This configuration related to the coiling drum is widely known in the related art, so a detailed description is omitted.

The schematic operation of the present invention having such a configuration will be schematically described with reference to the accompanying FIG. 7 and the above-described description.

First, as shown in FIG. 1, the user is seated in the seat 43 in a state where the ends of the seat 43 wire 76 are connected. In the state seated on the seat 43, the user holds the handle 412 and presses the pedal 466 in one direction with both feet. The external force applied to the pedal 466 in one direction is transmitted as a rotational force to the drive sprocket 46 and is transmitted to the first driven sprocket 47 through the movable chain 462.

When the rotational force is transmitted to the first driven sprocket 47, it rotates the first movable rod 44 and accordingly each of the second driven sprockets 48 located on the left and right sides of the first movable rod 44 is as shown in the figure.

That is, it does not simply rise upward, but rises in the direction in which the body is pushed forward by the user's weight.

The lowering of the lifting unit and the movable unit may be performed in such a way that the user applies the external force in the opposite direction to the pedal 466. That is, when the user presses the pedal 466 in the other direction, each of the second driven sprockets 48 rotates in the other direction, and each of the third driven sprockets 49 rotates in one direction, and thus the first and second lifting chains 52 , 56) Each is pulled upward. Accordingly, the lifting unit and the movable unit gradually descend vertically downward along the first and second vertical beams 22 and 26.

When the lifting portion and the moving portion descend, the external force in one direction acting on the rotating portion decreases as the vertical height of the user seated in the seat 43 decreases. When the external force in one direction acting on the rotating portion decreases, the elastic body 63 gradually pushes the movable body 62 by its restoring force, and finally the movable body 62 returns to its original position, and the user descends to the initial position. will be.

Accordingly, the second movable rod 141 rotates in one direction.

When the second movable rod 141 rotates in one direction, each of the first and second pinion gears 142 and 143 engaged with the first and second rack gears 54 and 58 rotates in one direction, and thus lifts and lowers. The moving parts and the moving parts gradually rise vertically upward along the first and second vertical beams 22 and 26. As described above, the user simply moves on the pedal, and the user vertically rises while sitting on the seat.

At this time, since the rotating portion is provided at the lower portion of the first horizontal beam 12, when the vertical height of the user increases, the horizontal beam portion and the vertical beam portion structure are naturally inclined forward from the rotating portion as a starting point due to the weight of the user. It is the same as the above-described embodiment that the user sitting at (43) does not rise vertically, but rises at a certain angle forward with respect to the pivot.

When the user presses the pedal 466 in the other direction and applies an external force in the opposite direction, the first driven sprocket 47 rotates in the other direction, and the first engaged with the first and second rack gears 54 and 58 respectively , As each of the two pinion gears 142 and 143 rotates in the other direction, the elevating unit and the movable unit gradually descend vertically along the first and second longitudinal beams 22 and 26.

When the lifting portion and the moving portion descend, the external force in one direction acting on the rotating portion decreases as the vertical height of the user seated in the seat 43 decreases, and the elastic body 63 moves the moving body 62 by its restoring force. Is gradually pushed out, and finally, while the movable body 62 is returned to its original position, the user descends to the initial position and the use for the present invention ends.

In the above, the present invention has been described in terms of preferred embodiments, but this is only an example, and the present invention is not limited thereto, and may be implemented by being modified in various ways. It will be apparent that it can be carried out in addition.
