20140117112 | Oscillating Shower Head Massager - An oscillating shower massager that provides a rotating or oscillating spray pattern that may be adjusted by the user. The oscillating shower massager has a housing with a forward facing water discharge outlet and a rotating side discharge outlet. A water driven gear system drives the rotating side discharge outlet. A series of stop pins are provided that may be used to adjust the rotation. When the stop pins are retracted, the rotating discharge outlet turns a full 360 degrees, allowing the user to spray all the walls and ceiling of the shower stall to facilitate cleaning. When the stop pins are extended, the rotating side outlet provides an oscillating spray pattern. A heated shaving mirror is incorporated onto the front of the housing. | 05-01-2014 |
20140239093 | BALL SHAPED WATER SPRINKLER SYSTEM - A traveling sprinkler system comprising: a sphere shaped surface; at least one wheel over a circumference of the sphere shaped surface, where the at least one wheel divides the sphere into a first half and a second half; a plurality of holes on both the first half and the second half of the sphere shaped surface; a water hose receptacle, where the water hose receptacle receives a flow of water from a water hose; and wheel gears within the sphere, where the flow of water transfers over the wheel gears to enable the movement of the at least one wheel and the flow of water transfers through the plurality of holes creating a sprinkling action. | 08-28-2014 |
20150034737 | DRIVE MECHANISM FOR A SPRINKLER - A sprinkler includes a hollow shaft to which a positioning part, a gear casing, a pipe are respectively connected to the hollow shaft. The positioning part and the pipe are respectively connected to a first end support and a second end support of a base. The positioning part has multiple grooves defined in a tubular portion thereof. A hollow positioning rod has a ratchet portion which is resiliently formed thereto. The hollow positioning rod is rotatably mounted to the hollow shaft and the ratchet portion is engaged with the grooves of the positioning part. The hollow positioning rod has a toothed portion which is engaged with an output gear of the gear casing. The gear casing is driven by a hydraulic power so as to swing the pipe periodically. The resilient ratchet portion allows the gear casing and the pipe to swing easily, and no metal spring is required. | 02-05-2015 |
20160023222 | OSCILLATING SPRINKLER - The sprinkler has a drive motor with a gear assembly with a drive gear that is engaged with the sun gear of the flow adapter. A motor housing has a gear train chamber for the gear assembly, and a first chamber and a second chamber each providing for a path of flow. A switching mechanism has a valve block for alternatingly blocking and establishing the path of flow through one of the first chamber and the second chamber of the motor housing. A water wheel alternating in rotation between a clockwise direction and a counter clockwise direction based on the path of flow from one of the first chamber and the second chamber of the motor housing and engaging the gear assembly to rotate the gear assembly back and forth around the sun gear of the flow adapter and simultaneously moving the oscillating nozzle. | 01-28-2016 |
