1. Field of the Invention
The present invention relates to an exercising device and, more particularly, to a gyration type exercising device.
2. Description of the Related Art
A conventional exercising device comprises a housing 50, a front rotation mechanism 60 mounted on the front side of the housing 50, a rear rotation mechanism 70 mounted on the rear side of the housing 50, a gear unit 52 mounted in the housing 50 and connected with the front rotation mechanism 60 and the rear rotation mechanism 70 to control movement of the front rotation mechanism 60 and the rear rotation mechanism 70, and a drive motor 51 mounted in the housing 50 and connected with the gear unit 52 to drive the gear unit 52. The front side of the housing 50 is provided with a mounting tube 53. The front rotation mechanism 60 includes a rotation upright 61 rotatably mounted in the mounting tube 53 and rotated by the gear unit 52, a retractable bar 62 mounted on the upper end of the rotation upright 61, a connecting rod 63 rotatably mounted on the retractable bar 62, and a T-shaped handle 64 having a first end mounted on the connecting rod 63 and a second end provided with a grip 641. The rear rotation mechanism 70 includes a rotation post 71 rotatably mounted in the housing 50 and rotated by the gear unit 52, an elbow 711 mounted on the upper end of the rotation post 71, a transverse bar 72 mounted on the elbow 711, a roller 74 rotatably mounted on the bottom of the transverse bar 72 and movable on the top of the housing 50, and a rotation disk 73 rotatably mounted on the top of the transverse bar 72. When in use, a user is placed on the exercising device with his feet treading the rotation disk 73 and with his hands holding the grip 641. Thus, when the gear unit 52 is driven by the drive motor 51, the front rotation mechanism 60 and the rear rotation mechanism 70 are rotated by the gear unit 52 simultaneously to swivel the user's body so as to achieve an exercising effect. However, the user is moved by operation of the drive motor 51 so that the user does not move his body by himself, thereby decreasing the exercising effect of the exercising device.
In accordance with the present invention, there is provided a exercising device, comprising a gyration unit, a damper mounted on the gyration unit and a drive handle connected with the gyration unit. The gyration unit includes a mounting frame and a rotation wheel rotatably mounted on the mounting frame and driven by operation of the drive handle. The rotation wheel of the gyration unit is provided with a rotation shaft which is rotatably mounted on the mounting frame. The damper is mounted on the mounting frame of the gyration unit and has a side pressing a periphery of the rotation wheel to provide a damping force to the rotation wheel of the gyration unit.
The primary objective of the present invention is to provide a gyration type exercising device that can exercise a user's body completely.
According to the primary advantage of the present invention, when the user's two hands hold the holding bar to move the drive handle in a gyration manner, the user's body has to move forward and backward in a reciprocal manner and has to exert a force on the drive handle successively to rotate the rotation wheel reciprocally so as to exercise the user's body completely, thereby enhancing the exercising effect.
According to another advantage of the present invention, the adjusting member is movable on the mounting frame to move the damper relative to the rotation wheel so as to adjust the resistance and damping force of the damper applied on the rotation wheel.
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.
Referring to the drawings and initially to
The gyration unit 10 includes a mounting frame 11 and a rotation wheel 12 rotatably mounted on the mounting frame 11 and driven by operation of the drive handle 30. The rotation wheel 12 of the gyration unit 10 is provided with a rotation shaft 121 which is rotatably mounted on the mounting frame 11. The rotation shaft 121 is secured on and located at a central portion of the rotation wheel 12 so that the rotation wheel 12 is rotatable about the rotation shaft 121.
The damper 20 is mounted on the mounting frame 11 of the gyration unit 10 and has a side pressing a periphery of the rotation wheel 12 to provide a damping force to the rotation wheel 12 of the gyration unit 10. The damper 20 provides a damping force to the rotation wheel 12 of the gyration unit 10 in a frictional, magnetically attractive or generator manner.
The gyration type exercising device further comprises a tension adjusting member 21 mounted on the mounting frame 11 of the gyration unit 10 and connected with the damper 20 to move the damper 20 relative to the rotation wheel 12 of the gyration unit 10 so as to adjust the damping force of the damper 20 applied on the rotation wheel 12 of the gyration unit 10.
The drive handle 30 is pivotally connected with the rotation wheel 12 of the gyration unit 10. The drive handle 30 has a first end pivotally connected with the rotation wheel 12 of the gyration unit 10 and a second end provided with a holding bar 31. The first end of the drive handle 30 is arranged eccentrically on the rotation wheel 12 of the gyration unit 10. The holding bar 31 is perpendicular to the drive handle 30.
The gyration type exercising device further comprises a support rack 13 mounted on a bottom of the mounting frame 11 to support the mounting frame 11 of the gyration unit 10, and a tread cushion 131 mounted on a side of the support rack 13.

The transmission mechanism 40 includes a drive member 42 rotatably mounted on the mounting frame 11 of the gyration unit 10 and a transmission member 41 mounted between the drive member 42 and the driven member 122 of the gyration unit 10 to transmit a power of the drive member 42 to the driven member 122 of the gyration unit 10. Preferably, the drive member 42 of the transmission mechanism 40 is a drive wheel and has a diameter greater than that of the driven member 122 of the gyration unit 10. In addition, the transmission member 41 of the transmission mechanism 40 is a belt.
The drive handle 30 is pivotally connected with the transmission mechanism 40. The drive handle 30 has a first end pivotally connected with the drive member 42 of the transmission mechanism 40 and a second end provided with a holding bar 31. The first end of the drive handle 30 is arranged eccentrically on the drive member 42 of the transmission mechanism 40.

Accordingly, when the user's two hands hold the holding bar 31 to move the drive handle 30 in a gyration manner, the user's body has to move forward and backward in a reciprocal manner and has to exert a force on the drive handle 30 successively to rotate the rotation wheel 12 reciprocally so as to exercise the user's body completely, thereby enhancing the exercising effect. In addition, the adjusting member 21 is movable on the mounting frame 11 to move the damper 20 relative to the rotation wheel 12 so as to adjust the resistance and damping force of the damper 20 applied on the rotation wheel 12.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
