Abstract
Dual control flushing mechanism enables a user to select complete or partial flush of a toilet tank. The complete flush is obtained by lifting a mobile assembly containing a float, while maintaining the float intact. The partial flush is obtained by lifting the mobile assembly and simultaneously opening the float so that it fills with water and thereafter sinks, causing a blocking valve to engage and terminate the flushing process before a full flush has been effected.
Claims21
A dual-control flushing apparatus for selective operation of a complete or partial evacuation of a flushing tank having an evacuation orifice, comprising:
- an axially-displaceable mobile assembly having a blocking valve, means for movably mounting said assembly in said flushing tank whereby said blocking valve blocks and unblocks said evacuation orifice of the flushing tank;
- said assembly further including an overflow tube having an upper portion with an upper orifice and a lower portion with a lower orifice, said lower portion of said overflow tube comprising a float located above said blocking valve, said float being submersible;
- a blocking device positioned partially within said float and axially movable therein and adapted to be pressed against a seat formed by an edge of said lower orifice of said overflow tube into a closed position, so as to stop entry of water into said float, first and second push button control systems, said second push button control system including a thruster rod operatively connected to said blocking device for spacing said blocking device from said seat into an open position by a force exerted by said thruster rod associated with said second push-button control system;
- said first push-button control system comprising a first transmission system for lifting said mobile assembly to unblock said evacuation orifice for a complete evacuation of the flushing tank, and said second push-button control system comprising a second transmission system including said thruster rod for enabling the positioning of said blocking device into said open position so as to enable entry of water into said float, thereby causing said float to fall and interrupt a flushing process for a partial evacuation of the flushing tank, said first push-button control system and said second push-button control system being arranged so that activation of a first push-button of said first push-button control system for a complete evacuation does not result in any action on said second push-button control system, and activation of a second push-button of said second push-button control system for a partial evacuation activates said first push-button control system for lifting said mobile assembly.
