Abstract: A toilet is disclosed, having a bowl (400) for receiving human waste and a wiper (402). The bowl (400) is moveable between a waste receiving position and a waste emptied position. This movement is provided based on a waste emptying actuation by a user of the toilet. The wiper (402) is movable to remove residual waste from an inside surface of the bowl (400) by wiping the inside surface of the bowl (400). The movement of the wiper (402) is coupled to the movement of the bowl (400), the wiper (402) being configured to move during the movement of the bowl (400), for at least a part of the movement of the bowl (400) between the waste receiving position and the waste emptied position.

Abstract: A portable restroom is provided. The portable restroom offers features providing users with temporary toilet functions in a physically and emotionally secure environment while offering the owner/operator a cost-effective means of providing service. The portable restroom accomplishing the foregoing objectives includes the features of: improved ventilation; devices for no-touch sanitary safety practice; devices which facilitate personal carry in objects; combination “hover” handle and no touch door latch; a toilet seat with improved durability; improved door hinge installation and performance; improved base fastener retention; an improved base; and high-lift bearing surface and relief.
Abstract: An automatic closure assembly for use with an outhouse or pit commode is disclosed which includes a frame having open upper and lower ends attached to the underside of a bench so as to frame an opening therein over which a toilet seat is hingably mounted atop the bench. The assembly also includes a pair of wedge shaped cradle members which are pivotally attached to front and rear surfaces of the frame which tilt in opposite directions from one another so as to open and close a lower end of the frame. The geometry of the cradle members is such that their centers of gravity are substantially spaced apart from their pivot points so as to provide a gravitational bias of each cradle member tending to urge it at all times toward its closed position against the other cradle member so as to seal the bottom end of the frame to inhibit odors from circulating in or about the outhouse when the assembly is not in use.
Abstract: A toilet seat for composting toilets, which toilet seat comprises a seat ring, a bowl space, a bottom hole of the bowl space, and a separator of liquids such as washing water and urine. The toilet seat is implemented by adapting the inside surface of the front part of the bowl space to be at its upper part essentially vertical, at its middle part almost horizontal, and at its lower part convexly curved so that the center part of the curved area is closer to the rear part of the bowl space than the start and end points of the convexly shaped lower part, whereby liquids entering the front part of the bowl space in the toilet seat are conducted along the inside surface of the front part into a separate liquids collection container, or alternatively, to a treatment process, and that the liquids separator is formed by a shutter adapted to the lower part of the bowl space or below it.
Abstract: A lavatory has a lavatory bowl having an upper side on which a seat edge is provided and a lower side on which a base connection is provided, a dispenser for excrement bags that can be removed individually from the dispenser and secured to the seat edge with the aid of a vacuum, and a vacuum line that enters the lavatory bowl and a suction line. The dispenser has a receptacle for a stack of excrement bags that lie flat one on top of the other. The seat edge is provided with suction holes that can be connected to the suction line. The seat edge and the dispenser are moveable relative to each other and can be brought into a relative position in which the seat edge and the flat-lying excrement bags are parallel to one another, whereby the foremost of the excrement bags can be sucked out of the dispenser by negative pressure in the suction line.
