The present invention relates to a portable exercise device for assisting the centrifugal exercise, and more particularly, to a portable exercise device for assisting the centrifugal exercise to reduce the exercise load during centripetal exercise and to increase the exercise load during the centrifugal exercise.

In general, centripetal exercise and centrifugal exercise may be performed at the same time during dumbbell exercise, but most therapeutic exercises focus on centrifugal exercise rather than centripetal exercise. However, the use of the same one exercise equipment, such as dumbbells during exercise to distinguish the centripetal movement and centrifugal movement to exercise the skill is required for beginners there is a difficulty in this division exercise.

In this regard, the conventional centrifugal exercise training device (see Korean Patent No. 10-1549078) is to cause the centrifugal contraction movement using the electrical stimulation. However, such a method using the electrical stimulation may create discomfort and anxiety for the user, and there is a problem that it is unclear how the effect on the inside of the body is unknown.

In addition, another conventional device is a device that adjusts the angular velocity of passive and active motion by applying a load to the joint using a motor, which has a disadvantage that the device is bulky and expensive and can be applied only to the designed joint.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the present embodiments are intended to complete the disclosure of the present invention, and the general knowledge in the art to which the present invention pertains. It is provided to fully convey the scope of the invention to those skilled in the art, and the present invention is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In this specification, the singular also includes the plural unless specifically stated otherwise in the phrase. As used herein, the words "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components, steps, and actions.

With reference to Figures 1 and 2, the main use and principle of operation of a portable exercise device for assisting centrifugal motion according to an embodiment of the present invention will be described. 1 is a view showing a process for performing centrifugal exercise and centripetal exercise through a dumbbell. Figure 2 is a conceptual diagram illustrating the principle of taking more exercise load in the centrifugal movement than the centripetal movement through the portable exercise device for assisting the centrifugal movement in accordance with an embodiment of the present invention as a lever principle.

Referring to Figure 1, Figure 1 is a view showing a dumbbell exercise, the upper part is a user holding a dumbbell while bending the arm is a centripetal exercise, the lower part is a centrifugal exercise while the user extends the arm to the outside It looks like.

Thus, in general, centripetal exercise and centrifugal exercise may be simultaneously performed during dumbbell exercise, but most therapeutic exercises focus on centrifugal exercise rather than centripetal exercise.

In order to exercise the centripetal movement and centrifugal movement separately during exercise using the same exercise equipment such as dumbbells, it is difficult for a beginner to effectively perform such a division exercise.

Therefore, there is a need for an exercise device that can reduce the exercise load during centripetal exercise and increase the exercise load during centrifugal exercise so that anyone can easily perform the exercise focused on the centrifugal exercise.

Referring to Figure 2, using the lever principle to look at how to reduce the exercise load in the centripetal exercise, increase the exercise load in the centrifugal exercise.

When the lever moves to the lower side by Rθ by applying an external force of F to the left side of the lever, the force acts on the right side of the lever as P moves on the right side of the lever.

Expressing such a relationship by a formula, the relationship of (work) = (force) (distance) = Prθ = FRθ is established. That is, a relation of P = FRθ / rθ = F (R / r) can be made. In this case, F is a force acting on the lever, P is an exercise load applied to the user.

In other words, if one wants to adjust P, the kinetic load, without changing F, the changeable R must be changed. R is the point of action of the external force applied to the lever.

Therefore, if you want to apply a large exercise load to the user to apply an external force F to a position away from the support point R, if you want to apply a small exercise load to the user may apply an external force F to a position separated by R 'less than R from the support point.

When applied to aerobic exercise and centrifugal exercise using exercise equipment such as dumbbells, the lever becomes the user's arm, the support point becomes the elbow, F is the weight applied to the arm, and P is applied to the user. The kinetic loads, R and R ', represent the distance from the point of support of the weight applied to the arm.

In other words, when the user performs a centripetal exercise, a relatively small exercise load should be applied, and therefore, the weight of the exercise equipment should be applied to R 'which is close to the user side, and when the user performs the centrifugal exercise, a large exercise load should be applied. Should be weighed on the R far from the user.

As can be seen from the above, the centrifugal exercise can be effectively performed if the position of the weight applied to the user in one exercise device can be changed so that a larger exercise load can be applied during the centrifugal exercise.

The portable exercise device for assisting the centrifugal motion according to an embodiment of the present invention described below is an exercise device reflecting this point.
