  • Patent number: 4917533
    Abstract: An improved method and apparatus are provided for resurfacing recreational (e.g., tennis) courts and other surfaces. The apparatus includes self-contained drive means including drive wheels mounted on an elongated frame structure, and additionally supported for rolling movement on a plurality of casters. The apparatus is provided with flexible blade and brush elements for spreading and smoothing court resurfacing material uniformly across the surface. In a forward resurfacing direction, flexible squeegee-type blades, with or without associated brushes, engage the resurfacing material ahead of the device, while flexible brush elements engage the resurfacing material behind the device to erase tracks caused by the drive wheels and casters, and to effect final smoothing and texturing of the resurfacing material. The drive wheels may be moved into and out of ground engaging contact, and a steering device provides for lifting one or the other of the drive wheels out of ground engaging contact.

  • Patent number: 4789265
    Abstract: Method and apparatus are provided for resurfacing one or more adjacent tennis court surfaces. An elongated, box-like frame structure, supported for rolling movement on a plurality of casters, is provided with flexible blade and brush elements for engaging, spreading, and smoothing court resurfacing material at a predetermined thickness as the structure traverses the court surface. In accordance with method aspects of the invention, the device is movable in one direction to resurface an entire tennis court, and after lateral movement to an adjacent second court area, reversible to move in the opposite direction to resurface an entire second court surface. For a given resurfacing direction, the flexible blade elements engage the resurfacing material ahead of the device while the flexible brush elements engage the resurfacing material behind the device to effect final smoothing.
