The third accelerometer 70 is coupled to the third coupling groove 43 of the third connector and has a closed end of the third pipe 71 and a conductor that is movably embedded in the third pipe 71. And a third weight 72 made of material. A third cap 73 provided at the inlet side of the third pipe 71, a third flat terminal 74 provided at the center of the third cap 73 inside the third pipe 71, and a third The third ring terminal 75 which is installed at the edge of the third cap 73 inside the tubular body 71 and the third ring terminal 75 and the third weight 72 is installed between the third weight terminal 72.

The first, second and third tubular bodies 51, 61 and 61 are fitted into the first, second and third coupling grooves 23, 33 and 42 in the radial direction R to be coupled to each other. The two, three weights 52, 53 and 54 can be moved to the acceleration change applied only in the radial direction R.

The first, second and third caps 53, 63 and 73 are the first, second and third weights 52, 62 and 72 and the first, second and third springs 56, 66 and 76. The first, second and third weights 51, 62 and 71 are maintained in a state of being embedded, and at the front of the first, second and third weights 52, 62 and 72, The second and third flat terminals 54, 64 and 74 and the first, second and third ring terminals 55 and 65 and 75 are positioned.

The first, second and third connector terminals 57, 67 and 77 and the fourth, fifth and sixth connector terminals 58, 68 and 78 are the first, second and third protrusion terminals 25 described above. And electrically connected to (35) (45).

On the other hand, the first, second and third weights 52, 62 and 72 are first, second and third curved surfaces formed at positions corresponding to the first, second and third flat terminals 54, 64 and 74. The first, second and third springs 56, 66 and 76 are formed outside the portions 52a, 62a and 72a and the first, second and third curved portions 52a, 62a and 72a. The first, second, and third step fitting ends 52b, 62b, and 72b, so that the first, second, and third weights 52, 62, 72 are first, second, and third. The first, second and third flat terminals 54, 64 and 74 when the acceleration terminal changes in the radial direction R when the flat terminals 54, 64 and 74 are vertically supported. Can move

The first, second, and third weights 52, 62, and 72 moving by the change in acceleration are the first, second, third, and caps surrounding the first, second, and third tubular bodies 51, 61, and 71. By the (63) (73) can maintain an environment completely blocked from the outside, and thus can be completely waterproof to completely block the penetration of rain or moisture.

Due to this structure, as shown in FIG. 7, the first, second, and third weights 52, 62, 72 are divided into the first, second, and third springs 56, 66, 76, and the first, second, and third weights 52, 62, 72, respectively. The second and third flat terminals 54, 64 and 74 are physically separated from each other, and the first, second and third ring terminals 55 and 65 and 75 are electrically connected to each other.

However, when an acceleration change occurs in the radial direction R, the first, second, and third weights 52, 62, 72 apply the elastic force of the first, second, and third springs 56, 66, 76. It overcomes contact with the first, second and third flat terminals 54, 64 and 74, where the first, second and third flat terminals 54, 64 and 74 and the first, second and third ring terminals 55, 65, and 75 are electrically connected to generate the first, second, and third acceleration signals S1, S2, and S3.

In more detail, as shown in FIG. 9, when an acceleration change occurs in the radial direction R, that is, the hula hoop 100 contacts the user's body B and the center of the hula hoop C. FIG. When the hula hoop 100 is reversed to the opposite side (-R) of the radial direction R along the connecting virtual line, the hula hoop 100 remains in a state of not moving downward in the body B.

For example, as shown in FIG. 9, when the first acceleration sensor 50 is positioned on an imaginary line connecting the user body B and the center C of the hula hoop, the hula hoop 100 is moved by gravity. In order not to fall downward, the first acceleration sensor 50 must be moved in the radial direction (-R) opposite to the radial direction R on the side of the first acceleration sensor 50, so that the acceleration change in the first acceleration sensor 50 is changed. It happens. At this time, the first acceleration sensor 50 generates the first acceleration signal S1, and then the second and third acceleration sensors 60 and 70 sequentially rotate the second acceleration signal S2 and the third acceleration signal ( S3) is generated.

The counting unit 80 generates a corresponding count signal by counting 1 for each cycle condition in which the first, second, and third acceleration signals S1, S2, and S3 are sequentially generated. At this time. If the first, second and third acceleration sensors 50, 60 and 70 do not sequentially generate the first, second and third acceleration signals S1, S2 and S3, or only a specific acceleration signal is generated, the counting unit 80 does not count. This means that the user did not move with a hula hoop and only waved in a specific direction, in this case not counting. That is, the first, second, and third acceleration signals S1, S2, and S3 are sequentially generated only during the normal hula hoop movement, and only a specific acceleration signal is generated when the user shakes the hula hoop in an arbitrary direction. 1,2,3 acceleration signals are not generated sequentially.

On the other hand, the counting unit 80 includes a setting switch 85 for setting the count of the hula hoop to 0, and if necessary, the counting switch 80 can count the rotation of the hula hoop again by pressing the setting switch 85.

The voice output unit 90 outputs the number counted by the count unit 80 as voice, and includes a speaker (not shown). The voice output unit 90 outputs, for example, a voice of "one" when the counting unit 80 recognizes 1, and then outputs a voice such as "two" or "three". Accordingly, the user can accurately know the number of rotations without counting the number of hula hoops.

In the present exemplary embodiment, it is illustrated that only the voice output unit 90 in which voice is output by the count signal generated by the count unit 80 is employed, but a plurality of light emitting LEDs emitting light in association with the count signal are employed or counted. It is a matter of course that a display in which the number is displayed numerically may be employed.

Thus, according to the present invention, by employing the first, second and third connectors 20, 30 and 40, the pair of first, second and third connector protrusions 22, 32 and 42 are formed. By varying the length of the two tubes 10 can be varied in diameter, it is possible to implement a hula hoop suitable for a variety of body types.

In addition, the first, second and third acceleration sensors 50, 60 and 70 and the counting unit 80 may include the first, second and third acceleration signals S1 (generally generated when the user normally performs the hula hoop movement). Since the count proceeds in conjunction with S2) (S3), it is possible to prevent the manipulation of the count by shaking the hula hoop artificially without the hula hoop movement.

In particular, since the first, second, and third acceleration sensors 50, 60 and 70 measure acceleration changes, there is no protruding portion from the inner circumferential surface of the hula hoop 100, such as a switch, and thus waterproof is possible. Even when used outdoors, it can prevent the possibility of rainwater infiltration.

In addition, by outputting the count number as a voice, the user can accurately recognize the count number during the exercise, and induces curiosity and motivates exercise by the output voice.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
