Abstract
Abstract This invention relates to a liquid directional flow apparatus which includes mounting means such as an elongate mounting tube having an inner portion attached to an outlet pipe of a swimming pool or other liquid retaining structure and liquid directional flow means associated with the mounting means. Preferably the mounting tube has an outer portion which is enlarged relative to the inner portion and functions as a socket for the liquid directional flow means which is preferably a pivot flow ball member. The arrangement is such that in the case of the apparatus being installed to an outlet pipe of the swimming pool or other liquid retaining structure which is offset to the planar or substantially planar outer face of a wall of the swimming pool or structure that the liquid directional flow means may be adjusted to any desired setting or orientation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
206 words
A liquid directional flow apparatus including: an elongate mounting tube having an inner portion engageable in an outlet pipe of a swimming pool and an outer portion which is enlarged relative to the inner portion and wherein the outer portion has a side wall that curves outwardly and then inwardly relative to the longitudinal axis of the elongate mounting tube; an eyeball shaped nozzle having a channel extending therethrough which is mounted in the outer portion of the mounting tube and wherein the outer surface of the nozzle has a curvature at least substantially complementary to the inner surface of the outer portion whereby said nozzle may be pivoted relative to said mounting tube; and an inner clamping ring having a curved inner surface engageable with a curved outer surface of said outer portion of the mounting tube and pivotable thereto during installation; and locking means engageable with said inner clamping ring to orient the inner clamping ring in a direction substantially parallel to the plane of an outer wall of the swimming pool when the liquid directional flow apparatus is installed in said outlet pipe to enable the eyeball nozzle to be oriented in a direction substantially normal to the plane of said outer wall.
Claim 2
Dependent Claim
206 words
A liquid directional flow apparatus including: an elongate mounting tube having an inner portion engageable in an outlet pipe of a swimming pool and an outer portion which is enlarged relative to the inner portion and wherein the outer portion has a side wall that curves outwardly and then inwardly relative to the longitudinal axis of the elongate mounting tube; an eyeball shaped nozzle having a channel extending therethrough which is mounted in the outer portion of the mounting tube and wherein the outer surface of the nozzle has a curvature at least substantially complementary to the inner surface of the outer portion whereby said nozzle may be pivoted relative to said mounting tube; and an inner clamping ring having a curved inner surface engageable with a curved outer surface of said outer portion of the mounting tube and pivotable thereto during installation; and locking means engageable with said inner clamping ring to orient the inner clamping ring in a direction substantially parallel to the plane of an outer wall of the swimming pool when the liquid directional flow apparatus is installed in said outlet pipe to enable the eyeball nozzle to be oriented in a direction substantially normal to the plane of said outer wall.
Claim 3
Dependent Claim
35 words
Liquid directional flow apparatus as claimed in claim 1 wherein the inner portion of the mounting tube in use is rigidly secured to a fixing tube located in the internal bore of the outlet pipe.
Claim 4
Dependent Claim
50 words
A liquid directional flow apparatus as claimed in claim 1 wherein the locking means includes an outer clamping ring having an inner surface engageable with the curved outer surface of the outer portion of the mounting tube and also being screw threadedly engaged with the inner clamping ring in use.
Claim 5
Dependent Claim
54 words
A liquid directional flow apparatus as claimed in claim 1 wherein the inner clamping ring includes a rear part which extends through an aperture in the outer wall of the swimming pool in use and wherein said inner clamping ring may be retained in position by a washer screw threadedly engaging said rear part.
