Description

  The present invention relates to a knee-worn body for wearing on a knee.

  Conventionally, many wears for the lower body have been proposed for improving or supporting the motor function of the legs.

  As one example of this type of wear, for example, a lower-body wear having a taping function that can support an easily damaged part such as a knee is known (Patent Document 1).

  This wear has a body cloth, a tightening force higher than that of the body cloth, an inner belt-like piece disposed inside the patella portion so as to avoid the patella portion, a tightening force higher than that of the body cloth, and a patella. And an outer belt-like piece arranged so as to avoid the patella portion, and the inner belt-like piece and the outer belt-like piece intersect with each other above and below the patella portion.

  The above-mentioned wear is designed to support the knee by arranging the inner and outer strips, which have higher tightening force than the body cloth, avoiding the patella and intersecting above and below the patella. is there.

Japanese Patent Publication No. 6-41641

  In the above conventional wear, the inner and outer band-like pieces having higher tightening force than the body cloth are arranged so as to surround the patella part, and the periphery of the patella part is tightened in the circumferential direction in the worn state. . For this reason, the conventional wear is able to reduce the burden on the knee because the knee is fixed in the stance phase, which is a phase in which the leg contacts the ground during running, for example. However, the conventional wear is not considered for promoting the knee extension operation in the stance phase. Further, the conventional wear is not easy to bend the legs because the support force is too effective during the swing leg phase in which the legs are separated from the ground during the running operation. As described above, the conventional wear does not focus on facilitating the running operation and has room for improvement.

  Then, this invention makes it a subject to provide the knee-wearing body which can make a running operation easy in view of this situation.

  The knee-worn body according to the present invention has one or more central high-rigidity portions extending in the length direction, which has a rigidity higher than that of the body cloth, and is pretensioned in the length direction in a worn state, A central high-rigidity portion that is disposed across the knee flexion-extension axis, which is the center of flexion and extension of the wearer's knee, in the length direction, and the central high-rigidity portion on the upper side of the knee flexion-extension axis in the length direction. An upper anchor for fixing the position with respect to the center, and a lower anchor for fixing the position of the central high rigidity portion to the wearer below the knee flexion and extension axis in the height direction, A knee-corresponding portion that is positioned corresponding to the knee of the wearer and is disposed across the knee flexion-extension axis in the lengthwise direction, the knee-corresponding portion passing through the center in the width direction of the leg, A patella extending in the anterior-posterior direction of the knee through the leg center axis and the patella center In a position deviated laterally with respect to the knee longitudinal plane containing the mandrel, and is arranged to be positioned in front of the and knees lateral surface including the knee bending axis and the leg central axis.

  According to such a configuration, the knee corresponding part slides sideways from the front side of the knee along the knee slope along with the knee bending motion. In this way, the knee corresponding portion slides so as to retract to the side along with the knee bending operation, and thus it is difficult to hinder the knee bending operation. In addition, a restoring force corresponding to the amount of elongation associated with the pretension and the bending operation is applied to the knee corresponding portion in a state where the knee is bent. Therefore, the knee corresponding portion returns to the original position along with the knee extension operation and pulls in the direction in which the knee is extended, so that the knee extension operation can be promoted.

  As another aspect of the present invention, the central high-rigidity portion includes an inner central high-rigidity portion disposed on the inner side of the knee with respect to the front and rear surfaces of the knee, and an outer central high-rigidity portion disposed on the outer side of the knee. The inner central high-rigidity part and the outer central high-rigidity part may be arranged so as to be separated on both the upper and lower sides in the length direction.

  According to such a configuration, the inner center high-rigidity portion and the outer center high-rigidity portion are arranged so as to be separated on both the upper and lower sides in the length direction. For this reason, the inner central high-rigidity portion and the outer central high-rigidity portion easily slide in a direction away from each other on the upper and lower sides in the length direction along with the bending motion of the knee, and hardly hinder the knee bending motion.

  As another aspect of the present invention, the knee-worn body is located on the upper side of the central high-rigidity part in the height direction, and is connected to the upper anchor, and the central high-rigidity in the height direction. A lower high-rigidity portion that is located on the lower side of the portion and connected to the lower anchor, wherein the upper high-rigidity portion and the lower high-rigidity portion are higher in rigidity than the rigidity of the central high-rigidity portion. You may have.

  According to this configuration, the upper high rigidity portion is connected to the upper anchor, the lower high rigidity portion is connected to the lower anchor, and the upper high rigidity portion and the lower high rigidity portion are more rigid than the rigidity of the central high rigidity portion. High rigidity. That is, the central high-rigidity portion having relatively low rigidity is disposed in the portion that is most extended during the knee flexion movement, and the upper high-rigidity portion and lower high-rigidity having relatively high rigidity are provided in the portion having relatively small elongation. Parts are arranged. Therefore, when the knee is bent, the upper high rigidity portion and the lower high rigidity portion hardly extend, and the upper high rigidity portion and the lower high rigidity portion exert an anchor effect, and the central high rigidity portion is preferentially extended. be able to. As described above, the knee-worn body having the above-described configuration can apply a restoring force to the central high-rigidity portion by preferentially extending the central high-rigidity portion. Compared with the case where the lower high-rigidity portion has the same rigidity, the effect of promoting the knee extension operation is high.

  In this case, the rigidity of the upper high-rigidity part and the lower high-rigidity part may be 1.1 times or more and 120 times or less than the rigidity of the central high-rigidity part.

  According to such a configuration, the upper high-rigidity portion and the lower high-rigidity portion have sufficiently high rigidity with respect to the central high-rigidity portion. The effect of preferentially extending can be improved.

  As another aspect of the present invention, the central high-rigidity portion includes an inner central high-rigidity portion arranged inside the knee and an outer central high-rigidity portion arranged outside the knee with respect to the front and rear surfaces of the knee. The inner center high-rigidity portion is located above the inner knee corresponding portion as the knee corresponding portion in the length direction, and has an inner thigh corresponding portion positioned corresponding to the thigh, and the outer center The high-rigidity portion is located on the upper side of the outer knee corresponding portion as the knee corresponding portion in the length direction, and has an outer thigh corresponding portion positioned corresponding to the thigh. It may be arranged so as to pass on the inner vastus ridge that is the bulge of the muscle, and the outer thigh corresponding part may be arranged so as to pass on the outer vastus ridge that is the ridge of the thigh muscle.

  According to such a configuration, the inner thigh corresponding part is disposed so as to pass over the inner vastus ridge part that is the thigh muscle ridge part, and the outer thigh corresponding part is the thigh muscle ridge part. It is arranged to pass over the outer vastus ridge. With this arrangement, the inner central high-rigidity portion and the outer central high-rigidity portion are stretched between the raised portion and the knee in a state where the knee is extended, and the adhesion to the knee is reduced. Therefore, the inner central high-rigidity part and the outer central high-rigidity part are easily slid from the front side of the knee toward the side along with the knee bending operation.

  As another aspect of the present invention, the lower anchor may be configured to be hookable on the sole.

  According to such a configuration, the lower end side of the central high-rigidity portion can be firmly fixed to the wearer, so that the central high-rigidity portion can be prevented from shifting in the length direction.

  As another aspect of the present invention, the central high-rigidity part may be arranged so that at least the knee corresponding part is not connected to the body cloth.

  According to such a configuration, the knee-corresponding portion easily slides with respect to the body cloth during the knee bending operation, so that the central high-rigidity portion is easily displaced to the side of the knee.

  A knee-worn body according to the present invention includes a body cloth having a front body, and a knee flexion / extension shaft having rigidity higher than that of the body cloth and extending in a width direction of the front body through a knee portion of the front body. A high-rigid body that is disposed across the corresponding line in the length direction, an upper anchor that fixes the upper end of the high-rigid body relative to the wearer, and a lower end of the high-rigid body that is positioned relative to the wearer A lower anchor for fixing, wherein the high-rigidity body is positioned corresponding to the knee, and the knee corresponding portion is disposed across the knee flexion-extension axis corresponding line in the length direction, and the knee An upper high-rigidity part located on the upper side in the height direction than the corresponding part; and a lower high-rigidity part located on the lower side in the height direction than the knee-corresponding part, wherein the knee-corresponding part is in the width direction It is arranged at a position that is laterally deviated with respect to the body cloth center line extending in the length direction through the center, and the knee pair Rigid parts are, the rigidity of the upper high-rigidity area, and may be lower than the rigidity of the lower rigid part.

  According to such a configuration, the knee-corresponding portion is disposed on the front side of the knee and on the slope of the knee in a worn state. The knee-corresponding portion is gradually extended in the length direction as the knee bends, and the tension applied to the knee-corresponding portion gradually increases. Therefore, the knee corresponding part shifts from the front side of the knee to the side along the slope of the knee so as to balance the force. As described above, the knee corresponding portion retreats to the side from the most extended portion of the knee in accordance with the knee bending operation, and therefore it is difficult to hinder the knee bending operation. Further, a restoring force corresponding to the amount of elongation associated with the bending action is applied to the knee corresponding portion in a state where the knee is bent. Therefore, the knee corresponding portion returns to the original position and pulls in the direction in which the knee is extended in accordance with the knee extension operation, so that the knee extension operation can be promoted.

  In addition, a knee-corresponding portion having a relatively low rigidity is arranged in the portion that is most extended during the bending operation of the knee, and an upper high-rigidity portion and a lower high-rigidity portion that are relatively high in rigidity in a portion that is relatively small in elongation. Is placed. Therefore, when the knee bends, the upper high rigidity part and the lower high rigidity part hardly extend, and the upper high rigidity part and the lower high rigidity part exert an anchor effect to preferentially extend the knee corresponding part. Can do. As described above, the knee-worn body having the above-described configuration can apply a restoring force to the knee-corresponding portion in a concentrated manner by preferentially extending the knee-corresponding portion. Compared to the case where the high rigidity portion has the same rigidity, the effect of promoting the knee extension operation is high.

  In this case, the rigidity of the upper high rigidity part and the lower high rigidity part may be 1.1 times or more and 120 times or less than the rigidity of the knee corresponding part.

  According to such a configuration, the upper high-rigidity portion and the lower high-rigidity portion have sufficiently high rigidity with respect to the knee-corresponding portion. Can be improved.

  Further, in this case, the high-rigidity body may be composed of the same cloth as a whole, and the knee corresponding part may be formed thinner than the upper high-rigidity part and the lower high-rigidity part.

  According to such a configuration, the knee corresponding part is made thinner than the upper high rigidity part and the lower high rigidity part, and the knee corresponding part has a rigidity higher than that of the upper high rigidity part and the lower high rigidity part. Since it can be made low, a low-rigidity part can be formed easily.

  Further, in this case, at least one of a connection portion between the knee corresponding portion and the upper high rigidity portion and a connection portion between the knee corresponding portion and the lower high rigidity portion is directed toward the knee corresponding portion. You may form so that a width | variety may become narrow gradually.

  According to such a configuration, it is possible to suppress stress from being concentrated on the connection portion even when the knee corresponding portion is pulled, and it is possible to prevent the high-rigid body from being damaged.

  The method for wearing a knee-worn body according to the present invention has one or more central high-rigidity portions that have rigidity higher than that of the body cloth and extend in the length direction, and correspond to the wearer's knee. A central high-rigidity portion having a knee-corresponding portion located, and a knee-high-extension shaft that is disposed across the knee-flexion-extension axis, which is the center of flexion and extension of the knee, in the height direction; An upper anchor for fixing the position to the wearer on the upper side of the knee, and a lower anchor for fixing the position of the central high-rigidity part to the wearer on the lower side of the knee flexion and extension axis in the length direction. A method of wearing a wearer, wherein the upper anchor is fixed at the upper side of the knee flexion and extension axis, and the lower anchor is fixed at the lower side of the knee flexion and extension axis, and the knee corresponding portion is fixed to the knee Place the bending and stretching axis so as to straddle up and down in the length direction, wearing state of the knee corresponding part The length in the length direction is 1.1 times or more and 3.0 times or less the length in the length direction of the knee corresponding part before wearing, and the knee corresponding part is A position dislocated laterally with respect to the front and back surfaces of the knee including a leg central axis extending in the length direction through the center in the width direction of the leg and a patella central axis extending in the front and rear direction of the knee through the center of the patella, and You may arrange | position so that it may be located in the front side rather than the knee right-and-left surface containing a knee bending extension axis and the said leg central axis.

  According to such a method for wearing a knee-worn body, the knee-corresponding portion shifts from the front side of the knee to the side along with the knee bending operation, and therefore, it is difficult to inhibit the knee bending operation. Moreover, since the knee corresponding part is pulled in the direction in which the knee is extended in accordance with the extension operation of the knee, the extension operation of the knee can be promoted.

  As described above, according to the present invention, it is possible to provide a knee-worn body that can easily perform a running operation.

  Hereinafter, a knee wearing body according to an embodiment of the present invention will be described with reference to the drawings.

  Since the knee-worn body 1 according to the present embodiment is for facilitating human running motion, the human running motion will be described first. During the running operation, the person repeats the operation of grounding the leg to the ground and the operation of separating the leg from the ground. The period when the leg is in contact with the ground is called the stance phase, and the period when the leg is away from the ground is called the swing phase. Fig.1 (a) and FIG.1 (b) have shown the state in the stance phase of a right leg. FIG.1 (c) and FIG.1 (d) have shown the state in the free leg period of a right leg.

  As shown in FIG. 1 (a), the knee bending angle R is an axis set along the direction in which the thigh extends, and the axis set along the direction in which the crus extend as the axis set along the direction in which the thigh extends. The lower leg axis T is an angle formed by the upper leg axis S and the lower leg axis T. Specifically, the knee flexion angle R is an angle formed by a thigh axis extension line and a crus axis T, which is a line obtained by extending the thigh axis S to the knee side. In the phase of transition from the stance phase to the swing phase from FIG. 1B to FIG. 1C, the person bends the knee greatly. During this period, there is no significant contraction in the muscles around the knee joint (for example, the quadriceps), and the bending action is mainly performed by the inertial force generated by kicking the ground. Then, as shown in FIG.1 (d), a leg is swung out ahead and transfers to a stance phase. In the stance phase, the person extends the knee. During this period, the knee flexion movement is controlled by contraction of the muscles around the knee joint. The knee flexion angle R during the swing phase is approximately 60 to 120 degrees. The knee flexion angle R in the stance phase is approximately 30 to 50 degrees. That is, the knee in the stance phase bends twice or more than the knee in the stance phase. Conventional wear has a structure that makes it difficult to bend the knee, which also affects the swing of the leg. That is, in the conventional wear, the wearer is less likely to swing out the leg, and the stride is narrowed because the knee is difficult to bend. Attempting to stretch the stride puts extra strain on the muscles, resulting in reduced wearer performance. The knee-wearing body 1 according to this embodiment does not hinder the knee bending operation and assists the knee extension force.

  As shown in FIGS. 2 and 5, the knee-worn body 1 of the present embodiment has a body cloth 2 and a central high rigidity that has higher rigidity than the body cloth 2 and is pretensioned in the length direction in the worn state. A central high-rigidity portion 3 that is disposed across the knee flexion-extension axis X, which is the center of knee flexion and extension, in the length direction, and the central high-rigidity portion 3 on the upper side of the knee flexion-extension axis X in the length direction. An upper anchor 4 for fixing the position to the wearer and a lower anchor 5 for fixing the position of the central high-rigidity portion 3 to the wearer below the knee flexion / extension axis X in the length direction are provided. In the present embodiment, the knee-worn body 1 includes an upper high-rigidity portion 6 located above the central high-rigidity portion 3 in the length direction and a lower high-rigidity portion 7 located below the central high-rigidity portion 3 in the length direction. With. The knee flexion / extension axis X of the present embodiment is a line connecting the medial epicondyle and lateral epicondyle of the femur. “Rigidity” in the present embodiment is measured by a tensile tester (“Autograph Precision Universal Tester” manufactured by Shimadzu Corporation). As a measurement condition, the strain rate was 200% per minute.

  The pre-tensioned state is a state where the wearer's knee is not bent (a state where the knee is extended), and the central high-rigidity portion 3 is extended in the length direction. In other words, in the wearing state, the central high-rigidity portion 3 is in a state where a restoring force is applied to return to the original length. Note that conventional exercise tights, spats, etc. are also made of stretchable fabric, so that some tension is applied. However, in this embodiment, the pre-tensioned state is the above-described conventional exercise Unlike the state in which tension is applied in the tights, spats, etc., this is a state in which a feeling of wearing such that the knee is stretched greatly in the direction in which the knee extends in the wearing state. In this embodiment, as a wearing state, it is assumed that a wearer having an appropriate body shape wears the knee-worn body 1 (particularly the size in the length direction), and pretension is applied in the wearing state. To do. For example, when the wearer wears a knee-wearing body 1 having a size larger than the size in the length direction of the wearer, the pretension assumed in the wearing state is not sufficiently applied. Becomes smaller.

  The body fabric 2 is configured to cover at least the wearer's leg. The body cloth 2 of the present embodiment is lower body wear. Specifically, the body cloth 2 is formed in a tights shape. The body cloth 2 includes a front body 2a and a back body 2b. The front body 2a is a portion that is located on the front side (front side of the wearer) when the body fabric 2 is placed on a flat surface so that the top of the crotch is located in the center in the width direction, and the back body 2b is It is a part located in the back side (back side of a wearer) in this state. The body fabric 2 includes a waist portion 21 covering the waist circumference of the wearer, a thigh portion 22 covering the circumference of the wearer's thigh, a knee portion 23 covering the circumference of the wearer's knee, and a lower part of the wearer. And a crus 24 covering the thigh region. The body cloth 2 is formed of a soft cloth having elasticity. As a preferable rigidity of the cloth body 2, for example, the load applied when 10% is extended is 0.4 N or less. For the body fabric 2, for example, a fabric for ordinary clothes such as a woven fabric or a knitted fabric can be used. Moreover, as a fiber which comprises the body cloth 2, polyester fiber, polyurethane fiber, acetate fiber, cotton fiber, rayon fiber, ethylene vinyl alcohol fiber, nylon fiber etc. can be used, for example. In the present embodiment, the body fabric 2 is formed to have a length of 10 minutes covering the leg from the waist to the ankle.

The central high-rigidity portion 3 is formed so that the rigidity in the length direction is higher than that of the body cloth 2. That is, the central high-rigidity portion 3 is less likely to extend at least in the length direction than the body cloth 2. In the present embodiment, the central high-rigidity portion 3 is formed by sewing a fabric having a higher elastic modulus than the body fabric 2 to the body fabric 2. The method of providing the central high-rigidity portion 3 is not limited to this, and the central high-rigidity portion 3 may be formed by printing a resin or the like on the body fabric 2, or a fabric having higher rigidity than the body fabric 2. Further, the central high rigidity portion 3 may be formed by printing a resin or the like. As a material for the central high-rigidity portion 3, for example, polyester, nylon, or the like can be used.
In the present embodiment, the central high-rigidity portion 3 is disposed so as to be inclined with respect to the side line 20 that is a boundary portion between the front body 2a and the back body 2b. Specifically, the central high-rigidity portion 3 is disposed so that the lower end is positioned on the patella center P side from the upper end. In the wearing state, the tension applied to the central high-rigidity portion 3 is greater than the tension applied to the body cloth 2.

  A preferable range of the rigidity of the central high-rigidity portion 3 is, for example, a load applied at 10% elongation of 0.4 N or more and 12 N or less.

The central high-rigidity portion 3 has a rectangular shape that extends long in the length direction, and may be linear or entirely curved, but is preferably linear. By forming the central high-rigidity portion 3 in a straight line, tension can be effectively applied in the longitudinal direction of the central high-rigidity portion 3, and the extension force of the muscles around the knee joint (for example, quadriceps) can be directly applied. Can be supplemented.
The width of the central high-rigidity part 3 is, for example, 1 cm to 10 cm, and preferably 1.5 cm to 7 cm. If the width of the central high-rigidity portion 3 is thinner than 1.5 cm, the central high-rigidity portion 3 is likely to bite into the wearer's skin and impairs the wearing feeling. On the other hand, if the width of the central high-rigidity portion 3 is larger than 7 cm, even if the central high-rigidity portion 3 slides to the side of the knee when the knee is bent, a part of the central high-rigidity portion 3 is likely to remain on the front side of the knee. May interfere with operation. Therefore, by making the width of the central high-rigidity part 3 in a range of 1.5 cm to 7 cm, it is possible to easily slide the entire central high-rigidity part 3 to the side of the knee without greatly impairing the wearing feeling.

  As shown in FIG. 5, the central high-rigidity part 3 has three parts, a knee corresponding part 31, a thigh corresponding part 32, and a crus corresponding part 33. The knee corresponding portion 31 is a portion that is positioned corresponding to the knee and is disposed so as to straddle the knee flexion / extension axis X in the length direction. The thigh corresponding part 32 is a part located above the knee corresponding part 31. The lower leg corresponding part 33 is a part located below the knee corresponding part 31. That is, the central high-rigidity part 3 has a part arranged so that the thigh corresponding part 32, the knee corresponding part 31, and the crus corresponding part 33 are arranged in this order from the upper side in the length direction. Of these three parts, the length in the length direction of the knee corresponding part 31 is the longest. In the wearing state, the central high-rigidity part 3 is arranged on the wearer's thigh (upper patella), and the lower end is the wearer's lower leg (below the patella, for example, the height position of the three legs of the leg). ).

  The position where the knee corresponding part 31 is disposed will be described in more detail. As shown in FIGS. 3 to 5, the knee corresponding portion 31 has a leg center axis Y extending in the length direction through the center in the width direction of the leg and a patella center axis Z extending in the front-rear direction of the knee through the patella center P. It is disposed so as to be laterally deviated with respect to the front and rear surface A including the knee and to be positioned in front of the left and right knees B including the knee flexion and extension axis X and the leg central axis Y. The patella center P is the intersection of the major axis in the width direction (left and right direction in FIG. 4) of the patella H and the major axis in the height direction (direction perpendicular to the left and right direction and front and rear direction in FIG. 4). The central high-rigidity part 3 is disposed along the inclined surface of the knee. FIG. 5 is an enlarged view around the knee of the right leg in a worn state. As shown in FIG. 5, the leg center axis Y is an axis passing through the center of the leg from the base of the thigh to the ankle in the center of the leg in the width direction with the leg straightly extended. As shown in FIG. 3, the leg central axis Y and the patella central axis Z define a knee front-rear surface A that extends in the front-rear direction of the knee. The knee flexion / extension axis X and the leg center axis Y define a knee lateral surface B extending to the left and right of the knee. FIG. 4 is a view of the cross-section of the wearer's right leg as viewed from above in the length direction, and is a view showing a state in which the patella H is located on the lower side in the vertical direction of the paper. That is, the right side in the left-right direction on the paper surface is the inside, and the left side in the left-right direction on the paper surface is the outside. 3 and 4, the knee flexion / extension axis X, the leg central axis Y, and the patella central axis Z are schematically shown. For convenience of explanation, FIGS. 3 and 4 show a case where the respective axes are orthogonal to each other. However, depending on the wearer's body shape, the respective axes may be inclined. Therefore, depending on the wearer's body shape, the knee front-rear surface A may be inclined with respect to the knee left-right surface B. 5 shows the case where the patella center P is located on the leg center axis Y for convenience of explanation, but the patella center P is located away from the leg center axis Y depending on the body shape of the wearer. It may be.

  The central high-rigidity portion 3 of the present embodiment is arranged such that at least the knee corresponding portion 31 is not connected to the body cloth 2. Specifically, in the central high-rigidity portion 3, the thigh corresponding portion 32 is connected to the upper high-rigidity portion 6, the crus corresponding portion 33 is connected to the lower high-rigidity portion 7, and the knee corresponding portion 31 is lifted from the body cloth 2. It is in the state. Since the knee corresponding part 31 is not restrained by the body cloth 2 by floating the knee corresponding part 31 from the body cloth 2 in this way, the knee corresponding part 31 is more easily slid to the knee side surface side.

  In the present embodiment, the central high-rigidity portion 3 includes an inner central high-rigidity portion 3a disposed inside the knee and an outer central high-rigidity portion 3b disposed outside the knee.

  As shown in FIGS. 2 and 5, the inner central high-rigidity portion 3 a includes an inner knee corresponding portion 31 a as the knee corresponding portion 31, an inner thigh corresponding portion 32 a as the thigh corresponding portion 32, and a lower leg corresponding portion 33. And an inner lower leg corresponding portion 33a. The inner central high-rigidity portion 3a is positioned from 0 degrees to 20 degrees so that the upper end is located on the inner side line 20a side and the lower end is located on the patella center P side with respect to the inner side line 20a of the side line 20 of the body cloth 2. Is tilted.

That is, the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b are arranged so as to gradually approach from the upper end side toward the lower end side. In general, since the thigh is thicker than the lower leg, the inner inclined surface H1 and the outer inclined surface H2 of the knee form a V shape that is closed toward the lower leg. Therefore, when the inner center high-rigidity portion 3a and the outer center high-rigidity portion 3b are arranged in a positional relationship such that the separation distance between the upper ends is wider than the separation distance between the lower ends, the inner center high-rigidity portion 3a and The outer center high-rigidity portion 3b is easily disposed along the inclined surface of the knee.

  The description of the knee-worn body 1 of the present embodiment is as described above. Hereinafter, the position of the central high-rigidity portion 3 during the running motion will be described based on the bending motion of the wearer's right leg.

  FIG. 7 is a front view of a state where the wearer has extended his knee, that is, a state where the wearer is standing upright. FIG. 8 is a side view of the knee on the inner side of FIG. 7. 9 is a side view of the knee on the outside of FIG. That is, in FIG. 8, the inner center high-rigidity portion 3a is visible, and in FIG. 9, the outer center high-rigidity portion 3b is visible. At this time, the knee flexion angle R is 0 degrees. A virtual circle D centered on the patella center P is set in a state where the knee bending angle R is 0 degree, and the positional relationship between the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b accompanying the bending operation is described. To do. In this state, the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b are located close to the front side of the knee.

  FIG. 10 is a front view of a state in which the wearer has bent the knee 45 degrees. FIG. 11 is a side view of the knee inside FIG. FIG. 12 is a side view of the knee on the outside of FIG. As shown in FIGS. 10 to 12, the inner central high-rigidity portion 3 a and the outer central high-rigidity portion 3 b are shifted to the side of the knee along with the knee bending movement, and the inner central high-rigidity portion 3 a and the outer central high-rigidity portion 3 b are displaced. The distance between the rigid portions 3b is increased. The separated state of the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b is apparent when referring to the virtual circle D in a state where the knee is extended. As shown in FIGS. 11 and 12, the inner center high-rigidity portion 3 a and the outer center high-rigidity portion 3 b are in a state of being displaced substantially to the side of the knee.

  FIG. 13 is a front view of a state in which the wearer has bent the knee 90 degrees. FIG. 14 is a side view of the knee on the inner side of FIG. 13. 15 is a side view of the knee on the outside of FIG. As shown in FIGS. 13 to 15, the inner central high-rigidity portion 3 a and the outer central high-rigidity portion 3 b are displaced further to the side of the knee than the state where the bending angle R is 45 degrees with the knee bending operation. Thus, the distance between the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b is increased. The separated state of the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b is apparent when referring to the virtual circle D when the knee is bent by 45 degrees. As shown in FIGS. 14 and 15, the inner central high-rigidity portion 3 a and the outer central high-rigidity portion 3 b are in a state of being displaced further to the side of the knee than the state where the bending angle R is 45 degrees.

  When the knee is extended from a bent state, the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b try to shrink so that tension is applied in a straight line. Pulling in the direction to extend the knee as and approaches. At the same time, the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b approach each other and move to the front side of the knee. As described above, the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b repeat approach and separation during the running operation.

  Hereinafter, the effect of the knee wearing body 1 of this embodiment is further demonstrated.

<First verification>
It verified about the effect which the knee-wearing body 1 of this embodiment shows in a stance phase. When three men as subjects are run at 10 km / h and no running wear is worn (ND), the angle formed by the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b is 40 degrees. When wearing the knee-worn body 1 arranged in such a manner (Wide), the knee-worn body 1 arranged so that the angle formed by the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b is 20 degrees. In this case (Narrow), the muscle activity of the quadriceps femoris (inner vastus medius) was measured by electromyography. The higher the measured value, the more active the muscle strength. That is, the lower the measured value, the smaller the load on the muscle strength.

  FIG. 16A is a plot of the average values of the measured values of three persons for each of ND, Wide, and Narrow in the stance phase. As is clear from FIG. 16A, in the stance phase, the measured value is smaller than that of ND in both Wide and Narrow. That is, when the knee wearing body 1 is worn, the burden on the quadriceps is smaller than ND. From this, it can be seen that the central high-rigidity part 3 assists the extension force of the quadriceps femoris.

<Second verification>
It verified about the effect which the knee-wearing body 1 of this embodiment show | plays in a swing leg period. The subject is the same as in the first verification. In each of ND, Wide, and Narrow, the bending angle R of the knee in the most bent state was measured. The state where the knee is extended is 0 degree, and the state where the knee is bent is a negative angle. That is, the smaller the knee flexion angle R, the more the knee is bent.

  FIG. 16B plots the average value of the flexion angles R of the three knees for each of ND, Wide, and Narrow during the swing phase. As is clear from FIG. 16B, the knee bending angle R in the Wide is the smallest. That is, it turns out that even if the knee-wearing body 1 is worn, the knee flexion is not hindered. When the angle formed by the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b is narrow from the knee bending angle R in the narrow state of FIG. 16B, the effect of promoting the knee extension operation is mainly used. You can see it. Therefore, it is preferable that the angle formed by the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b is 20 degrees or more.

<Third verification>
The strain applied to the central high-rigidity portion 3 due to the knee bending motion was measured with Wide and Narrow, and the effect of the knee-worn body 1 was verified. A strain sensor was attached along the central high-rigidity portion 3 to measure the magnitude of strain associated with knee flexion. Specifically, the knee is bent by a squat operation, and the knee bending angle R is 0 degree (the state shown in FIGS. 7 to 9) to 45 degrees (the state shown in FIGS. 10 to 12) and then 90 degrees. The operation of bending to (the state of FIGS. 13 to 15) was performed in 2 seconds. The knee was bent so that the bending angle R was 45 degrees one second after the start of bending. For the measurement of the strain, an elastic strain sensor (“C-STRECH (registered trademark)” manufactured by Bando Chemical Co., Ltd.) was used.

  As shown in FIG. 17, the central high-rigidity portion 3 extends around 10% at the start of bending (0 [sec]). From this, it can be seen that tension is applied in the length direction with the knee flexion angle R being 0 degrees. As the knee flexion angle R increases, the strain applied to the central high-rigidity portion 3 increases. That is, in the knee-worn body 1, the central high-rigidity portion 3 extends as the knee bends, so as the bending angle R increases, the tension applied to the central high-rigidity portion 3 increases, and the extension operation is promoted accordingly. can do.

  On the Wide side, the strain became substantially constant at the bending angle R of about 50 degrees (when 1.3 to 1.4 seconds had elapsed). From this, it can be seen that the central high-rigidity portion 3 is retracted from the portion (front surface) where the knee extends along with the bending motion of the knee. Since the strain of the central high rigidity portion 3 shows a substantially constant value until the knee is bent by 90 degrees, the knee bending operation is performed while the central high rigidity portion 3 is maintained in the extended state. I understand that. That is, it can be seen that the central high-rigidity portion 3 does not hinder the knee bending operation from a state where the knee is bent about 50 degrees to a state where the knee is bent 90 degrees. Furthermore, the strain in a worn state is around 10%, whereas the strain in a bent state of about 50 degrees exceeds 50%. Therefore, since the restoring force of the central high-rigidity part 3 is increased by the amount of increase in strain from the wearing state, it can be seen that the extension operation is assisted by that amount.

  In Narrow, the strain continued to increase until the knee flexed 90 degrees. In the case of Narrow, the restoring force applied to the central high-rigidity portion 3 is increased by the amount of distortion that is larger than that of Wide in a state where the knee is bent by 90 degrees. That is, it can be seen that Narrow has a stronger effect of promoting the knee extension movement.

  Hereinafter, the operation of the present embodiment will be summarized. According to the knee-worn body 1 of the present embodiment, the knee-corresponding portion 31 is fixed to the wearer while being stretched in the length direction in the wearing state, and straddles the knee flexion / extension axis X in the length direction. It is arrange | positioned so that it may be located in the front side rather than the knee right-and-left surface B in the position which remove | deviated from the knee front-and-back surface A side. With this arrangement, the knee corresponding portion 31 is arranged in the worn state on the front side of the knee and on the slope of the knee. The knee corresponding portion 31 is gradually stretched in the length direction from the pretensioned state in the height direction as the knee bends, so that the tension applied to the knee corresponding portion 31 gradually increases. Therefore, the knee corresponding part 31 shifts from the front side of the knee to the side along the slope of the knee so as to balance the force. As described above, the knee corresponding portion 31 retreats to the side from the most extended portion of the knee along with the knee bending operation, so that it is difficult to hinder the knee bending operation. In addition, a restoring force corresponding to the amount of elongation associated with the pre-tension and the bending operation is applied to the knee corresponding portion 31 in a state where the knee is bent. Therefore, the knee corresponding portion 31 returns to the original position and pulls in the direction of extending the knee in accordance with the extending operation of the knee, so that the extending operation of the knee can be promoted.

  Moreover, in the said embodiment, the inner center highly rigid part 3a and the outer center highly rigid part 3b are arrange | positioned so that it may space apart on the up-and-down both sides in a length direction. Therefore, the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b are easily slid in directions away from each other on the upper and lower sides in the length direction along with the knee bending operation, and the knee bending operation is difficult to be hindered.

  In the above embodiment, the upper high rigidity portion 6 is connected to the upper anchor 4, the lower high rigidity portion 7 is connected to the lower anchor 5, and the upper high rigidity portion 6 and the lower high rigidity portion 7 are connected to the knee. The rigidity of the corresponding portion 31 is higher than that of the corresponding portion 31. That is, the central high-rigidity portion 3 having a relatively low rigidity is disposed in the portion that extends most during the knee bending operation, and the upper and high-rigidity portions 6 and the lower portion having relatively high rigidity are disposed in the portion having a relatively small elongation. A highly rigid portion 7 is disposed. Therefore, when the knee is bent, the upper high-rigidity portion 6 and the lower high-rigidity portion 7 hardly extend, and the upper high-rigidity portion 6 and the lower high-rigidity portion 7 exhibit an anchor effect, so that the central high-rigidity portion 3 Can be preferentially stretched. Thus, the knee-worn body 1 having the above-described configuration can apply a restoring force to the central high-rigidity portion 3 by preferentially extending the central high-rigidity portion 3, so that the central high-rigidity portion 3, Compared with the case where the upper high-rigidity portion 6 and the lower high-rigidity portion 7 have the same rigidity, the effect of promoting the knee extension operation is high.

  In this case, the rigidity of the upper high-rigidity portion 6 and the lower high-rigidity portion 7 is 1.1 times or more and 120 times or less than the rigidity of the central high-rigidity portion 3. Since the central high-rigidity portion 3 and the lower high-rigidity portion 7 have sufficiently high rigidity with respect to the central high-rigidity portion 3, the upper high-rigidity portion 6 and the lower high-rigidity portion 7 are made difficult to extend, and the central high-rigidity portion 3 The effect of preferentially extending can be improved.

  In the above embodiment, the inner thigh corresponding portion 32a is disposed so as to pass over the inner vastus bulged portion that is the raised portion of the thigh muscle, and the outer thigh compliant portion 32b is the outer vastus ridge that is the raised portion of the thigh muscle. It is arranged so that it passes over the part. With this arrangement, the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b are stretched between the raised portion and the knee while the knee is extended, and the adhesion with the knee is reduced. Therefore, the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b are easily slid from the front side of the knee toward the side along with the knee bending operation.

  Moreover, in the said embodiment, the lower anchor 5 is comprised so that a foot sole can be latched. Therefore, the lower end side of the central high-rigidity part 3 can be firmly fixed with respect to the wearer, so that the central high-rigidity part 3 can be prevented from shifting in the length direction.

  Moreover, in the said embodiment, the upper high-rigidity part 6, the central high-rigidity part 3, and the lower high-rigidity part 7 are comprised by the same fabric (one sheet | seat), The width | variety of the central high-rigidity part 3 is It is formed thinner than the upper high-rigidity portion 6 and the lower high-rigidity portion 7. Therefore, the central high-rigidity portion 3 is formed to be thinner than the upper high-rigidity portion 6 and the lower high-rigidity portion 7, and the rigidity of the central high-rigidity portion 3 is made higher than the rigidity of the upper high-rigidity portion 6 and the lower high-rigidity portion 7. Since it can be made low, a low-rigidity part can be formed easily.

  Moreover, in the said embodiment, the center high-rigidity part 3 is arrange | positioned so that at least the knee corresponding | compatible part 31 may be in a non-connecting state with respect to the body cloth 2. FIG. Therefore, since the knee corresponding portion 31 is easily slid with respect to the body cloth 2 during the knee bending operation, the central high-rigidity portion 3 is easily displaced to the side of the knee.

  In the above embodiment, the inner crus corresponding part 33 a and the outer crus corresponding part 33 b are connected to the connecting part 70. According to this arrangement, the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b are in a state of being constrained to each other on the other side, and approach each other with the connecting portion 70 as a center, and are separated from each other. Therefore, even if the knee bending operation and the extending operation are repeated, the positional relationship between the inner central high-rigidity portion 3a and the outer central high-rigidity portion 3b is unlikely to change, so that the running operation can be performed stably.

  In addition, the knee wearing body 1 of this invention is not limited to the said embodiment, Of course, a various change can be added in the range which does not deviate from the summary of this invention.

  In the said embodiment, although demonstrated as invention of the knee-wearing body 1, it can also be grasped as a wearing method of the knee-wearing body 1. That is, the method of wearing the knee-worn body 1 according to the present invention has one or more central high-rigidity portions 3 that have rigidity higher than that of the body cloth 2 and extend in the length direction.
