MODE FOR CARRYING OUT INVENTION

Description of Embodiments of the Disclosure

[0029] First, embodiments of the present disclosure are listed for explanation. [0030] [1] A sock comprising: [0031] an anti-slip part on an outside surface of a bottom of a sock to be in contact with a sole of a wearer when the wearer wears the stoking and/or an inside surface that is a reverse-side surface of the outside surface of the bottom of the sock, wherein [0032] the anti-slip part includes a first anti-slip portion formed on the outside and/or inside surface(s) of the bottom of the sock along an orientation of an aponeurosis plantaris.

[0033] An aponeurosis plantaris f1 of a sole shown in FIG. 11(a) is a ligament extending throughout the entire sole and serves to balance foot movements. The anti-slip part of the sock set forth in [1] above includes a first anti-slip portion formed on the outside and/or inside surface(s) of the bottom of the sock along an orientation of the aponeurosis plantaris of the sole. Therefore, the sock set forth in [1] above makes it possible to efficiently transmit a force of a ligament associated with a foot movement when a sock wearer takes exercise. [0034] [2] The sock set forth in claim 1, wherein the anti-slip part further includes a second anti-slip portion formed on the outside and/or inside surface(s) of the bottom of the sock along an orientation of a ligamentum plantare longum of the sole.

[0035] A ligamentum plantare longum f2 of a sole shown in FIG. 11(b) and FIG. 12(a) has a musculus flexor hallucis brevis f3, a musculus adductor hallucis (caput obliquum) f4, a musculus flexor digti minimi brevis f5, a musculus opponens digti minimi f6, a Musculus peronaeus brevis f7 connected thereto (see FIG. 12(b) to (f)), which are fundamental for transmitting the kinetic energy backward when a sole is in contact with the ground during walking and running. These are strongly involved in the configuration and stability of a longitudinal arch of a foot (a plantar arch). The anti-slip part of the sock set forth in [2] further includes a second anti-slip portion formed on the outside and/or inside surface(s) of the bottom of the sock along an orientation of a ligamentum plantare longum of the sole. Due to such a configuration, the thickness of the sock increases by the second anti-slip portion formed so as to overlap a region corresponding to the ligamentum plantare longum on the outside and/or inside surface(s) of the bottom of the sock. Because the increased thickness can have an effect on the plantar arch to be lifted, the stability of longitudinal arch of the foot can be improved. Further, in the sock set forth in [2], a movement of an ahead muscular group can also be improved by improvement in the stability of the longitudinal arch. Thus, the sock set forth in [2] makes it possible to more efficiently transmit to the ground a force of a ligament associated with a foot movement when a sock wearer takes exercise. [0036] [3] The sock set forth in claim 2, wherein a thickness of the second anti-slip portion is larger than a thickness of the first anti-slip portion, or the thickness of the bottom of the sock is larger in a portion having the second anti-slip portion formed thereon than in a periphery of the portion.

[0037] In the case where the sock set forth in [3] has a larger thickness in the second anti-slip portion than in the first anti-slip portion, the effect of lifting up a plantar arch as mentioned above is enhanced, so that a stability of the longitudinal arch of a foot can be further improved. On the other hand, in the case where the sock set forth in [3] in configured such that the thickness of the bottom of the sock is larger in a portion having the second anti-slip portion formed thereon than in a periphery of the portion, the thickness of the portion having the second anti-slip portion formed thereon enhances the effect of lifting up the plantar arch as mentioned above, so that the stability of the longitudinal arch of the foot can be further improved even when the thickness of the second anti-slip portion is the same as the thickness of the first anti-slip portion. Thus, in the sock set forth in [3], the effect of the sock set forth in [2] can be made reliable.

[0038] The sock set forth in any one of [1] through [3], wherein the anti-slip part further includes a third anti-slip portion formed on the outside and/or inside surface(s) of the bottom of the sock along an orientation of a ligamentum metatarsale transversum superficiale of the sole.

[0039] A ligamentum metatarsale transversum superficiale f8 in the sole, which is shown in FIG. 13, is connected to a musculus adductor hallucis (caput transversum) f9 and serves to hold the lateral arch of the foot, which is fundamental to an action of the big toe through the fifth toe. A plurality of the anti-slip portions of the sock set forth in [4] further includes a third anti-slip portion formed on the outside and/or inside surface(s) of the bottom of the sock along an orientation of a ligamentum metatarsale transversum superficiale of the sole. Therefore, in the sock set forth in [4], a repulsive force of the third anti-slip portion causes a force to push up the ligamentum metatarsale transversum superficiale toward the side of a dorsum of foot. As a result, the lateral arch of the foot can be held, and at the same time, all of the toes become more stretchable, so that it becomes possible for the toes to firmly grip the ground. Thus, the sock set forth in [4] makes it possible to more efficiently transmit to the ground a force of a ligament associated with a foot movement when a sock wearer takes exercise.

[0040] The sock set forth in [1] through [4], wherein the anti-slip part further includes a fourth anti-slip portion formed on the outside and/or inside surface(s) of the bottom of the sock in such a way as to sandwich an ossa sesamoidea position corresponding to an ossa sesamoidea of a big toe of the wearer in a front and rear direction of the sock.

[0041] An ossa sesamoidea f10 of a big toe shown in FIG. 14(a) and FIG. 15(a) serves as a pully of a tendon and makes a movement of a joint and a ligament smooth. A plurality of the anti-slip portions of the sock set forth in [5] includes a fourth anti-slip portion formed on the outside and/or inside surface(s) of the bottom of the sock in such a way as to sandwich the ossa sesamoidea position corresponding to the ossa sesamoidea of a big toe of the wearer in a front and rear direction of the sock. Therefore, in the sock set forth in [5], the ossa sesamoidea of the big toe, which is sandwiched by the fourth anti-slip portion in a front and rear direction of the sock, is made firm and plays its role more in an improved manner. For this reason, the sock set forth in [5] makes it possible to more efficiently transmit to the ground a force of a ligament associated with a foot movement when a sock wearer takes exercise. In addition, a preventive effect for inflammation of the ossa sesamoidea can be expected by the sock set forth in [5].

[0042] The sock set forth in any one of [1] through [5], comprising, on the outside and/or inside surface(s) of the bottom of the sock, an anti-slip unformed region having no anti-slip part formed therein in a region corresponding to a plantar arch of the sole.

[0043] As shown in FIG. 16, the plantar arch of the sole is a place where tendons (a musculus flexor digitorum longus f12 and a musculus flexor hallucis longus f13) are crossed. When this place is pressed, a movement of a foot is restricted. The sock set forth in [6] has, on the outside and/or inside surface(s) of the bottom of the sock, an anti-slip unformed region having no anti-slip part formed therein in a region corresponding to a plantar arch of the sole. Therefore, in the sock set forth in [6], due to the anti-slip unformed region, the place where tendons are crossed becomes hardly pressed. Thus, the sock set forth in [4] makes it possible to more efficiently transmit to the ground a force of a ligament associated with a foot movement when a sock wearer takes exercise.

[0044] The sock set forth in any one of [1] through [6], comprising a first taping knitting part formed by taping knitting of a region corresponding to a retinaculum musculorum extensorum inferius pedis and a retinaculum musculorum peroneorum inferius, respectively, of the wearer's foot.

[0045] A retinaculum musculorum extensorum inferius pedis f14 and a retinaculum musculorum peroneorum inferius f15, respectively, of the foot shown in FIG. 17 serve to hang a longitudinal arch of the foot from above. The sock set forth in [7], comprises a first taping knitting part formed by taping knitting of a region corresponding to the retinaculum musculorum extensorum inferius pedis and the retinaculum musculorum peroneorum inferius, respectively, of the wearer's foot. Therefore, in the sock set forth in [7], the retinaculum musculorum extensorum inferius pedis and the retinaculum musculorum peroneorum inferius can be protected by the first taping knitting part to thereby raise the stability of the longitudinal arch of the foot. Thus, the sock set forth in [7] makes it possible to more efficiently transmit to the ground a force of a ligament associated with a foot movement when a sock wearer takes exercise.

[0046] The sock set forth in [7], comprising a second taping knitting part formed by taping knitting and extending from the first taping knitting part, wherein [0047] the second taping knitting part is formed in a region corresponding to a route which extends from the retinaculum musculorum extensorum inferius pedis of the wearer's foot via an upside of a malleolus lateralis of the wearer's foot, winds around an outside of a head of an Achilles tendon of the wearer, and returns to the retinaculum musculorum extensorum inferius pedis via an upside of a medial malleolus of the wearer's foot.

[0048] In most cases, a human ankle joint is inverted and injured when sprained. The sock set forth in [8] includes the second taping knitting part mentioned above in addition to the first taping knitting part. Therefore, in the sock set forth in [8], formation of the longitudinal arch of the foot by the first taping knitting part is promoted, and thus inversion of an ankle joint can be easily prevented. Further, because the second taping knitting part is configured such that the end of the second taping knitting part is placed on the head side a little bit, deflecting from a portion adhered to an Achilles tendon, the motion of the Achilles tendon itself is hardly prevented.

[0049] The sock set forth in any one of [1] through [8], wherein a tiptoe part at a tip of the sock is formed: [0050] in a round-end configuration to cover the wearer's toes all together, including a big toe, a second toe, a third toe, a fourth toe, and a fifth toe; [0051] in a Japanese socks configuration to cover the toes, keeping the big toe apart from a group of the second, third, fourth, and fifth toes; [0052] in a four-pronged configuration to cover the toes, keeping the big toe, the second toe, the third toe, and a group of the fourth and fifth toes apart from one another; or [0053] in a five-toe configuration to cover the toes, keeping the big toe, the second toe, the third toe, the fourth toe, and the fifth toe apart from one another.

[0054] In the sock set forth in [9], when a tiptoe part at a tip of the sock is formed in a round-end configuration to cover the wearer's toes all together, including a big toe, a second toe, a third toe, a fourth toe, and a fifth toe, the heel of the foot extends sufficiently.

[0055] Therefore, in this case, a force of the heel, for example, to walk gripping the ground is efficiently transmitted to the ground, and thus, it can be especially effective in sporting, such as walking, sauntering, running, and so on.

[0056] In the sock set forth in [9], when a tiptoe part at a tip of the sock is formed in a Japanese socks configuration to cover the toes, keeping the big toe apart from a group of the second, third, fourth, and fifth toes, the sock can enhance an adaptability for the sports which need quick motion of the legs. In addition, the sock is helpful for any sports such as table tennis and badminton, mountaineering enjoyed on the uneven grounds, skiing performed while putting pressure on the big toe, and so on.

[0057] As for the sports in particular such as rugby, short distance sprint, and long jump, in which a player is requested to rush forward, there occurs a phenomenon that the fifth toe wearing a normal sock turns out when kicking the grounds. On contrary, in the case of the sock set forth in [9] having a tiptoe part at a tip of the sock formed in a four-pronged configuration to cover the toes, keeping the big toe, the second toe, the third toe, and a group of the fourth and fifth toes apart from one another, the fifth toe is fixed with the fourth toe, and thus the kinetic energy in the longitudinal direction can efficiently be transmitted to the ground. This case, therefore, can enhance the adaptability for the sports in particular such as rugby, short distance sprint, long jump in which a player is requested to rush forward.

[0058] In the sock set forth in [9], when a tiptoe part at a tip of the sock is formed in a five-toe configuration to cover the wearer's toes, keeping the big toe, the second toe, the third toe, the fourth toe, and the fifth toe apart from one another, the sock can transmit the force of the ligament to the ground without discouraging mechanical conduction of the ligament during sporting activities while protecting each toe in the case where stuffiness between the toes, which is likely to happen to a polyhidrosis patient, should be prevented, in the case where the wearer suffers an ingrown nail in the foot nail, and in other cases.

[0059] The sock set forth in [1] through [8], wherein a tiptoe part at a tip of the sock is formed in a round-end configuration to cover the wearer's toes all together, including a big toe, a second toe, a third toe, a fourth toe, and a fifth toe, [0060] the anti-slip part further includes an anti-slip portion for the round-end configuration, the anti-slip portion for the round-end configuration being formed in a single region on the outside and/or inside surface(s) of the bottom of the sock, including all of the regions respectively corresponding to ball portions of the big toe, the second toe, the third toe, the fourth toe, and the fifth toe.

[0061] In the sock set forth in [10], the effect to be brought by forming the tiptoe part at a tip of the sock in the round-end configuration can be enhanced by the anti-slip portion for the round-end configuration.

[0062] The sock set forth in [1] through [8], wherein a tiptoe part at a tip of the sock is formed in a Japanese-socks configuration to cover the wearer's toes, keeping a big toe apart from a group of the second, third, fourth, and fifth toes, [0063] the anti-slip part further includes anti-slip portions for the Japanese socks configuration, the anti-slip portions for the Japanese socks configuration being respectively formed in two regions on the outside and/or inside surface(s) of the bottom of the sock, including a region corresponding to a ball portion of the big toe and a single region including all of the regions respectively corresponding to ball portions of the second toe, the third toe, the fourth toe, and the fifth toe.

[0064] In the sock set forth in [11], the effect to be brought by forming the tiptoe part at a tip of the sock in the Japanese socks configuration can be enhanced by the anti-slip portion for the Japanese socks configuration.

[0065] The sock set forth in [1] through [8], wherein a tiptoe part at a tip of the sock is formed in a four-pronged configuration to cover the wearer's toes, keeping the big toe, the second toe, the third toe, and a group of the fourth and fifth toes apart from one another, [0066] the anti-slip part further includes anti-slip portions for the four-pronged configuration, the anti-slip portions for the four-pronged configuration being respectively formed in four regions on the outside and/or inside surface(s) of the bottom of the sock, including a region corresponding to a ball portion of the big toe, a region corresponding to a ball portion of the second toe, a region corresponding to a ball portion of the third toe, and a single region including regions respectively corresponding to ball portions of the fourth toe and the fifth toe.

[0067] In the sock set forth in [12], the effect to be brought by forming the tiptoe part at a tip of the sock in the four-pronged configuration can be enhanced by the anti-slip portion for the four-pronged configuration.

[0068] The sock set forth in [1] through [8], wherein a tiptoe part at a tip of the sock is formed in a five-toe configuration to cover the wearer's toes, keeping the big toe, the second toe, the third toe, the fourth toe, and the fifth toe apart from one another, [0069] the anti-slip part further includes anti-slip portions for the five-toe configuration, the anti-slip portions for the five-toe configuration being respectively formed in five regions on the outside and/or inside surface(s) of the bottom of the sock, including a region corresponding to a ball portion of the big toe, a region corresponding to a ball portion of the second toe, a region corresponding to a ball portion of the third toe, a region corresponding to a ball portion of the fourth toe, and a region corresponding to a ball portion of the fifth toe.

[0070] In the sock set forth in [13], the effect to be brought by forming the tiptoe part at a tip of the sock in the five-toe configuration can be enhanced by the anti-slip portion for the five-toe configuration.

Details about Embodiments of the Present Disclosure

[0071] Next, embodiments of the sock in accordance with the present disclosure will be described with reference to the drawings. The present disclosure is not limited by exemplification mentioned below. For example, although, hereinafter, the explanation will be made using the sock that has all the above-mentioned configurations in order to simplify the explanation, each configuration can be combined as appropriate.

Embodiment 1

[0072] A sock in accordance with Embodiment 1 will be described with reference to FIGS. 1 through 17. Here, explanation of Embodiment 1 is made defining the tiptop side of a sock 1, the heel side of the sock 1, the width direction of the sock 1, the instep side of the sock 1, the sole side of the sock 1, the plantar arch side of the sock 1, and the opposite side of the inside side respectively as a front of the sock, a rear of the sock, a sock width direction, an upper of the sock, a downside of the sock, an inside of the sock, and an outside of the sock. In the undermentioned exemplification, the explanation is made using the sock 1 to be applied to the right foot of the wearer. As for the configuration of a sock 1 for a left foot of the wearer, it is sufficient to reverse the configuration of the sock 1 for a right foot in the right and left directions. For the sake of smooth understanding, FIGS. 1 and 2 are prepared by projecting an aponeurosis plantaris f1, a ligamentum metatarsale transversum superficiale f8, and an ossa sesamoidea f10 of the big toe, respectively, of the wearer's right foot on the bottom of the sock, i.e. a sock bottom 11 while simplifying those. FIGS. 1 through 3 are shown in an enlarged size in comparison with FIGS. 4 through 10. FIGS. 11 through 17 schematically show various ligaments, bones, muscles, etc. of a person's right foot and can be referenced as needed.

[0073] As exemplified in FIGS. 1 through 10, the sock 1 in accordance with Embodiment 1 has an anti-slip part 12 on both sides, i.e. the outside surface 11o and the inside surface 11i, respectively, of the bottom of the sock, i.e. a sock bottom 11 to be in contact with a sole of a wearer when the wearer wears the stoking.

[0074] An anti-slip part 12 of this kind can be formed by applying an anti-slipping work on the outside surface 110 and the inside surface 11i, respectively, of the sock bottom 11, using an anti-slipping material composed of known polymer material (such as rubber, elastomer, resin, and so on, more specifically silicone rubber, silicone elastomer, and so on). As for the anti-slipping material, a silicone rubber, for example, can be used, however, there is no restriction in material if the material can bring out an anti-slipping function. It is noted that the inside surface Ili is a reverse-side surface of the outside surface 110 of the sock bottom 11. In other words, the outside surface 11o of the sock bottom 11 can be said to be a reverse-side surface of the inside surface 11i of the sock bottom 11. The inside surface 11i can also be said to be a surface with which the sole skin of the sock wearer is in contact.

[0075] As exemplified in FIGS. 1 and 2, the anti-slip part 12 includes a first anti-slip portion 121 formed on the outside surface 11o and/or the inside surface 11i, respectively, of the sock bottom 11 along an orientation of an aponeurosis plantaris f1 of the sole shown in FIG. 11(a).

[0076] Specifically, the first anti-slip portion 121 can be formed by applying the anti-slipping work on the outside surface 110 and the inside surface 11i, respectively, of the sock bottom 11 along an orientation of the aponeurosis plantaris f1. Here, what is meant by along an orientation of the plantar aponeurosis f1 of the sole is to perform the work in such a way as to overlap the aponeurosis plantaris f1 projected on the sock bottom 11, and the work needs not be performed strictly along the shape of the plantar aponeurosis f1. Along an orientation referred to in the following description can be interpreted in the same way. More specifically the first anti-slip portion 121 can be configured to include a plurality of rectangular anti-slip parts 121a for the aponeurosis plantaris, which has a polygonal shape (a square shape in this embodiment), and a plurality of round anti-slip parts 121b for the aponeurosis plantaris, which has a round shape. Because the rectangular anti-slip parts 121a for the aponeurosis plantaris are formed in a rectangular shape, there is an advantage of easily securing the region which overlaps the aponeurosis plantaris f1. Also, because the round anti-slip parts 121b for the aponeurosis plantaris are formed in a round shape (dot-like), there is an advantage of easily preventing a displacement of the sock 1 during exercise performance of the sock wearer.

[0077] The first anti-slip portion 121 may have an anti-slip portion protruding from the aponeurosis plantaris f1 as long as it includes an anti-slip portion arranged in a manner to overlap the aponeurosis plantaris f1. For example, FIGS. 1 and 2 exemplify the rectangular anti-slip part 121a for the aponeurosis plantaris, which overlaps the aponeurosis plantaris f1 on the front side from the middle position in the front and rear direction of the sock and is arranged at a position not deviating from the aponeurosis plantaris f1, and the rectangular anti-slip part 121a for the aponeurosis plantaris, which overlaps the aponeurosis plantaris f1 and is arranged at a position deviating from the aponeurosis plantaris f1.

[0078] Further, FIGS. 1 and 2 exemplify the round anti-slip parts 121b for the plantar aponeurosis, which overlap the plantar aponeurosis f1 on the rear side from the middle position in the front and rear direction of the sock and is arranged at a position not deviating from the plantar aponeurosis f1. FIGS. 1 and 2 show an example in which other than the round anti-slip parts 121b for the aponeurosis plantaris, a plurality of round anti-slip parts 121c positioned outside of the aponeurosis plantaris, which is not overlapped with the aponeurosis plantaris f1, is arranged in the region on the heel side of the sock 1 in such a way as to surround the periphery of the plurality of the round anti-slip parts 121b for the aponeurosis plantaris from the viewpoint of enhancing the anti-slip effect. It is noted that the round anti-slip parts 121c positioned outside of the aponeurosis plantaris can also be arranged in such a way as to extend toward the upper of the sock outside the sock bottom 11, for example, on the backward side of the heel part of the sock 1.

[0079] As exemplified in FIGS. 1 and 2, the anti-slip part 12 may include a second anti-slip portion 122 formed on the outside surface 110 and the inside surface 11i, respectively, of the sock bottom 11 along an orientation of a ligamentum plantare longum f2 of the sole shown in FIG. 11(b) and FIG. 12(a).

[0080] Specifically, the second anti-slip portion 122 can be formed by applying an anti-slipping work on the outside surface 11o and the inside surface 11i, respectively, of the sock bottom 11 along an orientation of a ligamentum plantare longum f2. More specifically, the second anti-slip portion 122 can be formed in a shape similar to that of the contour of the ligamentum plantare longum f2 in such a way as to overlap the region corresponding to the ligamentum plantare longum f2. The second anti-slip portion 122 in Embodiment 1 includes a single anti-slip part.

[0081] As shown in FIG. 12, a musculus flexor hallucis brevis f3, a musculus adductor hallucis (caput obliquum) f4, a musculus flexor digti minimi brevis f5, a musculus opponens digti minimi f6, a musculus peronaeus brevis f7 are connected (adhere) to the ligamentum plantare longum f2, and these are deeply involved in the configuration and stability of a longitudinal arch of a foot (a plantar arch). From the viewpoints of enhancing an effect of lifting the plantar arch by the second anti-slip portion 122 having a considerable thickness and raising the stability of the longitudinal arch of the foot, etc., the thickness of the second anti-slip portion 122 is preferably configured to be larger than a thickness of the first anti-slip portion 121. Nonetheless, the thickness of the second anti-slip portion 122 may be set to the same thickness as the first anti-slip portion 121. In this case, the thickness in the region of the sock bottom 11 having the second anti-slip portion 122 formed is preferably larger than that in the periphery of the abovementioned region of the sock bottom 11. Due to this configuration, in addition to the effect of the thickness in the second anti-slip portion 122, the effect brought by the increase in the thickness of the abovementioned region of the sock bottom 11 having the second anti-slip portion 122 formed can raise the effect of lifting the plantar arch and can improve the stability of the longitudinal arch of the feet even when the thickness of the second anti-slip portion 122 is set to the same as the first anti-slip portion 121. In this case, when the thickness of the second anti-slip portion 122 is set to be larger than that of the first anti-slip portion 121, the abovementioned effect can be further enhanced.

[0082] It is noted that the aponeurosis plantaris f1 and the ligamentum plantare longum f2 projected on the sock bottom 11 are overlapped. In the sock 1 of Embodiment 1, a part of the sock bottom 11 where the second anti-slip portion 122 is to be formed along an orientation of the ligamentum plantare longum f2 within the region corresponding to the aponeurosis plantaris f1 has no first anti-slip portion 121 formed therein but has the second anti-slip portion 122 preferentially formed.

[0083] As exemplified in FIGS. 1 and 2, the anti-slip part 12 may further include a third anti-slip portion 123 formed on the outside surface Ilo and the inside surface 11i, respectively, of the sock bottom 11 along an orientation of a ligamentum metatarsale transversum superficiale f8 of the sole shown in FIG. 13.

[0084] Specifically, the third anti-slip portion 123 can be formed by applying an anti-slipping work on the outside surface 110 and the inside surface 11i, respectively, of the sock bottom 11 along an orientation of the ligamentum metatarsale transversum superficiale f8. It is noted that the ligamentum metatarsale transversum superficiale f8 is connected to the musculus adductor hallucis (caput transversum) f9 as shown in FIG. 13, and these are deeply involved in the configuration and stability of a transverse arch of a foot. More specifically, the third anti-slip portion 123 may be configured to include a plurality of round anti-slip portions 123b for the ligamentum metatarsale transversum superficiale, which have a round shape. The third anti-slip portion 123 has an advantage that the round anti-slip portions 123b for the ligamentum metatarsale transversum superficiale makes it easy to lift the ligamentum metatarsale transversum superficiale f8 by action of repulsive force and to hold the transverse arch even when the direction and angle for holding down the third anti-slip portion 123 by the sole would be varied.

[0085] The round anti-slip portions 123b for the ligamentum metatarsale transversum superficiale can be configured such that the outer diameter becomes smaller from the inside toward the outside of the sock 1 by little and little or in a step-by-step manner. This configuration has an advantage of easily following the orientation of the ligamentum metatarsale transversum superficiale f8. FIGS. 1 and 2 specifically show an example in which the diameter is made smaller on the outside than the inside of the sock 1 under the condition of setting a boundary at around the part corresponding to the base of the third toe in the sock bottom 11. That is, the round anti-slip portions 123b for the ligamentum metatarsale transversum superficiale in FIGS. 1 and 2 is configured such that the outer diameter becomes smaller from the inside toward the outside of the sock 1 in a step-by-step manner (one step here). FIGS. 1 and 2 show an example in which the outer diameter of the round anti-slip portions 123b for the ligamentum metatarsale transversum superficiale has the same diameter as the round anti-slip parts 121b for the plantar aponeuros of the first anti-slip portion 121, however, the sock 1 is not limited to this example.

[0086] It is noted that the plantar aponeurosi f1 and the ligamentum metatarsale transversum superficiale f8 projected on the sock bottom 11 are overlapped. In the sock 1 of Embodiment 1, a part of the sock bottom 11 wherein the third anti-slip portion 123 is to be formed along an orientation of the ligamentum metatarsale transversum superficiale f8 within the region corresponding to the aponeurosis plantaris f1 has no first anti-slip portion 121 formed therein but has the second anti-slip portion 123 preferentially formed.

[0087] As exemplified in FIGS. 1 and 2, the anti-slip part 12 may further include a fourth anti-slip portion 124 formed on the outside surface 110 and the inside surface 11i, respectively, of the sock bottom 11 in such a way as to sandwich an ossa sesamoidea position P corresponding to an ossa sesamoidea f10 (see FIG. 14(a) and FIG. 15(b)) of a big toe of the wearer in a front and rear direction of the sock.

[0088] The fourth anti-slip portion 124 may include a pair of anti-slip portions 1240 for an outside ossa sesamoidea which sandwich an ossa sesamoidea position Po corresponding to an outside ossa sesamoidea f10o of a big toe, which is shown in FIG. 14(a), in a front and rear direction of the sock, and a pair of anti-slip portion 124i for an inside ossa sesamoidea which sandwich an ossa sesamoidea position Pi corresponding to an inside ossa sesamoidea f10i of a big toe, which is shown in FIG. 15(a), in a front and rear direction of the sock. The anti-slip portions 124o for an outside ossa sesamoidea may be arranged in such a way as to overlap regions of the sock bottom 11 which correspond to a ligamentum phalangus-sesamoid lateralis f11o1 and a ligamentum metatarsus-sesamold lateralisa f11o2 respectively shown in FIG. 14(b) and FIG. 14(c). In a similar way, the anti-slip portions 124i for an inside sesamoid bone may be arranged in such a way as to overlap regions of the underside of the sock 11 which correspond to a ligamentum phalangus-sesamoid medialis f11i1 and a ligamentum metatarsus-sesamold medialis f11i1 respectively shown in FIG. 15(b) and FIG. 15(c).

[0089] It is noted that the plantar aponeurosi f1, the ligamentum phalangus-sesamoid lateralis f11o1, the ligamentum metatarsus-sesamold lateralis f11o2, the ligamentum phalangus-sesamoid medialis f11i1 and the ligamentum metatarsus-sesamold medialis f11i2 projected on the sole 11 are overlapped. In the sock 1 of Embodiment 1, a part of the sock bottom 11 wherein the fourth anti-slip portion 124 which sandwiches the ossa sesamoidea position P in the front and rear direction of the sock is to be formed within the region corresponding to the aponeurosis plantaris f1 has no first anti-slip portion 121 formed therein but has the fourth anti-slip portion 124 preferentially formed.

[0090] As exemplified in FIGS. 1 and 2, the sock 1 of Embodiment 1 can be configured to include an anti-slip unformed region 13 having no anti-slip part 12 formed therein in a region corresponding to the plantar arch (arch of the foot), on the outside surface 11o and the inside surface Ili, respectively, of the sock bottom 11.

[0091] The sock 1 may have the anti-slip unformed region 13 partly or entirely in the region corresponding to the plantar arch on the sock bottom 11.

[0092] As exemplified in FIGS. 4 through 10, the sock 1 of Embodiment 1 can be configured to include a first taping knitting part 141 formed by taping knitting of a region corresponding to a retinaculum musculorum extensorum inferius pedis f14 and a retinaculum musculorum peroneorum inferius f15, respectively, of the wearer's foot shown in FIG. 17.

[0093] Here, what is meant by formed by taping knitting is to form the texture of the sock by knitting so as to exhibit a taping effect. The same is applied to the following. The first taping knitting part 141 may form only an instep part of the sock, or may form an end of the instep part so as to be arranged at the sock bottom 11.

[0094] As exemplified in FIGS. 4 through 10, the sock 1 of Embodiment 1 can be configured to include a second taping knitting part 142 formed by taping knitting and extending from the first taping knitting part 141. The second taping knitting part 142 is formed in a region corresponding to a route which extends from the retinaculum musculorum extensorum inferius pedis f14 of the wearer's foot, which is shown in FIG. 17, via an upside of a malleolus lateralis f16o of the wearer's foot, winds around an outside of a head of an Achilles tendon f17 of the wearer, and returns to the retinaculum musculorum extensorum inferius pedis f14 via an upside of a medial malleolus f161i of the wearer's foot. It is noted that the star in FIG. 7 is a sign indicating the position corresponding to the medial malleolus f161i of the wearer's foot, and the star in FIG. 8 is a sign indicating the position corresponding to the malleolus lateralis f16o of the wearer's foot.

[0095] As exemplified in FIGS. 4 through 10, the sock 1 of Embodiment 1 can be configured to include a third taping knitting part 143 formed by taping knitting of a region corresponding to the periphery of the sock 1 in the width direction, that is, the region extending from the instep side of the sock 1 to the reverse side thereof, and from the reverse side of the sock 1 to the instep side thereof. This configuration has an advantage of enhancing the taping effect of the first taping knitting part 141.

[0096] In the sock 1 of Embodiment 1, a tiptoe part 15 at a tip of the sock 1 is formed to cover the wearer's toes all together, including a big toe, a second toe, a third toe, a fourth toe, and a fifth toe as exemplified in FIGS. 1 and 2. Hereinafter, this configuration will be referred to as a round-end configuration. The tiptoe part 15 at a tip of the sock 1 is not limited to the round-end configuration, and may have other configurations such as, for example, a configuration to cover the wearer's toes, keeping a big toe apart from a group of second, third, fourth, and fifth toes, as exemplified in FIG. 3(a). Hereinafter, this configuration will be referred to as a Japanese socks configuration. The tiptoe part 15 at a tip of the sock 1 may have other configurations such as, for example, a configuration to cover the wearer's toes, keeping the big toe, the second toe, the third toe, and a group of the fourth and fifth toes apart from one another as exemplified in FIG. 3(b). Hereinafter, this configuration will be referred to as a four-pronged configuration. The tiptoe part 15 at a tip of the sock 1 may have other configurations such as, for example, a configuration to cover the wearer's toes, keeping the big toe, the second toe, the third toe, the fourth toe, and the fifth toe apart from one another, as exemplified in FIG. 3(c). Hereinafter, this configuration will be referred to as a five-toe configuration.

[0097] In the case of the round-end configuration exemplified in FIGS. 1 and 2, from the viewpoint of enhancing the effect to be brought by the round-end configuration, the anti-slip part 12 preferably includes an anti-slip portion 125 for the round-end configuration, which is formed in a single region on the outside surface 11o and the inside surface 11i, respectively, of the sock bottom 11, including all of the regions respectively corresponding to ball portions of the big toe, the second toe, the third toe, the fourth toe, and the fifth toe.

[0098] In the case of the Japanese socks configuration exemplified in FIG. 3(a), from the viewpoint of enhancing the effect to be brought by the Japanese socks configuration, the anti-slip part 12 preferably includes an anti-slip portions 125a for the Japanese socks configuration, which are formed in two regions on the outside surface Ilo and the inside surface 11i, respectively, of the underside 11 of the sock, including a region corresponding to a ball portion of the big toe and a single region including all of the regions respectively corresponding to ball portions of the second toe, the third toe, the fourth toe, and the fifth toe.

[0099] In the case of the four-pronged configuration exemplified in FIG. 3(b), from the viewpoint of enhancing the effect to be brought by the four-pronged configuration, the anti-slip part 12 preferably includes an anti-slip portions 125b for the four-pronged configuration, which are formed in four regions on the outside surface 11o and the inside surface 11i, respectively, of the sock bottom 11, including a region corresponding to a ball portion of the big toe, a region corresponding to a ball portion of the second toe, a region corresponding to a ball portion of the third toe, and a single region including regions respectively corresponding to ball portions of the fourth toe and the fifth toe.

[0100] In the case of the five-toe configuration exemplified in FIG. 3(c), from the viewpoint of enhancing the effect to be brought by the five-toe configuration, the anti-slip part 12 preferably includes an anti-slip portions 125c for the five-toe configuration, which are formed in five regions on the outside surface Ilo and the inside surface Ili, respectively, of the sock bottom 11, including a region corresponding to a ball portion of the big toe, a region corresponding to a ball portion of the second toe, a region corresponding to a ball portion of the third toe, a region corresponding to a ball portion of the fourth toe, and a region corresponding to a ball portion of the fifth toe.

[0101] It is noted that the sock 1 in accordance with the abovementioned design and specification can be manufactured by the conventionally known methods in combination with each other as appropriate.

(Embodiment 2)

[0102] A sock in accordance with Embodiment 2 will be described. It is noted that among the reference numerals used in Embodiment 2 and subsequent embodiments, the same reference numerals as those used in the above-described embodiment represent the same components and the like as those in the above-described embodiment unless otherwise specified.

[0103] The sock in accordance with Embodiment 2 differs from the sock in accordance with Embodiment 1 in that the sock in accordance with Embodiment 2 includes the anti-slip part 12 on the outside surface 110 of the sock bottom 11 with which the sole of a wearer is in contact when the wearer wears the sock and includes no anti-slip part 12 on the inside surface 11i of the sock bottom 11. In other words, the sock 1 of the abovementioned Embodiment 1 is an example in which the anti-slip parts 12 are provided on both the surfaces, i.e., the outside surface 11o and the inside surface 11i, respectively, of the sock bottom 11. In contrast, the sock 1 of the abovementioned Embodiment 2 is an example in which the abovementioned anti-slip parts 12 is provided only on the outside surface 110 of the sock bottom 11. The other configurations are the same as those in Embodiment 1.

[0104] Although the effects brought by the sock 1 of Embodiment 2 is smaller than the sock 1 of Embodiment 1, a force of a ligament associated with a foot movement when a sock wearer takes exercise can be efficiently transmit to the ground. In addition, because the sock 1 of Embodiment 2 has no anti-slip part 12 on the inside surface Ili of the sock bottom 11, the manufacturability of the sock is improved by the anti-slip part in comparison with the sock of Embodiment 1. Thus, the sock 1 of Embodiment 2 has high productivity and can be made inexpensively. Because the sock 1 of Embodiment 2 has the anti-slip part 12 only on the outside surface 11o of the sock bottom 11, the anti-slip part 12 is advantageously excellent in slip workability in comparison with a sock of Embodiment 3 mentioned below. The other effects are the same in Embodiment 1.

(Embodiment 3)

[0105] A sock in accordance with Embodiment 3 will be described.

[0106] The sock in accordance with Embodiment 3 differs from the sock in accordance with Embodiment 1 in that the sock in accordance with Embodiment 3 includes the anti-slip part 12 on the inside surface 11i of the sock bottom 11 with which the sole of a wearer is in contact when the wearer wears the stoking and includes no anti-slip part 12 on the outside surface 110 of the sock bottom 11. In other words, the sock 1 of the abovementioned Embodiment 1 is an example in which the anti-slip parts 12 are provided on both the surfaces, i.e., the outside surface 11o and the inside surface Ili, respectively, of the sock bottom 11.

[0107] In contrast, the sock 1 of the abovementioned Embodiment 3 is an example in which the abovementioned anti-slip parts 12 is provided only on the inside surface 11i of the sock bottom 11. The other configurations are the same as those in Embodiment 1.

[0108] Although the effects brought by the sock 1 of Embodiment 3 is smaller than the sock 1 of Embodiment 1, a ligament associated with a foot movement when a sock wearer takes exercise can be efficiently transmit to the ground. In addition, because the sock 1 of Embodiment 3 has no anti-slip part 12 on the outside surface 11o of the sock bottom 11, the appearance of the outside surface 110 of the sock bottom 11 can be made the same as a normal sock. The other effects are the same in Embodiment 1.

[0109] The present disclosure is not limited to each embodiment described above, and various modifications can be made within a range not deviating the gist of the disclosure, The configurations shown respectively in the abovementioned embodiments can be optionally combined with each other.
