Abstract
A device for measuring stiffness of the string bed of a racket, includes a main body adapted to sit on the string bed; a force measuring device mounted to the main body; a biasing arrangement connected to the force measuring device and adapted to be connected to the string bed for deflecting the string bed in relation to the force measuring device, and causing the force measuring device to output a signal corresponding to the deflection of the string bed; a stop connected to the main body in a manner such that the stop is not acted upon by the deflection of the string bed when deflected by the biasing arrangement and which limits the string bed to a predetermined amount of deflection by the biasing arrangement; a switch to provide an output when the string bed is deflected to at least a predetermined position; a display for displaying the stiffness of the string bed in accordance with the signal output from the force measuring device in response to a change in the output from the switch as the string bed moves from the deflected position to an undeflected position; and a positioning device to repeatably position the string bed stiffness measuring device on the string bed.
