3 is an exploded perspective view of a second wheel part of a pair of wheel parts for explaining the operation principle of the bicycle exercise device according to an embodiment of the present invention.

Referring to FIG. 3, the first rotation part 130 disposed at the center of the second wheel part 125 may include the first unevenness 132, the third unevenness 133, the fourth unevenness 134, and the third unevenness. The first rotating plate 136 and the second rotating plate 137 may be included.

The first rotating plate 136 is formed in a circular shape so that the first unevenness 132 is formed on the outside of the first rotating plate 136 along the circumference, and the inside of the first rotating plate 136 is located along the circumference. Third unevenness 133 may be formed. In this case, the third unevenness may be formed as a triangle angularly oriented in one direction.

The second rotating plate 137 may be formed in a circular shape, and a central axis 138 formed at the center of the second rotating plate 137 may be combined with a hole formed at the center of the first rotating plate 136 to allow the first rotating plate 137 to be formed in a circular shape. It may be disposed on the rotating plate 136.

In addition, the second rotating plate 137 may have a fourth unevenness 134 corresponding to the third unevenness 133. The fourth unevenness 134 may be formed as a triangle in which the angle is biased in a direction opposite to the third unevenness 133.

In order to drive the bicycle exercise device 100, the first footrest part 150 or the second footrest part 155 is pressed using a user's foot. When the first scaffolding part 150 is pressed down, when the first scaffolding part 150 is lowered, the second unevenness 142 of the first power transmission part 140 is the first unevenness 132. Meshes with. In addition, the second scaffold 155 is lifted up by the seesaw motion of the support 162.

When the first concave-convex 142 and the first concave-convex 132 are rotated in one direction, the third concave-convex 133 formed inside the first rotatable plate 136 may also be formed. It is engaged with the fourth unevenness 134 formed on the outside of the second rotating plate (137). Thus, the second rotary plate 137 is rotated in one direction while the surface erected at right angles to the third unevenness 133 and the surface erected at right angles to the fourth unevenness 134.

On the other hand, when the second footrest unit 155 is pressed using the user's foot, the first footrest unit 150 is lifted up. When the first scaffolding part 150 is raised, the second unevenness 142 of the first power transmission part 140 meshes with the first unevenness 132 and the first rotating plate 136 is rotated in the other direction. .

In addition, the third unevenness 133 and the fourth unevenness 134 formed in the first rotating plate 136 are engaged with each other. At this time, when the third concave-convex 133 rotates in the other direction and rotates along the inclined surface of the fourth concave-convex 134, the fourth concave-convex 134 is pressed while a part of the second concave-convex plate 137 is rotated. It will go inside. Thus, the third unevenness 133 does not mesh with the fourth unevenness 134 so that the second rotating plate 137 does not rotate in the other direction.

As such, only when the first rotating plate 136 is rotated in one direction, the second rotating plate 137 is rotated and power is transmitted to the second wheel part 125, whereby the first rotating part 130 and the second rotating part 137 are rotated. The rotation unit 135 does not cross, and sequentially transfers power to the second wheel unit 125 to drive the bicycle exercise device 100.

It may further include a second adjusting unit 166 disposed.

When the second adjustment unit 166 is rotated in the first direction, the critical rotational force is increased, so that the seesaw movement of the support unit 162 is not easy. Therefore, the force required for the user to operate the first footrest 150 and the second footrest 155 is increased, and the load applied to both legs of the user is increased, thereby enhancing the exercise intensity.

When the second adjusting unit 166 is rotated in the second direction, the critical rotational force is reduced, so that the seesaw movement of the support unit 162 becomes easy. Therefore, the force required for the user to operate the first scaffolding part 150 and the second scaffolding part 155 is reduced, and the load applied to both legs of the user is reduced, thereby reducing the exercise intensity.

As such, by adjusting the critical rotational force by rotating the second adjustment unit 165, the user can exercise at a desired intensity.

As described above, according to the bicycle exercise device according to the present invention, even when moving a relatively short distance by using a pair of scaffolding unit connected to a pair of power transmission unit moving up and down according to the vertical movement of the user's legs It can provide a bicycle exercise equipment that can increase the.
