Abstract
A training device which interactively guides a tennis racquet by exerting a towing force on a card which is connected to the tennis racquet. The device includes a vertically adjustable support connected with a guide pole fixed to a wall. A swivel arm is movably supported on the support and has a distal end which suspends a ball therefrom. The cord extends along the swivel arm and the support, and one end thereof is connected to the racquet through a stirrup.
Claims21
A training device for learning to guide a tennis racquet comprising a cord having one end connected to the tennis racquet and said cord being fed through a plurality of pulleys;
- and a plurality of mechanisms which are adjustably mounted on a support to control exertion of a towing force on the cord so as to interactively guide and control the racquet during at least one phase of a swing during execution of a stroke, wherein one of said mechanisms comprises a swivel arm on one end of which at least one of the pulleys is fixed above and in front of the head of a player during serve training, and the swivel arm is automatically arrested in an upper at-rest position by means of an arresting mechanism located on the support.
A training device for learning to guide a tennis racquet or other sporting equipment comprising a cord in which one end is connected to the tennis racquet and said cord is fed through a plurality of pulleys;
- and a plurality of mechanisms which are adjustably mounted on a support to control exertion of a towing force on the cord during at least one phase of a swing during execution of a stroke, wherein the towing force on the cord is provided by means of an elastic rope connected with a movable releasing device for setting the cord free at a defined point of the swing, wherein the movable releasing device includes an offset hinged folding bracket with a stub axle for one of the pulleys which is fixed in a working position by means of a releasing mechanism for setting the bracket free at the defined point of the swing.
A training device for learning to guide interactively a tennis racquet comprising a cord having one end connected to the tennis racquet and said cord being fed through at least two or more pulleys;
- and a plurality of mechanisms which are adjustably mounted on a support to control exertion of a towing force on the cord and set the cord free, interactively, during the execution of a stroke, in a sequence corresponding to the following points and phases of a swing:
- a) interactively exerting a towing force from a waiting stance to an end of a back swing and from a lowest point of a loop of the swing to full stretching of the body and hitting arm during serve training;
- and
- b) setting the cord free, at full stretching of the body and hitting arm during serve training.
