Tilting-bowl toilets
First Claim
1. 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, whereinsaid 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, andafter 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.

Abstract
Tilting Bowl Toilet comprises a frame, a toilet basin, and a tilting bowl. The tilting bowl is supported below the toilet basin to receive and hold water/waste delivered from the toilet basin. The tilting bowl tilts to discharge its content to drainage. The tilting bowl at standby is sustained to stay in a horizontal position by forces applied to the tilting bowl creating a resultant sustaining turning moment about its support axis. When the turning moment produced by the tilting bowl with its content becomes larger than the sustaining turning moment, the tilting bowl moves to a tilted position to discharge its content. The effective support axis shifts with respect to the tilting bowl as guided by a motion guide.
