Abstract

The present invention discloses a multi-handle dumbbell comprising: two counterweights, a central handle and three surrounding handles. The central handle and the three surrounding handles are provided for a user to grip, both ends of the central handle are respectively connected to the centers of the two counterweights, the three surrounding handles are disposed around and parallel to the central handle, each surrounding handle is provided with two ends thereof respectively connected to the two counterweights, and the three surrounding handles are spaced equidistantly from each other. By gripping the central handle, the user can perform weight training with a movement suitable for a conventional dumbbell, and by gripping the surrounding handle, the user can perform weight training with a movement suitable for a conventional kettlebell.

Claims (8)

1 . A multi-handle dumbbell, comprising:

two counterweights of square plates;

a central handle provided for a user to grip, wherein both ends of the central handle are respectively connected to the centers of the two counterweights; and

three surrounding handles provided for the user to grip, wherein the three surrounding handles are disposed around and parallel to the central handle, each surrounding handle is provided with two ends thereof respectively connected to the two counterweights, and the three surrounding handles are spaced equidistantly from each other,

wherein each of the two counterweights is defined with three dividing regions of different shapes divided by three perpendicular bisectors of line segments between each two adjacent surrounding handles of the three surrounding handles, one of the three surrounding handles is closer to the central handle than the other two surrounding handles, and one of the three perpendicular bisectors is longer than the other two perpendicular bisectors, thereby offsetting a moment balance relative to the center of the central handle.

2 . The multi-handle dumbbell of claim 1 , wherein a diameter of the central handle is greater than that of each handle of the three surrounding handles.

3 . The multi-handle dumbbell of claim 1 , wherein the central handle has a gripping portion and two connecting portions respectively provided at two end parts of the gripping portion, and a diameter of the gripping portion of the central handle gradually decreases from a middle part of the gripping portion to the two end parts of the gripping portion.

4 . The multi-handle dumbbell of claim 1 , wherein each handle of the three surrounding handles has a gripping portion and two connecting portions respectively provided at two end parts of the gripping portion, and a diameter of the gripping portion of each handle of the three surrounding handles gradually decreases from a middle part of the gripping portion to the two end parts of the gripping portion.
