Description

  The present invention relates to a knee supporter that covers a knee and its periphery.

  Conventionally, a knee supporter covering the knee and its periphery is known. Some of these knee supporters are made of a plurality of knitted fabrics as shown in Patent Document 1.

  The knee supporter disclosed in Patent Document 1 is an X-shape that has a tightening portion for preventing upper and lower slipping, a knee joint plate portion made of a knitted fabric with the weakest pressure, and a clam-shaped X-shape made of a pressure knitted fabric. And a knitted fabric portion of another portion made of a buffer knitted fabric that can be easily bent and stretched at the knee joint.

JP 2007-54126 A

  However, the above-described conventional knee supporter has a technical problem of having an appropriate compression property and allowing the knee to bend and stretch easily without overtightening. No consideration has been given to correcting so-called knee varus (a state like an O-leg), in which the knee of the leg to which weight is applied during walking opens from the inside to the outside.

  The conventional knee supporter has a saddle-shaped X-shaped intersection at the center of the knee, so when the knee flows outward, the knee is pulled inward by the elastic force of the X-shaped part. When it flows inward, the knee can be pulled outward by the elastic force of the X-shaped part, but these two pulling forces cancel out, so the conventional knee supporter is used for correcting knee varus. In this case, the force to pull the knee inward was weak, and it was not possible to correct the knee varus.

  This invention is made | formed in view of this point, The objective is to provide the knee supporter which corrects the varus of a knee and prevents a knee from opening from the inside to the outside at the time of walking. In addition, when the fabric that constitutes the knee supporter for correcting knee varus has cut boss processing, the convex portion formed by the set of cut end portions of the splicing yarn used in the cut boss processing is on the skin contact surface side. Often provided. Therefore, the convex part of the cut boss process may be in direct contact with the skin surface and the comfort may not be good. SUMMARY OF THE INVENTION An object of the present invention is to provide a knee supporter having improved comfort in addition to correcting knee varus.

  The first invention is based on a knee supporter. This knee supporter includes a telescopic cylindrical main body (11) covering the knee and its periphery, and the main body (11) is more elastic than the base (20) and the base (20). A plurality of portions having a low height, and the base portion (20) is formed so as to cover between the plurality of portions, and the plurality of portions are disposed on the inner side (52) of the knee and the main body portion ( 11) a first portion (21) along the axial direction, and a plurality of belt portions arranged so as to avoid the knee patella (57), and the plurality of belt portions are arranged outside the knee (51). A second part (22) that intersects or is connected only with the end part of the second part (22) communicating or adjacent to the first part (21).

  In a second aspect based on the first aspect, the plurality of portions include a third portion (23) disposed on the front side of the knee and facing the inner vastus muscle on the upper side of the knee. .

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the plurality of portions are arranged on the rear side of the knee and a fourth portion (24) facing the inner gastrocnemius on the lower side of the knee. Is included.

Moreover, 4th invention is the axial direction of the circumferential direction belt | band | zone part (25a) in alignment with the circumferential direction of the said main-body part (11), and the said main-body part (11) in any one invention of 1st to 3rd. And a fifth portion (25) having an axial strip (25b) extending along.

  Furthermore, a fifth invention is the invention of any one of the first to fourth inventions, wherein the fabric constituting the knee supporter has a cut boss process, and the knitting is a two-necked knitting added to the fabric constituting the knee supporter. A double knitted fabric with the fabric made of tissue as the outer fabric and the fabric constituting the knee supporter as the lining, and the convex portion formed by the gathering of the cut ends of the splicing yarn used in the cut boss processing The fabric constituting the knee supporter is turned upside down so as to be provided on the opposite side of the contact surface.

  According to the present invention, in the second portion, the ends of the plurality of belt portions are communicated with or adjacent to the first portion located inside the knee, and the plurality of belt portions are crossed or connected only outside the knee. Since it did in this way, the knee can be pulled from the outside to the inside using the contraction force generated in the plurality of belt portions by the extension of the main body when the knee supporter is worn. Further, since the plurality of belt portions are crossed or connected only on the outside of the knee and are not crossed or connected on the inside of the knee, the force for pulling the knee from the inside to the outside does not work. Thereby, unlike the above-mentioned conventional knee supporter, the force which pulls a knee from the outside to the inside can be sufficiently secured.

  As described above, the knee supporter of the present invention can correct the knee varus so that the knee does not open from the inside to the outside during walking.

FIG. 1 is a view showing a knee supporter when worn according to an embodiment of the present invention, in which (a) is a front view and (b) is a rear view. FIG. 2 is an enlarged view showing thread use of the welt portion of the tightening portion of the knee supporter. FIG. 3 is an enlarged view showing the thread use of the fifth part of the main body. FIG. 4 is an enlarged view showing the first part of the main body part, the X-shaped belt part of the second part, and the thread usage of the third and fourth parts. FIG. 5 is an enlarged view showing the thread usage of the U-shaped belt portion of the second portion of the main body portion. FIG. 6 is an enlarged view showing yarn use of the base portion of the main body portion. FIG. 7 is a graph showing the influence of the valgus angle of the knee joint on the patient's walking cycle. FIG. 8 is an enlarged view showing yarn use of the fabric knitted to the welt portion of FIG. FIG. 9 is a diagram showing the cut boss processed portion in FIG. 1 by hatching.

  Hereinafter, a knee supporter according to an embodiment of the present invention will be described in detail with reference to the drawings. This knee supporter is worn by a patient with knee osteoarthritis, for example. In addition, one Embodiment described below is an illustration and this invention is not limited to one Embodiment.

  The pair of knee supporters (10a, 10b) according to one embodiment includes a left leg and a right leg. The left and right legs are symmetrical. Hereinafter, the knee supporter (10a) for the left leg will be described, and the description of the knee supporter (10b) for the right leg will be omitted.

  The knee supporter (10a) of one embodiment includes a cylindrical main body (11) and an annular tightening portion (12, 13) attached over the entire circumference of both end edges in the axial direction of the main body (11). And have. One fastening part (12) is sewn with a stretchable tape material. Nanofibers are organized on the inner surface of the tape material. This nanofiber increases the surface area of the wearer's skin, thereby increasing the frictional resistance of the tape material. The tape material may be coated with silicon instead of nanofibers. Even in the case of silicon coating, the frictional resistance of the tape material can be increased.

  The other tightening portion (13) is provided with a welt portion. For example, the welt section is made up of three stitches, the first course (C1) is knitted with SCY, the second course (C2) is passed through DCY, and the third course (C3) is knitted with SCY. Knit with inlay knitting.

  However, as will be described later, the main body portion (11) has a cut boss knitting structure, so that the convex portion formed by a set of cut end portions of the spliced yarn to be inserted at the time of cut boss processing is skin contact. If it is provided on the surface side, the convex part of the cut boss process is in direct contact with the skin surface, and the comfort is not good. Therefore, when the convex portion of the cut boss process is provided on the opposite side of the skin contact surface, the comfort can be improved. However, when the convex part of the cut boss process appears on the surface, the appearance quality is impaired. In order to improve the comfort and not impair the appearance quality, the double-knitted knitting structure shown in FIG. 8 is added to the bottom of the fastening part (13) on the welt part side shown in FIG. The knitted portion is folded back at the welt portion to form a double knitted fabric with the fabric shown in FIG. 1 as the lining, and the convex portion of the cut boss processing shown by the diagonal lines in FIG. 9 is opposite to the skin contact surface. Turn over the dough shown in FIG. 1 so that it is on the side. As a result, the convex part of the cut boss process does not come into contact with the skin, so that the comfort can be improved, and the convex part of the cut boss process does not appear on the surface, so that the appearance quality is not impaired. In addition, heat insulation can be improved by using a double knitted fabric composed of a front material and a lining material. For example, the first course (C1) can be knitted with SCY, the third course (C3) can be knitted with SCY, and can be knitted with cross knitting.

  However, the position of the knee and its neighboring parts is difficult to understand simply by using a two-knitted knitting structure as the outer material. Accordingly, when a two-necked knitting structure is added under the fastening part (13) on the side of the welt part in FIG. 1, the lower end part of the fastening part (13) is a line-symmetrical center in FIG. When the cut boss machined portion shown in Fig. 2 is folded, the yarn used in the knitted fabric portion of the two-necked knitting structure corresponding to line symmetry with respect to the edge of the cut boss machined part is set to two-neck knitting. It is preferable that the third course (C3) is knitted by SCY and woolly nylon, knitted by cut boss knitting, and knitted by cross knitting. Therefore, the double-knitted knitting structure shown in FIG. 8 is added below the fastening portion (13) on the side of the welt portion shown in FIG. 1, and the knitted portion is folded back at the welt portion to form a surface. The fabric shown in FIG. 1 is turned over so that the fabric shown in FIG. 1 is turned upside down and the convex part of the cut boss process shown by hatching in FIG. 9 is on the opposite side of the skin contact surface. Since the convex part of the cut boss process and the convex part of the cut boss process of the knitted fabric are covered with the knitted fabric and do not appear on the surface, the appearance quality is not impaired. In addition, the cut boss knitting of the knitted fabric has the effect that the knitting pattern is known and the surface appearance is excellent.

  When wearing the knee supporter (10a), if the fastening part (12) on the tape material side is on the upper side and the fastening part (13) on the welt part side is on the lower side, it will accompany the movement of the wearer. The knee supporter (10a) is prevented from slipping down by the upper tightening part (12), and the knee supporter (10a) is prevented from slipping up by the wearer's movement by the lower tightening part (13).

  Here, SCY refers to a yarn obtained by single-covering a woolen nylon yarn or a filament yarn with a polyurethane elastic yarn core yarn. DCY refers to a yarn in which a polyurethane elastic yarn core yarn is double covered with a wooly nylon yarn or a filament yarn. Inlay knitting refers to knitting by inserting polyurethane elastic yarn into a knitted fabric.

  The main body (11) of the knee supporter (10a) has a portion that is easily stretched and a portion that is difficult to stretch. The strength of the stretch force of these parts is reduced by reducing the number of yarns that are aligned and knitted by knitting, increasing the number of knitting yarns from other parts, or partially knitting yarns that are difficult to stretch and knitting with cut boss knitting.

  Here, the cut boss knitting is a collective term for knitting by knitting another yarn into a partial region of the knitted fabric made of the ground yarn when knitting another yarn on the ground yarn. Functionally, there are cases for the purpose of partial reinforcement of the main body (11) and for the design of the main body (11). In the case of one embodiment, the main purpose is to reinforce partial fabric elasticity.

  It is also possible to sew the entire body portion (11) with an easily stretchable warp knitted fabric, apply another fabric to the portion where it is difficult to stretch, and sew from above. In another method, a thick stretchable fabric can be sewn and the strength of the fabric can be weakened by dissolving a portion that is desired to be easily stretched.

  As shown in FIGS. 1 and 2, the main body (11) of the knee supporter (10a) has a base (20) and first to fifth parts (21 to 25). The base part (20) is formed so as to cover between the first to fifth parts (21 to 25). Moreover, the 1st to 5th site | parts (21-25) are formed with the knitted fabric whose stretchability is lower than a base part (20). When the body part (11) is extended when the knee supporter (10a) is worn, the first to fifth parts (21 to 25) have a stronger contraction force than the base part (20). Acts in the vertical direction. Due to this strong contraction force, the first to fifth parts (21 to 25) tighten the knee or its periphery with a stronger force than the base part (20).

  The base part (20) of the main body part (11) is required to have a support force that wraps around the leg while being required to be easily stretched. Furthermore, since it is a knee supporter (10a), when bending the knee joint, On the front side, the fabric needs to stretch, and it must stretch with low stress in order not to slide down. On the other hand, the back side is a knitted structure in which the amount of knitted fabric is reduced at a portion where the fabric is contracted in the vertical direction when the knee joint is bent. When the amount of knitted fabric is large, the knitted fabric overlaps in a bowl shape and a large number of wrinkles are formed in the lateral direction. This wrinkle bites into the skin behind the knee and causes pain. In order to knitting to further reduce the amount of knitted fabric, there are cases where two yarns are knitted together and knitted, and only one yarn is knitted to reduce that portion. Yarn use consists of, for example, three-neck knitting, the first course (C1) is knitted with SCY, the second course (C2) is passed through DCY, the third course (C3) is knitted with SCY, and inlay knitting Organize with.

<First part>
The first part (21) is formed in a belt shape extending straight along the axial direction of the main body (11). The 1st site | part (21) is arrange | positioned inside a wearer's leg. The 1st site | part (21) is formed over the axial direction both ends of a main-body part (11). When the body part (11) is extended when the knee supporter (10a) is worn, the first part (21) is subjected to strong contraction force in the length direction of the first part (21), and the base part It is harder than (20). This stiff first part (21) plays a role of increasing the stability of the inner side (52) of the knee.

  For example, the first part (21) is composed of three knitting yarns. The first course (C1) is knitted with cut boss knitting with SCY and wooly nylon yarns, and the second course (C2). ) Is inserted through DCY, and the third course (C3) is knitted with cut boss knitting and knitting with inlay knitting, using SCY and Woolley nylon yarn as splicing yarn.

<Second part>
The second part (22) is composed of X-shaped and U-shaped strips (22a, 22b). The X-shaped belt portion (22a) is arranged to avoid the knee patella (57). The X-shaped belt portion (22a) is formed by intersecting two belt portions (A1, A2) on the outside (51) of the knee.

  The two belt portions (A1, A2) constituting the X-shaped belt portion (22a) are formed over the front side and the rear side of the leg. One of the two belt portions (A1) has an upper end communicating with the upper portion of the first portion (21) and a lower end adjacent to the lower portion of the first portion (21). The other of the two belt portions (A2) has an upper end adjacent to the third portion (23) and a lower end adjacent to the fourth portion (24). Here, as will be described later, the X-shaped belt portion (22a) is knitted with the same knitted fabric as the third and fourth portions (23, 24). Therefore, the other of the two belt portions (A2) has an upper end substantially adjacent to the upper portion of the first portion (21) through the third portion (23) and a lower end of the fourth portion (4). It is substantially adjacent to the lower part of the first part (21) through (24). Thus, the end of the X-shaped strip (22a) of the second part (22) communicates with or is adjacent to the first part (21).

  The U-shaped belt part (22b) of the second part (22) is arranged so that the knee patella (57) is located inside thereof. The U-shaped belt portion (22b) is configured by connecting two J-shaped belt portions (B1, B2) located on the front side of the knee at the outer side (51) of the knee. Both ends of the U-shaped band (22b) are adjacent to the first part (21).

When the body portion (11) is extended during the wearing of the knee supporter (10a), the contractile force of the X-shaped or U-shaped band part of the second portion (22) (22a, 22b), the knee By pressing from the outside to the inside and pressing the first part (21), it is possible to correct the varus of the knee and prevent the knee from opening from the inside to the outside during walking.

  The yarn used in the X-shaped band (22a) of the second part (22) consists of, for example, a three-necked knitting, and the first course (C1) uses SCY and Woolley nylon yarn as a spliced yarn, and a cut boss The second course (C2) is knitted by knitting, and the third course (C2) is knitted by cut boss knitting and knitted by inlay knitting, with SCY and wooly nylon yarn as splicing yarn.

  The use of the tissue of the U-shaped band (22b) of the second part (22) consists of, for example, three-neck knitting, the first course (C1) is knitted with SCY, and the second course (C2) Is inserted through DCY, and the third course (C3) is knitted with cut boss knitting and inlay knitting with SCY and wooly nylon as splicing yarn.

<Third and fourth parts>
The third and fourth portions (23, 24) are formed in a polygonal shape. The third region (23) is located on the front side of the knee and faces the inner vastus muscles on the upper side of the knee. The fourth region (24) is located on the back side of the knee and faces the medial gastrocnemius muscle below the knee. The third part (23) plays a role of pressing the inner vastus muscles from the front side of the leg and assisting knee extension. The fourth part (24) plays a role of assisting the flexion of the knee by pressing the inner gastrocnemius muscle from the rear side of the leg.
The third and fourth parts (23, 24) are composed of, for example, three-necked knitting, and the first course (C1) is knitted with cut boss knitting with SCY and Woolley nylon yarn as a splicing yarn. The second course (C2) is inserted through DCY, and the third course (C3) is knitted with cut boss knitting and knitted with inlay knitting, using SCY and wooly nylon yarn as splicing yarn.

<5th part>
The fifth part (25) is used for the purpose of strengthening the structure of the upper part and the middle part of the main body part (11). It has the circumferential belt | band | zone part (25a) in alignment with the circumferential direction of a main-body part (11), and the axial direction belt | band | zone part (25b) extended along the axial direction of the said main-body part (11).

  In severe knee arthropathy, the structure is strengthened with a hard material such as metal or resin. However, in the case of an embodiment aimed at protection of mild knee arthropathy or knee joint, from the viewpoint of quality of life, the knee It is necessary to reinforce the structure without affecting the clothes while suppressing the discomfort when wearing the supporter (10a). Therefore, the use of the yarn of the structure of the fifth part (25) consists of, for example, three-neck knitting, and the first course (C1) is knitted with cut boss knitting with SCY and wooly nylon yarn as the additional yarn, and the second course. (C2) is inserted through DCY, and the third course (C3) is knitted with SCY and knitted with inlay knitting.

  In the main body (11), the first part (21), the X-shaped belt part (22a) of the second part (22), the third and fourth parts (23, 24) are the least likely to extend. It is. The fifth part (25) is more easily extended than these. The U-shaped band portion (22b) of the second portion (22) is more easily extended than the fifth portion (25). The base part (20) is the easiest to stretch.

  When the knitted fabric of the supporter according to the human body shape is obtained, the amount of elastic yarn fed is controlled by a fashioning device that changes the structure, a tension device that keeps the release tension constant during yarn feeding, and computer control It is necessary to knit by a knitting machine equipped with a positive yarn feeding device. Further, the structure of the portion that is difficult to stretch in the supporter can be knitted by any knitted fabric structure, for example, flat knitting, mesh knitting, float knitting, tuck knitting, combination of tuck knitting and float knitting, cut boss knitting, or the like. . As an example, a knitting machine manufactured by MERZ, SANTONI, or LONATI is used.

(Test results of examples)
FIG. 7 is a graph showing the influence of the valgus angle of the knee joint on the patient's walking cycle when the knee supporter (10a) of the example is worn and when not worn. A solid line indicates a case where the user walks without wearing the knee supporter (10a), and a broken line indicates a case where the user walks without wearing the knee supporter (10a). The vertical axis represents the valgus angle. When the angle is greater than 0 °, the valgus angle is indicated. When the angle is less than 0 °, the valgus angle is indicated. The horizontal axis indicates the walking cycle. In the figure, the stance phase refers to the time when the leg is in contact with the ground, and the swing phase refers to the time when the leg is away from the ground.

  As can be seen from FIG. 7, when the patient walks without wearing the knee supporter (10a), the knee is varus (state like an O leg) from the early stage to the middle stage of the stance phase. On the other hand, when the patient walks while wearing the knee supporter (10a), the knee is always in a valgus state (like the X leg) throughout the stance phase. From this result, the correction force in the valgus direction of the knee by the knee supporter (10a) is recognized.

  In addition, the maximum amount of movement of the knee joint at the beginning of the stance phase (lateral movement) is 4.97 ° (θi in FIG. 7) on the varus side when the knee supporter (10a) is not worn. When the knee supporter (10a) is worn, the angle is 1.61 ° on the valgus side (θo in FIG. 7). Wearing the knee supporter (10a) reduces the maximum amount of knee joint movement by 78%. From this result, it was found that the knee support stability was improved by the knee supporter (10a).
