ABSTRACT:
A swimming pool pop-up fitting having a pop-up head responsive to the intermittent application of water under pressure to reciprocate between retracted and projected positions for directing a jet of water over the adjacent inner surface of a swimming pool from a nozzle in the head.
The pop-up fitting includes a fixed retainer having cams that are engageable by camming pins carried by the nozzle head to incrementally rotate the head during its movement between retracted and projected positions. The pins can be removed and the head constrained against rotation to convert the head from a rotary head to a pop-up head which is rotationally stationary or fixed.
The pop-up head includes a stem which mounts the nozzle. The nozzle has diametrically opposed nozzle openings which are selectively alignable with an opening in the stem. Location of an insert in one of the nozzle openings reduces its diameter so that selective positioning of the nozzle insert adjacent the stem opening converts the fitting from a high water flow rate to a lower water flow rate.
The nozzle is retractable into a relatively large diameter nozzle recess located above a smaller stem recess which receives the stem. The wall defining the nozzle recess is provided with camming surfaces or cams which, because of the ample space available, are made relatively large and consequently more durable and more sensitive to the camming action of the nozzle pins. Also, location of the cams in the large nozzle recess presents a minimum obstruction to water flow and promotes higher water flow rates through the fitting.
