DETAILED DESCRIPTION OF THE INVENTION

[0022] Referring to the drawings and initially to FIGS. 1 and 2, an exercising device in accordance with a preferred embodiment of the present invention comprises a seat frame 10, an oscillation frame 20, a first resistance device 30, a support frame 40, a chest pull mechanism 50, and a second resistance device 60.

[0023] The seat frame 10 is provided with a seat cushion 11. An oblique support leg 12 is mounted on a bottom of the seat frame for supporting the seat frame 10. The seat frame 10 has a first end provided with a pivot ear 13 extending upward in an inclined manner.

[0024] The oscillation frame 20 has a first end formed with a bent hollow tube provided with a knob 21. A substantially U-shaped force output frame 23 is selectively mounted on the first end of the oscillation frame 20, and is a bottom side provided with a combination portion 231 extended into the first end of the oscillation frame 20 and retained by the knob 21. The substantially U-shaped force output frame 23 has two distal ends each provided with a handle 232. The first end of the oscillation frame 20 is pivotally mounted on the pivot ear 13 of the seat frame 10, so that the oscillation frame 20 may be pivoted and oscillated relative to the seat frame 10. The oscillation frame 20 has a substantially U-shaped second end provided with two spaced soft pads 22.

[0025] The first resistance device 30 includes a pivot lever 31, a connecting lever 32, a first damping cylinder 33, and a second damping cylinder 34.

[0026] The pivot lever 31 has a first end pivotally mounted on a mediate section of the bottom of the seat frame 10. The connecting lever 32 has a first end pivotally mounted on a second end of the pivot lever 31, and a second end pivotally mounted on a mediate portion of the oscillation frame 20. The first damping cylinder 33 has a first end pivotally mounted on a first side of a mediate portion of the pivot lever 31, and a second end pivotally mounted on a bottom of a second end of the seat frame 10. The second damping cylinder 34 has a first end pivotally mounted on a second side of the mediate portion of the pivot lever 31 to align with the first damping cylinder 33, and a second end pivotally mounted on a bottom of the first end of the seat frame 10.

[0027] The support frame 40 is mounted on the second end of the seat frame 10, and may be detached and separated from the second end of the seat frame 10 according to the user's requirement. The support frame 40 includes an upright stand 41 which has a first side provided with a cushion 42, and a second side having an upper end provided with a pivot ear 44, a mediate portion provided with a pivot ear 43, and a lower end provided with a pivot ear 45.

[0028] The chest pull mechanism 50 is mounted on a top of the upright stand 41. The chest pull mechanism 50 is a conventional structure, and will not be further described in detail.

[0029] The second resistance device 60 includes a pivot lever 61, two resistance swing arms 62, a third damping cylinder 63, and a fourth damping cylinder 64.

[0030] The pivot lever 61 of the second resistance device 60 has a first end pivotally mounted on the pivot ear 43 of the mediate portion of the upright stand 41. Each of the two resistance swing arms 62 is pivotally mounted on the first end of the pivot lever 61 of the second resistance device 60. The third damping cylinder 63 has a first end pivotally mounted on a top face of a second end of the pivot lever 61, and a second end pivotally mounted on the pivot ear 44 of the upper end of the upright stand 41. The fourth damping cylinder 64 has a first end pivotally mounted on a bottom face of the second end of the pivot lever 61, and a second end pivotally mounted on the pivot ear 45 of the lower end of the upright stand 41.

[0031] In operation, referring to FIGS. 2 and 3 with reference to FIG. 1, the user may press or pull the force output frame 23 or the oscillation frame 20, thereby obtaining a body exercising effect.

[0032] When the oscillation frame 20 is pulled or the force output frame 23 is pressed, the oscillation frame 20 may be pivoted on the pivot ear 13 of the seat frame 10 to move from the position as shown in FIG. 2 to the position as shown in FIG. 3, to pivot and move the connecting lever 32 which pivots and moves the pivot lever 31 which pulls the first damping cylinder 33 and pushes the second damping cylinder 34, so that the first damping cylinder 33 and the second damping cylinder 34 may produce a damping effect to be applied on the user, thereby obtaining a body exercising effect.

[0033] Thus, the oscillation frame 20 may be used to exercise the user's legs, and the force output frame 23 may be used to exercise the user's arms.

[0034] In addition, referring to FIGS. 2 and 4 with reference to FIG. 1, the user may use the second resistance device 60, and the two resistance swing arms 62 of the second resistance device 60 may be pulled upward and pushes downward, thereby obtaining a body exercising effect.

[0035] When the two resistance swing arms 62 of the second resistance device 60 are pulled upward to move from the position as shown in FIG. 2 to the position as shown in FIG. 3, the pivot lever 61 may be pivoted on the pivot ear 43 to move and deflect downward, thereby pulling the third damping cylinder 63 and pushing the fourth damping cylinder 64, so that the third damping cylinder 63 and the fourth damping cylinder 64 may produce a damping effect to be applied on the user, thereby obtaining a body exercising effect.

[0036] Accordingly, the exercising device in accordance with the present invention has the following advantages.

[0037] 1. When the oscillation frame or the force output frame is lifted and pressed, the oscillation frame may be pivoted relative to the seat frame, to pivot and move the connecting lever which pivots and moves the pivot lever which pulls the first damping cylinder and pushes the second damping cylinder, so that the first damping cylinder and the second damping cylinder may produce a damping effect to be applied on the user, thereby obtaining a body exercising effect. Thus, the user may obtain a resistance effect when the oscillation frame or the force output frame is lifted and pressed, thereby obtaining a body exercising effect during the reciprocal stroke of the oscillation frame or the force output frame.

[0038] 2. When the two resistance swing arms of the second resistance device are pulled upward and pushed downward, the pivot lever may be pivoted on the pivot ear to move and deflect downward, thereby pulling the third damping cylinder and pushing the fourth damping cylinder, so that the third damping cylinder and the fourth damping cylinder may produce a damping effect to be applied on the user, thereby obtaining a body exercising effect. Thus, the user may obtain a resistance effect when the two resistance swing arms of the second resistance device are pulled upward and pushed downward, thereby obtaining a body exercising effect during the reciprocal stroke of the two resistance swing arms of the second resistance device.

[0039] 3. Each of the first resistance device and the second resistance device has two damping cylinders to provide a balance effect, thereby preventing from producing noise and hit during operation.

[0040] While the preferred embodiment of the present invention has been shown and described, it will be apparent to those skilled in the art that various modifications may be made in the embodiment without departing from the spirit of the present invention. Such modifications are all within the scope of the present invention.
