The present invention relates to a portable exercise device, and more particularly to portable exercise device that provides two operating ways for promoting exercise effect.
In a busy life, many people have little opportunity to take an exercise outdoors. Consequently, various exercise devices are marketed, such as treadmill, bike, chest expander, and so on.
However, most of the various exercise devices have a bulky volume are heavy so that the conventional exercise devices are hardly moved. Consequently, the using scope of the conventional exercise devices is limited.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional exercise devices.
The main objective of the present invention is to provide an improved portable exercise device that provides two exercise ways.
To achieve the objective, the portable exercise device in accordance with the present invention comprises a body including a first protrusion laterally extending from a first side of the body and a second protrusion laterally extending from a second side of the body. A first shaft centrally longitudinally extends from the first side of the body and a second shaft centrally longitudinally extends from the second side of the body.
A first rotor is pivotally mounted around the first shaft. The first rotor includes a through hole centrally defined therein for allowing the first shaft extending through the first rotor. A first stopper longitudinally extends from the first rotor. The first stopper has one side abutting the first protrusion to prevent the first rotor from overly rotated. A first torsion spring is sleeved on the first shaft between the body and the first rotor. The first torsion has a first end inserted into the body and a second end inserted into the first rotor to provide a restitution force to the first rotor.
A washer is longitudinally secured on a free end of the first shaft. The washer has a diameter greater than that of the through hole in the first rotor to prevent the first rotor from detaching from the first shaft.
A wrench device is securely mounted to the first rotor. The wrench device includes a hollow seat receiving the first rotor and partially pivotally receiving the body. A first arm extends from an outer periphery of the hollow seat for user to devote himself/herself to a wrench exercise for his/her extremities.
A second rotor is pivotally mounted around the second shaft. The second rotor includes a through hole longitudinally centrally defined therein for pivotally receiving the second shaft and a second stopper longitudinally extending from the second rotor toward the body. The second rotor abuts against the second protrusion of the body to prevent the second rotor from overly rotated. A second torsion spring is sleeved on the second shaft between the body and the second rotor. The second torsion has a first end inserted into the body and a second inserted into the second rotor to provide a restitution force to the second rotor.
A stretch device is pivotally mounted to the second rotor and selectively synchronously moved with the second rotor. The stretch second includes a hollow seat receiving the second and partially pivotally receiving the body. A second arm extends from an outer periphery of the hollow seat of the stretch device for to devote himself/herself to a wrench exercise for his/her extremities.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

The first rotor 20 has a first side opposite to the body 10 and having multiple first bores 22 longitudinally defined in the first side of the first rotor 20 near a periphery of the first rotor 20. A series of second bores 23 defined in a second side of the first rotor 20 and a first stopper 25 longitudinally extending from the second side of the first rotor 20. Further with
The wrench assembly 30 includes a hollow seat 31 securely mounted around the first rotor 20 and is pivotal relative to the body 10. The first rotor 20 can be integrally form with the hollow seat 31. The hollow seat 31 includes a closed end having multiple through holes 33 each aligning with a corresponding one of the multiple first bores 22 and a through hole 32 centrally defined in the close end of the hollow seat 31 for user to easily assemble the bolt and the washer 27. A bolt (not numbered) extends through the through hole 33 and screwed into the corresponding bore 22 in the first rotor 20 to hold the hollow seat 31 in place. The hollow seat 31 has an annular lip 34 longitudinally extending therefrom and corresponding to the body 10. A first arm 35 extends from an outer periphery of the hollow seat 31 for user to devote himself/herself to a wrench exercise for his/her hands or legs. However, the first arm 35 and the hollow seat 31 can be integrally formed. An end piece 38 laterally attached to closed end of the hollow seat 31 for protecting the washer 27 and providing goodlooks.
The second rotor 40 includes a through hole 41 longitudinally centrally defined therein for pivotally receiving the insert section 18 of the second shaft 17. The through hole 41 has an enlarged section 43 formed on one end of the through hole 41 in the second rotor 40 opposite to the body 10. A second stopper 44 longitudinally extends from the second rotor 40 neat a periphery of the second rotor 40 toward the body 10 and laterally abuts against the second protrusion 14 and the second side of the body 10, as shown in
An engager 50 is pivotally mounted to the insert section 18 of the second shaft 17 and selectively engaged to the second rotor 40. The engager 50 includes a through hole 51 centrally longitudinally defined therein for pivotally receiving the insert section 18. The through hole 51 in the engager 50 has an enlarged section 52 formed to co-axially correspond to the enlarged section 43 of the through hole 41 in the second rotor 40 so that a spring 55 is compressively received in the enlarged section 43 of the through hole 41 in the second rotor 40 and the enlarged section 52 of the through hole 51 in the engager 50. The engager 50 has a series of tooth 53 longitudinally extending from one side of the engager 50 and selectively engaged to the series of tooth 46 of the second rotor 40. In a normal state, the series of tooth 53 of the engager 50 is disengaged from the series of tooth 46 of the second rotor 40 due to a restitution force of the spring 55 between the second rotor 40 and the engager. The engager 50 has multiple holes 54 radially defined in an outer periphery of the engager 50.
The stretch device 60 is secured on the engager 50. The stretch device 60 includes a hollow seat 61 provided to receive the engager 50 and the second rotor 40, and partially receive the body 10.
