Abstract
A rigid mount orbitor sprinkler assembly incorporates a deflector plate configuration that is configured for both spinning/rotating motion as well as orbital or wobbling motion around the center of a spool assembly. The sprinkler includes a spider ingress opening cooperable with a spider barrier that in combination permit inevitable spider ingress while preventing spider access or contact with certain moving parts of the sprinkler.
Claims20
A sprinkler comprising:
- a sprinkler body;
- a nozzle associated with one end of the sprinkler body;
- a cap secured to or integral with an opposite end of the sprinkler body, the cap including a central opening and at least one spider ingress opening positioned radially outward of the central opening;
- a deflector plate assembly supported by the cap and including a deflector plate at an upstream end facing the nozzle, a spool assembly supported in the central opening of the cap, and a counterbalance weight at a downstream end, wherein the deflector plate assembly is pitched at an angle relative to the sprinkler body;
- and
- a spider barrier disposed in engagement with the cap and defining an enclosure over the at least one spider ingress opening.

A sprinkler comprising:
- a sprinkler body having a longitudinal axis;
- a cap secured to or integral with the sprinkler body and including a central opening and at least one spider ingress opening positioned radially outward of the central opening;
- a nozzle;
- and
- a deflector plate assembly including a deflector plate at one end disposed facing the nozzle, a counterbalance weight disposed at an opposite end, and a spool assembly positioned in the central opening and disposed between the deflector plate and the counterbalance weight;
- and
- a spider barrier disposed in engagement with the cap and defining an enclosure over the at least one spider ingress opening,
- wherein the deflector plate assembly is rotatable about a rotation axis, and wherein the deflector plate assembly is supported in the sprinkler body such that the rotation axis is pitched relative to the longitudinal axis and such that the deflector plate assembly is configured to wobble about the longitudinal axis.
