Abstract

Abstract A chemical toilet cabana comprising a plurality of initially identical shell sections, each having a dome-like roof, side walls terminating in a bell-like enlarged lower end and a base flange extending outwardly from the enlarged lower end of the side wall. The base flange is removed from a first shell section to form a cabana top. The dome-like roof is removed from a second shell section to form a cabana base and both the dome-like roof and the base flange are removed from other shell sections to form intermediate cabana shell members. The sections are stacked one upon the other with the wall of a section fitted within the enlarged lower end of the section immediately thereabove and with the walls of the sections substantially in vertical alignment. The base flange of the bottom section is fastened to a base skid which includes a filler material for weight and stability of the cabana.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 118 words
A portable toilet enclosure formed of at least two individual sections, comprising: a top section having an upper dome and a side wall, the side wall terminating in a downward and outward louver; and a bottom section having an open top, a side wall terminating in a downward and outward louver, and a flat, outwardly extending base; said top section being stacked on said bottom section with the side wall of said bottom section fitted within the louver of said top section, and with the side walls of both said sections being substantially vertically aligned, whereby the louver of said top sections prevents water from entering said bottom section at the region where said sections are stacked together.
Claim 2
Dependent Claim 118 words
A portable toilet enclosure formed of at least two individual sections, comprising: a top section having an upper dome and a side wall, the side wall terminating in a downward and outward louver; and a bottom section having an open top, a side wall terminating in a downward and outward louver, and a flat, outwardly extending base; said top section being stacked on said bottom section with the side wall of said bottom section fitted within the louver of said top section, and with the side walls of both said sections being substantially vertically aligned, whereby the louver of said top sections prevents water from entering said bottom section at the region where said sections are stacked together.
Claim 3
Dependent Claim 81 words
The construction as in claim 1 and further including: at least one center section between said top and bottom section; said center section having a side wall terminating in a downward and outward louver and having an open top and bottom; said center section being stacked between said top and bottom sections with the side wall of each section fitted within the louver of the section immediately thereabove and with the side walls of all sections being substantially in vertical alignment.
Claim 4
Dependent Claim 38 words
The construction as in claim 1 and further including a base skid secured to said bottom section, said skid adapted to receive a chemical toilet, said skid including a heavy filler material to provide stability for said enclosure.
Claim 5
Dependent Claim 52 words
The construction as in claim 2 wherein some of said sections include a vertically aligned cut-out to receive a frame; said construction further including: a frame secured to said cut-out areas and vertically spanning said sections; and a door mounted on said frame for convenient entry into and egress from said enclosure.
Claim 6
Dependent Claim 38 words
The construction as in claim 4 and further including: a base skid, including a heavy aggregate filler and attached to said bottom section for supporting and stabilizing said enclosure, and a chemical tank supported on said base skid.
Claim 7
Dependent Claim 141 words
The invention as defined in claim 1 and further including a base skid adapted to receive said bottom section, ssaid base skid comprising: a generally rectangular base pan having upwardly and outwardly projecting side walls to thereby define an interior portion of said skid; said base skid having internally raised formations interior of its side walls so that a part of the base skid is above the plane of the remainder of the base skid; said base skid including a relatively heavy filler material; and a covering over said filler material, said covering serving as a floor for the enclosure and adapted to receive a chemical toilet or the like; whereby the base skid may be fastened to the bottom of said bottom section with bolts so that the weight of said filler material provides a stable support for said enclosure.
Claim 8
Dependent Claim 25 words
The construction as in claim 6, wherein said covering is a foamed material which remains rigid and stable after being foamed over said base pan.
Claim 9
Dependent Claim 101 words
The construction as defined in claim 2, wherein each of said sections is initially a shell having: a dome-like roof; a side wall extending downwardly from said dome-like roof and terminating ain a bell-like enlarged lower end; and a base flange extending outwardly from the enlarged lower end of said side wall; whereby said dome-like roof may be removed to form A bottom section for said enclosure, said base flange may be removed to form a top section of said enclosure, and both said dome-like roof and said base flange may be removed to form a center section of said enclosure.
Claim 10
Dependent Claim 186 words
A portable toilet enclosure formed of at least three individual sections, comprising: a top section having an upper dome and a side wall, the side wall terminating in a downward and outward louver; a bottom section having an open top, a side wall terminating in a downward and outward louver, and a flat, outwardly extending base; and at least one center section between said top section and said bottom section; said center section having a side wall terminating in a downward and outward louver and having an open top and bottom; said top section being stacked on a center section with the side wall of the center section fitted within the louver of said top section and with a center section being stacked on said bottom section with the side wall of the bottom section fitted within the louver of the center section immediately thereabove, and with the side walls of all of said top, center and bottom sections being substantially in vertical alignment; whereby the louver of each section prevents water from entering the section therebeneath at the region where said sections are stacked together.
Claim 11
Dependent Claim 186 words
A portable toilet enclosure formed of at least three individual sections, comprising: a top section having an upper dome and a side wall, the side wall terminating in a downward and outward louver; a bottom section having an open top, a side wall terminating in a downward and outward louver, and a flat, outwardly extending base; and at least one center section between said top section and said bottom section; said center section having a side wall terminating in a downward and outward louver and having an open top and bottom; said top section being stacked on a center section with the side wall of the center section fitted within the louver of said top section and with a center section being stacked on said bottom section with the side wall of the bottom section fitted within the louver of the center section immediately thereabove, and with the side walls of all of said top, center and bottom sections being substantially in vertical alignment; whereby the louver of each section prevents water from entering the section therebeneath at the region where said sections are stacked together.
Claim 12
Dependent Claim 101 words
The invention as defined in claim 9, wherein each of said section is initially a shell having: a dome-like roof; a side wall extending downwardly from said dome-like roof and terminating in a bell-like enlarged lower end; and a base flange extending outwardly from the enlarged lower end of said side wall; whereby said dome-like roof may be removed to form a bottom section for said enclosure, said base flange may be removed to form a top section for said enclosure, and both said dome-like roof and said base flange may be removed to form a center section for said enclosure.
