DESCRIPTION:
BRIEF SUMMARY
Particularly in case of field toilets there in an increasing need for use of toilet systems of separation-type, i.e. having separate feces and urine reception means located beneath a seat opening. In such separation-type of toilets a urine receptacle debouches in the front part of the seat opening whereas a feces receptacle debouches into the rear part of the seat opening as seen in the direction of the person assuming a sitting position above the seat opening.
In the case of toilets of this kind it is very important that the person using the toilet assumes such a sitting position that the urine is received in the receptacle intended therefor and the feces are received in a separate container intended therefor. Should the user instead assume a standing position in front of the seat opening and urinate into the latter, urine will spill into the feces receptacle. This will very negatively influence the function of the toilet system, since the presence of liquid in the feces container considerably inpedes the handling of the filled container while at the same time it increases the leakage risks. The feces receptacle encloses, or more often is formed by, a plastic bag intended to be closed and carried away from the toilet whereas urine could be collected in a separate liquid container or be evacuated straight into the ground.
The main purpose of the invention is to suggest a device wherein the above outlined drawbacks are eliminated.
This purpose is achieved in accordance with the invention in that the toilet seat is located inside a toilet space having sufficient headroom above and in front of said seat in order to allow the user to assume a comfortable sitting position above said opening, but at the same time having insufficient headroom for the purpose of preventing or making considerably difficult urination by said user in a standing position from in front of the seat opening.
Owing to this arrangement the user is forced to make use of the toilet while in a sitting position and the risks for incorrect usage of the toilet thus are efficiently eliminated.
Preferably, the ceiling height increases continuously from the area above the toilet seat to the area in front of said seat. The result is that the roof may be given a very simple configuration well fitting the normally forwardly-inclined sitting posture of persons using the toilet. Owing to this arrangement the headroom may be kept very low, with the result that the intended effect of the toilet in this respect is applicable also in case of comparatively short individuals.
Preferably, the toilet space is formed by a mobile container having a roof portion which is movable between a raised position of use in which the above ceiling height or headroom space conditions exist, and a lowered position of transport in which the height of the container is reduced. This toilet design makes the toilet very suitable for field usages since the toilet, when not in use, may be collapsed to a very low height, i.e. a height not greatly exceeding the height of the toilet seat itself. Thus, the toilet could be easily handled by the persons carrying the toilet without the risk of the latter tipping over.
Furthermore, also transport by means of vehicles could be carried out without any tipping-over risks. In addition, it may be transported in vehicles with low headroom space, for instance in trucks of pick-up type having canvas type of covers or low height stationary superstructures.
Preferably, the container is formed by an upwardly open lower section including a bottom and side walls, one of said side walls having a preferably closeable entrance opening, and by a top section including side walls projecting downwards from the roof portion and bridging the vertical space between the lower section side walls and the roof in said raised position. This design provides a toilet space that is well enclosed and shut off from view from outside while at the same time it is easily accessible for use.
In addition, the roof portion preferably is pivotable about a hinge positioned above t
