{A WRIST TEMPER SPORTING GOODS}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wrist exercise opening, and more particularly, to a wrist exercise opening, in which a principle of action and reaction is applied to a central shaft for supporting a free rotation of the rotating body, The present invention relates to a wrist training opening for improving smoothness of use by smoothly and promptly rotating the rotary body by an initial start.

Generally, the general clerks and students who use the wrist mainly, that is, athletes such as baseball or tennis, or the keyboard, which is the input means of the computer, frequently give a snap to the wrist to relieve the fatigue of the wrist, There is a problem in that the simple fatigue of the wrist can not be solved due to the simplicity which is only for a short time without amusement feeling.

In order to solve the above-mentioned problems, an example of the proposed prior art is described in Korean Utility Model Publication No. 1996-6643 (published on August 3, 1996), which is a wrist training exercise, as shown in FIGS. 1 and 2 The lower case 4 is formed by injection molding a generally semi-spherical lower case 4 having an operation hole 2 formed therein. The fixing frame 6 is formed at the center of the upper edge of the upper case 4 of the lower case 4, And a circular supporting ring 14 having a hooking frame 12 of a predetermined thickness formed on the outer surface thereof is rotatably fitted in the fixing groove of the lower case 4, (18) and (20) are formed to face each other at the left and right central portions of the base plate (14).

A metal support shaft 22 is formed at the center of the inside and a synthetic resin is integrally formed on the outer side of the center of the support shaft 22 to form a cylindrical metal weight 24, And a locking protrusion 30 is formed at one side of the recess 28 so that the locking protrusion 30 is formed at the center of the outer circumference of the recess 26, The connecting rods 32 and 34 formed on both sides of the support shaft 22 of the support ring 26 are rotatably engaged with the left and right coupling holes 18 and 20 of the support ring 14,

The upper case 40 is injection-molded with a transparent synthetic resin so that an opening hole 38 is formed in the center of the upper surface of the upper case 40, The upper and lower cases 40 and 4 are bonded and fixed to each other with a strong adhesive so that the upper portion of the rotary tool 26 protrudes outward through the opening hole 38, The supporting jaw 42 of the upper case 40 covers the upper part of the holding frame 12 of the supporting ring 14 fitted in the lower fixing groove 16 to prevent the supporting ring 14 from being separated.

The operating state of the wrist training exercise area A is such that a loop of an operating strap having a predetermined length is formed on the stalk piece 30 formed in the concave groove 28 of the rotary tool 26 through the upper opening hole 38, The operator rotates the rotary tool 26 in the opposite direction by inserting the handle 46 into the groove 28 and winding the operation cord 44 around the insertion groove 28. The other end of the wrist- The support ring 14 in which the rotary tool 26 is vertically rotated and the rotary tool 26 is fitted is also fixed to the upper and lower cases 40 and 4 by being pulled in one direction by holding the handle of the operating strap, If the wrist is rotated in accordance with the sense of rotation of the rotary tool 26 before the rotary force of the rotary tool 26 is weakened and the wrist is rotated in the groove 16, The rotating shaft 26 is rotated and the rotating force of the rotating shaft 26 is normally rotated at about 8,000 times per minute.

When the first rotational force is applied to the rotating body provided in the case by the operating strap using the principle of the gyroscope, the rotating body rotates in the case by the added rotational force, In order to sustain or increase, it is a motion to strengthen the wrist fatigue and arm strength by giving a continuous snap to the wrist.

In another example, Korean Patent No. 694757 (name: wrist training exercise) of the present applicant has a frame groove having a certain depth on a vertical line, a latching groove is formed on one side of the frame groove, A rotating body having a supporting shaft protruding from both side ends of the rotating shaft; A light emitter provided in the rotating body; A snap ring provided inside the rotating body and supporting a support shaft protruded on both sides; A guide groove is formed on the inner horizontal line of the space so that the snap ring is inserted therein and an open end face is formed at an upper end of the guide groove so that a part of the edge groove of the rotary body is exposed to the outside, A first and second case formed and vertically split and joined; And light emitting means provided in the first and second cases, for providing a light source to a light emitting body provided in the rotating body.

However, there is a problem that it is difficult to start the rotating body at the initial stage of the wrist training using the principle of the conventional gyroscope.

That is, a rotational force having a constant velocity is initially required to rotate the rotating body, but it is not easy for children who have a smaller gripping force than a general adult, and thus the feeling of play is lost.

In addition, since the wrist training zone using the gyroscope principle was first developed by BOYD in the United States in 1987, it has been mass-produced without conversion of organization until the end of the prescription of patent rights, and the technical capability of the mass- .

As a result, the usability is complicated, the merchantability is undervalued, and the accessibility is getting worse.

≪ Embodiment 1 >

The wrist training exercise ball 100 according to the first embodiment of the present invention includes a main body 110 having a receiving space 112 formed therein and a rotating body 120 disposed in the receiving space 112 of the main body 110, A center shaft 130 formed at the center of the rotating body 120 and an operating strap 140 wound around the outer circumference of the rotating body 120 to cause an initial start.

The main body 110 is a means for grasping the user while protecting the components to accelerate the rotational force of the rotating body 120 with a snap of the wrist.

The main body 110 has an insertion groove 114 having a predetermined depth so that both ends of the central shaft 130 are inserted so that the rotating body 120 accommodated in the accommodation space 112 can rotate smoothly. As shown in Fig.

The rotating body 120 is initially rotated by pulling the operating strap 140 in a state where the operating strap 140 is wound around the outer circumference of the swing body 140. After the rotational force is accelerated by the snap of the wrist, .

The rotation body 120 is formed with a reduction groove 122 having a predetermined depth at the center so that the operation string 140 can be easily wound.

The actuating strap 140 is a means for rotating the outer circumference of the rotary body 120 through the reduction groove 122 and then performing an initial rotation on the rotary body 120 as it is pulled.

The center shaft 130 is formed at the center of the rotating body 120 and supports the rotating body 120 so as to be easily rotated so that the wrist motion can be smoothly performed It is means.

The center shaft 130 forms eccentricity so that the centrifugal force generated by rotating the rotating body 120 at the same time by rotating and revolving at the same time is applied to the rotating body 120 with the wrist force When the snap is applied, the rotating body 120 is accelerated by the centrifugal force, and the rotational force is increased. This action strengthens the wrist muscle strength.

Here, the action of the rotational force derived from both ends of the center shaft 130 acts on the eccentric center shaft 130 and the eccentric center shaft 130 acts on the eccentric center shaft 130. .

Accordingly, the rotating body 120 of the reaction force must be always given a reaction when snapping the wrist, so that it is always floated except for the moment of snapping in the accelerated state.

On the other hand, in the center shaft 130 having the eccentricity, as the rotational force increases as the acceleration increases, the centrifugal force is strongly generated and the rotational force is totalized, thereby maximizing the rotational efficiency.

That is, the center shaft 130 includes an eccentric portion 132 so that an eccentric force is exerted on one side.

The eccentric portion 132 of the center shaft 130 is formed at one side of the center shaft 130 as shown in FIG. However, the present invention is not limited thereto, and the eccentric portion 132 may be formed at the central portion.

One end of each of the opposite ends of the center shaft 130 forms a semispherical finishing portion 134. At this time, it is preferable that the hemispherical finishing portion 134 is formed at the end of one side where the eccentric portion 132 is located.

That is, one end of the center shaft 130 is formed with a hemispherical finishing portion 134, and the other end is formed with a straight finishing portion. By rotating the rotation body 120, When the shaft 130 rotates, the eccentric portion 132 causes the eccentric portion 132 to concentrate the rotational force on the hemispherical finishing portion 134 where the eccentric portion 132 is located.

≪ Embodiment 2 >

The same reference numerals are used for the same components as those in the first embodiment, and a detailed description thereof will be omitted.
