80: protective cover [Mode for Invention] The movable body 50 and the outer ring 10 may be coupled with each other in various ways .

For an example of the connected form, as shown in FIGS. 9 and 10, the movable body 50 surrounds the outer ring 10 in the form of an alphabet letter "C" and has protrusions 52 formed on upper and lower end portions thereof. The protrusions 52 are in line contact or point contact with the inner periphery of the outer ring 10. FIG. 9 shows the inner periphery of the outer ring 10, which is in a flat form, and FIG. 10 shows the outer ring 10 which has a concave formed on the inner periphery thereof.

In the case where the protrusions 52 are in line contact with the outer ring 10, the protrusions 52 are formed long in a longitudinal direction of the movable body 50, but in the case where the protrusions 52 are in point contact with the outer ring 10, the protrusions 52 are formed at regular intervals in the longitudinal direction of the movable body 50,

FIG. 11 is a perspective view of the movable body 50 in the latter case.

For another example, as shown in FIG. 12, the movable body 50 or the outer ring 10 includes a guide groove 56, and the movable body 50 or the outer ring 10 which does not have the guide groove 56 includes a guide protrusion 17 inserted into the guide groove 56.

For a further example, as shown in FIG. 13, the outer ring 10 is in the form of an alphabet letter "H", and the protrusions 52 of the movable body 50 are inserted and fit into the outer ring 10.

For another example, as shown in FIG. 14, the outer ring

10 is in the form of an alphabet letter "C" which is opened at the outer side thereof, and the movable body 50 is in the form of an alphabet letter "H" inserted and fit into the outer ring

10. The movable body 50 is in line contact or point contact with the outer ring 10.

The above coupling forms between the outer ring 10 and the movable body 50 are to rotate the movable body 50 in a state where the movable body 50 is in direct contact with the outer ring 10. In these cases, the protrusions 52 of the movable body 50 may be abraded. Therefore, to reduce the abrasion, a bearing 53 may be used. In FIGS. 15 and 20, the movable body 50 surrounds the outer ring 10, has protrusions 52 formed at upper and lower end portions thereof, and is formed in a "^" shape, and the bearing 53 which is in contact with the inner periphery of the outer ring 10 is coupled to the protrusion 52. Then, the movable body 50 is in contact with the inner periphery of the outer ring 10 through the bearing 53, so that the movable body 50 can be smoothly rotated without abrasion.

At this time, the bearing 53 may be a thrust bearing or a ball bearing. In this specification, just the thrust bearing and the ball bearing are mentioned, but another well-known bearing may be used.

FIGS. 15 to 17 show examples where the thrust bearing is used. As shown in the drawings, the thrust bearings are coupled to ends of the upper and lower protrusions 52, and the bearings 53 are in contact with the inner periphery of the outer ring 10. FIG. 15 shows a case where the outer ring 10 is in the form of an alphabet letter "D" having a section with an expandable inside and a protruding outside. In this case, it is preferable that the outer ring 10 includes guide grooves 16 and the bearings 53 of the movable body 50 are respectively inserted into the guide grooves 16.

The bearing 53 is fixed by a boss 54 and elastically supported by a spring 55. To separate the movable body 50 from the outer ring 10, when the bearing is moved backwardly, the boss 54 is also moved backwardly, and then, when the movable body 50 is turned over, the movable body 50 can be separated from the outer ring 10. Furthermore, since the bearing 53 is elastically supported by the spring 55, the movable body 50 can be returned to its original position. To couple the movable body 50 with the outer ring 10, in a state where the bearings 53 are moved backwardly, the movable body 50 is coupled with the outer ring 10.

FIG. 16 shows a state where the bearings 53 are in contact with the inner periphery of the outer ring 10 and with the upper periphery of the outer ring 10. Then, the movable body 50 is drooped by weight of the weight body 70 inserted into the movable body 50, whereby the movable body 50 can be smoothly rotated without interference between the movable body 50 and the outer ring 10. In FIG. 17, the outer ring 10 is in the form of a fan having a section with an expanded outside and a protruding inside. In this case, the bearing 53 may be fixed by the boss 54 and elastically supported by the spring 55.

FIGS. 18 to 20 show examples of a ball bearing. In FIG. 18, the outer ring 10 is in the form of a fan having a section with an expanded outside and a protruding inside. The inner periphery of the outer ring 10 is in point contact with the ball bearings 53 mounted on the inner peripheries of ends of the protrusions 52 of the movable body 50. At this time, the protrusion 52 located on the upper portion of the movable body 50 is hingedly fixed. After that, to separate the movable body 50 from the outer ring 10, a fixing piece 56, which is hingedly fixed, is rotated to release the fixed state, and then, the protrusions 52 of the movable body 50 are rotated.

In FIG. 19, the outer ring 10 includes guide grooves 16 formed on the upper and lower peripheries thereof, and the ball bearings, which are mounted at the ends of the protrusions 52 of the movable body 50, are in point contact with the guide grooves 16.

In FIG. 20, the outer ring 10 includes guide grooves 16 formed on the upper and lower portions of the inner periphery thereof, and the ball bearings, which are mounted at the ends of the protrusions 52 of the movable body 50, are in point contact with the guide grooves 16.

In FIGS. 18 to 20, like FIG. 17, the protrusion 52 located on the upper portion of the movable body 50 is hingedly fixed on the movable body 50, and fixed to the movable body 50 via a fixing piece 56. To separate the movable body 50 from the outer ring 10, the fixing piece 56 is released, and the protrusions 52 of the movable body 50 are rotated.

The abdominal exercise tool according to the present invention further includes a timer mounted on the outer ring 10 or the inner ring 30 for checking an exercising period of time, and a speed meter or a counter mounted on the outer ring 10 for checking rotational speed and rotational frequency of the movable body 50.

The abdominal exercise tool according to the present invention having the above configuration provides a weight reduction effect through a concentrative aerobic exercise of the abdomen since it enables the user to rotate the user's waist at various angles in a state where the user grasps a grip member 6 with both hands .

For example, FIG. 21 shows an example that the user locates the major axis of the elliptical outer ring 10 on the right and left of the user so as to increase the weight reduction effect of the center of the abdomen, but FIG. 22 shows another example that the user locates the major axis of the outer ring 10 on the front and rear of the user so as to increase the weight reduction effect of the user's side. Furthermore, FIG. 23 shows another example that the user locates the major axis of the elliptical outer ring 10 in an oblique line direction from the user's front to rotate the user's waist in the oblique line direction so as to increase the weight reduction effect of the central portion between the center of the abdomen and the side. According to circumstances, the user may take a waist exercise while grasping the grip upward with one hand and downward with the other hand, and make the abdominal exercise tool vertically move in the oblique line direction when the user lifts up or lowers one hand, whereby the movement range is maximized so as to enhance the weight reduction effect of the user's waist.

In the above embodiments, the weight body 70 is inserted into the movable body 50, but as shown in FIGS. 18 to 20 and 24, the weight body 70 can be coupled with the movable body 50 via a boss 71.
