Carrying handle provided, designed as a portable container made of plastic, the upper part serving as a fresh water container with a funnel-like collecting basin with a central opening to the lower part, a pressure flushing device built into the fresh water container in the form of a water pump _T - ~ a is equipped with hinged glasses and a hinged lid, the lower part of which serves as a faeces and waste water container has a central receiving opening on its upper surface, which is coincident with the outlet opening of the collecting basin and can be closed by a slide.

The known water flush toilets of this type are commonly releasable on the floor of the vehicle in question mounted so that its two parts are dismantled and taken away for fresh water or for emptying are kca ^ en, but a special one for use require a fixed installation space on the floor of the vehicle. Since now vehicles of the type under consideration here are common If you only have very little space available, the most rational use of which is required, such a space appears Arrangement not very advantageous.

The innovation is based on the idea of using a space that is as space-saving as possible for the purpose of efficient use of space Arrangement to be provided. Based on this, the task of the innovation is to create an arrangement in which the toilet does not take up permanent floor space.

This object is achieved according to the invention in that the two for the purpose of installation in Sahrank furniture with lower

Height-trained parts of the toilet ready-to-use one above the other at a horizontal, in a suitable manner Height attached axis pivotable cabinet flap are detachably mounted that a pressure flushing device Water pump and three automatically acting one-way valves with elastically loaded valve bodies are provided, namely a suction-side inlet valve and a pressure-side outlet valve for the water pump, as well as an air inlet valve for the water tank, and that the upper part with hinged glasses and possibly a hinged lid is provided, which are both articulated on a common pivot axis so that they can be pivoted under frictional load, that they are not pivoted under their own weight. Through the A combination of these measures is a space-saving installation of the water flush toilet on a cabinet flap, for example on a flap of a washbasin made possible in such a way that it can be folded up when not in use and is therefore invisible and only needs to be unfolded for use. The innovation not only saves space causes, but also eliminates the need for a special by a wall or a curtain to provide space to be locked.

The assembly on the cabinet flap is expediently carried out by means of one on the one hand on this, on the other hand on the Upper part of the toilet attacking snap fastener. These. Training in assembly gives the opportunity to the parts of the toilet can be removed from their assembly by means of a simple handle, for example the water tank to fill with fresh water, or to empty the faeces or waste water container.

According to a further feature of the innovation, the tension lock is designed as a removable special part, by means of a substantially rectangular guide piece used for fastening in a longitudinal section rectangular indentation in the wall of the upper part is slidably and removably mounted. This training of the surge lock enables not only its replacement if necessary, but also a change the tension within certain limits by moving the guide piece in the indentation.

The over-tensioning fastener is expediently composed of a sheet metal flap which is hinged to the guide piece via a link is and the closure end is deformed to two adjacent hook-shaped channels, one of which one arranged on the lower part reinforcing rib, the other one a steel bracket attached to the cabinet flap reaches under.

In terms of the general requirement to achieve the lowest possible overall height, is close to another feature the innovation provided that the water pump is designed as an elastic bellows made of plastic. Already through relatively slight compression of the bellows is a considerable reduction in volume and thus a corresponding water displacement achieved for the purpose of rinsing. The valves assigned to the water pump and likewise the air inlet valve for the water tank are expediently designed as metal-free cone-cone valves conical closing body made of elastic rubber by means of a valve opening which engages at its pointed end penetrating rubber strand with its other end in the axis of movement of the closing body on one part

formed so that the pump volume is reduced by pressing by hand, whereby a corresponding amount of the The water contained therein is pressed out and causes the rinsing process. Expands when the pump body is released this under the effect of its own elasticity - possibly also under tension of a built-in "return" spring and sucks in fresh water from the container. To ensure this function, the pump is also on the suction side an inlet valve, provided on the pressure side with an outlet valve; the water tank of the upper part 1 also has an inlet valve for admitting air as water is withdrawn.

The lower part 2 is connected to the upper part 1 via an intermediate piece 3, the construction of which will be explained below connected in a liquid-tight manner. In addition to the one attached to a side wall by means of a screw cap 20 and a seal 20a closable emptying nozzle 20b and a »also attached to a side wall - in the drawing not visible - handle in the ceiling 21 a central
