DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] The exercising device according to the present invention is a waist exercising device comprising a supporting board 10 with a plurality of acupressure projections 11 on the upper side and two rotating board stopping devices 20, 20′ at both lower sides, the rotating board stopping devices 20, 20′ including each bent operating rod 21, 21′ connected and operated by springs 22, 22′ and upholding strips 23, 23′ at both sides, a rotating board 30 located in the upper center of the supporting board 10, the rotating board 30 having a plurality of acupressure projections 31 on the upper side and a plurality of holes 32 at the lower side of the outer circumference, a circular board 50 located in the upper center of the rotating board 30, the circular board 50 moving upwardly and downwardly on both upholding bars 40, 40′ by both supporting implements 100, 100′ at both sides, a plurality of tension springs 61 and a plurality of rollers 63 with a plurality of acupressure projections 62 on the outer surface fixed between the upper backing board 70 and lower backing board 71 with a plurality of connecting rods 73, combination rods 74 and holes 75 in regular spaces, respectively, two combination implements 80, 80′ fixed to the circular board 50, the combination implements 80, 80′ inserted by upholding bars 40, 40′, and the combination implements 80, 80′ including stoppers 82, 82′ with grips 41, 41′ and springs 83, 83′, which are to be engaged with linear ratchets 90, 90′ on both upholding bars 40, 40′ according to upward and downward movements of the rotating board 30, and two upholding bars 40, 40′ located inside the supporting implements 100, 100′, the upholding bars 40, 40′ including two grips 41, 41′ on top of the both bars, and the linear ratchets 90, 90′, which are to be engaged with the stoppers on the combination implements 80, 80′, and two linear ratchets 90, 90′ fixed to the both upholding bars 40, 40′ by screws 91 and engaged by the stoppers 82, 82′.

[0029] The numerals 76 refers to screws, 110 to bearing, 200, 200′ and 200″ to acupressure projections, 300, 300′, 300″ to backing strips, and 400 to a loop.

[0030] As shown in FIG. 13, users do the waist exercise by rotating the waist in the left and right directions repeatedly, with standing on a plurality of acupressure projections 31 of the rotating board 30 inserted in the center of the supporting board 10 connected to the supporting implements 100, 100′ and holding one of the grips 40, 40′ of the upholding bars 40, 40′ with both hands. If users rotate their waists in the left and right directions, the rotating board 30 rotates according to rotations of the bearing 110 inside the rotating board 30, and it is helpful for users to increase the waist pliability. In this case, since the circular board 50 placed on the supporting board 10 presses the both ends of the operating rods 21, 21′ extended outwardly from the holes of the upper surface of the supporting board 10, the both ends of the operating rods 21, 21′ are not inserted into a plurality of holes on the lower surface of the rotating board 30. Therefore, the rotating board 30 rotates left or right freely according to the movements of the users.

[0031] If users want to do another kind of the waist exercise or abdominal preventing exercise, and lift the circular board 50 placed on the supporting board, as shown in FIG. 14. In case that users lift the circular board 50 upwardly, the rotating board stopping devices 20, 20′ work at the same time as shown in FIG. 6. In other words, the operating rods 21, 21′ rotate in the backing strips 23, 23′ by the springs 22, 22′ connected to the operating rods 21, 21′. Since the both ends of the operating rods 21, 21′ are extended outwardly from the holes of the upper surface of the supporting board 10, as shown in FIG.4, the both ends of the operating rods 21, 21′ are inserted inside the holes on the lower surface of the rotating board 30 and the rotating board 30 is fixed without turning at the same time.

[0032] When users lift the circular board 50 upwardly, with standing on the rotating board 30 which does not rotate, users hold the grips 81, 81′ of the combination implements 80, 80′ fixed to the circular board 50 by backing strips 300, 300′ and inserted by the upholding bars 40, 40′, and lift the grips 81, 81′ of the combination implements 80, 80′ to the linear ratchet 90, 90′ connected to upper parts of the upholding bars 40, 40′ by the screw 91, at the height of the waists of the users or at the positions where users want to fix the circular board 50, and then place the grips 81, 81′ as shown in FIG. 6. If users place the grips 81, 81′ users are lifting at the height of the waists of the users, the stoppers 82, 82′ placed on the upper side of the grips 81, 81′ are engaged with one of the projections of the linear ratchet 90, 90′.

[0033] After lifting the circular board 50 at the height of the waist, users rotate their waists around the inner circular board 50 in the left, right, front and rear directions. As shown in FIG. 5, the above circular board 50 in which the rollers 63 are inserted by a plurality of connecting rods 73, the loop 400 is inserted through the circular board 50, and the tension spring 61 is inserted by the combination rod 74, rotates around the waists of the users, with being fixed between the upper supporting board 70 and lower supporting board 71 by the screw 76. According to rotations of the circular board 50 in the left, right, front and rear directions by the waist rotating of the users, a plurality of rollers 63 with a plurality of acupressure projections on the outer surface pressure-stimulate, and massage the waists by shrinking and expansion of a plurality of the tension springs 61 inside the upper supporting board 70 and lower supporting boards 71 in the opposite direction to the rotation of the circular board 50. For example, when users rotate the circular board 50 in the left side by the rotating their waists, the tension springs 61 in the left side are shrinking but the tension springs 61 in the right side are expanding as shown in FIG. 9. FIGS. 10, 11, and 12 show the cases of rotations of the circular board in front, right and rear directions, respectively.

[0034] After finishing the above exercises, when the user return the circular board 50 to the first position, the user holds the grips 81, 81′ and stoppers 82, 82′ at the same time and press them and then the springs 83, 83′ are shrinking and detached from the projections of the ratchet 90, 90′. And then user lowers the circular board 50 downwardly to the upper side of the supporting board 10.

[0035] FIG. 15, and 16 are another embodiments of the present invention, and show a waist exercising tool 1″ which has another upholding bar 40″ with a grip 41″ on the other side of the supporting implement 100″ and the combination implement 80″ attached to one side of the circular board 50. The embodiment has more safety and endurance than the device which has only two upholding bars 40, 40′.
