ABSTRACT:
A handle-equipped bowling ball comprising a spherical ball body provided with a pair of parallel, spaced-apart bores which are symmetrically disposed with respect to the center of the ball. In the surface of the ball there is a channel that extends between the mouths of the bores. A generally U-shaped handle structure is provided, characterized by parallel leg portions which are slidably movable in the bores of the body, and by a yoke portion that extends between and joins the leg portions, said yoke portion being adapted to occupy the channel in the body so as to present a flush exterior surface when the handle structure is retracted. The handle structure can be extended to a point where stops are engaged, to prevent its further pull-out; it is normally held retracted by coil springs disposed on the leg portions. To prevent unintentional extending of the handle structure against the restraining action of the coil springs when the ball is spinning rapidly, the leg portions are provided with counterweights which essentially counterbalance the centrifugal force on the handle structure. Simple abutment collars coact with the coil springs to prevent deformation of the same, and to cradle the springs for minimizing interference therefrom with the free action of the handle structure.
