         On the other hand, the rowing exercise mechanism is installed on both sides of the body frame.

         The rowing mechanism has a pair of drive levers 42, and the drive levers 42 are attached to the bars 18 of the body frame 20 so as to rotate by the hinges 50, respectively. A chain 43 is connected to an end of the drive lever 42, a spring 44 is connected to an end of the chain 43, and a spring 44 for restoring force is fixed to the cross bar 23.

         A cradle 72 for mounting the driving lever 42 is provided.

         The rear wheels 52 are fixed to both sides of the rear wheel shaft 31 and fixed to the crosspiece 24 by bearings of the rear wheel shaft 31. The gear 32 is fixed to the center of the rear wheel shaft 31.

         In front of the rear axle 31 is a drive shaft 33 engaged with the gear 32 and a shaft 35 to which the ratchet wheel 34 is fixed. The shaft 35 is supported by the bearing in the body frame 20. do. A similar configuration is provided in the rear of the rear axle 31 with a gear shaft 55, a ratchet wheel 54, a drive gear 53, a transmission gear 63, and a transmission shaft 65. ) Is configured to transmit the driving force to the rear wheel shaft 31 when moving forward and rearward.

         FIG. 2 is an exploded perspective view of the land control mechanism of the present invention, and will be comprehensively described with reference to FIG. 3. Chair 40 of the present invention is provided with sliding blocks (45, 46) guided by the guide rods (25, 26) at the bottom. And the push rod 47 is fixed to the lower rear of the chair 40. A gear 48 is formed on the lower surface of the pusher 47 and the gear 48 meshes with the front ratchet wheel 34 of the shaft 35 and the rear ratchet wheel 54 of the shaft 55 simultaneously.

         The rear drive gear 53 close to the rear ratchet wheel 54 is gear-coupled with the transmission gear 63 and the transmission gear 63 is coupled to the gear 32 to transmit power.

         The front ratchet wheel 34 rotates in the clockwise direction when the pusher 47 moves backwards and transmits power, and rotates counterclockwise when moving forward, and idles without transmitting power. The cheat wheel 54 rotates counterclockwise when moving forward and transmits power, and rotates clockwise when moving backward and does not transmit power.

         Springs 27 and 28 are installed at the front and rear of each of the guide rods 25 and 26 to reduce the impact of the chair 40 hitting a pair of fasteners at the front and rear of the guide rods 25 and 26 and to the chair 40. In order to give a reaction force, on the other hand, on both sides of the front wheel 12 is provided with a footrest 14 that can push the body on the foot.

         The operation of the land control mechanism of the present invention as described above will be described.

         First, a method of riding the land control mechanism while rowing using the drive lever 42 will be described.

         The occupant holds the chair 40 and both feet are placed on the footrest 14 of the front wheel 12 to adjust the direction of the bicycle.

         Both hands of the occupant hold the drive lever 42 and pull the handle back.

         Then, the chain 43 connected to the drive lever 42 rotates the ratchet sprocket 36 in the clockwise direction and the rotational force is transmitted to the drive gear 33 through the shaft 35.

         The drive gear 33 rotates the gear 32 of the rear wheel shaft 31 counterclockwise, so that the rear wheel 52 rotates forward.

         When the occupant pushes the drive lever 42 forward, the chain 43 moves by the spring 44 and the ratchet sprocket 36 rotates counterclockwise but does not transmit rotational force to the shaft 36.

         Therefore, the drive lever 42 transmits the rotational force to the rear wheels only when the drive lever 42 is pulled, so that the handle can be used as a rowing paddle of the adjustment mechanism.

         Next, a method of riding the land control mechanism by moving the chair 40 forward and backward will be described.

         The occupant holds the handle 10 with both hands and puts the feet on the footrest 14. Push back the chair 40 while stretching the legs. Then, the push rod 47 of the chair 40 moves to the rear. When the pusher 47 is moved backward, the front ratchet wheel 34 rotates clockwise, and the front drive gear 33 coupled to the front ratchet wheel 34 and the front shaft 35 also rotates clockwise. The gear 32 fixed to the rear wheel shaft 31 and coupled to the front drive gear 33 rotates counterclockwise to transmit driving force. Therefore, the rear wheels 52 fixed to the rear wheel shaft 31 rotate forward in the counterclockwise direction.

         When the leg is bent and the chair 40 is pulled forward, the push rod 47 of the chair 40 moves forward. When the push rod 47 moves forward, the rear ratchet wheel 54 rotates counterclockwise, and the rear drive gear 53 coupled to the rear ratchet wheel 54 and the rear shaft 55 also counterclockwise. The transmission gear 63 which rotates and is fixed to the transmission shaft 65 and engaged with the rear drive gear 53 rotates clockwise and is fixed to the rear wheel shaft 31 and is coupled to the transmission gear 63. ) To transmit the driving force by rotating it counterclockwise. Therefore, the rear wheels 52 fixed to the rear wheel shaft 31 rotate forward in the counterclockwise direction.

         More preferably, the front drive gear 33 transmits the driving force when the pusher 47 moves rearward, and transmits power when the clockwise rotation is rotated, and when the counterclockwise rotation rotates, idling the power without the need for frictional force. The transmission gear 63 transmits the driving force when the pusher 47 moves forward. The transmission gear 63 transmits the power when the clockwise rotation is rotated. It is possible to prevent exhaustion, and the rear drive gear 53 transmits a driving force when the pusher 47 moves forward, and transmits power in a counterclockwise rotation and idles when rotated in a clockwise direction. The power can be prevented from being consumed by frictional force.

         However, when climbing up a hill, the reverse drive should be impossible, but if the front drive gear 33, the transmission gear 63, and the rear drive gear 53 are latched, the front drive gear 33 cannot be pushed back. Fixing or fixing the rear drive gear 53 can be prevented from being pushed back.

         In the above, the driving lever 42 is rotated by the force of the arm to advance the land control mechanism, and the chair 40 is moved forward and rearward by the force of the leg to advance the land control mechanism, but the steering is performed by the foot. At the same time, it is a whole body exercise apparatus capable of driving the land control mechanism using the arms and legs.

         3, the push rod 47, the front ratchet wheel 34, the rear ratchet wheel 54, the transmission gear 63, the front drive gear 33, the rear drive gear 53, the gear 32 of the present invention are shown in FIG. ) Is a diagram showing the coupling relationship in detail.

         The chair 40 moves forward and backward and shows a configuration that transmits the driving force to the rear wheel 52. In order to increase the speed at which the chair 40 moves forward and rear relatively, the rotation speed is greater when the diameters of the front drive gear 33 and the rear drive gear 53 are larger than the diameter of the gear 32. If you increase the relatively large diameter of the gear 32 to obtain a small rotational speed can change the diameter of the gear according to the body shape and force of the person can choose the speed to move forward. In addition, the diameter of the front ratchet wheel 34 and the rear ratchet wheel 54 coupled to the push rod 47 can be made relatively small, thereby increasing the rotation speed of rotation. In this step, the rotational speed can be selected according to the diameter of the gear 32 and the diameter of the front drive gear 33 and the rear drive gear 53.

         When the pair of rear wheels 52 are fixed to both rear axles 31, it is difficult to smoothly rotate the land control mechanism, so that only one of the rear wheels 52 is fixed to the rear axles 31 by the rotation radius. In addition, a planetary gear, also called a differential gear or a differential gear, which is a type of gear transmission, may be adopted to smooth the rotation.

         4 is a view showing another embodiment of the present invention showing the configuration of another embodiment of the configuration for advancing the land control mechanism by rotating the drive lever 42 using the arm.

         The ends of the pair of drive levers 42 are coupled to the crosspiece 24 by the hinge 78 and are configured to rotate about the hinge 78, and the rotary gears coupled to both ends of the shaft 35 ( An arc gear 76 engaged with 74 is coupled to the side of the drive lever 42.

         When the occupant holds the drive lever 42 by hand and rotates upward, the arc gear 76 rotates in a counterclockwise direction, and the ratchet gear 74 geared with the arc gear 76 rotates in a clockwise direction so that the shaft By rotating the clockwise (35) to transmit the driving force and to the gear 32 coupled to the gear 32 is geared to the drive gear 33 fixed to the shaft 35 to transmit the rotational force in the counterclockwise direction. At this time, if the gear diameter of the rotary gear 74 is smaller than the moving angle of the arc-shaped gear 76, the high angular velocity can be transmitted to the shaft 35. If necessary, the diameter of the ratchet gear 74 can be small or large. To select the speed of the onshore coordination mechanism.

         Figure 5 is a view showing another embodiment of the present invention, showing a structure that can perform the whole body movement on the rail and ride the land adjustment mechanism, the lower both sides of the handle portion 16 in place of the front wheel 12 of the present invention Two wheels 37 are rotatably installed at the two wheels, and two wheels 37 are installed at both sides of the rear wheel shaft 31 in the form of a flywheel for railways instead of the rear wheels 52.

Since the four wheels 137 replacing the front wheels and the rear wheels move along the rail 50, the land control mechanism mounted on the rail 50 has a relatively low frictional force and also uses the foot on the foot plate 94 to control the steering. It is a configuration that can double the speed by using the force is no longer necessary.

         As such, when the wheels move along the rails 50, the wheels are automatically switched in structure and not overturned or separated, thereby ensuring safety.

         Although the embodiments of the present invention have been described in detail as described above, the scope of the present invention is not limited thereto, and the scope of the present invention extends to the range substantially equivalent to one embodiment of the present invention. will be.

         The land adjustment mechanism of the present invention configured as described above can achieve the same effect as rowing the adjustment mechanism by pulling the handle like a rowing and moving the whole body back to transmit the momentum. The present invention is to provide an efficient exercise device that can combine the effective exercise and the sense of speed in the configuration capable of whole body movement, such as exercise of the leg muscles and abdominal muscles of the arm muscles.
