Description

Socks and manufacturing method thereof

The present invention aims at prevention, treatment, and correction of ankle joint disorders, and in order to prevent lower limb alignment abnormalities and lower limb disorders caused by bone linkages caused by abnormal movements within the ankle joint, guiding the ribs forward Further, the present invention relates to a sock that smoothly guides the talus to the rear and is suitable for preventing abnormal ankle abduction.

Conventionally, many lower body obstacles due to sports, etc., are abnormalities in which the ankle joint is abducted, that is, the long axis of the foot is facing outward relative to the anteroposterior axis of the tibia when the foot is bent back against the lower limb It is said to be due to exercise. This appears as a skeletal abnormal movement of “knee-in toe-out” (FIG. 1) and is regarded as a dynamic alignment abnormality. There is also an abnormal skeletal movement (Fig. 2) called "knee-out toe-in" (the knees are outward and the toes are inward).

The former is the most common, and more than 85% of humans are said to be unconscious. The disorder caused by the habit of abnormal movement is called “toe-out syndrome” in the field of sports disorders, and the bone chain from the femur to the tibia 104, the rib 105, the talus 106, the rib 107 and the foot (see FIG. 4) Widely induce abnormal movement of the lower body, and more than 80% of lower body disorders are considered to be involved in this abnormal movement.

Here, the abnormal movement of the ankle joint will be described in detail. Ideally, the talus 106 should fit properly between the inner heel 109 and the outer heel 110, and the joint surface should be fitted in a stable position (FIG. 4). The limb has a characteristic of strong flexor control, and the triceps surae composed of the gastrocnemius 101 and the soleus 102 is fused to the Achilles tendon 103 and attached to the rib 107 (FIG. 3). The action of pulling 107 to the back of the body works, and in the standing state, the rib 107 is always guided to the back of the body, and at the same time, the talus 106 slides to the front of the body (FIG. 5).

Next, the abnormal movement during dorsiflexion in the ankle joint will be described. When knee flexion (during dorsiflexion), the action of pulling the rib 107 backward works more than the standing position, and the rib 107 is posterior to the body. At the same time, the talus 106 slides forward of the body (FIG. 5).

Therefore, even when the knee is flexed or standing, the scaphoid bone 108 and the like descend and cause the foot arch to collapse. If the ankle is bent further in an abnormal state, the tibia 104 and the talus 106 displaced forwardly interfere with each other (FIG. 5, broken line portion K), so that the knee is unconsciously escaped inward to avoid interference. To exercise. This is the aforementioned dynamic alignment abnormality “knee-in toe-out” (FIG. 1).

If abnormal movement of the lower body becomes a habit, lower leg alignment abnormalities will occur, body axis misalignment, flat feet, pronation legs, supination legs, O-leg (varus knee), X-leg (valgus knee), hallux valgus, etc. Triggers. Furthermore, it also contributes to induce disorders such as low back pain, hip arthritis, thin splint, Achilles tendonitis, plantar fasciitis, and ankle sprain. From the above, it can be said that the cause of the above-mentioned various disorders is “guidance of the ribs toward the back of the body”.

If this condition is left unattended, it will take a long period of time for improvement and recovery due to a vicious circle of chronic pain, increased recurrence of disability, reduced recovery ability, joint deformation, and reduced competition ability.

Conventionally, there are various taping techniques aimed at fixing joints at each abnormal location as treatments for preventing, treating, and correcting the above-mentioned various disorders. For example, it is a taping technique for fixing each joint such as an ankle, knee or waist where a disorder has occurred.

On the other hand, taking into account the flat foot that is one symptom caused by the above-mentioned abnormal alignment of the lower limbs, in consideration of securing the arch structure of the sole, socks with a convex part formed on the inner surface of the sock bottom along the normal arch of the sole are proposed (For example, see Patent Document 1).
JP 2001-258928 A

However, in the taping technique, there is no opinion or technique that focuses on the cause of the various disorders in the “guidance of the ribs to the back of the body”, but just fixing the joints at each abnormal place by taping. Because it was not too much, it did not lead to the fundamental problem of solving the “guidance of the ribs behind the body”. Since each joint is fixed and its movement is restricted, the range of motion of the joint is restricted, so that there is a problem that sufficient exercise ability cannot be exhibited. In addition to the troublesome taping measures and the fact that effective taping measures can only be expected by a certain level of skill, there is an economic reason that the tape used is disposable. In fact, it is not used much in light sports practice and daily life. However, in order to prevent ankle damage, it is preferable to take some preventive measures.

In addition, the invention according to Patent Document 1 has normal unevenness on the sole by forming a convex part on the inner surface of the bottom of the sock along the original normal horizontal arch and vertical arch, or along either one of the arches. However, depending on the configuration, it is not possible to expect corrective power to the ankle joint itself because it can only cope with one symptom of flat feet. Absent.

And the above-mentioned lower limb alignment abnormality is a phenomenon in which the ribs are pulled backward because there is no muscle in the lower leg that can antagonize the calf, so in the methods such as strength training and putting sole in the shoe sole Can not be cured fundamentally.

Therefore, the present invention provides for the prevention, treatment, and correction of ankle joint disorders, and in particular, smoothly guiding the ribs forward and guiding the talus backwards when the foot is dorsiflexed. Prevents various abnormalities such as lower limb alignment abnormalities and induced sprints by preventing abnormal rotations and correcting abnormal movements of the lower body induced by the bone chain caused by abnormal movements within the ankle joint. It is an object of the present invention to provide socks that can take preventive measures as much as possible.

In order to solve the above problems, the present invention is configured as follows. That is, the sock according to claim 1 is a sock having a knitted region with different stretch strength on the heel covering the rib protuberance, and is worn as a difficult stretch region knitted into a knitted with strong stretch strength. In some cases, there is provided a heel tightening band formed by connecting the vicinity of the apex of the rib raised portion and the upper part of the talus, and the heel tightening band bisects the knitting of the heel portion.

The sock according to claim 2 is a sock having a knitted region with different stretching strength on the heel part covering the rib protuberance, and is worn as a hardly stretchable region knitted into a knitted with strong stretching strength. At the same time, the heel tightening band formed by connecting the vicinity of the apex of the rib protrusion and the upper part of the talus, the upper tie band formed by connecting the inner and outer heels and the upper part of the talus, and the lower toe side lower end of the rib and the upper part of the talus. The underarm fastening band is provided, and the underarm fastening band is formed by dividing the knitting of the collar part into two.

The method for manufacturing socks according to claim 3 is the method for manufacturing hosiery according to claim 1, wherein the knitting of the heel portion is performed by the heel tightening band. The ankle-side heel portion that is divided into two is knitted as an angle adjustment region of the heel tightening band by reverse knitting and gradual reduction of the stitch, and then the heel tightening band is knitted by forward knitting while inserting strong elastic yarn, As a tightening band angle adjustment region, the heel portion on the toe side is knitted by inverting and increasing the stitches.

Furthermore, the method for manufacturing socks according to claim 4 is the method for manufacturing hosiery according to claim 2, wherein the knitting of the heel portion is inserted with a strong elastic yarn. While knitting a heel upper tightening band by forward knitting, the heel part on the ankle side divided by the heel tightening band is knitted as an angle adjustment region of the heel tightening body by reversing knitting and decreasing stitches, and then strong While inserting the elastic yarn, knitting the heel tightening band by forward knitting, and knitting the heel portion on the toe side as the angle adjustment area of the heel tightening band by increasing the reverse knitting and stitches, then inserting the strong elastic yarn It is characterized by knitting the armpit fastening band by forward knitting.

If the socks according to claim 1 are worn, the ribs are pulled forward by the strong contraction force of the bandage band, and the talus and ribs can be guided to appropriate positions, and abnormalities in the ankle joint Can normalize exercise.

Further, according to the socks according to claim 2, due to the strong contraction force of the upper heel band and the lower heel band, the heel band connects the vicinity of the apex of the rib protuberance and the upper part of the talus during intense exercise or the like. It is possible to prevent deviation from an appropriate position.

By normalizing abnormal movement in the ankle joint in this way, the abnormal movement of the lower body induced by the bone chain is also eliminated. As a result, the displacement of the body axis, flat foot, pronation foot, supination foot Alignment abnormalities such as, O-leg (varus knee), X-leg (valgus knee), hallux valgus, low back pain, hip arthritis, sprint, Achilles tendonitis, plantar fasciitis, ankle sprain are resolved Will be.

Furthermore, according to the method for manufacturing socks according to claims 3 and 4, the complicated configuration of the buttocks of the socks according to the present invention can be easily knitted using a circular knitting machine.

Here, first, the guiding of the rib 107 and the talus 106 to the normal positions will be described with reference to FIGS. In order to prevent, treat, and correct ankle joint disorders, and to prevent lower limb alignment abnormalities and lower limb disorders caused by bone linkage caused by abnormal movement in the ankle joint, the rib 107 is moved backward in the body. It is important to prevent the talus 106 from sliding forward (FIG. 5) and to guide the radius 107 and the talus 106 to their normal positions on a daily basis. As the means, it is effective to apply an external force obliquely upward and forward with respect to the rib 107, and the angle α ′ is in the horizontal direction in terms of the structure of a human standard talcrum joint surface and subtalar joint surface. On the other hand, it is preferable to guide the radius 107 from the vicinity of the distal end of the radius 107 toward the upper portion of the talus 106 with a direction axis β ′ that is about 45 ° to about 55 ° (FIG. 6). As a result, the rib 107 is guided to a normal position in front of the body, and at the same time, the talus 106 slides to a normal position in the back of the body.

Hereinafter, the best mode for realizing the socks of the present invention will be described based on examples.

The socks according to the present invention include short socks, thigh socks (length up to the center of the thigh), over the knee (length above the knee), high socks (length up to almost the knee), three-quarter socks (calf) In addition to various socks such as boots socks (length up to the center of the calf), crew socks (slightly longer than short socks), sneaker socks, and pantyhose or tights. Is included. Hereinafter, as Example 1, it demonstrates using a short sock.

A first embodiment of the present invention will be described with reference to FIGS. 7 is a diagram showing the sock 1 according to the present invention according to the first embodiment, FIG. 8 is a diagram showing the action of force, and FIGS. 9 and 10 are the ankle joints when the sock 1 according to the present invention is worn. It is the figure which showed the effect | action of.

In the figure, 1 is a sock according to the present invention, 20 is a hardly stretchable region, and 30 is an angle adjustment region. Reference numeral 20a denotes a saddle fastening band, 20b a saddle upper fastening band, and 20c a saddle lower fastening band. In addition, 40 is a foot insertion opening, 50 is an ankle portion, 60 is an instep sole, and 70 is a toe portion.

The sock 1 includes a heel tightening band 20a, a heel upper tightening band 20b, and a heel lower tightening band 20c as a hardly stretchable region 20 knitted in a knitted portion having a strong expansion and contraction strength at the heel portion, and between the respective tightening bands. The angle adjustment region 30 is configured (FIG. 7). The other foot insertion port portion 40, ankle portion 50, instep sole portion 60, and toe portion 70 have the same configuration as a normal sock.

The material of the socks 1 may be those used for ordinary socks such as natural yarn and synthetic yarn. For example, cotton, acrylic, hair, nylon, polyester, polyurethane, hemp, polyvinyl chloride, polypropylene, etc., and combinations thereof.

The hardly stretchable area 20 is configured to be hardly stretchable by inserting a strong elastic rubber thread. The heel band 20a connects the vicinity of the distal end of the rib protuberance and the upper part of the talus, the upper band band 20b connects the lower ends of the inner and outer ribs in a substantially horizontal direction, and the lower band band 20c is the tip of the talus. A arch is connected in a substantially vertical direction from the vicinity of the end of the side and is provided around. The knitting of the hardly stretchable region 20 may be performed depending on a material to be used or a knitting method as long as a desired stretch strength can be obtained.

The angle adjustment region 30 is formed in a hook-shaped three-dimensional shape that covers the heel portion, and is appropriately sandwiched between the angle adjustment regions by appropriately changing the number of stitches in the angle adjustment region 30 and the start position of the reverse knitting of the stitches. The braiding angle of the fastening band 20a is adjusted.

As shown in FIG. 8, the heel tightening band 20a is provided by connecting the vicinity of the distal end of the rib bulge and the upper part of the talus, and the direction indicated by the line β connecting the distal end z of the rib and the point y of the upper talus, The direction of the force of the expansion / contraction force generated by the heel fastening band 20a is an angle α. If the angle α is configured to be about 40 degrees to about 60 degrees, it is possible to cope with individual differences in the structure of the talus joint surface and the subtalar joint surface depending on age and sex.

The upper clamp band 20b and the lower clamp band 20c guide the ribs to their normal positions so that the clamp band 20a configured at the angle α does not deviate from the angle α when the wearer moves. The upper and lower sides of the heel fastening band 20a are tightened to stabilize.

When the sock according to the present invention is worn, the rib is in a normal position in the front as a result of receiving a strong contraction force by the rib fastening band 20a of the rib part even in a standing state (FIGS. 9 and 10). At the same time, the talus is guided backward by the sliding movement of the subtalar joint, and fits properly between the inner heel and the outer heel. Since no force acts in any other direction, the mobility of the entire ankle joint is not impaired. Further, in response to the strong contraction force of the upper and

lower fastening bands

20b and 20c knitted above and below the saddle fastening band 20a (FIGS. 9 and 10), the angle adjustment region 30 and the saddle fastening band 20a are displaced. , And stable guidance of the ribs and talus to the normal position becomes possible.

Further, at the time of dorsiflexion, as a result of receiving a further strong contraction force by the rib tightening band 20a applied to the rib part, the rib is guided to a normal position in front, and at the same time, the talus is slid by the slide movement of the subtalar joint. Is guided backwards and fits properly between the inner and outer cages. Since no force acts in any direction other than the direction, the mobility of the entire ankle joint is not impaired. In addition, the angle adjustment region 30 and the collar tightening band 20a are prevented from being displaced by receiving a strong contraction force by the collar upper tightening band 20b and the collar lower tightening band 20c knitted above and below the collar tightening band 20a, and the ribs It is possible to guide to a stable normal position.

As described above, if the socks according to the present invention are worn, the abnormal movement in the ankle joint is normalized, so that various disorders of the ankle joint can be prevented in advance, and the abnormal movement of the lower body induced by the bone chain As a result, the body axis shift, flat foot, pronation foot, supination foot, O-leg (varus knee), X-leg (valgus knee), hallux valgus, low back pain, hip arthritis Various problems such as thin splint, Achilles tendonitis, plantar fasciitis, and ankle sprain are resolved.

A second embodiment of the present invention will be described with reference to FIG. In this embodiment, the sock of the above embodiment is applied to stockings.

FIG. 11 is a diagram showing stockings in the present embodiment. In the figure, 21 indicates a hardly stretchable region, and 31 indicates an angle adjustment region.

That is, the stockings in the present embodiment are stockings having knitted regions with different stretch strengths, and connect the vicinity of the apex of the rib bulge and the upper part of the talus as the hardly stretchable region 21 knitted into a knitted fabric with strong stretch strength. The heel tightening band 21a, the heel upper tightening band 21b formed by connecting the inner and outer heels and the upper part of the talus, and the heel lower tightening band 21c formed by connecting the lower end of the rib toe side and the upper part of the talus are configured. In addition, an angle adjustment region 31 knitted with an inverted knitting is provided between the respective fastening bands.

The stocking material in the present embodiment may be a material usually used for stockings, such as nylon and polyurethane, and the knitting of the hardly stretchable region 21 may be performed depending on the material to be used as long as a desired stretch strength can be obtained. Depending on the method of knitting, it is also possible.

If the stockings in this embodiment are worn, abnormal movements in the ankle joint can be normalized, so that various disorders of the ankle joint can be prevented as in the previous embodiment, and the lower body induced by the bone chain. As a result, abnormal movements of the body axis are offset, such as misalignment of the body axis, flat feet, pronation legs, supination legs, O-leg (varus knee), X-leg (valgus knee), hallux valgus, Various problems such as low back pain, hip arthritis, thin splint, Achilles tendonitis, plantar fasciitis, and ankle sprain are resolved.

Next, the sock manufacturing method according to the first embodiment will be described. FIG. 12 is a schematic diagram of the knitting deployment of the sock 1.

For the production of the sock 1, a circular knitting machine is used in which a plurality of needle beds are provided on the outer peripheral surface of a cylindrical cylinder and the plurality of needles are knitted up and down. First, the foot insertion opening 40 is knitted by forward knitting in which the cylinder is rotated forward. As with normal socks, the foot insertion port 40 is knitted by inserting rubber yarn while weaving the ground yarn and the back yarn in order to prevent displacement from the shin portion. The ankle portion 50 is knitted by forward knitting continuously from the foot insertion opening 40. What is necessary is just to change the knitting width | variety of the ankle part 50 according to various socks.

Next, the upper tie-down band 20b is knitted by forward knitting. At the same time, a strong elastic rubber thread is inserted and knitted to tighten the lower ends of the inner and outer collars in a substantially horizontal direction.

When the knitting of the heel upper tightening band 20b is completed, the lower side A on the instep side of the heel upper tightening band 20b enters a knitting waiting state, and the reverse knitting that repeats the forward and reverse rotation of the cylinder to knit the reverse knitting is performed. Start with only. Then, the angle adjustment region 30 on the ankle side is knitted into a trapezoidal shape while gradually decreasing the stitches.

After that, the heel band 20a is knitted by forward knitting. At the same time, a strong elastic rubber thread is inserted and knitted to tighten the vicinity of the distal end of the rib bulge and the upper part of the talus. At this time, the trapezoidal hypotenuse B formed by reversal knitting and the lower side A of the upper tie-down fastening band 20b in a knitting waiting state and the upper side C of the heel fastening band 20a are sewn together at the start of knitting of the heel fastening band 20a. An angle adjustment region 30 on the ankle side is formed in a semi-cylindrical solid shape covering the heel.

Next, for the angle adjustment region 30 on the toe side, only the sole side is inverted and knitted into a trapezoidal shape by increasing the stitches. For this reason, part D of the lower side of the eyelash tightening band 20a is put into a knitting waiting state by the reverse knitting. Usually, the angle adjustment region 30 on the toe side is configured symmetrically with the angle adjustment region 30 on the ankle side.

After that, the underarm fastening band 20c is knitted by forward knitting. At the same time, a strong elastic rubber thread is inserted and knitted to tighten the vicinity of the tip of the talar toe and between the arches in a substantially vertical direction. At this time, the lower side D of the armpit fastening band 20a waiting to be knitted, the trapezoidal oblique side E formed by the reverse knitting, and the upper side F of the instep side of the armpit fastening band 20c are used to start the knitting of the armpit fastening band 20c. Along with this, the angle adjustment region 30 on the toe side is formed in a semi-cylindrical solid shape covering the heel portion. The ankle-side and toe-side angle adjustment regions 30 that are divided into the heel fastening band 20a exhibit a function of integrally covering the heel portion. Further, by changing the number of stitches in the angle adjustment region 30 or the decreasing or increasing start position of the stitches, the angle of the barb tightening band 20a is adjusted to be about 40 degrees to about 60 degrees with respect to the horizontal direction. If the angle α is configured to be about 40 degrees to about 60 degrees, it is possible to cope with individual differences in the structure of the talus joint surface and the subtalar joint surface depending on age and sex. The sock 1 according to the present invention is characterized in that a heel tightening band 20a is formed in the middle of knitting of the heel part, and the knitting of the heel part is divided into two parts, and the angle adjustment region 30 divided in two is the tie part of the heel tightening band 20a. Adjust and maintain the angle.

Next, the instep sole 60 is knitted by forward knitting. Finally, the toe portion 70 is inverted and knitted only on the sole side, and the stitches are formed in a three-dimensional shape that covers the toes by gradually decreasing and increasing the stitches. And the opening part of the toe part 70 is sewed using the sewing part 80, the discarded thread part 90 is cut, and the manufacture of the sock 1 is completed.

In the sock 1 of the first embodiment, the heel tightening band 20a, the heel upper tightening band 20b, and the heel lower tightening band 20c are provided. However, even if the heel upper tightening band 20b and the heel lower tightening band 20c are not provided, the heel The ribs and talus can be guided only with the configuration of the fastening band 20a, and the effects of the present invention can be achieved. However, in order to prevent the displacement of the heel band 20a during the wearer's intense exercise and to maintain stable guidance of the ribs and talus to the normal position, the upper heel band 20b and the lower heel band 20c. It is best to tighten the upper and lower sides of the heel fastening band 20a. In addition, when the sock 1 constituted only by the heel tightening band 20a is attached, it is also possible to prevent the displacement by tightening the portions corresponding to the heel upper tightening band 20b and the heel lower tightening band 20c with a rubber band or the like. Further, as a method of manufacturing the sock 1 constituted only by the heel tightening band 20a, in the method of manufacturing the sock 1 according to the first embodiment, the heel upper tightening band 20b and the heel lower tightening band 20c are not knitted, but the ankle. The ankle-side angle adjustment region 30 may be knitted continuously to the portion 50, and then the heel portion may be knitted in the order of the heel tightening band 20a, the toe-side angle adjustment region 30, and the instep foot sole 60.

In Examples 1 and 2, it is possible to change the knitting widths of the

saddle fastening bands

20a and 21a, the

upper fastening bands

20b and 21b, and the

lower fastening bands

20c and 21c in accordance with the use application and the body shape. . For example, as a sock for sports, the knitting width of the upper upper tightening band 20b and the lower upper tightening band 20c may be increased in order to further prevent the upper tightening band 20a from shifting.

The present invention can be used industrially, for example, by sock manufacturers and distributors.
