Benefits of technology

[0006]Therefore, a main object of the present invention is to provide corrective socks for correcting hallux valgus and digitus quintus varus, which is constituted so that the hallux valgus and the digitus quintus varus can be sufficiently corrected.

Problems solved by technology

Nevertheless, the elastic forces for pressing the distal caput (71D) and the proximal caput (75P) by the elastic annular bands are relatively small, and thus it is difficult to sufficiently correct the hallux valgus and the digitus quintus varus.
Nevertheless, similar to US 200310005601 A1, elastic forces for pressing a distal caput (71D) and a proximal caput (75P) by the elastic annular bands are relatively small, and thus it is difficult to sufficiently correct hallux valgus and the digitus quintus varus.

first embodiment

[0038]With reference to FIG. 4 which is a perspective view of a first embodiment of a corrective sock according to the present invention, the corrective sock, into which a light leg of a person is put, is generally indicated by reference numeral 1.

[0039]The corrective sock 1 includes a leg portion 12 and a foot portion 13, and may be produced from suitable yarns, rubber yarns and so on by a circular knitting machine.

[0040]The foot portion 13 has an elastic annular band 13A which is formed so as to cover both a metatarsophalangeal joint portion (61M in FIG. 1) and a Lisfranc joint portion (61L in FIG. 1) between which first, second, third, fourth and fifth metatarsals (71, 72, 73, 74 and 75 in FIG. 1) extend. For example, the elastic annular band 13A includes rubber yarns as the weft, so that the respective distal and proximal caputs (71D, 75) of the first and fifth metatarsals (71, 75) elastically pressed outwardly and inwardly with respect to a vertical central axis passing through...

second embodiment

[0050]FIGS. 6 and 7, corresponding to FIGS. 4 and 5, shows a second embodiment of the corrective sock according to the present invention. Note, in FIGS. 6 and 7, the features to those of FIGS. 4 and 5 are indicated by the same references.

[0051]The second embodiment is substantially identical to the first embodiment of FIGS. 4 and 5 except that an single reinforcing band 13D is substituted for the pair of reinforcing bands 13B and 13C.

[0052]The reinforcing band 13D also may be formed on the elastic band 13A by knitting non-stretchable strong yarns into the elastic band 13A, using either a wrapping stitch method or a plating stitch method. Also, preferably, the non-stretchable strong yarns are entangled with the rubber yarns of the elastic band 13A.

[0053]As shown in FIG. 7, the reinforcing band 13D slantly surrounds around the foot so as to cover the distal caput (71D) of the first metatarsal (71) and the distal caput 75D of the fifth metatarsal (75). Thus, similar to the aforesaid fi...

Abstract

In a corrective sock for correcting hallux valgus and digitus quintus varus of a foot, the sock has a foot portion, and an elastic band formed in the foot portion so as to cover both a metatarsophalangeal joint portion and a Lisfranc joint portion of the foot between which first, second, third, fourth and fifth metatarsals extend. A first reinforcing band is formed on the elastic band to cover a distal caput of the first metatarsal and a distal caput of the fifth metatarsal, and a second reinforcing band is formed on the elastic band to cover a proximal caput of the first metatarsal and a pioximal caput of the fifth metatarsal.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to corrective socks for correcting hallux valgus and digitus quintus varus to thereby return a transverse arch and a longitudinal arch to a normal state, so that a normal foot balance can be recovered on the soles of foots.[0003]2. Description of the Related Art[0004]Human beings have been always engaged with the gravity so as to balance themselves on the foots since they acquired bipedalism. A human body is sophisticatedly and delicately created so as to be balanced as a whole with the gravity. Thus, when there are instabilities, such as hallux valgus, digitus quintus varus and so on, in the foots, especially the soles of the foots, the instabilities cause unbalances back and forth, right and left, up and down and so on in the human body. Further, whenever taking a walk, the instabilities on the soles of the foots causes harmful stresses, such as excess impacts, torsional waves and so on, ...
