Patent ID: 7326158

Claim:
A ball exerciser comprising: a deformable rolling body defining a rolling axis in a longitudinal direction, and having an outer surrounding wall surface which surrounds the rolling axis, and which includes uppermost and lowermost areas that are opposite to each other relative to the rolling axis, and that extend angularly about a center point in the rolling axis and in the longitudinal direction to respectively terminate at first upper and lower lateral borderlines, and a first lateral mount wall which extends in a direction transverse to the rolling axis to interconnect said first upper and lower lateral borderlines; a first stationary coupling member which is made from a material more rigid than that of said rolling body, and which is secured to said first lateral mount wall, said first stationary coupling member having a first stationary coupling end which is distal from said first lateral mount wall; a first movable coupling member having a first movable coupling end which is disposed to be swivelable and frictionally rotatable relative to said first stationary coupling end about the rolling axis; and a first grip including a first grip segment which is disposed to be spaced apart from said first lateral mount wall along the rolling axis, and which extends angularly about the center point and in the transverse direction to terminate at upper and lower first anchoring ends that are respectively disposed adjacent to said first upper and lower lateral borderlines, and that are coupled to said first movable coupling end so as to permit said first grip segment to be swiveling with said first movable coupling member.
