In addition, the pressing portion 210 is seated on the guide member 100 while being held in a more stable state by the combination of the guide member 100 formed in two rows and the pressing portions 210 rotating and generating upward and downward pressing force, . Therefore, the gravitational force machine 10 can more securely and securely maintain the close contact movement between the pressing portion 210 and the guide member 100. [

FIG. 7 and FIG. 8 are views showing a movement form of a gravitational force compensator according to an embodiment of the present invention, and FIGS. 9 and 10 are views showing another movement form of a gravitational force compensator according to an embodiment of the present invention.

7 to 10, the moving member 200 includes a first moving member 200a and a second moving member 200b. The plurality of pressing portions 210 constituting the moving member 200 have a structure in which they are rotated in contact with the guide member 100, respectively, and the two pressing rollers forming the respective contacting portions are integrally rotated. The guide member 100 has two sets of the first guide member 100a and the second guide member 100b which are mutually coupled to each other and are arranged in two rows.

The guide member 100 may have different shapes along the longitudinal direction. For example, the size of one end of the guide member 100 may be larger or smaller than the size of the other end. Therefore, the guide member 100 can maintain a tilted state with respect to the longitudinal center line. 7 and 8, the guide member 100 can be coupled with the second end portions 104, which are larger than the first end portions 102, correspondingly to each other. Conversely, as shown in FIGS. 9 and 10, the guide member 100 may be coupled to the first end portions 102 with the connection and fixing member 300 as a medium.

7, when the second end portions 104 of the guide member 100 are engaged with each other, the size (height) of the center portion is large along the length direction of the guide member 100, It will have a small size. Therefore, when the moving member 200 is moved to the center in the longitudinal direction of the guide member 100 during the force-based force exercise, the moving member 200 moves in a direction of climbing the inclined portion. Such movement resistance acts in a manner similar to the grip force of the user gripping the movable member 200, and functions to limit the movement of the movable member 200. Therefore, it is necessary to further increase the force necessary for the grip force exercise, so that the effect of the grip force exercise can be further obtained. That is to say, when the second end portions 104 of the guide member 100 are engaged with each other and the moving member 200 moves in the inclined direction toward the center portion of the guide member 100, So that the effect of collecting the chest becomes larger.

The user can move the first moving member 200a and the second moving member 200b toward the center of the guide member 100 in the initial state in which the first moving member 200a and the second moving member 200b are opened on both sides of the guide member 100, 200a and the second moving member 200b can be inclined upwardly. The first moving member 200a and the second moving member 200b are moved in the upward direction in a state of being in contact with the inclined portion 106 symmetrically symmetrical on both sides with respect to the longitudinal center of the guide member 100, . Therefore, since the first and second movable members 200a and 200b are symmetrically and symmetrically moved about the inclined portion 106, it is possible to prevent the left and right forces from being deviated from each other. That is, the left and right motion balances of the first moving member 200a and the second moving member 200b can be maintained more evenly. Therefore, it is necessary to separately practice the first moving member 200a and the second moving member 200b in order to maintain the left and right motion balances even if the user is not familiar with the force-applying force machine 10 according to the embodiment of the present invention And there is an effect that the left and right balance can be maintained in a more stable state and can be easily exercised. Actually, when the moving member 200 is mounted on a parallel-pipe-shaped guide rail, which is not an inclined guide member 100 according to the embodiment of the present invention, the same movement is performed. As a result, The left and right movement of the first moving member 200a and the second moving member 200b occurred in an unbalanced state. Therefore, there is a problem that it is difficult to maintain the left and right motion balances of the first moving member 200a and the second moving member 200b.

8, when the external force applied to the moving member 200 is removed in a state where the moving member 200 is moved in the longitudinal direction center of the guide member 100 as shown in FIG. 8, And moves in the downward direction of the inclined portion 106 of the main body 100. The restoring force of the first elastic part 226 and the second elastic part 228 constituting the pressing part 210 of the first movable member 200a and the second movable member 200b acts on the first movable member 200b, 200a and the second moving member 200b can more uniformly keep the moving motion of the guide member 100 down the slope portion 106. [ When the first moving member 200a and the second moving member 200b are moved in the direction of lowering the inclined portion 106 of the guide member 100, the first elastic portion 226 and the second elastic portion 228 As the restoring force acts, a large force is no longer necessary.

Referring to FIG. 8, a locking protrusion 104a is formed at the second end 104 of the first guide member 100a and the second guide member 100b. The locking protrusions 104a protrude upward from the second end portions 104 of the first guide member 100a and the second guide member 100b and the first moving member 200a and the second moving member 200b ).

On the other hand, as shown in FIGS. 9 and 10, the first end portions 102 of the guide member 100 may be engaged with each other to perform a gentle force exercise. In this case, the guide member 100 has a small center portion along the length direction and a larger size toward both ends. Therefore, when the moving member 200 is moved to both end portions of the guide member 100 in the case of the force-based force exercise, the moving member 200 moves in a direction of climbing the inclined portion. That is, when the first end portions 102 of the guide member 100 are engaged with each other, the effect of the exercising force of the chest (back motion) becomes greater when the force exercise is performed.

As described above, the structure in which the guide member 100 is formed to have a different size along the longitudinal direction and is inclined can be used not only when a plurality of guide members 100 are combined, but also in an integral structure.

11 is an assembled perspective view of a gravitational force compensator 10a according to another embodiment of the present invention. The grip force compensator 10a according to another embodiment of the present invention is formed in a pipe shape in which the guide member 1100 is not inclined, and most of the components except for some components are connected to the grip force compressor 10 according to the embodiment of the present invention. ≪ / RTI > However, since the guide member 1100 is horizontal, the pressing force and the restoring force are relatively weak as compared with the inclined shape. There is a somewhat different difference in that it further includes a tension member 1300 to compensate for this.

11, a gravitational force compensator according to another embodiment of the present invention includes a moving member 1200 and a tension member 1300 coupled to both ends of the guide member 1100 to provide a tension to the moving member 1200 . The tension member 1300 may be formed of an elastic band and may be formed of another member capable of connecting the guide member 1100 and the moving member 1200 to provide a tension when moving the moving member 1200 . For example, the tension member 1300 may use an elastic spring. The tension member 1300 can also be formed in such a manner that a wire or a cable is wound on and unwound from the spring.

In order to securely connect the tension member 1300, tension connection portions 1400 are coupled to both ends of the first guide member 1100a and the second guide member 1100b. The tension connecting portion 1400 has fixing holes 1420 on both sides. A separate fastening portion 1410 may be provided for fastening and coupling the tension connecting portion 1400 to both ends of the first guide member 1100a and the second guide member 1100b. The guide member 1100 may be provided with a stopper 1500 for restricting movement of the moving member 1200 in the longitudinal center portion thereof.

The force-type force compensator 10 according to the embodiment of the present invention is formed in an assembled shape and can be utilized not only as a basic type but also as a user-customized exercise machine. The conventional gripper is equipped with an elastic portion which directly generates a gripping force. However, in the embodiment of the present invention, there is a structural difference in that an elastic portion is provided at a portion separated from the grip portion 240 and indirect gripping force is generated. For this reason, the moving member 200 according to the embodiment of the present invention requires a gripping force to overcome the pressing force of the elastic portion. Therefore, the user can use the device as a single device, and the device can be applied to a sports device having a composite structure in which a hand gripper and a force holder are fused together as shown in FIG. Also, the grip force machine 10 can have a continuous movement effect of continuously variable transmission through the grip force and the force adjustment function. In other words, since the grip force modulator 10 can adjust the strength of the grip force and the force at the same time by only the user's force without manipulating the adjustment mechanism, it is possible to maintain the constant motion and omit the unnecessary intensity adjustment step while exercising, There is an effect that can concentrate.

In addition, since the handle 240 is formed on both sides of the first handle 240a and the second handle 240b, it is possible to perform a movement in a set of two. For example, a couple or lovers can move together while holding the first handle 240a and the second handle 240b of the movable member 200, respectively. In addition, users with different mobility can also be used as an auxiliary exercise equipment, so that both young and old can work together in pairs. It can also be used as a rehabilitation device for rehabilitation patients such as hospitals as well as exercise equipment.

As described above, the gravitational force compensator 10 is a multipurpose whole body exercise apparatus that appropriately adjusts the speed of the user's desired force to the force of the user, which is a force corresponding to the grip force of the user, and pumping the speed. In explaining the gravitational force compensator 10 according to the embodiment of the present invention, a description overlapping with the gravitational force compensator 10a according to another embodiment will be omitted. The grip force machine 10 can obtain various exercise effects by combining the grip force and the muscle force, and can constantly stimulate the necessary parts to maximize the exercise effect of the desired part. In addition, the grip force machine 10 can be configured to be portable, which is convenient to move, and can be assembled in various forms as needed, so that it is possible to obtain the effect of having various exercise apparatuses. Since the portable musical tone power unit 10 is constructed as a portable type and an assembled type, various types of exercises desired by the user can be performed because there is no burden of time, place, space noise and weight. The grip force gauge (10) is a multipurpose exercise apparatus that is useful not only for a user who performs a professional exercise but also for a user who is sitting on a chair for a long time or sitting on a chair, a student, or a user who is hard to exercise for various reasons. Also, the musical force weakener 10 can implement a desired movement effect by connecting a cable (or a wire) to a separate cradle, or to a separate barbell, a dumbbell, and a coupling part of a kettlebelt to apply various operations.

For example, the grip force machine 10 can implement the cable crossover chest movement, which is the most common in the gym. This exercise is good for men, but it is a better exercise for women. But at the gym, women can not help but be conscious of their surroundings to do cable cross-over chest exercises. Cable crossover The chest movement is so popular among users that it is hard to get enough to wait for the order. However, the grip force modulator 10 is advantageous in that it can enjoy various various operations including a cable crossover exercise while being portable anywhere without needing to notice.

On the other hand, the existing force balancer is formed to be substantially narrow due to the fact that the starting points of motions are fixed collectively or due to the shape restriction of the self-propelled machine itself. In contrast, according to the embodiment of the present invention, the user can adjust the starting point of the exercise to find a proper point and pump the strong motion more intensively. For example, since both arms are open and the chest muscles are gathered, a relatively large amount of exercise effect can be obtained in preparation for the same exercise time. Also, the gravitational force machine 10 has the merit of rolling the rotating part along the guide member 100 while applying a gripping force, rather than merely performing a lifting action, and pumping more pleasantly by adding complex fun to pull the cable as needed . In addition, the gravitational force compensator 10 is easy to move because its own weight is light, and has a merit that it can be pumped for a long time without any problem on the wrist of a user. Generally, conventional exercise equipment is not easy to carry around by users with 5kg ~ 15kg equipment, and there are a lot of wrists when pumping. Thus, although users have the inconvenience of wearing a wrist guards, bandages, trousers, and other protective gear, these problems can be solved when using the force-harvesting force machine 10.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. For example, in the embodiment of the present invention, the movable member 200 may be rotated (or rolled) along the longitudinal direction of the guide member 100 while the guide member 100 is being pressed, ). ≪ / RTI > However, the moving coupling structure of the moving member 200 and the guide member 100 can be realized in other ways. The shifting member 200 and the guide member 100 may be coupled by a gear connection structure (not shown). The moving member 200 and the guide member 100 can be implemented with a rack and pinion coupling structure. The pinion gear teeth may be formed on the rotating portion of the movable member 200 and the rack gears engaged with the pinion gear may be formed on the guide member 100. [ Since the shifting member 200 and the guide member 100 are implemented in a gear connection structure, it is possible to prevent a sudden sliding movement of the shifting member 200, and to reduce unnecessary friction phenomena that may occur during sliding, And the guide member 100 can be prevented from being damaged.

Meanwhile, the rotation part and the guide member 100 can be implemented in various forms according to the shape in which the respective contact parts are in contact with each other. Although the embodiment of the present invention has described the convex curved surface in the cross-sectional shape of the contact portion of the guide member 100, the cross-sectional shape of the contact portion of the guide member 100 may be formed in a polygonal structure including a rectangular structure. Also, the cross-sectional shape of the contact portion of the guide member 100 can be formed by an H beam (or I beam) structure. In this case, the shape of the contact portion of the rotating portion can also be formed in various shapes corresponding to the cross-sectional shape of the contact portion of the guide member 100. For example, when the cross-sectional shape of the contact portion of the guide member 100 is formed by the H beam and the polygonal structure, at least the portion of the contact portion of the rotation portion, which is in contact with the contact portion of the guide member 100, As shown in Fig. Also, the guide member 100 may be formed to have a short length corresponding to the size of the moving member 200, if necessary. In this case, the shifting member 200 can be used as a gripping device in a state of being coupled with the guide member 100. [ This also falls within the scope of the present invention.
