The piston/seal includes a sealing material located on a top surface thereof. This sealing material can be a thermoplastic elastomeric coating material. | 02-06-2014 |
20140090158 | Toilet Flush Valve Assemblies - Flush valve assemblies are described herein which include a valve body; a flush valve cover detachably connected to a flush line; a pivot mechanism capable of opening and closing the flush valve cover upon actuation; wherein the flush line is connected at a first end to a flush actuating device and at a second end to the flush valve cover, the line being capable of raising and lowering the cover upon actuation; and a float situated above the cover and connected to the flush line at a point between the first and the second ends of the flush line or by a separate float line connected to the cover. The float is sufficiently buoyant and capable of resisting the force of flowing water and keeping the flush valve cover open to allow flush water to pass through the valve body before closing the cover when the valve body is installed on a toilet. | 04-03-2014 |
20140259342 | Click Fit Toilet Flush Handle Lever Assembly - A toilet lever assembly, including: (a) a sleeve dimensioned to pass through a toilet tank wall; (b) a rotatable post extending through the sleeve; (c) a toilet flush handle mounted to the end of the rotatable post that is positioned outside of the toilet tank; (d) a nut received onto the end of the sleeve that is positioned outside of the toilet tank; and (e) a lever housing mounted to the end of the post that is positioned inside of the toilet tank, the lever housing comprising: (i) an actuator for moving a toilet lever to cause a flush when the post is rotated, and (ii) a biasing mechanism for rotating the post back to a neutral position. | 09-18-2014 |
20140259343 | Dual Mode Flush Actuator - A flush actuator for engaging a flush valve. The flush actuator provides a mechanism assembly for automatically flushing the flush valve. A sensor provides a presence detection to trigger the automatic flushing. A reduced flush or standard flush cycle may be initiated. | 09-18-2014 |
20140283291 | Voice Command Flush Module - The invention is a self-contained module placed within residential toilet tanks to allow the toilet to be flushed using voiced word command. The existing toilets flush handle remains installed and operable. The device operates the toilet flush valve by lifting the toilets existing flush bar. The device provides a low cost means of converting the majority of existing toilets to operate in a voice/word/phrase activated no-touch flush mode. The device is powered by four (4) AA batteries which will last 2-3 years in residential use. | 09-25-2014 |
20140298578 | TOILET TANK LEVER - A toilet tank lever, which is consisted of a first lever body, a second lever body and a fastening element, wherein a handle is connected to one end of the first lever body and a first meshing part is set on its another end, a screw hole is set on the first meshing part, a second meshing part is set on one end of the second lever body, a through hole is set on the second meshing part, the second meshing part correspondingly meshes with the first meshing part, the screw hole is correspondingly communicated with the through hole for the fastening element passing through to fasten on; a pair of wings set on the head of the fastening element are provided for the user to rotate the fastening element by fingers, to thereby adjust the operating position of the lever. | 10-09-2014 |
20150376884 | DUAL FLUSH HANDLE CONTROL - Disclosed are various embodiments for a dual flush handle system. A first handle lever is configured to rotate in a direction by a first predetermined angle of rotation to initiate a first flush of a toilet. A second handle lever is configured to rotate in the direction about a second predetermined angle of rotation to initiate a second flush of a toilet. | 12-31-2015 |

A shaft extends through the locking member and a flush handle is connected to the first end of the shaft. The second end of the shaft protrudes from the locking member and is connected to a positioning member which is connected with a link. The second end of the shaft has two plates with a slot formed therebetween. The locking member has a groove which is located in the recess of the positioning member and a pin extends through the positioning member and is engaged with the groove of the locking member to connect positioning member to the locking member. The shaft is removed from the positioning member by squeezing the two plates of the shaft. | 12-29-2016 |
004250000 | Seat operated | 1 |
20100325785 | AUTOMATICALLY FLUSHING TOILET - An automatically flushing toilet in which an extension arm is attached to a horizontal bar to which the toilet seat is attached. When the toilet seat is raised, one end of the extension arm moves downward, causing a rod on the end of the inner tube of a telescoping member located primarily inside the tank compartment of the toilet to move so that it is positioned atop a pivoting member located inside a cut-out on the same end of the extension arm. When the toilet seat is then closed, the one end of the extension arm moves upward, pushing the pivoting member against the rod and causing the rod to force the inner tube of the telescoping member upward. The inner tube is pivotally connected to a trip lever, which causes the toilet to flush. | 12-30-2010 |
