摘要

A children's tennis racket as an abridged version (K1) or short version (K2) or a junior version (K3), comprising a frame (1) defining a bed of springs (3), strings and a handle (K2) and whose point of balance (S) is essentially distanced in the longitudinal axis of the racket from the end of the handle. In the lightweight version, said racket has a point of balance (S) which, when measured from the end of the handle, is located at approximately 1.0 cm maximum inside the inner surface of the frame (F1,F2 or F3). The invention relates to a system enabling children to learn how to play tennis, comprising transversal markings (M) which can be offset at a distance from the net (8) on a standard playing field (6) and at least one tennis racket for children (K1,K2,K3) which is provided with strings, having a maximum weight of 18°g and whose point of balance (S) is located at a maximum of 1.0 cms inside the frame.
