Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to improvements in various socks such as tights, stockings, over knees, high socks, short socks, anklets, foot covers, and toe-mounted devices, and more particularly to socks for correcting hallux valgus.
[0002]
[Prior art]
The hallux valgus is a kind of deformation of the foot, and means a state where the first foot of the foot is bent toward the second foot as shown in FIG.
[0003]
This occurs when the lateral metatarsal ligament loosens and the metatarsal joint opens, leading to varus of the first metatarsal bone, resulting in the valgus of the first heel.
[0004]
The cause of this hallux valgus is that the development of plantar muscles is hindered because shoes with excellent shock absorption are worn from an early age, and when the shoes with pointed toes such as high heels are worn, There is a theory that it is tightened and receives the action of bending the first rod outward.
[0005]
Such a hallux valgus is not only painful in the first heel, but also loses balance and causes low back pain.
[0006]
Various inventions and devices have been made to correct the hallux valgus that causes such harm. For example, Japanese Utility Model Laid-Open No. 6-13814 proposes a supporter that has an action of winding around the first heel and the former and causing the first heel to be varnished. Japanese Patent Application Laid-Open No. 2001-269367 proposes a sock in which the toes are formed in two forks and the first heel is varnished by attaching a hallux valgus prevention body.

[Problems to be solved by the invention]
The device described in Japanese Utility Model Laid-Open No. 6-13814 is troublesome to wear. In addition, when wearing shoes, it is necessary to further wear socks. As a result, it is bulky, so that the toes are tightened and the pain is increased.
[0010]
In addition, the invention described in Japanese Patent Laid-Open No. 2001-269367 requires a step of attaching a hallux valgus prevention body in addition to knitting by a sock knitting machine, which causes an increase in price and does not have practicality as a product.
[0011]
Accordingly, an object of the present invention is to provide a sock capable of correcting the hallux valgus only by wearing the sock or a sock for a hallux valgus that can be manufactured only by knitting using a sock knitting machine.
[0012]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the sock according to claim 1 is formed in a range from the toe to the heel part with a hard stretchable part that acts in the direction of opening the toe at both side edges of the sock in which the toe is bifurcated. .
[0013]
The sock according to claim 2 is provided with a shape in which the hard stretchable part circulates not only from both side edges but also from the upper part to the back part of the upper part.
[0014]
The sock according to claim 3 is knitted with a combination of tack knitting and floating knitting on the difficult stretchable part.
[0015]
The sock according to claim 4 is knitted with tuck knitting and floating knitting as well as splicing knitting at the difficult stretch part.
[0016]
The sock according to claim 5 is knitted with a knitting yarn with a difficult stretchable part.
[0017]
The following will describe how the present invention configured as described above works to solve the problems with reference to the drawings.
[0018]
FIG. 1 is a front view of a sock according to claim 1, FIG. 2 is a front view of the sock according to claim 2, FIG. 3 is a rear view thereof, and FIG. FIG. 5 is a diagram showing the state of use of the present invention.
[0019]
As shown in FIG. 1, the sock of Claim 1 has the hard-to-contract part 1a in the edge part on both sides. Since this hard stretchable part 1a is poor in stretchability compared with other parts, when it is attached, a force is applied in the direction indicated by the arrow in FIG. As a result, when actually mounted, the toes open as shown in FIG.
[0020]
In other words, it is possible to apply a force in the direction of varying the hallux valgus and correct the hallux valgus.
[0021]
Further, in the sock according to claim 2, the hard stretchable part 1b is provided in a shape that circulates from the upper part to the back side of the upper part as well as the side edge parts. When the hard stretchable portion 1b is worn, it applies force in the direction indicated by the arrow in FIG. 2, that is, the direction in which the middle foot joint is tightened.
[0022]
As mentioned above, hallux valgus is caused by the opening of the metatarsal joint. Therefore, the hallux valgus can be corrected by tightening the metatarsal joint with the hard stretchable portion 1b.
[0023]
In the sock according to claim 3, the hard stretchable part is knitted by combining tuck knitting and floating knitting. Here, the tuck knitting has a property of not easily extending in the wale direction (longitudinal direction), and the floating knitting has a property of not easily extending in the course direction (lateral direction).
[0024]
Due to such properties, it is possible to form a difficult stretchable portion having poor stretchability only by knitting with a knitting machine.
[0025]
In the sock according to the fourth aspect, the difficult expansion / contraction portion is knitted with tuck knitting and floating knitting as well as splicing knitting. Here, the splicing knitting is a knitting method in which other knitting yarn is added to the ground knitting yarn and fed, and the portion can be reinforced. In this way, it is possible to add more stretchability by reinforcing with splicing yarn.
[0026]
In the sock according to claim 5, the difficult expansion / contraction part is knitted by a spliced yarn knitting in which other knitting yarn is added to a ground knitting yarn such as flat knitting. As described above, by partially supplying yarn, the portion is reinforced, so that it is possible to impart difficulty stretchability.
[0027]
