Abstract
The present invention relates to the construction of sports rackets, such as those used for tennis and similar games. The racket has weight means which moves transverse to the plane of the racket stringing, mounted adjacent to the bow or head of the racket to provide inertial rebound deadening when the racket strikes a ball.
Claims7
A sports racket having a bow portion, a handle attached to said bow portion and means providing a ball striking surface held by said bow portion, said ball striking surface generally defining a plane, a support attached to said racket adjacent the bow portion, and weight means movably retained relative to said support so as to permit substantially unrestrained movement of said weight means in direction transverse to said plane under forces generated during manual swinging of said racket to permit the weight means to physically shift when the sports racket strikes a ball, said weight means being of sufficient mass so that when the weight means shifts it effects a counteracting force reducing rebound of the sports racket after striking a ball.
A sports racket having a bow portion defining a racket plane and having means for striking a sports missile and having a handle attached to said bow portion, said racket being capable of being manually swung in a striking direction to strike a sports missile, a hollow container mounted to the racket adjacent the bow portion and being attached to transmit forces on the container directly to the racket, a quantity of heavy discrete shot like particles partially filling said container and movable in said container without substantial restraint in opposite directions along an axis extending generally along the intended direction of swing of the racket generally perpendicular to the racket plane, said container having end walls generally normal to said axis against which the shot like particles impinge under forces along the axis, the force of said shot like particles hitting an end wall of said container when the racket strikes a sports missile during swinging thereof opposing the rebounding tendency of the racket.
