[0020]As shown in FIG. 1, a rotary dumbbell 100 of the preferred embodiment of the present invention includes a handle 10, on opposite ends of which two wheels 30 and two weight devices 40 are pivoted.

[0021]As shown in FIG. 2, the handle 10 is a tubular member with an axle 12 passing there through. Two bearings 11, only one of which is shown in FIG. 2, are mounted in the opposite ends of the handle 10 to support the axle 12 that the axle 12 may rotate freely relative to the handle 10. The axle 12 has two connecting portions 14 at opposite ends, each of which has two flat surfaces 15. The connecting portions 14 of the axle 12 extend out of the handle 10 to connect the wheels 30 and the weight devices 40. In other words, the wheels 30 and the weight devices 40 have the same rotation axis which is the axle 12.

[0022]Two pairs of first covers 20 and second covers 50 are respectively fitted to the opposite ends of the axle 12 in sequence. Between each pair of the first cover 20 and the se...

Abstract

A rotary dumbbell of the present invention includes a handle, and two pairs of wheels and weight devices pivoted on opposite ends of the handle for rotation. Each of the wheels has a center pivoted on the handle and is unadjustable in a radial direction thereof that the wheels centrally rotate. Each of the weight devices is adjustable in a radial direction thereof that the weight devices may eccentrically rotate. The dumbbell further includes two pairs of covers to hold the weight devices and the wheels respectively. Therefore, user may get an extra loading because of the eccentric rotation of the weight devices when he/she shakes the dumbbell. The dumbbell may be used as a roller to train abdominal muscles while the wheels serve the function of rollers.
