Abstract
A buoy for supplementing the buoyancy of a swimmer's legs comprising, a unitary foam member (11) having a flexible generally water impervious skin (41) adapted for engagement with and selective retention by the legs of a swimmer, the foam member having spaced cylindrical elements (12,13), being of generally prolate circular cross section (14,15), the circular cross section (15) of one of the cylindrical elements being substantially smaller than the circular cross section (14) of the other of the cylindrical elements and a shank (25) spacing and joining the cylindrical elements and being substantially narrower than the circular cross section of either of said cylindrical elements (12,13).
Claims10
A buoy for supplementing the buoyancy of a swimmer's legs comprising, a unitary foam member adapted for engagement with and selective retention by the legs of a swimmer, said member having spaced cylindrical elements, said cylindrical elements being of generally prolate circular cross section, the circular cross section of one of said cylindrical elements being substantially smaller than the circular cross section of the other of said cylindrical elements in that engaging the buoy with the cylindrical element of smaller cross-section submerged provides lesser buoyant effect than with the other cylindrical element submerged, shank means spacing and joining said cylindrical elements, said shank means being substantially narrower than the circular cross section of either of said cylindrical elements, and a flexible generally water impervious skin encompassing the entirety of said unitary member.
