First Claim
Patent Images
1. A flush mechanism for attachment to a urinal, comprising:
- a housing With an external surface which provides water inlet means and water outlet means for, respectively, receiving water from a water supply and for delivering water to the urinal during a flush;
a depressible push-button disposed on the external surface of the housing, the push-button and the housing together forming a substantially sealed and continuous external surface around the flush mechanism;
flush means responsive to the depression of the push button to release a predetermined amount of flush water to the urinal, the flush means comprising a switch responsive to depression of the push button, a battery, a battery-powered solenoid responsive to activation of the switch, an electronic module in the form of a printed circuit which transmits a signal from the switch to the solenoid, and a valve associated with the solenoid which, in response to a signal from the printed circuit, opens for a predetermined time to allow water to pass through the flush mechanism from the inlet means providing said predetermined amount of water to the urinal.

Abstract
A flush mechanism is provided for a urinal, wherein the working components are provided within a two-part, sealed housing. A button is provided on the cap portion of the housing to flush the urinal. Depression of the flush button signals a battery-powered solenoid to open for a preset amount of time, allowing water into the mechanism from a supply line. The flow of water in each flush is further regulated by an adjustable flow-control valve. All working components can be accessed for replacement or maintenance with only a minimum of disassembly of the flush mechanism.

9. In combination with a urinal, a flush mechanism provided in a user-accessible position above the urinal to provide flushing water to the urinal, the flush mechanism comprising:
-
a housing with an external surface which provides water inlet means for receiving water from a water inlet pipe associated with the urinal and water outlet means for delivering water to an outlet pipe which supplies water to the urinal during a flush; a depressible push-button disposed on the external surface of the housing, the push-button and the housing together forming a substantially sealed, and continuous external surface; flush means responsive to depression of the push button to release a predetermined amount of flush water to the urinal, the flush means comprising a switch responsive to depression of the push button, a battery, a battery powered solenoid responsive to activation of the switch, a printed circuit which transmits a signal from the switch to the solenoid, and a valve associated with the solenoid which, in response to a signal from the printed circuit, opens for a predetermined time to allow water to pass through the flush mechanism from the inlet means, and an adjustable flow control valve which delivers water to the outlet means, providing said predetermined amount of water to the urinal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
