The present invention relates to an exercise equipment for wrist training, and more particularly, to constitute a light emitting body and a light emitting means, and the light emitted from the light emitting body with the rotation of the rotating body is amplified a sense of interest according to the interest can be used for a long time, The present invention relates to a wrist exercise equipment to increase the exercise effect.

In general, athletes such as baseball or tennis, or general clerks and students who use wrists frequently snap the wrists frequently to relieve wrist fatigue, but there is no sense of pleasure, so it is simple for only a short time. There was a problem that can not eliminate the fatigue of the wrist.

Looking at the domestic Utility Model Publication No. 1996-0006643 proposed to solve the above problems, Figure 1 is an exploded perspective view of a conventional exercise equipment for wrist, Figure 2 is a cross-sectional view according to Figure 1, exercise equipment for wrist training (A) is injection molding a generally semi-spherical lower case (4) formed therein the operating hole (2) with a synthetic resin, but the fixing frame (6) is formed in the center of the upper edge of the lower case (4) Locking jaw (8) 10 is formed in the upper and lower rear, the outer surface is rotated in the fixing groove 16 of the lower case (4) of the circular support ring 14 is formed with a hook frame 12 of a certain thickness It is installed so as to be fitted, but the coupling holes 18 and 20 are formed to face the left and right central portions of the support ring 14.

In addition, the support shaft 22 made of metal is formed in the inner center, and the synthetic resin is integrally molded so that a cylindrical weight 24 made of a cylindrical shape is formed outside the central portion of the support shaft 22 to form a circular rotary ball. (26) is molded and formed in the outer center portion of the concave groove 28 along the rotational direction of the rotation hole 26, and the one side of the concave groove (28) to form a locking piece (30) and then the rotary ball The connecting rods 32 and 34 formed on both sides of the support shaft 22 of the 26 are rotatably coupled to the left and right coupling holes 18 and 20 of the support ring 14.

And the operating hole 36 is formed therein, and the upper case 40 is formed by injection molding the upper case 40 with a transparent synthetic resin so that the opening hole 38 is formed in the upper surface of the fixing frame of the upper case 4 in the fixing groove formed at the bottom edge. After the 6 is fitted to be fitted, the upper and lower edges of the lower case 40 and 4 are adhesively fixed with a strong adhesive, and the upper part of the rotary hole 26 is formed to protrude outward through the opening 38. The upper part of the engaging frame 12 of the support ring 14 installed in the lower fixing groove 16 is wrapped around the support jaw 42 of the upper case 40 so that the detachment of the support ring 14 is prevented.

Looking at the operation state of the exercise equipment for wrist training (A), the hook of the operation string of a predetermined length to the engaging stone piece 30 formed in the recessed groove 28 of the rotary hole 26 through the upper opening hole 38 Insert the 46 and rotate the rotary ball 26 in the opposite direction to wind the operation strap 44 in the indentation groove 28, and then wrap the bottom of the wrist training exercise (A) with one hand and with the other hand Holding the handle of the operation strap and pulling in one direction forcibly, while the rotary ball 26 is rotated vertically, the support ring 14 fitted with the rotary ball 26 is also fixed to the upper and lower cases 40 and 4. In the groove 16 is rotated horizontally, but if the wrist is rotated according to the sense of rotation of the rotary sphere 26 before the rotational force of the rotary sphere 26 is weakened, the support ring 14 rotates horizontally and at the same time the rotary sphere (26) is rotated and the rotational force of the rotary hole 26 allows a high-speed rotation up to about 8,000 times per minute.

In addition, when the protrusions 114 and 124 correspond to each other, a space portion is formed between the vertical cross-sections 112 and 122, and the space portion performs the same function as the rim groove 102 of the rotating body 100. In addition, any one side of the protrusions 114 and 124 is formed with a locking groove 104 is bisected each.

In particular, the first body and the second rotating unit 110, 120, the weight body 118, 128 is configured, the weight body is fitted to the first and second rotating unit 110, 120, As shown, it can be integrally formed by insert injection, in which case the weights 118 and 128 are preferably configured to have a greater weight on either side of the first and second rotating parts 110 and 120. Do.

On the other hand, the first and second rotating parts 110 and 120 are combined by gluing or fusion by an adhesive, or can be combined by various methods such as fastening by fastening and screwing by a fitting method. It is thought.

When the rotating body according to the second embodiment configured as described above is rotated at high speed through the operation strap and the snap of the wrist, the rotational force is increased as the moment of inertia is amplified by the load biased to either one of the first and second rotating parts. Doubled, this makes it easy for even novice users to easily amplify the rotational force of the rotating body (100).

9 is a partially exploded perspective view of the snap ring according to the third embodiment, FIG. 10 is a partially enlarged cross-sectional view of the snap ring of the third embodiment, and FIG. 11 is a partially enlarged side cross-sectional view of the coupling state of the snap ring, and like reference numerals denote the same elements. The detailed description thereof is omitted.

Wrist training apparatus according to the third embodiment is composed of a rotating body 100, the light emitting body 200, the snap ring 300, the first and second cases 410, 420, and the light emitting means 500 The snap ring 300 includes an elastic member 600, and a snap ring inserted into the guide grooves 414 and 424 of the first and second cases 410 and 420 by the elastic member 600. 300) to be kept spaced apart at regular intervals.

In addition, the elastic member 600 is composed of a ball 610 and a spring 620, which is configured so that the ball 610 is provided with an elastic force by the elastic force of the spring 620, the ball 610 The silver is preferably configured to protrude a portion on the side of the snap ring (300).

In addition, in order to configure the elastic member 600 in the snap ring 300, the snap ring 300 has a seat hole 302 penetrating downward from the upper surface and a portion of the seat hole 302 in the outer peripheral side on a straight line A plurality of through holes 304 are formed.

Therefore, after the ball 610 is inserted through the seat hole 302, a part of the ball 610 protrudes to the outside through the through hole 304, and a spring 620 to the rear of the ball 610. This is made up.
