It may have a variable configuration.

As described above, as the length of the lateral frame 310 and the vertical frame 320 is configured to vary, the lateral bias of the bicycle 100 may be made within a predetermined angle. For example, as illustrated in FIG. 4, when the bicycle 100 is inclined laterally to have an inclination angle θ, the rod of the vertical frame 320 when the height of one side end of the lateral frame 310 is increased ( The width of the vertical frame 320 hinged to the side end of the lateral frame 310 is increased because the width 322 is inserted into the tube 324 becomes smaller, and when the height of the other end is lowered, The rod 322 may be configured such that the width of the vertical frame 320 hinged to the side and side ends of the lateral frame 310 is increased by increasing the width introduced into the tube 324.

The exercise device according to the present invention may include a bicycle 100 placed on the treadmill 200 and a bicycle holder 300 on which the bicycle 100 is mounted. In addition, unlike the general indoor cycle, the bicycle holder 300 includes a vertical frame 320 that can be changed in height so that the bicycle 100 has a tilt angle θ in both sides, and thus a simple lower body In addition to exercise, actual bicycle driving practice can be performed. In addition, the vertical frame 320 may support the bicycle 100 so as not to fall laterally according to the predetermined height fluctuation range, thereby preventing the risk of injury due to sideways falling during the bicycle driving practice. can do.

According to one embodiment, the vertical frame 320 may include an elastic portion 330. Accordingly, the degree of change and the intensity of variation of the height of the vertical frame 320 may be adjusted. For example, the elastic part 330 may be configured to limit the penetration width of the rod 322 may be limited in the variable width of the height of the vertical frame 320, and may also be configured to limit the variation strength. . For example, one side end of the rod 322 is connected to the lateral frame 310, the tartan of the rod 322 is inserted into the pipe 324 is connected to the elastic portion 330, The elastic part 330 may limit the penetration width and penetration speed of the rod 322 as it is disposed between the other end of the rod 322 and one inner end of the tube 324.

For example, the elastic portion 330 may be configured as a predetermined spring. That is, the spring is disposed in the tube 324, the degree that the rod 322 is introduced into the tube 324 as disposed between the end of the rod 322 and the end of the tube 324, And intrusive strength. Accordingly, the spring may limit the height fluctuation range of the vertical frame 320 and prevent the sudden height fluctuation, and the damper prevents the sudden inclination of the lateral frame 310 and the sudden lateral inclination of the bicycle. Can play a role. Meanwhile, specific embodiments are not limited thereto, and any connection form may not be excluded as long as the elastic portion 330 restricts the height fluctuation range and the height fluctuation rate of the vertical frame 320.

Preferably, the elastic portion 330 may be configured to enable adjustment of the elastic strength. For example, the elastic portion 330 is composed of a spring, it may be provided with an adjusting portion 340 to adjust the width of the spring by adjusting the degree of pressing the spring on both sides. For example, the adjusting unit 340 is provided on the lower end of the tube 324 is disposed between the lower end of the tube 324 and the spring, the height of the adjusting unit 340 is configured to be variable Therefore, the width of the spring disposed between the rod 322 and the adjustment unit 340, and the degree of compression of the spring by the adjustment unit 340 and the rod 322 is adjusted to the The strength of the spring's resistance to displacement can be configured to vary. Accordingly, when the width of the spring decreases, the rod 322 disposed on the spring is strongly pressed by the spring, and thus the spring can be strongly resisted against the displacement of the rod 322. On the other hand, when the width of the spring increases, the pressing strength of the rod 322 by the spring is reduced, and thus the resistance of the spring to the displacement of the rod 322 may be weakened. Accordingly, the width of the tilt angle θ of the entire bicycle 100 may be adjusted, and the resistance strength to the bias of the bicycle 100 may be adjusted to, for example, an appropriate tilt angle to select an appropriate driving learning difficulty according to the user's skill. θ may be formed.

For example, the adjusting part 340 is disposed below the spring and has a predetermined support part 342 in which a gear groove 344 is formed on one side thereof, and a gear 346 meshing with the gear groove 344. It may be configured to include. Accordingly, as the gear 346 rotates, the support part 342 may be displaced in the vertical direction by the gear groove 344 engaged with the gear 346, and thus the support part 342 and the rod 322. The spacing between and accordingly the pressing strength of the spring can be adjusted.

That is, when the trainee is a beginner step, by adjusting the compression strength of the spring strongly, the tilt angle θ can be reduced and the inclination speed can be kept small to maintain a stable driving practice state. By controlling the strength weakly to have a relatively large tilt angle θ, it is possible to practice driving in an environment similar to a normal bicycle driving state.
