Balance board

Abstract

A balance board ( 100 ) having a first balance side ( 110 ) and a second balance side ( 210 ) to support the user. A plurality of convex rockers ( 160 and 260 ) is unreleasably attached to the balance board surface to provide rocking during exercise. The one-foot balance board has two left ( 130, 230 ) and right ( 132, 232 ) indicators on the same platform, which can use for both right and left feet respectively. The rocker direction can be changed from horizontal to vertical by turning the rocker balance board upside down.

         2 . The balance board ( 100 ) as claimed in  claim 1 , wherein the left indicator ( 130 ) and the right indicator ( 132 ) on the first ( 120 ) and second balance side surface ( 220 ) in a cross position with an angle of 90°. 
     
     
         3 . The balance board ( 100 ) as claimed in  claim 1 , wherein at least one convex rocker includes two convex rockers ( 160  and  260 ) unreleasably engaged to the first ( 120 ) and second balance surface ( 220 ). 
     
     
         4 . The balance board ( 100 ) as claimed in  claim 1 , wherein at least one convex rocker engaged to the first ( 120 ) and second balance side surface ( 220 ) is positioned oppositely in parallel. 
     
     
         5 . The balance board ( 100 ) as claimed in  claim 1 , wherein the second balance side surface ( 220 ) is affixed with the convex rocker ( 260 ) in the form of a truncated prolate spheroid shape, located in a perpendicular orientation to the convex rocker ( 160 ) of the first balance side surface ( 120 ). 
     
     
         6 . The balance board ( 100 ) as claimed in  claim 1 , wherein the convex rockers ( 160  and  260 ) consist of the convex surfaces covered by anti-slip feet materials. 
     
     
         7 . The balance board ( 100 ) as claimed in  claim 1 , wherein one or more cutouts ( 310  and  320 ) are provided through the entire thickness of the balance board ( 100 ), the cutouts are configured to create an empty space for the user's toes, except for a big toe to have a firm hold on the rear of the cutouts during exercises, while the big toe is put on the first ( 120 ) and second balance side surface ( 220 ). 
     
     
         8 . The balance board ( 100 ) as claimed in  claim 1 , wherein the convex surface on the convex rockers ( 160  and  260 ) defines the rate of change of the angle of deflection of the balance board, the balance board may be deflected as much as perpendicular to the ground between 10° and 35°. 
     
     
         9 . The balance board ( 100 ) as claimed in  claim 1 , wherein each fixture is a bolt and screw. 
     
     
         10 . A balance board ( 100 ), comprising:
 a first balance side ( 110 ) and a second balance side;   the first balance side ( 110 ) comprising a first balance side surface ( 120 );   wherein the first balance side surface ( 120 ) having a left indicator ( 130 ) and a right indicator ( 132 ), at least one convex rocker ( 160 ) engaged to the first balance side surface ( 120 );   the second balance side comprising a second balance side surface ( 220 );   wherein the second balance side surface ( 220 ) having a left indicator ( 230 ) and a right indicator ( 232 ), at least one convex rocker ( 260 ) engaged to the second balance side surface;   one ( 310 ) or more ( 320 ) cutouts through the first ( 120 ) and second balance side surface ( 220 ); and wherein the balance board ( 100 ) can be turned upside down from the first balance side ( 110 ) to the second balance side ( 210 ) to change the motion directions of the foot and ankle based on the change in the directions oriented by the first ( 160 ) and second balance sides' convex rockers ( 260 ).   
     
     
         11 . The method of performing exercise of the balance board ( 100 ) comprising the first ( 110 ) and second ( 210 ) balance side, each side comprising the first ( 120 ) and second ( 220 ) balance side surface having the left ( 130 ) and right indicator ( 132 ) with at least one convex rocker engaged to the side surface and one or more cutouts ( 310  and  320 ) through the balance side surface, the method comprising:
 standing on the balance board ( 100 ) with placing the user's foot on the left ( 130 ) or right ( 132 ) indicator respectively on the first ( 110 ) or second balance ( 210 ) side and placing the user's toes except for a big toe through the cutout; 
 performing balancing exercises on front-back motion of the foot in the first direction oriented by the second balance side's convex rockers ( 260 ); and 
 turning upside down the balance board ( 100 ) and performing balancing exercises on left-right motion of the foot in the second direction oriented by the first balance side's convex rockers ( 160 ). 
 
     
     
         12 . The method as claimed in  claim 11 , wherein the balance board ( 100 ) after being turning upside down, the second balance side ( 210 ) faces up such that the second side's convex rockers ( 260 ) simultaneously upwardly protrude, the facing down first balance side ( 110 ) causes first side's convex rockers ( 160 ) simultaneously downwardly protrude with the convex surfaces of the first side's convex rockers ( 160 ) contacts the supporting structure in the second direction, the user may do rocking motions in the second direction which is substantially deviated from the first direction. 
     
     
         13 . The method as claimed in  claim 11 , wherein the first and second direction are 90° deviations.
