Abstract A tethered ball tennis practice device having a support arm pivotally attached at one of its ends to a vertical support surface whereby the arm will pivot in a horizontal plane. A tennis ball has an elastic cord extending diametrically therethrough. One end of the elastic cord is attached to the support arm at the end which is remote from the vertical support surface. The other end of the elastic cord is attached to the vertical support surface at a point below the support arm. The arm may be locked in an extended position which is substantially perpendicular to the support wall. In the extended position, the tennis ball is suspended for tennis practice. When the arm is pivoted to a stored position the arm, ball and the tether lie substantially against the vertical wall. The device may also be locked in the stored position.
A captive ball apparatus comprising: a ball, an elastic cord passing through said ball, said ball being adjustable along said cord, a vertical support wall for supporting said cord and said ball, support means, said support means comprising a plate means and an elongated arm means, said arm means having one of its ends pivotally connected to said plate means and said plate means being attached to said vertical support wall such that said arm will pivotally swing in a substantially horizontal plane and whereby said arm will be capable of assuming substantially parallel and perpendicular positions relative to said wall, said elastic cord having one of its ends attached to said wall at a point below said plate means and its other end being attached to said arm at a point remote from said plate means such that said ball will be positioned between said attachment points, the length of said elastic cord being substantially the same when said arm is in said perpendicular and parallel positions, and means for locking said arm in said parallel and perpendicular positions.
