Abstract

A sprinkler assembly including a fluid deflecting structure including a plurality of spaced apart tines defining a plurality of slots. The tines include a first pair of symmetric tines and a second pair of symmetric tines disposed orthogonally to the first pair of symmetric tines. The tines includes outer edges of varying configuration to define tine and slot geometries and patterns.

First claim

What is claimed is:

1. A sprinkler comprising:
a frame having a body having an inlet, an outlet and an internal passageway extending between the inlet and the outlet to define a longitudinal sprinkler axis, the frame including two frame arms extending distally from the body about the outlet to define a plane bisecting the body such that the arms are equidistantly disposed about the plane; and
a planar fluid deflecting structure supported by the frame arms, the fluid deflecting structure having a center aligned along the longitudinal sprinkler axis, a first peripheral edge defining a first diameter of the deflecting structure about the center, and a second peripheral edge defining a second diameter of the deflecting structure about the center, the second diameter being greater than the first diameter, the deflecting structure having a plurality of tines including:
a first symmetrical tine defining a first axis of symmetry disposed in the plane;
a second symmetrical tine defining a second axis of symmetry disposed orthogonally with respect to the first axis of symmetry, each of the first and second symmetrical tines includes a first portion having a constant width in a first direction normal to the axis of symmetry of the tine and the longitudinal sprinkler axis and a second portion having a variable width in a second direction normal to the axis of symmetry of the tine and the longitudinal sprinkler axis such that the second portion broadens in the direction from the center to one of the first and second peripheral edges, the second portion of each of the first and second symmetrical tines includes an outer edge having a first segment defining a first configuration with respect to the first and second axes of symmetry and a second segment defining a second configuration with respect to the first and second axes of symmetry that is different than the first configuration; and
an asymmetric slot radially disposed between the first and second symmetrical tines, the asymmetric slot includes an open end, a closed end defining a radially innermost portion of the slot, and a pair of spaced apart sidewalls extending from the closed end to the open end, each sidewall includes a first segment defining a first angle with respect to the first and second axes of symmetry and at least a second segment defining a second angle different than the first angle with respect to the first and second axes of symmetry such that the asymmetric slot broadens in a direction from the closed end to the open end.

2. The sprinkler of claim 1 , wherein in the outer edge of the second portion of the first symmetric tine, the first segment defines a first radius of curvature and the second segment defines a second radius of curvature so as to define an inflection point therebetween; wherein in the outer edge of the second portion of the second symmetric tine, the first segment defines a first included angle with respect to the second axis of symmetry and the second segment defines a second included angle with respect to the second axis of symmetry that is different than the first angle.

3. A sprinkler comprising:
a frame having a body having an inlet, an outlet and an internal passageway extending between the inlet and the outlet to define a longitudinal sprinkler axis, the frame including two frame arms extending distally from the body about the outlet to define a plane bisecting the body such that the arms are equidistantly disposed about the plane; and
a planar fluid deflecting structure supported by the frame arms, the fluid deflecting structure having a center aligned along the longitudinal sprinkler axis and a peripheral edge about the center, the peripheral edge including a first peripheral edge and a second peripheral edge, the deflecting structure having a plurality of tines including:
a first symmetrical tine defining a first axis of symmetry disposed in the plane;
a second symmetrical tine defining a second axis of symmetry disposed orthogonally with respect to the first axis of symmetry, each of the first and second symmetrical tines includes a first portion having a constant width in a first direction normal to the axis of symmetry of the tine and the longitudinal sprinkler axis and a second portion having a variable width in a second direction normal to the axis of symmetry of the tine and the longitudinal sprinkler axis such that the second portion broadens in the direction from the center to one of the first and second peripheral edges, the second portion of each of the first and second symmetrical tines includes an outer edge having a first segment defining a first configuration with respect to the first and second axes of symmetry and a second segment defining a second configuration with respect to the first and second axes of symmetry that is different than the first configuration; and
an asymmetric slot radially disposed between the first and second symmetrical tines, the asymmetric slot includes an open end, a closed end defining a radially innermost portion of the slot, and a pair of spaced apart sidewalls extending from the closed end to the open end, each sidewall includes a first segment defining a first angle with respect to the first and second axes of symmetry and at least a second segment defining a second angle different than the first angle with respect to the first and second axes of symmetry such that the asymmetric slot broadens in a direction from the closed end to the open end.

4. The sprinkler of claim 3 , wherein in the first configuration, the outer edge of the second portion of the first symmetric tine defines a first radius of curvature; and wherein in the second configuration, the outer edge of the second portion of the first symmetric tine defines a second radius of curvature so as to define an inflection point therebetween.

5. The sprinkler of claim 3 , wherein in the first configuration, the outer edge of the second portion of the second symmetric tine has a first segment defining a first included angle with respect to the second axis of symmetry and wherein in the second configuration, the outer edge of the second portion of the second symmetric tine has a second segment defining a second included angle with respect to the second axis of symmetry that is different than the first angle.

6. A sprinkler comprising:
a frame having a body having an inlet, an outlet and an internal passageway extending between the inlet and the outlet to define a longitudinal sprinkler axis, the frame including two frame arms extending distally about the outlet to define a plane bisecting the body with the longitudinal axis disposed in the plane; and
a planar fluid deflecting structure supported by the frame arms, the fluid deflecting structure having a center aligned along the longitudinal sprinkler axis and a peripheral edge including a first peripheral edge defining a first diameter of the deflecting structure about the center and a second peripheral edge defining a second diameter of the deflecting structure about the center, the second diameter being greater than the first diameter, the deflecting structure including a plurality of tines including
a first pair of symmetrical tines defining a first axis of symmetry disposed in the plane;
a second pair of symmetrical tines defining a second axis of symmetry disposed orthogonally with respect to the first axis of symmetry, each of the first and second pairs of symmetrical tines includes a first portion having a constant width in a first direction normal to the axis of symmetry of the tine and the longitudinal sprinkler axis and a second portion having a variable width in a second direction normal to the axis of symmetry of the tine and the longitudinal sprinkler axis such that the second portion broadens in the direction from the center to one of the first and seco
