| 摘要 |
The present invention relates to a hula hoop, in which a main body is made of soft synthetic resin (semisolid) so that the inner circumferential surface of the main body can be readily turned over to the outside so as to be used for both of a hula hoop provided with the higher projections thereon and a hula hoop with the lower projections thereon, as desired, thereby providing an acupressure effect which cannot be easily be compared with that of the conventional hula hoop. That is, the original shape of the hula hoop of the present invention is maintained due to a certain degree of rigidities thereof, when it is not used. However, as the turning speed of the hula hoop is gradually becoming fast, the main body thereof is rotated along an elliptical orbit due to the flexibility and elasticity thereof, so that the turning radius of the hula hoop is increased to permit a larger number of projections coupled to the hula hoop to be in contact with the body of a user, as well as to permit the body to be more strongly oppressed, thereby causing an increase in an acupressure effect applied to the body.
