Abstract: A swimming lane wave suppressor, for use in suppressing waves and for use in the demarcation of swimming pool lanes, comprised of two cylindrical cores having a plurality of fins radially extending from their outer surface, the inner surface of the first core having a larger diameter than the inner surface of the second core. The fins are positioned substantially coextensively in a lane of each core. At least one spacer is circumferentially positioned between and connected to the core members and fins. A flotation assembly is axially positioned within the first core member having the larger inside diameter and compression fit against the inner surface thereof. The flotation assembly includes a hollow, water tight cylindrical body having a central axial opening for receiving a cable or like device for stringing a plurality of wave suppressors together to form a lane demarcation.

Abstract: The invention is directed to a lockable support float, preferably blow molded, for use in swimming pools and the like. It comprises at least first and second expanded members having mateable ends which are adapted to slide over and lock onto a rope. Each member includes an opening that is eccentrically positioned therethrough and alignable with each other for sliding engagement with a rope. Each member includes either a female or a male locking member comprising concentrically positioned annular groove and annular extension, respectively. The annular groove includes at least two projections which extend over a portion of the groove, and the annular extension includes a flange around the perimeter thereof for locking engagement with said projections. By rotation of the locked members the respective openings therethrough become offset with respect to each other and any rope positioned therethrough is securely locked in the openings of the float.
