Pop-up head for water jet-pool cleaning system

Claim 1

A system for cleaning the inner surfaces of a swimming pool, said pool having a pool water filter, means for withdrawing water containing suspended deleterious matter from said pool and conducting said water to said filter and means for returning said suspended deleterious matter is separated from said water, and said filtered water from said filter to said pool, said system comprising a plurality of rotating water jet delivery assemblies located at spaced points upon the inner surface of said swimming pool, each said assembly comprising: a. a generally cylindrical housing havinG a threaded inner end adapted to be connected to inlet plumbing conduits communicating between said housing and said filter and having an outer open end mounted substantially flush with said inner surface; b. a rotary jet delivery head adapted to constantly rotate 360* having primary cleaning water jet apertures therein to project pressurized streams of jet cleaning water in directions tangential to the axis of rotation thereof and in adjacent parallel and scrubbing relation to the inner surface of said pool and having means defining secondary water jet apertures disposed to project water jet streams in a rotary direction at an acute angle to the rotating axis of said rotary jet delivery head and also at an acute angle to the adjacent surfaces of the pool to maintain said deleterious matter scrubbed from said inner surface of said pool by said primary water jets in suspension in said pool water for removal by said filter; and c. a shaft rotatably mounted within said generally cylindrical housing at its lower end and affixed to said rotary jet delivery head at its upper end, said shaft holding said rotary jet delivery head in operative position with respect to said cylindrical housing and being rotatably journaled within said housing such that water supplied to the inner end of said housing forces said water jet delivery head to a position spaced from the outer end of said housing and said pool inner surface.

Claim 2

A system for cleaning the inner surfaces of a swimming pool, said pool having a pool water filter, means for withdrawing water containing suspended deleterious matter from said pool and conducting said water to said filter and means for returning said suspended deleterious matter is separated from said water, and said filtered water from said filter to said pool, said system comprising a plurality of rotating water jet delivery assemblies located at spaced points upon the inner surface of said swimming pool, each said assembly comprising: a. a generally cylindrical housing havinG a threaded inner end adapted to be connected to inlet plumbing conduits communicating between said housing and said filter and having an outer open end mounted substantially flush with said inner surface; b. a rotary jet delivery head adapted to constantly rotate 360* having primary cleaning water jet apertures therein to project pressurized streams of jet cleaning water in directions tangential to the axis of rotation thereof and in adjacent parallel and scrubbing relation to the inner surface of said pool and having means defining secondary water jet apertures disposed to project water jet streams in a rotary direction at an acute angle to the rotating axis of said rotary jet delivery head and also at an acute angle to the adjacent surfaces of the pool to maintain said deleterious matter scrubbed from said inner surface of said pool by said primary water jets in suspension in said pool water for removal by said filter; and c. a shaft rotatably mounted within said generally cylindrical housing at its lower end and affixed to said rotary jet delivery head at its upper end, said shaft holding said rotary jet delivery head in operative position with respect to said cylindrical housing and being rotatably journaled within said housing such that water supplied to the inner end of said housing forces said water jet delivery head to a position spaced from the outer end of said housing and said pool inner surface.
