The present invention relates to a reciprocating mechanism, and more particularly to a stepped stepper that can perform aerobic exercise and lower body strength exercise in the room.

In general, gravity is applied to the body when climbing stairs, and the amount of exercise increases greatly in the process of repeatedly contracting the muscles of the lower body to overcome this. Therefore, repetitive stair exercise is more effective for cardiopulmonary function and lower body strength exercise than other exercises.

Recently, in order to obtain the above effects, steppers have been marketed as indoor exercise mechanisms, but these products have only solved the problem of the limitation of the place, it does not solve the other problems of the step movement.

In addition, commercially available steppers move two feet up and down alternately, so the up foot is tilted down, and the down foot is tilted up, rather than the ankle or knee joint.

In addition, there is a limit of height that can be moved by noise generation such as rubber bark and length adjustment by extension / compression of piston cylinder when using it for a long time. There is a problem that is too large.

There is a complementary magnetic stepper, but the product price is high and the left and right scaffold operates independently, there is a large weight disadvantage because each of the magnetic parts on each side.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a reciprocating mechanism of a small size having an effect of climbing a high and high stairs, especially in a narrow room.

 It is also an object of the present invention to reduce the price of the product and to exercise without tilting the foot.

In order to achieve the above object, the present invention includes a reciprocating portion consisting of a linear bush and a shaft to allow the scaffold to move in a vertical straight line;

The reciprocating mechanism according to the embodiment of the present invention, as shown in Figure 1, the power transmission means connected to the foot set 13 of the load setting portion 12, the reciprocating portion 302 fixed to the overall body ( Rotating disk 28 and the magnetic portion 25 for applying magnetic force to the rotating disk 28, the magnetic portion 25 for applying a magnetic force to the rotating disk 28, the magnetic portion 25 by pressing the rotating disk 28 and the magnetic portion Load adjusting unit 301 for adjusting the rotation speed of the rotating disk 28 by adjusting the interval between 25,

A reciprocating part 302 for linearly moving the footrest 13 up and down using the shaft 26 and the bush 27 and the footrest support, and a footrest height adjusting part 303 for adjusting the movement height of the user. It is configured by.
The load adjusting unit 301 includes a wire cable 21, a spring 23, a bolt 22, and a bracket 24.

Hereinafter, each part of the reciprocating mechanism according to the present invention will be described in detail.

First, the load setting unit 12 has a rotary knob as shown in FIG. 1, and when the knob is rotated in one direction or the opposite direction, the magnetic part 25 connected to the other side of the wire cable 21 moves toward the load setting unit 12. Pulled or the original position is to drive the load control unit 301.

The rotating disk 28 is rotatably coupled to a pair of fixing brackets fixed vertically on the upper side of the horizontal base, and further, the footrest 13 is lowered through the power transmission means 29 connected to the footrest 13. Reciprocating rotation drive under the driving force. The rotating disk 28 is preferably made of a metal material that can be affected by the magnetic force.

One end of the magnetic part 25 is connected to the bracket 24 of the load control unit 301 by a hinge so as to be rotatably coupled to one side of the rotating disc 28 with a curvature similar to that of the rotating disc 28. It has a structure having a plate disposed adjacently. On the inner circumferential surface of the plate, a plurality of magnetic pieces are arranged in a row to transfer the magnetic force to the rotating disk 28 to increase or decrease the rotating load of the rotating disk 28.

The plurality of magnetics are better to use a magnetic magnetic neodymium.

The load control unit 301 is coupled to the bracket 24 fixed to the shaft of the rotating disk 28 so that the magnetic portion 25 is rotatable by a hinge pin, and at the same time the fixing bolt 22 and the nut and the spring By connecting to each other at 23, the magnetic portion 25 is brought closer or further away from the rotating disk 28 by the load setting portion 12 so that the distance is adjusted.

To this end, the load adjustment unit 301, the wire of the wire cable 21 is fixed to one side of the magnetic portion 25 and the outer shell of the wire cable 21 is fixed to the bracket 24.

First, the load setting unit 12 may set the strength of the strength, for example, from 1 step to 8 steps, and in the initial state, the rotation of the rotating disk 28 by transferring the load to the rotating disk 28 to a minimum. Position the magnetic portion 25 away from the rotating disk 28 to smoothly.

In the initial state, when the rotary knob of the load setting unit 12 is set to a position corresponding to the first stage of strength, the wire cable 21 is pulled so that the load adjusting unit 301 rotates the magnetic part 25 to the rotating disk 28. By keeping it away from the magnetic forces of the multiple magnetics.

When the intensity of the exercise is increased in such an initial state, for example, when the user sets the rotary knob of the load setting unit 12 to eight levels of maximum intensity, a spring connected to the bracket 24 of the load adjusting unit 301 is used. By the restoring force of (23), the magnetic portion 25 is pressed to a close contact with the rotating disk 28.

Therefore, the plurality of magnetic coupled to the inside of the magnetic portion 25 is adjacent to the rotating disk 28 while applying a strong magnetic force to the rotating disk 28 to apply a rotating load to the rotating disk 28.

Thus, the reciprocating mechanism according to the present invention is to press the magnetic portion 25 close to the rotating disk 28, or vice versa, the magnetic force applied to the rotating disk 28, i. By adjusting, the user can freely set the intensity of the exercise from step 1 to step 8.
