Definitions

  • the present invention relates to a rotary exercise apparatus which a user enters and with which a user rotates for carrying out muscle training and enhancing the sense of equilibrium.
  • each of the rotary exercise apparatuses suggested in the patent references 1 to 3 is comprised of a gimbal comprised of three rings and supported on the ground. A user entering the rotary exercise apparatuses can rotate in any direction merely by moving his/her weight.
  • the rotary exercise apparatus suggested in the patent reference 4 includes grips disposed at an upper area in a spherical frame comprised of vertical and horizontal frames, and feet fixture disposed at a lower area both in a spherical frame comprised of vertical and horizontal frames.
  • a plurality of hard balls is rotatably mounted over an outer surface of the frame defining a sphere.
  • the spherical frame is rotatably mounted on a pedestal having a semispherical recessed surface corresponding to a semispherical outer surface of the spherical frame.

  • the user P puts the wrist bands 7 c around his/her wrists, and grasps the grips 7 a during exercise. This ensures that even if the user P releases his/her hands off the grips 7 a, the strings 7 b and the wrist bands 7 c prevent the user's hands from protruding out of the contour frame 2 .
  • the contour frame 2 includes therein a protection ring 8 disposed in a plane including both the pipe 2 a at which the feet fixtures 6 are mounted and the pipe 2 a at which the hands fixtures 7 are mounted, and a belt 9 to be wound around the body of the user P inside of the protection ring 8 .
