Abstract
A device for practicing tennis strokes that enables a user to develop a correct reflex action and a proper stance while playing tennis, including at least: a supporting structure (1) having a base (1a); an arm (3) having a work trajectory; a torsion member (2) including a subunit (12) for adjusting a force acting on the arm (3) and dynamics of movement of the arm (3); a subunit (6) for adjusting the height of the arm; a subunit (8) for setting a deflection of the work trajectory of the arm; a subunit (9) for adjusting the angle of inclination of the torsion member to the vertical axis (B); and a clamping member (4) for non-invasively clamping a tennis ball (5).

A device for practicing tennis strokes, comprising:
- a supporting structure (1) having a base (1a);
- an arm (3) having a work trajectory;
- a torsion member (2) comprising a subunit (12) for adjusting a force acting on the arm (3) and dynamics of movement of the arm (3);
- a subunit (6) for adjusting the height of the arm;
- a subunit (8) for setting a deflection of the work trajectory of the arm;
- a subunit (9) for adjusting the angle of inclination of the torsion member to the vertical axis (B);
- and
- a clamping member (4) for non-invasively clamping a tennis ball (5);
- wherein
- said arm (3) comprises an element having a high elasticity;
- an end (3b) of said arm (3) lying opposite the ball (5) is fastened to said supporting structure (1) via said torsion member (2);
- and
- a connection (13) between said subunit (6) for adjusting the height of the arm, said subunit (8) for setting a deflection of the work trajectory of the arm, and said subunit (9) for adjusting the angle of inclination of the torsion member to the vertical axis (B), lies between a surface area (A) defined by said base (1a) of said supporting structure (1) and said end (3b) of said arm (3) lying opposite the ball (5).
