Description

Luminescent Hula Hoop {Hula-hoop with a illuminator}

The present invention relates to a light emitting hula hoop.

In general, hula hoops are widely used not only as children's play equipment but also as an exercise means for developing body flexibility.

However, the conventional hula hoop can only perform a simple exercise function that rotates while moving the body, so that users are easily tired, and the use of the hula hoop has also been a major cause of decrease.

In order to solve this problem, Korean Utility Model Publication Nos. 95-5712 and 97-6742 disclose light emitting hula hoops to increase the user's interest and reduce the desire for use by adding a light emitting function. These light emitting hula hoops are connected to a plurality of light emitting elements at a predetermined interval in the hula hoop main body by a conductive member for power supply, and emit light by physical contact or the like when using the hula hoop.

However, in the conventional light emitting hula hoop, the light emitting element emits light periodically by pressing the switch on the outer surface of the light emitting hula hoop by physical contact or the like by periodically emitting light by the time setting of the microcomputer. Accordingly, the light emitting hula hoop users have a problem that interest and hobby are reduced by simple periodic light emission of the light emitting device.

Accordingly, it is an object of the present invention to provide a light emitting hula hoop which causes a continuous interest and hobby by causing the light emitting element to emit aperiodic light when using the hula hoop.

The object is a light emitting hula hoop having a tubular hula hoop body forming a circular ring, a battery installed in the hula hoop body, and at least one light emitting element disposed in the hula hoop body to emit light by a power supplied from the battery. A cylindrical movable contact electrically connected to any one of the battery and the light emitting device, and coupled to the other of the battery and the light emitting device and coaxially installed with the fixed contact, can cause fluctuation of the hula hoop body. It is achieved by a light emitting hula hoop comprising a spring elastically contacting and spaced apart from the fixed contact and flashing the light emitting device.

Here, the fixed contact is preferably a cylindrical conductor. The spring is a coil spring installed coaxially with the fixed contact, and the coil spring is accommodated in the fixed contact or spirally surrounds the fixed contact from the outside. It is effective in forming a multi-contact surface to make the light emitting device blink.

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

1 is a perspective view of a light emitting hula hoop according to the present invention, Figure 2 is a partially enlarged perspective view of FIG. As shown in these figures, the light-emitting hula hoop includes a tubular hula hoop main body 10 forming a circular ring, a power supply unit 30 provided in the hula hoop main body 10, and disposed in the hula hoop main body 10 to supply power. It includes a light emitting device 20 for emitting light by the power supplied from the supply unit 30.

The hula hoop main body 10 may be formed by a combination of tubular bodies forming a circular ring, and in the embodiment of the present invention, a not shown locking jaw is formed in the power supply unit 30 in a predetermined region along the circumferential direction. And by the engaging piece is elastically coupled and separated through the engaging and releasing process.

As shown in FIG. 1, the power supply unit 30 includes a battery 33, a battery accommodating part 31 coupled to the hula hoop main body 10 to accommodate the battery 33, and a positive electrode of the battery 33. It includes a conductive wire 35 connected to. At both ends of the battery accommodating part 31, a ground piece 37 is formed to elastically contact the battery 33, and a conductive wire 35 is connected to each ground piece 37.

A plurality of light emitting elements 20 are arranged at regular intervals in the hula hoop body 10, and each light emitting element 20 is electrically connected to each other by the conductive wires 35 arranged thereon.

On the other hand, the vibration flashing switch 50 is provided between the power supply unit 30 and the light emitting device 20 to intercept the power supplied from the power supply unit 30. The vibration flickering switch 50 is provided at one side of the fixed terminal 40 provided on one side of the conductive wire 35 connected to the ground piece 37 and the conductive wire 35 connected to the light emitting element 30. And a movable contact which is in contact with and spaced apart to flash the light emitting device 20.

The fixed terminal 40 includes a fixed contact 41 for accommodating a movable contact therein in a cylindrical shape, an insulating base 45 for supporting a fixed contact 41 and a movable contact in a disc shape, and a fixed contact 41. It includes a ground portion 43 protruding in one lower region to electrically connect the fixed contact 41 and the power supply 33.

The movable contact is a coil spring 47 that is an elastically restorable spring, which is contacted and spaced apart from the fixed contact 41 when the hula hoop main body 10 swings. Accordingly, the light source of the hula hoop main body 10 is interrupted. ) Flashes. The coil spring 47 is formed coaxially with a cylindrical fixed contact 41 having a contact surface as shown in FIG. When the hula hoop main body 10 swings, the coil spring 47 moves left and right to contact and spaced apart from the fixed contact 41. Accordingly, power from the battery 33 is supplied to the light emitting device 20 to emit light. 20) flashes aperiodically.

In the present embodiment, the fixed contact 41 is a cylindrical fixed contact 41 having a contact surface, but it can be formed into a fixed contact of various shapes such as polygonal shape in order to maintain contact and separation with the coil spring 47. Of course, the coil spring 47 is accommodated in the fixed contact 41, but the coil spring 47 is formed to surround the fixed contact 41 from the outside to supply power from the battery 33 to the light emitting device. 20 can be supplied.

According to such a configuration, when the user rotates the light emitting hula hoop, the coil spring 47 accommodated in the fixed contact 41 connected to the conductive wire 35 of the battery 33 moves left and right by shaking, and the fixed contact 41 is moved. In contact with and spaced apart. As a result, power is aperiodically supplied from the anode and the cathode of the battery 33 to the light emitting device 20 so that the light emitting device 20 flashes aperiodically.

As such, the light emitted from the light emitting device is aperiodicly flickered by the fixed contact point and the movable contact point provided in the hula hoop body, and the flashing light also does not give the user a sense of interest because the brightness is not constant. It can make the most of the function of the luminescent hula hoop that is continuously induced.

As described above, according to the present invention, the light emitting device flashes aperiodically by the fixed contact point and the movable contact point when the hula hoop is used, thereby providing a light emitting hula hoop that causes a continuous interest and a hobby to the users.
