DETAILED DESCRIPTION OF THE INVENTION

[0022] The invention is further described in combination with the drawings and specific embodiments as follows.

[0023] As shown in FIGS. 1-5, an exercise machine with boating and riding exercise effects includes a base 1, a cushion 2, a left pedal 3, a right pedal 31, a rotary rod 4 and a supporting rod 5. The base 1 is approximately in an H shape. Two rolling wheels 11 are disposed on the lower portion of the front end of the base 1 so that the whole exercise machine can be dragged to be stored. A protruding frame 12 extends upwards from the middle of the front end of the base 1. A left horizontal dowel pin 13 is arranged on the left side of the protruding frame 12. The left pedal 3 is rotatably disposed around the left horizontal dowel pin 13. A right horizontal dowel pin 131 is arranged on the right side of the protruding frame 12. The right pedal 31 is rotatably disposed around the right horizontal dowel pin 131.

[0024] The front end of the rotary rod 4 is hinged to the protruding frame 12 at the front end of the base 1. The cushion 2 is slidably connected to the rotary rod 4. Particularly, the cushion 2 includes a cushion plate 21 and a second n-shaped frame 22 fixedly connected to the lower side of the cushion plate 21. Two cushion wheels 23 are disposed on each of two inner side faces of the second n-shaped frame 22. A cushion guide groove 41 is formed in each of two side faces of the rotary rod 4. Each cushion guide groove 41 is matched with the two corresponding cushion wheels 23. A front limiting stopper and a rear limiting stopper are arranged on each cushion guide groove 41 and used to limit the sliding distance of the cushion 2.

[0025] A supporting rail 14 is arranged on the base 1. Guide grooves 141 are respectively formed in two sides of the supporting rail 14. A sliding frame 6 is cooperatively disposed on the supporting rail 14 and includes a first n-shaped frame 61. Two left wheels 62 are disposed on the left inner side of the first n-shaped frame. Two right wheels 63 are disposed on the right inner side of the first n-shaped frame 61. The two left wheels 62 and the two right wheels 63 are respectively matched with the guide grooves 141 in the two sides of the supporting rail 14.

[0026] A third n-shaped frame 42 is fixedly arranged on the middle lower portion of the rotary rod 4 and hinged to one end of the supporting rod 5. A first limiting post 421 is disposed on the third n-shaped frame 42 and used to limit the clockwise rotation angle of the supporting rod 5.

[0027] Two protrusions 64 respectively extend out from two sides of the upper portion of the first n-shaped frame 61 and are hinged to the other end of the supporting rod 5 through a hinge pin 65.

[0028] A left cross rod 7 and a right cross rod 71 respectively extend out from two sides of the middle of supporting rod 5. A left pull rod 8 and a right pull rod 81 are respectively hinged to the end of the left cross rod 7 and the end of the right cross rod 71. Elastic ropes 9 are respectively disposed between the left pull rod 8 and the rotary rod 4 as well as between the right pull rod 81 and the rotary rod 4.

[0029] A first suspension pin 43 is arranged on the lower portion of the rotary rod 4. Second suspension pins 10 are respectively arranged in the middle of the left pull rod 8 and the middle of the right pull rod 81. The elastic ropes 9 are suspended between the second suspension pins 10 and the first suspension pin 43. Hooking wheels 101 are disposed on the second suspension pins 10. One ends of the elastic ropes 9 are wound on the hooking wheels 101, and the other ends of the two elastic ropes 9 are connected together and hooked on the first suspension pin 43.

[0030] A left limiting part 8a is fixedly arranged on the outer surface of an end, close to the left cross rod 7, of the left pull rod 8. When touching the left cross rod 7, the left limiting part 8a restrains the left pull rod 8 from continuing to rotate towards the rotary rod 4. A right limiting part 81a is fixedly arranged on the outer surface of an end, close to the right cross rod 71, of the right pull rod 81. When touching the right cross rod 71, the right limiting part 81a restrains the right pull rod 81 from continuing to rotate towards the rotary rod 4. In this way, the left pull rod 8 and the right pull rod 81 will not deflect towards one side during exercise.

[0031] A second limiting post 44 is arranged on the rear lower portion of the rotary rod 4 and matched with the supporting rod 5 to limit the descent height of the free end of the rotary rod 4. A counter 20 is arranged on the upper side of the front end of the rotary rod 4.

[0032] The supporting rod 5 includes a front supporting rod section 51 and a rear supporting rod section 52. The front supporting rod section 51 is sleeved with the rear supporting rod section 52, which is provided with a plurality of positioning holes at intervals. An adjusting bolt 53 penetrates through the side face of the front supporting rod section 51 to be selectively matched with one positioning hole on the rear supporting rod section 52. In this way, the length of the supporting rod 5 can be changed, and the pulling force to the left pull rod 8 and the right pull rod 81 can also be changed.

[0033] When the exercise machine in this embodiment is used, the user sits on the cushion 2 to make boating motions by stepping on the left pedal 3 and the right pedal 31 with both feet and by holding the left pull rod 8 and the right pull rod 81 with both hands. Under the combined effect of a pulling force and the weight of the user, the supporting rod 5 and the rotary rod 4 rotate back and forth, so that the human body also moves upwards, downwards, forwards and backwards while making boating motions, and thus, both a boating exercise effect and a riding exercise effect are achieved.

[0034] The above embodiment is only a preferred embodiment of the invention. All equivalent transformations made by those skilled in this field based on the Claims should fall within the protection scope of the invention.
