Description

  The present invention relates to a bulging shin supporter and a manufacturing method thereof, and more particularly to a bulging shin supporter of girdle, socks, stockings, and tights and a manufacturing method thereof.

Conventionally, mechanical muscle taping typified by a tape manufactured by Kinesio Co., Ltd. is known, as shown in, for example, Patent Document 1, as being useful for preventing and treating a disorder during various exercises. However, such taping depends on the degree of extension at the time of sticking, and thus requires skill, and because it is in close contact with the skin tissue, the degree of freedom is hindered and blood circulation is easily caused.

In addition, as shown in Patent Document 2, the compression-type knee supporter for sports and nursing use is tightened with an attachment or a fastening tool. It was not supposed to be removable.
JP 2003-73913 A

In this respect, various kinds of proposals have been shown that give a sense of oppression and can be easily attached and detached in daily life. However, it is still difficult to attach and detach the one having the upper and lower tightening portions. In addition, if the kneecap is open, the kneecap cannot be supported. And although patent document 3 has an X-shaped hook, since it is comprised by the impregnation of resin, it has a weak compression force. On the other hand, various girdles with supporters have been proposed. However, there is no clear composition or medical effect.

One of the conditions required for the lower leg supporter is to reduce the degree of muscle fatigue when wearing and exercising for a long time. In this regard, there is a prior art disclosed in Patent Document 4 as a supporter for the lower leg that identifies a part of the human body and is effective for the specific part. In this case, a strong surface piece made of an elastic fabric having a hard elastic property is arranged at the specific portion.
Japanese Patent No. 2607769

  The specific part of Patent Document 4 passes through both sides of the gastrocnemius muscle and is part of the soleus muscle and the Achilles tendon. However, muscle fatigue does not occur in tendons, but occurs mainly in various muscle portions that contact nerves and blood vessels. In addition, the boundary part to which the supporter must press is mainly the inner and outer heads of the shallow layer, not the soleus of the intermediate layer, and this point needs to be more clearly defined.

  Further, Patent Document 4 has a description by molding knitting. However, the strong surface piece is a stretchable fabric. Specifically, only a manufacturing example is disclosed in which a strong surface piece made of stretchable fabric is stitched to a supporter. And this stretch fabric is not touched on whether there is a difference in stretch between the vertical direction and the horizontal direction, nor does it disclose a method that can be manufactured in one step.

On the other hand, the applicants of the present invention previously filed Patent Document 5 as a support for a bulge shin manufactured in one step. In Patent Document 5, an X collar-shaped reinforcing part piece is provided at a bulging shin part, and the reinforcing part piece is made of a reinforcing yarn of a partially attached yarn knitting structure, and an X shape is formed in one step by a cut boss knitting structure cut at both ends. It was manufactured.

However, in subsequent studies, it is preferable that the bulge timber supporter for reducing the fatigue level of the lower leg muscles is particularly that of a structure that suppresses longitudinal elongation. For this purpose, a floating knitted or tucked knitted structure is used as the cut boss knitted structure. Since it was found that the combination is preferable, it is up to the present invention. There is Patent Document 6 as a prior art in which a floating knitting structure is combined with this insertion knitting. Patent Document 7 is a prior art in which an insertion knitting is combined with a tack knitting structure.
Registered Utility Model No. 3039099 Registered Utility Model No. 3046511

  Patent document 6 belongs to the applicant of the present invention, and relates to a camisole-type brassiere, in which a floating knitting structure is combined with an insertion knitting to provide a bust-up function. Further, Patent Document 7 is a combination of an insertion knitting and a tuck knitting structure in order to prevent the sock from slipping down. For this purpose, it is not a part of the knitted fabric but is configured around the entire circumference of the tubular knitted fabric. Therefore, there is no prior art in which a partial cut boss knitting structure is combined with a floating knitting structure or a tuck knitting structure.

This type of swollen shin supporter is necessary for those who suffer from edema in the bulging shin during standing work, and for women who wear high heels and strain their legs, in order to further reduce fatigue of leg muscles due to exercise. It is supposed to be. However, in the conventional fastener in which the supporter simply applies a vertical compression force by the insertion thread as a whole, muscle contraction is warped and does not contribute to the reduction of muscle fatigue. In other words, the ideal inflatable shin supporter effectively presses the body surface corresponding to the muscle part of the human body to expand and contract, and performs a taping function without hindering the movement of the muscle. It is desired to have an effect and a massage effect.

  In view of the above circumstances, the present invention provides a supporter for a bulge shin that can perform a taping function without hindering the movement of muscles, and can reduce muscle fatigue by a stretch effect and a massage effect. Let it be an issue.

In order to achieve the above object, the present invention provides a base structure in which the elongation is equal in the longitudinal direction and the lateral direction, and a longitudinal elongation-suppressing structure in which the longitudinal elongation is extremely lower than the lateral elongation. A support for a bulging shin of a tubular knitted fabric, wherein the longitudinal stretch-suppressing tissue passes from the Achilles tendon on the back to the left and right sides of the triceps surae to the base tissue, and on the inside and outside of the medial head of the gastrocnemius A supporter for inflatable shin formed by forming a V-shape at the periphery of the inflated shin part surrounded by two left and right sides extending to the outside of the head and knitting a synthetic structure of a cut boss knitting and a tuck knitting or a floating knitting It constitutes.

Further, in order to achieve the above object, the present invention suppresses the longitudinal elongation of the base structure in which the elongation is equal in the longitudinal direction and the lateral direction and the longitudinal elongation is extremely lower than the lateral elongation. A method of manufacturing a support for a bulging shin of a tubular knitted fabric made of a tissue, wherein the longitudinal stretch suppressing tissue passes from the Achilles tendon on the back to the left and right sides of the triceps surae to the base tissue, and the medial head of the gastrocnemius From a temporary knitting needle, and a cut boss knitting that is formed with a V-shape at the periphery of the bulging shin part surrounded by two left and right sides extending to the inside of the head and the outside of the outer head For swollen shins formed by knitting a synthetic structure with a tuck knitting in which the stitch is formed at the same time by the next yarn supply without escaping the stitch, or a floating knitting in which a specific needle is placed at an inoperative position and the knitting yarn is not supplied This constitutes a supporter manufacturing method.

  The inflatable shin supporter of the present invention performs a taping function without hindering the bending and stretching movements of the lower leg even when worn during exercise, and also has a stress effect and a massage effect, thereby muscular fatigue. Can be reduced.

  The bulge shin supporter of the present invention, when worn, can eliminate bulging shin edema caused by a human-specific stance.

  If the supporter for bulging shin of this invention wears this, the burden on the leg | foot by putting on a female high heel can be reduced.

  Since the supporter for bulging shin of the present invention does not have a fastener, it is not overtightened.

  The bulge shin supporter of the present invention can be manufactured in one step, and can be manufactured easily and inexpensively.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The lower leg of a human body wearing a porter is shown, (A) is a rear view, and (B) is a side view. FIG. 2 is an example of a leg of the present invention, in which (A) is a rear view, (B) is a side view, and (C) is a perspective view seen from the back in a worn state. FIG. 3 is an example of the sock of the present invention, where (A) is a rear view and (B) is a side view. Figure 4 shows a walking at the time of the human body of the lower leg, (b) is a side view of when attached to the ground the heel, (b) is a side view of the time wearing a foot bottom, (c) was kicking in the toe It is a side view at the time. FIG. 5 is a structure diagram showing an example in which the longitudinal stretch suppressing structure is composed of a composite structure of an insertion knitting, a cut boss knitting, and a one-time tack knitting, and an example of the base structure.

  The bulge shin supporter 1 of the present invention is worn to support the lower leg 2 of a human body as shown in FIG. The lower leg 2 of the human body has an inflated shin part 3 on the back surface. The bulging shin part 3 referred to in the present invention refers to the middle layer of the Achilles tendon 4, the left and right sides of the triceps surae 5, the inner side of the inner head 7 that is a part of the shallow gastrocnemius 6, and the shallow layer. It is the site | part enclosed by the right-and-left two places which reach the outer side of the outer side head 8 which is a part of the gastrocnemius 6 of this. Here, the inside of the inner head 7 means the left inner side of the inner head 7 if it is a right foot, and the inner right side of the inner head 7 if it is a left foot. Similarly, the outer side of the outer head 8 means the right outer side of the outer head 8 if it is the right foot, and the outer left side of the outer head 8 if it is the left foot.

  FIG. 2 shows a bulge shin supporter 11 of the present invention made of a legard, and is composed of a tubular knitted fabric. FIG. 3 shows a bulge shin supporter 21 of the present invention made of socks, which is also composed of a tubular knitted fabric. In addition to this, the supporter for the bulge shin of the present invention is also applied as a tightening tissue to lower leg portions such as stockings and tights.

  The bulge shin supporters 11 and 21 are formed with V-shaped longitudinal elongation suppressing tissues S and S ′ at the periphery of the bulge shin portions 13 and 23 on the back surface. The V-shaped starting point of the longitudinal restraining structures S, S ′ is from the ankle portion in the case of the leg 11, and from the heel portion in the case of the socks 21.

  FIG. 4 shows a state in which the lower leg of the human body moves during walking. When the heel of (i) is attached to the ground, the inflated shin part 33 is pulled by the Achilles tendon 34 and is in the most inflated state. When the next (b) plantar is attached, the inflated shin portion 43 is in a slack state. When the tip of (c) is kicked out, the inflated shin portion 53 is pulled by the Achilles tendon 54. In this way, when the human body is walking, the inflated shin portions 33, 43 and 53 repeat expansion and contraction. Therefore, muscle fatigue occurs in the gastrocnemius muscles of the bulging shin portions 33, 43, and 53 mainly composed of the shallow inner and outer heads.

  FIG. 5 is a structural diagram showing an example of a longitudinal stretch suppressing structure and its base structure according to an embodiment of the present invention. The longitudinal elongation suppressing structure of the present invention is composed of a composite structure of a floating knitting and a cut boss knitting. However, the longitudinal elongation suppressing structure in this embodiment is composed of a combined structure of an insertion knitting, a cut boss knitting, and a one-time tack knitting. ing.

  The right half tissue in FIG. 5 is the longitudinal elongation suppressing tissue S1, while the left half tissue shows an example of the base tissue B1. First, the organization of the base organization B1 is organized as follows. In the course C1, 10 to 40 dtex nylon was double covered (DCY) with a plain knitting yarn Y1 made of 20 to 70 dtex nylon twin yarn and a core yarn of 40 to 210 dtex polyurethane. An insertion knitting (lay-in) RI1 in which insertion yarns Y2 are inserted between knitted fabrics every other wale is used. In the course C2, a knitting yarn Y3 obtained by single-covering (SCY) 20-70 dtex nylon to a core yarn 40-210 dtex polyurethane, and a core yarn 40-210 dtex polyurethane, a 10-40 dtex nylon Are inserted every other wal. Here, decitex is, for example, 10 denier × 4 filaments in the case of 10 to 40 decitex.

  And the direction of the longitudinal elongation suppression structure S1 has the following knitting. In the course C1 of the wal W1, partial platting of a cut boss yarn Y5 made of 20 to 70 dtex nylon twin yarn on a plain (flat knitting) yarn Y1 made of 20 to 70 dtex nylon double yarn ( Partially knitted yarn) and cut boss CB1 cut Ct1 at both ends and core yarn 40-210 dtex polyurethane and 10-40 dtex nylon double covered (DCY) insert yarn Y2 every other wal. Inserted between knitted fabrics. In the course C2 of the wale W1, a knitting yarn Y3 obtained by single-covering (SCY) 20-70 dtex nylon to a polyurethane with a core yarn of 40-210 dtex, and a polyurethane with a core yarn of 40-210 dtex, 10-40 dtex. The insert yarn Y4 obtained by double covering (DCY) is inserted between the knitted fabrics every other wal. The partial splicing knitting referred to in the present invention is because the splicing yarn is a cut boss knitting cut at both ends. The cut Ct1 of the cut boss yarn Y5 is performed at both ends of the longitudinal elongation suppressing structure S1.

Further, in the course C1 of the wale W2, a cut boss yarn Y5 made of 20-70 dtex nylon twin yarn is partially plated (partially knitted yarn) with a knitting yarn Y1 made of 20-70 dtex nylon double yarn. Cut boss knitted CB1 cut at both ends and insert yarn Y2 with 10-40 dtex nylon double covered (DCY) into polyurethane of core yarn 40-210 dtex and inserted between knitted fabrics every other wal. ing. The knitting yarn Y1 and the cut boss yarn Y5 do not make a temporary stitch when knitting the course C2, but make a stitch together when the next course C3 is knitted, and hold it together with the previous stitch without letting out the stitch from the knitting needle. When the stitch is formed by the next yarn feeding, the two stitches are passed through simultaneously to draw out the knitting yarn and to make a new tack knitting TC1. That is, the yarn of course C1 is not knitted on course C2. The one-time tack referred to in the present invention means that one course is skipped and tacked. However, at this time, the insertion yarn Y4 of the course C2 is knitted together to the course C3. However, the knitting yarn Y3 is not tucked and does not form a stitch and stops on the course C2. Note that, as described above, the cut boss yarn Y5 is cut Ct1 at both ends of the longitudinal elongation suppressing structure S1 to form a V-shape.

  In this example, the knitting yarn Y1 is a 20-70 dtex nylon double yarn, whereas the knitting yarn Y3 is a single-covering (SCY) 20-70 dtex nylon to a polyurethane having a core yarn of 40-210 dtex. The reason why the yarn is used is that since the knitting yarn Y1 is used for the tack, the longitudinal elongation can be further suppressed. In this way, the longitudinal elongation suppressing structure S1 is configured to extremely suppress elongation by combining the cut boss knitting and the tack knitting.

  FIG. 6 is a structure diagram showing an example of a longitudinal elongation suppressing structure and its base structure according to another embodiment of the present invention. The longitudinal elongation suppressing structure of the present invention is composed of a composite structure of a floating knitting and a cut boss knitting.

First, the organization of the base organization B2 is organized as follows. In the course C11, a plain (flat knitting) yarn Y11 made of 20 to 70 dtex nylon double yarn and a core yarn 40 to 210 dtex polyurethane were double covered (DCY) with 10 to 40 dtex nylon. An insertion knitting (lay-in) RI2 in which insertion yarns Y12 are partially inserted between knitted fabrics every other wal is used. The partial insertion referred to in the present invention is because no insertion thread is inserted into the next course C12 and the next course C13. That is, in the course C12 and the course C13, the knitting is made only of plain (flat knitting) knitting yarns Y13 and Y14 made of nylon double yarn of 20 to 70 dtex. However, in the wale W11 in the present embodiment, the upper repeat is not complete, but the knitting yarn Y11 in the course C14 is a floating knitting in the next course C15.

In the course C12 and the course C13, the knitting yarn Y11 and the cut boss yarn Y15 do not supply the knitting yarn by placing this needle in the inoperative position during knitting of the knitted fabric, and only hold the previous stitch Part of the knitting yarns Y11 and Y15 are floated straight on the back of the knitted fabric and are knitted on the course C14 to form a second floating knitting structure FL2. The second floating knitting structure referred to in the present invention is knitting by floating two courses. At this time, the insertion yarn Y12 of this embodiment does not float, and the ordinary insertion knitting is maintained on the course C11. The knitting yarns Y13 and Y14 can also be SCY yarns. Further, as described above, the cut boss yarn Y15 is cut Ct2 at both ends of the longitudinal elongation suppressing structure S2 to form a V-shape.

  In the case of the present embodiment, the longitudinal elongation suppressing structure S2 extremely suppresses elongation by the cut boss knitting and the second floating knitting.

The stitches are held together with the previous stitches without letting them escape from the knitting needles. At the same time, the stitches are pulled through the stitches to form a two-tack tuck TC5 that creates a new stitch. In the course C44, the insertion yarn Y42 in which 10 to 40 dtex nylon is double covered (DCY) is knitted on the polyurethane of the core yarn 40 to 210 dtex, but the insertion yarn Y42 floats without being knitted on the wale W44. Yes. In the course C45, the knitting yarn Y41 and the cut boss yarn Y45 as a splicing yarn are knitted, and in the course C46, the knitting yarn Y43 is knitted into a flat knitting. In the wale W43 in this embodiment, the upper repeat is not complete, but the knitting yarn Y44 in the course C47 is the first floating knitting in the next course C48.

  In the course C41 of the next wale W44, a cut boss yarn Y45 made of 20-70 dtex nylon twin yarn is partially plated on a knitting yarn Y41 made of 20-70 dtex nylon double yarn, and the next In the course C42, the knitting yarn Y43 is also knitted flat. In the course C43, the knitting yarn Y44 puts the needle in the inoperative position during knitting of the knitted fabric, does not supply the knitting yarn, and simply holds the previous stitch, and this portion of the knitting yarn is transferred to the back of the knitted fabric. Are not knitted on the course C44, but are knitted on the course C45 to form the first floating knitting structure FL5. In the next course C45, the knitting yarn Y41 and the cut boss yarn Y45 of the splicing yarn are not formed in the course C46 and the course C47 together with the knitting yarn Y43. When the next course C48 is knitted, the stitches are combined with the knitting yarn Y44. It is a two-tack tuck version. The knitting yarns Y43 and Y44 may be SCY yarns. Further, as described above, the cut boss yarn Y45 is cut Ct5 at both ends of the longitudinal elongation suppressing structure S5 to form a V-shape.

  In the case of the present embodiment, the longitudinal elongation suppressing structure S4 extremely suppresses the elongation by the synthetic structure of the cut boss knitting, the two first floating knitting and the tack knitting.

  10 to 15 show JIS. It is a graph of the tensile strength-elongation test by the grab method of L1018, and is the result of pulling at a speed of 50 mm / min. In the grab method, since the knitted fabric is gripped and pulled at the intermediate portion, conditions equivalent to those during actual wearing can be reproduced. FIG. 10 is a graph showing the strength and elongation of the knitted fabric knitted with the base structure of Example 1 until the breakage. FIG. 11 is a graph showing the strength and elongation of a knitted fabric knitted with the longitudinal elongation suppressing structure of Example 1 up to the time of breakage. FIG. 12 is a graph showing the strength and elongation of the knitted fabric knitted with the base structure of Example 4 until the breakage. FIG. 13 is a graph showing the strength and elongation of a knitted fabric knitted with the longitudinal elongation suppressing structure of Example 4 until the breakage. FIG. 14 is an enlarged graph of the initial stage of FIG. FIG. 15 is an enlarged graph of the initial stage of FIG.

  The vertical axis of each graph indicates strength (N), and the horizontal axis indicates elongation (%). A curve G1 in FIG. 10 is a result of pulling the knitted fabric in the horizontal direction, and a curve G2 is a result of pulling the knitted fabric in the vertical direction. A curve G3 in FIG. 11 is a result of pulling the knitted fabric in the horizontal direction, and a curve G4 is a result of pulling the knitted fabric in the vertical direction. That is, in the base structure of FIG. 10, the curve in the horizontal direction of G1 is on the top and the curve in the vertical direction of G2 is on the bottom, indicating that it was easier to extend than in the horizontal direction. On the other hand, in the longitudinal elongation suppressing structure of FIG. 11, the curve in the lateral direction of G3 is down, and the curve of G1 is equal to the curve. On the other hand, it can be seen that the vertical curve of G4 is extremely high and suppresses elongation.

  Similarly, a curve G5 in FIG. 12 is a result of pulling the knitted fabric in the horizontal direction, and a curve G6 is a result of pulling the knitted fabric in the vertical direction. A curve G7 in FIG. 13 is a result of pulling the knitted fabric in the horizontal direction, and a curve G8 is a result of pulling the knitted fabric in the vertical direction. That is, in the base structure of FIG. 12, the horizontal curve of G5 is on the top, and the vertical curve of G6 is on the bottom, indicating that it was easier to stretch than in the horizontal direction. On the other hand, in the longitudinal elongation suppressing structure of FIG. 13, the curve in the horizontal direction of G7 is down, and the inclination is the same as the curve of G5. On the other hand, it can be seen that the vertical curve of G8 is extremely high and suppresses elongation.

  The following Table 1 summarizes the results of the strength and elongation at the time of fracture of the above results.

  From Table 1, it can be seen that the tuck knitting example 1 has a stronger structure than the floating knitting example 4. In both cases, the elongation of the base structure is the same in the vertical and horizontal directions. On the other hand, in the longitudinal elongation suppressing structure, the longitudinal elongation is extremely lower than the lateral elongation.

  However, for the inflatable shin supporter of the present invention, the strength and elongation at break are not a problem, and the behavior of the expansion and contraction during normal wearing is a problem. FIG. 4 shows the change of the bulging shin part during walking. For an example of an adult male, we measured the diameter of the swelled shin part when it was walking in the thinnest state and the swelled state. At that time, the measurement was performed by wearing a legard having no V-shape knitted only with the base structure of Example 1. As a result, the diameter of the swollen shin part was 36 cm in the thinnest state and 37.5 cm in the most swollen state. Therefore, the difference was about 4%.

  The curve G1 ′ in FIG. 14 is an initial stage of the result of pulling the knitted fabric in the horizontal direction as in FIG. 10, and the curve G2 ′ is pulled in the vertical direction in the same manner as in FIG. The initial stage of the results is shown. In this case, the strength P1 at the point position where the elongation in the lateral direction G1 ′ is 4% is 2N. The elongation P2 in the longitudinal direction G2 ′ with respect to 2N is a point position of 14%.

  In contrast to FIG. 14 of the above base structure, FIG. 15 of the longitudinal elongation suppressing structure is an initial stage of the result of pulling the knitted fabric in the horizontal direction similarly to FIG. 10, and the curve G4 ′ is the same as FIG. Similarly, the initial stage of the result of pulling the knitted fabric in the longitudinal direction is shown. In this case, assuming that the maximum internal pressure of the bulging shin part is 2N, the elongation point P3 in the transverse direction G3 ′ of the longitudinal elongation suppressing tissue at that time can reach 26%. On the other hand, the elongation point P4 in the longitudinal direction G4 ′ with respect to the strength 2N is suppressed to 8%, and the effect of suppressing the longitudinal elongation is achieved.

  The following Table 2 shows the above results and the results of Example 4 in which the enlarged view is omitted, together with the elongation% at the intermediate region strength 1N.

From the results shown in Table 2, in the longitudinal stretch-suppressing structure, in contrast to the base structure, the longitudinal elongation is suppressed more than the lateral elongation. The effect of Example 1 is remarkable.

  Table 3 below compares the degree of foot fatigue after running for 10 minutes on a long staircase. 5 shows no fatigue, 3 shows no fatigue, and 1 shows fatigue. Comparison was made between 4 items of non-wearing, conventional supporter wear (conventional product), leg wear of Example 1 (Example 1), and leg wear of Example 4 (Example 4). It is a seed.

  From the results in Table 3, it can be seen that when the bulge shin supporter of the present invention is worn, foot fatigue is reduced.

  The inflatable shin supporter of the present invention can be widely used in girdle, socks, stockings, and tights for the purpose of reducing fatigue of the lower leg muscles, eliminating edema, and providing a stretch effect and a massage effect.
