ABSTRACT:
Improved tennis racket including a head, a handle, and a two hand hollow elongated grip member. The head is strung with elastic strings installed within a selected range of tension to provide a selected coefficient of restitution. The handle has a flexure section of selected length and of selected stiffness extending from the head to the grip member. Recovery characteristics and stiffness are selected to provide a desired coefficient of restitution and playability for a designated style of racket. The grip member has an inner end, an outer end, and a first longitudinal opening extending from the outer end and terminating at a selected distance to receive a portion of the handle. A second larger opening extends inwardly from the outer end and adjoins the first recess to define an annular cavity around a portion of the flexure section and an outer periphery of selected length along the grip member.
