Abstract: A toilet includes a bowl and a vertically-elongated jet hole disposed within a portion of the bowl, near a top of the bowl between a rear of the bowl and a side of the bowl. The vertically-elongated jet hole is configured to direct flush water around an inner surface of the bowl to wash the inner surface of the bowl. The bowl does not include a rim that overhangs any portion of the bowl above the vertically-elongated jet hole.

Abstract: A urinal is disclosed as having a spreader assembly. The spreader assembly includes a spreader body that may be mounted to the urinal, and a spreader mat. The spreader mat includes a series of spray holes. The spreader body is connected to a water supply, and a perimeter of the spreader mat is sealed to the spreader body. Each spray hole of the spreader mat is oriented to direct water onto a particular area of the urinal, when water is supplied to flush the urinal.

Abstract: A toilet includes a bowl having a vertically-elongated jet orifice near a top of the bowl that is designed to introduce flush water into the bowl from an interior water channel through a surface of an inner wall of the bowl, such that the flush water is directed around the inner wall of the bowl to wash the inner wall. The toilet also includes a shelf for directing the flush water. The toilet is a gravity-fed toilet that does not include an overhanging rim.

Abstract: An actuation mechanism for a dual flush toilet that includes a rotatable pivot pin including a body and an extension extending outwardly from the body; a first lever configured to contact the extension after a predetermined rotation of the first lever, such that continued rotation of the first lever rotates the pivot pin a first rotation to actuate the first flush mode; and a second lever configured to contact the extension after a predetermined rotation of the second lever, such that continued rotation of the second lever rotates the pivot pin a second rotation to actuate the second flush mode; wherein the first rotation is different than the second rotation.

Abstract: An actuation mechanism comprising a first handle, a second handle, a housing, a link arm member provided within the housing and pivotally coupled to the handles, and a moveable stop member provided within the housing. The first handle may be mounted to a first side of a toilet tank, and the second handle may be mounted coaxially relative to the first handle on the first side. The housing may be mounted to a second side of the tank. A rotation of one of the first and second handles results in rotation of the link arm member being limited by the moveable stop member such that the link arm member is permitted to rotate a first amount. Rotation of both the first and second handles results in movement of the moveable stop member such that the link arm member is permitted to rotate a second amount greater than the first amount.

Abstract: A flush valve for a toilet has a valve body with a flow passage that narrows non-linearly down from the valve seat. The flow passage is formed by a surface that follows a polynomial expression so as to define a computationally derived flow profile that more closely follows the narrowing exhibited by falling water as it accelerates under gravity. The non-linear flow profile of the valve reduces the presence of air in the valve after a flush cycle is initiated so that greater flush efficiency can be achieved. The flush valve can also have a wide mouth overflow that narrows to improve flow in an overflow situation.
