Inventor: REINHARDT J DR MED
IPC: A63B49/03
Filed: 1990-06-12
Abstract: A racket (10) which is suitable, above all, as a tennis or squash racket has a handle (6) and a frame (7) formed from two parallel hollow profiles, the two hollow profiles being held together by a connecting web in such a way that a groove-type depression (13) is formed on the outside of the frame (7).
