  • Patent number: 7201677
    Abstract: A tennis net winder for positioning within a tennis net support post, the tennis net winder comprising a frame having a face plate, having a plurality of apertures for securing the tennis net winder to the support post, the face plate having rearwardly extending support walls secured by a rear wall, the rear wall and face plate having aligned apertures for support of a worm gear member, the extending support walls having aligned apertures for support of a beveled gear and take up drum assembly, the face plate having a generally longitudinal rectangular opening aperture having a guide roller slidably mounted on a cross bar, the tennis net cable passing under the guide roller and through the take up drum, the take up drum being formed with a helical groove such that operation of the worm gear by a crank handle takes up or releases cable on the take up drum, the take up assembly, the winder assembly and frame being coated with a weather impervious coating, such as gold plating.

  • Patent number: 6945578
    Abstract: The ball retrieval and storage device includes a container having a hollow interior for storing a substantial number of tennis balls. At least a portion of the container bottom is formed by one or more movable rod members which are movable to allow the balls to enter through the bottom of the container. A user can retrieve a ball lying on the ground by forcing the bottom of the container down over the top of the ball. The ball engages the movable rod member and moves it slightly upwardly which allows the ball to enter the container as the container is progressively forced down over the top of the ball compressing the ball. The movable rod members are formed of a material having an elastic memory such that for use over time, the movable rod members will not permanently deform so as to decrease the efficacy of the ball retrieval and storage device.

    Abstract: The ball retrieval and storage device includes a container having a hollow interior for storing a substantial number of tennis balls. At least a portion of the container bottom is formed by one or more movable rod members which are movable to allow the balls to enter through the bottom of the container. A user can retrieve a ball lying on the ground by forcing the bottom of the container down over the top of the ball. The ball engages the movable rod member and moves it slightly upwardly which allows the ball to enter the container as the container is progressively forced down over the top of the ball compressing the ball. The movable rod member ultimately passes the equator of the ball and a stop means mounted on the container limits the upward movement of the movable rod member. The raised movable rod member thus is held momentarily in a fixed position by a stop means to allow a major portion of the ball to pass through the opening in the container bottom.
