  • Patent number: 10676904
    Abstract: The present disclosure describes toilet flappers having an adjustable length cord. For example, the present disclosure describes a toilet flapper having a body and two arms. The body has a top surface and a bottom surface. On the top surface, there is a raised portion housing a cord, a locking mechanism, and a spring. In order to install the toilet flapper, a user can grab a hook attached to the end of the cord and pull enough of the cord out of the raised portion so that the user can attach the hook to, for example, a flush lever. Afterwards, the user can press down on the raised portion in order to activate the locking mechanism and prevent any more of the cord from being pulled back into the raised portion by the spring.

    Abstract: A dual flush-volume outflow valve assembly for a toilet tank is provided. The outflow valve assembly comprises a base having an opening configured to pass water out of the toilet tank, a lower outflow tube section extending upwardly from the base, and an upper outflow tube section adjustably coupled to and extending upwardly from the lower outflow tube section. The lower outflow tube has a hollow interior and includes a high-volume flush valve positioned to pass a first, larger volume of water from the toilet tank to the toilet bowl when opened. The upper outflow tube section has a hollow interior and includes a low-volume flush valve positioned to pass a second, smaller volume of water from the toilet tank to the toilet bowl when opened. In some embodiments, the hollow interiors of the upper outflow tube section and the lower outflow tube section are positioned over and in line with the opening.

  • Patent number: 6332229
    Abstract: A gravity drop-toilet uses main water via electronically programmed valves to rinse separate areas of a bowl (71) in sequence via appropriately located and pointing jet orifices (136, 138,140) with about 70% less water than siphon toilets. Electronically timed valve (180) hydraulically causes a pair of bellows (110) to compress and expand and thereby reversibly pivot a mechanical linkage to retain waste in the bowl and drop waste via a vertical waste passageway into a sewer pipe (30). The linkage comprises a transfer arm (118) that pivots a rotating arm of a cup (128) and flap actuating arm (104) to pivot a springy plate (78) upward against a dimple (80) formed on under the side of the flap (30) which thereby aligns itself against the bottom edge (74) of the bowl (71). A urine version of this mechanism uses apertures (174, 175) that they enclose combine to center defecating sitters over a cylinder outlet (48) of the bowl.

  • Patent number: 6282731
    Abstract: A multiple variable flush storage tank toilet has been developed as preferred state-of-the-art to improve the means of reducing the amount of water used in a water flush type toilet. The improved mechanism within the toilet storage tank relies on a partitioned smaller and larger compartmented space in accordance with that state-of-the-art. The variable means of flushing to obtain a multiplicity of smaller water flushes plus a larger water flush has been obtained by use of “V”-indented polygons. The mechanism for flushing is operated by using a conventional exterior tank handle and is adaptable for a variety of polygons. All functions of the mechanism are simplified beyond that of the current conventional toilet. The variety o flushings are duplicated as use of the toilet is continued.

  • Patent number: 6178567
    Abstract: The flush system for a toilet provides a discharge pipe upstanding within a flush tank of the toilet. The pipe has a bottom with a bottom opening through which water from the flush tank travels to the toilet bowl of the toilet. The bottom is connected to the first inlet controlled by a first valve and a second inlet controlled by a second valve. The first inlet is at a higher elevation than the second inlet with respect to the bottom opening. The flush system further comprises actuating handle for selectively moving the first and second members in a first mode or a second mode such that in the first mode, only the second inlet is opened and in the second position the first and second inlets are opened.

  • Patent number: 6173456
    Abstract: A double-cistern water conservation sanitary water tank comprises two tanks: an external oval tank (9) for evacuating solid waste and an internal round tank (8) for flushing liquid waste mounted within and at a level above a bottom wall of the external oval tank (9), and two actuating handle for operating the tanks. The external oval tank (9) includes a water entrance valve (3) and an elbow-shaped water outlet (4) having one end connected to a first outlet valve (11) inside the external oval tank (9). The internal round tank (8) includes a water entrance valve (1) and a vertical water outlet (2) having one end connected a second outlet valve (10), an intermediate portion connected to the second end of the elbow-shaped water outlet (4), and the other end forming a common drain (7).

  • Patent number: 6041452
    Abstract: A toilet water tank is provided with a water discharging seat which is in turn provided in the top thereof with an upright tube, a high water discharging port and a low water discharging port. The high and the low water discharging ports are movably covered with a cover respectively. The cover is fastened with the upright tube which is provided with a guide wheel member. A flush handle is located outside the toilet water tank such that the flush handle is connected with a control rod extending to the water discharging seat for locating two chains between the two covers and the control rods. The chains are located by the clamps such that the chains can be installed or replaced with ease and speed.

  • Patent number: 5887292
    Abstract: A flush control system, for releasing different amounts of water from the holding tank of a toilet into a discharge pipe, includes an auxiliary tank mounted in the toilet holding tank. The auxiliary tank has a volume which is less than the volume of the holding tank, and has one end wall assembly with a flapper valve communicating with the interior of the auxiliary tank and another flapper valve in a different wall communicating with the interior wall of the holding tank. A chamber is formed between the two walls in which the flapper valves are located. The bottom of this chamber has an opening which is placed over the discharge pipe opening in the bottom of the holding tank. A balancing aperture is formed through one of the other walls of the holding tank to permit water flow to take place between the auxiliary tank and the holding tank.

  • Patent number: 5881399
    Abstract: A dual flush mechanism equipped with a two independent flush valves which are each separately controlled by a separate spring loaded button. The flush valves are at different heights in the toilet tank such that actuation of the upper flush valve, by pressing a first button on top of the tank, will produce a short flush, while pressing of the second button will actuate the lower flush valve to produce a long flush. Pivot rods are pivotably supported on a common axis below the first and second buttons. The upper end of each pivot rod is coupled through a spring to its respective push button on top of the tank. The opposite ends of the pivot rods are coupled respectively through a chain to the upper and lower flush valves. Pressing the first button exerts a downward force through the spring on the first pivot rod to raise the opposite end thereof which in turn raises the upper flush valve. Pushing the second button actuates the second pivot rod in the same manner to raise the lower flush valve.
