Demountable practice device attachable to the strings of a stringed racquet

A device for practicing racquet swings by striking a tethered ball, comprising:

• a racquet having a head including a pair of opposite faces formed by spaced apart tensioned strings defining openings;
• a flexural anchor means comprising a segmented cylinder having a pair of substantially straight, spaced side edges and a pair of curved edges, and wherein said anchor means is positioned and retained on one face of the racquet head solely by edge means projecting from said straight, spaced apart side edges and engaging the tensioned strings;
• said elastic tether, sized to be received through an openings defined by said tensioned strings, and having first and seconds ends, said elastic tether being positioned in a string opening with said first end being attached to said anchor means and said second end being attached to a ball so that the striking of said ball with the opposite face of the racquet head face generates potential energies in both the racquet strings and anchor means.

In the combination of a conventional stringed racquet and a demountable practice device including an electric tether, a tethered ball, and means for anchoring the elastic tether to the strings of said racquet, the improvement wherein said tether passes through an opening provided between the strings of said racquet, said means for anchoring the elastic tether comprises a flexural body having a pair of spaced side edges, each side edge engaging certain of said strings and movably retained thereon so that tensioning in said elastic tether caused by the struck ball at the outermost extent of ball travel causes flexure of both said body and said strings whereby potential energy is stored therein.
