Abstract:
1. A power conduit for supplying energy to a pool cleaner body to cause said body to travel through a water pool along a substantially random travel path and to capture debris as it moves along said path, while avoiding the formation of persistent coils or knots in the conduit, said conduit comprising: first and second axially stiff elongate members each having first and second ends spaced by greater than one foot, each of said stiff elongate members configured to transfer energy therealong from its said first to its said second end; an axially flexible elongate member having first and second ends and configured to transfer energy therealong from its said first to its said second end; said first and second axially stiff members being respectively connected to said first and second ends of said axially flexible member to form a continuous energy transfer path for transferring energy from said first axially stiff member first end to said second axially stiff member second end; a proximal coupler for coupling said first axially stiff member first end to a stationary fitting; a distal coupler for coupling said second axially stiff member second end to said cleaner body; a swivel coupling in said conduit for enabling at least one of said axially stiff members to swivel axially relative to said fitting and said cleaner body; and an axially flexible coupling in said conduit for enabling at least one of said axially stiff members to variably angulate relative to said fitting and said cleaner body.
