Hula hoop

Abstract

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.

1 . A hula hoop ( 1 ) in which a plurality of holes ( 8 ) are formed along on the circular edge of the main body ( 2 ) thereof, through which a plurality of projections ( 3 ) are coupled to the main body ( 2 ), in which some of the plurality of projections ( 3 ) are constructed to be slightly protruded inwardly from the inner circumferential surface of the main body ( 2 ), and the others are constructed to be substantially protruded inwardly from the inner circumferential surface of the main body ( 2 ), and in which the main body ( 2 ) is made of soft synthetic resin having a certain strength, so that the inner circumferential surface of the main body can be inverted into the outer circumferential surface thereof. 
   
   
       2 . The hula hoop according to  claim 1 , wherein the projections ( 3 ) are constructed such that the main body ( 2 ) of the hula hoop is fit between an upper body ( 4 ) and a lower body ( 5 ) of the projections, and then a bolt head portion ( 6 ) installed on the top end of the upper body of the projections is securely screwed to the main body by a screw ( 7 ).
