TENNIS SIMULATOR DESIGNED TO IMPROVE THE FIRST AND SECOND SERVES WHEN PLAYING LAWN TENNIS Russian patent published in 2022 - IPC A63B1/00 

FIELD: sport.

SUBSTANCE: tennis simulator is designed to improve the first and second serves when playing lawn tennis. A rack (4) consisting of a support pipe (2) and a sliding pipe (3) is mounted on a metal base (1). The rack (4) is reinforced with vibration stabilizers (11). The shock-return mechanism (15) is mounted at the upper end of the sliding pipe (3) and contains a lever holder (23) with a return spring (14) installed inside, connected to a lever (9) bearing a shock surface (5). The impact surface (5) due to the horizontal part (9a) of the bearing lever (9) is removed and is located at a distance of at least 15 cm to the right of the rack (4) for a right-handed player and to the left for a left-handed player. Using a sliding pipe (3) and a clamp (13), the impact surface (5) is installed in the center of the rim (101) of the racket (100) in accordance with the height of the player (500) kneeling on the stand (12) with his arm extended over his head with the racket (100). The weight of the racket used (100) has been increased from 50 to 300 g with 25 g and 50 g weights (103a or 103b) in accordance with the physical development of the player. The weights are fixed symmetrically on the rim or in the opening below the rim (101). When the player strikes with a weighted racket on the impact surface (5), the bearing lever (9) flies horizontally along the vertical axis of rotation (200) to a fixed stop and under the influence of a spring (14), which initially counteracts rotation, the bearing lever returns to its original position, delivering the impact surface (5): a ball (10) or a pad (10a) to receive the next blow.

EFFECT: expansion of the range of training equipment.
