- Referring to
FIG. 1 to 7 , a hula-hooping device according to an embodiment of the invention is illustrated. The hula-hooping device includes alower case 12 and anupper case 11, which have the form of a disk. Thelower case 12 is provided with anut pipe 12 a protruded at the center thereof. Theupper case 11 is provided with aconnection hole 11 a formed at the center thereof. - The
nut pipe 12 a of thelower case 12 passes through and is then coupled with theconnection hole 11 a of the upper case. The upper andlower cases like case 10 having a circular space formed thereinside. Here, the circular space means a space inside of which a movable-object such as aball 20 received inside of thecase 10 can perform a circular motion. For example, it may include a circular-shaped space where the inner face has an equal distance from the center, an oval-shaped space, a hook-like annular space, a spherical space, a disk-shaped space, and an egg-shaped space. Theconnection hole 11 a is covered with acover 13 and combined with it. Thecover 13 has abolt 13 a protruded at its center. Thebolt 13 a is connected to thenut pipe 12 a passing through theconnection hole 11 a. Here, thenut pipe 12 a is referred to as a first thread portion and thebolt 13 a as a second thread portion. The size of thecase 10 may be made into small, medium and large ones for children, and small, medium and large ones for adults. - The
case 10 is provided at one side thereof with aU-shaped hanger 14. As shown inFIG. 7 , thehanger 14 is configured to be hung on thebelt 30. Formed at both sides of thehunger 14 is alatch plate 14 a round-bent towards thecase 10. Thelatch plate 14 a prevents the device from being released from thebelt 30 and functions to allow the device to smoothly and resiliently contact the user's body while wobbling to the left and right when he or she exercises. Abuffer member 15 is attached to the inner side of thehanger 14 to provide for a smooth contact with the user's body and thus improve its wearing comfort. - A
weight ball 20 is accommodated inside of thecase 10. Theweight ball 20 is a movable-object that carries out a circular motion inside of thecase 10 as thecase 10 moves. Preferably, theweight ball 20 is formed of a metallic material such as steel or lead. The weight ball may be made of other materials such as stone, highly-compressed paper, compressed synthetic resin or the like. The outer surface of theball 20 may be coated with soft rubber or synthetic resin to reduce noises when theball 20 circulates. - In the drawings,
unexplained reference 16 denotes a packing interposed between the upper andlower cases Unexplained reference 31 denotes a synthetic resin buckle combined to thebelt 30. - The hula-hooping device having the above construction is designed such that a user can wear it on the waist by way of the
belt 30. If the user wears the hula-hooping device on his or her waist and then moves his or her waist in a circle motion, theweight ball 20 received in thecase 10 turns around along the inner circumference of thecase 10 by means of centrifugal force. As the waist moves fast, the ball speed becomes fast, so that the centrifugal force becomes stronger, thereby producing an exercise effect of doing a hula-hoop. - On the other hand, as shown in
FIG. 3 , in addition to theweight ball 20, a liquid 21 such as water, orparticles 22 such as synthetic resin particles may be injected so as to turn around, along with theweight ball 20. At this time, movable-objects such as the liquid 21 or theparticles 22 circulates with theball 20 to thereby increase rotational resistance. Theweight ball 20 heavier than the liquid 21 or theparticles 22 tends to move faster, passing the liquid or particles, which results in a dual-resistance, thereby generating a different exercise effect. - In addition, a user can wear multiple hula-hooping devices, i.e., one to four or more, depending upon his or her physical stamina.
- Referring to
FIG. 2 , a plurality ofprotrusions 10 a is formed in the inner circumference of thecase 10. Theseprotrusions 10 a contact with theball 20, when it moves, to thereby produce vibration. - Referring to
FIG. 8 , instead of theprotrusions 10 a formed inside of the upper andlower cases protrusions 16 c may be formed in the inner circumferential face of aprojection part 16 b of the packing 16 a in such a way to protrude towards the inner space of thecase 10. Remaining details are the same as inFIGS. 1 to 7 . - Referring to
FIG. 9 , thelower case 12 is provided with afemale latching hole 12 b formed along the edge thereof and theupper case 11 is provided with amale latching protrusion 11 b, or vice versa. These male and female latching elements are combined with each other to form thecase 10. In some cases, as shown inFIG. 10 , theupper case 11 is provided with amale thread 11 c formed in the outer surface thereof and thelower case 12 is provided with afemale thread 12 c formed in the inner surface thereof, or vice versa. These male and female threads can be coupled to each other to form thecase 10. - Referring to
FIG. 11 , thelower case 12 may be provided with a threadedprotrusion 12 d formed at the center thereof. The threadedprotrusion 12 d has a thread portion formed in the outer peripheral face thereof. Formed at the center of theupper case 11 is anut portion 11 d to be combined with the threadedprotrusion 12 d so as to form thecase 10. The threadedprotrusion 12 d and thenut portion 11 d can be switched over with each other. - Besides, the upper and lower cases may be combined with each other through various other connecter means. Furthermore, in case where the case is made of metallic materials, the upper and lower cases can be connected to each other through a welding process, or a fusion bonding, or application of adhesives to form a single body case.
- Referring to
FIG. 12 , according to an embodiment of the invention, the hula-hooping device may be applied to a user's leg or thigh by using ashorter belt 30, thereby facilitating exercises for the legs or lower torso of human body. Besides the leg, it can be used for other part of human body such as arm and the like. - As shown in
FIG. 13 , thecase 10 may be formed into an oval shape, or in some cases, a spherical shape. - As described above, according to the invention, the hula-hooping device can be used in a narrow confined space for hula-hoop exercise.
- In addition, the belt can be received into the case, thus providing a good portability.
- The hula-hooping device of the invention provides for a new type of hula-hoop exercise, which is totally different from the convenient ones. Further, due to the ball and protrusions inside of the case, vibration is generated to smoothly massage the user's waist area.
- While the present invention has been described with reference to several exemplary embodiments, the description is illustrative of the invention and is not to be construed as limiting the invention. Various modifications and variations may occur to those skilled in the art, departing from the scope of the invention as defined by the appended claims.
