Cam operated swimming pool cleaning nozzle
View Patent ↗A swimming pool cleaning head. Implementations may include a cleaning head assembly having a housing having a cam assembly with an upper section, a lower section, and a rotatable section disposed between the upper section and the lower section. A stem having an outlet configured to eject a stream of water under water therethrough under water pressure force may also be included, the stem extending through the cam assembly. The stem may also include at least one pin slidably engaged within the cam assembly.
1. A swimming pool cleaning head assembly comprising:
a cam housing;
a cam assembly removably coupled to the cam housing, the cam assembly comprising an upper section, a lower section and a rotatable section slidably disposed between the upper section and the lower section and rotatable between a first extent and a second extent, the cam assembly comprising a plurality of saw tooth members;
a locking ring removably coupled to the cam housing over the cam assembly, the locking ring comprising a plurality of lugs configured to engage with the cam housing and substantially prevent rotational movement of the upper section and lower section of the cam assembly;
a stem extending through the cam assembly, the stem comprising a pin slidably engaged with the plurality of saw tooth members, the pin configured to incrementally rotate the stem clockwise through the saw tooth members during vertical translation of the stem through water pressure force and slidably rotate the rotatable section of the cam assembly from its first extent to its second extent; and
wherein the cam assembly is configured to automatically reverse the incremental rotation of the stem to counterclockwise.
2. The swimming pool cleaning head assembly of claim 1 , wherein the locking ring further comprises an annular surface comprising at least one angled projection extending toward a cap ring rotationally coupled to the cam housing, the cap ring comprising raised projections on an annular surface extending toward the locking ring, wherein rotation of the cap ring in relation to the locking ring causes the raised projections on the cap ring to engage the angled projections on the locking ring to resist rotational movement of the cap ring in one direction.
3. The swimming pool cleaning head assembly of claim 1 , further comprising a cap ring removably coupled to the cam housing over the locking ring, the cam housing further comprising a locking arm extending from a side of the cam housing, flexibly engaging the cap ring and resisting rotational movement of the cap ring in one direction.
4. The swimming pool cleaning head assembly of claim 1 , further comprising a plurality of ridges on an annular surface of the cam housing, the lower section of the cam assembly comprising a plurality of mating grooves on an annular surface of the lower section of the cam assembly, wherein coupling the plurality of ridges of the cam housing with the plurality of grooves of the cam assembly resists rotational movement of the cam assembly within the cam housing.
5. A swimming pool cleaning head assembly comprising:
a cam housing comprising a cam assembly removably coupled to the cam housing through a locking ring, and a stem extending through the cam assembly, the stem comprising at least one pin slidably engaged with the cam assembly;
a plurality of ridges on an annular surface of the cam housing and a plurality of grooves on an annular surface of the cam assembly that mate with the plurality of ridges on the cam housing when removably coupled thereto and resist rotational movement of the cam assembly within the cam housing; wherein the cam assembly is configured to both incrementally rotate the stem clockwise through the pin as the stem extends from the housing under water pressure force and to automatically reverse the incremental rotation of the stem counterclockwise.
6. The swimming pool cleaning head of claim 5 , wherein the cam assembly comprises an upper section, a lower section, and a slidable section, wherein the slidable section is rotationally slidable with respect to the lower section and the upper section.
7. The swimming pool cleaning head assembly of claim 5 , further comprising a cap ring removably coupled to the cam housing over the locking ring, the cam housing further comprising a locking arm extending from a side of the cam housing, flexibly engaging the cap ring and preventing rotational movement of the cap ring in one direction.
8. The swimming pool cleaning head assembly of claim 5 , wherein the locking ring further comprises an annular surface comprising at least one angled projection extending toward a cap ring rotationally coupled to the cam housing, the cap ring comprising raised projections on an annular surface extending toward the locking ring, wherein rotation of the cap ring in relation to the locking ring causes the raised projections on the cap ring to engage the angled projections on the locking ring to resist rotational movement of the cap ring in one direction.
9. A swimming pool cleaning head comprising:
a cleaning head assembly having a housing comprising a cam assembly having an upper section, a lower section, and a slidable section rotatably disposed between the upper section and the lower section, and a stem comprising an outlet configured to eject an intermittent stream of water under water therethrough under water pressure force, the stem extending through the cam assembly, the stem comprising at least one pin slidably engaged within the cam assembly, the stem comprising a locking ring comprising a plurality of lugs configured to engage with the housing and also configured to substantially prevent rotational movement of the upper section and the lower section of the cam assembly.
10. The swimming pool cleaning head of claim 9 , wherein the pin is configured to intermittently engage with a saw tooth member comprised within the upper section and slidable section and to slidably rotate the slidable section while the stem is under water pressure force.
11. The swimming pool cleaning head of claim 9 , wherein the slidable section comprises a channel in communication with an angled channel comprised in the upper section, and the slidable section is configured to accommodate through slidable rotation, the pin, as it enters the channel.
12. The swimming pool cleaning head assembly of claim 9 , wherein the locking ring further comprises an annular surface comprising at least one angled projection extending toward a cap ring rotationally coupled to the cam housing, the cap ring comprising raised projections on an annular surface extending toward the locking ring, wherein rotation of the cap ring in relation to the locking ring causes the raised projections on the cap ring to engage the angled projections on the locking ring to resist rotational movement of the cap ring in one direction.
13. The swimming pool cleaning head assembly of claim 6 , wherein the slidable section comprises a plurality of saw tooth members.
14. The swimming pool cleaning head assembly of claim 9 , wherein the slidable section comprises a plurality of saw tooth members.
