Abstract:
The present application is directed to a valgus big toe rectifying supporter which can prevent pain in and around a valgus big toe and its nail which will be caused by pressure exerted by the valgus toe or its nail, comprising a metatarsal joint securing band which will be firmly wound around the metatarsal joint at the root of the big toe laterally of the foot so that the metatarsal joint may be kept fastened, with this band turned upward, projection pieces extended from the upper end lower edge by the band, and a resilient body positioned between said projection pieces which will be inserted between the big toe and the second toe. The big toe can extend outward, so that its nail is not pressed to cause pain around it. Since the valgus big toe rectifying supporter can fit any big toe regardless of the thickness or length thereof, one can freely move the big toe thereby allowing easy walking.

Description:
FIELD OF THE INVENTION 
     The present invention relates to a supporter for rectifying a valgus big toe. More particularly, the present invention relates to a valgus big toe rectifying supporter for rectifying a valgus big toe which has been bent toward the second toe back to its normal state. 
     PRIOR ART 
     As shown in FIG. 28, a valgus big toe is a deformed big toe 1 bent toward the second toe 2. This is caused when the transverse metatarsal band 3 has slackened, and particularly when the first metatarsal joint 4 has spread to cause the first toe 1 to be bent toward the second toe 2. The major cause which makes the big toe valgus is the fact that, these days, people seldom walk on the rugged ground and wear from their infant days shoes wherein they need not move their big toes, so that the toes are fixed. In particular, the toes are not required to move, thus lose the strength and gradually degenerate, so that it is considered that when one starts to run abruptly, the big toe is pushed outward and bent. It is said that other cause is attributed to the fact that since people wear shoes with narrow toes, they are liable to hurt the tips of their toes, the toes are tightened, and the big toes are bent outward. 
     When the big toe is tightened and bent outward in this way, not only one feels pain on the inside of the first metatarsal joint 4 at the root of the big toe 1, but also the walking strength becomes weak, the balance of the parallel legs becomes unstable, and one is apt to fall and get hurt. 
     To rectify the valgus big toe, the applicant suggested a valgus big toe rectifying supporter in Japanese Patent Application Publication No. 12094/1990 published on Mar. 19, 1990. The constitution of the valgus big toe rectifying supporter disclosed therein will now be described with reference to FIGS. 29 and 30. Reference numeral 11 indicates a cloth joint securing band for wrapping the first metatarsophalangeal joint together with other four metatarsophalangeal joints so that the first metatarsophalangeal joint section at the root of the big toe may be secured to its normal position. A hook and loop fastener is attached to almost all the outer surface of the joint securing band. Reference numeral 12 indicates a cloth big toe enclosing section connected to the joint securing band 11 which is capable of enclosing the big toe. Reference numeral 13 is a cloth pulling band which has an end 13a fixed to the outer side surface of the big toe enclosing section 12 and has a length which can extend from the end 13a along one outer side surface of the foot, then around the heel, and along the other outer side surface of the foot to the joint securing band 11. Hook and loop fasteners are attached to the pulling band 13 and the joint securing band 11 at parts where the puling band 13 will abut on the joint securing band 11. When the valgus big toe rectifying supporter is applied, the big enclosing section is put on the big toe. The whole joints are wrapped in the joint securing band 11. The first metatarsal joint section at the root of the big toe is fastened so that the first metatarsal joint section may be in its normal position and a wrapping end 11a is fixed to the hook and loop fastener on the outer surface. Then, the pulling band 13 is pulled inward so that the valgus big toe may be returned back to its normal position, a section 13b is fixed by the joint securing band 11, the pulling band 13 is put around the heel 14, and the other end 13c is fixed to the joint securing band 11 at the most suitable position by the hook and loop fastener. However, although this valgus big toe rectifying supporter is effective for rectifying a valgus big toe, the valgus big toe rectifying supporter has a defect that even thought the valgus big toe is pulled inward to the inner normal position, the big toe and its nail cannot be prevented from being pressed and one feels pain caused around the big toe or its nail. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a valgus big toe rectifying supporter which is effective for rectifying a valgus big toe and can prevent one from having pain in the valgus big toe or around its nail which will be caused by pressure on the valgus big toe or its nail. 
     The valgus big toe rectifying supporter according to the present invention comprises a metatarsophalangeal joint securing band which will be firmly wound around the metatarsal joint at the root of the big toe laterally of the foot so that the metatarsal joint may be kept fastened, a hook and loop fastener provided at one end of said metatarsophalangeal joint securing band, first and second projection pieces extending from the forward edge of said metatarsophalangeal joint securing band, and a resilient member that is fixed between said first projection piece and said second projection piece and will be inserted between the big toe and the second toe. Owing to this constitution, the pressing force of a valgus big toe against the second toe is absorbed and weakened by the resilient member, the pain in the big toe and around its nail can be alleviated, and the deformed big toe can be rectified to its normal position. Using this valgus big toe rectifying supporter, the big toe can extend outward, so that its nail is not pressed to cause pain around it. The valgus bid toe rectifying supporter can fit various big toes, such as a thick big toe and a long big toe, and allows the big toe to move freely, and therefore, for example, there is an effect that one can exert a force in the big toe to make the walking easy.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     A first embodiment of the present application will now be described with reference to FIGS. 1 and 2. A first-metatarsophalangeal joint securing band 5 is a felt band having a length to wrap laterally a section including the first metatarsophalangeal joint 4 of the big toe 1. A first projection piece 6 is extended from the front edge of a lower surface 5a between the big toe 1 and the second toe 2 and the band 5 is turned to form an insertion opening 7 so that the second toe, the third toe, the fourth toe, and the little toe can be inserted thereinto. Further, the band 5 has a second projection piece 8 extended from the front edge of an upper surface 5b and is opposed to the first projection piece 6 of the lower surface 5a and a resilient member 9 is fixed between the first and second projection pieces 6 and 8. The band upper surface 5b has its end extended slightly beyond the second projection piece 8 toward the big toe. The band lower surface 5a has a hook and loop fastener 10 fixed at its end section on the big toe side. 
     When it is put to use, the second toe to the little toe are inserted into the insertion opening 7 shown in FIG. 1, the resilient member 9 is inserted between the big toe 1 and the second toe 2, one end of the band 5 is turned upward as shown in FIGS. 2 and 3, the section of the band 5 corresponding to the first metatarsophalangeal joint is pulled toward the little toe, and the hook and loop fastener 10 is attached fixedly to the end section of the upper surface 5b of the band 5 with the first metatarsophalangeal joint 4 fastened.
