When one of the one-way bearings causes the right driven wheel 2 1 to rotate in one direction, the left driven wheel 2 2 rotates in the other direction, and the middle driving wheel 23 is always fixed in one direction. 8 200829306 The right drive shaft 3' is attached to the right bracket 1 1 and the right drive wheel 3 1 is disposed on the inner side of the right bracket 1 1 and has a right belt 3 2 The right driving wheel 3 1 and the right driving wheel 2 1 are wound around the right driving wheel 3 1 so that the right driving wheel 3 1 can drive the right driving wheel 2 1 . The left driving shaft 4 is disposed on the left bracket 12, and the left driving wheel 4 1 is disposed on the inner side of the left bracket 12 by the left driving shaft 4, and a left belt 4 2 is coupled. The left driving wheel 4 1 and the left driving wheel 2 2 are wound around the left driving wheel 4 1 so that the left driving wheel 4 1 can drive the left driving wheel 2 2 . a resistance mechanism 5 is disposed on a bracket 13 of the base 1. The resistance mechanism 5 includes a middle driven wheel 53, a pulley 51, and a weight wheel 52 driven by the pulley. The pulley 5 1 and the middle driven wheel 53 are coaxially disposed on the bracket 13 , and another middle belt 54 is pressed by an idler pulley 5 5 , and the twisting is disposed around the middle driving pulley 23 and the middle The moving wheel 5 3 causes the middle driving wheel 23 to drive the middle passive wheel 53. a right arm 3 3 , wherein the right arm 3 is disposed on the outer side of the right bracket 1 1 , and the right arm 3 3 is provided with a right pedal at one end of the right arm 3 3 4, the right pedal 34 is pivotally disposed at one end of a right lever 35, and the other end of the right lever 35 is pivoted to one side of the base 1. The other end of the right arm 3 3 is pivotally disposed at one end of a right rear lever 36, and the other end of the right rear lever 36 is pivotally provided with a right swing arm 37', and the bottom end of the right swing arm 37 is pivoted The other end of the right arm 3 3 is further disposed at one end of a right front rod 38, and the other end of the right front rod 38 is framed by a right crank 309. The right crank 3 9 is further disposed on a middle bracket 14 , and the middle bracket 14 is disposed on the front portion of the base 1 . 9 200829306 Again, the right swing arm 3 7 is driven by the right pedal 34. a left arm 4 3 , wherein the left arm 4 is disposed on the outer side of the left bracket 1 2 , and the left arm 4 3 is provided with a left pedal 4 4, the left pedal 44 is disposed at one end of a left side lever 45, and the other end of the left side rod 45 is pivotally disposed on the other side of the base 1, the left arm 43 The other end is pivotally disposed at one end of a left rear lever 46, and the other end of the left rear lever 46 is pivotally provided with a left swing arm 47 and the bottom end of the left swing arm 47 is dragged to the base 1. On the other side, the other end of the arm 4 3 is further pivoted at one end of a left front rod 48, and the other end of the left cup 4 8 is pivoted to a left crank 4 9, the left crank 4 9 and The right crank 3 9 series is correspondingly disposed on the middle bracket i 4 , that is, like the double crank of the bicycle. Furthermore, the left swing arm 7 7 is driven by the left pedal 4 4 . The seat 6 is disposed on the base rear portion of the base. When the structure of the embodiment is used, referring to FIG. 2 to FIG. 5, when the right pedal is stepped down to the right pedal 3 4, the right pedal 3 4 will drive the right branch 3 3 The top swings forward, and at the same time, the right driving wheel 3 i is rotated forward, and the ΜA moving wheel 2 1 is rotated forward. Since the middle driving wheel 2 3 and the right driven wheel 2 1 are concentric, the middle driving wheel 2 3 is also simultaneously Rotate forward and drive the middle passive wheel 5 3 to turn 'the middle passive wheel 5 3 - is rotated and also drive the pulley 5 1 and the heavy 1 wheel 5 2 ' and the weight wheel 5 2 is caused by the weight of the weight wheel 5 2 In addition, since the direction of rotation of the one-way bearing installed in the right driven wheel 2 1 is opposite to that of the one-way shaft 200829306 installed in the left driven wheel 2 2 , the left passive wheel 2 2 will Driven by the rotating shaft 2 and rotated backwards, and the left driving wheel 4 1 is also rotated backwards, the left driving wheel 4 1 is rotated backwards, and the top end of the left arm 4 3 is also swung backwards, and the left pedal 4 4 is naturally oriented toward the user. Moving backwards. On the other hand, when the right pedal 34 is stepped forward and the top end of the right arm 3 3 is swung forward, the bottom end of the right arm 3 3 moves the right rear lever 36 and the right front lever 38 to move backward. The right swing arm 3 7 is oriented toward the user and swings backward, and the right front lever 38 also drives the right crank 3 9 is rotated backward, since the right crank 39 and the left crank 49 are alternately disposed on the middle bracket 14 , at this time, the left crank 49 rotates forward and pulls the left front rod 4 8 and the left rear rod 4 6 to move forward. Connecting the left swing arm 47 to the user direction and swinging forward 5 also drives the bottom end of the left arm 43 to swing forward, while the top end of the left arm 43 swings backward, similarly making the left pedal 4 4 naturally oriented. The user moves in the direction and moves backwards to complete the whole operation. Of course, when the user steps forward the left pedal 4 4, the right pedal 34 also moves backwards toward the user, and the right swing arm 37 is away from the user. Swing forward and the left swing arm 47 moves rearward toward the user. Thereby, the user continuously cycles back and forth and swings the arms to achieve the double movement effect of the hand and the foot. It can be seen from the description of the above embodiments that the present invention is mainly characterized by the mechanical design of the transmission mechanism, and the transmission mechanism includes two driving wheels, two passive wheels and one middle driving wheel, and the two driving wheels are respectively driven by a driving shaft, and The driving directions of the two driving wheels are different, and the two passive wheels and the middle driving wheel are coaxially arranged on one rotating shaft, and the two passive wheels are respectively driven by the driving wheels. When the two pedals 11 200829306 are reciprocating with each other, the system rotates respectively. The side wheel corresponds to the driving wheel, and the two side arms of the same side are oscillated to provide a composite movement of the user's hand and foot. Therefore, the present invention has the following advantages: The mechanical design of the transmission mechanism of the present invention makes the overall space design freedom of the device better. Since the transmission mechanism and the resistance mechanism can be designed to use the front half space of the base of the device, the seat is installed at a relatively free position, and the overall space utilization is better, when the transmission mechanism and the resistance mechanism are to be repaired. 'There is no need to remove the seat, it can be repaired directly. The above description of the embodiment is used to explain the present invention, and is not intended to limit the present invention. Therefore, the numerical value is changed or the equivalent component is The invention is described in detail above, and it can be understood by those skilled in the art that the present invention has been achieved in accordance with the provisions of the patent law, and the patent is to be described in the following.
