Portable exercise device

Portable exercise device description/claims

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.
