Tennis racket
First Claim
1. Tennis racket with a handle upon which a grip covering is applied, comprising a sensor incorporated into the handle and forming a means for measuring a gripping force with which the handle is grasped by hand of a tennis player wielding the tennis racket, said sensor being electronically connected to an acoustic signal emitter in the handle in a manner forming a means for emitting an acoustic indicator signal when at least one determined preadjustable limiting value of the gripping force is reached;
- wherein the handle is made up of two half shells between which at least one spring element is placed as a means for applying a force in a direction acting to press the half shells apart.

Abstract
A tennis racket with a handle (4), preferably wrapped with a grip strip (3), which improves training of gripping techniques through the use of a sensor (6) that is incorporated into the handle (4), by which it is possible to measure the gripping force with which the hand of a tennis player wielding the tennis racket grips handle (4). Sensor (6) is connected to an electronic evaluation circuit (7) which is integrated into the handle, so that an indicator signal, especially an acoustic indicator signal, is caused to be emitted by the evaluation circuit (7) when a determined preadjustable limiting value or different limiting values of the gripping force is reached.
