Ball exercise equipment

Abstract

Disclosed is ball exercise equipment including: a neck strap ( 4 ); an adjustment string ( 3 ); and an adjusting unit ( 2 ), wherein a ball ( 8 ) is connected at one end of the adjustment string ( 3 ).

What is claimed is: 
     
         1 . A ball exercise equipment comprising:
 a neck strap ( 4 ); an adjustment string ( 3 ); and an adjusting unit ( 2 ),   wherein a ball ( 8 ) is connected at one end of the adjustment string ( 3 ),   wherein the adjusting unit ( 2 ) is provided between neck strap ( 4 ) and the other end of the adjustment string ( 3 ) and adjusts a length of the adjustment string ( 3 ),   wherein a receiving space ( 204 ) is provided in the adjustment unit ( 2 ),   wherein the adjustment string ( 3 ) is drawn out of the adjustment unit ( 2 ) along a wall of the receiving space ( 204 ),   wherein a rotating shaft ( 208 ) is provided in a center of the receiving space ( 204 ),   wherein a winding reel ( 250 ) is coupled to the rotation shaft ( 208 ),   wherein the length of the adjustment string ( 3 ) is adjusted in such a manner that the adjustment string ( 3 ) is wound around or loosened from the winding reel ( 250 ),   wherein a rotation restriction unit is provided in the adjusting unit ( 2 ) which restricts a rotation of the winding reel ( 250 ),   wherein the rotation restriction unit secures the adjustment string ( 3 ) to a given length by preventing the adjustment string ( 3 ) from being wound or being loosened unintentionally.   
     
     
         2 . The ball exercise equipment of  claim 1 ,
 wherein the rotation restriction unit includes a lever ( 270 ) which is rotatably provided on an edge of the winding reel ( 250 ),   wherein a concave locking groove ( 219 ) extends from the receiving space ( 204 ) to an outside of the adjustment unit ( 2 ),   wherein when the lever ( 270 ) is inserted into the concave locking groove ( 219 ), the rotation of the winding reel ( 250 ) is restricted so that the adjustment string ( 3 ) is fixed to the given length and is prevented from being wound or being loosened unintentionally.   
     
     
         3 . The ball exercise equipment of  claim 2 ,
 wherein a compression spring ( 216 ) is provided in the concave locking groove ( 219 ),   wherein a compression spring ( 216 ) elastically presses a side of the lever ( 270 ).   
     
     
         4 . The ball exercise equipment of  claim 1 ,
 wherein the ball ( 8 ) is rotatably connected to the adjustment string ( 3 ) so that the adjustment string ( 3 ) is not twisted while the ball ( 8 ) rotates.   
     
     
         5 . The ball exercise equipment of  claim 1 ,
 wherein the rotation restriction unit includes a locking unit ( 290 ),   wherein a concave sliding groove ( 229 ) extends from the receiving space ( 204 ) to an outside of the adjustment unit ( 2 ),   wherein the locking unit ( 290 ) is inserted in the concave sliding groove ( 229 ) and moves back and forth to the receiving space ( 204 ),   wherein a locking groove ( 252 ) is provided on an upper surface of the winding reel ( 250 ) and extends from an edge of the winding reel ( 250 ) toward a center of the winding reel ( 250 ),   wherein a locking protrusion ( 292 ) extends from the locking unit ( 290 ) towards the locking groove ( 252 ),   wherein the locking protrusion ( 292 ) is selectively fitted into the locking groove ( 252 ) according to the back and forth movement of the locking unit ( 290 ), whereby rotation of the winding reel ( 250 ) is controlled.   
     
     
         6 . The ball exercise equipment of  claim 5 ,
 wherein the locking groove ( 252 ) includes multiple grooves which are radially arranged with each other.   
     
     
         7 . The ball exercise equipment of  claim 5 ,
 wherein the locking unit ( 290 ) is provided with an elastic spring ( 296 ),   wherein the elastic spring ( 296 ) returns the locking unit ( 290 ) to a given original position of the locking unit ( 290 ).   
     
     
         8 . The ball exercise equipment of  claim 5 ,
 wherein a handle protrusion ( 254 ) is provided on the upper surface of the winding reel ( 250 ),   wherein the winding reel ( 250 ) is rotatable by manually pushing the handle protrusion ( 254 ).
