  This utility certificate relates to a portable exerciser, and more particularly to a portable exerciser that provides two modes of operation to implement an exercise.

  In working life, many people have few opportunities to exercise outdoors. Therefore, many exercisers are marketed, such as treadmill, bike, chest expander, and so on.

  However, most exercisers are bulky and heavy so that conventional exercisers are difficult to move. Therefore, the field of use of conventional exercisers is limited.

The second rotor includes a centrally and longitudinally delimited through opening for pivotally receiving the second shaft and a second stop extending longitudinally from the second rotor toward the body. The second rotor abuts against the second projecting portion of the body to prevent the second rotor from being excessively rotated. A second torsion spring is fitted on the second shaft between the body and the second rotor. The second torsion spring has a first end inserted into the body and a second end inserted into the second rotor to provide a restitution force to the second rotor.

A second stop 44 extends longitudinally from the second rotor 40 near the periphery thereof to the body 10 and laterally into abutting contact with the second projection 14 and the second body side 10, as shown in Figures 2 and 9A, to prevent the second rotor 40 from being rotated in excess. There is a series of holes 45 in the first face of the second rotor 40 corresponding to the second bore 12 in the body 10. A second torsion spring 47 is mounted around the second shaft 17. The second torsion spring 47 has a first end of insertion 470 and a second insertion end 471 formed respectively at the two opposite ends thereof. The first and second insertion ends 470 and 471 are respectively inserted into the second drilling hole 12 and into a corresponding hole in the series of bores 45 to adjust the original torsion of the second torsion spring 47.

The coupler 50 has a series of teeth 53 extending longitudinally to from one side of the coupler 50 and which engage selectively in the series of teeth 46 of the second rotor 40. In a normal state, the series of teeth 53 of the coupler 50 is disengaged from the s a series of teeth 46 of the second rotor 40 due to the return of force of the spring 55 between the second rotor 40 and the coupler. The coupler 50 has a plurality of radial perforations 54 made in the outer periphery of the coupler 50.

  The stent 60 is integral with the coupler 50. The stent 60 includes a hollow seat 61 provided to receive the coupler 50 and the second rotor 40 and to partially receive the body 10. The hollow seat 61 of the stent 60 comprises a closed end 2863896 8 opposite the body 10. A through bore 62 exists in the center of the closed end of the hollow seat 61 to allow the insertion end 18 of the second shaft 17 to extend through the seat Hollow 61 of the stent 60. The hollow seat 61 of the stent 60 has a plurality of radial bores 63 in its outer periphery and extending through the hollow seat 31. Each of the bores 63 in the hollow seat 61 of the stent 60 is in alignment with a corresponding bore 54 of the plurality of holes of the coupler 50, causing a locking piece (not referenced) to extend through the bore 63 and is secured in the bore 54 correspondent of the Coupler 50 for securing the hollow seat 61 of the stent 60 on the coupler 50.

  To simplify the structure of the elongation device 60, the coupler 50 can be made in one piece with the hollow seat 61. The hollow seat 61 has a skirt 64 extending longitudinally towards the body 10 and received to move between the lip 34 of the hollow seat 31 of the torsion wrench 30 and the body 10 to prevent the entry of foreign matter into the portable exerciser according to the present utility model.

  A lever 70 is pivotally mounted at the free end of the insert end 18 of the second shaft 17 to drive the hollow seat 61 of the stent 60 and the coupler 50 and thereby engage the coupler 50 with the second rotor 40 after the insertion end 18 has come to extend through the coupler 50 and the hollow seat 61 of the expander 60. The lever 70 has two cams 71 extending outwards and corresponding to the two flats 19 on the outside. free end of the portion of the insertion end 18 of the second shaft 17. Each cam 71 has a pivot bore 72 corresponding to each other to allow a rod 73 to extend between the two cams 71 and the pivot drilling 72 or 190 in the insertion end 18. The two cams 71 are provided to abut against the closed end of the hollow seat 61 of the elongation device 60 for the displacement of the coupler 50 in view of its engagement with the second rotor 40.

  With reference to FIGS. 2, 4, 6, 7 and 7A, during a twisting exercise, the extension device is limited by the integral nature of the coupler 50 with the hollow seat 61 and is engaged with the second rotor 40 by the effect of the cam 71 of the lever 70. In addition, the second stop 44 comes into abutting contact with the second projection 14 of the body 10. As a result, the user can maneuver the first handle 35 towards the second sleeve 65 to twist the first torsion spring 26 to achieve an exercise effect and the first stick 35 will return back to its original position after stopping the operation of the first stick 35 due to the return of force of the first torsion spring 26.

  Referring to FIGS. 2, 4, 8, 9 and 9B, the first stick 35 is limited to a displacement in the opposite direction of movement of the second stick 65 due to the first stop 25 which comes into abutting contact with the first projection 13 and the first rotor 20 is received in solidarity in the hollow seat 31 of the torsion key device 30. As a result, the user can extend the second handle 65 opposite the first handle 35 to twist the second torsion spring 47 so as to to effect an exercise effect and the second leg 65 will move back to its original position after expansion due to force restitution of the second torsion spring 47.

  Referring to FIGS. 4 and 5, by adjusting the angle between the first handle 35 and the second handle 65 and the travel distance of the exerciser of the present utility model, the lever 70 is operated to separate the two cams 71 of the closed end of the seat 61 of the extension device 60. The coupler 50 is disengaged from the second rotor 40 by the effect of restoring the force of the spring 55 and the stent 60 is in a free state relative to The lever 70 is again operable to abut the two cams 71 against the closed end of the hollow seat 61 of the stent 60 to urge the coupler 50 to move toward the second rotor. 40 and engage with the second rotor 40 when the angle between the first handle 35 and the second handle 65 is set to a predetermined degree.

  As described above, the exerciser according to the present utility model is portable so that the user can conveniently practice in any location. In addition, the portable exerciser of this utility model has two modes of operation for the user to train his hands or legs by developing an exercise effect.
