Abstract: An individual tension meter (1) for measuring tension in a racquet string (9), includes a graspable body (10) and a stress member (2) for stressing the string (9) that are movable relative to each other by pivoting, elastically deformable return elements (3) configured to urge the graspable body (10) and the stress member (2) relative to each other back into a neutral angular position, measurement elements for measuring a magnitude representative of the relative pivoting between the graspable body (10) and the stress member (2), and computation elements for computing the tension of the string as a function of the measured magnitude. The graspable body (10) and the stress member (2) have a first possibility of pivoting relative to each other in a first direction and a second possibility of pivoting relative to each other in a second direction opposite from the first direction.

Abstract: A handle-expander element (1) for the handle (2) of a sports racket, in particular a tennis racket is made up of an elongate body (10) presenting an “inside” face for applying along the handle of the racket and an “outside” face for holding by the player, each of the inside and outside faces of the elongate body (10) being made up of a plurality of longitudinal facets. The handle-expander element includes at least one tongue (113, 115) extending an end facet (13, 15) that extends transversely to the axis of the end facet. A set of handle-expander elements, a handle-expander, and a method of modifying the diameter size of the corresponding handle are also described.
