  • Patent number: 7363672
    Abstract: An automatic pool cleaner accessory is provided comprising a tubular assembly (6) for connection to, or for inclusion in, a pool cleaner suction hose (4). The tubular assembly includes first and second tubular members (8, 9) generally coaxial with each other and freely relatively rotatable about a common axis in an inoperative condition of the accessory. Means (16) are provided for inhibiting relative rotation of the members in the operative condition with suction applied to the interior thereof. The accessory is preferably used in combination with a connector tube (7) for installation in a suction hose assembly, the connector tube comprising a central portion (21) of substantially rigid tube having at one end a first terminal portion (22) with its axis extending at an incline to that of the straight central portion, and at the other end a second terminal portion (23) having its axis likewise extending at an incline to the axis of the straight central portion.

  • Publication number: 20040046384
    Abstract: A connector tube (7) is provided for installation in a suction hose of an automatic pool cleaning assembly, the connector tube comprising a central portion (21) of substantially rigid tube having at one end a first terminal portion (22) with its axis extending at an incline to that of the straight central portion, and at the other end a second terminal portion (23) having its axis likewise extending at an incline to the axis of the straight central portion. In end view taken along the axis of the central portion, the axis of the first terminal portion diverges from the axis of the second terminal portion to provide asymmetric connector tube.
