  • Patent number: 5873758
    Abstract: A water ski handle 10 is provided which exhibits a high level of rigidity and strength such that the water ski handle 10 does not deform significantly even when experiencing high loads during use. The water ski handle 10 includes a rigid frame 20 of generally triangular construction. The frame 20 includes an apex bend 22 to which a ski rope R is attached and a left bend 24 and right bend 26. A base section 30 extends between the left bend 24 and right bend 26 and provides a region for grasping by a hand H of a skier. A left section 34 and right section 37 extend rigidly forward from the base section 30 at opposite ends thereof to the apex bend 22. The frame 20 is constructed with a low density polymeric foam core 60 with longitudinal fibers 70 surrounding the foam core 60 and helical fibers 80 and perpendicular fibers 86 surrounding the longitudinal fibers 70 with all of the fibers 70, 80, 86 embedded within an epoxy resin matrix 90.
