Flat foot orthosis

Abstract

A flat foot orthosis has two bodies, and each one of the two bodies has a wearing space, a foot portion, an ankle portion, a shank portion, a substrate, and a first elastomer. The substrate and the first elastomer are disposed adjacent to each other, and surround the wearing space. The substrate extends from the foot portion to the shank portion through the ankle portion. The first elastomer extends from an instep of the foot portion at a cuboid bone of a wearer through a lateral side of the foot portion, a sole of the foot portion, and an arch of the foot portion in order, wraps over a navicular bone of the wearer, and extends outwardly combining upwardly through the ankle portion at a talus bone of the wearer toward the shank portion.

What is claimed is: 
     
         1 . A flat foot orthosis comprising:
 two bodies, each one of the two bodies having
 a wearing space disposed inside the body; 
 a foot portion having
 a sole located on a bottom of the foot portion; 
 an instep located on a top of the foot portion; 
 an arch located on one of two horizontal sides of the foot portion, facing the other one of the two bodies, and connected to the sole and the instep; and 
 a lateral side located on the other one of the two horizontal sides of the foot portion, and connected to the sole and the instep; 
 
 an ankle portion connected to the foot portion; 
 a shank portion connected to the ankle portion; 
 a substrate surrounding the wearing space, and extending from the foot portion to the shank portion through the ankle portion; and 
 a first elastomer disposed adjacent to the substrate, surrounding the wearing space, extending from the instep of the foot portion at a cuboid bone of a wearer through the lateral side, the sole, and the arch in order, wrapping over a navicular bone of the wearer, and extending through the ankle portion at a talus bone of the wearer toward the shank portion. 
   
     
     
         2 . The flat foot orthosis as claimed in  claim 1 , wherein the first elastomer of each one of the two bodies surrounds and fetters the shank portion of the body. 
     
     
         3 . The flat foot orthosis as claimed in  claim 2 , wherein
 each one of the two bodies has
 a toe portion connected to a front end of the foot portion, and having a hallux sheath; 
 a hallux valgus region located between the hallux sheath and the arch of the foot portion; and 
 a second elastomer extending from the hallux sheath at a top of the wearer's hallux, through a bottom of the wearer's hallux, further extending upwardly through and wrapping the hallux valgus region, through the instep toward the ankle portion, and connected to the first elastomer; 
   wherein the substrate extends from the foot portion to the toe portion.   
     
     
         4 . The flat foot orthosis as claimed in  claim 1 , wherein
 each one of the two bodies has
 a knee portion connected to the shank portion; and 
 a thigh portion connected to the knee portion; 
   wherein the first elastomer of each one of the two bodies extends to the thigh portion through a rear side of the shank portion, obliquely extends in combination with upward and inward turns through an inner side of the knee portion, extends through a front side of the thigh portion, and surrounds and fetters the thigh portion.   
     
     
         5 . The flat foot orthosis as claimed in  claim 4 , wherein each one of the two bodies has
 a toe portion connected to a front end of the foot portion, and having a hallux sheath;   a hallux valgus region located between the hallux sheath and the arch of the foot portion; and   a second elastomer extending from the hallux sheath at a top of the wearer's hallux, through a bottom of the wearer's hallux, further extending upwardly through and wrapping the hallux valgus region, through the instep toward the ankle portion, and connected to the first elastomer;   wherein the substrate extends from the foot portion to the toe portion.   
     
     
         6 . The flat foot orthosis as claimed in  claim 1 , wherein the flat foot orthosis has
 each one of the two bodies having
 a knee portion connected to the shank portion; and 
 a thigh portion connected to the knee portion; and 
   a pelvis portion connected to the two thigh portions of the two bodies, and wrapping over a hip joint of the wearer;   wherein the first elastomer of each one of the two bodies extends through a rear side of the shank portion, obliquely extends in combination with upward and inward turns through an inner side of the knee portion, spirally extends through the thigh portion and the pelvis portion, wraps the wearer's hip joint, intersects with the first elastomer of the other one of the two bodies at a rear side of the wearer's hip behind the wearer's pelvis, extends and wraps over a sacroiliac joint and an iliac crest of the wearer, and surrounds and fetters where the wearer's pelvis and the wearer's waist meet.   
     
     
         7 . The flat foot orthosis as claimed in  claim 6 , wherein each one of the two bodies has
 a toe portion connected to a front end of the foot portion, and having a hallux sheath;   a hallux valgus region located between the hallux sheath and the arch of the foot portion; and   a second elastomer extending from the hallux sheath at a top of the wearer's hallux, through a bottom of the wearer's hallux, further extending upwardly through and wrapping the hallux valgus region, through the instep toward the ankle portion, and connected to the first elastomer;   wherein the substrate extends from the foot portion to the toe portion.
