Abstract

The tennis practice aid comprises a ball fixed to the end of an arm hinging in a vertical plane, and mounted on a base. At the level of the hinge point (6) of the arm (5), a device is provided to sustain oscillations of the ball through nearly 90 deg. to either side of the summit of its trajectory, or to halt it at the latter within a specified time. Coil springs acting in opposition can be used to sustain the oscillations, while the ball can be halted by a single-acting hydraulic damper (12) acting in opposition to the springs (10). The base can have a hinge (14) to allow folding for transport.
