Patent ID: 8065756

Claim:
A toilet comprising: a frame defining a chamber, a toilet basin associated with said frame to define said chamber into an upper chamber region and a lower chamber region, said toilet basin defining at least one basin discharge opening in communication between said upper chamber region and said lower chamber region, a tilting bowl disposed generally in said lower chamber region, said tilting bowl defining a fluid-receiving volume, said tilting bowl mounted for pivoting movement relative to said toilet basin between a substantially horizontal first position to receive and hold fluid communicated through said at least one basin discharge opening, and a second position permitting flow of fluid from said toilet basin, through said at least one basin discharge opening, and from said fluid-receiving volume into said lower chamber region, wherein said tilting bowl is sustained to remain in said first position by forces applied to said tilting bowl producing a sustaining turning moment about an effective support axis at least sufficient to counterbalance the turning moment produced by said tilting bowl with its content, said tilting bowl moves from said first position toward said second position when said sustaining turning moment is smaller than said turning moment produced by said tilting bowl with its content, and after said tilting bowl starts moving, said support axis shifts along a relative motion guide to decrease said sustaining turning moment to accelerate said tilting bowl movement to effectively discharge its content to said lower chamber region.
