Abstract

A sprinkler apparatus comprises a sprinkler motor configured to rotate an output gear and a sprinkler tube configured to move in a repeating pattern in response to rotation of the output gear. The sprinkler apparatus further comprises a tube adapter interposed between the output gear and the sprinkler tube. The tube adapter is fixed in relation to the sprinkler tube. The tube adapter includes a first set of teeth and the output gear has a plurality of extending flexible fingers defining a second set of teeth which engage the first set of teeth. The output gear and the tube adaptor include water passages through which water advances from the sprinkler motor to the sprinkler tube. The flexible fingers on the output gear allow the second set of teeth to slide over the first set of teeth and provide a torque limiting relationship between the output gear and the tube adaptor.

Claims

1. A sprinkler apparatus comprising:

a sprinkler motor configured to rotate an output gear;

a sprinkler tube configured to move in a repeating pattern in response to rotation of the output gear;

a tube adapter interposed between the output gear and the sprinkler tube,

wherein the tube adapter is fixed in relation to the sprinkler tube, wherein the tube adapter includes a first set of teeth, wherein the output gear has a plurality of extending flexible fingers defining a second set of teeth which engage the first set of teeth, and further wherein each of the output gear and the tube adaptor include water passages through which water advances from the sprinkler motor to the sprinkler tube, and

wherein the flexible fingers on the output gear are configured to allow the second set of teeth to slide over the first set of teeth and provide a torque limiting relationship between the output gear and the tube adapter.

2. The sprinkler apparatus of claim 1 wherein the output gear and the tube adaptor are substantially cylindrical in shape and are coaxial with a portion of the tube adaptor positioned within the flexible fingers of the output gear.

3. The sprinkler apparatus of claim 2 wherein the tube adaptor includes a circumferential groove that engages a circumferential rib on the output gear.

4. The sprinkler apparatus of claim 1 further comprising at least one spray adjustment member positioned on the tube adaptor, wherein movement of the at least one spray adjustment member changes the repeating pattern of the sprinkler tube.

5. A sprinkler comprising:

a water motor comprising a rotatable output gear defining an axis of rotation;

a spray member configured to receive water passing through the output gear;

an adapter member positioned between the output gear and the spray member, wherein the adapter member engages the output gear such that the adapter member is releasably secured to the output gear in a circumferential direction and is releasably secured to the output gear in an axial direction; and

wherein the output gear comprises a first plurality of clutch teeth and the adapter member comprises a second plurality of clutch teeth that engage the first plurality of clutch teeth;

wherein the first plurality of clutch teeth is provided on fingers extending in an axial direction from the output gear; and

wherein the fingers are flexible in order to allow the first plurality of clutch teeth to slide over the second plurality of clutch teeth when a torque on the first plurality of clutch teeth exceeds a threshold torque.

6. The sprinkler of claim 5 wherein the adapter member snaps into the output gear in order to secure the adapter member to the output gear.

7. The sprinkler of claim 6 wherein the output member includes a circumferential rib that fits into a circumferential groove on the output gear when the adapter member snaps into the output gear.

8. The sprinkler of claim 5 wherein the output shaft and the adapter member are substantially cylindrical in shape and coaxial.

9. The sprinkler of claim 5 further comprising an O-ring seal positioned between the output gear and the adapter member.
