Abstract
The current invention aims at improving the playability, durability, and spin generation of different playing rackets, as tennis, squash, and badminton rackets. The method to do so is by applying mechanical forces which generate relative motion of the latitudinal strings over the longitudinal strings. This is done in order to create friction that generate depressions in the contact points of the latitudinal strings with the longitudinal strings. These depressions, made by the described method and machine, induce more friction, and generate spin, while increasing the playability and durability during the play.
Claims14
A tennis racket spin and durability improving machine comprising:
- a. at least one string holder useful for moving a latitudinal string of a strung racket sideways in the longitudinal strings direction, comprising:
- (i) at least one protrusion (tooth) which can be placed besides a string (ii) a holder frame, said holder frame is interconnected to all said protrusions of the string holder. Said holder frame is interconnected with either the racket holder (b) or the force generating mechanism (c) or both of them (b and c);
- b. a racket holder useful for setting the racket in place, comprising:
- at least one racket frame holder of a general form useful for holding the racket directly. Said racket holder is interconnected to said string holder(s) (a) directly or via a force generating mechanism (c);
- and
- c. at least one force generating mechanism, of a general form, useful for repetitively moving said string holder(s) back and forth in approximately the longitudinal strings axis direction. Said force generating mechanism is interconnected to said string holder(s) (a).
A method of generating depressions on strung sports racket latitudinal strings wherein said method comprising the steps of:
- a. providing a sports racket;
- holding a strung racket in place, approximately in the same position;
- b. applying mechanical forces on at least one latitudinal string in order to rub it back and forth over the longitudinal strings in the contact points;
- and
- c. continuing the process until depressions up to 2 mm in depth are formed at any desired part of the latitudinal strings.
