The present invention relates to a hula hoop, and more particularly to a hula hoop configured to be adjustable in size.

In general, a hula hoop is a ring-shaped tube made of a pipe-type synthetic resin material, which is a kind of playful ball that causes the tube to rotate around the waist by centrifugal force by rotating the waist while it is wrapped around the waist of the human body.

The hula hoop has to be returned to the body quickly if the diameter is small, and the body can be turned slowly as the diameter is larger. Hula hoops of various sizes are manufactured according to the purpose and purpose of use, and the specifications of the hula hoop for children and the hula hoop for children are different.

However, the conventional hula hoop has a problem that it is not possible to adjust the size of the hula hoop, so if a hula hoop of various sizes is required, the hula hoop must be purchased for each required size, and the size of the hula hoop cannot be reduced, so it is not easy to store in a narrow space.

The present invention has been made to solve the problems of the prior art, the present invention is to provide a hula hoop to adjust the diameter of the hula hoop.

The present invention for achieving the above object is a circular ring-shaped hula hoop, the predetermined portion of the hula hoop is made of a flexible connection structure, the elastic connection structure is formed in the insertion hole and the insertion hole in the circumferential direction of the hula hoop In the circumferential direction of the hula hoop comprises an insertion fastening portion which is inserted into the insertion hole to enable the sliding movement, thereby changing the depth of inserting the insertion fastening portion into the insertion hole is configured to change the diameter of the hula hoop.

In addition, the side of the insertion fastening portion is provided with an elastic protrusion protruding outward, the side of the insertion hole is provided with a plurality of projection holes of the size corresponding to the elastic protrusions formed at intervals in a line, the elastic The protrusion is retractable inwardly so as to move the insertion fastening portion in the insertion hole, and when the position coincides with the protrusion hole, the protrusion is expanded so as to be inserted into the insertion hole and caught. It is preferably configured to be able to contract by pressing with a finger in the state inserted in the.

In addition, the elastic protrusion is preferably elastically supported by a spring installed inside the insertion fastening portion.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1, the hula hoop according to the present invention is made of a tubular body in the form of a circular ring.

A portion of the hula hoop 100 has a stretchable connection structure 200. The flexible connection structure 200 refers to a structure formed to enable the length adjustment in which the insertion fastening portion 210 is movably inserted into the insertion hole 220. The part with the flexible connection structure 200 of the hula hoop 100 according to the present invention is disconnected in that it is not integrally formed while maintaining the connection in the manufacturing process, but one end that is disconnected from each other is inserted into the other end. Since the hula hoop 100 is a continuous continuous ring-shaped form as a whole.

The insertion hole 220 is not formed by digging holes separately because the hula hoop 100 itself is made of a tubular body, and is naturally formed when any one of the hula hoops 100 is broken. Since the insertion fastener 210 should be inserted into the insertion hole 220, the diameter of the insertion fastening portion 210 is slightly smaller than the diameter of the portion of the tubular body constituting the other hula hoop 100, but the difference is the seam when the hula hoop 100 is used. Is not big enough to make you feel uncomfortable.

FIG. 2 is an enlarged cross-sectional view of part A of FIG. 1.

Four protrusion holes 230 are formed in a line in the wall surrounding the insertion hole 220, and the elastic protrusion 240 having a size that fits into the protrusion hole 230 bounces outward from the insertion fastening part 210. Listed. When the hula hoop 100 is normally used, the elastic protrusion 240 is inserted into the protrusion hole 230 and locked, and thus the insertion fastening portion 210 may not move freely from the insertion hole 220.

When the elastic protrusion 240 is pressed in and removes the pressed force, the spring 250 is elastically supported at the bottom surface of the elastic protrusion 240 so that the elastic protrusion 240 is restored to its original state and pops out again. The spring 250 is supported by a cylindrical spring support 260 formed in the internal space of the insertion fastening portion 210.

3A and 3B illustrate a state of the flexible connection structure 200 in the process of changing the length of the hula hoop 100.

When the user presses the elastic protrusions 240 inserted into the protrusion holes 230 with the fingers through the protrusion holes 230 from the outside, the user holds both sides of the stretchable connection structure 200 by hand and pulls or pushes the protrusion holes ( The elastic protrusion 240 fitted to the 230 is moved inward so as not to get caught in the periphery of the protrusion hole 230 so as to be movable. In order to facilitate this operation, as shown in FIG. 3A, the upper end of the protruding hole 230 is rounded and the lower end of the protruding hole 230 is inclined.

When the insertion fastening part 200 moves as shown in FIG. 3B and the position of the elastic protrusion 240 coincides with the position of the protrusion hole 230, the elastic protrusion 240 is inserted into the protrusion hole 230 and fixed. This process is performed one or more times to change the diameter of the hula hoop 100 by inserting or inserting the insertion fastening part 200 deeper into the insertion hole 220.

Even if the diameter of the hula hoop 100 is changed, since the material of the hula hoop 100 is elastic to some extent and deformable, the hula hoop 100 continuously maintains a circular ring shape.

As described above, the present invention has been described only with respect to specific examples, but it is apparent to those skilled in the art that various modifications and changes can be made within the technical spirit of the present invention based on the specific examples above. Of course, it belongs to the utility model registration claim attached to the modification.

As described above, according to the hula hoop according to the present invention can change the diameter of the hula hoop within a certain range it can be used to properly adjust the size of the hula hoop according to the age of use and to adjust the size of the hula hoop to the user's desired exercise effect It can also be adjusted and the size of the hula hoop can be reduced, so it can be effectively stored in a narrow space.
