In this way, the occupational groups that use the wrists are exposed to diseases such as the wrist tunnel syndrome which is caused by the fatigue of the wrists. Therefore, the muscles of the fingers, the palms and the wrists are partially rigid and fatigued, and the blood circulation is not smooth due to the lack of oxygen supply to the brain, resulting in heavy headache and sickness, systemic fatigue, it's difficult.

In order to solve the rigid muscles of the hands and arms, a wrist motion machine was conventionally used. As a conventional wrist motion mechanism, a knob is formed at both ends of a coil spring to grip the handle and move the spring together. A method of pulling one end of the spring on the toes and pulling by hand is disclosed in Korean Utility Model Publication No. 94-2774 (Japanese Utility Model Publication No. Hei 3-27261), and various other kinds of things, but they are mainly used in one direction And the muscles of the arm were strengthened by reciprocating motion with a certain stroke distance.

Thus, since the conventional wrist exerciser is only able to perform individual exercises, it is inconvenient to provide the wrist exerciser for various exercises.

Also, since one wrist motion machine provides only a certain tension or elastic force, there is a problem that the user can not select the exercise with various strengths depending on his or her own exercise capacity and condition.

The present invention has been made to solve the above problems of the prior art, and the present invention is intended to allow a user to perform various exercises through a single wrist exercise machine.

The present invention relates to a wrist exercise device, which enables various exercises using a single wrist exercise device. The wrist motion device according to the present invention can be variously modified, such as bending, rotating, and stretching, so that the user can perform his or her desired type of motion using a single wrist motion mechanism.

A first embodiment of the wrist motion mechanism according to the present invention is shown in Figs. 1 and 2. Fig. As shown in the figure, the wrist motion mechanism according to the present invention is largely composed of the elastic body 10, the first handle 20 and the second handle 30. They are assembled together to form one wrist motion mechanism. 1, these components are shown assembled together and are shown separately in Fig.

The elastic body 10 is composed of a coil-shaped spring. The elastic body 10 is a part that provides an elastic force in the wrist motion mechanism, and is made of a material having elasticity. In this embodiment, the elastic body 10 is a coil-shaped spring. As shown in FIG. 1, the elastic body 10 is a cylindrical shape extending in one direction, but it is not necessarily limited thereto, and may be a structure having a polygonal cross-section.

A first screw thread 11 is formed on the outer surface of the elastic body 10. The first thread 11 is for joining the elastic body 10 with the first handle 20 and the second handle 30 and may be integrally formed along the longitudinal direction of the elastic body 10, As shown in FIG. In the embodiment shown in Figs. 1 and 2, the first thread 11 is formed over the entirety of the elastic body 10. [

In this embodiment, the first screw thread 11 is formed of a male screw thread, which is not formed through a separate process, but may be formed naturally on the outer surface of a coil-shaped spring. That is, it can be seen that the elastic body 10 is formed by winding the metal wire in the form of a coil, so that the first thread 11 is formed on the outer surface thereof.

The first handle 20 and the second handle 30 are coupled to both ends of the elastic body 10, respectively. The first handle 20 and the second handle 30 are portions to be held by the user and have a three-dimensional shape protruding from the elastic body 10. In this embodiment, the first handle 20 and the second handle 30 have the same shape, more precisely spherical. Here, the spherical shape may be a shape in which a plurality of planes are connected or a plurality of dimples are formed instead of a curved surface, together with a complete spherical surface whose outer surface is composed of curved surfaces. The first handle 20 and the second handle 30 have a spherical shape so that the user can freely grip the first handle 20 and the second handle 30 in various directions, You can exercise. Although not shown, the outer surface of the first handle 20 and the second handle 30 may further include an acupressure projection.

Second threads 23 and 33 are formed on the inner surfaces of the first handle 20 and the second handle 30. The second threads 23 and 33 correspond to the first threads 11 of the turnable body and are formed in the assembly holes 22 and 32 formed in the first handle 20 and the second handle 30, do. Since the first handle 20 and the second handle 30 have the same structure, the first handle 20 will be referred to as a first handle 20, 22, and a second screw thread 23 is formed on the inner circumferential surface thereof. The second thread 23 is a female thread and corresponds to the first thread 11. Accordingly, when the first handle 20 is rotated, the first handle 20 is engaged with the elastic body 10. [ This is shown in FIG.

The first handle 20 and the second handle 30 are screwed to the elastic body 10 so that the first handle 20 and the second handle 30 are screwed to the elastic body 10, The distance between the first handle 20 and the second handle 30 can be changed according to the degree of the contact. 3 (a), the first handle 20 and the second handle 30 are shown as being spaced farthest from each other. In FIG. 4 (a), the first handle 20 and the second handle 30 Are shown in a state close to each other. As described above, when the distance between the first handle 20 and the second handle 30 is changed, the elastic force by the elastic body 10 becomes different. The user can adjust the distance between the first handle 20 and the second handle 30 to set an appropriate elastic force to the user.

Of course, the elastic body 10 itself may be replaced. For example, after the first handle 20 and the second handle 30 are separated from the elastic body 10, the elastic body 10 having different thicknesses and lengths can be replaced. Thus, the elastic force of the wrist motion mechanism can be varied and used.

Fig. 3 (b) and Fig. 4 (b) show a state in which the wrist motion mechanism according to the present invention is bent. Fig. 3 (b) shows a state in which a relatively small elastic force is applied as compared with Fig. 4 (b). As such, different elastic forces may be provided to the user depending on the distance between the first handle 20 and the second handle 30.

Figs. 5 to 10 show a method of performing the wrist motion using the wrist motion mechanism according to the present invention.

First, as shown in FIG. 5, as shown in FIG. 5 (a), the user begins to exercise while holding the wrist motion mechanism with both hands. More precisely, when the elastic body 10 is bent while the first handle 20 and the second handle 30 are gripped while the hand of the user is parallel to the elastic body 10 while overcoming the elastic force of the elastic body 10, The first handle 20 and the second handle 30 are bent in a direction in which they approach each other. This state is shown in Figs. 5 (b) and 5 (c). By this operation, the left and right bending motion of the wrist can be performed.

Next, referring to FIG. 6, as shown in FIG. 6 (a), the user starts the exercise while holding the wrist motion mechanism with both hands. More precisely, the elastic body 10, while overcoming the elastic force of the elastic body 10 in a state in which the first and second knobs 20 and 30 are grasped with both palms of the user facing each other, The first handle 20 and the second handle 30 are bent in a direction in which the first handle 20 and the second handle 30 are brought close to each other. This is shown in Figs. 6 (b) and 6 (c). This action allows the wrist to bend back and forth.

Referring to the exercise method shown in FIG. 7, as shown in FIG. 7 (a), the user starts exercising while holding the wrist exercise device with both hands. More precisely, the elastic body 10 is bent while the first handle 20 and the second handle 30 are held so that the user's hand is parallel to each other, thereby overcoming the elastic force of the elastic body 10, 20 and the second handle 30 are bent toward each other. The difference from the exercise method shown in FIG. 5 is the direction of waving the wrist, which is the same as that shown in FIG. 5, but the direction in which the wrist is rotated is orthogonal. Such a state is shown in Figs. 7 (b) and 7 (c). Through this operation, the user can rotate the wrist.

8, the user starts the movement while gripping the wrist motion mechanism with both hands. When the elastic body 10 is held in the state that the first knob 20 and the second knob 30 are gripped, So that the elastic body 10 is stretched while the elastic force of the elastic body 10 is overcome. Fig. 8 (a) shows a state in which the elastic body 10 is reduced, and Fig. 8 (b) shows an elongated state. These movements allow the user to perform upper body movements, including arms, as well as wrist movements.

9, the user starts the movement while holding the wrist motion mechanism with both hands. When the user pushes the first and second knobs 20 and 30 so as to be parallel to each other, So that the elastic body 10 can be bit-moved while overcoming the elastic force of the elastic body 10 in a gripped state. More precisely, the hand holding the first handle 20 and the hand holding the second handle 30 are rotated in directions opposite to each other, so that the elastic body 10 is twisted. That is, by rotating both ends of the elastic body 10 in opposite directions with a virtual line extending along the longitudinal direction of the elastic body 10 as a rotation axis, the wrist can be rotated.

10, the user starts the exercise while holding the wrist motion mechanism with both hands. The user moves the first knob 20 and the second knob 20 such that both palms of the user are facing each other, The beveled movement of the elastic body 10 is performed while overcoming the elastic force of the elastic body 10 while the handle 30 is grasped. More precisely, the hand holding the first handle 20 and the hand holding the second handle 30 are rotated in directions opposite to each other, so that the elastic body 10 is twisted. That is, by rotating both ends of the elastic body 10 in opposite directions with a virtual line extending along the longitudinal direction of the elastic body 10 as a rotation axis, the wrist can be rotated. The difference from the exercise method shown in FIG. 9 is that the direction of the gripped hands is orthogonal, and the exercise effect can be obtained at other parts of the wrist while rotating the wrists in different directions.

On the other hand, Fig. 11 shows a second embodiment of the present invention. In this embodiment, the first handle 20 is provided with a fixing protrusion 25 and the second handle 30 is provided with a fixing groove 25 corresponding to the fixing protrusion 25 35 may be formed and coupled to each other. 11B shows a state in which the fixing protrusion 25 is inserted into the fixing groove 35 so that the first and second knobs 20 and 30 are engaged with each other.

When the first and second knobs 20 and 30 are coupled to each other through the fixing protrusion 25 and the fixing groove 35, the entire length of the wrist motion mechanism is shortened, It can also be held on the protruding part. In addition, when the user grips the wrist motion mechanism with one hand and applies a force in the direction of arrow P in FIG. 11 (b), it can be utilized as a kind of a force. Since the portion of the elastic body 10 that the user applies the force to be squeezed is restored to a circular shape by the elastic force, the rat can be used as a gripping force while repeating the operation.

On the other hand, Fig. 12 shows a third embodiment of the present invention. The elastic body 10 may further include a first auxiliary handle 20 'and a second auxiliary handle 30' on the outer sides of the first handle 20 and the second handle 30, respectively, . Here, the first auxiliary handle 20 'and the second auxiliary handle 30' may also be screwed to the elastic body 10.

Since the auxiliary handle is fixed at a different position from the first handle 20 and the second handle 30, the user can select the portion to be gripped. For example, when the user holds the first handle 20 and the second handle 30 and flexes the elastic body 10, the first inner auxiliary handle 20 'and the second auxiliary handle 30' It is possible to recognize that the elastic body 10 has been sufficiently rotated by the user.

Fig. 13 shows an exploded view of the fourth embodiment of the present invention. As can be seen, the elastic bodies 10 and 100 may be formed of two pieces. That is, the elastic bodies 10 and 100 include a first body 10 formed of a coil-shaped spring and having a storage hole H formed along the longitudinal direction thereof, and a second body 10 inserted into the storage hole of the first body 10 And a second body (100) made of a material that is elastically deformable to increase the elastic force of the elastic body (10, 100). Since the first body 10 and the second body 100 are overlapped, the total elastic force can be increased, and the user can obtain a greater exercise effect. Here, the second body 100 may be a coil-like spring like the first body 10, or may be made of various elastically deformable materials such as rubber, plastic, and silicone.
