Since the two drive rods are simultaneously operated, the pendulum movement of the saddle strut and the handle strut always continuously and smoothly moves. Therefore, when the user performs a horse-style exercise, the movement is natural and the user can use it comfortably.

  As shown in FIGS. 1 and 2, the structure of the exercise bike according to the present invention includes a pedestal 10 and the following parts.

  One end of the pendulum rod 20 is fixed to the front end of the base 10 by the shaft sheath 201 and swings back and forth.

  The handle column 30 and the saddle column 40 are integrated, a handle 301 is installed above the front end, and the lower side is axially connected to one end of the pendulum rod 20 by a shaft sheath 302. A saddle 401 is installed at the rear end.

  As shown in FIG. 3, the first drive device 50 includes a rotary shaft unit 501, and the rotary shaft 5011 is fixed to the rear portion of the base 10 by a rotary shaft base 5012. The drive wheel 502 is installed at one end of the rotating shaft 5011 of the rotating shaft unit 501.

  Similarly, as shown in FIG. 3, the first drive rod 60 is attached so that one end of the first drive rod 60 penetrates one side surface of the rear end of the rear portion of the handle column 30 and the saddle column 40 in an integrated manner. ing. The other end is in a state of being freely rotated by the fixed yoke 601, and an eccentric portion of one end of the rotating shaft 5011 of the first driving device 50 (of which, in the present invention, one end of the rotating shaft 5011 is fixed to the stationary platen 5013. In this embodiment, the first drive rod 60 is fixed at an eccentric position.

  As the rotary shaft 5011 rotates, the side surfaces of the rear ends of the handle column 30 and the saddle column 40 are pushed or pulled. Among them, a buffer unit 602 (a spring part or a buffer unit made of polyurethane) is installed at a connecting portion between the handle column 30 and the rear end of the saddle column 40.

  As shown in FIGS. 3 and 4, one end of the second drive rod 70 is axially connected to one side of the rear end of the rear portion of the handle column 30 and the saddle column 40 in a state where the second drive rod 70 swings to the left and right by a fixed hammer 701. . The other end is fixed to the eccentric portion of the other end of the rotating shaft 5011 of the first drive device 50 in a freely rotating state by a fixing pin 702. As the rotary shaft 5011 rotates, the other side of the rear end of the handle column 30 and the saddle column 40 is pushed or pulled.

  As shown in FIGS. 5, 6, and 7, the first drive rod 60 has different eccentric positions on both sides of the first drive device 50 (the eccentric angles Q and Q ′ shown in FIG. 5 are different). The eccentric distances B and B ′ shown in FIG. 6 are different) and the same (the eccentric angles and distances shown in FIG. 7 are the same).

  The second driving device 80 is provided with a gravity wheel 801 having an appropriate weight, and is installed on the pedestal 10 while being freely rotated by the rotating shaft 802.

  The drive wheel 803 is attached to the rotation shaft 802 coaxially with the gravity wheel 801. The transmission belt 804 is placed between the driving wheel 803 and the driving wheel 502 of the first driving device 50 to interlock the driving wheel 502 and the gravity wheel 801.

  Since the diameter of the driving wheel 803 is much smaller than the driving wheel 502 of the first driving device 50, a very large speed difference occurs between the two. Furthermore, the gravitational wheel 801 also generates a very large speed difference from the driving wheel 502.

  The spring part 90 is installed between the handle column 30, the saddle column 40, and the pedestal 10, so that the rear ends of the handle column 30 and the saddle column 40 jump up at any time.

  The pedal rod 91 is installed on both sides of the saddle column 40 so that the user can place both feet.

  As shown in FIGS. 8 and 9, the exercise bike according to the present invention has an integrated handle column 30 and saddle column 40 at the rear end of the rotating shaft of the first drive unit 50 by two drive rods 60 and 70. 5011 It connects with the eccentric part of both sides. Then, the spring part 90 receives the action, swings upward at any time, and reaches the highest point. The front end is also connected to the base 10 by a pendulum rod 20 that swings back and forth.

  Therefore, when the user sits on the saddle 401 and puts both feet on the pedal rod 91, the rear end of the handle column 30 and the saddle column 40 descends by its own gravity, and the drive rods 60 and 70 are fixed eccentrically. The rotating shaft 5011 of the first drive device 50 is rotated by the trajectory, and at the same time, the front end of the handle column 30 and the saddle column 40 moves the pendulum rod 20 about the shaft sheath 201 of the pendulum rod 20, Along with it, it performs a pendulum movement.

  Further, the driving wheel 502 of the rotating shaft 5011 of the first driving device 50 simultaneously moves the gravity wheel 801 of the second driving device 80 by the transmission belt 804 during rotation. The gravity wheel 801 also has a slightly heavier weight, and the drive wheel 502 of the first drive device 50 has a slightly larger speed ratio (that is, the rotation speed of the gravity wheel 801 is faster than the drive wheel 502). When the steering column 30 and the saddle column 40 of the first driving device 50 are lowered and the rotating shaft 5011 of the first driving device 50 is rotated, the gravity wheel 801 of the second driving device 80 rotates at a high speed, and a rotational force due to extremely large inertia is generated. Have. Further, the rotational force due to inertia is also transmitted to the drive wheel 502 of the first drive device 50 by the transmission belt 804, and the rotary shaft 5011 provides the auxiliary rotational force.

  Then, when the above-mentioned user falls by the gravity of the rear end of the handle column 30 and the saddle column 40, the user simply applies a little force to the handle column 30 and the saddle column 40 with his buttocks, waist, legs or hands. (For example, force is applied to the saddle 401, the pedal rod 91, or the handle 301).

  Then, a larger driving force is applied to the rotating shaft 5011 of the first driving device 50 to generate a larger rotating force. Accordingly, the gravity wheel 801 of the second driving device 80 provides a rotational force due to a larger inertia to the driving wheel 502 and the rotating shaft 5011 of the first driving device 50, and the spring part 90 is provided with the handle column 30 and the saddle column 40. The drive rods 60 and 70 that are naturally fixed eccentrically on both sides of the rotary shaft 5011 of the first drive device 50 by providing a force that springs up from time to time on the rear tip, can be quickly and smoothly Do exercise and jump up.

  Along with this, the rear ends of the handle column 30 and the saddle column 40 are pushed up, and the pendulum operation of the front ends is performed. In this way, the circulating motion is continuously performed, and the handle column 30 and the saddle column 40 perform a pendulum motion up and down and up and down like dancing.

  In addition, the user sitting on the saddle 401 can feel the sensation of riding as if he / she is riding, so that he / she fulfills the purpose of the expected whole body exercise, and moreover, the operation of the exercise bike is more versatile. Has the effect of being rich and varied and interesting.

  As shown in FIGS. 5, 6, 10, and 11, the first drive rod and the second drive rod 70 are not the same in eccentric positions that are fixed on both sides of the rotation shaft 5011 of the first drive device 50. . Further, the second drive rod 70 is also axially connected to the side surface of the rear end of the rear portion of the handle column 30 and the saddle column 40 by 702.

  Further, in order to cause the handle column 30 and the saddle column 40 to perform a pendulum motion to the left and right, when the handle column 30 and the saddle column 40 are moved and perform a pendulum motion back and forth and up and down like a dance, The pendulum motion is moved from side to side. Accordingly, the first drive rod 60 and the second drive rod 70 are not at the same eccentric position fixed on both sides of the rotary shaft 5011. Therefore, as the rotary shaft 5011 rotates, they also have an asymmetric altitude and position. 30 and the rear end of the saddle column 40 are pushed or pulled.

  Further, since the second drive rod 70 and the handle column 30 and the saddle column 40 are connected to each other in a shaft connection state that can swing left and right, the drive rods 60 and 70 at two different altitudes and positions at the same time as the rotation shaft 5011 rotates. In addition, the left and right pendulum movements are automatically performed by pushing or pulling the rear ends of the handle column 30 and the saddle column 40.

  As described above, when the handle column 30 and the saddle column 40 swing back and forth and up and down as if dancing, they can swing right and left at the same time and experience a state as if the user is riding. Therefore, the operation is diversified, and there are effects that are rich in fun and change, and at the same time, the expected exercise effect can be obtained.

  As illustrated in FIG. 7, the first drive rod 60 and the second drive rod 70 have the same eccentric positions on both sides of the rotation shaft 5011. Therefore, the handle column 30 and the saddle column 40 also swing back and forth and up and down as if dancing, but do not swing left and right.

  Since the buffer unit 602 is provided at the connection point between the first drive rod 60 and the handle column 30 and the rear end of the saddle column 40, the handle column 30 and the saddle column 40 are pushed and pulled by the first drive rod 60. Accordingly, the user sitting on the saddle 401 is more comfortable and can perform natural operations.

  As described above, the structure of the exercise bike according to the present invention is simpler than the exercise bike which is a conventional indoor exercise equipment, but its movement and operation are diverse and innovative.
