Abstract

A sprinkler includes a pop-up deflector plate that is engageable with a brake assembly in an extended position. A brake module is secured to a sprinkler body and includes a rotatable connector coupled with the brake assembly. The pop-up deflector plate is disposed adjacent the nozzle and engages the rotatable connector in the extended position.

First claim

The invention claimed is:

1. A sprinkler comprising:
a sprinkler body;
a brake module secured to the sprinkler body and including a rotatable connector coupled with a brake assembly, the brake module being selectively detachable from and re-attachable to the sprinkler body;
a nozzle module cooperable with the sprinkler body, wherein the nozzle module comprises a nozzle top directly coupled with a nozzle base, the nozzle top including a deflector plate receiving channel therein, and the nozzle base including a nozzle; and
a deflector plate cooperable with the nozzle module and disposed facing the nozzle, the deflector plate being displaceable in the nozzle module between a retracted position and an extended position, the deflector plate including a stream deflector surface and a torque shaft, and the deflector plate being independent of the brake module and being selectively placed within and removable from the nozzle module, wherein the torque shaft is engaged with the rotatable connector in the extended position,
wherein the rotatable connector includes a channel with a cross-sectional shape, wherein the torque shaft is shaped corresponding to the cross-sectional shape to engage the channel and to transfer torque between the deflector plate and the rotatable connector, wherein the cross-sectional shape is square, and wherein the torque shaft is shaped to fit in the square shape.

2. A sprinkler according to claim 1 , wherein the deflector plate includes a shaft section that is sized corresponding to the deflector plate receiving channel in the nozzle top such that the deflector plate is displaced between the retracted position and the extended position in the nozzle top.

3. A sprinkler according to claim 2 , wherein the stream deflector surface is integrated with the shaft section.

4. A sprinkler according to claim 1 , wherein the torque shaft is engaged with the rotatable connector in the retracted position.

5. A sprinkler according to claim 1 , wherein the cross-sectional shape comprises linear ridges, and wherein the torque shaft comprises linear splines that are engageable with the linear ridges.

6. A sprinkler according to claim 1 , wherein the nozzle module is connected to the sprinkler body in a snap fit.

7. A sprinkler according to claim 1 , wherein the rotatable connector is positioned so as to act as a stop limit for the deflector plate in the extended position.

8. A sprinkler according to claim 1 , further comprising a base unit to which the nozzle module is secured, the base unit having connecting structure connectable with a source of water under pressure.

9. A sprinkler according to claim 1 , further comprising a spring acting between the rotatable connector and the deflector plate, the spring biasing the deflector plate toward the retracted position.

10. A sprinkler according to claim 1 , wherein the deflector plate comprises a breakaway diffuser tab.

11. A sprinkler according to claim 1 , wherein the brake module, the nozzle module and the deflector plate are modular components.

12. A sprinkler comprising:
a sprinkler body;
a brake module secured to the sprinkler body and including a rotatable connector coupled with a brake assembly, the brake module being selectively detachable from and re-attachable to the sprinkler body;
a nozzle module cooperable with the sprinkler body, wherein the nozzle module comprises a nozzle top directly coupled with a nozzle base, the nozzle top including a deflector plate receiving channel therein, and the nozzle base including a nozzle; and
a deflector plate cooperable with the nozzle module and disposed facing the nozzle, the deflector plate being displaceable in the nozzle module between a retracted position and an extended position, the deflector plate including a stream deflector surface and a torque shaft, and the deflector plate being independent of the brake module and being selectively placed within and removable from the nozzle module, wherein the torque shaft is engaged with the rotatable connector in the extended position,
wherein the brake module, the nozzle module and the deflector plate are modular components,
the sprinkler comprising a plurality of brake modules with varying braking characteristics, a plurality of nozzle modules with varying flow characteristics, and a plurality of deflector plates with varying stream disbursement characteristics, wherein the pluralities of brake modules, nozzle modules and deflector plates are selectively and independently attachable to the sprinkler body.

13. A sprinkler assembly including a plurality of interchangeable modular components, the sprinkler assembly comprising:
a sprinkler body including compartments for securing the interchangeable modular components;
the plurality of interchangeable modular components comprising:
a plurality of brake modules each securable to the sprinkler body, the plurality of brake modules respectively having varying braking characteristics from no braking to maximum braking, each of the brake modules including a rotatable connector;
a plurality of nozzle modules each securable to the sprinkler body, each of the plurality of nozzle modules including a nozzle having a nozzle size, wherein the respective nozzle sizes of the plurality of nozzle modules reflect varying flow characteristics; and
a plurality of deflector plates each cooperable with the plurality of nozzle modules and disposed adjacent the nozzle, the deflector plates each being displaceable in the respective nozzle module between a retracted position and an extended position, the deflector plates each including a stream deflector surface and a torque shaft, wherein the torque shaft is engaged with the rotatable connector in the extended position.

14. A sprinkler assembly according to claim 13 , wherein at least one of the brake modules comprises a brake assembly to which the rotatable connector is coupled.

15. A sprinkler assembly according to claim 13 , wherein each of the rotatable connectors includes a channel with a cross-sectional shape, and wherein each of the torque shafts is shaped corresponding to the cross-sectional shape to engage the channel and to transfer torque between the deflector plate and the rotatable connector.
