Description

  The present invention relates to a sock worn by a person on a foot.

Conventionally, socks having various functions have been proposed.
For example, socks with a correction function have been proposed (see Patent Document 1).
This sock with a corrective function includes a sole that corresponds to the metatarsal ligament and a portion that abuts on both sides thereof with an elastic material, and a portion that abuts on the foot surface corresponding to the metatarsal ligament. Consists of a less elastic material. Thereby, since it does not clamp | tighten from a foot surface part toward a sole part, it is supposed that a metatarsal ligament can be reproduced | regenerated well in desired lateral arch shape. It is also described that a second elastic region is provided in the Achilles tendon portion.
However, the invention of Document 1 is not intended to prevent a fall.

JP 2005-42213 A

  In view of the above-described problems, an object of the present invention is to provide a sock that can be useful for preventing falls and to improve user satisfaction.

According to the present invention, an elastic portion having a stronger force than the other surrounding portions is provided between the back of the Achilles tendon and the inner heel of a human foot and between the back of the Achilles tendon and the outer heel, and the elastic portion includes the Achilles tendon. Provided separately from an inner ferroelastic portion between the back and the inner heel and an outer ferroelastic portion between the Achilles tendon and the outer heel, between the inner ferroelastic portion and the outer ferroelastic portion. The sock is provided with an Achilles tendon release portion on the back of the Achilles tendon that is less elastic or inelastic than the inner strong elastic portion and the outer strong elastic portion .

  According to the present invention, it is possible to provide a sock that can be used for prevention of falling.

The right side view of socks. The partial sectional view which looked at socks from the plane side. The bottom view which looked at socks from the bottom side. The right side sectional view of socks.

  The inventor of the present invention has conducted intensive research so as to prevent a person who falls easily or a person who easily twists his / her foot from falling or twisting his / her foot. As a cause of falling or twisting the foot, walking with the foot tilted inward is grounded from the little ball side of the foot, and the little ball side goes too far inside and turns or falls. Was found to have occurred. In order to improve such a grounding state, it is only necessary to improve so that the sole is grounded in parallel and not from the little ball side.

  Therefore, the inventors examined various sock shapes. And one of the causes is that the socks float away from the body surface from the Achilles tendon to the heel, and when this part of the socks is in contact with the body surface, the walking that was grounded from the little finger ball side is straightened I found out that it would come close to grounding.

  The inventors have invented that by changing the elasticity of the sock between the heel and the Achilles tendon, the sock can be brought into contact with the body surface as much as possible without floating from the body surface between the Achilles tendon and the heel. In addition, the present inventors have invented that the above-described twisting and falling can be further prevented by spreading the toes firmly and grounding to prevent floating fingers.

  Hereinafter, an embodiment of the present invention to which all of these elements are added will be described with reference to the drawings.

  1 shows a right side view of the sock 1 in a state worn by a person, FIG. 2 shows a plan view of the sock 1 crossed in the vicinity of the heel rotated by 180 degrees, and FIG. FIG. 4 is a right side cross-sectional view of the sock 1 that has been cut vertically.

  As shown in FIG. 1, the sock 1 includes an open ring-shaped edge 2, an ankle part 3 connected to the edge part 2, a heel part 9 connected to a bottom surface from a lower back surface of the ankle part 3, and an ankle. The toe part 4 connected from the front side of the part 3 and the heel part 9 and the toe part 5 connected to the tip of the toe part 4 are provided.

The entire sock 1 is formed of a knitted fabric knitted by an appropriate knitting method.
In the rear part between the heel part 9 and the ankle part 3 of the sock 1, there is provided a close-up preventing contact part 20 from the left and right heel K to the rear center where the Achilles tendon back K5 (see FIG. 2) is located. The width L11 (vertical width in FIG. 1) of the fall-preventing adhesion portion 20 can be formed to be 1.5 cm to 5 cm when worn by a person, and can be formed to be 2 cm to 4 cm. In this embodiment, it is formed so as to be a suitable size of about 2.5 cm. A height L12 from the fall-preventing close contact portion 20 to the ground surface is about half lower than the width L11 from the ground surface to the height of the flange K.

  As shown in FIG. 2, the fall-preventing close contact portion 20 includes an inner weak elastic portion 21 extending rearward from the inner collar K1, an inner strong elastic portion 22 extending further to the vicinity of the rear Achilles tendon, and the back of the Achilles tendon continuing from there. It has a partial Achilles tendon release portion 23, an outer strong elastic portion 24 that continues partway from the Achilles tendon release portion 23 toward the outer collar K <b> 2, and an outer weak elastic portion 25 that further continues to the outer collar K <b> 2 therefrom. In front of the inner weak elastic portion 21 to the outer weak elastic portion 25, a normal knitting portion 29 knitted in the same knitting method with the same material as that of the entire sock 1 and the knitting method is provided.

  The inner weak elastic portion 21 (and the outer weak elastic portion 25) is formed so that one end in the circumferential direction is applied to the inner collar K1 (and the outer collar K2). The length L51 (and the length L55) to the other end connected to is formed to be less than half of the distance from the center of the inner collar K1 (and outer collar K2) to the center of the Achilles tendon. This length L51 (and length L55) can be formed to be about 2 cm to 4 cm when worn by a person, and is preferably formed to be about 2.5 cm to 3.5 cm. In this embodiment, it is formed so as to have a suitable thickness of about 3 cm. The inner weak elastic portion 21 (and the outer weak elastic portion 25) has a shape in which ribs extending in the width direction (vertical direction in FIG. 1) are arranged in the circumferential direction (left and right direction in FIG. 1), and the sock 1 It is made of a knitting method and / or a material that is slightly stronger in the circumferential direction than the normal knitting portion 29 constituting the whole (a little stronger force is required to stretch and a little force to shrink).

  The inner ferroelastic portion 22 (and the outer ferroelastic portion 24) has one end in the circumferential direction connected to the inner weak elastic portion 21 (and the outer weak elastic portion 25), and the other end connected from this one end to the Achilles tendon releasing portion 23. The length L52 (and the length L54) is formed at one quarter or more of the distance from the center of the inner collar K1 (and outer collar K2) to the center of the Achilles tendon, and preferably at one third or more. Yes. The length L52 (and the length L54) can be formed to be about 1.5 cm to 4 cm when worn by a person, and is preferably formed to be about 2 cm to 3.5 cm. In this embodiment, it is formed so as to be a suitable size of about 2.5 cm. The inner strong elastic portion 22 (and the outer strong elastic portion 24) is configured such that the inner weak elastic portion 21 (and the outer weak elastic portion 25) is a rib (inner weak elastic portion 21) extending in the width direction (vertical direction in FIG. 1). And ribs that are more uneven than the outer weak elastic portion 25) are arranged in the circumferential direction (left-right direction in FIG. 1), and are further circumferential than the inner weak elastic portion 21 (and the outer weak elastic portion 25). Is made of a knitting method and / or a material having a strong elasticity (a strong force is required to stretch and a force to shrink).

  The Achilles tendon release portion 23 is provided between the inner ferroelastic portion 22 and the outer ferroelastic portion 24. The Achilles tendon release portion 23 is formed to be less elastic than the inner high-elasticity portion 22 and the outer high-elasticity portion 24 (the force required for extension is weak and the force to shrink is also weak). A length L53 from one end of the Achilles tendon release portion 23 connected to the inner ferroelastic portion 22 to the other end of the Achilles tendon release portion 23 connected to the outer ferroelastic portion 24 is 0.5 cm or more when worn by a person. It can be formed to a length of about 3 cm, and is preferably formed to a length of about 1.0 to 2.5 cm. In this embodiment, the length is preferably about 1.5 cm.

  With this configuration, the inner side weak elastic part 21 and the outer weak elastic part 25 have a higher degree of elasticity than the outer periphery thereof (a strong force is required for extension and a contraction force is strong). The degree of elasticity of the Achilles tendon release portion 23 and the normal knitting portion 29 corresponding to the back of the Achilles tendon can be lowered (the force necessary for calling is weak and the force for contraction is also weak). In this way, the inner weak elastic portion 21 (and the outer weak elastic portion 25) existing between the inner heel K1 (and the outer heel K2) and the site where the Achilles tendon can be brought into contact with the surface of the human foot as much as possible.

  That is, in general socks, the sock material floats from the surface of a person's foot between the heel and the Achilles tendon and often does not come into contact. On the other hand, the inner weak elastic part 21 and the inner strong elastic part 22 (and the outer strong elastic part 24 and the outer weak elastic part 25) existing between the inner collar K1 (and the outer collar K2) and the site where the Achilles tendon is located, By contacting the surface of a person's foot as much as possible, the corresponding part can be stimulated, and it is possible to prevent a person from falling or twisting his / her foot by being grounded while the foot is inclined inward. That is, in general, it is likely that the inside of the foot is lifted and the foot is walked so that the outside of the foot is grounded, and the foot is twisted or falls. On the other hand, the portion between the inner heel K1 (and the outer heel K2) and the site where the Achilles tendon is located can be brought into contact with the body surface as much as possible with the sock 1, unlike a normal sock that is far from the body surface. . In particular, the ligament ligament located below and slightly behind the outer heel K2 can be stimulated by being pressed by the outer strong elastic portion 24 and the outer weak elastic portion 25, thereby naturally raising the little toe side of the foot higher than usual. It can be changed, and it can prevent swells and falls.

  The toe portion 4 is provided with an arch tightening portion 37 that surrounds the upper, lower, left and right rounds with a certain width including the arch portion 8. The arch cinching portion 37 has a width L6 (see FIG. 3, left-right direction in FIG. 3) which can be formed to be about 3 cm to 7 cm when worn by a person, and can be formed to be about 4 cm to 6 cm. In this embodiment, it is preferably formed to be about 5 cm.

  The arch tightening portion 37 has a shape in which ribs extending in the width direction (left-right direction in FIG. 1) are arranged in the circumferential direction (up-down direction and depth direction in FIG. 1), and a normal knitting constituting the entire sock 1 It is made of a knitting method and / or a material that is slightly stronger in the circumferential direction than the portion 29 (see FIG. 2) (a little stronger force is required to stretch and a little stronger force to shrink).

  Due to this elasticity, the arch tightening portion 37 is tightened to lift the sole including the arch toward the instep of the foot with bone. By such tightening, the arch tightening portion 37 of the sock 1 forms a curved arch with the front and rear ends falling from the center 7 to the heel 9 of the foot of the person wearing the sock 1 and the center rising. Can assist. Thereby, it can assist so that it may touch down toward the lower part with respect to the toe part 5 further ahead of the finger ball center 7 which falls below.

  Further, the toe portion 4 is provided with left and right tightening portions 35 that surround the entire circumference of the upper and lower left and right sides with a certain width on the arch side with the fingerball center 7 as an end portion. The width L4 of the left and right tightening portion 35 (see FIG. 3, left and right direction in FIG. 3) can be formed to be about 0.5 cm to 3 cm when worn by a person, and can be about 1 cm to 2 cm. Preferably, it is formed so as to have a suitable thickness of about 1.5 cm in this embodiment.

  The left and right tightening portion 35 includes a left and right strong tightening portion 35a in a range from a position about the center of the thumb to a position about the center of the little finger on the upper surface side (back of the foot), and other ranges (including the soles). ) Left and right weakly tightening portions 35b.

  The right and left weak tightening portion 35b has a shape in which ribs extending in the width direction (left and right direction in FIG. 1) are arranged in the circumferential direction (up and down direction and depth direction in FIG. 1), and a normal knitting that constitutes the entire sock 1 It is made of a knitting method and / or a material that is slightly stronger in the circumferential direction than the portion 29 (see FIG. 2) (a little stronger force is required to stretch and a little stronger force to shrink).

  The right and left strong tightening portion 35a has a shape in which ribs extending in the width direction (left and right direction in FIG. 1) (ribs having a stronger unevenness than the left and right weak tightening portion 35b) are arranged in the circumferential direction (up and down direction and depth direction in FIG. 1). In addition, it is made of a knitting method and / or a material that is more elastic in the circumferential direction than the left and right weakly tightening portion 35b (a stronger force is required to stretch and a stronger force to shrink).

  By this elasticity, the left and right tightening portion 35 tightens the toe side of the first metatarsal bone of the foot and the toe side of the fifth metatarsal bone toward the inside. By such tightening, the right and left tightening portion 35 of the sock 1 assists to create an arch that curves so that the left and right ends of the foot are lowered and the center is raised with respect to the toe portion of the person wearing the sock. Can do. Thereby, the thumb at the tip of the first metatarsal bone and the little finger at the tip of the fifth metatarsal bone can be assisted to spread outward in the lateral direction and downward.

  Further, the left and right tightening portions 35 are knitted so that the cushioning properties thereof do not change much or lower than the surroundings. Thereby, the right-and-left tightening part 35 can prevent the person who wears the sock 1 from walking to make the finger ball (particularly the thumb ball) collide with the ground. That is, when the finger ball (especially the ball ball) has a high cushioning property, the person wearing it walks unconsciously to hit the cushion part against the ground. When that happens, there is a possibility that the finger will advance or a person who is not a finger will become a finger. On the other hand, by not enhancing (suppressing) the cushioning property of the fingerball part, it is possible to promote an appropriate grounding state and how to walk without having to walk like hitting the fingerball against the ground.

  As shown in FIG. 3, at the bottom of the sock 1, a convex stimulation part 31 for four fingers corresponding to the thumb 5a, forefinger 5b, middle finger 5c, and ring finger 5d, and a little finger corresponding to the little finger 5e A convex stimulation part 30 constituted by the convex stimulation part 33 for use is provided. The convex stimulation part 30 is formed of a material having an appropriate cushioning property such as a pile cushion. This makes it easy to contact the soles of the feet and make it easy to give a stimulus, and also makes it difficult to feel uncomfortable even when stepped on during walking.

  The thumb part 5a, the index finger part 5b, the middle finger part 5c, and the ring finger part 5d are all formed longer in length than the width. In particular, the index finger part 5b has a length from the base to the tip. It is formed in the same length as the thumb part 5a. Thus, the length of the index finger varies depending on the person, and even if the index finger is longer than the thumb, an excessively cramped state only on the index finger can be avoided, and each finger can be in a free state.

  In addition, the base portions of the thumb portion 5a, the index finger portion 5b, the middle finger portion 5c, and the ring finger portion 5d are all arranged side by side, but the root of the little finger portion 5e between the little finger portion 5e and the ring finger portion 5d. Only the part is arranged with the arch greatly lowered. Thus, the user can comfortably pass the thumb through the index finger 5b, the middle finger 5c, and the ring finger 5d while the other finger is not cramped while the thumb is firmly passed through the thumb 5a and the little finger is securely passed through the little finger 5e. It is configured to be available.

  The convex stimulation part 31 for four fingers includes a joint line 6a at the base of the thumb 5a (joint line at the base of the human thumb) and a joint line 6b at the base of the index finger 5b (joint at the base of the human index finger). ), The joint line 6c at the base of the middle finger 5c (joint line at the base of the person's middle finger), and the joint line 6d at the base of the ring finger part 5d (the line of the joint at the base of the person's ring finger) Between the joint line position P1 and the fingerball center position P2 (the position of the center of the mother and child spheres), which is the position of the toeball center 7 of the foot. In this embodiment, the four-finger convex stimulating portion 31 is provided closer to the joint line position P1 than the center position of the joint line position P1 and the fingerball center position P2. More specifically, the four-finger convex stimulating portion 31 is provided at the position of the indirect lines 6a, 6b, 6c, 6d, or from the joint line position P1 which is the position of the indirect lines 6a, 6b, 6c, 6d. The distance L2 to the center position of the four-finger convex stimulation section 31 can be provided at a position that is shorter than the distance L3 from the center position of the four-finger convex stimulation section 31 to the fingerball center position P2. Is preferably provided at a position that is less than or equal to one-half of the distance L3, and more preferably at a position that is less than or equal to one-third of the distance L3. It has been.

  Further, the length of the convex stimulation part 31 for four fingers is outside the center of the thumb part 5a (upper side in FIG. 3), that is, from the position that can cover almost the entire thumb part 5a, outside the center of the ring finger part 5d ( The lower side of FIG. 3, that is, the length up to a position where almost the entire ring finger 5 d can be covered.

  The convex stimulation portion 33 for the little finger is located at the position of the center 7 of the toe ball from the joint line position P3 that is the position of the joint line 6e at the base of the little finger 5e (the joint line of the base of the human little finger). It is provided between a certain finger ball center position P2 (position of the center of the mother and child spheres) (or between the center of the little finger balls). This position is on the arch side of the base part of the little finger part 5e, and is clearly different from the four-finger convex stimulation part 31 on the fingertip side of the base part of the little finger part 5e. It is preferable that the convex stimulation portion 33 for little finger is provided at the position of the indirect line 6e or between the joint line position P3 which is the position of the indirect line 6e and the fingerball center position P2.

  A distance L9 from the position in the sole vertical direction (left and right direction in FIG. 3) of the convex stimulation portion for four fingers 31 to the position in the sole vertical direction of the convex stimulation portion for little finger 33 is 0.5 cm to 1.5 cm. In this embodiment, the thickness is preferably about 1 cm.

  The width (the left-right direction in FIG. 3) of the convex stimulation part 31 for the four fingers and the convex stimulation part 33 for the little finger can be set to a width of 0.1 cm to 1.5 cm when worn by a person. It is preferable that the width is 2 cm to 1.0 cm. In this embodiment, the width is preferably about 0.8 cm.

  As shown in the cross-sectional view of FIG. 4, the thicknesses of the convex stimulation portion 31 for four fingers and the convex stimulation portion 33 for little fingers are thicker than the surrounding thickness (the thickness of the normal knitting portion 29). It is comprised so that it may become convex on the (foot side), and it is preferable to set it as 0.1 cm-0.5 cm, and in this Example, it is formed in suitable 0.3 cm.

  With this configuration, the convex stimulation unit 30 stimulates the sole of the foot between the base of the toes where the joint line 6 (6a, 6b, 6c, 6d, 6e) is located and the ball. For this reason, the person who wears the sock 1 naturally bends the toe part 5 due to the body condition reflection, and the toe part 5 comes into contact with the ground. In particular, since the convex stimulation part 30 is dislocated from the fingerball center 7 to the toe part 5 side, it does not exist in the part where the weight is applied between the ground contact surface and the foot, and there is no sense of incongruity for the person wearing it. While providing a good comfort, it is possible to prevent the convex stimulation part 30 from walking as if it hits the ground like a cushion.

  Moreover, since the convex stimulation part 30 is provided in a different position between the convex stimulation part 31 for the four fingers and the convex stimulation part 33 for the little finger, the thumb part 5a and the index finger part are provided by the convex stimulation part 31 for the four fingers. 5b, the middle finger part 5c, and the ring finger part 5d can be bent firmly, and the little finger part 5e can be bent firmly by the convex stimulation part 33 for little fingers. If the convex stimulation part 33 for the little finger is in the same position as the convex stimulation part 31 for the four fingers in the longitudinal direction of the sole, it will contact the back of the little finger part 5e and cannot function sufficiently. On the other hand, since the sock 1 is different only in the position of the convex stimulation part 33 for the little finger corresponding to the little finger part 5e, the little finger part 5e can be given an appropriate stimulus and bent firmly. Can help prevent or improve

  Further, since the convex stimulation part 33 for the little finger is formed long enough to reach the corresponding position of the ring finger part 5d, it is possible to stimulate and bend the little finger part 5e reliably and satisfactorily. Even if the convex finger stimulation part 33 for the little finger is applied to the corresponding part of the ring finger part 5d, there is no problem because the ring finger part 5d is bent by the convex finger stimulation part 31 for the four fingers.

  In addition, since the left and right tightening portions 35 are assisted to create an arch in the left and right direction with respect to the toes, the toes 5 that are firmly opened thereby are bent so as to be grounded by the convex stimulation portion 30. Can be used to prevent and improve the floating finger more effectively.

  Further, by creating an arch in the front-rear direction of the toe by the above-mentioned arch tightening portion 37, the tip of the toe portion 5 is assisted so as to naturally face the grounding direction. It can be used for improvement.

  Note that the normal knitting portion 29 constituting the entire sock 1 is preferably formed using an appropriate elastic material, and a portion formed of a highly elastic knitting method and / or material has a required strong elasticity. Accordingly, it is formed of a material into which a rubber thread having a stronger elastic force is inserted.

In the correspondence between the present invention and the embodiment,
The elastic portions correspond to the inner weak elastic portion 21, the inner strong elastic portion 22, the Achilles tendon release portion 23, the outer strong elastic portion 24, and the outer weak elastic portion 25. However, the present invention is not limited to this embodiment and other various Embodiments can be made.

  For example, in this embodiment, the four-finger convex stimulation part 31 and the little-finger convex stimulation part 33 are separated and provided separately. However, the four fingers shown in FIG. The same convex stimulation part may be provided continuously between the convex stimulation part 31 for fingers and the convex stimulation part 33 for little fingers. In this case as well, the function can be exhibited similarly.

Moreover, although the sock 1 was comprised as a knitted fabric, you may comprise as a textile fabric.
In addition, the sock 1 is a sock having a general length (short socks), but is not limited to this socks, such as a high sock that extends to the shin part, a knee high sock that extends above the knee, and tights. It can be used for socks. Also in this case, the function of the functional unit provided can be exhibited.
