Abstract:
1. A urinal comprising: a urinal having a lower portion, a middle portion and an upper portion, the lower portion including a receptacle with a drain, the middle portion including a backstop and sidewalls for guiding liquid waste to the drain and connecting the lower portion to the upper portion, the upper portion containing a manifold and a flush mechanism; the manifold positioned above the receptacle and comprising a chamber having a floor that includes a plurality of holes positioned adjacent the backstop, allowing fluid in the manifold to flow from the manifold down the backstop into the receptacle; the flush mechanism being disposed above the manifold and including a flush reservoir pivotable about a pivot axis within a flush reservoir frame, the flush mechanism being in communication with a water inlet and a flush actuator; the flush reservoir including a housing having an opening, the housing being nonsymmetrical about the pivot axis, the pivot axis being substantially parallel with the backstop, and having a fill position and a flush position, the flush reservoir configured to remain in the fill position when empty and movable to the flush position when a threshold volume of water is in the reservoir, the flush reservoir opening being in fluid communication with the water inlet when in the fill position and the flush reservoir opening being in fluid communication with the manifold when in the flush position; the flush actuator for controlling the position of the flush reservoir, the flush actuator releasably retaining the flush reservoir in the fill position when the threshold volume of water is present in the flush reservoir; and the flush reservoir having a flow edge along the housing, the flow edge adjacent the opening and parallel with the pivot axis.
