Description

  The present invention relates to a cylindrical supporter for protecting joints and the like, and more particularly, to a cylindrical supporter manufacturing method by circular knitting and a cylindrical supporter.

  In general, various supporters are used to protect joints, tendons, cartilage, and the like, and surrounding muscles. The form of the supporter includes a tape form, a fabric, a tubular form, and the like, but the tubular supporter has features such as being easy to wear on the body, good appearance and good feeling. The cylindrical supporter that protects joints, tendons, cartilage, etc., and surrounding muscles, etc., has a shape corresponding to the mounting part, so that the diameter in the root direction of the body is increased and the diameter in the distal direction of the body is decreased. Etc. are made.

  On the other hand, joints, tendons, cartilages, etc., and the surrounding muscles, etc., have parts with large and small movements. By adopting a configuration in which the non-stretchable portion of the cylindrical supporter protects the joint, muscles and the like can be restricted and protected by being compressed. Moreover, it can be set as the cylindrical supporter with which a body can move easily, improving the protection function of an affected part by protecting the non-expandable part of a cylindrical supporter with respect to affected parts, such as a joint and a muscle. For this reason, in the cylindrical supporter, various configurations in which an expansion / contraction part that expands / contracts according to the movement of the body and a non-expansion / contraction part that protects an affected part such as a joint or muscle have been studied. 2 are known in the literature.

  Patent Document 1 discloses a joint supporter in which a joint portion is formed by bending gently at a joint portion so that the entire shape is substantially “<” shape, and elastic portions are formed by weaving rubber threads in the circumferential direction at both ends. The joint supporter is constituted by heel knitting of socks over substantially half of the joint part, and the inside is substantially rectangular by pearl knitting extending and contracting in the vertical direction over substantially half of the joint part. ing. The cylindrical supporter described in Patent Document 1 is configured to sew a plurality of fabrics having different knitting methods.

  Patent Document 2 includes a cylindrical stretchable portion that stretches in the vertical and horizontal directions and a non-stretchable portion that is knitted into the stretchable portion, and the stretchable portion and the non-stretchable portion have a sub-knitting yarn as a non-stretchable main knitting yarn. While knitting into different knitting structures according to the common knitting yarn to be combined, a common stretchable auxiliary yarn is inserted in the transverse direction for each course, and the non-stretchable portion limits the amount of elongation in the longitudinal direction to be smaller than that of the stretchable portion. The auxiliary thread is described as a supporter in a relaxed state and a tension state in the stretchable part and the non-stretchable part, respectively. From the description of Patent Document 2, it is understood that the auxiliary yarn is in a relaxed state indicates that it is knitted in a zigzag shape, and that the auxiliary yarn is in a tension state indicates that it is knitted in a straight shape. The More specifically, as shown in FIG. 14, the cylindrical supporter described in Patent Document 2 has different combination patterns of the non-stretchable main knitting yarns Y1a, Y1b, Y1c and the sub-knitting yarns Y2a, Y2b. While different knitting structures are knitted between the stretchable part 11 and the non-stretchable part 12, a stretchable auxiliary yarn Y3 is inserted in the lateral direction (circumferential direction) for each course, and the stretchable part 11 is fed with an auxiliary yarn (elastic yarn) Y3. The elastic yarn Y3 is knitted in a zigzag shape in the lateral direction (circumferential direction) and always passed through the loop (the portion through which the loop is passed is designated E). Elastic yarn Y3 by alternately knitting a portion (reference E) where the loop passes (reference E) and a location where the loop does not pass (reference F is designated as reference F). Is in a state of tension. In other words, the cylindrical supporter described in Patent Document 2 is different from the stretchable portion 11 and the non-stretchable portion 12 by changing the combination pattern of superimposing the non-stretchable main knitting yarns Y1a, Y1b, Y1c and the subknitting yarns Y2a, Y2b. While using a complicated manufacturing method of knitting different knitting structures, the stretchable portion 11 creates a relaxed state in which the elastic yarn Y3 has a long path by knitting the stretchable auxiliary yarn Y3 in a zigzag manner without fail through the loop. The non-stretchable portion 12 is configured to create a tension state by shortening the length of the elastic yarn Y3 by knitting the stretchable auxiliary yarn Y3 in a straight shape while thinning the number of times the loop is passed through the loop.

However, the cylindrical supporter described in Patent Document 1 has a configuration in which fabrics having different knitting methods are sewn, so that a seam is formed, and a seam is formed, so that the appearance and wearing feeling are anxious. Depending on the frequency of use and the like, there is a problem in that the suture is pulled at the suture location and the end of the suture is easily pulled out and frayed.
On the other hand, the supporter described in Patent Document 2 has different knitting between the stretchable portion 11 and the non-stretchable portion 12 by making the combination pattern of superimposing the non-stretchable main knitting yarns Y1a, Y1b, Y1c and the sub-knitting yarns Y2a, Y2b different. A complicated manufacturing method of knitting a structure is used, and even if it can be manufactured by a knitting machine, many knitting yarns are overlapped and knitted in a complicated pattern, which requires a lot of manufacturing steps and is difficult to circularly knit. As shown in FIG. 14, in the stretchable part 11, the stitch lengths of the non-stretchable yarns (Y1a, Y1b, Y1c, Y2a, Y2b) are small, and in the non-stretchable part 12, the non-stretchable yarn (Y1a , Y1b, Y1c, Y2a, Y2b) are long in length, whereas in the stretchable part 11, the stretchable yarn (Y3) is zigzag long and the non-stretchable part 12 is stretchable. The yarn (Y3) is straight and short. This is because when the range (area) of the non-stretchable portion 12 is increased, the amount of the non-stretchable yarn (Y1a, Y1b, Y1c, Y2a, Y2b) increases, while the stretchable yarn (Y3) is used. This means that the usage amount is reduced, and the usage amount of the non-stretchable yarn (Y1a, Y1b, Y1c, Y2a, Y2b) and the usage amount of the stretchable yarn (Y3) are complicated by the combination pattern of the knitting structure. Even if it can be manufactured on a knitting machine, it is difficult to judge the replacement time of the non-stretchable yarn (Y1a, Y1b, Y1c, Y2a, Y2b) and the stretchable yarn (Y3). Don't be. In addition, since the stitches appear to be aligned in both the stretchable part 11 and the non-stretchable part 12, it cannot be said that the stretchable part 11 and the non-stretchable part 12 can be clearly distinguished from each other in terms of appearance. It is difficult to distinguish between the stretchable part 11 and the non-stretchable part 12 when the supporter is attached to the body.
In addition, the cylindrical supporter should be easily attached to the body by extending and contracting substantially uniformly in the radial direction. However, as in Patent Document 1, the fabrics having different knitting methods are sewn together. The stretchable portion 11 and the non-stretchable portion 12 can be configured by changing the pattern of overlapping the non-stretchable main knitting yarns Y1a, Y1b, Y1c and the sub-knitting yarns Y2a, Y2b as in Patent Document 2. In the case of a configuration obtained from a complicated manufacturing method of knitting different knitted structures, it is considered difficult to perform substantially uniform expansion and contraction in the radial direction of the cylindrical supporter.

  Accordingly, an object of the present invention is to provide a tubular supporter that is attached to the body to protect joints and the like and expands and contracts substantially uniformly in the radial direction thereof, and an expansion / contraction part that uniformly expands and contracts vertically. By forming a non-stretchable part that limits the degree of expansion and contraction in the vertical direction, the movement of joints and muscles is limited and pressed and held, making it easy to attach to the body and making a durable and reliable cylindrical supporter easy with a circular knitting machine Another object of the present invention is to provide a cylindrical supporter that can be easily manufactured and has a good appearance by making it easy to distinguish the stretchable portion and the non-stretchable portion from the outside.

  The manufacturing method of the cylindrical supporter of the present invention is to form a cylindrical circular knitting structure by weaving stretchable knitting yarns in the circumferential direction while making weft stitches with non-stretchable knitting yarns. In a manufacturing method of a cylindrical supporter that stretches substantially uniformly in the radial direction, the elastic knitting yarn is knitted in a straight shape while keeping the size of the non-elastic elastic stitch small in the cylindrical circumferential direction. The stretchable knitting yarn is knitted in a zigzag shape while forming a stretchable portion that is easily stretchable in the longitudinal direction of the tubular shape, and varying the size of the non-stretchable stitch in the circumferential direction of the tubular shape. Thus, the non-stretchable portion for limiting the degree of stretch in the longitudinal direction of the cylinder is formed by making the thickness of the fabric by these knitting yarns larger than the stretchable portion.

  According to the present invention, the stretchable knitting yarn is knitted in a straight shape while aligning the size of the non-stretchable stitch in the cylindrical circumferential direction to form a stretchable portion, and the stretched knitting yarn is formed in the cylindrical circumferential direction. A knitting method in which the stretchable knitting yarns are knitted in a zigzag shape while varying the size of the non-stretchable stitches, and the thickness of the fabric by these knitting yarns is made larger than the stretchable portions to form the non-stretchable portions. Therefore, the knitting yarns can be circularly knitted in a more natural state. Here, the size of the stitches represents the relative relationship in the cylindrical supporter, the stitches are small in the stretchable part, and the stitches are large and small in the non-stretchable part. It is mixed. That is, the stretchable portion is a combination in which the size (length) of the non-stretchable yarn is aligned to be small and the stretchable knitting yarn is straight, and the non-stretchable portion is the non-stretchable stitch. A combination of a large size and a small size in which the stretchable knitting yarn becomes zigzag and the thickness of the fabric by the knitting yarn is larger than the stretchable portion, the range of the non-stretchable portion ( When the area is increased, the amount of the non-stretchable yarn used is increased, and the amount of the stretchable yarn is increased. Naturally, when the range (area) of the stretchable portion is increased, the usage amount of the non-stretchable yarn is reduced, and the usage amount of the stretchable yarn is reduced at the same time. According to the production method of the present invention, the amount of use of the non-stretchable yarn and the amount of use of the stretchable yarn work together, so it is easy to determine the replacement time between the non-stretchable yarn and the stretchable yarn, It is easy for one operator to take charge of many knitting machines (such as circular knitting machines).

  The present invention is characterized in that the ratio of the size of the stitches to be different in the non-stretchable part is set to be twice or more, and the stitches are knitted while periodically switching between the large and small stitches.

  In the non-stretchable part, since the thickness of the fabric is larger than that of the stretchable part, the difference between the non-stretchable part and the stretchable part can be easily understood from the appearance and the touch. The difference between the non-stretchable part and the stretchable part becomes clearer from the appearance and the touch by setting the ratio of the size of the stitches to be different in the stretchable part to be twice or more. In addition, the unevenness of the non-stretchable part can be formed conspicuous by setting the ratio of the size of the stitches to be different in the non-stretchable part to 2 times or more. As a specific method for setting a large difference in size of the stitches, for example, a method in which the stitch length is lengthened by periodically resting the needles. Here, if the cycle of resting the needle is too short, the difference in stretch between the non-stretchable portion and the stretchable portion becomes small, and the unevenness of the non-stretchable portion becomes inconspicuous, and the cycle of resting the needle If the length is too long, the non-stretchable knitting yarn and the stretchable knitting yarn are likely to fray. For example, the stitch length is increased by resting the heel needles every two to six cycles. Then, by knitting while switching these large and small stitches periodically, the degree of expansion and contraction in the area of the non-expandable part can be made substantially uniform. In the present invention, it is preferable to form the non-stretchable portion by knitting both the non-stretchable knitting yarn and the stretchable knitting yarn at the same time while periodically resting. A predetermined pattern can be formed not only in the radial direction but also in the length direction. That is, the non-stretchable knitting yarn and the stretchable knitting yarn are regularly knitted at the same time, and it is possible to manufacture a strong cylindrical supporter that looks good and is not easily frayed. When the same number of the non-stretchable knitting yarn and the stretchable knitting yarn are used, the non-stretchable knitting yarn and the stretchable knitting yarn can be knitted in a balanced manner.

  According to the present invention, the non-stretchable knitting yarn and the stretchable knitting yarn are respectively used in the same number of two or more stretchable knitting yarns. The elastic fixing part, the non-expandable part, and the elastic fixing part are continuously knitted in this order.

  According to the present invention, by using two or more non-stretchable knitting yarns and the same number of stretchable knitting yarns, the production efficiency in the circular knitting machine is further increased. And, by fixing the stretchable fixing part by successively weaving the stretchable fixing part, the non-stretchable part, and the stretchable fixing part in this order from the side closer to the body of the cylindrical supporter that is the product, The end of the knitting yarn is arranged on the side of the tubular supporter that is the product of the part far from the body, and when the cylindrical supporter is attached to the body, the limb is not easily caught on the end of the knitting yarn. Since it becomes a structure, the terminal of the said knitting yarn becomes difficult to fray, and the circular knitted cylindrical supporter without a joint can be manufactured in one process.

  Here, a supplementary explanation is that the substantially uniform expansion / contraction in the cylindrical radial direction means that the expansion / contraction degree between an arbitrary position K1 that pulls the cylindrical supporter in the radial direction and another arbitrary position K2. Ratio, i.e., when K1 / K2 is in the range of 0.5 to 2.0, it is assumed that the tube expands and contracts substantially uniformly in the radial direction, and preferably K1 / K2 is 0. Within the range of 7 to 1.3. Further, aligning the size of the non-stretchable stitches in the stretchable portion means that the length of an arbitrary stitch length L1 of the non-stretchable knitting yarn and other optional stitch length L2 in the stretchable portion. When the ratio, that is, L1 / L2 is in the range of 0.6 to 1.7, it is assumed that the non-stretchable stitches have the same size. It is in the range of 7 to 1.4. On the other hand, the size of the non-stretchable stitches in the non-stretchable part is different in size from the arbitrary stitch length L3 of the non-stretchable knitting yarn in the non-stretchable part and other arbitrary stitch lengths. When the ratio of the length to L4, that is, L3 / L4 is 0.5 or less or 2.0 or more, the size of the non-stretchable stitch is different, preferably L3 / L4 is 0.4 or less or 2.5 or more. Moreover, the average value of the stitch length of the non-stretchable knitting yarn in the stretchable part is set to be the same as or shorter than the average value of the stitch length of the non-stretchable knitting yarn in the non-stretchable part. Then, the path of the stretchable knitting yarn (referred to as M1) in the stretchable part is set shorter than the path of the stretchable knitting yarn (referred to as M2) in the non-stretchable part (M1 <M2). That is, M1 / M2 is 0.9 or less, preferably M1 / M2 is 0.7 or less, and more preferably M1 / M2 is 0.5 or less.

  The cylindrical supporter according to the present invention has a cylindrical radial direction by forming a circular circular knitting structure in a circumferential direction by weaving stretchable knitting yarns into weft knitting stitches composed of non-stretchable knitting yarns. In the cylindrical supporter having substantially uniform expansion and contraction, the size of the non-stretchable stitch in the cylindrical circumferential direction is small and constant, and the stretchable knitting yarn is knitted in a straight shape to form the tubular supporter A stretchable portion that is easily stretchable in the longitudinal direction is formed, and the size of the non-stretchable stitch in the cylindrical circumferential direction is large and small, and the stretchable knitting yarn is knitted in a zigzag shape. The thickness of the fabric by these knitting yarns is larger than that of the stretchable part to form a non-stretchable part in which the degree of stretch in the longitudinal direction of the cylinder is restricted, and this non-stretchable part restricts the movement of joints and muscles. It is characterized by pressure protection.

  According to the present invention, the stretchable yarn is knitted in a zigzag shape in a knitting structure in which the sizes of the stitches of the non-stretchable yarn are combined, and the thickness of the fabric by these knitting yarns is larger than that of the stretchable portion. Since the non-stretchable portion that restricts the degree of expansion in the vertical direction of the cylindrical shape is formed, the knitted yarn is knitted in a natural state, and the non-stretchable portion Since the thickness of the fabric is larger than that of the stretchable part, the difference between the non-stretchable part and the stretchable part can be easily understood from the appearance and the touch. For this reason, it becomes a durable cylindrical supporter that has high functionality, good appearance, and is difficult to fray, and restricts the movement of joints and muscles by the non-stretchable part that restricts the degree of elasticity in the longitudinal direction of the cylinder and protects it by pressing It becomes a cylindrical supporter of the composition to do. Here, the vertical direction is referred to as the vertical direction with the side closer to the body of the cylindrical supporter attached to the body as the upward direction and the side far from the body as the downward direction.

  As the non-stretchable knitting yarn, non-stretchable knitting yarn made of rayon, polyester, nylon, acrylic, natural fiber, etc., a knitting yarn composed of these, a twisted knitting yarn, or the like is applied. Further, as the stretchable knitting yarn, stretchable knitting yarn made of polyurethane, elastomer, natural rubber, etc., a knitting yarn combining these, a twisted knitting yarn, or the like is applied.

  The present invention is characterized in that the unevenness knitted in the non-expandable part is larger than the unevenness knitted in the elastic part.

  According to the present invention, since the unevenness of the non-stretchable part is formed to be larger than the unevenness of the stretchable part, it is possible to make a portion that presses a joint or the like stand out, and the unevenness of the non-stretchable part is large or small. A cylindrical supporter that is functionally superior by forming a pattern that causes aesthetics through vision and that the unevenness of the emphasized non-stretchable part restricts and compresses the movement of joints and muscles. It becomes. Preferably, the size of the unevenness knitted in the non-stretchable part is set to be 2.0 times or more larger than the size of the unevenness knitted in the elastic part, so that the portion that presses the joint or the like becomes more prominent. .

  The present invention is characterized in that the upper and lower sides of the non-stretchable portion are connected to a fixed portion around which the stretchable portion circulates, and these fixed portions are bent to form a multiple structure.

  According to the present invention, the upper end and the lower end of the non-stretchable part are connected to the fixed parts that circulate with elasticity, respectively, and the fixed parts are bent to form a multiple structure, thereby The structure is such that local stress is difficult to be applied at the upper and lower boundaries. Further, the periphery of the stretchable part is reinforced by configuring the stretchable part to be surrounded by the non-stretchable part or the stretchable part being surrounded by the non-stretchable part and the fixing part. Therefore, the cylindrical supporter has a stronger structure. As the arrangement of the non-stretchable parts, for example, a pair is formed on the left and right side surfaces and is connected to each other at a middle position of the non-stretchable parts, so that the non-stretchable parts surround the stretchable parts. It becomes a configuration, and a plurality of enclosed stretchable parts are formed, and a plurality of stretchable parts and a plurality of non-stretchable parts are arranged so that the degree of stretch can be different depending on the body part, As well as the feeling of wearing, the functionality of restricting and compressing the movement of joints and muscles will be enhanced.

  According to the manufacturing method of the cylindrical supporter of the present invention, the knitting yarns can be circularly knitted in a more natural state, and when the range (area) of the non-stretchable portion becomes large, the amount of the non-stretchable yarn used And the use amount of the stretchable yarn increases, and the use amount of the non-stretchable yarn and the use amount of the stretchable yarn are interlocked with each other. Therefore, the non-stretchable yarn and the stretchable yarn It is easy to determine the replacement time of the machine, and it is easy for one operator to take charge of many knitting machines (such as circular knitting machines). Further, the non-stretchable knitting yarn and the stretchable knitting yarn are knitted regularly at the same time, so that it is possible to manufacture a strong cylindrical supporter that looks good and hardly frays. By using the same number of the non-stretchable knitting yarn and the stretchable knitting yarn, the non-stretchable knitting yarn and the stretchable knitting yarn can be knitted in a well-balanced manner. By using it, the manufacturing efficiency of the circular knitting machine becomes higher, and a seamless circular knitted cylindrical supporter can be manufactured in one step.

  According to the cylindrical supporter of the present invention, the stretchable yarn is knitted in a zigzag shape into a knitting structure in which the size of the stitches of the non-stretchable yarn is combined, and the thickness of the fabric by these knitting yarns is the stretchable portion. Is a configuration in which a non-stretchable portion that is larger than that restricts the degree of expansion and contraction in the vertical direction of the cylinder is formed, and thus the knitted yarn is knitted in a natural state, In the non-stretchable part, since the thickness of the fabric is larger than that of the stretchable part, the difference between the non-stretchable part and the stretchable part can be easily understood from the appearance and the touch. For this reason, it becomes a durable cylindrical supporter that has high functionality, good appearance, and is difficult to fray, and restricts the movement of joints and muscles by the non-stretchable part that restricts the degree of elasticity in the longitudinal direction of the cylinder and protects it by pressing It becomes a cylindrical supporter of the composition to do. In addition, since the unevenness of the non-stretchable part is formed to be larger than the unevenness of the stretchable part, it is possible to make a portion that presses a joint or the like stand out. In addition, the emphasized unevenness of the non-stretchable part restricts the movement of joints, muscles, and the like and presses it, thereby providing a cylindrical supporter that is functionally superior. And the upper end and the lower end of the non-stretchable part are connected to fixed parts that circulate with elasticity, respectively, and these fixed parts are bent to form a multiple structure, so that the upper and lower boundaries of the non-stretchable part The structure is such that local stress is not easily applied.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

(Embodiment)
FIG. 1 is a perspective view showing a cylindrical supporter 1 to which the present invention is applied, and FIG. 2 is a front view of the cylindrical supporter 1. The present embodiment is a supporter for protecting joints, tendons, cartilage, and the like, and the surrounding muscles. FIGS. 1 to 4 illustrate knee supporters. In the cylindrical supporter 1 of the present embodiment, as a material of the fabric, fibers such as rayon, polyester, nylon, and acrylic and rubber fibers are woven, and these fibers have a multilayer structure.

  The cylindrical supporter 1 of this embodiment is a circular knitting supporter 1 manufactured by a circular knitting machine, and is formed in a cylindrical shape. A circular knitting machine is a machine that knits a fabric into a round and cylindrical shape, and a general circular knitting machine is not shown, but a cylinder having knitting needles arranged at equal intervals on its outer periphery and a disk-like shape on the upper side of the cylinder. A transfer dial is arranged, and the disk-shaped transfer dial is rotated in synchronism with the cylinder to form a cylindrical knitted fabric by knitting movement of these knitting needles.

FIG. 3 is a left side view illustrating the knee supporter 1 of this embodiment, and FIG. 4 is a right side view of the knee supporter 1. The knee supporter 1 has a cylindrical shape corresponding to the shape of the knee in order to improve the wearability to the knee, and substantially expands and contracts in the radial direction of the cylindrical shape.
Elastic fabrics circulate around the cylindrical upper and lower sides, and fixing portions 2 and 3 are formed by folding these fabrics inward and stitching them (FIG. 1 and the like). The stretchable fixing portions 2 and 3 perform uniform expansion and contraction in the cylindrical radial direction and also perform uniform expansion and contraction in the cylindrical longitudinal direction (vertical direction). In order to make the cylindrical supporter 1 have a shape corresponding to the mounting portion, the diameter of the fixing portion 2 attached in the base direction of the body is made larger than the diameter of the fixing portion 3 attached in the distal direction of the body. Etc. are made. And the fixing | fixed parts 2 and 3 to circulate are each folded inward, sewed, and have a durable structure by making it double.

  A non-stretchable portion 4 that restricts the degree of stretch in the cylindrical longitudinal direction is formed at an intermediate position between the stretchable fixing portions 2 and 3 formed above and below the tubular shape. And the upper end of the said non-expandable part 4 is connected with the end of the fixing | fixed part 2, and the lower end of the non-expandable part 4 is connected with the one end of the fixing | fixed part 3 (FIG. 1). According to this embodiment, the non-stretchable part 4 restricts and protects the movement of joints and muscles by pressing them. And the upper and lower ends of the non-stretchable part 4 are connected to the fixed parts 2 and 3 which have been turned around and bent in a stretchable manner to form a multiple structure (double structure). It is difficult for local stress to be applied at the border.

  9 to 13 are structural views illustrating the knitting structure of the circular knitting supporter 1 of this embodiment. The cylindrical supporter 1 of this embodiment includes a non-stretchable knitting yarn (reference numerals 11 and 12) made of rayon, polyester, nylon, acrylic, natural fiber, and the like, and a stretchable knitting made of polyurethane, elastomer, natural rubber, or the like. Yarns (reference numerals 21 and 22) are knitted to form a cylindrical circular knitting structure. For example, the non-stretchable knitting yarn (reference numerals 11 and 12) is nylon, and the stretchable knitting yarn (reference numerals 21 and 22) is polyurethane. The present embodiment is a weft knitting in which stretchable knitting yarns 21 and 22 are knitted for each course while forming unit stitches (loops) with non-stretchable knitting yarns 11 and 12. Although the details of the structure of the knitted structure will be described later, in order to form the non-stretchable portion 4, at least two types of unit stitch lengths of the non-stretchable knitting yarns 11 and 12 may be set. It is necessary to form the non-stretchable portion 4 by knitting while periodically switching the unit stitch lengths, and adjusting the degree of stretch in the cylindrical longitudinal direction (vertical direction) according to the configuration of these knitted structures Yes.

  In the present embodiment, in addition to the fixing portions 2 and 3, a portion denoted by reference numeral 7 is formed by flat knitting (stencil knitting) (see FIG. 9). The portion indicated by reference numeral 7 is inflated to protect the kneecap, and is uniformly expanded and contracted in the cylindrical radial direction and is also uniformly expanded and contracted in the cylindrical longitudinal direction (vertical direction). . Further, the reference numeral 5 is a part where the knee moves greatly, and the reference numeral 9 is a soft part of the knee. Therefore, the elastic knitting yarns 21 and 22 are passed through the non-elastic knitting yarns 11 and 12. The degree of expansion and contraction in the longitudinal direction (vertical direction) of the cylinder is increased by decreasing the frequency (so-called rubber skipping) (see FIG. 10). In order to increase the degree of compression by the supporter, it is preferable that the degree of expansion and contraction in the cylindrical longitudinal direction (vertical direction) is small in the peripheral part of the kneecap. Therefore, at the place above the knee indicated by reference numeral 8, the unit stitch (loop) by the non-stretchable knitting yarns 11 and 12 is made small, and the stretchable knitting yarns 21 and 22 are made non-stretchable knitting yarns 11, 12 is made to be difficult to elongate in a zigzag manner (see FIG. 13). Reference numeral 6 is a small island surrounded by the non-stretchable portion 4 below the knee, and in order to make it difficult to stretch vertically, unit stitches (loops) by the non-stretchable knitting yarns 11 and 12 are periodically formed. While switching, the elastic knitting yarn 21 is knitted through the non-elastic knitting yarns 11 and 12 in a zigzag manner, and the elastic knitting yarn 22 is knitted through the non-elastic knitting yarns 11 and 12 in a straight line. (See FIG. 11). Further, at the lower knee location indicated by reference numeral 4 and the longitudinally elongated location on the left and right side surfaces of the knee (the non-stretchable portion 4), the unit stitch (loop) by the non-stretchable knitting yarns 11 and 12 is periodically switched while being stretched. The knitting yarn 21 is knitted through the non-stretchable knitting yarns 11 and 12 in a zigzag manner, and the elastic knitting yarn 22 is knitted through the non-stretchable knitting yarns 11 and 12 in a zigzag manner. And the stretchable knitting yarn 22 are knitted by passing them straight through the non-stretchable knitting yarns 11 and 12 so as not to stretch vertically (see FIG. 12).

  In the knee supporter 1 of the present embodiment shown in FIG. 3, the stretchable part 5 is surrounded by the non-stretchable part 4 and the fixed part 2 (or the fixed part 3). Then, the non-stretchable part 4 passes so as to divide the stretchable part 5, and when the non-stretchable part 4 is viewed from the back side, it looks like an “H shape” of the alphabet. According to this embodiment, since the circumference | surroundings of the said expansion-contraction parts 5, 9, and 7 will be reinforced, it becomes the cylindrical supporter 1 of a more durable structure. Then, the plurality of stretchable parts 5, 9, 7 and the plurality of non-stretchable parts 6, 4 can be arranged to have different degrees of stretch depending on the body part, and can be attached to the body. Not only the feeling but also the functionality of restricting and compressing the movement of joints and muscles will be enhanced.

  If the knitted fabrics are arranged in the order in which they are easily stretched, the order of reference numerals 5, 9> reference numerals 2, 3, 7> reference numerals 6, 8> reference numeral 4 is obtained. Reference numerals 5 and 9 are set so that the amount of longitudinal elongation is set large by so-called rubber skipping, and reference numeral 4 indicates that the elastic knitting yarn is knitted through a zigzag while periodically switching the unit stitch length of the non-elastic knitting yarn. The non-stretchable portion is formed so that it does not stretch vertically. Since the knitted fabric is folded inward at the locations indicated by reference numerals 2 and 3, it is difficult to stretch longitudinally as much as the overlap of the fabric compared to the single location of reference numeral 7. The amount of elongation is the same when estimated by. Here, for convenience of explanation of the knitted structure, reference numerals 5, 9, and 7 are used as stretchable parts, and reference numerals 2 and 3 formed by folding the fabric of the stretchable part 7 into a double structure are used as fixed parts. Is described as a non-stretchable portion (non-stretchable portion of the present application), and the reference numeral 8 is distinguished as other.

  The structure of the knitting structure of this embodiment will be described below.

  FIG. 9 exemplifies a knitting structure corresponding to reference numerals 2, 3, and 7 that forms the stretchable portion. The non-stretchable knitting yarns 11, 12 have a short unit stitch (loop) length of 1 The basic shape is flat knitting (Tenji knitting), and the elastic knitting yarns 21 and 22 are passed straight through the loop for each course (referred to as E) and when the loop is not passed ( By repeating and weaving E, F, E, F, E... Alternately for each loop, uniform expansion and contraction is achieved in the cylindrical radial direction, and the cylindrical longitudinal direction (up and down) Direction). As a basic form of the knitting structure corresponding to the reference numerals 2, 3 and 7 and forming the stretchable part, there are a rubber knitting and a pearl knitting in addition to the flat knitting.

  FIG. 10 exemplifies a knitting structure corresponding to the reference numerals 5 and 9 and forming the stretchable part. The unit stitches (loops) of the non-stretchable knitting yarns 11 and 12 are short in one type. When the basic shape is flat knitting (Tenji knitting) and the elastic knitting yarns 21 and 22 are passed straight through the loop for each course (referred to as E), the loop does not pass once. The case (referred to as F) is repeated three times, and this is repeated and knitted with E, F, F, F, E, F, F, F, E. The frequency of passing through the knitting yarns 11 and 12 is reduced (so-called rubber skipping is performed) to increase the degree of expansion and contraction in the cylindrical longitudinal direction (vertical direction). The basic form of the knitting structure corresponding to the reference numerals 5 and 9 and forming the stretchable part includes a rubber knitting and a pearl knitting in addition to the flat knitting (stencil knitting).

  FIG. 13 exemplifies another knitting structure corresponding to reference numeral 8, and the non-stretchable knitting yarns 11, 12 have a short unit stitch (loop) length, and one type is used for each course. When the elastic knitting yarn 21 is passed through the loop in a zigzag manner (referred to as E), the case where it does not pass through the loop (referred to as F) is set to 3 times, and this is repeated until E, F , F, F, E, F, F, F, E..., And similarly, the stretchable knitting yarn 22 is passed through the loop in a zigzag manner with different positions where the loop is passed (referred to as E). Is set to 3 times when it does not pass through the loop (referred to as “F”), and this is repeated repeatedly to weave with E, F, F, F, E, F, F, F, E. It is hard to do.

  FIG. 11 exemplifies a knitting structure corresponding to the reference numeral 6 and forming the non-stretchable portion, and unit stitches (loops) formed by the non-stretchable knitting yarns 11 and 12 in order to achieve a medium longitudinal stretch. The two types of small (short) and large (long) are used, and the stretchability is changed for each course while alternately (periodically) switching two loops in the circumferential direction. When the knitting yarn 21 is passed through the loop in a zigzag manner (referred to as E), the case where it does not pass through the loop (referred to as F) is repeated twice, and this is repeated E, F, F , E, F, F, E..., And when the stretchable knitting yarn 22 is passed through the loop with the loop passing through the loop in different positions (referred to as E) and when the loop is not passed (Sign F) alternately for each loop Ri returns E, F, are E, F, by E ... and knitting, the vertical growth of the moderate.

  FIG. 12 exemplifies a knitting structure corresponding to the reference numeral 4 and forming the non-stretchable portion. In order to prevent longitudinal stretching, the unit stitch (loop) by the non-stretchable knitting yarns 11 and 12 is small ( The stretchable knitting yarn 22 for each course, while switching between two continuous loops in the circumferential direction alternately (periodically). Is passed through the loop in a zigzag manner (referred to as symbol E) and not passed through the loop (referred to as reference symbol F) alternately for each loop and knitted into E, F, E, F, E. When the elastic knitting yarn 21 is passed through the loop in a straight shape with different positions (referred to as E), the loop is passed once (referred to as E), and when the loop is not passed through (referred to as F) three times. And repeat this to E, F, , F, E, F, F, F, performed alternately to E ... and knitting, but extending the horizontal has a configuration that does not extend vertically.

  In this embodiment, the part which presses a joint etc. is made conspicuous by setting large and small difference of the unit stitch (loop) length, and forming the unevenness | corrugation of the said non-expandable part 4 largely. As a specific method of setting a large difference between the unit stitch (loop) lengths, for example, a method in which the unit stitch (loop) length is lengthened by periodically resting the needles. If the period of resting the needle is too short, the difference between the non-stretchable part 4 and the other stretch degree becomes small and the unevenness of the non-stretchable part 4 becomes inconspicuous, and if the period of resting the needle is too long Since the non-stretchable knitting yarns 11 and 12 and the stretchable knitting yarns 21 and 22 are likely to fray, for example, the unit stitch (loop) length is reduced by resting the heel needles every two to six cycles. Lengthen. In the present embodiment, the circular knitting machine is knitted continuously in the order of the fixed portion 3, the fixed portion 2, the non-stretchable portion 4, etc., from the side closer to the body of the cylindrical supporter that is the product, The seamless circular knitted tubular supporter 1 is manufactured in one process.

  According to the present embodiment, the elastic yarns 22 (and 21) are all knitted in a straight shape while the sizes of the stitches made of the non-elastic yarn 11 (and 12) in the cylindrical circumferential direction are made small. The stretchable yarn 22 is formed in a zigzag shape while the stretchable portion 7 is formed, and the size of the stitch formed of the non-stretchable yarn 11 (and 12) in the cylindrical circumferential direction is varied. Since the yarn 21 is knitted in a straight shape and the thickness of the fabric by these knitting yarns is larger than that of the stretchable portion 7 to form a non-stretchable portion, the knitting yarns are circularly knitted in a more natural state. Can do. And when the range (area) of the non-stretchable portion becomes large, the thickness of the fabric by these knitting yarns becomes large, and the amount of the non-stretchable yarn 11 (and 12) used increases, along with this, The usage amount 22 (and 21) increases. Naturally, when the range (area) of the stretchable portion is increased, the amount of use of the non-stretchable yarn 11 (and 12) is decreased, and the amount of use of the stretchable yarn 22 (and 21) is decreased. According to the manufacturing method of the present invention, the amount of use of the non-stretchable yarn 11 (and 12) and the amount of use of the stretchable yarn 22 (and 21) are linked, so that the non-stretchable yarn 11 (and 12). ) And the elastic yarn 22 (and 21) can be easily determined, and it is easy for one operator to take charge of a large number of knitting machines (such as circular knitting machines).

  In the non-stretchable part 4, the thickness of the fabric is larger than that of the stretchable part 7, so the difference between the non-stretchable part 4 and the stretchable part 7 can be easily understood from the appearance and the touch. Furthermore, the difference between the non-stretchable portion 4 and the stretchable portion 7 can be further increased in terms of appearance and touch by setting the ratio of the size of the stitches to be different in the non-stretchable portion 4 to be twice or more. It will be clear. Further, the unevenness of the non-stretchable part 4 can be formed conspicuously by setting the ratio of the size of the stitches to be different in the non-stretchable part 4 to be twice or more. In addition, according to the present embodiment, the non-stretchable knitting yarns 11 and 12 and the stretchable knitting yarns 21 and 22 are used in the same number (two each in this embodiment). The elastic knitting yarns 11 and 12 and the elastic knitting yarns 21 and 22 can be knitted in a well-balanced manner. By using two or more of them, the production efficiency of the circular knitting machine becomes higher, and the seamless round A knitted cylindrical supporter can be manufactured in one step.
