  • Patent number: 5823899
    Abstract: A games racket frame comprising a head portion defining a string bed of main strings and cross strings, a shaft portion and a handle portion wherein at the crown of the head portion a cross-section through the head portion perpendicular to the string bed reduces in width towards the string bed, and the main strings wrap around the head instead of passing through drilled string holes. The invention has the potential advantages of improving breakage resistance properties and allowing a player to play close to the wall shots.
