Abstract
Abstract The pool cleaning pole assembly includes an elongated cleaning pole having an improved adapter releasably connected to the bottom cleaning end thereof, and a cleaning accessory releasably connected to the adapter. The adapter includes (a) a first member having an upper hollow tubular portion releasably connected in the pole lower end by spring biased pins and bearing a base below the pole, and (b) a second member rotatably secured to the underside of the base for limited rotation. The second member has a bracket to which a pool cleaning accessory such as a brush, vacuum head, etc., is releasably connected. The adapter also includes a pin or the like inserted in aligned openings in the base and second member and connected to a Bowden wire or push rod passing up through the hollow tubular member and pole to the pole's upper end where it can be easily moved up and down by the operator to lock the second member against rotation or free it to rotate. Alternatively, the locking device may be clamp operated by the wire or rod. The adapter and assembly are efficient, inexpensive and durable.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
194 words
An improved adapter for a pool cleaning pole, said adapter comprising, in combination: (a) a first member comprising 1. a generally vertically extending cylindrical hollow tubular portion, said hollow tubular portion bearing first releasable connection means for releasable connection thereof to the inside of a pool cleaning pole, and 2. a substantially flat base portion lying in a substantially horizontal plane; (b) a second member having 1. a flat portion lying generally in a plane substantially parallel to the plane of said base portion, and 2. a second releasable connection means for releasable connection of pool cleaning accessories to said second member; (c) pivot means rotatably interconnecting said base portion and said flat portion, and (d) locking means for releasably securing said flat portion and said base portion together to prevent relative rotation thereof, (e) wherein said limit means comprises one of a pin releasably disposed in alignable openings in said base portion and said flat portion and a clamp fixed to said base portion and releasably clampable to said flat portion and remote actuating means connected to said pin or clamp for releasably remotely withdrawing said pin or clamp from said flat portion.
