[Prior art]

 As modern people's life and eating and drinking diversify, past malnutrition has been caused by food deficiencies, whereas in modern times it has been caused by overeating, digestive disorders, and malnutrition. I have. On the other hand, simple exercise equipment, such as jump ropes and hula hoops, which can be enjoyed by children and adults, consumes excess fat and helps to adjust the body shape and condition.

[0003] Hula hoops are a popular outfit or exercise equipment in the past, but the market has combined a ring A "with a protruding arc inside a circular traditional simple ring A '. There are hula hoops, which are integrally molded by plastic blow molding (see Fig. 1) .The diameter of the hula hoop body is 1 inch to 1.5 inches, but the diameter of the whole ring is 30 inches to 40 inches. The dimensions were quite large, so a fairly large mold was needed.

[0004]

[Problems to be solved by the invention]

 An object of the present invention is to provide a hula hoop having a kind of rotating sphere, which is a hula hoop in which a plurality of arc-shaped units formed by plastic molding are combined, and is provided at several places inside the arc-shaped unit. The hula hoop is characterized by being provided with a protruding arc and a rotatable rotating ball placed thereon, and also capable of providing a lubrication effect by utilizing a rotating operation at the time of operation.

[0005]

[Means for Solving the Problems]

 The invention of claim 1 is characterized in that a plurality of sets of opposingly connected arcuate units are connected in series to form an annular body and the opposingly connected arcuate units. A plurality of rotating spheres are rotatably sandwiched between the streamline-projecting arcs of the arc-shaped units that are provided so as to be opposed to each other, and rotate the hula hoop and rotate the rotating spheres. The hula hoop is equipped with a rotating ball, which is characterized by providing an abrasion function.

[0006]

[Embodiment of the invention]

 FIG. 2 is a combined perspective view of the present invention. As shown, the biggest difference between the ring body A of the present invention and the known technique lies in the design of the rotating sphere 90 provided on the streamline protruding arc 50 inside the ring. The present invention is formed by combining a plurality of mutually combinable arc-shaped units by molding, and it takes extra time to assemble in manufacturing, but can significantly reduce the size of the mold. Of course, this can significantly reduce manufacturing costs.

[0007] Based on the concept of assembly rather than integral molding, the present invention is based on the idea that the arc-shaped units A1 and A2 shown in FIG. 3 are connected in a four-to-eight connection to form the circular ring shown in FIG. doing. The rotating sphere 90 is fitted between the arcuate units A1 and A2 combined with each other. The detailed structure is as shown in FIG. 5, and a plurality of hooks 10 are provided on the inner wall of one of the arcuate units A1 and A2, and the other arcuate unit A plurality of insertion hooks 20 are provided at corresponding positions on the inner wall of A2, and when the two arc-shaped units A1 and A2 are combined, sufficient engagement strength can be obtained by engagement of the insertion hooks 20 and the hooks 10. . After the combination, the two arc-shaped units A1 and A2 form one arc-shaped body 1, and the four arc-shaped bodies 1 are continuously connected to form a circular ring-shaped body A. The projections 30 and 31 and the grooves 40 and 41 are provided at both ends of the arc 1, and the locking grooves 301 and 311 are provided in the projections 30 and 31, and the locking grooves 301 and 311 and the grooves 40 and 41 are formed. The engagement between the locking portions 401 and 411 is used to position the circular body 1 when it is continuously connected, thereby preventing separation by pulling. In the present invention, a plurality of streamline-shaped protruding arcs 50 and 51 are formed inside each of the arc-shaped units A1 and A2, and rotating ball grooves 60 and 61 are provided in the arc-shaped units A1 and A2 to hold the rotating ball 90 and to rotate the rotating ball 90. The sphere 90 has a perforation 91 and the perforated column 70 of the rotating sphere groove 90 provided in the arc-shaped unit A2 penetrates the perforation 91 of the rotating sphere 90, and the rotating sphere 90 has a rotating sphere groove of the arc-shaped unit A1. 60 are sandwiched between the column grooves 80.

[0008]

[Effect of the invention]

 The present invention completes a large-sized hula hoop product by simple but tight connection by the combined arc-shaped units A1 and A2 of small-sized parts. For this reason, the cost of the mold can be greatly reduced, and various appearance products can be formed by combining arc-shaped units A1 and A2 of various colors or patterns according to the hula hoop as an entertainment product. Increase consumer choice. In addition, the present invention can provide a rubbing effect to the waist and the buttocks when used by the rotating sphere 90 installed in the streamline projecting arc, and enhance the use function of the hula hoop. Thus, it can be said that the present invention has practicality and novelty.
