Description

  The present invention relates to a sock, and more particularly to a sock that can prevent slipping between the shoe and the foot even when one foot is rotated as an axis foot.

  Socks are usually used for the purpose of protecting feet and keeping warm, but improving wearability is being studied. For example, Patent Document 1 describes a sock in which a large number of slip stoppers are arranged on the sole of the foot of the sock in order to suppress slipping between the shoe and the foot during walking or sports. Further, in Patent Document 2, in order to prevent the sock from slipping off from the foot when the infant crawls, the instep, for example, the inner surface in the vicinity of the scaphoid or the vicinity of the scaphoid, Infants socks have been proposed in which non-slip materials are provided in sheet form on both the inner and outer surfaces.

Utility Model Registration No. 309334 Special table 2010-126864

  However, the conventional socks have a problem that slipping between the shoe and the foot cannot be suppressed when the foot socks are rotated while one foot is used as a shaft foot during sports such as golf and baseball.

  In order to solve the above-described conventional problems, the present invention provides a sock that can suppress slipping between a shoe and a foot even when one foot is rotated as an axis foot.

  The present invention has an anti-slip portion on the instep side of the sock, and the anti-slip portion includes all of the proximal phalanges from the first proximal phalanx to the fifth proximal phalanx, the first metatarsal, the second The present invention relates to a sock characterized by being arranged in a region covering up to the middle between the metatarsal bone and the fifth metatarsal bone.

  When the socks of the present invention are worn, slipping between the shoes and the feet can be effectively suppressed even when walking, or when playing sports such as golf and baseball, even when one foot is rotated as an axis foot.

FIG. 1 is a schematic top view of a sock in an embodiment of the present invention. FIG. 2A is a schematic partial plan view of an instep side of a sock in one embodiment of the present invention, and FIG. 2B is a sectional view of a protrusion. FIG. 3A is a schematic top view of a sock according to another embodiment of the present invention, and FIG. 3B is a bottom view thereof. FIG. 4 is a schematic outer side view illustrating a state where a marker is attached to the upper of the shoe. FIG. 5 is a top view of the upper of the shoe showing the degree of extension of the upper when a driver shot is performed in golf. FIG. 6 is a schematic top view of the foot skeleton.

  The present inventors, even when wearing socks with anti-slip on the sole of the foot, when walking or playing sports such as golf and baseball, We investigated the cause of slipping failure. As a result, when walking or playing sports such as golf and baseball, there is a face where the foot floats in the shoe, even if you wear socks with a non-slip on the back of the foot, slipping between the shoe and the foot I came up with something I can't control. In addition, when walking and playing sports such as golf and baseball, it has been found that the fit feeling is improved by suppressing the slip of the foot and the part where the upper distortion of the shoe is large.

  The distortion of the upper of the shoe when rotating with one foot as the pivot was examined using a shoe made of neoprene in the upper. Specifically, a driver shot was performed with the upper wearing shoes made of neoprene. At that time, the coordinates of the marker pasted on the upper of the shoe were measured by Eagle (manufactured by Motion Analysis), and the degree of distortion of the upper was calculated from the result. The marker 30 was affixed to the shoe upper 100 as shown in FIG. FIG. 5 shows a top view of the shoe upper 100 showing the degree of distortion of the upper. In FIG. 5, the degree 200 indicates the degree of distortion of the upper, and means that the distortion increases as it goes from I to II. FIG. 6 shows a schematic top view of the foot skeleton. 5 and 6, the upper 100 has a large distortion in the region covering all of the first to fifth proximal phalanges and the middle of the first metatarsal bone, the second metatarsal bone, and the fifth metatarsal bone. I understand that. That is, it was found that the upper 100 was distorted when the back side of the foot during exercise such as when rotating with one foot as an axis foot floated in the shoe.

  In the present invention, all the proximal phalanges from the first proximal phalanx to the fifth proximal phalanx on the instep side of the sock, and to the middle of the first metatarsal bone, the second metatarsal bone, and the fifth metatarsal bone By placing an anti-slip part (hereinafter also referred to as “instep side anti-slip part”) in the area covering the foot, when walking or playing sports such as golf and baseball, Even if it rotates, slipping between the shoes and the feet can be suppressed, and the fit between the shoes and the feet is improved. Even when the upper of the shoe is made of a soft material such as neoprene, it can be suitably used. Even if the upper is hard to stretch and the shoe fixes the foot, there is a gap between the foot and the upper in the shoe, and vertical foot movement occurs.

  The sock may have a non-slip portion on the sole, in addition to the instep side non-slip portion. For example, it is possible to further improve the fit with the shoes by disposing a non-slip portion in a region covering the thumb ball, the first finger, the buttocks, and the like on the sole side.

  The anti-slip portion is preferably a protrusion group including a plurality of protrusions made of resin. Detachment can be facilitated. The shape of the protrusion is not particularly limited, and examples thereof include a linear shape, a honeycomb shape, a todd shape, a cylindrical shape, a semispherical shape, a quadrangular prism shape, a triangular prism shape, a conical shape, a quadrangular pyramid shape, a triangular pyramid shape, and combinations thereof. Any shape may be sufficient. The size of the protrusions and the interval between the protrusions are not particularly limited, and may be appropriately adjusted according to a desired degree of slip prevention.

  The resin is not particularly limited, and for example, a resin having elasticity can be used. Examples of the resin having elasticity include polyurethane, silicone resin, polyvinyl chloride, polyamide elastomer, polyester elastomer, rubber elastomer, olefin elastomer, polyethylene, polypropylene, nylon, EVA resin (ethylene-vinyl acetate copolymer), Examples include ABS resin (acrylonitrile-butadiene-styrene copolymer) and acrylic resin.

  For example, these resin materials are applied to a predetermined region on the instep side of the socks by a printing process in a flowable state (for example, in a liquid state), heated, and cured to form an anti-slip portion. By adjusting the shape, size, density, and the like of each protrusion, the degree of anti-slip can be adjusted. The anti-slip portion on the sole side can be formed in the same manner.

  In the present invention, the sock body preferably has elasticity from the viewpoint of wearing feeling. The elongation in the vertical direction and / or the horizontal direction under a 15N load measured according to JIS L 1096 is preferably 40% or more, and more preferably 60% or more.

  In the present invention, the fiber used for the sock body is preferably a fiber yarn including an elastic yarn. The elastic yarn is preferably at least one selected from the group consisting of a polyurethane elastic yarn and a polyester elastic yarn. This is because it is highly stretchable and suitable for socks. The elastic yarn may be used as a bare yarn, in alignment with a non-elastic yarn (rigid yarn), or the surface is coated with polyester fiber, nylon fiber, acrylic fiber, wool, cotton, etc. It may be used as a covered yarn.

  This will be described below with reference to the drawings. FIG. 1 is a schematic top view of a sock according to an embodiment of the present invention, FIG. 2A is a schematic partial plan view of the instep, and FIG. 2B is a sectional view of a protrusion. The sock 1 has a non-slip portion 2 on the instep side, and the non-slip portion 2 includes all of the basic phalanges from the first basic phalanx to the fifth basic phalanx, the first metatarsal bone, and the second middle phalanx. It arrange | positions in the area | region which covers to the middle vicinity of a foot bone and a 5th metatarsal bone. Further, the non-slip is not provided on the instep side corresponding to the intermediate wedge upper bone and the scaphoid bone so as not to inhibit the flexibility of the ankle, thereby further improving the fit.

  The anti-slip part 2 is a protrusion group including a plurality of protrusions 2a made of resin. As shown in FIG. 2B, when the projection 2a is semispherical, it is not particularly limited, but it is easy to put on and take off the sock and effectively slide the shoe and the foot when one foot is rotated as an axis foot. From the viewpoint of suppression, the height H1 is set to 0.1 to 5 mm, the length L1 is set to 0 to 30 mm, the distance L2 between the protrusions is set to 0.1 mm or more, the lateral pitch P1 of the protrusion group is set to 1 to 30 mm, and the protrusion group The vertical pitch P2 is preferably 1 to 30 mm. Here, the length L1 being 0 mm means that the length L1 cannot be measured with a measuring tool capable of measuring up to 0.1 mm units.

  In the above description, the case where the protrusion 2a has a substantially semispherical shape has been described. However, the shape of the protrusion 2a is linear, honeycomb, todd, semicircular, cylindrical, quadrangular, triangular, conical, and quadrangular. Any shape such as a shape, a triangular pyramid shape, or a combination thereof may be used. The size of the protrusions and the interval between the protrusions are not particularly limited, and may be appropriately adjusted according to the desired degree of slip prevention.

  FIG. 3A is a schematic top view of a sock according to another embodiment of the present invention, and FIG. 3B is a bottom view thereof. As shown in FIG. 3A, the sock 10 of this embodiment has a non-slip portion 2 on the instep side, like the sock 1, and the non-slip portion 2 extends from the first basic phalanx to the fifth base. It is arranged in a region that covers all of the proximal phalanx up to the phalanx and the middle of the first metatarsal bone, the second metatarsal bone, and the fifth metatarsal bone. In FIG. 3A, the same parts as those in FIG. 1 are denoted by the same reference numerals, and redundant description is omitted.

  Moreover, as shown in FIG. 3B, the sock 10 has a non-slip portion 3 on the sole side. It is preferable that the anti-slip | skid part 3 is arrange | positioned in the area | region which covers a thumb ball, a 1st finger, a buttocks, etc. The anti-slip part 3 includes a plurality of protrusions 3a made of resin. The protrusion 3a may have the same shape and size as the protrusion 2a, or may have a different shape and size from the protrusion 2a. In the anti-slip part 3, the distance between the protrusions, the horizontal pitch of the protrusion group, and the vertical pitch of the protrusion group may be the same as in the case of the anti-slip part 2, or different from the case of the anti-slip part 2. .
