Tennis score keeping device

Abstract

The two part device is received within the recess in a tennis racquet handle. The first part is fixed within the recess and has a surface imprinted with scoring indicia. The second part is rotatably mounted on the first part and has a viewing window. The viewing window is aligned with selected scoring indicia on the first part surface as the second part is rotated. Detents cooperate to insure proper alignment between the window and the indicia. The second part has a raised portion, preferably in the shape of an indicia, to facilitate gripping the exterior surface of the second part.
