Description




BACKGROUND OF THE INVENTION




(1) Field of the Invention




The present invention relates to a portable and foldable chamber excretion pot, and more particularly, a chamber excretion pot having a seat folding mechanism, which can be developed for use and foldable after being finished using it, especially suitable for carrying in a car.




(2) Description of the Prior Art




The most embarrassing matter for people who are driving his/her car along a rural road or on a freeway where no establishment of washrooms for public use can be found when he/she suddenly feels like unbearably excretory. Although a conventional excretion bag may be used to release the embarrassment, such a bag has no supporting means so that the user is forced to crouch over it for a long time, and in the worst case, polluting the surroundings with excretion.




There is a portable chamber excretion pot utilizing an upper half structure of a conventional closes tool. However, it is not foldable and it is bulky as well. As a result, it is impossible to put aside under the car seat. Besides, the user has to put up with the danger of beating his/her head against the car roof when crouching over the chamber pot in a limited height of the car.




SUMMARY OF THE INVENTION




The present invention has been made in order to eliminate the inconvenience inherent to the conventional techniques as mentioned above. Accordingly, it is an object of the present invention to provide a portable and foldable chamber excretion pot whose volume can be decreased when folded to save occupied spacing for the convenience of putting aside under a car seat.




It is another object of the present invention to provide a portable and foldable chamber excretion pot whose folder mechanism can be settled horizontally for the user to stably and comfortably sit thereon.




It is still another object of the present invention to provide a portable and foldable chamber excretion pot whose lid stands behind his/her hip so as to prevent the excrement from spattering here and there in the car.




To achieve these and other objects, the portable and foldable chamber excretion pot comprises an developable/foldable pot assembly with an excretion inlet thereon, a seat folder mechanism able to make a plurality of sustainers stand up or lie down on the pot assembly, a sloped surface is formed when the sustainers are standing up so as to settle the pot horizontally on the car seat thereby enabling the user to comfortable and stably sit thereon, and an excretion bag is disposed in the pot assembly under the seat pad for accepting the excrement. After excretion is finished, the bag is taken out together with its contents by hermetically sealing the bag opening. By folding the seat folder mechanism, the volume of the pot assembly is minimized and can be put away under the car seat.
