Cycle type exercise equipment {CYCLE TYPE EXERCISE EQUIPMENT}

The present invention relates to a cycle type exercise device, and more particularly, the handle side and the cycle crank pedal side of the exercise device is combined with the function to enable the upper body movement and the lower body movement while swinging the handle The driving is performed at the same rotational speed, and more particularly relates to a cycle-type exercise mechanism that facilitates the passage at the top dead center or the bottom dead center so that the rotation angle positions of the handle shaft for the handle swing and the cycle crank pedal are kept the same.

In general, as the time to move to a vehicle increases, the time to walk or move gradually decreases, so that the physical movement of the body is extremely insufficient, so that the aging and stiffness of muscles occur and the fatigue is easily felt. It is a major cause of occurrence.

Therefore, by regularly exercising properly, the muscles are strengthened and sweated, which promotes blood circulation and metabolism of the human body, and removes the wastes of the human body through sweating to prevent aging and stiffness of muscles, thereby preventing high blood pressure, diabetes, It is necessary to prevent some adult diseases such as heart disease and obesity.

For this reason, most of the recent fitness exercises are mainly performed indoors rather than outdoors, and usually, a fitness club equipped with a variety of exercise equipments, or a multi-functional fitness exercise equipment is provided in a home or office to perform a proper exercise.

Existing exercise equipments that are generally installed in a health club, home, and office are being used, and these exercise equipments are mainly used for lower body exercise. The health cycle includes a handle portion with a dashboard and a crank type. It consists of a body part equipped with a pedal and an internal rotating device, and a saddle on which the user sits, and is largely divided into an eletric type and a cycle type.

At this time, the haptic type is designed to draw a motion trajectory elliptical, the cycle type is designed to draw a circular, there are advantages and disadvantages in various aspects, such as momentum, how to use, but the present invention, in particular, to improve the cycle type It is related.

Most cycle-type exercise equipments disclosed in the related art are designed to allow an exerciser to exercise according to his or her exercise amount by rotating a heavy disk but applying a brake function to apply pressure.

By the way, these conventional cycle-type exercise device mainly performs the lower body only because there was a disadvantage that the upper body movement is not relatively made.

Accordingly, recently, various types of exercise devices have been disclosed in which a handle swing type and a stepper type are combined, which can also serve as a lower body exercise along with the release of various exercise apparatuses.

As another example, exercise devices incorporating a handle swing type with a cycle type exercise device are also disclosed, and are continuously developing in various forms.

However, in the case of the grafted cycle exercise mechanism, the position of the handle shaft for swinging the handle and the position of the pedal installed on the crank shaft for driving the cycle are not designed with specific conditions, but are designed arbitrarily, so that they vary depending on the product. The disadvantage of this method is that it has an adverse effect due to a lot of force when moving from the bottom dead center to the top dead center.

In other words, although the hands and feet are designed to move together, there are no examples of precisely designed to efficiently operate two grafted exercise equipments because the discs are different in size (usually the driving side is large and the driven side is small). Therefore, in addition to the exact amount of exercise required by the muscle, there is a lot of force consumed to rotate the mechanism unnecessarily, there is a phenomenon that interferes with the movement, causing adverse effects.

Patent Registration 10-0370817 In the case of the registered patent, when the pedal is rotated by the DC motor with the reduction gear device, the handle is moved forward and backward so that the user's foot movement and the arm movement are simultaneously performed.

Therefore, if the tension of the chain 400 is loosened or tightened due to the frequent use of the cycle-type exercise device of the present invention, the user rotates the coupling screw 353 while drawing or pulling in parallel, while rotating the adjustment bolt 361. After adjusting the tension of the chain 400 so as to be able to exercise, the adjustment nut 366 is rotated and fixed. (See FIGS. 2A and 2B)

Because, when the tension of the chain 400 is too tight, the handle 250 and the pedal 340 are not rotated, and when the tension of the chain 400 is too loose, the pedal 340 of the user walking around You will not be able to exercise effectively.

On the other hand, as shown in Figures 5 and 6, the brake disk 500 may be further installed on the first shaft 230 may be configured to adjust the amount of exercise.

Here, adjusting the amount of exercise means to adjust the load on the brake disc 500 to make the rotation of the first sprocket 210 driven through the first shaft 230 heavy or light, thereby providing a force to be applied by the exerciser. That means you can adjust it.

To this end, the brake disk 500 is further provided in the space between the first fixing plate 200 and the auxiliary disk 220b, and a pair of plate magnets 510 are installed to enter the brake disk 500. It may have a form.

That is, the plate magnet 510 can be moved toward the brake disc 500, and the position thereof can be fixed so that the size of the attraction force depends on the opposing area between the plate magnet 510 and the brake disc 500. Since it is different, it is possible to adjust the size of the load when the brake disc 500 is rotated.

Therefore, the brake disk 500 is preferably made of a ferromagnetic material.

More specifically, Figure 6 shows an example of the installation of the plate-shaped magnet 510 to enable this action.

Of course, the illustration of FIG. 6 is merely exemplary and may be modified in various forms. For example, a band brake used in a bicycle can be applied as a load control means.In this case, a load adjusting bolt is installed at one end of the wire for adjusting the braking force of the band brake, and the braking force is adjusted according to the loosening and tightening of the load adjusting bolt. To adjust the load to the desired size.

According to the illustrated example of FIG. 6, a pair of magnet brackets 520 are fixed at one side of the first support frame 100a, that is, at a position corresponding to the position where the brake disc 500 is installed, and the magnet bracket A fixing rod 530 is hinged and fixed to the 520, and a magnet fixing plate 540 is fixed to the fixing rod 530, and a pair of plate magnets 510 spaced apart from each other are fixed to the magnet fixing plate 540. It is fixed.

In addition, a rod bracket 550 is fixed to the rear surface of the magnet fixing plate 540 to move the plate magnet 510, and an adjustment rod 560 is hingedly fixed to the rod bracket 550. A part of the length of the 560 is formed in a circular shape and a thread is formed on the outer circumferential surface thereof, and the self-rotating nut 610 is fastened to the thread, and the self-rotating nut 610 is fixed to the fixed post 600 by an idle. do.

That is, the magnetic rotation nut 610 is installed to rotate in a state caught on one side of the fixed post 600, as shown in enlarged in FIG.

In addition, the fixed post 600 may be fixed on the connection frame (110).

Thus, the length of the adjustment rod 560 can be varied by tightening and loosening the magnetic rotation nut 610, and the position of the magnet fixing plate 540 can be changed by varying the length of the adjustment rod 560. As a result, the position of the plate-shaped magnet 510 can be brought closer to or closer to the brake disc 500 as described above.

According to the present invention having such a configuration, a person who wants to exercise first puts both feet on the pedal 340 while holding the handle 250.

Then, when one of the handles 250 pulls down the opposite pedal 340 while pulling, the force is simultaneously transmitted to the first sprocket 210 and the second sprocket 310 at the bottom dead center, the bottom dead center at the top dead center. The transition from point to top dead center is smoothly rotated and smoothly continued.

In other words, because the hands and feet move together, it is easy to switch between the top dead center and the bottom dead center and it takes less power.

Particularly, since the first sprocket 210 and the second sprocket 310 have a 1: 1 size ratio, the first sprocket 210 and the second sprocket 310 are equally distributed without being biased toward one side when a force is applied, thereby being suitable for achieving the object of the present invention.

By repeatedly performing such a process, the hand swing and the cycle exercise can be performed in parallel with the desired amount of exercise.

In addition, by utilizing the brake function described above, more effective exercise can be performed.

In another embodiment, as illustrated in FIG. 7, the power transmission unit may be modified into a gear coupling form.
