Balance training device

Abstract

A balance training device includes a base having a connection bar which includes a transverse bar and a tilt bar. A transmission unit connected to the tilt bar and includes a pedal frame, a crank, a link, a shaft, a driving wheel, a belt and a fly wheel. The link unit is connected to the transverse bar and includes a driving plate, a first link, a second link, a third link, a fourth link and a seat frame. The seat frame includes a seat with two handles on two ends thereof and the link unit moves the user back and forth, and up and down so that the user's upper body is exercised. The pedal frame includes two pedals so that the user's feet are rested on the pedals and the user's body is moved like riding a horse.

1 . A balance training device comprising:
 a base ( 1 ) having a first leg on which a frame ( 11 ) is connected and a connection bar ( 12 ) connected between the frame ( 11 ) and a second leg, the connection bar ( 12 ) including a transverse bar ( 13 ) connected to the frame ( 11 ) and a tilt bar ( 14 ) connected to the second leg;   a transmission unit ( 2 ) having a pedal frame ( 21 ), a crank ( 22 ), a link ( 23 ), a shaft ( 24 ), a driving wheel ( 25 ), a belt ( 26 ) and a fly wheel ( 27 ), the pedal frame ( 21 ) having a securing portion ( 211 ) on a first end thereof and two pedals ( 213 ) connected on two ends of a Y-shaped second end of the pedal frame ( 21 ), the crank ( 22 ) having a first end pivotably connected to the pedal frame ( 21 ) and a second end of the crank ( 22 ) pivotably connected with a first end of the link ( 23 ), a second end of the link ( 23 ) fixed to a first end of the shaft ( 24 ), a second end of the shaft ( 24 ) extending through the driving wheel ( 25 ) and the tilt bar ( 14 ), the belt ( 26 ) engaged with the driving wheel ( 25 ) and an output axle ( 271 ) of the fly wheel ( 27 ), and   a link unit ( 3 ) having a driving plate ( 31 ), a first link ( 32 ), a second link ( 33 ), a third link ( 34 ), a fourth link ( 35 ) and a seat frame ( 36 ), the driving plate ( 31 ) having a first end secured to the shaft ( 24 ) and a second end of the driving plate ( 31 ) pivotably connected with a first end of the first link ( 32 ), a second end of the first link ( 32 ) secured to a first end of the second link ( 33 ), a second end of the second link ( 33 ) secured to a first end of the third link ( 34 ), a second end of the third link ( 34 ) pivotably connected to the transverse bar ( 13 ), a first end of the fourth link ( 35 ) pivotably connected to the transverse bar ( 13 ), the seat frame ( 36 ) pivotably connected with the second link ( 33 ) and a second end of the fourth link ( 35 ).   
   
   
       2 . The device as claimed in  claim 1 , wherein the link unit ( 3 ) is driven by the transmission unit ( 2 ) which drives the driving wheel ( 25 ) so as to drive the link unit ( 3 ). 
   
   
       3 . The device as claimed in  claim 1 , wherein the seat frame ( 36 ) includes a seat ( 37 ) and two handles ( 361 ) are located on two ends of the seat ( 37 ), the seat frame ( 36 ), the second link ( 33 ), the third link ( 34 ) and the first link ( 32 ) are moved downward when a user sits on the seat ( 37 ) and the downward movement moves the driving plate ( 31 ) to rotate the shaft ( 24 ) which rotates the driving wheel ( 25 ) and the link ( 23 ). 
   
   
       4 . The device as claimed in  claim 1 , wherein a case ( 4 ) is mounted to the base ( 1 ) and two respective dust covers ( 5 ) are mounted to the second link ( 33 ) and the fourth link ( 35 ). 
   
   
       5 . The device as claimed in  claim 1 , wherein the frame ( 11 ) includes two side plates ( 111 ) on two sides thereof and the output axle ( 271 ) of the fly wheel ( 27 ) is engaged with the two side plates ( 111 ). 
   
   
       6 . The device as claimed in  claim 1 , wherein a connection plate ( 214 ) is connected to the pedal frame ( 21 ) and the first end of the crank ( 22 ) is pivotably connected to the connection plate ( 214 ). 
   
   
       7 . The device as claimed in  claim 1 , wherein a disk ( 241 ) is fixed to the shaft ( 24 ) and connected to the driving wheel ( 25 ). 
   
   
       8 . The device as claimed in  claim 1 , wherein the second end of the third link ( 34 ) is pivotably connected to a rear end of the transverse bar ( 13 ) and the first end of the fourth link ( 35 ) is pivotably connected to a front end of the transverse bar ( 13 ). 
   
   
       9 . The device as claimed in  claim 1 , wherein the tilt bar ( 14 ) includes a through hole ( 141 ) and the shaft ( 24 ) extends through the through hole ( 141 ), two protrusions ( 142 ) extending from two sides of the tilt bar ( 14 ). 
   
   
       10 . The device as claimed in  claim 9 , wherein the pedal frame ( 21 ) is an H-shaped frame and the securing portion ( 211 ) is a U-shaped. 
   
   
       11 . The device as claimed in  claim 10 , wherein the U-shaped securing portion ( 211 ) includes two connection holes ( 212 ) with which the protrusions ( 142 ) on the tilt bar ( 14 ) are engaged.
