Abstract

An arch-adaptive smart insole according to the present invention includes: an insole cushion foam (10) which has a shape corresponding to the shape of the foot and which is made of an elastic foam; and an arch spring module (20) which is loaded in a first loading well (11) of the insole cushion foam (10), and which supports the arch of the foot by means of the interposition of a closing part (18) of the insole cushion foam (10) for closing the upside of the first loading well (11), wherein the arch spring module (20) comprises at least a first coil spring (21) and a second coil spring (22), and the first coil spring (21) having a diameter smaller than that of the second coil spring (22) is positioned inside the second coil spring (22).

1 . An arch adaptive smart insole, comprising:
 an insole cushion foam ( 10 ) made of foam having a shape corresponding to the shape of a foot and having elasticity; and   an arch spring module ( 20 ) seated in a first seat well ( 11 ) of the insole cushion foam ( 10 ), and supporting an arch of a foot with a closing part ( 18 ) of the insole cushion foam ( 10 ), which closes the top of the first seat well ( 11 ), therebetween,   wherein the arch spring module ( 20 ) includes at least a first coil spring ( 21 ) and a second coil spring ( 22 ), and the first coil spring ( 21 ) having a smaller diameter than the second coil spring ( 22 ) is positioned inside the second coil spring ( 22 ).   
     
     
         2 . The arch adaptive smart insole of  claim 1 , wherein the upper end of the second coil spring ( 22 ) is configured lower than the upper end of the first coil spring ( 21 ) to correspond to the arch of a foot. 
     
     
         3 . The arch adaptive smart insole of  claim 2 , wherein the first coil spring ( 21 ) and second coil spring ( 22 ) are formed by spirally winding a flat plate material having elasticity and having a band shape of which the width is larger than the thickness, and
 flat surfaces of the flat plate materials each support the closing part ( 18 ) of the insole cushion foam ( 10 ) at the upper ends of the first coil spring ( 21 ) and second coil spring ( 22 ).   
     
     
         4 . The arch adaptive smart insole of  claim 3 , wherein the arch spring module ( 20 ) further includes:
 a disc-shaped moving supporting part ( 24 ) supporting the first coil spring ( 21 ) and the second coil spring ( 22 ) with lower ends of the first coil spring ( 21 ) and the second coil spring ( 22 ) seated on a first surface thereof; and   a third coil spring ( 23 ) supporting a load through the disc-shaped moving supporting part ( 24 ) with an upper end thereof seated on a second surface opposite to the first surface of the disc-shaped moving supporting part ( 24 ), and   the disc-shaped moving supporting part ( 24 ) can be moved up and down in the first seat well ( 11 ).   
     
     
         5 . The arch adaptive smart insole of  claim 4 , further comprising a rear spring module ( 30 ) seated in a second well ( 11 ) of the insole cushion foam ( 10 ) and supporting the heel of a foot,
 wherein the rear spring module ( 30 ) includes:   a fourth coil spring ( 31 ) and a fifth coil spring ( 32 ) coaxially disposed and different in diameter; and   a solid supporting part ( 33 ) supporting an upper end of the fourth coil spring ( 31 ) and an upper end of the fifth coil spring ( 32 ), positioned under a closing part ( 19 ) of the second seat well ( 11 ), and made of a hard material.   
     
     
         6 . The arch adaptive smart insole of  claim 5 , further comprising a cover ( 40 ) supporting lower ends of the arch spring module ( 20 ) and the rear spring module ( 30 ), closing lower portions of the first seat hole and the second seat hole ( 12 ), and bonded to the insole cushion foam ( 10 ). 
     
     
         7 . The arch adaptive smart insole of  claim 5 , having at least one through-hole ( 13 ) passing through the top and the bottom of the insole cushion foam ( 10 ), and
 the through-hole ( 13 ) communicates with the first seat hole and the second seat hole ( 12 ) using a trench configured in the insole cushion foam ( 10 ).   
     
     
         8 . The arch adaptive smart insole of  claim 1 , wherein the height of the inside part of a foot is smaller than the height of the outside part of a foot at a heel part of the insole cushion foam ( 10 ). 
     
     
         9 . A natural treatment shoe comprising the arch adaptive smart insole of  claim 1 .
