Tennis racquet with striker head

摘要

The racquet comprises a tension frame for strings (4), and a grip shaft (6) standing away from the striker head with a grip (7) and at least one spring-mass system (10). The spring-mass system lies on one side of a central plane vertical to the plane of the strings and enclosing the longitudinal axis of the grip shaft. There is a mass which can move along a channel (11') extending from the grip into the striker head (2). The mass can move, against the effect of a return spring, between the starting position in the grip and an end position in the striker head. The mass comprises several bodies connected to each other in the manner of a string of pearls. Its movement channel is formed from the channel of an outer hose (11).
