CROSS REFERENCE TO RELATED APPLICATIONS

The present application is a continuation-in-part of, and entitled to the earlier filing date and priority of, co-pending U.S. patent application Ser. No. 11/351,615 which is assigned to the same assignee as the current application entitled “BEACH JON,” which was filed on Feb. 11, 2006, the disclosure of which is incorporated by reference.

FIELD OF INVENTION

This invention relates to portable toilet facilities, and more specifically, to portable toilet facilities that are manipulable by an individual user such that the facilities may be erected and broken down by the individual user.

BACKGROUND

It is a natural human condition to expel waste, or, in colloquial terms, “use the restroom.” It is also usual human condition to travel from one's home, and, by extension, away from convenient restroom facilities. For instance, when one visits a campground, park, or beach, there may not be readily-accessible restroom facilities on such a site. When one finds space to set up his or her chair or towel at a crowded beach, that space may be a significant distance from the nearest restroom facility such that a walk thereto is tiring and otherwise inconvenient. Also, when one ventures into the wilderness or a national park, for example, while fishing a river or an oceanfront, there will often be no restroom facilities provided other than at the park entrance or ranger station. The fisherman will inevitably face the difficult decision of leaving the fishing spot and returning to the distant facilities to relieve himself or of polluting the environment by going to the bathroom in the wilderness area.

Therefore, having a proximate restroom facility is a desirable condition for campers, park visitors, outdoorsmen, and beachgoers. Certain attempts in the prior art have been made to address this need.

U.S. Pat. No. 7,200,878 to Payne discloses a collapsible portable toilet with a chair frame including a built-in foldable seat with a hole, a disposable absorbent fragrant flexible refuse bag extending through the hole in the seat and draped around the seat, the refuse bag attached to an underside of the seat, a roof support frame and a bag removably attached to a top of the roof with curtain material draped around the roof for privacy. The chair frame contemplated by the '878 presents a risk that the toilet apparatus might collapse during use, which could result in undesirable unsanitary conditions for the user.

U.S. Pat. No. 7,185,375 to Movsas discloses a collapsible portable toilet apparatus with a privacy screen. The '375 patent contemplates a folding chair with a platform and an opening therein containing a removable receptacle. Telescoping poles attached to the back of the chair and a collapsible planar frame attached to the top of the poles provide support for a foldable canopy and privacy screen. The folding chair in the '375 patent requires an additional step in setting up and collapsing the portable toilet device.

U.S. Pat. No. 7,103,926 to Rasberry shows a portable latrine with an annular seat with an opening formed therein and a lip formed with a perimeter of the opening that extends downwardly and orthogonally from a seat top surface. A biodegradable sack has an elastic open top end for fitting beneath the seat opening.

U.S. Pat. No. 7,020,909 to Ciotic discloses a portable self-contained vented commode with a frame, a pivoting toilet seat, and an aligned removable collection container capable of being dumped post receipt of human waste, which container is disposed beneath the toilet seat. A flexible hose with a DC powered fan thereon is attached to the frame for collection of vapors from the container and the disposal thereof, by creating a positive pressure to expel the vapors to a distant location relative to the frame, through a vent. The '909 patent presents an undesirable level of complexity in incorporating the use of electric or battery power.

U.S. Pat. No. 6,694,538 to Jones shows a portable toilet enclosure assembly with a base assembly including a support base, wheels upon which the support base is mounted; a height adjustable pole assembly being mounted upon the support base; and a curtain rod and curtain support assembly attached thereto. Notably, the '538 patent is not self-contained, rather, it attaches to and encloses an existing toilet.

Accordingly, there remains a need for an easily portable toilet capable of being erected and disassembled with relative ease, providing a space where a user may relieve him or herself in comfort and privacy, while at the same time avoiding the complexities of configuration, manufacturing and assembly to provide an easy-to-use and inexpensive device.
