Description

Self-generating light skipping rope {SELF GENERATING TYPE LIGHT EMITTING JUMP ROPE}

The present invention relates to a self-generating light-emitting rope skipping rope, and more specifically, a part of the rope skipping rope is made into a rotating case, and a rotor coil is mounted in the rotating case. Electricity is generated from the rotor coil, and this electric power is supplied to a plurality of LEDs embedded in the rope skipping line to emit light, thereby improving nighttime movement and preventing injuries of people around it, while also maintaining a separate battery such as a battery. The present invention relates to a self-generating light emitting rope that can reduce the weight of the handle because it can emit light without having a power source.

In general, rope skipping is widely known to the general public as part of a series of health exercises and beauty exercises, and various kinds of movements are possible, such as being done by yourself on a short line and by several people on a long line. Rope skipping continuously for a long time because it stimulates the respiratory circulation and muscles is effective to increase the endurance of the whole body. In addition, there are various kinds of jumping motions as described above, which is effective in developing a general sense of rhythm and timing. It is a general exercise and does not require a large place, so it is widely used as a training tool for sports.

Commonly used rope skipping consists of a rope made of synthetic resin and a handle installed at both ends of the rope. In this way, the rope skipping rope is made of a flexible synthetic resin can be secured to some extent, but in the case of rope skipping in the dark night to identify the trajectory of the rope in the process of rotating around the athlete at a relatively high speed Is difficult. As a result, it becomes difficult to determine the position of the string, so that a footing phenomenon occurs frequently, thereby reducing the effectiveness of the exercise. In addition, pedestrians walking around or passing around athletes, especially children who lack the ability to identify the rope skipping rope, so there is a risk of trauma to the rope skipping.

As one of efforts to solve this problem, Korean Utility Model Publication No. 1991-8308, registered on October 15, 1991, discloses a luminous jump rope made of luminous material or phosphorescent material. This nocturnal rope skipping rope forms a mandrel of a rope skipping rope with a photoluminescent material, and the transparent coating layer surrounding this mandrel has the structure which embedded many reflective papers. However, the luminous rope skipping of this configuration has not been commercially successful due to the disadvantage that the price of the product is increased due to the use of expensive photoluminescent material and the luminous intensity is inferior.

On the other hand, Korean Utility Model Registration No. 199873, registered on August 4, 2000, discloses a shiatsu jump rope having a transparent hose string which flashes in multiple colors. In the structure of the acupressure rope jumper, the handle is composed of a guard unit formed with a number of acupressure protrusions on the outer periphery, an on / off switch for inserting and removing a battery on one side, and a battery insertion unit and a light emitting diode (LED) on the inside. The oscillating circuit for driving) is embedded and the string connected to the handle has a structure formed of a transparent synthetic resin hose in which a plurality of light emitting diodes are embedded.

Similarly, Korean Utility Model Registration No. 217256, registered January 8, 2001, discloses a similar jump rope. The lighting rope skipping is a handle having a wire having a plurality of colored light bulbs embedded in the inside of the transparent synthetic resin tube, a handle for inserting and fixing both ends of the line having a plurality of electric wires having the transparent synthetic resin tube, and the one side handle A grounding terminal consisting of a coil spring and a grounding ring inside the battery, a battery accommodating part for supplying power by embedding a battery in the inside of the other handle, and one side of the wire located inside the transparent synthetic resin tube The stage is grounded to the power switch unit installed in the handle, and the other end of the wire is connected to the + and-ground terminals of the battery compartment installed in the handle. Has a structure.

In the case of jumping rope disclosed in the utility model registration is equipped with a light emitting means has the advantage of increasing the ability to identify at night to increase the exercise effect and prevent the injuries of people around, but the hassle of having to replace the battery that plays the role of power every time In addition, the handle portion is heavy due to the weight of the battery, which causes fatigue easily during long exercise.

The present invention for solving the above problems by installing a plurality of LEDs in the rope skipping rope, by generating electricity according to the rotation of the rope skipping to provide electricity to the LED inside the handle, the whole rope skipping The purpose of the present invention is to provide a self-developed light skipping rope that can reduce the weight of the battery and reduce the cost of battery replacement.

In addition, two support jaws 227 are formed inside the lower retainer 202 to seat the flange of the rope skipping rope. A circular bulkhead 224 formed with a jaw is formed in the shaft center of the lower rotary case 220, and a through hole 228 is formed in the circular bulkhead 224. Here, the circular partition wall 224 is formed integrally with a plurality of linear partition walls 223 for supporting the rotor coil. In particular, the lower retainer portion 202 is formed with two rails 221 and 222 slightly protruding in circular ring shapes having different diameters, so that the contact and at the time of rotation with the pedestal 120 will be described later. Minimize frictional resistance.

As shown in FIGS. 6A to 6C, the pedestal 120 forms a hollow protrusion 128 inserted into the through hole 228 of the lower rotating case 220 at the shaft center, and the protrusion 128 is formed. A circumferential wall is formed at a position away from the predetermined distance, that is, a position where the lower portion of the lower rotating case 220 can be wrapped. In addition, three plate bolt holes 121 are formed on the lower surface, and the pedestal 120 is screwed tightly to the upper surface of the handle bar 110.
