Rotary exercise apparatus

Abstract

Provided is a rotating sports apparatus capable of keeping safety even if the user has protruding limbs or the like. The rotating sports apparatus comprises a contour frame ( 2 ) forming a regular icosahedron, ball members ( 3 ) rotatably supported individually at the outer side positions of the individual vertices of the icosahedron of the contour frame ( 2 ), and a pedestal ( 5 ) having a hemispherical face ( 4 ) inscribing the balls ( 3 ) of the contour frame ( 2 ). The rotating sports apparatus keeps predetermined spaces between the individual faces of the contour frame ( 2 ) and the hemispherical face ( 4 ). Thus, the rotating sports apparatus can keep the safety, even in case the limbs or the like of the user (P) protrude more or less during a practice from the individual faces of the contour frame ( 2 ).

1 . A rotary exercise apparatus comprising:
 a contour frame defining a regular polyhedron;   balls each rotatably supported at a position outside of each of vertices of said contour frame defining a regular polyhedron; and   a pedestal having a semispherical surface inscribing said balls of said contour frame therein, and rotatably supporting said contour frame therein.   
   
   
       2 . The rotary exercise apparatus as set forth in  claim 1 , wherein said polyhedron is a regular icosahedron or a regular dodecahedron. 
   
   
       3 . The rotary exercise apparatus as set forth in  claim 2 , further comprising:
 a feet fixture for fixating feet of a user at a position inside of a frame of said contour frame defining a regular icosahedron or a regular dodecahedron; and   a hands fixture for fixating hands of said user at a position inside of a frame disposed in facing relation to said frame at which said feet fixture is arranged.   
   
   
       4 . The rotary exercise apparatus as set forth in  claim 3 , further comprising:
 a protection ring for restricting an area in which a body of said user moves, said protection ring being arranged within a plane perpendicular to a plane including said frame at which said feet fixture is arranged and said frame at which said hands fixture is arranged;   a belt wound around a body of said user within said protection ring; and   a rope for connecting said protection ring to said belt.
