  • Patent number: 5253874
    Abstract: A racquet intended to be used to propel and catch a VELCRO-covered ball for recreational sports. The racquet includes a rim surrounding a convex plate, the outer surface of the plate being a catching surface covered with a pad of adhesive filament material (VELCRO). A latex membrane is stretched across the rim over the inner concave surface of the plate to define a hollow drum chamber into which the latex membrane may flex when a ball is struck. The membrane acts as a resilient striking surface, and vibrates over the drum chamber to produce a loud sound wave when the ball is struck.
