HULA-HOOP

Abstract

The present invention aims to provide portability and ease of storage and mobility by allowing housing when a hula-hoop is not in use and connection in a circular form by withdrawing when in use, so as to be utilized for exercise and play. The hula-hoop comprises: a main body capable of being divided into a plurality of parts having a circular cross-sectional shape and a two-dimensional arc shape; a plurality of middle bodies which are housed in and withdrawn from one side of the main body; and an end body housed or withdrawn by being coupled to the last middle body from among the middle bodies and which connects to the other side of the main body, wherein the main body, the middle bodies, and the end body are constituted so as to be housed and withdrawn in multi-steps as in the form of an antenna or a fishing rod.

BEST MODE

[0021] A hula-hoop 100 to which the technique of the present invention is applied includes: a main body 101 divided into a plurality of parts having a circular sectional shape and having a circular arc shape when viewed from a plan view; a plurality of middle bodies 102, 103, and the like received in and withdrawn from one side of the main body 101; and an end body 104 coupled to a last middle body 103 among the middle bodies 102, 103, and the like so as to be received in and withdrawn from the last middle body 103 and connected to another side of the main body 101.

[0022] The number of divisions of the hula-hoop 101 is at least three, preferably four to six, and more than six may not matter. However, when the number of divisions of the hula-hoop 101 is unnecessarily large, it is not preferable because there may be difficulty in manufacturing as well as disassembly and assembly.

[0023] The main body 101, the middle bodies 102, 103, and the like, and the end body 104 may be preferably coupled to each other such that the main body 101, the middle bodies 102, 103, and the like, and the end body 104 are received and withdrawn in multi-steps in the form of an antenna or a fishing rod, wherein a diameter of the main body 101 is the largest, and diameters of the middle bodies 102, 103, and the like and the end body 104 sequentially become smaller.

[0024] Naturally, a front inner diameter side of the main body 101 may be slightly smaller than a rear outer diameter side of the middle body 102, a front inner diameter side of the middle body 102 may be slightly smaller than a rear outer diameter side of the next middle body 103, and a front inner diameter side of the middle body 103 may be slightly smaller than a rear outer diameter side of the end body 104, so that stopping may be possible due to a diameter difference upon the withdrawal.

[0025] As another example, each of the front inner diameter side of the main body 101, the front inner diameter sides of the middle bodies 102,103, and the like and the rear outer diameter side of the end body 104 may be provided with a latching sill that may be engaged, so that the stopping may be possible upon the withdrawal.

[0026] In addition, the inner diameter side of the main body 101 may be provided with a partition wall 105 to prevent the received middle bodies 102, 103, and the like and the received end body 104 from being separated from the main body 101, and a connection device may be provided on a front side of the end body 104 and the other side of the main body 101 to maintain the withdrawn middle bodies 102, 103, and the like and the withdrawn end body 104 in a circular shape.

[0027] The connection device 106 includes a male body 107 formed on the side of the end body 104 and a female body 108 formed on the other side of the main body 101 so as to be coupled to the male body 107.

[0028] The male body 107 includes an elastic body 109, such as a spring, provided within a front inner diameter of the end body 104, and a protrusion 110 of the elastic body 109 is exposed through an elastic body hole 111 formed in the end body 104.

[0029] The female body 108 includes an end body hole 112 formed on the other side of the main body 101 to receive a front outer diameter of the end body 104, and a protrusion groove 113 formed on an inner side of the end body hole 112 to receive the protrusion 110 of the elastic body 109.

[0030] The protrusion 110 and the protrusion groove 113 may be forcibly disassembled by pulling. As another example, a release button 114 may be further provided on the main body 101 to facilitate the separation.

[0031] It may be preferable that the main body 101, the middle bodies 102, 103, and the like, and the end body 104 are provided with a concave groove 115 and a protrusion 116 in a longitudinal direction, which are engaged with each other to maintain predetermined orientation at all times during the reception and the withdrawal, so that the hula-hoop may maintain a normal circular shape upon completion of the hula-hoop.

[0032] In addition, the hula-hoop may be further provided with a separate closing cap to prevent foreign substances and the like from being introduced into a front side of the end body 104 received in the main body 101 and the end body hole 112 formed on the other side of the main body.

Mode For Invention

[0033] When the hula-hoop 100 is not in use, the middle bodies 102, 103, and the like and the end body 104 are received in the main body 101 so as to make the volume corresponding to a size of the main body 101 and store or move the hula-hoop 100, and since the volume is small, it is possible to provide portability and ease of mobility as well as ease of storage.

[0034] When the hula-hoop 100 is to be used, the middle bodies 102, 103, and the like, and the end body 104 received in the main body 101 may be withdrawn and coupled in a circular shape so as to be used, wherein the middle bodies 102, 103, and the like are sequentially withdrawn when the front side of the end body 104 is gripped and pulled.

[0035] Naturally, when an entirety of the main body 101, the middle bodies 102, 103, and the like, and the end body 104 is withdrawn, the main body 101, the middle bodies 102, 103, and the like, and the end body 104 form a circular ring shape. In addition, when the connection devices 106 provided on the front side of the end body 104 and the other side of the main body 101 are coupled to each other, a circular connection state may be continuously maintained, so that exercise and play using the hula-hoop may not be interfered.

[0036] In particular, since the main body 101, the middle bodies 102, 103, and the like, and the end body 104 are provided with the concave groove 115 and the protrusion 116 to prevent orientation from being distorted upon the withdrawal and the reception, so that predetermined orientation may be maintained at all times during the reception and the withdrawal, which facilitates the completion of the hula-hoop and the reduction of the volume.

[0037] Upon the reception, when the end body 104 and the middle bodies 102, 103, and the like may be pushed into the main body 101, rear ends of the middle bodies 102, 103, and the like and the end body 104 may make close contact with the partition wall 105 provided on the main body 101, so that any further reception may stop. Upon the withdrawal, the withdrawn state may be maintained such that a rear side of the end body 104 is latched to front sides of the middle bodies 102, 103, and the like, and rear sides of the middle bodies 102, 103, and the like are latched to a front side of the main body 101.

INDUSTRIAL APPLICABILITY

[0038] The present invention as described above has advantages that the hula-hoop is received when the hula-hoop is not in use to provide portability and ease of storage and mobility, and the hula-hoop is withdrawn and connected in a circular shape when the hula-hoop is in use to utilize the hula-hoop for exercise and play.
