## Abstract

A portable half bathroom is disclosed. The portable half bathroom may be in a compact condition or in an expanded condition. In the compact condition, the portable half bathroom looks like a regular cabinet. Collapsed and folded panels are attached to the cabinet. All side and back walls are racked on their relative sides of the cabinet when the portable half bathroom is not in use. In the expanded condition, the panels are unfolded and expanded to form an enclosure.

## Background
BACKGROUND OF THE INVENTION
This invention relates to restrooms or bathroom in general, and mobile or portable half bathroom in particular. Some outdoor activities and most unavoidable natural and manmade disasters increase the chance of defecation and urination in uncontrolled areas such as backyards, forests, water sources, (rivers, lakes, and the like) in a non hygienic manner; therefore enhances the risk of transmission of diseases such as cholera. The availability of portable bathrooms minimizes these risks.
Because they lack privacy, comfort, means of hygiene and convenience, prior arts in this field of invention have failed to provide the complete prevention to the health and environmental issues in relation to defecation and urination.
The portable half bath room of this invention looks a conventional cabinet on four wheels with breaks when not in use. Said portable half bathroom consists of a toilet that is deployable and retractable, foldable and stretchable covering means or walls for all sides, doors, flooring, roofing, wall mirror, sink, and faucet and water tank, that are deployable from the top surface of said cabinet.
The portable half bathroom of this invention can be one solution to the world's sanitation problems. It promotes the prevention of the spread of diseases such as cholera in disaster situations and evacuations such as during a major earthquake. In general, the portable half bathroom of this invention is used in places and occasions where and when conventional bathrooms are hard to reach for different reasons. It can be used for large or extended family houses or apartments that have shortage of bathrooms, in trailers and trailer parks, for RVs, on parking places, for construction sites, on barbecue areas, for camping, for road works, in medical facilities and the like.
Portability of a bathroom becomes important when space and mobility is considered. The current invention provides both mobility and resolves the issue of shortage in space through its portability.

DESCRIPTION OF PREFERRED EMBODIMENTS
The portable half bathroom of this invention is represented by the number 20. The portable half bathroom 20 looks like and is used as a conventional cabinet 10, until the need for half bathroom surfaces. FIG. 1 shows the portable half bathroom in a compact condition. FIG. 1 to FIG. 4 illustrate the cabinet 10 having a top surface 32, wall panels 2, doors 3, ceiling panels 5, release buttons 6 and 6′, a four-leg toilet 7 having legs 18, a sink 9 having an opening 33, a faucet 11, containers 12, a tank 15, electrical plugs 16, wheels with brakes 23, a toilet paper holder 27, a back panel 30, handles 35, lighting systems 24 and 24′, and everything that make the portable half bathroom 20 tact in place. Until it is needed to be used as a bathroom, the cabinet 10 is used as a regular cabinet and furniture of a house.
When the need to use the portable half bathroom 20 surfaces, all the wall panels 2, and the doors 3, get pulled out via pulling-handles 25 or by pressing the release button 6, and unfold from the sides of the cabinet 10 to form a desired size room. The toilet 7, the tank 15, and the faucet 11, deploy for use then after. The toilet 7 comes out manually or automatically when cabinet doors 21 are opened. A collapsible venting system (In examples of the present disclosure, the venting system was known to a person of ordinary skill in the art on or before the filing date of the present application.) extends from the bottom of the toilet out up through the back wall of the portable half bathroom. The water tank 15 will be unfolded from a hinge 19 to a sitting position. The faucet 11 and the sink 9 will then be accessible for use. FIG. 2 shows that the wall panels 2 each have a first ply and a second ply. The second plies are pulled up along the vertical direction. In examples of the present disclosure, second plies are thinner than the first plies. The top ends of the second plies are higher than the top surface 32 of the cabinet 10 after the second plies are pulled up.
The disposable biodegradable waste container 12, which will be called bio-d-cont for short from here on, is hooked under a toilet seat 13 and the bottom of the sink 9. Bio-d-cont 12 is water resistant.
As shown on FIG. 3, for outdoor use, the ceiling panels 5 will be deployed from the back of the cabinet 10 and unfold to cover. Also for outdoor use, a securing device (In examples of the present disclosure, the securing device was known to a person of ordinary skill in the art on or before the filing date of the present application.) secures the portable half bathroom 20 to the ground to prevent it from movement caused by wind, flood, and the like. FIG. 4 shows the portable half bathroom in an expanded condition. The wall panels 2 and ceiling panels 5 are unfolded and expanded.
