Description

Magnetic assembly structure of hula hoop {MAGNET ASSEMBLY STRUCTURE OF A HULA HOOP}

The present invention relates to a hula hoop, and more particularly, to a magnet assembly structure of the hula hoop that can be assembled easily and firmly the magnet provided in the hula hoop.

Typically, the hula hoop is a tube of resin material connected in a circular shape, it is used for the purpose of flexibility and diet of the waist by turning the hula hoop using a rotation or recoil after being inserted into the waist portion. The hula hoop has a therapeutic effect of low back pain by assisting acupressure and blood circulation while giving a protrusion or attaching a magnet to the inside. Refer to Utility Model Registration No. 179339 (adhesive acupressure protrusion provided on the hula hoop) as one example of the design of a hula hoop that has such a purpose, that is, a number of wires with protrusions and magnets attached to the inside of the hula hoop. , It has a circular groove in the center of the acupressure protrusion attached to the inner surface of the hula hoop and is fixed to the magnet by the circular groove. However, the wire design needs to apply an adhesive to the contact portion between the circular groove and the magnet because the magnet is easily detached during use. Therefore, not only is it inconvenient to consume the adhesive and waste of manpower, but also the adhesive force of the adhesive does not prevent the magnet from detaching and causes a phenomenon that the magnet is still detached from the hula hoop after a long time use.

And as another example, according to Utility Model Registration No. 188618 (hula hoop) that is published in the Republic of Korea Patent Office, it is lacking in durability as the projection (hem) is attached adhesively along the inner surface of the hula hoop, The magnet is inserted into the formed hole, but a protrusion for preventing the magnet from being detached has a problem of being difficult to manufacture.

The present invention is to overcome the above-mentioned conventional problems, to provide a magnet assembly structure of the hula hoop that is easy to assemble and strong and can prevent the attached magnet detached.

In order to achieve the above object, the present invention is to be integrally formed at regular intervals along the inner surface of the hula hoop, the assembly portion 30 is formed with a hole in the center and a locking jaw at the top, and fitted into the assembly portion It has a hole in the center and is formed with a cap 24 having a locking jaw formed in the inside of the hole, the assembly portion and each hole of the cap, the upper portion is characterized by consisting of an insert 10 is assembled with a magnet.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing the present invention, if a detailed description of a related known function or configuration may obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is an exploded perspective view illustrating a state assembled according to the magnet assembly structure of the present invention hula hoop, Figure 2 is a central cross-sectional view of the state assembled according to the present invention. According to the drawings, protrusions 2 are formed at regular intervals along the inner surface of the hula hoop, and the assembly 30 is formed on the protrusions. The assembly portion is assembled with a hemispherical cap 24 and is provided with an insert 10 for binding the assembly portion and the cap.

The above is described in more detail as follows.

First, a smooth curved protrusion 2 is formed on the inner surface of the hula hoop 1 which is circularly completed while connecting a ring body connecting both ends in one pipe, or a plurality of pipes divided into one another. . The protrusion may be formed at an appropriate height depending on the effect of the pressure, but may be omitted. And the center of the protrusion is provided with an assembly portion 30 in which the circular frame 31 and the protruding edge 38 is integrally molded with the hula hoop. The frame 31 has a hole 32 in the center thereof, and a locking jaw 34 is formed at an upper end thereof, and a protruding edge 38 is formed outside the frame 31. At this time, the seating groove 36 is formed while having a predetermined interval between the assembly portion 30 and the protruding edge 38. On the other hand, the cap 24 is coupled to the assembly portion 30 is a hemispherical shape has a hole 26 in the center and the locking jaw 28 protruding inward in the inner middle point is formed. In addition, the frame 31 of the assembly unit 30 is fitted from the lower portion of the hole 26 to contact the upper locking jaw 34 of the frame 31 and the locking jaw 28 of the cap 24. Thereafter, the insert 10 is fitted between the caps 24 and the holes 26 and 32 of the frame 31. At this time, the insert is formed of the upper head 12 and the lower body 16 is integrally formed, the inside of the head 12 is a hole 14 is formed and one side is opened while the magnet 22 is fitted. And, in the middle of the body 16, the protruding jaw 18 is formed on both sides and forms a slope as the height thereof gradually decreases downward. When the body 16 is fitted into the cap 24 and the frame 31, the locking jaw 28 of the cap and the locking jaw 34 of the frame 31 are inserted between the head 12 and the protruding jaw 18. You lose. At this time, a rectangular hole 20 is formed in the center of the body 16 and elastically contracted when an external pressure is applied to the protruding jaws 18 on both sides. Accordingly, the protruding jaw 18 can be easily assembled while being elastically fitted into the cap 24 and the hole 32 of the frame 31, while the protruding jaw 18 is the locking jaw of the frame 31. It will not be easy to fall off.

By the above configuration, the magnet assembly structure of the hula hoop according to the present invention is assembled as follows.

First, the lower portion of the cap 24 is assembled to the outside of the frame 31 of the assembly portion 30 to be assembled. At this time, the lower end of the cap is fitted into the inner side of the protruding edge, that is, the seating groove 36. Then, the magnet 22 is inserted into the head 12 of the insert 10, and then the body 16 of the insert 10 is inserted into the hole 26 of the cap 24. At this time, the protruding jaw 18 of the insert 10 is caught on the engaging jaws 28 and 34 of the cap 24 and the frame 31, but if the upper part of the head is applied with a predetermined pressure, the protruding sides As the jaw 18 is pushed inward through the central hole 20, the jaw 18 passes through the locking jaw 34 of the frame 310. Therefore, the jaw 18 is inserted between the head 12 and the protruding jaw 18 of the insert 10. As the locking jaw 28 of the cap 24 and the locking jaw 34 of the frame 31 are fitted, they do not easily come off, and the head 12 into which the magnet 22 is fitted is a hole 26 of the cap 24. The magnet is completely sealed while being fitted at the top.

As described above, the magnet assembly structure of the hula hoop according to the present invention can be easily assembled without the need for a separate equipment or tool, even if subjected to external shock and continuous vibration in the assembled state, as well as the magnet Each accessory will not be detached. Therefore, there is an effect that can prevent each part is damaged or lost.
