the corresponding part of the front of the hip joint One end is connected to the lower end of the first thigh towing belt provided and the lower end of the thigh towing belt so as to be greatly inclined in an oblique direction, and further from the thigh inner surface to the front thigh Integrated into the corresponding part A second thigh towing diagonal belt integrated with the other end of the first thigh towing diagonal belt, the first thigh towing oblique belt and the second is the coupling one end portion to the connecting portion of the thigh tow diagonal belts, and elastic belt of a predetermined length which is contactable to cross in the vicinity of the sacrum from the hip outwardly through buttocks, another of the telescopic belt is connected at one end thereof to an end portion, from said near sacrum is a guide capable to abut a portion corresponding to the side and the front waist upper length by a buckle at the waist portion front adjustable to other end And pulling both ends of each traction operation belt through the buckle while tensioning each thigh traction diagonal belt via each telescopic belt Characterized by external rotation and extension of the hip joint

  With this configuration, when the lower limb training is performed, the lower body wear main body is attached to the body, and each of the elastic belts is stretched with both hands, brought into contact with the side of the hip joint, and further pulled up to the back side. Further, the hand is changed to the traction operation belt, the elastic belt is brought into contact with the buttocks, and is crossed when approaching the vicinity of the sacrum, and the traction operation belt is rotated from the side of the waist to the front of the abdomen.

  Then, the respective pulling operation belts are passed through the long holes of the respective locking pieces in the buckle, and are pulled out in the opposite directions from the long holes, so that the first thigh towing belt and the second thigh towing Tension is forcibly applied to the oblique belt, the telescopic belt and the traction operation belt. As a result, the thigh is pulled from the medial rear, thereby demonstrating the effect of guiding the hip joint in the external rotation / extension direction, assisting the activities of muscle groups that externally rotate / extend the hip joint, and position the hip joint in the intermediate position. To guide.

  The first thigh towing belt and the second thigh towing belt pull the thigh from the inner rear surface in the outward rotation direction, and the hip joint is in an unstable state of internal rotation / bending. In contrast to the flexion / extension action of the adductor muscle group that reduces the activity, the adductor muscle group acts on the flexion and extension of the hip joint by rotating the thigh. In addition, traction in the external rotation / extension direction with respect to the internal rotation / flexion position of the hip joint is a force that pulls the vicinity of the pubic bone, which is the origin of the adductor muscle group, leading to the effect of guiding the hip joint to the intermediate position. At the same time, the pelvis is also guided to the middle position.

  In this case, the stretchability and elasticity of the stretchable belt connected to the first thigh towing belt and the second thigh towing belt controls the tension for external rotation and extension of the hip joint. , Does not limit the internal rotation and bending movements that occur during active movement. In addition, the elastic belt crosses the sacrum from the outside of the hip joint and crosses the sacrum to compress and stimulate the greater gluteal muscle, which is the external rotation and extension muscle of the hip joint, thereby promoting muscle contraction of the greater gluteal muscle, By squeezing from behind, the pelvis in the forward tilt position is guided to the intermediate position.

  According to the present invention, the internal rotation / bending motion generated in the hip joint by receiving an external load or exercise load is induced in the external rotation / extension direction, and the hip joint is guided to the intermediate position, thereby causing the internal rotation / The unstable state of the hip joint caused by bending can be reduced, and the hip joint can be stably activated without restricting the operation of the hip joint. As a result, muscle fatigue in muscle activity can be avoided, and the occurrence of back pain and hip joint pain can be prevented or alleviated.

  The present invention has been briefly described above. The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings.

It is a front view which shows the hip joint stabilization wear by embodiment of this invention. It is a rear view of the hip joint stabilization wear shown in FIG. It is a perspective view which shows the buckle in FIG. It is explanatory drawing of the use condition of the hip joint stabilization wear shown in FIG. It is another explanatory drawing of the use condition of the hip joint stabilization wear shown in FIG. It is another explanatory drawing of the use condition of the hip joint stabilization wear shown in FIG. It is explanatory drawing which looked at the use condition of the hip joint stabilization wear shown in FIG. 1 from the diagonal direction.

  Hereinafter, hip joint stabilization wear according to an embodiment of the present invention will be described with reference to FIGS.

  First, in describing the hip joint stabilization wear, the tissue structure of the hip joint will be described. The hip joint has a ligamentous restriction at the front and a structure with a small amount of muscle fibers. On the contrary, there is little restriction of ligaments in the rear, and the structure has a large amount of muscle fibers. The Z ligaments (iliac femoral ligaments, pubic femoral ligaments) in front of the hip joints are tightened by external rotation and extension of the hip joints, and relaxed by internal rotation and flexion.

  In the anatomy, at the intermediate position (stable position) of the hip joint, the pelvis tends to incline backward on the femur due to gravity, and the Z ligament in front of the hip joint becomes slightly strained. In addition, since the main function of the muscle fiber behind the hip joint is the external rotation / extension movement of the hip joint, the contraction of the muscle fiber behind the hip joint is a movement of tilting the pelvis backward on the femur. For this reason, moving the hip joint in the flexion / internal rotation to the intermediate position has a function of stabilizing the hip joint. In other words, at the intermediate position of the hip joint, the pelvis tends to incline backward on the femur due to gravity, so that the muscle fibers behind the hip joint are in a stable state with reduced activity.

  According to this anatomical fact, when the internal rotation / flexion of the hip joint is continued, the muscle fibers behind the hip joint are in a state of reduced contraction, and the decrease in muscle activity is the hip joint The lack of posterior ligaments creates an unstable hip joint.

  On the other hand, the fact that the hip joint is in the intermediate position means that the pelvis is also in the intermediate position. That is, a decrease in stability in the internal rotation / flexion position of the hip joint results in tilting the pelvis. This is because the lumbosacral joint and sacroiliac joint, which passively pass the weight of the upper body, have the direction of passively tilting the pelvis forward by passing the weight of the upper body. This is because the natural condition will inevitably cause the pelvis to fall to the free leg side due to gravity.

  This change in the pelvis changes the normal bending state of the spine, and the valgus of the lower limbs is excessive due to the internal rotation of the hip joint, and the plantar acetabulum is changed. That is, the reduction of the internal rotation generated in the hip joint leads to stabilization of the body.

  As described above, in the internal rotation and flexion positions of the hip joint in which the Z ligament is loose, deformation of the plantar acetabulum, inclination of the knee joint, and change in the spinal curvature are likely to occur, and such a condition occurs in anyone. If it is a joint displacement but the body moves (activates) in that state, it becomes an exercise in a state where the muscle contraction rate behind the crotch joint is reduced. For this reason, the muscle activity around the hip joint other than the hip joint and the frequency of muscle activity around the hip and abdomen are increased to compensate for the movement of muscle fibers behind the hip joint, the muscle activity around the hip joint and the waist, Abdominal muscles are fatigued.

  This muscle fatigue causes pain, and back pain and hip joint pain also occur due to the muscle fatigue. On the other hand, if the hip movement is guided in the external rotation / extension direction without restricting the movement of the hip joint, the movement from any limb position to the stable limb position of the hip joint, It will normalize muscle activity. As a result, low back pain and hip joint pain can be alleviated. In addition, making the hip joint movement to a stable position (inducing) stabilizes muscle activity against lower limb training, sports, postpartum pelvic distortion, etc., and also protects the joint.

  The hip joint stabilization wear according to the present invention is made from such a viewpoint, and an embodiment of the hip joint stabilization wear will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the hip joint stabilization wear of this embodiment includes a lower body wear main body 11, a thigh towing vertical belt 12, a first thigh towing diagonal belt 13, A second thigh diagonal belt 14, a telescopic belt 15, and a traction operation belt 16 are provided.

  Among these, the lower body wear main body 11 is formed of a stretchable material having a frictional resistance that does not cause a positional shift with the skin, and covers at least an intermediate portion between the hip and the knee joint. Predetermined size and form. This lower body wear body 11 is made of nylon, polyurethane or various elastic materials including these, and for sports such as athletic wear, swimming competition swimwear, golf underwear, etc. It is made for back pain relief and massage effect.

  The longitudinal belt 12 for pulling the thigh is integrally provided in a corresponding portion of the inner body rear surface of the left and right thighs in the lower body wear body 11 in the longitudinal direction of the thigh. The longitudinal belt 12 for pulling the thigh is integrated with the lower body wear main body 11 so that the entire surface is in close contact by sewing or bonding. The thigh vertical pulling belt 12 has a feeling of pressure when the belt width is too thin. For example, the vertical belt 12 has a width of 4 to 5 cm, and reaches a lower thigh from the crotch part of the lower body wear main body 11 as a pair. It is provided integrally in the area. Further, the thigh traction vertical belt 12 is formed as one traction band by a material having stretchability and toughness substantially the same as the lower body wear main body 11.

One end of the first thigh pulling slant belt 13 is connected to the top end of the thigh pulling vertical belt 12 so as to incline gently in a slanting direction, and the corresponding part of the front part of the hip joint from the thigh inner side surface. Are integrally provided. This first thigh pulling slant belt 13 is integrated with the lower body wear main body 11 so that the entire surface is in close contact by sewing or bonding. In addition, the first oblique thigh pulling belt 13 is, for example , 4 to 5 cm wide as described above, and is integrally provided in a region extending from the inner side of the thigh of the lower body wear 11 main body to the side of the hip joint. Yes. Further, this first thigh towing belt 13 for pulling the thigh is made of a material having substantially the same stretchability and toughness as the lower body wear main body 11 as one pulling belt.

  One end of the second thigh towing belt 14 is connected to the lower end of the thigh vertical belt 12 so as to incline greatly in an oblique direction, and further, the thigh inner surface corresponds to the front of the thigh. The other end of the first thigh pulling diagonal belt 13 is integrally connected to the other end. The second thigh pulling slant belt 14 is integrated with the lower body wear body 11 so that the entire surface is in close contact with the lower body garment body 11 by stitching or bonding. The second slanting thigh belt 14 has a width of 4 to 5 cm, for example, and is integrally provided in a region extending from the inner side of the thigh of the lower body wear main body 11 to the crotch side. Further, the second diagonal thigh belt 14 for pulling the thigh is made of a material having stretchability and toughness substantially equal to the lower body wear main body 11 as a single pulling belt.

  The elastic belt 15 is connected to the connecting portion of the first thigh towing diagonal belt 13 and the second thigh towing oblique belt 14 and can be brought into contact with the hip joint from the outside through the hip. It has become. The stretchable belt 15 is not integrated with the lower body wear main body 11, has a length from the hip joint side to the buttocks, and the width is preferably 4 to 5 cm, for example. The stretchable belt 15 is made of a material having a large stretch rate and a strong contraction force as compared with the lower body wear 11 and the thigh towing diagonal belts 13 and 14.

One end of the pulling operation belt 16 is connected to the end of the telescopic belt 15 opposite to the connecting portion, and the region corresponding to the side and front of the upper waist from the vicinity of the sacrum and the abdomen. is guided in contact, the other end portion with respect to the buckle 17 as shown in FIG. 3 in the abdomen of its is locked length adjustably engaged. The buckle 17 has a pair of long holes 17b and 17c in two substantially rectangular locking pieces 17a, and the long holes 17b and 17b of the locking holes 17a facing each other have a buckle belt 17d. Each end is connected by sewing or the like.

  The elongated holes 17c and 17c are configured such that the traction operation belt 16 can be inserted therethrough. Therefore, by gripping both ends of the traction operation belt 16 with both hands in this inserted state and pulling it away from the locking piece 17a, the traction operation belt 16 is locked in the elongated hole 17c at the position where the drawing is stopped. It is possible. For this reason, as shown in FIG. 6, the traction operation belt 16 has a plurality of sawtooth (ratchet-like) locking claws 18 on its surface that can be locked and unlocked with respect to the long hole 7c. It is a parallel installation. Note that the configuration of locking and unlocking the buckle 17 and the traction operation belt 16 with respect to the buckle 17 is not limited to the above, and any known one can be selected and used.

  In the hip joint stabilization wear configured as described above, by pulling the end of each traction operation belt 16, the hip joint is externally rotated and extended while each elastic belt 15 and each thigh traction diagonal belt 13, 14 are tensioned. Can be made.

  Next, an operation of externally rotating and extending the hip joint using the hip joint stabilization wear having such a configuration will be described. First, when the lower limb training is performed, as shown in FIG. 4, the lower body wear main body 11 is attached to the body. The lower body wearable main body 11 has both the first thigh towing slant belt 13 and the second thigh slant belt 14 connected to the telescopic bell 15 in both hands. Is lifted diagonally upward and brought into contact with the side of the hip joint, and further turned to the back.

  Next, in this state, the hand is moved to the traction operation belt 16 while shifting the hand from the elastic belt 15. Then, when these traction operation belts 16 are brought into contact with the buttocks and further approached to the vicinity of the sacrum, both ends of each traction operation belt 16 are changed and crossed as shown in FIG. Turn forward.

  Then, a buckle 17 is prepared in front of the abdomen, the tip of the traction operation belt 16 is passed through the long hole 17c of each locking piece 17a, and the vicinity of each tip is held firmly with both hands. As shown in FIG. As a result, a tension force is forcibly applied to the first thigh towing diagonal belt 13, the second thigh towing oblique belt 14, the telescopic belt 15, and the towing operation belt 16. Therefore, the crotch part, the thigh part, the waist part, and the buttocks part corresponding to these parts are in a tightly bound state.

  Further, such a tight binding state is released by loosening the hand holding the traction operation belt 16. By releasing the binding, a repulsive force (contraction force) in the direction of releasing the tension acts on the traction operation belt 16, so that any one of the locking claws 18 on the surface of the traction operation belt 16 It is hooked (locked) to the locking edge of the long hole 17c in the locking piece 17a.

  Therefore, the traction operation belt 16 does not come out of the long hole 17c. That is, the traction operation belt 16 is connected to the first thigh towing diagonal belt 13, the second thigh towing oblique belt 14, the telescopic belt 15, and the traction operation belt 16 at the engagement position by the buckle. The tension will be maintained.

  As a result, the tension of the first thigh towing diagonal belt 13, the second thigh towing oblique belt 14, the telescopic belt 15 and the towing operation belt 16 pulls the thigh from the inner rear. Thus, the effect of inducing the hip joint in the external rotation / extension direction is exhibited, and the activity of the muscle group for external rotation / extension of the hip joint is assisted to guide the hip joint to the intermediate position.

  Further, the first thigh towing belt 13 and the second thigh towing belt 14 are connected to the upper and lower ends of the thigh vertical belt 12 at the rear inside the thigh, The thigh is externally pulled against the flexion / extension action of the adductor muscle group, which reduces the activity in the unstable state of internal rotation / flexion of the hip joint. By rotating it, the adductor muscle group can act on the flexion and extension of the hip joint. In addition, traction in the external rotation / extension direction with respect to the internal rotation / flexion position of the hip joint is a force that pulls the vicinity of the pubic bone, which is the origin of the adductor muscle group, leading to the effect of guiding the hip joint to the intermediate position. At the same time, the pelvis is also guided to the middle position.

  The stretchability and elasticity of the stretchable belt 15 connected to the first thigh towing diagonal belt 13 and the second thigh towing oblique belt 14 control the tension for external rotation and extension of the hip joint, It does not limit the internal rotation / bending motion that occurs during active movement. In addition, the elastic belt 15 crosses in the vicinity of the sacrum through the buttocks from the outside of the hip joint to compress and stimulate the greater gluteal muscle, which is the external rotation / extension muscle of the hip joint, thereby promoting muscle contraction of the greater gluteal muscle, In addition, the sacrum is pressed from behind, and the pelvis in the forward tilt position is guided to the intermediate position.

  Further, as described above, since a large number of serrated locking claws 18 are provided on the surface of each traction operation belt 16, the tip of each traction operation belt 16 is engaged with the buckle 17. By passing through the long hole 17c of the stop piece 18 and grasping the tip with both hands and pulling in the opposite directions as shown in FIG. 6, the first diagonal thigh belt 13 and the second large belt Tension can be applied intensively to the oblique thigh belt 14, the elastic belt 15 and the traction operation belt 16. Further, by adjusting the tension force, the tension force can be freely adjusted, and the external rotation / extension force of the crotch portion can be stably and properly fixed.

  Further, the first thigh towing diagonal belt 13, the second thigh towing oblique belt 14, the telescopic belt 15 and the towing operation belt 16 are not configured to go around the hip joint. Do not tighten the groin. As a result, there is no feeling of pressure when worn on the body, the joint motion is not restricted, and body fluid reflux is not inhibited. Then, the hip joint is guided in the external rotation / extension direction.

  The lower body wear body 11 to be attached to the thigh includes a short pants type that ends in the middle of the hip and knee joint from the vicinity of the waist, a spats type that ends at the upper hip joint, a semi-long spats type that ends at the lower hip joint, Any type such as a long spats type that ends at the upper part of the ankle and a tights type that covers the foot part can be adopted. Further, it is important that the lower-body wear main body 11 is made of a stretchable material that does not shift due to the traction due to friction with the thigh and does not excessively press the thigh.

As described above, the hip joint stabilization wear according to the present embodiment includes the lower body wear body 11 that covers at least the middle part between the crotch and the upper knee joint from the lower back. A thigh vertical belt 12 is integrally provided in the longitudinal direction of the thigh at the corresponding portion of the thigh inner rear surface. The first thigh towing slant belt 13 is integrally provided on the upper end of the thigh towing vertical belt 12 so as to be inclined gently in an oblique direction from the inner surface of the thigh to the corresponding part of the front of the hip joint. One end is connected. The lower end of the thigh pulling vertical belt 12 is integrally provided at a corresponding portion of the thigh front surface from the inner surface of the thigh so as to be greatly inclined in an oblique direction, and one end thereof is the first thigh. One end of a second thigh diagonal belt 14 integrated with the end of the diagonal belt 13 is connected. The first thigh pulling slant belt 13 and the second thigh pulling slant belt 14 are brought into contact with the connecting portions at the other ends so as to cross in the vicinity of the sacrum from the hip joint outside through the buttocks. that connects the end portions of the predetermined length of the telescopic belt 15, the other end of these telescopic belts 15 is guided so as to be in contact with the portion corresponding to the side and the front waist upper from the vicinity of the sacrum, in the waist front of their connecting the respective one end of the traction belt 16 is latched length adjustably engaged with the buckle 17, by pulling the other end of each traction belt 16 through the buckle 17, The hip joint is externally rotated and extended while the thigh pulling oblique belts 13 and 14 are tensioned via the respective elastic belts 15.

  With this configuration, the traction operation belt 16 is passed through the elongated holes 17c of the respective locking pieces 17a in the buckle 17 and pulled out in opposite directions to each other, and the first thigh traction diagonal belt 13 and the second thigh A tension force is forcibly applied to the oblique belt 14 for towing the belt, the telescopic belt 15 and the belt 16 for towing operation. As a result, the thigh is pulled from the inner rear, and the effect of guiding the hip joint in the external rotation / extension direction is exhibited, and the activity of the muscle group that externally rotates / extends the hip joint is assisted to guide the hip joint to the intermediate position. can do.

  Further, the first thigh towing diagonal belt 13 and the second thigh towing belt 14 pull the thigh from the inner rear surface in the outward rotation direction, and the hip joint is unstable because of internal rotation and bending. In contrast to the flexion / extension action of the adductor muscle group that reduces activity in a state, the adductor muscle group can act on the flexion and extension of the hip joint by rotating the thigh. In addition, traction in the external rotation / extension direction with respect to the internal rotation / flexion position of the hip joint is a force that pulls the vicinity of the pubic bone, which is the origin of the adductor muscle group, leading to the effect of guiding the hip joint to the intermediate position. At the same time, the pelvis is also guided to the middle position. Accordingly, it is possible to effectively perform lower limb training and sports while protecting the joints without causing muscle fatigue or inducing muscle pain while further reducing back pain and hip joint pain.

  The hip joint stabilization wear of the present invention induces the internal rotation / bending motion generated in the hip joint in the external rotation / extension direction and guides the hip joint to the intermediate position, thereby causing the unstable state of the hip joint caused by the internal rotation / flexion of the hip joint. Hip stabilization wear that has the effect of reducing hips and allowing the hip joint to be stably operated without restricting the movement of the hip joint, and is used by being mounted on the hip joint part and stabilizing the activity of this joint Etc. are useful.
